Chemical Absorption and Mass Transfer of Greenhouse Gas Carbon Dioxide

Chemical Engineering Transactions, 2018
The findings regarding CO2 emissions and efficient absorption of CO2 have important implications for controlling the greenhouse effect. This paper describes the preparation of a mixture with mono ethanol amine (MEA) and N-methyldiethanolamine (MDEA) for ...

The role of tachysterol in vitamin D photosynthesis - A non-adiabatic molecular dynamics study

, 2017
To investigate the role of tachysterol in the photophysical/chemical regulation of vitamin D photosynthesis, we studied its electronic absorption properties and excited state dynamics using time-dependent density functional theory (TDDFT), coupled ...

Deciphering transcriptional plasticity in pancreatic ductal adenocarcinoma reveals alterations in sensory neuron innervation

Molecular Oncology, EarlyView.
Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.

CCDC80 suppresses high‐grade serous ovarian cancer migration via negative regulation of B7‐H3

Molecular Oncology, EarlyView.
PAX8 is a lineage‐specific master regulator of transcription in high‐grade serous ovarian cancer (HGSC) progression. We show for the first time that PAX8 facilitates proliferation and metastasis by repressing the cell autonomous tumor suppressor CCDC80 and inducing B7‐H3 expression.

AVALIAÇÃO ESPECTROFOTOMÉTRICA DAS FORMAS CR+3, CRO4 -2 E CR2O7 -2

Eclética Química, 2018
A spectrophometric study of the speciation of the chemical forms Cr+3, CrO4-2 and Cr2O7-2 was carried out on a wide interval of pH (from 2,0 to 12,0) in a Britton-Robinson buffer solution. The absorption spectra of the ultraviolet and visible regions are

CD47 promotes mitogen‐activated protein kinase and epithelial‐to‐mesenchymal transition molecular programs to drive prometastatic phenotypes in non‐small cell lung cancer

Molecular Oncology, EarlyView.
Beyond its role in immune evasion, this study identified that CD47 drives tumor‐intrinsic signaling in non‐small cell lung cancer (NSCLC). Transcriptomic profiling and functional studies revealed that CD47 regulates cell adhesion, migration, and metastasis through an ERK–EMT signaling axis.

Determination of absorption dose in chemical mutagenesis in plants.

PLoS ONE, 2019
Chemical mutagenesis is a useful tool for inducing mutations in plants. Seeds are often used as the material for chemical mutagenesis. The biological effect of a chemical mutagen on seeds is determined by absorption dose (the product of mutagen ...

Adaptor protein CIN85 potentiates the motility of osteosarcoma cells via the Akt/mTOR and MMP2‐COL3A1 axis

Molecular Oncology, EarlyView.
CIN85 is highly expressed in osteosarcoma, particularly in metastatic lesions. Its overexpression increases cell migration and Matrigel invasion, while silencing CIN85 suppresses these behaviors. Transcriptome analysis shows that CIN85 regulates MMP2, COL3A1, and Akt/mTOR signaling. Targeting these pathways reverses CIN85‐induced motility, highlighting

Two-Photon Absorption in Gapped Bilayer Graphene with a Tunable Chemical Potential

, 2016
Despite the now vast body of two-dimensional materials under study, bilayer graphene remains unique in two ways: it hosts a simultaneously tunable band gap and electron density; and stems from simple fabrication methods.
