Journal of Cancer Therapy 2022年第6期13卷 331-336页

作者： Emad Mohsen Barsoum Sara el Sherif May Gamal Ashour Mohsen samy Barsoum Barsoum Oncology Center (BOC) Giza Egypt Radiation Oncology and Nuclear Medicine Department National Cancer Institute Cairo University Cairo Egypt

Follicular dendritic cell sarcomas (FDC-Sarcoma) are a rare type of tumor. Although most cases (60%) originate in the cervical, abdominal, or axillary lymph nodes, extranodal origin from secondary lymphatic tissue such as the tonsils, Waldeyer’s ring, or MALT is also prevalent (40%). We report a case of cervical FDCS in a 51-year-old female who developed invasive breast cancer during follow-up. We review the presentation and management of this disorder, emphasizing the differential diagnosis. The patient was continuously monitored and has been free of recurrences for ten years. For FDC Sarcoma of the head and neck, this case suggests surgical resection combined with chemotherapy and radiotherapy as a therapeutic option.

引用

Journal of Reproduction and Contraception 2016年第2期27卷 112-117页

作者： Tamer Said yasser el Kassar Ahmed samy el-Agwany Department of Obstetrics and Gynecology El-Shatby Maternity University Hospital Faculty of Medicine Alexandria University

Objective To test for the presence of perisigmoidal adhesions in cases with suspected endometriosis（EMS）.Methods A prospective cohort controlled study was performed. Seventy-four women with no clinical or ultrasonic evidence of ovarian cysts or EMS were included in the study. All cases were admitted to undergo laparoscopy for different indications. In all cases, thorough inspection of pelvic peritoneum was done. Then these patients were divided into two groups. Group A had no perisigmoidal adhesions（15 patients） and group B had mild filmy perisigmoidal adhesions. In both groups, documentations of visible endometriotic lesions, bipolar cauterization of selected parts of uterosacral ligaments, ovarian beds and sides of Douglas’ s pouch and histopathology assessment were done in all cases from suspicious, positive endocoaggulation and perisigmoid *** Twenty-seven patients with visible EMS had perisigmoidal adhesions. Thirtytwo patients with normal appearing peritoneum with perisigmoidal adhesions had positive electrocoagulation test in one or more pre-selected parts of the pelvic *** patients with normally appearing peritoneum without perisigmoidal adhesions had negative electrocoagulation test（bipolar cauterization turned white）.Conclusion Presence of mild filmy perisigmoidal adhesions causing tenting of the sigmoid colon could be a strong evidence of the presence of at least minimal or subtle EMS and should warrant careful inspection of the peritoneum cavity before exclusion of EMS.

Objective To define the relationship between the use of progestogen-only contracep- tion and the occurrence of abnormal cervical cytology and cervical intraepithelial lesion. Methods The present study was designed as a case-control study including 200 progestogen-only contraceptive （POC） users recruited as cases （group A） and 50 women who were non-hormonal contraceptive users as a control group （group B）. Positive Papanicolau （Pap） smear was reported in cervical cell abnormalities from atypical squamous cell of undetermined significance （ASCUS） to invasive cancer. Pap smear was evaluated according to the Bethesda system classification 2001. Cases with posi- tive Pap smears were subjected to visual inspection of the cervix with 5.0% acetic acid （VIA test） and punch biopsy. Results Statistical analysis of Pap smear results in this study showed epithelial cell abnormalities in 44 cases （22.0%） in group A and 9 cases （18.0%） in group B showing no statistically significant difference （P〉O. 05）. ASCUS abnormality was reported in 31 cases （15.5%） of group A and 6 cases of group B （12.0%）. Low-grade squamous intraepithelial lesion （LSIL） was found in 11 cases （5.5%） and 3 cases （6.0%） of group A and group B, respectively. High-grade squamous intraepithelial lesion （HSIL） was found in 2 cases （1.0%） of group A and none of group B. The incidence of abnormal Pap smears in group A did not greatly vary between different methods of POCs. Among Depo medroxyprogesterone acetate （DMPA） users, ASCUS was found in 17 cases （16.8%）, LSIL was found in 11 cases （10.8%） and HSIL was found in 2 cases （1.9%）. While in progesterone-only pills （POPs） users and Implanon~ users, ASCUS was found in 10 cases （12.8%） and 4 cases （20.0%） respectively with no higher epithelial abnormalities found. Levonorgestrel intrauterine device （LNG-IUD） was used by 1 case in group A and was not associated with Pap smear abnormality. Cases with ASCUS abnormality were followed up by repeated Pap smear after 3 mont

