Background: To evaluate the efficacy of speckle tracking echocardiography (STE) in detecting the existence, degree, and intensity of coronary artery affection in patients with suspected coronary artery disease (CAD). This study aimed to Investigate the ability of STE to identify the existence, size, and intensity of coronary artery affection in individuals with a suspected diagnosis of CAD. Methods: This cross-sectional study enrolled 200 candidates with suspected COD. Patients underwent STE and coronary angiography. Global longitudinal peak systolic strain(GLPSS) was measured and linked with coronary angiography findings for every subject. Results : ROC analysis was done for GLPSS in predicting single-vessel affection. It revealed a significant AUC of 0.713, with confidence interval of 95 percent ranging from 0.555-0.871 (P = 0.013). The best cutoff was ≤-18, at which specificity and sensitivity were 53.8 and 83 percent. ROC analysis was done for GLPSS in predicting multi-vessel affection. It revealed a significant AUC of 0.908 (P < 0.001). The best cutoff was ≤ - 11, at which specificity and sensitivity were 89.6 percent and 87.7 percent. Conclusion: Two-dimensional speckle tracking echocardiography predicts the existence, size, and degree of CAD with high sensitivity and specificity.

Background: Oxidative stress has been linked to chronic telogen effluvium (CTE). In a physiological sense, free radicals are eliminated by thiols, which are powerful and stable antioxidants. When oxidative stress is present, thiols are the body's go-to antioxidant. The purpose of this study is to compare serum total thiol, thiol-disulphide, and disulphide levels in female CTE patients to those of healthy controls. Topics and Approaches: Sixty people with CTE and twenty age-and sex-matched healthy volunteers served as the case and control groups, respectively, in this case-control research. From May 2020 to December 2021, they were scouted from the outpatient clinic of the Dermatology, Venereology, and Andrology Department at Benha University Hospitals. Results: There was no statistically significant difference in age or body mass index between the patients and the controls. In patients, total thiol levels were considerably lower than in controls. Patients had considerably lower levels of thiol-disulphide compared to healthy controls. Patients had considerably lower levels of disulphide compared to controls. The pathophysiology of TE is intimately linked to oxidative stress, we conclude. The development and prevention of oxidative stress are both influenced by the thiol-disulfide equilibrium. TE upsets this delicate equilibrium.

Background: The use of ultrasound has gained significant significance as a diagnostic method for pediatric gastrointestinal emergencies. The primary goal of this research was to evaluate the role of ultrasound in diagnosing non-traumatic gastrointestinal emergencies in children. Methods: This observational study included 100 pediatric patients, both sexes, aged 0-16 years old, who presented at the emergency department at Benha University Hospital with acute abdominal pain and were directed to abdominal ultrasound in the Radiology Department between July 2022 and December 2022. All patients were subjected to detailed history taking, full clinical examinations, routine laboratory investigations and Radiological investigations including abdominal-pelvic ultrasound and CT abdomen if needed. Results: the age ranged from 3 to 16 years with a mean ± SD of 9.8 ± 4.34 years. 43 (43%) patients had Rt lower ¼ pain, 95 (95%) patients had abdominal pain, 37 (37%) patients had ileus, 41 (41%) patients had diarrhea, 17 (17%) patients had hematochezia, 63 (63%) patients had vomiting, 29 (29%) patients had fever and 44 (44%) patients had worse general conditions. Free intra-abdominal fluid represented 10 (10%) patients, portal vein gas represented 6 (6%) patients, loculated Rt lower ¼ mass represented 4 (4%) patients, abscess represented 2 (2%) patients, fluid-filled, uncompressible, blind-ending tubular structure represented 26 (26%) patients, distended, fluid-filled bowel loops represented 30 (30%) patients, pseudo kidney appearance represented 8 (8%) patients, doughnut sign represented 17 (17%) patients, target sign represented 40 (40%) patients, enlarged mesenteric lymph nodes represented 33 (33%) patients. Conclusions: Ultrasonography (US) is a key imaging tool for the evaluation of acute abdominal pain, especially in young patients, for whom a satisfactory examination is occasionally impossible.

One of the most dangerous heart problems, ST-segment elevation myocardial infarction (STEMI) is linked to a wide range of potentially fatal consequences (cardiac and non-cardiac). Renal hypoperfusion and increased renal vascular resistance leading to acute kidney damage are potential outcomes of a STEMI episode characterised by low cardiac output and/or raised right ventricular sided pressure (AKI). The kidney damage caused by AKI may be temporary and resolve on their own, or it can be persistent and lead to the patient developing chronic cardio-renal syndrome (CRS), which has both immediate and long-term consequences. Renal impairment has been linked to poor cardiovascular outcomes, particularly heart failure, suggesting that monitoring renal function should be one of the primary targets of cardiac monitoring programmes.

Urinary bladder cancer is the second most prevalent kind of cancer affecting the urinary tract. Magnetic resonance imaging (MRI) is a useful imaging modality for the radiological examination of the urinary bladder and the prostate gland because of its high tissue contrast, multiplanar imaging capabilities, and the potential of tissue characterisation. The purpose of this research was to examine the relationship between the apparent diffusion coefficient (ADC) and the histologic grade of bladder cancer and to assess the use of DW-MRI as a staging tool for this disease. Thirty individuals with bladder mass were included in this trial. It was discovered that DWI has a higher overall accuracy (stage by stage) than T2WI and post contrast image (83.3% vs. 56.7% and 42.9%, respectively). In low grade tumours, the mean ADC value is high, whereas in high grade tumours it is low, with a cut off value of 0.83 mm2/s x10-3. Our research led us to the conclusion that DW-MRI is a reliable and secure tool for detecting and locally staging urinary bladder cancer. The histological grade of a tumour may be predicted using the ADC value as well. As a result, DWI may become a standard procedure for imaging malignancies in the urinary bladder.

