BACKGROUND: There is not enough information on the effects of compression therapy in soccer players during recovery after matches. So the objective of this study was to examine the effect of wearing compression garments during soccer matches and during recovery period on physical responses. METHODS: Eighteen semi-professional soccer players participated in this study. A two-stage crossover design was chosen. Participants acted as controls in one match and were assigned to an experimental group (compression stockings group, full-leg compression group, shorts group) in the other match...

Z R Yang, F Sun, S Y Zhan
This paper reviews the concept of risk of bias, followed by demonstrating why assessment of risk of bias in systematic reviews should be different from that of quality of evidence, methodological quality, reporting quality, precision, and external validity. We also discuss the recent development of tools for risk of bias assessment, the problems with the tools themselves, and the challenges in using these tools. This review may help systematic reviewers understand risk of bias assessment and the use of assessment tools...

Purpose: To determine the presence of monocarboxylate transporter (MCT) in human and rabbit corneal epithelium and its role in transcellular fluorescein transportation in the cornea. Methods: The presence of MCTs in human and rabbit corneal epithelium was determined by RT-PCR and immunohistochemistry. Intracellular fluorescein uptake experiment was performed using cultured human corneal epithelial cells (HCECs). The involvement of MCT in fluorescein uptake was determined by addition of MCT inhibitors to HCECs and acute dry eye model on New Zealand albino rabbits by spectrophotometry, corneal impression cytology, and external eye photographs...

BACKGROUND/AIMS: Early detection and intervention may alter the disease course of subcortical vascular cognitive impairment (SVCI). Patients with SVCI have white matter ischemia that disrupts connections between the cortex and subcortical gray matter and therefore manifest various symptoms such as motor disturbances and behavioral/cognitive dysfunction. Reduced vocal loudness, or hypophonia, is one of the common motor symptoms of SVCI, but few studies have systematically investigated it in this patient population...

When interacting with other people, both children's biological predispositions and past experiences play a role in how they will process and respond to social-emotional cues. Children may partly differ in their reactions to such cues because they differ in the threshold for perceiving such cues in general. Theoretically, perceptual sensitivity (i.e., the amount of detection of slight, low-intensity stimuli from the external environment independent of visual and auditory ability) might, therefore, provide us with specific information on individual differences in susceptibility to the environment...

BACKGROUND: Prenatal phthalate exposure has been associated with behavioral problems and lower performance on measures of cognitive ability in children. However, the potential effect of phthalate exposure during the sensitive preconception period is unknown. OBJECTIVES: To estimate the association of maternal and paternal preconception urinary phthalate metabolite concentrations with child behavior and evaluate potential modification by child sex. METHODS: We used data from 166 children (111 singletons, 26 pairs of twins, and 1 set of triplets) born to 134 mothers and 100 fathers participating in a prospective preconception cohort study of subfertile couples from the Massachusetts General Hospital Fertility Center...

In this study, a regenerable magnetic ligand material (EDTA-mGO) was fabricated by binding chelating groups (EDTA) onto Fe3O4/graphene oxide and applied to remove U(VI) from aqueous solution. The sorption experiments were investigated under different experimental conditions, such as temperature, contact time and pH. EDTA-mGO showed fast removal capacity for U(VI) (<1.5h) with high sorption ability (277.43mg/g). The removal mechanisms mainly attributed to the metal-binding organic ligand (EDTA) and the electrostatic attractions between U(VI) and oxygenic functional groups...

Human immunodeficiency virus (HIV-1) reverse transcriptase is a major target for designing anti-HIV drugs. Developed inhibitors are divided into non-nucleoside analog reverse-transcriptase inhibitors (NNRTIs) and nucleoside analog reverse-transcriptase inhibitors (NRTIs) depending on their mechanism. Given that many inhibitors have been studied and for many of them binding affinity constants have been calculated, it is beneficial to analyze the chemical landscape of these families of inhibitors and correlate these inhibition constants with molecular structure descriptors...

Globally, waterborne organisms are the primary causative agents for the transmission of various forms of diarrheal diseases. For accurate diagnosis, molecular tools have gained considerable attention in the recent past. Molecular tools require DNA as the starting material for diagnosis, and hence, a prerequisite is the quality and integrity of DNA. To obtain high quality DNA rapidly, we have fabricated a microchip in poly(dimethyl siloxane) (PDMS) by soft lithography process. The microchip facilitated in-flow coating of chitosan on the magnetic nanoparticles, which under external mechanical vibration caused cell lysis and released DNA in the supernatant...

Telomeres, which are involved in cell division, carcinogenesis, and aging and constitute important therapeutic targets, are prone to oxidative damage. This propensity has been correlated with the presence of guanine-rich sequences, capable of forming four-stranded DNA structures (G-quadruplexes). Here, we present the first study on oxidative damage of human telomere G-quadruplexes without mediation of external molecules. Our investigation has been performed for G-quadruplexes formed by folding of GGG(TTAGGG)3 single strands in buffered solutions containing Na(+) cations (TEL21/Na(+))...

Peptidoglycan (PG) scaffolds are critical components of bacterial cell walls. They counter internal turgor pressure to prevent lysis and protect against external insults. It was recently discovered that various types of bacteria release large quantities of PG building blocks (D-amino acids) into their surrounding medium. Cultured bacteria were also found to incorporate D-amino acids (both natural and synthetic) from the medium directly into their PG scaffold. Together, these two processes may potentially function, in concert, to metabolically remodel PG in live host organisms...

BACKGROUND: Pain is a common feature of childhood and adolescence around the world, and for many young people, that pain is chronic. The World Health Organization (WHO) guidelines for pharmacological treatments for persisting pain in children acknowledge that pain in children is a major public health concern of high significance in most parts of the world. Views on children's pain have changed over time and relief of pain is now seen as important. In the past, pain was largely dismissed and was frequently left untreated, and it was assumed that children quickly forgot about painful experiences...

Chemistry quickly moves from a molecular science to a systems science. This requires spatial and temporal control over the organisation of molecules and molecular assemblies. Whilst Nature almost by default (transiently) organises her components at multiple different length scales, scientists struggle to realise even relatively straightforward patterns. In the past decades, supramolecular chemistry has taught us the rules to precisely engineer molecular assembly at the nanometre scale. At higher length scales, however, we are bound to top-down nanotechnology techniques to realise order...

Oxidation of [Pt((II))Cl(terpy)](+) (terpy = 2,2':6',2''-terpyridine) has been attempted with several oxidizing agents and under different experimental conditions in order to obtain a Pt(iv) complex suitable for the conjugation to nanovectors to be used in drug delivery targeting for anticancer therapy. The best compromise in terms of yield and purity of the final complex was obtained by microwave-assisted reaction at 70 °C in 50% aqueous H2O2 for 2 h. Under these conditions the quantitative formation of [Pt((IV))Cl(OH)2(terpy)](+) was observed...

Across 4,151 participants, the authors demonstrate a novel framing effect, attribute matching, whereby matching a salient attribute of a decision frame with that of a decision's options facilitates decision-making. This attribute matching is shown to increase decision confidence and, ultimately, consensus estimates by increasing feelings of metacognitive ease. In Study 1, participants choosing the more attractive of two faces or rejecting the less attractive face reported greater confidence in and perceived consensus around their decision...
