Abstract
AIMS This multicentric retrospective study reports long-term clinical outcomes of non-metastatic grade group 5 prostate cancers treated with external beam radiotherapy (EBRT) alone with long-term androgen deprivation therapy (ADT). MATERIALS AND METHODS Patients treated across 19 institutions were studied. The key endpoints that were evaluated were 5-year biochemical recurrence-free survival (bRFS), metastases-free survival (MFS), overall survival, together with EBRT-related acute and late toxicities. The impact of various prognostic factors on the studied endpoints was analysed using univariate and multivariate analyses. RESULTS Among the 462 patients, 88% (405) had Gleason 9 disease and 31% (142) had primary Gleason pattern 5. A prostate-specific membrane antigen positron emission tomography-computed tomography scan was used for staging in 33% (153), 80% (371) were staged as T3/T4 and 30% (142) with pelvic nodal disease. The median ADT duration was 24 months; 66% received hypofractionated EBRT and 71.4% (330) received pelvic nodal irradiation. With a median follow-up of 56 months, the 5-year bRFS, MFS and overall survival were 73.1%, 77.4% and 90.5%, respectively. Primary Gleason pattern 5 was associated with worse bRFS, MFS and overall survival with hazard ratios of 0.51 (95% confidence interval 0.35 to 0.73, P < 0.001), 0.64 (95% confidence interval 0.43 to 0.96, P = 0.031) and 0.52 (95% confidence interval 0.28 to 0.97, P = 0.040), respectively, whereas pelvic nodal disease was associated with worse bRFS (hazard ratio 0.67, 95% confidence interval 0.46 to 0.98, P = 0.039) and MFS (hazard ratio 0.56, 95% confidence interval 0.37 to 0.85, P = 0.006). The acute and late radiation-related toxicities were low overall and pelvic nodal irradiation was associated with higher toxicities. CONCLUSION Contemporary EBRT and long-term ADT led to excellent 5-year clinical outcomes and low rates of toxicity in this cohort of non-metastatic grade group 5 prostate cancers. Primary Gleason pattern 5 and pelvic node disease portends inferior clinical outcomes.

Abstract
INTRODUCTION: The use of natural resources as medicines for cancer therapies has been described throughout history in the form of traditional medicines. However, many resources are still unidentified for their potent biological activities. Clerodendrum viscosum is a hill glory bower reported as a remedy against oxidative stress, skin diseases, and intestinal infections. MATERIALS AND METHODS: We have collected the C. viscosum leaves and used for the preparation of 70% methanolic extract (CVLME). Then, CVLME has been confirmed for anticancer properties on various cancer cell lines by evaluating cytotoxicity, cell cycle analysis, induction of ROS and apoptosis, and nuclear fragmentation. Further, the phytochemical analysis of CVLME was evaluated through high-performance liquid chromatography. RESULTS: Cell proliferation assay revealed the selective cytotoxicity of CVLME against breast cancer cell line (MCF-7). The FACS-based cell cycle analysis showed increased subG1 (apoptosis) population dose dependently. Further, the apoptosis-inducing effect of CVLME was confirmed by annexin staining. Flow cytometry and confocal microscopy revealed the selective ROS generation upon CVLME treatment. The confocal-based morphological study also revealed condensed and fragmented nuclear structure in CVLME-treated MCF-7 cells. Phytochemical investigations further indicated the presence of tannic acid, catechin, rutin, and reserpine which might be the reason for the anticancer activity of CVLME. CONCLUSION: The above-combined results revealed the anticancer effect of CVLME, which may be due to the selective induction of ROS in breast carcinoma.

Abstract
Excess iron causes oxidative damage of biomolecules, leading to tissue injury primarily liver failure. In this study, we explored the remediating effects of Morus alba L. (MAME) on iron-overload-induced oxidative stress and liver injury in mice. The In vitro study revealed the antioxidant and free radical scavenging properties of MAME. Intraperitoneal injection of iron-dextran was administered in Swiss albino mice to induce iron-overload condition and the mice were further treated with MAME. MAME treatment significantly decreased liver iron, serum ferritin level, oxidative stress, and restored serum parameters and liver antioxidants. Moreover, biochemical and histopathological analyses confirmed the alleviated liver damage and fibrosis upon MAME treatment. The protective effect of MAME against iron-overload-induced apoptosis was confirmed by upregulation of protein levels of Bax, Caspase-3, and PARP. The treatment also affected the expression of MAPKs (ERK, JNK, and p38). GC-MS analysis revealed the presence of various bioactive phytochemicals in MAME that may be responsible for ameliorating effects of excess iron. Thus MAME can be envisaged as an effective iron chelator in the treatment of iron-overload-induced liver injury and fibrosis.

