Purpose: Geriatric physical therapy (PT) has evolved since 2011, when the Essential Competencies (ECs) in the Care of Older Adults at the Completion of the Entry-level Physical Therapy Professional Program of Study were published. The purpose of the ECs was to ensure that all entry-level physical therapists were prepared to meet the unique needs of the growing older adult population. Changes in population demographics, medical and research advances, coupled with advancements in the profession of PT, necessitate a revision of the ECs.

Air-breathing vertebrates face many physiological challenges while breath-hold diving. In particular, they must endure intermittent periods of declining oxygen (O) stores, as well as the need to rapidly replenish depleted O at the surface prior to their next dive. While many species show adaptive increases in the O storage capacity of the blood or muscles, others increase the oxidative capacity of the muscles through changes in mitochondrial arrangement, abundance, or remodeling of key metabolic pathways.

At cold winter temperatures, juvenile salmonids typically spend much of their time sheltering from predators, which negatively impacts foraging for food. Previous work shows that inter-individual variation in mitochondrial efficiency explains variation in food intake, growth and metabolic rate. Here, we examine whether inter-individual variation in mitochondrial efficiency predicts sheltering as a proxy of foraging patterns for overwintering juvenile Atlantic salmon ().

The crucial role of aerobic energy production in sustaining eukaryotic life positions mitochondrial processes as key determinants of an animal's ability to withstand unpredictable environments. The advent of new techniques facilitating the measurement of mitochondrial function offers an increasingly promising tool for conservation approaches. Herein, we synthesize the current knowledge on the links between mitochondrial bioenergetics, ecophysiology and local adaptation, expanding them to the wider conservation physiology field.

While the impact of spirituality as it relates to quality of life post-liver transplant (LT) has been studied, there are limited data showing how religious affiliation impacts objective measures such as survival. The aim of the study is to investigate whether LT recipients who identified as having a religious affiliation had better clinical outcomes when compared to LT recipients who did not. Religious affiliation is obtained as part of general demographic information for patients within our institution (options of "choose not to disclose" and "no religious affiliation" are available).

Article Synopsis
  • Human microbiota begins forming at birth, influenced by maternal and environmental microbes, with core theories suggesting that initial colonizers impact community development.
  • Research involving 1,288 UK neonates revealed three distinct gut microbiota profiles, each led by specific microbial species affected by factors like maternal age and ethnicity.
  • Bifidobacteria, especially B. breve, were identified as key players in fostering stable gut microbiota and resisting pathogens, supporting their importance as primary colonizers in early life.

Predicting the mechanical properties of powder mixtures without extensive experimentation is important for model driven design in solid dosage form manufacture. Here, a new binary interaction-based model is proposed for predicting the compressibility and compactability of directly compressed pharmaceutical powder mixtures based on the mixture composition. The model is validated using blends of MCC, lactose and paracetamol or ibuprofen.

Community Based Natural Resource Management (CBNRM) is presented as an equitable approach, particularly relative to strict types of Area-based conservation. In Zambia, traditional and formal, contemporary institutions were combined to leverage CBNRM for natural resource management. We investigate whether and how this shift in conservation approach and interaction between institutions works in practice, and to what extent it produces more equitable governance processes.

Drawing on 662 studies from 102 countries, we present a systematic review of published empirical studies about site-level biodiversity conservation initiated between 1970 and 2019. Within this sample, we find that knowledge production about the Global South is largely produced by researchers in the Global North, implying a neocolonial power dynamic. We also find evidence of bias in reported ecological outcomes linked to lack of independence in scientific studies, serving to uphold narratives about who should lead conservation.

Diving animals must sustain high muscle activity with finite oxygen (O2) to forage underwater. Studies have shown that some diving mammals exhibit changes in the metabolic phenotype of locomotory muscles compared with non-divers, but the pervasiveness of such changes across diving animals is unclear, particularly among diving birds. Here, we examined whether changes in muscle phenotype and mitochondrial abundance are associated with dive capacity across 17 species of ducks from three distinct evolutionary clades (tribes) in the subfamily Anatinae: the longest diving sea ducks, the mid-tier diving pochards and the non-diving dabblers.

Given the pathological role of Tau aggregation in Alzheimer's disease (AD), our laboratory previously developed the novel Tau aggregation inhibitor peptide, RI-AG03. As Tau aggregates accumulate intracellularly, it is essential that the peptide can traverse the cell membrane. Here we examine the cellular uptake and intracellular trafficking of RI-AG03, in both a free and liposome-conjugated form.
