Quadriceps performance under activation of foot dorsal extension in healthy volunteers
The muscle (m.) quadriceps femoris on the front of the thigh stretches the leg in the knee joint and is the strongest muscle in the human body. It is important in activities of daily living as walking
Withaferin-A, a phytochemical, has potential to reduce liver injury due to acetaminophen overdose
Acetaminophen (APAP), also known as paracetamol, is the most popular over-the-counter drug used for common illnesses such as head and body ache, cold and fever. When administered in therapeutic doses (≤ 4 grams/24 h for an adult),
The matrix reloaded: how a self-produced extracellular matrix controls the development of multicellular microbial communities
In nature, many bacteria live in multicellular communities called biofilms. Biofilms offer their resident bacterial cells protection from environmental insults and assaults, and better attachment to hosts. For humans, they have medical and industrial costs, but also
Age-dependent impairments in spatial learning in mice with reduced BDNF levels
The protein BDNF (brain-derived neurotrophic factor) belongs to the family of nerve growth factors (neurotrophins). Therefore, one of its major functions is related to the maturation and differentiation of developing nerve cells in the brain. But BDNF
The evidence for wheat bran related to obesity, diabetes and cardiovascular disease
Wheat is a leading human cereal crop. Wheat bran (WB) is a by-product of conventional milling of wheat grains and is a concentrated source of dietary fiber. Interest in WB as a source of dietary fiber and
Genetic complexity in Peninsular Malaysia: a great challenge for blood donor recruitment centres
Providing safe blood and blood products (e.g. packed red blood cells, platelets and fresh frozen plasma) are important measurement in the modern era of transfusion practices. Transfusion of blood and blood products from donor to patient requires
Time-saving and life-saving impact of a dedicated childbirth operating room in hospitals in Ghana
Despite global efforts to improve medical care in Sub-Saharan Africa, childbirth remains one of the most dangerous experiences that women and their babies can face. Delays in receiving appropriate emergency care during the crucial moments of childbirth
CKD affects mortality in TAVI patients
Aortic stenosis (AS) is the most frequent type of valvular heart disease in Europe and North America. It primarily presents as calcific AS in old people (2–7% of the population > 65 years). Calcific AS is a
Biodegradable packaging films with improved mechanical and barrier properties
Conventional plastics pose major threat to environment because they are non – biodegradable and are derived from non – renewable resources. Despite this demand for conventional plastics has been rising steadily over the years. It is estimated
Anxiety linked to earlier alcohol involvement
Mental health and substance use disorders are common in the general population and the leading disorders within these are anxiety and alcohol use disorders, with approximately 20 – 30% of the population experiencing one during their lifetime.
Aerobic condition accelerates carotenoid production in Enterococcus gilvus
Lactic acid bacteria (LAB) is industrial important bacteria because LAB are used in fermented foods and probiotics. The clarification of the stress tolerance mechanism of LAB is beneficial for probiotic and molecular breeding to equip LAB with
Distinguish males and females using the mandibular canine tooth
Rao and collaborators developed a methodology based on the mandibular canine to estimate the sex of an individual. Using this methodology, called mandibular canine index (MCI), the authors proposed a cut-value above which the subjects should be
Compounds earlier known as neurotransmitters are met and function in every living organism
Historically, the neurotransmitters function were analyzed only in animals with nervous system, and their initial role was associated mainly with the transmission of nerve (electrical) impulses. In the last decade of the 20 century, new views on
Could the organ shortage ever be met?
A commonly expressed view is that increasing the number of donors will solve the organ shortage and in the UK there has been a 58 per cent increase in deceased organ donations from 2007-8 to 2014-15. The
Optimization of charge carrier transport balance for high efficient polymer solar cells
Polymer solar cells (PSCs) with poly (diketopyrrolopyrrole – terthiophene) (PDPP3T): [6,6] – phenyl – C71 – butyric acid methyl ester (PC71BM) as active layers were fabricated from different temperature solutions. The champion power conversion efficiency (PCE) of
Targeted ion therapy using nanoparticles – a new direction
A living body is made of the smallest building block, called ‘cell’. It gives us a shape, helps us to perform physiological and biological activities, and so on. A eukaryotic cell contains a nucleus, buried in the
Genome sequence of the natural antagonist Pseudomonas fluorescens 2-79 against fungal plant diseases
In agriculture we have to deal with a huge variety of diseases caused by phytopathogenic bacteria, fungi or insects for instance. Many of these plant pathogens live in the soil and attack the respective cultivar at the
B cells to the rescue: regulatory B cells are a promising therapeutic target for autoimmune disease
Immune cells are indispensable for protecting us from microbial infections. They recognize specific patterns on microbes to mount robust cellular and molecular immune responses for the clearance of pathogens. Intriguingly, development and function of these cells is
Ban of asbestos has saved lives
Banning of the use of asbestos in Sweden has two components. In the mid-1970s the use was restricted through an agreement between unions and employers in the construction industry and there was also a voluntary restriction in
Grow TiO2 nano-crystals on cellulose to sequester lead in water
Heavy metals in water pose significant threat to environment and public health. Lead, for example, when present above the action level in drinking water as a toxin, can cause a variety of adverse health effects such as
