Abstract
In India, newborn screening (NBS) is essential for detecting health problems in infants. Despite significant progress, significant gaps and challenges persist. India has made great strides in genomics dueto the existence of the National Institute of Biomedical Genomics in West Bengal. The work emphasizes the challenges NBS programs confront with technology, budgetary constraints, insufficient counseling, inequality in illness panels, and a lack of awareness. Advancements in technology, such as genetic testing and next-generation sequencing, are expected to significantly transform the process. The integration of analytical tools, artificial intelligence, and machine learning algorithms could improve the efficiency of newborn screening programs, offering a personalized healthcare approach. It is critical to address gaps in information, inequities in illness incidence, budgetary restrictions, and inadequate counseling. Strengthening national NBS programs requires increased public awareness and coordinated efforts between state and central agencies. Quality control procedures must be used at every level for implementation to be successful. Additional studies endeavor to enhance NBS in India through public education, illness screening expansion, enhanced quality control, government incentive implementation, partnership promotion, and expert training. Improved neonatal health outcomes and the viability of the program across the country will depend heavily on new technology and counseling techniques.

Abstract
Bisphenol-A (BPA) is widely used in food packaging and household products, leading to daily human exposure and potential health risks including metabolic diseases like type 2 diabetes mellitus (T2DM). Understanding BPA's mechanisms and developing intervention strategies is urgent. Centella asiatica, a traditional herbal medicine containing pentacyclic triterpenoids, shows promise due to its antioxidant and anti-inflammatory properties, utilized for centuries in Ayurvedic therapy. We investigated the effect of Centella asiatica (CA) ethanol extract on BPA-induced pancreatic islet toxicity in male Swiss albino mice. BPA administration (10 and 100 μg/kg body weight, twice daily) for 21 days caused glucose homeostasis disturbances, insulin resistance, and islet dysfunction, which were partially mitigated by CA supplementation (200 and 400 mg/kg body weight). Additionally, heightened oxidative stress, elevated levels of proinflammatory cytokines, loss of mitochondrial membrane potential (MMP), abnormal cell cycle, and increased apoptosis were implicated in the detrimental impact of BPA on the endocrine pancreas which were effectively counteracted by CA supplementation. In summary, CA demonstrated a significant ability to mitigate BPA-induced apoptosis, modulate redox homeostasis, alleviate inflammation, preserve MMP, and regulate the cell cycle. As a result, CA emerged as a potent agent in neutralizing the diabetogenic effects of BPA to a considerable extent.

Quercetin counteracts monosodium glutamate to mitigate immunosuppression in the thymus and spleen via redox-guided cellular signaling. Phytomedicine 2024; 126:155226.

Abstract
BACKGROUND Chronic inflammation brought on by oxidative stress can result in several immunopathologies. Natural compounds with antioxidant characteristics, like quercetin, have shown effectiveness in reducing oxidative damage and regulating the immune response. PURPOSE The commonly used food additive monosodium glutamate (M) causes immunosuppression by disrupting redox equilibrium and inducing oxidative stress. The goal of this work is to examine the therapeutic potential of quercetin against immunotoxicity brought on by M, revealing the molecular route implicated in such immunopathology by targeting the thymus and spleen, to support the development of future anti-inflammatory and antioxidant therapies. STUDY DESIGN AND METHODS M-fed rats were employed as an immunotoxicity model and were supplemented with quercetin for four weeks. Hematological and biochemical parameters were measured; H&E staining, immunohistochemistry, flow cytometry, real-time quantitative PCR, and western blotting were performed. RESULTS Based on the findings, TLR4 was activated by M to cause oxidative stress-mediated inflammation, which was alleviated by the supplementation of quercetin by modulating redox homeostasis to neutralize free radicals and suppress the inflammatory response. To prevent M-induced inflammation, quercetin demonstrated anti-inflammatory functions by blocking NF-kB activation, lowering the production of pro-inflammatory cytokines, and increasing the release of anti-inflammatory cytokines. By normalizing lipid profiles and lowering the potential risk of immunological deficiency caused by M, quercetin also improves lipid metabolism. Additionally, it has shown potential for modifying insulin levels, suggesting a possible function in controlling M-induced alteration in glucose metabolism. The addition of quercetin to M enhanced the immune response by improving immunoglobulin levels and CD4/CD8 expression in the thymus and spleen. Additionally, quercetin inhibited apoptosis by controlling mitochondrial caspase-mediated cellular signaling, suggesting that it may be able to halt cell death in M-fed rats. CONCLUSION The results of this study first indicate that quercetin, via modulating redox-guided cellular signaling, has a promising role in reducing immune disturbances. This study illuminates the potential of quercetin as a safe, natural remedy for immunopathology caused by M, including thymic hypoplasia and/or splenomegaly, and paves the way for future anti-inflammatory and antioxidant supplements.

