Genome-wide DNA methylation in an animal model and human studies of schizophrenia: a protocol for a meta-analysis.

Introduction And Objective: Neuropsychiatric disorders like schizophrenia are heterogeneous in that they occur because of the interaction of factors. These factors include but are not limited to genetic, epigenetic, neurobiological and environmental factors. Methylation of DNA, like other erpigenetic modifications, is risk factors for neuropsychiatric disorders.

Association of microalbuminuria with serum lipids and inflammatory markers in an adult population in the Dikgale Health and Demographic Surveillance System site, South Africa.

Background: There is evidence that microalbuminuria (urinary albumin excretion) is an early sign of vascular damage and an established risk factor for cardiovascular morbidity and mortality. This study investigated the magnitude of microalbuminuria and its association with serum lipids and inflammatory markers among a rural black population residing in the Dikgale Health and Demographic Surveillance System site, South Africa.

Methods: Data were collected from 602 presumably healthy participants (225 men and 377 women) aged ≥ 18 years.

Physiological Genomics Plays a Crucial Role in Response to Stressful Life Events, the Development of Aggressive Behaviours, and Post-Traumatic Stress Disorder (PTSD).

Physiological genomics plays a crucial role in responding to stressful life events, such as violence and traumatic stress. This exposure to traumatic stress can trigger several physiological pathways, which are associated with genetic variability. Exposure to traumatic stress can result in the development of behavioural and psychiatric disorders, such as aggressive behaviour and anxiety disorders.

Effectiveness of Double-Hit Model (Post-Weaning Social Isolation and NMDA Receptor Antagonist) in the Development of Schizophrenic like Symptoms on Rodents: A Protocol for a Systematic Review.

Background: Schizophrenia is a heterogeneous neuropsychiatric disorder, categorized by positive, negative, and cognitive symptoms. In trying to improve the diagnosis and treatment of schizophrenia, researchers have turned to "dual hit" models of schizophrenia that are able to reproduce all symptoms of the disorder. The main objective of this protocol is to present a transparent process on how we plan to review the existing international literature on the effectiveness of "dual hit" models used to induce schizophrenia on rodents.

Early Life Stress and Brain Plasticity: From Alterations of Brain Morphology to Development of Psychopathology.

Advances in our understanding of the genetics of mental disorders (MD) have contributed to a better understanding of their pathophysiology. Nonetheless, several questions and doubts remain. Recent research has focused on the role of the environment in developing mental disorders, and the advent of neuroscientific methodologies has opened up new avenues of inquiry.

DNA Methylation and Schizophrenia: Current Literature and Future Perspective.

Schizophrenia is a neuropsychiatric disorder characterized by dissociation of thoughts, idea, identity, and emotions. It has no central pathophysiological mechanism and precise diagnostic markers. Despite its high heritability, there are also environmental factors implicated in the development of schizophrenia.

A pilot study: Relationship between Bisphenol A, Bisphenol A glucuronide and sex steroid hormone levels in cord blood in A South African population.

Exposure to Bisphenol A (BPA) during early development particularly in- utero has been linked to a wide range of pathology. The aim of this study was to examine the relationship of BPA and its naturally occurring metabolite BPA-glucuronide (BPA-g) with sex steroid hormone levels in South African mother-child pairs. Third-trimester serum maternal samples and matching cord blood samples were analyzed for BPA, BPA-g and nine sex steroid hormones using liquid chromatography tandem mass spectrometry (LC-MS/MS).

Reducing sample rejection in Durban, South Africa.

Objectives: Rejections of clinical chemistry specimens delays the availability of results, which may impact patient management. The study aims to measure sample rejection rate, identify reasons for sample rejection, evaluate the effect of a campaign to reduce rejection rates and discover which clinical units produced the most insufficient specimen.

Methods: The study measured specimen rejection rates and the contributions of different rejection reasons in calendar 2016 and April 2018-March 2019.

A pilot study: Bisphenol-A and Bisphenol-A glucuronide levels in mother and child pairs in a South African population.

Unlabelled: Exposure to Bisphenol A (BPA) during early development particularly in- utero has been linked to a wide range of pathology. The aim of this study was to determine serum levels of BPA and its naturally occurring metabolite BPA-glucuronide (BPA-g) in South African mother-child pairs.

Method: Third-trimester serum maternal samples and matching cord blood samples were analysed for BPA and BPA-g using LC-MS/MS.
