Acute Treatment with Fucoidan Ameliorates Traumatic Brain Injury-Induced Neurological Damages and Memory Deficits in Rats: Role of BBB Integrity, Microglial Activity, Neuroinflammation, and Oxidative Stress.

There is no acquiesced remedy for the treatment of traumatic brain injury (TBI)-associated impairment, especially cognitive decline. The first 24 h after TBI is a golden time for preventing the progress of the impairments. The present study aimed to examine the acute effects of fucoidan on neurological outcomes and memory performance and investigate its potential mechanisms in rats with TBI.

Differentiation of Enteric Nervous System Lineages from Human Pluripotent Stem Cells.

The human enteric nervous system, ENS, is a large network of glial and neuronal cell types with remarkable neurotransmitter diversity. The ENS controls bowel motility, enzyme secretion, and nutrient absorption and interacts with the immune system and the gut microbiome. Consequently, developmental and acquired defects of the ENS are responsible for many human diseases and may contribute to symptoms of Parkinson's disease.

Patterning and folding of intestinal villi by active mesenchymal dewetting.

Tissue folds are structural motifs critical to organ function. In the intestine, bending of a flat epithelium into a periodic pattern of folds gives rise to villi, finger-like protrusions that enable nutrient absorption. However, the molecular and mechanical processes driving villus morphogenesis remain unclear.

Patterning and folding of intestinal villi by active mesenchymal dewetting.

Tissue folding generates structural motifs critical to organ function. In the intestine, bending of a flat epithelium into a periodic pattern of folds gives rise to villi, the numerous finger-like protrusions that are essential for nutrient absorption. However, the molecular and mechanical mechanisms driving the initiation and morphogenesis of villi remain a matter of debate.

Health service delivery models for elderly people: A systematic review.

Current Health care delivery systems are not effective for the elderly. Countries with high elderly populations are expected to design special models to serve their elderly population. The aim of this study is to investigate the models of health care delivery to the elderly in different countries.

Androgen Signaling Regulates SARS-CoV-2 Receptor Levels and Is Associated with Severe COVID-19 Symptoms in Men.

SARS-CoV-2 infection has led to a global health crisis, and yet our understanding of the disease and potential treatment options remains limited. The infection occurs through binding of the virus with angiotensin converting enzyme 2 (ACE2) on the cell membrane. Here, we established a screening strategy to identify drugs that reduce ACE2 levels in human embryonic stem cell (hESC)-derived cardiac cells and lung organoids.

Androgen Regulates SARS-CoV-2 Receptor Levels and Is Associated with Severe COVID-19 Symptoms in Men.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has led to a global health crisis, and yet our understanding of the disease pathophysiology and potential treatment options remains limited. SARS-CoV-2 infection occurs through binding and internalization of the viral spike protein to angiotensin converting enzyme 2 (ACE2) on the host cell membrane. Lethal complications are caused by damage and failure of vital organs that express high levels of ACE2, including the lungs, the heart and the kidneys.

Challenges of implementation: Strategic purchasing in Iran Health Insurance Organization.

Background: Strategic purchasing has been introduced as a key strategy for solving the problems faced by insurance companies. In Iran, the government has mandated the Iran Health Insurance Organization (IHIO) to implement this strategy. However, there are serious challenges to achieving that.

Urban family physician plan in Iran: challenges of implementation in Kerman.

Background: The Family Physician Plan has recently been implemented in three provinces of Iran on a pilot basis and is going to be implemented throughout Iran in the future. Through a qualitative design, this study aims to determine probable implementation challenges of Family Physician Plan in Kerman.

Methods: This study was conducted in Kerman in 2013.

Evaluation of plasma MMP-8, MMP-9 and TIMP-1 identifies candidate cardiometabolic risk marker in metabolic syndrome: results from double-blinded nested case-control study.

Aims: Matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) are dysregulated in metabolic syndrome (MetS) and associated with atherosclerosis and cardiovascular disease (CVD). Previous studies on the association between MMPs/TIMPs and MetS are controversial. We aimed to evaluate circulating MMP-8, MMP-9 and TIMP-1 in a group of MetS individuals and healthy controls to find the potential marker associated with MetS and its components.
