Predicting Walking Capacity Outcomes After Moderate to High Intensity Locomotor Training in Chronic Stroke.

Purpose: Moderate-to-high intensity locomotor training (M-HIT) is strongly recommended in stroke rehabilitation but outcomes are variable. This study aimed to identify baseline clinical characteristics that predict change in walking capacity following M-HIT in chronic stroke.

Methods: This analysis used data from the HIT-Stroke Trial (N=55), which involved up to 36 sessions of either moderate or high intensity locomotor training.

Auricular Chondrocytes as a Cell Source for Scaffold-Free Elastic Cartilage Tissue Engineering.

Current tissue engineering (TE) methods utilize chondrocytes primarily from costal or articular sources. Despite the robust mechanical properties of neocartilages sourced from these cells, the lack of elasticity and invasiveness of cell collection from these sources negatively impact clinical translation. These limitations invited the exploration of naturally elastic auricular cartilage as an alternative cell source.

Georectified polygon database of ground-mounted large-scale solar photovoltaic sites in the United States.

Over 4,400 large-scale solar photovoltaic (LSPV) facilities operate in the United States as of December 2021, representing more than 60 gigawatts of electric energy capacity. Of these, over 3,900 are ground-mounted LSPV facilities with capacities of 1 megawatt direct current (MW) or more. Ground-mounted LSPV installations continue increasing, with more than 400 projects appearing online in 2021 alone; however, a comprehensive, publicly available georectified dataset including spatial footprints of these facilities is lacking.

Tilapia Fish Skin Treatment of Third-Degree Skin Burns in Murine Model.

This study explored the feasibility of using fish skin bandages as a therapeutic option for third-degree skin burns. Following the California wildfires, clinical observations of animals with third-degree skin burns demonstrated increased comfort levels and reduced pain when treated with tilapia fish skin. Despite the promises of this therapy, there are few studies explaining the healing mechanisms behind the application of tilapia fish skin.

A Fresh Glimpse into Cartilage Immune Privilege.

The increasing prevalence of degenerative cartilage disorders in young patients is a growing public concern worldwide. Cartilage's poor innate regenerative capacity has inspired the exploration and development of cartilage replacement treatments such as tissue-engineered cartilages and osteochondral implants as potential solutions to cartilage loss. The clinical application of tissue-engineered implants is hindered by the lack of long-term follow-up demonstrating efficacy, biocompatibility, and bio-integration.

Tissue Engineering of Canine Cartilage from Surgically Debrided Osteochondritis Dissecans Fragments.

This study in dogs explored the feasibility of using cartilage fragments removed and discarded during routine palliative surgery for osteochondritis dissecans (OCD) as a source of primary chondrocytes for scaffold-free cartilage tissue-engineering. Primary chondrocytes were obtained from three OCD donors and one age-matched healthy articular cartilage (HAC) donor. After monolayer expansion of primary cells, a three-dimensional spherical suspension culture was implemented.

Research Note: Evaluation of the incidence of white striping and underlying myopathic abnormalities affected by fast weight gain in commercially fed broiler chickens.

Significant improvements in genetics, nutrition, and food efficiency have had a great impact on the rapid growth of broilers, notably with increases in muscle mass. However, with rapid growth, the broiler industry has been negatively impacted by the increased incidence of myopathies, including white striping. White striping affects the pectoralis major muscle of broilers, particularly the larger breasts of rapidly growing modern commercial broiler lines.

Histological, Immunological, and Genetic Analysis of Feline Chronic Gingivostomatitis.

Feline chronic gingivostomatitis (FCGS) is an immune-mediated inflammatory condition affecting the oral mucosa that results in substantial pain and suffering. The goal of this study was to complete an in-depth immunohistochemistry analysis of affected FCGS mucosa, to perform and compare immune cell phenotypes in the blood of FCGS and healthy controls cats, and to determine a transcriptomic profile of the affected and normal oral mucosa of FCGS cats. We hypothesized that cats with FCGS would have circulating activated CD8+ T cells and that tissues would be infiltrated with activated B and T cells with a highly proinflammatory transcriptome.

