Multi-tasking proteins protect sea urchins from multitudes of pathogens
Antibiotic resistance in bacteria is a deadly problem for human health, yet these pathogens arise and persist due to the misuse and over-prescription of the same classes of antibiotics. Wouldn’t it be better if there was a
Oxidized cholesterol makes stronger and stiffer cells, promotes blood vessel formation
Atherosclerotic plaques that clog major arteries lead to heart attack and stroke because of the loss of the local blood supply to the heart or to brain tissues. It is also increasingly recognized today that formation and
Do we really know why cardiac surgery is still affected by substantial inflammatory reaction?
Modern cardiac surgery was born in early fifty’s with the use of the heart lung machine. This machine allowed to bypass the heart and the lung, draining the blood from the right atrium, oxygenating and pumping it
How alkaliphiles produce energy to sustain their life under extremely low concentration of proton
Alkaliphiles are defined as microorganisms with optimum growth pH of above 9 (10-9 mol dm−3 H+ concentration). This means that these microorganisms can grow in environment with one-hundredth times lower proton (H+) concentration than that of neutral
Recent trends in treating kidney stones
Kidney stones are incredibly common in the United States and the prevalence is increasing at a remarkable rate. In the United States, the chance of a man having a kidney stone at some point in his life
MOF for oxoanion pollutant sequestration
The rapid industrial growth over the past century has led to the increasingly critical problem of effluent treatment which is usually discharged into water streams. In this regard the capture of inorganic pollutants from such streams has
What we have done on arsenic issue in last 15 years in Bangladesh (The Millennium Development Goal period 2000-2015)?
Arsenic is well known poisonous chemical component which naturally found in underground from soil, and water. Bangladesh is one of the country where certain area of its ground water has been contaminated with arsenic. Majority of its
More equal sexual arousal between the sheets
The cosmetic and functional results of creating a vagina by use of penile and scrotal skin in male-to-female transsexuals are, in general, satisfactory. One of the goals of creating a vagina is to create tactile and erogenous
Atom tunneling in chemistry
While macroscopic objects from everyday life follow the classical laws of physics, microscopic objects obey the laws of quantum mechanics. These quantum objects, such as light (photons), electrons, and atoms, show characteristics of particles as well as
Statins and diabetes: do the benefits outweigh the risks?
Cardiovascular disease (heart attack and stroke) is the leading cause of death in the United States. Prescription cholesterol-lowering medications have been shown to lower the risks for heart attacks and stroke. In fact, roughly 28% of Americans
Bone resorption around dental implants
Implant supported dental restorations are a very common way to realize fixed or removable dentures nowadays. Implants are placed in the bone and they “glue” to the bone thanks to a biological pathway known as osseointegration. In
Assessment of anxiety: a matter of temperature?
Anxiety is an emotional response occurring when individuals are facing challenging situations or threats. This affective state promotes adaptive coping strategies and is associated with changes involving a variety of different, cross-species conserved, behavioral and physiological responses
Brain-derived neurotrophic factor is a miracle fertilizer for our brain?
Brain-derived neurotrophic factor (BDNF) is sometimes called “miracle grow for the brain” because several studies have reported that BDNF “nourishes neurons like fertilizer.” It is well-known that BDNF protects brain cells and stimulates growth of their dendrites
A rare and insidious brain vessel disorder in children with HIV infection
Over the last decade children who acquire HIV infection from their mothers are surviving longer due to improved access to health care, nutritional support and antiretroviral therapies (ART). As they live longer, complications which were previously not recognised in
In vivo imaging of immunotherapeutic glioma model
Glioblastoma remains one of the deadliest diseases faced by patients, with a median survival of less than 15 months. Therapeutic advancements in the field rely heavily on animal models, and the use of human brain tumor cells
Altered states of consciousness during sex
The term ‘altered states of consciousness’ usually means states of ‘absorption’ or ‘absorbed states’. Some call them trance. They are characterized by loss of the usual sense of self, time, and space, as a result of intense
Computational identification of plastic debris in the marine environment
The presence of plastics on the marine environment has several dangerous effects on the aquatic living organisms. Plastics have high chemical stability and are invariant with respect to the degradation agents. Their accumulation on sea surface produces
Underwater sounds of two marine protected areas in southern Brazilian waters
The collection of sounds that emanate from an environment is known as soundscape in scientific literature. Marine soundscape is based on sounds related to geophony (physical events, such as wind, precipitation, breaking waves, earthquakes), biophony (mammals, fish,
Cancer prevention guidelines are associated with lower cancer risk in low-income and African American populations
Cancer is a major public health burden as an estimated 1,685,210 new cancer cases will be diagnosed in the United States in 2016. In general, African Americans and Americans with low socioeconomic status tend to have higher
