Issues and gaps in international guidance and national regulatory systems affecting international live insect trade.

International trade in live insects involves the shipping of many different species, for various purposes, with a variety of handling requirements regulated by numerous authorities with varying objectives. The diversity of factors at play has both created and been subject to a complex regulatory landscape. A review of global production, shipping and use experiences from a range of perspectives has shown gaps and inconsistencies in international guidance and national implementation. Private carriers add another layer of uncertainty that is disproportionate to risks, resulting in variable practices and charges. Many benefits can come from international trade in insects, including pollinator services, control of pests and of disease vectors, and enhanced international scientific research and innovation. These benefits will be better achieved through a more evidence-based and efficient approach to regulating trade. This change in approach will in turn require an improved and widely accepted risk-management landscape for insect trade.

Le commerce international d'insectes vivants s'appuie sur les expéditions de nombreuses espèces différentes à diverses fins, assorties de multiples exigences relatives à la manutention régies par des autorités différentes poursuivant des objectifs distincts. La diversité des facteurs en jeu a rendu nécessaire la création d'un paysage normatif complexe, avec les contraintes qui lui sont associées. L'examen à l'échelle mondiale de la production, du transport et des expériences dans ce domaine depuis diverses perspectives a révélé un certain nombre de lacunes et d'incohérences au niveau des directives internationales et de leurs applications concrètes dans les pays. Les transporteurs privés ajoutent une dimension d'incertitude supplémentaire qui est disproportionnée par rapport aux risques, ce qui entraîne une forte variabilité des pratiques et des charges. Les échanges internationaux d'insectes génèrent nombre d'activités bénéfiques, parmi lesquelles les services de pollinisation, la lutte contre les ravageurs et les vecteurs de maladie, et l'accroissement de la recherche scientifique internationale et de l'innovation. Les objectifs attendus seront mieux atteints en adoptant une approche de la réglementation des échanges qui s'appuie davantage sur des éléments factuels et sur les gains d'efficacité. Ce changement méthodologique nécessitera à son tour la mise en place d'un cadre amélioré et plus largement accepté de la gestion des risques dans le domaine du commerce des insectes.

El comercio internacional de insectos vivos, que supone el transporte de muchas especies diferentes con fines diversos, se acompaña de requisitos de manipulación que dictan numerosas autoridades con todo tipo de objetivos. La diversidad de los factores que entran en juego ha sido a la vez causa y consecuencia de un complejo panorama reglamentario. Los autores, tras describir un estudio a escala mundial de la experiencia de producción, transporte y utilización de insectos vivos desde diferentes puntos de vista, exponen las carencias e incoherencias observadas en las directrices internacionales y su traslación a escala nacional. Los transportistas privados añaden otro factor de incertidumbre que tiene un peso desproporcionado en relación con el nivel de riesgo y se traduce en procedimientos y precios heterogéneos. El comercio internacional de insectos puede traer consigo muchos beneficios, en particular servicios de polinización, control de plagas y de vectores de enfermedad, y avances de la investigación e innovación científica a escala internacional. Pero obtener esos beneficios será más fácil si se aborda la regulación del comercio de manera más eficaz y científicamente fundamentada, operando un cambio de lógica que exigirá, a su vez, la aplicación al comercio de insectos de un régimen más sofisticado y ampliamente aceptado de gestión de los riesgos.

International live insect trade: a survey of stakeholders.

There are significant numbers of transboundary shipments of live insects for pollination, pest management, industrial processes, research and other uses, but data collection and analysis have proved difficult. The World Organisation for Animal Health and Collectif TIS (Technique de l'Insecte Stérile), a French think tank, carried out a stakeholder survey to understand the nature of the live insect trade and potential challenges to safety and efficiency. Target respondents had experience in the areas of biocontrol, sterile insect technique, entomological research and regulatory affairs. Although the survey was sent globally, the responses were unintentionally biased towards Europe, where interest is high, since this region is developing a comprehensive framework to promote the use of beneficial insects to replace pesticides. The survey also explored respondents' knowledge of several international agreements on the movement and risk management of beneficial or invasive insects. Knowledge of the various regulations was generally poor, and respondents highlighted a perceived lack of clarity regarding live insect shipments in the existing international regulations and guidelines. Almost two-thirds of participants reported reluctance by carriers to accept live insects for shipment, and three-quarters described occasional to systematic delays that resulted in a reduction of quality or viability. Some respondents reported that they instead hand-carry live insects, mostly in small quantities. Participants described being directly involved in trade covering 70 species of live insects and ticks transported among 37 countries, with volumes ranging from fewer than ten insects to over a million per shipment. Of these, 30% were potential vectors of pathogens to humans or animals, 42% were potential plant pest species (including some used for biocontrol), and 17% were classical biocontrol agents. The results of this survey begin to define the current scope, scale and issues for those involved in shipping live insects and ticks across political boundaries. The survey's aim is to persuade regulatory bodies and shipping operators to facilitate safety, efficiency and consistency in this underdeveloped sector.

