Using alteplase nephrostomy tube installation for thrombolysis of ureter tract clot obstruction.

In literature, few cases have been reported regarding the use of alteplase installation in a nephrostomy as anticoagulant treatment of blood clots in the upper urinary tract. Our case -report provides a unique case of alteplase installation in the nephrostomy tube for thrombolysis of a blood clot formation in the upper ureter. The blood clot formation emerged as acute obstruction following a planned endoscopic lithotripsy.

Dentate granule cell recruitment of feedforward inhibition governs engram maintenance and remote memory generalization.

Memories become less precise and generalized over time as memory traces reorganize in hippocampal-cortical networks. Increased time-dependent loss of memory precision is characterized by an overgeneralization of fear in individuals with post-traumatic stress disorder (PTSD) or age-related cognitive impairments. In the hippocampal dentate gyrus (DG), memories are thought to be encoded by so-called 'engram-bearing' dentate granule cells (eDGCs).

Spinal GABAergic mechanisms in the effects of spinal cord stimulation in a rodent model of neuropathic pain: is GABA synthesis involved?

Objectives: The effects of spinal cord stimulation (SCS) on the spinal γ-amino butyric acid (GABA) system have previously been studied in animal models of neuropathic pain. These studies, confirming the pivotal role of segmental GABA actions for the efficacy of SCS, have led to the question if the disturbance of the GABA inhibitory system as demonstrated both in basal and clinical studies also encompasses malfunction of the GABA synthesis.

Methods: Rat models of neuropathic pain were submitted to SCS applied with "clinical SCS parameters.
