The current study was conducted to assess the effects of simultaneous usage with vitamin D3 and chromium picolinate (CrPic) supplementations on insulin resistance (HOMA-IR), fasting blood glucose (FBS), hemoglobin A1c (HbA1c), tumor necrosis factor- α (TNF-α), and lipid profile in type 2 diabetes
Aseptic loosening is the devastating long term complication of total hip arthroplasty and orthopedic implant debris has been shown to trigger an intense inflammatory reaction leading to resorption of the bone matrix. Inflammatory cytokines, such as tumor necrosis factor-α (TNFα), have been
Possible heavy-metal toxicity due to cadmium, chromium, nickel and lead in coxarthrosis and idiopathic necrosis of the head of the femur is reported on for the first time. Studies are made in the diseased head of the femur by means of ICP emission spectroscopy and atom absorption spectrophotometry.
OBJECTIVE
To report a case of acute tubular necrosis associated with the use of a chromium picolinate-containing dietary supplement.
METHODS
A 24-year-old white male who had been ingesting a dietary supplement (Arsenal X) for 2 weeks during his workout sessions developed acute renal failure.
The potential toxicity of metal ions in tissues surrounding metal-metal hip replacements is a cause for concern. Previous studies conducted in our laboratory demonstrated that Co(2+) and Cr(3+) induce TNF-alpha secretion in macrophages, as well as cell mortality. However, the degree of apoptosis and
Metal-on-metal (MOM) bearings offer extremely low wear and the avoidance of polyethylene but generate metallic wear particles. Although their total volume is dramatically smaller than polyethylene debris, these particles are in the nanometre size range and are many times more numerous. Metallic
OBJECTIVE
Impaired insulin sensitivity (SI) and β-cell function are the two main causes of type 2 diabetes (T2D) and are related to low-grade inflammation status. Trivalent chromium has shown to improve SI in our previous study. This might be due to the ability of decreasing interleukin-6 (IL-6) and
Hexavalent chromium is a toxin that penetrates the cell, triggering reactive oxygen species (ROS) production. Aronia melanocarpa, due to its proanthocyanidins, anthocyanins, and phenolic acid contents, is a valuable antioxidant. The aim was to observe the influence of hexavalent chromium Cr(VI) on
Currently available bioassays for most cytokines require several days and therefore must be performed under sterile conditions. In this report we describe a bioassay for tumor necrosis factor (TNF) and lymphotoxin (LT) that is extremely rapid and specific and does not require sterile conditions.
Heat stress adversely affects the productivity and immune status of dairy cows. The temperature-humidity index (THI) is commonly used to indicate the degree of heat stress on dairy cattle. We investigated the effects of different THI and Cr supplementation on the antioxidant capacity, the levels of
Citrullus plants were grown in refined sand with varying levels of chromium to determine their tolerance limit to excess chromium. The plants were maintained in control nutrient solution for 24 days and on the 25th day chromium as dichromate was added at 0.05, 0.1, 0.2, 0.3 and 0.4 mM. A control set
Fish constitute an excellent model to understand the mechanistic aspects of metal toxicity vis-à-vis oxidative stress in aquatic ecosystems. Hexavalent chromium (Cr (VI)), due to its redox potential can induce oxidative stress (OS) in fish and impair their health. In the present investigation, we
The leather industry is one of the major producers of wastewater, releasing large amounts of various chemicals into the environment. Chromium (Cr) is the most commonly used agent in the tanning industry. Accumulation in the animal body can adversely affect the functioning of animal tissues. The
