Bio-functional nanocellulose/lignocellulose-based polyurethane nanocomposite foams with enhanced flame retardancy, thermal conductivity, and thermal stability.

The necessity of developing a green, circular, and sustainable process to produce high bio-content building materials has directed current research trends. In this paper, we introduce a novel high bio-content-based polyurethane (BPU) nanocomposite foam that is prepared using 100 % bio-polyol and nanocellulose fiber (CNF). Both the bio-polyol and CNF are obtained from bamboo biomass to limit the environmental footprint of petroleum-derived materials.

Avocado seed starch utilized in eco-friendly, UV-blocking, and high-barrier polylactic acid (PLA) biocomposites for active food packaging applications.

Efficient and effective use of biopolymers, such as starch, has increasingly prompted interest due to the current environmental challenges. However, starch-based composites still show poor ductility along with water and oxygen permeability, which may not meet the requirements for food packaging standards. In this study, modified starch (m-St), isolated from the avocado seed and synthesized with tert-butyl acetoacetate (t-BAA), was embedded into polylactic acid (PLA) to design new eco-friendly composites.

Thermal degradation and flame retardancy of nylon 6/aluminum methylmethoxy phosphonate composites.

An aluminum methylmethoxyphosphonate (AlPo)-based flame retardant (FR) was synthesized. Thermal degradation and flame retardancy of nylon 6 (PA6)/AlPo composites were examined and compared with PA6/commercial aluminum diethylphosphinate (AlPi) composites. The PA6/AlPo composite achieved a V-0 rating at 20 wt% loading during the UL-94 test, and it exhibited the formation of a charred layer that protected the polymer from burning and reduced the release of gases during the combustion of PA6.

Comparative pharmacogenetic analysis of risk polymorphisms in Caucasian and Vietnamese children with acute lymphoblastic leukemia: prediction of therapeutic outcome?

Aims: Acute lymphoblastic leukemia (ALL) is the most common of all paediatric cancers. Aside from predisposing to ALL, polymorphisms could also be associated with poor outcome. Indeed, genetic variations involved in drug metabolism could, at least partially, be responsible for heterogeneous responses to standardized leukemia treatments, hence requiring more personalized therapy.

Comparison of long-term outcome between white and Vietnamese children treated for acute lymphoblastic leukemia according to the FRALLE 2000 protocol.

Aim Of This Study: To compare the relapse-free survival (RFS) in Vietnamese (n=141) and white (n=94) children living in Vietnam and Belgium, respectively, and treated in their own country for acute lymphoblastic leukemia according to the same FRALLE 2000 protocol.

Results: RFS was significantly worse in Vietnamese children (hazards ratio=4.48; 95% confidence interval [CI], 2.

Unique secondary chromosomal abnormalities are frequently found in the chronic phase of chronic myeloid leukemia in southern Vietnam.

During the Vietnam War, southern Vietnam was exposed to a large amount of dioxin, a strong human carcinogen. Although we have observed much shorter survival in southern Vietnamese chronic myeloid leukemia (CML) patients, the cause remains to be clarified. Here, we report cytogenetic and molecular findings for 47 CML patients.
