Developing a Profile of Canadian Children With Cerebral Palsy Who Require Augmentative and Alternative Communication.

Purpose: Cerebral palsy (CP) is the most prevalent motor disability affecting children. Many children with CP have significant speech difficulties and require augmentative and alternative communication (AAC) to participate in communication. Despite demonstrable benefits, the use of AAC systems among children with CP remains constrained, although research in Canada is lacking.

[Offer and participation in body practices and physical activities in primary health care in Brazil: analysis from 2014 to 2022].

The scope of this article is to analyze the temporal trend and macro-regional distribution of the options on offer in terms of collective activities of bodily practices and physical activities (BPPA) and the number of participants in primary health care, developed by all health professionals and by Physical Education Professionals in Brazil. It involved an ecological time-series study, using data from the Health Information System for Primary Health Care (Sisab) between 2014 and 2022, which was assessed using regression analysis and Joinpoint software. At the national level, the results revealed an increase in the number of collective BPPA activities and participants in primary health care developed by all health professionals and by Physical Education Professionals between 2014 and 2019, followed by a reduction in both in 2020.

Early-onset sleep alterations found in patients with amyotrophic lateral sclerosis are ameliorated by orexin antagonist in mouse models.

Sleep alterations have been described in several neurodegenerative diseases yet are currently poorly characterized in amyotrophic lateral sclerosis (ALS). This study investigates sleep macroarchitecture and related hypothalamic signaling disruptions in ALS. Using polysomnography, we found that both patients with ALS as well as asymptomatic and mutation carriers exhibited increased wakefulness and reduced non-rapid eye movement sleep.

PD-L1-CD80 interactions are required for intracellular signaling necessary for dendritic cell migration.

Programmed cell death protein 1 (PD-1) and programmed death ligand 1 (PD-L1) interactions are targets for immunotherapies aimed to reinvigorate T cell function. Recently, it was documented that PD-L1 regulates dendritic cell (DC) migration through intracellular signaling events. In this study, we find that both preclinical murine and clinically available human PD-L1 antibodies limit DC migration.

Distinct checkpoint and homolog biorientation pathways regulate meiosis I in Drosophila oocytes.

Mitosis and meiosis have two mechanisms for regulating the accuracy of chromosome segregation: error correction and the spindle assembly checkpoint (SAC). We have investigated the function of several checkpoint proteins in meiosis I of Drosophila oocytes. Increased localization of several SAC proteins was found upon depolymerization of microtubules by colchicine.

Bacterial sensor evolved by decreasing complexity.

Bacterial receptors feed into multiple signal transduction pathways that regulate a variety of cellular processes including gene expression, second messenger levels, and motility. Receptors are typically activated by signal binding to ligand-binding domains (LBDs). Cache domains are omnipresent LBDs found in bacteria, archaea, and eukaryotes, including humans.

Cyanobacteria and Chloroflexota cooperate to structure light-responsive biofilms.

Microbial mats are stratified communities often dominated by unicellular and filamentous phototrophs within an exopolymer matrix. It is challenging to quantify the dynamic responses of community members in situ as they experience steep gradients and rapid fluctuations of light. To address this, we developed a binary consortium using two representative isolates from hot spring mats: the unicellular oxygenic phototrophic cyanobacterium OS-B' (Syn OS-B') and the filamentous anoxygenic phototroph MS-CIW-1 (Chfl MS-1).

Inotodiol induces hepatocellular carcinoma apoptosis by activation of MAPK/ERK pathway.

Hepatocellular carcinoma(HCC) has a high mortality and morbidity rate and seriously jeopardizes human life. Chemicals and chemotherapeutic agents have been experiencing problems such as side effects and drug resistance in the treatment of HCC, which cannot meet the needs of clinical treatment. Therefore, finding novel low-toxicity and high-efficiency anti-hepatocellular carcinoma drugs and exploring their mechanisms of action have become the current problems to be solved in the treatment of HCC.

The effect of physical exercise and cognition-orientated interventions on post-stroke cognitive function: Protocol for an overview of reviews.

Background: Strokes are becoming more common, and with improving survival rates, the prevalence of stroke survivors has increased. Almost half of chronic stroke survivors are cognitively impaired, and healthcare services are struggling to manage these patients, leaving some feeling "abandoned". Several systematic reviews have investigated the effect of physical exercise and cognition-orientated interventions on post-stroke cognitive impairment, and have produced conflicting findings, making it difficult for clinicians and guideline producers to make evidence-based decisions.

Hypercapnic warm-up and re-warm-up-A novel experimental approach in swimming sprint.

The purpose of this study was to determine the effective warm-up protocol using an added respiratory dead space (ARDS) 1200 ml volume mask to determine hypercapnic conditions, on the swimming velocity of the 50 m time trial front crawl. Eight male members of the university swimming team, aged 19-25, performed three different warm-up protocols: 1) standardized warm-up in water (WUCON); 2) hypercapnic warm-up in water (WUARDS); 3) hypercapnic a 20-minute transition phase on land, between warm-up in water and swimming test (RE-WUARDS). The three warm-up protocols were implemented in random order every 7th day.

Joint trajectories of physical activity, health, and income before and after statutory retirement: A 22-year follow-up.

Background: Health behaviors, health, and income change during aging. However, no previous studies have examined, how they develop together over the transition to statutory retirement. We aimed to examine their joint development and to identify the determinants of any distinct trajectories.

A Mechanical Construction to Enhance the Stability and Safety of Lifting and Thrusting Manipulation of Acupuncture.

