Abstract

Necrotizing entercolitis (NEC) is an important neonatal disease with a high mortality rate. Inflammatory mediators, such as mainly platelet-activating factor (PAF), leukotrienes (LT) and tumor necrosis factor play an important role in the genesis of NEC. Diets in omega-3 (n-3) fatty acids appear to have an antiinflammatory effect, which is thought to be due to decreased active prostaglandins and leukotrienes production after incorporation of these fatty acids into cell membrane phospholipids. We investigated the protective effect of fish oil (source of n-3 fatty acids) on hypoxia-induced model of NEC. Young mice were divided into three groups; group 1 mice were fed standard chow (n-3 fatty acids-free), group 2 was fed a chow supplemented by 10% fish oil for 4 weeks. Group 3 mice served as control. We examined the intestinal lesions by light microscopy and measured intestinal tissue PAF and LB4 levels in hypoxia-induced model of NEC. Significantly increased intestinal PAF and LTB4 levels were found in group 1 mice when compared to group 2 and group 3 mice. The histopathology of the intestinal lesions in group 1 animals was characteristic of ischemic injury. In the n-3 fatty acids-supplemented animals these lesions were milder. T...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.

Artificial Intelligence in Cardiac Imaging

Artificial intelligence (ai) techniques are increasingly applied to cardiovascular (cv) medicine in cardiac imaging analysis. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.
