Background: Leptadenia hastata (L. Hastata) is a plant used for various diseases in Nigeria. This study evaluated the protective effects of L. hastate on the haematological and biochemical alterations in adrenaline-induced hypertensive rats. Methods: Twenty-five rats were divided equally into five groups (A-E). Groups A-D were given 0.5 mg/kg adrenaline, groups A and B were treated with 100 an...

Background: With the development of technology, human beings are increasingly under the exposure of Radio Frequency Radiation (RFR) (due to wireless technologies, mobile phones, base stations etc). The aim was to investigate the possible effects of Radio Frequency Radiation (RFR) on blood, aorta and heart tissue in hypertensive and non-hypertensive rats with various parameters. Materials and Me...

BACKGROUND AND AIM: Hypertensive disorders in pregnancy are a leading cause of maternal and perinatal mortality. We evaluate the effects ambient temperature on risk hypertensive throughout pregnancy. METHODS: used birth register data for all singleton births (22-43 weeks’ gestation) recorded at tertiary-level hospital Johannesburg, South Africa, between July 2017-June 2018. Time-to-event analys...

To evaluate the risk of preterm labor and hypertensive disorders in pediatric pregnancies with without type 1 diabetes to changes frequency delivery admissions complicated by these conditions from 2006 2019. We used national Kids’ Inpatient Database identify (≤ 20 years old) 2006, 2009, 2012, 2016, ICD-9 ICD-10 codes (e.g. pre-eclampsia), pre-term labor. descriptive statistics logistic regressi...

INTRODUCTION This article is part of the Focus Theme of Methods of Information in Medicine on "Biosignal Interpretation: Advanced Methods for Studying Cardiovascular and Respiratory Systems". BACKGROUND Hypertensive pregnancy disorders affect 6 - 8 percent of all pregnancies and can result in severe complications for both the mother and the fetus. OBJECTIVES The aim of this study was to imp...

INTRODUCTION A recent study at the Maroua Provincial Hospital revealed that hypertension in pregnancy was the first cause of maternal death, representing 17.5% of the 63 maternal deaths recorded between 2003 and 2005. Knowing little about the causes, this study was to identify the possible risk factors for hypertensive disorders in pregnancy. METHODS This case-control study was-done at the Ma...

introduction: different vasoactive factors can modulate cardiovascular adaptation to hemorrhagic shock including nitric oxide (no). in this study we investigated the effect of  the no synthase inhibitor for treatment of  decompensated hemorrhagic shock in normotensive and hypertensive rats. methods: twenty‑four male wistar rats were divided into two groups: the normotensive and hypertensive gro...

Hypertensive disorder can cause cardiac deformities. Elastic characteristic parameters, like Young's modulus of elasticity (E) derived from a traditional cylindrical model, increase significantly with aging. However, the geometric and component changes of aging hearts because of chronic hypertension remain unknown. To better describe the effects, we propose an elliptical elastic and mathematica...

Ischemic acute renal failure (ARF) is a highly complex disorder involving renal vasoconstriction, filtration failure, tubular obstruction, tubular backleak and generation of reactive oxygen species. Due to this complexity, the aim of our study was to explore effects of Angiotensin II type 1 receptor (AT1R) blockade on kidney structure and function, as well as oxidative stress in spontaneously h...

Autonomic dysreflexia (AD) is a serious cardiovascular disorder in patients with spinal cord injury (SCI). The primary underlying cause of AD is loss of supraspinal control over sympathetic preganglionic neurons (SPNs) caudal to the injury, which renders the SPNs hyper-responsive to stimulation. Central maladaptive plasticity, including C-fiber sprouting and propriospinal fiber proliferation ex...
