Abstract:
Abstract Background β-d-glucan (BG) detection was first available in Thailand in 2016 to aid diagnosis of invasive fungal infections (IFIs). Given a paucity of real-world experience of BG use in resource-limited countries, this study was conducted to describe appropriateness of BG testing and sequelae of BG results. Methods A retrospective study included all patients with at least 1 BG ordered at King Chulalongkorn Memorial Hospital, Bangkok, Thailand during March 2016 to December 2018. Descriptive statistics were used. Results 83 patients were tested by BG assay (Fungitell, Associates of Cape Cod, Inc.): 6 with hematopoietic stem cell transplant, 12 with solid-organ transplant, 20 with active cancer receiving chemotherapy, 34 receiving high dose steroids (≥20 mg/day of prednisone for ≥3 weeks) and 11 with other conditions. Seventy-three patients were tested under infectious disease (ID) service’s recommendations. There were 13 and 20 cases of proven and probable IFIs, respectively. Among 13 proven IFIs, there were 11 positive, 1 indeterminate and 1 negative (mucormycosis) BG results. Among 49 cases with positive BG results, 24 were determined to be false-positive results. Median turn-around time for BG results was 16 (IQR: 9–23) days. Due to high turn-around time, only 8 patients were started on antifungal agent(s) and 3 underwent bronchoscopy due to positive BG results. All proven IFI cases were started on antifungal treatment prior to BG availability. Conclusion Approximately 87% of BG use in Thailand was ordered in patients with risk factors for IFIs. This could be due to majority of BG test was recommended by ID specialist. Despite being used in right clinical context, 49% had false-positive BG results. Another barrier of BG use in Thailand was high turn-around time due to small numbers of BG ordered and relative high cost to run the assay. Therefore, the utility of BG for aiding diagnosis or management of fungal infection in our setting is limited. Disclosures All authors: No reported disclosures.

Abstract:
Anacystis nidulans is a small, rod-shaped, unicellular, colonial, obligatory phototrophic microalga isolated from Sambhar Lake, Jaipur (Rajasthan). To find out the best inorganic composition cultures were grown in five different defined inorganic medium such as Modified BG-11 medium (pH 7.31), BG-11 medium (7.1), CHU-10 (pH 7.65), Zarrouk’s medium (pH 10.2) and Kratz & Myer medium (pH 9.5) and kept at the temperature of 25 ± 2°C, illuminated with white fluorescent lamps at a light intensity of 2.5 Klux with 12:12 hours light/dark photoperiod in departmental laboratory. Protein content is determined by Bradford assay and qualitatively by SDS-PAGE. Protein expression levels were determined through densitometry. Highest protein and amino acid content were obtained in Modified BG-11 medium as compared to other medium. Two polypeptides of 54.3 and 56.2 kDa were uniquely observed, but the genotype of 35.8 kDa polypeptide was completely degraded under Modified BG-11 inorganic formulation. 35.8, 54.3, 56.2 and 61.8 kDa polypeptides were completely degraded in Zarrouk’s as well as Kratz and Myer medium. The expression of some polypeptides of 14.0, 34.1, 42.3, 45.9, 49.5 and 75.0 kDa were greatly reduced and expressed only 1mm level in Zarrouk’s and Kratz and Myer medium. Quantity of free amino acids maximum was in Modified BG-11 medium and minimum was in the Kratz and Myer Medium. Total 17amino acids were observed in the HPLC chromatogram. No detectable amount of asparagine, glutamine and tryptophan were found throughout the course of the algal life cycle

Abstract:
Bottle gourd [Lagenaria siceraria (Molina) Standl.] landraces are widely grown in South Africa, and genetic diversity analysis is necessary to identify promising genotypes for breeding or systematic conservation. Sixty-seven diverse bottle gourd landraces were genotyped using 14 selected simple sequence repeat (SSR) markers. The number of alleles detected per marker ranged from 4 to 11, with a total of 86 putative alleles being amplified. Allele sizes ranged from 145 to 330 base pair (bp). Number of effective alleles (Ne) ranged from 1.58 to 6.14 with a mean of 3.10. Allelic richness varied from 3.00 to 8.90 with a mean of 5.23. Expected heterozygosity (He) values ranged from 0.37 to 0.84 with a mean of 0.65. The mean polymorphic information content (PIC) was 0.57. Jaccard’s coefficient of similarity values ranged from 0.00 to 1.00, with a mean of 0.63. Analysis of molecular variance (AMOVA) revealed that 79%, 17%, and 4% of the variation in bottle gourd landraces was attributable to among landraces, within landraces, and between populations, respectively. The study established the existence of considerable genetic diversity among South African bottle gourd landraces. Unique landraces such as BG-4, BG-6, BG-8, BG-9, and BG-15 from cluster I; BG-55, BG-42, BG-57, and BG-58 from cluster II; BG-28, BG-23, BG-29, and BG-34 from cluster III were selected based on their highest dissimilarity index. These could be useful for bottle gourd breeding and systematic conservation.

