ABSTRACT: Historians recognize Adolf Meyer (1866-1950), first psychiatrist-in-chief at Johns Hopkins Hospital, as one of the principal architects of clinical psychiatry in the United States. This wholesale influence on the fledgling discipline had much to do with the authority he wielded as a Hopkins chief, but an important question remains: ...

Regulation of organ size is achieved through the action of the mTOR and Hippo signalling pathways, which control cell proliferation and cell growth in response to extracellular cues. A link between these pathways is revealed by the finding that YAP downregulates PTEN to promote cell growth and tissue hyperplasia.

Basal cell carcinoma has been shown to originate from activation of hedgehog signalling in interfollicular epidermal progenitor cells. Analyses of the early steps of basal cell carcinoma formation show that this process requires reprogramming of interfolliclular epidermal cells to an embryonic hair follicle progenitor-like fate, with concomitant Wnt pathway activation.

Plaque elasticity (i.e., modulogram) and morphology are good predictors of plaque vulnerability. Recently, our group developed an intravascular ultrasound (IVUS) elasticity reconstruction method which was successfully implemented in vitro using vessel phantoms. In vivo IVUS modulography, however, remains a major challenge as the motion of the heart prevents accurate strain field estimation. ...

BK virus nephropathy (BKVN) is among the most important problems in renal transplant recipients. This report presented an assessment of treatment with a fluoroquinolone antibiotic, ciprofloxacin, for 6 months in a 21-year-old male patient who developed BKVN after transplantation. Ciprofloxacin treatment reduced the viral load and improved the clinical findings.
