Abstract
Advanced glycation end products (AGEs) are glycated proteins or lipids formed endogenously in the human body or consumed through diet. Ultra-processed foods and some culinary techniques, such as dry cooking methods, represent the main sources and drivers of dietary AGEs. Tissue accumulation of AGEs has been associated with cellular aging and implicated in various age-related diseases, including type-2 diabetes and cardiovascular disease. The current review summarizes the literature examining the associations between AGEs and neurocognitive and mental health disorders. Studies indicate that elevated circulating AGEs are cross-sectionally associated with poorer cognitive function and longitudinally increase the risk of developing dementia. Additionally, preliminary studies show that higher skin AGE accumulation may be associated with mental disorders, particularly depression and schizophrenia. Potential mechanisms underpinning the effects of AGEs include elevated oxidative stress and neuroinflammation, which are both key pathogenetic mechanisms underlying neurodegeneration and mental disorders. Decreasing dietary intake of AGEs may improve neurological and mental disorder outcomes. However, more sophisticated prospective studies and analytical approaches are required to verify directionality and the extent to which AGEs represent a mediator linking unhealthy dietary patterns with cognitive and mental disorders.

Abstract
Manual segmentation of brain tumor is not only a tedious task that may bring human mistakes. An automatic segmentation gives results faster, and it extends the survival rate with an earlier treatment plan. So, an automatic brain tumor segmentation model, modified inception module based U-Net (IMU-Net) proposed. It takes Magnetic resonance (MR) images from the BRATS 2017 training dataset with four modalities (FLAIR, T1, T1ce, and T2). The concatenation of two series 3×3 kernels, one 5×5, and one 1×1 convolution kernels are utilized to extract the whole tumor (WT), core tumor (CT), and enhance tumor (ET). The modified inception module (IM) collects all the relevant features and provides better segmentation results. The proposed deep learning model contains 40 convolution layers and utilizes intensity normalization and data augmentation operation for further improvement. It achieved the mean dice similarity coefficient (DSC) of 0.90, 0.77, 0.74, and the mean Intersection over Union (IOU) of 0.79, 0.70, 0.70 for WT, CT, and ET during the evaluation.

Abstract
Background and Aims: Spinal anesthesia is the regional technique preferred for cesarean section and is usually administered using the traditional landmark technique. Ultrasonography of the spine appears to be helpful in locating the puncture site and increasing the success rate. The primary objective of this study was to assess the use of ultrasonogram in locating the lumbar interspinous space for spinal anesthesia in laboring parturients brought for elective cesarean section. Material and Methods: Sixty parturients scheduled to undergo elective cesarean section under spinal anesthesia were included in this prospective randomized controlled trial, after obtaining the institutional ethical clearance. In Group I, 30 patients received spinal anesthesia by landmark technique and in Group II, 30 patients underwent ultrasound-guided spinal anesthesia. The statistical analysis was done using SPSS software version 17 (SPSS Inc., Chicago, Illinois, USA) for Microsoft windows. Results: The time taken for spinal in Group I was longer than in Group II (62 ± 18s; 41 ± 11s; P = 0.0001). The number of attempts of needle insertion was significantly less in Group II (group I 1.86 ± 1.04: group II 1.06 ± 0.25). However, the total preparation time (28 8.30 ± 92 vs 804.73 ± 77; P = 0.0001) was more in the ultrasound-guided than in the landmark group. The patients had better satisfaction in group II. Conclusion: Preprocedural ultrasound is a useful tool for successful lumbar puncture in parturients as it minimizes the number of attempts of needle insertion and provides better patient satisfaction.

Abstract
AIM The performance of therapeutic procedures in lower gastrointestinal endoscopy (LGI) can be challenging and carries an increased risk of adverse events. There is increasing demand for the training of endoscopists in these procedures, but limited guidelines exist concerning procedural competency. The aim of this study was to assess the learning curves for LGI polypectomy, colorectal endoscopic mucosal resection (EMR) and colorectal endoscopic submucosal dissection (ESD). METHOD A systematic review of electronic databases between 1946 and September 2019 was performed. Citations were included if they reported learning curve data. Outcome measures that defined the success of procedural competency were also recorded. RESULTS A total of 34 out of 598 studies met the inclusion criteria of which 28 were related to ESD, three to polypectomy and three to EMR. Outcome measures for polypectomy competency (en bloc resection, delayed bleeding and independent polypectomy rate) were achieved after completion of between 250 and 400 polypectomies and after 300 colonoscopies. EMR outcome measures, including complete resection and recurrence, were achieved variably between 50 and 300 procedures. Outcome measures for ESD included efficiency (resection rates and procedural speed) and safety (adverse events). En bloc resection rates of over 80% and R0 resection rates of over 70% were achieved at 20-40 cases and procedural speed increased after 30 ESD cases. Competency in safety metrics was variably achieved at 20-200 cases. CONCLUSION There is a paucity of data on learning curves in LGI polypectomy, EMR and ESD. Despite limited evidence, we have identified relevant outcome measures and threshold numbers for the most common LGI polyp resection techniques for potential inclusion in training programmes/credentialing guidelines.

