The rapid emergence of antibiotic resistance is a worldwide crisis, endangering the efficacy of antibiotic treatment. A recent article in Scientific America (December 16, 2014) highlights the importance of developing strategies for reducing antibiotic resistance and prolonging
Your DNA goes places you have never been: What does this mean for forensic scientists interpreting DNA found at a crime scene?
During a criminal investigation, items are commonly examined for DNA to try to identify a potential suspect (Fig. 1). But is this DNA really from someone involved in the crime or has it got there through innocent
Memory is the first brain function that starts to fade away when Alzheimer disease (AD) pathology affects the brain of a patient. Decline of additional cognitive functions, shortly follows. This progressive and irreversible disease, intrudes the life
Biosafety is a major concern in biotechnology when genetically modified (GM) organisms are used in a process. With increasing interest for cyanobacterial biotechnology and synthetic biology, it is astonishing that there has been, up to now, no
Alzheimer’s disease (AD) is the most common cause of dementia, leading to an enormous burden on societies worldwide. In brains of patients with AD, abnormal tangles of a protein called tau are found within nerve cells, in
Cellulose nanofibrils (NFCs) are the elementary reinforcing constituents of plant cell walls. They are isolated from cellulose fibers in the form of slender semi-crystalline nanofibers (Fig. 1) with outstanding intrinsic mechanical properties, e.g. a longitudinal elastic modulus
100.000 times a day – this is the daily number of heart beats in human beings. This huge workload normally will pass by unobserved in a healthy being, but in a patient with heart disease any alteration
There is an intense drive in the present scenario towards the efficient generation and storage of energy for carrying out the various power driven mechanics of life. The energy demand for development and sustenance of the world
The oldest old, defined as 90 years and over, is the fastest growing segment of the population worldwide. Dementia is one of the major health challenges at this age, since the risk of dementia increases steadily with
Stranded animals provide an exclusive opportunity to investigate the health and conservation status of free-ranging cetaceans across the globe. Based upon the scientific literature hitherto available on this topic, cetacean strandings frequently have a multifactorial aetiology, with
Familiarity with different foods is one factor that has been proposed to explain childhood eating behaviours such as picky/fussy eating and the rejection of uncommon or novel food stuffs. Some research has suggested that this rejection of
86⁰F, hot or warm? 65⁰F, cool or cold? 100 mL glass contains 30 mL of water, empty or full? Same tricky questions in daily life happen in engineering world as well. The Boolean logic of either being
Scientists at British American Tobacco and MatTek Corporation used a unique combination of tests to investigate the potential adverse effects of e-cigarette vapour on airway tissue compared with cigarette smoke. ‘By employing a combination of a smoking
Can metal-exposure induce innate immune reactivity in brain cells and thus contribute to neurotoxicity?
Use of metals in dentistry is quite common for braces, crowns, fillings, implants. Problems sometimes occur, such as allergy, locally inflamed mucosae, or vague symptoms throughout the entire body. However, alternatives such as methacrylates will never completely
Brucellosis, tuberculosis and caprine arthritis-encephalitis, are goats and sheep in El Salvador affected?
Brucellosis and tuberculosis are two animal diseases that occur in Salvadoran cattle and humans may get infected by drinking raw milk. When herds get infected for the first time with brucellosis, massive abortions in the last third
In recent years approval has been granted to many therapeutic agents for the treatment of patients with metastatic melanoma. They include small molecule inhibitors, such as the selective inhibitors of the mutant BRAF (BRAF-I) or of MEK (MEK-I), and
