Published: May 2021

The study titled ‘Occupational aspiration of undergraduate agricultural students of Kerala Agricultural University- A multidimensional analysis’ was undertaken during 2017 - 19. The objectives of the study was to study and compare the occupational aspirations of the male and female undergraduate students of agriculture and also to categorise and compare the male and female undergraduate agricultural students based on the level of occupational aspiration. The study analyses both idealistic and realistic occupational aspirations of the undergraduate agricultural students by considering the concept of long and short range for goal period expression. The study also categorises the students based on their level of occupational aspiration by following the procedure adopted by National Opinion Research Centre (NORC) and Ajit [1] in developing level of aspiration scale. The occupational prestige rating scale establishes level of occupational prestige as viewed in India as well as determines the weighted score for each of the occupation. The sample of the study comprised of 120 third year and final year students i.e., 60 students from College of Agriculture (COA), Vellayani, 35 students from College of Horticulture (COH), Vellanikkara and 25 students from College of Agriculture (COAP), Padannakkad were selected based on proportionate random sampling method. The results on occupational aspiration of the students revealed that more than half (56.65%) of the undergraduate students in agriculture belonged to the category of high level of occupational aspiration. Getting the state/ central government job (67.5%) and entering into administrative sector jobs through PSC’s (48.3%) were the realistic occupational aspirations of majority of the students. Becoming Agricultural scientist in central/ state government (45.85%) and cracking civil services (36.66%) were the idealistic occupational aspirations of the majority of the students. It was also observed that irrespective of the gender and college of study, the students’ level of occupational aspirations remained same.

Experiments were conducted during rabi season of 2019 and 2020 at the Department of Agronomy, Madras Veterinary College, Chennai to assess the performance of fodder maize (Zea mays L.) under varying combinations of organic manures and inorganic fertilizers. An experiment was laid out in split plot design with four organic treatments in main-plots viz., No manure, farm yard manure (25 t/ha), vermicompost (12 t/ ha), poultry manure (12 t /ha) and four fertilizer treatments in subplots with levels of No fertilizer, 125% RDF, 100% RDF, 75% RDF. Recommended dose of fertilizer (RDF) for fodder maize crop is 60 kg N ha-1: 40 kg P2O5 ha-1: 20 kg K2O ha-1. The organic manures were applied as per the N equivalent basis to inorganic nutrient recommendation. The results revealed that all the maize growth parameters, green and dry fodder yield were significantly affected with the application of organic manures and fertilizer levels. Growth parameters viz., taller plants, more number of leaves per plant, higher leaf area index, stem girth, leaf stem ratio were observed under the combined application of poultry manure @ 12 t/ha and fertilizer level of 75% RDF. The highest green matter yield and dry fodder yield were recorded with the integrated application of poultry manure @ 12 t/ ha along with the fertilizer level of 75 % RDF.

Aim: The experiment is aimed at quantifying the nitrogen requirement and identifying suitable hybrids and varieties of castor to be grown during post monsoon season on Alfisols in Telangana
Study Design: Split plot design.
Place and Duration of Study: Regional Agricultural Research Station, Professor Jayashankar Telangana State Agricultural University, Palem, Telangana state, India during post monsoon season of 2010-11 and 2011-12.
Methodology: The study consisted of four N levels (0, 40, 80 kg and 120 kg N ha-1) in main plots and five cultivars (DCH-177, PCH-111, GCH-4, Haritha and 48-1)in sub plots. The growth parameters, yield attributes, seed yield, water use efficiency, economic returns, correlation and regression were studied.
Results: The pooled data indicated that significantly taller plants with more no. of branchesplant-1, longer and effective spikes thus seed yield of castor were observed due to application of 80 kg Nha-1 and 120 kg Nha-1. However, application of 120 kg N ha-1 resulted in greater net returns (USD 1049 ha-1) and also returns per rupee invested (1.66). The results further showed that the castor hybrids PCH-111 (1900 kg/ha) and DCH-177 (1809 kg/ha) produced similar yield, but, both significantly outyielded over other cultivars. The performance of hybrids was superior to the varieties. A highly significant positive correlation was observed for seed yield with no. of branches/plant, total and effective spike length.
Conclusion: The cultivation of castor hybrids either PCH-111 or DCH-177 under N supply of 120 kg N ha-1 would help to realize higher yields, water use efficiency and income from post monsoon season castor on Alfisols.

