A new flow chip in combination with multiphoton microscopy as a protocol for longitudinal 3D imaging of tissue calcification under shear stress

open access: yesFEBS Open Bio, EarlyView.
Miniaturized flow chip platform enabling continuous perfusion and longitudinal multiphoton 3D imaging of vascular smooth muscle cell constructs under physiological flow. Brightfield imaging guides region selection, while CellTracker Green and mRuby‐labeled fetuin‐A visualize cells and mineral deposition, respectively. Magnesium supplementation markedly

A Newer In Vitro Model for the Study of Development of in vitro resistance to penicillin in a novel isolate of Streptococcus tigurinus

open access: yesJournal of Microbiology and Infectious Diseases, 2017
Objectives: Streptococcus tigurinus is a new member of the Streptococcus mitis group. It causes various invasive infections. Its isolation from the oral cavity has been reported recently for the first time in our previous study.

Protocol for quantifying miRNA trafficking across the endosomal membrane

open access: yesFEBS Open Bio, EarlyView.
An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.

Antibiotic resistance of Staphylococcus aureus associated with subclinical and clinical mastitis in Uruguay during an eight-year period

open access: yesAustral Journal of Veterinary Sciences, 2017
Records of in vitro susceptibility tests performed between 2008 and 2015 were retrospectively reviewed in order to evaluate the dynamic profiles of possible changes in antimicrobial resistance of Staphylococcus aureus isolated from milk samples of cows ...

Streptococcus pneumoniae penicillin resistance in Turkey

open access: yes, 2001
Resistance of Streptococcus pneumoniae (750) to penicillin, erythromycin, chloramphenicol and trimethoprim/sulfamethoxazole isolated in 4 Turkish hospitals between 1996 and 1999 was evaluated according to year of isolation, patients' age groups and ...

Dual native G‐quadruplex folding is associated with chromatin looping at the MYC locus

open access: yesFEBS Open Bio, EarlyView.
BG4‐detectable G‐quadruplex (G4) in HaCaT and NHEK keratinocytes identified folded and unfolded G4s enriched at promoters/TSSs and active enhancers, whereas unfolded G4s also overlapped weak/poised enhancers. At MYC–PVT1, 3C‐qPCR detected enhancer–promoter looping only when G4s were simultaneously folded at both regulatory elements under native ...

Characterisation of pneumococcal peptidoglycan cross-linking enzymology [PDF]

open access: yes
Despite the introduction of penicillin, infections caused by Streptococcus pneumoniae are associated with significant morbidity and mortality. As a result, there is an urgent need for successful identification of new drug targets within the organism ...

A study of clinical strains of Pseudomonas Aeruginosa and the investigation of antibiotic resistance mechanisms in the multidrug resistant strain PA13 [PDF]

open access: yes, 2008
Thirteen clinical strains of bacteria from two Irish hospitals were identified as Pseudomonas aeruginosa using classical methods, API 20NE and Biolog GN. Their identification was confirmed by 16S rRNA gene sequencing.

Transfer of penicillin resistance between Neisseriae in microcosm [PDF]

open access: yes, 2014
Horizontal gene transfer between commensal and pathogenic Neisseriae is the mechanism proposed to explain how pathogenic species acquire altered portions of the penA gene, which encodes penicillin binding protein 2. These changes resulted in a moderately
