In this experiment we studied the influence of chemical fertilizers on physiological indices and the amount of protein in two soybean varieties, Atlas and Hodgson. Researches has been carried out between 2017-2019 at Didactic Station of BUASMV Timişoara with different doses of chemical fertilizers. Observations and measurements were made on plant physiology and yield characteristics. The process of accumulation of dry substances in different organs of the plant during the vegetation period is dependent to the effectiveness of fertilization. The dynamics of the total water content in the plant and especially its modification under the influence of chemical fertilizers is of interest for the appreciation of the process of formation of dry substances, respectively of agricultural harvest. In both varieties between the experimental and the control variant, significant differences appeared in all followed indicators, the most favorable variant being N45P63K45. Superior results were registered at Atlas, better adapted to the ecological conditions of the reference area. Fertilizers are decisive factors in the increase of yield and the quantity of protein, although this plant has the capacity to supply some of the necessary nitrogen with bacterial symbionts. High doses of phosphorus did not produce higher yields compared to moderate ones.

Background: The urd bean variety MDU 1 has a duration of 70-75 days, bushy in nature and is susceptible to yellow mosaic virus. In order to develop a determinate type and improved batter quality, MDU 1 and VBN (Bg) 4 blackgram seeds were treated with different doses (100 Gy, 200 Gy, 300 Gy, 400 Gy and 500 Gy) of gamma rays. Methods: Uniform sized seeds treated with different mutagenic doses were raised in randomised block design which constitute M1 generation. Each plant was harvested individually and forwarded to M2 generation following plant to progeny row method. The determinate types were selected from M2 generation and forwarded to further generations. After attaining homozygosity in the advanced generation, the mutants were checked for its biochemical characters (Total solubule protein content analysed by kjeldahl method, albumin and globulin analysed by Lowery’s method, arabinose content analysed by Bial method. Result: The mutants ACM - 16 -011, ACM - 16 -015, ACM - 16 -018 were found to have an arabinose content of 8.28%, 8.98% and 8.14% respectively. All these mutants recorded more batter volume over the variety MDU 1. The albumin (%) and globulin (%) contents were also found at remarkably increased levels in the mutants. These mutants have the potential to develop a high quality variety of urd bean and therefore are very useful in breeding programme.

The small intestinal villus is covered with a thick layer of mucus that is secreted by goblet cells and functions primarily to first barrier from damage by toxic substance. Recent studies showed that goblet cells and mucins involved in complex immune function. Lipopolysaccharide (LPS) is widespread in the housing of livestock, which can induce bacterial infection symptoms and immunological stress within a short of time. Therefore, we aimed to study the effects of long-term exposure to different doses of LPS on intestinal mucus layer and immune barrier. The result showed that mucus layer thickness and goblet cell functions were significantly increased after low doses of LPS. The intestinal mucosal barrier can block the bacteria of the lumen, but LPS can penetrate this barrier into the blood, putting the body in a state of chronic low-grade inflammation and reducing the body&rsquo;s immune function. However, after long-term exposure to high doses of LPS, a large number of lysosomes in goblet cells caused loss of function, and mucus layer thickness was significantly decreased. A large amount of LPS stuck to the mucus, leading to normal LPS and inflammatory cytokines level of plasma. The intestinal tissue morphology was damaged, and a number of immune cells were necrosis in the intestine. Collectively, long-term exposure to low doses of LPS lead to chronic low-grade inflammation in the body. Long-term exposure to high doses of LPS can be directly linked to the severity of the immunosuppression in the body.

Abstract Background and objective: As an oral hypoglycemic drug that significantly reduces cardiovascular risk, empagliflozin is used in patients with type 2 diabetes. However, the dosage and administration of empagliflozin are still controversial clinically. To determine the appropriate treatment, we performed this network meta-analysis.Methods: We identified randomized controlled trials (RCTs) about empagliflozin from databases including PubMed, Ovid MEDLINE, Embase, ScienceDirect, Web of Science, the Cochrane Library, Scopus and Google Scholar. We analyzed the pharmacodynamics, adverse effects (AEs), and pharmacokinetics of empagliflozin at different doses.Results: We identified 8264 articles, of which 26 RCTs with 11796 patients were included. Regarding hemoglobin A1c (HbA1c ) and fasting plasma glucose (FPG), high doses (10, 25, 50 mg) were significantly better than low doses (1, 2.5, 5 mg). For total AEs, there was a dose-response trend in which safety decreased with increasing doses. According to SUCRA sequencing, the order for lowering HbA1c was 25 > 50 > 10 > 2.5 > 5 > 1 mg, for lowering FPG was 50 > 25 > 10 > 5 > 2.5 > 1 mg and for safety was 1 > 2.5 > 5 > 25 > 10 > 50 mg. When considering HbA1c, FPG and total AEs, we performed a hierarchical cluster analysis and network meta-analysis to find that 25 mg performed best among different doses, which was more significant after long-term use (≥ 12 weeks). Pharmacokinetic parameters exhibited significant dose-response relationships .Conclusions: High doses (10, 25, 50 mg) had better efficacy than low doses (1, 2.5, 5 mg). When considering HbA1c, FPG and total AEs, 25 mg performed best among the different doses. More RCTs exploring unconventional doses are needed to confirm these conclusions.

Seed of pigeonpea variety Kaki were irradiated at Oak Ridge National Laboratories with different doses of gamma rays and neutrons. The effects of both sources of radiation were studied on seed germination, plant growth, and flowering date during the X1 generation, and plant height and number of days to flower on the X2 generation. The results indicate that both sources of radiation reduced seed germination, and plant height, and induced both earliness and lateness in number of days to flower during the X1 generation. Genetic variability for plant height and early- and late-flowering lines was increased considerably in the X2 generation in the radiated population. With the new source of germ plasm located it appears that pigeonpea varieties can now be selected with more desirable characteristics, thus permitting a considerable increase in production in Puerto Rico.
