Abstract
PURPOSE Midostaurin, approved for treating FLT-3-mutated acute myeloid leukemia and advanced systemic mastocytosis, is metabolized by cytochrome P450 (CYP) 3A4 to two major metabolites, and may inhibit and/or induce CYP3A, CYP2B6, and CYP2C8. Two studies investigated the impact of midostaurin on CYP substrate drugs and oral contraceptives in healthy participants. METHODS Using sentinel dosing for participants' safety, the effects of midostaurin at steady state following 25-day (Study 1) or 24-day (Study 2) dosing with 50 mg twice daily were evaluated on CYP substrates, midazolam (CYP3A4), bupropion (CYP2B6), and pioglitazone (CYP2C8) in Study 1; and monophasic oral contraceptives (containing ethinylestradiol [EES] and levonorgestrel [LVG]) in Study 2. RESULTS In Study 1, midostaurin resulted in a 10% increase in midazolam peak plasma concentrations (Cmax), and 3-4% decrease in total exposures (AUC). Bupropion showed a 55% decrease in Cmax and 48-49% decrease in AUCs. Pioglitazone showed a 10% decrease in Cmax and 6% decrease in AUC. In Study 2, midostaurin resulted in a 26% increase in Cmax and 7-10% increase in AUC of EES; and a 19% increase in Cmax and 29-42% increase in AUC of LVG. Midostaurin 50 mg twice daily for 28 days ensured that steady-state concentrations of midostaurin and the active metabolites were achieved by the time of CYP substrate drugs or oral contraceptive dosing. No safety concerns were reported. CONCLUSION Midostaurin neither inhibits nor induces CYP3A4 and CYP2C8, and weakly induces CYP2B6. Midostaurin at steady state has no clinically relevant PK interaction on hormonal contraceptives. All treatments were well tolerated.

Abstract
PURPOSE To assess whether Ultrasound guided dry needling is adequate for both common extensor tendon tears and tendinosis or whether ultrasound guided platelet rich plasma (PRP) has a superior outcome when compared to dry needling when there are tears of the common extensor tendon. MATERIALS AND METHODS This is a single-centre, single-blinded, randomised controlled trial conducted between November 2018 and April 2020. 40 patients diagnosed with lateral epicondylitis based on clinical and sonographic features and having comparable baseline characteristics were randomly assigned to the two study groups (dry needling and PRP). Inclusion criteria were patients aged 20 years or more who were symptomatic for at least 3 months with sonographic evidence of lateral epicondylitis. Exclusion criteria were complete tear of common extensor tendon confirmed on ultrasound and presence of other associated diseases like osteoarthritis of shoulder and elbow. RESULTS There was significant improvement in the visual analogue scale pain score in PRP group compared to the dry needling group at 9 months. However, this difference was not evident at 3 and 6 months follow-up. Mean improvement in common extensor tendon thickness in PRP group (5.1 mm at 3 months and 4.3 mm at 6 months) was slightly better than dry needling (4.4 mm at 3 months and 4.0 mm at 6 months). There was no difference in tear (if present) healing between both groups at 3 months. However at 6 months follow up, PRP demonstrated significant (mean-2.5) healing in tear compared to dry needling (mean-3.1). CONCLUSION Two injections of Ultrasound guided PRP are more beneficial non operative treatment compared to ultrasound guided dry needling, in lateral epicondylitis.

Abstract
Freshwater habitats hold a unique role in the survival of all living organisms and supply water for drinking, irrigation, and life support activities. In recent decades, due to anthropogenic activities, deterioration in the water quality has been a long-lasting problem and challenge to the scientific fraternity. Although, these freshwater bodies have a bearable intrinsic capacity for pollution load however alarming increase in pollution limits the intrinsic capacities and requires additional technological interventions. The release of secondary pollutants from conventional interventions further needs revisiting the existing methodologies and asking for green interventions. Green interventions such as phycoremediation are natural, eco-friendly, economic, and energy-efficient alternatives and provide additional benefits such as nutrient recovery, biofuel production, and valuable secondary metabolites from polluted freshwater bodies. This systemic review in a nut-shell comprises the recent research insights on phycoremediation, technological implications, and influencing factors, and further discusses the associated mechanisms of metal ions biosorption by living and non-living algae, its advantages, and limitations. Besides, the article explores the possibility of future research prospects for applicability at a field scale that will help in the efficient utilization of resources, and improved ecological and health risks.

