Abstract
INTRODUCTION Post-operative astigmatism is one of the most important causes for diminution of vision after trabeculectomy. OBJECTIVE To evaluate the induced corneal astigmatism following trabeculectomy with the use of 8-0 silk suture. MATERIALS AND METHODS A prospective interventional study was done including 100 consecutive eyes of 84 patients who underwent trabeculectomy with the use of 8-0 silk suture. The postoperative induced astigmatism on the 1st post-operative day, 3rd week and after 6 months was determined. STATISTICS Vector analysis was performed on the data using a computerized method for calculating the surgically induced astigmatism (SIA) for each eye at every time point postoperatively. In order to analyze group changes, we also performed vector decomposition which gave us a mathematical expression of the changes in astigmatism "with the rule" (WTR) or "against the rule" (ATR). RESULTS The mean age of all the patients was 53.31 11.39 years. The mean 1st post-operative surgically induced astigmatism (SIA) was 2.73 D ( 99 degree ) which reduced to 0.41 D ( 58 degree) at the 3rd week and 0.43 ( 21 degree) at 6 months. The mean WTR astigmatism was 4.46 D and ART astigmatism was 1.42 D on the 1st post-operative day which was significantly high ( p less than 0.0001). At the 3rd week and 6 months WTR astigmatism ( 1.40 D and 1.08D ) and ATR astigmatism (1.27 D and 1.10 D) showed no significant changes (p=0.69,0.97 respectively. CONCLUSION Trabeculectomy with the use of 8/0 silk sutures showed significantly high 1st post-operative day SIA which nevertheless perished fast to a minimum amount at just 3 weeks.

Abstract
Nearly a thousand mutations mapping to 60 different loci have been identified in cerebellar ataxias. However, almost 50% of the cases remain genetically uncharacterized and there is a difference in prevalence as well as in the phenotypic spectrum of ataxia among various geographical regions. This poses a challenge for setting up a genetic panel for screening ataxia. In our ataxic cohort of 1014 families, 61% are genetically uncharacterized (UC). We investigated the potential of whole exome sequencing in conjunction with homozygosity mapping (HM) to delineate the genetic defects in three uncharacterized families with recessive inheritance each manifesting some unusual phenotype: (i) infantile onset ataxia with hearing loss (IOAH), (ii) Juvenile onset cerebellar ataxia with seizures (JCS) and (iii) Friedreich ataxia-like (FA-like). We identified a novel missense mutation in c10orf2 in the family with IOAH, compound heterozygous mutations in CLN6 in the family with JCS and a homozygous frame-shift mutation in SACS in the FA-like patient. Phenotypes observed in our families were concordant with reported phenotypes of known mutations in the same genes thus obviating the need for functional validation. Our study revealed novel variations in three genes, c10orf2, CLN6, and SACS, that have so far not been reported in India. This study also demonstrates the utility of whole exome screening in clinics for early diagnosis.

Abstract
Influenza A (H1N1) commonly known as swine flu, has covered a large part of the globe rapidly since the outbreak started in Mexico on 18th March, 2009. Given the rapid worldwide spread of the virus, it is important to identify the symptoms that require screening for influenza A(H1N1). Therefore, this study was planned to determine the clinical predictors of influenza A(H1N1) in the population of Kanpur city. Study sample comprised all cases with flu-like symptoms suspected of having influenza A(H1N1) whose nasopharyngeal samples had been sent for laboratory examination. Of the 119 samples sent to the laboratory, 34 were found to be positive for influenza A(H1N1). Best predictors found were fever with shortness of breath (positive predictive value=87.5%) followed by fever with cough without other cold like features (positive predictive value=68.6%). None of the clinical signs had all the attributes of a good predictor of influenza A(H1N1). Fever with cough was the most sensitive (70.6%) and fever with shortness of breath was the most specific indicator (98.8%). Therefore, it was concluded that symptoms like fever with cough without other cold like features and fever with shortness of breath should not be ignored and require expert medical attention for screening of influenza A(H1N1).

