In this study, growth and osmolyte concentration in the leaves of halophyte, Sesuvium portulacastrum, were studied with respect to salinity. Therefore, the changes in shoot growth, leaf tissue water content, osmolyte concentration (proline content, glycine betaine) and antioxidant enzymes [polyphenol oxidase (PPO), superoxide dismutase (SOD) and catalase (CAT)] were investigated. The 30-day old S. portulacastrum plants were subjected to 100, 200, 300, 400, 500 and 600 mM NaCl for 28 days. The plant growth was steadily increased up to 500 mM NaCl stress at 28 days. TWC was higher in 300 mM NaCl treated leaves than that of 600 mM NaCl. Salinity stress induced the accumulation of osmolyte concentration when compared to control during the study period. The antioxidant enzymes PPO, CAT and SOD were increased under salinity.

Human endogenous retrovirus-K (HERV-K) is the most recently integrated retrovirus in the human genome, with implications for multiple disorders, including cancer. Although typically transcriptionally silenced in normal adult cells, dysregulation of HERV-K (HML-2) elements has been observed in cancer, including breast, germ cell tumors, pancreatic, melanoma, and brain cancer. While multiple methods of carcinogenesis have been proposed, here we discuss the role of HERV-K (HML-2) in the promotion and maintenance of the stem-cell in cancer. Aberrant expression of HERV-K has been shown to promote expression of stem cell markers and promote dedifferentiation. In this review, we discuss HERV-K (HML-2) as a potential therapeutic target based on evidence that some tumors depend on the expression of its proteins for survival.

The novel coronavirus SARS-CoV-2 was discovered in 2019 and has proven to be a significant public health challenge. While viruses from the coronavirus family have been established as causes of respiratory tract infections, SARS-CoV-2 has also been found in the heart, kidney, testes, and penis. This paper investigates whether SARS-CoV-2 can linger in the prostate by examining the histopathological, ultrastructural, and immunofluorescent elements of prostatic tissue from a patient who was infected by the SARS-CoV-2 virus prior to having a holmium laser enucleation of the prostate (HoLEP) procedure. The findings of this case report suggest that COVID-19 has both the ability to enter prostatic tissue during an acute infection and persist over a timeframe beyond the initial infection period as RNA-containing viral bodies. This case report lays the foundation for future investigations to examine any histopathological changes to the prostatic tissue that may be associated with SARS-CoV-2 viral infection.