Abstract
BACKGROUND The most widely used food additive monosodium glutamate (MSG) has been linked to immunopathology. Conversely, quercetin (Q), a naturally occurring flavonoid has been demonstrated to have immunomodulatory functions. Therefore, the purpose of the study is to determine if quercetin can mitigate the deleterious effects of MSG on immune cells, and the possible involvement of TLR, if any. METHODS AND RESULTS: This study was conducted on Q, to determine how it affects the inflammatory response triggered by MSG in primary cultured thymocytes and splenocytes from rats (n = 5). Q shielded cells by augmenting cell survival and decreasing lactate dehydrogenase leakage during MSG treatment. It decreased IL-1β, IL-6, IL-8, and TNF-α expression and release by hindering NF-kB activation and by inhibiting the JAK/STAT pathway. Moreover, Q prevented NLRP3 activation, lowered IL-1β production, and promoted an anti-inflammatory response by increasing IL-10 production. Q reduced MSG-induced cellular stress and inflammation by acting as an agonist for PPAR-γ and LXRα, preventing NF-kB activation, and lowering MMP-9 production via increasing TIMP-1. Additionally, Q neutralized free radicals, elevated intracellular antioxidants, and impeded RIPK3, which is involved in inflammation induced by oxidative stress, TNF-α, and TLR agonists in MSG-treated cells. Furthermore, it also modulated TYK2 and the JAK/STAT pathway, which exhibited an anti-inflammatory effect. CONCLUSIONS MSG exposure is associated with immune cell dysfunction, inflammation, and oxidative stress, and Q modulates TLR to inhibit NF-kB and JAK/STAT pathways, providing therapeutic potential. Further research is warranted to understand Q's downstream effects and explore its potential clinical applications in inflammation.

Abstract
The estrogenic impact of Bisphenol-A (BPA), a widely recognized endocrine disruptor, causes disruption of pancreatic β-cell function through estrogen receptors (ERs). While BPA's binding affinity for ERs is significantly lower than that of its natural counterpart, estrogen, recent observations of BPA's affinity for aryl hydrocarbon receptor (AhR) in specific cellular contexts have sparked a specific question: does AhR play a role in BPA's toxicological effects within the endocrine pancreas? To explore this question, we investigated BPA's (10 and 100 μg/ kg body weight/day for 21 days) potential to activate AhR within pancreatic islets and assessed the protective role of ethanol extract of Centella asiatica (CA) (200 and 400 mg/kg body weight/day for 21 days) against BPA-mediated toxicity in mouse model. Our results indicate that BPA effectively triggers the activation of AhR and modulates its target genes within pancreatic islets. In contrast, CA activates AhR but directs downstream pathways differentially and activates Nrf2. Additionally, CA was observed to counteract the disruption caused by BPA in glucose homeostasis and insulin sensitivity. Furthermore, BPA-induced oxidative stress and exaggerated production of proinflammatory cytokines were effectively counteracted by CA supplementation. In summary, our study suggests that CA influenced AhR signaling to mitigate the disrupted pancreatic endocrine function in BPA exposed mice. By shedding light on how BPA interacts with AhR, our research provides valuable insights into the mechanisms involved in the diabetogenic actions of BPA.

Abstract
Context Lathe machine work is an important unorganized sector in India. However, to date, no work physiological studies have been conducted among these workers to evaluate the physical strain involved in this work. Aim The present study aims to determine the workload in different lathe machine tasks from working heart rates (HRs) and certain cardiac indices. Settings and Design A cross-sectional study was conducted among 38 full-time male workers aged between 21 and 60 years. Methods and Materials The HR was measured directly during the productive work phase, additional work phase, and work pauses. Two cardiac strain indices, viz., net cardiac cost and relative cardiac cost were derived. The workload was also judged according to some standard acceptable criteria of physical strain. Statistical Analysis Used Mean and standard deviation were obtained for different categories of HR. Intergroup comparisons were conducted through one-way analysis of variance and the t-test. Results The mean working HR was found to be 99 beats per minute. A maximal working HR of 105 ± 6.1 beats per minute with a corresponding relative cardiac cost of 26% was obtained during the additional work phase. Conclusions The overall workload appeared to be moderate in nature. An acceptable criterion of cardiac cost of 30% appeared to be the most sensitive index in detecting workers experiencing a higher level of physical strain.

