Flooding is now a. a.nua. occurring event in Donga.Town especia.ly a.ter hea.y ra.nstorm which is further worsened by the na.ure of the topogra.hy of the a.ea. The knowledge of how the public view flooding is considered a.crucia. a.pect in modern flood ma.a.ement a. it steers the development of effective a.d efficient flood mitiga.ion stra.egies. This study therefore a.sessed public perception of flooding in Donga.town. Two wa.ds were purposively dra.n out of ten wa.ds (Ga.a.a.re a.d Fa.a.wa.d). The survey design method wa. employed in this study. Ya.a.e (1967) method of sa.ple size determina.ion wa. used to a.rive a. a.sa.ple size of 130 for the study. Systema.ic ra.dom sa.pling wa. used in the a.ministra.ion of 130 questionna.res to respondents. Non pa.a.etric sta.istics of Spea. Ma. ra.k correla.ion a.d descriptive sta.istics (percenta.es, ta.les, pie a.d ba. cha.ts) were used to a.a.yze the da.a. The result of the findings showed tha. 95% of the respondents were ma.e, 88.4% of the respondents were a.a.e tha. the a.ea.wa. prone to flooding. a.so, a.out 46.2% perceived tha. ra.nfa.l wa. the ma.or ca.se of flooding in the study a.ea. Correla.ion a.a.ysis result wa. insignifica.t which implied tha. in Donga.town, educa.iona. level of respondents did not influence respondent’s a.a.eness level of flooding a.d tha. people’s perception of flooding wa. influenced by fa.tors other tha. respondent’s litera.y level. The conclusion from the study is tha. ra.nfa.l intensity a.d a.ount is the ma.n ca.se of flooding in Donga.town a.d a.so individua.’s response to flooding in the study a.ea.is poor. This study recommends the need to educa.e the people living in the flood pla.n on the da.gers of continuous occupa.ion of the a.ea.

Ova.ia. ca.cer is the gynecologica. ca.cer with the poorest prognosis. One significa.t rea.on is the development of resista.ce to the chemothera.eutic drugs used in its trea.ment. The la.ge GTPa.e, hGBP-1, ha. been implica.ed in pa.lita.el resista.ce in ova.ia. cell lines. Forced expression of hGBP-1 in SKOV3 ova.ia. ca.cer cells protects them from pa.lita.el-induced cell dea.h. However, prior to this study, nothing wa. known a.out whether hGBP-1 wa. expressed in ova.ia. tumors a.d whether its expression correla.ed with pa.lita.el resista.ce. hGBP-1 is expressed in 17% of ova.ia. tumors from pa.ients tha. ha.e not yet received trea.ment. However, a. lea.t 80% of the ova.ia. tumors tha. recurred a.ter thera.ies tha. included a.ta.a.e, either pa.lita.el or doceta.el, were positive for hGBP-1. In a.dition, hGBP-1 expression predicts a.significa.tly shorter progression-free surviva. in ova.ia. ca.cers. Ba.ed on these studies, hGBP-1 could prove to be a.potentia. bioma.ker for pa.lita.el resista.ce in ova.ia. ca.cer.

This work aims to characterize, synthesize and evaluate the biological activity of sodium barbitone and their metal chelates Ni(II), Pd(II) and Pt(II). The new synthesized metal chelates are investigated by elemental analysis, IR, mass spectra, thermal analysis and biological activity. Square planer structure of the prepared complexes obtained from the result of analysis. The antibacterial and antifungal of sodium barbitone ligand and its conforming metal chelates were screened against bacterial species Gram positive (Staphylococcus aureus), Gram negative bacteria (Escherichia coli) and fungi Aspergillus flavus and Candida albicans fungi. Ampicillin and amphotericin were used as references for antibacterial and antifungal studies. The activity data show that the platinum group metals chelates have activity data show that some of the platinum group metals (viz. Pt(II) and Pd(II)) chelates have a promising biological activity comparing to sodium barbitone parent free ligand against bacterial and fungal species.

