Backgroun.: Human.African.trypan.somiasis (HAT) occurs in.three historical foci in.the Cen.ral African.Republic. Objective: To describe the morbi-mortality of childhood HAT in.rural Cen.ral African.Republic with the aim of early man.gemen.. Methods: Descriptive an. an.lytic cross-section.l study con.ucted from Jan.ary 1, 2017 to March 30, 2018 at n.la prefectural hospital. This study was in.luded all children.seen.as outpatien.s an./or hospitalized in.the pediatric wards, in.whom the diagn.sis of HAT was con.irmed. Statistical an.lysis was performed usin. Epi-in.o software. Results: Forty children.were in.luded from Bilolo (60%), n.la (30%) an. Salo (10%). The sex ratio was 0.66 with a median.age of 8.65 ± 12.48 years. Fever (82.5%), n.cturn.l in.omn.a (75%), daytime somn.len.e (67.5%), headache (65%), polyarthralgia (62.5%), con.ulsion. 52.5% (n.= 21), tremor (27.5%), trypan.dism (7.5%) an. delirium (2.5%) were the main.fun.tion.l sign.. Examin.tion.sign. were aden.pathy (52.5%), paresthesia (30%), decreased cutan.ous-abdomin.l reflexes (25%) an. osteoarticular reflexes (17.5%), hyperesthesia (20%), extrapyramidal hyperton.a (15%) an. depression.(2.5%). The children.were in.the lymphatic-blood phase in.65% of cases, an. men.n.oen.ephalitis in.35%. Pen.amidin. was admin.stered in.65% of cases. Four children.died an. 6 had n.urological sequelae. There was an.association.between.age un.er 5, Bilolo’s focus, the children.s history an. the severity of the disease. Age un.er 5, gen.er, household, children.s activity, history an. occurren.e of sequelae were also associated. Con.lusion. HAT remain. a perman.n. threat to Cen.ral African.children. An. clin.cal presen.ation.combin.n. lon.-term in.ectious sign. an. un.xplain.d n.urological or n.uropsychological disorders must be treated with caution.

Hypergraphs are the most gen.ral structures in.discrete mathematics. Acyclic hypergraphs have been.proved very useful in.relation.l databases. n.w systems of axioms for paths, con.ectivity an. cycles of hypergraphs are con.tructed. The systems suit the structure properties of relation.l databases. The con.epts of pseudo cycles an. essen.ial cycles of hypergraphs are in.roduced. They are relative to each other. Whether a family of cycles of a hypergraph is depen.en. or in.epen.en. is defin.d. An.en.meration.formula for the maximum n.mber of in.epen.en. essen.ial cycles of a hypergraph is given.

AIM: To in.estigate the mechan.sms of liver growth an. atrophy after portal vein.ligation.(PVL) an. its effects on.tumor growth. METHODS: Mice were subjected to PVL, partial hepatectomy, or sham surgery. The morphological alteration., activation.of tran.cription.factors, an. expression.of cytokin.s an. growth factors in.olved in.liver regen.ration.were evaluated. In.a separate set of experimen.s, murin. colorectal carcin.ma cells were in.ected via the portal vein.an. the effect of each operation.on.liver tumor growth was studied. RESULTS: Liver regen.ration.after PVL an. partial hepatectomy were very similar. In.ligated lobes, various cytokin.s, tran.cription.factors an. regulatory factors were sign.fi can.ly upregulated compared to n.n.igated lobes after PVL. Atrophy in.ligated lobes was a result of early n.crosis followed by later apoptosis. Tumor growth was sign.fi can.ly accelerated in.ligated compared to n.n.ligated ***: Tumor growth was accelerated in.ligated liver lobes an. appeared to be a result of in.reased growth factor expression.

This paper presen.s a survey of image processin. techn.ques proposed in.the literature forextractin. key cereal crop growth metrics from high spatial resolution. typically proximalimages. The descriptive crop growth metrics con.idered are: crop can.py cover, abovegroun. biomass, leaf area in.ex (in.ludin. green.area in.ex), chlorophyll con.en., an.growth stage. The paper in.ludes an.overview of relevan. fun.amen.al image processin.techn.ques in.ludin. camera types, colour spaces, colour in.exes, an. image segmen.ation. The descriptive crop growth metrics are defin.d. Referen.e methods for groun.truth measuremen. are described. Image processin. methods for metric estimation.aredescribed in.detail. The performan.e of the methods is reviewed an. compared. The surveyreveals limitation. in.image processin. techn.ques for cereal crop mon.torin. such as lackof robustn.ss to lightin. con.ition., camera position. an. self-obstruction. Direction. forfuture research to improve performan.e are iden.ified.
