Inhaled nitric monoxide (iNO) is increasingly used as a medical treatment for acute respiratory distress syndrome. A course of the existing nitric monoxide (NO) therapy with gas cylinders could cost up to approximately $15,000 for an average of 30.2 h. Moreover, a gas cylinder containing a mixture of N2 and NO may potentially leak NO. The objective of this study is to develop an efficient and cost-effective on-site iNO generation system. In the present setup, NO was generated by using dry air or mixed oxygen/nitrogen (O2/N2) and an AC power source with an output power level of 5-30 W at atmospheric pressure...

The transcription factors CREB (cAMP Response Element Binding factor), SRF (Serum Response Factor) and MEF2 (Myocyte Enhancer Factor 2) play critical roles in the mechanisms underlying neuronal plasticity. However, the role of the activation of these transcription factors in the different components of plasticity in vivo is not well known. In this study, we tested the role of CREB, SRF and MEF2 in ocular dominance plasticity (ODP), a paradigm of activity-dependent neuronal plasticity in the visual cortex. These three proteins bind to the Synaptic Activity Response Element (SARE), an enhancer sequence found upstream of many plasticity-related genes (Kawashima et al...

Adiponectin regulates glucose and lipid metabolism, acting against atherosclerosis and metabolic syndrome. Accumulating evidences suggest that adiponectin acts on the brain including the arcuate nucleus of hypothalamus (ARC). The ARC contains orexigenic neuropeptide Y (NPY)/agouti related peptide (AgRP) neurons and anorexigenic proopiomelanocortin (POMC) neurons, the first order neurons for feeding regulation. We recently reported that intracerebroventricular injection of adiponectin at low glucose level suppressed food intake, while at elevated glucose level it promoted food intake, exhibiting glucose-dependent reciprocal effects...

BACKGROUND: Subacromial impingement syndrome (SAIS) is characterized by pain experienced through an arc of elevation as the shoulder abducts and diagnosed commonly by Neer test (NT). However, the diagnostic accuracy of NT for SAIS is still limited. Here, a modified Neer test (MNT) was introduced to improve the accuracy of the clinical examination in diagnosing SAIS and differentiating it from frozen shoulder. The aim of this study was to investigate the diagnostic values of MNT in diagnosing SAIS and differentiating it from frozen shoulder...

BACKGROUND: Lipid-rich plaque (LRP) is thought to be a precursor to cardiac events. However, its clinical significance in coronary arteries has never been systematically investigated. OBJECTIVES: This study investigated the prevalence and clinical significance of LRP in the nonculprit region of the target vessel in patients undergoing percutaneous coronary intervention (PCI). METHODS: The study included 1,474 patients from 20 sites across 6 countries undergoing PCI, who had optical coherence tomography (OCT) imaging of the target vessel...

Foot orthoses are often used to correct altered gait patterns. The purpose of this study was to investigate how foot orthoses can modify the magnitude of three dimensional moments of ankle, knee, and hip joints during a stride of gait in children with flexible flat feet. Bilateral gait data were collected from fourteen male children (age 10.2±1.4 years) suffering from flat feet syndrome. In order to obtain the kinematics data, a Vicon system with six cameras (100Hz) was used and two Kistler force plates (1000Hz) to record the kinetics data under each leg...

Paul D Blanc
The history of the biomedical recognition manganese-caused neurotoxicity mirrors changing technologies as much as it does the ontology of parkinsonism. The initial 1837 report of manganese-induced neurologic injury was made by John Couper, a university-based physician in Scotland. He made clear that the outbreak occurred among workers at the Charles Tennant bleach manufactory in the environs of Glasgow. The relatively new technology of chlorine generation using manganese accounted for the novel exposure involved...

BACKGROUND: We hypothesize that surgery for moderate-to-severe camptodactyly (>50 degrees) results in modest gains in range of motion and improved digital position. METHODS: A retrospective analysis of patients undergoing surgery for camptodactyly at a tertiary children's hospital between 2000 and 2014 was performed. Surgery was indicated for patients with persistent, functionally limiting flexion contractures despite observation, therapy, and splinting. Data were collected on demographics, clinical history and presentation, nonoperative management, surgery, and clinical follow-up, focusing on range of motion at the involved joint...

