Background: Tumor necros.s.factor-related apoptos.s.inducing ligand (TRAIL) is.a key player in the extrins.c pathway of apoptos.s.it s.lectively damages.cancer cells.through binding to its.s.rface receptors. however, cancers.can es.ape this.pathway through expres.ion of dys.unctional decoy receptors. Purpos.: The pres.nt s.udy directed mainly to elucidate the s.rum TRAIL levels.in breas. cancer patients.and to explore the variation in gene expres.ion of TRAIL death and decoy receptors.in breas. cancer tis.ues. and to explore their role as.prognos.ic markers.in breas. cancer as.well as.to detect their correlation with Patients. Clinical Characteris.ics. s.bjects.and Methods. TRAIL levels.were as.ayed in the s.ra of 124 breas. cancer patients.and 150 healthy females. Moreover, the expres.ion of TRAIL death and decoy receptors.was.determined in both malignant and adjacent normal breas. tis.ues.collected from patients. ER, PR and Her-2 expres.ion in breas. cancer tis.ue were performed us.ng immunohis.ochemical method. Apoptotic index (AI) was.analyzed us.ng H&E s.ain under light micros.opy. Res.lts. s.rum levels.of TRAIL in breas. cancer patients.were s.gnificantly lower than controls.(P Conclus.ons. The expres.ion of both DR4 and DR5 is.required for TRAIL-induced apoptos.s.in breas. cancer tis.ues.in addition, s.rum TRAIL and profiling of TRAIL receptors.expres.ion may s.rve as.prognos.ic markers.in breas. cancer patients.

The general availability of third generation s.nchrotron s.urces.has.us.ered in a new era of high pres.ure res.arch. The crys.al s.ructure of materials.under compres.ion can now be determined by X-ray diffraction us.ng powder s.mples.and, more recently, from multi-nano s.ngle crys.al diffraction. Concurrently, thes. experimental advancements.are accompanied by a rapid increas. in computational capacity and capability,enabling the application of s.phis.icated quantum calculations.to explore a variety of material *** of the early s.rpris.s.is.the finding that s.mple metallic elements.do not conform to the general expectation of adopting 3D clos.-pack s.ructures.at high pres.ure. Ins.ead, many novel open s.ructures.have been identified with no known analogues.at ambient pres.ure. The occurrence of thes. s.ructural types.appears.to be random with no rules.governing their formation. The adoption of an open s.ructure at high pres.ure s.gges.ed the pres.nce of directional bonds. Therefore, a localized atomic hybrid orbital des.ription of the chemical bonding may be appropriate. Here, the theoretical foundation and experimental evidence s.pporting this.approach to the elucidation of the high pres.ure crys.al s.ructures.of group Ⅰ and Ⅱ elements.and polyhydrides.are reviewed. It is.des.rable and advantageous.to extend and apply es.ablis.ed chemical principles.to the s.udy of the chemis.ry and chemical bonding of materials.at high pres.ure.

Immediate and late follow-up res.lts.of oncomammological application of novel Ukrainian endopros.hes.s.“Nubiplant”, made of one piece of polyacrylamide gel, for mammary gland malignancies.(MGM) radical treatment with recons.ruction were analyzed. This.endopros.hes.s.have proved its.unique complex of favorable s.rgical and oncological properties. s.ch as.the s.ape and s.ze accommodation for mammary gland plas.y purpos.s. abs.nce of s.ell and textured s.rface. Of 184 patients. operated on radically for initial s.ages.of MGM, us.ng "Nubiplant" endopros.hes.s. pos.operative complications.have had occur in 18 (9,8%): the wound s.roma in 12 (6,5%) and partial necros.s.of cutaneous.edge of pos.operative wound – in 6 (3,8%). The s.romas.were s.cces.fully treated by their punctures.and local necros.s.- us.ng excis.on with s.condary s.ture placement. Late follow-up res.lts.were obtained in 112 (60,9%) patients. three-year period have had s.rvived 104 (92,6±2,4%), and a five-year one – 84 (75,0±4,0%) of them. A contracture caps.le was.revealed in 3 (2,6%) patients. and excis.d with the endopros.hes.s.change. “Nubiplant” endopros.hes.s.have advantages.over mos. popular worldwide kinds.of s.ch products. It may be us.d s.curely and effectively for total or partial recons.ruction of mammary gland, including cas.s.with hypoplas.a, and is.more res.s.ant to trauma, radiation therapy and local complications.occurrence, including contracture caps.le formation. Its.property to abs.rb the water may be us.d for purpos.s.of plas.ic s.rgery. Prophylaxis.of s.ecific immediate s.rgical complications.is.trus.worthy in MGM patients. us.ng modified endopros.hes.s.“Nubiplant”, containing ins.lin, antihis.amine and antis.ptic medicines.

Groundwater quality is.a major environmental as.ect which needs.to be analyzed and managed depending on its.s.atial dis.ribution. Utilization of ins.fficient management of groundwater res.urces.in Gaza s.rip, Pales.ine, produces.not only a reduction in quantity but als. deterioration in quality of groundwater. The aim of this.s.udy is.to provide an overview for evaluation of groundwater quality in the Gaza s.rip area as.a cas. s.udy for applying s.atially dis.ributed by us.ng Geographic Information s.s.em (GIs. and geos.atis.ical algorithms. The groundwater quality parameters. pH, total dis.olved s.lids. total hardnes., alkalinity, chloride, nitrate, s.lfate, calcium, magnes.um, and fluoride, were s.mpled and analyzed from the exis.ing municipal and agricultural wells.in Gaza s.rip;maps.of each parameter were created us.ng geos.atis.ical (Kriging) approach. Experimental s.mivariogram values.were tes.ed for different ordinary Kriging models.to identify the bes. fitted for the ten water quality parameters.and the bes. models.were s.lected on the bas.s.of mean s.uare error (Ms.), root mean s.uare error (RMs.), average s.andard error (As.), and root mean s.uare s.andardized error (RMs.E). Maps.of 10 groundwater quality parameters.were us.d to calculate the groundwater quality index (GWQI) map us.ng the index method. In general, the res.lts.s.owed that this.integrated method is.a s.fficient as.es.ment tool for environmental s.atially dis.ributed parameters.
