Published: November 2022

This work aims to figure out a way to accurately identify license plate numbers in photos taken by drones. This technology is used in practical applications like managing parking and traffic. The goal is to extract features from the images that are robust and invariant features using the phase congruency model. These proposed features can handle the challenges posed by drone images. After that, the work will take advantage of a fully connected neural network to tackle the difficulties of fixing precise bounding boxes regardless of orientations, shapes, and text sizes. The proposed work will be able to find the detected text for both license plate numbers and natural scene images which will lead to a better recognition stage. Both our drone dataset and the benchmark license plate dataset (Medialab) are used to assess the effectiveness of the study that has been done. To show that the suggested system can detect text of natural scenes in a wide variety of situations. Four benchmark datasets, namely SVT, MSRA-TD-500, ICDAR 2017 MLT, and Total-Text are used for the experimental results. We also describe trials that demonstrate robustness to varying height distances and angles. The code and data used in the study will be made available on GitHub.

Published: November 2022

Introduction and Aim: Obesity is becoming a worldwide problem and women were more likely to be obese than men in all regions of world. Obesity affects multiple systems of the body including respiratory system. This study aimed at comparing the respiratory functions before and after cycling in obese and non obese young women.

Materials and Methods: One hundred healthy female in the age groups of 18-25 years were considered. Fifty subjects were obese [BMI>25 kg/m2] and 50 were age matched non obese [BMI=18 to 22.9 kg/m2]. Anthropometric measurements weight, height, waist circumference, hip circumference were measured. BMI and waist hip ratio were calculated. Spirometric parameters like FVC (Functional Vital Capacity), FEV1 (Forced expiratory volume 1 second), FEV1/FVC ratio were assessed before cycling. Cycling (a graded submaximal exercise) was performed using YMCA cycling protocol. Spirometric parameters were assessed within 5 minutes from termination of cycling. Data collected were statistically analyzed using paired ‘t’ test.

Results: Before cycling and after cycling values of FVC, FEV1/FVC in obese young women were lower (p<0.0001) compared to non obese young women but their values were within normal range of % prediction. On comparing the FVC, FEV1, FEV1/FVC values from before to after cycling there was statistically significant reduction in both the groups. On comparison of reduction in spirometric values from before to after cycling, among obese and non obese young women, it was not statistically significant.

Conclusion: Both in before and after cycling the obese young women had reduced pulmonary function test compared to non obese young women but values within the normal percentage of prediction.

As Sars CoV 2 infection was accountable for present global pandemic, many novel therapies and traditional medicines have been implied by various countries for the management and prevention of the spread. From the beginning, Corona virus mutation is also progressing with different variants. Delta variant was the most dreadful and contagious one, among the variants, which hospitalized more people. Now, Omicron is the new variant of concern announced by WHO in November 2021 which makes the disease more transmissible. In India, as the cases started rising from January 2022 by this new variant, various measures had been taken for the management of the disease. Traditional Siddha formulations were given for cases reported with positive Covid 19 infection, in home setting, at Chennai and the reports were shared here. Despite, genome sequencing is the precise diagnostic tool for variants detection, the cases reported here were in close possibility of omicron and mixed variants. Maha vasantha kusumakaram tablet a shastric higher order metallic preparation was proven to be effective with herbal preparations Thippili rasayanam, adathodai kudineer and Amukkara choornam. The patients recovered in a short span of time and the repeat Real time polymerase chain reaction (RTPCR) tested negative within 10 days. This was highly encouraging that Siddha medicines were proven to be effective in different variants of mutated Covid virus with no adverse effects and the medicines proved to be safe and effective by post- test of liver and renal parameters.

Introduction and Aim: Citrus fruits are rich in polyphenolic compounds. The conventional medical system has utilized the fruit’s entire composition including the peel for its diverse biological functions. With this, the study aimed to assess and compare the phytochemical, in-vitro antioxidant analysis as well as polyphenol and flavonoid content of Citrus maxima juice, aqueous and ethanolic extracts of its pulp and peel.

Materials and Methods: Qualitative phytochemical screening, total phenolic content and total flavonoid content and different in-vitro antioxidant assays like total antioxidant capacity (TAC), Ferric reducing antioxidant power assay (FRAP), 2,2-diphenyl-2-picryl hydrazyl (DPPH) radical scavenging assay were carried out to evaluate the in-vitro antioxidant potential in the juice, aqueous and ethanolic extract of pulp and peel of C. maxima. Gas chromatography–Mass spectrometry (GC–MS) analysis was performed in the peel ethanolic extract to identify the compounds present.

Results: Preliminary phytochemical analysis revealed the presence of triterpenoids and steroids, glycosides, alkaloids, flavonoids, carbohydrates and vitamin C in all the C. maxima crude extracts. Tannins were present only in pulp of ethanol extract and in both aqueous and ethanol extracts of peel. Resins were present in the juice and ethanol extract of pulp and peel. The total phenol and total flavonoid content was comparatively higher in ethanolic extracts of peel. All the extracts showed dose-dependent free radical scavenging activity. The reducing potential of the C.maxima extractives increased with the increase in its concentration. GC-MS analysis of ethanolic peel extract identified key constituents with pharmacological effects. The ethanolic peel extract showed good antioxidant activity and free radical scavenging activity when compared to other extracts.

Conclusion: The results indicated that ethanolic peel extract of Citrus maxima revealed the highest presence of polyphenolic compounds, which are secondary plant metabolites with potential antioxidant activity.

