There are many messages about nanomaterials. There are the both bad and good facts. It is clear these substances are fastly penetrate into many fields of everyday life, such as food, cosmetics, pharmaceutics, electronics, etc. Therefore one
Some need to reduce blood pressure medication in hot weather
Many people take medication for blood pressure control. But there have been many reports suggesting (i) that dosage should be reduced in hot weather and (ii) a need for long-term individual studies. This paper presents a case
Metallic iron for environmental remediation: ending a myth
Iron corrosion is widely known as a destructive process. However, several useful applications of this process are known. Three examples are: consumption of humidity in food packaging, H2S removal from biogas and water treatment. Water treatment by
Cell division drives collective motion in cell monolayers
Cell division is essential to morphogenesis, tissue spreading, and tumor invasion. In particular, the hallmark of tumor invasion is the ability of cancerous cells to divide in extreme numbers. Our findings on the effect of cell division
Obesity causes lung dysfunction and breathing troubles by increased cysteinyl leukotrienes pathway
Increased body weight is a chronic health problem which has emanated from the globalized food market and dietary habit. This has led to the different types of ailments which occur in obese individual simultaneously and referred to
A functional defect of unconventional suppressor T-lymphocytes might lead to disease progression in lupus autoimmune patients
A healthy immune system discriminates between pathogenic invaders that have to be eliminated, and the body’s own tissues that have to be protected. Central to this role are immune cells called lymphocytes. B-lymphocytes are particularly important, because
Resveratrol is a potential remedy for the treatment of pancreatic fibrosis
The pancreas serves as both endocrine and exocrine glands in a human body in order to help food digestion and blood glucose regulation. In fact, more than 90% of the pancreatic mass comprises the exocrine cells which
Depression and dementia among American Indian and Alaska native elders
In the United States when talking about health care we tend to refer to national or state programs as uniform programs that are accessed by all U.S. citizens. . But there are groups that have a separate,
A potentially lethal condition that may occur in psychiatric patients
Antipsychotic drugs are commonly prescribed in patients with various psychiatric illnesses (e.g. psychosis, schizophrenia, aggressive behavior, etc.). A neurological emergency may arise characterized by muscle rigidity and damage, increased body temperature and cardio-respiratory system instability in patients
The first medical school in America
The founders of first American medical school in Philadelphia, John Morgan and William Shippen, Jr, had received a fine medical education at the University of Edinburgh. As students, they discussed the need for such training in the
High-throughput, motility-based sorting of microswimmers for gene discovery
Organisms’ motility varies with genotype, disease progression, drug treatment, aging, and environmental conditions and can serve as a useful metric to access drug effectuality, to identify drug resistant strains, and, more generally, various genotypes. In 1974, Sidney
Why do older people get so much kidney disease?
To celebrate Sir William Osler’s 70th Birthday on July 12th 1919 his pupils and co-workers contributed scientific articles that were collected and published. One of these articles, by William Councilman pathologist-in-chief at Peter Bent Brigham Hospital, noted

Neurocysticercosis: a mayor public health problem
Neurocysticercosis (NCC) is the most frequent parasitic disease of the central nervous system, and it occurs when the larvae of the tapeworm Taenia solium infects the central nervous system. This disease is endemic in most developing countries
Awful knee pain, rounding up the unusual suspects
If you have had persisting severe knee pain following an arthroscopy you might wonder why. When this happens many people will have a repeated MRI following the surgery despite the fact that one was done before the
Health benefits of haskap: Possible control of inflammation-mediated chronic disorders

What is injured: motor neuron or motor nerve?
All movements, whether simple or very complex (ballet dancing, playing the piano, speaking) are the results of the complex interaction between nerve cells (neurons) from different departments of the brain. But the final arbiters of movement patterns
New biomimetic materials for muscle regeneration
Skeletal muscle formation derives from a coordinated sequence of molecular and cellular changes, ultimately leading to the expression of large, multinucleated contractile fibers, characterized by a highly ordered assembly of striated myofibrils. To form contractile fibers, developing
