Prevalence of HCMV, HHV‐6, and HSV‐1/2 in the semen of men attending infertility clinics and their association with semen parameters

UroPrecision, EarlyView.
Abstract Background Viral infections have been identified as potential disruptors of male reproductive health. This study aimed to investigate the prevalence of human cytomegalovirus (HCMV), human herpesvirus 6 (HHV‐6), and herpes simplex virus types 1 and 2 (HSV‐1/2) DNA in semen samples from fertile and infertile men within the potential impact of ...

Toxicologic effects of a high dose of thymidine in mice

, 1980
The pharmacologic effects and plasma concentrations produced by the ip administration of high doses of thymidine were determined in CDF 1 mice. Within 15 min after the injection of thymidine at a dose of 4.075 g/kg (between LD0 and LD50), mean arterial ...

Schistosomiasis mansoni: evidence for a milder response in germfree mice

Revista do Instituto de Medicina Tropical de São Paulo, 1987
Germfree (GF and conventional (CV) mice were infected intraperitoneally with GF cercariae of Schistosoma mansoni and kept for six weeks. Twenty four hours before killing, they were injected with [³H]-thymidine.

No gain from pain: Lack of nociceptor activation suggests no adaptation for defence in the evolution of European viper venoms

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Snake venoms show variability in composition at all taxonomic levels, both within and between species, and the selective pressures underlying this variation have long been debated.

Persistence of Thymidine Kinase Activity in Mitochondria of a Thymidine Kinase-Deficient Derivative of Mouse L Cells [PDF]

, 1972
The cell line LM(TK-) Cl 1D, a derivative of mouse L fibroblasts deficient in thymidine kinase (EC 2.7.1.21) that shows very little thymidine kinase activity in extracts of whole cells as compared to the parental line, and that does not incorporate ...

Metabolome Diversity Enhances Resistance of Intertidal Clams to Thermal Stress

Integrative Zoology, EarlyView.
Meretrix species are widely distributed intertidal bivalves in China with significant ecological and economic importance, which are sensitive to thermal stress. Our results showed that thermal environments of clam habitats shaped metabolome diversity, which can enhance the resistance of intertidal clams to thermal stress.

Umbilical Cord Blood–Derived Extracellular Vesicles Enhance Neurovascular Regeneration and Improve Erectile Function in a Mouse Model of Bilateral Cavernous Nerve Injury

Andrology, EarlyView.
ABSTRACT Background Erectile dysfunction (ED) secondary to cavernous nerve injury (CNI), such as that occurring after radical prostatectomy, remains a significant clinical challenge, particularly among patients who do not respond to phosphodiesterase Type 5 inhibitors (PDE5i).

Evidence That the Protein Phosphatase Activity of PTEN Contributes to Embryonic Development and Tumor Suppression

Cancer Science, EarlyView.
Mice expressing only mutant PTEN Y138L, a protein which shows normal suppression of cellular AKT yet lacks protein phosphatase activity, die in utero, and heterozygous mice display a range of tumors. This indicates both the lipid and protein phosphatase activities of PTEN work together for normal tumor suppression and embryonic development.
