BACKGROUND Ethanol production from lignocellulosic feedstocks (also known as 2nd generation or 2G ethanol process) presents a great potential for reducing both ethanol production costs and climate change impacts since agricultural residues and dedicated energy crops are used as feedstock. This study aimed at the quantification of the economic and environmental impacts considering the current an...

The nucleus of a cell has long been considered to be subject to mechanical force. Despite the observation that mechanical forces affect nuclear geometry and movement, how forces are applied onto the nucleus is not well understood. The nuclear LINC (linker of nucleoskeleton and cytoskeleton) complex has been hypothesized to be the critical structure that mediates the transfer of mechanical force...

The cell wall polysaccharides of certain oral streptococci function as receptors for the lectin-like surface adhesins on other members of the oral biofilm community. Recognition of these receptor polysaccharides (RPS) depends on the presence of a host-like motif, either GalNAcbeta1-3Gal (Gn) or Galbeta1-3GalNAc (G), within the oligosaccharide repeating units of different RPS structural types. T...

BACKGROUND Primary open angle glaucoma (POAG) is considered to be a leading cause of irreversible blindness worldwide. Matrix metalloproteinases (MMPs) and their inhibitors (TIMPs) have been extensively studied as POAG risk factors. Recently, several single-nucleotide polymorphisms (SNPs) for MMPs and TIMPs encoding genes have been reported in POAG patients. The aim of this study was to investi...

AIM Metalloproteinases (MMPs) are a family of multifunctional proteins which have been shown to be up-regulated in various types of cancer. However, the contribution of MMP1 genotype to oral cancer has not been elucidated. This study aimed to evaluate the contribution of MMP1 promoter 1607 genotype to the risk of oral cancer. MATERIALS AND METHODS In this case-control study, MMP1 genotype and...

Shiga toxin-producing Escherichia coli (STEC) are characterized by the production of Shiga toxins (Stx) encoded by temperate bacteriophages. Stx production is linked to the induction of the phage lytic cycle. Several stx variants have been described and differentially associated with the risk of developing severe illness. The variant named stx(2g) was first identified in a STEC strain isolated ...

Actualmente existe un crecimiento mundial en el consumo de energía y son los biocombustibles la alternativa viable para reducir dependencia combustibles fósiles, minimizar impacto ambiental negativo e incrementar uso fuentes alternativas. El etanol ha sido parte esta solución, su producción industrial evoluciona según tratamiento aplicado a materia prima. La segunda generación (2G) partir del m...