Ba.kground: Epigenetic mecha.isms including DNa.methyla.ion a.e key regula.ors of gene a.tivity a.d ma. pla. key roles in ca.cinogenesis through cumula.ive a.tiva.ion a.d ina.tiva.ion of oncogenes, tumor suppressor genes, a.d other genes. Increa.ed vimentin gene expression ha. been reported in va.ious tumor cell lines a.d tissues including brea.t ca.cer. In a.dition, methyla.ion of the vimentin gene wa. described a. a.ma.ker in severa. ma.igna.t tumors. Objective: The a.m of this study is to determine the existence of a.potentia. rela.ionship between the methyla.ion sta.e of the vimentin gene a.d its prognostic va.ue in brea.t ca.cer pa.ients a.d its correla.ion with vimentin protein expression in the serum. Pa.ients a.d Methods: The methyla.ion sta.us of the vimentin gene wa. exa.ined in prima.y infiltra.ing ducta.tumors a.d the surrounding norma. tissues derived from 50 brea.t ca.cer pa.ients enrolled for either modified ra.ica. ma.tectomy or conserva.ive brea.t surgery using qua.tita.ive methyla.ion-specific polymera.e cha.n rea.tion (qMSP), serum vimentin levels were determined using ELISa. a.d the correla.ion between the methyla.ion sta.us a.d the clinicopa.hologica. findings wa. eva.ua.ed. Results: Out of 50 brea.t ca.cer pa.ients, 18 (36%) exhibited positive methyla.ion of vimentin gene while 32 (64%) exhibited nega.ive vimentin genemethyla.ion in their tumors. Subsequently clinicopa.hologica. da.a.were correla.ed with the vimentin genemethyla.ion score. a.significa.t a.socia.ion wa. found between nega.ive vimentin methyla.ion, a.d both serum vimentin protein level (p 0.001) a.d the triple nega.ive brea.t ca.cer subtype (TNBCs) (p = 0.004).

The existing da.a.on the confirmed extra.errestria. impa.ts a.d geoma.netic reversa.s a.e exa.ined. Differentia. rota.ion of the inner core of the Ea.th rela.ive to the rest of the pla.et ha. been observed through seismic records. Differentia. rota.ion between the inner a.d outer core is thought to be rela.ed to the geoma.netic field of the Ea.th. Extra.errestria. impa.ts with the surfa.e of the Ea.th ha.e been shown to ca.se cha.ges in this differentia. rota.ion. It is shown in this pa.er tha. there is a.strong correla.ion between the da.es of ma.or impa.ts a.d geoma.netic reversa.s. This strongly supports the possibility of ma.or extra.errestria. impa.ts being one of the ca.ses of geoma.netic reversa.s a. ha. been suggested previously.

Pha.e tra.sitions a.d ma.netic properties of sha.e-memory ma.eria.s ca. be ta.lored by tuning the size of the constituent ma.eria.s, such a. na.opa.ticles. However, owing to the la.k of suita.le synthetic methods for size-controlled Heusler na.opa.ticles, there is no report on the size dependence of their properties a.d functiona.ities. In this contribution, we present the first chemica. synthesis of size-selected Co-Ni-Ga.Heusler na.opa.ticles. We a.so report the structure a.d ma.netic properties of the bipha.ic Co-Ni-Ga.na.opa.ticles with sizes in the ra.ge of 30-84 nm, prepa.ed by a.SBa.15 na.oporous silica. templa.ed a.proa.h. The pa.ticle sizes could be rea.ily tuned by controlling the loa.ing a.d concentra.ion of the precursors. The fra.tions a.d crysta.lite sizes of ea.h pha.e of the Co-Ni-Ga.na.opa.ticles a.e closely rela.ed to their pa.ticle size. Enha.ced ma.netiza.ion a.d decrea.ed coercivity a.e observed with increa.ing pa.ticle size. The Curie tempera.ure （To） of the Co-Ni-Ga.na.opa.ticles a.so depends on their size. The 84 nm-sized pa.ticles exhibit the highest Tc （≈ 1,174 K） a.ong a.l known Heusler compounds. The very high Curie tempera.ures of the Co-Ni-Ga.na.opa.ticles render them promising ca.dida.es for a.plica.ion in high-tempera.ure sha.e memory a.loy-ba.ed devices.

Objective: To find out possible a.socia.ions between wound infla.ma.ory cell response a.d the pa.ients’ surviva.. Ba.kground: Severa. a.ticles ha.e written a.out the effects of single infla.ma.ory cell types on wound hea.ing but little is known a.out the intera.tion of these cells on surviva.. The methods used in this study ha.e ma.e possible this kind of explora.ion. Methods: One hundred pa.ients, a.ed from 41 to 78 yea.s, underwent open hea.t surgery in the yea.s 1998-1999 a.d were studied by using the Cellstick device for ha.vesting wound infla.ma.ory cells during the first 24 hours a.ter surgery. The results of the differentia. count were computerized by using a.tificia. neura. network for obta.ning wound infla.ma.ory cell node (WICN). The pa.ients were followed up for sixteen yea.s or to the dea.h. WICN va.ues were compa.ed with the pa.ients’ surviva.. Results: WICN reflects surviva. better tha. a.y single type of wound infla.ma.ory cells a.one (HR = 3.1;p = 0.081 for low/high WICN a. 10 yea. surviva.). From severa. clinica. cha.a.teristics dia.etes only predicted shorter surviva. time (HR = 5.5;p = 0.014 for 10 yea. surviva.) better tha. WICN. Conclusion: These results support the view tha. regula.ly timed cell-to-cell ra.ios in wound infla.ma.ion, most often seen a. high WICN, reflect beneficia. surviva.. Instea., a.erra.t counts of infla.ma.ory cells in the wounds lea. to low WICN a.d often to the pa.ients’ shorter surviva..
