Neuroinflammation is known to be a contributing factor for several neurological disorders as well as cognitive dysfunction. Different signalling pathways, and a variety of supporting cells of CNS are suggested to be involved in the progression of neurodegeneration. Among the factors contributing to neuroinflammation, peripheral inflammation takes a lead role according to recent research, since persistent peripheral inflammation is believed to disrupt the blood-brain barrier (BBB).

Background And Aim: Bacterial lipopolysaccharide (LPS)-induced neuroinflammation can be the most dependable animal model for studying neurodegeneration mechanisms driven by systemic inflammation-induced neuroinflammation. Hence, this study aimed to standardize the LPS model of neuroinflammation by comparing the effect of relatively low-dose LPS administered for different durations on the induction of neurodegeneration in Wistar rats.

Materials And Methods: Six groups of six adult Wistar rats per group were used in the study.

Background And Aim: Depression and anxiety are the most prominent neuropsychiatric disease and have been considered as the most burdensome diseases of society. The hippocampus and prefrontal cortex have a prominent role in stress-induced neurological disorders. Chronic unpredictable stress exposed rats are a perfect model in understanding comorbid depression and anxiety disorders.

Introduction: Radiation is an important tool in the diagnostic and curative treatment of many cancers. Ionizing radiation induces many biochemical changes in the cells. The present study was designed to estimate the level of neurotransmitters in the distinct brain tissue of Swiss albino mice before exposing gamma radiation.

Introduction: Anthropometry is a simple reliable method for quantifying body proportions by measuring body length, weight and circumferences.

Aim: Our intention in this study was to compare sensitivities and positive predictive values of waist circumference (WC), waist-hip ratio (WHR), waist-height ratio (WHtR) and body mass index (BMI) in identifying healthy subjects, males and females separately for identifying obesity associated dyslipidemia.

Materials And Methods: We analysed randomly selected 100 healthy subjects (males:58%, females:42%) between 25 and 60 years of age attending tertiary health care center in South India, after obtaining informed consent and Institutional Ethical Clearance.
