Abstract
The present study is designed to assess the antioxidant and antitumor potential of luteolin against benzo(a)pyrene [B(a)P]-induced lung carcinogenesis in Swiss albino mice. Here, we reported that oral administration of B(a)P (50mg/kg body weight) to mice resulted in raised lipid peroxides (LPO), lung specific tumor markers such as carcinoembryonic antigen (CEA) and neuron specific enolase (NSE) with concomitant decrease in the levels of both enzymatic antioxidants such as superoxide dismutase (SOD), catalase (CAT), glutathione reductase (GR), glutathione peroxidase (GPx) and glutathione-s-transferase (GST), and non-enzymatic antioxidants such as reduced glutathione (GSH), vitamin E and vitamin C. Luteolin treatment (15mg/kg body weight, p.o) significantly counteracted all these alterations and maintained cellular normalcy. Moreover, assessment of protein expression levels by western blot analysis revealed that luteolin treatment effectively negates B(a)P-induced upregulated expression of proliferating cell nuclear antigen (PCNA), cytochrome P450 1A1 (CYP1A1) and nuclear factor-kappa B (NF-κB). Furthermore, histopathology of lung tissue and immunohistochemistry of CYP1A1 were carried out to substantiate the anti- lung cancer effect of luteolin. Overall, these findings confirm the chemopreventive potential of luteolin against B(a)P induced lung carcinogenesis.

Abstract
Preclinical models with high prognostic power are a prerequisite for translational research. The closer the similarity of a model to myocardial infarction (MI), the higher is the prognostic value for clinical trials. An ideal MI model should present cardinal signs and pathology that resemble the human disease. The increasing understanding of MI stratification and etiology, however, complicates the choice of animal model for preclinical studies. An ultimate animal model, relevant to address all MI related pathophysiology is yet to be developed. However, many of the existing MI models comprising small and large animals are useful in answering specific questions. An appropriate MI model should be selected after considering both the context of the research question and the model properties. This review addresses the strengths, and limitations of current MI models for translational research.

Abstract
A mouse model of depression has been recently developed by exogenous corticosterone (CORT) administration, which has shown to mimic HPA-axis induced depression-like state in animals. The present study aimed to examine the antidepressant-like effect and the possible mechanisms of resveratrol, a naturally occurring polyphenol of phytoalexin family, on depressive-like behavior induced by repeated corticosterone injections in mice. Mice were injected subcutaneously (s.c.) with 40mg/kg corticosterone (CORT) chronically for 21days. Resveratrol and fluoxetine were administered 30min prior to the CORT injection. After 21-days treatment with respective drugs, behavioral and biochemical parameters were estimated. Since brain derived neurotrophic factor (BDNF) has been implicated in antidepressant activity of many drugs, we also evaluated the effect of resveratrol on BDNF in the hippocampus. Three weeks of CORT injections in mice resulted in depressive-like behavior, as indicated by the significant decrease in sucrose consumption and increase in immobility time in the forced swim test and tail suspension test. Further, there was a significant increase in serum corticosterone level and a significant decrease in hippocampus BDNF level in CORT-treated mice. Treatment of mice with resveratrol significantly ameliorated all the behavioral and biochemical changes induced by corticosterone. These results suggest that resveratrol produces an antidepressant-like effect in CORT-induced depression in mice, which is possibly mediated by rectifying the stress-based hypothalamic-pituitary-adrenal (HPA) axis dysfunction paradigm and upregulation of hippocampal BDNF levels.

Abstract
Lung cancer is the major cause of overall cancer deaths, and chemoprevention is a promising strategy to control this disease. Benzo(a)pyrene [B(a)P], a polycyclic aromatic hydrocarbon, is one among the principal constituents of tobacco smoke that plays a key role in lung carcinogenesis. The B(a)P induced lung cancer in mice offers a relevant model to study the effect of natural products and has been widely used by many researchers and found considerable success in ameliorating the pathophysiological changes of lung cancer. Currently available synthetic drugs that constitute the pharmacological armamentarium are themselves effective in managing the condition but not without setbacks. These hunches have accelerated the requisite for natural products, which may be used as dietary supplement to prevent the progress of lung cancer. Besides, these agents also supplement the conventional treatment and offer better management of the condition with less side effects. In the context of soaring interest toward dietary phytochemicals as newer pharmacological interventions for lung cancer, in the present review, we are attempting to give a silhouette of mechanisms of B(a)P induced lung carcinogenesis and the role of dietary phytochemicals in chemoprevention.

Abstract
Diabetic nephropathy is a serious microvascular complication for patients associated with diabetes mellitus. Recent studies have suggested that NF-κB is the main transcription factor for the inflammatory response mediated progression of diabetic nephropathy. Hence, the present study is hypothesized to explore the renoprotective nature of BAY 11-7082 an IκB phosphorylation inhibitor on Streptozotocin (STZ) induced diabetic nephropathy in Sprague-Dawley (SD) rats. Male SD rats were divided into five groups, group I sham control, group II drug control, group III diabetic control (STZ 50mg/kg), group IV and V are test drug groups to which a single dose of STZ 50mg/kg was injected initially and later received BAY 11-7082 1mg/kg and 3mg/kg, respectively from 5th to 8th week. Eight weeks after STZ injection, diabetic rats exhibited significant renal dysfunction, as evidenced by reduced creatinine clearance, increased blood glucose, urea nitrogen and creatinine, which were reversed to near normal by BAY 11-7082. BAY 11-7082 treated rats showed significant improvement in the decreased enzymatic antioxidant SOD, non-enzymatic antioxidant GSH levels, and elevated lipid peroxidation and nitric oxide levels as observed in the diabetic rats. BAY 11-7082 treatment was found to significantly recover kidney histological architecture in the diabetic rats. Altered levels of inflammatory cytokines like TNF-α, IL-1β, IL-6 and nuclear transcriptional factor subunit NF-κB p65 were reverted to the normal level upon treatment with BAY 11-7082. Our results suggest that by limiting the activation of NF-κB, thereby reducing the expression of inflammatory cytokines and by inhibiting the oxidative damage BAY 11-7082 protect the rats against diabetic nephropathy.

