Tea infusions contain many valuable bioactive compounds and elements. The research is aimed at examining them in terms of nutritional value and determining the optimal conditions for their preparation. The study determined the content of Ca, Cu, Fe, K, Mg, Mn, Na, Zn, and Al in infusions of black tea, including bagged and loose leaf. An atomic absorption spectrometer was used for...
Fish intake may constitute a significant route by which humans are exposed to metals, especially people who depend on fish as a source of protein as Alexandrians. Therefore, this study aimed to investigate the metal contents in muscles in eight commonly consumed freshwater (Tilapia, Catfish, and Common Carp) and marine fish species (Emperors, Groupers, Mackerels, Silver Pomfret...
Wild-growing mushrooms (macromycetes, macrofungi) are capable of accumulating high amounts of trace elements, including noble metals. In a series of analytical experiments, this study focused on the problem of correct determination of Ag mass fractions in the biomass of Ag-accumulating mushrooms, Ag-hyperaccumulators in particular. A unique experimental setup enabled to compare...
The purpose of this study is to measure the effects of acrylamide (AA) on bone marrow and blood and the protective efficacy of boric acid (B) in rats. The animals were divided into five groups: control, B, low-dose B + AA, and high-dose B + AA. After the 15 th day of the experiment, their blood and bone marrow were harvested to be kept for hematological analyses. While white...
There is a clear relationship between osteoarthritis (OA) and micronutrients. Excessive accumulation of micronutrients may play a negative role in aggravating the symptoms of OA. This study aims to sort out the causal relationship between micronutrients (zinc, copper, magnesium, vitamins A, C, E, D, B6, and B12, folic acid, iron, carotene, selenium, calcium, and potassium) and OA...
Cadmium (Cd) is a dangerous heavy metal that causes toxicity in humans and animals. Various protective agents are being investigated to ameliorate the toxic effect of Cd. Lactic acid bacteria are promising as a protective agent because of their ability to remove heavy metals from contaminated products. The aim of this study was to evaluate the effects of Lactobacillus plantarum...
Dyslipidemia is an important public health issue. Copper may influence lipid metabolism, possibly via inflammation, but the mechanisms remain unclear. This study aimed to assess the association between urinary copper concentrations and blood lipids (total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides...
A vital trace element, zinc, is involved in several metabolic and enzymatic functions, such as antioxidant defense and ammonia detoxification. Zinc metabolism is disturbed by liver cirrhosis, especially when it is decompensated, contributing to systemic complications, including hepatic encephalopathy (HE). This study aimed to assess serum zinc levels in patients with...
This study aimed to determine the protective role of boric acid (BA) in high fructose (HF)-induced liver and kidney toxicity in a young rat model. High-fructose consumption causes serious damage to liver and kidney tissue in healthy individuals and contributes to the emergence of various metabolic diseases. Thirty-two healthy female Wistar albino rats (250–300 g weight and 3–4...
The study aims to investigate whether selenium (Se) has a protective role against testicular toxicity induced by 4-nonylphenol (4-NP) in rats and reduces oxidative damage. For this purpose, 30 adult male Sprague–Dawley rats (250–300 g/90 days old) were divided into five equal groups: control, sham control, Se, 4-NP, and 4-NP + Se. The trial lasted 48 days, with 4-NP administered...
Chronic fluorosis is often accompanied by neurological symptoms, leading to attention, memory and learning ability decline and causing tension, anxiety, depression, and other mental symptoms. In the present study, we analyzed the molecular mechanisms of SIRT1–BDNF regulation of PI3K–AKT, MAPK, and FOXO1A in F-treated BV2 cells. The cytotoxic effect of sodium fluoride (NaF) on BV2...
As teeth develop, their mineralised composition is a bio-recorder of diet, environment, and growth. High-resolution elemental mapping provides a tool to reveal records of life history within teeth. The relative concentrations of a range of trace elements change between in utero development, birth, and weaning in eutherian mammals. Marsupials, however, have a different mode of...
Several studies have reported associations between specific heavy metals and essential trace elements and acute myocardial infarction (AMI). However, there is limited understanding of the relationships between trace elements and AMI in real-life co-exposure scenarios, where multiple elements may interact simultaneously. This cross-sectional study measured serum levels of 56 trace...
Premature ovarian insufficiency (POI) is poorly understood, with causes identified in only 25% of cases. Emerging evidence suggests links between trace elements (TEs) and POI. This study is the first to compare concentrations of manganese (Mn), copper (Cu), zinc (Zn), selenium (Se), molybdenum (Mo), arsenic (As), cadmium (Cd), mercury (Hg), and lead (Pb) across urine, serum, and...
This study examined the possible defensive role of coenzyme Q10 (CQ10) against the impact of cadmium (Cd) and titanium dioxide nanoparticle (TNP) exposure on rat kidneys. Distilled water (1 mL/rat), corn oil (1 mL/rat), 10 mg CQ10/kg b.wt, 50 mg TNP/kg b.wt, 5 mg Cd/kg b.wt, TNP + Cd, or TNP + Cd + CQ10 was administered orally to seven groups of 70 male Sprague Dawley rats for 60...
Nickel has an impact on human health, especially in the context of the new energy industries. Nickel’s influence on glycemia remains controversial, and the effects and mechanisms of nickel on islet function still need further exploration. MIN6 cells were treated with different concentrations of nickel sulfate (NiSO4) (0, 75, 150, and 300 µg/mL) for different durations (0, 12, 24...
Male infertility is a complex and multifactorial clinical condition affecting a large population attributed to several factors, including perturbation in oxidative stress and the level of essential trace elements. Oxidative stress exerts multiple issues related to reproductive health, including male infertility, decreased sperm motility, sperm DNA damage, and an increased...
