Human serum (HS) has been reported to induce aggregation of human eyelid adipose-derived stem cells (HEACs) during high-density culture in vitro. The present study focused on the role of cell adhesion molecules and gelatinases during HS-induced aggregation of HEACs. HS-induced aggregation occurred between 9-15 days of culture. Cells aggregated by HS medium (HS-agg) showed stronger expression of...

A sudden elevation in temperature triggers a stress response found in all organisms that brings about a global transition in gene expression. Typically, the expression of most genes is either shut down or greatly attenuated, and a specific group of genes, called heat shock (HS) genes, is rapidly induced to high levels (Schlesinger et al., 1982). Proteins encoded by HS genes enable cells to surv...

Glycosaminoglycans (GAGs) play important roles on the regulation of extracellular signaling, neuronal development, and cartilage maintenance. The extracellular concentration of total GAGs has been used as an established measure for the diagnosis of mucopolysaccharidoses (MPSs). Heparan sulfate (HS), Dermatan sulfate (DS) and chondroitin sulfate are known to be elevated in the GAGs under patholo...

Let Hs,t1,…,tk be the graph with s triangles and k odd cycles of lengths t1,…,tk?5 intersecting in exactly one common vertex. Recently, Hou et al. (2018) [27], Yuan [42] determined independently maximum number edges an n-vertex that does not contain as a subgraph. In this paper, we determine graphs order n attain spectral radius among all containing no for large enough.

A hybrid metaheuristic approach by hybridizing harmony search (HS) and firefly algorithm (FA), namely, HS/FA, is proposed to solve function optimization. In HS/FA, the exploration of HS and the exploitation of FA are fully exerted, so HS/FA has a faster convergence speed than HS and FA. Also, top fireflies scheme is introduced to reduce running time, and HS is utilized to mutate between firefli...

In the last years, model checking with interval temporal logics is emerging as a viable alternative to model checking with standard point-based temporal logics, such as LTL, CTL, CTL∗, and the like. The behavior of the system is modelled by means of (finite) Kripke structures, as usual. However, while temporal logics which are interpreted “point-wise” describe how the system evolves state-by-st...

T he remarkable long-distance sexual communication system of moths has fascinated and puzzled biologists and chemists since bombykol was identified and the term “pheromone” was coined 51 years ago. The pheromone signal is a bouquet of volatile chemicals wafting through the night air, synthesized and released by the female’s pheromone gland and detected and decoded by the male’s antenna and cent...

Hibiscus syriacus, a woody ornamental plant with great economic value, is vulnerable to salinity. Hence, its cultivation in saline areas severely restricted. Although grafting H. syriacus onto hamabo rootstock can greatly improve syriacus’s salt resistance, the photosynthetic response of and stress remains largely unknown. To address this question, self-rooted (Hs), self-grafted (Hs/Hs), hamabo...

Foi desenvolvida uma metodologia para quantificar compostos dialquilmercúricos usando Microextração em Fase Sólida em Headspace (HS-SPME) e Cromatografia Gasosa com Detecção por Emissão Atômica (GC-AED). Os parâmetros para detecção de Hg foram otimizados usando planejamento fatorial e superfícies de resposta. Experimentos univariados foram empregados para determinar as condições de HS-SPME; as ...
