Substituted 3-imidazo[1,2-a]pyridin-3-yl- 4-(1,2,3,4-tetrahydro-[1,4]diazepino-[6,7,1-hi]indol-7-yl)pyrrole-2,5-diones as highly selective and potent inhibitors of glycogen synthase kinase-3.

Glycogen synthase kinase-3 (GSK3) is involved in signaling from the insulin receptor. Inhibitors of GSK3 are expected to effect lowering of plasma glucose similar to insulin, making GSK3 an attractive target for the treatment of type 2 diabetes. Herein we report the discovery of a series of potent and selective GSK3 inhibitors.

Surgical management of dissociated motor loss following complex cervical spine reconstruction.

Study Design: A case of surgical management of dissociated motor loss after decompression of the cervical spine is reported.

Objectives: To present a rationale for surgical treatment of postdecompressive cervical radiculopathy with an illustrative case example.

Summary Of Background Data: The unusual complication of radiculopathy after multilevel cervical decompressive procedures is characterized by pain or dissociated motor weakness of the C5 and C6 nerve roots.

Mutations in INVS encoding inversin cause nephronophthisis type 2, linking renal cystic disease to the function of primary cilia and left-right axis determination.

Nephronophthisis (NPHP), an autosomal recessive cystic kidney disease, leads to chronic renal failure in children. The genes mutated in NPHP1 and NPHP4 have been identified, and a gene locus associated with infantile nephronophthisis (NPHP2) was mapped. The kidney phenotype of NPHP2 combines clinical features of NPHP and polycystic kidney disease (PKD).

Villous hypertrophy versus choroid plexus papilloma: a case report demonstrating a diagnostic role for the proliferation index.

Diffuse bilateral enlargement of the choroid plexus has long been appreciated as a cause of shunt-resistant hydrocephalus in infants, most often secondary to cerebrospinal fluid overproduction. Despite the fact that such lesions have interchangeably been termed 'villous hypertrophy' (VH) or 'bilateral choroid plexus papilloma' (CPP), little attention has been paid to the pathological distinctions that characterize these two entities. We present a case of presumed VH in a 2-week-old female presenting with cerebrospinal fluid production-dependent hydrocephalus that ultimately required bilateral surgical ablation of the choroid plexus.

Midline ventral intradural schwannoma of the cervical spinal cord resected via anterior corpectomy with reconstruction: technical case report and review of the literature.

Objective And Importance: Spinal cord schwannomas are intradural nerve sheath tumors that almost universally occupy a dorsolateral, lateral, or ventrolateral position. Therefore, resection of these lesions typically proceeds via a posterior or posterolateral approach.

Clinical Presentation: We present a case of a midline ventral intradural schwannoma of the cervical spinal cord causing myelopathy.

Advances in plant biotechnology and its adoption in developing countries.

Developing countries are already benefiting and should continue to benefit significantly from advances in plant biotechnology. Insect-protected cotton containing a natural insecticide protein from Bacillus thuringiensis (Bt cotton) is providing millions of farmers with increased yields, reduced insecticide costs and fewer health risks. Many other useful plant biotechnology products that can benefit poor farmers and consumers are in the research and development pipelines of institutions in developing countries, and should soon reach farmers' fields.

Traumatic aortic transection: evidence for the osseous pinch mechanism.

Acute traumatic transection of the thoracic aorta is most commonly seen in vehicular trauma and is generally accepted to be due to differential deceleration. A second mechanism is proposed for this injury and that is the osseous pinch mechanism. We report a case where aortic transection occurred due to a crush injury and supports the latter mechanism.
