Uncontrolled degradation and collapse of stalled replication forks (RFs) are primary sources of genomic instability, yet the molecular mechanisms for protecting forks from degradation/collapse remain to be fully elaborated. Here, we show that polynucleotide kinase-phosphatase (PNKP) localizes at stalled forks and protects stalled forks from excessive degradation. The loss of PNKP results in nucleolytic degradation of nascent DNA at stalled RFs.

Who spontaneously became pregnant and completed the pregnancy successfully after peripartum hysterectomy of one uterus. The reason for the peripartum hysterectomy was a life-threatening hemorrhage with hemoperitoneum after cesarean delivery.

Here, we show that downregulation of the DNA repair protein, polynucleotide kinase/phosphatase (PNKP), in a variety of cell lines causes robust phosphorylation of STAT1, upregulation of interferon-stimulated genes and persistent accumulation of cytosolic DNA, all of which are indicators for the activation of the T1IFN response. Furthermore, this did not require damage induction by ionizing radiation.

Introduction: This was a single-center pilot study that sought to describe an innovative use of 4DryField® PH (premix) for preventing the recurrence of intrauterine adhesions (IUAs) after hysteroscopic adhesiolysis in patients with Asherman's syndrome (AS).
Material And Methods: Twenty-three patients with AS were enrolled and 20 were randomized (1:1 ratio) to intrauterine application of 4DryField® PH ( = 10) or Hyalobarrier gel ( = 10) in a single-blind manner. We evaluated IUAs (American Fertility Society [AFS] score) during initial hysteroscopy and second-look hysteroscopy one month later.
Background: Emerging evidence has shown racial and ethnic disparities in rates of harm for hospitalised children. Previous work has also demonstrated how highly heterogeneous approaches to collection of race and ethnicity data pose challenges to population-level analyses. This work aims to both create an approach to aggregating safety data from multiple hospitals by race and ethnicity and apply the approach to the examination of potential disparities in high-frequency harm conditions.

Methods And Results: Ectopic pregnancy is defined as implantation of an embryo outside the endometrial cavity, most often in the fallopian tube. This dia-gnosis is very common among young women.
Cellular adaptations to hypoxia promote resistance to ionizing radiation (IR). This presents a challenge for treatment of head and neck cancer (HNC) that relies heavily on radiotherapy. Standard radiosensitizers often fail to reach diffusion-restricted hypoxic cells, whereas nitroimidazoles (NIs) [such as iodoazomycin arabinofuranoside (IAZA) and fluoroazomycin arabinofuranoside (FAZA)] can preferentially accumulate in hypoxic tumours.

Conclusion: Patients with adenomyosis and fibroids may show a lower pregnancy rate and higher miscarriage rate than healthy individuals. However, there is no standard protocol for their optimal treatment, particularly in pregnancy-seeking or infertile women.
Early-onset neonatal sepsis contributes substantially to neonatal morbidity and mortality. Presenting signs and symptoms vary, and most causes are due to a limited number of common microbes. However, providers must be cognizant of unusual pathogens when treating early-onset sepsis (EOS).

Main Methods: several hydrazonoyl chlorides (HCs) were synthesized and human tumor cell line viability was determined using the MTT assay. Tumor development was assessed using Ehrlich ascites carcinoma (EAC)-bearing mice.
Racism- a system operating at the intrapersonal, interpersonal, institutional, and structural levels- is a serious threat to the health and wellbeing of children and adolescents. This narrative review highlights racism as a social determinant of health, and describes how racism breeds disparate pediatric health outcomes in infant health, asthma, Type 1 diabetes, mental health, and pediatric surgical conditions. Key examples include the association of residential racial segregation and the alarming infant mortality rate among Black infants as well as the role of redlining and discriminatory housing practices on asthma morbidity among Black children and adolescents.

The International Deep Endometriosis Analysis group consensus is the leading document for ultrasound assessment, while magnetic resonance imaging is guided by the European Society for Urogenital Radiology recommendations on technical protocol. In surgery, the revised American Society for Reproductive Medicine classification is the oldest system, ideally combined with newer classifications, such as Enzian or Endometriosis Fertility Index.

Introduction: This study was designed to evaluate the feasibility and effectiveness of hysteroscopy in the management of symptoms related to endometrial polyps and submucous leiomyomas in women using a levonorgestrel-releasing intrauterine system (LNG-IUS).
Material And Methods: Twenty-three LNG-IUS users presenting with endometrial polyps and/or submucous leiomyomas and irregular uterine bleeding were recruited for hysteroscopic examination and surgery. Intrauterine pathology was investigated and treated by hysteroscopic resection with the LNG-IUS , and the effect of the procedure on symptoms was evaluated after three to six months.
Background: Appropriate complementary feeding has the potential to prevent 6 percent of all under five deaths particularly in developing countries. However, infant and young child feeding practices in Ethiopia are suboptimal. Data on complementary feeding practices in Horro district are also lacking.

Methods: Consecutive patients with suspected endometriosis were prospectively enrolled in a tertiary center. They underwent an ultrasound and magnetic resonance imaging preoperatively, which was reported according to the International Deep Endometriosis Analysis (IDEA) group consensus.
Objectives: The primary aim was to investigate the diagnostic accuracy of transvaginal ultrasound (TVS) and magnetic resonance imaging (MRI) in the mapping of deep pelvic endometriosis (DE) in a diseased population. The secondary aim was to offer first insights into the clinical applicability of the new International Deep Endometriosis Analysis group (IDEA) consensus for sonographic evaluation, which was also adapted for MRI and surgical reporting in this study.
Methods: The study was a prospective observational cohort study.
Objective: To summarise the current knowledge and trends in the diagnosis of deep endometriosis.
Design: Review article.
Setting: Centre for diagnostics and treatment of endometriosis and Gynecologic Oncology Centre, Department of Obstetrics and Gynaecology, First Faculty of Medicine, Charles University and General University Hospital in Prague, Department of Gynaecology and Obstetrics, Burton Hospitals NHS, United Kingdom.
