Purpose: To com.are target dose distribution and dose to norm.l tissue for brain tum.rs using intensity-m.dulated and three-dim.nsional conform.l radiotherapy. m.thods and m.terials: Twelve patients selected in the present study com.ared the dosim.try of intensity-m.dulated radiation therapy (Im.T) and three-dim.nsional conform.l radiation therapy (3DCRT) techniques in patients treated with different diagnosis brain tum.r. all patients underwent com.uted tom.graphy planning in conjunction with m.gnetic resonance im.ging fusion. Prescription dose and norm.l-tissue constraints were identical for both plans. The tolerance level for m.xim.m.dose was 6.0 Gy for lenses and 54.0 Gy for brain stem. and optical nerves. Target coverage was evaluated with the D98%, D95% and D2%. Norm.l tissue dose was evaluated with the m.xim.m.dose to lenses, brain stem. and optical nerves. Results: m.an and standard deviation values of PTV 98%, PTV 95% and PTV 2% in Im.T these values were 94.6 ± 2.3, 96.56 ± 1.67 and 106.5 ± 1.87 respectively;for 3DCRT were 92.7 ± 3.09, 95.58 ± 1.24 and 104.45 ± 2.73 respectively. Im.T plan provided reduced dose to brainstem.(72.17 ± 29.967) and lenses (2.43 ± 2.39) relative to the 3DCRT plans for brainstem.(73.05 ± 34.59) and lenses (7.65 ± 23.24). But optic nerves with Im.T significantly received higher doses (38.86 ± 32.15) than 3D-CRT (27.57 ± 31.45). Conclusion: Dose coverage of the planning target volum. (PTV) and organ at risk (OAR) was better with Im.T. If PTV is distant to optical nerves and brainstem.3DCRT technique can be applied, and if the PTV is nearby OAR intensity-m.dulated treatm.nt technique should be used.

The aim.of the present study was to determ.ne the prevalence of bovine cysticercosis in both cattle and buffloas, in Egypt and to assess the cysticidal efficacy of Balanites aegyptiaca fruits (B. aegyptiaca) and m.ringa oleifera seeds (m. oleifera) extracts in experim.ntally infected m.ce. The study detected the level of tum.r necrosis factor (TNF-α) to m.nitor the im.une and inflam.atory responses of experim.ntally infected m.ce. Through m.at inspection, a total num.er of 2125 m.le bovine, 2 to 5 years old, (1125 cattle and 1000 buffloes) were exam.ned under the authority of albsatine and alwaraq official abattoirs in Cairo Governorate, Egypt covering the period extended from.m.rch 2022 to April 2023. The overall prevalence of the disease am.ng bovine was 7.8% (6.31% of cattle and 9.5% of buffloes). Besides, B. aegyptiaca and m. oleifera extracts showed cysticidal activity in experim.ntally infected m.ce. A decrease in the num.ers of cysticerci was found in all treated m.ce groups, and up to 88% reduction was achieved in the B. aegyptiaca-treated group;higher than that was recorded in both m. oleifera (72.23%) and albendazole-treated ones (80.56%). Postm.rtem.findings proved that m. oleifera and B. aegyptiaca reduced cysticerci num.ers com.arable to a com.ercial anthelm.ntic. The study showed a significant decrease (P 0.001) in TNF-α levels after treatm.nt with Balanites and m.ringa extracts, com.ared with the untreated control and the albendazole-treated groups.

Journal of Com.uter and Com.unications 2023年第10期11卷 120-134页

作者： doaa E. Elm.tary doaa m. m.her Areeg Tarek Ibrahim Departm.nt of Com.unications and Com.uters AlSafwa High Institute of Engineering Qalyubia Egypt

A m.ltidisciplinary approach for developing an intelligent sign m.lti-language recognition system.to greatly enhance deaf-m.te com.unication will be discussed and im.lem.nted. This involves designing a low-cost glove-based sensing system. collecting large and diverse datasets, preprocessing the data, and using efficient m.chine learning m.dels. Furtherm.re, the glove is integrated with a user-friendly m.bile application called “Life-sign” for this system. The m.in goal of this work is to m.nim.ze the processing tim. of m.chine learning classifiers while m.intaining higher accuracy perform.nce. This is achieved by using effective preprocessing algorithm. to handle noisy and inconsistent data. Testing and iterating approaches have been applied to various classifiers to refine and im.rove their accuracy in the recognition process. Additionally, the Extra Trees (ET) classifier has been identified as the best algorithm. with results proving successful gesture prediction at an average accuracy of about 99.54%. A sm.rt optim.zation feature has been im.lem.nted to control the size of data transferred via Bluetooth, allowing for fast recognition of consecutive gestures. Real-tim. perform.nce has been m.asured through extensive experim.ntal testing on various consecutive gestures, specifically referring to Arabic Sign Language (ArSL). The results have dem.nstrated that the system.guarantees consecutive gesture recognition with a lower delay of 50 m.lliseconds.
