Although appropriate exercise is beneficial for enhancing brain functions, high-intensity exercise (HIE)-induced cognitive dysfunction is causing more and more concerns nowadays. In the present study, we observed the effects of high-intensity treadmill running on the spatial learning of the adult Sprague Dawley male rats in Y-maze (n = 16 per group), and investigated its possible electrophysiological and molecular mechanisms by examining in vivo hippocampal long-term potentiation (LTP), central inflammatory responses, and JNK/p38/ERK signal pathway...

BACKGROUND: Hyper-IgE syndrome (HIES) due to DOCK8 deficiency is an autosomal recessive (AR) primary combined immunodeficiency which results in significant morbidity and mortality at a young age. Different mutations in the DOCK8 gene can lead to variable severity of the disease. OBJECTIVE: We evaluated the genetic mutations in three related patients with severe clinical manifestations suggestive of AR HIES. We also explored whether treatment with stem cell transplantation could lead to complete disease resolution...

Relapsing polychondritis (RP) is a very rare autoimmune disease characterised by a relapsing inflammation of the cartilaginous tissues (joints, ears, nose, intervertebral discs, larynx, trachea and cartilaginous bronchi), which may progress to long-lasting atrophy and/or deformity of the cartilages. Non-cartilaginous tissues may also be affected, such as the eyes, heart, aorta, inner ear and skin. RP has a long and unpredictable course. Because no randomised therapeutic trials are available, the treatment of RP remains mainly empirical...

BACKGROUND: Birth asphyxia is the fifth major cause of under-five child deaths after pneumonia, diarrhoea, neonatal infections and complications of preterm birth. It is one of the important causes of neonatal mortality and morbidity accounting up to 30% of neonatal death in Nepal. It is also an important cause of long-term neurological disability and impairment. The mortality rate due to birth asphyxia is considered a good guide to the quality of perinatal care. This study was conducted to assess the rate of birth asphyxia, risk factors and outcome of the babies who were asphyxiated at birth...

Neurological localizations of sarcoidosis are heterogeneous and may affect virtually every part of the central or peripheral nervous system. They are often the inaugural manifestation of sarcoidosis. The diagnosis may be difficult due to the lack of extra-neurological localization. Diagnosis may be discussed in the presence of an inflammatory neurological disease, in particular in case of suggestive radiological or biological pattern. Cerebrospinal fluid analysis shows lymphocytic pleiocytosis, often with low glucose level...

Brain damage following a perinatal hypoxic-ischemic encephalopathy (HIE) can be diagnosed by different techniques. The aim of the present study was to combine magnetic resonance (MR) imaging with proton MR spectroscopy in HIE diagnosis and to evaluate their correlation with outcome. A prospective observational cohort study was performed between February 2012 and February 2013. Consecutive newborns, 24 full-term neonates with HIE (mild to moderate and severe group) and 5 normal neonates, were included. Two sequential MR studies were performed; a conventional MR imaging for observation in T1 weighted image (WI) and T2WI, and proton MR spectroscopy for observation in the left or right basal ganglia and thalamus...

To determine the optimal time window for MR imaging with quantitative ADC measurement in neonatal HIE after hypothermia treatment, a retrospective review was performed on consecutive hypothermia-treated term neonates with HIE, with an initial and follow-up MR imaging within the first two weeks of life. Three neuroradiologists categorized each set of MR imaging as normal, mild, moderate or severe HIE based on a consensus review of the serial imaging. The lowest ADC values from the white matter, corpus callosum, and basal ganglia/thalamus were measured...

A new synthetic route to the Tau binder, THK-523, is disclosed herein, which can easily be adapted to (13) C- and D-isotope labeling. The synthesis proceeds via two key reactions, namely, a Pd-catalyzed carbonylative Sonogashira coupling and a reductive ring-closing step with hydrogen or deuterium gas. By carrying out these reactions in a 2-chamber reactor we reported previously, ex situ-generated carbon monoxide and hydrogen/deuterium can be applied in stoichiometric quantities, thereby facilitating isotope labeling of this Tau-binding compound...

OBJECTIVE: In Western medicine, hie (cold sensation) is thought as a subjective complaint. Consequently, despite women's complaints of health problems due to hie, such as distress and decreased quality of life, it is not diagnosed as a disease or given active treatment. However, hie sometimes requires emergency treatment or is a symptom of other disorders. Thus, diagnosing hie and eliminating distress due to hie are clinically significant. This research aimed to discriminate between hie and hiesho (cold disorder) and quantify hie by using objective assessments in addition to subjective assessments...

BACKGROUND/OBJECTIVES: Advance care planning (ACP) is an iterative, complex, and dynamic process of discussion, decision-making, and documentation about end-of-life care. The extent to which this process takes place in older adults in diverse socioeconomic settings is not well documented. The aim of this study was to assess the knowledge, attitudes, and beliefs about ACP among older adults in two socioeconomically diverse settings to identify the individual and contextual factors that influence behaviors regarding end-of-life care...

Recent studies have demonstrated that amides can be used in nickel-catalyzed reactions that lead to cleavage of the amide C-N bond, with formation of a C-C or C-heteroatom bond. However, the general scope of these methodologies has been restricted to amides where the carbonyl is directly attached to an arene or heteroarene. We now report the nickel-catalyzed esterification of amides derived from aliphatic carboxylic acids. The transformation requires only a slight excess of the alcohol nucleophile and is tolerant of heterocycles, substrates with epimerizable stereocenters, and sterically congested coupling partners...

Hypoxic-ischemic encephalopathy (HIE) is a recognizable and defined clinical syndrome in term infants that results from a severe or prolonged hypoxic-ischemic episode before or during birth. However, in the preterm infant, defining hypoxic-ischemic injury (HII), its clinical course, monitoring, and outcomes remains complex. Few studies examine preterm HIE, and these are heterogeneous, with variable inclusion criteria and outcomes reported. We examine the available evidence that implies that the incidence of hypoxic-ischemic insult in preterm infants is probably higher than recognized and follows a more complex clinical course, with higher rates of adverse neurological outcomes, compared to term infants...

Time reversal acoustics (TRA) has gained widespread applications for communication and measurements. In general, a scattering medium in combination with multiple transducers is needed to achieve a sufficiently large acoustical aperture. In this paper, we report an implementation for a cost-effective and compact time reversal emitter-receiver driven by a single piezoelectric element. It is based on a leaky cavity with random 3-dimensional printed surfaces. The random surfaces greatly increase the spatio-temporal focusing quality as compared to flat surfaces and allow the focus of an acoustic beam to be steered over an angle of 41°...