Abstract
Canine adenoviruses (CAVs) are of two types: canine adenovirus type 1 (CAV-1), which causes infectious canine hepatitis, and canine adenovirus type 2 (CAV-2), which is mainly associated with the respiratory type of disease in dogs. Due to the widespread use of modified live vaccines to control canine adenoviral infections and subsequently reduced disease incidence, CAVs are often neglected by clinicians. Although a number of studies are available about CAV-1 prevalence in India, only meagre information is available about CAV-2. This study reports the CAV-2 infection in a vaccinated dog with neurological and respiratory symptoms which was found negative for other canine pathogens like canine distemper virus and canine parvovirus. The virus was successfully isolated from rectal swab in MDCK cells and characterized by immunofluorescence assay and virus neutralization test. On phylogenetic analysis of partial E3 region, the Indian CAV-2 grouped in a separate clade different from established subgroups. An insertion of "G" nucleotide was reported at nucleotide (nt.) position 1077 in the E3 gene of Indian CAV-2 isolates which led to a frameshift in the coding region of E3 gene thereby imparting additional eleven amino acids to its C-terminal end in comparison to isolates from other parts of the world. This may have an implication on the functional role of E3 protein inside the cell. This study reinforces the unique signature insertion in the E3 gene of Indian CAV-2 and is the second study in the world to report the association of CAV-2 with neurological disease in dogs.

Abstract
The current pandemic caused by a novel coronavirus (SARS‐CoV‐2) has underlined the importance of emerging diseases of zoonotic importance. Along with human beings, several species of wild and pet animals have been demonstrated to be infected by SARS‐CoV‐2, both naturally and experimentally. In addition, with constant emergence of new variants, the species susceptibility might further change which warrants intensified screening efforts. India is a vast and second most populated country, with a habitat of a very diverse range of animal species. In this study we place on record of SARS‐CoV‐2 infections in three captive Asiatic lions. Detailed genomic characterization revealed involvement of Delta mutant (Pango lineage B.1.617.2) of SARS‐CoV‐2 at two different locations. Interestingly, no other feline species enclosed in the zoo/park were found infected. The epidemiological and molecular analysis will contribute to the understanding of the emerging mutants of SARS‐CoV‐2 in wild and domestic animals.

Abstract
Macrotyloma uniflorum is a salubrious but underutilized legume mainly consumed in semi-arid zones of Africa, Australia and India. Various antinutritional factors- phytates, oxalates and oligosaccharides- has limited its consumption. Current work describes the influence of various thermal processing technologies - autoclaving, microwave, micronization and extrusion- on antinutritional profile, phenolic acid profile and protein digestibility of two selected varieties. Significant (p ≤ 0.05) reduction in antinutritional content was observed for horse gram grains processed using various thermal technologies. Among all processing technologies extrusion caused marked degradation in antinutritional components. The reduction in oxalic acid, trypsin inhibitor, phytates and tannins ranged from 33 to 87 %, 77-82%, 33-60% and 51-66% respectively. Further, the decline in content of various oligosaccharides viz. raffinose, stachyose and verbascose varied from 36 to 61 %, 25-49% and 30-74% respectively for both the varieties. Although extrusion caused significant (p ≤ 0.05) decrease in the essential amino acid index and protein efficiency ratio, simultaneous increased was observed in biological value. The processing had significant (p ≤ 0.05) impact on grain antinutritional content and also retained its substantial functional properties. This establishes the utility of grain and promote the introduction of these new grains and enlarge the market of novel healthy foods.

