Adult-onset brachial plexopathy can be classified into traumatic and non-traumatic aetiologies. Traumatic brachial plexopathies can affect the pre- or postganglionic segments of the plexus. Non-traumatic brachial plexopathies may be due to neoplasia, radiotherapy, thoracic outlet syndrome and idiopathic neuralgic amyotrophy. Conventional magnetic resonance imaging (MRI) is useful to localise the area of injury or disease, and identify the likely cause. This review discusses some of the common causes of adult-onset brachial plexopathy and their imaging features on MRI...

BACKGROUND: Doctors report inadequate training and lack confidence in providing palliative care. Although palliative care training improves self-assessed competence, it is not known whether the duration of a palliative medicine (PM) posting affects the extent of improvement in confidence. OBJECTIVE: The aim of this study was to determine whether the duration of a PM posting affects the extent of improvement in doctors' confidence in various aspects of palliative care...

Osteoporosis, a systemic metabolic disease of bone, is characterized by low bone mass and altered trabecular pattern, leading to increased risk of fractures. It increases in prevalence with age, especially in postmenopausal women, and can have other secondary causes. Radiologic evaluation of osteoporosis has historically used conventional radiography, which demonstrates cortical thinning, increased radiolucency, and altered trabecular patterns, and also aids in assessing vertebral fractures. Many indexes have been devised, such as the Saville index for the degree of radiolucency, and the Genant grading system for vertebral fractures...

Previous studies have highlighted the importance of lung-draining lymph nodes in the respiratory allergic immune response, whereas the lung parenchymal immune system has been largely neglected. We describe a new in vivo model of respiratory sensitization to Blomia tropicalis, the principal asthma allergen in the tropics, in which the immune response is focused on the lung parenchyma by transfer of Th2 cells from a novel TCR transgenic mouse, specific for the major B. tropicalis allergen Blo t 5, that targets the lung rather than the draining lymph nodes...

PURPOSE: A proportion of newly diagnosed cancer patients may experience anxiety and depression. Emotion suppression has been associated with poorer psycho-emotional outcomes, while reappraisal may be an adaptive emotion regulation strategy. Few studies have examined potential mechanisms linking reappraisal to psycho-emotional outcomes in cancer patients. This study aims to replicate findings on reappraisal and suppression, and further examine if hope mediates the association between reappraisal and anxiety/depression in patients newly diagnosed with cancer...

Lead-free piezoelectric 0.5(Ba0.7Ca0.3)TiO3-0.5Ba(Zr0.2Ti0.8)O3 (BCTZ) nanoparticles (NPs) composed of earth-abundant elements were adopted for use in a flexible composite-based piezoelectric energy harvester (PEH) that can convert mechanical deformation into electrical energy. The solid-state synthesized BCTZ NPs and silver nanowires (Ag NWs) chosen to reduce the toxicity of the filler materials were blended with a polydimethylsiloxane (PDMS) matrix to produce a piezoelectric nanocomposite (p-NC). The naturally flexible polymer-based p-NC layers were sandwiched between two conductive polyethylene terephthalate plastic substrates to achieve a flexible energy harvester...

A common indication for corneal transplantation, which is the most transplanted tissue, is a dysfunctional corneal endothelium due to Fuchs' endothelial dystrophy (FED). FED is diagnosed by the presence of in vivo pathological microtopography on the Descemet membrane, which is called corneal guttata. Minimally invasive corneal endothelial cell regenerative procedures such as endothelial cell injection therapy and Rho kinase inhibitor pharmacotherapy have been proposed as alternatives to conventional corneal transplantation for FED patients...

BACKGROUND: Frailty is a measure of physiologic reserve associated with increased vulnerability to adverse outcomes following surgery in older adults. The 'accumulating deficits' model of frailty has been applied to the NSQIP database, and an 11-item modified frailty index (mFI) has been validated. We developed a condensed 5-item frailty index and used this to assess the relationship between frailty and outcomes in patients undergoing paraesophageal hernia (PEH) repair. METHODS: The NSQIP database was queried for ICD-9 and CPT codes associated with PEH repair...

