Impaired recollection and initially preserved familiarity in a patient with bilateral fornix transection following third ventricle colloid cyst removal: A two-year follow-up study.

Objective: Recognition memory is widely accepted as a dual process-based model, namely familiarity and recollection. However, the location of their specific neurobiological substrates remains unclear. Similar to hippocampal damage, fornix damage has been associated with recollection memory but not familiarity memory deficits.

Cortical cells are altered by factors including bone morphogenetic protein released from a placental barrier model under altered oxygenation.

Episodes of hypoxia and hypoxia/reoxygenation during foetal development have been associated with increased risk of neurodevelopmental conditions presenting in later life. The mechanism for this is not understood; however, several authors have suggested that the placenta plays an important role. Previously we found both placentas from a maternal hypoxia model and pre-eclamptic placentas from patients release factors lead to a loss of dendrite complexity in rodent neurons.

Secretions from placenta, after hypoxia/reoxygenation, can damage developing neurones of brain under experimental conditions.

Some psychiatric diseases in children and young adults are thought to originate from adverse exposures during foetal life, including hypoxia and hypoxia/reoxygenation. The mechanism is not understood. Several authors have emphasised that the placenta is likely to play an important role as the key interface between mother and foetus.

Changes of performance monitoring with learning in older and younger adults.

This study examined age differences in performance monitoring during learning of a stimulus-response association task. At the beginning of the learning process, amplitudes of the response-locked error-related negativity (ERN or Ne) and correct response-related negativity (CRN) did not differ in both age groups. With advanced learning the response ERN/Ne increased and the CRN decreased in younger adults, but did not dissociate in older adults.

Inhibition of both neutral endopeptidase and endothelin-converting enzyme by SLV306 reduces proteinuria and urinary albumin excretion in diabetic rats.

Diabetic nephropathy is a serious complication of diabetes associated with a poor prognosis which deteriorates to end-stage renal disease. Increased urinary excretion of protein and albumin are early clinical markers for diabetic renal disease and increased risk of cardiovascular disease. Diabetes causes activation of the renal endothelin system inducing renal damage.

Systemic cardiovascular disease in uremic rats induced by 1,25(OH)2D3.

Objective: Vitamin D may contribute to cardiovascular disease in the absence of hypercalcemia in patients with chronic kidney disease.

Methods: We investigated the effects of long-term (6-week) treatment with 1,25(OH)2D3, at a non-hypercalcemic dosage (0.25 microg/kg per day per orally) in 5/6 nephrectomized rats: (i) vehicle-treated, sham-operated rats; (ii) 1,25(OH)2D3-treated, sham-operated rats; (iii) vehicle-treated, 5/6 nephrectomized rats; and (iv) 1,25(OH)2D3-treated, 5/6 nephrectomized rats.
