Osteoporosis is characterized by a reduction in bone mass and bone mineral density, which weakens the bone. Due to the side effects associated with drugs that are currently used to treat this disease, an increasing number of studies have focused on the research of effective ingredients derived from natural products. In particular, polysaccharides extracted from Chinese herbal medicines have received increasing attention. In this study, we isolated a homogeneous polysaccharide (COP90-1) from the dried rhizomes of Curculigo orchioides, a famous traditional Chinese medicine that is widely used in China, and determined its structure using the combined methods of chemical and spectral analyses...

Mental health problems affect people with intellectual disabilities (ID) at rates similar to or in excess of the non-ID population. People with severe ID are likely to have persistent mental health problems. In this systematic review (PROSPERO 2015:CRD42015024469), we identify and evaluate the methodological quality of available measures of mental health problems or well-being in individuals with severe or profound ID. Electronic searches of ten databases identified relevant publications. Two reviewers independently reviewed titles and abstracts of retrieved records (n=41,232) and full-text articles (n=573)...

Herein, bimetallic dendritic core-shell AuPd@Au nanocrystals (AuPd@Au NCs) were prepared by a simple one-pot aqueous method using xanthine as a green growth-directing agent. By virtue of the enhanced peak currents in the H2O2 reduction catalyzed by AuPd@Au NCs, a label-free immunosensor was constructed for the detection of prostate specific antigen (PSA). The immunosensor exhibited significantly improved analytical performance for the assay of PSA with wide linear range of 0.1-50ngmL(-1) and low detection limit of 0...

Despite availability of high quality medical records, health care systems often do not have the resources or tools to utilize these data efficiently. Yet, hospital-based, laboratory-confirmed records may pave the way for building reliable surveillance systems capable of monitoring temporal trends of emerging infections. In this communication, we present a new tool to compress and visualize medical records with a local population profile (LPP) approach, which transforms information into statistically comparable patterns...

Radiostereometric analysis (RSA) is the gold standard for evaluating micromotions of orthopaedic implants. The method is applied for identifying novel design weaknesses in endoprostheses. Current research frequently assesses relatively short time periods. Short-term RSA studies have been widely used for predicting the long-term stability of many hip prosthetic designs, but only a few studies have focused on uncemented hip implants, especially for extended periods. The purpose of this study was to analyse the migration pattern of the Cerafit® femoral stem within 10 years and to verify the predictive value of short-term RSA after 2 years for this uncemented femoral hip stem...

In this month's issue, Brooks et al.(1) examine the role of organoleptic perception and its association with bacteriologic drinking water quality in the Nyanza Province of western Kenya. This study focuses on two important issues relevant for drinking water in the new Sustainable Development Goals (SDGs)(2): human sensory perception and the measures of water safety, and the need to be able to measure drinking water quality in resource limited settings. To address the lack of studies, the authors researched how household members' perception of taste, odor, or overall quality were linked to measured levels of Escherichia coli via two detection methods: IDEXX Colilert(™) Quantitray (Colilert) and the Compartment Bag Test (CBT)...

Protein-protein interactions (PPIs) play a very large part in most cellular processes. Although a great deal of research has been devoted to detecting PPIs through high-throughput technologies, these methods are clearly expensive and cumbersome. Compared with the traditional experimental methods, computational methods have attracted much attention because of their good performance in detecting PPIs. In our work, a novel computational method named as PCVM-LM is proposed which combines the probabilistic classification vector machine (PCVM) model and Legendre moments (LMs) to predict PPIs from amino acid sequences...

Background: Research findings suggest that attitudes towards psychotherapy predict willingness to seek therapy. However, understanding how medical students think about using and referring their patients for psychotherapy is limited. Aims: The aims of this study are to measure medical students' attitudes towards professional help seeking, and to investigate the reasons for whether or not they would refer their patients to psychotherapy in their future role as doctors. Method: The participants were 127 medical students in their first and second year of the MBBS4 programme at the Cyprus campus of St George's University of London, who completed a self-report measure of attitudes towards psychotherapy and a semi-structured interview...

Pulse-wave elastography (SWE) that is one of the mostly used methods in the recent years holds important place in assessment of liver fibrosis. However there is no exact information on the results of liver elastography in healthy pregnant women in the world literature. The aim of the study was to investigate theSWE parameters of liver elastography in practically healthy pregnant women. The subject of the research was 50 practically healthy pregnant women within 18-45 years old (mean age 27.7±0.7). The pregnant women with genital and extragenital diseases were not included to the research...

Macroautophagy/autophagy is an evolutionarily well-conserved cellular degradative process with important biological functions that is closely implicated in health and disease. In recent years, quantitative mass spectrometry-based proteomics and chemical proteomics have emerged as important tools for the study of autophagy, through large-scale unbiased analysis of the proteome or through highly specific and accurate analysis of individual proteins of interest. At present, a variety of approaches have been successfully applied, including (i) expression and interaction proteomics for the study of protein post-translational modifications, (ii) investigating spatio-temporal dynamics of protein synthesis and degradation, and (iii) direct determination of protein activity and profiling molecular targets in the autophagic process...

In 2010, the article Location and Analysis of Emergency Management Point of Distributions (PODs) for Hurricane Ike was published in the Journal of Emergency Management. Using a program titled point of distribution locator (POD Locator 1.0), the article reported a 46 percent improvement in positioning PODs over the locations selected by emergency managers during Hurricane Ike in 2008. While the program could produce more effective POD locations for a given situation, a major weakness of the program was the difficulty with which population and location data were manually entered into the program for subsequent analysis...

Yuan Wang, Quan Yuan, Liang Xie
Aging is characterized by time-dependent functional decline, which results in the reduced ability to cope with physiological challenges. The aging process can be affected by genetic factors, environment factors, epigenetic factors, and several stochastic factors. Epigenetic marker alteration during aging has been widely monitored and studied recently, since these epigenetic alterations are theoretically reversible. Histone post-translational modifications have been found to play a crucial role in epigenetic alteration during aging, among which histone methylation and histone acetylation are emerging as two well-documented modification methods...

Stress is a common reaction to an environmental adversity, but a dysregulation of the stress response can lead to psychiatric illnesses such as major depressive disorder (MDD), post-traumatic stress disorder (PTSD), and anxiety disorders. Yet, not all individuals exposed to stress will develop psychiatric disorders; those with enhanced stress resilience mechanisms have the ability to adapt successfully to stress without developing persistent psychopathology. Notably, the potential to enhance stress resilience in at-risk populations may prevent the onset of stress-induced psychiatric disorders...

Transitionmetal oxides nanoparticles capsuled in amorphous carbon nanotubes (ACNTs) are attractive anode materials of lithium ion batteries (LIBs). Here we firstly designed a fast and universal method with a hydromechanics conception which is called Marangoni flow to fabricating transition bimetal oxides (TBOs) in ACNTs composite with a better electrochemistry performance. Maragoni flows can produce a liquid column with several centimeters high in a tube with one side immersion in the liquid. The key point to induce a Marangoni flow is to make a gradient of the surface tension between the surface and the inside of the solution...