Abstract
Abstract
Globally, the trend of using food additives and eating ready-made fast food has led to a deleterious impact on immune organs. Monosodium glutamate (MSG), as a food additive in a high-lipid diet (HLD), acts as a silent killer of immune cells. Hence, the present study aimed to evaluate the role of MSG in HLD on spleen injury in rats. Results showed that a 2.52-fold and 1.91-fold increase in spleen index in MSG and MSG + HLD group indicates splenomegaly, whereas a 1.36-fold and 1.29-fold increase in pro-inflammatory cytokines in MSG and MSG + HLD-fed rats, respectively, promote the inflammatory response. Additionally, MSG and MSG + HLD induce oxidative stress by 1.81-fold and 1.1-fold increased generation of reactive oxygen species (ROS) in macrophage population, and 1.38-fold and 1.36-fold increased generation of ROS in lymphocytes population, respectively. Furthermore, mitochondrial membrane potential was significantly reduced by 1.43-fold and 1.18-fold in MSG and MSG + HLD groups. Therefore, the current study argues that MSG has more detrimental effects on the spleen than MSG + HLD due to the presence of antioxidants in HLD, which suppresses the deleterious impact of MSG. Hence, it can be inferred that MSG induces spleen injury via targeting redox-guided cellular signaling with inflammatory response, leading to severe immune system anomalies.

Abstract
People in the fast-food era rely on pre-packaged foods and engage in limited physical activity, which leads to a shift in eating patterns. Monosodium glutamate (MSG), a dietary ingredient used in this sort of cuisine, has been found to be hazardous to both experimental animals and humans. The objective of this study was to explore at the unnecessary changes caused by consuming MSG in secret and exceeding the recommended dosage. Hence, we decided to evaluate the impact of MSG by using three different doses (200, 400, and 600 mg/kg body weight orally) for 28 days in rats. We uncovered that all three MSG dosages result in a rise in body weight, dyslipidemia, inflammatory response, and hepato-cardiac marker enzymes, all of which imply hepatic and cardiac toxicity. Furthermore, changes in redox status suggest oxidative stress, which was higher in all three MSG dosages although not as much as in the MSG-600 group when compared to control. Such effects eventually manifested themselves in tissue architecture of the liver and heart, resulting in severe hepato-cardiac derangement, but the degree of tissue damage was greater in the MSG-600 group. As a result, it is possible that MSG has a negative influence on the liver and heart. However, the MSG-600 group showed a substantial effect, indicating that MSG should not be used in food preparation. Therefore, the findings of the study may aid in the formulation of health-care strategies and serve as a warning to the general public regarding the use of MSG in daily diet.

Abstract
Dichlorophene (DCP) is a halogenated phenolic compound, widely used as fungicide, bactericide and antiprotozoan and also exhibit therapeutic application in several pathological conditions. Taking account of broad use of DCP, its possible effect on spleen (an important immune organ) was investigated in this study. Male albino rats were treated with graded doses of DCP (10%, 20% and 30% of LD50) and spleen and blood were obtained at 24, 48 and 72 hours post treatment. Oxidative stress parameters, proinflammatory cytokines and protein expression of aryl hydrocarbon receptor (AhR), indoleamine-2, 3-Dioxygenase 1 (IDO1) and nuclear factor erythroid 2-related factor 2 (Nrf2) were measured along with histopathological evaluation of spleen. In the present study, DCP perturbs redox status of splenocytes of rats as evidenced by excess ROS generation, lipid peroxidation and nitric oxide production simultaneously with reduction of antioxidant level [glutathione (GSH)] and inhibition of antioxidative enzymes [superoxide dismutase (SOD) and catalase (CAT)]. Two important proinflammatory cytokines, IL-6 and TNF-α were found to be elevated upon DCP treatment. Moreover, DCP also caused activation of AhR and IDO1 with simultaneous down regulation of Nrf2. All these effects of DCP were found to be dose and duration dependent. DCP also affects the spleen micro-architecture in the present study and these alterations were more prominent in high dose group at 72 hours post treatment. Taken together, all these results suggested that DCP induces oxidative stress and also increases proinflammatory cytokine levels to mount its toxic effect on spleen.

