Abstract
Xylene customarily has been used as a clearing agent for routine tissue processing. Because xylene is a relatively hazardous solvent, laboratories are under pressure to seek less toxic alternatives for routine use. We prepared 30 paired soft tissue specimens for routine histopathological evaluation using conventional xylene and xylene-free methods to evaluate and compare their efficacy for fixation, processing, embedding, staining and turnaround time. All specimens were measured before and after processing. Three pathologists evaluated and scored the histological sections. Tissue shrinkage was greater when using the xylene method compared to the xylene-free method. The quality of tissue sections including tissue architecture; quality of staining; preservation of epithelial, fibrous, glandular, muscle and adipose tissue; inflammatory cells; and vascular tissue was better after using the xylene method, but differences were not statistically significant. Xylene-free method produced adequate results that nearly equaled the xylene method. Added advantages included cost effectiveness, better working atmosphere and decreased toxicity.

Abstract
This review provides an update on the incidence, diagnosis, predictors, implications and strategies of prevention of renal function impairment in patients undergoing intraarterial administration of iodinated contrast media. New criteria to timely and accurately diagnose clinically significant renal injury related to contrast media exposure are discussed. Special focus is pointed on the critical appraisal of the existing hydration regimens and the novel modalities to prevent contrast induced nephropathy including pharmacological and non-pharmacological strategies.

Abstract
The survival of transplant recipients is significantly lower than age-matched controls in the general population. The aim of this study was to analyze the trends in mortality of renal allograft recipients at our centre. We retrospectively analyzed data from all patients who were transplanted between October 1988 and June 2010 and were followed at our center. Patients were considered to have death with graft function (DWGF) if death was not preceded by return to dialysis or re-transplantation. The study included 98 renal allograft recipients (male : female – 7.99 : 1). The mean recipient and donor ages were 35.06 ± 11.84 (range: 15–69) and 41.17 ± 10.44 (range: 22–60) years, respectively. Basic kidney diseases were CGN (chronic glomerulonephritis) (60.20%), CIN (chronic interstitial nephritis) (15.31%), DN (diabetic nephropathy) (8.16%), ADPKD (autosomal dominant polycystic kidney disease) (2.04%) and others (14.29%). They were followed up for a mean 79.91 ± 60.05 patient-months. Mortality occurred in 25 (25.51%) patients (male : female – 4 : 1). Causes of death were sepsis/infection (36%), coronary artery disease (28%), CVA (8%), failed graft (4%), and rest unknown (24%). DWGF was 88% of total death and contributed to 78.57% of total graft loss. Overall patient survival at 1, 5, 10, and 15 years were 90.8%, 80.2%, 65.6%, and 59.1%, respectively (Kaplan–Meier analysis). Those who died exhibited significant differences in recipient's age (median 40 years vs 31 years, P=0.007), pretransplantation hypertension (HTN) (100% vs 65.75%, P<0.001), post-transplant infection (76% vs 42.47%, P=0.005), coronary artery disease (28% vs 1.37%, P<0.001), and serum creatinine at last follow up (median 2.3mg/dL vs 1.56mg/dL, P=0.003). Cardiovascular disease, in addition to infection, is an important cause of death during the first 15 years following renal transplantation even in nondiabetic recipients. Death with functioning graft is of concern.

Abstract
BACKGROUND & OBJECTIVES Prostate cancer (CaP) is the fifth most common cancer among Indian men. Tumour protein p53 (TP53) gene increases the fidelity of DNA replication and homologous recombination by transcriptional transactivation of mismatch repair (MMR) genes. DNA repair thus has a potential role in molecular carcinogenesis of CaP. The aim of the present study was to identify mutations, and polymorphisms in TP53 gene and MMR protein expression in CaP in Indian male population. METHODS TP53 codon 72 polymorphism was analysed in 105 CaP, 120 benign prostatic hyperplasia (BPH) cases and 106 normal controls. Mutational analysis of TP53 was done in DNA extracted from formalin fixed paraffin embedded tissue of 80 CaP and 24 BPH cases. Expression of MMR proteins viz. hMLH1, hMSH2, hPMS1 and hPMS2 was studied in 80 CaP, 15 prostatic intraepithelial neoplasia (PIN) and 15 BPH cases. RESULTS A somatic C/A variation at the intronic boundary of exon 7 in TP53 gene was observed in one each biopsy samples from CaP and BPH. A significant association of codon 72 TP53 Pro/Pro genotype was observed with the risk of CaP (OR, 2.59, P=0.02) and BPH (OR, 6.27, P<0.001). Immunohistochemical analysis of MMR proteins showed maximum loss of hPMS1 expression in cases of CaP and PIN while no loss in expression of MMR proteins was observed in BPH cases. The study also identified a significant loss of hPMS2 protein in poorly differentiated tumours (Gleason score >7) than in well differentiated tumours (Gleason score 3-6) (P<0.05). INTERPRETATION & CONCLUSIONS The results of the present study demonstrate that TP53 codon 72 polymorphism plays significant role in the pathogenesis and susceptibility to CaP and BPH. Also, an aberrant MMR protein expression could be involved in progression of prostate cancer through PIN, early CaP to aggressive CaP. The loss of hPMS2 protein expression may serve as a marker for progression of CaP.

