Transcriptomic profiling with vascular tension analyses reveals molecular targets and phenotypes in preeclamptic placental vasculature.

Introduction: The placental vascular system plays an important role in the development of pregnancy hypertension in preeclampsia. The gene profiles of whole placental tissue (containing blood vessels and many other structural components) and pure vascular tissue should be very different. All previous reports using RNA-seq analysis in the placenta have tested its whole tissue or the villous part, and thus the gene profiles in the pure placental blood vessels are unknown.

Paternal preconception alcohol consumption increased Angiotensin II-mediated vasoconstriction in male offspring cerebral arteries via oxidative stress-AT1R pathway.

Alcohol consumption is popular worldwidely and closely associated with cardiovascular diseases. Influences of paternal preconception alcohol consumption on offspring cerebral arteries are largely unknown. Male rats were randomly given alcohol or water before being mated with alcohol-naive females to produce alcohol- and control-sired offspring.

U-Shaped Association Between Monocyte-Lymphocyte Ratio and Risk of Cardiac Conduction Block.

Purpose: Inflammation plays a critical role in the development of cardiac conduction block (CCB), which is associated with an increased risk of morbidity and mortality. The monocyte-lymphocyte ratio (MLR) acts as a novel inflammatory marker; however, its association with CCB has not yet been studied. This study aimed to investigate the association between MLR and CCB risk.

Prenatal Nicotine Exposure Raises Male Blood Pressure via FTO-Mediated NOX2/ROS Signaling.

Background: Cigarette smoking/nicotine exposure in pregnancy shows an increased risk of hypertension in offspring, but the mechanisms are unclear. This study tested the hypothesis that m6A RNA hypomethylation epigenetically regulates vascular NOX (NADPH oxidase) and reactive oxygen species production, contributing to the fetal programming of a hypertensive phenotype in nicotine-exposed offspring.

Methods: Pregnant rats were exposed to episodic chronic intermittent nicotine aerosol (CINA) or saline aerosol control from gestational day 4 to day 21, and experiments were performed in 6-month-old adult offspring.

In vitro fertilization with frozen embryo transfer increased histamine-mediated contractile sensitivity via PKCβ in human umbilical vein.

Objective: In vitro fertilization-embryo transfer (IVF-ET) technologies (especially frozen ET) have been widely used, which might affect maternal and fetal health. Information regarding influence of IVF-ET on the vasoconstriction of human umbilical vein (HUV) is limited. This study determined effects of frozen ET on histamine-mediated vascular responses in HUV and related mechanisms.

Common susceptibility variants of and are associated with poststroke depression in the Chinese population.

Background: Depression, one of the most frequent complications after stroke, increases the disease's burden and physical disability. Poststroke depression (PSD) is a multifactorial disease with genetic, environmental and biological factors involved in its occurrence. Genetic studies on PSD to date have mainly focused on the monoamine system and brain-derived neurotrophic factors.

Perinatal Fat-Diets Increased Angiotensin II-Mediated Ca through PKC-L-Type Calcium Channel Axis in Resistance Arteries via Gene Methylation.

Perinatal malnutrition affects vascular functions, and calcium is important in vascular regulations. It is unknown whether and how perinatal maternal high-fat diets (MHF)-mediated vascular dysfunction occurs via the angiotensin-PKC-L-type-calcium-channels (LTCC) axis. This study determined angiotensin II (AII) roles in the PKC-LTCC axis in controlling calcium influx in the arteries of offspring after perinatal MHF.

Melatonin in Reproductive Medicine: A Promising Therapeutic Target?

Melatonin, mainly released from the pineal gland, also produced in the reproductive organs and cells, plays important roles in rhythms of the sleep-wake cycle, retardation of ageing processes, and antioxidant/anti-inflammatory functions. As a key mediator in reproductive systems, melatonin is participated in the reproductive process via regulating gamete and embryo development and influences reproductive diseases and pregnancy outcomes. The underlying mechanisms include epigenetic and other regulations, which are interesting for exploring new targets in the prevention and treatment of reproductive diseases.

