Abstract:
Objective: Boron neutron capture therapy (BNCT) is an intensive research area for cancer researchers. Especially the side effects and inabilities of conventional therapies in some cases, directs researchers to find out a new cancer therapy methods such as BNCT. One of three important problem of BNCT is targeting of boron to tumor tissue. Borono Phenyl Alanine (BPA) and Borono Sodium Borocaptate (BSH) are already using in clinical studies as boron carriers. New boron carriers are searching for high yield boron accumulation in the tumor tissue. Methods: In this study, a novel 10B carrier was synthesized, ((2R)-4,5,6-trihydroxy-2-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)boronic acid (10B-DG), for BNCT studies. 10Boric Acid and 2-Deoxy-d-Glucose was complexed (10B-DG) through a low-high pH reaction and yield of complexion was tested with FTIR ATR and Liquid Chromatography Mass Spectrometry (LC/MS). Results: Confirmation studies have been carried out by HPLC and chromatograms have confirmed that Borono-2-Deoxy-d-Glucose synthesized with % 80 yield. Conclusions: This compound appears to be an alternative boron carrier for BNCT applications

Abstract:
Commonly found in the earth’s crust, boron happens to be the 51st element of the periodic table and is not found in its elemental state in nature. It is known that there are about 230 different boron minerals in nature. Turkey has the largest boron reserves in the world. In addition to this, Turkey’s boron minerals have the highest quality and production conditions that are more economical than other boron producing countries. For this reason, boron has great importance for Turkey and there is a significant demand for new areas of usage so that Turkey would be able to contribute to the national economy with these resources. The institute of BOREN (National Boron Research Institute) was established for this purpose in Turkey. This institute funds related projects for the extension of boron usage areas. One of the open sectors for innovation is textile technology.This study investigates the history of boron and its current situation in Turkey as well as the studies conducted regarding boron and its compounds especially in the textile field. Taking the available boron reserves in Turkey into consideration, the need for more research and development studies on boron as an environment-friendly element is clear for the textile industry.

Abstract:
High-grade gliomas present a significant challenge in neuro-oncology because of their aggressive nature and resistance to current therapies. Boron neutron capture therapy (BNCT) is a potential treatment method; however, the boron used by the carrier compounds—such as 4-borono-L-phenylalanine (L-BPA)—have limitations. This study evaluated the use of boron-conjugated 4-iodophenylbutanamide (BC-IP), a novel boron compound in BNCT, for the treatment of glioma. Using in vitro drug exposure experiments and in vivo studies, we compared BC-IP and BPA, with a focus on boron uptake and retention characteristics. The results showed that although BC-IP had a lower boron uptake than BPA, it exhibited superior retention. Furthermore, despite lower boron accumulation in tumors, BNCT mediated by BC-IP showed significant survival improvement in glioma-bearing rats compared to controls (not treated animals and neutrons only). These results suggest that BC-IP, with its unique properties, may be an alternative boron carrier for BNCT. Further research is required to optimize this potential treatment modality, which could significantly contribute to advancing the treatment of high-grade gliomas.

Abstract:
Background/Objectives: Boron neutron capture therapy (BNCT) is a promising approach for selectively targeting and destroying malignant cells using 10B isotopes. A significant challenge in BNCT lies in the development of efficient boron delivery systems that ensure adequate boron accumulation within tumor cells. This study aims to synthesize, characterize, and evaluate COSAN-functionalized nanoparticles (NP@I-COSAN) as a potential boron carrier for BNCT. Methods: Hybrid nanoparticles were synthesized by conjugating monoiodinated cobaltabisdicarbollides (I-COSAN) to commercially available acrylic polymer-based nanoparticles. Functionalization and cellular uptake were confirmed through FTIR, TGA, UV-Vis spectroscopy, and TEM/EDX analyses. Biocompatibility was evaluated by assessing cytotoxicity in HeLa cells and C. elegans as an in vivo model. Intracellular boron uptake was quantified using ICP-MS, with results compared to those obtained with 4-borono-L-phenylalanine conjugated to fructose (f-BPA). An in vitro BNCT proof-of-concept assay was also performed to evaluate therapeutic efficacy. Results: NP@I-COSAN demonstrated low cytotoxicity and efficient internalization in cells. ICP-MS analysis revealed stable boron retention, comparable to traditional boron agents. The BNCT assay further showed that NP@I-COSAN was effective in inducing tumor cell apoptosis, even at lower boron concentrations than conventional treatments. Conclusions: These results underscore the potential of NP@I-COSAN as an effective boron delivery system for BNCT, offering a promising strategy to enhance boron accumulation within tumor cells and improve treatment efficacy.