Abstract
Study was conducted to determine the influence of different cooking methods namely pressure, flaking, infra-red, microwave and extrusion processing on rate of oxidative stability, fatty acid profile and functional properties of horse gram. The rate of auto-oxidation was significantly (p < 0.05) affected during storage and found maximum at 0.00 aw and minimum at 0.33 aw for both varieties namely GPM-6 and PAIYUR-2. The extrusion processed grains were more susceptible to auto-oxidation. The iron content of grain increased significantly (p < 0.05) during extrusion (1.22 ± 0.50 to 1.65 ± 0.15 mg 100 g-1 for PAIYUR-2 and 1.19 ± 0.45 to 1.59 ± 0.12 mg 100 g-1 for GPM-6). Whereas, tocopherol content decreased during extrusion (8.05 ± 0.15 to 2.28 ± 0.23 mg 100 g-1 for PAIYUR-2 and 6.48 ± 0.46 to 1.68 ± 0.15 mg 100 g-1 for GPM-6). Ellagic (12.36 ± 0.35 and 10.71 ± 0.29 mg 100 g-1), vanillic (15.20 ± 0.23 and 12.48 ± 0.18 mg 100 g-1), and coumaric acid (14.68 ± 0.71 and 8.97 ± 0.66 mg 100 g-1) were the major phenolic acids whereas, linoleic (35.53 ± 0.30 and 35.46 ± 0.19%), palmitic (26.08 ± 0.26 and 25.97 ± 0.33%), and linolenic acid (13.44 ± 0.18 and 10.13 ± 0.21%) were the major fatty acids present in raw grain for PAIYUR-2 and GPM-6 respectively. Phenolic and fatty acids were significantly (p < 0.05) affected during processing. The oxidative stability of microwave processed grains was maximum whereas, extrusion processed grains showed minimum oxidative stability during storage. Study explicitly describes that native grains and the grains which did not undergo destruction of naturally present cellular structure, were less prone to oxidation. The oxidation rate of grains was found dependent on composition, processing and storage environment of grains. Hence, all these factors need to be considered to ensure the stability of processed food during storage.

Abstract
The majority of tuberculosis cases in ruminants are caused by Mycobacterium bovis (MB). However, in this study, the authors reported the isolation of Mycobacterium tuberculosis (MT) from bovine milk, nasal swabs and post-mortem tissue samples (n = 841) collected from cattle and buffaloes in the states of Telangana, Maharashtra and Gujarat in India in the period from 2010 to 2015. The isolates (n = 7) were confirmed as Mycobacterium due to their growth characteristics and colony morphology in a commercial liquid medium Mycobacterial Growth Indicator Tube (MGIT)™ employing the BD BACTEC™ MGIT™ 960 system and the Löwenstein-Jensen (LJ) medium supplemented with glycerol but not with sodium pyruvate, and BD-DIFCO™ Middlebrook 7H10 agar containing oleic albumin dextrose catalase (OADC). These isolates were initially identified as members of the M. tuberculosis complex (MTC) using a commercial nested polymerase chain reaction (PCR) kit based on the IS6110 MTC specific nucleotide sequence. The isolates were confirmed as MT using three commercial line probe assay kits, were further genotyped, and the spoligotypes identified were of East African Indian (EAI) 3_IND, EAI5, Central-Asian (CAS) 1_DELHI, U and T1 lineages. Two MT isolates from one antelope (Antilope cervipara) andone gazelle (Gazella bennettii) from Gujarat, which were identified previously, were spoligotyped during this study and identified as belonging to EAI3_IND and EAI5 lineages, respectively. The epidemiological significance and zoonotic implications of regional presence and documentation of the same or two differents poligotypes in different species within the family Bovidae as well as humans is discussed.

