The development and use of human embryonic stem cells (hESCs) in regenerative medicine have been revolutionary, offering significant advancements treating various diseases. These pluripotent cells, derived from early embryos, are central to modern biomedical research. However, their application is mired ethical regulatory complexities related the embryos. This review utilized key databases such as ClinicalTrials.gov, EU Clinical Trials Register, PubMed, Google Scholar gather recent clinical...
This paper presents a 22 to 26.5 Gb/s optical receiver with an all-digital clock and data recovery (AD-CDR) fabricated in 65 nm CMOS process. The consists of front-end half-rate bang-bang circuit. achieves low power consumption by using inverter-based amplifiers realizes sufficient bandwidth applying several extension techniques. In addition, order minimize additional jitter at the front-end, not only magnitude but also group-delay responses are considered. AD-CDR employs LC quadrature...
Abstract Purpose To investigate whether the number of oocytes retrieved after controlled ovarian stimulation (COS) for fertility preservation (FP) can be predicted using serum anti-Müllerian hormone (AMH) levels in adolescent and young adult (AYA) women. Methods This is a retrospective cohort study large university-affiliated center. AYA women aged 11 to 25 years received COS gonadotropin-releasing (GnRH) antagonist protocols FP were enrolled. Those with canceled cycles or incomplete data...
A novel intensity-based temperature-independent strain sensor using a chirped grating is demonstrated. The longer reflection wavelength part of the fixed to glass tube and, hence, reflected power from decreases linearly with and independent temperature perturbation.
Objective The aim of this study was to compare the efficacy swim-up and density gradient centrifugation (DGC) for reducing amount sperm with fragmented DNA, sex chromosome aneuploidy, abnormal chromatin structure. Methods Semen samples were obtained from 18 healthy male partners who attended infertility clinics investigations processed DGC. percentages cells DNA measured by dispersion test, normal chromosomes assessed fluorescence in situ hybridization, structure identified toluidine blue...
The purpose of this study was to determine the effect vaginal progesterone for luteal phase support (LPS) on clinical pregnancy rate (CPR) in natural frozen embryo transfer (FET) cycles via a meta-analysis.We performed meta-analysis randomized controlled trials (RCTs) and retrospective studies that met our selection criteria. Four online databases (PubMed, Embase, Medline, Cochrane Library) were searched between January 2017 May 2017. Studies selected according predefined inclusion criteria...
Purpose: To elucidate the correlation between ovarian reserve and incidence of ectopic pregnancy (EP) following in vitro fertilization embryo transfer (IVF/ET) cycles. Materials Methods:In this observational study, 430 fresh IVF/ET cycles were examined from patient data two university hospital infertility clinics.All included patients positive for β-human chorionic gonadotropin (hCG) at 2 weeks after oocyte retrieval via controlled stimulation.For each cycle, information on age, duration...
To identify whether the BRCA mutations and hormone receptor status affect ovarian reserve stimulation outcomes in breast cancer patients undergoing fertility preservation.A total of 117 women diagnosed with who were referred to preservation clinics at Seoul National University Bundang Hospital between September 2012 July 2019 undergone for oocyte retrieval. Basal characteristics including age, BMI, basal AMH, FSH, such as number retrieved oocytes mature compared retrospectively.BRCA1...
Abstract Across the globe signage which conveys directives regarding appropriate behavior in public, such as ‘Do Not Enter’ signs, is made multilingual ways that other not. This paper examines two examples of multilingualism directive signs within Seoul, South Korea order to theorize what gives rise while remains monolingual.

Enhanced RhoA/Rho-kinase pathway plays anti-erectile role and is associated with reduced response to type 5 phosphodiesterase inhibitor (PDE5I) in diabetic animals. We tested whether adjunctive simvastatin conventional insulin treatment would restore PDE5I-induced as well basal erectile rat model of dysfunction. Forty 8-week-old male Sprague-Dawley rats were equally divided into four groups, (n=10) i.e. the group (D), age-matched control (C), (I) (S). Following 10weeks intraperitoneal...
Research on evacuation plans for reducing damages and casualties has been conducted to advise defenders against threats. However, despite the attention given research in past, emergency response management, designed neutralize hazards, undermined since planners frequently fail apprehend complexities contexts of situation. Therefore, this study considers a problem with unique characteristics duration emergency. An early stage is identified find optimal routing scheduling plan responders...
Objective The aim of this study was to investigate DNA fragmentation status in human spermatozoa according specific tail swelling patterns determined via hypo-osmotic test (HOST). Methods Frozen semen samples from 21 healthy donors were thawed and prepared by the swim-up technique for use intracytoplasmic sperm injection. treated 5 minutes as part HOST procedure then underwent chromatin dispersion using a Halosperm kit. (large halo, medium small no or degraded) pattern ("a"–"g") assessed at...
Background The level of vitamin D in follicular fluid (FF) according to the ovarian reserve has never been investigated, and effect FF on outcome assisted reproductive technology (ART) remains controversial. aim this study is evaluate association between levels baseline anti-Müllerian hormone (AMH) / ART outcomes. Methods Forty-seven patients who underwent controlled stimulation at fertility clinic an academic tertiary care center were enrolled for a prospective observational study. was...
Estrogen-dependent early stage endometrial cancer is relatively common in young women of reproductive age. The standard treatment hysterectomy and bilateral salpingo-oophorectomy (BSO), even well-differentiated patients. This surgical option results permanent loss fertility. There have been some reports live births using vitro fertilization after conservative management with high-dose progestin for the purpose fertility preservation. However, most were not recurrent cases pregnancy was...
