Neodymium‐Doped Nanocrystals for Sensing Cellular Temperature at the Nanoscale

open access: yesAdvanced Optical Materials, EarlyView.
Neodymium‐doped NaYF4 nanocrystals are engineered as bright, biocompatible nanothermometers for intracellular temperature mapping. Their ratiometric near‐infrared emission enables highly sensitive, nanoscale thermal readouts in living cells. Combined with gold nanostars for photothermal therapy, they reveal pronounced subcellular heating heterogeneity ...

Ethidium bromide binding to polyriboguanylic acid

open access: yes, 1989
Исследовано связывание бромистого этидия (БЭ) с полирибогуаниловой кислотой по характеру изменения спектров поглощения. Расчеты показали, что стехиометрия насыщения составляет одну молекулу БЭ на пять гуанинов с константой связывания (5,2±0,8) -10⁴M⁻¹ ...

Placental Site Trophoblastic Tumor Acquires Immune Functions by Incorporating Host Maternal Genes

open access: yesAdvanced Science, EarlyView.
PSTT cells, through cell fusion with B cells, incorporate abundant non‐inherited maternal genes that are detectable by DNIMA. These hybrid cells acquire immunotherapy‐resistant genetic changes and increase the expression of B cell‐derived immune‐related molecules such as Ig, HLA, LILRB, SIGLEC10, and so on, creating an immunotolerant environment around

EPMs block efflux of ethidium bromide and Nile red.

open access: yes, 2018
Salmonella were incubated with either ethidium bromide or Nile red without glucose, treated with compound, exposed to glucose, and then monitored for fluorescence. Data for each sample were normalized to the initial fluorescence (100%).

Inhibition of KDEL Receptors Remodels the Tumor Microenvironment for T Cell Independent Tumor Regression

open access: yesAdvanced Science, EarlyView.
Inhibition of KDELR2 in a small fraction of tumor cells generates sustainable immunogenic cell death conditions within the tumor microenvironment. These conditions promote the regression of tumors in a T cell independent manner. During regression, macrophages prime T cells that subsequently provide systemic protection against recurrence. The potency of

HEAVY METAL RESISTANCE AND ANTIBIOTIC RESISTANCE IN HOSPITAL ISOLATES OF STAPHYLOCOCCUS AUREUS FROM KARACHI

open access: yesFUUAST Journal of Biology, 2021
One hundred and five hospital strains of Staphylococcus aureus isolated from in-patients and out-patients were examined for sensitivity to heavy-metal ions i.e. cadmium and mercury.

The binding of polyamines and of ethidium bromide to tRNA

open access: yesNucleic Acids Research, 1975
The binding of spermidine and ethidium bromide to mixed tRNA and phenylalanine tRNA has been studied under equilibrium conditions. The numbers and classes of binding sites obtained have been compared to those found in complexes isolated by gel filtration a low ionic strength. The latter complexes contain 10-11 moles of either spermidine or ethidium per

Human Urine Stem Cells Alleviate Pulmonary Fibrosis via Inhibiting Macrophage‐Myofibroblast Transition

open access: yesAdvanced Science, EarlyView.
Therapeutic role and mechanism of human urine stem cells (hUSCs) in pulmonary fibrosis. hUSCs alleviated pulmonary fibrosis by selectively inhibiting macrophage‐myofibroblast transition (MMT) in two ways: on one hand, hUSCs inhibited mitochondrial reactive oxygen species (mtROS) production and apoptosis/senescence of epithelial cells in pulmonary ...

Impact of DNA damaging agents on genome-wide transcriptional profiles in two marine Synechococcus species

open access: yesFrontiers in Microbiology, 2013
Marine microorganisms, particularly those residing in coastal areas, may come in contact with any number of chemicals of environmental or xenobiotic origin.
