Candida lipolytica candidemia is a rare but an emerging pathogenic yeast infection in humans. It can gain access to the bloodstream through intravascular catheterization, especially through central venous catheters in immunocompromised or critically ill patients during hospitalization. In this report, we present a noncatheter-related C. lipolytica candidemia infection in an ...

Aging is usually associated with a progressive disruption of the redox balance leading to recurrent damage resulting from oxidative stress. Oxidative stress resulting from excessive free-radical release is likely implicated in the initiation and progression of motor behavior disorders. Therefore, antioxidant therapies have received considerable attention in motor behavior defects ...

Anorexia deteriorates the quality of life in patients with anorexia nervosa, stress disorders, gastrointestinal disorders, and cancer. Pro-opiomelanocortin (POMC) neurons in the hypothalamic arcuate nucleus (ARC), serotonin (5-HT) and its 2C receptor (5-HT2CR) are implicated in anorexia. Rikkunshito, a traditional Japanese medicine, has been used to treat anorexia and gastrointestinal ...

Cannabinoid system plays a pivotal role in the seizure threshold modulation which is mainly mediated through activation of the cannabinoid CB1 receptor. There is also several evidence of interaction between cannabinoid system and α2-adrenoceptors in different paradigms. Using model of clonic seizure induced by intravenous pentylenetetrazole (PTZ) in male mice, ...

The discovery of induced pluripotent stem cell (iPSC) technology has raised hopes in circumventing the current limitations in cell-based therapies where autologous stem cells could be generated from terminally differentiated somatic cells. Given the relatively short history of iPSC research, most of the studies are scientific exploratory in nature and ...

BACKGROUND: TRPC6 has been proposed to be responsible for the abnormal OAG-dependent Ca(2+) influx in cystic fibrosis (CF) cells and we hypothesized that it interacts with CFTR. Here, we investigated how this functional complex operates in CF and non-CF epithelial cells. METHODS: Chinese hamster ovary (CHO) cells stably transfected with ...

Breast cancer is linked to hyperactivation of protein tyrosine kinases (PTKs), and recent studies have unveiled that selective tyrosine dephosphorylation by protein tyrosine phosphatases (PTPs) of specific substrates, including PTKs, may activate or inactivate oncogenic pathways in human breast cancer cell growth-related processes. Here, we review the current knowledge on ...

Controversy persists as to whether the acquisition of beneficial metabolic functions via endosymbiosis can occur suddenly on an evolutionary time scale. In this study, an early stage of endosymbiotic associations, which evolved from previously unassociated auto (photo)- and heterotrophic unicellular organisms was analyzed using an experimental ecosystem model, called CET ...

Epigenetics has been gaining great attention as a therapeutic target in cancer. The cancer genome usually contains both hyper- and hypo-methylated genes to increase invasion, proliferation and metastasis. These cells not only operate their own growth, but also develop various strategies to escape from immune surveillance, and for this aim, ...

Dendritic cells (DCs) play an important role in inducing immune tolerance. Inhibitory receptors, such as ILT2/CD85j, are involved in the tolerogenic effect of DCs and previous studies have indicated the important role of these receptors on the pathogenesis of autoimmune diseases. The aim of this study was to evaluate the ...

Nonribosomal peptide synthetases (NRPS) are large modular macromolecular machines that produce small peptide molecules with wide-ranging biological activities, such as antibiotics and green chemicals. The condensation (C) domain is responsible for amide bond formation, the central chemical step in nonribosomal peptide synthesis. Here we present two crystal structures of the ...

Neuropeptide Y (NPY) is a potent orexigenic neuropeptide implicated in appetite regulation in mammals. However, except for teleost fish such as the goldfish and zebrafish, the involvement of NPY in the regulation of feeding in non-mammalian vertebrates has not been well studied. Anuran amphibian larvae feed and grow during the ...

Closed-loop insulin delivery systems often implement glucose measurement and insulin administration in the subcutis. However some existing models for glucose-insulin system ignored the dynamics of subcutaneous glucose and subcutaneously-injected insulin. This paper reports a two-compartment model that includes glucose and insulin dynamics in subcutis, and its evaluation using patient data. ...

Efficient dynamic interactions among cofactor, enzymes and substrate molecules are of primary importance for multi-step enzymatic reactions with in situ cofactor regeneration. Here we showed for the first time that the above dynamic interactions could be significantly intensified by exerting an external alternating magnetic field on magnetic nanoparticles-supported multi-enzymatic system ...

Inherited loss-of-function mutations in the Rim15p-mediated stress-response pathway contribute to the high fermentation rate of sake yeast strains. In the present study, we found that disruption of the RIM15 gene in ethanol-producing Saccharomyces cerevisiae strain PE-2 accelerated molasses fermentation through enhanced sucrose utilization following glucose starvation.

Prior work has repeatedly demonstrated that people who have current major depression exhibit blunted cardiovascular reactivity to acute stressors (e.g., Salomon, et al. 2009). A key question regards the psychobiological basis for these deficits, including whether such deficits are depressed mood-state dependent or whether these effects are trait-like and are ...

The second messenger cyclic guanosine monophosphat (cGMP) mediates the physiological effects of nitric oxide and natriuretic peptides in a broad spectrum of tissues and cells. So far, the major focus of research on cGMP lay on the cardiovascular system. Recent evidence suggests that cGMP also plays a major role in ...

Pediatric traumatic brain injury (TBI) may result in long-lasting language impairments alongside dysarthria, a motor-speech disorder. Whether this co-morbidity is due to the functional links between speech and language networks, or to widespread damage affecting both motor and language tracts, remains unknown. Here we investigated language function and diffusion metrics ...

INTRODUCTION:: Intravenous (IV) recombinant tissue plasminogen activator (rt-PA) is the standard of care for patients exhibiting signs of acute ischemic stroke. IV rt-PA uses weight-based dosing, and often an estimated weight is used. The clinical effects of using estimated weight in dosing IV rt-PA remain unclear. The goal of this ...

Onychophagia is defined as chronic nail biting behaviour, which usually starts during childhood. Onychotillomania results from recurrent picking and manicuring of the fingernails and/or toenails, leading to visual shortening and/or estraction of nails. The aim of this study was to assess the prevalence of onychophagia and onychotillomania in young adults, ...

Concerns over data quality impede the use of public biodiversity databases and subsequent benefits to society. Data publication could follow the well-established publication process: with automated quality checks, peer review, and editorial decisions. This would improve data accuracy, reduce the need for users to 'clean' the data, and might increase ...

Human-induced rapid environmental change (HIREC; e.g., climate change or exotic species) has caused global species declines. Although behavioral plasticity has buffered some species against HIREC, maladaptive behavioral scenarios called 'evolutionary traps' are increasingly common, threatening the persistence of affected species. Here, we review examples of evolutionary traps to identify their ...

Although correlations have frequently been observed between specific physiological and behavioural traits across a range of animal taxa, the nature of these associations has been shown to vary. Here we argue that a major source of this inconsistency is the influence of environmental stressors, which seem capable of revealing, masking, ...
