Aim of work: This study is a prospective randomized trial aiming to investigate whether radiotherapy volume can be reduced without loss of efficacy from involved field radiotherapy (IFRT) to involved node radiotherapy (INRT) after four cycles of ABVD chemotherapy in the treatment of early stage Hodgkin’s lymphoma. Patients and Methods: Between September 2009 and January 2012, all patients with newly diagnosed early-stage favorable and unfavorable Hodgkin’s lymphoma attending to the Clinical Oncology department of Cairo University, faculty of medicine were enrolled into this study after a written consent was obtained from those cases enrolled. Patients were assigned to receive (ABVD) for four cycles followed by randomization for radiotherapy into two arms one arm of 30 Gy INRT +/– 6 Gy to residual disease or another arm of 30 Gy IFRT +/– 6 Gy to residual disease. Results: 35 patients were enrolled in this study: 16 patients in the INRT arm and 19 patients in the IFRT arm. The median observation time was 25 months. The overall survival for all eligible patients was 97% and freedom from treatment failure was 85.7%. Survival rates at the end of the study revealed no differences between INRT and IFRT arms. also, in terms of complete remission post radiotherapy (14 versus 15), relapse (1 versus 4), and death (0 versus 1) respectively the outcome was similar in both arms. As regard acute and sub-acute toxicities no significant difference could be detected between both arms except that IFRT arm was associated with a higher incidence of radiation pneumonitis (4 versus 1 patient). Conclusion: Radiotherapy volume size reduction from IFRT to INRT after ABVD chemotherapy for four cycles produces similar results and less toxicity in patients with early-stage Hodgkin’s lymphoma especially in patients with mediastinal disease.

The practice of medicine in Muslim nations dates to the millennia before the advent of the religion of Islam. As far as the pre-Islamic period is concerned, what evidence is available indicates the medical evolution began nearly 6000 years ago in Mesopotamia, where medicine for the first time in history became a recognised profession. In ancient Egypt, it was practised by priest-physicians who demonstrated astonishing knowledge in various medical subjects. The origins of medicine in ancient Persia (Afghanistan, Iran, and parts of Central Asia) span the 6th century B.C. and to the Zoroastrian religious book of Avesta, which delved into such topics as preventive and clinical medicine. In reference to the account of medicine in the Arab peninsula, limited information exists. In terms of post-Islamic ages, the foundations of Islamic science were laid during the reign of the second Abbasid Caliph, al-Mansur, and the establishment of Baghdad as its capital in 762 A.D., when the Arabic translation movement commenced. During the next six centuries, medicine and other fields of science flourished, and prominent physicians such as the Bukht Yishu family, Razī, Majūsī, Avicenna, Jorjanī, al-Zahrāwī, and other scientists emerged. In both the pre- and post-Islamic ages, Islamic medicine was heavily influenced by Mesopotamian, Egyptian, Persian, Indian, and, predominantly, Greek medicine. Nevertheless, the advancements and innovations in medical science and healthcare systems that were achieved during the early and medieval Islamic ages have indubitably made an invaluable contribution to the evolution of medicine throughout the world, and to the invention of numerous procedures and practices which are still widely performed today. Hence, the value of comprehending the pivotal role Islamic medicine played (and indeed still plays) in the progression of medical practice across the globe cannot be overstated.

The red palm weevil （RPW） Rhynchophorusferrugineus is one of the most invasive insect pests causing massive damage on date palms over the world. Synthetic pyrethroid insecticide beta-cyfluthrin has been evaluated against developmental stages of RPW under laboratory conditions. These stages were exposed to residual film of the insecticide on transparent cups using a Potter precision laboratory spray tower. Percent mortality of males and females were recorded 0.5, 2.0 and 24 h after treatment. Furthermore, date palm offshoots were infested in mesh house, two months later, offshoots treated with 300 ppm （p.g/mL） beta-eyfluthrin using two methods dipping and injection. Bioassay test showed beta-cyfluthrin at 300 ppm caused 86,7% and 93,3% mortality against males and females after 2 h respectively with LC50 135.74 and 109.4 ppm. By increasing the concentration at 400 ppm, mortality reached 100% against males and females after 24 h, Developmental stages, eggs and larvae were more sensitive toward the insecticide, where at 120 ppm no eggs hatched after 96 h and 86.7% mortality was recorded at 200 ppm against larvae after 30 rain with LC50 93.19 ppm. In addition, dipping method of date palm offshoots in 300 ppm beta-cyfluthrin was a very convenient way to control all RPW stages compared to injection method. So, it possible to recommend this method for treating the date palm offshoots in such insecticide as one of the most important elements of integrated pest management for standardizing insecticide based quarantine protocols.

