Dormant Mycobacterium tuberculosis: a quiescent form with an eye open
Tuberculosis (TB) is the leading cause of mortality by a single pathogen in humans. Mycobacterium tuberculosis (Mtb), the etiologic agent of TB, causes millions of new cases each year. TB is an ancient disease and Mtb is
Why and how should we screen injured workers?
Every year, tens of millions of workers suffer accidental injuries leading to general practitioner treatments or hospitalizations. Thus, accidents are frequent and many of the survivors are left with temporary or permanent disabilities. Most accident insurers report
Surgical energy in the contaminated wound: too much of a good thing?
Surgical energy has been widely used since its invention in the early 1900. Today, electrosurgery accounts for 80% of all dissections and hemostasis. For surgical energy we commonly refer to the capability of an electrosurgical unit (ESU)
Rodent cochlear nucleus – the common and the uncommon
Our perception of environmental sounds depends on the function of our ears. Sound vibrations received by each of our two ears are converted to electrical signals in the cochlea part of the inner ear. The electrical signals
New generation of recyclable and rigid heat-shrinkable tubes
Heat-shrinkable tubes (HSTs) can shrink back to original sizes when they are heated to shrinkage temperatures (Ts), and they have been widely used in automobiles, electronics, communications, aircrafts, petroleum, aerospace and so on. Traditional HSTs are made
How bacteria swim
Bacteria are the smallest free-living (self-replicating) organisms. Most swim in aqueous media by rotating flagella, long thin filaments driven at their base by rotary motors. In most cases, the filaments are helical and extend out into the
How will China’s development of wind power contribute to global warming?
As a non-fossil technology, wind power has an enormous advantage over coal because of its role in climate change mitigation. Despite wind power may not be a pure zero-emission technology from the perspective of life cycle emissions,
High efficiency OSCs by simultaneous plasmon-optical and -electrical effects from plasmonic asymmetric modes
Organic solar cells (OSCs) have the advantages of low-cost, non-toxic and easy to scale up etc., which are promising to address the energy issues. However, the OSC efficiency is still low to meet the commercialization criteria. The
Producing cellular transport proteins without cells: a key to study novel molecular targets of malaria parasites
Malaria tropica, the most severe and fatal form of malaria, is caused by mosquito-transmitted, single-celled Plasmodium falciparum parasites. More than 3 billion people in 100 countries live in malaria-endangered areas. Every year, > 200 million new infections
Methadone and quality of life: high, low or adjusted doses?
The usefulness of methadone in treating opiate addiction is unquestionable. It is a simple, clean and cheap treatment without any significant side effects. In recent decades, many institutions have written guides and have formulated recommendations advising the
A new three-headed, long-tailed molecular beast eats cancer
We made and tested a series of new compounds containing three chemical rings and hooked them to long carbon tails. These new molecules killed a broad range of pediatric and adult cancer cells including neuroblastoma, osteosarcoma, malignant
Interleukin-18: Critical molecule in promoting allergic diseases
First interleukin was discovered in 1977 from monocyte and termed as interleukin (IL)-1. Interleukins are the secreted proteins that bind to their specific receptors with leukocytes. They are recognized as a family of cytokines based on sequence
How to delete the collimator influence on the gamma camera image: HURRA Filter
In this work we describe an easy method to eliminate the high energy collimator artifacts in the planar image of a gamma camera. A Gamma camera is an instrument widely used in nuclear medicine. This is nothing
Has temporary agency work negative effect on well-being?
Over recent decades many workers have been employed with a temporary agency contract. Little is known about the effect of this status on job conditions and workers’ well-being over time. The current study focused on a sample
Gold-silver nanoparticles instead of traditional diabetic drugs
Recently, we have published a pioneering work on green biosynthesis and complete characterization of gold and core shell silver-gold nanoparticles (AuNPs and Ag@AuNPs) via using green biopolymer in the influence of microwave radiation. These synthesized nanoparticles provide
A natural product derived from fatty acids found in nuts and seeds reduce obesity
Obesity is a major worldwide epidemic. In the US, one third of the population is overweight, another third is obese. There are many complications of obesity, including metabolic syndrome, diabetes, heart disease, fatty liver, high blood pressure,
10th International Conference & Exhibition on Biologics & Biosimilars. San Francisco, California, USA. October 16-17, 2017
BioSimilars 2017, invite you to attend the 10th International Conference and Exhibition on Biologics and Biosimilars in San Francisco, USA. The 10th International Conference and Exhibition on Biologics and Biosimilars will provide an opportunity to hear and
Chloroplast movements after blue light pulses give new insights into the photoreceptor functioning
Plants rely on light as a source of energy. The availability of light is often a limiting factor for the process of photosynthesis. However, too much light can cause cell damage. Plants have numerous mechanisms of adjusting
Biological larviciding against malaria mosquitoes in rural West Africa – A cost analysis
Malaria is still the most common vector borne disease in Africa, although the number of cases and deaths was reduced by 18 and 48% respectively since the 2000s. In 2015 some 188 million people fell sick from
Halogen bonding assembly of an iodide-binding triple helix
Wind turbines, spiral staircases, and springs—these are a few examples of helices in everyday life. The helix is also a reoccurring concept in mythology, spanning many cultures. In biology, helices are both essential and pervasive. Collagen, the
