Keratinocyte growth factor and the expression of wound-healing-related genes in primary human keratinocytes from burn patients

Acta cir. bras; 31 (8), 2016
ABSTRACT PURPOSE: To evaluate the effect of keratinocyte growth factor (KGF) treatment on the expression of wound-healing-related genes in cultured keratinocytes from burn patients. METHODS: Keratinocytes were cultured and divided into 4 groups (n=4 in each group): TKB (KGF-treated keratinocytes from b...

Effects of insulin-like growth factor-1 on random pattern skin flap survival in rats

Acta cir. bras; 31 (8), 2016
ABSTRACT PURPOSE: To investigate the effects of pharmacological delay with insulin-like growth factor-1 (IGF-1) on skin flap survival. METHODS: Thirty Sprague-Dawley rats were submitted to dorsal skin flap (3x9 cm). Seven days before the surgery, the animals were subdivided into three groups of 10 rats...

Animals were gavaged for 4 weeks with saline, sesame oil (0.5, 1, or 2 mL/k...

First report of TEM-104-, SHV-99-, SHV-108-, and SHV-110-producing Klebsiella pneumoniae from Iran

Abstract: INTRODUCTION: Extended-spectrum beta-lactamases (ESBLs) are bacterial enzymes capable of hydrolyzing beta-lactams. The aim of this study was to describe the prevalence of TEM- and SHV-type ESBL-producing Klebsiella pneumoniae strains in Zahedan, Southeast Iran. METHODS: A total of 170 non-rep...

The role of the genetic elements bla oxa and IS Aba 1 in the Acinetobacter calcoaceticus-Acinetobacter baumannii complex in carbapenem resistance in the hospital setting

Abstract: INTRODUCTION: Members of the Acinetobacter genus are key pathogens that cause healthcare-associated infections, and they tend to spread and develop new antibiotic resistance mechanisms. Oxacillinases are primarily responsible for resistance to carbapenem antibiotics. Higher rates of carbapene...

Citronellal-induced disruption of membrane homeostasis in candida albicans and attenuation of its virulence attributes

Abstract: INTRODUCTION There is an increasing burden of multidrug resistance. As a result, deciphering the mechanisms of action of natural compounds with antifungal activity has gained considerable prominence. We aimed to elucidate the probable mechanism of action of citronellal, a monoterpenoid found ...

A modified method by differential adhesion for enrichment of bladder cancer stem cells

Int. braz. j. urol; 42 (4), 2016
ABSTRACT Purpose: In a previous study the vaccine was effective against bladder cancer in a mouse model. However, a small portion of tumors regrew because the vaccine could not eliminate bladder cancer stem cells (CSCs). In this study, we showed a modified method for the isolation of bladder CSCs using ...
