Mesenteric Fat

A technique is described for the rapid biopsy sampling of subcutaneous fat in cattle. The technique involves freezing and folding back a small area of skin to allow removal of the underlying fat. The advantages of this technique are that it is rapid, animals do not have to be placed under general or local anaesthetic, no suturing is required and there is little disturbance to the animal. No significant difference in pesticide level was found between subcutaneous, peri-renal, and mesenteric fat, but a significant positive correlation (r = 0.82) was found between combined DDE and DDT levels in biopsy and carcase subcutaneous samples. This indicated that the residues measured from biopsy samples in this experiment were a good indication to levels in the rest of the animal.

Background: All cirrhotic patients should be screened for oesophageal varices (OV) at the time of diagnosis. The development of a non-invasive method for the detection of OV is a vital issue in subjects with cirrhosis to decrease the need for invasive endoscopic procedures that can be costly. This work aimed to evaluate immature platelet fraction (IPF) as a non-invasive marker and predictor of OV. Methods: This cross-sectional study was carried out on 80 cirrhotic patients with esophageal varices diagnosed by upper endoscopy. They were divided into Group (1): 40 patients with cirrhosis with esophageal varices and Group (2): 40 patients with cirrhosis and without esophageal varices. All patients were subjected to the complete history taking, physical examination, routine laboratory investigations (Complete blood count, IPF, C-reactive protein, Liver and kidney function tests, Bone marrow aspiration for some cases, Ascetic sample analysis when applicable), Pelvic-Abdominal ultrasonography, Child Pugh score assessment, Upper GIT endoscopy. Results: There was a significant difference between the studied groups regarding IPF (p<0.001). At cutoff >12 IPF had (AUC= 0.993) with sensitivity of 97.5% and specificity of 97.5% for detection of esophageal varices. There was a significant negative correlation between IPF and platelets count (p- value < 0.001). There was a significant positive correlation between IPF and Child Pugh score (p- value <0.001). There was a highly significant positive correlation between IPF and CRP (p value <0.001). There was significant difference between the two groups as regards splenic longitudinal diameter (p<0.001). As regards platelet count, there was a significant difference between the two groups (p<0.001). It was significantly lower in Group 1. Conclusions: IPF is elevated in cirrhotic patients with naive esophageal varices than in cirrhotic patients without varices. IPF could be used as a noninvasive, easy to measure method for detection of the presence of esophageal varices at a cutoff level of >12.

Background/Aim. Parathyroid hyperplasia (PHP) is defined as an absolute increase in the mass of parenchymal cells of the parathyroid gland. PHP is classified as primary, secondary and tertiary. The enlargement of parathyroid glands (PG) is usually asymmetric, resulting in a ?dominant? gland. In order to confirm the diagnosis, at least two glands should be examined histologically. Subtotal parathyroidectomy, i.e. removal of the three PG and leaving a small remnant of the forth, is the treatment of choice. High percent of PHP recurrence imposes the need for preoperative high sensitivity localizing procedures. Parathyroid scintigraphy localizes about 60% of hyperplastic glands. The aim of this study was to correlate findings of subtraction parathyroid scintigraphy (SPS) with weight, pathohistologic finding and oxyphil cell (OC) content of PG in patients with primary, secondary and tertiary parathyroid hyperplasia. Methods. Twenty-seven patients with primary/secondary PHP underwent SPS before surgery. Scintigraphic results were graded from 1-5, in relation to the degree of uptake. SPS graded 3, 4 and 5 were considered positive. The number and weight of operated PG were evaluated macroscopically. Pathohistologic and cellular types were defined on standard stained hematoxylin-eosin slides. OC content was defined as a percent of OC and graded from 1 to 3: grade 1 < 10%, grade 2 ? 10% and grade 3 ? 20% of OC. Results. SPS localized dominant gland in all patients with sensitivity 100%, and 51 from 73 hyperplastic PG, with sensitivity per gland of 70%. PG weighed 0.1 g to 6.7 g (median 1 g). A significant positive correlation (p < 0.0001) was found between the SPS results and PG weight. A significant positive correlation was found between PG weight and OC content (p = 0.0002). An insignificant correlation was found between SPS and OC content. Thirty-eight PG had < 10% of OC, 32 PG had < 10% and 3 PG had ? 20% of OC. Four patients had diffuse PHP and 23 patients nodular PHP. There was no statistically significant difference in SPS results compared to hyperplasia type, and between OC content and hyperplasia type. A significant positive correlation (p = 0.05) was found between PG weight and hyperplasia type. Conclusion. A high positive correlation was found between SPS results and PG weight, PG weight and OC content and PG weight and hyperplasia type. Between SPS results and OC content, and between SPS results and hyperplasia type, an insignificant correlation was found. Our results showed that SPS is a reliable and very sensitive diagnostic tool in detecting abnormal PG in parathyroid hyperplasia, reaching 100% sensitivity in detecting a ?dominant gland? and sensitivity per localized gland of 70%. Causes that affect increased uptake of liposolubile Tc99m radiopharmaceuticals (RF) in the hyperfunctional PG tissue and conditions which prevent RF admission into the PG cells still remain to be accurately and precisely determined.