Abstract:
PURPOSE The major mechanism of resistance to alkylnitrosourea therapy is the DNA repair protein O6-alkylguanine-DNA alkyltransferase (AGT), which removes chlorethylation or methylation damage from the O6-position of guanine. O6-benzylguanine (O6-BG) is an AGT substrate that inhibits AGT by suicide inactivation. We conducted a phase I trial to define the presurgical dose required for depletion of tumor AGT activity in patients with malignant glioma. MATERIALS AND METHODS Patients were to be treated 18 hours before craniotomy with intravenous doses that ranged between 40 and 100 mg/m2 given over 1 hour. Resected tumor was snap-frozen in liquid nitrogen and AGT activity analyzed by high-pressure liquid chromatography (HPLC). Up to 13 patients were treated at a specific dose of O6-BG, with a target end point of > or = 11 of 13 patients with undetectable tumor AGT levels (< 10 fmol/mg protein). RESULTS Thirty patients with malignant gliomas were enrolled, with 11 of 11 patients treated at 100 mg/m2 O6-BG demonstrating tumor AGT levels less than 10 fmol/mg protein. No toxicity was noted in any patient treated. CONCLUSION These results indicate that 100 mg/m2 of O6-BG can maintain tumor AGT levels less than 10 fmol/mg protein for at least 18 hours after treatment, a time interval in which bis(2-chloroethyl)nitrosourea (BCNU)-induced chloroethyl adducts are fully converted into interstrand cross-links. A 100-mg/m2 dose of O6-BG will be used in combination with BCNU in another phase I trial designed to determine the maximal-tolerated dose of BCNU.

Abstract:
9566 Background: Beta glucans are complex, naturally occurring polysaccharides that prime leucocyte dectin and CR3 receptors. Based on our preclinical observations that oral barley-derived (1→3,1→4)-β-D-Glucan (BG) synergizes with the murine anti-GD2 antibody 3F8 against neuroblastoma (NB) (Clin Cancer Res 8:1217), we conducted a phase I study to determine the safety of the combination of BG and 3F8 in patients with resistant NB. Methods: Heavily pre-treated patients with recurrent or refractory advanced stage NB were treated with 3F8/BG. Each cycle consisted of intravenous (IV) 3F8 at a fixed dose of 10 mg/m2/day ×10 days, plus oral BG dose escalated from 10 to 80 mg/kg/day ×10 days in 4 cohorts of 6 patients each. Patients without human anti-mouse antibody (HAMA) could be re-treated up to a total of 4 cycles. Results: Twenty-three patients with stage 4 and one with stage 3 NB (M:F = 11:13; median age 8 (range 2–19) years completed 47 cycles of therapy with 3F8/BG. 8 patients had progressive disease (PD) while 16 had stable refractory NB (SD) at enrollment. All patients completed at least one cycle of therapy and were evaluated for toxicity and response. Maximum tolerated dose for BG was not reached. Two patients developed dose-limiting toxicities (DLT). Both had grade 4 thrombocytopenia after completing one cycle of treatment: one at BG dose of 20mg/kg/day and the other at 40 mg/kg/day. Both cases responded to therapy with a short course of ITP (idiopathic thrombocytopenic purpura) therapy; one subsequently developed chronic ITP. There were no other >grade 2 toxicities related to 3F8/BG therapy. 14, 4, 2 and 6 patients completed 1, 2, 3 and 4 cycles respectively. Reasons for withdrawal in patients who did not complete 4 cycles were PD in 10, persistently elevated HAMA in 6 and DLT in 2. Overall 11 patients had SD and 13 PD. 14/23 patients with positive MIBG scans prior to therapy demonstrated improvement after one cycle. Responses did not correlate with BG dose received. 7 patients, all with residual disease survive at a median of 40 (range 24–45) months post-treatment. Conclusions: 3F8/BG is well tolerated and shows activity against resistant NB. Further clinical investigation of this novel combination is warranted. No significant financial relationships to disclose.