Abstract:
The amount and localization of boron-10 atoms delivered into tumor cells determines the therapeutic effect of boron neutron capture therapy (BNCT) and, consequently, efforts have been directed to develop fluorescence sensors to detect intracellular boronic acid compounds. Currently, these sensors are blue-emitting and hence are impracticable for co-staining with nucleus staining reagents, such as DAPI and Hoechst 33342. Here, we designed and synthesized a novel fluorescence boron sensor, BS-631, that emits fluorescence with a maximum emission wavelength of 631 nm after reaction with the clinically available boronic acid agent, 4-borono-l-phenylalanine (BPA). BS-631 quantitatively detected BPA with sufficiently high sensitivity (detection limit = 19.6 µM) for evaluating BNCT agents. Furthermore, BS-631 did not emit fluorescence after incubation with metal cations. Notably, red-emitting BS-631 could easily and clearly visualize the localization of BPA within cells with nuclei co-stained using Hoechst 33342. This study highlights the promising properties of BS-631 as a versatile boron sensor for evaluating and analyzing boronic acid agents in cancer therapy.

Abstract:
<strong>Objectives. </strong>Boron is a biological trace element which can be find in different natural compounds, but there is substantial and growing support for it to be classified as an essential nutrient for animals and humans. Previous studies suggest an active involvement of boron-containing compounds in the mediation of several biological reactions in the body, as inflammation and oxidative stress, which can influence occurrence of cardiovascular diseases and can amplify the risk factor impact. Although, the exact role of boron-containing compounds on human body has not yet been established, this work aims to study existing results with a special focus on cardiovascular health. The aim of this study was to review the literature and to detect the possible influence of boron compounds on cardiovascular health. <strong>Materials and methods. </strong>We made an analysis of more than 150 bibliographic sources that highlighted the boron and its compounds functions, and their impact on cardiovascular risk factors<strong>.</strong> <strong>Results.</strong> We found out that the most important compounds for human health are boron esters which can be taken from plant-based food and can be used directly in human cellular metabolism. These compounds have the ability to modulate a response to cardiovascular risk factors, such as oxidative stress and inflammation, but also can influence dyslipidemia, type II diabetes, smoking and obesity. <strong>Conclusions.</strong> Current studies suggest that a rich boron plant-based diet can have a potential cardioprotective effect and can be involved in reducing of risk factors for cardiovascular diseases.

Abstract:
Objective: The 18F-labeled Deoxy-D-Glucose exhibits high affinity to cancer tissue as a PET (Positron Emission Tomography) imaging agent for metastatic cancers. Complexation of 10B to 18F-DG complex may create a useful BNCT (Boron Neutron Capture Therapy) agent for cancer therapy. In previous studies, complexation and characterization of 10B with DG were evaluated and biodistribution analysis was completed successfully. Radioactive tracer labeled 10B-DG will be a useful approach to uses for BNCT applications. Methods: The 18F-DG synthesized by ion exchange and complexed with 10B(OH)3 via pH reactions. 18F-DG-10B complexation was assayed with Agilent 1260 Infinity HPLC-DAD and Agilent 6420 Triple Quad LC/MS. Complexed molecule defragmented and fragmentation products assayed with Agilent 6420 Triple Quad LC/MS for confirmation. Results: 10B-18F-DG complex was obtained with ion-exchange pH reaction successfully. Complexation of two 10B(OH)3 to 18F-DG was determined with Triple Quad LC/MS. Purification of 10B-18F-DG is currently in progress. Conclusions: Radio-labelled 10B-DG will supply new insight to research for BNCT studies. Cancer detection and therapy will be applicable in the same schedule with 10B-18F-DG complex.

