Salāmat-i kār-i Īrān, 2009 Background and aimsRespirators are widely employed as the only measure against respiratory hazards. However, it is well known that unless workers wear respiratory continuouslyand properly, its efficacy will be very low.

Numerical simulation on protective performance for the O2 generator of a chemical oxygen respirator
工程科学学报, 2015 A 2D axisymmetric mathematical model was developed for an O2 generator and the protective performance of the O2 generator was simulated. The model's rationality was verified by experiments under typical operational conditions.

Surgical masks vs respirators for the protection against coronavirus infection: state of the art
, 2020 Background: During the Covid-19 outbreak, a recurrent subject in scientific literature has been brought back into discussion: whether surgical masks provide a sufficient protection against airborne SARS-CoV-2 infections.

Tumour‐proximal deep serum proteomics identifies biomarkers associated with ovarian cancer
Molecular Oncology, EarlyView.New biomarkers are needed for early ovarian cancer detection. Ovarian (tumour‐proximal) and peripheral vein serum from healthy women and patients with benign or malignant tumours underwent nanoparticle‐enriched deep proteomics. Ovarian serum yielded more protein identifications and revealed tumour‐reflective signatures.

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes
FEBS Open Bio, EarlyView.Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

What are atmosphere-supplying respirators? [PDF]
Atmosphere-supplying respirators provide clean breathing air from a source separate from the work area. These respirators protect wearers from many types of contaminants (particles, gases, and vapors).

FEBS Open Bio, EarlyView.The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Ionomycin suppresses cancer cell growth by disrupting mitochondrial transcription
FEBS Open Bio, EarlyView.In this study, we identify a new function for the selective Ca2+ ionophore, ionomycin, as an inhibitor of mitochondrial transcription. Both total and nascent RNA analyses revealed that ionomycin treatment reduces the transcription of mitochondrial genes.
