Exploring and Controlling Chemistry Using Quantum Logic.

Over the past years, the development of experimental techniques for the coherent manipulation and control of isolated quantum systems has made impressive progress. Such 'quantum-logic' methods are also highly attractive in a chemical context in view of unravelling and controlling the quantum dynamics of molecular collisions and chemical reactions. Quantum technologies have the potential to transform the way chemical dynamics are investigated - by providing highly sensitive methods for state readout and spectroscopy, by opening up new pathways for the quantum-state preparation of molecules and by enabling an improved control of their microscopic behavior on the single-particle level.

Novel antibodies detect nucleocytoplasmic O-fucose in protist pathogens, cellular slime molds, and plants.

Cellular adaptations to change often involve post-translational modifications of nuclear and cytoplasmic proteins. An example found in protists and plants is the modification of serine and threonine residues of dozens to hundreds of nucleocytoplasmic proteins with a single fucose (O-Fuc). A nucleocytoplasmic O-fucosyltransferase (OFT) occurs in the pathogen , the social amoeba , and higher plants, where it is called Spy because mutants have a spindly appearance.

Analysis of nitrogen-containing rocket fuel transformation products in loamy soil by thermal desorption gas chromatography-tandem mass spectrometry.

Unsymmetrical dimethylhydrazine (UDMH) based rocket fuel, when released into the soil, undergoes oxidative transformations to form a variety of toxic nitrogen-containing products (TPs). Loamy soils containing aluminosilicates (clay) are capable of strong binding and retention of UDMH TPs due to a combination of polar sorption and cation-exchange properties, posing challenges for their extraction and quantification. To overcome this problem, the present study proposes direct thermal desorption (TD) of analytes from loam facilitated by the addition of modifiers competing with UDMH TPs for sorption centers and ensuring their conversion into molecular form.

THE EFFECT OF MELATONIN ON THE SERUM LEVEL OF INTERLEUKIN 31 IN HERPESVIRUS SKIN DISEASES ON THE BACKGROUND OF HIV.

The immune system of the skin is the first line of defense against various infections, on the other hand, its strategic location as a key barrier between external and internal environment makes the skin an important tool for maintaining homeostasis, so dermatological lesions are often a manifestation of various pathological conditions. Thus, herpesvirus skin diseases, which are the result of reactivation of a latent infection and occur against the background of human immunodeficiency, may be the first manifestation of HIV. Active study of melatonin in recent years in the dermatological field is associated with interest in its biological action, which extends to the skin due to the melatoninergic system, and promising prospects for the development of new treatments.

Cholesteryl Ester Transfer Protein (CETP) Variations in Relation to Lipid Profiles and Cardiovascular Diseases: An Update.

Lipid metabolism plays an essential role in the pathogenesis of cardiovascular and metabolic diseases. Cholesteryl ester transfer protein (CETP) is a crucial glycoprotein involved in lipid metabolism by transferring cholesteryl esters (CE) and triglycerides (TG) between plasma lipoproteins. CETP activity results in reduced HDL-C and increased VLDL- and LDL-C concentrations, thus increasing the risk of cardiovascular and metabolic diseases.

Noncanonical interaction with microtubules via the N-terminal nonmotor domain is critical for the functions of a bidirectional kinesin.

Several kinesin-5 motors (kinesin-5s) exhibit bidirectional motility. The mechanism of such motility remains unknown. Bidirectional kinesin-5s share a long N-terminal nonmotor domain (NTnmd), absent in exclusively plus-end-directed kinesins.

Significance of Mitochondrial Dysfunction in the Pathogenesis of Parkinson's Disease.

Parkinson's disease (PD) is characterized by the degeneration of the dopaminergic neurons of the corpus striatum, which can be caused by the disruption of processes of mitochondrial homeostasis, including mitophagy, mitochondrial fusion and division, mitochondrial transport, accumulation of reactive oxygen species (ROS), and calcium signaling. Dopaminergic neurons are particularly vulnerable to mitochondrial dysfunction due to their polarized and expanded structure and high bioenergy needs. The molecular basis of these disorders is manifested in mutations of mitochondrial homeostasis proteins.