Abstract
Effect of addition of multigrain premix (MGP) prepared using a combination of cereals, pulses and oilseeds at 40% level, on nutritional properties of multigrain biscuit, its in-vitro and in-vivo protein digestibility and protein profiling were studied. The incorporation of MGP significantly increased the protein content (from 7.37 to 16.61%), insoluble dietary fiber (from 1.71 to 6.67%), soluble dietary fiber (from 0.46 to 2.42%). The significant increase in the levels of isoleucine (ND-34.79%), methionine (0.04 to 7.65%), tryptophan (0.22 to 5.95%) valine (0.38 to 16.58%), lysine (0.36 to 7.32%), and threonine (0.51 to 7.2%) was observed, whereas fatty acid profile of MGP incorporated biscuits showed increased polyunsaturated fatty acids and decreased saturated fatty acids. The vitamin-mineral profile of MGP incorporated biscuits showed increased the thiamin (0.07-0.21 mg/100 g), riboflavin (0.09-0.28 mg/100 g), calcium (12.89-45.28 mg/100 g) and iron (1.13-3.47 mg/100 g) contents. The in-vitro protein digesibility of multigrain and control biscuits indicated that the proteins present in multigrain biscuits had high digestibility (71.73%) as compared to control biscuit (38.13%). The in-vivo studies indicated that, the protein quality of multigrain biscuits was comparable with casein protein with high protein efficiency ratio of 3.02. The electrophoretic pattern of multigrain biscuits showed subunit molecular weight distribution of different protein units and aggregation of protein bands at high molecular weight region of 85 to 166 kD. The outcome of the study indicated the possibility of utilising MGP to improve the overall nutritional quality of biscuits.

Abstract
Foot-and-mouth disease (FMD) is an important transboundary disease with substantial economic impacts. Although between-herd transmission of the disease has been well studied, studies focusing on within-herd transmission using farm-level outbreak data are rare. The aim of this study was to estimate parameters associated with within-herd transmission, host physiological factors and FMD virus (FMDV) persistence using data collected from an outbreak that occurred at a large, organized dairy farm in India. Of 1,836 regularly vaccinated, adult dairy cattle, 222 had clinical signs of FMD over a 39-day period. Assuming homogenous mixing, a frequency-dependent compartmental model of disease transmission was built. The transmission coefficient and basic reproductive number were estimated to be between 16.2-18.4 and 67-88, respectively. Non-pregnant animals were more likely to manifest clinical signs of FMD as compared to pregnant cattle. Based on oropharyngeal fluid (probang) sampling and FMDV-specific RT-PCR, four of 36 longitudinally sampled animals (14%) were persistently infected carriers 10.5 months post-outbreak. There was no statistical difference between subclinical and clinically infected animals in the duration of the carrier state. However, prevalence of NSP-ELISA antibodies differed significantly between subclinical and clinically infected animals 12 months after the outbreak with 83% seroprevalence amongst clinically infected cattle compared to 69% of subclinical animals. This study further elucidates within-herd FMD transmission dynamics during the acute-phase and characterizes duration of FMDV persistence and seroprevalence of FMD under natural conditions in an endemic setting.

Abstract
The goal of this study was to characterize the properties and duration of the foot-and-mouth disease (FMD) carrier state and associated serological responses subsequent to vaccination and naturally occurring infection at two farms in northern India. Despite previous vaccination of cattle in these herds, clinical signs of FMD occurred in October 2013 within a subset of animals at the farms containing juvenile-yearling heifers and steers (Farm A) and adult dairy cattle (Farm B). Subsequent to the outbreak, FMD virus (FMDV) asymptomatic carriers were identified in both herds by seroreactivity to FMDV non-structural proteins and detection of FMDV genomic RNA in oropharyngeal fluid. Carriers' seroreactivity and FMDV genome detection status were subsequently monitored monthly for 23 months. The mean extinction time of the carrier state was 13.1 ± 0.2 months, with extinction having occurred significantly faster amongst adult dairy cattle at Farm B compared to younger animals at Farm A. The rate of decrease in the proportion of carrier animals was calculated to be 0.07 per month. Seroprevalence against FMDV non-structural proteins decreased over the course of the study period, but was found to increase transiently following repeated vaccinations. These data provide novel insights into viral and host factors associated with the FMDV carrier state under natural conditions. The findings reported herein may be relevant to field veterinarians and governmental regulatory entities engaged in FMD response and control measures.