Abstract
In many areas, decreases in the stratospheric ozone layer have resulted in an increase in ultraviolet-B (UV-B, 280-315 nm) radiation reaching the Earth's surface. The present study was conducted to evaluate the interactive effects of supplemental UV-B (sUV-B) and mineral nutrients on a tuber crop, potato (Solanum tuberosum L. var Kufri Badshah), under natural field conditions in a dry tropical environment. The nutrient treatments were the recommended dose of NPK (F(o)), 1.5 times the recommended dose of NPK (F(1)), 1.5 times the recommended dose of N (F(2)) and 1.5 times the recommended dose of K (F(3)). The response of potato plants to sUV-B varied with nutrient treatment and concentration. sUV-B adversely affected growth, yield and quality of tubers, causing an increase in reducing sugars in the tubers and thus reducing the economic value. Growth and fresh weight of tubers was maximal with sUV-B at 1.5 times recommended NPK, but the dry weight of tubers were highest with the recommended NPK dose. Reducing sugar content was lower in potato plants treated with sUV-B and the recommended NPK than with sUV-B and 1.5 times the recommended NPK. This study thus clearly shows that growing potato with 1.5 times the recommended NPK or 1.5 times the recommended dose of N/K does not alleviate the sUV-B induced changes in yield and quality of tubers compared to the recommended NPK dose.

Abstract
BACKGROUND India has one of the most extensive health infrastructures- a three-tier hierarchical referral system- for the provision of effective and efficient health services to the majority of its population. In this study we have tried to evaluate the utilization of such a wide health infrastructure and the various factors affecting it. We have also tried to find the factors that motivated the patients to visit the present health facility and the key persons who motivated them to do so. METHODS Time bound cross-sectional study. SETTING Three types of referral health facilities in Lucknow District. PARTICIPANTS A total of 1265 patients were interviewed during the four months of the period of survey from these three types of referral health facilities. RESULTS The present study revealed that majority of the patients coming to all the three referral centres were the new patients (89%), about two-thirds of whom had come there directly. Overall, only one tenth of the patients attending the secondary and tertiary level public health facilities were referred by someone. Most of the indirect patients had self referred themselves. About eight and nine percent of the indirect and referred patients could reach the present site of treatment only after more than two years of rummaging and about 13% and 11% had spent more than ten thousand rupees respectively, which in some cases even amounted to lakh rupees. CONCLUSIONS The utilization of the referral system of the health care delivery in India needs to be augmented. Before planning future reforms such as decentralization, incorporation of the Indian system of Medicine, and other steps we need to develop mechanisms to see that the plans are materialized.

Abstract
BACKGROUND Gastrin has a role in gastrointestinal (GI) malignancy. This study provides pre-clinical evaluation of a novel, orally-active gastrin/cholecystokinin-2 receptor (CCK-2R) antagonist, Z-360. METHODS (125)I gastrin-17 (G17) displacement and G17-stimulated calcium assays were used in classical CCK-2R-transfected cell lines. Akt phosphorylation was assessed by Western blotting. Z-360 efficacy in vivo was evaluated in three human xenograft models, and microvessel density and apoptosis in these models were investigated by immunohistochemistry. RESULTS Z-360 inhibited (125)I G17 binding to cells expressing CCK-2R, and G17-stimulated signalling. Reduced Akt phosphorylation in an oesophageal cell-line treated with Z-360 was reversed by co-treatment with G17. Z-360 increased survival in a gastric ascites model (p=0.011) and decreased tumour growth in a hepatic metastasis model (81%, p=0.02). In an orthotopic pancreatic model, Z-360 combined with gemcitabine decreased final tumour weight compared to single agents (84%, p=0.002) and there was increased apoptosis and decreased microvessel density in ex vivo tumour tissue. CONCLUSIONS These results show that the orally-active CCK-2R antagonist, Z-360 has high sub-nM affinity for classical CCK-2R, is well tolerated in vivo and exerts an anti-tumour effect.

