There is a significant gap in understanding the risk of sexual victimization in individuals with autism spectrum disorders (ASD) and the variables that contribute to risk. Age appropriate sexual interest, limited sexual knowledge and experiences, and social deficits, may place adults with ASD at increased risk. Ninety-five adults with ASD and 117 adults without ASD completed questionnaires regarding sexual knowledge sources, actual knowledge, perceived knowledge, and sexual victimization. Individuals with ASD obtained less of their sexual knowledge from social sources, more sexual knowledge from non-social sources, had less perceived and actual knowledge, and experienced more sexual victimization than controls. The increased risk of victimization by individuals with ASD was partially mediated by their actual knowledge. The link between knowledge and victimization has important clinical implications for interventions. 相似文献

A PEGylated glucagon-like peptide-1 (GLP-1) agonist and glucagon antagonist hybrid peptide was engineered as a potential treatment for type 2 diabetes. To support preclinical development of this PEGylated dual-acting peptide for diabetes (DAPD), we developed a reproducible method for PEGylation, purification, and analysis. Optimal conditions for site-specific PEGylation with 22 and 43 kDa maleimide-polyethylene glycol (maleimide-PEG) polymers were identified by evaluating pH, reaction time, and reactant molar ratio parameters. A 3-step purification process was developed and successfully implemented to purify PEGylated DAPD and remove excess uncoupled PEG and free peptide. Five lots of 43 kDa PEGylated DAPD with starting peptide amounts of 100 mg were produced with overall yields of 53% to 71%. Analytical characterization by N-terminal sequencing, amino acid analysis, matrix-assisted laser desorption/ionization mass spectrometry, and GLP-1 receptor activation assay confirmed site-specific attachment of PEG at the engineered cysteine residue, expected molecular weight, correct amino acid sequence and composition, and consistent functional activity. Purity and safety analysis by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), analytical ion-exchange chromatography, reversed-phase high-performance liquid chromatography, and limulus amebocyte lysate test showed that the final products contained <1% free peptide, <5% uncoupled PEG, and <0.2 endotoxin units per milligram of peptide. These results demonstrate that the PEGylation and purification process we developed was consistent and effective in producing PEGylated DAPD preclinical materials at the 100 mg (peptide weight basis) or 1.2 g (drug substance weight basis) scale. 相似文献

The goal of this study was to evaluate the efficacy of a cognitive-behavioral treatment package for comorbid generalized anxiety disorder (GAD) and panic disorder with agoraphobia (PDA). A single-case, multiple-baseline, across-subjects design was used with 3 primary GAD patients with secondary PDA. The efficacy of the treatment was evaluated with a structured interview, a battery of self-report questionnaires, and daily self-monitoring booklets. Results are promising: At posttreatment, 2 out of 3 participants achieved high endstate functioning and maintained this level at 3-, 6-, and 12-month follow-ups. The 3rd participant also improved but achieved moderate endstate functioning. The strengths and limitations of the treatment are discussed. 相似文献
