Since its first recognition in the early 1960s, Derzsy's disease has caused significant economic losses in the goose meat industry through the world. Today, Derzsy's disease still maintains its importance for small-scale waterfowl farming, despite not having a significant impact on public health. In the present study, we investigated the distribution of goose parvovirus (GPV) and its potential variants from a 2019 outbreak in Turkey. Tissue samples were obtained from infected eggs and goslings that were raised in distinct farming areas of the various provinces. For this purpose, a novel primer set for amplification of a 630-bp region of VP3 was designed to confirm GPV infection by conventional PCR method. A 4709-base nucleotide sequence including the structural, non-structural, and 5' inverted terminal repeat regions was obtained from three samples from the Central Anatolian region. Multiple sequence comparisons and phylogenetic analysis demonstrated that the field strains clustered with European group 2 and contained a series of unique amino acid substitutions that might affect the virulence of the virus. These results confirmed that European-related field strains caused the outbreak in Asia Minor, and this might assist in understanding the circulation of GPV in Asia and Europe.

Conductive hydrogels have emerged as excellent candidates for the design and construction of flexible wearable sensors and have attracted great attention in the field of wearable sensors. However, there are still serious challenges to integrating high stretchability, self-healing, self-adhesion, excellent sensing properties, and good biocompatibility into hydrogel wearable devices through easy and green strategies. In this paper, multifunctional conductive hydrogels (PCGB) with good biocompatibility, high tensile (1694 % strain), self-adhesive, and self-healing properties were fabricated by incorporating boric acid (BA) and glucose (Glu) simultaneously into polyacrylic acid (PAA) and chitosan (CS) polymer networks using a simple one-pot polymerization method.

Two-dimensional transition metal dichalcogenides (2D TMDCs) have received considerable attention in local strain engineering due to their extraordinary mechanical flexibility, electonic structure, and optical properties. The strain-induced out-of-plane deformations in 2D TMDCs lead to diverse excitonic behaviors and versatile modulations in optical properties, paving the way for the development of advanced quantum technologies, flexible optoelectronic materials, and straintronic devices. Research on local strain engineering on 2D TMDCs has been delved into fabrication techniques, electronic state variations, and quantum optical applications.
