USING DISCRIMINATE ANALYSIS WITH APPLIED ON BIRTHS OF PREMATURE BABY IN AL-SABEAN GENERAL HOSPITAL FOR MATERNITY AND CHILDHOOD IN THE CAPITAL SANA’A

2023-04-03T23:23:00+00:00

The current study aimed to employ the use of discriminant function analysis in classifying the new premature babies into living premature babies or dead premature babies. The study used the descriptive analytical method, the study consisted of a random sample of data on premature babies at the Statistics Center at Al-Sabean General Hospital for Maternity and Childhood for the years 2018-2020, its size reached (130) premature babies, of whom (98) lived and (32) died. The method of analyzing the discriminatory function used on the data in order to reach the classification of the new preterm babies into one of the two groups. The study reached to identify the most important independent variables in classifying the group of premature babies into one of the two groups. The first in importance is the smoking variable of the pregnant mother, followed by the variable of uterine age of the premature baby in weeks, then the variable of taking nutritional supplements during pregnancy, then the rest of the six approved variables in constructing the function of discrimination. The study also indicated the strength of the relationship between the variables included in the analysis, where the percentage of legal correlation of the discriminatory function was (0.85). The percentage of variance explained by the discriminant function through the value of the eta-square was (0.72), and it corresponds to an eigenvalue equal to (2.58). The results also indicated that the value of Wilks' Lambda amounted to (0.280), and the value of chi-squared amounted to (159.33), which is statistically significant at the level of significance (0.05). This confirms the ability of the discriminatory function to distinguish between the two groups of premature babies. Amounted classification accuracy between the two groups of premature babies (95.4%), which is a high percentage that confirms the accuracy of the classification.

THEORETICALLY PREDICTED DEVIATION IN PHYSICAL PROPERTIES OF GE-BI-S CHALCOGENIDE ALLOYS WITH COMPOSITIONAL VARIATIONS

2023-04-03T23:22:48+00:00

Chalcogenide glasses (ChGs) semiconductors have several useful properties, especially in their technical applications. The present work explains the compositional dependence of many physical properties of Ge_xBi₅S_95-x(x = 0, 10, 20, 30, 35 and 45 at. %). Increasing Ge content reduces the fraction of floppy modes, the lone pair electrons, the stoichiometric deviation, and the heat of atomization, while the average coordination number 〈r〉, constraints, density, and molar volume increased, indicating the alloys have moved from floppy to rigid mode. The average overall bond energy, electronegativity difference, band gap energy, and glass transition temperature were estimated by analyzing the bond energies and its distribution based on the bond ordered network model (CONM). It has been found that all these parameters increase with Ge ≤ 30 at. % and decrease with the further increase of Ge content. This behavior can be explained in terms of the network chemical percolation threshold proposed by Tanaka. This threshold represents a topological phase transition from a two-dimensional structure at r˂2.67 to a three-dimensional structure at r≥2.67. The incorporation of Ge into the glassy Bi-S system yields interesting physical properties such as threshold and phase transition, confirming this composition's suitability for optical storage media.

ASSOCIATION BETWEEN CHRONIC KHAT (CATHA EDULIS) CHEWING AND PLASMA LIPID PROFILE AMONG ADULT MALES FROM AL SHUAIB DISTRICT DHALA GOVERNURATE.YEMEN

2023-04-03T23:22:40+00:00

This study aims to investigate the association between chronic khat chewing (5 to 30 years duration) and dyslipidemia among healthy males in Al Shuaib District. One hundred participants from different villages agreed to complete the study with us. In this cross sectional study sample objects 230 males were selected randomly and divided according to ages and chewing khat duration, into four groups each (n= 20) and a control group of (n=20) non khat chewers. Data were obtained using a questionnaires and fasting blood sample collected and examined for lipid profile measurements including levels of total cholesterol TC, triglyceride TG, low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol (HDL-C).The mean levels of TC in groups D (179.5mg/dl) and E (180mg/dl) was higher significantly than control group subjects (156mg/dl). levels of HDL decreased in khat chewers; D and E groups (44.5mg/dl and 41mg/dl) respectively compared to the control group (46.4mg/dl). On the other hand, the average LDL increased in the D and E subject groups (103.4mg/dl) and (112.4mg/dl) respectively compared with control 93.8mg/dl. The level of TG was increased in all study groups A, B, D and E having statistical significance p < 0.05 compared with control C. There was a higher dyslipidemia among subjects of khat chewing groups than non khat chewers in relation to increase of mean years of khat chewing. There is a significant association between chronic khat chewing and dyslipidemia especially the decrease in HDL-C level was the main lipid variable followed by TG level. The imbalanced lipid profile might be due to genetic factor or social dietary habits, besides wide spread use of pesticides during cultivation of khat plant which have toxicity in area of study.