Full text
Abstract:
Tolerance to high boron concentration in Brassica rapa was primarily due to low net boron uptake by the roots. However, in the two tolerant genotypes, 39–43% of boron uptake was retained in the tap roots, which limited boron accumulation in the leaves, and also contributed to boron tolerance. In the sensitive genotype, 99% of the increase in boron uptake caused by high soil boron accumulated in the leaves, particularly in the leaf margins. Despite higher transpiration rates, lower net boron uptake occurred in the tolerant genotypes. This result cannot be explained by passive boron uptake alone. Active boron efflux was probably responsible for differences in net boron uptake among tolerant and sensitive genotypes. Boron concentration was much lower in the cell walls than in the cell sap of leaves, indicating that storage of boron in the cell walls was not a tolerance mechanism. Despite high boron concentrations in the leaf symplasm, rates of photosynthesis, transpiration and growth were almost unaffected in the tolerant genotypes. The results demonstrate that boron tolerance in Brassica rapa involves boron exclusion at the root level, boron partitioning away from leaves and, as boron accumulates in leaves despite the first two mechanisms, boron tolerance of the leaf tissue itself.

Abstract:
Boron has gained significant attention in medical research due to its B-10 isotope’s high cross section for the reaction with thermal neutrons, generating ionizing particles that can eliminate cancer cells, propelling the development of boron neutron capture therapy (BNCT) for cancer treatment. The compound 4-borono-L-phenylalanine (BPA) has exhibited potential in BNCT clinical trials. Enhancing BPA uptake in cells involves proposing L-amino acid preloading. This study introduces a novel analytical strategy utilizing ICP-MS and single cell ICP-MS (SC-ICP-MS) to assess the effectiveness of L-tyrosine and L-phenylalanine preloading on human non-small cell lung carcinoma (A549) and normal Chinese hamster lung fibroblast (V79-4) models, an unexplored context. ICP-MS outcomes indicated that L-tyrosine and L-phenylalanine pre-treatment increased BPA uptake in V79-4 cells by 2.04 ± 0.74-fold (p = 0.000066) and 1.46 ± 0.06-fold (p = 0.000016), respectively. Conversely, A549 cells manifested heightened BPA uptake solely with L-tyrosine preloading, with a factor of 1.24 ± 0.47 (p = 0.028). BPA uptake remained higher in A549 compared to V79-4 regardless of preloading. SC-ICP-MS measurements showcased noteworthy boron content heterogeneity within A549 cells, signifying diverse responses to BPA exposure, including a subset with notably high BPA uptake. This study underscores SC-ICP-MS’s utility in precise cellular boron quantification, validating cellular BPA uptake’s heterogeneity.

The determination of a range of boron concentration in the soil solution, evaluation of the effect of physico-chemical soil properties on boron concentration in the soil solution as well verification whether boron quantity in the soil solution is sufficient for nutritional needs of selected plants cultivated in Poland were comprised. Average boron concentration in the soil solution of Poland&amp;rsquo;s cultivated soils ranges from 0.59 to 5.07 &amp;micro;mol/L and is differentiated by physico-chemical properties of soil. Taking into account decreasing effects of soil properties on the increase of boron concentration in the soil solution, the soil properties can be arranged as follows: organic C &amp;gt;&lt;br /&gt;soil abundance in available boron &amp;gt; soil texture &amp;gt; soil pH. The minimum boron quantity observed in the soil solution of Poland&amp;rsquo;s cultivated soils was not sufficient to fulfil nutritional needs of the plants. The maximum boron quantity observed secured nutritional needs of cereals and potatoes but not those of rape plants and sugar beets. Based on the study it can be concluded that the measurement of the concentration of boron in the soil solution can be used in the diagnosis of deficiency of this element for crops.

<strong>Abstract:</strong> The experiment conducted at the Agronomy Field Laboratory, University of Rajshahi, from January to June 2022, investigated the effects of different doses of boron and magnesium on the growth and yield of boro rice. The study included two rice varieties (BRRI dhan29 and BRRI dhan58) and three treatment levels: control (only recommended NPK), low rate of boron and magnesium (8 kg/ha and 15 kg/ha), and high rate of boron and magnesium (15 kg/ha and 24 kg/ha), arranged in a Randomized Complete Block Design. Results showed that BRRI dhan58 outperformed BRRI dhan29 across various growth parameters. BRRI dhan58 recorded the highest values for plant height (89.95 cm), total tillers per hill (17.29), effective tillers per hill (12.48), chlorophyll content (SPAD 46.08), panicle length (20.20 cm), total grains per panicle (164.11), effective grains per panicle (128.67), 1000-grains weight (23.10 g), grain yield (6.27 t/ha), straw yield (7.88 t/ha), and biological yield (14.15 t/ha).Among the treatments, the highest values for similar parameters were observed in the high rate of boron and magnesium treatment (T<sub>3</sub>). For interaction effects, the combination of BRRI dhan58 and high rate of boron and magnesium (V<sub>2</sub>T<sub>3</sub>) yielded the best results, including highest plant height (93.54 cm), total tillers per hill (18.11), effective tillers per hill (13.67), chlorophyll content (SPAD 48.45), panicle length (20.65 cm), total grains per panicle (175.11), effective grains per panicle (142.45), 1000-grains weight (23.47 g), grain yield (6.56 t/ha), straw yield (8.24 t/ha), and biological yield (14.79 t/ha).The study concluded that BRRI dhan58, combined with the high rate of boron and magnesium, is the most effective for maximizing yield, recommending this combination for farmers. <strong>Keywords:</strong> Boro rice, Boron and magnesium, chlorophyll content, Rice yield. <strong>Title:</strong> INFLUENCE OF DIFFERENT DOSES OF BORON AND MAGNESIUM ON THE GROWTH AND YIELD OF BORO RICE CULTIVARS <strong>Author:</strong> Md.