Les insectes vivants font l'objet d'un nombre important d'expéditions transfrontalières à des fins de pollinisation, de gestion des nuisibles, d'utilisation dans des processus industriels et de recherche, parmi d'autres emplois ; or, la collecte et l'analyse de données sur le sujet se sont révélées difficiles. L'Organisation mondiale de la santé animale et le Collectif TIS (Technique de l'insecte stérile), groupe de réflexion français, ont mené une enquête auprès de parties prenantes afin de comprendre la nature du commerce international d'insectes vivants ainsi que les éventuels problèmes de sécurité et d'efficacité qui lui sont associés. Les répondants sont des acteurs expérimentés dans les domaines du contrôle biologique, de la technique de l'insecte stérile, de la recherche entomologique et des questions réglementaires. Si le questionnaire a été distribué dans toutes les régions du monde, les réponses ont toutefois présenté un biais involontaire privilégiant l'Europe, région où l'intérêt pour cette question est élevé compte tenu du cadre réglementaire qui y est actuellement mis en place pour promouvoir l'utilisation des insectes utiles en replacement des pesticides. L'enquête visait également à déterminer le niveau de connaissance des répondants sur les divers accords internationaux relatifs aux mouvements d'insectes utiles ou envahissants, ainsi que sur la gestion des risques en la matière. Il en ressort que les diverses réglementations sont généralement méconnues, les répondants mettant en avant leur perception d'un manque de clarté des réglementations et directives internationales applicables aux expéditions d'insectes vivants. Près des deux tiers des participants ont fait état des réticences des transporteurs à accepter des cargaisons d'insectes vivants et les trois quarts d'entre eux ont rapporté des retards occasionnels ou systématiques se traduisant par une perte de qualité ou de viabilité. Certains répondants ont déclaré qu'ils préféraient transporter eux-mêmes les insectes vivants, la plupart du temps en petites quantités. Les répondants ont décrit leur participation directe dans des échanges couvrant au total 70 espèces de tiques et d'insectes vivants transportés dans 37 pays, avec des volumes allant de moins de dix insectes à plus d'un million d'insectes par cargaison. Parmi les espèces transportées, 30 % étaient potentiellement vectrices d'agents pathogènes pour les humains ou les animaux, 42 % étaient des nuisibles potentiels pour les végétaux (y compris certaines espèces utilisées à des fins de lutte biologique) et 17 % étaient des agents classiques de la lutte biologique. Les résultats de cette enquête permettent d'esquisser la portée et l'échelle des expéditions transfrontalières d'insectes vivants et de tiques, ainsi que la teneur des problèmes rencontrés par ceux qui y prennent part. L'objectif de l'enquête est de convaincre les organismes chargés de la réglementation ainsi que les transporteurs internationaux de la nécessité d'apporter de meilleures conditions de sécurité et d'efficacité à ce secteur sous-développé et d'en assurer la cohérence.