Abstract
BACKGROUND Farsetia hamiltonii Royle, also known as Hiran Chabba grows in desert regions. It is widely used as folk medicine to treat joint pains, diarrhea and diabetes. However, its antioxidant and iron chelation abilities both in vitro and in vivo have not yet been investigated. METHODS The 70% methanolic extract of F. hamiltonii (FHME) was investigated for its free radical scavenging and iron chelation potential, in vitro. An iron-overload situation was established by intraperitoneal injection of iron-dextran in Swiss albino mice, followed by oral administration of FHME. Liver damage and serum parameters due to iron-overload were measured biochemically and histopathologically to test iron-overload remediation and hepatoprotective potential of FHME. Phytochemical analyses were performed to determine its probable bioactive components. RESULTS FHME showed promising antioxidant activity, scavenged various reactive oxygen and nitrogen species and chelated iron in vitro. FHME reduced liver iron, serum ferritin, normalized serum parameters, reduced oxidative stress in liver, serum and improved liver antioxidant status in ironoverloaded mice. It also alleviated liver damage and fibrosis as evident from biochemical parameters and morphological analysis of liver sections. The phytochemical analyses of FHME reflected the presence of alkaloids, phenols, flavonoids and tannins. HPLC analysis indicated presence of tannic acid, quercetin, methyl gallate, catechin, reserpine, ascorbic acid and gallic acid. CONCLUSION Based on the experimental outcome, FHME, an ethnologically important plant can be envisaged as excellent antioxidant and iron chelator drug capable of remediating iron-overload induced hepatotoxicity and the bioactive compounds present in FHME might be responsible for its efficacy.

Abstract
BACKGROUND With 9.6 million deaths in 2018, cancer remains the second leading cause of death worldwide. Breast cancer is the most deadly type of cancer among females, with 55.2% of crude incidence rate and 16.6% of crude mortality rate. PURPOSE The present study was aimed to investigate the anti-breast cancer potential of natural dietary flavonoid, apigenin isolated from Clerodendrum viscosum leaves. METHODS Apigenin was evaluated for in-depth anticancer activity in MCF-7 cells using cell viability assay, cell cycle analysis, Annexin-V-FLUOS staining, ROS induction, morphological analysis, and western blot analysis. RESULTS Apigenin showed selective cytotoxicity on MCF-7 cells with an IC50-56.72 ± 2.35 µM, while negligible cytotoxicity was observed on WI-38 cells. Further, the flow cytometer-based analysis showed that apigenin halted MCF-7 cells in the G2/M phase arrest followed by dose-dependent apoptosis. Moreover, the FACS and confocal microscopy results confirmed the elevation of intracellular ROS and nuclear fragmentation in apigenin-treated MCF-7 cells. Western blots showed up-regulation of cell cycle regulatory proteins, increased p53 expression, Bax/Bcl-2 ratio, activation of caspases, and cleavage of PARP. Finally, apigenin treatment in the presence of Pifithrin-µ showed decreased apoptotic population and it was further confirmed through western blotting study. The results revealed the vital role of p53 in apigenin-induced apoptosis in MCF-7 cells. CONCLUSIONS In the present findings, treatment of apigenin-induced intracellular ROS in MCF-7 cells followed by induction of G2/M phase cell cycle arrest and further apoptosis through the regulation of p53 and caspase-cascade signaling pathway.

