Prevalence of HIV, hepatitis B and C virus infections among candidates for orthopedic trauma surgeries
Infectious diseases are diseases caused by bacteria, virus or fungus micro organism and very readily given by one person to another. These diseases especially those that are transmitted via human blood and cause disease in humans include,
Towards organs on demand: a new platform for successful kidney organogenesis
The ultimate treatment for end-stage renal disease is orthotopic transplantation. However, the demand for kidney transplantation far exceeds the number of available donor organs. While more than 100,000 Americans need a kidney, only 17,000 people receive a
Biocatalysts for hydrogen fuel cell: Biology’s unique way to prevent breakdown by oxygen
Hydrogen could fuel the future! Together with oxygen, hydrogen can be converted to electricity with only water as an exhaust product. The conversion from hydrogen to electricity is done in fuel cells, which require a platinum catalyst.
Direct monitoring of the interaction between ROS and cerium dioxide nanoparticles in living cells
Swallowing the pill we don’t know whether it comes to the target, destroys the harmful objects (microbes, viruses, cancer cells) and/or whether it works correctly at the center of the inflammation. Let’s imagine that each grain of
Allelic variations within genes coding for cytokines among Orang Asli in Peninsular Malaysia: New candidate genes for future disease studies
Cytokines are a set of low molecular weight proteins/glycoproteins secreted by almost all types of cells. They regulate cell growth, immune response and blood cell development in the bone marrow. Genetic variations in cytokine genes include single
Risk factors of hypertension amongst adults in rural areas of South Africa
Cardiovascular disease (CVD) is now the leading cause of death worldwide, and its major impact is not only observed in developed countries but also in developing countries. In 2008, CVD caused 30% of all global deaths, of
Recent advances in gold nanoparticle-based optic sensor
The ease in preparation and conjugation, stability, biocompatibility, as well as the size-dependent optical properties makes gold nanoparticles (Au NPs) one of the most popular nanomaterials for sensing of analytes of interest in the last decade. We
Strong magnets to investigate novel dental implants
Replacing lost natural teeth with dental implants is not a recent technological advancement. The implant history dates back thousands of years and includes the ancient Chinese, Egyptians, Mayans, Celtic and Etruscans civilizations. A variety of attempts and
Making the smallest possible fullerene molecules
It was in 1985 when the soccer ball appeared in chemistry. Spherical carbon cages were discovered, now known as the fullerenes and consisting of 60 carbon atoms in the shape of a soccer ball. Their discoverers have
Aging is adaptive
Aging is a lifecycle stage common to all life forms and is observed in both unicellular and multicellular organisms. The primary manifestation of aging in unicellular organisms is replicative senescence. As the cell ages, cell cycles become
Ex-vivo percutaneous absorption of enrofloxacin
Enrofloxacin is an antibiotic from the fluoroquinolone family used to cure several infections. This antibiotic inhibits DNA replication required for bacterial growth. It is against a wide range of bacteria, including those resistant to other antibiotics. Enrofloxacin
Cerium dioxide nanoparticles increase immunogenicity of the influenza vaccine
Influenza and acute respiratory infections are the viral diseases having tendency for fast epidemic spread. The 2009 “swine flu” pandemic caused by the H1N1 flu virus has revealed the need not only for a detailed study of
Visual side-effects in radiation treatment of meningioma
Meningioma is one of the most prevalent tumors in the brain. This kind of tumor arises from the natural layers covering the brain; so it is expected to see this tumor in different locations of brain. There
Fish gills help understand human lung disease
Persistent inflammation of the lung leads to fibrosis, a serious and poorly understood disease that causes scarring of the lungs. A poor prognosis of only approximately 3 years survival after diagnosis demonstrates the lack of understanding of
From complex questionnaire and interviewing data to intelligent Bayesian Network models
Medical data is very often badly structured, incomplete and inconsistent. This limits our ability to generate useful models for prediction and decision support if we rely purely on machine learning techniques. That means we need to exploit expert
Who is that person? Exploring how the brain organizes information about identity
How do we recognize someone? People can be recognized from many different cues — their face, their walk, their voice, their name, and so on. The sensory or cognitive operations that process these different cues are located
Understanding how enzyme injection for Dupuytren’s disease works
The fascia of the hand is a thin layer of connective tissue that wraps around the muscles, tendons, and neurovascular constitutions in the palm of the hand, providing structural support and integrity. The palmar and digital fascia
Multiple injuries (polytrauma) result in skeletal muscle wasting and insulin resistance
Polytrauma is a combination of injuries that occur over a short period of time (simultaneously or within minutes of each other). These injuries can include burn, fracture, hemorrhage, trauma to the extremities, or penetrating trauma to the
Solar radiation reduces endurance exercise performance in a hot environment
Environmental conditions have a large influence on the development of fatigue during physical activity and exercise . High ambient temperature reduces endurance exercise performance compared with moderate and low ambient temperature . Moreover , in a hot
Select the right atom to adjust atomic motions in transition metal dichalcogenides
Transition Metal Dichalcogenides (TMDs) are materials made from sheets of transition metal cations (Mo, W etc.) sandwiched between two sheets of chalcogen atoms (S, Se, Te); such atomic sandwiches are held together by weak forces (e.g. van
