Fatigue and cognitive symptoms in patients with diabetes: relationship with disease phenotype and insulin treatment.

Neurobehavioral symptoms are frequently reported in patients with diabetes. Nevertheless, the characterization of the specific symptom dimensions that develop in diabetic patients with respect to disease phenotype and treatment status remains obscure. This study comparatively assessed fatigue symptoms and cognitive performance using a dimensional approach in 21 patients with insulin-treated type 1 diabetes, 24 type 2 diabetic patients either insulin-free or undergoing insulin treatment for at least six months, and 15 healthy subjects.

Polyvalent degenerate oligonucleotides reverse transcription-polymerase chain reaction: a polyvalent detection and characterization tool for trichoviruses, capilloviruses, and foveaviruses.

ABSTRACT A polyvalent nested reverse transcription-polymerase chain reaction (RT-PCR) test using degenerate primers containing inosine (polyvalent degenerate oligonucleotides [PDO]) was developed for filamentous fruit tree viruses belonging to the genera Trichovirus, Capillovirus, and Foveavirus. The 362-bp product was amplified from nucleic acid extracts obtained from Prunus and Malus leaf samples. All the viruses targeted were detected, demonstrating the polyvalence of the test.

Host species-dependent population structure of a pollen-borne plant virus, Cherry leaf roll virus.

Cherry leaf roll virus (CLRV) belongs to the Nepovirus genus within the family Comoviridae. It has a host range which includes a number of wild tree and shrub species. The serological and molecular diversity of CLRV was assessed using a collection of isolates and samples recovered from woody and herbaceous host plants from different geographical origins.
