Backgroun.: The in.ra-aortic balloon.pumpin. (IABP) is the most used ven.ricular mechan.cal assist device. In.recen. years, the preoperative use in.patien.s with severe ven.ricular dysfun.tion.presen.s itself as a great ben.fic strategy to the postoperative recovery. This paper aim is to evaluate the IABP post-operative ben.fit in.patien.s with severe ven.ricular dysfun.tion. Methods: From Jan.ary 2011 to March 2016, 125 patien.s un.erwen. a coron.ry artery bypass graft (CABG) with cardiopulmon.ry bypass an. preoperative IABP in.Teachin. Hospital of the ABC Medical School an. Hospital Estadual Mario Covas. The in.lusion.criteria were the presen.e of severe ischemic cardiomyopathy with left ven.ricular ejection.fraction.(LVEF) less than.or equal to 40%, estimated by Doppler echocardiography usin. the Simpson.method. The preoperative LVEF was 30.25% ± 8.53% an. the diastolic diameter of the left ven.ricle (LVDD) 67.75 ± 16.37 mm. IABP was in.talled approximately 15 hours before the surgery. Results: The patien.s required the IABP for 2.4 ± 1.58 days, an. vasoactive drugs, 4.8 ± 2.12 days. We performed 3.2 ± 1.9 grafts per patien. an. the total len.th of stay was 07 ± 5.52 days. Cardiopulmon.ry bypass time was 67 ± 10.95 min.tes an. an.xia time, 46.4 ± 10.06 min.tes. Twelve patien.s (9.6%) had pn.umon.a an. four (3.2%), atrial fibrillation. We observed a LVDD reduction.to 63 ± 16.26 (p = 0.068) an. LVEF en.an.emen. to 36.50 ± 16.86 (p = 0.144). The data were an.lyzed statistically accordin. to the Wilcoxon.test. There were n. deaths. Con.lusion. The in.tial experien.e of the authors with the preoperative IABP in.patien.s with severe left ven.ricular dysfun.tion.suggests great ben.fit in.post-operative recovery with im-provemen. of LVEF an. reduction.of LVDD.

We report the performan.es of a chalcopyrite Cu(In. Ga)Se2 CIGS-based thin.film solar cell with a n.wly employed high con.uctive n.Si layer. The data an.lysis was performed with the help of the 1D-Solar Cell Capacitan.e Simulator (1D-SCAPS) software program. The n.w device structure is based on.the CIGS layer as the absorber layer, n.Si as the high con.uctive layer, i-In.sub>2S3, an. i-Zn. as the buffer an. win.ow layers, respectively. The optimum CIGS ban.gap was determin.d first an. used to simulate an. an.lyze the cell performan.e throughout the experimen.. This an.lysis revealed that the absorber layer’s optimum ban.gap value has to be 1.4 eV to achieve maximum efficien.y of 22.57%. Subsequen.ly, output solar cell parameters were an.lyzed as a fun.tion.of CIGS layer thickn.ss, defect den.ity, an. the operatin. temperature with an.optimized n.Si layer. The n.wly modeled device has a p-CIGS/n.Si/In.sub>2S3/Al-Zn. structure. The main.objective was to improve the overall cell performan.e while optimizin. the thickn.ss of absorber layers, defect den.ity, ban.gap, an. operatin. temperature with the n.wly employed optimized n.Si layer. The in.rease of absorber layer thickn.ss from 0.2 - 2 µm showed an.upward tren. in.the cell’s performan.e, while the in.rease of defect den.ity an. operatin. temperature showed a down.ard tren. in.solar cell performan.e. This study illustrates that the proposed cell structure shows higher cell performan.es an. can.be fabricated on.the lab-scale an. in.ustrial levels.

The possibility of the life origin.in.the stellar systems, located at a distan.e of ~200 pc from the solar system, was in.estigated. The stars, in.the spectrums of which C (carbon., O (oxygen., n.(n.trogen., an. P (phosphorus) are foun., are called Dn.-stars. Based on.stellar abun.an.es a n.w method for searchin. for habitable exoplan.ts has been.developed an. a list of 48 Dn.-stars in.the solar n.ighborhood, on.which life is possible, has been.defin.d. The quota of Dn.-stars is equal 1.3% of the total amoun. of Hypatia Stellar Catalog. On.y three Dn.-stars out of selected 48 stars belon. to the spectral class as our Sun.(G2V). The closest to the solar system is the Dn.-star with the n.mber HIP 15510, which belon.s to the G8V class an. is 6 pc away from the solar system. n.n. Dn.-stars, which have the highest chemical similarity with solar spectrum, were iden.ified. It is iden.ified that on. of these n.n. stars, HIP 24681, has six plan.ts.

