An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

The Effects of Student Coaching in College: An Evaluation of a Randomized Experiment in Student Mentoring [PDF]

open access: yes
College completion and college success often lag behind college attendance. One theory as to why students do not succeed in college is that they lack key information about how to be successful or fail to act on the information that they have.

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Seven years at the coal-face: the retention phenomenon through the lens of a year tutor

open access: yes
Each year in higher education institutions around the world millions of people embark on degree level study. Unfortunately many of these hopefuls, for whatever reason, fail to progress to their second year of their course.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

An intelligent recommendation system framework for student relationship management

open access: yes, 2010
In order to enhance student satisfaction, many services have been provided in order to meet student needs. A recommendation system is a significant service which can be used to assist students in several ways.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

FOOTBALL AND FRESHMEN RETENTION: EXAMINING THE IMPACT OF COLLEGE FOOTBALL ON INSTITUTIONAL RETENTION RATES

open access: yes, 2010
Student retention has been one of the more researched topics in the study of American higher education over the past 20 years (Braxton, Hirschy, & McClendon, 2004; Pascarella & Terenzini, 2005).

Role of departmental support structures and self-efficacy on physics student persistence: An examination of students’ experience from 19 physics graduate programs

open access: yesPhysical Review Physics Education Research
Science, technology, engineering, and mathematics (STEM) graduate and doctoral programs experience consistently high attrition rates. Moreover, persistent disparities exist in gender and racial representation.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...