Abstract:
In this study, it was aimed to determine the water-borne and food-borne boron accumulation in the liver and muscle tissues of Gold Fish (Carassius auratus Linnaeus, 1758). For each treatment, 12 individuals were. The water-borne boron treatments were applied as boron acid concentration of 1 mg/L, 10 mg/L and 20 mg/L in the aquarium water, while the food-borne boron treatments were prepared food contained the defined levels of boron (1 mg/kg, 5 mg/kg and 10 mg/kg) as boric acid. The boron levels in the tissues were determined by an ICP-MS procedure. The maximum boron concentration was found in the 20mg/L water borne boron treatment in the liver tissue (1.78±0.02 mg/kg). In the water-borne boron treatments, the maximum Transfer Factor (TF) was found in the 20mg/L boron concentration, and TF values were increased when the boron concentrations were decreasing. In the 1 mg/kg food-borne boron treatment, TF was found as 0, and increasing concentration of boron in the food caused an increase in TF reached about 0.06. This study suggested that the target organ for boron accumulation is the liver rather than the muscles and the accumulation of food-borne boron is lower when comparing water-borne boron.

Abstract:
Combustion models of main components of condensed combustion products (CCP) of boron-containing solid propellants: boron, boron carbide, boron nitride, and carbon are analyzed. Using the known experimental data, the parameters of the combustion model of boron carbide and boron nitride particles are determined. Using the models of combustion of boron, B4C, BN and carbon particles, parametric calculations of the combustion of both individual abovementioned particles and their mixture, which simulates the composition of the CCP of boron-containing solid propellant, have been carried out. Calculations have shown that combustion of BN has the least effect on the completeness of CCP combustion. This is due to its low calorific value and low content in CCP. Ceteris paribus, carbon particles burn the fastest; however, their contribution to the completeness of CCP combustion is less than that of boron and boron carbide due to their lower calorific value.

Abstract:
Although 4-borono-l-phenylalanine (4-BPA) is currently the only marketed agent available for boron neutron capture therapy (BNCT), its low water solubility raises concerns. In this study, we synthesized 3-borono-l-phenylalanine (3-BPA), a positional isomer of 4-BPA, with improved water solubility. We further evaluated its physicochemical properties, tumor accumulation, and biodistribution. The water solubility of 3-BPA was 125 g/L, which is more than 100 times higher than that of 4-BPA. Due to the high water solubility, we prepared the administration solution of 3-BPA without a solubilizer sugar, which is inevitably added to 4-BPA preparation and has adverse effects. In in vitro and in vivo experiments, boron accumulation in cancers after administration was statistically equivalent in both sugar-complexed 3-BPA and 4-BPA. Furthermore, the biodistribution of 3-BPA was comparable with that of sugar-complexed 3-BPA. Since 3-BPA has high water solubility and tumor targetability equivalent to 4-BPA, 3-BPA can replace 4-BPA in future BNCT.