Abstract
Objectives Socio-economic inequalities may affect coronavirus disease 2019 (COVID-19) incidence. The goal of the research was to explore the association between deprivation of socio-economic status (SES) and spatial patterns of COVID-19 incidence in Chennai megacity for unfolding the disease epidemiology. Study design This is an ecological (or contextual) study for electoral wards (subcities) of Chennai megacity. Methods Using data of confirmed COVID-19 cases from May 15, 2020, to May 21, 2020, for 155 electoral wards obtained from the official website of the Chennai Municipal Corporation, we examined the incidence of COVID-19 using two count regression models, namely, Poisson regression (PR) and negative binomial regression (NBR). As explanatory factors, we considered area deprivation that represented the deprivation of SES. An index of multiple deprivations (IMD) was developed to measure the area deprivation using an advanced local statistic, geographically weighted principal component analysis. Based on the availability of appropriately scaled data, five domains (i.e., poor housing condition, low asset possession, poor availability of WaSH services, lack of household amenities and services, and gender disparity) were selected as components of the IMD in this study. Results The hot spot analysis revealed that area deprivation was significantly associated with higher incidences of COVID-19 in Chennai megacity. The high variations (adjusted R2: 72.2%) with the lower Bayesian Information Criteria (BIC) (124.34) and Akaike's Information Criteria (AIC) (112.12) for NBR compared with PR suggests that the NBR model better explains the relationship between area deprivation and COVID-19 incidences in Chennai megacity. NBR with two-sided tests and P <0.05 were considered statistically significant. The outcome of the PR and NBR models suggests that when all other variables were constant, according to NBR, the relative risk (RR) of COVID-19 incidences was 2.19 for the wards with high housing deprivation or, in other words, the wards with high housing deprivation having 119% higher probability (RR = e0.786 = 2.19, 95% confidence interval [CI] = 1.98 to 2.40), compared with areas with low deprivation. Similarly, in the wards with poor availability of WaSH services, chances of having COVID-19 incidence was 90% higher than in the wards with good WaSH services (RR = e0.642 = 1.90, 95% CI = 1.79 to 2.00). Spatial risks of COVID-19 were predominantly concentrated in the wards with higher levels of area deprivation, which were mostly located in the northeastern parts of Chennai megacity. Conclusions We formulated an area-based IMD, which was substantially related to COVID-19 incidences in Chennai megacity. This study highlights that the risks of COVID-19 tend to be higher in areas with low SES and that the northeastern part of Chennai megacity is predominantly high-risk areas. Our results can guide measures of COVID-19 control and prevention by considering spatial risks and area deprivation. COVID-19 cases was modelled using Poisson regression and negative binomial regression. An IMD was devised using geographically weighted principal component analysis. Area deprivation in Chennai has both positive and inverse associations with the COVID-19.

Abstract
BACKGROUND Breast cancer is the most leading cause of death, with 49.9% of crude incidence rate and 12.9% of crude mortality rate. Natural resources have been extensively used throughout history for better and safer treatment against various diseases. OBJECTIVES The present study was aimed to investigate the antioxidant and anticancer potential of a tropical lichen Dirinaria consimilis (DCME) and its phytochemical analysis. METHODS The DCME was preliminarily evaluated for ROS, and RNS scavenging potential. Furthermore, DCME was evaluated for in vitro anticancer activity through cell proliferation assay, cell cycle analysis, annexin V/PI staining, morphological analysis, and western blotting study. Finally, the HPLC and LC-MS analyses were done to identify probable bioactive compounds. RESULTS The in vitro antioxidant studies showed promising ROS, and RNS scavenging potential of DCME. Moreover, the in vitro antiproliferative study bared the cytotoxic nature of DCME towards MCF-7 (IC50 - 98.58 ± 6.82μg/mL) and non-toxic towards WI-38 (IC50 - 685.85 ± 19.51μg/mL). Furthermore, the flow-cytometric analysis revealed the increase in sub G1 population as well as early apoptotic populations dose-dependently. The results from confocal microscopy showed the DNA fragmentation in MCF-7 upon DCME treatment. Finally, the western blotting study revealed the induction of tumor suppressor protein, p53, which results in increasing the Bax/Bcl-2 ratio and activation of caspase-cascade pathways. CONCLUSION The activation of caspase-3, -8, -9 and PARP degradation led us to conclude that DCME induces apoptosis in MCF-7 through both intrinsic and extrinsic mechanisms. The LC-MS analysis showed the presence of various bioactive compounds.

