ZV

Zero-valent silver nanoparticles (ZV-AgNPs) are known as potential antimicrobials and here we report antifungal activity of ZV-AgNPs against Colletotrichum falcatum Went for the first time. ZV-AgNPs were synthesized by using a native Bacillus sp. strain AW1-2, which was identified through 16S rRNA gene sequence analysis. Biogenic ZV-AgNPs were confirmed by monitoring a characteristic absorption peak of UV-vis spectroscopy that was measured at 447 nm. Further, it was found through FTIR and XRD analysis that ZV-Ag nanocrystals were capped with proteins of bacterial origin and their size ranged from 22...

Aquaculture's sustainability deeply relies on the identification and inclusion of alternative raw materials. Although meals from insects and/or byproducts from different industries are being recently tested, the meal from terrestrial vegetable species is still the main substitution candidate for fish meal. Here the effects of 0% (Control), 10% (A10) and 30% (A30) inclusion of Narbonne vetch ( Vicia narbonensis ; ZV-156 strain) meal in rainbow trout ( Oncorhynchus mykiss ) diets was assessed in a 63-day feeding trial by means of growth performance, histopathological, nutritional value of the fish fillet and blood biochemistry analyses...

Virus-induced infection such as SARS-CoV-2 is a serious threat to human health and the economic setback of the world. Continued advances in the development of technologies are required before the viruses undergo mutation. The low concentration of viruses in environmental samples makes the detection extremely challenging; simple, accurate and rapid detection methods are in urgent need. Of all the analytical techniques, electrochemical methods have the established capabilities to address the issues. Particularly, the integration of nanotechnology would allow miniature devices to be made available at the point-of-care...

We report studies of the complex magnetic ordering, pressure-induced magnetic properties, large exchange bias (EB), spin-glass (SG), critical behavior, and electron spin resonance (ESR) in spinel Co2TiO4. The magnetic compensation behavior occurs in the vicinity of the compensation temperature Tcomp ∼ 32.5 K (defined as the susceptibility χZFC = χFC = 0), which can be attributed to the behavior that the magnetization of two bulk sublattices balances each other completely. The nature of this unusual case is demonstrated by the spin direction upon applied field and A-B sublattice (site) coupling...

BACKGROUND AND AIMS: In addition to preventing water loss, plant cuticles must also regulate nutrient loss, leaching. The eceriferum mutants in Hordeum vulgare (barley) potentially influence these functions by altering epicuticular wax structure and composition. METHODS: Cultivar Bonus and five of its cer mutants were grown under optimal conditions for vegetative growth and maturation, and nine traits were measured. Nutrient and water amounts going through the soil plus the amount of simulated rain as deionized water, affecting phyllosphere humidity, delivered during either the vegetative or maturation phase were varied...

BACKGROUND: The emergence of Zika virus (ZV) in tropical and subtropical areas of the world has created an urgent need for vaccines against ZV. However, approved vaccines that prevent ZV infection are not available. To develop an effective vaccine against ZV infection, a lipidated form of ZV envelope protein domain III that possesses an intrinsic adjuvant property was rationally designed. Our goal was to examine the immunogenicity of recombinant lipidated ZV envelope protein domain III (rLZE3) and evaluate its potential as a vaccine candidate against ZV...

Lignocellulosic biomass waste is a cheap, eco-friendly, and sustainable raw material for a wide array of applications. In the present study, an easy, fast, and economically feasible route has been proposed for the preparation of different zero-valent metal nanoparticles (ZV-MNPs) based on Cu, Co, Ag, and Ni NPs using empty fruit bunch (EFB) biomass residue as support material. The catalytic efficiency of ZV-MNPs/EFB catalyst was investigated against five model pollutants, such as methyl orange (MO), congo red (CR), methylene blue (MB), acridine orange (AO), and 4-nitrophenol (4-NP) using NaBH4 as a source of hydrogen and electron...

A novel Gram-stain-negative bacterial strain designated as MEB193T was isolated from a sediment sample collected from Lonar Lake, India. The cells were motile, non-spore-forming and rod-shaped. The strain was oxidase- and catalase-positive. It grew optimally at pH 9.0 and at 1 % (w/v) NaCl concentration at 30 °C. Based on 16S rRNA gene sequence similarity, MEB193T belongs to genus Nitrincola , with Nitrincola alkalilacustris ZV-19T (95.89 %) and Nitrincola lacisaponensis 4CAT (95.87 %) as its closest neighbours...

We have investigated the structural and magnetic properties of a new cubic spinel LiZn2 V3 O8 (LZVO) through x-ray diffraction, dc and ac susceptibility, magnetic relaxation, aging, memory effect, heat capacity and7 Li nuclear magnetic resonance (NMR) measurements. A Curie-Weiss fit of the dc susceptibility χ dc ( T ) yields a Curie-Weiss temperature θCW = -185 K. This suggests strong antiferromagnetic (AFM) interactions among the magnetic vanadium ions. The dc and ac susceptibility data indicate the spin-glass behavior below a freezing temperature T f ≃ 3 K...

OBJECTIVES: Immunocompromised subjects are at increased risk for herpes zoster (HZ) and HZ-related complications, such as post herpetic neuralgia (PHN). We describe health utilities, health care resource utilization (HCRU), productivity loss and health care costs in recipients of autologous hematopoietic stem cell transplantation (Auto-HSCT) who developed confirmed HZ in the phase 3 clinical trial. METHODS: HCRU, costs, and EQ-5D-3L utility were assessed for 155 confirmed HZ cases observed after receiving inactivated varicella zoster virus (VZV) vaccine (ZVIN ) or placebo...

The aim of the present study was to determine the effects of selective dry cow treatment (SDCT) on udder health in Swiss dairy farms compared to a blanket dry cow treatment (BDCT). Cows with a somatic cell count (SCC) of less than 250'000 cells/ml and after BDCT in the previous dry period were selected. These animals received a SDCT in the subsequent dry period. Cows with less than 150,000 cells/ml or a negative California mastitis test (CMT) received either no treatment (group oB) or an internal teat sealant (group ZV) in all teats...

Background and aims: Enteral administration of glutamine has been proposed as an effective recovery of intestinal barrier function. This amino acid has a modulating effect on the reducing bacterial translocation, which can influence immune functions of the intestine. The objective was to evaluate the effects of early enteral glutamine supplementation on intestinal permeability in critically ill patients. Materials and methods: A total of 80 critically ill patients older than 18 years were randomly assigned to one of two groups according to the stratified blocked randomization by age and admission category...

The auditory system has an extensive efferent innervation, which contributes to processes of control and regulation of the afferent input. The expression of receptors to various neurotransmitters and neuropeptides in the inner ear has been described, among which endogenous opioid receptors are found. The role of opioid receptors in the cochlea is not yet fully defined, it has been reported that opioid agonists and antagonists modulate the response to auditory stimuli and in clinical practice, multiple cases have been reported in which the consumption of opioid derivatives induce sensorineural hearing loss...

Herpes zoster is a viral infectious disease caused by reactivation of varicella zoster virus (VZV) in a latently infected ganglion, and is characterized by blistering and pain developing in a zonal region innervated from the ganglion. Amenamevir is an antiherpes agent that does not have a nucleic acid-like structure, and exerts antiviral action by inhibiting the enzymatic activity of a virus-derived helicase-primase complex, which is considered essential for viral DNA replication. Amenamevir is mainly metabolized by CYP3A, and excreted into feces...
