It has been suggested that the predilection of sarcoidosis to affect scars is due to the presence of antigens or foreign bodies that can serve as a stimulus for granuloma formation. Several patients with sarcoidosis-specific skin lesions in venous puncture sites have been reported. However, in these patients the pathogenesis of the cutaneous lesions is not clear because the presence of foreign bodies is not to be expected. Our objective was to describe 3 patients who developed specific lesions of sarcoidosis in areas of venipuncture and to discuss their possible pathogenesis...

AIM: To analyze cytokines as biomarkers for evaluation of severity of glaucoma. METHODS: This was a prospective case-control study including 29 eyes with glaucoma. Besides, 28 eyes with senile cataract were used as control. Patients were classified into four groups: acute angle closure glaucoma (AACG), chronic angle closure glaucoma (CACG), primary open angle glaucoma (POAG) and senile cataract. Undiluted vitreous samples were collected, then vitreous concentrations of 9 types of cytokines were determined by cytometric bead assay system: γ-interferon (IFNg), interleukin (IL)-10, IL-2, IL-4, IL-5, interferon-γ-inducible protein (IP)-10, monocyte chemoattractant protein (MCP)-1, tumor necrosis factor (TNF)-α, and vascular endothelial growth factor (VEGF)...

The pulmonary neuroendocrine system includes pulmonary neuroendocrine cells (PNECs) and neuroepithelial bodies (NEBs) that are distributed throughout respiratory epithelium and regulate lung growth and maturation antenatally. Abnormalities in this system have been linked to many hypoxia-associated pediatric pulmonary disorders. Hemoglobin (Hb) Bart disease is a severe form of α-thalassemia resulting in marked intrauterine hypoxia with hydrops fetalis (HF) and usually death in utero. Affected fetuses can serve as a naturally occurring human model for the effects of intrauterine hypoxia, and we postulated that these effects should include changes in the pulmonary neuroendocrine system...

Many single-molecule (SM) label-free techniques such as scanning probe microscopies (SPM) and magnetic force spectroscopies (MFS) provide high resolution surface topography information, but lack chemical information. Typical surface enhanced Raman spectroscopy (SERS) systems provide chemical information on the analytes, but lack spatial resolution. In addition, a challenge in SERS sensors is to bring analytes into the so-called "hot spots" (locations where the enhancement of electromagnetic field amplitude is larger than 10(3))...

How should we begin to explore the complex considerations influencing young Indigenous New Zealand Māori women's sexuality? Centring a Māori woman's analysis through a Mana Wāhine methodology, and utilising an Indigenous form of storying, pūrākau, I explore this question by attending to my autobiographical memory of experiences of exotic dancing and moments of violence in heterosexual relationships. The analysis provides critical reflection on the interchanges between individual experience and the social and cultural conditions of a reality, informed by colonisation and historical trauma...

Membrane separation technologies are of great interest in industrial processes such as water purification, gas separation, and materials synthesis. However, commercial filtration membranes have broad pore size distributions, leading to poor size cutoff properties. In this work, mesoporous silica thin membranes with uniform and large vertical mesochannels are synthesized via a simple biphase stratification growth method, which possess an intact structure over centimeter size, ultrathin thickness (≤50 nm), high surface areas (up to 1420 m(2) g(-1) ), and tunable pore sizes from ≈2...

Regulatory T cells (Tregs) are an essential cell subset for the maintenance of immune homeostasis. Foxp3 (Forkhead box P3) is the Treg master gene which is essential for immune suppressing activity. In addition, Tregs are characterized by a distinct pattern of gene expression, including upregulation of immune-suppressive genes and silencing of inflammatory genes. The molecular mechanisms of Treg development and maintenance have been intensively investigated. Tregs are characterized by expression of the transcription factor Foxp3...

Heme binds Aβ to give a mixture of a mono-histidine bound high spin peroxidase type active site and a bis-histidine bound low spin cytochrome b type active site present in an equilibrium at physiological pH. Of these, the high spin mono-histidine bound complexes produce significant amounts of partially reduced oxygen species (PROS), catalyze the degradation of neurotransmitters and oxidize cytochrome c, with potentially detrimental effects. The presence of excess Aβ could lower these effects by creating a low spin bis-histidine cytochrome b type active site which exerts less oxidative stress by producing a much smaller amount of PROS...

Early infantile epileptic encephalopathy has a grave outcome. Dravet syndrome (DS), characterized by early onset, refractory seizures, and intellectual deficit is one of the variants of the condition. SCN1B gene mutation is one of the lesser known variants of DS. Increased awareness of genetic analysis has increased the early diagnosis of DS for an early prognostication as well as genetic counselling of parents. We present the case of a 7-month old male child who started having recurrent febrile, and thereafter, afebrile seizures, following administration of a vaccination at 3 months...

Diabetes increases the risk of physical dysfunction and disability. Diabetes-related complications and coexisting morbidities partially explain the deterioration in physical function. The decline in muscle mass, strength and function associated with diabetes leads to sarcopenia, frailty and eventually disability. Frailty acts as a mediator in the pathogenesis of disability in older people with diabetes and its measurement in routine daily practice is recommended. Frailty is a dynamic process which progresses from a robust condition to a pre-frail stage then frailty and eventually disability...

A superheated droplet detector (SDD) consists of a large number of micron-sized superheated liquid drops suspended in a gel medium. The vaporization of a superheated drop is associated with the emission of an acoustic signal. A novel optical method is developed for the detection of this acoustic signal. In this method, a probe-bubble picks up the acoustic signal, and the oscillation of the probe-bubble is detected by employing a laser and phototransistor. The method can detect vaporization of an individual superheated drop in real-time and can be used for studying the response of SDDs to ionizing radiations...