Introduction and Aim: Cardiovascular diseases are the leading cause of death worldwide. The prevalence of cardiovascular disease in India is continuously on the rise owing to the socioeconomic changes the country is undergoing. In order to minimise the mortality due to cardiovascular disease, early detection and control of modifiable risk factors is of utmost importance. We evaluated the correlation of vitamin D deficiency, one such possible modifiable risk factor, and the severity of CAD in patients at a hospital in Southern Karnataka. Unfortunately, relevant data regarding vitamin D deficiency in coronary artery disease pertaining to the Indian subcontinent is scarce. Thus, the results of our study can provide further evidence for the potential therapeutic benefit of Vitamin D in patients with cardiovascular risk factors, which in the long run can significantly reduce the morbidity and mortality of CAD.

Materials and Methods: A case-control study with 142 subjects was conducted in Kasturba Hospital. Based on coronary angiogram findings, cases were categorised as having single, double, triple or multi vessel disease. Vitamin D level was quantified into 3 categories: normal (>30ng/ml), insufficient (20-30ng/ml) and deficient (<20ng/ml).

Results: Vitamin D deficiency was statistically significantly and inversely related to the number of vessels involved (multi vessel disease-83.3%, triple vessel disease-80%, double vessel disease-28.6% and single vessel disease-21.7%). The relationship between vitamin D levels and syntax scoring showed a negative correlation (-0.339). Multiple linear regression analysis showed that the severity of CAD was correlated to diabetes and vitamin D deficiency with p-value of 0.014.

Conclusion: Both our results and those of previous studies suggest that vitamin D could have a potential therapeutic effect in CAD.

Published: November 2022

Introduction and Aim: Breast cancer is the commonest malignancy in women. Most women do not die of the primary tumor but from metastasis and local invasion. Augmented motility of cancer cells corroborates with greater metastatic potential, that is brought about by actin cytoskeleton. Fascin, a cytoplasmic F-actin-bundling protein that cross-links actin filaments and its overexpression is strongly associated with metastatic progression and poor prognosis. The present study aims to determine the fascin protein expression by immunohistochemistry in invasive breast carcinoma and to correlate the same with the existing prognostic factors.

Methods: Immunohistochemical expression of fascin in 100 cases of invasive mammary carcinoma was studied. Data collected was scored based on intensity and statistically analyzed using GNU-PSPP version 0.10 software. To determine significant clinico-pathological differences between fascin expression in positive and negative tumors, Pearson Chi-square test was used.

Results: It was noted that 22 of the 100 cases were positive with a score of 3 or more. A significant association of nodal status with fascin (p value <0.05) was noted. Higher proportion of fascin positive tumors were node negative. There was an inverse correlation between ER/PR/HER2 status and fascin positivity. The corresponding p values for ER, PR and HER2 with fascin were <0.05. On the contrary 12(57.15%) of the 21 triple negative cases were fascin positive. The p value was <0.001 indicating a significant correlation between molecular subtypes and fascin expression. A more of the fascin positive tumors fell in the triple negative category.

Conclusion: Higher proportion of fascin positive cases in the node negative category, an inverse correlation between fascin expression and individual ER/PR, HER2 expression and larger number of fascin positive cases in the triple negative category. These findings point an association of fascin with aggressive breast carcinomas.

Published: November 2022

Introduction and Aim: Homocysteine (Hcy) is considered as an independent risk factor for coronary artery disease (CAD). Hyperhomocysteinemia (HHcy) may be caused due to the deficiency of vitamin B12, folic acid (FA), and pyridoxine (B6) or due to genetic polymorphism in methylenetetrahydrofolate reductase (MTHFR). A pilot study was undertaken to investigate Hcy levels and its association with lipid profile in patients with CAD.

Methods: Lipid profile values were obtained from laboratory reports and the Hcy levels were estimated by enzymatic cycling assay using the commercial kits in autoanalyzer in subjects with CAD (n=12).

Results: Hcy (14.58 ± 8.32 µmol/L), LDL (134.75 ± 45.02 mg/dl) and non-HDL (150.25 ± 56.89 mg/dl) levels were found to be elevated in patients with CAD.

Conclusion: Dyslipidemia was associated with variable Hcy levels. Few patients with HHcy showed concurrent upsurge in LDL and non-HDL levels.

Published: November 2022

Introduction and Aim: Large body of evidence suggests that oxidative stress has a crucial role to play in diabetes and its related complications. In the present research we have tried to determine potential risk factors for oxidative stress in type 2 diabetes by conducting a cross-sectional study.

Materials and Methods: We studied 238 patients with or without complications of diabetes, aged 40-75 years. Blood samples were analysed for fasting plasma glucose, glycated haemoglobin, malondialdehyde, total cholesterol, triglyceride, LDL-cholesterol and HDL-cholesterol. Each patient’s waist circumference, BMI, blood pressure was measured.

Results: Participants mean age was 57.5 ± 8.9 years. Logistic regression analysis identified glycated haemoglobin (95% CI: 1.02-1.92; p=0.04), hypertension (95% CI: 0.99-4.08; p=0.05) and LDL-cholesterol (95% CI: 1.12-5.87; p=0.03) as independent risk factors for oxidative stress. Other contributors were age and presence of complications like nephropathy, retinopathy, peripheral neuropathy and macrovascular disease in diabetes.

Conclusion: Our data demonstrate that ‘ABCs of diabetes’ namely HbA1c, blood pressure and LDL-cholesterol are independent risk factors for oxidative stress. Oxidative stress aggravates with age and presence of complications. It appears important to achieve a good ABC goal to bring down oxidative stress in diabetes.