Abstract:
Background: Availability of a highly accurate in-hospital automated blood glucose (BG) monitor could facilitate implementation of intensive insulin therapy protocols through effective titration of insulin therapy, improved BG control, and avoidance of hypoglycemia. We evaluated a functional prototype BG monitor designed to perform frequent automated blood sampling for glucose monitoring. Methods: Sixteen healthy adult volunteer subjects had intravenous catheter insertions in a forearm or hand vein and were studied for 8 hours. The prototype monitor consisted of an autosampling unit with a precise computer-controlled reversible syringe pump and a glucose analytical section. BG was referenced against a Yellow Springs Instrument (YSI) laboratory analyzer. Sampling errors for automated blood draws were assessed by calculating the percent of failed draws, and BG data were analyzed using the Bland and Altman technique. Results: Out of 498 total sample draws, unsuccessful draws were categorized as follow: 11 (2.2%) were due to autosampler technical problems, 21 (4.2%) were due to catheter-related failures, and 37 (7.4%) were BG meter errors confirmed by a glucometer-generated error code. Blood draw difficulties or failures related to the catheter site (e.g., catheter occlusion or vein collapse) occurred in 6/15 (40%) subjects. Mean BG bias versus YSI was 0.20 ± 12.6 mg/dl, and mean absolute relative difference was 10.4%. Conclusions: Automated phlebotomy can be performed in healthy subjects using this prototype BG monitor. The BG measurement technology had suboptimal accuracy based on a YSI reference. A more accurate BG point-of-care testing meter and strip technology have been incorporated into the future version of this monitor. Development of such a monitor could alleviate the burden of frequent BG testing and reduce the risk of hypoglycemia in patients on insulin therapy.

Abstract:
SUMMARY Objectives: This study evaluated effects of Bioglass 45S5 (BG) and Biosilicate (BS) remineralization on the chemical composition and bond strength of control dentin (CD) and bleached dentin (BD) surfaces. Methods and Materials: Dentin bleaching treatment was performed using the walking bleaching technique with 0.01 g of sodium perborate and 0.5 mL of 3% hydrogen peroxide for 14 days. Remineralization treatment was carried out by rubbing a remineralization solution (0.015 g of BG or BS diluted in 1.35 mL of distilled water) on the etched dentin surface for 30 seconds. Micro-Raman spectroscopy (MRS) was used to quantitatively analyze the mineral matrix ratios of CD and BD (n=5) after remineralization treatment with BG and BS over 15 days of incubation in artificial saliva. The CD and BD discs (n=10) with and without remineralization treatment with BG and BS were restored using a two-step etch-and-rinse adhesive system (Optibond S, Kerr) and five layers of 1-mm-thick composite resin (Filtek Z250, 3M ESPE). The restored dentin discs were sectioned into nine bonded beams with cross-sectional areas of approximately 0.9 mm2 and tested for microtensile bond strength (μTBS). The dentin surface of one fractured beam per tooth was submitted to MRS to characterize the physicochemical composition (n=10) at the interface. The data were analyzed using one-way analysis of variance and the Tukey-Kramer post hoc test (p&lt;0.005). Results: MRS bioactive analyses revealed that both BG and BS promoted increased mineral matrix ratios in the CD and BD. Significantly higher μTBS values were found after CD treatment with BG (CD: 57 MPa±11; CD-BG: 78 MPa±15) and when BG and BS were applied to the BD (BD: 42 MPa±5; BD-BG: 71 MPa±14; BD-BS: 64 MPa±11) (p&lt;0.005). The MRS analysis of the fractured dentin beam showed that the remineralization treatment significantly increased the dentin relative mineral concentration and promoted the appearance of new interface peaks, indicating a chemical interaction (p&lt;0.005). Conclusion: Remineralization of BD is an effective therapy to restore damage caused by dentin bleaching and acid conditioning. This approach not only increases dentin mineral compounds but also improves dentin's ability to interact chemically with the adhesive system.

Abstract:
Background: In recent clinical trials, use of the MyGlucoHealth blood glucose meter (BGM) and electronic diary was associated with an unusual reporting pattern of glycemic data and hypoglycemic events. Therefore, the performance of representative BGMs used by the patients was investigated to assess repeatability, linearity, and hematocrit interference in accordance with regulatory guidelines. Method: Ten devices and 6 strip lots were selected using standard randomization and repeatability procedures. Venous heparinized blood was drawn from healthy subjects, immediately aliquoted and adjusted to 5 target blood glucose (BG) ranges for the repeatability and 11 BG concentrations for the linearity tests. For the hematocrit interference test, each sample within 5 target BG ranges was split into 5 aliquots and adjusted to hematocrit levels across the acceptance range. YSI 2300 STAT Plus was used as the laboratory reference method in all experiments. Results: Measurement repeatability or precision was acceptable across the target BG ranges for all devices and strip lots with coefficient of variation (CV) between 3.4-9.7% (mean: 5.7%). Linearity was shown by a correlation coefficient of .991; however, a positive bias was seen for BG <100 mg/dL (86% measurements did not meet ISO15197:2015 acceptance criteria). Significant hematocrit interference (up to 20%) was observed for BG >100 mg/dL (ISO15197:2015 acceptance criteria: ±10%), while the results were acceptable for BG <100 mg/dL. Conclusions: The BGM met repeatability requirements but demonstrated a significant measurement bias in the low BG range. In addition, it failed the ISO15197:2015 criteria for hematocrit interference.