Soil contamination with Cs possesses a serious environmental threat; and therefore, its remediation is an obligation to ensure environmental safety. The current study aims at evaluating the efficiency of using either EDTA-Na or DTPA as chelating agents for removal of Cs from contaminated soils. Three soils (a clayey oneand two sandy loam soils differing in the organic matter and CaCO 3 contents) were selected to attain this aim.Samples of the soils under study were artificially contaminated with CsCl at three levels i.e. 50, 100, and 200 mg Cs kg -1 . These samples were subjected to sequential extraction pre- and post- leaching to find out Cs redistribution among the different soil fractions after soil washing. The implications of soil washing with the investigated chelating agents on decreasing the risk assessment hazards associated with Cs hazards are discussed in this study. Key results indicated that DTPA was more efficient in removal of Cs from the contaminated soils than the EDTA-Nadidand both decreased considerably soil Cs, particularly from those which are considered the mobile fractions (water soluble and exchangeable fractions) beside of the carbonate bound fractions. Accordingly, the calculated risk assessment code declined noticeably from ―very high risk‖ levels (more than 50) to ―medium risk‖ levels (ranging from 30 to 50 ) for most spiked soils. In conclusion, DTPA and EDTA-Na are effective chelating agents in reducing the risks associated with Cs contamination in soils.
土壤Cs污染具有严重的环境威胁;因此，其整治是确保环境安全的义务。本研究旨在评价EDTA-Na或DTPA作为螯合剂去除污染土壤中Cs的效率。为了达到这一目的，选择了三种土壤(一种粘土土壤和两种砂壤土，有机质和caco3含量不同)。所研究的土壤样品分别被人工污染了50、100和200 mg Cs kg -1。对这些样品进行浸前和浸后的连续提取，以了解土壤洗涤后不同土壤组分间Cs的分布情况。本研究讨论了用所研究的螯合剂进行土壤洗涤对降低与Cs危害相关的风险评估危害的意义。关键结果表明，DTPA比edta - nadad更有效地去除污染土壤中的碳，并且两者都显著降低了土壤中的碳，特别是那些被认为是碳酸盐结合组分之外的流动组分(水溶性组分和交换性组分)。因此，对于大多数尖刺土壤，计算出的风险评估代码从“非常高风险‖水平(大于50)”明显下降到“中风险‖水平(范围从30到50)”。总之，DTPA和EDTA-Na是有效的螯合剂，可以降低土壤中Cs污染的风险。

The Wadi El-Sheikh area is situated in south Sinai, and is distinguished by a high abundance of calc-alkaline and alkaline/peralkaline granitoid rocks, as well as related volcanics. These granitoid rocks are of particular geodynamic significance because they contribute to better understanding of how the continental crust of the Arabian Nubian Shield (ANS) formed. Thus, the present study introduces new comprehensive geological field studies, petrological data, and whole rock geochemical data of syn-tectonic granitoids along Wadi El-Sheikh. The composition of the syn-tectonic granitoids (SNG) ranges from quartz-diorite, tonalite, to granodiorite. Geochemically, these SNGs are mainly metaluminous, calc-alkaline, I-type, and correspond to syn-collision volcanic arc granitoids. The investigated syn-tectonic granitoids have high (Al 2 O 3 /TiO 2) ratios (17.85–80.70), rising toward the higher silica granitoid type (granodiorite), while they also show high (CaO/Na 2 O) ratios (0.33–1.44) representing a decrease from quartz-diorite to granodiorite. These characters indicate that the emplacements of SNG were greatly influenced by the magma mixing of mafic and felsic melts. The analyzed granitoids originated at temperatures ranging from 650°C to 700°C and water pressures ranging from 0.5 to 10 kbar. According to the depth of magma segregation, and they were produced at depths of more than 30 km of the lower crust. The considered SNG are commonly concerned with enrichment of LILE and LREE and depletion of HFSE in comparison to N-MORB values (negative Ta and Nb anomalies)

. The psychological satisfaction of cancer patients is an important and effective role in the completion of the therapeutic process.

A total of 45 samples of fish (Tilapia Nilotica and Claris Lazera) were collected from EL-Bagoria canal and EL-Menofy drainage and Bahr Shibin for detection and determination of Organochlorine pesticides (DDT, aldrin and dieldrin). Organochlorine pesticides could not be detected in Bahr Shibin while mean value of DDT in Tilapia Nilotica from EL-Bagoria canal was 0.37±0.09, mean level of aldrin was 0.33±0.03 and mean level of dieldrin was 0.50±0.20 while in EL-Menofy drainage mean level of DDT was 0.34±0.07, mean level of aldrin was 0.40±0.08 and mean level of dieldrin was 0.40±0.13. While in Claris Lazera samples from EL-Bagoria canal mean level of DDT was 0.40±0.06, mean level of aldrin was 0.25±0.07and mean level of dieldrin was 0. 34±0.08 while from EL-Menofy drainage mean value of DDT was 0.27±0.05, mean level of aldrin was 0.30±0.07 and mean level of dieldrin was 0.48±0.10. Pesticides are major pollutant of water sources which are considered the natural habitat of fish On the other hand , fish could be contaminated by pesticides either directly by gills breathing or indirectly through contamination of feeding items so it is very important to analyze fish samples to detect to what extent the rate of accumulation of pesticides residues in fish flesh and organs.
