Skin is the outermost covering of the human body and at the same time the largest organ comprising 15% of body weight and 2 m(2) surface area. Skin plays a key role as a barrier against the outer environment depending on its thickness, color and structure, which differ from one site to another. The four major types of problematic wounds include ulcers (diabetic, venous, pressure) and burn wounds. Developing novel dressings helps us to improve the wound healing process in difficult patients. Recent advances in regenerative medicine and nanotechnology are revolutionizing the field of wound healing...

Hydrogels are composed of three-dimensional smart and/or hungry networks, which do not dissolve in water but swell considerably in an aqueous medium, demonstrating an extraordinary ability to absorb water into the reticulated structure. Such inherent feature is a subject of considerable scientific research interest which leads to a dominating path in extending their potential in hi-tech applications. Over the past decades, significant progress has been made in the field of hydrogels. Further, explorations are continuously being made in all directions at an accelerated pace for their extensive usage...

BACKGROUND: Among the 3 approved oral P2Y12 inhibitors for the treatment for patients with acute coronary syndrome (ACS), ticagrelor, but not prasugrel or clopidogrel, has been associated with off-target properties, such as improved endothelial-dependent vasomotion and increased adenosine plasma levels. METHODS: The HI-TECH study (NCT02587260) is a multinational, randomized, open-label, crossover study with a Latin squares design, conducted at 5 European sites, in which patients free from recurrent ischemic or bleeding events ≥30 days after a qualifying ACS were allocated to sequentially receive a 30 ± 5-day treatment with prasugrel, clopidogrel, and ticagrelor in random order...

This article outlines the development of IVF in Sri Lanka from the first successful births in the late 1990s and over the subsequent 15 years. It is based on anthropological fieldwork carried out at various points during this period. The piece focuses on the challenges entailed in achieving regulation of the new reproductive technologies against a backdrop of: (i) a bitter civil war; (ii) a complex mosaic of different religious traditions (specifically, Buddhism, Catholicism, Hinduism and Islam); and (iii) a shift towards neo-liberal marketization, particularly in relation to specialist and hi-tech medical interventions...

Oxidation of the primary OH groups in cellulose is a pivotal reaction both at lab and industrial scale, leading to the value-added products, i.e. oxidized cellulose which have tremendous applications in medicine, pharmacy and hi-tech industry. Moreover, the introduction of carboxyl moieties creates prerequisites for further cellulose functionalization through covalent attachment or electrostatic interactions, being an essential achievement designed to boost the area of cellulose-based nanomaterials fabrication...

Carbon atoms have the potential to produce a variety of fascinating all-carbon structures with amazing electronic and mechanical properties. Over the last few decades, several efforts have been made using experimental and computational techniques to functionalize graphene, carbon nanotubes and fullerenes for potential use in modern hi-tech electronic, medicinal, optical and nonlinear optical (NLO) applications. Since photons replaced electrons as a carrier of information, the field of NLO material design has drawn immense interest in contemporary materials science...

Allergy immunotherapy (AIT) is acknowledged to produce beneficial mid- and long-term clinical and immunologic effects and increased quality of life in patients with allergic respiratory diseases (such as allergic rhinoconjunctivitis and allergic asthma). However, poor adherence to AIT (due to intentional and/or non-intentional factors) is still a barrier to achieving these benefits. There is an urgent need for patient support programs (PSPs) that encompass communication, educational and motivational components...

The study was conducted on aircraft-building enterprise during production microcycle (before working shift start, during last working hour and in an hour after the shift end)--spectral analysis covered variability of heart rhythm in 70 male assembler riveters aged 25-59, divided into 2 groups in accordance with industrial equipment used. The group 1 used standard vibroinstrument, the group 2--pneumoinstruments with low vibration velocity parameters. Triple study during the working shift revealed in group 2 an adequate reaction of vegetative nervous system to vibration, in group 1 a negative trend was seen with centralization of regulatory processes and absence of adequate recovery in an hour after work...

Meniscal replacement to treat early osteoarthritis of the knee after meniscectomy may be accompanied by other surgical procedures to treat factors predisposing to a negative intervention outcome. Overload of the medial compartment in slight varus can be reduced by applying the new KineSpring system, which can promote the best possible outcome of a biodegradable meniscal scaffold implantation, without producing biomechanical and anatomical alterations of the joint. This is the first case report on the combination of these hi-tech and bio-tech techniques...

INTRODUCTION: Health care economics restricts many health centers from using hi-tech diagnostics equipment. Mercury manometers are used for calibration of pressure transducers. If standardized it would be a cost effective, simple alternative to transducers in low economic settings. AIM: To analyse the feasibility of mercury manometer usage in respiratory pressure measurement. MATERIALS AND METHODS: The experimental study was conducted with 30 healthy volunteers of age group 17-19 yrs...

A new approach to design multifunctional chitosan based nanohydrogel with enhanced glucose sensitivity, stability, drug loading and release profile are reported. Two approaches were followed for functionalization of chitosan based nanohydrogel with 3-APBA via EDC and 3-APTES. The effective functionalization, structure and morphology of Chitosan based IPN respectively were confirmed by FTIR, SEM and AFM. At physiological conditions, the glucose-induced volume phase transition and release profile of the model drug Alizarin Red with 1,2-diol structure (comparative to insulin as a drug as well as a dye for bio separation) were studied at various glucose concentrations, pH and ionic strengths...

Over 73% of hi-tech industry employees in Taiwan lack regular exercise. They are exposed to a highly variable and stressful work environment for extended periods of time, and may subsequently experience depression, detrimental to workers' physiological and mental health. In this cross-sectional survey, the authors explored the effect of an 8-week brisk walking program on the fatigue of employees in the hi-tech industry. The participants, from a hi-tech company in northern Taiwan, were randomly assigned to an experimental group (EG; 41 subjects, Mage = 33...

During the past decade, melanins and melanogenesis have attracted growing interest for a broad range of biomedical and technological applications. The burst of polydopamine-based multifunctional coatings in materials science is just one example, and the list may be expanded to include melanin thin films for organic electronics and bioelectronics, drug delivery systems, functional nanoparticles and biointerfaces, sunscreens, environmental remediation devices. Despite considerable advances, applied research on melanins and melanogenesis is still far from being mature...