Abstract:
Boron is the only element known to be essential for plants, but only circumstantial evidence for essentiality exists in animals. We report here that boron is essential for the embryonic development of zebrafish (Danio rerio). Zebrafish were maintained in water with a boron concentration of 0.1 micromol l-1 or supplemented to a concentration of 45 micromol l-1 using ultrapure boric acid. Both groups were fed boron-depleted brine shrimp. This procedure depleted the boron content of the blastulas from low-boron parents to only 5 % of the boron content of the blastulas from boron-supplemented parents. Sperm from low-boron males successfully fertilized eggs from low-boron females, but 92 % of the embryos died within 10 days. The early cleavage stage of development was the most sensitive to boron deficiency. Of the fertilized embryos, 46% did not live to complete the blastula stage. Repletion of low-boron embryos during the first hour after fertilization rescued them from death. These observations provide strong evidence that boron is essential for zebrafish development.

Abstract An overview is given of the recently proposed method for computation of the electrostatic potential (ESP) of dynamic charge densities derived from multipole models [C. B. Hubschle, S. van Smaalen, J. Appl. Crystallogr. 2017, 50, 1627]. The dynamic ESP is presented for the multipole models of the boron polymorphs α-B12 and γ-B28, and stoichiometric boron carbide B13C2. Minimum values of the ESP are conspiciously equal at approximately −1 electron/Å. Regions with the ESP close to its minimum value form an extended network throughout the crystal structures at locations far away from atoms and bonds. Boron and boron carbide are extended solids containing an infinite network of strong chemical bonds. We have shown that for such solids, the ESP can usefully considered on Hirshfeld surfaces encompassing groups of atoms. Accordingly, we discuss bonding in boron and boron carbide with aid of the ESP on the Hirsfeld surface encompassing a B12 icosahedral cluster. The structure of the ESP corroborates the interpretation of the bonding characteristics previously proposed for α-B12, γ-B28 and B13C2.

In this study boron removal capacities of different microorganisms were tested. Candida tropicalis, Rhodotorula mucilaginosa, Micrococcus luteus, Bacillus thuringiensis, Bacillus cereus, Bacillus megaterium, Bacillus pumilus, Pseudomonas aeruginosa and Aspergillus versicolor were examined for their boron bioaccumulation capacities in simulated municipal wastewater. A. versicolor and B. cereus were found as the most boron-tolerant microorganisms in the experiments. Also boron bioaccumulation yield of A. versicolor was 49.25% at 15 mg/L boron concentration. On the other hand biosorption experiments revealed that A. versicolor was more capable of boron removal in inactive form at the highest boron concentrations. In this paper maximum boron bioaccumulation yield was detected as 39.08% at 24.17 mg/L and the maximum boron biosorption yield was detected as 41.36% at 24.01 mg/L boron concentrations.

Abstract:
Background: Boron neutron capture therapy (BNCT) is a nuclear reaction-based tumor cell-selective particle irradiation method. High-dose methotrexate and whole-brain radiation therapy (WBRT) are the recommended treatments for primary central nervous system lymphoma (PCNSL). This tumor responds well to initial treatment but relapses even after successful treatment, and the prognosis is poor as there is no safe and effective treatment for relapse. In this study, we aimed to conduct basic research to explore the possibility of using BNCT as a treatment for PCNSL. Methods: The boron concentration in human lymphoma cells was measured. Subsequently, neutron irradiation experiments on lymphoma cells were conducted. A mouse central nervous system (CNS) lymphoma model was created to evaluate the biodistribution of boron after the administration of borono-phenylalanine as a capture agent. In the neutron irradiation study of a mouse PCNSL model, the therapeutic effect of BNCT on PCNSL was evaluated in terms of survival. Results: The boron uptake capability of human lymphoma cells was sufficiently high both in vitro and in vivo. In the neutron irradiation study, the BNCT group showed a higher cell killing effect and prolonged survival compared with the control group. Conclusions: A new therapeutic approach for PCNSL is urgently required, and BNCT may be a promising treatment for PCNSL. The results of this study, including those of neutron irradiation, suggest success in the conduct of future clinical trials to explore the possibility of BNCT as a new treatment option for PCNSL.

Abstract:
This study aims to improve the structural strength of the commonly used Ti-15Zr alloy in dental applications by investigating the effects of low boron additions. Ti-15Zr alloys containing 1-4% boron have been produced by vacuum arc melting. The phase ratios in the microstructure of the produced alloys vary according to the boron content. With increasing boron content, the ratio of TiB compound in the phase structure increases. The hardness of Ti-Zr-B alloys exhibited a notable increase in correlation with rising boron content. Measured hardness values of 36.31, 39.50, 44.14, and 53.40 displayed a clear upward trend with higher boron percentages. The tensile strength of the Ti-Zr-B alloys exhibits a trend of initially increasing with boron content, reaching its highest value of 888 MPa at 1% boron. The yield strength follows a similar with tensile strengh, with an initial rise from 449 MPa at 0% boron to a peak of 562 MPa at 1% boron content. Beyond this point, the yield strength slightly decreases to 469 MPa at 2% boron but sharply drops to 186 MPa at 4% boron content. As boron content increases in the Ti-Zr-B alloys, the percentage elongation, indicating the material's plastic deformation capacity before fracture, consistently decreases from 17.03% at 0% boron to 0.70% at 4% boron content.

