The net atrioventricular compliance in mild to moderate hypertensive patients during the early left ventricle filling: A case series
...Show More Authors
BACKGROUND:

The compliance is considered one of the most important parameters which is defined as the change in volume with given change in pressure (dv/dp). It is varying inversely with both diastolic filling and modulus of chamber stiffness.

AIMS:

This study aimed to deduce the net atrioventricular compliance which is affected the trans mitral blood flow.

MATERIALS AND METHODS:

This study focuses on study group of 25 patients (15 males and ten females) with mild to moderate hypertension and mean age (49 ± 5.9) who were investigated for atrioventricular compliance and compared with 18 normal individuals (ten males and eight females) with a mean age of (44.9 ± 14.9) years old. The measurement of mitral valve area and the deceleration flow rate during ventricular early filling were taken from peak E wave to the minimum of the descending E wave. The atrioventricular (net) compliance was calculated according to the theoretical calculation Formula.

RESULTS:

When the atrioventricular compliance is measured during the early filling, a decrease in the net compliance of 50.27% in normal individuals was observed. The isovolumetric relaxation time was lower by 32.9% in normal individuals than in patients with mild to moderate hypertension.

CONCLUSION:

The increase in the atrioventricular net compliance for hypertensive patients is thought to be attributed to the compensatory mechanism of cardiac muscle before fibrosis can take place leading to a consequent increase in compliance measured during the early diastolic filling stage of the cardiac cycle.

The Shift towards Digital Education According to Vision 2030 in Light of Some Variables from the Perspective of Workers with Disabilities
...Show More Authors

The current study aimed to measure the attitudes of female teachers towards the use of digital learning and the degree of possessing their digital education skills. The study sample consisted of (180) workers with disabilities (mental disability، auditory impairment، visual disability، hyperactivity and distraction. To achieve the goals of the study, the transformation measure was used towards digital education for people with disabilities. The study reached the following results: the availability of digital learning skills among workers with disabilities. The study concluded with a series of recommendations including holding Training courses to keep up with the challenges of educational trends and modern technology in this area.

EFFECT OF ADDING A MIXTURE OF LION’S MANE HERICIUM ERINACEUS AND REISHI MUSHROOM GANODERMA LUCIDUM TO BROILER DIETS ON THE PRODUCTIVE PERFORMANCE
...Show More Authors

The study was conducted in the poultry field of the Department of Animal Production/ College of Agricultural Engineering Sciences/ University of Baghdad/ Abu Ghraib, for the period from 28/04/2022 to 08/06/2022 to demonstrate the effect of adding a mixture of Lion’s mane Hericium erinaceus and Reishi Mushroom Ganoderma lucidum to broiler's diets on productive performance, 120 one day old Ross 308 breed broiler chicks were used in the experiment, with (10 birds / replicate) with an average starting weight of 49.95 g. The experiment treatments were as follows:(T1) basic diet control treatment free of any addition. (T2) the basic diet with the addition of 0.5 g/kg fodder of Lion's Mane mushroom with 0.5 g/kg fodder of the Reishi Mus

Enhancing the therapeutic potential of curcumin: a novel nanoformulation for targeted anticancer therapy to colorectal cancer with reduced miR20a and miR21 expression
...Show More Authors
Abstract<p>Curcumin (Cur) possesses remarkable pharmacological properties, including cardioprotective, neuroprotective, antimicrobial, and anticancer activities. However, the utilization of Cur in pharmaceuticals faces constraints owing to its inadequate water solubility and limited bioavailability. To overcome these hurdles, there has been notable focus on exploring innovative formulations, with nanobiotechnology emerging as a promising avenue to enhance the therapeutic effectiveness of these complex compounds. We report a novel safe, effective method for improving the incorporation of anticancer curcumin to induce apoptosis by reducing the expression levels of miR20a and miR21. The established</p> ...

A Study on the Effect of Multistage Toolpath in Fabricating a Customized Cranial Implant in Incremental Sheet Metal Forming
...Show More Authors

Incremental sheet forming (ISF) process offers a high degree of flexibility in the manufacturing of different sheet parts, which makes it an ideal candidate for prototype parts as well as efficient at fabricating various customized products at low production costs compared to traditionally used processes. However, parts produced in this process exhibit notable geometrical inaccuracy and considerable thickness reduction. In this paper, the single point incremental sheet forming variant of the process has been implemented to manufacture a highly customized cranial implant starting from the computed tomography (CT) scan data of the patient's anatomy. A methodology, from the modeling to the realization of the implant, is presented and discus

Prey fear of a specialist predator in a tri-trophic food web can eliminate the superpredator
...Show More Authors

We propose an intraguild predation ecological system consisting of a tri-trophic food web with a fear response for the basal prey and a Lotka–Volterra functional response for predation by both a specialist predator (intraguild prey) and a generalist predator (intraguild predator), which we call the superpredator. We prove the positivity, existence, uniqueness, and boundedness of solutions, determine all equilibrium points, prove global stability, determine local bifurcations, and illustrate our results with numerical simulations. An unexpected outcome of the prey's fear of its specialist predator is the potential eradication of the superpredator.
