The use of high voltage (HV) electrodes in vacuum is commonplace in physics laboratories. In such systems, it has long been known that electron emission from an HV cathode can lead to bremsstrahlung x rays; indeed, this is the basic principle behind the operation of standard x-ray sources. However, in laboratory setups where x-ray production is not the goal and no electron source is deliberately introduced, field-emitted electrons accelerated by HV can produce x rays as an unintended hazardous byproduct. Both the level of hazard and the safe operating regimes for HV vacuum electrode systems are not widely appreciated, at least in university laboratories...

BACKGROUND: Masson's hemangioma is a rare pathological entity, featuring intravascular papillary endothelial hyperplasia. Although benign, this hemangioma grows to form an expansile compressing mass. This lesion is mostly seen in skin and subcutaneous tissue. Occurrence in neuraxis is rare for this pathological entity. Still rarer is the spinal location with only 5 case reports published till date in medical literature. CASE DESCRIPTION: Here we present a 26 year old male with paraplegia due to extradural compression at D4, D5 level...

Management of women with Complete Heart Block (CHB) presenting without pacing, during pregnancy and labour is debatable. Temporary pacemakers have been routinely inserted for labour and birth probably to withstand any haemodynamic variations. However, due to lack of large scale prospective studies, the necessity of this procedure has not been objectively assessed. Also, the most appropriate anaesthetic technique for caesarean section in women with CHB is yet to be clarified. We report herein the case of a pregnant woman with CHB who had uneventful emergency caesarean delivery under spinal anaesthesia without temporary pacing...

We earlier reported thiophene-containing trisubstituted methanes (TRSMs) as novel cores carrying anti-tubercular activity, and identified S006-830 as the phenotypic lead with potent bactericidal activity against single- and multi-drug resistant clinical isolates of Mycobacterium tuberculosis (M. tb). In this work, we carried out additional synthesis of several TRSMs. The reaction scheme essentially followed the Grignard reaction and Friedel-Crafts alkylation, followed by insertion of a dialkylaminoethyl chain...

Mycobacterium tuberculosis is a human pathogen that secretes a major immunodominant antigen namely Hsp16.3 throughout the course of infection. It belongs to small heat shock protein family and exhibits molecular chaperone function which is important for the growth and survival of M. tuberculosis in host cell macrophages. The importance of the N-terminal region on the structure and chaperone function of Hsp16.3 is well understood. However, the effect of the C-terminal region on these properties is far from clear...

REVIEW
Satchidananda Panda
A majority of mammalian genes exhibit daily fluctuations in expression levels, making circadian expression rhythms the largest known regulatory network in normal physiology. Cell-autonomous circadian clocks interact with daily light-dark and feeding-fasting cycles to generate approximately 24-hour oscillations in the function of thousands of genes. Circadian expression of secreted molecules and signaling components transmits timing information between cells and tissues. Such intra- and intercellular daily rhythms optimize physiology both by managing energy use and by temporally segregating incompatible processes...

The common blood feeder mites of poultry are from the genera Dermanyssus and Ornithonyssus. Their presence are problematic for the producers either through potential direct effects on weight gain, egg production or sperm production in roosters or as nuisance pests on workers. They also cause anaemia in birds and play a vector role for several human and animal diseases. Five poultry farm buildings of Vikarabad area of Rangareddy district were visited. Samples were collected from a variety of sites, including beneath feed troughs, inside cage fittings and fastening clips, under egg conveyer belts and under manure belts...