Abstract:
Boron neutron capture therapy (BNCT) is a binary therapeutic technique employing a boron agent to be delivered to the tumor site followed by the irradiation of neutrons. Biofunctional molecules/nanoparticles labeled with F-18 can provide an initial pharmacokinetic profile of patients to guide the subsequent treatment planning procedure of BNCT. Borono phenylalanine (BPA), recognized by the l-type amino acid transporter, can cross the blood-brain barrier and be accumulated in gliomas. The radiofluoro BNCT agents are reviewed by considering (1) less cytotoxicity, (2) diagnosing and therapeutic purposes, (3) aqueous solubility and extraction route, as well as (4), the trifluoroborate effect. A trifluoroborate-containing amino acid such as fluoroboronotyrosine (FBY) represents an example with both functionalities of imaging and therapeutics. Comparing with the insignificant cytotoxicity of clinical BPA with IC50 &gt; 500 μM, FBY also shows minute toxicity with IC50 &gt; 500 μM. [18F]FBY is a potential diagnostic agent for its tumor to normal accumulation (T/N) ratio, which ranges from 2.3 to 24.5 from positron emission tomography, whereas the T/N ratio of FBPA is greater than 2.5. Additionally, in serving as a BNCT therapeutic agent, the boron concentration of FBY accumulated in gliomas remains uncertain. The solubility of 3-BPA is better than that of BPA, as evidenced by the cerebral dose of 3.4%ID/g vs. 2.2%ID/g, respectively. While the extraction route of d-BPA differs from that of BPA, an impressive T/N ratio of 6.9 vs. 1.5 is noted. [18F]FBPA, the most common clinical boron agent, facilitates the application of BPA in clinical BNCT. In addition to [18F]FBY, [18F] trifluoroborated nucleoside analog obtained through 1,3-dipolar cycloaddition shows marked tumoral uptake of 1.5%ID/g. Other examples using electrophilic and nucleophilic fluorination on the boron compounds are also reviewed, including diboronopinacolone phenylalanine and nonsteroidal anti-inflammatory agents.

Abstract:
Abstract Objective Boron neutron capture therapy (BNCT) is a noninvasive radiation therapy method for cancer treatment. In BNCT, 4-borono-2-[18F]-fluoro-L-phenylalanine (18F-FBPA) PET has been employed to estimate 10B accumulation in target tumors and normal tissues if 10B borono-L-phenylalanine (10B-BPA) is used as a boron carrier. The purpose of the current study was to evaluate the total distribution volume (Vt) of 18F-FBPA in normal organs of healthy volunteers by kinetic analysis and to estimate boron concentration in normal organs for the therapeutic dose of 10B-BPA using obtained Vt values. Methods Six healthy volunteers were injected with 18F-FBPA (3–5 MBq/kg), and 7 PET-CT scans were performed subsequently. 18F-FBPA radioactivity in whole blood and plasma was measured before, and eight times after the injection. PET images were analyzed by PMOD software. Twelve volumetric regions of interest including the brain, heart, right lung, spleen, liver, parotid salivary glands, esophagus, stomach, pancreas, intestines, and bone marrow were drawn manually for each subject and analyzed with the Logan plot and two Ichise multilinear analyses (MA1 and MA2). The better model was defined by several goodness-of-fit parameters and residual distribution. After Vt values had been derived, boron concentration was estimated in ppm for the 10B-BPA-fructose (10B-BPA-fr) dose 30 g 1 and 2 h post-injection using Vt and interpolated plasma activity data. Results The Ichise MA2 model showed the best fit among all models. Akaike Information Criterion (AIC) was the lowest for the Ichise’s MA2 in all regions (mean AIC value − 14.0) comparing to the other models (Logan plot mean AIC 31.4; Ichise MA1 model mean AIC − 4.2). Mean Vt values of the Ichise MA2 model ranged from 0.94 ± 0.14 ml/ml in the pancreas to 0.16 ± 0.02 ml/ml in the right lung. Estimated boron concentration for 10B-BPA-fr had the highest value in the pancreas (14.0 ± 1.9 ppm 1 h after, and 5.7 ± 1.7 ppm 2 h after the 18F-FBPA administration) and the lowest value in the right lung (2.4 ± 0.3 ppm 1 h, and 1.0 ± 0.3 ppm 2 h post-injection). Conclusion The 10B concentration in normal tissues was best estimated using Vt values of 18F-FBPA with the Ichise multilinear analysis 2 (MA2).