A Retrospective Cohort Study of Factors Influencing Lymph Node Metastasis in Patients With Early Gastric Papillary Adenocarcinoma.

Introduction: High risk of lymph node metastasis (LNM) in gastric papillary adenocarcinoma causes endoscopists to worry about the suitability of endoscopic resection for early gastric papillary adenocarcinoma (EPAC). We compared risk factors and attempted to establish a scoring system to stratify LNM risk in patients with EPAC.

Methods: A retrospective analysis was performed on 2,513 patients with early gastric carcinoma (EGC) who underwent radical resection in 4 tertiary hospitals in China.

Zanubrutinib Monotherapy for Naïve and Relapsed/Refractory Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma: A Pooled Analysis of Three Studies.

Introduction: Zanubrutinib is a highly selective irreversible inhibitor of Bruton tyrosine kinase which has shown significant activity in lymphoid malignancies in early phase studies. We report here the long-term follow-up outcomes of zanubrutinib in various lines of therapy in patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL).

Methods: This post hoc analysis pooled patients with treatment-naïve (TN) or relapsed/refractory (R/R) CLL/SLL receiving zanubrutinib monotherapy from three phase 1/2 studies (BGB-3111-1002, BGB-3111-AU-003, BGB-3111-205).

Introduction: Aquaporin 1 (AQP1) plays an important role in regulation of maternal-fetal fluid exchange and amniotic fluid volume. This present study aimed to determine the relationship between amniotic fluid index and placental AQP1 levels in terms of preeclampsia, and to reveal possible pathophysiological changes of AQP1 expression under preeclamptic conditions.

Methods: Placental tissues and medical records information were obtained from 389 preeclamptic and 447 uncomplicated pregnancies.

A bivalent live-attenuated vaccine candidate elicits protective immunity against human adenovirus types 4 and 7.

Human adenovirus types 4 (HAdV4) and 7 (HAdV7) often lead to severe respiratory diseases and occur epidemically in children, adults, immune deficiency patients, and other groups, leading to mild or severe symptoms and even death. However, no licensed adenovirus vaccine has been approved in the market for general use. E3 genes of adenovirus are generally considered nonessential for virulence and replication; however, a few studies have demonstrated that the products of these genes are also functional.

Prenatal hypoxia induced ETR activation and abnormal ROS signalling in pulmonary artery cells of rat offspring.

Pulmonary arterial hypertension is a progressive disorder characterized by remodeling and increased small pulmonary arteries resistance. Endothelin-1 (ET-1) was related to PAH and ET-1 receptors were up-regulated selectively in the lung when exposed to toxic factor hypoxia. However, the role of ET-1 signaling in the pathogenesis of prenatal hypoxia-induced pulmonary abnormalities remains to be elucidated.

Stage 1 hypertension defined by the 2017 ACC/AHA guidelines and neonatal outcomes: Systematic review and meta-analysis.

Background: In 2017, the American College of Cardiology/ American Heart Association (ACC/AHA) guidelines redefined the threshold of high blood pressure (BP) for non-pregnant adults. Several studies aimed to determine whether lowering these thresholds should be considered for pregnancies to prevent poor neonatal outcomes, but the results were inconclusive.

Methods: We perform a systematic review and meta-analysis to evaluate the association between BP groups defined by the 2017 ACC/AHA guidelines and pregnancy outcomes.

Prenatal High-Sucrose Diet Induced Vascular Dysfunction in Thoracic Artery of Fetal Offspring.

Scope: Maternal nutrition during pregnancy is related to intrauterine fetal development. The authors' previous work reports that prenatal high sucrose (HS) diet impaired micro-vascular functions in postnatal offspring. It is unclear whether/how prenatal HS causes vascular injury during fetal life.
