The genetic and epigenetic influences that are responsible for the establishment and maintenance of the unique phenotype of the extraocular muscles (EOMs) are poorly understood. A role for visual cues in shaping EOM maturation was assessed in rats by using two visual deprivation paradigms, dark rearing and monocular deprivation. Isoforms of the contractile protein myosin heavy chain (MHC) were ...
Mesophotic hard corals (MHC) are increasingly threatened by a growing number of anthropogenic stressors, including impacts from fishing, land-based sources of pollution, and ocean acidification. However, little is known about their geographic distributions (particularly around the Pacific islands) because it is logistically challenging and expensive to gather data in the 30 to 150 meter depth r...
A randomized, blinded, multicenter trial was conducted to compare fluconazole (800 mg per day) plus placebo with fluconazole plus amphotericin B (AmB) deoxycholate (0.7 mg/kg per day, with the placebo/AmB component given only for the first 5-6 days) as therapy for candidemia due to species other than Candida krusei in adults without neutropenia. A total of 219 patients met criteria for a modifi...
Vaccines are the greatest single instrument of prophylaxis against infectious diseases, with immeasurable benefits to human wellbeing. The accurate and reliable prediction of peptide-MHC binding is fundamental to the robust identification of T-cell epitopes and thus the successful design of peptide- and protein-based vaccines. The prediction of MHC class II peptide binding has hitherto proved r...
STUDY DESIGN A multicenter, retrospective cohort study. OBJECTIVE To evaluate clinical outcomes in patients with reintubation after anterior cervical spine surgery. METHODS A total of 8887 patients undergoing anterior cervical spine surgery were enrolled in the AOSpine North America Rare Complications of Cervical Spine Surgery study. Patients with or without complications after surgery were...
Multiple studies have demonstrated decreased recidivism and increased treatment engagement for individuals with serious mental illness involved in Mental Health Courts (MHC). However, the limited availability of social and fiscal resources requires an analysis of the relationship between a program's effectiveness and its costs. Outcome costs associated with a sample of 105 participants discharg...
Recent work has demonstrated that nonstimulatory endogenous peptides can enhance T cell recognition of antigen, but MHCI- and MHCII-restricted systems have generated very different results. MHCII-restricted TCRs need to interact with the nonstimulatory peptide-MHC (pMHC), showing peptide specificity for activation enhancers or coagonists. In contrast, the MHCI-restricted cells studied to date s...
CONTEXT Intensive early treatment for first-episode psychosis has been shown to be effective. It is unknown if the positive effects are sustained for 5 years. OBJECTIVE To determine the long-term effects of an intensive early-intervention program (OPUS) for first-episode psychotic patients. DESIGN Single-blinded, randomized, controlled clinical trial of 2 years of an intensive early-interve...
BACKGROUND In high-income countries, great disparities exist in the organizational characteristics of maternity health services. In Finland, primary maternity care is provided at communal maternity health clinics (MHC). At these MHCs there are public health nurses and general practitioners providing care. The structure of services in MHCs varies largely. MHCs are maintained independently or mer...
A well-conducted multicenter study needs to assure standardization, uniformity of procedures, high data quality, and collaboration across sites. This manuscript describes the organization and dynamics of multicenter studies, focusing on governance and administrative structures among countries of diverse cultures. The organizational structure of a multicenter study is described, and a system for...
