Background: The objective of this study was to evaluate the levels of Vascular Peroxidase 1 (VPO1), humanin, and MOTS-c in relation to miR-200c expression in untreated preeclamptic pregnancies, and to compare these findings with endoglin levels.

Methods And Results: In this study, blood samples were collected from preeclamptic patients presenting to the clinic prior to the initiation of treatment. The levels of endoglin, VPO1, humanin, and MOTS-c were measured using enzyme-linked immunosorbent assay (ELISA), while miR-200c expression was quantified using reverse transcription polymerase chain reaction (RT-PCR).

Article Synopsis
  • The study examines the role of soluble vascular endothelial cadherin (sVE-cadherin) in understanding preeclampsia, a condition characterized by endothelial dysfunction, by comparing serum levels in preeclamptic women and healthy controls.
  • A total of 240 pregnant women were involved, including those with early-onset and late-onset preeclampsia, with blood samples taken for analysis before labor, showing significantly higher sVE-cadherin levels in women with early-onset preeclampsia.
  • The findings suggest that sVE-cadherin levels correlate positively with blood pressure and inversely with gestational age, making it a key marker for identifying

Background And Aim: The study aimed to investigate the effectiveness of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and platelet values in predicting intrahepatic cholestasis of pregnancy (ICP) in the first trimester, together with the aspartate aminotransferase/platelet ratio index (APRI) score.

Materials And Methods: This study consisted of a patient group diagnosed with ICP (n=49) and a control group (n=62). Laboratory tests of both groups were analyzed retrospectively.

The aim of the study is to investigate the prevalence of state and trait probable clinical anxiety and their relationship with socio-demographic factors, attitude-behaviour, coping styles and social support level in high-risk pregnant women in the late period of COVID-19 pandemic. The pregnant women followed up in the gynaecological outpatient clinic were evaluated during their admissions. About 191 healthy pregnant women were included in the study.

Aim: This study was conducted to determine the fear of birth and coronavirus disease 2019 in pregnant women who applied to the high-risk pregnancy outpatient clinic during the pandemic and investigate whether there is a relationship between these fears.

Method: This study is a descriptive cross-sectional study using questionnaires. The Fear of COVID-19 Scale and Fear of Birth Scale for Pregnant Women were validated in Turkish in outpatient women with high-risk pregnancies.

Objective: This study aimed to evaluate the effectiveness of fetal left ventricular modified myocardial performance index in predicting adverse perinatal outcomes for intrahepatic cholestasis of pregnancy.

Methods: A cross-sectional study was conducted, including 51 women with intrahepatic cholestasis of pregnancy and 80 healthy controls. Using Doppler ultrasonography, E-wave, A-wave, isovolumetric contraction time, isovolumetric relaxation time, and ejection time were recorded and the left ventricular modified myocardial performance index was measured.

Article Synopsis
  • * Conducted with 140 participants aged 18-45 at a gynecology clinic, the research employed various surveys to gather data, focusing on anxiety, coping strategies, and social support-related attitudes.
  • * Results indicated high anxiety prevalence among participants, with significant predictors linked to concerns about COVID-19's impact on pregnancy and the use of ineffective coping methods like substance use, as opposed to more positive coping strategies among those without significant anxiety.

Objective: Ovarian torsion is a common cause of local ischemic damage, reduced follicular activity and infertility. This study aimed to investigate how well platelet-rich plasma (PRP) protects against experimental ischemic (I) and ischemia-reperfusion (I/R) injury in rat ovaries and its effect on in vitro fertilization (IVF) outcomes.

Method: Fifty-six adult female Sprague-Dawley albino rats were randomly assigned to six groups of eight animals each: Sham, Ischemia, I/R, Sham + PRP, I + PRP, and I/R + PRP.

Objective: To evaluate the serum vasostatin-1 levels in preeclamptic and non-preeclamptic pregnant women.

Materials And Methods: Thirty consecutive women with mild preeclampsia and sixty consecutive women with severe preeclampsia were compared with ninety gestational age-matched (±1 week) non-preeclamptic pregnant women with an appropriate-for-gestational-age (AGA) fetus.

Results: Mean serum vasostatin-1 was significantly higher in women with preeclampsia than gestational age-matched controls.

This study aimed to evaluate the effects of propofol and dexmedetomidine over different timescales on the IVF outcomes for transvaginal oocyte retrieval (TVOR). Twenty-four rats included in the study were divided into two main groups and three subgroups were subjected to the ovulation induction process. Group 1 was administered propofol (100 mg/kg i.

Introduction: Many people grieve in a resilient manner, often having a sense of equilibrium restored within six months. The most devastating type of loss is usually considered to be the death of the child. For such a loss, bereavement may take a period of distressing years with signs and symptoms that are related to grief.

Article Synopsis
  • - The study aimed to investigate the relationship between serum Neprilysin (NEP) levels and preeclampsia in women with mild and severe cases compared to healthy pregnancies.
  • - Results showed that women with both mild and severe preeclampsia had significantly higher NEP levels than those with uncomplicated pregnancies, with specific averages reported for both groups.
  • - The findings suggest a correlation between NEP levels and factors like blood pressure and kidney function, indicating potential avenues for research into NEP inhibitors as a treatment for preeclampsia.

: To evaluate the serum survivin level in preeclampsia.: Eighty-eight pregnancies complicated with preeclampsia and 88 gestational-age (GA)-matched uncomplicated pregnancies were evaluated.: Mean serum survivin was detected to be significantly decreased in the early- (EOPE) and late-onset (LOPE) preeclampsia subgroups than the GA-matched control-groups; and were comparable in EOPE- and LOPE-groups after correction for GA.

Catestatin can inhibit catecholamine release from chromaffin cells and adrenergic neurons. Catestatin can also have a strong vasodilator effect. This may be useful in understanding the pathophysiology of preeclampsia and its treatment.

Nasal vaccination is considered to be an effective and convenient way of increasing immune responses both systemically and locally. Although various nanovaccine carriers have been introduced as potential immune adjuvants, further improvements are still needed before they can be taken to clinical usage. Chitosan-based nanovaccine carriers are one of the most widely studiedadjuvants, owing to the abilityof chitosan toopen tight junctions between nasal epithelial cells and enhance particle uptake as well as its inherent immune activating role.

Mucosal vaccination stimulates both mucosal and systemic immunity. However, mucosal applications of vaccine antigens in their free form generally result in poor systemic immune responses and need adjuvantation. In this study, bovine serum albumin loaded, new hybridised poly(β-amino ester)-poly(d,l-lactide-co-glycolide) nanoparticles were prepared by double emulsion-solvent evaporation method, characterised and evaluated in vivo as nasal vaccine carriers.
