BACKGROUND: Exercise of the spinal muscles is recommended for a variety of rehabilitative reasons but it is not always clear whether interventions are effective in improving the performance of the muscles or whether their benefit is elicited via other mechanisms. OBJECTIVE: To explore the effects of an exercise intervention on the size and exercise performance of the lumbar spine extensor muscles. METHODS: Eleven healthy participants undertook a four week programme of exercise...

OBJECTIVE: Loss of skeletal muscle function is linked to increased risk for loss of health and independence in older adults. Dietary interventions that can enhance aging muscle function, alone or in combination with exercise, may offer an effective way to reduce these risks. The goal of this study was to evaluate the muscular effects of beta-hydroxy-beta-methylbutyrate (HMB) and beta-alanine (β-Ala) co-supplementation in aged Sprague-Dawley rats with voluntary access to running wheels (RW)...

BACKGROUND: Studies have consistently demonstrated the negative impact of childhood sexual abuse (CSA) on intimate relationships. The majority of studies have focused on revictimization in at-risk or clinical samples, with very few addressing the impact of CSA on otherwise well-functioning adults and even fewer investigating the psychological mechanisms involved. To fill this gap, this study focuses on the effect of CSA on "normative" (nonviolent) romantic relationships in otherwise well-functioning young women, and the mediating role of personality dimension self-criticism and attachment in this regard...

Idiopathic pulmonary fibrosis (IPF) is a chronic lung disorder that is characterized by aberrant tissue remodeling and the formation of fibroblastic foci that are composed of fibrogenic myofibroblasts. TGF-β1 is one of the factors that are responsible for fibrosis as it promotes fibroblast to myofibroblast differentiation (FMD) and is associated with up-regulation of α-smooth muscle actin. Therefore, inhibition of FMD may represent an effective strategy for the treatment of IPF. Here, we describe the treatment of human lung fibroblasts (WI-38 and HFL-1 cells) with cyclosporine A (CsA), which reduces TGF-β1-induced FMD via degradation of hypoxia-inducible factor-1α (HIF-1α)...

We investigated the effects of S1P3 deficiency on the age-related atrophy, decline of force and regenerative capacity of soleus muscle from 23-month-old male mice. During ageing, in old wild type mice, soleus mass and muscle fiber cross-sectional area (CSA) were reduced by about 26% and 24%, respectively, compared to the adult muscle. By contrast, the mass and fiber CSA of old S1P3-null soleus were comparable to the adult muscle. Moreover, in wild type soleus twitch and tetanic tensions diminished from adult to old age...

INTRODUCTION: Achieving a secure airway in rabbits is generally considered more difficult than in cats or dogs. Their relatively large tongue, small oropharyngeal cavity and glottis limit direct visualization. A rabbit-specific supraglottic airway device (SGAD) may offer benefits over blind orotracheal intubation. ANIMALS AND METHODS: Fifteen adult New Zealand white rabbits were randomized to SGAD or orotracheal intubation (ETT). All animals were sedated with dexmedetomidine (0...

The Cyclophilin A (CypA)/Apoptosis Inducing Factor (AIF) complex is implicated in the DNA degradation in response to various cellular stress conditions, such as oxidative stress, cerebral hypoxia-ischemia and traumatic brain injury. The pro-apoptotic form of AIF (AIF(Δ1-121)) mainly interacts with CypA through the amino acid region 370-394. The AIF(370-394) synthetic peptide inhibits complex formation in vitro by binding to CypA and exerts neuroprotection in a model of glutamate-mediated oxidative stress. Here, the binding site of AIF(Δ1-121) and AIF(370-394) on CypA has been mapped by NMR spectroscopy and biochemical studies, and a molecular model of the complex has been proposed...

RATIONALE: In the determination of immunosuppressive drugs cyclosporine A (CSA), tacrolimus (TARO), sirolimus (SIRO), and everolimus (EVE) in whole blood there is an open debate about which is the best assay between immunochemistry and liquid chromatography-tandem mass spectrometry (LC-MS/MS). This work is aimed to explore this topic, focusing on the use of updated assays and the analysis of a large number of samples. METHOD: A certified in vitro diagnostic kit coupled with a medical device LC-MS/MS was validated and applied to the analysis of 1192 blood samples of patients treated with immunosuppressive drugs...

We examined whether there is a difference in compliance between the deep and superficial conduit veins of the upper arm in response to prolonged exercise. Eight young men performed cycling exercise at 60% of peak oxygen uptake until rectal temperature had been increased by 1.1°C for 38-48 min. The cross-sectional area (CSA) of the brachial (deep) and basilic (superficial) veins was assessed by ultrasound during a cuff deflation protocol. Compliance (CPL) was calculated as the numerical derivative of the cuff pressure and CSA curve...

BACKGROUND: Total hip arthroplasty (THA) through the direct anterior approach (DAA) is known to cause less muscle damage than other surgical approaches. However, more complex primary cases, such as developmental dysplasia of the hip (DDH), might often cause muscle damage. The objective of the present study was to clarify the muscle damage observed 1 year after THA through the DAA for DDH using magnetic resonance imaging. METHODS: We prospectively compared the muscle cross-sectional area (M-CSA) and fatty atrophy (FA) in muscles by magnetic resonance imaging and the Harris hip score before and at 1-year follow-up after THA through the DAA in 3 groups: 37 patients with Crowe group 1 DDH (D1), 13 patients with Crowe group 2 and 3 DDH (D2 + 3), and 12 patients with osteonecrosis as a control...

The potential of high-field NMR to measure solid-state (95) Mo and (183) W NMR in polyoxometalates (POMs) is explored using some archetypical structures like Lindqvist, Keggin, and Dawson as model compounds that are well characterized in solution. NMR spectra in static and under magic angle spinning (MAS) were obtained, and their analysis allowed extraction of the NMR parameters, including chemical shift anisotropy (CSA) and quadrupolar coupling parameters. Despite the inherent difficulties of measurement in solid state of these low-gamma NMR nuclei, due mainly to the low spectral resolution and poor signal-to-noise ratio, the observed global trends compare well with the solution state NMR data...

Cocaine abuse induces brain injury and neurodegeneration by a mechanism that has not yet been fully elucidated. Mitochondria play a key role in cell death processes, notably through the opening of the permeability transition pore (PTP). In this work, we examined the involvement of the PTP in cocaine-induced toxicity in PC12 cell lines. We used two different PTP inhibitors -i.e. cyclosporin A (CsA) and metformin-to assess their ability to counteract the cocaine induced effects. We first observed that a 48 h exposure to cocaine strongly sensitized cells to calcium overload, as measured by the calcium retention capacity...

BACKGROUND: Despite the high prevalence of childhood sexual abuse (CSA) among men who have sex with men (MSM) and its well-documented association with substance use in adulthood, little research has examined the psychological mechanisms underlying this association. The current study utilized a large, multinational sample of MSM in Latin America to examine the role of distress intolerance (i.e., decreased capacity to withstand negative psychological states) in the relationship between childhood sexual abuse history and problematic alcohol use...
