Abstract:

Studying of characteristics of the Lake Onega ice regime and investigating of the climate inﬂuence on the formation and destruction of the ice cover requires a continuous chronological series of data on the Lake ice coverage. Ice cover is the percentage of the ice area to the total area of the lake. In 1955–1990, calculations of the ice coverage of the Lake were based on the use of the results of airborne ice reconnaissance. On average for this period, from 5 to 15 values were annually obtained, which was not enough for a comprehensive analysis of the ice coverage variability. In this paper, f

Abstract:

This essay examines the theme of blindness in the Gospel of Mark. The two main questions asked are: 1) “What is Mark’s view on blindness?” and 2) “How does the Gospel of Mark’s view on blindness inform the current discourse of disability studies and how can we interpret Mark’s view on blindness today?” By the methods of metaphor analysis and character analysis, four passages of the Gospel are studied (Mark 4:10-12; 8:14-21; 22-26; 10:46-52). The analysis concludes that blindness is depicted by the author of the Gospel as a disability which also consist of a lack of cognitive ability and a hope

Abstract:

AbstractEven after a decade of use, CAR-T cell therapy for non-Hodgkin lymphoma (NHL) is still evolving, and disease control is now the main concern in the majority of experienced centres. Indeed, despite highly appealing objective response (OR) rates in refractory patients, the long-term overall survival (OS) of this population has only slightly improved. Pivotal studies have suggested that 2-year OS rates do not surpass 30%, even though results improve when complete response (CR) is achieved within the first 3 months after treatment (Wang et al. 2020; Schuster et al. 2019; Neelapu et al. 2017). Although achieving this exceptionally high level of OR is praiseworthy, similar improvements have not been made regarding OS, and current OS probabilities are not satisfactory. Of course, there are multiple reasons for this; a substantial proportion of patients either do not achieve an initial response or experience progression very soon after treatment, with poor OS (Chow et al. 2019). Both populations present with disease burden or aggressive cancer prior to CAR-T cell therapy, possibly having been referred too late in the course of treatment or waited too long before CAR-T cells were processed for them. Both of these issues have potential solutions, such as more widely publicizing the efficacy of CAR-T cells, which may increase referrals at an earlier stage, and developing methods, which are already being heavily investigated, for shortening the manufacturing process (Rafiq et al. 2020). In the latter case, the use of allogeneic lymphocytes could allow for already prepared cells to be readily used when needed and would most likely be the most efficient strategy as long as the risk of graft-versus host disease is offset (Graham and Jozwik 2018). Thus, achieving CR is a crucial step in increasing OS, as patients with partial response (PR) or stable disease (SD) present with lower OS, while currently, recurrence appears to be rare when CR is maintained for more than 6 months (Komanduri 2021). However, the disease will likely recur in more than half of patients in the months following treatment, possibly due to issues such as the poor persistence of CAR-T cells (which may not be as crucial as once thought for acute lymphoblastic leukaemia (Komanduri 2021)) or the loss of target antigen expression (which has been regularly documented (Rafiq et al. 2020)). Both of these mechanisms could potentially be used to develop methods that reduce recurrence after CAR-T cell therapy. In fact, the most popular approaches currently being investigated are attempting to either use two CAR-T cell types that each target different antigens or to create CAR-T cell constructs that target either multiple antigens or an antigen other than CD19 (Shah et al. 2020). The concomitant infusion of CAR-T cells with targeted therapies is also being explored in other B-cell malignancies and appears to both increase the CR rate and decrease recurrence (Gauthier et al. 2020). When recurrence does occur, patient OS is rather dismal, and the best remaining option would most likely be inclusion in a clinical trial. If this option is not available, salvage therapy may be attempted, although cytotoxic treatments are extremely limited given that most diseases have been refractory to numerous lines of treatment prior to immunotherapy. A few case reports and studies with a small patient population receiving anti-PD-1 antibodies, ibrutinib, or ImiDs have been reported with largely anecdotal supporting evidence (Byrne et al. 2019). However, even in the case of a new objective response (OR), the subsequent risk of recurrence is substantial and may invite further consolidation with allogeneic haematopoietic stem cell transplantation (Byrne et al. 2019), which has already been performed in patients treated for acute lymphoblastic leukaemia (Hay et al. 2019). However, the efficacy of this strategy remains to be validated in NHL patients in clinical trials. Further supporting evidence, although limited, has recently been reported concerning an additional treatment with CAR-T cells inducing an OR. Of the 21 NHL patients included in the study, the OR rate after the second infusion was 52% (CR, n = 4; PR, n = 7), with some durable responses inviting further investigations (Gauthier et al. 2021). Overall, with such poor outcomes after recurrence, current efforts are also focused on predicting the patients most likely to experience disease progression and that are potential candidates for preemptive consolidation therapy, although there is no doubt that patients who do not achieve a rapid CR should be the first candidates. Additionally, immune monitoring should encompass not only CAR-T cell survival but also the detection of circulating tumour DNA (Komanduri 2021) because this could aid in detecting subclinical recurrence and in deciding whether consolidation or maintenance therapy should be administered. However, currently, all these approaches are highly speculative and require further clinical study.

