The purpose of this study was to compare markers of hydration during sub-maximal exercise and subsequent time trial performance when consuming water (PW) or coconut water (CW). There was also a secondary aim to assess the palatability of CW during exercise and voluntary intake during intense exercise. 10 males (age 27.9 + 4.9 years, body mass 78.1 + 10.1kg, average max minute power 300.2 + 28.2W) completed 60-min of sub-maximal cycling followed by a 10-km time trial on two occasions. During these trials participants consumed either PW or CW in a randomised manner, drinking a 250 ml of the assigned drink between 10-15 min, 25-30 min and 40-45 min, and then drinking ad libitum from 55-min until the end of the time trial...

β-Conglycinin (β-CG) is well known for inducing intestinal allergies and dysfunction in neonates and young pigs. However, the underlying mechanisms are largely unknown. In this study, to clarify the role of autophagy in β-CG-induced cytotoxicity, we investigated the effects of β-CG on cell viability and autophagy activity in porcine enterocytes (IPEC-1 cells). The results indicated that the cell viability was decreased with the increasing levels of β-CG. β-CG treatment enhanced the eGFP-LC3 puncta per cells and LC3-II/LC3-I, and the latter was further increased in IPEC-1 cells cultured with bafilomycin A1...

Fluorescent DNA dyes are broadly used in many biotechnological applications for detecting and imaging DNA in cells and gels. Their binding alters the structural and nanomechanical properties of DNA and affects the biological processes that are associated with it. Although interaction modes like intercalation and minor groove binding already have been identified, associated mechanic effects like local elongation, unwinding, and softening of the DNA often remain in question. We used magnetic tweezers to quantitatively investigate the impact of three DNA-binding dyes (YOYO-1, DAPI, and DRAQ5) in a concentration-dependent manner...

Müller glia are capable of de-differentiating and proliferating to become Müller glia-derived progenitor cells (MGPCs) with the ability to regenerate retinal neurons. One of the cell-signaling pathways that drives the reprogramming of Müller glia into MGPCs in the zebrafish retina is the Jak/Stat-pathway. However, nothing is known about the influence of Jak/Stat-signaling during the formation of MGPCs in the retinas of warm-blooded vertebrates. Accordingly, we examined whether Jak/Stat-signaling influences the formation of MGPCs and differentiation of progeny in the avian retina...

Despite extensive investigations, we still do not fully understand the dynamics of the total body HIV reservoir and how sub-reservoirs in various compartments relate to one another. Studies using macaque models are enlightening but eradication strategies will still need to be tested in humans. To take the next steps in understanding and eradicating HIV reservoirs throughout the body, we propose to develop a "peri-mortem translational research model" of HIV-infected individuals (called 'The Last Gift'), which is similar to existing models in cancer research...

In this study, we sought to examine factors associated with dosing of antidepressants (ADs) in Asia. Based on reported data and clinical experience, we hypothesized that doses of ADs would be associated with demographic and clinical factors and would increase over time. This cross-sectional, pharmacoepidemiological study analyzed data collected within the Research Study on Asian Psychotropic Prescription Pattern for Antidepressants from 4164 participants in 10 Asian countries, using univariate and multivariate methods...

OBJECTIVES: Systemic sclerosis (SSc)-related digital ulcers (DU) cause significant pain and disability and are often a primary endpoint in clinical trials. However, their pathophysiology has been little studied. The objectives of this prospective study were to determine whether laser Doppler imaging (LDI) and thermography can identify ischaemic components in both fingertip and extensor surface DU and assess ulcer healing. METHODS: Patients prospectively reported new DU over a year...

Autophagy has been linked with melanoma risk and survival, but no polymorphisms in autophagy-related (ATG) genes have been investigated in relation to melanoma progression. We examined five single-nucleotide polymorphisms (SNPs) in three ATG genes (ATG5; ATG10; and ATG16L) with known or suspected impact on autophagic flux in an international population-based case-control study of melanoma. DNA from 911 melanoma patients was genotyped. An association was identified between (GG) (rs2241880) and earlier stage at diagnosis (OR 0...

The definition of a transient ischemic attack (TIA) has evolved over the past decade from a clinical diagnosis to a tissue-based definition based on neuroimaging results. TIA shares the same pathophysiology as stroke, which occurs in up to 5% of patients within 48 hours of the TIA and 10% within 90 days. This rate is decreasing, likely due to improved diagnostic and management strategies. Decision support scores have been developed to risk stratify patients, which include clinical and radiological elements...

PURPOSE: Supplementation with dietary forms of vitamin D is commonplace in clinical medicine, elite athletic cohorts and the general population, yet the response of all major vitamin D metabolites to high doses of vitamin D is poorly characterized. We aimed to identify the responses of all major vitamin D metabolites to moderate and high dose supplemental vitamin D3. METHODS: A repeated measures design was implemented in which 46 elite professional European athletes were block randomized based on their basal 25[OH]D concentration into two treatment groups...

Retinoblastoma is a pediatric eye tumor in which bi-allelic inactivation of the Retinoblastoma 1 (RB1) gene is the initiating genetic lesion. Although recently curative rates of retinoblastoma have increased, there are at this time no molecular targeted therapies available. This is, in part, due to the lack of highly penetrant and rapid retinoblastoma animal models that facilitate rapid identification of targets that allow therapeutic intervention. Different mouse models are available, all based on genetic deactivation of both Rb1 and Retinoblastoma-like 1 (Rbl1), and each showing different kinetics of retinoblastoma development...

Current marketed dry powder inhalers utilize the energy from patient inspiration to fluidize and disperse bulk powder agglomerates into respirable particles. Variations in patient inspiratory flow profiles can lead to marked differences in total lung dose (TLD), and ultimately patient outcomes for an inhaled therapeutic. The present review aims to quantitate the flow rate dependence in TLD observed for a number of drug/device combinations using a new metric termed the Q index. With this data in hand, the review explores key attributes in the design of the formulation and device that impact flow rate dependence...

Baeyer-Villiger monooxygenases (BVMOs) catalyze the oxidation of ketones to esters or lactones by utilizing molecular oxygen and a cofactor. Type I BVMOs display a strong preference for NADPH. However, for industrial purposes NADH is the preferred cofactor, as it is ten times cheaper and more stable. Thus, we created a variant of the cyclohexanone monooxygenase from Acinetobacter sp. NCIMB 9871 (CHMOAcineto), which utilizes NADH 4,200-fold better than NADPH. By combining structure analysis, sequence alignments and literature data, 21 residues in proximity of the cofactor were identified and targeted for mutagenesis...
