Novel genotyping assay for a 212-kb deletion from the gene, and frequency of the allele in pig populations in Vietnam.

Piglet lethality is one of the major concerns in pig breeding programs. Deletion of a 212-kb region within the Bardet-Biedl syndrome 9 () gene has been linked to a reduction in the number of piglets born alive per litter. The mutant gene carrier-by-carrier mating scheme could result in mummification of piglets carrying 2 copies of the mutant allele, which ultimately affects the reproductive performance of the sow.

Roles of β-Indole Acetic Acid (IAA) Producing Endophytic Bacteria on the Recovery of Plant Growth and Survival Ability of Sugarcane Infected White Leaf Disease (SWLD).

β-Indole acetic acid is produced in the rhizosphere by endophytic bacteria and promotes plant growth. Effects of bacterial IAA producers (BIPs) on plant growth and recovery of sugarcane seedlings infected with phytoplasma causing white leaf disease (SWLD) were examined. Fifty-five endophytic bacteria isolated from rice roots were collected from the Mekong River Delta, Vietnam.

An Assessment of Outpatient Satisfaction with Hospital Pharmacy Quality and Influential Factors in the Context of the COVID-19 Pandemic.

The study aims to evaluate outpatient satisfaction (OS) with health insurance drug dispensing at the central hospital in Vietnam and to explore the influential factors. A cross-sectional survey was conducted on adult outpatients via an adjusted SERVQUAL questionnaire. The questionnaire's internal consistency (Cronbach alpha) and construct validity (exploratory factor analysis) were considered.

Identification of potential microRNA groups for the diagnosis of hepatocellular carcinoma (HCC) using microarray datasets and bioinformatics tools.

Hepatocellular carcinoma (HCC) is the most common primary liver malignancy and the third cause of cancer-related death worldwide. Potential microRNAs have been reported as biomarkers for early detection of HCC as well as novel molecular targets for HCC treatment. Various tissue expression profiles of miRNAs using three microarray datasets from groups in Asia (2), Europe, America (GSE147892, GSE21362, GSE74618, GSE40744) and multiple bioinformatics tools were integrated to determine the most significant miRNA groups to assist in the diagnosis of HCC.

Unraveling the Host-Selective Toxic Interaction of Cassiicolin with Lipid Membranes and Its Cytotoxicity.

Cassiicolin (Cas), a toxin produced by , is responsible for Corynespora leaf fall disease in susceptible rubber trees. Currently, the molecular mechanisms of the cytotoxicity of Cas and its host selectivity have not been fully elucidated. Here, we analyzed the binding of Cas1 and Cas2 to membranes consisting of different plant lipids and their membrane disruption activities.

Cervical intra-extradural meningioma with en-plaque, dumbbell-shaped, and an unusual calcified pattern in a young patient.

Background: Most spinal meningiomas primarily grow in the intradural extramedullary location. Epidural meningiomas are uncommon; if detected, they usually coexist with intradural lesions. They inhere more aggressive and invasive characteristics compared with their counterparts inside the dura.

Loop-mediated isothermal amplification (LAMP) assay for detection of sesame phyllody phytoplasmas in Vietnam.

Phloem-limiting phytoplasmas are known to be causal agents of phyllody, which is recognized by the abnormal development of floral structures resulting in serious yield losses in sesame plants. Currently, identification of the various groups of phytoplasmas that cause sesame phyllody (SP) is conducted by nested PCR, RFLP, and multiplex real-time qPCR assays. However, these methods require intensive labor and are costly and time-consuming so can only be undertaken in well-equipped labs.

Development of a SCAR marker linked to fungal pathogenicity of rice blast fungus Magnaporthe Oryzae.

PCR-based molecular approaches including RAPD (random amplified polymorphic DNA), ISSR (inter-simple sequence repeat), and SRAP (sequence-related amplified polymorphism) are commonly used to analyze genetic diversity. The aims of this study are to analyze genetic diversity of M. oryzae isolates using PCR-based molecular approaches such as RAPD, ISSR, and SRAP and to develop SCAR marker linked to the pathogenicity of rice blast fungus.