Abstract
Coronary artery disease (CAD) patients might have concomitant mesenteric artery stenosis (MAS). Identification of risk factors predicting mesenteric artery involvement might guide screening high risk individuals. A dilemma of intervention in radiologically severe MAS exists. This prospective study included CAD patients undergoing a coronary angiogram. A concomitant mesenteric angiogram was performed to diagnose MAS. Clinically relevant MAS (CR-MAS) was defined as i) presence of classical mesenteric angina with any degree of MAS or ii) severe stenosis (> 70%) involving two or more vessels. Risk factors for CR-MAS were studied and followed up prospectively. One hundred and three patients were included in the study. Left anterior descending artery was the most common involved coronary artery and was affected in 73% (n = 76). Mesenteric angiogram revealed 42.7% (n = 44) to have MAS. CR-MAS was present in 21 patients (20.4%). Involvement of celiac axis, superior mesenteric artery and inferior mesenteric artery was 22, 39 and 15 respectively. Multivariate analysis showed mesenteric angina (p < 0.01), diabetes mellitus (p < 0.01) and peripheral artery disease (p < 0.01) to be independent predictors of CR-MAS. At a median follow-up of 36 months (range 29-48 months), there was no acute mesenteric ischemia. In patients with CR-MAS, 16 (76.2%) had symptomatic improvement and 5 (23.8%) had stable symptoms. Three patients underwent angioplasty of superior mesenteric artery for persistent symptoms. Chronic CAD patients had a high prevalence of MAS. Mesenteric angina, diabetes mellitus and peripheral artery disease are independent predictors of CR-MAS. Intervention for MAS should be dictated by symptoms and not radiological severity. Lifestyle modification and medication for atherosclerotic ischemic heart disease probably prevents acute mesenteric ischemia in CAD patients.

Abstract
AIM Lynch syndrome (LS) accounts for 2-4% of all colorectal cancer (CRC) cases, and is associated with an increased risk of developing metachronous colorectal cancer (mCRC). The role of extended colectomy in LS CRC is controversial. There are limited studies comparing the risk of mCRC following segmental colectomy and extended colectomy. The objective of this systematic review is to evaluate the risk of developing mCRC following segmental and extended colectomy for LS CRC and endoscopic compliance. METHOD A systematic review of major databases was performed using predefined terms. All original articles published in English comparing the risk of mCRC in LS patients after segmental and extended colectomy from 1950 to January 2016 were included. RESULTS The search retrieved 324 studies. Six studies involving 871 patients met the inclusion criteria. Of these, 705 (80.9%) underwent segmental colectomy and 166 (19.1%) extended colectomy. Average follow-up was 91.2 months. The mCRC rate was 22.8% and 6% in the segmental and extended colectomy groups, respectively. The segmental group were over four times more likely to develop mCRC (OR 4.02, 95% CI: 2.01-8.04, P < 0.0001). mCRC occurred in patients after segmental colectomy despite 1-2-yearly postoperative endoscopic surveillance. CONCLUSION This result suggests that extended colectomy reduces the risk of mCRC by over four-fold compared with segmental colectomy. mCRC occurred in the segmental group despite postoperative endoscopic surveillance. This needs to be borne in mind when deciding on the appropriate surgical management of LS patients with CRC. We recommend that extended colectomy should be considered for patients with confirmed LS CRC.

Abstract
Background and study aims Colonic polypectomy is acknowledged to be a technically challenging part of colonoscopy. Training in polypectomy is recognized to be often inconsistent. This study aimed to ascertain worldwide practice in polypectomy training. Patients and methods An electronic survey was distributed to endoscopic trainees and trainers in 19 countries asking about their experiences of receiving and delivering training. Participants were also asked about whether formal polypectomy training guidance existed in their country. Results Data were obtained from 610 colonoscopists. Of these responses, 348 (57.0 %) were from trainers and 262 (43.0 %) from trainees; 6.6 % of trainers assessed competency once per year or less often. Just over half (53.1 %) of trainees had ever had their polypectomy technique formally assessed by any trainer. Approximately half the trainees surveyed (51.1 %) stated that the principles of polypectomy had only ever been taught to them intermittently. Of those trainees with the most colonoscopy experience, who had performed over 500 procedures, 48.2 % had had training on removing large polyps of over 10 mm; 46.2 % (121 respondents) of trainees surveyed held no record of the polypectomies they had performed. Only four of the 19 countries surveyed had specific guidelines on polypectomy training. Conclusions A significant number of competent colonoscopists have never been taught how to perform polypectomy. Training guidelines worldwide generally give little direction as to how trainees should acquire polypectomy skills. The learning curve for polypectomy needs to be defined to provide reliable guidance on how to train colonoscopists in this skill.

