Pikiliwè Departm.nt of Hem.tology Campus Teaching Hospital University of Lomé Lomé Togo Departm.nt of Pediatrics Sylvanus Olympio Teaching Hospital University of Lomé Lomé Togo National Center of Research and Treatem.nt of Sickle Cell Disease Patients (CNRSD) Lomé Togo Departm.nt of Hem.tology Sylvanus Olympio Teaching Hospital University of Lomé Lomé Togo

Background: Hem.pathies were rarely observed in m.jor sickle cell disease patients som. thirty years ago, probably due to the high m.rtality rate am.ng the latter as a result of progressive com.lications. Thanks to advances in the m.nagem.nt of sickle cell disease, patients' life expectancy has increased considerably, exposing them.m.re frequently to neoplasia, including hem.tological m.lignancies. The increased risk of leukem.genesis is m.ltifactorial and linked to the pathophysiological m.chanism. of the clinical m.nifestations of sickle cell disease. Study Setting: The clinical haem.tology departm.nt of cam.us teaching hospital and the paediatric onco-haem.tology unit of Sylvanus Olym.io teaching hospital in Lom. were used as study settings. Observations: Four hem.tologic m.lignancies were collected in a cohort of 5847 m.jor sickle cell syndrom.s. The m.dian age of the patients was 31.25 years (extrem.s: 14 and 58 years) and they were predom.nantly fem.le (sex ratio m.F = 0.25). Two were on background therapy with hydroxyurea. Am.ng the four patients, there were two cases of acute lym.hocytic leukem.a, including ALL3 in a 58-year-old SS wom.n and T-ALL2 in a 12-year-old SC. Then, a case of lym.hocytic lym.hom. in a 20-year-old SS m.n was reported and finally a case of chronic m.elocytic leukem.a in a 33-year-old wom.n of Sβ+ thalassaem.a phenotype. Conclusion: To further report this coexistence, it is therefore essential to system.tically consider hem.tological m.lignancies during m.jor sickle cell syndrom.s even if there are sim.larities in the sym.tom.tology of these two serious pathological situations.

Background: The treatm.nt of brain m.tastases with radiotherapy has shifted to the use of Stereotactic Radio-surgery (SRS). The technical issue of expanding the treatm.nt volum. around the Gross Tum.r Volum. (GTV) is a current debate. Radiotherapy centers use variable GTV-PTV m.rgins, ranging from.one to 2 m.. m.terial and m.thods: We perform.d a dosim.tric com.arison in plans of twenty patients using three m.rgins: PTV zero, PTV1, and PTV2. We also developed im.ginary Peel volum.s. These volum.s are described as follows: Peel1 = PTV1 − GTV, Peel2 = PTV2 − GTV. Results: Our results showed that the m.an PTV volum. differed significantly across the different m.rgins (p = 0.000). The V12 of the brain significantly varied as a function of PTV m.rgin (p = 0.000). The target coverage and plan quality indices were not significantly different. The Peel volum. dosim.tric analysis showed that the m.an dose was significantly higher in the nearby norm.l brain tissue: Peel1 (p = 0.022) and Peel 2 (p = 0.013). Conclusion: According to our dosim.tric analysis, expanding the GTV into a PTV by 1 m. m.rgin is m.re convenient than 2 m..

The prevalence of hum.n im.unodeficiency virus (AIDS) and hepatitis B virus am.ng heavy truck drivers and their assistants has been well docum.nted globally in correlation with their behavioral characteristics. The present study aim.d to screen for hum.n im.unodeficiency virus (HIV), hepatitis B virus (HBV), and behavioral characteristics am.ng heavy truck drivers in Port Sudan. A cross-sectional study was conducted on 274 heavy truck drivers and their assistants who used the highway Port Sudan-Khartoum.in Port Sudan city during 2019-2021. data on behavioral characteristics and substance use habits were collected using a structured questionnaire, and an ELISA test was used to screen for HIV and HBV infections in the study participants. The chi-square test, odds ratio, and confidence intervals were used to find the association between behavioral characteristics and seropositive HIV/HBV. Of the 274 enrolled participants, the seroprevalence rates of HIV were 2.7% and HBV was 23.7%. Ninety-four (34.3%) of them.had a history of high-risk sexual behavior outside of m.rriage;only two (0.7%) used condom.;14.2% of participants reported alcohol use;and 1.1% reported drug use. Univariate analysis revealed that having a sex history outside of m.rriage with ≥1 sex partner and never using a condom.with a spouse or casual partner were significant risk factors for HIV and HBV am.ng drivers. Fortunately, we found that m.st of the drivers reported low alcohol and drug use. Concerning this study, the seroprevalence of HIV and HBV is highly associated with a history of having sex outside of m.rriage and sexual behavior am.ng truck drivers and assistances. Additional studies are needed to further investigate other STIs and behavioral characteristics associated with factors in truck drivers/assistance in different truck stop regions in Sudan.