Abstract
The blends were prepared of virgin coconut oil with refined soyabean oil (VCO-RSOY) and refined safflower oil (VCO-RSAFF). Blending with VCO improved the fatty acid composition which increased the shelf stability of 20:80 VCO-RSOY and VCO-RSAFF up to 12 months in different packaging systems such as low density polyethylene, linear low density polyethylene, metalized polyester pouches, polyethylene teteraphthalate, high density polyethylene (HDPE), Amber HDPE bottle. The specific spectral regions of FTIR proved to be very useful for the determination of adulteration as well as for the study of oxidation process. Band shifts observed at 3008, 1652, 1397, 1097, 912 and 845 cm-1 have been used to differentiate RSAFF from VCO. VCO spectrums did not have these chemical shifts. Further the spectrum of RSOY showed same band shifts as RSAFF except 1652, 1397, 869.6 and 845 cm-1. Differential Scanning Calorimetry provided useful information regarding the nature of thermodynamic changes related to physical state of vegetable oil. The physical state changes included melting and crystallization events which require the intake and release of energy.

Abstract
Four different Multigrain Premixes (MGPs) namely MGP I, MGP II, MGP III, MGP IV were developed to select the best premix for preparation of biscuits based on nutritional value and biscuit quality. The MGPs were prepared using cereals (barley, sorghum, maize, oats), pulses (chickpea dhal, green gram, peas, soya flour), millets (pearl millet, finger millet) and wheat germ each at 20 % level. The MGPs developed had 22.91-27.84 % protein, 16.82-18.72 % dietary fiber and 3.11-3.46 % minerals. The wheat flour was replaced with MGPs separately at different levels of 10, 20, 30, 40 and 50 %. The incorporation of these MGPs significantly (p ≤ 0.05) decreased the water absorption (56.0-50.9 %), peak viscosity (273.67-154.92 RVU), biscuit spread ratio (10.28-8.15) and increased the pasting temperature (67.10-79.20 °C), dough hardness (311.66-460.26 N) and biscuit breaking strength (13.25-28.68 N). SEM studies showed that incorporation of MGP disrupted the protein matrix. Among the MGPs, MGP III was found to be more suitable even at the 40 % level for obtaining nutritious multigrain biscuits with higher protein, dietary fiber, and mineral content.

Abstract
Exploratory drilling was undertaken in the Lostoin block, West Khasi Hills district of Meghalaya based on the geological extension to the major uranium deposit in the basin. Gamma ray logging of drilled boreholes shows considerable subsurface mineralization in the block. However, environmental and exploration related challenges such as climatic, logistic, limited core drilling and poor core recovery etc. in the block severely restricted the study of uranium exploration related index parameters for the block with a high degree confidence. The present study examines these exploration related challenges and develops an integrated approach using representative sampling of reconnoitory boreholes in the block. Experimental findings validate a similar geochemically coherent nature of radio elements (K, Ra and Th) in the Lostoin block uranium hosting environment with respect to the known block of Mahadek basin and uranium enrichment is confirmed by the lower U to Th correlation index (0.268) of hosting environment. A mineralized zone investigation in the block shows parent (refers to the actual parent uranium concentration at a location and not a secondary concentration such as the daughter elements which produce the signal from a total gamma ray measurement) favoring uranium mineralization. The confidence parameters generated under the present study have implications for the assessment of the inferred category of uranium ore in the block and setting up a road map for the systematic exploration of large uranium potential occurring over extended areas in the basin amid prevailing environmental and exploratory impediments.