Prediction of the Diffuse Solar Energy on Horizontal at Different Selected Locations

引用

Energy and Power Engineering 2022年第11期14卷 635-651页

作者： samy A. Khalil Solar and Space Department National Research Institute of Astronomy and Geophysics (NRIAG) Helwan Egypt

The main objective of this paper is to predict the diffuse solar energy on a horizontal surface by using data of global solar energy (H) and diffuse solar energy (Hd) at different selected geographical locations in Saudi Arabia during the period time from 1980 to 2019. The low values of the root mean square error RMSE for all correlations indicated a good agreement between the measured and calculated values of Hd. The negative values of mean percentage error MPE % for all models show that for all locations, the proposed correlations slightly overestimate Hd, and the absolute values of MPE never reach 1.35%. The first, second and third order correlations between the diffuse solar fraction Hd/H and the clearness index Kt and between the diffuse transmittance Hd/H0 and the sunshine hours have been proposed for the selected locations using the method of regression analysis. The differences between the measured and calculated values of Hd show that a first order correlation between Hd/H and Kt can be used for estimating Hd at the present locations with good accuracy. However, second order correlations between Hd/H or Hd/H0 and S/So are recommended for estimating Hd at these locations. The average annual differences between measured and calculated values of diffuse solar energy Hd on horizontal at selected sites in the present research are discussed.

Energy and Power Engineering 2022年第10期14卷 558-593页

作者： samy A. Khalil Solar and Space Department National Research Institute of Astronomy and Geophysics (NRIAG) Cairo Egypt

The main objective of this research is to analyze the monthly average daily of global (H), beams (B) and diffuses (D) solar irradiance on a horizontal surface at four selected sites (el-Kharga, Hurghada in Egypt and Dammam, Hail in Saudi Arabia) during the period time from 1980 to 2020. The empirical models between (H/Ho) and meteorological parameters along with the values of (MBE), (RMSE), MPE, R2 and the t-Test statics are discussed. The results in this study indicate good agreement between observed and calculated values of total solar energy and diffuse solar fraction. The results for south facing surfaces of the (RMSE) for different slope at different models in the present research are discussions. Nine different models between isotropic and anisotropic used to estimate the diffuse solar radiation on a tilted surface at selected sites in this study. The absolute relative values of RMSE for the south-facing surface ranges from 7 to 41.3 at el-Kharga and Hurghada sites, Egypt in the present study for Koronakis and Stevenand Unsworth (SU) models respectively. The values of (RMSE), for the south-facing surface ranges from 9.3 to 39.7 at Dammam and Hail sites, Saudi Arabia in the present research for Koronakis and Klucher models respectively. For west-facing surface the values of RMSE range from 11.2 to 47.3 for Badescu and Koronakis models at el-Kharga and Hurghada sites, Egypt respectively, while values of RMSE range from 6.5 to 38.5 for Klucher and Reindl et al. models at Dammam and Hail sites, Saudi Arabia. The models Koronakis, Klucher and Stevenand Unsworth (SU) models are given the most accurate estimate for the south-facing surface, and Badescu, Koronakis, Klucher and Reindl et al. models are good performs better estimated for the west-facing surface.

Potential Insecticidal Effect of a Wasp (Polistes dominulus) and a Bee (Apis mellifera) Venoms in Controlling Spodoptera littoralis

引用

Advances in Entomology 2022年第4期10卷 300-319页

作者： Reham Z. Sadek Shereen M. el Banna Fayez M. Semida samy M. Zalat Zoology Department Faculty of Science Suez Canal University Ismailia Egypt

Cotton leaf worm, Spodoptera littoralis, is considered one of the most common arthropod pests that contribute to crop devastation of cotton. Previously, agricultural pests were controlled through the application of chemical insecticides. However, insecticide-resistant insect populations emergence, as well as increasing concerns about the environmental and human health risks. Venomous animals introduce valuable sources of bioactive compounds which are employed for defence. Some of these toxins have high phyletic specificity, making them appropriate for use in IPM programs. This study aims to test the insecticidal effects of Polistes dominulus and Apis mellifera venoms. Crude venoms were examined for their insecticidal effect against cotton leaf worms by four different application methods including: leaf dipping, integument dropping, spraying, and injection. The data demonstrated a strong response to purified (Polistes dominulus) venom at an initial time than that of honey bee (Apis mellifera) which increases response with increasing the dose and the time interval. A dosage of 0.015 - 0.16 ml of both venoms had notably varied in LD50 values on Spodoptera littoralis that showed higher wasp venom toxicity. Cotton leaf worms showed more susceptibility and mortality to the Polistes sp. venom than that of honey bees.
