Tibetan antelope (Pantholops hodgsoni) are an endemic and endangered species of the Tibetan Plateau. Ex situ conservation may represent an important way to protect Tibetan antelope; however, this process may influence aspects of their behavior. To investigate the ability of these antelopes to adapt to new environments, a study on the vigilance behavior of captive antelope in different seasons was conducted. Using instantaneous scan sampling, focal animal sampling, and all-occurrence recording methods, the vigilance rate and vigilance time of captive male and female Tibetan antelope during cold and warm seasons were recorded and analyzed. Very significant sex differences in vigilance behavior were observed during the warm season, but were not observed in the cold season. Interestingly, vigilance behavior showed seasonal variation as there were significant differences in vigilance time and vigilance rate between cold and warm seasons in both males and females. Specifically, males and females showed more vigilance during the cold than warm season. No interaction between season and sex was found in the vigilance behavior of antelope. Comparing vigilance behavioral characteristic with the Kekexili Tibetan antelope indicated that captive antelope could adapt to a new environment.

In social animals, group dynamics profoundly influence collective behaviours, vital in processes like information sharing and predator vigilance. Disentangling the causes of individual-level variation in social behaviours is crucial for understanding the evolution of sociality. This requires the estimation of the genetic and environmental basis of these behaviours, which is challenging in uncontrolled wild populations.

Schizophrenia is a chronic psychiatric disorder marked by severe disturbances in thought, perception, and behavior. Long-acting injectable (LAI) antipsychotics, such as paliperidone, are widely used to promote sustained remission and ensure medication adherence, especially in patients prone to relapse. However, the COVID-19 pandemic has introduced unique challenges, with studies indicating that infections like COVID-19 may exacerbate psychiatric symptoms through neuroinflammatory pathways.

Objective: This study aimed to analyze the pattern, severity, and outcomes of adverse drug reactions (ADRs) associated with rituximab use reported to a regional pharmacovigilance center in Kerala, India.
Methods: This retrospective study analyzed rituximab-associated ADRs reported from 2017 to 2023. ADRs were assessed using the WHO-UMC criteria for causality and the Modified Hartwig Siegel Scale for severity.

EEG monitoring during anesthesia or for diagnosing sleep disorders is a common standard. Different approaches for measuring the important information of this biosignal are used. The most often and efficient one for entropic parameters is permutation entropy as it can distinguish the vigilance states in the different settings.

Objective: The purpose of this study is to identify variables at the time of clinical presentation which place patients at higher risk for mortality following carotid endarterectomy (CEA) for symptomatic lesions. Further, this study will create a risk score for mortality within two years following CEA for symptomatic stenosis to help tailor future postoperative and long-term management by identifying patients who require heightened vigilance in postoperative care to facilitate survival.
Methods: The Vascular Quality Initiative (VQI) CEA module was queried for procedures performed for symptomatic (within 180 days) carotid bifurcation stenosis.
