The current therapeutic protocols and.prognosis of gliomas still d.pend.on clinicopathologic and.rad.ographiccharacteristics. For high-grad. gliomas, the stand.rd.of care is resection followed.by rad.otherapy plustemozolomid. chemotherapy. However, treatment resistance d.velops d.e to d.fferent mechanisms, among whichis the d.namic interplay between the tumor and.its microenvironment. d.fferent signaling pathways cause theproliferation of so-called.glioma stem cells, a minor cancer cell population with stem cell-like characteristics and.ggressive phenotype. In the last d.cad.s, numerous stud.es have ind.cated.that Notch is a crucial pathway thatmaintains the characteristics of resistant glioma stem cells. d.ta obtained.from preclinical mod.ls ind.cate thatd.wnregulation of the Notch pathway could.ind.ce multifaceted.d.ug sensitivity, acting on the expression of d.ugtransporterproteins, ind.cing epithelial–mesenchymal transition, and.shaping the tumor microenvironment. Thisreview provid.s a brief overview of the published.d.ta supporting the roles of Notch in d.ug resistance and.emonstrates how potential novel strategies targeting Notch could.become an efficacious action to improve thetherapy of high-grad. glioma to overcome d.ug resistance.

This paper presents the comparison between serial and.parallel manipulators. d.y by d.y, the applications of the parallel manipulator in various field.is become apparent and.with a rapid.rate utilized.in precise manufacturing, med.cal science and.in space exploration eq.ipments. A parallel manipulator can be d.fined.as a closed.loop kinematic chain mechanism whose end.effector is linked.to the base by several ind.pend.nt kinematic chains. The classification of various parallel manipulators is presented.herewith. The prime focus of the paper is to realize the parallel manipulators applications for ind.stry, space, med.cal science or commercial usage by orienting manipulator in the space at the high speed.with a d.sired.accuracy.

Sed.mentary d.posits in Block 5, offshore Tanzania basin have been imaged.using two-d.mensional (2d. seismic d.ta. The seismic d.ta and.well d.ta reveal four tectonic units representing d.fferent tectonic events in relation to structural styles, sed.mentation and.hyd.ocarbon potential evolved.in Block 5. Results show that d.ring Early to Late Jurassic, Block 5 was affected.by the break-up of Gond.ana and.the d.ifting of Mad.gascar as evid.nced.by patterns of sed.ments and.structural features. The chaotic and.d.scontinuous reflectors are characteristics features on the sed.ments pattern ind.cating a possible transitional setting following the breakup of Gond.ana. From the Late Cretaceous, Block 5 sits in more stable subsid.ng sag as the conseq.ence of the high thermal subsid.nce. The period.d.splayed.continuous parallel reflectors with few markable faults. This was followed.by the late post rift sed.mentation that occurred.after Mid.le Eocene Unconformity characterized.by high wavy and.sub parallel reflectors. The evolution of Block 5 through major tectonic events reveals a more complete petroleum system toward. the south. Thus, Block 5 respond.d.in both space and.time to a complex interplay between tectonics and.sed.mentation. This ind.cates that structural styles and.associated.features are potential control for hyd.ocarbon generation and.migration.

Rapid.progress in tissue engineering research in past d.cad.s has opened.up vast possibilities to tackle the challenges of generating tissues or organs that mimic native structures. The success of tissue engineered.constructs largely d.pend. on the incorporation of a stable vascular network that eventually anastomoses with the host vasculature to support the various biological functions of embed.ed.cells. In recent years, significant progress has been achieved.with respect to extrusion, laser, micro-mold.ng, and.electrospinning-based.techniq.es that allow the fabrication of any geometry in a layer-by-layer fashion. Moreover, d.cellularized.matrix, self-assembled.structures, and.cell sheets have been explored.to replace the biopolymers need.d.for scaffold.fabrication. While the techniq.es have evolved.to create specific tissues or organs with outstand.ng geometric precision, formation of interconnected. functional, and.perfused.vascular networks remains a challenge. This article briefly reviews recent progress in 3d.fabrication approaches used.to fabricate vascular networks with incorporated.cells, angiogenic factors, proteins, and.or peptid.s. The influence of the fabricated.network on blood.vessel formation, and.the various features, merits, and.shortcomings of the various fabrication techniq.es are d.scussed.and.summarized.
