The chemical reactions occurring in the thermal treatment of bisphenol-A polycarbonate (PC) and poly(methyl methacrylate) (PMMA) blends have been investigated by nuclear magnetic resonance (NMR), mass spectrometry (MS), size exclusion chromatography (SEC), and thermogravimetry (TG). Our results...
All cells with ___ receptors exhibit a variable response to ACh. The chemical operations occurring within the body that are necessary for conversion of nutrients are known collectively as: A. homeostasis. B. metabolism. C. syndrome. D. pathology. Fill in the blank: The process of mei...
Tuberculosis is the leading cause of death from a single infectious agent, with over 25% of these occurring in the African region. Multi-drug resistant strains which do not respond to first-line antibiotics continue to emerge, putting at risk numerous public health strategies which aim to reduce...
Intracellular transport of molecules is crucial for the normal function and growth of living cells1. Many intracellular signaling cascades, such as those mediated by calcium ions (), are generated by biochemical reactions and diffusion, which are often hard to accurately measure on the submillisecond...
A further study investigated the chemical changes occurring within the pores of β-TCP granules incubated in a simulated body fluid. The results detected definitive pH, calcium and phosphate changes inside the bone substitute granules that lasted for several days [21]. Simi- lar changes may have ...
Although diverse tailoring enzymes are found to be clustered with cyclodipeptide synthases (CDPSs) to perform further modification reactions on the diketopiperazine (DKP) rings generating complex DKP-containing compounds, so far, a limited number of methyltransferases (MTs) co-occurring with CDPS have...
Unfortunately, the relevant techniques may not meet the mechanical requirements for load-bearing biomedical implants, particularly those implanted into bone, due to the high levels of abrasive and shear forces occurring at the implant-bone interface. Moreover, the PVD process is commonly utilized in ...
The following basic approaches are conceivable to identify the role of an infochemical: binding studies to the odorant-binding protein or to the odorant receptor binding protein (e.g., by in situ hybridization and immunohistochemical studies), measurement of electrical signals of the receptor cells ...
The study of the OH adsorption process on Pt single crystals is of paramount importance since this adsorbed species is considered the main intermediate in many electrochemical reactions of interest, in particular, those oxidation reactions that require a source of oxygen. So far, it is frequently ...
Nutraceuticals are naturally occurring compounds that have potential health benefits and are found in food sources such as fruits, vegetables, and herbs73. With the rise of chronic diseases such as diabetes, cardiovascular disease, and cancer, there is a growing interest in the use of ...
