The heart consists of 4 chambers in mammals. The upper two chambers are atria, and the lower ones are ventricles. Ventricles work as pump to eject blood to whole body. Atria have 2 important roles: 1) to
A better way to measure heart disease risk for an overweight society

Do ready meals provide adequate nutritional value for the elderly?
The UK is the biggest market for ready meals in Europe, and the single elderly rely more on ready meals than any other group in British society. But do these meals provide adequate nutritional value? A recent
β-Carotene requirement for anti-aging depends on genetic background
Cellular telomere, a region of repetitive nucleotide sequences of TTAGGG, resides on both ends of chromosomes and its length is shortened by reflecting the replication number of chromosomal DNA, accordingly, telomere length is the most reliable indicator
Caste-ethnic disparity in vaccine use among children in Nepal
The United Nations’ Millennium Development Goal 4 addresses child mortality as a major indicator of health and development, revealing much about a nation’s health services and related social and economic factors. Currently, an estimated 8.1 million children
Can eradication of a bacterium in the stomach increase the platelet count in patients with chronic ITP?
Platelets are blood cells that play a major role in causing blood clots to form and preventing excessive bleeding so their reduction or dysfunction can result in bleeding and even death. These cells are made in the
Why is atmospheric mercury level decreasing even thought the emissions are increasing?
Mercury is a unique metal that is a liquid at room temperature, which enables it volatile to the air and diffuse ubiquitous at a global scale. It becomes an environmental problem because the consumption of mercury-containing food,
Fine tuning of inflammation is a key to successful limb regeneration
Complete regeneration of appendages after amputation in certain fish and amphibians has long served as a useful model for analyzing why regeneration is unsuccessful in most mammalian organs. Recent work with zebrafish, frog tadpoles, salamanders, reviewed in
Aberrantly methylated DNA regions in IgA Nephropathy patients affect the disease
The genome can influence the onset and the development of the diseases in several manner, and in the last years several studies have revealed the new role of the DNA methylation in this framework. The DNA methylation
Sex traffickers target girls with intellectual disabilities
It is well known that children with intellectual disabilities face a much higher risk for sexual abuse and sexual assault than those without disabilities. Perpetrators of child sexual abuse select victims who have disabilities because they view
Atomic classification of cancer cells
Cancer cells have molecules, known as receptors, on their surface that distinguish them from healthy cells. Knowing receptors that are present on malignant cells can help to detect and/or classify the disease. Here, we developed a method
Self-reference effect on memory and well-being in patients at risk for Alzheimer’s disease
In cognitive psychology, the term self-reference effect (SRE) refers to the fact that individuals remember information better when the latter are related to themselves. This effect particularly boosts episodic memory, that is, the detailed memory of personal

Genetic information of mosquito blood cells decoded
Mosquitoes are most dangerous tiny animal killing 7.25 million peoples in the world annually, as they transmit many deadliest pathogens causing malaria, dengue, chikungunya, zika virus infection etc. Despite of the strong innate and adaptive immune system
Habituation of involuntary conscious processes
New research is beginning to reveal that, though action inclinations can be suppressed behaviorally, they often cannot be suppressed mentally (see Passive Frame Theory). Consider that, when presented with an enticing stimulus such as a cupcake, one
Benefits of aging?
Does pain increase or decrease with age, and if so, what causes the change? A factor we considered is that sensitivity to pain could be altered by an age-related loss of neurons involved in regulation of affective/emotional
Atomic wires of carbon: present status and perspectives
Carbon is all around us in different forms ranging from molecules to solids, minerals and nanostructures. Organic chemistry classifies alkanes, alkenes and alkynes hydrocarbons according to the different hybridization state of carbon atoms (sp3, sp2 and sp1,
Assessing the outcome of multiple trauma patients based on their GCS and FOUR score coma scale
Evaluating the level of consciousness is one of the initial, important and basic assessments of patients and it can be challenging even for experienced physicians. Various scoring systems have been defined that can be helpful in predicting
