概括
重新分析质谱蛋白质组学数据揭示了重复使用的重大障碍,包括缺失的元数据和专有格式. 实施标准化数据包对于防止"数据坟墓"和确保科学可重复性至关重要.
科学领域:
- 蛋白质组学是指蛋白质组学.
- 生物信息学是一种生物信息学.
- 数据科学数据科学数据科学
背景情况:
- 公共蛋白质组学存储库包含大量的质谱数据.
- 这些数据中的大部分很难重复使用,从而造成创建.
- 数据坟墓的数据坟墓.
- 这阻碍了重新分析.
研究的目的:
- 评估公开可用的质谱蛋白质组学数据的重新分析性.
- 识别阻碍数据重复使用和可复制性的系统障碍.
- 提出改善数据可访问性和重新分析的解决方案.
主要方法:
- 一个研究生课程使用了基于R的通用工作流来重新分析来自Proteomics识别数据库的六个项目.
- 学生团队进行了识别,量化,规范化,归算和微分表达式分析.
- 结果与原始研究进行了比较,以确定差异和障碍.
主要成果:
- 系统性障碍包括缺少元数据标准,缺少诱集细节,专有软件输出,缺少光谱库/FASTA文件,模糊的参数,不一致的文件命名和不充分的复制.
- 这些缺陷导致了分析结果的显著差异 (例如,蛋白质计数,差异表达蛋白质).
- 可复制性取决于透明的元数据,开放的格式和可执行的分析来源,而不仅仅是仪器.

The nursing history captures and records the patient's health status, so that a care plan evolves to meet the patient's individual needs. The nursing health history is a part of the initial assessment. A comprehensive history covers all health dimensions and plays a significant role in the assessment process. A comprehensive history includes the patient's biographical information, reasons for seeking health care, expectations, present and past health history, medications, and...

Data Collection I

Data collection gathers information needed to make accurate judgments about a patient's present condition. During a health history interview, subjective data is collected from the patient, their caregivers, or family members, and objective data is collected through observations and physical assessment. Patients are the primary source of subjective data. Thus information gathered from patients through interviews, observations, and physical examination is primary data. Secondary sources of...

Data collection is a systematic method of obtaining, observing, measuring, and analyzing accurate information. An experimental study is a standard method of data collection that involves the manipulation of the samples by applying some form of treatment prior to data collection. It refers to manipulating one variable to determine its changes on another variable. The sample subjected to treatment is known as “experimental units.”

The systematic method of obtaining and analyzing accurate information of a population is called data collection. A survey is a standard method of data collection that involves collecting information from a target human population about their experience, opinion, or knowledge of a product, service, or process. The responses are recorded and interpreted. The most common survey examples are written questionnaires, face-to-face or telephonic conversations, focus groups, and electronic (e-mail or...

The physical assessment examines the patient for objective data that defines the patient's condition, and aids in formulating the nursing care plan. The purpose of physical assessment is a health status appraisal, which includes identifying health problems, and establishing a database for nursing intervention.
The principles to begin the physical assessment include conducting a comprehensive or problem-related history in a quiet, well-lit room, emphasizing privacy and comfort for the...

Data collection refers to a systematic way of obtaining, observing, measuring, and analyzing accurate information. Observational studies are one of the most widely used methods of data collection. It involves collecting data by observing the behavior and physical characteristics of a sample without making any modifications to the sample.
