question:
Psoriasis profoundly affects patient quality of life (QOL). Amevive (alefacept), a novel and selective biologic agent, was clinically effective and significantly improved QOL in a phase 2 study.', 'The present placebo-controlled, randomized phase 3 study examined the effects of a 12-week course of intramuscular alefacept on QOL in 507 patients with chronic plaque psoriasis using both dermatology-specific questionnaires [Dermatology Life Quality Index (DLQI); Dermatology Quality of Life Scales (DQOLS)] and the Short Form-36 Health Survey (SF-36), a generic, general health questionnaire.', 'All 3 QOL measures (DLQI, DQOLS, SF-36) demonstrated that alefacept 15 mg was significantly more effective than placebo in improving QOL in patients with chronic plaque psoriasis. In addition, the improvements in QOL for patients in the alefacept 15 mg group were of similar magnitude for all 3 QOL measures.
answer:
Does intramuscular alefacept improve health-related quality of life in patients with chronic plaque psoriasis?


question:
To fully understand the cytotoxicity of after-degradation QDs, we synthesized CdS QDs and investigated its toxicity mechanism.', 'Biomimetic method was proposed to synthesize cadmium sulfide (CdS) QDs. Thereafter MTT (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide) assay was conducted to evaluate their cytotoxicity. To investigate the toxicity mechanism, we subsequently conducted intracellular reactive oxygen species (ROS) measurement with DCFH-DA, glutathione (GSH) measurement with DTNB, and cellular cadmium assay using atomic absorption spectrometer. Microsized CdS were simultaneously tested as a comparison.', "MTT assay results indicated that CdS QDs are more toxic than microsized CdS especially at concentrations below 40 microg/ml. While microsized CdS did not trigger ROS elevation, CdS QDs increase ROS by 20-30% over control levels. However, they both deplete cellular GSH significantly at the medium concentration of 20 microg/ml. In the presence of NAC, cells are partially protected from CdS QDs, but not from microsized particles. Additionally, nearly 20% of cadmium was released from CdS nanoparticles within 24h, which also accounts for QDs' toxicity.
answer:
Do intracellular oxidative stress and cadmium ions release induce cytotoxicity of unmodified cadmium sulfide quantum dots?


question:
Congenital factor VII (FVII) and factor X (FX) deficiencies belong to the group of rare bleeding disorders which may occur in separate or combined forms since both the F7 and F10 genes are located in close proximity on the distal long arm of chromosome 13 (13q34). We here present data of 192 consecutive index cases with FVII and/or FX deficiency. 10 novel and 53 recurrent sequence alterations were identified in the F7 gene and 5 novel as well as 11\xa0recurrent in the F10 gene including one homozygous 4.35\xa0kb deletion within F7 (c.64+430_131-6delinsTCGTAA) and three large heterozygous deletions involving both the F7 and F10 genes. One of the latter proved to be cytogenetically visible as a chromosome 13q34 deletion and associated with agenesis of the corpus callosum and psychomotor retardation.
answer:

Do large deletions play a minor but essential role in congenital coagulation factor VII and X deficiencies?
