Inverse association between serum iron levels and Hashimoto's thyroiditis in United States females of reproductive age: analysis of the NHANES 2007-2012.

Purpose: Hashimoto's thyroiditis (HT) is a significant public health concern, particularly among females. While existing studies have explored the correlation between serum iron levels and HT, limited research has specifically focused on this association in reproductive-age females. Our study aims to investigate the relationship between serum iron and HT.

Modifications on histone tails in Parkinson's disease.

This study investigates the role of histone tail modifications in Parkinson's disease (PD), emphasizing the epigenetic regulation of genes associated with the disease. PD primarily manifests in individuals over 60, suggesting that PD-causal genes remain dormant until later in life, influenced by environmental factors and epigenetic modifications. Histone modifications such as methylation, acetylation, phosphorylation, and ubiquitylation play crucial roles in gene expression regulation by altering chromatin structure or interacting with gene regulatory regions.

Ring-Opening Polymerization of l-Lactide to Cyclic Poly(Lactide) by Zeolitic Imidazole Framework ZIF-8 Catalyst.

The catalytic activity of ZIF-8 in the ring-opening polymerization of l-lactide without solvents or cocatalysts is presented for the first time. Two different synthetic strategies have been applied for synthesizing ZIF-8, either under solvothermal condition or by spray-drying procedure. Their catalytic activities are found to be correlating with the presence of open active sites in ZIF-8 structure.

Methods: The essential oil of Ocimum basilicum var.

[Effect of hepatitis B virus C protein on function of natural killer cell in NK-92 cells].

Objective: To investigate the influence of hepatitis B virus C protein on the function of natural killer cell.

Methods: Recombinant eukaryotic expression plasmid pHBI-CMV-HBC was constructed and confirmed by double restrictive enzyme digestion and DNA sequencing analysis. Then the recombinant plasmid was transfected into NK-92 cells with lipofectamine encapsuled.

[Determination of aluminum in sediments by atomic absorption spectrophotometer without FIA spectrophotometric analysis].

To search for a new method of determining, we developed a new flow injection analyzer, applied to the atomic absorption spectrophotometer, relying on it without flame in place of visible spectrophotometer, and studied the appropriate condition for the determination of aluminum in sediments, thus built up a kind of new analytical test technique. Three peak and two valley absorption values (A1, A2, A3, A4 and A5) can be continuously obtained simultaneously that all can be used for quantitative analysis, then we discussed its theory and experiment technique. Based on the additivity of absorbance (A = A1+A2+A3+A4+ A5), the sensitivity of FIA is enhanced, and its precision and linear relation are also good, raising the efficiency of AAS.