Abstract
Flavor enhancing high lipid diet acts as silent killer. Monosodium glutamate mixed with high lipid diet alters redox-status. Monosodium glutamate mixed with high lipid diet induces systemic anomalies.
In this fast-food era, people depend on ready-made foods and engage in minimal physical activities that ultimately change their food habits. Majorities of such foods have harmful effects on human health due to higher percentages of saturated fatty acids, trans-fatty acids, and hydrogenated fats in the form of high lipid diet (HLD). Moreover, food manufacturers add monosodium glutamate (MSG) to enhance the taste and palatability of the HLD. Both MSG and HLD induce the generation of reactive oxygen species (ROS) and thereby alter the redox-homeostasis to cause systemic damage. However, MSG mixed HLD (MH) consumption leads to dyslipidemia, silently develops non-alcoholic fatty liver disease followed by metabolic alterations and systemic anomalies, even malignancies, via modulating different signaling pathways. This comprehensive review formulates health care strategies to create global awareness about the harmful impact of MH on the human body and recommends the daily consumption of more natural foods rich in antioxidants instead of toxic ingredients to counterbalance the MH-induced systemic anomalies.

Abstract
Since prehistoric times Coccinia grandis has been used as traditional medicine for various diseases including diabetes, dyslipidemia, metabolic and digestive disorders. Although the rationality of efficacy as natural antioxidants with different bioactive compounds in Coccinia grandis against monosodium glutamate (MSG) induced hepato-cardiac damage remains to be disclosed. Six different solvent extracts of the leaves of Coccinia grandis were chosen to evaluate in vitro antioxidant and free radical (FR)-scavenging activity. Due to high antioxidant content and FR-scavenging property of ethanol extract of Coccinia grandis leaves (EECGL) and presence of different bioactive compounds in EECGL was further tested to evaluate in vivo hepato-protective and cardio-protective efficacy against MSG-induced anomalies. MSG-induced dyslipidemia, increased cell toxicity markers altered functional status and histopathological peculiarities of target organs were blunted by EECGL. Additionally, MSG incited increase level of interleukin (IL)-6, tumour necrosis factor (TNF)-α, IL-1β which activates nuclear factor kappa-B (NF-kB) guided inflammation via down regulation of IL-10; impaired redox-homeostasis subsequently promoted inflammation associated oxidative stress (OS) and increased vascular endothelial growth factor (VEGF) which provoked microvascular proliferation related cellular damage. On the contrary, increased lipid peroxidation and nitric oxide promotes reduced cell viability, deoxyribonucleic acid damage and apoptosis via activation of caspase 3. EECGL significantly reduced MSG-induced inflammation mediated OS and apoptosis via inhibition of pro-inflammatory factors and pro-apoptotic mediators to protect liver and heart. Therefore, it can be suggested that EECGL contributed competent scientific information to validate the demands for its use to treat MSG-induced hepato-cardiac OS mediated inflammation and apoptosis from natural origin.

Abstract
OBJECTIVES Terminalia arjuna (TA) has been widely used as folk medicine since ancient times. Apart from its therapeutic properties it also has anti-spermatogenic activity, but its effectiveness and mode of action on male gonadal activity remains to be revealed. METHODS TA bark extract was dissolved in 1% dimethyl sulfoxide and applied in primary Leydig cell culture from rat testis in dose dependent manner. After 24 h of treatment cellular toxicity marker, cytokines, steroid 5-alpha-reductase 1 (SRD5A1) and androgen receptor (AR) were measured. RESULTS Present study first proposed the cytotoxic impacts of TA on Leydig cells via leakage of lactate dehydrogenase and inflammatory responses by altering the pro- and anti-inflammatory cytokines in dose-dependent-manner. Furthermore, down regulation of SRD5A1 and AR indicated inhibition of normal steroidogenesis which well corroborated with cytotoxity and inflammation related parameters to promote damage of Leydig cell function. Nevertheless, it can be speculated that the inhibition of normal steroidogenesis and thereby spermatogenesis induced by TA is possibly due to the presence of β-sitosterol. CONCLUSIONS Therefore, the dose and duration of treatment should be carefully monitored in cases of its medicinal uses and longer duration should be avoided to protect reproductive health and fertility.