Abstract
OBJECTIVE To establish the natural history of radiographic knee osteoarthritis (OA) over 14 years in a community-based cohort. METHODS We examined women from the Chingford Women's Study, a community-based cohort followed up for more than 14 years. We selected women for whom bilateral radiographs of the knees (with the legs in full extension) were obtained at approximately 5-year intervals. Radiographs were scored for OA in a blinded manner, using Kellgren/Lawrence (K/L) grades. Descriptive statistics and odds ratios (ORs) were used to compare the incidence, worsening, and progression of radiographic knee OA. RESULTS A complete radiography series was available for 561 of the original 1,003 subjects enrolled in the study. The median age of these subjects at baseline was 53 years (interquartile range 48-58 years). At baseline, 13.7% of the subjects had radiographic knee OA (K/L grade≥2) in at least one knee, and the prevalence increased to 47.8% by year 15. The annual cumulative incidence of radiographic knee OA was 2.3% between baseline and year 15. The annual rates of disease progression and worsening between baseline and year 15 were 2.8% and 3.0%, respectively. Subjects with a K/L grade of 1 at baseline were more likely to experience worsening by year 15 compared with subjects with a baseline grade of 0 (OR 4.5, 95% confidence interval 2.7-7.4). CONCLUSION This is the longest natural history study of radiographic knee OA to date. The results showed relatively low rates for the incidence and progression of radiographic knee OA; more than half of all subjects had no radiographic evidence of knee OA over a 15-year period of time. Subjects with a baseline K/L grade of 1 were more likely than subjects with other baseline K/L grades to experience worsening of knee OA.

Abstract
Controversy continues to surround the management of patients with an open fracture of the lower limb and an associated vascular injury (Gustilo type IIIC). This study reports our 15-year experience with these fractures and their outcome in 18 patients (15 male and three female). Their mean age was 30.7 years (8 to 54) and mean Mangled Extremity Severity Score (MESS) at presentation was 6.9 (3 to 10). A total of 15 lower limbs were salvaged and three underwent amputation (two immediate and one delayed). Four patients underwent stabilisation of the fracture by external fixation and 12 with an internal device. A total of 11 patients had damage to multiple arteries and eight had a vein graft. Wound cover was achieved with a pedicled flap in three and a free flap in six. Seven patients developed a wound infection and four developed nonunion requiring further surgery. At a mean follow-up of five years (4.1 to 6.6) the mean visual analogue scale for pain was 64 (10 to 90). Depression and anxiety were common. Activities were limited mainly because of pain, and the MESS was a valid predictor of the functional outcome. Distal tibial fractures had an increased rate of nonunion when associated with posterior tibial artery damage, and seven patients (39%) were not able to return to their previous occupation.

Abstract
The genes involved in androgen pathway and metabolism have been reported to contribute considerably to prostate carcinoma (CaP) risk. The present study investigated the association of androgen receptor (AR), prostate-specific antigen (PSA or KLK3), and cytochrome P450 (CYP19) gene polymorphisms in CaP (n=105) and benign prostatic hyperplasia (BPH) (n=120) in comparison to normal healthy controls (n=106) in an Indian population. We also evaluated the functional consequences of these gene variants on AR and PSA mRNA expression. Significant association of short AR CAG repeats (≤24) with risk of CaP (odds ratios [OR]=2.98, p<0.001) and BPH (OR=1.96, p=0.01) was observed; however, CYP19 gene polymorphism was not found to be associated with disease phenotype (p>0.05). PSA G-158A SNP was found to be significantly associated with risk of CaP (AA: OR=2.68, p=0.016 and GA: OR=2.07, p=0.018) p-trend 0.031 and BPH (AA: OR=3.46, p<0.001 and GA: OR=2.47, p=0.03) p-trend 0.009, respectively. PSA G-158A genotype independently increased the risk of developing BPH (OR=16.37, p<0.001), irrespective of AR CAG repeat length. Using quantitative real-time polymerase chain reaction, we found a significant upregulation of AR and PSA mRNA expression in CaP comparison to BPH. While short AR CAG (≤24) repeats were associated with higher AR mRNA expression in CaP (p=0.002), the PSA SNP did not correlate with its mRNA expression. Interestingly, significantly higher risk estimates for CaP were observed for the combined analysis of short AR CAG and CYP19 genotypes (A2A2) (OR=7.18, p<0.001) or A2A3 (OR=7.60, p=0.004). Our results suggest significant association of androgen signaling gene polymorphisms with risk of CaP and BPH and provide evidence for a putative functional role of AR CAG repeat in regulating its mRNA expression and warrant the need of larger studies in the Indian population to confirm our results.