Abstract
OBJECTIVE The main objective of the present study was to explore the antitumor activity of the ethyl acetate extract of the Alternanthera brasiliana (EAAB) and its antioxidant status against Ehrlich ascites carcinoma (EAC) in Swiss albino mice. MATERIALS AND METHODS Based on the preliminary in vitro cytotoxicity studies, EAAB was selected for anti-tumor and antioxidant effects. Anticancer activity of EAAB was evaluated against EAC in Swiss albino mice at the doses of 200 and 400 mg/kg. EAAB was administered for 14 consecutive days after induction of cancer. After 24 h of the last dose and 18 h of fasting, half of the mice were sacrificed and rest were kept alive for assessing any increase in life span. The antitumor effect of EAAB was assessed by evaluating tumor volume, viable and nonviable tumor cell count, tumor weight, hematological and biochemical parameters of EAC bearing host. Furthermore, the antioxidant and histopathological parameters were evaluated. RESULTS EAAB treatment has shown significant decrease in tumor volume, viable cell count, tumor weight and elevated the life span of EAC tumor bearing mice in a dose dependent manner. In hematological profile count of RBC, hemoglobin, and WBC were found reverted to normal. EAAB also significantly decreased the levels of lipid peroxidation and significantly increased the levels of GSH, SOD and Catalase. CONCLUSION From the above results it may be concluded that EAAB has potent dose dependent antitumor activity and is comparable to that of 5-flourouracil.

Abstract
Natural Killer (NK) cells are innate immune effectors that are primarily involved in immunosurveillance to spontaneously eliminate malignantly transformed and virally infected cells without prior sensitization. NK cells trigger targeted attack through release of cytotoxic granules, and secrete various cytokines and chemokines to promote subsequent adaptive immune responses. NK cells selectively attack target cells with diminished major histocompatibility complex (MHC) class I expression. This "Missing-self" recognition by NK cells at first puzzled researchers in the early 1990s, and the mystery was solved with the discovery of germ line encoded killer immunoglobulin receptors that recognize MHC-I molecules. This review summarizes the biology of NK cells detailing the phenotypes, receptors and functions; interactions of NK cells with dendritic cells (DCs), macrophages and T cells. Further we discuss the various strategies to modulate NK cell activity and the practice of NK cells in cancer immunotherapy employing NK cell lines, autologous, allogeneic and genetically engineered cell populations.

Abstract
The highly conserved abundant nuclear protein poly(ADP-ribose)polymerase1 (PARP1) functions at the center of cellular stress response and is mainly implied in DNA damage repair mechanism. Apart from its involvement in DNA damage repair, it does sway multiple vital cellular processes such as cell death pathways, cell aging, insulator function, chromatin modification, transcription and mitotic apparatus function. Since brain is the principal organ vulnerable to oxidative stress and inflammatory responses, upon stress encounters robust DNA damage can occur and intense PARP1 activation may result that will lead to various CNS diseases. In the context of soaring interest towards PARP1 as a therapeutic target for newer pharmacological interventions, here in the present review, we are attempting to give a silhouette of the role of PARP1 in the neurological diseases and the potential of its inhibitors to enter clinical translation, along with its structural and functional aspects.

Abstract
Cancer chemoprevention is a strategy taken to block, reverse or retard the multistep process of carcinogenesis, including the blockage of its vital morphogenetic milestones viz. normal-preneoplasia-neoplasia-metastasis. Naturally occurring phytochemicals are becoming increasingly popular over synthetic drugs for several reasons, including safety, efficacy and easy availability. Nimbolide, a triterpene derived from the leaves and flowers of neem, is widely used in traditional medical practices for treating various human ailments. The neem limonoid exhibits multiple pharmacological effects among which its anticancer activity is the most promising. The preclinical and mechanistic studies carried over the decades have shown that nimbolide inhibits tumorigenesis and metastasis without any toxicity and unwanted side effects. Nimbolide exhibits anticancer activity through selective modulation of multiple cell signaling pathways linked to inflammation, survival, growth, invasion, angiogenesis and metastasis. The present review highlights the current knowledge on molecular targets that contribute to the observed anticancer activity of nimbolide related to (i) inhibition of carcinogenic activation and induction of antioxidant and carcinogen detoxification enzymes, (ii) induction of growth arrest and apoptosis; and (iii) suppression of proinflammatory signaling pathways related to cancer progression.

Abstract
Meditation is a complex mental practice involving changes in sensory perception, cognition, hormonal and autonomic activity. It is widely used in psychological and medical practices for stress management as well as stress mediated mental disorders like depression. A growing body of literature has shown that meditation has profound effects on numerous physiological systems that are involved in the pathophysiology of major depressive disorder (MDD). Although meditation-based interventions have been associated with improvement in depressive symptoms and prevention of relapse, the physiological mechanisms underlying the therapeutic effects of meditation are not clearly defined and even paradoxical. This paper reviews many of the physiological abnormalities found in cytokine & stress mediated depression and the reversal of these anomalies by different meditation techniques.