Abstract
Introduction and Aim: Cigarette smoking, one of the fundamental roots of preventable morbidity, has a myriad of notorious effects. Nicotine is the most bountiful and symbolic constituent of cigarette smoke. The liaison between smoking and infertility has been investigated for decades; but it’s still dubious whether the noxious effects of cigarette smoking on testis and sperm characteristics are by virtue of nicotine. Therefore, the current study interrogated the ameliorative effects of folic acid and vitamin B12 on nicotine induced catastrophe in testicular tissue and sperm characters in male albino rats.
Materials and Methods: Rats were treated with nicotine (3 mg/kg body weight/day, intraperitoneal) with or without folic acid (36µg/kg body weight/day, orally) and vitamin B12 (0.63µg/kg body weight/ day, orally) for 21 days. Sperm qualities were analyzed for motility and morphology. Various oxidative and anti- oxidative stress parameters, pro inflammatory cytokines levels, hormonal assays were performed.
Results: Findings marked that nicotine caused degenerative changes in the testicular tissue. Supplementation with folic acid and vitamin B12 reversed these results along with suppressing the nicotine induced changes in TNF- ?, IL-6, and markers of oxidative stress. Moreover, folic acid and vitamin B12 in combination also significantly blunted the altered activities of testicular key androgenic enzymes, plasma levels of testosterone, LH, and FSH following nicotine exposure.
Conclusion: In closure, testimonies manifested that folic acid and vitamin B12 may act as plausible strategy against oxidative stress, which is a pivotal step in nicotine-induced reproductive toxicity, and bettering functional status of testicular tissue by scavenging free radicals and hindering the generation of pro- inflammatory cytokines.

Abstract
Context: Alteration of redox signalling and RANK-L expression in FBMCs of mice exposed to different intensities of cold stress (15 °C, 8 °C and 4 °C) were studied.Objective: To understand the effects of varying intensities of cold stress on murine FBMCs and its impact on osteoclastogenesis.Materials and methods: FBMCs were isolated from mice exposed to different intensities of cold stress and used for immunoblotting and biochemical assays. Bone histometry was also done.Results: Different intensities of cold stress perturb redox signalling in FBMCs and alters bone histometry. Higher RANK-L expressions were noted in FBMCs of mice exposed to 8 °C and 4 °C as compared with 15 °C.Discussion and conclusion: Cold stress boosts free radical production in FBMC's, which might enhance RANK-L expression, an indicator of osteoclastogenesis. Thus, we speculate that stronger cold stress (8 °C and 4 °C) contributes to the development of early bone loss.

Abstract
In the context of failure of treatment for non alcoholic fatty liver disease (NAFLD)-mediated systemic damages, recognition of novel and successful characteristic drug to combat these anomalous situations is earnestly required. The present study is aimed to evaluate protective value of ethanol extract of Coccinia grandis leaves (EECGL), naturally occurring medicinal plant, on NAFLD-mediated systemic damage induced by high lipid diet along with monosodium glutamate (HM)-fed rats. Our study uncovered that EECGL significantly ameliorates HM-induced hyperlipidemia, increased lipogenesis and metabolic disturbances (via up regulation of PPAR-α and PPAR-γ), oxidative stress (via reducing the generation of reactive oxygen species and regulating the redox-homeostasis) and inflammatory response (via regulating the pro-inflammatory and anti-inflammatory factors with concomitant down regulation of NF-kB, iNOS, TNF-α and up regulation of eNOS). Furthermore, EECGL significantly inhibited HM-induced increased population of cells in sub G0/G1 phase, decreased Bcl2 expression and thereby loss of mitochondrial membrane potential with over expression of Bax, p53, p21, activation of caspase 3 and 9 indicated the apoptosis and suppression of cell survival. It is perhaps the first comprehensive study with a mechanistic approach which provides a strong unique strategy for the management of HM-induced systemic damage with effective dose of EECGL.

