Background: Tremendous progress of imaging technique does not result in early diagnosis of gall bladder cancer. In search of effective, inexpensive and non-invasive tool tumour markers shows promise. Serum CA242, CA19.9 and CEA are evaluated for this purpose. Aim and objective: To evaluate diagnostic signicance of serum CA242, CA19.9 and CEAin gall bladder cancer either alone or in combination. Material and methods: It was an analytical cross sectional study done in Indira Gandhi Institute of medical Sciences. These markers were measured in 70 cases of gall bladder cancer and 70 healthycontrols. Serum CA242 was done by ELISA assay as per instruction given in pack insert (CD diagnostic). Serum CA19.9 and CEA were done by CLIA technique by Assess 2 analyser. Results: Mean value of these tumour marker were increased in gall bladder cancer group (p<0.001). CA19.9 was most sensitive tumourmarker (79.5%). Serum CA 242 was most specic test (83.3%) for diagnosis of gall bladder cancer among the three-tumour marker. On combination of tumour marker sensitivity (87.5%) and specicity (89.5%) were increased. In ROC curve analysis area under curve (AUC) for CA242 was highest. Conclusion: Combination of these tumour markers can be used as screening tool for gall bladder cancer.

Background: The aberrant alteration in Jab1 signalosome (COP9 Signalosome Complex Subunit 5) has been proven to be associated with the progression of several carcinomas. However the specific role and mechanism of action of Jab1 signalosome in carcinogenesis of gall bladder cancer (GBC) are poorly understood. Objective: The main objective of our study was to elucidate the role and mechanism of Jab1 signalosome in gall bladder cancer by employing siRNA. Methods: Jab1 overexpression was identified in gall bladder cancer tissue sample. The role of Jab1-siRNA approach in cell growth inhibition and apoptotic induction was then examined by RT-PCR, Western Blotting, MTT, ROS, Hoechst and FITC/Annexin-V staining. Results: In the current study, we have shown that overexpression of Jab1 stimulated the proliferation of GBC cells; whereas downregulation of Jab1 by using Jab1-siRNA approach resulted incell growth inhibition and apoptotic induction. Furthermore, we found that downregulation of Jab1 induces cell cycle arrest at G1 phase and upregulated the expression of p27, p53 and Bax gene. Moreover, Jab1-siRNA induces apoptosis by enhancing ROS generation and caspase-3 activation. In addition, combined treatment with Jab1-siRNA and gemicitabine demonstrated an enhanced decline in cell proliferation which further suggested increased efficacy of gemcitabine at a very lower dose (5μM) in combination with Jab1-siRNA. Conclusion: In conclusion, our study strongly suggests that targeting Jab1 signalosome could be a promising therapeutic target for the treatment of gall bladder cancer.

Background:Plant sterols have proven a potent anti-proliferative and apoptosis inducing agent against several carcinomas including breast and prostate cancers. Jab1 has been reported to be involved in the progression of numerous carcinomas. However, antiproliferative effects of sterols against Jab1 in gall bladder cancer have not been explored yet.Objective:In the current study, we elucidated the mechanism of action of stigmasterol regarding apoptosis induction mediated via downregulation of Jab1 protein in human gall bladder cancer cells.Methods:In our study, we performed MTT and Trypan blue assay to assess the effect of stigmasterol on cell proliferation. In addition, RT-PCR and western blotting were performed to identify the effect of stigmasterol on Jab1 and p27 expression in human gall bladder cancer cells. We further performed cell cycle, Caspase-3, Hoechst and FITC-Annexin V analysis, to confirm the apoptosis induction in stigmasterol treated human gall bladder cancer cells.Results:Our results clearly indicated that stigmasterol has up-regulated the p27 expression and down-regulated Jab1 gene. These modulations of genes might occur via mitochondrial apoptosis signaling pathway. Caspase-3 gets activated with the apoptotic induction. Increase in apoptotic cells and DNA were confirmed through annexin V staining, Hoechst staining, and cell cycle analysis.Conclusion:Thus, these results strongly suggest that stigmasterol has the potential to be considered as an anticancerous therapeutic agent against Jab1 in gall bladder cancer.

