report on page 639 identifies a family of proteins that are important when worms are unable to deal with ER stress. The results from Urano et al. suggest that these proteins are receptors for incorrectly folded proteins at the ER. In worms and other eukaryotes, conditions that stress the ER, such as those that inhibit glycosylation, activate the unfolded protein response (UPR). The UPR comprise...

The severity of urinary tract infection (UTI) reflects the quality and magnitude of the host response. While strong local and systemic innate immune activation occurs in patients with acute pyelonephritis, the response to asymptomatic bacteriuria (ABU) is low. The immune response repertoire in ABU has not been characterized, due to the inherent problem to distinguish bacterial differences from ...

Abstract The health of Corymbia calophylla (marri), a keystone tree species in the native forests southwest Western Australia, has been decline for past few decades. Phytophthora root disease and waterlogging have often cited as contributing to this decline. Traditional methods (i.e., field surveys sampling) mapping infection are time-consuming expensive; thus, potential reflectance spectroscop...

Escherichia coli is the most common organism associated with asymptomatic bacteriuria (ABU) in humans. In contrast to uropathogenic E. coli (UPEC) that cause symptomatic urinary tract infection, very little is known about the mechanisms by which these strains colonize the urinary tract. Here, we have investigated the biofilm-forming capacity on abiotic surfaces of groups of ABU strains and UPEC...

Introduction During the process photodynamic therapy (PDT), bleaching of photosensitizer induced by irradiation and generation of reactive oxygen species (ROS) can provide some information concerning the efficiency of treatment. Since gold nanoparticles (GNPs) have been highlighted as efficient drug delivery systems, in this study, by utilizing GNPs conjugated with 5 aminolevulinic acid (5-ALA-...

photodynamic therapy (pdt) using 5-aminolevulinic acid (5-ala)-induced protoporphyrin ix (ppix) has been considered as a new method for treating neoplasms. however, ala-pdt is suboptimal for thick tumors. searching for new approaches, we investigated the effect of adding differentiation therapy (dt) with vitamin e succinate (ves) to pdt in human prostate ln-cap-fgc10 cancer cells in vitro . the...

The endoplasmic reticulum stress response, also known as the unfolded protein response (UPR), has been implicated in the normal physiology of immune defense and in several disorders, including diabetes, cancer, and neurodegenerative disease. Here, we show that the apoptotic receptor CED-1 and a network of PQN/ABU proteins involved in a noncanonical UPR response are required for proper defense t...

Introduction: In recent years, bismuth-based nanomaterials have been widely used in medical researches as imaging, drug delivery and x-ray radiosensitizing agents. Due to their anti-microbial effects against Helicobacter pylori (HP), bismuth colloidal compounds are used to treat various types of diseases such as chronic gastritis. Despite their advantages, bismuth-based compoun...
