Ribosomal control of translational fidelity in Podospora anserina: A suppressor and an antisuppressor affecting the paromomycin-induced misreading in vitro

Summary The hypersensitivity to paromomycin dis played by the su _1–60 suppressor, which was thought to be a ribosomal ambiguity mutation, was used to isolate a new antisuppressor, AS ₇₁. This antisuppressor is not specific for ribosomal suppressors, since it is able to act on putative tRNA-type suppressors. Compared to the wild-type, the AS _7-1 mutation produces an increased resistance to paromomycin. In addition, it was found to stop the sporulation process. In the polyuridylic acid-dependant assay, the paromomycin induced misreading was shown to be higher on su _1–60 ribosomes and lower on ribosomes from AS _7–1 mutant and AS _7S-1-su _1–60 double mutant than on wild-type ribosomes. These data confirm that su _1–60 and AS _7-1 mutants are ribosomal mutants involved in the control of translational fidelity.     

The Turner syndrome research registry: Creating equipoise between investigators and participants

To address knowledge gaps about Turner syndrome (TS) associated disease mechanisms, the Turner Syndrome Society of the United States created the Turner Syndrome Research Registry (TSRR), a patient‐powered registry for girls and women with TS. More than 600 participants, parents or guardians completed a 33‐item foundational survey that included questions about demographics, medical conditions, psychological conditions, sexuality, hormonal therapy, patient and provider knowledge about TS, and patient satisfaction. The TSRR platform is engineered to allow individuals living with rare conditions and investigators to work side‐by‐side. The purpose of this article is to introduce the concept, architecture, and currently available content of the TSRR, in anticipation of inviting proposals to utilize registry resources.

Some notes on uncertainty; Federal policy and innovation

The legislative background and current responsibilities of the new National Center for Health Care Technology (NCHCT) are discussed. The NCHCT's charge is to consider the stage of development, the actual or potential risks, costs and rate of use of health care technology. The role of Government in supporting new technologies, stimulating innovation and encouraging application of research products is considered. These issues are discussed in the context of the uncertainty inherent in planning and the formulation of public policy.     

Psychological Research with Pediatric Conditions: If We Specialize, Can We Generalize?

Considered threats to validity and generalizability of psychologicalresearch with pediatric populations and proposed ways to betterunderstand and manage these problems. Variation due to characteristicsof acute and chronic conditions (e.g., duration, severity, illnesscourse), settings and referral patterns, family environmentalcharacteristics, as well as investigators' decisions concerningcriteria and recruitment limit inferences concerning the impactof pediatric conditions on psychological development and generalizabilityof findings. These problems call for an expanded use of replication,cross-center, population-based, and theory-driven research.Scientific progress will be made by increasing dialogues andcollaboration among researchers concerning generalizabilityproblems and improving research training in epidemiologicalmethods, analysis of large-scale data sets, and meta-analysis.     

大学生性行为及性道德观发展研究

目的 了解当代大学生性行为及性道德观念的发展变化。方法 自制问卷，对全国9所高校的2000余名大学生进行调查，并用SPSS10．0对结果进行统计处理。结果 大学生性交行为发生率呈逐年上升趋势，且随年级上升而增加；大学生认可性交行为道德观的5个雏度，但各年级之间有差异；大学生边缘性行为和独自性行为发生率随年级显著上升，认可度也随年级增加而上升；大学生对同性性接触基本持排斥态度，但排斥态度则趋于下降。结论 大学生性行为和性道德随年级上升而明显变化，应加强学校教育和引导。

A Contextual Family/Systems Approach to Pediatric Psychology: Introduction to the Special Issue

Introduced the special issue on "Family System in PediatricPsychology" by organizing the papers around a series of themesrelevant to understanding families in pediatric psychology.Themes reflect the relationships between parent and child adjustment,family subsystems, legacies and traditions, social support systems,family interventions, the constancy of change in families, thechallenges of conducting longitudinal research, the inclusionof fathers, and the importance of a competency framework inpediatric family psychology. The paper concludes with recommendationsfor pediatric family psychology, including suggestions for increasingdiversity, expanding methodological approaches, and enhancingfamily competence.
