Bacterial immune systems, such as CRISPR-Cas or restriction-modification (R-M) systems, affect bacterial pathogenicity and antibiotic resistance by modulating horizontal gene flow. A model system for CRISPR-Cas regulation, the Type I-E system from Escherichia coli, is silent under standard laboratory conditions and experimentally observing the dynamics of CRISPR-Cas activation is challenging. T...

BACKGROUND Despite evidence that childhood adversities (CAs) are associated with increased risk of mental disorders, little is known about their associations with disorder-related impairment. We report the associations between CAs and functional impairment associated with 12-month DSM-IV disorders in a national sample. METHOD We used data from the US National Comorbidity Survey Replication (N...

Voltage-gated Kv7 channels are inhibited by agonists of Gq-protein-coupled receptors, such as histamine. Recent works have provided evidence that inhibition of vascular Kv7 channels may trigger vessel contractions. In this study, we investigated how Kv7 activity modulates the histamine-induced contractions in "healthy" and metabolic syndrome (MetS) pig right coronary arteries (CAs). We performe...

Background and Purpose—To compare perioperative and midterm results of carotid artery stenting (CAS) versus carotid endarterectomy (CEA) in similar cohorts of patients, a retrospectively matched case-control study was performed. Methods—Three hundred and one case subjects undergoing CAS with cerebral protection and 301 concurrent matched-controls undergoing CEA were examined. Matching was by se...

STUDY DESIGN Retrospective cohort study. OBJECTIVE Several studies have shown that the accuracy of pedicle screw placement significantly improves with use of computer-assisted surgery (CAS). Yet few studies have compared the incidence of postoperative complications between CAS and conventional techniques. The objective of this study is to determine the difference in postoperative complication...

Physico-chemical and textural properties of foods in addition to their chemical composition modify postprandial metabolism and signals from the gastrointestinal tract. Enzymatic cross-linking of protein is a tool to modify food texture and structure without changing nutritional composition. We investigated the effects of structure modification of a milk protein-based model food and the type of ...

The central retinal artery (CRA), which can be non-invasively examined with ophthalmoscopy, may be regarded as an extracranial part of the cerebrovascular system. Assessment of CRA pressure may be of help in assessing the impediment of the intracranial blood circulation in patients with a carotid artery stenosis (CAS). The aim of this study was to explore the potential associations between dias...

A powerful contributor to prokaryotic evolution is horizontal gene transfer (HGT) through transformation, conjugation, and transduction, which can be advantageous, neutral, or detrimental to fitness. Bacteria and archaea control HGT and phage infection through CRISPR-Cas (clustered regularly interspaced short palindromic repeats-CRISPR-associated proteins) adaptive immunity. Although the benefi...
