Abstract Background Age-dependent accumulation of lipofuscin in the retinal pigment epithelium (RPE) is closely related to etiology autosomal recessive Stargardt’s disease (STGD1) and dry age-related macular degeneration (AMD). N -retinylidene- -retinylethanolamine (A2E) a leading component RPE that highly susceptible blue light. Ferroptosis an iron-dependent form non-apoptotic cell death characterized by lipid peroxides lethal level, which plays important role diseases. However, it remains...

In this paper, we give a classification of all compact Hermitian manifolds with flat Bismut connection. We show that the torsion tensor such manifold must be parallel, thus universal cover is Lie group equipped bi-invariant metric and compatible left invariant complex structure. particular, isosceles Hopf surfaces are only non-Kähler surfaces, while central Calabi-Eckmann threefolds simply-connected threefolds.

With globalization, countries are more connected than before by trading flows, which amounts to at least trillion dollars today. Interestingly, around percents of exports consist intermediate products in global. Therefore, the trade flow network particular product with high added values can be regarded as value chains. The problem is weather we discriminate between these from their unique structure? This paper applies analysis method developed ecology 638 networks different products. We...

Age-related macular degeneration (AMD) is a common disease contributing to vision loss in the elderly. All-trans-retinal (atRAL) retinoid retina, and its abnormal accumulation exhibits toxicity retina promotes oxidative stress-induced photoreceptor degeneration, which plays crucial role AMD progression. Crocin natural product extracted from saffron, displays significant antioxidant anti-inflammatory effects. The present study elucidates protective effects of crocin on cell damage by atRAL...

We construct complete gradient Kähler–Ricci solitons of various types on the total spaces certain holomorphic line bundles over compact Kähler–Einstein manifolds with positive scalar curvature. Those are noncompact analogues examples found by Koiso [On rotationally symmetric Hamilton's equations for metrics, in Recent Topics Differential and Analytic Geometry, Advanced Studies Pure Mathematics, Vol. 18-I (Academic Press, Boston, MA, 1990), pp. 327–337]. Our can be viewed a generalization...

This paper is the first step in a systematic project to study examples of Kähler manifolds with positive holomorphic sectional curvature (H>0). Hitchin proved that any compact surface H>0 must be rational and he constructed such on Hirzebruch surfaces M 2,k =ℙ(H k ⊕1 ℂℙ 1 ). We generalize Hitchin’s construction prove manifold n,k n-1 ) admits metric each its classes. demonstrate pinching behaviors curvatures new differ from those which were studied recent work Alvarez–Chaturvedi–Heier. Some...

In this short paper we observe that a recent result of C.-W. Chen meshes well with earlier work H.-D. Cao and D.-T. Zhou, O. Munteanu, J. Carrillo L. Ni, S.-J. Zhang. We give necessary sufficient condition for complete noncompact shrinking gradient Ricci solitons to have positive asymptotic volume ratio.

In this study, the complete mitogenome sequence of great seahorse Hippocampus kelloggi (Gasterosteiformes: Syngnathidae) has been amplified and sequenced employing polymerase chain reaction-based method. The total length mitochondrial DNA is 16 536 bp includes 13 protein-coding genes, two ribosomal RNA, 22 transfer RNA a control region. gene arrangement H. was similar to that observed in most vertebrate creatures. overall base composition 32.19% for A, 23.68% C, 29.30% T, 14.82% G, with...

By extending Koiso's examples to the non-compact case, we construct complete gradient Kahler-Ricci solitons of various types on certain holomorphic line bundles over compact Kahler-Einstein manifolds. Moreover, a uniformization result steady with non-negative Ricci curvature is obtained under additional assumptions.

Abstract Doxorubicin (DOX) is a broad-spectrum anti-tumor drug, but its clinical application greatly limited because of the cardiotoxicity. Thus, exploration effective therapies against DOX-induced cardiotoxicity necessary. The aim this study to investigate effects and possible mechanisms Trametes Sanguinea Lyoyd fermented crude polysaccharide (TSLFACP) We investigated protective TSLFACP on myocardial injury using two in vitro cells DOX-treated cardiomyocytes H9C2 embryonic cell line...

The mountain weasel (Mustela altaica) belongs to family Mustelidae, which is the near threatened species in IUCN Red List. In this study, complete mitochondrial genome of M. altaica was sequenced and characterized. 16,521 bases length (GenBank accession no. KC815122). nucleotide sequence data 12 heavy-strand protein-coding genes other 20 Mustelidae were used for phylogenetic analyses. Trees constructed by using Bayesian inference, maximum parsimony likelihood demonstrated that close Mustela...
