AIM: Sphingosine-1-phosphate (S1P) influences resistance vessel function and is implicated in renal pathological processes. Previous studies revealed that S1P evoked potent vasoconstriction of the preglomerular microvasculature, but the underlying mechanisms remain incompletely defined. We postulated that S1P-mediated preglomerular microvascular vasoconstriction involves activation of voltage-dependent L-type calcium channels (L-VDCC) and the rho/rho kinase pathway. METHODS: Afferent arteriolar reactivity was assessed in vitro using the blood-perfused rat juxtamedullary nephron preparation and diameter was measured during exposure to physiological and pharmacological agents...

Cysteine proteases play multiple roles in basically all aspects of physiology and development. In plants, they are involved in growth and development and in accumulation and mobilization of storage proteins. Furthermore, they are engaged in signalling pathways and in the response to biotic and abiotic stresses. In animals and also in humans, they are responsible for senescence and apoptosis, prohormone processing, and ECM remodelling. When analyzed by zymography, the enzyme must be renaturated after SDS-PAGE...

Multipotent mesenchymal stromal cells (MSCs) are considered cue regulators of tissue remodelling. Their activity is strongly governed by local milieu, where O2 level is most important. The elevation of inflammatory mediators and acute O2 lowering may additionally modulate MSC activity. In present paper the priming effects of IFN-gamma on adipose tissue-derived MSCs (ASCs) at tissue-related O2 level (5%) and acute hypoxic stress (0.1% O2 ) were assessed as alterations of ASCs' CFU-F, proliferation, migration, osteo-commitment...

Galectins, a family of multifunctional glycan-binding proteins, are proposed as biomarkers of cellular stress responses. Avian migration is an energetically challenging physical stress, which represents a physiological model of muscular endurance exercises. This study assesses change in galectin gene expression profiles associated with seasonal variation in migratory state and endurance flight in yellow-rumped warblers (Setophaga coronata). Bioinformatics analysis and real-time qPCR were used to analyse the expression of galectins in flight muscle, heart and liver tissues of 15 warblers separated into three groups of winter unflown, and fall migratory flown/unflown birds...

BACKGROUND: Ex vivo lung perfusion (EVLP) has improved the process of donor lung management. Cytokine accumulation during EVLP has been shown to correlate with worse outcome after lung transplantation. Our objective in this study was to test the safety and efficacy of cytokine filtration during EVLP in a large animal model. METHODS: Pig donor lungs were preserved for 24 hours at 4°C, followed by 12 hours of EVLP, according to the Toronto protocol. The perfusate was continuously run through an absorbent device (CytoSorb) via a veno-venous shunt from the reservoir in the filter group...

India is one of the leading countries in production and indiscriminate consumption of pesticides. Owing to their xenobiotic nature, pesticides affect soil microorganisms that serve as mediators in plant growth promotion. Our study aimed to deliver a comprehensive picture, by comparing the effects of synthetic pesticides (chlorpyriphos, cypermethrin, and a combination of both) with a biopesticide (azadirachtin) at their recommended field application level (L), and three times the recommended dosage (H) on structure and function of microbial community in rhizosphere of Vigna radiata...

BACKGROUND: Research suggests that posttraumatic stress disorder (PTSD) is associated with metabolic syndrome (MetS) and that PTSD-associated MetS is related to decreased cortical thickness. However, the role of genetic factors in these associations is unclear. This study evaluated contributions of polygenic obesity risk and PTSD to MetS and of MetS and polygenic obesity risk to cortical thickness. METHODS: 196 white, non-Hispanic veterans of the wars in Iraq and Afghanistan underwent clinical diagnostic interviews, physiological assessments, and genome-wide genotyping; 168 also completed magnetic resonance imaging scans...

The nutrition transition promotes the development of childhood obesity. Currently, Mexico is affected by this serious public health problem. The nutritional and functional characterization of a whole menu has a number of advantages over the study of single nutrients. Since breakfast is considered the most important meal of the day, this study aimed to evaluate the metabolite profile produced by in vitro human colonic fermentation of the isolated indigestible fraction (IF) from three different Mexican breakfast (M-B) menus (Modified "MM-B", traditional "TM-B", and alternative "AM-B"), previously identified as commonly consumed by Mexican schoolchildren in Nayarit State, Mexico...

The performance of Olympic distance cross-country mountain bikers (XCO-MTB) is affected by constraints such as erosion of track surfaces and mass start congestion which can affect race results. Standardised laboratory assessments quantify inter-seasonal and intra-seasonal cycling potential through the assessment of multiple physiological capacities. Therefore, this study examined whether the power profile assessment could discriminate between competitive XCO-MTB and non-competitive mountain bikers (NC-MTB)...

Reprimo (RPRM), a member of the RPRM gene family, is a tumor-suppressor gene involved in the regulation of the p53-mediated cell cycle arrest at G2/M. RPRM has been associated with malignant tumor progression and proposed as a potential biomarker for early cancer detection. However, the expression and role of RPRM, as well as its family, are poorly understood and their physiology is as yet unstudied. In this scenario, a model system like the zebrafish could serve to dissect the role of the RPRM family members in vivo...

With a constantly growing portion of elderly within our population and the advances of modern medicine, surgery on aged and very aged patients has become a daily hospital routine. Due to the physical and mental features of ageing these patients face special perioperative risks. They display a higher rate of complications, morbidity and cognitive deficits which might in the end lead to persisting need of care. Even in the healthy elderly, most organ functions are "physiologically" instable or deficient and the homeostasis of health and disease is fragile...

Recent studies of animal personality have focused on its proximate causation and ecological and evolutionary significance in particular, but the question of its development was largely overlooked. The attributes of personality are defined as between-individual differences in behaviour, which are consistent over time (differential consistency) and contexts (contextual generality) and both can be affected by development. We assessed several candidates for personality variables measured in various tests with different contexts over several life-stages (juveniles, older juveniles, subadults and adults) in the Northern common boa...

This article reviews pharmacokinetic (PK) and pharmacodynamic (PD) concepts relating to the pharmacology of basal insulin analogs. Understanding the pharmacology of currently available long-acting basal insulins and the techniques used to assess PK and PD parameters (e.g. the euglycemic clamp method) is important when considering the efficacy and safety of these agents, and can help in understanding the rationale for specific dosing strategies when tailoring therapy for a specific patient. Basal insulins such as insulin glargine 100 units (U)/mL and insulin detemir show improved PK/PD characteristics compared with the intermediate-acting NPH insulin, with a longer duration of action, a more consistent glucose-lowering effect and less prominent concentration peaks...
