Depression following hip fracture is associated with increased physical frailty in older adults: the role of the cortisol: dehydroepiandrosterone sulphate ratio [PDF]

, 2013
BackgroundHip fracture in older adults is associated with depression and frailty. This study examined the synergistic effects of depression and hip fracture on physical frailty, and the mediating role of the cortisol:dehydroepiandrosterone sulphate ...

Depressed Fracture of Calvarial Bone following Rapid Scalp Expansion for Post-burn Alopecia in a Child

Indian Journal of Plastic Surgery, 2001
Depressed calvarial fracture as a complication of scalp expansion in a 3 1/2-year-old girl who underwent 8cm scalp expansion over 48 days is being reported. A technique for placement of tissue expander through multiple small radically placed incisions is

Arthroscopic Reduction and Fixation of Impacted Humeral Head Reverse Hill‐Sachs Fracture With Absorbable Anchors for Acute Traumatic Posterior Shoulder Dislocation [PDF]

Arthrosc Tech
Abstract A minimally invasive technique is presented for the treatment of acute traumatic posterior shoulder dislocation with a reverse Hill‐Sachs lesion. Arthroscopic reduction was combined with internal fixation using 1 absorbable anchor. Under high‐definition arthroscopic visualization, precise anatomical reduction of the impacted anteromedial ...

Bio‐Inspired Oligocellulose‐Regulated Ice‐Water Interfaces Enable Sustained Ion Transport in Frozen Aqueous Zinc Batteries

Advanced Science, EarlyView.
Inspired by antifreeze glycoproteins (AFGPs), we synthesized a type of oligomeric cellulose (OC‐8) to inhibit ice formation and enlarge the inter‐ice water channel for transportation. Typical confocal fluorescence experiments display the expansion of the ice‐water interface for zinc‐ion transport.

Multiscale modelling of materials chemomechanics : brittle fracture of oxides and semiconductors [PDF]

, 2014
Fracture is one of the most challenging ‘multi-scale’ problems to model: since crack propagation is driven by the concentration of a long-range stress field at an atomically sharp crack tip, an accurate description of the chemical processes occurring in ...

Inverted Steinmann pin technique: Simple and effective method for elevation of lateral tibial plateau depressed fractures (Schatzker type III)

Journal of Orthopaedic Reports
One may observe depressed tibial plateau fractures alone or in conjunction with intricate proximal tibia fractures. Traditionally, in complex fractures, the depressed fragment can be elevated by passing a bone tamp through the fracture itself.

Targeting β2‐Adrenergic Receptor Stability With Lycorine Reveals a Host‐Directed Pathway for Antiviral Defense Against Poxviruses

Advanced Science, EarlyView.
Chronic stress drives autophagy‐mediated β2‐AR degradation, impairing antiviral immunity and promoting poxvirus lethality. Lycorine directly stabilizes β2‐AR to restore host defense, suppress excessive inflammation and improve survival. ABSTRACT Psychological stress is a pervasive yet poorly understood modulator of infectious disease outcomes. Here, we
