Cerebral tissue oxygenation (oxygen tension, pO2) is a critical parameter that is closely linked to brain metabolism, function, and pathophysiology. In this work, we have used electron paramagnetic resonance oximetry with a deep-tissue multi-site oxygen-sensing probe, called implantable resonator, to monitor temporal changes in cerebral pO2 simultaneously at four sites in a rabbit model of ischemic stroke induced by embolic clot. The pO2 values in healthy brain were not significantly different among the four sites measured over a period of 4 weeks...

Behavioral interventions are increasingly based on holistic approaches to health with an understanding that health-related behaviors are linked. A motivating example is provided by the Philani study, an intervention trial conducted to improve the health of South African mothers and their children. Inter-related health problems around maternal alcohol use, malnutrition, and HIV were addressed; multiple endpoints were targeted. The traditional hypothesis testing paradigm that tests significance on one primary outcome did not suffice...

BACKGROUND: Providing patient-centered healthcare requires that patient needs, preferences, and valued outcomes are more fully integrated into all decisions. Patient reported outcome measures (PROs) provide unique information from the patient perspective on overall health, symptoms, burden, and treatment response. OBJECTIVE: We sought to describe applications of PROs in clinical settings and considerations for implementation from the perspectives of PRO researchers, clinicians, administrators, policy makers, and patients attending a multidisciplinary meeting...

The effects of pH, cations (Na(+), K(+), Mg(2+), Ca(2+) and Al(3+)), and anions (Cl(-), HCO3(-), HPO4(2-) and SO4(2-)) on graphene oxide (GO) stability were investigated to address the current limitations in the knowledge regarding the stability of GO in natural surface water and its underlying mechanism. The threshold values of cations that destabilize GO were obtained and affected by both pH and anions. By employing elemental mapping and studying the effects of polyacrylic acid (PAA) on GO sedimentation and the re-dispersion of GO aggregates, we find that the GO aggregates induced by Na(+) and K(+) via electric double layer suppression and by Ca(2+) and Al(3+) via strong complxing are difficult to re-disperse completely...

Isoxsuprine hydrochloride (vasodilator drug), folic acid and ascorbic acid are medicines which can be utilized alone or simultaneously by pregnant women. In the present work the competitive binding of isoxsuprine hydrochloride (ISO) with human serum albumin (HSA) in the absence and presence of folic acid (FOL) and ascorbic acid (AS) was investigated using different spectroscopic probes and molecular docking studies. The results of fluorescence suggested that isoxsuprine alone or in the presence of ascorbic acid can bind to HSA and quench the fluorescence of HSA with static mechanism but For HSA-folic acid-isoxsuprine system, dynamic type of quenching mechanisms is involved...

The UK has adopted a broader approach to the introduction of Environmental Quality Standard (EQS) for the aquatic environment than many other jurisdictions around the world, with a greater focus on the implementation of scientifically derived standards. This follows the publication of a report by the Royal Commission on Environmental Pollution in 1998 which drew attention to the need to recognise that whilst an EQS is often just viewed as a numerical value, it also has other important characteristics that need to be recognised if it is to be a practical and effective regulatory tool...

Interferon-alpha (IFN-α) is a potent anti-viral cytokine, critical to the host immune response against viruses. IFN-α is first produced upon viral detection by pathogen recognition receptors. Following its expression, IFN-α embarks upon a complex downstream signalling cascade called the JAK/STAT pathway. This signalling pathway results in the expression of hundreds of effector genes known as interferon stimulated genes (ISGs). These genes are the basis for an elaborate effector mechanism and ultimately, the clearance of viral infection...

Social housing of rhesus macaques (Macaca mulatta) is considered to be the cornerstone of behavioral management programs in biomedical facilities. However, it also involves the risk of socially inflicted trauma. The ability to avoid such trauma would contribute to the animals' well-being and alleviate staff's concerns, thus paving the path for more introductions. Here, we sought to address the conflict between the need to socially house rhesus macaques and the need to bring social wounding to a minimum by identifying behaviors expressed early in social introductions, that may serve as predictors of later wounding events...

Studies show that if quality of healthcare in a country is to be achieved, due consideration must be given to the importance of the core cultural values as a critical factor in improving patient safety outcomes. The influence of Bhutan's traditional (core) cultural values on the attitudes and behaviours of healthcare professionals regarding patient care are not known. This study aimed to explore the possible influence of Bhutan's traditional cultural values on staff attitudes towards patient safety and quality care...

Optical fiber technology is found in a wide variety of applications to flexibly relay light between two points, enabling information transfer across long distances and allowing access to hard-to-reach areas. Large-core optical fibers and light guides find frequent use in illumination and spectroscopic applications, for example, endoscopy and high-resolution astronomical spectroscopy. Proper alignment is critical for maximizing throughput in optical fiber coupling systems; however, there currently are no formal approaches to tolerancing the alignment of a light-guide coupling system...

Bone biopsy is currently the only means to accurately assess renal osteodystrophy and responses to therapeutic interventions. With sedation, the technique is relatively painless, and complications are uncommon. Bone biopsy should be considered when the aetiology of symptoms or biochemical abnormalities is in question, and results may lead to changes in therapy. Although it remains prudent to use antiresorptive drugs cautiously in patients with chronic kidney disease (CKD) stages 3a-4 and low bone mineral density, bone biopsy may not be warranted before commencing therapy in these patients...
