Abstract
A total maximum daily load (TMDL) for oxygen demanding substances is being implemented in the San Joaquin River (SJR) in California (USA) due to frequently occurring low dissolved oxygen conditions. The SJR is a eutrophic river, heavily impacted by agriculture. A mass balance was developed to identify the sources of oxygen-demanding substances and nutrients to the river with the objective of providing a scientific basis for management actions needed to meet TMDL requirements. Data were collected for flow and water quality and mass loads calculated for sites within the main stem of the SJR, river inputs (tributaries), and diversions in the study area. Using a quadrant analysis, tributary flows and loads are ranked to identify targets for water quality improvement efforts. Additionally, all mass loads were summed (inputs minus diversions) and compared with observed loads at the downstream limit of the study area. The mass balance analysis identifies major contributors of mass loads and mass balance closure is assessed for each constituent. These analysis methods inform the TMDL process which includes a load allocation, and is useful for determining locations for implementation of improvement projects needed to improve the health of the river.

Abstract
Defining mechanisms that generate intratumour heterogeneity and branched evolution may inspire novel therapeutic approaches to limit tumour diversity and adaptation. SETD2 (Su(var), Enhancer of zeste, Trithorax-domain containing 2) trimethylates histone-3 lysine-36 (H3K36me3) at sites of active transcription and is mutated in diverse tumour types, including clear cell renal carcinomas (ccRCCs). Distinct SETD2 mutations have been identified in spatially separated regions in ccRCC, indicative of intratumour heterogeneity. In this study, we have addressed the consequences of SETD2 loss-of-function through an integrated bioinformatics and functional genomics approach. We find that bi-allelic SETD2 aberrations are not associated with microsatellite instability in ccRCC. SETD2 depletion in ccRCC cells revealed aberrant and reduced nucleosome compaction and chromatin association of the key replication proteins minichromosome maintenance complex component (MCM7) and DNA polymerase δ hindering replication fork progression, and failure to load lens epithelium-derived growth factor and the Rad51 homologous recombination repair factor at DNA breaks. Consistent with these data, we observe chromosomal breakpoint locations are biased away from H3K36me3 sites in SETD2 wild-type ccRCCs relative to tumours with bi-allelic SETD2 aberrations and that H3K36me3-negative ccRCCs display elevated DNA damage in vivo. These data suggest a role for SETD2 in maintaining genome integrity through nucleosome stabilization, suppression of replication stress and the coordination of DNA repair.

Abstract
Archaea are unique microorganisms that are present in ecological niches of high temperature, pH and salinity. A total of 157 archaea were obtained from thirteen sediment, water and rhizospheric soil samples collected from Rann of Kutch, Gujarat, India. With an aim to screen phosphate solubilizing archaea, a new medium was designed as Haloarchaea P Solubilization (HPS) medium. The medium supported the growth and P solubilization activity of archaea. Employing the HPS medium, twenty isolates showed the P-solubilization. Phosphate solubilizing archaea were identified as seventeen distinct species of eleven genera namely Haloarcula, Halobacterium, Halococcus, Haloferax, Halolamina, Halosarcina, Halostagnicola, Haloterrigena, Natrialba, Natrinema and Natronoarchaeum. Natrinema sp. strain IARI-WRAB2 was identified as the most efficient P-solubilizer (134.61 mg/L) followed by Halococcus hamelinensis strain IARI-SNS2 (112.56 mg/L). HPLC analysis detected seven different kinds of organic acids, namely: gluconic acid, citric acid, formic acid, fumaric acid succinic acid, propionic acid and tartaric acid from the cultures of these isolates. These phosphate solubilizing halophilic archaea may play a role in P nutrition to vegetation growing in these hypersaline soils. This is the first report for these haloarchaea to solubilize considerable amount of P by production of organic acids and lowering of pH.

Abstract
Post-renal biopsy bleeding refractory to angioembolization usually requires graft nephrectomy as a life-saving measure. Gelatin-thrombin hemostatic matrix injection in the needle tract is a novel attempt to control bleeding in such cases and to salvage the allograft. We hereby describe two cases of post-graft biopsy bleed. Both these patients continued to bleed even after angioembolization. They were shifted to the operating room upon developing hypotension, having received multiple blood transfusions with the intention of performing graft nephrectomy to save their lives. However, bleeding was successfully controlled by using Gelatin-thrombin hemostatic matrix injection in the biopsy needle tract. Patients improved hemodynamically after the procedure. Graft function returned to normal in both the cases. At an average follow-up of 10.4 months, both the patients have shown stable graft functions.