Neera, Sumana. "Chemical Fertilizer Medium on Tissue Culture of Strawberries." In Strawberries [Working Title]. IntechOpen, 2022. http://dx.doi.org/10.5772/intechopen.104741.

Full text

Abstract:

The strawberry is a nutrient-rich fruit with high concentrations of vitamins A, C, B1, B2, protein, calcium, potassium, copper, iron, and especially antioxidants. Strawberries are an extremely popular fruit because the antioxidants in them are much more than in tomatoes, up to 7 times. Strawberry propagation now requires a tissue culture-derived cultivar. Infection from the mother plant causes low yield due to diseases, and the chemicals utilized as bait in vitro are expensive. The purpose of this experiment was to find a replacement for the chemical fertilizer mix that was affecting the strawberry’s in vitro growth. The experiment was conducted with the strawberry cultivar Royal 80 and the 5 × 4 Factorial in CRD. Explants were cultivated in media containing five types of chemical fertilizer: 21-21-21 (N-P2O5-K2O), 15-30-15 (N-P2O5-K2O), 36-5-5 (N-P2O5-K2O), 15-30-15 (N-P2O5-K2O) and 10-52-17 (N-P2O5-K2O) at concentrations of 0.5, 1.5, 2.5 and 3.5 g L−1, compared to MS medium, which provided control for each type of fertilizer. The plantlets were cultured in 0.5 g/l of 21-21-21 showed the highest number of plantlets was 4.30 plantlets/explant, which was better than MS medium (3.44 plantlets/explant), 15-30-15 and 36-5-5 media (3.48, 3.87 plantlets/explant, respectively).

Abstract:

En route to (+)-varitriol 4, Xue-Wei Liu of Nanyang Technological University coupled (Org. Lett. 2011, 13, 42) the glycosyl fluoride derived from 1 with the alkynyl fluoroborate salt 2 to give 3. James S. Panek of Boston University condensed (Org. Lett. 2011, 13, 502) the enantiomerically pure allyl silane 6 with the aldehyde 5 to give the tetrahydrofuran 7. Further elaboration led to (+)-isatisine A 8, the only alkaloid so far isolated from the roots and leaves of the traditional Asian folk medicine Isatis indigotica. Arun K. Ghosh of Purdue University effected (Org. Lett. 2011, 13, 66) oxidative ring expansion of the enantiomerically pure furan 9 to give, after reduction, the enone 10. This established the tetrahydropyran of (+)-herboxidiene 11, also known as GEXIA. William J. Chain of the University of Hawaii observed (J. Am. Chem. Soc. 2011, 133, 6553) unusual diastereoselectivity in the conjugate addition of the enone 12 to the enantiomerically pure aldehyde 13. Although eight diastereomers could have been formed, the reaction mixture was 2/3 the diastereomer 14. Reductive cyclization (SmI2) of 14 then led to (–)-englerin A 15. Martin J. Lear of the National University of Singapore cyclized (Org. Lett. 2010, 12, 5510) the enantiomerically pure lactol 16 to 17 with catalytic Bi(OTf)3. Dennis L. Wright of the University of Connecticut prepared (Org. Lett. 2011, 13, 2263) 21 by dipolar cycloaddition of 20 to 19. Both 17 and 21 were carried on via intramolecular alkylation toward platensimycin 18.

