Abstract
A total of 100 isolates of Pasteurella multocida from various ruminant species (cattle, buffalo and sheep) belonging to different parts of country were identified using Pasteurella multocida-PCR (PM-PCR) and capsular PCR assays. PM-PCR revealed an amplicon of approximately 460 bp in all the isolates tested. As regards capsular PCR, 36 of 38 cattle isolates and 30 of 34 buffalo isolates were found to belong to capsular serogroup B whereas rest of the cattle and buffalo isolates belonged to serogroup A of P. multocida. In case of sheep, a total of 26 out of 28 isolates were positive for serogroup A specific PCR while remaining 2 amplified a PCR product specific for serogroup F of P. multocida. All the isolates were subjected to antibiotic sensitivity testing using 17 different antibiotics. Enrofloxacin was found to be most potent antibiotic as it was effective against 94% of the isolates followed by ofloxacin (93%), chloramphenicol (93%), doxycycline (89%), tetracycline (86%) and ciprofloxacin (84%). Vancomycin, bacitracin and sulfadiazine were ineffective against P. multocida isolates showing 84%, 75% and 82% resistance, respectively. Further, the antibiogram also revealed the development of resistance against multiple drugs among various isolates of the organism.

Abstract
Formation of unstable plaques frequently results in atherothrombosis, the major cause for ischaemic stroke, myocardial infarction and peripheral arterial disease. Patients who have symptomatic thrombosis in one vascular bed are at increased risk of disease in other beds. However, the development of the disease in carotid, coronary and peripheral arteries may have different pathophysiology suggesting that more complex treatment protocols may have to be designed to reduce plaque development at different locations. In this review we describe the known risk factors, compare the developmental features of coronary and carotid plaque development and determine their association with end-point ischaemic events. Differences are also seen in the genetic contribution to plaque development as well as in the deregulation of gene and protein expression and cellular signal transduction activity of active cells in regions susceptible to thrombosis. Differences between carotid and coronary artery plaque development might help to explain the differences in anatomopathological appearance and risk of rupture.

Abstract
We report the observation of low-light level optical interactions in a tapered optical nanofiber (TNF) embedded in a hot rubidium vapor. The small optical mode area plays a significant role in the optical properties of the hot vapor Rb-TNF system, allowing nonlinear optical interactions with nW level powers even in the presence of transit-time dephasing rates much larger than the intrinsic linewidth. We demonstrate nonlinear absorption and V-type electromagnetically induced transparency with cw powers below 10 nW, comparable to the best results in any Rb-optical waveguide system. The good performance and flexibility of the Rb-TNF system makes it a very promising candidate for ultralow power resonant nonlinear optical applications.

Abstract
AIM Rheumatic mitral patients reach their fifth decade of life more often now than in the past. The purpose of this study is to provide insight into improving morbidity and mortality in these patients. METHODS This retrospective study included 105 patients aged 50 years or more. Seventy-five underwent mechanical valve replacement and 30 received a bioprosthetic valve. Data were collected from medical records and outpatient department (OPD) registers. Follow-up included transthoracic 2D echocardiography, supported by clinical parameters, and X-ray findings. RESULTS Mean age was 58.52+/-2.4 years. Follow-up period ranged from one to eleven years (mean 6.8+/-0.9 years). Immediate perioperative mortality included five patients (4.76%) and long term mortality included three patients (3%). 35 patients previously underwent closed and open commissurotomy and balloon valvotomy. Multivariate analysis showed age, repeat surgery, atrial fibrillation, tricuspid valve disease, and preoperative functional status to be incremental risk factors. Freedom from repeat operation at 3 and 6 years was 90% and 85% in group I (<60 years), respectively. Actuarial survival at 4 and 6 years of follow up was 94.24% and 88.52%, respectively. CONCLUSION With improving life expectancy and early interventions, the number of < or = 50-year old rheumatic valvular disease patients is increasing. The present study showed a marked improvement for this subset of patients, although age still remains the main risk factor along with atrial fibrillation, repeat surgery, stroke and tricuspid valve disease.

Abstract
Buffaloes in Indian subcontinent play an important role as the producer of milk and milk products. The alpha(s1)-casein constitutes 38% of the total milk proteins. The present study was carried out to characterize the gene in Murrah breed of Riverine buffalo. Buffalo alpha(s1)-casein cDNA was synthesized by RT-PCR, then cloned using pDRIVE-cloning vector and sequenced. The sequencing revealed that the size of alpha(s1)-casein cDNA was of 645 bp with GC content of 45.58%. The alpha(s1)-casein gene coded 214 amino acids precursor with a signal peptide of 15 amino acid residues. The similarity of buffalo alpha(s1)-casein mRNA sequence with that of cattle, goat, sheep, pig, camel, equine and human were estimated as 97.2, 93, 92.3, 57.2, 59.5, 55.9 and 46.6%, respectively. A similar trend was observed when compared amino acid sequences of these species. In the phylogenetic trees, constructed from the data of the alpha(s1)-casein mRNA as well as protein sequences, it has been observed that buffalo, cattle, goat and sheep formed a cluster with a closer relationship between cattle and buffalo followed by goat and sheep.

Abstract
A giant cell tumor with local aggressiveness and penetration of cartilage is quite rare. We present a case of fungating giant-cell tumor of lower end of the ulna with wrist involvement including penetration of cartilage and diaphysis. Involvement with all these characteristics, according to the literature reviewed, is the first case of its type. We are of the opinion that the fungation may be due to incision and drainage and delayed presentation at tertiary care centre.