Abstract
The prevalence of obesity is rising globally and in India. Overweight, obesity and related diseases need to be delineated in Asian Indian women. A literature search was done using key words like 'obesity', 'Asian Indian women', 'body fat distribution', 'type 2 diabetes', 'fertility', 'polycystic ovarian disease', metabolic syndrome', 'cardiovascular disease', 'non-alcoholic fatty liver disease', 'gender', 'sex' and 'prevalence' up to September 2012 in Pubmed and Google Scholar search engines. This review highlights the Asian Indian body composition with regards to obesity and provides a collated perspective of gender-specific prevalence of the co-morbidities. Recent data show that women (range of prevalence of overweight and obesity from different studies 15-61%) have higher prevalence of overweight and obesity as compared with men (range of prevalence of overweight and obesity from different studies 12-54%) in India and that obesity is increasing in the youth. The prevalence of overweight and obesity in both men and women steeply rose in a Punjabi community from Jaipur. Importantly, prevalence of abdominal obesity has been consistently higher in women than in men. The lowest prevalence (6.0%) of type 2 diabetes mellitus in women is reported from South India (rural Andhra Pradesh; 2006) and the highest (14.0%) by the National Urban Diabetes Survey (2001). Although the clustering of cardiovascular disease risk factors was generally high, it increased further in post-menopausal women. There are a number of factors that predispose Indian women to obesity; sedentary behaviour, imbalanced diets, sequential and additive postpartum weight gain and further decrease in physical activity during this period and cultural issues. In view of these data, preventive measures should be specifically targeted to Indian women.

Abstract
BACKGROUND Over the past two decades, there is increasing emphasis being placed upon providing family-centred care (FCC) in paediatric oncology settings. However, there is a lack of knowledge of FCC in paediatric oncology from the perspectives of immigrant parents. The purpose of this paper is to describe Chinese and South Asian immigrant parents' experiences of FCC in paediatric oncology settings in Canada. METHODS This study adopted a constructivist grounded theory approach. Fifty first generation Chinese and South Asian parents of children with cancer who were at least 6 months post-diagnosis were recruited from six Canadian paediatric oncology centres. Interviews were conducted in English, Cantonese, Mandarin, Urdu, Punjabi or Hindi, and transcribed into English. Analysis involved line-by-line, focused and theoretical coding, and the use of the constant comparison method. RESULTS Findings indicated that overall parents were highly satisfied with the care and services they received, and their experiences were reflective of the key elements of FCC. However, there were some areas of concern identified by participants: parents not perceiving themselves as a member of the medical team; inconsistency in the quality and co-ordination of services among healthcare providers; disrespectful and mechanical manner of a few healthcare providers; and parents' discomfort with healthcare providers communicating sensitive health-related information directly with their child. CONCLUSIONS In order to successfully provide family-centred services to immigrant parents of children with cancer, better communication of the elements of FCC between healthcare staff and families is needed to negotiate a clear role for the parents as partners of the healthcare team. Moreover, a better understanding of how family relationships are structured in immigrant families will assist healthcare providers to balance the best interests of the child with that of the family as a unit.

Abstract
Gingival overgrowth is a common adverse effect of therapy with Phenytoin, having important medical and cosmetic implications. Poor periodontal hygiene is an important risk factor for severity of Phenytoin-induced gingival overgrowth (PIGO), which is a time-dependent process. There is complex interplay of altered fibroblast biology, connective tissue turnover, inflammatory processes, and growth factors on a background of genetic susceptibility to produce increase in various components of interstitial matrix in PIGO tissue. Treatment options have included change of PHT to another anti-seizure drug, measures to improve periodontal hygiene and gingivectomy. There is conclusive evidence that folic acid supplementation significantly decreases the incidence of PIGO.

Abstract
Abstract
Background
The aim was to compare percutaneous transluminal angioplasty (PTA), a supervised exercise programme (SEP) and combined treatment (PTA plus SEP) for intermittent claudication due to femoropopliteal arterial disease.
Methods
Consenting patients with femoropopliteal arterial lesions were randomized to one of three treatment arms: PTA, SEP, or PTA plus SEP. All patients received optimal medical treatment. Patients were assessed at baseline and 1, 3, 6 and 12 months after intervention. Clinical (ankle pressures, walking distances, symptoms) and quality-of-life (QoL) outcomes (Short Form 36, VascuQol) were analysed.
Results
A total of 178 patients (108 men, median age 70 years) were included. All three treatment groups demonstrated significant clinical and QoL improvements. One year after PTA (60 patients, 8 withdrew), 37 patients (71 per cent) had improved (16 mild, 16 moderate, 5 marked), nine (17 per cent) showed no improvement and six (12 per cent) had deteriorated. After SEP (60 patients, 14 withdrew), 32 patients (70 per cent) had improved (19 mild, 10 moderate, 3 marked), six (13 per cent) showed no improvement and eight (17 per cent) had deteriorated. After PTA plus SEP (58 patients, 11 withdrew), 40 patients (85 per cent) had improved (18 mild, 20 moderate, 2 marked), seven (15 per cent) showed no improvement and none had deteriorated. On intergroup analysis, PTA and SEP alone were equally effective in improving clinical outcomes, although the effect was short-lived. PTA plus SEP produced a more sustained clinical improvement, but there was no significant QoL advantage.
Conclusion
For patients with intermittent claudication due to femoropopliteal disease, PTA, SEP, and PTA plus SEP were all equally effective in improving walking distance and QoL after 12 months.