Abstract
Tannic acid (TA), a water soluble natural polyphenol with 8 gallic acids groups, is abundantly present in various medicinal plants. Previously TA has been investigated for its antimicrobial and antifungal properties. Being a large polyphenol, TA chelates more than 1 metal. Hence TA has been explored for potent antioxidant activities against reactive oxygen species (ROS), reactive nitrogen species (RNS) and as iron chelator in vitro thereby mitigating iron-overload induced hepatotoxicity in vivo. Iron dextran was injected intraperitoneally in Swiss albino mice to induce iron-overload triggered hepatotoxicity, followed by oral administration of TA for remediation. After treatment, liver, spleen, and blood samples were processed from sacrificed animals. The liver iron, serum ferritin, serum markers, ROS, liver antioxidant status, and liver damage parameters were assessed, followed by histopathology and protein expression studies. Our results show that TA is a prominent ROS and RNS scavenger as well as iron chelator in vitro. It also reversed the ROS levels in vivo and restricted the liver damage parameters as compared to the standard drug, desirox. Moreover, this natural polyphenol exclusively ameliorates the histopathological and fibrotic changes in liver sections reducing the iron-overload, along with chelation of liver iron and normalization of serum ferritin. The protective role of TA against iron-overload induced apoptosis in liver was further supported by changed levels of caspase 3, PARP as well as Bax/BCl-2 ratio. Thus, TA can be envisaged as a better orally administrable iron chelator to reduce iron-overload induced hepatotoxicity through ROS regulation.

Abstract
Background: Free radicals such as reactive oxygen and nitrogen species, generated in the body, play an important role in the fulfillment of various physiological functions but their imbalance in the body lead to cellular injury and various clinical disorders such as cancer, neurodegenaration, and inflammation. Objective: The objective of this study is to fight this problem, natural antioxidant from plants can be considered as possible protective agents against various diseases such as cancer which might also modify the redox microenvironment to reduce the genetic instability. This study was designed to evaluate the antioxidant and antiproliferative potential of Clerodendrum viscosum fractions against various carcinomas. Materials and Methods: In this present study, 70% methanolic extract of C. viscosum leaves have been fractionated to obtain hexane, chloroform, ethyl acetate, butanol, and water fractions, which were tested for their antioxidant and anticancer properties. Results: It was observed that chloroform and ethyl acetate fractions showed good free radical scavenging properties as well as inhibited the proliferation of human lung cancer (A459), breast (MCF-7), and brain (U87) cells. Moreover, they arrested the cell cycle at G2/M phase of breast and brain cancer. These inhibitory effects were further confirmed by bromodeoxyuridine uptake imaging. Phytochemical investigations further indicate the presence of tannic acid, quercetin, ellagic caid, gallic acid, reserpine, and methyl gallate which might be the reason for these fractions’ antioxidant and antiproliferative activities. Conclusion: Clerodendrum viscosum leaf chloroform and Clerodendrum viscosum leaf ethyl acetate fractions from C. viscosum showed good reactive oxygen species and reactive nitrogen species scavenging potential. Both the fractions arrested cell cycle at G2/M phase in MCF-7 and U87 cells which lead to induce apoptosis. SUMMARY Crude extract of Clerodendrum viscosum leaves was fractionated using different solvents Among them, chloroform and ethyl acetate fractions exhibited excellent free radical scavenging properties The same fractions inhibited the proliferation of human lung cancer (A459), breast (MCF-7), and brain (U87) cells Chloroform and ethyl acetate fractions arrested the cell cycle at G2/M phase of breast and brain cancer Phytochemical investigations further indicate the presence of several bioactive principles present in them.

Abstract
Terminalia belerica Roxb. fruits have been previously reported against diabetes, ulcer, microbial problems and hepatotoxicity. The present study was aimed to investigate antioxidant and anticancer potential of sequentially fractionated hexane (TBHE), chloroform (TBCE), ethyl acetate (TBEE), butanol (TBBE) and water (TBWE) extracts from the 70% methanolic extract of T. belerica fruits. TBCE, TBEE, TBBE and TBWE showed excellent ROS (reactive oxygen species) and RNS (reactive nitrogen species) scavenging activities which was investigated using 11 different assays for various free radicals. Among 5 fractions, TBHE and TBCE remained nontoxic to any of the malignant cell lines including normal cells (WI-38). TBBE and TBWE inhibited the proliferation of breast (MCF-7), cervical (HeLa) and brain (U87) cancer cells by inducing G2/M arrest while TBEE caused apoptosis. However, these fractions did not inhibit the proliferation of lung (A549) and liver (HepG2) cancer cells. BrdU incorporation study also suggested the efficient anticancer potential of TBEE, TBBE and TBWE. Moreover, TBBE and TBWE treated MCF-7, HeLa and U87 cells showed upregulation of p53 and p21 proteins. Phytochemical analysis reflected the presence of adequate quantities of different phytochemicals. Moreover, HPLC analysis show peaks of purpurin, catechin, tannic acid, reserpine, ellagic acid, methyl gallate, aconitine and rutin in TBBE, TBWE and TBEE. Hence these polar extracts of T. belerica can be used to develop drug against different types of cancer.

