The T structure of polycrystalline cubic human insulin.

The polymorphism of human insulin upon pH variation was characterized via X-ray powder diffraction, employing a crystallization protocol previously established for co-crystallization with phenolic derivatives. Two distinct rhombohedral (R3) polymorphs and one cubic (I23) polymorph were identified with increasing pH, corresponding to the T, TR and T conformations of insulin, respectively. The structure of the cubic T polymorph was determined via multi-profile stereochemically restrained Rietveld refinement at 2.

Peroneus longus acute calcific tendinitis: a case report.

Calcific tendinitis of the peroneus longus tendon is extremely rare, with only two cases described previously in the literature. Herein we discuss the diagnosis and management of a case with an acute calcific tendonitis of peroneus longus tendon.

Fascia iliaca block prophylaxis for hip fracture patients at risk for delirium: a randomized placebo-controlled study.

Background: Recent studies have indicated that unmanaged pain, both acute and chronic, can affect mental status and might precipitate delirium, especially in elderly patients with hip fractures. The aim of this study was to assess the effectiveness of fascia iliaca compartment block (FICB) for prevention of perioperative delirium in hip surgery patients who were at intermediate or high risk for this complication.

Materials And Methods: On admission, all included patients were divided into three groups according to low, intermediate or high risk for perioperative delirium.
