BACKGROUND CONTEXT: Compromise of pedicle screw purchase is a concern in maintaining rigid spinal fixation, especially with osteoporosis. Little consistency exists among various tapping techniques. Pedicle screws are often prepared with taps of a smaller diameter, which can further exacerbate inconsistency. PURPOSE: To determine whether a mismatch between tap thread depth (D) and pitch (P) and screw thread D and P affects fixation when under-tapping in osteoporotic bone...

An easy alkoxide-based sol-gel method using Ca(NO3)2·4H2O and tri-ethyl phosphate (PO(OC2H5)3; TEP) precursors employed to synthesize nano-hydroxyapatite (HAP). The structural characterization of samples was studied using XRD, TEM and elemental analysis of SEM. Scherrer and Williamson-Hall equations were applied to measurement of the crystallite size distributions and micro-strain of the synthesized HAP powder. The synthesized HAP nanoparticles were applied as an efficient sorbent for the microextraction in packed syringe (MEPS) of phthalate esters (PAEs) from water samples...

A tailor-made liquid membrane consisting of a resistive organic solvent (nitrobenzene, NB) and a highly selective non-ionic macrocyclic compound (bambus[6]uril, BU6) was employed for electromembrane extraction (EME) of inorganic anions. BU6 facilitates strong host-guest interactions of its internal cavity with selected inorganic anions only and its presence in the liquid membrane ensured excellent selectivity of the EME process. EME transfers were directly related to association constants between BU6 and inorganic anions and nearly absolute selectivity was achieved for EMEs of iodide, bromide and perchlorate...

INTRODUCTION: The aim of this systematic review is to establish the clinical impact of open (mesh and/or without mesh) and laparoscopic hernia repair (transabdominal pre-peritoneal (TAP) and/or totally extra-peritoneal (TEP)) on male fertility. The incidence of male infertility following various types of inguinal hernia repair is currently unknown. The lack of high-quality evidence has led to various speculations, suggestions and reliance on anecdotal experience in the clinical practice...

A simple and sensitive double injection/single detector flow injection analysis (FIA) method is proposed for the simultaneous kinetic determination of ascorbic acid (AA) and uric acid (UA). This method is based upon the difference between the rates of the AA and UA reactions with Fe(3+) in the presence of 1, 10-phenanthroline (phen). The absorbance of Fe(2+)/1, 10-phenanthroline (Fe-phen) complex obtained as the product was measured spectrophotometrically at 510nm. To reach a good accuracy in the differential kinetic determination via the mathematical manipulations of the transient signals, different criteria were considered in the selection of the optimum conditions...

Motor synchronization to the beat of an auditory sequence (e.g., a metronome or music) is widespread in humans. However, some individuals show poor synchronization and impoverished beat perception. This condition, termed "beat deafness", has been linked to a perceptual deficit in beat tracking. Here we present single-case evidence (L.A. and L.C.) that poor beat tracking does not have to entail poor synchronization. In a first Experiment, L.A., L.C., and a third case (L.V.) were submitted to the Battery for The Assessment of Auditory Sensorimotor and Timing Abilities (BAASTA), which includes both perceptual and sensorimotor tasks...

It has been proposed that the dopaminergic system and heritability may play roles in attention deficit/hyperactivity disorder (ADHD). We assessed the performance of healthy parents of children with ADHD in the finger tapping test (FTT) in this study, which is a reliable test and sensitive to central dopamine activity. A total of 16 parents of children with ADHD and 32 controls were enrolled. The FTT was conducted. The 16 healthy parents of children with ADHD exhibited a significantly poorer performance in the FTT, using the nondominant hand, than the 32 healthy controls...

The diagnosis of poorly differentiated synovial sarcoma (PD-SS) may be challenging due to overlapping morphologic features with other undifferentiated round cell sarcomas (URCS). Particularly relevant is the histologic overlap and shared BCOR overexpression between a subset of SS and URCS with various BCOR genetic abnormalities. Here we report a case of PD-SS lacking the canonical SS18-SSX gene fusion, but showing strong BCOR immunoreactivity and BCOR gene abnormalities by FISH which were misinterpreted as a URCS with BCOR gene rearrangements...

Motor synchronization is a critical part of musical performance and listening. Recently, motor control research has described how movements that contain more available degrees of freedom are more accurately timed. Previously, we demonstrated that stick tapping improves perception in a timing detection task, where percussionists greatly outperformed non-percussionists only when tapping along. Since most synchronization studies implement finger tapping to examine simple motor synchronization, here we completed a similar task where percussionists and non-percussionists synchronized using finger tapping; movement with fewer degrees of freedom than stick tapping...

Human geolocation is prefaced on the accuracy of the geographic precision of mapped isotopic values for drinking water. As most people live in cities, it becomes important to understand city water supplies and how the isotopic values uniquely reflect that city. This study investigated the isotopic distribution of δ(2) H and δ(18) O from sourced tap waters that were collected from across the Metro Vancouver (MV) area (n = 135). The results revealed that the isotopic values reflect their water sources with a range of 5...

We examined the item characteristics, the factor structure, and the concurrent validity of a trait measure of psychobiosocial states. In Study 1, Italian athletes (N = 342, 228 men, 114 women, Mage = 23.93, SD = 6.64) rated the intensity, the frequency, and the perceived impact dimensions of a psychobiosocial states scale, trait version (PBS-ST), which is composed of 20 items (10 functional and 10 dysfunctional) referring to how they usually felt before an important competition. In Study 2, the scale was cross validated in an independent sample (N = 251, 181 men, 70 women, Mage = 24...

BACKGROUND: The cerebrospinal fluid (CSF) leakage could be happened spontaneously or related to the procedures such as spinal anesthesia, epidural anesthesia, CSF tapping, intrathecal chemotherapy or other spinal procedures. The leakage of CSF leads to intracranial hypotension of which distinguishing clinical feature is orthostatic headache. The epidural blood patch is a gold-standard treatment for intracranial hypotension-related orthostatic headaches. OBJECTIVE: We conducted this study to compare the efficacy and number of epidural blood patches for spontaneous and iatrogenic orthostatic headaches...

Environmental stress can lead to oxidative stress resulting from an increase in reactive oxygen species (ROS) and involves redox adjustments. Natural rubber is synthesized in laticifers, which is a non-photosynthetic tissue particularly prone to oxidative stress. This paper reviews the current state of knowledge on the ROS production and ROS-scavenging systems in laticifers. These regulations have been the subject of intense research into a physiological syndrome, called Tapping Panel Dryness (TPD), affecting latex production in Hevea brasiliensis In order to prevent TPD occurrence, monitoring thiol content appeared to be a crucial factor of latex diagnosis...

: A critical feature of the human brain that gives rise to complex cognition is its ability to reconfigure its network structure dynamically and adaptively in response to the environment. Existing research probing task-related reconfiguration of brain network structure has concluded that, although there are many similarities in network structure during an intrinsic, resting state and during the performance of a variety of cognitive tasks, there are meaningful differences as well. In this study, we related intrinsic, resting state network organization to reconfigured network organization during the performance of two tasks: a sequence tapping task, which is thought to probe motor execution and likely engages a single brain network, and an n-back task, which is thought to probe working memory and likely requires coordination across multiple networks...
