The purpose of this study was to determine the braking and propulsive phase kinetic variables underpinning reactive strength in highly trained sprint athletes in comparison to a non-sprint trained control group. Twelve highly trained sprint athletes and twelve non-sprint trained participants performed drop jumps (DJs) from 0.25m, 0.50m and 0.75m onto a force plate. One familiarization session was followed by an experimental testing session within the same week. Reactive strength index (RSI), contact time, flight time, and leg stiffness were determined...

BACKGROUND: Ergonomic education in housework that aims to facilitate behavior change is important for women with upper limb repetitive strain injury. Therapists usually conduct such programs based on implicit reasoning. Making this reasoning explicit is important in contributing to the profession's knowledge. AIM: To construct a conceptual representation of how occupational therapists make clinical decisions for such program. METHOD: Based on a constructivist-grounded theory methodology, data were collected through in-depth interviewing with 14 occupational therapists from a major hospital in Singapore...

We investigated the incidence of post-intubation hypotension (PIH) in hemodynamically stable patients with STEMI requiring rapid sequences intubation (RSI) and medicated with ketamine or midazolam as induction agent. STEMI patients admitted between 1st January 2009 and 1st January 2017 who did not receive any type of inotropic support before the endotracheal intubation (ETI) was reviewed. PIH was defined as a reduction greater than 20% or a drop of systolic blood pressure (SBP) below 90 mmHg within 10 min from the administration of the induction agent [ketamine (1 mg/kg) or midazolam (0...

Importance: Laryngopharyngeal reflux (LPR) is a common disorder with protean manifestations in the head and neck. In this retrospective study, we report the efficacy of a wholly dietary approach using alkaline water, a plant-based, Mediterranean-style diet, and standard reflux precautions compared with that of the traditional treatment approach of proton pump inhibition (PPI) and standard reflux precautions. Objective: To determine whether treatment with a diet-based approach with standard reflux precautions alone can improve symptoms of LPR compared with treatment with PPI and standard reflux precautions...

Although previous results showed that β-cyclodextrin-hemin complex (β-CDH) could induce tomato lateral root (LR) formation, the corresponding downstream messengers are still not fully understood. In this report, similar to the inducing effects of exogenously applied hydrogen peroxide (H2O2), we discovered that β-CDH elicited RBOH1 transcript upregulation, endogenous H2O2 accumulation, and thereafter tomato LR development. Above responses were sensitive to dimethylthiourea (DMTU) and ascorbic acid (AsA), two membrane-permeable scavengers of H2O2, showing that accumulation of H2O2 and LR formation were significantly blocked...

PURPOSE: Our goal was to determine whether tumour radiosensitivity is associated with activation of the immune system across all tumour types as measured by two gene expression signatures (GESs). METHODS: We identified 10,240 genomically profiled distinct solid primary tumours with gene expression analysis available from an institutional de-identified database. Two separate GESs were included in the analysis, the radiosensitivity index (RSI) GES (a 10-gene GES as a measure of radiosensitivity) and the 12-chemokine (12-CK) signature (a 12-gene GES as a measure of immune activation)...

Acupuncture is considered to be a promising alternative therapy for depression. Nevertheless, up to now, it remains controversial on the effects exerted by acupuncture on behavioral changes in depression models. Consequently, it's necessary to develop a systematic review and meta-analysis to assess the effect of acupuncture for model rats of depression. Ultimately, 90 studies involving 1861 models were identified. Behavioral indicators including the number of crossings (NC) and the number of rearings (NR) in open field test (OFT), the capacity of sucrose intake (CSI) and the rate of sucrose intake (RSI) in sucrose intake test (SIT), final weight (FW) and gain weight (GW) were employed as main outcomes in depression model rats...

Rapid sequence intubation (RSI) is the most common method of airway control in the emergency department (ED).(1,2) Administration of an anesthetic agent and a neuromuscular blocking agent (NMBA) optimizes conditions for tracheal intubation and is thought to minimize the risk of aspiration.(3-10) Evidence suggests that RSI improves first pass success and reduces complications in the critically ill.(11-14) This article is protected by copyright.

BACKGROUND: Diffusion imaging has demonstrated sensitivity to structural brain changes in Alzheimer's disease (AD). However, there remains a need for a more complete characterization of microstructural alterations occurring at the earliest disease stages, and how these changes relate to underlying neuropathology. This study evaluated the sensitivity of restriction spectrum imaging (RSI), an advanced diffusion magnetic resonance imaging (MRI) technique, to microstructural brain changes in mild cognitive impairment (MCI) and AD...

The purpose of this study was to determine the relationship between ground reaction force (GRF) variables to jump height, jump time, and the Reactive Strength Index (RSI). Twenty-six Division I male soccer players performed three maximum effort CMJs on a dual-force platform system that measured three-dimensional kinetic data. The trial producing peak jump height was used for analysis. Vertical GRF (Fz) variables were divided into unloading, eccentric, amortization, and concentric phases and correlated to jump height, RSI (RSI= Jump height/jump time), and jump time (from start to takeoff)...