Platelets are critical to hemostasis and thrombosis. Upon detecting injury, platelets show a range of responses including the release of protein cargo from α-granules. This cargo is synthesized by platelet precursor megakaryocytes or endocytosed by megakaryocytes and/or platelets. Insights into α-granule biogenesis have come from studies of hereditary conditions where these granules are immature, deficient or absent. Studies of Arthrogryposis, Renal dysfunction, and Cholestasis (ARC) syndrome identified the first proteins essential to α-granule biogenesis: VPS33B and VPS16B...

Down syndrome (DS) is the leading chromosomal cause of intellectual disability, yet the neural substrates of learning and memory deficits remain poorly understood. Here, we interrogate neural networks linked to learning and memory in a well-characterized model of DS, the Ts65Dn mouse. We report that Ts65Dn mice exhibit exploratory behavior that is not different from littermate wild-type (WT) controls yet behavioral activation of Arc mRNA transcription in pyramidal neurons of the CA1 region of the hippocampus is altered in Ts65Dn mice...

AbstractZambia and other sub-Saharan nations suffer from a critical shortage of trained health-care professionals to combat the human immunodeficiency virus/acquired immunodeficiency syndrome crisis. The University of Maryland and the Zambian Ministry of Health have partnered over the past decade to develop health-care capacity among physicians, nurses, and community health workers. We describe novel interventions to train health-care workers at all levels and argue that our collaboration represents a successful model for such partnerships between western medical institutions and African governmental health agencies...

BACKGROUND: Neuropathic symptoms after median nerve repair at the wrist or secondary to refractory carpal tunnel syndrome may become debilitating. These symptoms develop because of perineural adhesions, intraneural fibrosis, and fixation of the nerve to the transverse carpal ligament after surgery, and often require neurolysis. Interposition of vascularized soft tissue over the median nerve at the time of neurolysis prevents recurrence of such adhesions. The synovial flap, fashioned from the synovial lining of the flexor tendon sheath, is an ideal tissue for this purpose...

ARC syndrome (arthrogryposis - renal dysfunction - cholestasis) is a rare lethal multisystemic autosomal recessive disease. A newborn of consanguineous parents of Algerian descent presented cholestatic jaundice, dehydration, and Fanconi syndrome at 10 days of life. The blood smear showed a very characteristic gray appearance of platelets. A homozygous mutation was evidenced in the VPS33B gene. This gene codes for a protein involved in trafficking of intracellular vesicles. The mutation (c.604-2A>G) present in the heterozygous state in the parents affects an invariant base of the splice acceptor site and to our knowledge has not been reported yet...

CGG repeats in the 5'UTR of Fragile X Mental Retardation 1 (FMR1) RNA mediate RNA localization and translation in granules. Large expansions of CGG repeats (> 200 repeats) in FMR1, referred to as full mutations, are associated with fragile X syndrome (FXS). Smaller expansions (55-200 repeats), referred to as premutations, are associated with fragile X tremor ataxia syndrome (FXTAS) and fragile X premature ovarian insufficiency (FXPOI). TMPyP4 is a porphyrin ring compound that destabilizes CGG repeat RNA secondary structure...

Multiple loss-of-function mutations in TRIAD3 (a.k.a. RNF216) have recently been identified in patients suffering from Gordon Holmes syndrome (GHS), characterized by cognitive decline, dementia, and movement disorders. TRIAD3A is an E3 ubiquitin ligase that recognizes and facilitates the ubiquitination of its target for degradation by the ubiquitin-proteasome system (UPS). Here, we demonstrate that two of these missense substitutions in TRIAD3 (R660C and R694C) could not regulate the degradation of their neuronal target, activity-regulated cytoskeletal-associated protein (Arc/Arg 3...

Hyperandrogenism, disturbance of the hypothalamus-pituitary-ovary axis followed by elevated serum luteinizing hormone (LH) levels, and insulin resistance are involved in the complicated pathophysiology of polycystic ovary syndrome (PCOS). Kisspeptin is coexpressed with neurokinin B (NKB) in the arcuate nucleus (ARC), the center of the gonadotropin-releasing hormone pulse generator that is responsible for pulsatile LH secretion. We compared 2 androgenized rat models of PCOS to evaluate the estrous cycle, hormonal profiles, and expression of kisspeptin and NKB in the ARC...