Abstract
The implementation of new treatment strategies based on current recommendations has enabled a greater number of patients with rheumatoid arthritis (RA) to achieve remission. However, there are no definite predictors of sustained remission. Moreover, the absence of clear consensus on the time of withdrawal or reduction of treatment further adds to the treatment burden. This pilot study was intended to evaluate the prognostic potential of various RA-related parameters. All the enrolled subjects (n=124) were clinically evaluated on the basis of various parameters including age, gender, duration of illness before the initiation of disease-modifying anti-rheumatic drugs, tender and swollen joints (28 joints), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), hemoglobin percentage, lymphocyte count, total white-blood cell counts, and neutrophil to lymphocyte ratio (NLR). Student's t-test and discriminant function analysis were performed. The specificity of all parameters and their best possible cut-off to predict relapse were calculated using the receiver operating characteristic (ROC) analysis. A significant difference in terms of pain perception, NLR, tendency to have a significant tender joint count and absolute lymphocyte counts was identified between the patients in sustained remission and those in relapse. The ROC analysis indicated that NLR was consistent in predicting remission. CRP, ESR, and/or disease activity score may not be very effective in differentiating patients with sustainable remission/low disease activity. NLR along with patient's perception of pain may assist in predicting sustained remission.

Abstract
The study of changes in ground water quality on the east coast of chennai due to the December 26, 2004 tsunami and other subsequent disturbances is a matter of great concern. The post-Tsunami has caused considerable plant, animal, material and ecological changes in the entire stretch of chennai coastal area. Being very close to sea and frequently subjected to coastal erosion, water quality has been a concern in this coastal strip, and especially after the recent tsunami this strip seems to be more vulnerable. In the present investigation, ten ground water samples were collected from various parts of south chennai coastal area. Physico-chemical parameters such as pH, temperature, Biochemical oxygen demand (BOD), Dissolved oxygen (DO), total solids; turbidity and fecal coliform were analyzed. The overall Water quality index (WQI) values for all the samples were found to be in the range of 68.81-74.38 which reveals a fact that the quality of all the samples is only medium to good and could be used for drinking and other domestic uses only after proper treatment. The long term adverse impacts of tsunami on ground water quality of coastal areas and the relationships that exist and among various parameters are carefully analyzed. Local residents and corporation authorities have been made aware of the quality of their drinking water and the methods to conserve the water bodies.

Abstract
The gross karyotype of the uraeotyphlid caecilian Uraeotyphlus gansi is described as comprising 2n = 42 and fundamental number = 58. These are the first karyotype data for any species of malabaricus-group Uraeotyphlus, and the diploid number is the same as those ichthyophiids thus far studied and differs from the oxyurus-group Uraeotyphlus (2n = 36). These data support the recognition of two species groups within Uraeotyphlus, the monophyly of the oxyurus group, and the understanding that the ancestral diatriatan was more ichthyophiid- than uraeotyphlid-like.

Abstract
This paper highlights the antagonism effect of Penicillium isolates, which were screened against the test organisms such as Staphylococcus aureus, E. coli and Penicillium sp. Penicillium notatum and Penicillium chrysogenum isolates were used for penicillin biosynthesis. The antibacterial activities of fermented crude penicillin extract were assayed by disc diffusion method. Maximum antibacterial activity was observed in Gram positive organisms (Staphylococcus aureus) when compared with Gram negative organisms. The isolated Penicillium chrysogenum can be used for large-scale penicillin antibiotic production.

Abstract
A simple and inexpensive absorption technique for determination of calcium ion in urine samples is developed, comprising a light emitting diode (650 nm) as the light source and photodiode as the detector with AT89C51RD2 microcontroller. The design of the system and details of interface, calibration, and procedure of operation are explained in this paper. Software is developed to monitor sample processing and to display the results in liquid crystal display screen. With 15 microl sample volume, a linear output is obtained in the range of 2.5-7.5 mM calcium with a detection limit of 0.06 mM. Interferences from other cations such as monovalent ion and divalent ion are investigated in the expected range, which are normally present in clinical samples, and absorption changes over the pH range of 3-12 are also determined. This system has been demonstrated successfully for the successive assay of calcium in urine samples, with the results comparing well to those achieved and in good agreement with values obtained with the current clinical spectrophotometric method at 95% of confidence level.

