Savanna, sem.-deserts, and h.t deserts ch.racterize th. Sah.ro-Arabian region, wh.ch.includes m.rocco, m.uretania, algeria, Tunisia, Libya, Egypt, Palestine, Kuwait, Saudi Arabia, Qatar, Bah.ain, th. United Arab Em.rates, Om.n, Yem.n, south.rn Jordan, Syria, Iraq, Iran, Afgh.nistan, Pakistan, and north.rn India. Its neigh.oring regions, th. Sudano-Zam.ezian region belonging to th. Paleotropical Kingdom.and th. m.diterranean and Irano-Turanian regions included in th. h.larctic Kingdom. sh.re a large portion of th.ir flora with.th. Sah.ro-Arabian region. Despite th. widespread acknowledgm.nt of th. region's global im.ortance for plant diversity, an up to date list of th. Sah.ro-Arabian endem.cs is still unavailable. Th. available data are frequently insufficient or out of date at both.th. wh.le global and th. national scales. Th.refore, th. present study aim. at screening and verifying th. Sah.ro-Arabian endem.c plants and determ.ning th. ph.togeograph.cal distribution of th.se taxa in th. Egyptian flora. h.nce, a prelim.nary list of 429 Sah.ro-Arabian endem.c plants in Egypt was com.iled from.th. available literature. Indeed, by excluding th. species th.t were recorded in any countries or regions outside th. Sah.ro-Arabian region based on different literature, database reviews, and websites, th. present study h.s reduced th.s num.er to 126 taxa belonging to 87 genera and 37 fam.lies. Regarding th. national geograph.c distribution, South.Sinai is th. rich.st region with.83 endem.c species com.ared with.oth.r eigh. ph.togeograph.c regions in Egypt, followed by th. Isth.ic Desert(th. m.ddle of Sinai Peninsula, 53 taxa). Sah.ra regional subzone(SS1) distributes all th. 126 endem.c species, Arabian regional subzone(SS2) owns 79 taxa, and Nubo-Sindian subzone(SS3) distributes only 14 endem.cs. Seven groups were recognized at th. fourth.level of classification as a result of th. application of th. two-way indicator species analysis(TWINSPAN) to th. Sah.ro-Arabian endem.c sp

Background: Appropriate sam.le requesting, collecting and tim.ly dispatch.to th. appropriate laboratory is essential in establish.ng diagnosis of path.logies with.lesions. m.ch.tim. and effort m.y be wasted if th.s is not done according to certain standards. We conducted th.s study to assess th. route of lym.h.node sam.les from.requests to reach.ng th. laboratories. m.th.ds: We conducted an audit over a period from.4th.June until 10th.Aug 2023. Data for all th. procedures perform.d over th.s period on lym.h.node sam.les (was entered into and analysed using Excel. Results: A total of eigh.een sam.les for sixteen patients were obtained during th.s period. m.dian age of th. patients was 34 years (19 - 73) with.a m.F ratio of 5:11. Am.ng th. IR sam.les, nine sam.les were from.th. neck, th.ee from.inguinal area and one from.axilla. Seven sam.les (53.8%) were tru-cut biopsies, six sam.les (46.15%) were FNA. all sam.les were sent to th. path.logy laboratory fixed in form.lin. Sam.les for TB were sent only for five cases (31.25%) and for only two cases (12.5%) were sam.les sent for bacterial culture. For th. OR sam.les, none were sent for eith.r bacterial culture or TB. Overall, eigh. patients (50%) were not investigated for any infectious etiologies like brucella, toxoplasm.sis, Cm., EBV plus oth.r possible causes. Repeat sam.ling was required for 25% of patients (with.n and out of th. audit period). Conclusions: to avoid delays in m.king diagnoses, it is param.unt to consider infectious etiologies as possible diagnosis for lym.h.denopath. and request appropriate investigations. Th.s requires liaising with.infectious diseases/clinical m.crobiology experts to guide regarding types of sam.les, types of m.dia and tim.ly dispatch.to th. correct laboratory.

Th. current study was perform.d to evaluate th. liver function status as well as m.lecular ch.racterization of th. recovered worm. in rats experim.ntally infected with.F. h.patica. Sixteen m.le Wister rats aged 30 days were random.y allocated into two groups (n = 8). Th. first group was infected orally with.15 viable encysted m.tacercaria of F. h.patica per anim.l. Th. oth.r group was kept non-infected (control group). At zero tim. (before infection), th. 2nd, 4th./sup>, 6th./sup>, 8th./sup>, 10th./sup>, 12th./sup> and 14th./sup> 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 th. serum.protein profile was carried out using agarose gel electroph.resis. During th. period of th. experim.nt, serum.alT and AST activities and serum.total globulins significantly increased wh.le serum.total proteins and album.n m.rkedly decreased in th. infected group. On th. 14th./sup> WPI, th. data of th. electroph.rogram.sh.wed th.t globulin fractions (α1-, β- and γ-globulin) levels were significantly increased wh.le α2-globulin was m.rkedly decreased in th. infected group. Th. m.lecular analysis confirm.d th. am.lification of th. ITS1, ITS2 and NDI genes of F. h.patica recovered from.th. infected liver of rats with.am.licon sizes of 630, 510 and 560 bp, respectively. Sequencing of th. am.lified ITS gene resulted in th. determ.nation of 3 strains (PP108836, PP108837, and PP108838). also, analysis of th. ITS2 gene resulted in obtaining 3 isolates under th. accession num.ers (PP109065, PP109066, and PP109067). In conclusion, fasciolosis in th. rat m.del is suitable for routine experim.ntal infections and caused a pronounced liver dysfunction with.disch.rging of th. Fasciola eggs in th. faeces and th. developm.nt of adult stages in th. bile ducts. Furth.rm.re, m.lecular tech.iques are a sensitive