A continuously updated, geospatially rectified database of utility-scale wind turbines in the United States.

Over 60,000 utility-scale wind turbines are installed in the United States as of October, 2019, representing over 97 gigawatts of electric power capacity; US wind turbine installations continue to grow at a rapid pace. Yet, until April 2018, no publicly-available, regularly updated data source existed to describe those turbines and their locations. Under a cooperative research and development agreement, analysts from three organizations collaborated to develop and release the United States Wind Turbine Database (USWTDB) - a publicly available, continuously updated, spatially rectified data source of locations and attributes of utility-scale wind turbines in the United States.

α6β2 nicotinic acetylcholine receptors influence locomotor activity and ethanol consumption.

Nicotinic acetylcholine receptors (nAChRs) in the mesolimbic dopamine system have been implicated in ethanol behaviors. In particular, work in genetically engineered mice has demonstrated that α6-containing nAChRs are involved in ethanol consumption and sedation. A limitation of these studies is that the alteration in the receptor was present throughout development.

Onshore industrial wind turbine locations for the United States up to March 2014.

Wind energy is a rapidly growing form of renewable energy in the United States. While summary information on the total amounts of installed capacity are available by state, a free, centralized, national, turbine-level, geospatial dataset useful for scientific research, land and resource management, and other uses did not exist. Available in multiple formats and in a web application, these public domain data provide industrial-scale onshore wind turbine locations in the United States up to March 2014, corresponding facility information, and turbine technical specifications.

Prolonged exposure for PTSD in a Veterans Health Administration PTSD clinic.

With the move toward dissemination of empirically supported treatments in the Veterans Health Administration (VHA), dissemination of additional data concerning the effectiveness of prolonged exposure (PE) among veterans is important. The authors present clinical treatment data from veterans with chronic posttraumatic stress disorder (PTSD) treated in a VHA PTSD clinic (N = 10). Veterans demonstrated significant reductions in total PTSD symptoms from pre- to posttreatment.

Risk factors for psychosocial dysfunction among enrollees in the State Children's Health Insurance Program.

Objective: The authors studied enrollees in the State Children's Health Insurance Program (SCHIP) (Title XXI) to characterize risk factors for psychosocial dysfunction among children of the working poor.

Methods: Medical and psychosocial variables were included in a survey completed by 393 parents of children enrolled in SCHIP. Regression analysis was used to examine the relationship between these variables and scores on the Pediatric Symptom Checklist, a measure of psychosocial dysfunction among children.

Automated charge capture at the point of care increases revenue.

Group practices can reduce lost charges, denied claims, and time-to-billing rates by using automated charge capture at the point of service. One orthopedic department had been experiencing many process-related problems associated with physician charge capture. To improve revenues, the physicians began using hand-held devices to input data during patients' office visits.

Exaggerated pressor and chronotropic response to chronic hyperinsulinemia in SH versus WKY rats.

Insulin resistance and the sympathetic nervous system have been suggested to be important factors in the blood pressure response to hyperinsulinemia. This study was designed to investigate whether the response to chronic hyperinsulinemia in 14-week-old SH rats (n = 6), which are reported to be insulin resistant and to have a hyperresponsive sympathetic nervous system, would differ from that in WKY rats (n = 5). Mean arterial pressure (MAP) and heart rate (HR) were monitored 19 h/day by computer.

High-fructose diet does not raise 24-hour mean arterial pressure in rats.

High intakes of the simple sugars--glucose, sucrose, and fructose--have been reported to raise significantly systolic pressure in rats. It is not clear, however, if under those conditions the acute measurement of blood pressure, especially with the tail-cuff technique, represents accurately the effect of the diet on mean arterial pressure throughout the day. In this study, 15 Sprague-Dawley rats (approximately 325 g) were chronically instrumented with arterial and venous catheters and placed on a diet containing 61% vegetable starch and 5% dextrose; seven rats remained on this diet throughout the study.
