Methylene-tetrahydrofolate reductase (MTHFR) and paraoxonase 1 (PON1) gene polymorphisms have been associated with hyperhomocysteinemia and oxidative stress increase, that are established cardiovascular risk factors. Given that intense physical activity may increase the susceptibility to adverse cardiovascular outcomes, here we investigated the effects of MTHFR C677T and A1298C as well as PON1 Q192R gene polymorphisms on cardiovascular risk markers in twenty-eight male water polo elite players. The mean plasma levels of homocysteine (Hcy) and advanced oxidation protein products (AOPP) were above reference limits in resting conditions, and increased after competition...

The understanding of roles of bZIP factors in biological processes during plant development and under abiotic stresses requires the detailed mechanistic knowledge of behaviour of TFs. Basic leucine zipper (bZIP) transcription factors (TFs) play key roles in the regulation of grain development and plant responses to abiotic stresses. We investigated the role and molecular mechanisms of function of the TabZIP2 gene isolated from drought-stressed wheat plants. Molecular characterisation of TabZIP2 and derived protein included analyses of gene expression and its target promoter, and the influence of interacting partners on the target promoter activation...

Male Stress Urinary Incontinence is a complication post robotic radical prostatectomy. This is a major problem that needs to be solved, since it has great impact on quality of life affecting the patient's physical activity and social well-being. A systematic review relating to literature on impact of preoperative PFE on continence outcomes for patients undergoing prostatectomy was conducted. The search strategy aimed to identify all references related to pelvic floor exercises and post-prostatectomy. Search terms used were as follows: (Pelvic floor exercises) AND (incontinence) AND (prostatectomy)...

Worldwide there are over 46 million people living with dementia, and this number is expected to double every 20 years reaching about 131 million by 2050. The cost to the community and government health systems, as well as the stress on families and carers is incalculable. Over three decades of research into this disease have been undertaken by several research groups in Australia, including work by our original research group in Western Australia which was involved in the discovery and sequencing of the amyloid-β peptide (also known as Aβ or A4 peptide) extracted from cerebral amyloid plaques...

Phenylpropanoids including diverse compounds, such as monolignols and hydroxycinnamic acids (HCAAs), are essential for land plants to protect them against abiotic stresses, and create physical and chemical barriers to pathogen infection. However, the production control of these compounds against to pathogens has been poorly understood. Previously we showed that a MAMP (microbe-associated molecular pattern) -responsive MAPK (mitogen-activated protein kinase) cascade (MKK4-MPK3/MPK6) comprehensively induced the expression of cinnamate/monolignol synthesis genes in rice cells...

Type II toxin-antitoxin (TA) systems play important roles in bacterial stress survival by regulating cell growth or death. They are highly abundant in cyanobacteria yet remain poorly characterized. Here, we report the identification and regulation of a putative type II TA system from Synechocystis PCC6803, VapBC15. The VapBC15 system is encoded by the chromosomal operon vapBC15 . Exogenous expression of VapC15 dramatically arrested cell growth of Escherichia coli and reduced the numbers of colony-forming units (CFU)...

Real-world stressors are complex and multimodal, involving physical, psychological, and social dimensions. However, the brain networks that mediate stress responses to these stimuli need to be further studied. We used c-Fos mapping in mice to characterize brain circuits activated by exposure to a single episode of multimodal stress (MMS), and compared these to circuits activated by electric foot shocks (EFS). We focused on characterizing c-Fos activity in stress-relevant brain regions including the paraventricular nucleus (PVN) of the hypothalamus and the bed nucleus of the stria terminalis (BNST)...

AHCC® is a functional food from the basidiomycete Lentinula edodes. We evaluated the effects of AHCC® on subjects under different kinds of stress and at rest. Physical stress was imposed using an active standing test, known as Schellong's test. Sympathetic nervous activity in the standing position was significantly greater in AHCC®-treated subjects than in a placebo group. In contrast, AHCC® significantly increased parasympathetic nervous activity at rest. Under mental stress, AHCC® increased sympathetic nervous activity, with no difference in the parasympathetic nervous system...

BACKGROUND: The rising population of older adults is transforming Taiwan society. Although many long-term care facilities now operate for older adults, the transition from the home environment to long-term facilities may cause multiple issues, including relocation stress syndrome, for new residents. Autonomy is a critical element of the human experience. Leisure, as an expression of autonomy, has been shown to enhance self-image and promote feelings of competence and mastery. PURPOSE: The aim of this study was to assess the relationship between participation in leisure activities and adjustment to residential care using the continuity theory...

BACKGROUND: Migraineurs have a high prevalence of neck pain prior to or during headache attacks. Whether neck pain is a symptom of migraine or an indicator for a constant neck muscle dysfunction potentially triggering migraine attacks is a topic of scientific debate. The presence of myofascial trigger points in neck muscles including the trapezius muscle, points towards muscle alterations associated with migraine. We measured electromyography (EMG) of the neck muscles in a large cohort to identify whether neck pain and neckmuscle tension reported by migraine patients can be attributed to increased neck muscle activation during rest, mental stress or physical activity...

One central goal of mechanobiology is to understand the reciprocal effect of mechanical stress on proteins and cells. Despite its importance, the influence of mechanical stress on cellular function is still poorly understood. In part, this knowledge gap exists because few tools enable simultaneous deformation of tissue and cells, imaging of cellular activity in live animals, and efficient restriction of motility in otherwise highly mobile model organisms, such as the nematode Caenorhabditis elegans. The small size of C...

Amperometry recording of cells subjected to osmotic shock show that secretory cells respond to this physical stress by reducing the exocytosis activity and the amount of neurotransmitter released from vesicles in single exocytosis events. It has been suggested that the reduction in neurotransmitters expelled is due to alterations in membrane biophysical properties when cells shrink in response to osmotic stress and with assumptions made that secretory vesicles in the cell cytoplasm are not affected by extracellular osmotic stress...

INTRODUCTION AND HYPOTHESIS: People are increasingly aware of healthy lifestyles. Extenuating practice can injure the pelvic floor. Urinary incontinence (UI) is a prevalent condition in women whether they exercise professionally or not. The most common symptom is stress UI. It is reported in a large variety of sports and may interfere with everyday life or training, leading athletes to change or compromise their performance or risk compromising it. We aimed to assess the prevalence of UI in female athletes and to determine whether the type of sport might also influence UI...

PURPOSE OF REVIEW: The formation of a hierarchical vascular network is a complex process that requires precise temporal and spatial integration of several signaling pathways. Amongst those, Notch has emerged as a key regulator of multiple steps that expand from endothelial sprouting to arterial specification and remains relevant in the adult. This review aims to summarize major concepts and rising hypotheses on the role of Notch signaling in the endothelium. RECENT FINDINGS: A wealth of new information has helped to clarify how Notch signaling cooperates with other pathways to orchestrate vascular morphogenesis, branching, and function...
