The current study was perform.d to evaluate the liver function status as well as m.lecular characterization of the recovered worm. in rats experim.ntally infected with F. hepatica. Sixteen m.le Wister rats aged 30 days were random.y allocated into two groups (n = 8). The first group was infected orally with 15 viable encysted m.tacercaria of F. hepatica per anim.l. The other group was kept non-infected (control group). At zero tim. (before infection), the 2nd, 4th, 6th, 8th, 10th, 12th and 14th weeks post-infection (WPI), blood and serum.sam.les were collected via puncture of retro-orbital plexus of veins from.each rat. Serum.enzym. level (AST and ALT) and total protein were m.asured, and the serum.protein profile was carried out using agarose gel electrophoresis. During the period of the experim.nt, serum.ALT and AST activities and serum.total globulins significantly increased while serum.total proteins and album.n m.rkedly decreased in the infected group. On the 14th WPI, the data of the electropherogram.showed that globulin fractions (α1-, β- and γ-globulin) levels were significantly increased while α2-globulin was m.rkedly decreased in the infected group. The m.lecular analysis confirm.d the am.lification of the ITS1, ITS2 and NDI genes of F. hepatica recovered from.the infected liver of rats with am.licon sizes of 630, 510 and 560 bp, respectively. Sequencing of the am.lified ITS gene resulted in the determ.nation of 3 strains (PP108836, PP108837, and PP108838). Also, analysis of the ITS2 gene resulted in obtaining 3 isolates under the accession num.ers (PP109065, PP109066, and PP109067). In conclusion, fasciolosis in the rat m.del is suitable for routine experim.ntal infections and caused a pronounced liver dysfunction with discharging of the Fasciola eggs in the faeces and the developm.nt of adult stages in the bile ducts.

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.

作者： Sara S. Osm.n Adam.A. m.ttar omnia m. Ham.d Faculty of Public Health Alzaiem Alazhari University Khartoum Sudan Faculty of m.dical Laboratory Sciences University of Medical Sciences & Technology Khartoum Sudan

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.

Adapting Integrated High Concentrated PV m.dules and Evacuated Tube Collectors to m.nim.ze Building Energy Consum.tion in Hot Clim.te

引用

Sm.rt Grid and Renewable Energy 2019年第10期10卷 237-256页

Energy consum.tion in buildings is considered a significant portion of gross power dissipation, so a great effort is required to design efficient construction. In severe hot weather conditions as Kuwait, energy required for building cooling and heating results in a huge energy loads and consum.tion and accordingly high em.ssion rates of carbon dioxide. So, the m.in purpose of the current work is to convert the existing institutional building to near net-zero energy building (nNZEB) or into a net-zero energy building (NZEB). A com.ination of integrated high concentrated photovoltaic (HCPV) solar m.dules and evacuated tube collectors (ETC) are proposed to provide dom.stic water heating, electricity load as well as cooling consum.tion of an institutional facility. An equivalent circuit m.del for single diode is im.lem.nted to evaluate triple junction HCPV m.dules efficiency considering concentration level and tem.erature effects. A code com.atible with TRNSYS subroutines is introduced to optim.ze evacuated tube collector efficiency. The developed m.dels are validated through com.arison with experim.ntal data available from.literature. The efficiency of integrated HCPV-ETC unit is optim.zed by varying the different system.param.ters. Transient sim.lation program.(TRNSYS) is adapted to determ.ne the perform.nce of various parts of HCPV-ETC system. Furtherm.re, a theoretical code is introduced to evaluate the environm.ntal effects of the proposed building when integrated with renewable energy system.. The integrated HCPV-ETC fully satisfies the energy required for building lighting and equipm.nt. Utilizing HCPV m.dules of orientation 25? accom.lishes a m.nim.m.energy payback tim. of about 8 years. Integrated solar absorption chiller provides about 64% of the annual air conditioning consum.tion needed for the studied building. The energy payback period (EPT) or solar cooling system.is about 18 years which is significantly larger than that corresponding to HCPV due to the e
