w. for wild boar, 0.005-0.008 m2 kg-1 f.w. for roe deer, and 0.003-0.004 m2 kg-1 f.w. for red deer. The effective dose received by people who regularly consume local game meat ranged from less than 14.2 µSv y-1 to 134 µSv y-1, depending on the amount of differently contaminated game meat consumed annually. Even those for whom game is the only source of meat, consumption of wild boar along with local mushrooms and bilberries will, since 2012, not exceed the regulation limit of 137Cs at the level of 1 mSv y-1. By the best of our knowledge this is the first study regarding 137Cs activity in game and risk assessment from the most contaminated "post-Chernobyl" area in Poland.The increasing use of insecticides, promoted by the intensification of agriculture, has raised concerns about their influence on the decline of bee colonies, which play a fundamental role in pollination. Thus, it is fundamental to elucidate the effects of insecticides on bees. This study investigated the damage caused by a sublethal concentration of thiamethoxam - TMX (0.0227 ng/μL of feed) in the head and midgut of Africanized Apis mellifera, by analyzing the enzymatic biomarkers, oxidative stress, and occurrence of lipid peroxidation. The data showed that the insecticide increased acetylcholinesterase activity (AChE) and glutathione-S-transferase (GST), whereas carboxylesterase (CaE3) activity decreased in the heads. Our results indicate that the antioxidant enzymes were less active in the head because only glutathione peroxidase (GPX) showed alterations. In the midgut, there were no alkaline phosphatase (ALP) or superoxide dismutase (SOD) responses and a decrease in the activity of CaE was observed. Otherwise, there was an increase in GPX, and the TBARS (thiobarbituric acid reactive substances) assay also showed differences in the midgut. The TBARS (thiobarbituric acid reactive substances) assay also showed differences in the midgut. The results showed enzymes such as CaE3, GST, AChE, ALP, SOD, and GPX, as well as the TBARS assay, are useful biomarkers on bees. They may be used in combination as a promising tool for characterizing bee exposure to insecticides.Treatment of liver cancer has always been a challenge for clinicians and development of appropriate drug against hepatocellular carcinoma is the major focus for researchers working in the field. The synthesis of metal-based nanoparticles (NPs) by green method for pharmacological uses has attained considerable attention recently. In current study three different NPs (AgO2, CeO2, CuO2) were synthesized by using Trianthima portulacastrum and Chinopodium quinoa leaf extracts. These biogenic NPs were analyzed by High-tech. approaches including Scanning Electron Microscopy (SEM) with Energy Dispersive X-ray (EDX) spectroscope, SEM-EDS spot analysis, elemental mapping and X-ray diffraction (XRD). The anticancer potential of these nanoparticles was estimated using MTT assay, against hepatic cancer cell line (HepG2). SEM secondary electron images presented the nano size of prepared particles in agglomerated form with few porous forms. Average size of Ag-, Ce-, and CuNPs was observed 19-24 nm, 8-12 nm, 13-15 nm respectively. Elemental mapping and EDS-spot analysis ratifies the formation of AgNPs, CeNPs, and CuNPs. GNE-781 cost These NPs have shown good anticancer activity at different concentrations against HepG2 cell line. Further studies are however needed to identify the molecular mechanisms of these anticancer activities.Nickel (Ni), a widely distributed metal, is an important pollutant in the environment. Although kidney is a crucial target of Ni toxicity, information on autophagy and the potential mechanisms of Ni-induced renal toxicity are still poorly described. As we discovered, NiCl2 could induce renal damage including decrease in renal weight, renal histological alterations, and renal function injury. According to the obtained results, NiCl2 could obviously increase autophagy, which was characterized by increase of LC3 expression and decrease of p62 expression. Meanwhile, the result of ultrastructure observation showed increased autolysosomes numbers in the kidney of NiCl2-treated mice. In addition, NiCl2 increased mRNA and protein levels of autophagy flux proteins including Beclin1, Atg5, Atg12, Atg16L1, Atg7, and Atg3. Furthermore, NiCl2 induced autophagy through AMPK and PI3K/AKT/mTOR pathways which featured down-regulated expression levels of p-PI3K, p-AKT and p-mTOR and up-regulated expression levels of p-AMPK and p-ULK1. In summary, the above results indicate involvement of autophagy in renal injury induced by NiCl2, and NiCl2 induced autophagy via PI3K/AKT/mTOR and AMPK pathways in mouse kidney.Heavy metal (HM) stress in plants has received considerable global attention as it threatens sustainable growth in agriculture worldwide. Hence, desperate efforts have been undertaken for combating the effects of this stress in plants. Interestingly, the use of phytohormones in reducing the impact of HM toxicity has gained much momentum in the recent past. Phytohormones act as chemical messengers that improve the HM stress resistance in plants, thus allowing them to retain their growth and developmental plasticity. Their exogenous application as well as manipulation of endogenous levels through precise targeting of their biosynthesis/signaling components is a promising approach for providing a protective shield against HM stress in plants. However, for the successful use of phytohormones for field plants exposed to HM toxicity, in-depth knowledge of the key pathways regulated by them is of prime importance. Hence, the present review mainly summarizes the key conceptual developments on the involvement of phytohormones in the