Effects of floral resources on the longevity and parasitism of Haliday (Hymenoptera: Braconidae) on (L.) (Lepidoptera: Plutellidae) in Vietnam.

Parasitoids are important biological control of crop pests. In Vietnam, is a native wasp species that has demonstrated its applicability as a natural insect pest enemy. Many adult parasitoids require food resources such as nectar and pollen to optimize their life cycles.

A molecular study of (Hemiptera, Aphididae) in Costa Rica.

The genus (Takahashi) (Aphididae: Neophyllaphidinae) is composed of 18 species; however, in the Americas only nine species have been reported previously. A new species, Miller & Halbert, was described in 2014 in USA. Colonies resembling those of this new species have been observed in Costa Rica on spp.

Expression of Plasma hsa-miR122 in HBV-Related Hepatocellular Carcinoma (HCC) in Vietnamese Patients.

Background: Hepatocellular carcinoma (HCC) is the leading cause of cancer-related death in the world and considered as one of the most susceptible cancers in humans. The microRNA molecule, hsa-miR122, considered as a potential biological marker linked with the injury of hepatocellular tissue, is the most common microRNA in human liver cancer. Understanding the expression profile of hsa-miR122 plays an important role in the diagnosis of HCC.

Closed tube loop-mediated isothermal amplification assay for rapid detection of hepatitis B virus in human blood.

Recently, many studies have demonstrated the significant advantages of loop-mediated isothermal amplification (LAMP) based methods over serological tests and PCR for rapid detection of microbial pathogens. Here, a rapid LAMP assay was developed to detect the hepatitis B virus (HBV) from DNA, and particularly, blood samples from infected patients using a commercially available master mix and portable real-time fluorometer. The final optimized fluorescence-based LAMP assay provided significant amplification time of less than 15 minutes compared with over 1 hour for PCR and an opened tube LAMP system described previously.

The Role of Cell Wall Degrading Enzymes in Pathogenesis of Magnaporthe oryzae.

The plant cell wall is always the physical barrier in which phytopathogenic fungi must overcome by producing an array of cell wall degrading enzymes (CWDEs) that allow them to invade host tissues through the degradation of cell wall components of plants. Magnaporthe oryzae is a causal agent of blast disease, one of the most devastating disease in rice resulting significant crop losses worldwide. The penetration of plant cuticle and cell walls induced by infection structures of M.

The impact of different multi-walled carbon nanotubes on the X-band microwave absorption of their epoxy nanocomposites.

Background: Carbon nanotube (CNT) characteristics, besides the processing conditions, can change significantly the microwave absorption behavior of CNT/polymer composites. In this study, we investigated the influence of three commercial multi-walled CNT materials with various diameters and length-to-diameter aspect ratios on the X-band microwave absorption of epoxy nanocomposites with CNT contents from 0.125 to 2 wt%, prepared by two dispersion methods, i.

Transcriptional control and protein specialization have roles in the functional diversification of two dicer-like proteins in Magnaporthe oryzae.

Quantitative RT-PCR and overexpression studies of two Dicer-like proteins, MoDcl1 and MoDcl2, in Magnaporthe oryzae indicated that the functional diversification of the MoDcl1 and MoDcl2 proteins in RNA-mediated gene silencing pathways was likely to have arisen from both transcriptional control and protein specialization.

RNA silencing as a tool for exploring gene function in ascomycete fungi.

We have developed a pHANNIBAL-like silencing vector, pSilent-1, for ascomycete fungi, which carries a hygromycin resistance cassette and a transcriptional unit for hairpin RNA expression with a spacer of a cutinase gene intron from the rice blast fungus Magnaporthe oryzae. In M. oryzae, a silencing vector with the cutinase intron spacer (147 bp) showed a higher efficiency in silencing of the eGFP gene than did those with a spacer of a GUS gene fragment or a longer intron (850 bp) of a chitin binding protein gene.