Aims: Assess The sustainable production of tomato and cucumber under greenhouse conditions for meeting the challenges of natural resources shortage, food security and economic.
Study Design: Two experiments performed in complete randomized blocks with three replicates.
Place and Duration of Study: Central Laboratory for Agriculture Climate (CLAC), Agriculture Research Center, Egypt, during two autumn seasons of 2018 and 2019 (tomato) and two spring seasons of 2019 and 2020 (cucumber).
Methodology: Different soilless culture systems for producing tomato and cucumber under greenhouse were investigated: Hydroponic systems (Nutrient film technique (NFT) and deep flow technique (DFT)); and substrate systems (Dutch bucket, pot, container, and horizontal bag). Vegetative characteristics, yield parameters, N, P, and K contents, and environmental impact assessment were measured.
Results: Substrate systems gave the highest vegetative growth characteristics, yield parameters, N, P and K contents of tomato and cucumber leaves, as well as the highest power use efficiencies compared to hydroponic systems. Container and bags systems gave the highest results of tomato and cucumber vegetative growth, respectively, but the highest yield and net profits records belonged to bags and pots respectively. Bags substrate system gave the highest net profit yield (10.1Kg/ plant and 21881 LE / greenhouse) of tomato plant under plastic house followed by container system that presented the highest yield (10.6 Kg/ plant) but the total cost mainly substrate cost contributed to reduce its net profit yield. While for the highest yield and net profit of cucumber, the pots system (8.1Kg/ plant and 13243 LE / greenhouse) followed container system (7.65Kg/ plant and 9045 LE / greenhouse) and bags system (7.15Kg/ plant and 10270 LE / greenhouse) were recommended. The lowest yield, the highest average power use, cost and efficiency and lowest total cost were estimated by NFT system in both of tomato and cucumber investigations.
Conclusion: The substrate systems presented more sustainability for tomato and cucumber production under plastichouse conditions. Bags substrate system gave the highest net profit yield of tomato plant under plastic house followed by container system that presented the highest yield but the total cost mainly substrate cost contributed to reduce its net profit yield. While for the highest yield and net profit of cucumber, the pots system followed container system and bags system were recommended. The lowest yield, the highest average power use, cost and efficiency and lowest total cost were estimated by NFT system in both of tomato and cucumber investigations.

The SARS-CoV2 virus, the causative agent for COVID-19 disease has to lead to more than 3.1 million deaths and crossed 146 million infections worldwide so far. Although vaccines development and emergency authorization has been approved by several governments, there has been great concern about its side effects for the long term and its effectiveness against new mutated strains. A resurgence of COVID-19 or related disease can be catastrophic. There is an urgent need to look for effective antiviral agents for many coronavirus strains with minimum side-effects, and maximum efficacy globally. Several, naturally-derived biomolecules have proved their excellent effect on several infectious diseases in a multi-mode fashion by targeting several pathways as well as increasing efficacy with high safety profile. Integrate computational prediction design was used in the study to examine the pharmacology of bioactive compounds of natural origin against SARS-CoV2 spike protein. Keeping these facts we have computationally examined 16 naturally occurring compounds using to evaluate their effectiveness against the SARS-CoV2 virus using the molecular docking technique. Hesperidin derivatives are known to ameliorate diabetes, co-morbidity for coronavirus, as well as help in preventing post coronavirus complications. We found the binding free energy of Hesperidin with spike protein to be -7.57 kcal/mol, the aglycone derivative to be -6.93 kcal/mol, hesperidin monoacetyl derivative to be -7.82 kcal/mol, and hesperidin pentaacetyl derivative to be -8.39 kcal/mol. Our findings revealed that acetylated derivatives of hesperidin showed significant improved remarked binding affinity while aglycone derivative hesperetin showed a decrease in binding affinity. Our studies give a new direction where natural bioactive compounds and their derivatives can be modulated and used after clinical trials to effectively inhibit coronavirus infection as well as diabetes simultaneously with a high safety profile.

