CMV Human Cytomegalovirus, Clinical aspects and management of infection

masar almousawi — Tue, 14 Jun 2022 00:00:00 +0000

Cytomegalovirus is a virus DNA with an 83 percent global seroprevalence. It's cause of teratogenic congenital infection. As a result, it's a significant public-health issue. Congenital CMV (cCMV), the most public non-genetic cause of sensorineural hearing loss, is linked to maternal infection. CMV can also induce cerebral palsy and cognitive impairment. CMV is spread through contact with bodily fluids from a viral carrier. Viruses transmission is higher after primary infection, and it increases with gestational age. When infection develops before 20 weeks, however, severe fetal consequences are more likely. Past infection does not provide the mother immunity or provide protection to the fetus. On ultrasonography, CMV can cause cerebral or extracerebral abnormalities, as well as fetal development limitation and loss. Seroconversion in pregnancy (de novo appearance of virus-specific immunoglobulin G (IgG) in the serum of previously seronegative pregnant women) or the detection of specific immunoglobulin M (IgM) and IgG antibodies in association with low IgG avidity should be used to diagnose primary maternal CMV in pregnancy. The effective method for preventing viral infection is to provide pregnant women with hygiene advice and education. Vaccines, antiviral medicines, and immunoglobulins have all had their roles expanded throughout time.

Rasha Jwad, Abdul Jabbar Kadir — Tue, 14 Jun 2022 00:00:00 +0000

In this work, an aldehyde precursor has been prepared by four subsequent steps starting from L-ascorbic acid. This compound was reacted with different amines namely; phenyl hydrazine, aniline, p-toluidine, p-methoxyaniline, p-acetamidoaniline and 2-aminopyrimidene to afford six imine derivatives. Finally, the cycloaddition of Schiff bases to four separate acid anhydrides; maleic anhydride, 2,3-dichloromaleic anhydride, 3-nitrophthalic anhydride and phthalic anhydride produced 24 oxazepine derivatives. All synthesized compounds were characterized by FT-IR spectroscopy, ¹H NMR spectroscopy, micro-elemental analysis and TLC. The antibacterial activity of 1,3-oxazepines against S. aureus and E. coli were studies using disk diffusion method.

Baker A. Joda, Hiba Sadeq Alheloo — Tue, 14 Jun 2022 00:00:00 +0000

In recent years, cigarette smoking has become a major health issue, especially in terms of active and passive smoking exposure to chemicals released from the combustion of tobacco. The determination of trace elements in biological and environmental samples is very important since they play an important role in physiological processes of human and other living organisms. In this study, sixteen commercial cigarette brands were collected from Karbala, Iraq. The levels of Na, P, K, Fe, Cu, Zn, Sr, Cd, Sn, and Ba were determined in digested tobacco samples by using inductively coupled plasma atomic emission spectrometry (ICP-AES). The range of elemental levels for the 16 tobacco samples were Na (84 – 384 mg/L d.w.), P (1262 – 1687 mg/L d.w.), K (16878 - 30492 mg/L d.w.), Fe (166 - 349 mg/L d.w.), Cu (3 - 10 mg/L d.w.), Zn (18 - 35 mg/L d.w.), Sr (53 - 102 mg/L d.w.), Cd (0.24 – 2.03 mg/L d.w.), Sn (25 – 35 mg/L d.w.), Ba (7 – 16 mg/L d.w.). The levels of precision and accuracy for the ICP-MS instrument were confirmed by calculation of the relative standard deviation (%RSD) and percentage recoveries (%R) using ten replicate measurements of a "pooled" tobacco sample, and certified reference materials (CRMs). The results show a good range of precision (0.8 – 2.77 %RSD) and accuracy (90 -107 %R) was obtained.

Dry wear properties of Aluminum Alloy 6061 hardened with ceramic powders using diffusion method

RIDHA MAGEED — Thu, 16 Jun 2022 00:00:00 +0000

Surface hardening of metals is one of the efficient ways to give the metal new mechanical properties that are not present in the original metal.

In this paper, the effect of the type and size of the ceramic powder, temperature and time on the rate of diffusion of a number of ceramic powders across the surface of the AA 6061 was studied, and thus the amount of increase in hardness and wear resistance in the surface of this alloy. Several ceramic powders were used, such as sand, metakaolin, and iron oxide, with a granular size not exceeding 74 microns.

The results of the examination of the research samples showed an increase in the values of hardness and wear resistance compared to the original sample (AA 6061without addition).

The hardness and microscopy results also showed that temperature and time have an effect on diffusion rates. This relationship was not linear, as the aspect ratio of both the hardness and wear resistance values decreased with increasing temperature diffusion time.

The results also confirmed that the hardness and wear resistance of AA 6061 samples are proportional to the hardness value of the ceramic powder scattered in it.

Histopathological effect of Conium maculatum aqueous extract on liver in Rats

eman Almaliki — Tue, 14 Jun 2022 00:00:00 +0000

Conium maculatum is amongst the most poisonous species throughout higher plants. Humans and livestock are also both poisoned by Conium maculatum. Cosequently, Conium can be found growing alongside highways, purple-spotted, glabrous, and up to 3-meter-high , and branching. The leaves are decompounding pinnately like several edible and medicinal herbs. Coniine and -coniceine, two alkaloids found abundantly, are thought to be responsible for the plant's toxicity and teratogenicity, the relative ratio of distinct Conium alkaloids appears to be affected by several conditions such as temperature, hydration, period, and stage of growth. Conium includes piperidine alkaloids that are structurally similar to nicotine. They bind to nicotinic-type acetylcholine receptors and behave as agonists. The Rats used in this study were all from the Animal Resource Center at the University of Kerbala's College of Veterinary Medicine. In the current experiment, several doses of aqueous extract of conium were used at concentrations of 2, 5 and 10 mg/kg to get whatever effect these may have on the liver in Rats. 24 mature rats were divided into 4 groups, six rats for each concentration and control as well. The results showed massive changes on the liver tissues for all groups in comparison with control. However, all groups receiving Conium maculatum extract infusions at rates of 2 , 5 and 10 mg/kg of drinking aqueous revealed toxic changes in the liver in Rats, according to the findings of the research study
