Abstract
Heavy metal contamination of fish is a serious public health concern worldwide, including in Bangladesh. In this study, six commonly consumed fish species namely Hilsha (Tenualosa ilisha), Kachki (Corica soborna), Punti (Puntitus ticto), Taki (Channa punctatus), Meni (Nandus nandus), and Tengra (Mystus tengara) were analyzed for arsenic (As), cadmium (Cd), lead (Pb), zinc (Zn), copper (Cu), chromium (Cr), manganese (Mn), and nickel (Ni), by inductively coupled plasma mass spectrometry. The fish samples were collected from wholesale markets in Dhaka city, the main business hub of Bangladesh where the fishes converged from countrywide and are redistributed to the whole city. The metal concentration varied among the studied fish species. Hilsha, the national fish of Bangladesh, contained the highest As among the other fishes of this study, whereas Zn, Cd, Cu, Mn, and Ni were the highest in Kachki, and Pb and Cr were the highest in Tengra. The probable source of metal accumulation in the fish species may be the river or marine water that can be contaminated by industrial waste, pesticide, and/or fertilizer use in agriculture and/or commercial fish feeds. All analyzed fish species showed serious heavy metal pollution, having high average pollution load index (APLI) values (> 1). The estimated daily intake (EDI) values for the metals were lower than the maximum tolerable daily intake (MTDI). The hazard index (HI) for all the fish species was above 1 for adults, showing non-carcinogenic health risks. The target carcinogenic risk (TCR) values were below the acceptable limit (10-4) for most of the metals, indicating safe for consumption with respect to the risk of cancer.

Abstract
Background Interleukin-1 alpha (IL-1α) is a pro-inflammatory cytokine that can activate immune effector cells and trigger anti-tumor immune responses. However, dose-limiting toxicities including cytokine storm and hypotension has limited its use in the clinic as a cancer therapy. We propose that polymeric microparticle (MP)-based delivery of IL-1α will suppress the acute pro-inflammatory side effects by allowing for slow and controlled release of IL-1α systemically, while simultaneously triggering an anti-tumor immune response. Methods Polyanhydride copolymers composed of 1,6-bis-(p-carboxyphenoxy)-hexane:sebacic 20:80 (CPH:SA 20:80) was utilized to fabricate MPs. Recombinant IL-1α (rIL-1α) was encapsulated into CPH:SA 20:80 MPs (IL-1α-MPs) and the MPs were characterized by size, charge, loading efficiency, and in-vitro release and activity of IL-1α. IL-1α-MPs were injected intraperitonially into head and neck squamous cell carcinoma (HNSCC)-bearing C57Bl/6 mice and monitored for changes in weight, tumor growth, circulating cytokines/chemokines, hepatic and kidney enzymes, blood pressure, heart rate, and tumor-infiltrating immune cells. Results CPH:SA IL-1α-MPs demonstrated sustained release kinetics of IL-1α (100% protein released over 8-10 days) accompanied by minimal weight loss and systemic inflammation compared to rIL-1α-treated mice. Blood pressure measured by radiotelemetry in conscious mice demonstrates that rIL-1α-induced hypotension was prevented in IL-1α-MP-treated mice. Liver and kidney enzymes were within normal range for all control and cytokine-treated mice. Both rIL-1α and IL-1α-MP-treated mice showed similar delays in tumor growth and similar increases in tumor-infiltrating CD3+ T cells, macrophages, and dendritic cells. Conclusions CPH:SA-based IL-1α-MPs generated a slow and sustained systemic release of IL-1α resulting in reduced weight loss, systemic inflammation, and hypotension accompanied by an adequate anti-tumor immune response in HNSCC-tumor bearing mice. Therefore, MPs based on CPH:SA formulations may be promising as delivery vehicles for IL-1α to achieve safe, effective, and durable antitumor responses for HNSCC patients.

