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 ...

Microbial decolourization of textile waste water

Journal of Saudi Chemical Society, 2010
Six fungal isolates belong to Aspergillus niger, Penicillium spp., and Pleurotus osstreatus were used for decolourization activities of some acid and reactive dyes, after they screened for optimum efficiency and the condition for temperature and pH were ...

MITF maintains genome stability in nonmelanocyte lineages

Molecular Oncology, EarlyView.
MITF is essential for melanocyte survival and acts as an oncogene in 10%–20% of melanomas. We show that MITF depletion causes genome instability in nonmelanocytic cells, leading to LATS2‐mediated P53 activation, cell cycle arrest, and apoptosis. This study highlights the role of MITF as a genome maintenance factor beyond the melanocyte lineage. Created

Preoperative circulating tumor cells integrated with imaging analysis for prognostic evaluation in head and neck squamous cell carcinoma

Molecular Oncology, EarlyView.
Detecting circulating tumor cells (CTCs) in blood before surgery may help predict outcomes in patients with head and neck squamous cell carcinoma (HNSCC). Here, we show when combined with tumor size and lymph node involvement from routine imaging, CTC status identifies high‐risk patients with poorer survival—offering a simple, minimally invasive tool ...

Comparative Analysis of Anthraquinone Reactive Dyes with Direct Dyes for Papermaking Applicability

Applied Sciences
Aiming to compare the applicability and the successfulness of reactive dye printing papers’ coloration, two laboratory-synthesized anthraquinone reactive dyes are studied in comparison with two commercially available anionic and cationic direct dyes ...

Impact of high and zero formaldehyde crosslinkers on the performance of the dyed cotton fabric [PDF]

Chemical Industry and Chemical Engineering Quarterly, 2014
Performance of the colored cotton fabrics dyed with sulphur, vat, direct and reactive dyes was investigated by using two crosslinkers. DMDHEU was used as formaldehyde based crosslinker and BTCA was assessed as a zero formaldehyde alternative ...

CEACAM1 participation in breast cancer progression

Molecular Oncology, EarlyView.
In invasive breast cancer (BC), CEACAM1 shifts from an apical to a uniform membranous/cytoplasmic pattern, or is lost, as tumors dedifferentiate, inversely tracking the Ki‐67 proliferative index. In MCF‐7 cells, only CEACAM1‐4L suppresses proliferation, repressing cell cycle and growth factor genes.

Pharmacological chromatin remodeling enhances response to estrogen therapy in ER+ breast cancer

Molecular Oncology, EarlyView.
Estrogen therapy elicits clinical benefit in ~ 30% of patients with endocrine‐resistant estrogen receptor (ER)‐positive breast cancer. Based on findings that ER transcriptional activation underlies response to estrogen therapy, we tested the effects of epigenetic dysregulation via pharmacological inhibition of histone deacetylases (HDACi).

The preparation and reactivity of some photoactivable reactive dyes

Journal of Photochemistry and Photobiology A: Chemistry, 1993
Abstract A survey of the potential application of a range of carbenes as the reactive intermediates for the irreversible attachment of a dye to its substrate has been undertaken. A dye, modified with a carbene precursor, has been subjected to laser photolysis, and shown to insert with low efficiency into alcoholic solvents.