Pese al importante número de envíos transfronterizos de insectos vivos que se realizan con fines de polinización, gestión de plagas, procesos industriales, investigación u otros usos, hasta ahora ha resultado difícil reunir y analizar datos al respecto. La Organización Mundial de Sanidad Animal y el grupo de reflexión francés Collectif TIS (Technique de l'Insecte Stérile) hicieron una encuesta entre las partes interesadas con el fin de conocer mejor las características del comercio de insectos vivos y los factores que pueden amenazar su seguridad y eficacia. La encuesta iba dirigida a personas con experiencia en materia de control biológico, uso de la técnica del insecto estéril, investigaciones entomológicas o aspectos reglamentarios. Aunque la encuesta fue distribuida por todo el mundo, las respuestas presentaban un involuntario sesgo «europeo¼ debido al gran interés que el tema suscita en Europa, donde se está elaborando un marco reglamentario para promover el uso de insectos beneficiosos en sustitución de los plaguicidas. La encuesta indagaba asimismo en el grado de conocimiento que tenían los participantes de varios acuerdos internacionales relativos al desplazamiento de insectos beneficiosos o invasores y a la gestión de los riesgos conexos. En términos generales, los encuestados conocían poco las diversas reglamentaciones y destacaban lo que a su juicio era falta de claridad de las vigentes normativas y directrices internacionales por lo que respecta a los cargamentos de insectos vivos. Casi dos tercios de los participantes afirmaron que los transportistas eran reacios a aceptar cargamentos de insectos vivos y tres cuartas partes refirieron demoras ocasionales o sistemáticas que mermaban la calidad o viabilidad de las remesas. Algunos dijeron haber optado a cambio por el transporte manual de insectos vivos, casi siempre en pequeñas cantidades. Los encuestados afirmaron tomar parte directamente en un comercio que mueve 70 especies de insectos o ácaros vivos por 37 países, en cantidades que van desde menos de diez insectos a más de un millón de ejemplares por envío. De esas especies, un 30% correspondía a posibles vectores de patógenos humanos o animales, un 42% a posibles plagas vegetales (algunas de ellas utilizadas con fines de control biológico) y un 17% a agentes clásicos de control biológico. Los resultados permiten empezar a acotar el alcance, la escala y la naturaleza de los problemas a que se enfrentan quienes intervienen en el envío transfronterizo de insectos y ácaros vivos. La encuesta tiene por objetivo convencer a organismos de reglamentación y transportistas de que procuren fomentar la seguridad, eficiencia y coherencia de este infradesarrollado sector.

The in vitro toxicity of nitrile and epithionitrile derivatives of glucosinolates from swedes (Brassica napus) in human and bovine liver cells.

AIM: To investigate the direct in vitro toxicity in human and bovine liver cells, and inhibition of activity of ATP-binding cassette transporter G2 (ABCG2) and cytochrome P450 3A4 (CYP3A4) by five nitrile and epithionitrile derivatives from swede (Brassica napus). METHODS: The following compounds were investigated: 1-cyano-2-hydroxy-3-butene (CHB, epithionitrile derivative of progoitrin), 1-cyano-2-hydroxy-3,4-epithiobutane (epithionitrile derivative of progoitrin), 3-butenenitrile (nitrile from sinigrin), 4-pentenenitrile (nitrile from gluconapin), and 5-hexenenitrile (nitrile from glucobrassicanapin). Direct cytotoxicity was assessed by incubating the compounds (at 100 mM, 200 mM, 2 M) with human (HepG2) hepatocellular carcinoma cells or bovine primary hepatocytes for 24 hours. Cell viability was then assessed using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Cytotoxicity in Hep2G cells was also assessed after incubation for 72 hours at sub-chronic concentrations (1, 2.5, 5, 10, 15, 20 µM) and for combinations of compounds (20 µM). The ability of compounds to inhibit activity of the ABCG2 transporter and the CYP3A4 enzyme were assessed using human ABCG2 vesicles and demethylation of erythromycin by rat liver microsomes, respectively. RESULTS: No reduction of cell viability compared to control assays was observed when the tested compounds were incubated with Hep2G cells or bovine liver cells at concentrations up to 2 mM for 24 hours or with Hep2G cells at concentrations up to 20 µM for 72 hours. None of the five tested compounds inhibited the ability of the ABCG2 transporter to transport the fluorescent substrate at concentrations up to 2 mM. Furthermore, no inhibition of CYP3A4 activity (measured as N-demethylation of erythromycin) was observed for CHB up to 2 mM. CONCLUSION: This study suggests that under these conditions, the selected nitrile or epithionitrile derivatives of glucosinolates are not hepatotoxic in vitro.

Everolimus Eluting Stents in Patients with Diabetes Mellitus and Chronic Kidney Disease: Insights from the TUXEDO Trial.

