Vascular endothelial growth factor (VEGF-A) is a major regulator of blood vessel formation and function. It controls several processes in endothelial cells, such as proliferation, survival, and migration, but it is not known how these are coordinately regulated to result in more complex morphogenetic events, such as tubular sprouting, fusion, and network(More)
To investigate whether the enhancement of thick ascending limb (TAL) NaCl transport in response to long-term increases in circulating vasopressin concentration is associated with increased expression levels of the apical Na-K-2Cl cotransporter in the rat TAL, we have carried out immunoblotting and immunofluorescence studies using affinity-purified,(More)
A tone-on-tone masking paradigm was used to determine tuning curves of cochlear and brainstem responses in the guinea pig. The tuning curves are considered to be a measure of the frequency specificity of these potentials. Calculated Q10 values are used in an indicator of the sharpness of tuning of these potentials. The tuning curves of cochlear and(More)
We describe a 30-year-old pregnant woman with undiagnosed weakness who delivered a severely weak neonate. Subsequent workup of the mother revealed myasthenia gravis with muscle-specific kinase antibodies. The infant responded to intravenous immunoglobulin and symptoms normalized. He was presumed to have an anti-muscle-specific kinase-mediated transient(More)
Dermatomyositis is an autoimmune disorder that causes proximal muscle weakness and skin changes which include generalized erythema, heliotrope rash and/or Gottron's papules. Generalized or limb edema is an uncommon manifestation of dermatomyositis. Here, we report four cases who presented with generalized or limb edema, proximal muscle weakness,(More)
