Different dermal cell types have been reported to differ in their sensitivity to nano-sized TiO2 . Kiss et al. exposed human keratinocytes (HaCaT), human dermal fibroblast cells, sebaceous gland cells (SZ95) and primary human melanocytes to 9 nm-sized TiO2 particles at concentrations from 0.15 to 15 μg/cm2 for up to 4 days. The particles were detected in the cytoplasm and perinuclear region in fibroblasts and melanocytes, but not in kerati-nocytes or sebaceous cells. The uptake was associated with an increase in the intracellular Ca2+ concentration. A dose- and time-dependent decrease in cell proliferation was evident in all cell types, whereas in fibroblasts an increase in cell death via apoptosis has also been observed. Anatase TiO2 in 20–100 nm-sized form has been shown to be cytotoxic in mouse L929 fibroblasts. The decrease in cell viability was associated with an increase in the production of ROS and the depletion of glutathione. The particles were internalized and detected within lysosomes. In human keratinocytes exposed for 24 h to non-illuminated, 7 nm-sized anatase TiO2, a cluster analysis of the gene expression revealed that genes involved in the “inflammatory response” and “cell adhesion”, but not those involved in “oxidative stress” and “apoptosis”, were up-regulated. The results suggest that non-illuminated TiO2 particles have no significant impact on ROS-associated oxidative damage, but affect the cell-matrix adhesion in keratinocytes in extracellular matrix remodelling. In human keratinocytes, Kocbek et al. investigated the adverse effects of 25 nm-sized anatase TiO2 (5 and 10 μg/ml) after 3 months of exposure and found no changes in the cell growth and morphology, mitochondrial function and cell cycle distribution. The only change was a larger number of nanotubular intracellular connections in TiO2-exposed cells compared to non-exposed cells. Although the authors proposed that this change may indicate a cellular transformation, the significance of this finding is not clear. On the other hand, Dunford et al. studied the genotoxicity of UV-irradiated TiO2 extracted from sunscreen lotions, and reported severe damage to plasmid and nuclear DNA in human fibroblasts. Manitol (antioxidant) prevented DNA damage, implying that the genotoxicity was mediated by ROS.

  • A charcoal basket is essentially a container designed to hold charcoal, ensuring even burning and easy management. Typically made of heavy-duty metal, it allows for airflow around the coals, promoting a consistent and controllable heat source. This is particularly important in barrel smokers, where maintaining the right temperature is vital for achieving the perfect smoke ring and desired flavor.


  • Furthermore, the convenience of these BBQs can lead to overuse, as users might not think twice before purchasing multiple units for a single outing. This consumer behavior exacerbates the issue of waste and underscores the need for more sustainable alternatives. Many disposable BBQs are designed for one-time use, which, while convenient, stands in stark contrast to the growing movement towards sustainability and responsible consumption.

  • One of the primary benefits of using sheet pan grates is the improvement in heat circulation. When food is placed directly on a sheet pan, it often cooks unevenly, leading to undesirable textures and flavors. By using a grate, air can circulate around the food, ensuring that it cooks uniformly from all angles. This principle is especially critical when roasting items like potatoes or chicken, where a crispy exterior paired with a tender interior is the goal. The even cooking achieved through the use of a grate results in perfectly crisped edges and moist centers, transforming a simple dish into a culinary masterpiece.

  • 2. Charcoal Grills For those who prefer a traditional smoky flavor, large charcoal grills are an excellent choice. They require a bit more effort to set up and manage the temperature but offer an authentic grilling experience that many enthusiasts cherish.


  • Setting up your charcoal pit grill requires just a few simple steps. First, you'll want to ensure your grill is clean and free of any leftover ash. Then, pile your charcoal in a mound or arrange it in a single layer, depending on whether you want to create direct or indirect heat zones. Lighting the charcoal can be accomplished using a chimney starter for an even and hassle-free ignite. Using natural fire starters or newspaper is advisable; avoid lighter fluid, as it can introduce unwanted flavors to the food.
