Article Abstract
Understanding molecular epidemiology is essential for the improvement of lumpy skin disease (LSD) eradication and control strategies. The objective of this study was to perform a molecular characterization and phylogenetic analysis of lumpy skin disease virus (LSDV) isolated from dairy cows presenting LSD-like clinical signs in northern Thailand. The skin nodules were collected from 26 LSD-suspected cows involved in six outbreaks during the period from July to September of 2021. LSDVs were confirmed from clinical samples using the polymerase chain reaction (PCR). The PCR-positive samples were subsequently amplified and sequenced using a G-protein-coupled chemokine receptor (GPCR) gene for molecular characterization and phylogenetic analyses. All 26 samples were positive for LSDV by PCR. A phylogenetic analysis indicated that the 24 LSDV isolates obtained from cattle in northern Thailand were closely related to other LSDV sequences acquired from Asia (China, Hong Kong, and Vietnam). On the other hand, two LSDV isolates of the cows presenting LSD-like clinical signs after vaccination were clustered along with LSDV Neethling-derived vaccines. The outcomes of this research will be beneficial in developing effective control strategies for LSDV.

The movement of molecules across the membranous barriers of a cell is fundamental to cellular homeostasis in every living organism. This vital process is facilitated through a mechanistically diverse class of proteins, collectively known as membrane transporters. Among these are so-called carrier proteins that can function in passive and active transport mechanisms.

The ability of parasitoid wasps to precisely locate hosts in complex environments is a key factor in suppressing pest populations. Chemical communication plays an essential role in mediating insect behaviors such as locating food sources, hosts, and mates. Odorant receptors (ORs) are the key connection between external odors and olfactory nerves.

During brewing processes, proteins such as lipid transfer protein 1 (LTP1) are exposed to high temperatures, which later affects the beer foam properties. To develop high-quality beer, it is therefore essential to understand the protein chemical modifications and structural alternations induced by the high temperatures and their impact on beer foam. This study characterizes heat-induced chemical modifications and changes in the molecular size distribution and structure of LTP1 and its lipid-bound isoform, LTP1b, using size-exclusion chromatography and reverse-phase chromatography/mass spectrometry.

This study demonstrates the successful fabrication of nanostructured Langmuir-Blodgett (LB) films combining the conjugated copolymer poly(9,9-dioctylfluorene--3,4-ethylenedioxythiophene) (PDOF--PEDOT) with spherical and triangular silver nanoparticles (AgNP). The LB technique allowed precise control over the molecular arrangement and distribution of the nanoparticles at the air-water interface, resulting in compact, reproducible and structurally ordered nanocomposite films. The structural and morphological properties of the interfacial monolayers and LB films were investigated using surface pressure-area isotherms, Brewster angle microscopy, polarization modulation infrared reflection-absorption spectroscopy (PM-IRRAS) and quartz crystal microbalance.

The cytosolic iron-sulfur cluster assembly (CIA) targeting complex maturates over 30 cytosolic and nuclear Fe-S proteins, raising the question of how a single complex recognizes such a diverse set of clients. The discovery of a C-terminal targeting complex recognition (TCR) peptide in up to 25% of CIA clients provided a clue to substrate specificity, yet the molecular and energetic basis for this interaction remained unresolved. By integrating computational and biochemical approaches, we show that the TCR peptide binds a conserved interface between the Cia1 and Cia2 subunits of the targeting complex, even in the absence of the Fe-S cluster.
