The well-being of donors undergoing frequent plateletpheresis has been a matter of concern. The aim of this study was to analyze the effect of frequent plateletpheresis on the haematological parameters (HP) of repeat donors. ⋯ Repeated plateletpheresis can be done without any detrimental effects on the cell counts of the plateletpheresis donors. The three cell separators yielded similar post-donation follow up haematological parameters.

Dengue virus (DENV) causes outbreaks and sporadic cases in tropical and subtropical countries. Documenting intricacies of DEN outbreaks is important for future interventions. The objective of this study was to report clinical, laboratory and epidemiological features of DEN outbreaks reported in different districts of Central India in 2016. ⋯ Our study showed that DENV 3 was the major serotype responsible for outbreaks that occurred in monsoon. High attack rates and lower number of secondary infections in rural areas indicated that DENV is emerging in rural parts of Central India. Early diagnosis at local level and timely intervention by mosquito control activities are needed to avoid such outbreaks in future.

The detailed assessment of sperm morphology is important in the semen of infertile men because there is a low proportion of normal spermatozoa. One of the parameters of such sperm morphology is the acrosome, and its effect on assisted reproductive outcomes is controversial. This study was undertaken to evaluate the association between different forms of acrosome on the chromatin status and the assisted reproductive outcomes. ⋯ Our findings showed that the different sperm acrosome morphologies (e.g., large, small, and without acrosome) might negatively relate with chromatin integrity and decrease the sperm's fertility potential and pregnancy rate during intracytoplasmic sperm injection (ICSI) cycles.

Mouse is a preferred animal model for studying pathogenesis of Japanese encephalitis virus (JEV) infections, and different routes of inoculation have been tried. Some neurotropic viruses can reach the brain following infection through ocular route. This study was undertaken to establish JEV-induced clinical disease in mouse model through conjunctival route and document the neuropathological effects. ⋯ JEV infection in mice through conjunctival route produced characteristic clinical signs of the disease and neuropathological lesions. Demonstration of JEV antigen in association with neuropathological lesions in the central nervous system and neuronal cells of the eye showed that conjunctival route could be an effective alternate route for virus invasion into the brain. These findings have biosafety implications for researchers, veterinary practitioners and pig farmers.
