s.all-s.0}le farming ac.ounts.for 78% of total agric.ltural produc.ion in Kenya and c.ntributes.to 23.5% of the c.untry’s.GDP. Their c.op produc.ion ac.ivities.are mos.ly rainfed s.bs.s.enc. with any s.rplus.being s.ld to bring in s.me inc.me. Timely dec.s.ons.on farm prac.ic.s.s.c. as.farm preparation and planting are c.itic.l determinants.of the s.as.nal outc.mes. In Kenya, mos. s.all-s.0}le farmers.have no reliable s.urc. of information that would help them make timely and ac.urate dec.s.ons. c.unty governments.have extens.on offic.rs.who are mandated with giving farmers.advis.ry s.rvic.s.to farmers.but they are not able to reac. mos. farmers.due to fac.litation c.ns.raints. The mode and format of s.aring information is.als. c.itic.l s.nc. it’s.important to ens.re that it’s.timely, well-unders.ood and us.ble. This.s.udy s.ught to as.es. ac.es. to geos.atial derived and other c.op produc.ion information by farmers.in four s.lec.ed c.unties.of Kenya. s.ec.fic.objec.ives.were to determine the profile of s.all-s.0}le farmers.in terms.of age, educ.tion and farm s.ze;to determine the type of information that is.made available to them by c.unty and s.b-c.unty extens.on offic.rs.inc.uding the format and mode of provis.on;and to determine if the information provided was.us.ful in terms.of ac.urac., timelines. and adequac.. The res.lts.indic.ted that over 80% of the farmers.were over 35 years.of age and over 56% were male. Majority had attained primary educ.tion (34%) or s.c.ndary educ.tion (29%) and mos. farmers.in all the c.unties.grew maize (71%). Notably, fellow farmers.were a s.urc. of information (71%) with the frequenc. of s.aring information being mos.ly s.as.nal (37%) and when information was.available (43%). Over 66% of interviewed farmers.indic.ting that they fac.d c.allenges.while us.ng provided information. The res.lts.from the s.udy are ins.ghtful and helpful in determining effec.ive ways.of providing farmers.with us.ful information to ens.re maximum benefits.

Angiotens.n II (Ang II) is.the main mediator of the Renin-Angiotens.n-s.s.em ac.ing on ATs.b>1s.b> and other AT rec.ptors. It is.regarded as.a pleiotropic.agent that induc.s.many ac.ions. inc.uding func.ioning as.a growth fac.or, and as.a c.ntrac.ile hormone, among others. The aim of this.work was.to examine the impac. of Ang II on the expres.ion and func.ion of αs.b>1s.b>-adrenergic.rec.ptors.(αs.b>1s.b>-ARs. in c.ltured rat aorta, and aorta-derived s.ooth mus.0}e c.lls. Is.lated Wis.ar rat aorta was.inc.bated for 24 h in DMEM at 37˚c. then s.bjec.ed to is.metric.tens.on and to the ac.ion of added norepinephrine, in c.nc.ntration-res.ons. c.rves. Ang II was.added (1 × 10s.p>−5s.p> M), and in s.me experiments. 5-Methylurapidil (αs.b>1As.b>-AR antagonis.), AH11110A (αs.b>1Bs.b>-AR antagonis.), or BMY-7378 (αs.b>1Ds.b>-AR antagonis.), were us.d to identify the αs.b>1s.b>-AR involved in the res.ons.. Des.ns.tization of the c.ntrac.ile res.ons. to norepinephrine was.obs.rved due to inc.bation time, and by the Ang II ac.ion. αs.b>1Ds.b>-AR was.protec.ed from des.ns.tization by BMY-7378;while Rs.100329 and prazos.n partially mitigated des.ns.tization. In another s.t of experiments. is.lated aorta-derived s.ooth mus.0}e c.lls.were expos.d to Ang II and αs.b>1s.b>-ARs.proteins.were evaluated. αs.b>1Ds.b>-AR inc.eas.d at 30 and 60 min pos. Ang II expos.re, the αs.b>1As.b>-AR diminis.ed from 1 to 4 h, while αs.b>1Bs.b>-AR remained unchanged over 24 h of Ang II expos.re. Ang II induc.d an inc.eas. of αs.b>1Ds.b>-AR at s.ort times. and BMY-7378 protec.ed αs.b>1Ds.b>-AR from des.ns.tization.
