Introduction: A continuing challenge for malaria control is the ability of to develop resistance to antimalarial drugs. Members within the transcription factor family AP2 regulate the growth and development of the parasite, and are also thought to be involved in unclear aspects of drug resistance. Here we screened for single nucleotide polymorphisms (SNPs) within the AP2 family and identified 6 non-synonymous mutations within AP2-06B (PF3D7_0613800), with allele frequencies greater than 0.

Background: Monoamine oxidases (MAOs) is an enzyme that catalyzes the deamination of monoamines. The current research on this enzyme is focused on its role in neuropsychiatric, neurodevelopmental, and neurodegenerative diseases. Indeed, MAOs with two isoforms, namely, A and B, are located on the outer mitochondrial membrane and are widely distributed in the central nervous system and peripheral tissues.

The relationship among polycystic ovary syndrome (PCOS), endometrial cancer (EC), and glycometabolism remains unclear. We explored shared genes between PCOS and EC, using bioinformatics to unveil their pathogenic connection and influence on EC prognosis. Gene Expression Omnibus datasets GSE226146 (PCOS) and GSE196033 (EC) were used.

Objective: Various stem cell-loaded scaffolds have demonstrated promising endometrial regeneration and fertility restoration. This study aimed to evaluate the efficacy of stem cell-loaded scaffolds in treating uterine injury in animal models.

Methods: The PubMed, Embase, Scopus, and Web of Science databases were systematically searched.

Background: Intrauterine adhesion (IUA) results from serious complications of intrauterine surgery or infection and mostly remains incurable. Small extracellular vesicles (sEVs) derived from mesenchymal stem cells (MSCs) have emerged as a potential new approach for the treatment of IUA; however, their impact is not fully understood. Here, we performed a meta-analysis summarizing the effects of sEVs on IUA in preclinical rodent models.

Endometrial cancer (EC) is one of the most common gynecological cancers, and its risk factors include obesity and metabolic, genetic, and other factors. Recently, the circadian rhythm has also been shown to be associated with EC, as the severity of EC was found to be related to night work and rhythm disorders. Therefore, circadian rhythm disorders (CRDs) may be one of the metabolic diseases underlying EC.

Background: Infections with Plasmodium ovale are widely distributed but rarely investigated, and the resulting burden of disease has been underestimated. Plasmodium ovale curtisi Duffy binding protein domain region II (PocDBP-RII) is an essential ligand for reticulocyte recognition and host cell invasion by P. ovale curtisi.

Article Synopsis
  • Polycystic ovary syndrome (PCOS) is a complex hormonal disorder that leads to issues like infertility and imposes economic challenges on families and society.
  • Symptoms often include high levels of male hormones, irregular ovulation, and changes in ovarian structure, frequently related to obesity and insulin resistance.
  • Recent research highlights the role of Neuropeptide Y (NPY) in regulating both reproductive and metabolic functions, suggesting that targeting NPY and its receptors might provide new therapeutic options for improving the condition of women with PCOS.

Article Synopsis
  • Polycystic ovary syndrome (PCOS) is a reproductive disorder affecting women of reproductive age, characterized by symptoms like hormonal imbalances, irregular menstruation, and metabolic issues such as insulin resistance and obesity.
  • The exact causes of PCOS are still not well understood, but recent research suggests that changes in circadian rhythms may trigger the condition through oxidative stress and inflammation.
  • Exosomes, tiny vesicles that facilitate cell communication, may play a significant role in PCOS by transporting molecular signals, indicating that their interaction with circadian rhythms could be a key factor in the syndrome's development and potential treatment strategies.

Background: Premature ovarian insufficiency (POI) is the main cause of female infertility. Adipose-derived stem cells (ADSCs) are ideal candidates for the treatment of POI. However, some deficient biological characteristics of ADSCs limit their utility.

Objective: Intrauterine adhesions (IUAs) are a major cause of female infertility. Stem cells can be used to restore endometrial function owing to their regenerative abilities. We compared the safety and efficacy of autologous and allogeneic stem cell treatments in patients with recurrent IUA after conventional therapy based on a systematic review of the related literature.

Primary ovarian insufficiency (POI) is a rare gynecological condition. This disease causes menstrual disturbances, infertility, and various health problems. Historically, hormone replacement therapy is the first-line treatment for this disorder.

Intrauterine adhesion (IUA) is an endometrial fibrosis disease caused by repeated operations of the uterus and is a common cause of female infertility. In recent years, treatment using mesenchymal stem cells (MSCs) has been proposed by many researchers and is now widely used in clinics because of the low immunogenicity of MSCs. It is believed that allogeneic MSCs can be used to treat IUA because MSCs express only low levels of MHC class I molecules and no MHC class II or co-stimulatory molecules.

Aim: Endometrial cancer (EC) is a common type of malignant gynecological cancer. Small nucleolar RNA host gene 9 (SNHG9) has been discovered to serve a role in several types of cancer; however, the role of SNHG9 in EC remains unclear. The present study aimed to investigate the effects of lncRNA SNHG9 on cell proliferation and glycolysis in EC cells.

Background: The objective was to explore the therapeutic effect of autologous adipose-derived stem cells (ADSCs) combined with ShakeGel™3D transplantation to activate the BMP7-Smad5 signaling pathway to treat intrauterine adhesions (IUA).

Methods: Autologous ADSCs were isolated and then merged with ShakeGel™3D. The IUA model was established by mechanical injury.

Background And Aims: Thrombolytic therapy is widely used to treat acute ischemic stroke (AIS) patients. As intracerebral hemorrhage is a life-threatening complication of this therapy, monitoring the fibrinolytic and coagulation systems is imperative. However, existing studies on plasmin inhibitor complex (PIC) and thrombin-antithrombin III complex (TAT) mostly apply the enzyme-linked immunosorbent assay (ELISA) method.

Naringin is a promising anticancer bioflavonoid phytochemical, mainly extracted from citrus fruits. This study evaluates the antiproliferative effect and the cell death mechanism induced by naringin on cervical cancer (CC) cells. Our results demonstrated that naringin exerts significant inhibition in cell viability and exhibits IC50 value 745, 764, 793 µM against C33A, SiHa, and HeLa cells respectively.

Female infertility impacts the quality of life and well-being of affected individuals and couples. Female reproductive diseases, such as primary ovarian insufficiency, polycystic ovary syndrome, endometriosis, fallopian tube obstruction, and Asherman syndrome, can induce infertility. In recent years, translational medicine has developed rapidly, and clinical researchers are focusing on the treatment of female infertility using novel approaches.

Diabetic nephropathy (DN), which is characterized by mesangial cell proliferation, is a common complication observed in diabetic patients. The protective effects of quercetin for DN have been reported; however, the mechanism has yet to be determined. We aimed to identify the underlying mechanism for quercetin protection against DN.