Abstract:
The influence of addition of small amounts of boron and nitrogen on the microstructure formed by austenite decomposition in low-alloyed manganese steels was investigated. In order to understand microstructural changes by addition of boron and nitrogen, Auger electron spectroscopy was used for analyzing prior austenite grain boundaries in steels doped with phosphorus, boron and nitrogen. The results by microstructure observation showed that the formation of Widmanstätten ferrite was suppressed by addition of a small amount of boron in the steels, whereas Widmanstätten ferrite appears to be formed again by addition of boron and nitrogen. The Auger spectra showed that small particles of boron nitride were detected on grain boundaries in steel doped with boron and nitrogen, while boron was segregated at grain boundaries in steel with boron. This indicates that segregation of boron at grain boundaries and/or sub-boundaries may suppress the formation of Widmanstätten ferrite, while the formation of boron nitride seems to be ineffective to suppression of the formation of Widmanstätten ferrite in steels doped with boron and nitrogen.

BRRI dhan28). The experimental area belongs to High Ganges River Floodplain under Agro Ecological Zone-11 (AEZ-11). The experiment was constructed with two factors viz., factor A (sulphur) and factor B (boron) with three level of doses of each, i.e., S<sub>0</sub>: without sulphur (control), S<sub>1</sub>: 20 kg S ha<sup>-1</sup>, S<sub>2</sub>: 30 kg S ha<sup>-1</sup>, and B<sub>0</sub>: without boron (control), B<sub>1</sub>: 2 kg B ha<sup>-1</sup>, B<sub>2</sub>: 3 kg B ha<sup>-1</sup>. The experiment was conducted in a Randomized Complete Block Design (RCBD) with three replications. The results revealed that S and B significantly influenced the growth, yield contributing traits and yield of rice, and the treatment of S1B1 (20 kg S ha<sup>-1</sup> with 2 kg B ha<sup>-1</sup>) performed the best results of number of tillers hill<sup>-1</sup> (28.78), panicle length (26.94 cm), grains panicle<sup>-1</sup> (177.57), filled grains panicle<sup>-1</sup> (150.27), 1000-grain weight (29.75 g), highest grain (6.30 t ha<sup>-1</sup>), straw (5.91 t ha<sup>-1</sup>), and biological yield (12.21 t ha<sup>-1</sup>) and HI (51.60%).

Abstract:
Boron is rare in the cosmos because its nucleus is “fragile.” So, how does one get from the interstellar medium, where boron was first produced, to Earth's upper continental crust where boron is concentrated in deposits containing remarkably diverse suites of boron minerals? Processes that led to the formation of continental crust also concentrated boron, which is preferentially incorporated into melts and aqueous fluids. Deposits with high boron-mineral diversity include granitic pegmatites, peralkaline intrusions, boron-enriched skarns, and evaporite deposits. Despite the loss of boron minerals from the geologic record due to their ready solubility in water and breakdown at low temperatures, the increase in boron-mineral diversity with time is real, and is accelerated during supercontinent assembly.

Abstract:
It is convenient to analyze the distribution of boron in high carbon steel with boron, simply using neutron-induced radiography with a neutron fluency of 1.9 x 1013 [cm-2]. It was revealed by the neutron-induced radiography that the distribution of boron was dependent on boron contents, graphitizing temperature and time. The density of boron track increased with increasing boron contents. But the density of the boron track and graphite in high carbon steel graphitized at 700°C is higher than that of high carbon steel graphitized at 750°C. The density of graphite in high carbon steel also depends upon the content of boron and the graphitizing temperature. The shape of the boron track was changed from sphere to rod type when annealed at 800°C, in steel containing 50ppm of boron, due to different phases of boride. The distribution of boron segregation or boronrich precipitates in high carbon steel was well documented with a neutron-induced radiography, but the direct relationship between graphite and boron was not clarified by it. Furthermore, the analysis of electron probe X-ray microanalyzer (EPMA) also showed that the high amount of boron coexisted with carbon in graphite in high carbon steel.