BACKGROUND: Patients with diabetes and those with chronic kidney disease (CKD) are at increased risk of cardiovascular events. Everolimus eluting stents (EES) have been shown to be superior to paclitaxel eluting stents (PES) in patients with diabetes. However, it is not known if EES is as beneficial in diabetic patients with CKD compared with those without CKD. METHODS AND RESULTS: Patients enrolled in the TUXEDO-India trial, which is a clinical trial of patients with diabetes and coronary artery disease (CAD) randomly assigned to EES vs. thin-strut PES (Taxus Element), with data on baseline renal function were selected. CKD was defined as an estimated glomerular filtration rate (eGFR) <60 ml/min/1.73 m2 using the Cockcroft-Gault formula. Primary outcome was target vessel failure (TVF-defined as cardiac death, TV myocardial infarction (MI) or ischemia driven TV revascularization) at 1 year. Various secondary outcomes including stent thrombosis were evaluated. Among the 1821 patients with diabetes included in this analysis, 344 (19%) had CKD. In a propensity score adjusted analysis, patients with CKD had a significant increase in MACE (HR = 2.02; 95% CI 1.17-3.50; P = 0.01); death/MI/TVR (HR = 1.99; 95% CI 1.18-3.34; P = 0.009); death/MI (HR = 2.31; 95% CI 1.30-4.08; P = 0.004); cardiac death/MI (HR = 2.40; 95% CI 1.31-4.42; P = 0.005); death (HR = 2.88; 95% CI 1.35-6.13; P = 0.006) driven by an increase in cardiac death (HR = 3.33; 95% CI 1.42-7.83; P = 0.006) when compared with those without CKD. However, stent related events (TV-MI, TVR, TLR and stent thrombosis) were not different between CKD and non CKD groups. A significant interaction between CKD status and stent type (EES vs. PES) was noted for the outcomes of TVF (Pinteraction = 0.046), MACE (Pinteraction = 0.02), cardiac death or MI (Pinteraction = 0.05), non-target vessel related MI (Pinteraction = 0.04), non-Q-wave MI (Pinteraction = 0.03) and deaths/MI/TVR (Pinteraction = 0.04) such that EES was superior to PES in the non-CKD cohort but not in the CKD cohort. CONCLUSIONS: In subjects with diabetes, CKD is an independent predictor of adverse cardiovascular outcomes including increased risk of death driven largely by non-stent related events. While EES was superior to PES in patients without CKD, this was not the case in those with CKD (Clinical Trials Registry-India number, CTRI/2011/06/001830).

IMPPAT: A curated database of Indian Medicinal Plants, Phytochemistry And Therapeutics.

Phytochemicals of medicinal plants encompass a diverse chemical space for drug discovery. India is rich with a flora of indigenous medicinal plants that have been used for centuries in traditional Indian medicine to treat human maladies. A comprehensive online database on the phytochemistry of Indian medicinal plants will enable computational approaches towards natural product based drug discovery. In this direction, we present, IMPPAT, a manually curated database of 1742 Indian Medicinal Plants, 9596 Phytochemicals, And 1124 Therapeutic uses spanning 27074 plant-phytochemical associations and 11514 plant-therapeutic associations. Notably, the curation effort led to a non-redundant in silico library of 9596 phytochemicals with standard chemical identifiers and structure information. Using cheminformatic approaches, we have computed the physicochemical, ADMET (absorption, distribution, metabolism, excretion, toxicity) and drug-likeliness properties of the IMPPAT phytochemicals. We show that the stereochemical complexity and shape complexity of IMPPAT phytochemicals differ from libraries of commercial compounds or diversity-oriented synthesis compounds while being similar to other libraries of natural products. Within IMPPAT, we have filtered a subset of 960 potential druggable phytochemicals, of which majority have no significant similarity to existing FDA approved drugs, and thus, rendering them as good candidates for prospective drugs. IMPPAT database is openly accessible at: https://cb.imsc.res.in/imppat .

Genetic diversity studies and identification of SSR markers associated with Fusarium wilt (Fusarium udum) resistance in cultivated pigeonpea (Cajanus cajan).

Genetic diversity and identification of simple sequence repeat markers correlated with Fusarium wilt resistance was performed in a set of 36 elite cultivated pigeonpea genotypes differing in levels of resistance to Fusarium wilt. Twenty-four polymorphic sequence repeat markers were screened across these genotypes, and amplified a total of 59 alleles with an average high polymorphic information content value of 0.52. Cluster analysis, done by UPGMA and PCA, grouped the 36 pigeonpea genotypes into two main clusters according to their Fusarium wilt reaction. Based on the Kruskal-Wallis ANOVA and simple regression analysis, six simple sequence repeat markers were found to be significantly associated with Fusarium wilt resistance. The phenotypic variation explained by these markers ranged from 23.7 to 56.4%. The present study helps in finding out feasibility of prescreened SSR markers to be used in genetic diversity analysis and their potential association with disease resistance.

Common site of urinary calculi in kidney, ureter and bladder region.

