Image dataset of Pune city historical places for degradation detection, classification, and restoration.

Historical and ancient murals hold clues to life in the past. This depicts the culture, worship styles, and social life of the community. This fascinates researchers and scholars who study historical bindings to showcase the modern world. Over time, most of these historical monuments have not been preserved in their original state. Most of these are affected due to natural climatic conditions, civil wars, and natural disasters. It remains clueless and imaginary about the size, shape, and color of the distorted historical monuments. This results in limitations for historical studies, archeological research, and geographical surveys. In this paper, we have studied the historical places around Pune city. Identified the locations where the monuments have been distorted and reconstructed recently. The construction age, type, color, shape, and size of the monuments are the major parameters of our study. Based on these criteria, we have captured images of these objects through different angles and camera lens. We have collected and categorized these images into folders with the names of historical places. This image dataset contains both captured and augmented images with distinct angles, scales, and directions. It also includes images captured in the daytime and evening with artificial lighting. This image dataset contains a variety of distinct image patterns that are useful as input to train computer-based supervised learning. The machine learning and deep learning algorithms perform efficiently if the input image dataset is large and distinct. Based on the predictive results generated by the machine learning and deep learning models, it is possible to virtually recreate the original monument. This would add a key value to historical research and studies.

Polymorphisms of MDR1, CYP2C19 and P2Y12 genes in Indian population: effects on clopidogrel response.

AIMS/OBJECTIVE: Influence of genetic variations on the response of clopidogrel, an antiplatelet drug is implicated. In the present study, the prevalence of single nucleotide polymorphisms of MDR1 (C3435T), CYP2C19 [CYP2C19*2 CYP2C19*3, CYP2C19*17] and P2Y12 (i-T744C) in Indian population and their effects on clopidogrel response was analyzed. METHODS AND RESULTS: To analyze the prevalence of polymorphisms, 102 healthy individuals were recruited. Clopidogrel response was assessed by ADP induced platelet aggregation in clopidogrel naïve acute myocardial infarction (AMI) patients (n = 26) screened from 100 AMI cases, before loading dose of 300 mg, at 24 h before next dose and 6 days after on 75 mg per day and platelet aggregation inhibition (PAI) was calculated between these time intervals. Genotyping was carried out by PCR-based restriction enzyme digestion method for C3435T of MDR1 and i-T744C of P2Y12, by multiplex PCR for CYP2C19*2 (G681A) and CYP2C19*3 (G636A) and by nested PCR for CYP2C19*17 (C806T). The effect of the above mentioned genetic variations on PAI was analyzed. Variant allele of CYP2C19*3 was not observed while the prevalence of 3435T of MDR1 (0.524), CYP2C19*2 (681A, 0.352); i-744C of P2Y12 (0.088), as well as wild type allele CYP2C19*17 (C806, 0.897) associated with decrease clopidogrel response were observed. Trend toward poor response to clopidogrel was observed at 24 h with the variant genotypes of CYP2C19*2 and i-T744C of P2Y12 as compared to wild type. CONCLUSION: The present study did show a trend toward impaired response of clopidogrel to inhibit platelet aggregation with variant genotypes of CYP2C19*2 and iT744C of P2Y12 compared to respective wild type genotype at 24 h.

Bhawsar-karandikar stent: an aid to vestibuloplasty.

The loss of teeth and their replacement by artificial denture is associated with many problems. Pre-prosthetic surgical procedures are performed to provide a better anatomic environment and to create proper supporting structures for construction of dentures. Whenever inadequate vestibular depth is present in edentulous mouth, deepening of vestibule is considered to increase the retention and stability of denture. Deepening of vestibule without any addition of the bone is termed as vestibuloplasty. This article describes the ease and convenience of vestibuloplasty followed by the use of Bhawsar-Karandikar stent to maintain the soft tissue modifications. The study yielded promising results and patient acceptance.

Study of C-reactive protein and myocardial infarction in the Indian population.

To analyse the association of high sensitivity C-reactive (hsCRP) protein levels and -717A/G single nucleotide polymorphism of CRP with acute myocardial infarction (AMI) in the Indian population. Study population included 100 MI cases wherein 32 patients had experienced previous MI (MI-Group-1), 68 MI cases were recruited at presentation (MI-Group-2) and equal number of age and gender matched healthy individuals. hsCRP levels were determined by ELISA and genotyping of -717A/G was carried out by polymerase chain reaction-based restriction digestion method. The -717A/G genotypes did not influence hsCRP level and their distribution did not differ between groups. However, in the present study hsCRP demonstrated significant correlation with BMI in controls of both the genders and with triglycerides in females of AMI at presentation who otherwise are with low risk profile. Identifying traditional risk factors associated with inflammation may help in controlling the acute event.

Prevalence of VKORC1 and CYP2C9 gene polymorphisms in Indian population and its effect on warfarin response.

OBJECTIVES: The clinical effectiveness of Warfarin is established. Patients require different warfarin dosages to achieve the target therapeutic anticoagulation. The variability of Warfarin dosage is largely genetically determined, and it can be partly explained by the C1173T and G-1639A polymorphisms of vitamin K epoxide reductase complex subunit 1 (VKORC1) which is its target and *2 and *3 allele of Cytochrome P-450 (CYP) 2C9 [CYP2C9] enzyme which metabolizes to its inactive form. Aim of the present study was to determine the prevalence of these variant alleles known to influence the warfarin dose and correlate genotypes with the average INR as well as mean dose of Warfarin required to maintain INR, in the Indian population. METHODS: Study population included 100 healthy individuals and 83 patients operated for Aortic or Mitral Valve replacement and prescribed warfarin thereafter. Of these 83 patients records of INR for the period of six months and mean maintenance dose (stable therapeutic dose) of warfarin required to maintain INR were available for 26 patients. For the remaining patients, apart from their demographic data only maintenance dose was available. Genotyping of above mentioned polymorphisms was carried out by using PCR-based restriction digestion method. RESULTS: Although less as compared to wild type alleles, the variant alleles of CYP2C9*2 and *3 as well as of VKORC1 polymorphisms (C1173T and G-1639A) were observed in our study population. Mean maintenance dose (mg/day) of Warfarin was in the decreasing order of patients as compared to the wild type genotypes for all above mentioned polymorphisms. The decrease in the dose was in the order of heterozygotes for CYP2C9*2 to CYP2C9*3 to C1173T and G-1639A of VKORC1 (P<0.001). There was significant correlation (r=0.51, P<0.001) observed between the dose estimated by pharmacogenetic algorithm of Sconce et al (2005) and actual stable therapeutic dose. INR was high for mutant variants (3.8 to 4) after first dose suggesting that they require decreased mean daily dose of Warfarin. CONCLUSION: In the present study the effect of CYP2C9*2, *3, and VKORC1 (C1173T and G-1639A) genotypes on warfarin dose was observed. However, the genotyping has not been incorporated into daily practice. Perhaps more practical approach would be for clinicians to take genotype information into consideration along with other factors when dosing warfarin.
