Abstract
BACKGROUND Stress fracture is the single most common cause for the lost number of manpower days during training. The conventional treatment options begin with rest and cessation of precipitating activity. However the demands of military training provide little tolerance for prolonged periods of rest. In the recent past ultrasound therapy (UST) has been reported to speed up healing of stress fractures. METHODS In the present study, a total of 67 cases of stress fracture were studied for the effect of ultrasound therapy on healing time. Study protocol used was double blind placebo controlled. RESULT Study results showed that the mean number of days of incapacitation was 25.46 days in the ultrasound treatment group as compared to 39.92 in the placebo group, a difference of 14 days, which was statistically highly significant. CONCLUSION The results of the study convincingly prove that ultrasound treatment is effective in cases of stress fracture.

Abstract
BACKGROUND AND PURPOSE Chemokines play a critical role in the pathogenesis of asthma and facilitate the recruitment of inflammatory cells in the airways. Evidence now suggests that airway smooth muscle (ASM) may serve as a source of chemokines in inflamed airways. Although vitamin D has potent anti-inflammatory properties in vitro in some cell types, its effects on ASM cells remain unclear. Here, we investigated whether 1alpha, 25-dihydroxy vitamin D3 (calcitriol) modulated chemokine production in ASM. EXPERIMENTAL APPROACH Human ASM cell cultures were derived from tracheal samples taken during surgery. ASM cells were treated with tumour necrosis factor alpha (TNFalpha) and/or interferon gamma (IFNgamma) for 24 h in the presence of calcitriol and/or the glucocorticoid fluticasone added 2 h before. RANTES (regulated upon activation, normal T-cell expressed and secreted), interferon-inducible protein 10 (IP-10) and fractalkine (FKN) levels in cell supernatants were measured by ELISA. KEY RESULTS In TNFalpha-treated cells, calcitriol inhibited RANTES and IP-10 secretion in a concentration-dependent manner. FKN levels were negligible. In TNFalpha/IFNgamma-treated cells, whereas fluticasone or calcitriol alone partially inhibited RANTES secretion (by 38 and 20%, respectively), the combination of both drugs additively inhibited RANTES secretion (by 60%). No effect was observed on IP-10 secretion. Whereas fluticasone enhanced FKN secretion (by 50%), calcitriol significantly decreased FKN levels (by 50%). Interestingly, calcitriol blocked the stimulatory effect of fluticasone on FKN secretion, which was inhibited by 60% with the combination of calcitriol and fluticasone. CONCLUSIONS AND IMPLICATIONS These findings suggest that vitamin D uniquely modulates human ASM expression of chemokines and may exert some beneficial effects in the treatment of steroid-resistant patients with asthma.

Abstract
Over six million people in nine districts of West Bengal, India are exposed to very high levels of arsenic primarily through their drinking water. More than 300,000 people showed arsenic-induced skin lesions in these districts. This is regarded as the greatest arsenic calamity in the world. Chronic arsenicosis causes varied dermatological signs ranging from pigmentation changes, hyperkeratosis to non-melanocytic cancer of skin, and also malignancies in different internal organs. Higher incidences of opportunistic infections are found in the arsenic-exposed individuals, indicating that their immune systems may be impaired somehow. We have thus investigated the effect of arsenic on T-cell proliferation and cytokine secretion in 20 individuals with arsenic-induced skin lesions and compared the results with 18 arsenic-unexposed individuals. A marked dose-dependent suppression of Concanavalin A (Con A) induced T-cell proliferation was observed in the arsenic-exposed individuals compared with the unexposed ( P < 0.001) individuals. This correlated with a significant decrease in the levels of secreted cytokines by the T cells (TNF-α, IFN-γ, IL2, IL10, IL5, and IL4) in the exposed individuals ( P < 0.001). Thus it can be inferred that arsenic exposure can cause immunosuppression in humans.

Abstract
Calcium movement is important in the activation of inflammatory cells. Prior studies have shown that calcium channel blockers (CCBs) inhibit carrageenan-induced paw edema in rats by acting at pituitary and hypothalamic levels. Here we evaluated the role of calcium channel blockers and their regulation via the hypothalamus-pituitary-adrenal (HPA) axis in acute and chronic models of rat paw inflammation, using both carrageenan (acute) and formalin (chronic) as inflammation inducers. Adrenalectomized (ADX) and intact Sprague Dawley rats (n = 4 per group) weighing 150-250 each were treated with an intraperitoneal injection of nifedipine (400 microg/kg) or vehicle. Edema was assessed plethysmometrically by evaluating paw volume changes. The results show a significant contradiction between acute and chronic inflammation data. In intact animals, nifedipine demonstrated a significant anti-inflammatory effect in the acute inflammatory model but not in the chronic model. In adrenal-ectomized animals, the anti-inflammatory effect of nifedipine was significantly enhanced both in acute and chronic models. We conclude that adrenalectomy plays a significant role in modulating the inflammatory pathway in the presence of calcium channel blockers.