Urolithiasis is an ancient disease with global distribution. It refers to stones originating anywhere in the urinary system. Urinary calculi or stones are the most common cause of acute urinary system obstruction. The study was aimed with finding out the common site of urinary calculus in kidney ureter bladder (KUB) region. This was a prospective cross-sectional study conducted from June 2012 to September 2012 at Tribhuvan University, Teaching Hospital, Maharajgunj. A total 240 urolitiasis patients were enrolled for plain KUB examination. Site of urinary calculus was identified by observing KUB film of the subjects under the supervision of radiologist. The data were analyzed prospectively with outcome measures of gender & stone location. Out of 240 patients, 138 were male and 102 were female with male to female ratio of 1.35:1. The age ranged from 9 to 83 years. Out of total 240 patients, 71.9% (187) patients belonged to productive age group (20-60 years). Total number of urinary calculi was 345 in which 208 were found in male patients and 137 were found in female patients. Of total 345 calculi, 237 were renal stones, 47 were ureteric stones, 22 of the stones were found in pelviureteric junction (PUJ), 33 of stones were found in vesicoureteric junction (VUJ), and 6 were in bladder. In conclusion, urinary stone disease is a major public health problem in a developing country like Nepal with male and productive age group predominance. Kidney stones are most common. Distal ureter is the most common site of ureteric stone.

Evaluation of the impact of HIV serostatus, tobacco smoking and CD4 counts on epidermoid anal cancer survival.

Tobacco smoking and HIV infection increase the risk of epidermoid anal cancer (EAC). No published studies have examined smoking and EAC outcomes, and the literature is discrepant regarding outcomes of HIV-positive patients with EAC. The goal of this study was to examine smoking history, HIV status and outcomes in EAC patients. We conducted a retrospective analysis of adults with invasive EAC treated in the University of Washington hospital system from 1 January 1994 to 31 December 2008. Sixty-three patients were included. Forty-seven patients (75%) had primary chemoradiation, of whom 42 (89%) completed therapy. Two patients (3%) received radiotherapy alone. Fourteen patients (22%) underwent primary surgery, of whom 11 (79%) underwent tumour excision and three (21%) abdominoperineal resection (APR). We analysed smoking history, HIV status and CD4 count (≥ 200 cells/µL/<200 cells/µL for HIV-positive patients) versus outcomes. Forty-five patients (71%) were in remission, and 44 (70%) were alive at last follow-up. Overall survival was significantly better for never-smokers than for ever-smokers. There were no differences in outcomes according to HIV status or CD4 counts. Patients with anal cancer who smoke have worse overall survival than non-smoking patients. HIV infection does not appear to affect anal cancer outcomes.

Combined high thoracic and lumbar epidural block for a patient with severe peripheral vascular disease undergoing axillo bifemoral bypass surgery.

A 63 years old patient with severely impaired pulmonary function presented with bilateral lower limb vascular blockade and was operated for emergency aortobifemoral bypass. The patient was considered to be at very high risk for general anesthesia but doing the case under regional anesthesia was also challenging because of the multiple dermatomal levels needed to be anesthetized and because of the potential of adverse effects with such extensive block. There are only a few reported cases of using combination of central neuraxial blocks. The procedure was successfully performed using combined high thoracic and lumbar epidural blockade with two different local anesthetics to minimizing toxicity and observing no adverse effects related to anesthesia technique.

An evaluation of patients care in Radio Diagnosis Department of Tribhuvan University Teaching Hospital, Kathmandu, Nepal.

Patients care involves all the activities that are carried out before, during and after radiological diagnostic procedures. The successful application of medical knowledge depends on what patients think and feel about the medical personnel and the hospital. From the clinical experience, patients usually reacts to some factors that creates problems in the radiology units such as delay, neglect, use of harsh words, unnecessary repeats and preferential treatment. The study was aimed at evaluating patients care in radio diagnosis department of Tribhuvan University Teaching Hospital (TUTH), Kathmandu, Nepal. A cross sectional study was conducted from May to June, 2012 in TUTH, Kathmandu, Nepal. Semi structured both open and closed ended questionnaires were administered among 287 conscious patients who were agreed to participate in the study. A total 287 patients were enrolled in the study. Out of them, 165 (57.49%) patients perceived that instruction was adequate before and after the examination; 219 (76.30%) patients were satisfied with the services rendered in the hospital; 174 (60.62%) patients perceived that privacy was adequate but 229 (79.9%) and 145 (50.5%) perceived that waiting areas and social aspects of patients care were suboptimal and in adequate. This can be improved by hospital management system.

Effect of probiotic fermented milk and chlorophyllin on gene expressions and genotoxicity during AFB1-induced hepatocellular carcinoma.