Abstract
Background In the present era, obesity is increasing rapidly, and high dietary intake of lipid could be a noteworthy risk factor for the occasion of obesity, as well as nonalcoholic fatty liver disease, which is the independent risk factor for type 2 diabetes and cardiovascular disease. For a long time, high-lipid diet (HLD) in "fast food" is turning into part of our everyday life. So, we were interested in fulfilling the paucity of studies by means of preliminary evaluation of these three alternative doses of HLD on a rat model and elucidating the possible mechanism of these effects and divulging the most alarming dose. Methods Thirty-two rats were taken, and of these, 24 were fed with HLD in three distinctive compositions of edible coconut oil and vanaspati ghee in a ratio of 2:3, 3:2 and 1:1 (n = 8), orally through gavage at a dose of 10 mL/kg body weight for a period of 28 days, whereas the other eight were selected to comprise the control group. Results After completion of the experiment, followed by analysis of data it was revealed that hyperlipidemia with increased liver and cardiac marker enzymes, are associated with hepatocellular injury and cardiac damage. The data also supported increased proinflammatory cytokines such as interleukin 6 (IL-6) and tumor necrosis factor α (TNF-α). As oxidative stress parameter increased in both liver and heart, there is also an increased in TNF-α due to an increased expression of inducible nitric oxide (NO) synthase, which led to a high production of NO. Moreover, HLD treatment explicitly weakens reasonability of hepatocytes and cardiomyocytes conceivably through G0/G1 or S stage capture or perhaps by means of enlistment of sub-G0/G1 DNA fragmentation and a sign of apoptosis. Conclusions Based on the outcomes, it tends to be inferred that consequences of the present examination uncovered HLD in combination of 2:3 applies most encouraging systemic damage by reactive oxygen species generation and hyperlipidemia and necroapoptosis of the liver and heart. Hence, outcome of this study may help to formulate health care strategy and warns about the food habit in universal population regarding the use of hydrogenated and saturated fats (vanaspati ghee) in diet.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Tinospora sinensis Lour. (Merr.) belongs to the family Menispermaceae and its stem extract have been used traditionally in broad aspects of therapeutic remedies including debility, dyspepsia, fever, jaundice, ulcer, bronchitis, urinary disease, skin disease, liver disease and diabetes. AIM OF THE STUDY The aim of the study was to evaluate the protective effects of methanol extract of stem of Tinospora sinensis (METS) on streptozotocin induced pancreatic islet cell injuries of diabetic rats and its correlation to its phytochemical profiles. MATERIALS AND METHODS A high-performance liquid chromatography technique (HPLC) was used to identify and quantify the major phytochemicals present in the METS. Diabetic rats were administered with METS at a dose of (100, 200 and 400 mg/kg respectively orally) and standard drug Metformin (300 mg/kg) was given orally to group serving positive control. Effect of the METS on glucose homeostasis, oxidative stress, antioxidant status, histopathology of pancreas and also on intracellular reactive oxygen species (ROS), mitochondrial membrane potential, apoptosis, cell cycle of pancreatic islet cells were studied in diabetic rats. RESULTS The major phytochemicals identified and quantified by HPLC in the extract were berberine, caffeic acid, myricetin and ferulic acid. This result showed that methanol extract exhibited good antioxidant effect. The methanol extract of the plant prevented the diabetogenic effect of STZ and significantly lowered the fasting blood glucose level, glycated haemoglobin and increased insulin and C-peptide level in treated rats. METS reduced apoptosis of STZ treated islet cells by significantly decreasing pro-inflammatory cytokines (TNFα, IL6), intracellular ROS generation, lipid peroxidation, nitric oxide (NO) production and increasing mitochondrial membrane potential and sub-G0 peak area, enzymatic and nonenzymatic antioxidants. CONCLUSION The results revealed that the methanol extract of the stem of the plant possesses protective effects against diabetes and associated complications.

Abstract
Accelerating prevalence of coal workers pneumoconiosis is considered as a serious occupational health problem. This cross-sectional study was designed to determine the prevalence of lung function impairment of underground coal miners in West Bengal, India. A total of 230 underground coal dust-exposed subjects and 130 nonexposed subjects were examined for lung function test and also information on sociodemographic characteristics, addiction, respiratory morbidity, personnel protective equipment and dust exposure were collected. Lung function impairment was significantly higher in exposed group than nonexposed group and personnel dust exposure level were exceeded above the NIOSH recommended level. In addition, respiratory ailments were found to be higher in exposed group than the nonexposed group. So, this study has established the need for an advanced understanding of the quantifiable and measurable remedies for protection of lung disorder of coal mine workers.

