Variability of selected indicators of physical activity in a randomized sample of the Czech population between the years 2003–2006: Results from the short and long self administered format of the IPAQ questionnaire [Variabilita vybraných indikátorů pohybové aktivity u randomizovaných souborů české populace v letech 2003–2006: Výsledky z krátké a dlouhé administrativní verze IPAQ dotazníku]

Acta Universitatis Palackianae Olomucensis. Gymnica, 2009
BACKGROUND: The effort to gain worldwide data on the levels of physical activity (PA) of different populations, which would be comparable, led to the creation and standardization of the International Physical Activity Questionnaire (IPAQ). OBJECTIVE: The

The ubiquitin system in normal and infected germinal center B cells

FEBS Letters, EarlyView.
The ubiquitin system plays a central role in germinal center (GC) B cells, influencing differentiation to long‐lived memory B cells. Oncogenic gammaherpesviruses gain access to memory B cells by establishing latency in GC B cells. Mapping ubiquitin mechanisms in normal and infected GC B cells will define specific molecular circuits in B cells germane ...

Metastatic niche shaped by host factors influences disseminated cancer cell fate

FEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Smaller is better: nanobodies meet NMR

FEBS Letters, EarlyView.
Nanobodies are single‐domain antigen‐binding fragments derived from camelid heavy chain antibodies. Their small size, high stability, and exceptional specificity make nanobodies uniquely useful probes for NMR studies of protein dynamics, transient conformational states, and protein–protein interactions.

Invisible but not inaccessible—Revealing transient oligomers formed by intrinsically disordered proteins with solution NMR and complementary methods

FEBS Letters, EarlyView.
Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.

Bone mineral density and accelerometer-determined habitual physical activity and inactivity in postmenopausal women [Kostní denzita a habituální pohybová aktivita a inaktivita u postmenopauzálních žen]

Acta Universitatis Palackianae Olomucensis. Gymnica, 2011
BACKGROUND: In postmenopausal women, physical activity appears to be important in preventing loss of bone mineral density (BMD) and osteoporosis and thus contributes to the reduction of fracture risk.

DNA ligase LigE increases bacterial transformation with damaged extracellular DNA

FEBS Letters, EarlyView.
The DNA ligase LigE from the naturally competent Gram‐negative bacterium Neisseria gonorrhoaea increases transformation with cut extracellular DNA. This process is ATP‐dependent and relies on the catalytic activity of LigE; it also requires that LigE contains an intact periplasmic localisation sequence, indicating that ligE functions in the periplasm ...

Going viral − Virus‐targeting nanobodies for research, diagnostics and therapy

FEBS Letters, EarlyView.
The increasing prevalence of viral diseases represents a major threat for global human health. Nanobodies, small binding fragments derived from camelid heavy‐chain antibodies, offer versatile tools for viral research, diagnostics, and antiviral therapy.
