The “luminous” gold nanorod: direct observation of electron transfer

Photoluminescence (PL), in which photon is emitted after the absorption of another photon, has been important for many technologies. The first observation of visible PL of gold dates back to 1969, when Mooradian studied bulk gold and

A reproductive technology to reduce cancer risk

Preimplantation Genetic Diagnosis (PGD) is a type of assisted reproductive technology (ART) allowing individuals/ couples to choose which fertilized embryos, created through in vitro fertilization (IVF), are implanted into a woman’s uterus for further gestation. Since its

Scanning Microwave Microscopy: nanoscale imaging of material electrical properties using microwaves

In 1965 Gordon Moore estimated that the number of components on electronic chips would double every 2 years. This prediction has so far been respected. Today’s microprocessors included in our mobile phones and laptops use transistors on

A novel approach to characterizing the type of three-factorial combined toxicity

We carried out an experiment in which outbred white rats were subjected to repeated injections with water solutions of either one of the toxics (Mn, Ni or Cr salts) in doses isoeffective in respect to the lethal

Omega-3 fatty acids ameliorate age-related hearing loss

We have evaluated the effects of a diet rich in omega-3 fatty acids on age-related hearing loss using a mouse model. These mice present early hearing loss, the symptoms appearing normally at 4 to 6 months of

A key molecule for embryonic bone development is dysregulated in cancer

Bone is an endocrine organ with important biological functions. The skeleton produces hormones, such as FGF23 and osteocalcin, which regulate an extensive list of normal functions. Some of these functions include glucose metabolism, male fertility, blood cell

Does neuropathic pain restrict the cortical plasticity after spinal cord injury?

Many studies in animals and humans have shown that the brain reacts with some reorganization (called neuro-adaptive processes) to the amputation of limbs and following a spinal cord injury that leaves the patients with severe motor and

Fat content surrounding your heart may cause your arrhythmia to recur

Epicardial adipose tissue (EAT) is a metabolically active fat depot surrounding the heart. It is located between the outer wall of myocardium and the visceral pericardium. Its proximity to cardiac structures (i.e. vessels, myocardium) and its shared

Cardiac arrests – a thing of the past?

Over the last 20 years rapid response systems (RRSs) have been introduced in the majority of hospitals around the world. Before they existed, many patients would slowly deteriorate and of those, many would either die or have

Vaccinating pregnant women – a global perspective

The World Health Organization (WHO) influenza vaccine policy recommendations aim to protect vulnerable high-risk groups from severe disease. In a 2012 update of its influenza vaccine position, WHO recommended that countries considering the initiation or expansion of
