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

Respiratory muscle work and inspiratory muscle training on cytokines, oxidative stress and diaphragm fatigue in younger and older populations [PDF]

open access: yes, 2013
Increased respiratory muscle work is encountered during strenuous whole-body exercise, and at rest in older adults and those with pulmonary limitations such as chronic obstructive pulmonary disease (COPD).

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes

open access: yesFEBS Letters, EarlyView.
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics

Honey as an antiviral agent against respiratory syncytial virus [PDF]

open access: yes, 2011
Respiratory syncytial virus is the most frequent cause of hospitalization for viral respiratory infections in infants and young children worldwide. It also severely affects immunocompromised adults and the elderly, however, despite decades of efforts ...

Pulmonary restriction predicts long-term pulmonary impairment in people with HIV and tuberculosis

open access: yesBMC Pulmonary Medicine, 2021
Background While tuberculosis is considered a risk factor for chronic obstructive pulmonary disease, a restrictive pattern of pulmonary impairment may actually be more common among tuberculosis survivors.

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.

Low birth weight for gestation and airway function in infancy: exploring the fetal origins hypothesis [PDF]

open access: yes, 2004
Background: Poor fetal growth has been associated with impaired airway function in adult life, but evidence linking birth weight and airway function in early childhood is sparse.

AscF in the mycobacterial CIII–CIV supercomplex lacks metal and nucleotide binding but links malate oxidation to respiration

open access: yesFEBS Letters, EarlyView.
The mycobacterial CIII‐CIV respiratory supercomplex is an obligate assembly, encompassing several subunits of unknown functions. We have characterized the intracellular subunit AscF, and show that it is unlikely to be a sensor for metals or nucleotides, but is required for growth on nonfermentable energy sources, and likely works as an adapter for ...

Respiratory allergy and asthma associated with pesticide exposure amongst women in rural Western Cape [PDF]

open access: yes, 2012
Includes bibliographical references.Pesticide exposure has been increasingly associated with adverse respiratory health effects including asthma and allergy. However, few studies have been conducted among women and workers in developing countries.