Abstract
Multiplex reverse-transcription polymerase chain reaction (mRT-PCR) assay is a sensitive and rapid method for the detection and serotyping of foot and mouth disease virus (FMDV). However, the method has not been used to its full potential, because of factors such as cost, a lack of infrastructure and the complexity of the reaction mixture. This study was undertaken to optimise and validate a thermostable, lyophilised, ready-to-use mRT-PCR kit for the rapid detection of FMDV in field laboratories in India. Trehalose, PEG-8000 and glycerol were evaluated for stabilisation of the PCR mixture at ambient temperatures. The lyophilised mRT-PCR kit was validated and found robust enough for use in field-level laboratories. The PCR reaction mixture in the ready-to-use kit has low complexity, so chances of cross-contamination during the preparation of the mixture are limited, but may easily be monitored by using lyophilised internal positive and negative controls. In addition, the requirement to maintain live FMDV isolates as internal positive controls at field-level regional laboratories is eliminated.

Abstract
Effect of spinach powder on the physico-chemical, rheological, nutritional and sensory characteristics on chapati premixes was studied by incorporating spinach powder at different concentrations from 1 % to 10 % based on wheat flour. Addition of 5 % of spinach powder to wheat flour was found to be optimum for chapati preparation. Effect of incorporation of spinach powder on the alveo-consistographic, mixographic and pasting characteristics were studied. It was observed that peak viscosity, breakdown viscosity significantly decreases whereas, peak time, tenacity increases with the increase in the concentration of spinach powder from 1 % to 10 % in chapati premixes. Addition of spinach powder also significantly affects the textural qualities of the chapaties. Premixes and prepared chapaties were also studied for chlorophyll content, total carotenoids,vitamins and minerals.

Abstract
Accurate and speedy estimations of ppm range uranium and thorium in the geological and rock samples are most useful towards ongoing uranium investigations and identification of favorable radioactive zones in the exploration field areas. In this study with the existing 5 in. × 4 in. NaI(Tl) detector setup, prevailing background and time constraints, an enhanced geometrical setup has been worked out to improve the minimum detection limits for primordial radioelements K(40), U(238) and Th(232). This geometrical setup has been integrated with the newly introduced, digital signal processing based MCA system for the routine spectrometric analysis of low concentration rock samples. Stability performance, during the long counting hours, for digital signal processing MCA system and its predecessor NIM bin based MCA system has been monitored, using the concept of statistical process control. Monitored results, over a time span of few months, have been quantified in terms of spectrometer's parameters such as Compton striping constants and Channel sensitivities, used for evaluating primordial radio element concentrations (K(40), U(238) and Th(232)) in geological samples. Results indicate stable dMCA performance, with a tendency of higher relative variance, about mean, particularly for Compton stripping constants.

Abstract
Urchin-like palladium nanostructures were synthesized by slow radiolytic reduction of Pd(II) in cetylpyridinium chloride (CPCl) micellar solution. They were formed by polycrystalline nanowires originating from the same core. The growth process leading to these urchin-like structures has been studied. These three-dimensional (3D) nanostructures were obtained at high Pd concentration (0.1 M) which led to a relatively large quantity of nanomaterials. These nanostructures show very interesting cycling sorption properties for hydrogen storage.

Abstract
INTRODUCTION Peyronie's disease is a common cause of sexual dysfunction. We assess the technique of plaque excision and dermal grafting for the treatment of Peyronie's disease. METHODS A total of 11 patients, aged 38-55 years, were operated for Peyronie's disease. All patients had stable plaque on the dorsum or dorsolateral aspect of the penile shaft. All patients had penile curvature, nine (81.8 percent) had painful erections, six (54.5 percent) had penile pain and three (27.3 percent) had erectile dysfunction. All suffered difficulty in intercourse. We performed plaque excision and dermal grafting. Main outcome measures were relief of penile pain, relief of painful erection, performance of satisfactory coitus and straight penis while erection. RESULTS All patients had relief of penile pain and painful erection. Nine (81.8 percent) patients had straight penis and had satisfactory coitus. Two (18.2 percent) patients suffered postoperative erectile dysfunction which was mild and responded to Sildenafil tabs. CONCLUSION Although experience with this technique is limited, the initial results are encouraging. We found this technique feasible with satisfactory results.

