In simple epithelial cells, apical and basolat-eral proteins are sorted into separate vesicular carriers before delivery to the appropriate plasma membrane domains. To dissect the putative sorting machinery, we have solubilized Golgi-derived transport vesicles with the detergent CHAPS and shown that an apical marker, influenza haemagglutinin (HA), formed a(More)
We have used an in vitro assay to follow the proteins transferred from a donor to an acceptor upon fusion of early endosomes. The acceptor was a purified early endosomal fraction immunoisolated on beads and the donor was a metabolically-labeled early endosomal fraction in suspension. In the assay, both fractions were mixed in the presence of unlabeled(More)
The assembly of signalling molecules into macromolecular complexes (transducisomes) provides specificity, sensitivity and speed in intracellular signalling pathways. Rod photoreceptors in the eye contain an unusual set of glutamic-acid-rich proteins (GARPs) of unknown function. GARPs exist as two soluble forms, GARP1 and GARP2, and as a large cytoplasmic(More)
The Hamilton Rating Scale for depression (HDRS) has become the standard observer rating scale for depression, yet there are no adequate data from normal samples. The present study was carried out in northern Italy. The purposes were 1) to examine the ratings in normals and 2) to examine the scale's validity in the different language and culture. The scale(More)
A protein of Mr 100,000 (MVP100) is highly enriched in the electromotor system of electric rays. Biochemical analysis indicates that MVP100 is contained in the cholinergic nerve terminals of Torpedo electric organ as part of a large cytosolic complex. On sucrose density gradient centrifugation MVP100 comigrates with synaptic vesicles or synaptosomes. It can(More)
Here, we report the localization and characterization of BHKp23, a member of the p24 family of transmembrane proteins, in mammalian cells. We find that p23 is a major component of tubulovesicular membranes at the cis side of the Golgi complex (estimated density: 12,500 copies/micron2 membrane surface area, or approximately 30% of the total protein). Our(More)
Twenty subjects with chronic nightmares for 17.2 years mean duration were randomly divided into two groups: Rehearsal and Recording. At inception, subjects in both groups were instructed to write down their nightmares for one month. The Recording group received no other intervention. Rehearsal subjects received a single treatment group session teaching an(More)
We examined the onsets of comorbid psychiatric disorders in patients with panic disorder (PD) (N = 54). In 42 patients (77.8%), PD was preceded by another psychiatric condition (secondary PD group), while in 12 patients (22.2%), PD occurred first or was the only diagnosed mental disorder (primary PD group). Patients with primary and secondary PD did not(More)
Nightmare frequency and self-rated distress were assessed retrospectively in two groups of chronic nightmare sufferers 30 months after treatment. In the initial phase, the image group (N = 9) learned a cognitive-behavioral technique (imagery rehearsal) for the treatment of nightmares. They were taught in one group session to: (1) record a nightmare; (2)(More)
Proteome analysis has rapidly developed in the post-genome era and is now widely accepted as the complementary technology for genetic profiling. It has been shown to be a powerful tool for studying human diseases and for identifying novel prognostic, diagnostic and therapeutic markers. This review focuses on the identification of new biomarkers and(More)