Abstract
Subcellular fractions (mitochondrial, cytosolic and microsomal) prepared from the tissues (hepatopancreas, muscle and gill) of freshwater prawns Macrobrachium malcolmsonii and Macrobrachium lamarrei lamarrei were scrutinized to investigate the presence of mixed function oxygenase (MFO) and conjugating enzymes (glutathione-S-transferase, GST). Cytochrome P450 (CYP) and other components (cytochrome b(5); NADPH-cytochrome c (CYP) reductase and NADH-cytochrome c-reductase activities) of the MFO system were predominantly present in the hepatic microsomal fraction of M. malcolmsonii and M. lamarrei lamarrei. The results are in agreement with the notion that monooxygenase system is mainly membrane bound in the endoplasmic reticulum, and that the hepatopancreas is the major metabolic tissue for production of biotransformation enzymes in crustaceans. Further, the prawns were exposed to two sublethal (0.9 ppt (parts per thousand) and 2.3 ppt) concentrations of oil effluent. At the end of 30th day, hydrocarbons and detoxifying enzymes were analysed in the hepatopancreas. The accumulations of hydrocarbon in the tissues gradually increased when exposed to sublethal concentrations of oil effluent and were associated with significantly enhanced levels of cytochrome P450 (180.6+/-6.34 pmol mg(-1) protein (P<0.05 versus control, 136.5+/-7.1 pmol mg(-1) protein) for 2.3 ppt and 305.6+/-8.5 pmol mg(-1) protein (P<0.001 versus control, 132.3+/-6.8 pmol mg(-1) protein] for 0.9 ppt of oil exposed M. malcolmsonii; 150+/-6.5 pmol mg(-1 )protein (P<0.01 versus control, 84.6+/-5.2 pmol mg(-1) protein) for 2.3 ppt and 175+/-5.5 pmol mg(-1) protein (P<0.01 versus control, 87.6+/-5.4 pmol mg(-1) protein) for 0.9 ppt of oil exposed M. lamarrei lamarrei), NADPH cytochrome c-reductase activity (14.7+/-0.6 nmol min(-1 )mg(-1) protein (P<0.05 versus control, 6.8+/-0.55 nmol min(-1 )mg(-1) protein) for 2.3 ppt and 12.1+/-0.45 nmol min(-1 )mg(-1) protein (P<0.01 versus control, 6.9+/-0.42 nmol min(-1 )mg(-1) protein) for 0.9 ppt of oil exposed M. malcolmsonii; 12.5+/-0.31 nmol min(-1 )mg(-1) protein (P<0.001 versus control, 4.6+/-0.45 nmol min(-1 )mg(-1) protein) for 2.3 ppt and 9.6+/-0.32 nmol min(-1 )mg(-1) protein (P<0.01 versus control, 4.9+/-0.41 nmol min(-1 )mg(-1) protein) for 0.9 ppt of oil exposed M. lamarrei lamarrei) and cytochrome b(5 )(124.8+/-3.73 pmol mg(-1) protein (P<0.01 versus control, 76.8+/-4.2 pmol mg(-1) protein) for 2.3 ppt and 115.3+/-3.86 pmol mg(-1) protein (P<0.01 versus control, 76.4+/-4.25 pmol mg(-1 )protein) for 0.9 ppt of oil exposed M. malcolmsonii and 110+/-3.11 pmol mg(-1) protein (P<0.01 versus control, 63.7+/-3.24 pmol mg(-1 )protein) for 2.3 ppt and 95.3+/-2.63 pmol mg(-1) protein (P<0.01 versus control, 61.4+/-2.82 pmol mg(-1) protein) for 0.9 ppt of oil exposed M. lamarrei lamarrei). The enhanced levels of biotransformation enzymes in oil-exposed prawns demonstrate a well-established detoxifying mechanism in crustaceans, and the response offers the possibility of use as a biomarker for the early detection of oil pollution.

Abstract
A total of 30 leprosy patients (controls n = 16; topical phenytoin n = 14) with trophic ulcers on the feet were investigated to ascertain the efficacy of topical phenytoin powder in the healing of ulcers. The ulcers in the two groups were matched for initial size. Healing patterns were assessed by determining changes in depth and planar (surface) dimensions at weekly intervals over a three week study period. Results indicate that while immobilization of the ulcer site is effective in promoting ulcer healing, additional use of topical phenytoin accelerates the healing process. There may however be non-responders to topical phenytoin.
