Herein we report a facile approach for chitosan-heparin hydrogels with controlled release manner and their applications for intrauterine adhesion. The sol precursor was converted to gel at physiological temperature in 15 min. FTIR, SEM and swelling test were performed to characterize their compositions, morphologies and stability. In vitro releasing profiles was investigated in PBS solutions. Intrauterine injured rat model was established and treated with different methods. The results of H&E staining, Masson trichrome staining, western blots assay, immunohistochemical staining and immunofluorescence staining revealed that endogenous c-kit positive stem cells (HSCs) were recruited to the injury site and promoted the wound recovery. After 7 days' treatment, uterus treated with SDF-1α releasing hydrogel showed no difference with control group on endometrial thickness, glands number and fibrosis level. This work provides a possible method for intrauterine adhesion healing.

Mannose oligosaccharide (MOS) has been shown to promote animal growth, maintain intestinal health, and activate the intestinal immune system. However, the question of whether MOS can stimulate the immune system and alleviate acetylsalicylic acid (ASA)-induced gut damage remains unresolved. The purpose of this study was to investigate the impact of MOS pretreatment on the immunological and anti-inflammatory capabilities of rats with ASA-induced intestinal injury.

In this study, the relationship between plasma ghrelin levels and muscle atrophy was examined in an experimental diabetic rat model. 56 male Wistar albino rats, aged 8-10 weeks, were used in the study. The rats were divided into 8 groupsD1: one-week diabetes, C1: one-week control, D2: three-week diabetes, C2: three-week control, D3: six-week diabetes, C3: six-week control, D4: eight-week diabetes, C4: eight-week control.

Background: Long-term use of levodopa, a metabolic precursor of dopamine (DA) for alleviation of motor symptoms in Parkinson's disease (PD), can cause a serious side effect known as levodopa-induced dyskinesia (LID). With the development of LID, high-frequency gamma oscillations (~100 Hz) are registered in the motor cortex (MCx) in patients with PD and rats with experimental PD. Studying alterations in the activity within major components of motor networks during transition from levodopa-off state to dyskinesia can provide useful information about their contribution to the development of abnormal gamma oscillations and LID.

Background: Ischemic stroke (IS) is the leading cause of mortality worldwide. Herein, we aimed to identify novel biomarkers and explore the role of C-type lectin domain family 7 member A () in IS.
Methods: Differentially expressed genes (DEGs) were screened using the GSE106680, GSE97537, and GSE61616 datasets, and hub genes were identified through construction of protein-protein interaction networks.

Background: Polycystic ovary syndrome (PCOS) is a complex endocrine disorder with various contributing factors. Understanding the molecular mechanisms underlying PCOS is essential for developing effective treatments. This study aimed to identify hub genes and investigate potential molecular mechanisms associated with PCOS through a combination of bioinformatics analysis and Mendelian randomization (MR).
