Alkali burns are known to possess high pathological potential because of their inherent ability to lyse cell membranes and penetrate intraocular structures with devastating results. The authors aimed to evaluate the most common cause of this presentation, the current treatment approaches to injury, and eventual outcome as related to severity. The authors performed a retrospective review of all patients who sustained chemical-related ocular injuries seen at the Concord Hospital Burns Unit, Australia between January 2005 and March 2012.

The complete mitochondrial genome of Tor putitora, an endemic coldwater fish of Himalayas was determined for the first time. The genome is 16,576 bp in length and consists of 13 protein coding genes, 22 tRNAs, 2 rRNA genes and 1 putative control region. The gene organization and its order were similar to other vertebrates.

Cultured myoblasts have been used extensively as an in vitro model in understanding the underlying mechanisms of myogenesis. Various protocols for establishing a pure myoblast culture have been reported which involve the use of special procedures like flow cytometry and density gradient centrifugation. In goat, only a few protocols for establishing a myogenic cell culture are available and these protocols use adult muscle tissues which often does not yield sufficient numbers of precursor cells with adequate proliferative capacity.

Pulse oximeters have been widely used since the 1980s as they are considered to provide a safe, convenient, noninvasive method of estimating blood oxygen saturation. Initially used in the operating room by anesthesiologists, pulse oximetry has become ubiquitous in the healthcare setting. Although rare, serious burn injuries secondary to pulse oximetry have been reported.

Background: Post-lung-transplant bronchial stenosis (TBS) may cause significant morbidity and mortality. Although often transiently relieved by balloon bronchoplasty, stents may be required for long-term airway patency. We report a series of lung transplant patients in whom a silicone Y-stent was placed at the secondary carina for long-standing relief of post-transplant-airway stenosis.

The authors report an 18-mo-old girl who presented with features of incomplete Kawasaki disease and was refractory to intravenous immunoglobulin and infliximab treatment. She subsequently responded to pulse intravenous methylprednisolone therapy. The diagnostic dilemma arose after 2 mo when she developed clinical features suggestive of systemic onset juvenile idiopathic arthritis.

In this article a novel way of synchronizing two parallel connected sparkgap switches with accuracies of 1-5 ns for high frequency pulsed power applications is described. The circuit design of a synchronized sparkgap switch circuit is discussed. The circuit uses a combination of one master sparkgap and a set of inductor and capacitors to synchronize two sparkgaps and can be controlled via an IGBT switch.

Interferon stimulated gene 15 (ISG15), one of the several proteins induced by conceptus derived Type I and/or a Type II interferon (IFN), is implicated as an important factor in determining the uterine receptivity and conceptus development. However, presence as well as specific role of the ISG15 in buffalo (Bubalus bubalis) reproduction is yet to be elucidated. In the present study, both genomic and cDNA sequences of bubaline (bu) ISG15 were cloned and investigated for its expression in different tissues of female reproductive tract of buffalo.

This is the first study from north India that investigated the association of thrombomodulin (TM) polymorphisms with acute myocardial infarction (AMI) in 350 patients (≤ 40 years, n = 184 and ≥ 60 years, n = 166) and 350 matched-controls. The TM polymorphisms were determined by polymerase chain reaction-single-stranded conformational polymorphism and DNA sequencing. The TM 1418TT genotype (odds ratio [OR] 2.

Industrial waste is one of the main causes of environmental pollution. Laser-induced breakdown spectroscopy (LIBS) was applied to detect the toxic metals in the sludge of industrial waste water. Sludge on filter paper was obtained after filtering the collected waste water samples from different sections of a water treatment plant situated in an industrial area of Kanpur City.

Background: Rheumatic fever and chronic rheumatic heart disease (RHD) remains one of the most important causes of cardiovascular morbidity leading to a major public health problem, especially in developing countries. This was a pilot study to assess the presence of inflammation and expression of adhesion molecules by immunohistochemistry (IHC) in endomyocardial biopsy specimens of patients with chronic RHD.

Methods: Endomyocardial biopsy was obtained from 14 patients of chronic RHD with no features of activity clinically.

The present study evaluates the anti-inflammatory and antigranuloma activity of CLHE in experimental models, viz. carrageenan-induced paw edema, subcutaneous cotton pellet implantation-induced granuloma formation, and complete Freund's adjuvant-induced stimulation of peritoneal macrophages in rats. Serum TNF-alpha, IL-6, and IL-1 beta levels were estimated as markers for global effects of inflammation.

In this section, the authors present four interesting clinical cases that presented with common symptoms, but required careful clinical examination and investigations to arrive at a correct diagnosis and institute appropriate management. The first case is a 3-month-old infant who presented with hypertonia, bulging anterior fontanelle and tachycardia. ECG revealed supraventricular tachycardia which was managed appropriately.

Objective: The objective of this clinical review is to highlight the otolaryngological symptoms that occur in pregnancy. Where available, the authors discuss the current evidence of the etiology and management of the various presentations. While it is appreciated that many of these complaints are transient, their impact on the maternal quality of life can be significant, and therefore, medical practitioners should be aware of what to expect in order to provide reassurance to patients and also to safely manage such symptoms.

Background/aims: The benefits of adjuvant chemotherapy for colorectal cancer has been well accepted over the last decade. Published data so far has been focused in the direction of giving the right chemotherapy dose, schedule, and combinations, in order to increase the efficacy and decrease the toxicity.

Methodology: Eighty-seven patients with histological proved stage III rectal carcinoma were subjected to a combined adjuvant modality using laparoscopic heperthermic endoperitoneal chemotherapy (HIPEC) and systemic chemotherapy twenty days following the initial surgery.

Background And Aims: While the molecular basis of dilated cardiomyopathy (DCM) remains uncertain, concrete evidence is emerging that sarcomeric and cytoskeleton gene expression of myocardium isolated from failing versus non-failing patients differ dramatically. The central aim to this work was to find out the possible role of dystrophin and titin along with the TNF-alpha in the pathogenesis of cardiomyopathy.

Patients And Methods: mRNA levels and protein expression of a cytoskeletal protein, dystrophin and a sarcomeric protein, titin in endomyocardial biopsies of DCM patients were examined using RT-PCR and immunohistochemistry, respectively.

Celiac disease is predominantly a disease of the small intestine characterized by chronic malabsorption in genetically susceptible individuals who ingest grains containing gluten, such as wheat, barley and rye. Although previously believed to be uncommon, celiac disease may be present in up to 1% of the general population. Celiac disease is frequently associated with many extraintestinal disorders, but rarely with cardiomyopathy.