Abstract
We report on the first realistic ab initio calculation of a hadronic weak decay, that of the amplitude A(2) for a kaon to decay into two π mesons with isospin 2. We find ReA(2)=(1.436±0.063(stat)±0.258(syst))10(-8) GeV in good agreement with the experimental result and for the hitherto unknown imaginary part we find ImA(2)=-(6.83±0.51(stat)±1.30(syst))10(-13) GeV. Moreover combining our result for ImA(2) with experimental values of ReA(2), ReA(0), and ε'/ε, we obtain the following value for the unknown ratio ImA(0)/ReA(0) within the standard model: ImA(0)/ReA(0)=-1.63(19)(stat)(20(syst)×10(-4). One consequence of these results is that the contribution from ImA(2) to the direct CP violation parameter ε' (the so-called Electroweak Penguin contribution) is Re(ε'/ε)(EWP)=-(6.52±0.49(stat)±1.24(syst))×10(-4). We explain why this calculation of A(2) represents a major milestone for lattice QCD and discuss the exciting prospects for a full quantitative understanding of CP violation in kaon decays.

Abstract
OBJECTIVE To describe the temporal patterns of knee pain in a community-based cohort over 12 years. METHODS Data on self-reported knee pain at 4 time points over 12 years were analyzed in participants from the Chingford Women's Study of osteoarthritis (OA) and osteoporosis. Pain status was defined as any pain in the preceding month and pain on most days in the preceding month. This status was used to classify participants according to pain patterns of asymptomatic, persistent, incident, or intermittent pain. Multinomial logistic regression was used to identify baseline predictors for each pain pattern. RESULTS Among the 489 women with complete followup data, the median age at baseline was 52 years (interquartile range [IQR] 48-58 years), the median body mass index (BMI) was 24.39 kg/m(2) (IQR 22.46-27.20), and 11.7% of the women had a Kellgren/Lawrence radiographic OA severity grade of ≥2 in at least one knee. Among subjects reporting any pain in the preceding month versus those reporting pain on most days in the preceding month, 9% versus 2% had persistent pain, 24% versus 16% had incident pain, and 29% versus 18% had intermittent pain. A higher BMI was predictive of persistent pain (odds ratio [OR] 1.14, 95% confidence interval [95% CI] 1.04-1.25) and incident pain (OR 1.10, 95% CI 1.02-1.18). The presence of radiographic knee OA was predictive of persistent pain (OR 3.70, 95% CI 1.34-10.28; P = 0.012), and reported knee injury was predictive of both persistent pain (OR 4.13, 95% CI 1.34-12.66; P = 0.013) and intermittent pain (OR 4.25, 95% CI 1.81-9.98; P = 0.001). CONCLUSION Significant variability in the temporal fluctuation of self-reported knee pain was seen in this community-based prospective study over a period of 12 years, with few women consistently reporting knee pain at each time point. Distinct baseline predictors for each pain pattern were identified and may explain the observed heterogeneity of self-reported knee pain when pain status is measured at only one time point.

Abstract
OBJECTIVE To examine longitudinal patterns in body mass index (BMI) over 14 years and its association with knee pain in the Chingford Study. METHODS We studied a total of 594 women with BMI data from clinic visits at years (Y) 1, 5, 10, and 15. Knee pain at Y15 was assessed by questionnaire. Associations between BMI over 14 years and knee pain at Y15 were examined using logistic regression. RESULTS BMI significantly increased from Y1 to Y15 (P < 0.0005) with medians (interquartile ranges) of 24.5 kg/m(2) (22.5-27.2 kg/m(2) ) and 26.5 kg/m(2) (23.9-30.1 kg/m(2) ), respectively. At Y15, 45.1% of subjects had knee pain. A greater BMI at Y1 (odds ratio [OR] 1.34, 95% confidence interval [95% CI] 1.05-1.69), at Y15 (OR 1.34, 95% CI 1.10-1.61), and change in BMI over 15 years (OR 1.40, 95% CI 1.00-1.93) were significant predictors of knee pain at Y15 (P < 0.05). BMI change was associated with bilateral (OR 1.61, 95% CI 1.05-1.76, P = 0.024) but not unilateral knee pain (OR 1.22, 95% CI 0.73-1.76, P = 0.298). The association between BMI change and knee pain was independent of radiographic knee osteoarthritis (OA). The strength of association between BMI and knee pain at Y15 was similar during followup measurements. CONCLUSION Over 14 years, a higher BMI predicts knee pain at Y15 in women, independently of radiographic knee OA. When adjusted, the association was significant in bilateral, not unilateral, knee pain, suggesting alternative pathologic mechanisms may exist. The longitudinal effect of BMI on knee pain at Y15 is equally important at any time point, which may assist reducing the population burden of knee pain.

