Biological bone screws play an important role chateau sissan 2019 in fixing fractures and bone defects.The machining of helical grooves on xenogenic materials is a key part of fabricating biological bone screws.The fabrication of helical grooves on bovine bone using micro-abrasive air jets was investigated in this paper.The helical groove shapes we
The metal structures distributed in underground coal mine roadways can be equivalent to the receiving antenna to absorb electromagnetic wave energy and release the energy in the form of discharge sparks under specific conditions.The accumulated energy has the risk of igniting explosive gas.In order to solve the problem, the conditions of ignition o
Temporin-GHa (GHa) was cloned from Hylarana guentheri, showing a weak antimicrobial activity.In order to improve its bactericidal efficacy, GHaR6R, GHaR7R, GHaR8R and GHaR9W were designed and synthesized.Compared to the parent peptide, the GHa-derived peptides show potent antimicrobial activities against methicillin-resistant Staphylococcus aureus
The ability to quantify changes in the structural complexity of reefs and individual coral colonies that build them is vital to understanding, managing, and restoring the function of these ecosystems.However, traditional methods for quantifying coral growth in situ fail to accurately quantify the diversity of morphologies observed both among and wi
ABSTRACT Extracellular vesicles (EVs) produced by members of the Cryptococcus genus are associated with fundamental processes of fungal physiology and virulence.However, several questions about the properties of cryptococcal EVs remain unanswered, mostly because of technical limitations.We recently described a fast and efficient protocol of high-yi
