The Relationship between Thyroid Hormones and Insulin Resistance in Polycystic Ovary Syndrome Women.

Objective: This study aimed to investigate the changes in thyroid hormones in the serum of patients with polycystic ovary syndrome (PCOS) and their correlation with insulin resistance.

Design: This is a retrospective study.

Participants: 84 patients having insulin resistance and 76 patients without insulin resistance were included.

Optimizing the Effects of a Comprehensive Emergency Nursing Model on Rescued Patients with Acute Myocardial Infarction in the Cardiology Department.

Background: Acute myocardial infarction (AMI) requires timely and efficient intervention to mitigate adverse events and enhance patient prognosis. However, variations in emergency nursing protocols may impact treatment outcomes. Therefore, assessing the effectiveness of a comprehensive emergency nursing model, encompassing advanced assessment techniques and tailored interventions, is important for refining care strategies.

Preparation and properties of nanometer silk fibroin peptide/polyvinyl alcohol blend films for cell growth.

Nanometer silk fibroin peptide (Nano-SFP) was prepared from silkworm cocoons through the process of dissolution, dialysis and enzymolysis. For comparison, silk fibroin was decomposed with α-chymotrypsin, trypsin and neutrase, respectively. From the SEM and particle size analysis results, the Nano-SFP prepared by neutrase was found to be the most desirable at about 50-200 nm.

[Preparation of polyvinyl alcohol film inlaid with silk fibroin peptide nano-scale particles and evaluation of its function to promote cell growth].

Nano-scale particles of silk fibroin peptide (SFP) were prepared from discarded materials of cocoon or filature by dissolving and enzymolysis. Polyvinyl Alcohol films inlaid with silk fibroin peptide nano-scale particles (SFP in PVA) were prepared by blending nano-SFP and PVA in water according to different blending ratios. The films' characteristics and their promoting cell growth functions were investigated.
