Abstract
We present new experimental constraints on the WIMP-nucleon spin-dependent elastic cross sections using data from the first science run of ZEPLIN-III, a two-phase xenon experiment searching for galactic dark matter weakly interacting massive particles based at the Boulby mine. Analysis of approximately 450 kg x days fiducial exposure allow us to place a 90%-confidence upper limit on the pure WIMP-neutron cross section of sigma(n)=1.9x10(-2) pb at 55 GeV/c(2) WIMP mass. Recent calculations of the nuclear spin structure based on the Bonn charge-dependent nucleon-nucleon potential were used for the odd-neutron isotopes 129Xe and 131Xe. These indicate that the sensitivity of xenon targets to the spin-dependent WIMP-proton interaction could be much lower than implied by previous calculations, whereas the WIMP-neutron sensitivity is impaired only by a factor of approximately 2.

Abstract
Abstract
A nonheme chloroperoxidase gene (cpo-p) from Pseudomonas pyrrocinia, a growth inhibitor of mycotoxin-producing fungi, was introduced into peanut via particle bombardment. The expression of the cpo-p gene is predicted to increase pathogen defense in peanut. Embryogenic peanut tissues were bombarded with gold particles coated with plasmid pRT66 carrying the cpo-p and hygromycin phosphotransferase (hph) genes, under the control of a double CaMV 35S and a single CaMV 35S promoter, respectively. Selection for hygromycin-resistant somatic embryos was performed on a liquid medium containing 10–20 mg/L hygromycin 3–4 days after bombardment. The integration and expression of the cpo-p gene was confirmed by Southern, Northern and Western blot analyses. In vitro bioassay using crude protein extracts from transgenic T0, T1, and T4 plants showed inhibition of Aspergillus flavus hyphal growth, which could translate to a reduction in aflatoxin contamination of peanut seed.

Abstract
Nanostructured Lipid Carrier (NLC)-based topical gel of Valdecoxib was formulated with the aim of faster onset yet prolonged action for the treatment of inflammation and allied conditions. NLCs prepared by microemulsion template technique were characterized by photon correlation spectroscopy for size. Drug encapsulation efficiency was determined using Nanosep centrifugal device. The nanoparticulate dispersion was suitably gelled and characterized with respect to drug content, pH, spreadibility, rheology, and in-vitro release. Safety of the NLC-based gel was assessed using primary skin irritation studies, and efficacy was confirmed using pharmacodynamic study, namely the Aerosil-induced Rat Paw edema model. The developed NLC-based gel showed faster onset and elicited prolonged activity up to 24 hours.

Abstract
BACKGROUND Ascariasis is the infestation by the largest intestinal nematode of man, a common problem in the tropics attributed to poor hygienic and low socioeconomic conditions. The aim of this research is to analyse the presentation, diagnosis and management of bowel obstruction caused by Ascaris lumbricoides, with special emphasis on the role of conservative management. MATERIALS AND METHODS This is a single centre, two consultant based 5 year retrospective study of childhood intestinal obstruction due to worms. Diagnosis in the suspected patients was based on history of passage of worms per mouth or rectum and on x-ray and ultrasonography findings. Only the patients of intestinal obstruction with documented evidence of roundworm infestation were included in the study and were followed for one year. RESULTS One hundred and three children with intestinal obstruction due to Ascaris lumbricoides were treated in the past five years at our centre. Abdominal pain was the most common presentation seen in 96 children followed by vomiting in 77 children. 20 children had history of vomiting worms and another 43 had history of passing worms in stool. Abdominal tenderness was present in 50 children, 48 had abdominal distension of varying degree, 50 had abdominal mass due to worm bolus, and 16 had or developed abdominal guarding or rigidity. All the children were managed as for acute intestinal obstruction along with hypertonic saline enema. The aim of management was "to starve the worm and hydrate the patient". 87 patients (84.47%) responded favourably and were relieved of the obstruction by the conservative management, 16 children (15.53%) had abdominal guarding or rigidity and underwent emergency exploration. CONCLUSION Roundworm obstruction should be considered in the differential diagnoses of all cases of intestinal obstruction in children. Clinical history and examination along with X-ray and ultrasonography are very helpful for diagnosis of this surgical emergency. Most cases of intestinal obstruction due to Ascaris can be managed conservatively; however emergency surgery is needed in patients with abdominal guarding and rigidity.

Abstract
Over the counter (OTC) drugs are commonly used by pregnant women. Most OTC drugs are safe in pregnancy but some have unproven safety and may adversely affect the growing foetus. The safety profile of some of the medication may change according to the gestational age of the foetus. Because an estimated 10% or more of the birth defects results from maternal drug exposure, the US Food and Drug Administration (FDA) has assigned a risk category to each drugs. Among the commonly used OTC drugs Acetaminophen, Chlorpheniramine, Kaolin and Pectin preparations and most antacids have a good safety record. The drugs like H2 blockers; Pseudoephedrine and Atropine/Diphenoxylate should be used with caution. The risk and benefit while using OTC drugs in pregnancy has to be assessed.