Abstract
BACKGROUND Iron in the overloaded condition in liver promotes the overproduction of free radicals that lead to oxidative stress and ultimately hepatic damage. The present study was designed to evaluate the ameliorating potential from iron overloaded hepatotoxicity by the glycosidic fraction from Spondious pinnata bark (SPW1) along with its antioxidant property. METHODS The fraction was tested for its in vitro antioxidant, free radical scavenging property and iron chelation potential via standard biochemical assays. Iron overload condition was generated by the intraperitoneal administration of iron dextran in mice. The levels of serum enzymes, antioxidant enzymes in liver, markers of hepatic damage, liver iron, and ferritin content were measured in response to the oral treatment of SPW1. Histopathology of the liver sections was performed for visual confirmation of the amelioration potential of SPW1. RESULTS The fraction exhibited excellent in vitro antioxidant as well as free radical scavenging potential against both reactive oxygen species and reactive nitrogen species. Administration of SPW1 significantly normalized the disturbed levels of antioxidant enzymes, liver iron, lipid peroxidation, liver fibrosis, serum enzyme and ferritin better than standard desirox which were also supported by the morphological study of the liver sections. Phytochemical analysis as well as HPLC study, confirmed that the fraction mainly consisted of glycosidic phenolics and flavonoids that attributed to its biological activities. CONCLUSIONS The above results suggested that beneficial effects of SPW1 on iron overload induced hepatotoxicity that can be considered as a possible candidate against iron overload diseases.

Abstract
Mycotoxins contamination in both food and feed is inevitable. Mycotoxin toxicity in foodstuff can occur at very low concentrations necessitating early availability of sensitive and reliable methods for their detection. The present research thrust is towards the development of a user friendly biosensor for mycotoxin detection at both academic and industrial levels to replace conventional expensive chromatographic and ELISA techniques. This review critically analyzes the recent research trend towards the construction of immunosensor, aptasensor, enzymatic sensors and others for mycotoxin detection with a reference to label and label free methods, synthesis of new materials including nano dimension, and transuding techniques. Technological aspects in the development of biosensors for mycotoxin detection, current challenges and future prospects are also included to provide a overview and suggestions for future research directions.

Abstract
OBJECTIVE Prediction of mortality among newborns on mechanical ventilation is difficult. Our aim was to develop a scoring system for predicting mortality among such neonates. METHODS This multi centre prospective study was performed to develop and validate a scoring system among two equal cohorts of ventilated newborns in India. Mechanical ventilator was used in pressure-limited time-cycled mode. Arterial blood gas, initial pulmonary pressures, septicemia screen along with other basic parameters were recorded in a pre-structured proforma. Blood samples were analyzed for malondialdehyde to determine the possible role and predictive validity of free radical injury. Multiple logistic regression analysis was done to find out independent predictors of mortality for the variables those were significantly associated with outcome after univariate analysis. RESULTS On univariate analysis, birth-weight, oxygenation-index, septicaemia, malondialdehyde level, and inotropic support were significantly associated with mortality. However, after multiple regression analysis gestational-age, pH and FiO2 lost their significance as predictors. According to cut-off values of ROC-curve, a scoring system ranging from 0 to 20 and four mortality risk groups were developed. Area under ROC-curve was 0.94, compared to 0.90 for both APACHE-III and CRIB-scores; and 0.92 for PRISM-score. CONCLUSIONS Birth-weight, oxygenation-index, malondialdehyde level, inotropic support, and septicemia are independent mortality predictors of neonatal ventilation. Increase in malondialdehyde level is associated with higher mortality rate, indicating possible role of free radical injury. Pediatr Pulmonol. 2015; 50:271-275. © 2014 Wiley Periodicals, Inc.