The thiamine content (by a short method) and the protein content of 754 samples of the 1946 wheat crop and 458 samples of the 1947 wheat crop were determined. In 1946 four varieties were tested m each of the four soil zones, while in 1947 three varieties were tested on the Brown and Dark Brown soils and four on the Black and Black-Gray Transition soils. A highly significant positive correlation between thiamine and protein content was found for the two crops. No significant differences between thiamine values of the Thatcher 1946 and 1947 crop were found. Similarly, an analysis of variance for thiamine content of Redman in the Black and Black-Gray Transition soil zones and Rescue in the Brown and Dark Brown soil zones, for the two crop years showed no significant difference. Of the four varieties, Thatcher, Rescue, Pelissier, and Stewart grown in the Brown and Dark Brown soil zones, Stewart was significantly higher in thiamine content. The greatest range in thiamine content was 2.73 μgm. per gm. for Thatcher in the Black-Gray Transition soil zone (mean 4.01 μgm. per gm.) to 9.57 μgm. per gm. for Stewart in the Brown soil zone (mean 6.18 μgm. per gm.). A highly significant difference was found for varieties grown in different zones for both years. The values decreased as the soil changed from brown to dark brown, to black and degraded black, and finally to gray.

Objective: To assess the changes occurring in both common carotid arteries (CCAs) intima-media thickness (IMT) in Yemeni chronic khat chewers using B-mode ultrasonography. Methods: This cross-sectional study was conducted among 195 participants (103 regular khat chewers and 92 non-khat chewers) conveniently selected at the Radiology Department of the University of Science and Technology Hospital (USTH) in Sana’a from August 2017 to August 2018. Data about gender, age, BMI, chewing khat and the period of chewing were collected from participants using a structured questionnaire. B-mode ultrasonography of bilateral CCAs was then performed to measure the IMT. Data were analyzed using suitable statistical tests, and P-values <0.05 were considered statistically significant. Results: The majority of participants with CCA-IMT were males (91.8%) and aged 27 years or younger (59.0%), with a mean age of 27.9 ± 6.8 years. Khat chewers constituted more than half of patients with CCA-IMT. There was no statistically significant difference in the mean values of RT CCA-IMT and LT CCA-IMT between khat chewers and non-khat chewers. The CCA-MIT was significantly higher among male khat chewers compared to male non-chewers (P = 0.004). However, there was no statistically significant difference between khat chewers and non-chewers with respect to the age of 20 years or older (P = 0.301) and BMI of 18.5 kg/m2 or higher (P = 0.888). Age showed a significant positive correlation with RT CCA-IMT (r = 0.380; P < 0.001) and LT CCA-IMT (r = 0.458; P < 0.001) in Khat chewers. In contrast, age showed a significant positive correlation with LT CCA-IMT only in non-khat chewers (r = 0.236; P = 0.024). On the other hand, BMI showed a significant positive correlation with LT CCA-IMT (r = 0.254; P = 0.010) among khat chewers, but no significant correlation was found in CCA-IMT of both sides among non-khat chewers. Among khat chewers, there was a significant positive correlation with RT CCA-IMT (r = 0.273; P = 0.005) and LT CCA-IMT(r = 0.194; P = 0.049). Conclusion: Khat chewing does not lead to a significant difference in CCA-IMT among Yemeni chewers compared to non-chewers. However, the period of chewing may slightly affect the CCA-IMT among khat chewers. Age has a significant positive correlation with CCA-IMT in khat chewers and LT CCA-MIT in non-khat chewers, which could help to determine the contribution of different predisposing factors to atherosclerosis. A significant positive correlation can be found between BMI and LT CCA-MIT among khat chewers. Keywords: Khat Chewing, Intima media thickness, Carotid, Yemen