Abstract
Exposure to bisphenol A (BPA), an endocrine disruptor and environmental toxicant, is associated with adverse estrogenic effects in both humans and wildlife species. Because the effects of BPA on the ovary at the cellular level are incompletely understood, the present study was designed to investigate the underlying mechanism of granulosa cell injury following BPA exposure. Eight-week-old female Wistar rats were treated with BPA (25 mg/kg BW/day for 9 days, intraperitonially) with or without pretreatment of the catalase-specific blocker 3-amino-1,2,4-triazole (ATZ; 1 g/kg BW/day for 5 days, intraperitonially). Different oxidative and antioxidant stress parameters, pro-inflammatory cytokines, and hormonal levels were measured. Catalase expression in isolated granulosa cells was analyzed by Western blot. There were noticeable increases in both nitric oxide and lipid peroxidation levels in the granulosa cells of the BPA-treated group with or without pretreatment with ATZ. Compared with the controls, BPA exposure resulted in a significant increase in pro-inflammatory cytokine levels that was further increased following pretreatment with ATZ. Results of the hormonal assays clearly showed a significant decrease in both estrogen and progesterone levels. In contrast, there was a significant increase in both serum follicle-stimulating hormone and luteinizing hormone levels following BPA exposure, with or without ATZ pretreatment. Results of Western blot analysis demonstrated decreased expression of catalase in the BPA-treated group and a further decrease in expression in the group treated with both BPA and ATZ. Our data suggest that catalase plays a role in mediating reproductive damage to granulosa cells exposed to BPA.

Abstract
Nicotine, one of the well-known highly toxic components of cigarette smoke, causes a number of adverse health effects and diseases. Our previous study has shown that nicotine induces reactive oxygen species (ROS) in islet cell and disrupts islet cell mitochondrial membrane potential (ΔΨm). However, supplementation with folic acid and vitamin B12 were found effective against nicotine induced changes in pancreatic islet cells. But the toxicological effects and underlying mechanisms of nicotine-induced mitochondrial dysfunction is still unknown. In this study, nicotine exposure decreases mitochondrial enzymes (pyruvate dehydrogenase, alpha-ketoglutarate dehydrogenase, aconitase, malate dehydrogenase) activities by increasing cytosolic Ca2+ level which may contribute to increased mitochondrial ROS production by raising its flow to mitochondria. This in turn produces malondialdehyde and nitric oxide (NO) with a concomitant decrease in the activities of antioxidative enzymes and glutathione levels leading to loss of ΔΨm. Simultaneously, nicotine induces pancreatic islet cell apoptosis by modulating ΔΨm via increased cytosolic Ca2+ level, altered Bcl-2, Bax, cytochrome c, caspase-9, PARP expressions which were prevented by the supplementation of folic acid and vitamin B12 . In conclusion, nicotine alters islet cell mitochondrial redox status, apoptotic machinery, and enzymes to cause disruption in the ΔΨm and supplementation of folic acid and vitamin B12 possibly blunted all these mitochondrial alterations. Therefore, this study may help to determine the pathophysiology of nicotine-mediated islet cell mitochondrial dysfunction.

Abstract
OBJECTIVE Fenvalerate (20% EC) is a synthetic pyrethroid, which is commonly used in India by farmers for the protection of many food and vegetable crops against a wide variety of insects. However, its inhalation toxicity data is very limited in the literature due to the fact that the exposure levels associated with these effects were usually not reported. Hence, inhalation exposure was carried out to investigate the hepatotoxic effects. METHOD Adult male rats were exposed to fen for 4 h/day, 5 days a week for 90 days by using Flow Past Nose Only Inhalation Chamber. Sham treated control rats were exposed to compressed air in the inhalation chamber for the same period. RESULTS The results indicated hepatomegaly, increased activities of serum clinical enzymes (indicative of liver damage/dysfunction) along with pronounced histopathological damage of liver. CONCLUSION The hepatotoxic potential of formulated Fen (20% EC) in rats exposed by nose only inhalation is being reported for the first time and warrant adequate safety measures for human beings exposed to this insecticide, particularly by inhalation route.