Abstract
OBJECTIVE Anatomical changes during radiotherapy (RT) might introduce discrepancies between planned and delivered doses. This study evaluates the need for adaptive treatment in lung cancer RT. METHODS 15 patients with non-small-cell lung cancer, undergoing radical RT with or without concurrent chemotherapy, consecutively underwent planning CT scans at baseline and after 44-46 Gy. Target volumes were delineated on both scans. Phase I delivered 44-46 Gy to the initial planning target volume (PTV). Two Phase II plans for 16-20 Gy were developed on initial and mid-treatment scans, the treatment being delivered with the mid-treatment plan. The second CT structure set was fused with the initial scan data set using dose wash. Volumetric and dosimetric changes in target volumes and critical structures were assessed. RESULTS There was significant reduction in primary gross tumour volume (34.00%; p = 0.02) and PTV (34.70%; p < 0.01) in the second scan. In Plan 2, delivering the same dose to the initial PTV would have resulted in a significantly higher dose to the lung PTV (V20, 52.18%; V5, 21.76%; mean, 23.93%), contralateral lung (mean, 29.43%), heart (V10, 81.47%; V5, 56.62%; mean, 35.21%) and spinal cord (maximum dose, 37.53%). CONCLUSION Treatment replanning can account for anatomical changes during RT and thereby enable better normal tissue sparing, while allowing radical target doses with the possibility of maximizing local control. ADVANCES IN KNOWLEDGE This study supports the sparse dosimetric data regarding the quantitative tumour volume reduction, re-emphasizing the need for adaptive replanning for minimizing normal tissue toxicity without compromising local control, and adds to the existing body of literature.

Abstract
A novel nanobiocomposite bienzymatic amperometric cholesterol biosensor, coupled with cholesterol oxidase (ChOx) and horseradish peroxidase (HRP), was developed based on the gold-nanoparticle decorated graphene-nanostructured polyaniline nanocomposite (NSPANI-AuNP-GR) film which was electrochemically deposited onto indium-tin-oxide (ITO) electrode from the nanocomposite (NSPANI-AuNP-GR) dispersion, as synthesized by in situ polymerization technique. The gold nanoparticle-decorated graphene-nanostructured polyaniline nanocomposite (NSPANI-AuNP-GR) offers an efficient electron transfer between underlining electrode and enzyme active center. The bienzymatic nanocomposite bioelectrodes ChOx-HRP/NSPANI-AuNP-GR/ITO have exhibited higher sensitivity, linearity, and lower Km value than monoenzymatic bioelectrode (ChOx/NSPANI-AuNP-GR/ITO). It is inferred that bienzyme-based nanobioelectrodes offer wider linearity (35 to 500 mg/dL), higher sensitivity (0.42 μAmM−1), low km value of 0.01 mM and higher accuracy for testing of blood serum samples than monoenzyme system. Mechanism of the overall biochemical reaction has been proposed to illustrate the enhanced biosensing performance of the bienzyme system. The novelty of the electrode lies on reusability, extended shelf life, and accuracy of testing blood serum samples.

Abstract
Coronary artery disease (CAD) is one of the leading causes of death worldwide that is influenced by both environmental as well as genetic factors. Several recent genome-wide association studies (GWAS) have reported the association of multiple single nucleotide polymorphisms (SNPs) mainly in the 9p21 region with CAD. However, the association of these SNPs with CAD has not been rigorously tested in Indian population, which accounts for the largest incidences of CAD in the world. Herein, we genotyped six such SNPs (rs10116277, rs10757274, rs1333040, rs2383206, rs2383207 and rs1994016) identified through GWAS, in 754 individuals (311 angiography-confirmed CAD patients and 443 treadmill test controls) recruited mainly from North India to evaluate if these SNPs were associated with CAD. The minor allele frequency of these six SNPs was comparable to that reported in the respective GWAS. We found that three of these SNPs (rs10116277, rs1333040 and rs2383206) present at the locus 9p21 were significantly associated with CAD even after controlling for the confounding factors such as age, sex, body mass index, homocysteine, hypertension, diabetes, smoking, diet, etc. In conclusion, the locus 9p21 found to be significantly associated with cardiovascular diseases in the Caucasian populations seems to be also important in North Indian population.
