#1
Clemens Richert, Elena Hänle
All known forms of life encode their genetic information in a sequence of bases of a genetic polymer and produce copies of their genes via semiconservative replication. How this process started before polymerase enzymes had been evolved is unclear. Enzyme-free copying of short stretches of DNA or RNA sequence has been demonstrated, using activated nucleotides, but not replication. We have developed a methodology for replication. It involves extension with reversible termination, enzyme-free ligation, and strand capture and allowed us to monitor nucleotide incorporation for an entire helical turn of DNA, both during a first and a second round of copying...

BACKGROUND: Clinical pharmacists play an increasing role in the pharmacological treatment of hospital-admitted older patients with dementia or cognitive impairment. In an earlier randomised controlled trial, clinical pharmacist involvement in the ward team could significantly reduce drug-related readmissions in patient subgroups. However, the economic impact of the intervention has not been addressed so far. OBJECTIVES: To evaluate the economic impact of clinical pharmacist engagement in hospital ward teams for medication therapy management in older patients with dementia or cognitive impairments...

OBJECTIVES: For hospitalizations in rehabilitation centers (RCs) in France, the quantification of healthcare givers' activity is based on the dependency of the patients, defined as a total or partial inability to perform activities required for daily living without help. The tools currently used to quantify dependency are not sufficiently precise. Here we describe the construction of a new tool, the SOFMER Activity Score (SAS scoring), which allows for a good description of the level of activity of patients hospitalized in RCs, and a feasibility study of the tool...

BACKGROUND: We initiated a research program to develop a novel patient-reported outcome measure (PROM) to assess postoperative recovery from the perspective of abdominal surgery patients. In light of FDA recommendations, the first stage of our program aimed to, based on previous literature and expert input, develop a hypothesized conceptual framework portraying the health domains that are potentially relevant to the process of recovery after abdominal surgery. METHODS: This study was conducted in three phases: (1) systematic review to identify PROMs with measurement properties appraised in the context of recovery after abdominal surgery, (2) content analysis to categorize the health domains covered by the PROMs according to the ICF, and (3) two-round Delphi study to gain expert input regarding which of these health domains are relevant to the process of recovery...

Unspecific peroxygenase (UPO) is a highly promiscuous biocatalyst and its selective mono(per)oxygenase activity makes it useful for many synthetic chemistry applications. Among the broad repertory of library creation methods for directed enzyme evolution, genetic drift allows neutral mutations to be accumulated gradually within a polymorphic network of variants. In this study, we conducted a campaign of genetic drift with UPO in Saccharomyces cerevisiae so that neutral mutations were simply added and recombined in vivo With low mutational loading and an activity threshold of 45% of the parent's native function, mutant libraries enriched in folded and active UPO variants were generated...

BACKGROUND: Self-care behaviors are commonly prescribed to manage both cardiovascular disease and hypertension to reduce modifiable risk factors and improve quality of life. Nevertheless, long-term adherence to self-care recommendations for cardiac patients has been problematic. In cardiac patients, moderated online forums have been found to be particularly useful in supporting maintenance of heart-healthy diet and fewer hospital visits. As such, we developed the e-Forum, a Web-based moderated forum designed to promote continued user engagement and long-term self-care adherence...

INTRODUCTION: Low-dose computed tomography (LDCT) lung cancer screening is recommended in the United States. While new solid nodules after baseline screening have a high lung cancer probability at small size and require lower size cutoff values than baseline nodules, there only is limited evidence on management of new subsolid nodules. METHODS: Within the Dutch-Belgian randomized controlled LDCT lung cancer screening trial (NELSON), 7557 participants underwent baseline screening between April 2004 and December 2006...

Zhidong Gao, Kewei Jiang, Yingjiang Ye, Shan Wang
Gastric stump cancer(GSC) is defined as newly developed remnant stomach cancer following gastrectomy. This definition initially referred to carcinoma detected in the remnant stomach more than 5 years after the primary surgery for a benign disease. Subsequently, this timeframe was extended to 10 years after the primary surgery for a malignant disease. Recently, the concept of "carcinoma in the remnant stomach(CRS)" proposed by the Japanese Gastric Cancer Association was introduced in China. The new definition encompasses all carcinomas arising in the remnant stomach following gastrectomy, irrespective of the histology of the primary lesion, extent of resection, or reconstruction method...