Cyanobacteria are phylum of bacteria that obtain their energy through photosynthesis. They are also known as Cyanophyta. It is known as the most famous transformation model in microorganisms. BG-11 medium which is composed of nine ingredients and carbon sources with specifically combinatorial ratio is used to cultivate cyanobacteria. One approach to improve the growth speed of cyanobacteria in a laboratory setting is to optimize the cultivation medium and tailor the supplements according to the microorganism’s need. A general cultivation medium for S. elongatus PCC7942 named BG-11 had been developed and is a standard prescription. However, many biochemical researchers still want to figure out a new recipe to make a new concentration ratio of ten ingredients to let the cyanobacteria grow faster and efficiently. Nowadays, with the advanced of nano and micro technology techniques, many experiments can be conducted on the small area or chips with a little restriction especially in biochemical or biomedical experiments used the MEMS techniques. In experiments, we would like to know the influence of each ingredient to the growth effect of cyanobacteria, therefore, we used the UV lithography to fabricate the concentration gradient generator (CGG) mold and cultivated gene transfer cyanobacteria pcc7942 in PDMS made chambers by using a high throughput micro channel design. Compared to conventional methods by cultivated manually in large amount of medium in big beakers, we used the microfluidics concentration gradient system to cultivated automatically and only with small amount of medium in biochips. It saves the experimental costs and areas as well. In this chip, we can observe six results detected by absorbance value (Aλ) with different concentration in same ingredient at the same time in 1D chips. Besides, we also add the nutrients such as vitamin and urea to cultivate cyanobacteria to find out whether those exotic nutrients will stimulate the growth of cyanobacteria. Finally, we will show the growth data cultivated by traditional flask methods to certify the similar trend with the cultivation in microfluidics chips.

Abstract:
This study reports a factor 5.5 increase in hydrogen production of Anabaena variabilis ATCC 29413 using Allen-Arnon medium compared with BG-11 and BG-110 media. The results were obtained with a flat panel photobioreactor made of acrylic and operated in two stages at 30°C. Stage 1 aims at converting carbon dioxide into biomass by photosynthesis while Stage 2 aims at producing hydrogen. During Stage 1, the photobioreactor is irradiated with 65 μmol/m2/s of light and sparged with a mixture of air and carbon dioxide. During Stage 2, irradiance is increased to 150 μmol/m2/s and the photobioreactor is sparged with pure argon. The parameters continuously monitored are (1) the cyanobacteria concentration, (2) the pH, (3) the dissolved oxygen concentration, (4) the nitrate and (5) the ammonia concentrations in the medium, and (6) the hydrogen concentration in the effluent gas. The three media BG-11, BG-110, and Allen-Arnon are tested under otherwise similar conditions. The light to biomass energy conversion efficiency varied between 5.5 and 10.5% and was similar for all media. The cyanobacteria concentrations during Stage 2 were 1.10 and 1.17 kg dry cell/m3 with BG-11 and Allen-Arnon media, respectively, while it could not exceed 0.76 kg dry cell/m3 with medium BG-110. The average specific hydrogen production rates were about 1 and 0.9 L/kg dry cell/h in media BG-11 and BG-110, respectively. In contrast, it was about 5.6 L/kg dry cell/h in Allen-Arnon medium. The maximum light to hydrogen energy conversion efficiencies achieved were 0.26%, 0.16%, and 1.32% for BG-11, BG-110, and Allen-Arnon media, respectively. The larger specific hydrogen production rates, efficiencies, and cyanobacteria concentrations achieved using Allen-Arnon medium are attributed to the presence of vanadium, and higher concentrations of molybdenum, magnesium, calcium, sodium, and potassium in the medium.

Abstract:
In 2020, we conducted double spraying soybean plants with growth regulator Proliant, BG containing gibberellin acid at the beginning of flowering and pods formation phases, experiment was done on leached black soil of the central natural-climatic zone of the Krasnodar region. This caused increase of yield by 0.12–0.27 t/hа (4.2–9.5 %) and air-dried biomass by 0.22–0.35 t/hа (5.9–9.4 %), protein yield – by 47.5–108.4 kg/hа (5.0–11.5 %), oil yield – by 21.1–45.1 kg/hа (3.8–8.0 %). Key words: soybean, yield, yield quality, plant growth regulator, leached black soil.