BackgroundIn 2012, ortho-toluidine (OT) was listed as a Group 1 carcinogen by the International Agency for Research on Cancer, based on epidemiologic observations in workers co-exposed to OT and aromatic amines. Between 2014 and 2017, 10 cases of bladder cancer (BC) were identified in Japanese males working at two plants of the same company manufacturing intermediates of organic dyes and pigments.ObjectiveTo describe the features of the BC epidemic at the plants.MethodsWe conducted a cross-sectional study of 76 OT and/or aromatic amine-exposed workers including the 10 BC cases at the plants in 2017. The co-exposed aromatic amines were para-toluidine, ortho-anisidine, aniline, 2,4-dimethylaniline, and/or ortho-chloroaniline. Details of each worker’s job-site histories were obtained from the company records. Past medical symptoms and histories were checked in physician interviews. The subjects were divided into the BC group (n=10) and the non-BC group (n=66) and compared. No quantitative exposure data were available. The surrogate level of exposure to each aromatic amine was calculated as the summed job-weight-month in each process in each job-year.ResultsThe mean ages of the non-BC and BC groups were 50 and 56 years and the durations of employment were 23 and 20 years, respectively. The smoking rate in both groups was 80%. Significantly higher rates of gross hematuria (70%) and cystitis (70%) were identified in the BC group’s past medical histories. In the BC group, the surrogate levels of exposure to OT were higher than those of exposures to other aromatic amines. The surrogate levels were high in the job processes of filtering, rinsing, drying and packing products.ConclusionsThe subjects with BC were associated with a high surrogate level of exposure to OT. OT-exposed workers with past histories of gross hematuria and cystitis need a careful follow-up.

Background: The present study highlights the occurrence of Incidental gallbladder carcinoma (IGBC) detected during histopathological examination in cholecystectomy specimens removed for cholelithiasis. Methods- This is a tertiary hospital based cross-sectional study of 500 cholecystectomy specimens removed during cholelithiasis. Relevant hospital records, histopathology slides and reports were reviewed, re-evaluated and studied. Results: 4(0.80%) cases of incidental gall bladder carcinoma (IGBC) were diagnosed from the histopathological evaluation (HPE) of 500 cholecystectomy specimens, constituting 0.80% of gall bladder specimens received during the study period. The age of the patients with IGBC ranged from 51-80 years. More females were affected than males with a M:F ratio of 1:3. Conclusion: Early detection of IGBC by histopathological examination would have a favourable impact on prognosis and management thereby increasing the survival outcome.

Determining gender is one of the most important procedure in forensics. Teeth are made of the most enduring mineralized tissues in the body, as such, they have an extraordinary resistance to putrefaction and the effects of external agents (physical, thermal, mechanical, chemical or biological) which makes them invaluable material for anthropological, genetic, odontologic and forensic examinations.i)To assess the degree of sexual dimorphism in maxillary canine using maxillary canine index, maxillary first molar and central incisor using mesiodistal (MD) and buccolingual/buccopalatal (BL) dimensions of the crown. ii) To determine the accuracy of maxillary canine index, first molar and central incisor dimensions (mesiodistal and buccolingual/buccopalatal) in determining sex.This study consisted of total 30 participants (males=15, females=15) of age group ranging from 20 to 35 yrs. Measurement of dimensions of selected teeth were performed on maxillary cast using digital Vernier caliper, resolution 0.01mm. Data thus obtained were analyzed statistically.The mean values of all the measurements in males were greater than females. There was statistical significant difference in mean value of bucco-lingual width of molar, mesiodistal width of canine (on left side, right side and average) and the inter-canine distance between males and females. The buccolingual width of molar showed the highest % of sexual dimorphism (5.33%) and the mesiodistal width of molar showed the least % of dimorphism (0.7%). Bucco-lingual width of molar posed the highest prediction accuracy for gender determination. We conclude that buccolingual width of maxillary first molar can be used to predict the gender when only teeth of maxillary arch are available for forensic examination.