The therapeutic effectiveness of acupuncture relies on both safety and stability, making these factors essential in acupuncture manipulation research. However, manual manipulation introduces unavoidable inaccuracies, which can impact the reliability of research findings. To address this challenge, a unique lifting and thrusting manipulation control cannula was designed in this study, offering flexible adjustment of movement amplitude.

Stair-descent phenotypes in community-dwelling older adults determined using high-level balance tasks.

Background: Falls on stairs are a major cause of severe injuries among older adults, with stair descent posing significantly greater risks than ascent. Variations in stair descent phenotypes may reflect differences in physical function and biomechanical stability, and their identification may prevent falls.

Aims: This study aims to classify stair descent phenotypes in older adults and investigate the biomechanical and physical functional differences between these phenotypes using hierarchical cluster analysis.

SHP2 promotes the epithelial-mesenchymal transition in triple negative breast cancer cells by regulating β-catenin.

Purpose: Growing evidence suggests that the tyrosine phosphatase SHP2 is pivotal for tumor progression. Triple-negative breast cancer (TNBC) is the most lethal subtype of breast cancer, characterized by its high recurrence rate, aggressive metastasis, and resistance to chemotherapy. Understanding the mechanisms of tumorigenesis and the underlying molecular pathways in TNBC could aid in identifying new therapeutic targets.

Age-related differences in eye movements and the association with Archimedes spiral tracing performance in young and older adults.

Age-related hand motor impairments may critically depend on visual information though few studies have examined eye movements during tasks of hand function in older adults. The purpose of this study was to assess eye movements and their association with performance while tracing on a touchscreen in young and older adults. Eye movements of 21 young (age 20-38 years; 12 females, 9 males) and 20 older (65-85 years; 10 females, 10 males) adults were recorded while performing an Archimedes spiral tracing task, a common clinical assessment sensitive to age-associated impairments in hand function.

The Impact of Physical Therapy Postprofessional Education Programs on Productivity in a Large Academic Medical Center.

Introduction: Emerging evidence shows positive impact of postprofessional physical therapy education (residency and fellowship) specific to participants; however, outcomes on organizational impact are largely unknown. The purpose of this project was to describe the impact residency and fellowship training has on financial metrics. A secondary purpose of this case study was to describe trends associated with higher productivity.

Oculomotor challenges in macular degeneration impact motion extrapolation.

Macular degeneration (MD), which affects the central visual field including the fovea, has a profound impact on acuity and oculomotor control. We used a motion extrapolation task to investigate the contribution of various factors that potentially impact motion estimation, including the transient disappearance of the target into the scotoma, increased position uncertainty associated with eccentric target positions, and increased oculomotor noise due to the use of a non-foveal locus for fixation and for eye movements. Observers performed a perceptual baseball task where they judged whether the target would intersect or miss a rectangular region (the plate).

Dynamic Video Assessment of Axial Postural Abnormalities in Parkinson's Disease: A Pilot Study.

Background: Axial postural abnormalities (APAs) are frequent and disabling axial symptoms of Parkinson's disease (PD). Image-based measurement is considered the gold standard but may not accurately detect the true severity of APAs because these symptoms can appear or get worse under dynamic conditions.

Objective: The aim was to evaluate quantitative changes in APAs degree during prolonged standing and walking in both single- and dual-task conditions (motor + cognitive).

Effects of an external load on anticipatory mechanisms of handstand walking initiation in experienced gymnasts.

Anticipatory postural adjustments (APAs) are responsible for a successful first step execution in handstand walking. This study evaluates gymnasts' ability to adapt their APAs and stepping parameters in response to adding/removing an external load over repeated handstand walking initiation trials. Eighteen gymnasts performed five handstand walking initiation trials without load (PRE), eight trials with an external load (LOAD) and five trials with removed load (POST).

The eyes have it: Alcohol-induced eye movement impairment and perceived impairment in older adults with and without alcohol use disorder.

Background: While alcohol has been shown to impair eye movements in young adults, little is known about alcohol-induced oculomotor impairment in older adults with longer histories of alcohol use. Here, we examined whether older adults with chronic alcohol use disorder (AUD) exhibit more acute tolerance than age-matched light drinkers (LD), evidenced by less alcohol-induced oculomotor impairment and perceived impairment.

Method: Two random-order, double-blinded laboratory sessions with administration of alcohol (0.

Quantification of training-induced alterations in body composition via automated machine learning analysis of MRI images in the thigh region: A pilot study in young females.

The maintenance of an appropriate ratio of body fat to muscle mass is essential for the preservation of health and performance, as excessive body fat is associated with an increased risk of various diseases. Accurate body composition assessment requires precise segmentation of structures. In this study we developed a novel automatic machine learning approach for volumetric segmentation and quantitative assessment of MRI volumes and investigated the efficacy of using a machine learning algorithm to assess muscle, subcutaneous adipose tissue (SAT), and bone volume of the thigh before and after a strength training.

Crystallography of the litharge to massicot phase transformation from neutron powder diffraction data.

The crystallographic phase change from tetragonal litharge (α-PbO; P4/nmm) to orthorhombic massicot (β-PbO; Pbcm) has been studied by full-matrix Rietveld analysis of high-temperature neutron powder diffraction data collected in equal steps from ambient temperature up to 925 K and back down to 350 K. The phase transformation takes place between 850 and 925 K, with the coexisting phases having equal abundance by weight at 885 K. The product massicot remains metastable on cooling to near ambient temperature.
