Field crickets (family Gryllidae) frequently are used in studies of behavioral genetics, sexual selection, and sexual conflict, but there have been no studies of transcriptomic differences among different tissue types. We evaluated transcriptome variation among testis, accessory gland, and the remaining whole-body preparations from males of the field cricket, Teleogryllus oceanicus. Non-normali...

background: acyclovir (acv), a synthetic purine nucleoside analogue, is known to be toxic to gonads. objective: the current study evaluated cytotoxicity of acv on histopathological changes in testis tissue and serum testosterone and lipid peroxidation concentrations of male rats. materials and methods: animals were divided into five groups. one group served as control and one group served as co...

background: trifluralin is a herbicide and used in agriculture widely. it enters plants through developing roots and stops plant cells from division and elongation (meristemic inhibitor). extensive application of trifluralin to control annual grasses and broadleaf weeds in agriculture, horticulture and horn garden, leads to environmental pollution and its entrance into the food chain could have...

1. The metabolism of [4-14C]pregnenolone in vitro by boar adrenocortical and testis tissue has been studied. 2. Boar testis tissue formed three labelled A16e steroids, 5a-androst1 6-en-3oa-ol, 5a-androst1 6-en-3,B-ol and androsta-4, 16-dien3-one. In adrenal tissue very much smaller yields of the same metabolites were obtained. 3. Both tissues produced labelledprogesterone, androst-4-ene-3,17-di...

Testis tortion in the newborn (especially antenatal testis tortion) is observed very rarely and constitutes 10-12% of childhood testis tortions. In testis tortion, firm and painless testicular tissue is palpated on physical examination. Doppler ultrasonography is a sensitive method in the diagnosis. In cases of neonatal testis tortion, the testis can be saved with appropriate surgical explorati...

Spermatogonial stem cells provide the foundation for continued adult spermatogenesis and their manipulation can facilitate assisted reproductive technologies or the development of transgenic animals. Because the pig is an important agricultural and biomedical research animal, the development of practical application techniques to manipulate the pig Spermatogonial stem cell is needed. The abilit...

Quantum dots are new types of fluorescent materials for biological labeling. As a result, QDs toxicity study is an essential requirement for future clinical applications. Therefore, the cytotoxic CdSe:ZnS quantum dots effects on some organs in mice are presented in this study. In this work, 10, 20 and 40 mg/kg doses of CdSe:ZnS quantum dots were injected to 32 adult male mice. Structural and op...