The aim of this study was to investigate the chemopreventive effect of probiotic fermented milk and chlorophyllin on aflatoxin B1 (AFB1) induced hepatocellular carcinoma. In vivo trials were conducted on 200 Wistar rats allocated to eight groups. Rats in the positive control group were given intraperitoneal injection of aflatoxin B1 at 450 µg/kg body weight twice a week for 6 weeks. The rats were sacrificed and dissected at 25th week of the experiment, and comet assay was carried out in hepatic cells to assess the genotoxicity or DNA damage. The tumour incidence was decreased by approximately one-third than AFB1 control group. The expression of c-myc bax, bcl-2, cyclin D1, p53 and rasp-21 genes was also studied. A significant (P<0.05) reduction in DNA damage was observed in probiotic fermented milk with chlorophyllin group as compared to aflatoxin B1 control group. The c-myc, bcl-2, cyclin D1 and rasp-21 level was found to be highest in AFB1 control group as compared to the treatment group. The results advocate the enhanced protective potential of probiotic fermented milk and chlorophyllin against AFB1-induced molecular alterations in hepatic cells during carcinogenesis.

A platelet tetraspanin superfamily member, CD151, is required for regulation of thrombus growth and stability in vivo.

BACKGROUND: This study was designed to determine the role of CD151 in platelet thrombus formation in vivo and define the contribution of platelet vs. endothelial CD151 in regulating platelet thrombus formation in vivo. METHODS AND RESULTS: Using intravital microscopy and ferric chloride (FeCl(3)) injury of mesenteric arterioles, we found that thrombi formed in CD151(+/-) and CD151(-/-) mice were smaller and less stable, than those formed in CD151(+/+) mice, with a tendency for embolization. Similarly, in Folt's FeCl(3)-induced carotid injury model, both CD151(+/-) and CD151(-/-) mice showed more prolonged times to 95% vessel occlusion than CD151(+/+) mice. In addition, laser-induced injury of cremaster muscle arterioles showed that thrombi formed in CD151(+/-) and CD151(-/-) mice were smaller and less stable than those formed in CD151(+/+) mice. Following platelet depletion/reconstitution with ex vivo-labeled donor platelets, platelet-depleted CD151(+/+) mice that received reconstitution with CD151(-/-) platelets had smaller thrombi that were unstable and embolized. In contrast, platelet-depleted CD151(-/-) mice that received reconstitution with CD151(+/+) platelets had normal thrombi that were stable. CONCLUSIONS: These data provide evidence that platelet CD151 is required for regulating thrombus formation in vivo.

Assessment of utilization of RCH services and client satisfaction at different level of health facilities in Varanasi District.

OBJECTIVE: To assess the various factors influencing utilization and non-utilization of RCH services and extent of client satisfaction. METHODS: A cross-sectional study was conducted during October to December 2008 at two selected blocks of Varanasi district, Uttar Pradesh. Principal study subjects were 509 women having children less than 12 months old, selected through a multistage sampling technique. Data were collected through in-depth interview and Focus Group Discussions conducted among the beneficiaries of the services. RESULTS: The study revealed that utilisation of the RCH services in the government facilities was higher among the backward classes than the general category; higher the level of education the lower was the utilisation of government services. Over all, 16% of the respondents were not satisfied with government facilities. 25% of the SC category was not satisfied with the services in spite of being the main users. Among RCH services utilization was highest (89%) for antenatal care services (ANC). 41.6% respondents did not receive any Post Natal Care (PNC) after their most recent birth. About 30% deliveries were at home out of which only 10% received PNC whereas out of 70% institutional deliveries about 80% received PNC. Overall 16.3 % of the respondents were not satisfied with the services provided by government health facilities. Around 16% and 14% were not satisfied with the behavior of medical officer and the health workers respectively and non-satisfaction was highest among SC category. CONCLUSION: All health facilities need to be made functional according to Indian Public Health Standards (IPHS) of NRHM.

Clonal variability and its relevance in generation of new pathotypes in the spot blotch pathogen, Bipolaris sorokiniana.

Spot blotch pathogen Bipolaris sorokiniana of wheat was investigated with threefold objectives: to establish a relationship between morphological and pathological variability of isolates, identify clonal genotype(s) acting as a source for the generation of new variability, and to determine the mechanism of generation of such variability in the pathogen. Isolates were collected from the leaves and seeds of field-grown wheat crop at four different sites in eastern Gangetic plains of India. Eighty-six clonal isolates derived from a single isolate (gray with white patches, Group III), which segregated in an equal proportion of parental and nonparental types, were studied. Morphological characters-i.e., colony morphology, growth rate, and sporulation-were studied along with disease-causing ability of the isolate clones. Clonal isolates were grouped into three categories. Microscopic analysis of nuclei was done to determine the causes of such variability. Morphological variability appeared to be related to the pathological variability. The isolate having epidemic potential appeared different than that acting as the reservoir for variability. The cause of such variability could be attributed either to hyphal fusion and heterokaryosis, nuclear migration and occurrence of multinucleate state, or a combination of these factors. Random Amplified Polymorphic DNA (RAPD) assay suggested that the unique fragments for different groups could be utilized as molecular markers to identify the isolates of specific groups.

