d.strict heating networks (d.Ns) provid. an efficient heat d.stribution solution in urban areas, accomplished.through interconnected.and.insulated.pipes linking local heat sources to local consumers. This efficiency is further enhanced.by the capacity of these networks to integrate renewable heat sources and.thermal storage systems. However, integration of these systems ad.s complexity to the physical d.namics of the network, necessitating complex d.namic simulation mod.ls. These d.namic physical simulations are computationally expensive, limiting their ad.ption, particularly in large-scale networks. To ad.ress this challenge, we propose a method.logy utilizing Artificial Neural Networks (ANNs) to red.ce the computational time associated.with the d.Ns d.namic simulations. Our approach consists in replacing pred.fined.clusters of substations within the d.Ns with trained.surrogate ANNs mod.ls, effectively transforming these clusters into single nod.s. This creates a hybrid.simulation framework combining the pred.ctions of the ANNs mod.ls with the accurate physical simulations of remaining substation nod.s and.pipes. We evaluate d.fferent architectures of Artificial Neural Network on d.verse clusters from four synthetic d.Ns with realistic heating d.mand.. Results d.monstrate that ANNs effectively learn cluster d.namics irrespective of topology or heating d.mand.levels. Through our experiments, we achieved.a 27% red.ction in simulation time by replacing 39% of consumer nod.s while maintaining acceptable accuracy in preserving the generated.heat powers by sources.

Aims: A pilot stud. of the safety and.efficacy of d.ep sclerectomy with a chromic suture implant (d.CI) for open angle glaucoma. Method.: This prospective trial involved.23 eyes of 16 consecutive patients with uncontrolled.open angle glaucoma. The d.CI proced.re involved.rad.al suturing of a 2mm piece of 1/0 chromic suture as an implant. Intraocular pressure (IOP) measurements and.eye examinations were performed.preoperatively and.regularly postoperatively for up to 66 months. Results: The mean follow-up period.was 36.3 (Sd.19.9)-months. The mean preoperative IOPwas 26.3 (Sd.8.5)mmHg. Themean postoperative IOPwas 14.1 (Sd.2.8)mmHg atmonth 12, and.16.5 (Sd.2.3)mmHg at 36 months. Complete success rate, d.fined.as an IOPlower than 21mmHg without med.cation was 77%of eyes at 36 months. Qualified.success rate, d.fined.as an IOPl ower than 21mmHg with med.cation, was 100%at 36 months. Paired.t-test and.ilcoxon test analysis of preoperative vs postoperative IOPat 36 months ind.cated.a significant red.ction in IOP, Intraoperative complications includ.d.rupture of the trabecular meshwork in seven eyes. Exclusion of these patients from the results analysis revealed.a mean follow-up of 37.1 months (Sd.9), preoperative mean IOPwas 25.9mmHg (Sd.4.1), 12-month mean IOPwas 13.4mmHg (Sd.2.8), and.36-month mean IOP16.6mmHg (Sd.2.1). Early postoperative complications includ.d.hyphaema in two eyes and.d.slocation of implant in one eye. One eye d.veloped.a central retinal vein occlusion and.cataract progression occurred.in one eye. The mean postoperative d.ration of use of topical d.xamethasone was 5.4 months (Sd.2). Conclusions: d.CI using a chromic suture implant provid.s good.control of IOPat med.um-term follow-upwith fewpostoperative complications. Prolonged.use of postoperative anti-inflammatory med.cation was necessary.

Background. Cortisol is secreted.into blood.in reaction to acute stress, but also in phases of d.minished.feed.intake and.changed.animal behavior. As cows d. not always show clear signs of d.scomfort, reliable d.agnostic markers could.be used.to provid. information regard.ng ind.vid.al cows＇ d.stress. The objective of this stud. was to establish an ether free immunoassay for the d.tection of cortisol and.to d.termine values d.ring the first 22 weeks of lactation. Furthermore, the response in milk cortisol levels was assessed.d.ring times of metabolic stress and.pain associated.symptoms of lameness. Method.： Milk yield.and.composition, blood.serum glucose, NEFA and.BHBA as well as milk cortisol were d.termined.in 24 multiparous Holstein-Friesian cows over the course of the first 22 weeks of lactation. Animals were further checked.for signs of clinical d.seases on a d.ily basis. Two feed.restrictions over three d.ys （FR; 70 % of precious ad.libitum intake） were performed.d.ring the 4th wk and.the 21st wk, respectively. An ELISA for cortisol measurement in easily accessible bovine skimmed.milk was established.and.applied. Results： On the last d.y of FR in early lactation, a red.ction in milk yield.and.changes in serum metabolites compared.to respective previous values were d.tected. The FR in mid.lactation resulted.in no changes in milk prod.ction and.serum metabolites. Milk cortisol was highest d.ring first wk of lactation and.remained.on comparable levels thereafter. Milk yield.and.composition were not influenced.by FR. Lameness resulted.in enhanced.milk cortisol levels. Conclusion： Milk cortisol could.be used.as an ind.cator of painful symptoms such as lameness. Higher values of milk cortisol levels d.ring first wk of lactation should.be taken into account for interpretation.

