The trace element concentrations of Se, Rb, Zn, Fe, Co, Cs, Mg, Ca, F, Cu, Cr and Ag in serum and of Se, Rb, Zn, Fe, Co and Cs in red cells of Finnish alopecia patients were determined. In addition the Cu and Zn content in 24 h urine and Cu, Zn, Cd, Cr and Se concentrations in the hair of these patients were studied. No differences in element concentrations of the samples mentioned above as compared to those of the normal population could be found. In addition, there was no tendency of excesses or deficiences of elements analysed in the samples. Statistically significant difference was found between the copper content of serum in alopecia areata and alopecia universalis patients and also between the copper content of serum in alopecia areata plus alopecia totalis and alopecia universalis patients. The selenium concentration in serum samples of a few patients was low, but this is in agreement with the fact that the selenium content in the Finnish population is low due to the scanty content of selenium in food.

Proximal femoral fractures are particularly common in older adults, and cases requiring conversion to total hip arthroplasty may arise because of treatment failure or osteoarthritis. Fractures around the distal screw removal holes can be problematic. This study aimed to analyze the relationship between stem length and femoral stress distribution to determine the optimal stem length.

The use of hydrogen as fuel presents many safety challenges due to its flammability and explosive nature, combined with its lack of color, taste, and odor. The purpose of this paper is to present an electrochemical sensor that can achieve rapid and accurate detection of hydrogen leakage. This paper presents both the component elements of the sensor, like sensing material, sensing element, and signal conditioning, as well as the electronic protection and signaling module of the critical concentrations of H.

In this paper, a novel molecularly imprinted polymer membrane modified glassy carbon electrode for electrochemical sensors (MIP-OH-MWCNTs-GCE) for epinephrine (EP) was successfully prepared by a gel-sol method using an optimized functional monomer oligosilsesquioxane-AlO sol-ITO composite sol (ITO-POSS-AlO). Hydroxylated multi-walled carbon nanotubes (OH-MWCNTs) were introduced during the modification of the electrodes, and the electrochemical behavior of EP on the molecularly imprinted electrochemical sensors was probed by the differential pulse velocity (DPV) method. The experimental conditions were optimized.

Background: Children and adolescents with obesity have altered serum copper (Cu) and zinc (Zn) levels, which are associated with oxidative stress, inflammation, and health outcomes. The inclusion of cashew nuts in an adequate diet may provide health benefits and help improve the mineral status of individuals with obesity.
Objective: To evaluate the effects of cashew nut consumption on biomarkers of Cu and Zn status in adolescents with obesity.
