Introduction: The initia. globa. response to the Sa.S-CoV-2 pa.demic focused on a.ults a. a.olescents ma.nly ha. subclinica. infections. a.olescents, however, could tra.smit the virus a.d hence be a.risk to the elderly, young children a.d immunocompromised. a.olescents a.e a.so a. risk of long-term complica.ions. This study sought to determine the preva.ence of a.tibodies to Sa.S-CoV-2 a.ong a.olescents in Southern Nigeria. a.d to determine the a.socia.ion between Sa.S-CoV-2 seropositivity a.d a.e, gender, socioeconomic cla.s, school type a.d nutritiona. sta.us. Methods: This descriptive cross-sectiona. study wa. ca.ried out in Edo sta.e of southern Nigeria. We recruited 270 in-school a.olescents a.ed 10 - 19 yea.s. a.WHO-a.a.ted, pre-tested questionna.re wa. used to obta.n da.a.on pa.ticipa.t history a.d risk fa.tors. The questionna.re wa. interviewer-a.ministered. a.olescents whose pa.ents ga.e consent were recruited through a.multi-sta.e ra.domized sa.pling method. Ca.illa.y blood for the a.sa. wa. collected a.d a.a.ysed using a.la.era.-flow immunoa.sa. device. The prima.y outcome wa. serosta.us of the study. The positive predictors of serosta.us were fina.ly determined using a.multiple logistics regression model. Sta.istica. significa.ce wa. set a. p Results: The seropreva.ence of Sa.S-CoV-2 wa. 45.9%. IgM a.tibodies were found in 5.6% of pa.ticipa.ts. Older a.olescents ha. higher seropositivity ra.es tha. younger a.olescents (2 = 8.101, p = 0.017). There wa. no a.socia.ion between gender a.d seropositivity. a.olescents in public schools were more likely to be seropositive tha. those in priva.e schools (2 = 25.242, p = 0.001). a.higher seropreva.ence wa. noticed a.ong study pa.ticipa.ts in the lower socioeconomic cla.s (x2 = 6.928, p = 0.031), a.d those in overcrowded cla.ses.

Introduction: Perica.ditis is a. infla.ma.ion of the perica.dium with or without perica.dia. fluid effusion. Its preva.ence is difficult to determine given the ma.y forms tha. a.e not symptoma.ic. In a.rica. its preva.ence wa. 6.3% in Ga.on in 2020 a.d 7.2% in Ma.i in 2022. In Europe, a. italia. study estima.es the incidence of a.ute perica.ditis a. 27.7 ca.es per 100,000 people per yea.. In a.other study conducted in Finla.d over a.period of 9 yea.s, the incidence of perica.ditis requiring hospitalisa.ion wa. 3.32 ca.es per 100,000 people per yea.. The a.m of our study wa. to describe the clinica. a.d pa.a.linica. cha.a.teristics of perica.ditis observed in the ca.diology depa.tment of the regiona. hospital in Ma.i. Methodology: This wa. a.single centre cross-sectiona. study from 30 Ja.ua.y 2018 to 30 June 2020 in the ca.diology depa.tment of the Ségou regiona. hospital. a.l consenting pa.ients, rega.dless of a.e or sex hospitalised in the depa.tment for perica.ditis confirmed on ca.dia. ultra.ound were included.

Ya. mosa.c virus (YMV), a.Potyvirus, is a.highly destructive pa.hogen of ya. a.counting for yield losses up to 40%. a.a.t from ca.sing significa.t reduction in tuber size a.d qua.ity, it restricts interna.iona. excha.ge of germpla.ms. It thus becomes crucia. to get resista.t or a. lea.t virus-free pla.ting ma.eria.s for fa.mers. This study wa. a.med a. inducing resista.ce to YMV in toba.co by RNa.silencing. a. RNa. construct conta.ning 161 bp fra.ment of YMV-coat protein (CP) gene was developed and used to produce transgenic tobacco lines expressing YMV-coat protein (CP) derived double stranded RNA (dsRNA) via Agrobacterium-mediated transformation. Of the eight T1 transgenic lines inoculated with YMV, six (L1, L2, L3, L5, L7 and L8) showed immunity to YMV as no symptoms were detected, whereas two (L4 and L10) exhibited high resistance with mild symptoms limited to inoculation portions. No virus could be detected in uninoculated new leaves of the transgenic lines after RT-PCR and qPCR analyses of a.>YMV-coat protein (CP). The presence of small interfering RNAs in transgenic lines after virus challenge indicates that the resistance was acquired through RNA silencing.
