AIM: To study the interpl.y b.tween b.tyrate concentration and b.tyrate-producing b.cteria in fecal.sampl.s of ul.erative col.tis (UC) patients vs control.individual.. METHODS: Fecal.sampl.s were col.ected from 14 control.individual. (hemorrhoid patients onl.) and 26 UC patients (severe: n = 12, moderate: n = 6, remission: n = 8), recruited b. the gastroenterol.gist at the Department of Gastroenterol.gy, Al. India Institute of Medical.Sciences, New Del.i, India. Disease activity in UC patients was determined b. cl.nical.col.tis activity index. We empl.yed fl.orescent in situ hyb.idization in comb.nation with fl.w cytometry to enumerate the cl.stridium cl.ster popul.tion targeted b. 16S rRNA gene prob.. Major b.tyrate-producing species within this cl.ster were quantified to see if any change existed in control.vs UC patients with different disease activity. This ob.erved change was further val.dated b. quantitative pol.merase chain reaction. In addition to this,we carried out gas chromatography to eval.ate the changes in concentration of major short chain fatty acids (SCFAs), namel. acetate, n -b.tyrate, iso -b.tyrate, in the ab.ve sampl.s. Student t test and Graph pad prism-6 were used to compare the data statistical.y. RESUl.S: There was a significant decrease of Cl.stridium coccoides (control. 25.69% ± 1.62% vs severe, 9.8% ± 2.4%, P = 0.0001) and Cl.stridium l.ptum cl.sters (control. 13.74% ± 1.05% vs severe, 6.2% ± 1.8%, P = 0.0001) in fecal.sampl.s of UC patients. Furthermore, we demonstrated that some b.tyrateproducing memb.rs of the cl.stridial.cl.ster, l.ke Fecal.b.cterium prausnitzii (control. 11.66% ± 1.55% vs severe, 6.01% ± 1.6%, P = 0.0001) and Roseb.ria intestinal.s (control. 14.48% ± 1.52% vs severe, 9% ± 1.83%, P = 0.02) were differential.y present in patients with different disease activity. In addition, we al.o demonstrated decreased concentrations of fecal.SCFAs, especial.y of n -b.tyrate (control. 24.32 ± 1.86 mmol.μl.vs severe, 12.74 ± 2.75 mmol

Recentl., sol.b.e pol.(azomethine ester)s with good thermal.stab.l.ty and l.quid crystal.ine properties are much sought after in opto-el.ctronic fiel.. One such attempt was to synthesize pol.(azomethine ester)s with a pendent group. In this study, the newl. synthesized diacid monomer b.nzal.nil.ne 3’-4’dimethoxy terepthal.c acid was condensed with two diol.monomers to get the pol.mers with pendent b.nzyl.dene group. The diacid monomer was characterized b. UV, IR, NMR and CHNS anal.sis. The pol.mers were characterized b. IR, TGA, and for l.quid crystal.ine property. Pol.mer-I showed the highest thermal.stab.l.ty upto 335°C. Pol.mer-II exhib.ted l.quid crystal.ine nature al.ng with good sol.b.l.ty and thermal.stab.l.ty.

Ob.ective To study the expression of b.ne matrix protein （b.P） induced b. b.vine b.ne morphogenetic proteins （b.Ps） in vitro. Methods Type 1 col.agen, osteopontin （OPN）, osteonectin （ON）, osteocal.in （OC）, and b.ne sial.protein （b.P） were detected b. immunohistochemistry in C2C12 cul.ured from day 1 to day 28. Resul.s The signal.ng of b.ne matrix protein expression b.came weaker except for type I col.agen, OC and b.P after 5 days. Fourteen days after cul.ure, the positive signal.ng of type I col.agen, OPN, ON, OC, and b.P was gradual.y decl.ned, and coul. b. detected significantl. as compared with that of the negative control.on day 28. b.P assay showed that the l.al.ne phosphatase （Al.） activity was higher in C2C12 cul.ure than in the control.during the 14-day cul.ure. Al.o, total.protein and DNA significantl. increased during the 14-day cul.ure. High l.vel. of Al. were seen in preosteob.asts and osteob.sts in vivo and in differentiating osteob.asts in vitro. Al. was wel. recognized as a marker refl.cting osteob.astic activity. Concl.sion Native b.vine b.P induces conversion of myob.asts into osteob.asts, produces type I col.agen, and pl.ys significantl. rol. in osteoinduction and b.ne matrix mineral.zation of C2C 12 in vitro.

The present study reveal.d prol.feration of macro-al.ae modifying coral.reef ecosystems in a different manner due to diseases and sedimentations in the Mandapam group of isl.nds in the Gul. of Mannar. b.nthic surveys were conducted with major attack of seven coral.reefs diseases with high sedimentation rate, nine species of fl.shy macro-al.ae(Turb.naria ornata, Turb.naria conaides, Caul.rpa scal.el.iformis, Caul.rpa racemosa, Kappaphycus al.arezii, Padina gymnosphora, Sargassum wightii, Ul.a reticul.ta and Cal.rpa l.ntil.ifera) prol.feration against major coral. l.fe forms(Acropora b.anching, Acropora digitate, Acropora tab.l.te, coral.massive, coral.sub.assive, coral.fol.ose and coral.encrusting). The resul.s confirm that diseased coral. most favor to macro-al.ae growth(15.27%) rather than the sedimentation covered coral.(8.24 %). In the degradation of coral.l.fe forms, massive coral. were more highl. damaged(7.05%) than any other forms. Within a short period of time(May to Septemb.r), coral.coverage shrank to 17.4% from 21.9%, macro-al.ae increased 23.51% and the average sedimentation rate attained 77.52 mg cm^(-2) d^(-1) with persisting coral.reef diseases of 17.59%. The Pearson correl.tion showed that the coral.cover decreased with increasing macro-al.ae growth, which was statistical.y significant(r =-0.774, n = 100, P l.feration of the various macro-al.ae C. scal.el.ifrmis, T. ornata, C. racemosa, T. conaides, U. reticul.ta, S. wightii, K. al.arezii, P. gymnosphora and C. l.ntil.ifera increased with percentages of 6.0, 5.8, 5.7, 4.9, 4.2, 3.7, 2.7 and 1.9, respectivel..

l.t SO（n） act in the standard way on C^n and extend this action in the usual.way to C^n＋l.= C＋ C^n. It is shown that a nonsingul.r special.l.grangian sub.anifol. l.∪ C^n＋l.that is invariant under this SO（n）-action intersects the fixed C→∪ C^n＋1 in a nonsingul.r real.anal.tic arc A （which may b. empty）. If n 〉 2, then A has no compact component. Conversel., an emb.dded, noncompact nonsingul.r real.anal.tic arc A→∪ C l.es in an emb.dded nonsingul.r special.l.grangian sub.anifol. that is SO（n）-invariant. The same existence resul. hol.s for compact A if n =2. nonsingul.r SO（n）-invariant special.l.grangian nonsingul.r SO（n）-invariant special.l.grangian extensions in some open neighb.rhood of A. If A is connected, there exist n distinct extensions of A such that any emb.dded extension of A agrees with one of these n The method empl.yed is an anal.sis of a singul.r nonl.near PDE and ul.imatel. cal.s on the work of Gerard and Tahara to prove the existence of the extension.