Abstract Background The use of radiocontrast media has increased greatly from the past decades for diagnostic radiography and interventional procedures and it is estimated that approximately 60 million people in the world are used radiocontrast media each year. Objective The aim of this study was to evaluate the efficacy of atorvastatin (ATN) 80 mg in the prevention of CIN in patients undergoing angiography. Patients and Methods This study was a prospective, two‑arm, parallel group, controlled, clinical trial. This study has been performed on 100 Egyptian patients. Patients of either sex and aged between 21 and 65 years admitted for coronary angiography from January 2019 to June 2019, the patients had serum cretinine between 1 and 1.5 mg/dl or estimated glomerular filtration rate (eGFR &gt; 60 ml/min/1.73m2) and suffering from controlled DM or HTN. Results As regard to prevalence of contrast nephropathy, in our study we found that the total prevalence was 13%. We have concluded a great effect of diabetes on development of contrast nephropathy. We have concluded a great effect of hypertension on development of contrast nephropathy. There was a great effect of number of vessels affected on development of contrast nephropathy. As regard FBS there was no significant difference between the two groups. Also, there was a highly significant positive correlation between and study markers of acute kidney injury (72 h- Serum creat Delta Serum creat, 72 h- GFR and Delta GFR) and FBS. As regard Contrast media dose there was no significant difference between the two groups. Also, there was a highly significant positive correlation between and study markers of acute kidney injury (72 h- Serum creat Delta Serum creat, 72 h- GFR and Delta GFR) and contrast media dose. In our study there was a highly significant difference between the two groups as regard study markers of evidence of contrast nephropathy (72 h- Serum creat Delta Serum creat, 72 h- GFR and Delta GFR).Also, there was a great effect of on development of contrast nephropathy. In our study there was a highly significant difference between the two groups as regard study markers of evidence of contrast nephropathy (72 h- Serum creat Delta Serum creat, 72 h- GFR and Delta GFR).Also, there was a great effect of on development of contrast nephropathy. Conclusion There was a beneficial significant effect of statin on prevention of contrast nephropathy, also we concluded that age, hypertension, DM, dyslipidaemia, FBS, hemoglobin level, serum uric acid and dose of contrast media are major risk factors for developing contrast nephropathy.

The Relationship

The purpose of the present study was to investigate the relationship among EFL teacher’s identity style, religious identity, and identity commitment. The data was collected from 88 EFL teachers teaching at different English language learning institutes in Ilam province- Iran. Two questionnaires were used, including Dollinger’s (2001) Brief Religiosity Scale (BRS-6) and Berzonsky’s (1992) Identity Style Inventory, the revised version (ISI3). Results suggested that EFL teacher’s identity style and their commitment were positively correlated (r = 0.350). There was also a significant positive correlation between EFL teacher’s religious identity and their commitment (r = 0.312). A significant positive correlation was also found between EFL teacher’s identity style and religious identity (r = 0.367).  The results of one-way ANOVA indicated that there was a statistically significant difference in identity style scores, identity commitment scores, and religiosity scores for four groups. The results of independent t-test analysis indicated that there was no significant difference in identity style, identity commitment, and the religiosity scores of the two groups of participants. Finally, the implications and limitations of the study were also discussed.

A myocardial infarction (MI), often known as a heart attack, occurs when blood supply to a region of the heart is reduced or stopped, resulting in heart muscle damage. One of the elemental mechanisms responsible for the development of myocardial infarction is oxidative stress. The study aims to assess the Oxidative stress and Troponin I levels in patients with myocardial infarction (MI) and compare them with the level of these parameters in healthy controls. An attempt has been made to find if there is any correlation between oxidative stress and Troponin I levels in patients with myocardial infarction.The Cardiac marker Troponin I and the marker of oxidative stress malondialdehyde were estimated in 30 patients with myocardial infarction and 30 healthy individuals who acted as controls. A statistically significant difference was observed between Troponin I and MDA in patients with MI as compared with controls. A significant positive correlation was also observed between MDA and Troponin I levels. In our study there wasa significant positive correlation between oxidative stress and Troponin I. Further studies with a larger number of subjects will be needed to find if oxidative stress plays a role in the pathogenesis of myocardial infarction.