Identification of molecular marker and aggressiveness for different groups of Bipolaris sorokiniana isolates causing spot blotch disease in wheat (Triticum aestivum L.).

One hundred fifty-five isolates of Bipolaris sorokiniana of wheat were studied for their morphopathological characterization. These isolates were grouped in five categories--black, brown/dull black, gray cottony growth, dull white/greenish black, and white--on the basis of their growth pattern. The frequency of the black suppressed type was maximum (45.63%), whereas the white isolate displayed lowest frequency (6.96%) in the natural population. Twenty RAPD (random amplified polymorphic DNA) primers were used to observe the variability among the identified groups of B. sorokininana. From each group, eight random isolates were investigated. A total of 143 bands were amplified, out of which 107 (74.83%) were polymorphic and 36 (25.17%) were monomorphic. On an average, the total numbers of bands generated per primer were 7.15, of which 5.35 and 1.80 were polymorphic and monomorphic, respectively. Dendrograms based on molecular polymorphism unveiled a considerable amount of diversity among the isolates. Specific DNA bands were identified for selected isolates. The distinct markers appeared to be potential enough to be employed as genetic fingerprints for future strain identification and classification. The study indicated that the RAPD primers provide an easy, rapid, and simple technique for the preliminary assessment of genetic diversity among the fungal isolates.

Biodegradable-polymer-based, paclitaxel-elutingInfinnium™ stent: 9-Month clinical and angiographic follow-up results from the SIMPLE II prospectivemulti-centre registry study

Background: SIMPLE II was a multi-centre, prospective registry study aimed at investigating the safety andefficacy of the Infinnium™ (Sahajanand Medical Technologies Pvt. Ltd, India) paclitaxel-eluting stent forthe treatment of single de novo lesions in the native coronary arteries.Methods: One hundred and three patients with symptomatic coronary artery disease were treated for singlede novo native coronary artery lesions using the Infinnium™ stent (paclitaxel concentration1.4 mcg/mm2 released over 48 days) in a multi-centre, prospective study performed on 3 continents (Asia,Europe and South America). The primary safety endpoint was major adverse cardiac events at 30 days(MACE 30d) and efficacy was assessed by in-stent binary restenosis as measured by quantitative coronaryangiography (QCA) at six-month follow-up. A clinical follow-up was scheduled at nine months.Results: The mean patient age was 58.5 years; 70.9% were males; 43.7% had unstable angina and 38.8%previous myocardial infarction. Risk factors included hypertension in 62.1%, hypercholesterolemia in52.4%, current smoking in 32.0% and diabetes in 28.2%. Stent implantation was successful in all patients,with more than one stent being implanted in 9 patients (8.7%). Hierarchical MACE 30d was 2.9%. At ninemonths, 101 patients had clinical follow-up (1 patient had died and 1 refused). There was one death(1.0%), one Q-wave myocardial infarction (Q MI) (1.0%), three non-Q MIs (2.9%), one clinically-driven targetlesion Coronary Artery Bypass Grafting (CABG) (1.0%), and one clinically-driven target lesion repeatpercutaneous coronary intervention (re-PCI) (1.0%). The overall event-free rate at nine months was 93.2%.QCA revealed in-stent and in-segment late loss of 0.38±0.49 mm and 0.18±0.46 mm, resulting in binaryrestenosis rates of 7.3% and 8.3%, respectively. There was one case of late stent thrombosis in the patientexperiencing the Q MI and subsequent re-PCI...

Dietary administration of bovine lactoferrin influences the immune ability of the giant freshwater prawn Macrobrachium rosenbergii (de Man) and its resistance against Aeromonas hydrophila infection and nitrite stress.