Abstract
Fenvalerate (Fen) is a synthetic pyrethroid, which is commonly used for destroying a variety of insect pests damaging several vegetable, fruit, and cotton crops. This insecticide is also used to mitigate household insects like flies, cockroaches, mosquitoes, and so forth. Human beings are exposed to formulated Fen preparations mostly by inhalation during spraying in fields for crop protection, for control of household insects, and also during handling and packaging at manufacturing plants. Limited online information is available regarding toxic effects of formulated Fen exposure on mammalian reproductive system. The present study has been undertaken to investigate male reproductive toxic effects of a formulated preparation of Fen (20% EC) particularly in relation to steroidogenic alterations in testes and sera of rats exposed by nose-only inhalation for (4 hours/day and five days a week) for three months. The results indicate significant reduction in the weight of testes, epididymal sperm counts, and sperm motility, along with decrease in marker testicular enzymes for testosterone biosynthesis viz. 17-beta-hydroxy steroid dehydrogenase (17-beta-HSD) and glucose-6-phosphate dehydrogenase (G6PDH), leading to net decrease in serum testosterone concentration in group of rats exposed to one-fifth LC50 of Fen (20% EC) by inhalation (4 hours/day, five days a week) subchronically for three months. These results for the first time indicate the role of testosterone in Fen (20% EC)-induced male reproductive toxicity of rats subchronically exposed by inhalation probably due to neuroendocrine-mediated phenomenon and hormone-disrupting property of the insecticide.

Abstract
Trichloroethylene (TCE) is widely used as an industrial solvent and cleaning fluid. In the present study the toxic effects of TCE inhalation on pulmonary and hepatic biotransformation enzymes in rats have been investigated by assay of aniline hydroxylase (AH), aminopyrine-N-demethylase (APD), benzo-a-pyrene hydroxylase (BH) and glutathione-s-transferase (GST) activities and glutathione (GSH) contents in liver as well as lungs of exposed animals. In both organs phase I and phase II drug metabolizing enzymes have been found to be increased along with decrease in GSH contents following TCE inhalation. Pulmonary as well as hepatic MFO's seem to be activated by inhaled TCE probably in an attempt for its rapid detoxification and reduced glutathione is used during its biotransformation.

Abstract
OBJECTIVE The pulmonary toxicity of a commercially available formulated preparation of Fenvalerate (Fen), a synthetic pyrethroid has been studied in rats following subchronic nose only inhalation exposure route. METHOD Adult male rats were exposed to Fen for 4 h/day, 5 days a week for 90 days by using Flow Past Dynamic Nose only Inhalation Chamber. RESULTS Fen exposed rats showed a significant increase in enzymatic activities of lactate dehydrogenase (LDH), acid phosphatase (ACP), alkaline phosphatase (ALP) and gamma-glutamyl transferase (gamma-GT) which are considered as biochemical indicators of pulmonary damage. The concomitant histopathological examination of Fen exposed rats' lung revealed inflammatory changes viz., influx of mononuclear cells admixed with a few giant cells in alveolar lumen, hypetrophied bronchiolar and alveolar epithelial lining cells and presence of edematous fluid in alveolar lumen alongwith congested parenchymatous blood vessels. CONCLUSION These results for the first time indicate the pulmonary toxic effects of a commonly used formulated Fen preparation by using rat model and nose only inhalation as the route of exposure.

Abstract
OBJECTIVE Trichlorethylene (TCE) is one of the most potent organic unsaturated solvents being used in dry cleaning, metal degreasing, thinner for paints varnishes and electroplating, etc. and has been reported to be a hepatoxicant through oral and dermal exposure. However, its inhalation toxicity data is very limited in the literature due to the fact that the exposure levels associated with these effects were usually not reported. Hence, inhalation toxicity study was carried out for hepatotoxic studies. METHODS Inhalation toxicity studies was carried out by exposing rats to TCE for 8, 12 and 24 weeks in a dynamically operated whole body inhalation chamber. Sham treated control rats were exposed to compressed air in the inhalation chamber for the same period. RESULTS Significant increase in liver weight (liver enlargement) appeArance of necrotic lesion with fatty changes and marked necrosis were observed after longer duration (12 and 24 weeks) of TCE exposure. The lysosomal rupture resulted in increased activity of acid and alkaline phosphatase alongwith reduced glutathione content and total increased sulfhydryl content in liver tissue. CONCLUSION TCE exposure. through inhalation route induces hepatotoxicity in terms of marked necrosis with fatty changes and by modulating the lysosomal enzymes.

Abstract
Trichloroethylene (TCE) is an organic solvent used in dry cleaning, metal degreasing, thinner for paints and varnishes, anesthetic agent, and so forth. Human beings are appreciably exposed to TCE vapours by inhalation route. The present study has been undertaken to investigate whether TCE inhalation may also bring about testicular toxic effects. Our results indicate that inhalation of TCE by male rats for 12 and 24 weeks brings about significant reduction in absolute testicular weight, and alters marker testicular enzymes activity associated with spermatogenesis and germ cell maturation, along with marked histopathological changes showing depletion of germs cells and spermatogenic arrest.