Effects of B[a]P-UVA Co-Exposure on Epigenetic m.rks of Isolated Skin Cells and Im.act of an Arundo donax L. Extract of These Changes

引用

Journal of Cosm.tics, Derm.tological Sciences and Applications 2024年第3期14卷 253-269页

作者： m.rie m. Dorr m.gali Favre-m.rcuret Katell Vié Richard Fitoussi Laboratoires Clarins Pontoise France

Background: Extrinsic aging results from.environm.ntal stressors such as UVR or pollutants. While the effects of single pollutants are better understood, those of their com.ination rem.in poorly scrutinized. Objective: Building on a study showing downregulation of several processes upon co-exposure to B[a]P and UVA, we investigated changes induced by epigenetic m.rks. m.terials and m.thods: Hum.n prim.ry fibroblasts and HaCaT cells were exposed to B[a]P and UVA. After 24 hours, exposed and unexposed cells were com.ared to assess DNA m.thylation. Focusing on HaCaT, m.ltiplex assays enabled quantifying histone H3 m.difications and evaluating four splicing factors (SRSF1, SRSF3, SFPQ, and SF3B1) by im.unohistochem.cal labeling. The expression of keratinocyte-/fibroblast-relevant genes was assessed by RT-qPCR. Finally, the im.act of an Arundo donax L. extract added 24 hours before B[a]P-UVA co-exposure was analyzed. Results: Exposure to B[a]P-UVA raised DNA m.thylation (HaCaT: ×3.6, fibroblasts: ×1.9), an increase prevented by the extract. In HaCaT cells, B[a]P-UVA increases the frequency of S10P (+38%). When exposure was preceded by extract treatm.nt, the frequency of several m.thylations was im.acted. B[a]P-UVA only induced the expression of SRSF1 and SFPQ in HaCaT (+46% and +34%). Treatm.nt with the extract abolished this effect. Co-exposure increases the expression of inflam.ation-related genes (IL-1α, IL-1β) in HaCaT cells and decreases those of AQP3, KRT15, and SOD2. The extract has little effect on these changes. In prim.ry fibroblasts, exposure to B[a]P-UVA lowered the expression of LOXL2, LUm. and TGFBR2 (−38%, −59%, and −51%, respectively), and the extract did not affect these m.difications. Conclusion: Within 24 hours, a single B[a]P-UVA co-exposure changes epigenetic m.rks of skin cells but has only m.ld effects on gene expression. An Arundo donax L. extract can prevent part of the epigenetic m.rks’ changes and could stim.late the expression of som. genes in

Com.uters, m.terials & Continua 2024年第4期79卷 243-262页

作者： Yasm.ne m.Ibrahim.Reem.Essam.ldin Saad m.darwish Departm.nt of Inform.tion Technology Institute of Graduate Studies and ResearchAlexandria UniversityAlexandria21526Egypt Faculty of Com.uters and Inform.tion Technology Egyptian E-Learning University(EELU)Giza12611Egypt Faculty of Com.uters and data Science Alexandria UniversityAlexandria21554Egypt

Detecting hate speech autom.tically in social m.dia forensics has em.rged as a highly challenging task due tothe com.lex nature of language used in such platform.. Currently, several m.thods exist for classifying hatespeech, but they still suffer from.am.iguity when differentiating between hateful and offensive content and theyalso lack accuracy. The work suggested in this paper uses a com.ination of the Whale Optim.zation Algorithm.WOA) and Particle Swarm.Optim.zation (PSO) to adjust the weights of two m.lti-Layer Perceptron (m.Ps)for neutrosophic sets classification. During the training process of the m.P, the WOA is em.loyed to exploreand determ.ne the optim.l set of weights. The PSO algorithm.adjusts the weights to optim.ze the perform.nceof the m.P as fine-tuning. Additionally, in this approach, two separate m.P m.dels are em.loyed. One m.Pis dedicated to predicting degrees of truth m.m.ership, while the other m.P focuses on predicting degrees offalse m.m.ership. The difference between these m.m.erships quantifies uncertainty, indicating the degree ofindeterm.nacy in predictions. The experim.ntal results indicate the superior perform.nce of our m.del com.aredto previous work when evaluated on the davidson dataset.
