Humans are expert tool users, who manipulate objects with dextrous hands and precise visual control. Surprisingly, morphological predispositions, or adaptations, for tool use have rarely been examined in non-human animals. New Caledonian crows Corvus moneduloides use their bills to craft complex tools from sticks, leaves and other materials, before inserting ...

Severe asthma affects 5 to 10% of the asthma population but consumes a disproportionate amount of the global asthma budget (∼50%) due to unscheduled health care utilization in primary care, hospitalizations due to severe exacerbations, and the costs of pharmacotherapy. A key challenge in managing severe asthma is to identify ...

A detailed stereo-mechanistic analysis has led to the design of a new tetradentate ligand for the enantioselective Ti(IV)-catalyzed oxidation of unsymmetrical sulfides to sulfoxides with high selectivity. The pathway of this oxidation and the closely related and long-known Kagan-Modena oxidation have been clarified to identify the likely origin of enantioselectivity.

BackgroundThe reabsorption of filtered plasma proteins, hormones and vitamins by the renal proximal tubules is vital for body homeostasis. Studies of megalin-deficient mice suggest that the large multi-ligand endocytic receptor megalin plays an essential role in this process. In humans, dysfunctional megalin causes the extremely rare Donnai-Barrow/Facio-Oculo-Acustico-Renal (DB/FOAR) syndrome characterized ...

The synthesis and structure-activity relationships associated with a series of 1,1-diarylethylene tubulin polymerization inhibitors and are described. The key step for their preparation involves a palladium-catalyzed coupling of N-arylsulfonylhydrazones with aryl halides, thus providing flexible and convergent access to tri- and tetrasubstituted 1,1-diarylolefins and related to isocombretastatin A-4 (isoCA-4). These ...

The generalized term 'peripheral vascular disease' (PVD) may be used to refer to vascular disorders in any non-coronary arterial bed. The more specific term 'peripheral arterial disease' (PAD) is used to refer to a more specific process, atherosclerotic disease of the lower extremities. PAD is common. Conservative estimates suggest more ...
