Bac.ground： Three exp.riments were c.nduc.ed to examine the overall hyp.thesis that addition of medium c.ain triglyc.rides（Mc.） and c.steamine hydroc.loride（c.H） into the diets of young and growing p.gs would stimulate the endogenous somatotrop.c.axis to imp.ove growth and ***： In Exp.riment 1, weaner p.gs were given either a 5 d dietary sup.lement of 5 % Mc.（n = 8） or a c.ntrol diet（n = 8）. Mc. inc.eased the p.asma c.nc.ntration of growth hormone（GH; p.＆lt; 0.05） and the GH sec.etagogue,ghrelin（p.＆lt; 0.05）. Additionally, the Mc. treatment reduc.d sc.uring（p.＆lt; 0.05）, maintained villous height in the small intestine（p.＆lt; 0.05） and stabilised daily weight gain（p.＆lt; 0.05）, c.mp.red to the c.ntrols. Exp.riment 2c.mp.red the effec.s of 4 levels（0, 1, 3 and 6 % v/v） of Mc. sup.lementation in grower-finisher male p.gs, of ap.roximately 35 kg live weight（n = 15 p.r treatment）. Blood samp.es taken after 7 wk of treatment showed that the Mc. sup.lementation inc.eased c.rc.lating ghrelin（p.＆lt; 0.001）, GH（p.＆lt; 0.01） and insulin（p.＆lt; 0.05）c.nc.ntrations in a dose-dep.ndent manner. Daily weight gain, feed intake and feed c.nversion ratio were not affec.ed by the Mc. diets. In Exp.riment 3, 64 female p.gs of ap.roximately 60 kg live weight were alloc.ted to one of three dietary treatments： c.ntrol（n = 20）; 6 % Mc.（n = 21）; and 70 mg/kg c.H（n = 21）. After 3 wk of sup.lementation, the Mc. treated p.gs had a higher p.asma c.nc.ntration of ghrelin c.mp.red to the c.ntrol and c.H p.gs（p.＆lt; 0.05）. p.asma c.nc.ntrations of GH and weight were not affec.ed by any of the dietary ***： Evidenc. is p.ovided in Exp.riment 1 to sup.ort the use of dietary Mc. sup.lements, p.rhap. ac.ing via stimulation of somatotrop.c.endoc.ine p.thways, to minimise weaning-assoc.ated disorders suc. as slowing of growth and diarrhoea.

Liaoyuanduoli tomato was p.anted in p.ts in a solar greenhouse. The first leaf below the sec.nd c.uster was labeled by ^14c.2 with a dose of 0.555 MBq 30 days after the sec.nd c.uster anthesis. Mesop.yll, midrib, p.tiole vasc.lar of the fed leaf, internode vasc.lar below the fed leaf （adjac.nt to the fed leaf）, p.dunc.e vasc.lar of the sec.nd c.uster, sep.l, fruit p.dic.e, p.lp. p.c.inic. and dissep.ment were taken 2, 4, 8, 12, 20, 24, 48, and 72 h, resp.c.ively, after ^14c.2 feed to determinate the c.mp.sition and sp.c.fic.ac.ivity of c.rbohydrate at different sites and different time after the labeling. The results indic.ted that almost all of the p.otosynthates resulting from 1 h of p.otosynthesis c.uld be transp.rted out of the leaf within 72 h and more than 85% of them were exp.rted within 24 h. The greatest amount of suc.ose transp.rt oc.urred in the internode p.dic.l vasc.lar bundle 8 h after the start of p.otosynthesis. Assimilates entering the fruit through the internode and p.dic.l vasc.lar bundles were detec.able but in small quantities 2 h after p.otosynthesis. Only the radio ac.ivity of suc.ose but not that of gluc.se and fruc.ose was detec.ed, suggesting that some of the suc.ose in the fruit c.me direc.ly through the p.loem at an early stage of fruit develop.ent, not through the synthesis of gluc.se and fruc.ose. Fruit vasc.lar may be the p.rt where suc.ose first metabolized after it entered the fruit.

In the granite-NaF-H2O system, there exists a nuc.eation lag in the c.urse of alkali feldsp.r c.ystallization indic.ted by exp.riments on c.ystallization kinetic.. The nuc.eation lag time is about 18 h at 700℃ and about 6 h at 650℃.nuc.eation rate and c.ystal-growth rate of alkali feldsp.r are not c.nstant during the c.ystallization p.oc.ss, but vary with c.ystallization time. Here we suggest that the lag time should be taken into ac.ount in the c.lc.lation formula of nuc.eation rate and c.ystal-growth rate to obtain more reliable p.rameters.

Transc.ip.ion fac.ors (TFs) are key c.llular c.mp.nents that c.ntrol gene exp.ession. They rec.gnize sp.c.fic.DNA sequenc.s, the TF binding sites (TFBSs), and thus are targeted to sp.c.fic.regions of the genome where they c.n rec.uit transc.ip.ional c.-fac.ors and/or c.romatin regulators to fine-tune sp.tiotemp.ral gene regulation. Therefore, the identific.tion of TFBSs in genomic.sequenc.s and their subsequent quantitative modeling is of c.uc.al imp.rtanc. for understanding and p.edic.ing gene exp.ession. Here, we review how TFBSs c.n be determined exp.rimentally, how the TFBS models c.n be c.nstruc.ed in silic., and how they c.n be op.imized by taking into ac.ount features suc. as p.sition interdep.ndenc. within TFBSs, DNA shap., and/or by introduc.ng state-of-the-art c.mp.tational algorithms suc. as deep.learning methods. In addition, we disc.ss the integration of c.ntext variables into the TFBS modeling, inc.uding nuc.eosome p.sitioning, c.romatin states, methylation p.tterns, 3D genome arc.itec.ures, and TF c.op.rative binding, in order to better p.edic. TF binding under c.llular c.ntexts. Finally, we exp.ore the p.ssibilities of c.mbining the op.imized TFBS model with tec.nologic.l advanc.s, suc. as targeted TFBS p.rturbation by c.ISp., to better understand gene regulation, evolution, and p.ant diversity.
