The HIF1A Functional Genetic Polymorphism at Locus +1772 Associates with Progre...

The hypoxia inducible factor 1 alpha (HIF1a) is a key regulator of tumour cell response to hypoxia, orchestrating mechanisms known to be involved in cancer aggressiveness and metastatic behaviour. In this study we sought to evaluate the association of a functional genetic polymorphism in HIF1A with overall and metastatic prostate cancer (PCa) risk and with response to androgen deprivation therapy (ADT). The HIF...

Índice Proliferativo Ki-67 no Cancro Gástrico

Introdução: O cancro gástrico representa ainda uma das principais causas de mortalidade por doença oncológica a nível mundial, apesar da evolução substancial no seu tratamento. Diversos marcadores biológicos têm sido introduzidos com intuito prognóstico da doença. A proteína Ki-67 através de técnicas imunocitoquímicas tem sido utilizada como um indicador da actividade proliferativa tumoral. No cancro gástrico o...

Hospital Resource Utilization and Treatment Cost of Skeletal-Related Events in ...

BACKGROUND: Skeletal-related events (SREs) occur frequently in patients with bone metastases as a result of breast (BC) and prostate (PC) cancers. They increase both morbidity and mortality and lead to extensive health-care resource utilization. METHODS: Health care resource utilization by BC/PC patients with at least one SRE during the preceding 12 months was assessed through retrospective chart review. SRE-tr...

Solid-state electrochromic devices using pTMC/PEO blends as polymer electrolytes

Flexible, transparent and self-supporting electrolyte films based on poly(trimethylene carbonate)/poly(ethylene oxide) ((p(TMC)/PEO) interpenetrating networks doped with LiClO4 were prepared by the solvent casting technique. These novel solid polymer electrolyte (SPE) systems were characterized by measurements of conductivity, cyclic voltammetry, differential scanning calorimetry and thermogravimetry. The incor...

Energetics and Dynamics of Naphthalene Polyaminic Derivatives. Influence of Str...

Two new fluorescent macrocyclic structures bearing two naphthalene (Np) units at both ends of a cyclic polyaminic chain were investigated with potentiometric, fluorescence (steady-state and time-resolved) and laser flash photolysis techniques. The fluorescence emission studies show the presence of an excimer species whose formation depends on the protonation state of the polyamine chains implying the existence ...
