This study aims to evaluate the effects of the action of doxycycline on spermatogenesis to provide a complete analysis of the tubular and interstitial compartments and to identify possible changes in the testicular parenchyma. Adult male Wistar rats were divided into three groups: one control (water), and two treated with doxycycline at the doses of 10mg/kg and 30mg/kg, for 30 days. After euthanasia and sample processing, the following parameters were evaluated: a) tubular diameter and height of the seminiferous epithelium; b) volumetric proportions (%) and volumes (mL) of the components of the testicular parenchyma; c) counting testicular germ cell populations; d) evaluation of cell viability. The results of the comparative evaluation between the experimental groups demonstrated a significant increase in the diameter and area of the tubular lumen and a reduction in the count of spermatogonia in the experimental group that received doxycycline hyclate at a dose of 30mg/kg. In the same experimental group, an increase in the overall yield of spermatogenesis was found as a consequence of the increase in the mitotic index.","PeriodicalId":8951,"journal":{"name":"Bioscience Journal","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43438430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Silage points were evaluated at harvest when the grain milk line was at ¾ and maize grains at the maturation stage (dry plant). The 1P2224 and 1Q2383 maize genotypes present silage (high green and dry biomass) and grain yield potential. The GT Biplot tool identified the 1P2224 genotype as superior and suitable for cultivation or as a parent in a breeding program in the midwest region of Brazil for silage and grain yield evaluations of one off-season under limited water and frost.","PeriodicalId":8951,"journal":{"name":"Bioscience Journal","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46168048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The different molecular techniques involve the evaluation of many individuals; therefore, it is crucial to have fast, efficient, and inexpensive methods for DNA extraction.

In the SP environment, 19 genotypes were resistant, 22 genotypes were moderate, and nine genotypes were susceptible, respectively.

Derivatives of ezetimibe reduce inflammatory response and oxidative stress. In the present study, we investigated the effect of dietary supplementation with ezetimibe in response to environmental stressors and found that ezetimibe increases resistance to oxidative stress and ultraviolet irradiation. Ezetimibe also significantly extended lifespan accompanying reduced fertility, which is a common trade-off for longevity in C. elegans. Cellular level of reactive oxygen species was increased and the expression of stress-responsive genes, hsp-16.2 and sod-3, was induced by dietary supplementation with ezetimibe, suggesting a hormetic effect on oxidative stress response and lifespan. Ezetimibe also significantly prevented amyloid beta-induced toxicity and completely reversed increased mortality by high-glucose diet. Nuclear localization of DAF-16 required for the prevention of amyloid beta-induced toxicity was enhanced by ezetimibe supplementation. Lifespan assay using known long-lived mutants, age-1, clk-1, and eat-2, revealed that lifespan extension by ezetimibe specifically overlapped with that of eat-2 mutants, which are genetic models of dietary restriction. Effect of ezetimibe on lifespan of worms fed with diluted bacteria suggested that ezetimibe mimics the effect of dietary restriction on lifespan. These findings suggest that ezetimibe exhibits anti-oxidative and anti-aging effects through hormesis and works as a dietary-restriction mimetic on lifespan extension.","PeriodicalId":8951,"journal":{"name":"Bioscience Journal","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41747386","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eleven morphoagronomic descriptors allowed estimating the diversity among accessions. The measurements of genetic dissimilarity enabled us to observe the genetic distance between the studied materials, standing out the accessions T1.M3 and T2.S4 as the most divergent (446.01). The morphoagronomic descriptors percentage of leaves and stem diameter were the most efficient for estimating the diversity between access. Genetic variability points to the adaptation of Macroptilium accessions in the climate change scenario.