Exogenous hydrogen sulfide (H2S) is known to exert anti-inflammatory effects both in macrophages and in animal models. In this study, we first showed that NaHS caused a concentration dependent reduction in TNFα and IL-6 secretion in LPS-stimulated RAW264.7 macrophages in the absence of cell death. Thereafter, we screened a series of novel slow H2S donors for similar activity. One such compound, FW1256, concentration dependently decreased TNFα, IL-6, PGE2 and NO generation in LPS-stimulated RAW264.7 macrophages and BMDMs...

Recently, post-exercise blood pressure (BP) has been considered a predictive tool to identify individuals who are responsive or not to BP reductions with exercise training (i. e., "high" and "low responders"). This study aimed to analyze the inter- and intra-individual BP responsiveness following a single bout of high-intensity interval exercise (HIIE) and continuous exercise (CE) in normotensive men (n=14; 24.5±4.2 years). Mean change in BP during the 60 min period post-exercise was analyzed and minimal detectable change (MDC) was calculated to classify the subjects as "low" (no post-exercise hypotension [PEH]) and "high responders" (PEH occurrence) following each exercise protocol (inter-individual analysis)...

Bacterial canker, caused by Xanthomonas citri subsp. citri (Xcc), is one of the most destructive diseases of citrus. The pectolytic enzymes produced by phytobacteria are important virulence factors involved in tissue maceration, electrolyte loss and cell death of host plants. In this study, the promoter activity of the pectolytic enzyme genes pel1, pel2, pel3, pglA, and peh-1 were investigated in Xcc XW19 strain using the β-glucuronidase (GUS) gene as a reporter. GUS activity expressed under the control of the pel1, pel3, pglA, and peh-1 gene promoters positively correlated with bacterial growth...

We report the design, fabrication, and testing of a photonic crystal (PC) biosensor structure that incorporates a porous high refractive index TiO2 dielectric film that enables immobilization of capture proteins within an enhanced surface-area volume that spatially overlaps with the regions of resonant electromagnetic fields where biomolecular binding can produce the greatest shifts in photonic crystal resonant wavelength. Despite the nanoscale porosity of the sensor structure, the PC slab exhibits narrowband and high efficiency resonant reflection, enabling the structure to serve as a wavelength-tunable element of an external cavity laser...

While the asymptomatic paraesophageal hernia (PEH) can be observed safely, surgery is indicated for symptomatic hernias. Laparoscopic repair is associated with decreased morbidity and mortality; however, it is associated with a higher rate of radiologic recurrence when compared with the open approach. Though a majority of patients experience good symptomatic relief from laparoscopic repair, strict adherence to good technique is critical to minimize recurrence. The fundamental steps of laparoscopic PEH repair include adequate mediastinal mobilization of the esophagus, tension-free approximation of the diaphragmatic crura, and gastric fundoplication...

Reference intervals are the most commonly used decision support tool when interpreting quantitative laboratory results. They may require partitioning to better describe subpopulations that display significantly different reference values. Partitioning by age is particularly important for the paediatric population since there are marked physiological changes associated with growth and maturation. However, most partitioning methods are either technically complex or require prior knowledge of the underlying physiology/biological variation of the population...

Evidence indicates that chronic reductions in blood pressure (BP) due to aerobic exercise depend on the ability to induce post-exercise hypotension (PEH) after each training bout. The purpose of this study was to investigate PEH after isocaloric bouts of continuous and accumulated running. 10 healthy pre-hypertensive men (aged 27.6±3.5 years) performed the following bouts of exercise: a) A continuous bout (CONT) expending a total of 400 kcal; and b) An accumulated bout split into 2×200 kcal (INTER1 and INTER2) to total 400 kcal at 75% of oxygen uptake reserve...