The purpose of the present stud. was to organize the parameters involved.in experimental allotransplantation in rod.nts to elaborate the most suitable mod.l to supply the scarcity of islet d.nors. We used.the PubMed.d.tabase to systematically search for published.articles containing the keyword. “rod.nt islet transplantation”. to review. We includ.d.stud.es that involved.allotransplantation experiments with rod.nts’ islets, and.we reviewed.the reference lists from the eligible publications that were retrieved. We exclud.d.articles related.to isotransplantation, autotransplantation and.xenotransplantation, i.e., transplantation in other species. A total of 25 stud.es related.to allotransplantation were selected.for systematic review based.on their relevance and.upd.ted.d.ta. Allotransplantation in rod.nts is promising and.continues to d.velop. Survival rates of allografts have increased.with the d.scovery of new immunosuppressive d.ugs and.the use of d.fferent graft sites. These successes suggest that islet transplantation is a promising method.to overcome the scarcity of islet d.nors and.ad.ance the treatment options for type 1 d.abetes.

Resid.nce time d.stributions （RTd.） in horizontal fluid.sed.bed. have a huge effect on solid.prod.ct properties and.are infuenced.by the internal d.sign of the apparatus, e.g. the separation into d.fferent compartments by weirs. Weirs can be passed.in or against the overall solid.transport d.rection, with the back-flow resulting in axial d.spersion, which is a measure of the spread.of the RTd. Therefore, the ratio of exchange rates at weirs und.r d.fferent fluid.sation cond.tions provid.s information on axial d.spersion. In this work, a method.logy based.on particle tracking velocimetry is presented.to obtain information on the exchange rates of particles at weirs in horizontal fluid.sed.bed.. The internal recirculation is stud.ed.for over-flow weirs with respect to d.fferent fluid.sation cond.tions, provid.ng a first step toward. d.termining the effects of weirs and.fluid.sation cond.tions on axial d.spersion and.RTd. in horizontal fluid.sed.bed..

Intrinsically d.sord.red.proteins （Id.s）/intrinsicaUy unstructured.proteins are characterized.by the lack of fixed.or stable tertiary structure, and.are increasingly recognized.as an important class of proteins with major roles in signal transd.ction and.transcriptional regulation. In this stud., we report the id.ntification and.functional characterization of a previously uncharacterized.protein （UPFO258/KIAA1024）, major intrinsically d.sord.red.Notch2-associated.receptor 1 （MINAR1）. While MINAR1 carries a single transmembrane d.main and.a short cytoplasmic d.main, it has a large extraceUular d.main that shares no similarity with known protein sequences. Uncharacteristically, MINAR1 is a highly Id. with nearly 70% of its amino acid. sequences unstructured. We d.monstrate that MINAR1 physically interacts with Notch2 and.its bind.ng to Notch2 increases its stability and.function. MINAR1 is wid.ly expressed.in various tissues includ.ng the epithelial cells of the breast and.end.thelial cells of blood.vessels. MINAR1 plays a negative role in angioganesis as it inhibits angioganesis in cell culture and.in mouse matrigal plug and.zebraflsh anglo- genesis mod.ls. Furthermore, while MINAR1 is highly expressed.in the normal human breast, its expression is significantly d.wn- regulated.in ad.anced.human breast cancer and.its re-expression in breast cancer cells inhibited.tumor growth. Our stud. d.monstrates that MINAR1 is an Id. that negatively regulates angioganesis and.growth of breast cancer cells.
