Objectives: Fat tissue is an important endocrine organ that produces a number of hormones and cytokines (leptin, adiponectin, resistin, plasminogen activator inhibitor-1, Tumour necrosis factor TNF α) with essential roles in regulation of many physiological functions.
Methods: We targeted implications of adipokines in ischemic stroke patients. Patients with acute stroke were examined (n=145) and the results were compared with the control group (n=68). We have examined potential associations between leptin, adiponectin and ghrelin, and different types of stroke and traditional risk factors.
Results: Significantly higher levels of leptin and lower levels of adiponectin and ghrelin were confirmed in the stroke group. The level of leptin in women with stroke was three-times higher than in men, and the leptin levels positively correlated with obesity in both sexes. Ghrelin levels correlated mildly with triglyceride levels, and were dominant in men with cardioembolic stroke. Adiponectin levels were not different between men and women with acute stroke, and correlated with atherothrombotic and lacunar stroke types in men.
Conclusions: Adipokines and ghrelin play an important role in ischemic stroke, but their function in stroke subtypes seems to be different and sex influenced. More research is required to confirm our results.

Introduction: Infants of diabetic mothers (IDMs) may exhibit decreased oral intake, requiring nasogastric feedings and prolonged hospitalization. The objective of this study was to explore whether saliva serves as an informative biofluid for detecting expression of hunger signaling and energy homeostasis modulator genes and to perform exploratory analyses examining expression profiles, body composition, and feeding outcomes in late preterm and term IDMs and infants born to mothers with normoglycemia during pregnancy.
Methods: In this prospective cohort pilot study, infants born at ≥ 35 weeks' gestation to mothers with gestational or type II diabetes (IDM cohort) and normoglycemic mothers (control cohort) were recruited.

Background: Given the potential role of brown adipose tissue (BAT) in stimulating energy expenditure, activating BAT can be an effective anti-obesity treatment. Here, we aimed to use adenoviruses to establish the effect of the inducible degrader of the low density lipoprotein receptor (IDOL) in the formation of BAT.
Methods: IDOL or green fluorescent protein was overexpressed by adenovirus and injected into the scapula of C57BL/6J mice and fed with high-fat diet for 12 weeks.

Background: Adipokines have been implicated in the pathogenesis of type 2 diabetes mellitus (T2DM) and related complications due to their roles in metabolic regulation and inflammation. However, the relationship between these adipokines and diabetic peripheral neuropathy (DPN) remains unclear.
Methods: A case-control study was performed with 198 patients with DPN and 205 T2DM patients without DPN from the Endocrinology Department at the Second Affiliated Hospital of Hainan Medical University.

Metabolic syndrome during menopause can lead to diabetes, cardiovascular problems, and increased mortality rates. Hormone replacement therapy is recommended to manage climacteric complications, but it has serious adverse effects. This study, therefore, investigated the potential of supplementing some minerals, vitamins, and natural products like boric acid, magnesium, vitamin D3, and extra virgin olive oil on metabolic status of menopausal ovariectomized rats.

Metabolic Syndrome (MetS) is a complex, multifactorial condition characterized by risk factors such as abdominal obesity, insulin resistance, dyslipidemia and hypertension, which significantly contribute to the development of cardiovascular disease (CVD), the leading cause of death worldwide. Early identification and effective monitoring of MetS is crucial for preventing serious cardiovascular complications. This article provides a comprehensive overview of various biomarkers associated with MetS, including lipid profile markers (triglyceride/high-density lipoprotein cholesterol (TG/HDL-C) ratio and apolipoprotein B/apolipoprotein A1 (ApoB/ApoA1) ratio), inflammatory markers (interleukin 6 (IL-6), tumor necrosis factor alpha (TNF-α), plasminogen activator inhibitor type 1 (PAI-1), C-reactive protein (CRP), leptin/adiponectin ratio, omentin and fetuin-A/adiponectin ratio), oxidative stress markers (lipid peroxides, protein and nucleic acid oxidation, gamma-glutamyl transferase (GGT), uric acid) and microRNAs (miRNAs) such as miR-15a-5p, miR5-17-5p and miR-24-3p.
