Effects of age/gender profiles and physical activity level on symmetry of lumbar muscle activation in pain-free older adults during various spinal movements.

Background: Back muscles simultaneously drive spinal movements and stabilize the trunk. Paraspinal muscle activity is presumed to be symmetric and gender-insensitive, and more activated with aging to protect the spine during functional tasks.

Research Question: Does over-activated and asymmetric behaviors exist in the pain-free elderly population which is affected by their physical activity levels?

Methods: Forty healthy participants (aged 64.

Horses with previous episodes of laminitis have altered insulin responses to seasonal oral sugar testing and grazing compared to horses with no known history of laminitis.

Forage is essential for equine health and performance, but intake of elevated pasture nonstructural carbohydrates (NSC) may exacerbate metabolic disorders. This study aimed to investigate the influence of laminitis history on metabolic and morphometric responses in grazing horses. Twelve non-pregnant mares (15 ± 3.

Extremism, racism and riots: exploring the political, social and cultural determinants of poor mental health.

The UK has seen an outbreak of riots after the death of three children in a knife attack. Misinformation about the suspect's heritage and religion was spread by social media, which was then used to incite violence and racism resulting in damage to property, terror and injuries. We put forward arguments that this was an extremist act and draw on the literature on terrorism, extremism and identity to put forward a deeper analysis of how this happened and what can be done to prevent future riots.

Modeling implications of the relationship between active and passive skeletal muscle mechanical properties.

It is challenging to obtain in vivo or in situ experimental data from human muscles due to the invasive nature of such measurements. As a result, many investigations of human performance, surgery, or skeletal adaptation are necessarily based on musculoskeletal models. The utility of such models will depend on the question being asked and the extent to which the model is sufficiently accurate to address that question.

Child Sexual Abuse and Boundary Violating Behaviors in Youth Serving Organizations: National Prevalence and Distribution by Organizational Type.

Many youth serving organizations (YSOs) implement child sexual abuse (CSA) prevention strategies. We examined the potential impact of those strategies by retrospectively estimating the prevalence of CSA and boundary violating behaviors experienced in five broad organizational settings: organized sports, religious organizations, music or arts programs, K-12 schools, and the "Big 6 settings" (i.e.

Dynamical systems theory applied to short walking trials.

Human walking is an extremely complex neuromuscular activity whose simplicity disappears when an attempt is made to provide a quantitative description of the process. The dynamical systems theory provides a framework for analyzing the stability and chaotic nature of dynamical systems, employing Floquet multipliers (FM) and long and short-term Lyapunov exponents (LE), respectively. This report compares FM and LE from three methods: method A (false nearest neighbors and numerical approximation), method B (false nearest neighbors and semi-analytical technique) and method C (singular value decomposition and semi-analytical technique).

The relationship between off-ice testing and on-ice performance in male youth Ice hockey players.

Specific tension of human muscle in vivo: a systematic review.

The intrinsic force production capability of human muscle can be expressed as "Specific Tension," or, the maximum force generated per cross-sectional area of muscle fibers. This value can be used to determine, for example, whether muscle quality changes during exercise, atrophy, disease, or hypertrophy. A value of 22.

Validation of Pelvis and Trunk Range of Motion as Assessed Using Inertial Measurement Units.

Trunk and pelvis range of motion (ROM) is essential to perform activities of daily living. The ROM may become limited with aging or with neuromusculoskeletal disorders. Inertial measurement units (IMU) with out-of-the box software solutions are increasingly being used to assess motion.

Mechanical Method for Rapid Determination of Step Count Sensor Settings.

With the increased push for personalized medicine, researchers and clinicians have begun exploring the use of wearable sensors to track patient activity. These sensors typically prioritize device life over robust onboard analysis, which results in lower accuracies in step count, particularly at lower cadences. To optimize the accuracy of activity-monitoring devices, particularly at slower walking speeds, proven methods must be established to identify suitable settings in a controlled and repeatable manner prior to human validation trials.

Astroviruses in terrestrial Malagasy mammals.

Small terrestrial mammals are major hosts of infectious agents responsible for zoonotic diseases. Astroviruses (AstVs)-the cause of non-bacterial gastroenteritis mainly affecting young children-have been detected in a wide array of mammalian and avian host species. However, understanding the factors that influence AstV infection within and across hosts is limited.

Systemic barriers hinder person-centered home and community based services (HCBS): Perspectives of service users and professionals.

Background: In response to the 2014 Final Settings Rule issued by the Centers for Medicaid and Medicare Services, home-and-community based services (HCBS) provider organizations strengthened person-centered (PC) planning for HCBS to improve participants' choice and control over their services. Despite the call for widespread adoption of PC services, systemic barriers influence service users' and professionals' experiences in receiving and delivering PC services.

Objective: This study describes the perspectives of HCBS professionals and users on systemic barriers that affect PC HCBS delivery.

Wrist Motion Assessment in Tennis Players using Three-Dimensional Motion Capture and Dynamic Electromyography.

 Tennis players often present with ulnar-sided wrist pain, which may reflect repetitive stress and/or faulty mechanics. There is a role for investigating the biomechanics of tennis strokes and how they may relate to wrist pathology. The purpose of this study was to investigate whether three-dimensional motion capture technology and dynamic electromyography (EMG), when used to study groundstrokes in elite junior tennis players, reveals patterns of upper extremity motion that may correlate with the development of clinically relevant pathology.

Human cytomegalovirus infection coopts chromatin organization to diminish TEAD1 transcription factor activity.

Human cytomegalovirus (HCMV) infects up to 80% of the world's population. Here, we show that HCMV infection leads to widespread changes in human chromatin accessibility and chromatin looping, with hundreds of thousands of genomic regions affected 48 hours after infection. Integrative analyses reveal HCMV-induced perturbation of Hippo signaling through drastic reduction of TEAD1 transcription factor activity.