Abstract
The large mass of the ninth pseudoscalar meson, the η', is believed to arise from the combined effects of the axial anomaly and the gauge field topology present in QCD. We report a realistic, 2+1-flavor, lattice QCD calculation of the η and η' masses and mixing which confirms this picture. The physical eigenstates show small octet-singlet mixing with a mixing angle of θ=-14.1(2.8)°. Extrapolation to the physical light quark mass gives, with statistical errors only, mη=573(6) MeV and mη'=947(142) MeV, consistent with the experimental values of 548 and 958 MeV.

Abstract
Polymorphisms in genes encoding detoxification enzymes have been suggested as susceptibility factors for many solid tumors. However, their association with hematological malignancies is controversial. A case-control study was done to determine the association between glutathione S-transferase M1 (GSTM1), GSTT1, GSTP1, EPHX1, and p53 codon 72 polymorphisms as risk factors in 120 adult acute myeloid leukemia (AML) cases and 202 healthy controls by polymerase chain reaction-restriction fragment length polymorphism techniques. Data were analyzed using χ(2) and conditional logistic regression model. None of the polymorphisms studied alone was associated with increased risk for AML. However, the frequency of GSTT1 null genotype was higher among controls (28.7%) than AML cases (21.6%), which showed a protective effect of the null genotype (odds ratio = 0.58, 95% confidence interval: 0.33-1.05, p = 0.07). In a combined analysis, both EPHX1 (His113His) and GSTP1 (Ile/Val) genes imparted a fourfold risk for adult AML but did not reach statistical significance (odds ratio = 4.22, 95% confidence interval: 0.992-17.99, p = 0.05). These findings suggest that the etiology of adult AML cannot be explained by polymorphism at a single locus, perhaps because of complexity involved in the metabolism of diverse xenobiotic compounds, and therefore, multiple gene-gene interactions should be investigated to predict the risk of AML.

Abstract
The aim of this study was to compare the efficacy of ceftriaxone plus vancomycin (Vancoplus) versus ceftriaxone alone against cephalosporin resistant methicillin-resistant Staphylococcus aureus (MRSA) strain by using meningitis mice model. The MRSA strain ATCC 43300 was used to induce meningitis in mice. The mice were fed standard pelleted diet and water ad libitum. The test room was air conditioned with temperature 23 +/- 2 degrees C, humidity 65+/- 5% and with artificial fluorescent light 10-14 hrs. of light and dark, respectively. Twenty four mice were divided into four group containing six rats in each group. The ceftriaxone group received 28.57 mg/Kg body weight/day and the vancoplus group received 42.8 mg/Kg body weight/day and control as well as infected group received normal saline. The bacterial susceptibility test in CSF was performed for cephalosporin resistance MRSA strain by determining the lytic zone for the vancoplus and ceftriaxone antibiotic. The lytic zone was more in vancoplus as compared to ceftriaxone. It was also found that activities of antioxidant enzymes such as catalase were significantly increased (p<0.001) along with decreased (p<0.001) in lipid peroxidation (malonaldialdehyde) level in CSF of vancoplus treated group as compared to infected as well as ceftriaxone resistance group and come back to normal level. It was concluded that vancoplus beneficial for the patients who suffered from cephalosporin resistant MRSA bacterial strain.

Abstract
Pneumonia is a severe infection that causes high morbidity and mortality rate worldwide. It is caused by Klebsiella pneumoniae, which generally causes upper respiratory tract infection. In case of such type of infection, levels of oxidant and antioxidant become imbalanced, which may contribute to lung injury. The present study was planned to evaluate the status of oxidant and antioxidant enzyme activities in plasma and lung tissue of pneumonia-infected rats model. Animals were randomly distributed into 3 groups of 8 rats each: groups I (control, normal saline treated), II (infected group), and III (infected + treated group). The findings showed that there was significant increase (P < .001) in body temperature along with decreased body weight in the infected group as compared to the control group. Similarly, all the activities of antioxidant enzymes (superoxide dismutase [SOD], catalase) were significantly decreased along with increased malonaldialdehyde (MDA) levels in plasma and lung tissue of the infected group as compared to the control group. These enzyme activities along with MDA levels were improved and came back near to normal level after administration of cefepime plus amikacin (potentox) for 7 days in group III. These studies concluded that fixed-dose combination of potentox improved oxidant and antioxidant levels in pneumonia infection.
