Plant diseases generate challenging problems in commercial, agriculture and pose real economic threats to both conventional and organic farming systems. The red palm weevil (Rhynchophorus ferrugineus) (RPW) is one of the most destructive pests of palms in the world. Nowadays, control methods revolve around treatments based on chemicals, biotechnological systems using semi-chemicals or the development of the sterile insect technique (hardly sustainable at this time) and biological control. Biological control as the use of natural microorganisms, extracted products from microorganisms or genetically improved to resist or eliminate of pathogens. Our aim was to evaluate the entomopathogenicity of indigenous Beauveria bassiana and Metarhizium anisopliae obtained in Gaza strip against larvae and adults of R. ferrugineus in order to identify indigenous strains potentially suitable for Red Palm Weevil biological control. B. bassiana & M. anisopliae were isolated from larvae and adult dead of RPW from different position of Gaza strip. Morphological analysis of the isolated fungi and molecular identification was determined using PCR technique. Also, the efficiency of the isolated fungi were evaluated under lab conditions and optimized as a biological agent. On the anther hand, the ability of treated RPW male to infect females is examined and calculated using Abbott's formula. Our results showed that the B. bassiana and M. anisopliae exhibited a good biological control agent against larvae and adults of RPW. The pathogenicity of the two most virulent isolates and the toxicity assay on larvae showed a highest mortality percentage nearly to 100% by 6 days after spraying the larvae with 3.4 × 108 spores/ml of B. bassiana. The mortality percentage reaches to 90% after spraying the larvae with 3.6 × 108 spores/ml of M. anisopliae. The mortality for the adults treated with pesticide arrives to 50% and the control group 10% at the same time. The results revealed that the infection of

由于元件封装密度越来越大,电子系统的热失效正成为一个越来越困难的设计问题。本文介绍的是用有限元方法(FEM)对双列直插式(DIP)微电子封装中的稳态热传导进行的研究。虽然文章给封装设计专家提供了数据,但为了说明所使用方法的广泛适应性,也介绍了一些热传导的背景资料和有限元分析法。先后介绍了8脚和16脚DIP有限元模型的各级研究阶段。对一个先用自然对流然后用强制对流方法在空气中冷却的16脚DIP有限元模型进行了系统的热分析。通过FEM分析发现,封装中有一个复杂的三维热场。通过一功耗范围内的计算机运算,发现了温度分布和热阻随外部对流变化的规律。这项研究向用户提供了封装冷却的数据,同时着重强调了提供热阻标准定义存在的一些困难。

The purpose of the study was to evaluate the efficiency of the microwave (MW) extraction method by comparing it with a conventional method through evaluation of antimicrobial and synergism/antagonism activity of each aquatic and ethanolic extracts samples, which were extracted from the dried plants (Ficus sycomorus leaves, Lawsonia inermis leaves and Glycerrhiza glabra Linn.). Nine samples of each plant for both solvents were irradiated with MW at several power outputs (180 w, 360 w, and 540 w) in several interval times (1, 2 and 3 minutes). The antibacterial activities of extracts and the synergistic effect between plants and antibiotics were evaluated using disk diffusion method against clinical isolated Staphylococcus aureus and Escherichia coli. The result revealed that the inhibition zone for more than 50% using aquatic and ethanolic samples results (extracted in two minutes and MW power 180 w) had shown the optimum extract and better antibiotic activity for each plant. Also, the results of ethanolic extracts used against selected microorganisms showed antimicrobial and synergistic effect with most antibiotics better than aquatic extracts. Our results indicate the possibility of using MW apparatus as an extractor to obtain bioactive compounds from plants and thus used in the treatment of bacterial infections, and some results of this study were encouraging. However, the antagonistic reactions of some extracts with some antibiotics and their use in combination should be further studied for in vitro activities. It is clearly a need to be furthermore evaluated, to identify the effective components, the mode of action and the possible toxic effect in-vivo of these ingredients.

Malignant melanomas or lymphoma of the skin are malignant tumors of the skin and/or the mucous membranes whose uterine metastases are rare. The secondary uterine localizations, although rare, must be evoked in front of a pelvic tumoral syndrome, or diffuse metastases and a personal past history of melanoma, even after a long time of remission. In our observation, the evolution of the tumor in the pelvis extended to the muscular structures of the uterus and the sigmoid colon of a 72 year old patient, what made it an exceptional case. The diagnosis of these secondary localizations is a diagnosis of elimination, almost always post-operative, made on the histopathological and immunocytochemical study of the surgical specimen, supported by cytogenetics, even molecular biology. The treatment is based on chemotherapy.

作者： Al- Hazmi A. Al- Rajhi A.A. abboud E.B. 邢咏新 PO Box 902 Jizan Saudi Arabia

Objective: To report ocular complications of Rift Valley fever (RVF) during its first reported outbreak in southwest Saudi Arabia in autumn 2000. Design: Cross- sectional study of patients in a referral hospital. Participants: One hundred forty- three consecutive patients with confirmed RVF serologic test results and ocular lesions were enrolled in the study. Methods: Hospitalized patients (n=30) and outpatients (n=113) with clinical symptoms consistent with RVF, positive RVF serologic test results, and ocular abnormalities were studied. Ophthalmologic examinations, including fundus photography and fluorescein angiography, were performed. Patients were followed up at regular intervals to determine the prognosis and outcome of identified ocular abnormalities. Main Outcome Measures: Visual acuity at initial presentation and course of anterior and posterior segment complications. Results: Among 143 patients (78% males; mean age,53.2 years), 212 eyes were affected, comprising 47 eyes in 30 inpatients and 165 eyes in 113 outpatients. The mean interval between the onset of RVF and visual symptoms ranged from4 to 15 days (mean, 8.8 days). Macular or paramacular retinitis was identified in all the affected eyes (n=212) at the time of initial assessment. Lesions included retinal hemorrhages (40% ), vitreous reactions (26% ), optic disc edema (15% ), and retinal vasculitis (7% ). Anterior uveitis was present in 31% of outpatients. Fluorescein angiography of the retinitis showed early hypofluorescence with late staining of retinal lesions and blood vessels. Initial visual acuity was less than 20/200 in 80% of eyes in the outpatient group; their vision improved, deteriorated, or remained the same in 13% , 15% , or 72% , respectively. Evaluation at the last follow- up showed macular (60% ) or paramacular (9% ) scarring, vascular occlusion (23% ), and optic atrophy (20% ) in the outpatient group. Conclusions: Rift Valley fever was associated with major ocular morbidity. Ocular ma

Objective. To evaluate our clinical practice for Group B streptococcus (GBS) screening during pregnancy and antibiotic therapy during delivery, Material and methods. We performed a retrospective evaluation of our SBS screening protocol, by vaginal swab, for a period of two years, including 1,674 asymptotic patients. Intrapartum antibiotic prophylaxis was administrated for GBS-positive women. Results. The rate of GBS carriage was 6.9% . Antibiotics were administrated for 79,3% patients with GBS-positive culture. Of these women only 39% had an interval greater than four hours between antibiotic injection and delivery. In the group of patients with positive GBS culture, no newborn was infected and only 5% were colonised. In the GBS-negative group with 1.3% of the newborns were GBS positive. Conclusion. We were surprised by our low rate of GBS carriage and the non optimal application of antibiotics during labor. We reviewed our results with all our team and a prospective evaluation has been initiated.