Abstract:

David Milstein at the Weizmann Institute of Science reported (Angew. Chem. Int. Ed. 2013, 52, 6269) the unusual deamination of amine 1 to alcohol 3 catalyzed by ruthenium complex 2. In the reverse sense, Qing Xu at Wenzhou University found (Adv. Synth. Cat. 2013, 355, 73) that the conversion of benzyl alcohol (4) to sulfonamide 5 was catalyzed by benzaldehyde and catalytic potassium carbonate. Gold(I) catalysis was utilized (Chem. Commun. 2013, 49, 4262) by Ai-Lan Lee at Heriot-Watt University for the direct etherification of allylic alcohol 6 with isopropanol to produce 7. Tobias Ritter at Harvard demonstrated (J. Am. Chem. Soc. 2013, 135, 2470) that the reagent PhenoFluor (9) developed in his laboratory displays astonishing selectivity for the late-stage deoxyfluorination of complex alcohols and polyols, including glucopyranoside 8 to produce 10. A Mitsunobu protocol for the conversion of alcohol 11 to ester 13 using catalytic amounts of the hydrazide 12 and iron(II) phthalocyanine was developed (Angew. Chem. Int. Ed. 2013, 52, 4613) by Tsuyoshi Taniguchi at Kanazawa University. We reported (Org. Lett. 2013, 15, 38) a Mitsunobu-like inversion of alcohol 14 to mesylate 16 catalyzed by diphenylcyclopropenone 15. Domingo Gomez Pardo and Janine Cossy at ESPCI Paris Tech found (Org. Lett. 2013, 15, 902) that the reagent XtalFluor-E (18) was effective for the coupling of N-Boc proline (17) and phenylglycine ethyl ester (19) without epimerization to furnish the dipeptide 20. The conversion of primary amide 21 to secondary amide 23 via cross-coupling with boronic acid 22 was reported (Org. Lett. 2013, 15, 2314) by Donald A. Watson at the University of Delaware. Catalysis of the Lossen rearrangement of hydroxamide 24 to carbamate 26 using N-methylimidazole (25), which helped to minimize side products, was reported (Org. Lett. 2013, 15, 602) by Scott J. Miller at Yale University. Keiji Maruoka at Kyoto University demonstrated (Angew. Chem. Int. Ed. 2013, 52, 5532) that propionaldehyde (27) could be converted under simple conditions to N-Boc aminal 28, which served as a convenient source for the in situ generation of the corresponding highly useful N-Boc imine.

Abstract:

The increased demand for high strength linepipe for onshore and offshore pipeline systems has been well documented over the past few years. The economic benefits have been demonstrated, and solutions have been developed to address the technical issues facing high strength linepipe use. However, there are still a few unanswered questions, one of which is addressed in this paper: what is the effect of thermal treatment during the pipeline coating process on the material behaviour of high strength linepipe? This paper presents the results of a thermal coupon study investigating the effects of low

Abstract The energy available for a sailing ship is a combination of wind energy and the energy in the water. The wind energy propels the ship blowing into the sail and in this way generates the thrust. The energy in the water can be transformed into electrical energy by means of a hydrokinetic turbine. The electrical energy can be stored in a battery or it can be converted into hydrogen by means of an electrolyzer. In such a combination the ship is called an energy ship. In this work a new extended design method for the hydrokinetic turbine of the energy ship is presented and three different
