UbiB proteins mediate an ATP‐dependent decarboxylation step in bacterial ubiquinone biosynthesis

The FEBS Journal, EarlyView.
UbiB proteins are atypical protein kinase‐like enzymes essential for ubiquinone biosynthesis. Here, we demonstrate that bacterial UbiB proteins catalyze the O2‐dependent decarboxylation of ubiquinone precursors, a process linked to their ATPase activity.

Fracture Mechanics-Based Modelling of Tool Wear in Machining Ti6Al4V Considering the Microstructure of Cemented Carbide Tools

Journal of Machine Engineering
This study introduces a new wear model that can predict tool life in the milling process of Ti6Al4V using a cemented carbide tool. The model uses a finite element (FE) simulation to predict crack growth in the tool material microstructure.

Tool-wear analysis in cryogenic machining of NiTi shape memory alloys: A comparison of tool-wear performance with dry and MQL machining

, 2013
Extremely high tool-wear rate in machining of NiTi shape memory alloys (SMAs) is one of the major reasons for limiting the use of conventional machining processes on NiTi.

TcFur1, a furin 1 ortholog in Tribolium castaneum, regulates reproduction and carbohydrate metabolism without affecting lipid homeostasis

Insect Molecular Biology, EarlyView.
TcFur1, a furin 1 ortholog in Tribolium castaneum, is highly expressed in pupae and declines in adults. TcFur1 knockdown reduces oviposition but does not alter triacylglycerol levels or total lipase activity. TcFur1 knockdown increases circulating trehalose and decreases expression of insulin‐like peptides and the AKH receptor.

A deeper look into the diversity of suckermouth catfishes (Mochockidae: Chiloglanis Peters 1868) of southern Africa, with the description of four new species

Journal of Fish Biology, EarlyView.
Abstract Suckermouth catfishes of the genus Chiloglanis Peters 1868 are small and predominantly rheophilic fishes endemic to Africa. This genus is quite diverse, with over 70 species distributed across most river systems on the continent, except for the Cape Fold ecoregion and most of northern Africa.

Effects of Cutting Insert Flank Wear in Previous Turning and Subsequent Diamond Burnishing on the Surface Integrity, Microstructure and Fatigue Limit of Heat-Treated C45 Steel

Metals
Burnishing technologies are a cheap and effective means of improving the surface integrity (SI) and performance of metal components. However, there is practically no information about the integral influence of the preceding turning process on the initial

Rapid RPA‐Cas12a Assay for Streptococcus agalactiae Serotype III in Fish Featuring Photocontrolled One‐Pot Detection

Journal of Fish Diseases, EarlyView.
ABSTRACT Streptococcus agalactiae is a primary pathogen responsible for significant mortality in tilapia, a critical and affordable source of animal protein. Among the various serotypes affecting aquaculture, serotype III is increasingly recognized for its high virulence and zoonotic potential, with multidrug resistance reported in some lineages ...

Feasibility of Functional Near‐Infrared Spectroscopy in Assessing Prefrontal Cortical Activation During Behaviour Inhibition in Williams Syndrome

Journal of Intellectual Disability Research, EarlyView.
ABSTRACT Background Williams syndrome (WS) is a genetic condition associated with neurodevelopmental disorders including intellectual disability and executive functioning (EF) deficits. Although neuroimaging methods may clarify the neural basis of these impairments, participant burden and frequent exclusion of individuals with lower cognitive abilities

Palaces for a New Spain Nobility: Between Creole Identity and Academicism

Sociology Lens, Volume 38, Issue 1, Page 75-86, March 2025.
ABSTRACT Mexico City and Havana had a significant number of noble palaces during the eighteenth century. Until now, the dearth of historical documentation on their construction has hampered any approximation, requiring other methodologies. Here, it is intended to establish how a new visual code was defined, consistent both with their local style and ...

Comparative genomics of dark septate endophytes: shedding light on the enigmatic lifestyle and biology of DSEs

New Phytologist, EarlyView.
Ancestral lifestyle reconstruction across the phylogeny of the 107 analysed fungal genomes. Summary Dark septate endophytes (DSE) are widespread root‐colonising fungi with poorly understood lifestyle and ecological functions. We investigated their genomic traits, sexual reproduction signatures, carbohydrate‐active enzyme (CAZyme) and secondary ...