Abstract
BACKGROUND AND STUDY AIMS Rising demand for general diagnostic upper gastrointestinal endoscopy in the UK is outgrowing the capacity of doctors to provide this service within a reasonable time. One solution is to train nurses to carry out the procedure, but it is not known whether nurses can perform general diagnostic upper gastrointestinal endoscopy as competently as doctors. PATIENTS AND METHODS A randomized controlled non-inferiority trial compared the adequacy and the accuracy of diagnostic upper gastrointestinal endoscopies performed by five medical and two nurse endoscopists. The videotaped procedures were assessed by a consultant gastroenterologist blinded to the identity of the endoscopist. RESULTS 641 patients were randomly allocated (before attendance and consent procedure) to endoscopy carried out either by a doctor or a nurse. Of these, 412 were enrolled and 367 (89 %) were included in the analysis. An adequate view was obtained throughout in 53.4 % (93/177) of doctor endoscopies and 91.6 % (174/190) of nurse endoscopies (difference 38.2 %, 95 % CL 30.5 %, 47.2 %). In adequately viewed areas, the mean agreement between doctor and expert was 81.0 % and between nurse and expert it was 78.3 % (difference between the means 2.7 %, 95 % CL - 1.0 %, 6.4 %). There was no difference between doctors and nurses in the rate of biopsy performance (90.4 % and 91.1 %, respectively, P = 0.862). Nurses took longer (8.1 minutes vs. 4.6 minutes, P < 0.001) and used intravenous sedation more often (57.6 %, P = 0.027). Adequacy of view correlated positively with endoscopy duration ( P < 0.001), but diagnostic accuracy correlated inversely with duration ( P < 0.001). Neither adequacy or accuracy correlated significantly with use of intravenous sedation. CONCLUSIONS In endoscopies performed by nurses, the proportion of adequate examinations was much higher than that found for doctors. In areas with an adequate view, there is no significant difference in accuracy between nurses and doctors. Nurses can provide an accurate general diagnostic upper gastrointestinal endoscopy service as competently as doctors.

Abstract
SETTING A local government area in North West England with a significant population of Indian subcontinent (ISC) ethnic origin and a high incidence of tuberculosis. OBJECTIVE To assess whether return visits to the ISC are associated with an increased risk of developing clinical tuberculosis. METHODS Analysis of data prospectively obtained from ISC patients diagnosed with TB in 1998-2002 (cases) and age and sex matched ISC patients in two local GP practices (controls). RESULTS There is at best weak evidence of association between case status and whether individuals have had a repeat visit to the subcontinent within 3 years of notification in this cohort; odds ratio 1.26 (95% CI (0.95, 1.76)); Fishers exact test P=0.09.

Abstract
A quantitative description of dynamical systems requires the estimation of uncertain kinetic parameters and an analysis of their precision. A method frequently used to describe the confidence intervals of estimated parameters is based on the Fisher-Information-Matrix. The application of this traditional method has two important shortcomings: (i) it gives only lower bounds for the variance of a parameter if the solution of the underlying model equations is non-linear in parameters. (ii) The resulting confidence interval is symmetric with respect to the estimated parameter. Here, we show that by applying the bootstrap method a better approximation of (possibly) asymmetric confidence intervals for parameters could be obtained. In contrast to previous applications devoted to non-parametric problems, a dynamical model describing a bio-chemical network is used to evaluate the method.

Abstract
Intraductal papillary neoplasms (IPNs) of breast form a wide spectrum of pathological changes with benign intraductal papilloma occupying one end of the spectrum and papillary carcinoma at the other end. Intraductal papillomas are known to occur anywhere within the ductal system and are broadly classified into central and peripheral types. Intraductal papillary carcinoma is an uncommon ductal malignancy forming papillary structures, and these lesions characteristically lack the myoepithelial layer present in benign papillary neoplasms. Three basic patterns of IPNs are recognized on ultrasound - intraductal mass with or without ductal dilatation, intracystic mass and a predominantly solid pattern with the intraductal mass totally filling the duct. Benign papillomas are known to exhibit calcifications which tend to be extremely dense and coarse. IPNs are highly vascular tumours and have a propensity to bleed spontaneously. A distinct vascular pedicle is identified within the central core of IPNs, with branching vessels arborising within the mass. In an older age group, presence of a large solid component and evidence of spontaneous intracystic bleed are more suggestive of papillary carcinomas than benign papillomas. We have serially studied 42 cases of intraductal papillary neoplasms with sonomammography and mammography from 2001 to 2004.
