In search for strategies aimed at preventing oxidative threat to female fertility, a possible role of sirtuins has emerged. Sirtuins (silent information regulator 2 (Sir2) proteins), NAD(+) dependent enzymes with deacetylase and/or mono-ADP-ribosyltransferase activity, are emerging as key antiaging molecules and regulators in many diseases. Recently, a crucial role for SIRT1 and SIRT3, the main components of sirtuin family, as sensors and guardians of the redox state in oocytes, granulosa cells, and early embryos has emerged. In this context, the aim of the present review is to summarize current knowledge from research papers on the role of sirtuins in female fertility with particular emphasis on the impairment of SIRT1 signalling with oocyte aging. On this basis, the authors wish to build up a framework to promote research on the possible role of sirtuins as targets for future strategies for female fertility preservation.

Background: Cancer treatments such as chemotherapy and radiotherapy often compromise fertility by damaging gonadal function, creating a critical need for fertility preservation options. Despite advancements in fertility preservation techniques, there is a significant lack of research focused on their application in Asian cancer patients and their utilisation remains underexplored in this population.
Aim: This study aims to evaluate the utilisation rates and outcomes of cryopreserved gametes in cancer patients who underwent fertility preservation before their cancer treatment.

Study Question: Is there an association between different mitochondrial DNA (mtDNA) genotypes and female infertility or ovarian response, and is the appearance of variants in the oocytes favored by medically assisted reproduction (MAR) techniques?
Summary Answer: Ovarian response was negatively associated with global non-synonymous protein-coding homoplasmic variants but positively associated with haplogroup K; the number of oocytes retrieved in a cycle correlates with the number of heteroplasmic variants in the oocytes, principally with variants located in the hypervariable (HV) region and rRNA loci, as well as non-synonymous protein-coding variants.
What Is Known Already: Several genes have been shown to be positively associated with infertility, and there is growing concern that MAR may facilitate the transmission of these harmful variants to offspring, thereby passing on infertility. The potential role of mtDNA variants in these two perspectives remains poorly understood.

Environmental radiation is one of the key causes of the increased prevalence of infertility among couples. This type of radiation can be ionizing or non-ionizing. While ionizing radiation is known to cause sterility in both males and females, the role of low-energy non-ionizing radiation is still debated.

Pancreatic islet transplantation is a crucial treatment for managing type 1 diabetes (T1D) in clinical settings. However, the limited availability of human cadaveric islet donors and the need for ongoing administration of immunosuppressive agents post-transplantation hinder the widespread use of this treatment. Stem cell-derived islet organoids have emerged as an effective alternative to primary human islets.

To analyze the coverage rate of adult herpes zoster (HZ) vaccine and the incidence of Adverse event following immunization (AEFI) in Jiangsu province, China. The vaccination information of HZ vaccine in people aged 50 years and above in Jiangsu province in 2023 and the AEFI information of HZ vaccine from 2020 to 2023 were collected through the Jiangsu Province vaccination management information system and China AEFI information management system, and the vaccination rate and AEFI incidence of HZ vaccine were analyzed. The overall vaccination rate among individuals aged 50 years and above was merely 0.
