Dry eye syndrome is a complex and insidious pathology with a high level of prevalence among the human population and with a consequently high impact on quality of life and economic cost. Currently, its treatment is symptomatic, mainly based on the control of lubrication and inflammation, with significant limitations. Therefore, the latest research is focused on the development of new biological strategies, with the aim of regenerating affected tissues, or at least restricting the progression of the disease, reducing scar tissue, and maintaining corneal transparency...

BACKGROUND: Isoflavones are natural compounds belonging to the class of isoflavonoids, molecules with a chemical structure based on the 3-phenyl chromen-4-one backbone. As a particular element, the isoflavones are called also phytoestrogens, due to the structural similarity with 17-β estradiol, the primary female sex hormone, presenting both estrogen-agonist and estrogen-antagonist properties. This class of secondary plant metabolites has been extensively reported in the literature for a wide range of therapeutic activities including antioxidant, chemopreventive, anti-inflammatory, anti-allergic, antibacterial, cardio preventive effects...

It has been the dream of many scientists and engineers to realize a non-contact remote sensing system that can perform continuous, accurate and long-term monitoring of human vital signs as we have seen in many Sci-Fi movies. Having an intelligible sensor system that can measure and record key vital signs (such as heart rates and respiration rates) remotely and continuously without touching the patients, for example, can be an invaluable tool for physicians who need to make rapid life-and-death decisions. Such a sensor system can also effectively help physicians and patients making better informed decisions when patients' long-term vital signs data is available...

REVIEW
Jiemin Zhou, Zi-Ao Huang, Ujendra Kumar, David D Y Chen
Lung cancer is the most common cause of cancer deaths, its global incidence is rising, and continuing rises are predicted. The potential to diagnose lung cancers based on the determination of volatile organic compounds (VOCs) in human breath has been attracting increasing attention with the development of new techniques and methodologies. However, despite many reports of VOC profiling in lung cancer patients, little is known about how specific biomarkers relate to the biochemical pathways involved in lung cancer development, and there is still no reliable method for diagnosing lung cancer at the early stages...

Mitral regurgitation (MR) is the one of the most frequent valvular heart diseases in the developed world, often requiring surgical correction. Degenerative MR is the most common type of non-ischemic, organic MR in the western world. Since no medical treatment has been shown to be effective in preventing the consequences of volume overload in asymptomatic degenerative MR, risk stratification is essential. Currently, this is achieved using clinical and precisely quantified echocardiographic parameters, with newer technologies like cardiac magnetic resonance gaining increasing prominence...

Pulmonary vein isolation (PVI) is central to ablation approaches for atrial fibrillation (AF), yet many patients still have arrhythmia recurrence after one or more procedures despite the latest technology for PVI. Ablation of rotational or focal sources for AF, which lie outside the pulmonary veins in many patients, is a practical approach that has been shown to improve success by many groups. Localized sources lie in atrial regions shown mechanistically to sustain AF in optical mapping and clinical studies of human AF, as well as computational and animal studies...

Dual-targeting/Multi-targeting of oncoproteins by a single drug molecule represents an efficient, logical and alternative approach to drug combinations. An increasing interest in this approach is indicated by a steady upsurge in the number of articles on targeting dual/multi proteins published in the last 5 years. Combining different inhibitors that destiny specific single target is the standard treatment for cancer. A new generation of dual or multi-targeting drugs is emerging, where a single chemical entity can act on multiple molecular targets...
