Alterations in the lumbo-pelvic coordination denote changes in neuromuscular control of trunk motion as well as load sharing between passive and active tissues in the lower back. Differences in timing and magnitude aspects of lumbo-pelvic coordination between patients with chronic low back pain (LBP) and asymptomatic individuals have been reported; yet, the literature on lumbo-pelvic coordination in patients with acute LBP is scant. A case-control study was conducted to explore the differences in timing and magnitude aspects of lumbo-pelvic coordination between females with (n=19) and without (n=19) acute LBP...

Layered transition-metal dichalcogenides have attracted great interest in the last few years. Thinned down to the monolayer limit they change from an indirect band structure to a direct band gap in the visible region. Due to the monolayer thickness the inversion symmetry of the crystal is broken and spin and valley are coupled to each other. The degeneracy between the two equivalent valleys, K and K', respectively, can be lifted by applying an external magnetic field. Here, we present photoluminescence measurements of CVD-grown tungsten disulphide (WS2) monolayers at temperatures of 2 K...

BACKGROUND: Meta-analyses indicated the breakdown of copper homeostasis in the sporadic form of Alzheimer's disease (AD), comprising copper decreases within the brain and copper increases in the blood and the pool not bound to ceruloplasmin (non-Cp Cu, also known in the literature as "free" copper). The calculated non-Cp Cu (Walshe's) index has many limitations. METHODS: A direct fluorescent method for non-Cp Cu detection has been developed and data are presented herein...

Human movement analysis is an important part of biomechanics and rehabilitation, for which many measurement systems are introduced. Among these, wearable devices have substantial biomedical applications, primarily since they can be implemented both in indoor and outdoor applications. In this study, a Trunk Motion System (TMS) using printed Body-Worn Sensors (BWS) is designed and developed. TMS can measure three-dimensional (3D) trunk motions, is lightweight, and is a portable and non-invasive system. After the recognition of sensor locations, twelve BWSs were printed on stretchable clothing with the purpose of measuring the 3D trunk movements...

BACKGROUND: There are two methods for ventilation in gynecological laparoscopy: volume-controlled ventilation (VCV) and pressure-controlled ventilation (PCV). OBJECTIVE: To compare the lung mechanics, hemodynamic response and arterial blood gas analysis and gas exchange of two modes of VCV and PCV using laryngeal mask airway (LMA) at different time intervals. MATERIALS AND METHODS: Sixty infertile women referred for diagnostic laparoscopy, based on ventilation mode, were randomly divided into two groups of VCV (tidal volume: 10 ml/kg) and PCV...

Clostridium perfringens is an important cause of foal necrotizing enteritis and canine acute hemorrhagic diarrhea. A major virulence determinant of the strains associated with these diseases appears to be a beta-sheet pore-forming toxin, NetF, encoded within a pathogenicity locus (NetF locus) on a large tcp-conjugative plasmid. Strains producing NetF also produce the putative toxin NetE, encoded within the same pathogenicity locus, as well as CPE enterotoxin and CPB2 on a second plasmid, and sometimes the putative toxin NetG within a pathogenicity locus (NetG locus) on another separate large conjugative plasmid...

INTRODUCTION: The Mucopolysaccharidoses (MPS) are rare inherited metabolic disorders. They are characterized by the progressive systemic deposition of Glycosaminoglycans (GAGs). GAGs accumulate in the myocardium and the cardiac valves. Enzyme Replacement Therapy (ERT) is available for MPS I, II, and VI. However, ERT does not appear to improve cardiac valve disease in patients with valve disease present at the start of ERT. AIM: To evaluate the cardiac involvement in Egyptian children with MPS...

MATERIALS AND METHODS: This split-mouth randomized, clinical trial performed on 67 children between 3 and 6 years with two primary mandibular second molars requiring pulp treatment. After pulp therapy, the teeth were randomly assigned to stainless steel crown (SSC) or FRC crown groups...

The explicit and semi-implicit schemes in flow simulations involving complex geometries and moving boundaries suffer from time-step size restriction and low convergence rates. Implicit schemes can be used to overcome these restrictions, but implementing them to solve the Navier-Stokes equations is not straightforward due to their non-linearity. Among the implicit schemes for nonlinear equations, Newton-based techniques are preferred over fixed-point techniques because of their high convergence rate but each Newton iteration is more expensive than a fixed-point iteration...

Accurate measurement of Human epidermal growth factor receptor (HER2) gene expression is central for breast or stomach cancer therapy orientation and prognosis. The current standards testing methods for HER2 expression are immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH). In the current study, we explored the use of quantitative real time reverse transcription-PCR (RT-qPCR) as a potential method for the accurate relative quantification of the HER2 gene using formalin fixed paraffin embedded (FFPE) breast cancer biopsy samples...

AIMS: Reestablishment of bladder function in patients with spinal cord injury (SCI) is a clinical priority. Our objectives were to determine whether SCI-localized inhibition of purinergic P2X7 receptors (P2X7R) improve bladder function by decreasing afferent signals mediated by urothelial P2X3R. MAIN METHODS: Systemic inhibition of P2X7R may improve locomotion in rodent SCI models; however, beneficial effects on bladder function and its physiological mechanisms have not been evaluated...

: The purpose of this study was to examine the physiological characteristics of an elite centenarian cyclist who, at 101 years old, established the one-hour cycling record for individuals ≥ 100 years old (24.25 km) and to determine the physiological factors associated with his performance improvement two years later at 103 years old (26.92 km; +11%). Before each record, he performed an incremental test on a cycling ergometer. For two years, he trained 5,000 km a year with a polarized training that involved cycling 80% of mileage at "light" RPE ≤ 12 and 20% at "hard" RPE ≥ 15 at a cadence between 50 and 70 rpm...

Numerous beautiful rhinoplasty results have been created by closed rhinoplasty techniques over the past 100 years. This operation was mainly a "reduction" surgery. Overaggressive reduction rhinoplasty is not a hallmark of the closed approach per se, but represents the result of inappropriate aesthetic appraisal, inadequate technical execution, or lack of sound anatomical understanding. Clearly, an operation based primarily on reduction intrinsically exposes the surgeon to the possibility of excessive diminution of support structures and consequently undesirable side effects...

In the post-genome age, proteomics is receiving significant attention because they provide an invaluable source of biological structures and functions at the protein level. The search for disease-specific biomarkers for diagnostic and/or therapeutic applications is one of the areas that proteomics is having a significant impact. Thus, the identification of a "good" biomarker enables a more accurate early diagnosis and prognosis of disease. Rapid advancements in mass spectrometry (MS) instrumentation, liquid chromatography MS (LCMS), protein microarray technology, and other protein profiling methodologies have a substantial expansion of our toolbox to identify disease-specific protein and peptide biomarkers...

Human doublecortin (DCX) mutations are associated with severe brain malformations leading to aberrant neuron positioning (heterotopia), intellectual disability and epilepsy. The Dcx protein plays a key role in neuronal migration, and hippocampal pyramidal neurons in Dcx knockout (KO) mice are disorganized. The single CA3 pyramidal cell layer observed in wild type (WT) is present as two abnormal layers in the KO, and CA3 KO pyramidal neurons are more excitable than WT. Dcx KO mice also exhibit spontaneous epileptic activity originating in the hippocampus...