Introduction: Overactive bladder (OAB), defined as urinary urgency, usually accompanied by frequency and nocturia, with or without urgency urinary incontinence, in the absence of urinary tract infection or other obvious pathology.
Methods: A retrospective review of patients getting intradetrusor onabotulinumA injections for OAB and NDO over a 6-year time frame was conducted. The principal outcome measures involved patient’s subjective improvements in OAB and NDO symptoms and the duration of symptomatic relief following every treatment. The secondary results measured relation of patient’s age and duration of each effective treatment cycle.
Results: One hundred and thirty-Eight (138) consecutive patients who met the inclusion criteria were included in the study. The average age of women was 59.43 years. Eighty four (61%) of participants were still receiving botox injections while 54 women stopped treatment. The average time period between botulinum A injection and its efficacy in controlling OAB symptoms varied from 3 -8.5 months. There was no decrease in efficacy of the treatment with more cycles of treatment. The average age of women who received one, two, three and four or more cycles were 61.7, 53.87, 63.03, and 56.75 years respectively, which showed with advanced age efficacy of botulinum toxin does not decrease.
Conclusions: Our results suggest that in patients who respond to intradetrusor botulinumA treatment, the duration of response does not decline with more treatment cycles, suggesting it as a safe long term treatment option for controlling OAB symptoms. Also there is no relation between advanced age and subsequent efficacy of botulinum A intradetrusor injections.
Lithium Directs Embryonic Stem Cell Differentiation Into Hemangioblast‐Like Cells

Published: May 2021

AbstractDefinitive hematopoietic stem cells (HSCs) derive from specialized regions of the endothelium known as the hemogenic endothelium (HE) during embryonic developmental processes. This knowledge opens up new possibilities for designing new strategies to obtain HSCs in vitro from pluripotent stem cells (PSCs). Previous advances in this field show that the Wnt/β‐catenin signaling pathway plays a crucial role in PSC‐derived HSC formation. In this work, lithium, a GSK3 inhibitor, is identified as an element capable of stabilizing β‐catenin and inducing embryonic stem cells (ESCs) differentiation in hemangioblast‐like cells, highly consistent with the role of Wnt agonists on ESC differentiation. ESCs treated with 10 mm lithium express CD31+, SCA‐1+, Nkx2‐5+, CD34+, and FLK1+ cells characteristic of the hemangioblast cells that precede HE development. However, 10 mm Li treated cells remain arrested in a hemangioblast‐like phase, which switched into the expression of HE markers after stimulation with maturation medium. The ability of lithium‐treated ESCs to further derive into HE is confirmed after defined maturation, resulting in a rapid increase in cells positive for the HE markers RUNX1 and SOX17. The results represent a novel strategy for generating HSC precursors in vitro as a multipotent source of stem cells for blood disease therapies.

AbstractRapid diagnostic testing at the site of the patient is essential when a fully equipped laboratory is not accessible. To maximize the impact of this approach, low‐cost, disposable tests that require minimal user‐interference and external equipment are desired. Fluid transport by capillary wicking removes the need for bulky ancillary equipment to actuate and control fluid flow. Nevertheless, current microfluidic paper‐based analytical devices based on this principle struggle with the implementation of multistep diagnostic protocols because of fabrication‐related issues. Here, 3D‐printed microfluidic devices are demonstrated in a proof‐of‐concept enzyme‐linked immunosorbent assay in which a multistep assay timeline is completed by precisely engineering capillary wetting within printed porous bodies. 3D printing provides a scalable route to low‐cost microfluidic devices and obviates the assembly of discrete components. The resulting rapid and seamless transition between digital data and physical objects allows for rapid design iterations, and opens up perspectives on distributed manufacturing.

Published: May 2021

AbstractResearch on organic thin films is largely driven by potential (opto‐)electronic applications and turns out to be no less intriguing from a fundamental point of view. Numerous studies make it clear that the understanding of device‐relevant molecular thin film architectures is quite challenging—often hampered by insufficient spectroscopic data and the lack of a consistent interpretation of the available datasets. Consequently, speculative aspects prevail in the discussion of energy levels in conjunction with the optical properties of organic thin films. Adequate spectroscopic techniques applicable to thin films of organic molecules (typical thicknesses required for devices are in the nanometer range) with the necessary sensitivities are rather demanding. Some of those methods were developed or significantly improved in the recent past. Here, the now available complementary spectroscopies are briefly surveyed with particular emphasis on some techniques that have not yet become widespread standards, and a non‐exhaustive set of examples of acquired experimental results are provided. For a consistent interpretation of the latter, the concepts brought forward in the literature considering the role of initial and final states of spectroscopic processes are outlined, with important consequences for quantitatively correct energy diagrams.
Reversible and Irreversible Thermochromism in Copper‐Based Halide Perovskites

