Background: Reperfusion syndrome after carotid endarterectomy is a complication associated with cerebrovascular self-regulation in a chronically hypoperfused cerebral hemisphere, leading to severe neurological damage. Vitamin C is an important antioxidant in brain metabolism that has shown some neuroprotective actions.

Objective: To investigate the potential effects of vitamin C on cerebral reperfusion in comparison with placebo (saline) in rats.

Methods: Male Wistar rats were divided into 3 groups: (i) Sham ( = 4), animals exposed to carotid arteries dissection without clamping; (ii) Control ( = 4), animals exposed to carotid arteries dissection without clamping; (ii) Control ( = 4), animals exposed to carotid arteries dissection without clamping; (ii) Control (.

Results: Rats treated with vitamin C presented with a similar behavior as compared to the Sham group in all the three tests ( > 0.05), but it was significantly different from controls ( > 0.05), but it was significantly different from controls ( > 0.05), but it was significantly different from controls (.

Conclusion: In the present study, vitamin C was associated with behavioral and motor preservation as well as decreased cerebral MDA levels after induced cerebral ischemia in rats.

Background: Preimplantation embryos in vivo are exposed to various growth factors in the female reproductive tract that are absent in in vitro embryo culture media. Cell-free fat extract exerts antioxidant, anti-ageing, and ovarian function-promoting effects. However, its effects on embryo quality are yet to be investigated.

Background: The detection of multiple bluetongue virus serotypes, increasing trend in livestock density, rich biological diversity with high endemism, and the status of the Andaman and Nicobar Islands as a popular tourist destination underscore the need for a faunistic survey of medically and veterinary significant vector species, specifically Culicoides, in this region. Moreover, scattered information on Indian Culicoides species complicates the planning and implementation of preventive measures for pathogens transmitted by these vectors. This study aims to provide the first comprehensive account of the Culicoides fauna in the Andaman and Nicobar Islands, India, along with an updated checklist of Indian Culicoides species and their state-wise distribution.

The epitope of the antibody used in the REAADS VWF activity assay is quaternary.

The REAADS VWF activity assay is often assumed to be specific for the A1 domain, the portion of VWF that binds platelet GPIbα. We tested this assay on the A1A2A3 region of VWF with each domain expressed independently of one another and together in combination as a tri-domain. The monoclonal antibody used in this assay is found to be insensitive to the single A domains and does not recognize free A1 domains as it is often assumed.

Perfluorinated compounds (PFAS) are well recognized toxic pollutants for humans, but if their effect is equally harmful for healthy and fragile people is unknown. Addressing this question represents a need for ensuring global health and wellbeing to all individuals in a world facing the progressive increase of aging and aging related diseases. This study aimed to evaluate the impact of perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA) and perfluorohexanoic acid (PFHxA) exposure on development and skeletal phenotype using the osteogenesis imperfecta (OI) zebrafish model Chihuahua (Chi/+), carrying a dominant glycine substitution in the α1 chain of collagen I and their wild-type (WT) littermates.

Vaccination stands as one of the most sustainable and promising strategies to control infectious diseases in animal production. Nevertheless, the causes for antibody response variation among individuals are poorly understood. The animal microbiota has been shown to be involved in the correct development and function of the host immunity, including the antibody response.