Haemocyte count, phenoloxidase activity, agglutinin levels, total protein content, bacterial clearance efficiency, resistance to the pathogen Aeromonas hydrophila and nitrite stress were measured in the giant freshwater inter-moult sub-adult prawn Macrobrachium rosenbergii (15-20 g) which had been fed diets containing bovine lactoferrin (Lf) at 50, 100, 200mg kg(-1) feed for 7 or 14 days. M. rosenbergii fed a diet containing 100mg Lf kg(-1) diet for 7 days showed significant (P<0.05) increase in total protein levels, agglutination titres against bacteria A. hydrophila and rabbit RBC, phenoloxidase activity, bacterial clearance (as observed through reduced number of circulating bacteria) as well as survival against A. hydrophila challenge. Increased bacterial clearance was also noticed in prawns fed Lf at 50 or 200mg kg(-1) for 14 days compared to control. Feeding of Lf at 50mg kg(-1) diet for 7 or 14 days was able to enhance only PO activity and reduce percent mortality against A. hydrophila challenge compared to its control. Total haemocyte count was higher in the lowest dose of Lf feeding, i.e. 50mg kg(-1) for 7 days. However, there was no significant alteration in the differential haemocyte population with respect to graded levels of Lf feeding for 7 or 14 days. A notable reduction in mortality percent after 120 h of nitrite stress was observed in prawn fed Lf at 100mg kg(-1) diet for 14 days. On the contrary, feeding of the highest dose of Lf, i.e. 200mg kg(-1) diet for 14 days failed to stimulate most of the innate immune parameters or reduce the percent mortality against A. hydrophila challenge or nitrite stress. It is therefore concluded that administration of Lf in the diet at 100mg kg(-1) for 7 days could enhance the immune ability of M. rosenbergii and increase its resistance to A. hydrophila infection or nitrite stress.

Biodegradable-polymer-based, paclitaxel-eluting Infinnium stent: 9-Month clinical and angiographic follow-up results from the SIMPLE II prospective multi-centre registry study.

BACKGROUND: SIMPLE II was a multi-centre, prospective registry study aimed at investigating the safety and efficacy of the Infinnium (Sahajanand Medical Technologies Pvt. Ltd, India) paclitaxel-eluting stent for the treatment of single de novo lesions in the native coronary arteries. METHODS: One hundred and three patients with symptomatic coronary artery disease were treated for single de novo native coronary artery lesions using the Infinnium stent (paclitaxel concentration 1.4 mcg/mm2 released over 48 days) in a multi-centre, prospective study performed on 3 continents (Asia, Europe and South America). The primary safety endpoint was major adverse cardiac events at 30 days (MACE 30d) and efficacy was assessed by in-stent binary restenosis as measured by quantitative coronary angiography (QCA) at six-month follow-up. A clinical follow-up was scheduled at nine months. RESULTS: The mean patient age was 58.5 years; 70.9% were males; 43.7% had unstable angina and 38.8% previous myocardial infarction. Risk factors included hypertension in 62.1%, hypercholesterolemia in 52.4%, current smoking in 32.0% and diabetes in 28.2%. Stent implantation was successful in all patients, with more than one stent being implanted in 9 patients (8.7%). Hierarchical MACE 30d was 2.9%. At nine months, 101 patients had clinical follow-up (1 patient had died and 1 refused). There was one death (1.0%), one Q-wave myocardial infarction (Q MI) (1.0%), three non-Q MIs (2.9%), one clinically-driven target lesion Coronary Artery Bypass Grafting (CABG) (1.0%), and one clinically-driven target lesion repeat percutaneous coronary intervention (re-PCI) (1.0%). The overall event-free rate at nine months was 93.2%. QCA revealed in-stent and in-segment late loss of 0.38+/-0.49 mm and 0.18+/-0.46 mm, resulting in binary restenosis rates of 7.3% and 8.3%, respectively. There was one case of late stent thrombosis in the patient experiencing the Q MI and subsequent re-PCI. CONCLUSIONS: The Infinnium paclitaxel-eluting stent appears to be safe and efficacious for the treatment of single de novo lesions in coronary arteries in a patient population with symptomatic coronary artery disease (CAD).

Trinucleotide repeat analysis of spinocerebellar ataxia patients in Oman.

OBJECTIVE: To explore the profile of cytosine/adenine/guanine (CAG) repeat expansion in Omani spinocerebellar ataxia (SCA) patients. METHODS: Ten SCA patients attending the Sultan Qaboos University Hospital Neurologic clinics, Al-Khoud, Oman in the 3 years starting from January 2000 were recruited for this study. Genomic DNA was extracted from peripheral blood samples and CAG repeat expansion analysis was carried out by polymerase chain reaction and sequencing, when required. RESULTS: The CAG triplet repeats leading to polyglutamine expansion and neurodegeneration are seen in spinocerebellar ataxias 1, 2, 3, 6, 7 and 17. By using primers for SCA 1, 2, 3 and 7, we found the repeats were in the normal range and triplet repeats do not seem to be a common cause for ataxia in Oman. CONCLUSION: Spinocerebellar ataxia in Oman has the normal range of CAG repeats for the commonly found SCA1, SCA2, SCA3 and SCA7.