mitigation of HM stress in plants. The role of various genes, proteins, and signaling components involved in phytohormones associated HM stress tolerance and their modulation has also been discussed. Thus, this update will pave the way for improving HM stress tolerance in plants with the advent of phytohormones for sustainable agriculture growth in the future.Ammonia (NH3) emission is a common threat to farm animals. Selenium (Se) is known for its antioxidant property and can resist several stressors affecting farm animals. The aims of this study were (Ⅰ) to determine how excess NH3 exert nephrotoxic effects in pigs and (Ⅱ) to investigate whether selenomethionine has an alleviative effect on NH3 toxicity. Two diets supplemented with different doses of Se (0.22 mg/kg or 0.50 mg/kg) and two concentrations of NH3 ( less then 5 mg/m3 or 89.8 mg/m3) were used in a 2 × 2 factorial design trial for a period of 30 days. The results showed that NH3 exposure caused apoptosis and increased the number of apoptotic cells in pig kidneys. Further, the activities of antioxidant enzymes were decreased, and the transcriptional and translational levels of endoplasmic reticulum stress-related genes, Bcl-2 and Caspase family members were increased under NH3 exposure. In addition, Wnt/β-catenin signaling pathway was suppressed after NH3 treatment. Dietary supplement with selenomethionine appears to offer protection against NH3-induced kidney injury in pigs and the pathologic changes above were alleviated. Our findings provide additional insight into the mechanism of NH3 toxicity in pigs while elucidating the role of Se as a potential antidote against NH3 poisoning.Epidemiological studies have associated chronic exposure to arsenic (As) from drinking water with increased risk of hypertension. However, evidence of an association between As exposure from food and hypertension risks is sparse. To quantify the association between daily As intake from both food (rice, wheat and potatoes) and drinking water (Aswater) along with total exposure (Astotal) and hypertension risks in a study population in Bihar, India, we conducted an individual level cross-sectional analysis between 2017 and 2019 involving 150 participants. Arsenic intake variables and three indicators of hypertension risks (general hypertension, low-density lipoprotein (LDL) and high-density lipoprotein (HDL)) were derived, and any relationship was quantified using a series of crude and multivariable log-linear or logistic regression models. The prevalence of general hypertension was 40% for the studied population. The median level of HDL was 45 mg/dL while median value of LDL was 114 mg/dL. Apart from a marginally significant positive relationship between As intake from rice and the changes of LDL (p-value = 0.032), no significant positive association between As intake and hypertension risks could be ascertained. In fact, Astotal was found to be associated with lower risks of general hypertension and higher levels of HDL (p-value = 0.020 and 0.010 respectively) whilst general hypertension was marginally associated with lower Aswater (p-value = 0.043). Due to limitations regarding study design and residual confounding, all observed marginal associations should be treated with caution.Colorectal cancer (CRC), known as a frequently fatal disease, ranking as the third most common malignancy, is the second leading cause of cancer related mortality worldwide. Metastases are common in CRC patients which account for approximately 25% of the patients at diagnosis, 50% of patients during treatment which is associated closely with CRC mortality. Conventional therapies such as surgery, chemotherapy, and radiotherapy are standards of care for the treatment of CRC patients. However, primary tumor recurrence and secondary disease in patients receiving standard of care treatment modalities occur in 50% of patients so that new treatment modalities are needed. Immune checkpoint inhibition (ICI) has transformed the management of patients suffered from metastatic CRC (mCRC) with mismatch repair deficiency (dMMR) and microsatellite instability (MSI) -high (MSI-H) while manifests ineffectiveness in preserved mismatch repair (pMMR) or microsatellite stable (MSS) "cold" tumors which makes up the majority (95%) of mCRC. In this review, we mainly lay emphasis on the development of combinations in therapy strategies with ICIs with other immune based treatment approaches to increase the intra-tumoral immune response and render tumors 'immune-reactive', thereby increasing the efficacy of tumor immunotherapy.Since the beginning of vaccination programs against COVID-19 in different countries, several populations such as patients with specific immunological conditions have been considered as the priorities for immunization. In this regard, patients with autoimmune diseases or those receiving immunosuppressive agents and anti-cancer therapies, need special attention. However, no confirmed data is presently available regarding COVID-19 vaccines in these populations due to exclusion from the conducted clinical trials. Given the probable suppression or over-activation of the immune system in such patients, reaching a consensus for their vaccination is critical, besides gathering data and conducting trials, which could probably clarify this matter in the future. In this review, besides a brief on the available COVID-19 vaccines, considerations and available knowledge about administering similar vaccines in patients with cancer, hematopoietic stem cell transplantation, solid organ transplantation, multiple sclerosis (MS), inflammatory bowel disease (IBD), and rheumatologic and dermatologic autoimmune disorders are summarized to help in decision making.