Abstract
Interleukin-1 alpha (IL-1α) is a cytokine involved in the acute phase immune response and its expression is upregulated in a variety of solid tumors including head and neck squamous cell carcinomas (HNSCCs). Tumor expression of IL-1α is associated with increased tumor aggressiveness in HNSCCs, but this has yet to be studied in the context of human papilloma virus (HPV) status. This study is aimed at determining differences in tumor expression and subcellular localization of IL-1α in HPV-positive (HPV+) and HPV-negative (HPV-) HNSCC tumors. Tissue microarrays (TMAs) containing HPV+ (n = 31) and HPV- (n = 47) primary and metastatic HNSCCs were analyzed for IL-1α expression using immunohistochemical (IHC) staining. HPV status was confirmed using p16 IHC staining and RNA in situ hybridization (RNA ISH). Differences in IL-1α protein expression and secretion in HPV+ and HPV- HNSCC cell lines were determined by western blot and ELISA respectively. Associations between tumor IL1A expression and survival outcomes were assessed in HPV+ and HPV- HNSCC patients from publicly available gene expression datasets. Tumor expression of IL-1α was significantly increased in HPV- tumors and cell lines (as detected by IHC and western blot respectively) compared to HPV+ tumors and cell lines. There was no difference in IL-1α release between HPV+ and HPV- cell lines. IL-1α was expressed in both nuclear and cytoplasmic compartments, with predominant expression in the nucleus. Gene expression of IL1A was significantly increased in HPV-tumors/cell lines compared to HPV+ tumors/cell lines. Lastly, increased IL1A gene expression was significantly associated with worse survival in HPV- tumors but not in HPV+ tumors. Overall IL-1α expression particularly in the nucleus may possess more prognostic significance in HPV- tumors rather than HPV+ tumors. This work warrants further investigation into the role of intracellular IL-1α ligand expression in HNSCCs and may have important implications in IL-1 pathway blockade as therapeutic strategy.

Abstract
Background: Rising tide of chronic nutrition related non-communicable diseases yoked with extant under nutrition problems makes it imperative to carry out scientific research for finding functional foods. Although the emergence of these diseases are believed to be related to a constellation of dietary, socio-economic and lifestyle related risk factors, central to the pathogenesis of these diseases (or disease states) are free radicals, oxidative stress, and inflammatory processes typically accompanied by pain. Therefore, functional whole foods with physiologically active antioxidants, anti-inflammatory, and analgesic compounds seem to be the most promising option to deal with the pathogenesis of existing and emerging chronic diseases burden of Bangladesh.Methods: Edible portions of 70 commonly consumed Bangladeshi foods – including one cereal, five legumes, fourteen vegetables, four tea varieties, five oil seeds, twenty spices, and twenty one fruits – were evaluated for total phenol content (TPC) by Folin-Ciocalteau assay. To evaluate functional potentiality, in vitro antioxidant capacity (AC) of selected food items were evaluated by DPPH radical scavenging assays, in vitro anti-inflammatory potential by observing the production of pro-inflammatory cytokine TNF-α using J774A.1 cells stimulated with lipopolysaccharide (LPS), in vivo anti-inflammatory potential by measuring carrageenan induced rat paw edema reduction and in vivo analgesic potential by acetic acid induced writhing test in mice. Results: Spices, oilseeds, and teas showed high concentration of TPC among the analysed foods while spices and teas exhibited notable AC. Green tea showed highest concentrations of TPC (2349 mg Gallic Acid Equivalent / g) and AC (2432 µmole Trolox Equivalent/g). Fourteen food items showed potential in vitro anti-inflammatory activity with confirmatory dose response effect shown by 8 items. In vivo, black sesame and yellow mustard expressed anti-inflammatory and analgesic effects in a dose dependent manner.Conclusion: This study found commonly consumed food items representing different food groups of Bangladesh to contain diverse range of polyphenols and antioxidant capacities. Of these, black sesame and yellow mustard demonstrated anti-inflammatory and analgesic potential in animal model. The findings of this study can be used to promote polyphenols rich foods through dietary guidelines and facilitate epidemiological research investigating diet-disease relationships.

Abstract
The presence of toxic heavy metals such as As, Cd, Pb, Cr, Mn, Ni, Cu, and Zn in nationally representative samples of highly consumed fruits and vegetables was determined by inductively coupled plasma mass spectrometry (ICP-MS). Their concentrations exceeded the maximum allowable concentration (MAC) set by FAO/WHO for Pb in mango and Cd in tomato among the analyzed fruits and vegetables. Pb content in mango was found to be six times higher than the safe limit at production level. Health risks associated with the intake of these metals were evaluated in terms of estimated daily intake (EDI), and carcinogenic and noncarcinogenic risks by target hazard quotient (THQ) and hazard index (HI). EDI values of all the metals were found to be below the maximum tolerable daily intake (MTDI). The THQs of all metals were <1, suggesting no health hazards for adult population. However, total THQs of Mn and Cu were >1 through consumption of all vegetables, indicating significant health risks. HI was found to be <1 (0.825) for consumption of fruits; however, it was >1 (3.727) for vegetable consumption, suggesting adverse health effects from vegetable consumption only. The total carcinogenic risk (CR) of As was below the threshold level (10(-6)) and 9.82E-05 for Pb, suggesting no potential CR from As consumption, but indicating the risk of Pb-induced carcinogenesis. The findings of this study reveal the health risks associated with the consumption of heavy metals through the intake of selected fruits and vegetables in adult population of Bangladesh.
