Polycystic ovary syndrome (PCOS) is the most common cause of female endocrine infertility. Insulin resistanсе is supposed to be one of the essential factors of this disease pathways. At the same time, the mechanisms of PCOS development in insulin-resistant patients have not been completely established. Leptin and Peroxisome Proliferator-Activated Receptor γ(PPARγ) are involved in carbohydrate metabolism and reproduction function regulation. It indicates that leptin and PPARγ possibly play a role in the pathways of PCOS. This article is a review of publications on this issue. The purpose of this review was to systematize the available information on the molecular mechanisms that determine the role of leptin and PPARγ in the development of PCOS. The literature search was carried out from 04/05/2020 to 05/17/2020 using the scientific literature databases: NCBI PubMed (foreign sources) and Cyberleninka (domestic sources). We analyzed publications for the period 1990-2020.The review presents the current understanding of the possible role of leptin and PPARγ in the regulation of endocrine, immune systems, and reproductive function, as well as in the development of PCOS. Currently, no studies cover the mechanisms of interaction between leptin and PPARγ in the pathways of this syndrome. The available studies indicating the individual contribution and association of leptin and PPARγ with PCOS are conflicting and have many limitations. Therefore, more studies of direct and indirect interaction of leptin and PPARγ, as well as their role in PCOS pathways, are needed.

Objective: This study aimed to evaluate bone remodeling in gingival crevicular fluid (GCF) during canine distalization in obese individuals and compare it to that in normal-weight individuals. Additionally, the orthodontic tooth movement rates of obese individuals were measured and compared with those of normal-weight individuals.
Methods: Thirty-six patients (18 obese and 18 normal-weight) aged 12-18 years who were candidates for maxillary first premolar extraction for Angle Class II malocclusion were included in the study.

Background: Knowledge of the complex interplay between gut microbiota and human health is gradually increasing as it has just recently been a field of such great interest.
Summary: Recent studies have reported that communities of microorganisms inhabiting the gut influence the immune system through cellular responses and shape many physiological and pathophysiological aspects of the body, including muscle and bone metabolism (formation and resorption). Specifically, the gut microbiota affects skeletal homeostasis through changes in host metabolism, the immune system, hormone secretion, and the gut-brain axis.

Type 2 diabetes mellitus (T2DM) and obesity are critical global health issues with rising incidence rates. Glucagon-like peptide-1 (GLP-1) analogues have emerged as effective treatments due to their ability to regulate blood glucose levels and gastric emptying through central nervous signals involving hypothalamic receptors, such as leptin. To address the short plasma half-life of native GLP-1, a C-16 fatty acid was conjugated to lysine in the GLP-1 analogue sequence to enhance its longevity.

A high-fat diet could lead to obesity, increasing colorectal cancer risk due to dyslipidemia and chronic inflammation, while Piper betle (PB) exhibits anti-tumor, anti-inflammation, and anti-oxidant benefits. This study aimed to determine whether PB possesses chemopreventive effects on high-fat diet (HFD)-induced and azoxymethane (AOM)-induced colon cancer. Male Sprague-Dawley rats receiving either a normal diet or HFD were divided into control, PB, AOM, and AOM+PB subgroups which were then sacrificed after 24 weeks.

Context: During pregnancy, women who experience certain pregnancy complications show elevations in biomarkers of inflammation and insulin resistance; however, few studies have examined these cardiometabolic biomarkers in the decade following pregnancy.
Objective: To examine the association between pregnancy complications and cardiometabolic biomarkers 9 years postpartum including: blood pressure, blood lipids, body fat percentage, insulin resistance (glucose, insulin, proinsulin, C-peptide, HOMA-IR, HbA1c, leptin, adiponectin) and inflammation (hs-C-reactive protein).
Methods: Using data from the Maternal-Infant Research on Environmental Chemicals (MIREC) cohort study (2008-2021) we determined 3 groups of pregnancy complications: 1) hypertensive disorders of pregnancy (HDP) (n=35); any pregnancy complication in the index pregnancy, defined as preterm birth, HDP, impaired glucose tolerance or gestational diabetes mellitus (GDM) (n=55); or self-reported recurrence of one of these pregnancy complications (n=19).