Abstract
Vector transmitted diseases are often a serious threat for child health, especially for children traveller in tropical regions. Few arthropod borne diseases are preventable by immunization or chimioprophylaxis. Prevention of most of them is based on personal protection against arthropod bites. The evidence of its efficacy has been established by the use of impregnated bed nets, impregnated clothes with permethrin or mosquito repellent which reduced significantly child malaria morbidity and mortality in endemic countries. These personal protective measures are able to minimize arthropod bites and prevent Chikungunya infection, dengue fever and Lyme disease. The choice of a repellent among the commercialised products need to be efficacy and safety evidence based. This article propose to raise this issue and to give pragmatic recommendations, with a focus to children below 30 months who are at a high toxicological risk. Severity of these diseases allowed to use potentially toxic repellents if misused.

Abstract
Multivariable process control forms an important part of modern day control. While hardwired controllers still constitute the basic component of such control systems, with reducing communication latencies, controllers on the network are being mooted as a viable alternative. These controllers promise a large number of advantages in terms of reduction in wiring and greater flexibility in implementing supervisory control systems. In this paper, a study is presented which shows that UDP (User Datagram Protocol) can actually be used for real-time multivariable process control. Latency reduction algorithms used in high performance message passing systems have been used.

Abstract
BACKGROUND Armed forces personnel deployed in the North Eastern states of India are vulnerable to falciparum malaria. This vulnerability increases during mobilization of troops. METHODS Epidemiological case sheet was used for recording individual movement, clinical features and laboratory investigations of each case of malaria. Immunochromotography test (ICT) or Paracheck Pf was used as a rapid test for falciparum malaria at the regimental aid post (RAP). Subsequently, a case control approach was used to ascertain whether the cases of malaria differed significantly from healthy controls in observing antimalaria measures such as the use of mosquito nets, repellants and chemoprophylaxis. RESULT Nineteen out of 623 soldiers suffered from falciparum malaria during a short period of ten days during operational mobilization. Use of mosquito nets and repellants was significantly less among the cases as compared to healthy controls. There was no significant difference among the two groups regarding compliance with chemoprophylaxis. CONCLUSION A paradigm of "malaria on the move" or "operational malaria" has been proposed.

Abstract
BACKGROUND Assessing the extent of ulcerative colitis determines therapeutic strategies and provides prognostic information. Colonoscopy with mucosal biopsy is considered unsafe in patients with severe disease. AIM To assess the correlation between proximal extent of ulcerative colitis as determined by Technitium-99-m hexamethylpropylene amine oxime labelled leucocyte scan (white cell scan) with that determined by histological assessment. METHODS One hundred and thirty-five patients, with histologically-confirmed ulcerative colitis, who had a white cell scan and histological assessment of colonic inflammation within 6 months of each other, during the years 1991-2004, were included. Overall agreement, quadratic-weighted kappa (kappa) and polychoric correlations (rho) were calculated to estimate the inter-rater reliability. RESULTS The correlation between white cell scan and histological extent was excellent (kappa = 0.7 rho = 0.8). Macroscopic appearance on colonoscopy did not correlate as well with histological extent (kappa = 0.62 and rho = 0.67). White cell scans correlated significantly better in patients with extensive disease (P = 0.02). Colonoscopy predicted disease extent more accurately in patients with limited colitis (P = 0.002). CONCLUSIONS Proximal extent of ulcerative colitis determined by white cell scans correlates well with histological assessment especially in patients with more extensive disease. White cell scans offer a reasonable alternative to colonoscopy with mucosal biopsies in determining the proximal extent of colitis.

Abstract
We report the demonstration of time-correlated single-photon counting (TCSPC) fluorescence lifetime imaging (FLIM) to ex vivo decayed and healthy dentinal tooth structures, using a white-light supercontinuum excitation source. By using a 100 fs-pulsed Ti:Sapphire laser with a low-frequency chirp to pump a 30-cm long section of photonic crystal fibre, a ps-pulsed white-light supercontinuum was created. Optical bandpass interference filters were then applied to this broad-bandwidth source to select the 488-nm excitation wavelength required to perform TCSPC FLIM of dental structures. Decayed dentine showed significantly shorter lifetimes, discriminating it from healthy tissue and hard, stained and thus affected but non-infected material. The white-light generation source provides a flexible method of producing variable-bandwidth visible and ps-pulsed light for TCSPC FLIM. The results from the dental tissue indicate a potential method of discriminating diseased tissue from sound, but stained tissue, which could be of crucial importance in limiting tissue resection during preparation for clinical restorations.