Abstract
BACKGROUND We sought to identify personal factors that placed people at risk during an epidemic of medically unexplained illness in a Bhutanese refugee camp in southeastern Nepal. METHODS We conducted a case-control study, involving 68 cases and 66 controls. Caseness was defined as experiencing at least one attack of medically unexplained fainting or dizziness during the time of the epidemic. We performed hierarchical logistic regression analysis to identify significant predictors of case status. RESULTS In terms of Western psychiatric constructs, the illness involved somatoform symptoms of both acute anxiety and dissociation. Sixty per cent reported visual and 28% reported auditory hallucinatory experiences. Cases and controls were similar on all demographic variables, school performance, number of attacks witnessed and psychopathology before the onset of the epidemic. Recent loss, early loss, childhood trauma and pulse-rate were predictors of case status. CONCLUSION We identified trauma, early loss and, especially, recent loss as predictors of attacks during medically unexplained epidemic illness in a Bhutanese refugee community.

Abstract
OBJECTIVE To assess the quality of health information on material safety data sheets (MSDS) for a workplace chemical that is well known to cause or exacerbate asthma (toluene diisocyanate, TDI). DESIGN We reviewed a random sample of 61 MSDSs for TDI products produced by 30 manufacturers. MEASUREMENTS AND MAIN RESULTS Two physicians independently abstracted data from each MSDS onto a standardized audit form. One manufacturer provided no language about any respiratory effects of TDI exposure. Asthma was listed as a potential health effect by only 15 of the 30 manufacturers (50%). Listing asthma in the MSDS was associated with higher toluene diisocyanate concentrations in the product (P <.042). Allergic or sensitizing respiratory reactions were listed by 21 manufacturers (70%). CONCLUSIONS Many MSDSs for toluene diisocyanate do not communicate clearly that exposure can cause or exacerbate asthma. This suggests that physicians should not rely on the MSDS for information about health effects of this chemical.

Abstract
The traditional view of injuries as "accidents", or random events, has resulted in the historical neglect of this area of public health. However, the most recent estimates show that injuries are among the leading causes of death and disability in the world. They affect all populations, regardless of age, sex, income, or geographic region. In 1998, about 5.8 million people (97.9 per 100,000 population) died of injuries worldwide, and injuries caused 16% of the global burden of disease. Road traffic injuries are the 10th leading cause of death and the 9th leading cause of the burden of disease; self-inflicted injuries, falls, and interpersonal violence follow closely. Injuries affect mostly young people, often causing long-term disability. Decreasing the burden of injuries is among the main challenges for public health in the next century--injuries are preventable, and many effective strategies are available. Public health officials must gain a better understanding of the magnitude and characteristics of the problem, contribute to the development and evaluation of injury prevention programs, and develop the best possible prehospital and hospital care and rehabilitation for injured persons.