PREVALENCE OF ENTAMOEBA GINGIVALIS IN PATIENTS WITH GINGIVITIS AND PERIODONTITIS AND HEALTHY INDIVIDUALS AND ITS ASSOCIATED FACTORS

2023-04-03T23:22:37+00:00

The present study was carried out to determine the prevalence of Entamoeba gingivalis among 300 (156 males and 144 females) participants divided into three groups as follows: 100 patients with periodontitis (periodontitis group), 100 patients with gingivitis (gingivitis group), and 100 individuals with healthy gingiva (healthy control group), using wet mount technique with physiological saline and Giemsa stain. The overall prevalence of E. gingivalis was 18.3% and the highest prevalence of E. gingivalis was among periodontitis group (29%) followed by gingivitis group (18%), and healthy group (8%). The highest prevalence (23.7%) of E. gingivalis was found among the age group 40-49 years. Infection was highly significant in males than females (23.7% vs.12.5%). With regard to risk factors, the prevalence of E. gingivalis was common in non-tooth brush users, smokers, qat chewers, and diabetic patients and there were significant differences between tooth-brush users and non-tooth brush users, smokers and non-smokers, qat chewers and non-gat chewers, and between diabetic and non-diabetic patients and occurrence of E. gingivalis. We conclude that the higher prevalence of E. gingivalis in periodontal disease compared to healthy individuals may be an indicator of the potential role E. gingivalis in the pathogenesis of periodontal diseases.

The results of the current study showed significant complete inhibition (100%) of protoscolices viability in vitro treated with100 mg/ml of alcoholic extract of S. aromaticum after 3 hours of exposure. Also, 85% inhibition with concentration of 50 mg/ml after 3 hours, progressing to complete inhibition of protoscolices viability after 4 hours. With concentration of 1 mg /ml, 70 % inhibition was observed after 3 hours, progressing to 100% inhibition after 5 hours of exposure to S. aromaticum alcoholic extract. There were significant correlations between efficacy and concentration and between efficacy and exposure time.

NEW RECORDS OF BRACHYURAN CRABS SPECIES (CRUSTACEA-DECAPODA) IN GULF OF ADEN- YEMEN

2023-04-03T23:22:33+00:00

The information on the biodiversity of crustaceans, especially brachyuran crabs on the northern shore of the Gulf of Aden is even more limited and almost completely unknown. The coasts in the south of the Arabian Peninsula at the Gulf of Aden have not received much attention, with few studies in the field of marine biodiversity in general and brachyuran crabs in particular. There is a large gap in knowledge on the fauna of brachyuran crabs inhabiting the coastline in this region, so; this study aims to fill the gap in the data in this part of the Arabian Peninsula. In this study, 1750 brachyuran crab specimens were collected from 36 sites along the Yemeni coastal waters in the Gulf of Aden. These specimens were collected by hand, hand nets, snorkeling up to 2 m depth, SCUBA diving. Moreover, trawl nets were used up to 300 meters and small fish traps. All these specimens were transferred to ZSM for identification (by morphological characteristics and morphological characteristics of the gonopods) and putting together all information such as sex, measurements, locations, collection dates, habitats, and collectors of the specimens. This study recorded 163 brachyuran crabs’ species belonging to 17 super families, 28 families and 110 genera. Of the 163 species, 53 species represent the first record for Yemeni coastal waters at the Gulf of Aden. Moreover, 8 species were considered the first recorded in the marine waters of the Arabian Peninsula is given.

EVALUATION OF THE LEVELS OF HYDROQUINONE AND HEALTH RISK ASSESSMENT OF TOXIC METALS IN SKIN-WHITENING CREAMS

2023-04-03T23:22:31+00:00

This study assessed the level of toxic metals and hydroquinone in skin-lightening-creams commonly use in Ogun State, Nigeria. The pH of all the cream samples was determined and metals quantification was carried out using ICP-OES after acid digestion while that of hydroquinone was done using HPLC. The health risk of dermal exposure to heavy metals via the regular application was done by evaluating the carcinogenic and non-carcinogenic risk. The pH of all the samples are acidic and it follows this trend; Sample 3 > Sample 1 > Sample 4 > Sample 2. All the metals considered in this study were detected in all the analyzed samples except Cd, Co and Cr in sample 1, As, Ba and Pb in sample 2, Ag, As and Hg in sample 3 and Ba in sample 4. Highest levels of Al, Co, Pb and Zn were recorded in Sample 3 (Organic cream). Though the concentrations of most of the toxic metals (Al, Zn and Mn) are above the permissible levels, they pose no non-carcinogenic health risk based on the calculated HQ and HI. The carcinogenic risk of metals in the sampled creams were all within the acceptable limit except that of Cd. Hydroquinone was detected in all the four samples analyzed ranging between 2.58 and 4.17 % which exceeded the permissible limit by WHO. This finding show that long-term use of skin-whitening-creams may pose serious health hazards so, public should be continually enlightening on the hazardous health effects of the use.
