The paper outlines a new mode of intravascular anabolic steroidal transport. The single intravenous administration of metandrostenolone aqueous solution to rats increases hypertrophy rate of MM. plantaris. It was shown that the action of a single dose (0.05 mg/kg) exceeded that of metandrostenolone oil solution in a dose of 5 mg/kg. The multiple reduction of doses of the anabolic drug and the high level of bioavailability were achieved. This effect was explained by the application of the specific transport agent.

Intensified host-guest electronic interplay within stable metal-organic cages (MOCs) presents great opportunities for applications in stimuli response and photocatalysis. Zr-MOCs represent a type of robust discrete hosts for such a design, but their host-guest chemistry in solution is hampered by the limited solubility. Here, by using pyridinium-derived cationic ligands with tetrakis(3,5-bis(trifluoromethyl)phenyl)borate (BAr) as solubilizing counteranions, we report the preparation of soluble Zr-MOCs of different shapes (1-4) that are otherwise inaccessible through a conventional method.

Background: Iron is implicated in Alzheimer's disease (AD) and is bound to β-amyloid (Ab) plaques. AD brains have increased 4-hydroxynonenal (HNE) adducts, a lipid decomposition product bound to proteins originating from iron mediated lipid peroxidation. Increased brain iron may result from cerebral microbleeds which by nature are rich sources of iron.

Membrane proteins play a crucial role in a variety of biological processes and are key targets for pharmaceutical development. Structural studies of membrane proteins provide molecular insights into the mechanisms of these processes and are essential for effective drug discovery. Historically, these studies have relied on solubilization of the target protein using detergents, but conventional detergents often fail to maintain the stability of challenging membrane proteins.

Aims: The sand-fixing desert shrub Artemisia sphaerocephala produces a large amount of seed mucilage, which plays crucial roles in the adaptation of this species to desert environments. Seed mucilage has been shown to be degraded by Phanerochaete chrysosporium from habitat soils, but the process and products of this degradation remain unclear. To fill this gap, we explored the factors and processes involved in mucilage degradation.

Cyclodextrins are widely used pharmaceutical excipients known to increase the solubility of drug compounds through formation of inclusion complexes. A prominent limitation of common cyclodextrins is their own scarce solubility in water, which renders them unsuitable for many drug formulations. Cyclodextrin solubility can be enhanced in appropriate media such as Deep Eutectic Solvents (DESs).