Published: May 2021

AbstractCopper‐based layered perovskites have shown abundant phase transitions and thermochromic behaviors. However, there are very few cases of perovskites with irreversible transitions. Here, the thermochromic behavior of two perovskites (CEA)2CuCl4 and (BEA)2CuCl4 is discussed, where CEA = 2‐chloroethylammonium and BEA = 2‐bromoethylammonium, the latter of which is reported for the first time. These materials exhibit a reversible and irreversible thermochromic behavior determined by the nature of the organic cation. Using nuclear magnetic resonance, X‐ray diffraction, and optical absorption, it was possible to investigate the mechanism for this transition: a topochemical exchange reaction between the organic and inorganic halides in (BEA)2CuCl4 to yield the mixed‐halide perovskite (BEA)1.1(CEA)0.9CuCl3.1Br0.9. These materials and the fundamental principles shown herein have potential use as low‐cost irreversible thermochromic sensors and their design.

AbstractPotato (Solanum tuberosum L.) is a cool weather crop and one of the most important vegetables in the world, which is cultivated in temperate, subtropical, and tropical climates. Nearly all cultivated areas in Brazil use cultivars from temperate countries, resulting in lower performances particularly due to higher temperatures. The aim of this study was to identify clones that yielded better than foreign cultivars, both under high and mild temperature conditions. The study assessed 57 clones from the potato breeding program of the Universidade Federal de Lavras (UFLA), Brazil, and five check cultivars (Agata, Asterix, Atlantic, Cupido, and Markies). We evaluated the agronomic performance using the total and marketable tuber yield, dry matter content (DM), season length, and external tuber quality, in four experiments designing in a random complete block, during the seasons 2014 and 2015. The genotypes' stability, as well as the discrimination between environments, was performed using the GGE‐Biplot method. Twenty heat‐tolerant clones responded favorably to mild temperatures. This breeding program has generated clones more productive and better looking than commercial cultivars, for the different market segments: two for the fresh market (GMR 17‐40; GMR 12‐10), four for frozen French fries (CBM 07‐78; CTB 03‐02; GMR 15‐42; SR2 35‐05) and seven for potato chips (CBM 16‐16; SR1 07‐16; GMR 03‐58; SR3 19‐24; SR2 57‐02; SR1 04‐06; SR3 32‐04).

AbstractThe goal of this study was to investigate the medical, communication, activities of daily living (ADLs), and mental health concerns affecting adolescents and adults with SATB2‐associated syndrome (SAS). A comprehensive questionnaire was administered to the caregivers of 49 individuals 12 years or older with SAS (mean age was 19.4 years, range 12–37 years). For all individuals, medical records, including laboratory results, were reviewed. Most individuals required some degree of assistance for ADLs and none of the adults were able to live independently. Health status was qualified as excellent or very good in 61% of individuals. The most common medical problems were dental anomalies, with a significantly higher frequency of hypotonia and gastroesophageal reflux in younger individuals. Medical and surgical interventions were often required. Sixty‐nine percent (n = 33) of individuals spoke 10 or fewer words. Autism (41%), anxiety (37%), and attention deficit disorder (37%) were common with one third of individuals receiving medical treatments for these diagnoses. While medical and developmental problems in individuals with SAS were similar to those previously reported, many of these are persistent into adolescence and adulthood. This study provides better guidance for the challenges facing adults with SAS and their families.

AbstractTailored ruthenium sandwich complexes bearing photoresponsive arene ligands can efficiently promote azide–thioalkyne cycloaddition (RuAtAC) when irradiated with UV light. The reactions can be performed in a bioorthogonal manner in aqueous mixtures containing biological components. The strategy can also be applied for the selective modification of biopolymers, such as DNA or peptides. Importantly, this ruthenium‐based technology and the standard copper‐catalyzed azide–alkyne cycloaddition (CuAAC) proved to be compatible and mutually orthogonal.
