Background: The aim of this paper was to identify the most appropriate allometric scaling model for expressing aerobic fitness, determined by maximal oxygen consumption (VO2max), that would allow comparisons across differing body types.

Methods: VO2max and body composition data were collected from untrained non-obese and obese participants (N.=126).

Osteoporosis knowledge and health beliefs among middle-aged men and women in the Southern United States.

Context: The most common skeletal disease, osteoporosis, causes bone fragility due to decreased bone mass and bone microarchitecture destruction. The health belief model is often applied to asymptomatic, prevention-related diseases such as osteoporosis. Steps to mitigate the insidious nature of osteoporosis, including education, motivation, and monitoring of bone mineral density, must begin at an earlier age.

Screening for depression among a sample of US college students who engage in recreational prescription opioid misuse.

Among student populations, literature has identified associations between prescription opioid misuse and symptoms of depression such as hopelessness, sadness, and emotional pain. Thus far, existing literature has yet to investigate associations between prescription opioid misuse and depression using validated screening instruments for depression when exploring such associations. The purpose of this study was to utilize a validated screening tool to explore quantifiable presence of depression among college students who engage in recreational prescription opioid misuse (RPOM).

Bone Mineral Density Among Men and Women Aged 35 to 50 Years.

Sun-related behaviors among individuals previously diagnosed with non-melanoma skin cancer.

Compared to the general population, the risk of developing non-melanoma skin cancer is considerably higher among individuals with a previous history of this condition. Protection from ultraviolet (UV) radiation is the primary evidence-based approach for minimizing this risk. This review was aimed to assess the prevalence of sun-safe behaviors in non-melanoma skin cancer survivors.

Risk Factors for Low Bone Mineral Density in Institutionalized Individuals with Developmental Disabilities.

Background: Persons with intellectual/developmental disabilities (IDD) are exposed to several factors, which have been determined as risks for osteoporosis. Many of these individuals are non-ambulatory, resulting in lack of weight bearing activity, which is well established as a major contributor to bone loss. The purpose of this study was to investigate risk factors for low bone mineral density (BMD) in persons with IDD residing in residential facilities.

Validity of ultrasound prediction equations for total and regional muscularity in middle-aged and older men and women.

To test the validity of published equations, 79 Caucasian adults (40 men and 39 women) aged 50-78 y had muscle thickness (MT) measured by ultrasound at nine sites of the body. Fat-free mass (FFM), lean soft tissue mass (LM) and total muscle mass (TMM) were estimated from MT using equations previously published in the literature. Appendicular LM (aLM) was estimated using dual-energy X-ray absorptiometry (DXA) and this method served as the reference criterion.

Characterization of a central Ca2+/calmodulin-dependent protein kinase IIalpha/beta binding domain in densin that selectively modulates glutamate receptor subunit phosphorylation.

The densin C-terminal domain can target Ca(2+)/calmodulin-dependent protein kinase IIα (CaMKIIα) in cells. Although the C-terminal domain selectively binds CaMKIIα in vitro, full-length densin associates with CaMKIIα or CaMKIIβ in brain extracts and in transfected HEK293 cells. This interaction requires a second central CaMKII binding site, the densin-IN domain, and an "open" activated CaMKII conformation caused by Ca(2+)/calmodulin binding, autophosphorylation at Thr-286/287, or mutation of Thr-286/287 to Asp.

Osteoporosis Knowledge, Self-Efficacy, and Beliefs among College Students in the USA and China.

Association of protein phosphatase 1 gamma 1 with spinophilin suppresses phosphatase activity in a Parkinson disease model.

Sustained nigrostriatal dopamine depletion increases the serine/threonine phosphorylation of multiple striatal proteins that play a role in corticostriatal synaptic plasticity, including Thr(286) phosphorylation of calcium/calmodulin-dependent protein kinase IIalpha (CaMKIIalpha). Mechanisms underlying these changes are unclear, but protein phosphatases play a critical role in the acute modulation of striatal protein phosphorylation. Here we show that dopamine depletion for periods ranging from 3 weeks to 10 months significantly reduces the total activity of protein phosphatase (PP) 1, but not of PP2A, in whole lysates of rat striatum, as measured using multiple substrates, including Thr(286)-autophosphorylated CaMKIIalpha.

Developmentally regulated alternative splicing of densin modulates protein-protein interaction and subcellular localization.

Densin is a member of the leucine-rich repeat (LRR) and PDZ domain (LAP) protein family that binds several signaling molecules via its C-terminal domains, including calcium/calmodulin-dependent protein kinase II (CaMKII). In this study, we identify several novel mRNA splice variants of densin that are differentially expressed during development. The novel variants share the LRR domain but are either prematurely truncated or contain internal deletions relative to mature variants of the protein (180 kDa), thus removing key protein-protein interaction domains.

Selective targeting of the gamma1 isoform of protein phosphatase 1 to F-actin in intact cells requires multiple domains in spinophilin and neurabin.

Protein phosphatase 1 (PP1) catalytic subunits dephosphorylate specific substrates in discrete subcellular compartments to modulate many cellular processes. Canonical PP1-binding motifs (R/K-V/I-X-F) in a family of proteins mediate subcellular targeting, and the amino acids that form the binding pocket for the canonical motif are identical in all PP1 isoforms. However, PP1gamma1 but not PP1beta is selectively localized to F-actin-rich dendritic spines in neurons.
