Effects of Roasting on Antibacterial and Antioxidant Properties of Buds-The Involvements of Rutin and Quercetin Constituents.

Plants (Basel)

November 2024

Laboratory of Pharmacology and Drug Development, Center of Excellent Research and Innovation, Vietnam National University of Agriculture, Gia Lam District, Hanoi 131000, Vietnam.

Roasting is the most common thermal processing method established for (SJ) buds applied as traditional medicines, and it has also been reported to alter several of their therapeutic functions. However, there have been no studies investigating the influences of roasting on the effects of these materials against bacteria. Therefore our study was performed to examine the alterations that this process would induce in SJ buds' antibacterial properties.

Gravity may exert species-specific effects on quadrupedal vasoreactivity, reflecting variations in the vertical displacement of the cardiocranial axis from the dorsal plane. Deer show markedly displaced cardiocranial axes compared to their closest phylogenetic relatives, but their relative cerebrovascular responses remain unelucidated. Accordingly, we investigated the responses to noradrenaline (NA), acetylcholine (ACh), 5-hydroxytryptamine (5-HT), histamine, angiotensin (Ang) II, and bradykinin (BK) in cervine basilar arterial rings.

Article Synopsis
  • * A study tested the oral toxicity of five common insecticides on four honey bee species, finding that the managed Asian honey bee (Apis cerana) showed the highest tolerance to these chemicals.
  • * The wild species, particularly the giant (A. dorsata) and red dwarf honey bee (A. florea), were more sensitive to the pesticides, emphasizing the need for better pesticide risk assessments and regulations to protect various honey bee species.

African swine fever (ASF) is an economically devastating viral disease of pigs caused by the ASF virus (ASFV). The rapid global spread of ASF has increased the demand for ASF diagnostics to be readily available and accessible. No commercial ASF enzyme-linked immunosorbent assay (ELISA) kits are manufactured and licensed in North America.

  • This study explored genomic selection (GS) and genome-wide association studies (GWAS) in Vietnamese dairy cattle for various traits related to milk production and health, despite limited individual phenotype data from smallholder farms.
  • Researchers collected phenotype data from 345 lactating cows across 32 smallholder dairy farms in different regions of Vietnam, alongside genetic samples for analysis.
  • The heritability estimates ranged from moderate to very low for different traits, indicating variability in genetic potential, with low accuracy for genomic estimated breeding values (GEBVs) suggesting challenges in breeding predictions.

: African swine fever virus (ASFV) continues to spread globally, causing severe economic losses to pig farmers. Vietnam licensed two live attenuated vaccines based on the ASFV strains ASFV-G-ΔI177L and ASFV-G-ΔMGF to control the ongoing ASF outbreaks. In 2023, newly emerging highly virulent recombinant ASF viruses (rASFV I/II) containing genetic elements from both p72 genotype I and II ASF viruses were reported from Northern Vietnam.

The predation capacity and functional responses of adult females of the phytoseiid mites (Muma), (Corpuz and Rimando), (Corpuz and Rimando), and (Athias-Henriot) were studied on eggs and first instars of the western flower thrips, (Pergande), in the laboratory at 25 °C and 30 °C. At both temperatures, the functional response of all four phytoseiid mites was type II to first instars of the thrips. In contrast, when offered thrips eggs, the functional response was type III.

Genotype × environment (GxE) interaction effects are one of the major challenges in identifying cultivars with stable performance across agri-environments. In this study we analysed GE interactions to identify quinoa (Chenopodium quinoa) cultivars with high and stable yields under different soil moisture regimes, representing control conditions, waterlogging and drought. Waterlogging and drought treatments were artificially induced using normoxia, a combination of hypoxia-normoxia, and 10% PEG (Polyethylene glycol) under hydroponic growth conditions, respectively.

Male infertility is a multifactorial disease due to spermatogenesis impairment, with etiology remaining unknown for roughly one-third of infertile cases. Several studies have demonstrated that genetic variants are male infertility risk factors. CFAP43 and TEX14 are involved in the spermatogenesis process.

Article Synopsis
  • This study investigates the effects of second litter syndrome (SLS) on the reproductive performance of sows, especially focusing on metrics like piglets born alive (PBA) and farrowing intervals (FI) across up to five reproductive cycles.
  • About 47.8% of sows experienced SLS, which significantly decreased their accumulative number of piglets born alive for the first two parities but showed comparable performance in later parities compared to sows without SLS.
  • The study concludes that SLS does not significantly harm future reproductive performance, suggesting that sows affected by SLS may not need to be culled, and calls for further research on the underlying mechanisms of PBA fluctuations.

African swine fever (ASF) is one of the deadliest swine diseases, causing significant economic losses, threatening food security, and limiting pig production in affected countries. In the absence of an effective ASF vaccine, prevention and control of ASF depend mainly on effective biosecurity measures. In this study, the efficacy of SAFER, a powdered disinfectant containing clay, an acid complex, and the active ingredient thyme essential oil, was tested against the ASF virus.

Quantifying carbon footprint of salmon fillet processed in Vietnam: impact of transportation and improvement opportunities.

Environ Sci Pollut Res Int

September 2024

Department of Environmental Management, School of Environmental Science and Technology, Hanoi University of Science and Technology, Hanoi, Vietnam.

The carbon footprint of a product represents the amount of greenhouse gas (GHG) emissions released during its production, transportation, and consumption and is calculated as carbon dioxide equivalent (CO). It should be integrated into different existing and future seafood awareness campaigns to create more holistic yardsticks by which consumers, retail businesses, and producers can assess the environmental impacts of seafood. This study used the life cycle assessment (LCA) method for the first time to quantify the carbon footprint of salmon fillet products processed in Vietnam for export.

A Non-Hemadsorbing Live-Attenuated Virus Vaccine Candidate Protects Pigs against the Contemporary Pandemic Genotype II African Swine Fever Virus.

Viruses

August 2024

Center on Biologics Development and Evaluation, Department of Anatomy and Physiology, College of Veterinary Medicine, Kansas State University, Manhattan, KS 66506, USA.

African swine fever (ASF) is a highly contagious and severe hemorrhagic transboundary swine viral disease with up to a 100% mortality rate, which leads to a tremendous socio-economic loss worldwide. The lack of safe and efficacious ASF vaccines is the greatest challenge in the prevention and control of ASF. In this study, we generated a safe and effective live-attenuated virus (LAV) vaccine candidate VNUA-ASFV-LAVL3 by serially passaging a virulent genotype II strain (VNUA-ASFV-L2) in an immortalized porcine alveolar macrophage cell line (3D4/21, 50 passages).

Currently, numerous glycosides have been synthesized and used in clinical applications, neutraceuticals, cosmetics, and food processing. Structurally, a glycoside is composed of aglycone attaching to one or several sugar moieties so-called glycone. It is found that biochemical or biopharmaceutical properties of glycoside are mainly determined by its sugar part and thereby alternation of this glycone resulting in novel structure and characteristics as well.