Abstract A field experiment was conducted in one of fields of research experiments affiliated to College of Agricultural Engineering Sciences / University of Baghdad during spring season of 2022 to know effect of humic acid and levels of zinc and boron on chemical behavior of boron in a calcareous soil with a clay loam texture. Field experiment included studying effect of three factors (adding humic acid, zinc and boron) using a randomized complete block design (RCBD) with three replicates and planting sunflowers (Helianthus annuus L.) Shmos cultivar. Sequential extraction of boron in soil was carried out. Results showed addition of boron led to a significant increase in concentration of total boron, available boron, boron bound to carbonate minerals, boron bound to oxides in soil, and boron bound to organic matter, as concentrations reached 4.1522, 0.3886, 0.8114, 0.3290, and 0.6219 mg B kg−1 soil for treatments B1 for total boron and B2 for rest of boron forms in soil, respectively. Added zinc had a significant effect on increasing availability of boron in soil, Zn2 treatment was significantly superior, reaching 0.3605 mg B kg−1 soil and a total of 4.1522 mg B kg−1 soil for Zn1 treatment, while effect was negative on concentrations of boron associated with carbonate minerals (Zn0 treatment) and associated with organic matter (Zn0 treatment) and remainder (Zn1 treatment), as concentration reached 0.7846, 0.4860 and 2.6063 respectively. Humic acid had a significant effect on increasing concentration of available boron bound to organic matter; H1 treatment was significantly superior, giving highest concentration of 0.3001 and 0.4187 mg B kg−1 soil, respectively, while effect was negative on concentration of boron bound to carbonates, bound to oxides, residual and total, as concentration reached 0.8291, 0.2567, 2.5576 and 4.2520 mg B kg−1 soil for treatment H0 for above boron images, respectively. results of twice and triple interaction between three factors (boron, zinc and humic acid) showed significant differences in increasing concentration of available and total boron, bound to oxides and bound to organic matter in soil, while twice and triple interaction had a significant negative relationship in concentrations of boron bound to carbonate minerals in soil.

Abstract:
The origin of boron in modern salt lakes has long been a controversial subject. This study focuses on the boron geochemistry of Lakkor Co salt lake, located on the Shiquanhe-Lakkor Co-Yongzhu-Jiali Ophiolite Mélange Zone (SYMZ). Lakkor Co is one of the main boron-rich salt lakes in the Tibetan plateau where the boron concentration ranges from 401 to 849 mg L-1. The boron isotope value ( δ 11 B ) of the carbonate deposit within the Lakkor Co region is -28.08‰. The boron isotope value of the Somme river decreases from -9.97‰ to -11.15‰ after it flows through the carbonate deposit region, indicating that the carbonate deposit in this region releases boron, which has a more negative isotope value. However, the boron isotope value of Bai Kok river increases from -15.63‰ to -13.76‰, when it flows through the Quaternary clay region in Ganga Co, indicating that the carbonate deposit undergoes a process of boron adsorption. It can be concluded that the Quaternary carbonate deposits may be a source of boron and also serve as a temporary boron reservoir, thus playing an important role in the formation of modern salt lake boron deposits in Tibet.

Abstract:
Boron (B) is essential for the development and functioning of organisms, involving their growth, health, and development of plants, animals, and humans. Nevertheless, the increasing use of boron in various applications has led to environmental problems and health issues. Several separation technologies have been employed to remove boron, and adsorption is one such technology that utilizes adsorbents to address solutions containing extremely low levels of boron. This finding investigates the residual boron from a synthesized solution through adsorption, using CRB05 as the adsorbent. The impact of adsorbent dosage, contact time, boron concentration, and pH on residual boron was examined. The findings indicate that the pH plays a substantial role impact on the residual boron efficiency from all adsorbents. The highest residual of boron was achieved at pH 4.5, adsorbent dosage 1125 mg/L, time 255 minutes, and concentration 1150 mg/L with 98% removal. Adsorption of boron using CRB05 proved to be an effective method for recovering boron from the synthesis solution. The findings of this study enhance our comprehension of the adsorption behavior of CRB05 and provide insights into the optimal operating conditions for efficient boron removal.