Abstract
There are conflicting data regarding the comparative efficacy of mycophenolate mofetil (MMF) versus azathioprine (AZA) as maintenance immunosuppressive agent in kidney transplantation. The data are even less in combination with tacrolimus (TAC) in living donor kidney transplantation. A total of 205 living donor kidney transplants, on TAC-based triple drug immunosuppression were included in the study. A total of 113 patients received AZA and rest 92 were on MMF based protocol. TAC levels were monitored and graft biopsy was done whenever rejection was suspected. The outcomes were evaluated in terms acute rejection (AR) episodes at 1 year, infections, renal function, graft loss, and death between two groups. The study group comprised 163 males (79.5%) and 42 (20.5%) females. The mean age of patients was 42.4±11.8 years in the AZA group and 39.4 ±13.4 in the MMF group (P=0.09). The mean duration of follow-up was 491.7±240.7 and 478.8±334.4 days respectively in the AZA and MMF groups (P=0.75). Thirty-seven of 92 (40.2%) patients in the MMF group and 70/113 (61.9%) patients in the AZA group received IL-2 RAb induction (P=0.002). 32 patients (15.6 %) developed AR within a year. The incidence of AR was similar in patients who received MMF (12/92, 13%) and those who received AZA (20/113, 17.5%), (P=0.36). There was no difference in the incidence of AR in the subgroup of patients who received IL-2 RAb compared to those who did not receive induction in the two groups (5/37 vs. 7/55 in the MMF group and 10/70 vs. 10/43 in the AZA group, P=0.72). The incidence of infections was similar in the two groups (19/92, 20.6% vs. 25/113, 22.1%, P=0.79). Three patients developed CMV disease, of which two were in the MMF group. Graft loss occurred in 7/205 (3.4%) and death in 8/205 (3.9%) patients. Six of eight patients who died had functioning grafts. The rate of graft loss (3/92 vs. 4/113, P=0.97) and death (5/92 vs. 3/113, P=0.27) was similar in two groups. The overall patient survival was 94.5% and death censored graft survival was 97.4%. Cost comparison suggests AZA to be 6-10 times cheaper than MMF. This study suggests that, in tacrolimus-based immunosuppression, azathioprine may be as good as MMF as maintenance immunosuppressive drug in living donor kidney transplantation. It is also a more cost-effective immunosuppression.

Abstract
The aim of the study was to study the distribution of angiotensin-converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism, and its association with steroid responsiveness in children with idiopathic nephrotic syndrome (INS). One hundred twenty-five children with INS were classified into two groups: steroid-sensitive nephrotic syndrome (SSNS: n = 90) and steroid-resistant nephrotic syndrome (SRNS: n=35). The control group consisted of 150 unrelated healthy children. Genomic DNA was extracted from peripheral leucocytes by the standard salting-out method. ACE genotyping was performed and ACE genotypes DD, ID, and II were compared between different groups. The frequency distribution of the DD genotype was significantly increased in children with INS compared to control subjects (P = 0.0012) while the difference was not significant (P = 0.071) between SSNS and control subjects. The frequency distribution of the DD genotype was significantly high in the SRNS group compared to control subjects (P < 0.0001). The distribution of the DD genotype was high in SRNS compared to SSNS group patients (P = 0.016). In conclusion, the presence of the DD genotype may predict risk for steroid resistance in childhood INS.

Abstract
OBJECTIVE Gingival overgrowth is an important adverse effect of phenytoin (PHT) therapy, occurring in about half of the patients. This study aimed to evaluate the effect of oral folic acid supplementation (0.5 mg/day) for the prevention of PHT-induced gingival overgrowth (PIGO) in children with epilepsy aged 6-15 years on PHT monotherapy for 6 months. METHODS This was a randomized, double-blind, placebo-controlled trial conducted at a tertiary level hospital from May 2008 to June 2009. Children aged 6-15 years started on PHT monotherapy within last 1 month were eligible for inclusion. Preexisting gingival overgrowth, use of other folic acid antagonists, and macrocytic anemia were exclusion criteria. Trial subjects were randomized to receive either folic acid or placebo. The primary outcome measure was incidence of any degree of gingival overgrowth after 6 months of PHT monotherapy. The trial was registered with clinicaltrials.gov (NCT00781196). RESULTS A total of 120 children were recruited, 62 and 58, respectively, in folic acid and placebo arms. The 2 arms were comparable at baseline. Twenty-one percent of patients in the folic acid arm developed PIGO, as compared with 88% receiving placebo (p < 0.001). Absolute risk reduction of PIGO by folic acid was 67% (95% confidence interval 54%-80%), and relative risk reduction was 0.76. CONCLUSIONS Oral folic acid was found to decrease the incidence of PIGO in children on PHT monotherapy, in a statistically significant and clinically relevant manner. CLASSIFICATION OF EVIDENCE This study provides Class I evidence that folic acid supplementation, 0.5 mg/day, is associated with prevention of gingival overgrowth in children taking PHT monotherapy.