Abstract
This study investigated sonic hedgehog (Shh) signalling in gastric metaplasia in the insulin-gastrin (InsGas) hypergastrinaemic mouse +/− Helicobacter felis (H. felis) infection. Sonic hedgehog gene and protein expression was reduced in pre-metaplastic lesions from non-infected mice (90% gene reduction, P<0.01) compared to normal mucosa. Sonic hedgehog was reactivated in gastric metaplasia of H. felis-infected mice (3.5-fold increase, P<0.01) compared to pre-metaplastic lesions. Additionally, the Shh target gene, glioma-associated oncogene (Gli)-1, was significantly reduced in the gastric glands of InsGas mice (75% reduction, P<0.05) and reactivated with H. felis infection (P<0.05, base of glands, P<0.01 stroma of metaplastic glands). The ability of H. felis to activate the Shh pathway was investigated by measuring the effect of target cytokine, interleukin-8 (IL-8), on Shh expression in AGS and MGLVA1 cells, which was shown to induce Shh expression at physiological concentrations. H. felis induced the expression of NF-κB in inflammatory infiltrates in vivo, and the expression of the IL-8 mouse homologue, protein KC, in inflammatory infiltrates and metaplastic lesions. Sonic hedgehog pathway reactivation was paralleled with an increase in proliferation of metaplastic lesions (15.75 vs 4.39% in infected vs non-infected mice, respectively, P<0.001). Furthermore, Shh overexpression increased the growth rate of the gastric cancer cell line, AGS. The antiapoptotic protein, bcl-2, was expressed in the stroma of infected mice, along with a second Shh target gene, patched-1 (P=0.0001, stroma of metaplastic gland). This study provides evidence suggesting reactivation of Shh signalling from pre-metaplastic to advanced metaplastic lesions of the stomach and outlines the importance of the Shh pathway as a potential chemoprophylactic target for gastric carcinogenesis.

Abstract
Soil animals are considered as important contributors to soil fertility However, there is paucity of such information for harsh climatic conditions. Therefore, the below ground faunal density and frequency have been studied in relation to physicochemical properties of soil in Thar desert. The selected soil systems were Vigna radiata--Cuminum cyminum, grassland, flower garden and Zizyphus mauritiana. Acari and other soil arthropods exhibited seasonal variation in their populations. There were two population peaks, one in February/March and other in August/September. The highest population was in flower garden, whereas lowest was in Z. mauritiana field. It clearly indicates that the soil fauna population develops in different degrees. The relative density showed that the acarines were more prevalent in comparison to other soil arthropods. The prostigmatids exhibited maximum relative density in comparison to cryptostigmatids and mesostigmatids in all fields. Pauropus showed higher relative density among all other soil arthropods. Acari had higher frequency of occurrence, while the other soil arthropods indicated lower frequency of occurrence in all systems. The highest frequency of occurrence was recorded in July/August and the lowest in May/June. The soil temperature, moisture, organic carbon, total nitrogen and carbon/nitrogen ratio varied significantly throughout the year The fluctuations in physicochemical characteristics of soil greatly influenced below ground faunal density in different fields. A highly significant and positive correlation was obtained among different soil fauna groups. Faunal population showed a significant positive correlation with soil moisture, organic carbon and total nitrogen. The abiotic factors such as temperature, pH and C/N ratio showed negative correlation with moisture, organic carbon and total nitrogen. However, moisture, organic carbon and total nitrogen had positive correlation among themselves. The present study suggests that the plantation may be done for improvement of physicochemical and biological health of soil on a sustainable basis in desert.

Abstract
INTRODUCTION Trabeculectomy is a commonly used surgical treatment for glaucoma. PURPOSE To evaluate the effectiveness of combination of permanent and releasable scleral flap sutures to minimize the immediate postoperative complications of trabeculectomy. MATERIALS AND METHODS This study was carried out in Department of Ophthalmology, B P Koirala Institute of Health Sciences, Dharan, Nepal. Forty one eyes of 34 patients undergoing trabeculectomy were randomized to undergo either conventional trabeculectomy (Group A= 20 eyes) or trabeculectomy with combination of permanent and releasable scleral flap sutures (Group B =21 eyes). The parameters studied were intraocular pressure (IOP), anterior chamber depth (ACD) and surgical complications over a period of 6 weeks. RESULTS Significantly higher number of eyes belonging to group A (14 eyes) had shallower anterior chamber than group B (7 eyes) on first post operative day (p=0.042). Six eyes (30%) in group A had peripheral or central irido-corneal touch in early postoperative period as compared to only one in Group B. Hypotony was noted in 3 eyes in each group. Two patients in group A required reformation of anterior chamber. Other surgical complications in the two groups were similar. Both the groups had a significant drop in IOP following surgery. However, there was no significant difference in the IOP between the two groups after 6 weeks (Group A: 10.95 +/- 3.03 mmHg vs. Group B: 12.29 +/- 4.67 mmHg; p=0.87). There was a significant drop in IOP following removal of sutures (15.19 +/- 6.15 mmHg to 13.19 +/- 6.13 mmHg; p=006) in group B. CONCLUSION Use of combination of permanent and releasable scleral flap sutures is a safe technique that significantly reduces the incidence of immediate postoperative shallow anterior chamber after trabeculectomy.
