A new integrated circular economy index and a combined method for optimization of wood production chain considering carbon neutrality.

The wood industry is potentially advantageous to applying the concepts of circular economy for sustainable development and can contribute to the commitment of carbon neutrality. This study developed an integrated circular economy index based on five different quantitative indicators for assessment of the wood production chain: heat recovery rate, CO sequestration rate, fossil fuel substitution rate, renewable electricity usage rate, and revenue increase from the by-products. A combination of best-worst method (BWM) and linear goal programming (LGP) techniques was investigated to develop an optimal circular economy model of wood processing chain for reduction in CO emission.

Wild geckos considered as the natural reservoir of Salmonella Weltevreden in Southeast Asian countries.

A total of 1,318 wild geckos were collected in Cambodia, Thailand and Vietnam (Hue and the Mekong Delta) from 2012 to 2015 to determine the prevalence of Salmonella Weltevreden. Those geckos belong to three species: common house gecko (Hemidactylus frenatus), flat-tailed house gecko (Hemidactylus platyurus) and four-clawed gecko (Gehyra mutilata). Of 1,318 gecko samples, 293 (22.

Polarization dependence of Cs 6S-6P-11S electromagnetically induced transparency at room temperature.

The effect of polarization on the ladder-type electromagnetically induced transparency (EIT) spectra of Cs atoms at room temperature for the transitions 6P-6P-11S is experimentally studied. The entire spectra with additional peaks arising from the Doppler effect are observed. As the relative angle between the probe's and coupling's plane of polarization arranges at 0, 45, and 90, the peak height ratio of 44'3" to 44'4" increases by more than 7 times with corresponding values of 0.

Novel compound heterozygous TMEM67 variants in a Vietnamese family with Joubert syndrome: a case report.

Background: Joubert syndrome is a genetically heterogeneous autosomal recessive ciliopathy characterized by the combination of hypoplasia/aplasia of the cerebellar vermis, thickened and elongated superior cerebellar peduncles and a deep interpeduncular fossa, known as "molar tooth sign" associated with hypotonia, respiratory control disturbances and abnormal eye movements. To date, pathogenic variants in over 35 genes are known to cause autosomal recessive Joubert Syndrome, while one gene is associated with X-linked recessive inheritance.

Case Presentation: We describe here a non-consanguineous Vietnamese family with Joubert syndrome, a fetus and 10-year-old developmentally delayed boy.

The importance of wild gecko as a source of human Salmonella infection.

A total of 201 wild geckos from the region of Mekong Delta, Vietnam were collected to determine the viable number and survival period of Salmonella in their feces. Of the 101 samples examined, 24 (23.8%) were Salmonella positive.

Characterization of Microvesicles Released from Human Red Blood Cells.

Background/aims: Extracellular vesicles (EVs) are spherical fragments of cell membrane released from various cell types under physiological as well as pathological conditions. Based on their size and origin, EVs are classified as exosome, microvesicles (MVs) and apoptotic bodies. Recently, the release of MVs from human red blood cells (RBCs) under different conditions has been reported.

Differential but direct abolishment of human regulatory T cell suppressive capacity by various TLR2 ligands.

CD4(+)CD25(high) regulatory T cells (Tregs) control cellular immune responses and maintain peripheral tolerance. We investigated whether TLR2 ligands are able to abrogate Treg-induced suppression in humans based on different reports about effects of triacylated lipopeptide Pam(3)CSK4 in mice. Pretreatment of human Tregs with a mixture of TLR2 ligands Pam(2)CSK4, FSL-1, and Pam(3)CSK4 reduced the Treg-mediated suppression of CD4(+)CD25(-) responder T cells in the majority of the analyzed donors.

Activation of the Ran GTPase is subject to growth factor regulation and can give rise to cellular transformation.

Although the small GTPase Ran is best known for its roles in nucleocytoplasmic transport, mitotic spindle assembly, and nuclear envelope formation, recent studies have demonstrated the overexpression of Ran in multiple tumor types and that its expression is correlated with a poor patient prognosis, providing evidence for the importance of this GTPase in cell growth regulation. Here we show that Ran is subject to growth factor regulation by demonstrating that it is activated in a serum-dependent manner in human breast cancer cells and, in particular, in response to heregulin, a growth factor that activates the Neu/ErbB2 tyrosine kinase. The heregulin-dependent activation of Ran requires mTOR (mammalian target of rapamycin) and stimulates the capped RNA binding capability of the cap-binding complex in the nucleus, thus influencing gene expression at the level of mRNA processing.

Antimicrobial susceptibilities of Salmonella from domestic animals, food and human in the Mekong Delta, Vietnam.

A total of 230 Salmonella isolates representing 33 serotypes originated from food (pork, beef, chicken meat, duck meat, and shrimp), domestic animals (pig, chicken, and duck), and human (children with diarrhea) in the Mekong Delta, Vietnam were examined for the antimicrobial resistance to 10 antibiotics. Of the 230 Salmonella isolates examined, 49 (21.3%) showed antimicrobial resistance.

In migrating cells, the Golgi complex and the position of the centrosome depend on geometrical constraints of the substratum.

Although cells migrate in a constrained 3D environment in vivo, in-vitro studies have mainly focused on the analysis of cells moving on 2D substrates. Under such conditions, the Golgi complex is always located towards the leading edge of the cell, suggesting that it is involved in the directional movement. However, several lines of evidence indicate that this location can vary depending on the cell type, the environment or the developmental processes.

Two isoforms of tissue transglutaminase mediate opposing cellular fates.

Opposing cellular responses are typically regulated by distinct sets of genes. However, tissue transglutaminase (TGase) provides an interesting example of a single gene product that has been implicated both in affording protection against cellular insults as well as in promoting cell death. Here, we shed some light on how these conflicting activities might be manifested by demonstrating that alternative transcripts of TGase differentially affect cell viability.

Cool-1 functions as an essential regulatory node for EGF receptor- and Src-mediated cell growth.

Cool-1 (cloned-out of library 1) has a key role in regulating epidermal growth factor receptor (EGFR) degradation. Here, we show that Cool-1 performs this function by functioning as both an upstream activator and downstream target for Cdc42. EGF-dependent phosphorylation of Cool-1 enables it to act as a nucleotide exchange factor for Cdc42 and to form a complex with the E3 ligase Cbl, thus regulating Cbl-catalysed EGFR degradation.

Human Lsg1 defines a family of essential GTPases that correlates with the evolution of compartmentalization.

Background: Compartmentalization is a key feature of eukaryotic cells, but its evolution remains poorly understood. GTPases are the oldest enzymes that use nucleotides as substrates and they participate in a wide range of cellular processes. Therefore, they are ideal tools for comparative genomic studies aimed at understanding how aspects of biological complexity such as cellular compartmentalization evolved.

Prevalence of Salmonella spp. in pigs, chickens and ducks in the Mekong Delta, Vietnam.

In order to determine the prevalence of Salmonella spp. in domestic animals in 6 provinces of the Mekong Delta, Vietnam, 1,098 fecal or intestinal content samples from pigs, chickens, and ducks were examined in the period from July to October, 2000. Salmonella spp.

Structural basis of m7GpppG binding to the nuclear cap-binding protein complex.

The 7-methyl guanosine cap structure of RNA is essential for key aspects of RNA processing, including pre-mRNA splicing, 3' end formation, U snRNA transport, nonsense-mediated decay and translation. Two cap-binding proteins mediate these effects: cytosolic eIF-4E and nuclear cap-binding protein complex (CBC). The latter consists of a CBP20 subunit, which binds the cap, and a CBP80 subunit, which ensures high-affinity cap binding.
