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,

Nutritional therapy may slow down cirrhosis

One in 400 citizens of western industrialized countries suffers from chronic liver disease or its end-stage, liver cirrhosis. The only definite cure for this is a liver transplant, but the scarcity of organs and required immunosuppression render

An “appealing” small virus

In 1975 in London , an australian researcher, doctor Yvonne Cossart has detected by immunological procedures a new virus in the serum of a blood donor; the name of the blood pocket was B19 so this virus

How plant virus hides from the host cellular degradation machinery

The main goal of obligatory viral parasites is to create the perfect environment for its multiplication. Therefore, the first step is to avoid degradation by the host cellular degradation. Tomato yellow leaf curl virus (TYLCV) is not

The autonomous glycosylation of Giant, but sweet, viruses

The most of proteins carry sugars on them, which significantly modify their properties such as biological activity, solubility and resistance to protein-degrading enzymes. The sugars on proteins drive several fundamental biological mechanisms, such as hormones response, immune

Making a good drug against a bad virus better

Recent advances in the treatment of chronic Hepatitis C virus (HCV) have led to a number of treatment options using only pills taken once-a-day that can lead to the elimination of the virus – a cure. Using

In silico prediction of ebolavirus RNA polymerase inhibition

A virus at work: Let us assume that you are a virus that just infected a cell (the HOST CELL) of an individual (the PATIENT). What is your vicious objective? You want to make copies of yourself

The origin of the HIV-1 epidemic

The epidemic of human immunodeficiency virus type 1 (HIV-1), the causative agent of AIDS, is one of the world’s major public health problems, with around 37 million people currently infected with this virus. The HIV-1 epidemic originated

HCV controls the export machinery of infected cells to increase its own spread

When a virus infects a cell it changes a lot of the cells functions and behavior to its own benefit. The virus reproduces inside the cell and forces it to release many new virus particles which can

Cerium fluoride nanoparticles protect cells against oxidative stress

Nano-biomaterials engineering is one of today’s most promising areas of materials science. In very recent years, nanocrystalline cerium oxide (nanoceria) has been shown to possess enormous biological activity, which originates from its ability to scavenge the reactive

Bibliometric analysis of scientific output on influenza in Mexico, 2000-2012

During the spring of 2009, H1N1 influenza became the first pandemic of the 21st century. In the last years, bibliometrics studies have proliferated seeking to provide data on world research. There are no bibliometric studies in Mexico

Ultrasensitive detection of influenza viruses by glycan biosensors

These days there is a considerable interest to develop devices, which are able to detect various diseases at early-stage with a high speed and reliability to enhance efficiency of subsequent disease treatment. The first step towards this goal

Silencing suppressor proteins shape virus-host co-evolution

Plant viruses are amongst the most important pathogens causing huge economic losses worldwide by reducing crop quality and quantity. A better understanding of the viral infection processes and plant defense strategies is important for crop improvement. During

A novel reovirus mutant: toward the next generation of viruses for cancer treatment?

In the last decade or so, it has been realized that viruses are not only foes to fight, but possible therapeutics against diseases such as cancer. Most of these so-called oncolytic viruses are engineered to acquire desirable

Counteracting a host factor allows adenovirus infection to progress to new virus production

Viruses use the cells of another organism to reproduce and spread. Although very variable in size, the genetic material of a virus is usually tiny in comparison to that of its host and so cannot specify very

Is the post-polio syndrome due to chronic poliovirus infection?

Over the years, poliomyelitis survivors may experience e progressive decline of physical strength accompanied by intolerance to cold, chronic pain and other disabilities. This condition, termed post-polio syndrome (PPS), may lead to the incapacity of living an
