Congenital disorders of glycosylation (CDG) are a group of clinically heterogeneous inborn errors of metabolism. At present, treatment is available for only one CDG, but potential treatments for the other CDG are on the horizon. It will be vitally important in clinical trials of such agents to have a clear understanding of both the natural history of CDG and the?corresponding burden of disability suffered by patients. To date, no multicentre studies have attempted to document the natural history of CDG. This is in part due to the lack of a reliable assessment tool to score CDG's diverse clinical spectrum. Based on our earlier experience evaluating disease progression in disorders of oxidative phosphorylation, we developed a practical and semi-quantitative rating scale for children with CDG. The Nijmegen Paediatric CDG Rating Scale (NPCRS) has been validated in 12 children, offering a tool to objectively monitor disease progression. We undertook a successful trial of the NPCRS with a collaboration of nine experienced physicians, using video records of physical and neurological examination of patients. The use of NPCRS can facilitate both longitudinal and natural history studies that will be essential for future interventions. 相似文献

A library of 21 new N-Mannich bases of 3,3-diphenyl- (5a-g), 3-methyl-3-phenyl- (6a-g), and 3-ethyl-3-methylpyrrolidine-2,5-diones (7a-g) were synthesized and evaluated for their anticonvulsant activity in the maximum electroshock (MES) and subcutaneous pentylenetetrazole (scPTZ) seizure tests after intraperitoneal injection into mice. The acute neurological toxicity was determined applying the rotarod screen. The results in mice showed that 13 compounds were effective in the MES or/and scPTZ screen. From these, seven molecules were tested in the MES seizures after oral administration in rats. The quantitative studies showed that N-[{4-(2-hydroxyethyl)-piperazin-1-yl}-methyl]-3-methyl-3-phenylpyrrolidine-2,5-dione (6c) and N-[(4-benzylpiperidin-1-yl)-methyl]-3-methyl-3-phenylpyrrolidine-2,5-dione (6f) revealed higher protection in the MES and scPTZ tests than valproic acid or ethosuximide which were used as reference antiepileptic drugs. Four compounds (5c, 6c, 6e, 6f) showed high effectiveness in the 6-Hz psychomotor seizure model of partial and therapy resistant epilepsy. 相似文献

We examined the effect of selected anthraquinone antitumour agents - doxorubicin (DOX), pirarubicin (PIRA) and benzoperimidine BP1 - on inducing apoptosis of the sensitive leukaemia HL60 cell line and its multidrug resistance sublines overexpressing P-glycoprotein (HL60/VINC) and multidrug resistance-associated protein 1 (HL60/DOX). All agents used at IC50 and IC90 were able to influence the cell cycle of sensitive HL60 and resistant cells and induce apoptosis. Interestingly, it was seen that HL60/VINC cells were more susceptible to undergo caspase-3/caspase-8-dependent apoptosis induced by the studied anthraquinone compounds compared with HL60 and HL60/DOX cells. However, the examined agents did not change the expression of Fas receptors on the surface of HL60-sensitive and-resistant cells. 相似文献

The aims of this study were to assess the prevalence of paraneoplastic rheumatic syndromes in a cohort of patients with newly
diagnosed solid tumours and to describe their autoimmune profile, comparing it to the controls. Screening questionnaires (3,770)
were distributed, and during a three-step study, 94 patients were confirmed to have both paraneoplastic syndrome and oncology
diagnoses. Three control groups–patients with undifferentiated arthritis, Raynaud's phenomenon for non-malignant causes and
solid tumours only–were designed to compare with the paraneoplastic cases and their immunology profile. The prevalence of
paraneoplastic rheumatic syndromes was 2.65% (95% CI 0.21–3.20). The group of patients with arthritis and the group of patients
with Raynaud's syndrome were found to prevail among other clinical presentations of paraneoplastic rheumatic syndromes. Both
paraneoplastic syndromes were linked to malignancies of the urogenital system. Antinuclear antibodies were found to be similarly
frequent in the paraneoplastic arthritis, paraneoplastic Raynaud's phenomenon and the solid tumour groups. No differences
were observed when comparing paraneoplastic arthritis and undifferentiated arthritis, except that the patients with paraneoplastic
arthritis were older. Comparing paraneoplastic Raynaud's to Raynaud's phenomenon, male preponderance in the paraneoplastic
Raynaud's phenomenon group was observed, and the patients were obviously older. Paraneoplastic rheumatic syndromes are rare
and more often occur in older patients. Among them, paraneoplastic arthritis and Raynaud's syndrome were the most frequent.
The immunology profile does not help in discriminating between arthritis and paraneoplastic arthritis patients and is of limited
use in Raynaud's differential diagnosis. 相似文献
