Abstract Excessive generation of mitochondrial reactive oxygen species (ROS) is considered to be initiating event in the development diabetic nephropathy (DN). Mitochondrial biosynthesis mediated by coactivator PGC‐1α and its downstream transcription factors NRF1 TFAM may a key target maintaining function. Resveratrol (RESV), natural polyphenolic antioxidant, potent SIRT1 agonist. In this study we established diabetes mouse podocyte exposed high glucose as vivo vitro models investigate...

With the rapid growth of video resources on online education platforms, accurately recommending that meet learners’ needs has become crucial. This paper proposes a personalized resource recommendation model based social tags, aiming to address challenges cold start and data sparsity, thereby enhancing prediction accuracy platforms. The generates tags by analyzing descriptive information, user annotations, comments associated with videos, constructs dynamic learner profiles. similarity...

Abstract Let ( be two positive integers. We generalize the well‐studied notions of ‐colorings and circular chromatic number to signed graphs. This implies a new notion colorings graphs, corresponding χ. Some basic facts on graphs are proved, differences results unsigned analyzed. In particular, we show that difference between graph is at most 1. Indeed, there where On other hand, for n vertices, if smaller than 1, then exists , such . also equivalent r (see [12] (X. Zhu, Recent developments...

Water conservation is an important function of forest ecosystems, but it still unclear which types best in this regard. We investigated the water indicators including water-holding rate branches and leaves (BLwr), capacity litter (Lwc), absorption (Lwr), soil infiltration (Ir), content (SWC), storage (SWS), organic matter (SOM) accumulation five (Larix gmelinii forests, Pinus koraiensis Robinia pseudoacacia tabulaeformis mixed forests) evaluated them using gray correlation method (GCM). The...

The aim of the present study was to investigate effects transcription factor EB (TFEB) overexpression on oxidative stress, mitochondrial function and apoptosis in podocytes induced with high glucose. High glucose‑induced time‑dependent changes TFEB expression were identified nuclear translocation observed podocytes. Overexpression markedly reduced stress podocytes, increased superoxide dismutase 2 heme oxygenase 1 antioxidant enzymes. It further that could partially restore peroxisome...

The objective of the present study was to provide a basis for personalized treatment intermediate and advanced hepatic alveolar echinococcosis (HAE) by elucidating characteristics vascular invasion lesion growth. A total 160 patients with HAE who were subjected plain as well contrast‑enhanced 3.0‑T magnetic resonance imaging prior surgery analyzed. Pathological intra‑operative observations subjects also considered. size location lesions, growth patterns assessed. 78 (48.75%) had lesions...

Steinberg's conjecture states that planar graphs without 4- and 5-cycles are 3-colorable. This conjecture, though disproved recently, has motivated a lot of work in the literature. A plane graph is $G$ together with an embedding into Euclidean plane. 7-cycle $C$ ext-triangular if it adjacent to triangle $T$ such areas inside have no intersection. In this paper, we prove 3-colorable they contain 7-cycles, which improves number known results. particular, our result implies (1) 4-, 5-, 7-cycles...

Abstract This paper proves that every planar graph having no cycle of length 4, 7, or 9 is DP‐3‐colorable.

The concept of DP-coloring graphs was introduced by Dvo\v{r}\'{a}k and Postle, used to prove that planar without cycles length from $4$ $8$ are $3$-choosable. In the same paper, they proposed a more natural stronger claim such DP-$3$-colorable. This paper confirms proving result having no cycle $4$, $6$ or DP-3-colorable.

A graph $G$ is $(d_1,d_2,d_3)$-colorable if the vertex set $V(G)$ can be partitioned into three subsets $V_1,V_2$ and $V_3$ such that for $i\in\{1,2,3\}$, induced $G[V_i]$ has maximum vertex-degree at most $d_i$. So, $(0,0,0)$-colorability exactly 3-colorability. The well-known Steinberg's conjecture states every planar without cycles of length 4 or 5 3-colorable. As this being disproved by Cohen-Addad etc. in 2017, a similar question, whether $i$ 3-colorable given $i\in \{6,\ldots,9\}$,...

Let $k, d$ ($2d \leq k)$ be two positive integers. We generalize the well studied notions of $(k,d)$-colorings and circular chromatic number $\chi_c$ to signed graphs. This implies a new notion colorings graphs, corresponding $\chi$. Some basic facts on graphs are proved, differences results unsigned analyzed. In particular, we show that difference between graph is at most 1. Indeed, there where On other hand, for $n$ vertices, if smaller than 1, then exists $\epsilon_n>0$, such $1 -...

This paper studies the choosability of signed planar graphs. We prove that every graph is 5-choosable and there a which not 4-choosable while unsigned 4-choosable. For each $k \in \{3,4,5,6\}$, without circuits length $k$ Furthermore, 3 4 3-choosable. construct with girth 3-choosable but

The only remaining case of a well known conjecture Vizing states that there is no planar graph with maximum degree 6 and edge chromatic number 7. We introduce parameters for graphs, based on the degrees faces, study question whether are upper bounds these edge-chromatic critical graphs. Our results provide smallest counterexamples to Vizing's conjecture, thus providing partial characterization such if they exist.For $k \leq 5$ give insights into structure

To assess the value of MRI combined with serum ferritin analysis in measurement hepatic iron deposition among patients alveolar echinococcosis.A total 96 definitive diagnosis echinococcosis and 30 healthy volunteers were enrolled underwent routine 1.5T MR scanning, all laboratory examination data captured. The liver-to-muscle signal intensity ratio, level liver functions analyzed.The ratio was (1.95 ± 0.57) (2.22 0.28) (t = 2.022, P < 0.05), negatively associated (rs -0.446, 0.01).Abnormal...