Abstract
Patients with chronic obstructive pulmonary disease (COPD) are at a mechanical disadvantage and should be predisposed to the development of diaphragmatic fatigue when the ventilatory system is stressed by exercise. The purpose of this study was to determine whether patients with moderately severe COPD develop contractile fatigue of the diaphragm after cycle exercise to the limits of tolerance. Twelve male patients with COPD, age 61.4 +/- 3.0 yr, participated. Their forced expiratory volume in 1 s (FEV(1)) was 1.79 +/- 0.14 L, 49.6 +/- 3.4% of predicted. Patients cycled at 60-70% of their predetermined maximal work capacity until they had to stop because of intolerable symptoms. Twitch transdiaphragmatic pressure (Pdi,tw) was measured during cervical magnetic stimulation before and 10, 30, and 60 min after exercise. A persistent fall in Pdi,tw postexercise of >/= 10% was considered potentially indicative of contractile fatigue of the diaphragm. Patients cycled for 10.2 +/- 2.0 min at a workload of 59.9 +/- 4.3 W. Patients exercised maximally relative to their capacity reaching a peak oxygen consumption (V O(2)) of 108.1 +/- 2.8% of the peak V O(2) obtained during a preliminary maximal incremental exercise test. Pdi,tw was not significantly different from baseline at any time postexercise. Pdi,tw was 19.9 +/- 1.6 cm H(2)O at baseline, 19.6 +/- 2.0 cm H(2)O at 10 min postexercise, 18. 6 +/- 2.0 cm H(2)O at 30 min postexercise, and 19.5 +/- 1.7 cm H(2)O at 60 min postexercise. In the individual patients, two of the patients had a persistent >/= 10% fall in Pdi,tw postexercise, potentially indicative of contractile fatigue of the diaphragm. In conclusion, the majority of patients with moderately severe COPD do not develop contractile fatigue of the diaphragm after high-intensity constant workload cycle exercise to the limits of tolerance.

Abstract
The structural polypeptides of thirty-three field isolates of foot and mouth disease virus (FMDV) collected in India between 1977 and 1985 were analysed by SDS-polyacrylamide gel electrophoresis. They were placed in eleven groups based on their patterns and compared with results of conventional serological (virus neutralisation and complement fixation) tests. Variation occurred in the structural proteins of the viruses isolated between 1977 and 1981; however, the polypeptide patterns of viruses isolated in 1984 and 1985 were identical.

Abstract
In 1981 Entomological Field Research Units were established in three districts of Orissa State, India, from which Anopheles bloodmeals were forwarded regularly for analysis to an Entomological Laboratory in Bhubaneswar. At the onset of 1982, the laboratory introduced a modified gel diffusion technique for determining the origin of mosquito bloodmeals and by the end of 1983, 22,300 smears had been processed and analyzed. The technique is relatively very simple, fast and inexpensive. The results are reproducible and the use of double controls (negative and positive) ensure a high degree of reliability.

Abstract
The indirect immunofluorescence test was evaluated as a tool for malaria surveillance. The population of 12 villages in the East Champaran District of Bihar with a low annual parasitic index and a low annual blood examination rate was surveyed in order to confirm the low endemicity of malaria in these villages. Two specimens of blood, one taken during the pre-transmission season and one taken during the post-transmission season, were collected for parasitological and serological studies. The paired samples showed no parasite positivity in the study population in both surveys. All the villages had very low serological titres. However, the presence of malaria antibodies in the zero to five years age group (the sentinel group) indicated that malaria transmission occurred in the study area at a very low level. The seropositivity and the geometric mean titre were lower in the pre-transmission season than in the post-transmission season, but the overall reduction in geometric mean titre, which was very low throughout the study, was not statistically significant. The study emphasizes the importance of serological tests in malaria surveillance.

Abstract
Pulmonary megakaryocytes were quantitated in a series of 30 consecutive hospital necropsies using a two stage immunoperoxidase stain for factor VIII related antigen. In all 30 cases they were found with a mean density of 14.65 megakaryocytes/cm2 in lung sections of 5 micron in thickness. The maximum concentration of intrapulmonary megakaryocytes was consistently found to be in the central zone of the right upper lobe. Less than 22% of the observed cells possessed abundant cytoplasm, the rest appearing as effete, naked, and seminaked nuclei. The mean megakaryocyte count was found to be increased in association with both respiratory pathology (positive smoking history and impaired lung function) and cardiovascular disease states--shock; thromboembolism; myocardial infarction; and severe atheroma in the abdominal aorta, the coronary circulation, and the circle of Willis. Pulmonary megakaryocytes probably embolise from bone marrow. This may reflect stimulated thrombopoiesis, caused by increased platelet consumption in association with atherosclerotic disease, but it cannot be taken to confirm that the lung is the principal site of platelet production.