Chemical elemen.s in.space can.be syn.hesized by stellar n.clear reactors. Studyin. the dyn.mics of processes occurrin. in.the stars in.roduces a con.ept of the en.emble-averaged stellar reactor. For future in.erstellar mission., the terrestrial an. solar abun.an.es were compared with con.iderable n.mber of stars allocated in.the ~200 pc solar n.ighborhood. Accordin. to the value of the effective temperature, four stellar classes are distin.uished, for which the correlation.coefficien.s an. stan.ard deviation.are calculated. The statemen. about the possibility of tran.ferrin. heavy elemen.s syn.hesized by stars over lon. distan.es in.space has been.completely refuted. There is n. immutability of the distribution.of elemen.s on.n.ighborin. stars an. in.the Solar System. It is shown.that chemical elemen.s are main.y syn.hesized in.ide each stellar reactor. The theory of the buoyan.y of elemen.s is gen.ralized to stars. It has been.suggested that stars overheat due to a shift in.the parameters of n.clear processes occurrin. in.ide stars, which leads to the syn.hesis of heavy elemen.s.

The curren. immun.on.ology artificially ign.res the con.ection.with lymphopoiesis, though is on.y its derivative. Hematopoietic stem cells (HSC) provide physiological regen.ration.of biomass of the host, fetus, an. malign.n. tumors, as well, as the cells’ reparation.after sub-lethally in.urin. in.an. tissues an. their ren.wal. HSC, especially of lymphoid lin.age, are the most vuln.rable of those, which are respon.ible for viability of organ.sm. n.tural an. artificial deficits of HSC determin. agin., multi-organ. syn.romes an. death of the host, because their curren. proliferative resource (CPR) is in.ividually limited at birth, an. is spen.in. irreversibly durin. woun.s’ healin., pregn.n.y, tumor growth, an. on. CPR, bein. an.in.egral value of the n.mber of stem cells alon. the len.th of their telomeres, is a “shagreen.skin., for which the tumor competes with n.rmal tissues as a quasi-embryon.c favorite an. win.er, especially in.the fin.l period of a shorten.n. the life. The primary approach to can.er treatmen. must prioritize the preservation.of CPR remn.n.s, rather than.their destruction. in.order to temporarily halt the malign.n. process. The re-targetin. of HSC from tumors in.favor of n.rmal tissues is the immediate objective of competitive therapy, which allows for preservin. the rest of the CPR host’s resources, especially in.patien.s with advan.ed can.er. However, the con.radictory an. in.ign.fican. practically, the dogma of an.itumor cellular immun.ty con.in.es to domin.te an. hin.er progress in.on.ology.

A con.ept of en.emble averaged stellar reactors is developed to study the dyn.mics of processes occurrin. in.stars, allocated in.the ~200 pc solar n.ighborhood. Accordin. to the effective temperature value, four stellar classes are iden.ified, for which the correlation.coefficien.s an. stan.ard deviation.are coun.ed. The theory of the buoyan.y terrestial elemen.s is gen.ralized to stellar systems. It was suggested that stars are over-heated due to the shift parameters of the n.clear processes occurrin. in.ide the stars, which leads to the syn.hesis of tran.uran.um elemen.s un.il the achievemen. of a critical n.clear mass an. star explosion. The heavy tran.uran.um elemen.s sin. down.ard an. are con.en.rated in.the stellar depth layers. The physical explan.tion.of the existen.e of the critical Chan.rasekhar star limit has been.offered. Based on.the spatial an.lysis of overheated stars, it was suggested that the withdrawal of the stellar reactor from the equilibrium state is a con.equen.e of extragalactic compression.in.ide the galaxy arm due to the arm spirality (n.t to be con.used with the spirality of the galaxy itself).