Diffuse large B cell primary hepatic lymphoma is a rare disease with limited available information regarding treatment strategy. although the liver contains lymphoid tissue and is an important site for lymphocytes activation, primary hepatic lymphoma is rare. Host factors make the liver a poor environment for malignant lymphoma development. Its coexistence with human immunodeficiency virus(HIV) infection increases morbidity and mortality risks. Additionally, jaundice increases chances of developing adverse effects from chemotherapy. Here, we report a case of diffuse large B cell primary hepatic lymphoma in a 32-year-old HIV positive man. Due to elevated liver enzyme levels and jaundice, the patient was initially treated with an R-DHAP regimen, which was replaced with an R-CHOP regimen. Restaging images with a positron emission tomography scan after the latest chemotherapy cycle confirmed remission. This is the first report of complete remission of primary hepatic diffuse large B cell lymphoma in an HIV positive patient in the English literature.

Journal of Sensor Technology 2016年第4期6卷 101-109页

Biocides are oilfield chemicals that are widely used to control bacterial activity throughout the oil industry. A feasibility study has been explored to develop detection techniques for biocide batch treatments, preferably on-line and in real-time, for their potential use in seawater flooding system. Several methods to measure key components of the biocide formulation were investigated and reported in previous study [1]. The enzymatic activity of an immobilized acetylcholine esterase (AChE) on the column material was successfully inhibited by some model compounds, but not by the actual biocides commonly used in Saudi Aramco seawater flooding system. In this paper, an alternative assay for biocide detection in the Saudi Aramco seawater flooding system was investigated for its applicability for the development of on-line biocide sensor. The assay was based on the detection of aldehyde functionality in the biocide mixture through measurement of a fluorescent derivative formed in the reaction of aldehyde groups and dimedone in the presence of ammonium acetate. The reaction of aldehyde groups with dimedone was demonstrated in seawater matrix, and the formed fluorescent product was successfully measured. The results showed that the dimedone-based assay was very sensitive, and relatively straightforward to perform. The ruggedness test also indicated that the assay is sensitive to minor changes of various specific conditions of the method. It is concluded that the dimedone assay is suitable for further development of a real-time biocide monitoring system to detect the presence of biocide slugs in seawater flooding system. The development of an automated on-line biocide sensor based on dimedone assay is underway.

A new interesting class of conducting polymers based on methyl-cyclohexanone in the main chain has been synthesized by solution polycodensation technique. The copolymers which containing different cycloalkanones were also synthesized. The model compound II was synthesized from the monomer I with benzaldehyde, and its structure was confirmed by elemental and spectral analyses. The resulting polymers and copolymers were characterized by elemental and spectral analyses, beside solubility and viscometry measurements. The thermal properties of those polymer and copolymers were evaluated by TGA and DSC measurements and correlated to their structural units. X- ray analysis showed that it has some degree of crystallinity in the region 2θ = 5 - 60 o .The U.V- visible spectra of some selected polymers were measured in DMSO solution and showed absorption bands in the range 265-397 nm, due to n - π* and π - π* transition. The morphological properties of selected examples were tested by SEM. The electrical conductivities in the 10- 9-10-8 ohm-1 cm-1 range were observed: doping with iodine showed a small increase.

Objective: This study aimed to evaluate the age, gender, causes, place of trauma, and type of crown fracture in permanent dentition among patients attending Liaquat University of Medical and Health Sciences Hospital (LUMHS), Jamshoro, Pakistan. Methodology: This cross-sectional study was conducted at the Operative Dentistry Department of LUMHS hospital over a period of six months. All patients (6 - 40 years of age) who had a history of dental trauma and attending dental OPD were included in this study. The data for all patients were recorded in a predesigned proforma. Data were collected on age, gender, place of trauma (playground, road, home), cause of trauma (fall, playing, road accident, bicycle accident, collisions, fighting) and associated symptoms. The data were analyzed using SPSS 22.0. Mean and the standard deviation was computed for a quantitative variable like age. Frequency and percentage were calculated for qualitative variables like gender, risk factors, and pattern of trauma. Results: A total of 82 patients were enrolled. The most frequent age group involved was 13 - 20 years (46%) with males (58.5%) predominance. The majority of trauma cases were due to fall (36.6%) while playing and 19.5% were bicycle accidents. The most commonly affected tooth was right maxillary central incisor (46.6%) followed by left maxillary central incisor (28.4%). Of the 116 teeth examined, 56.0% had a complicated crown fracture and 44.0% had an uncomplicated crown fracture. Conclusion: Safety measures should be implemented where dental traumatic accidents occur most frequently like at home and on
