Technical note: a new technique for interpolating the reflectance red edge position

open access: yes, 1998
. The point of maximum slope on the re¯ectance spectrum of vegetation between red and near-infrared wavelengths, termed the red edge position (REP), is correlated strongly with foliar chlorophyll content and provides a very sensitive indicator of, among ...

Grass Chlorophyll and the Reflectance Red Edge

open access: yes, 1996
The point of maximum slope in the reflectance spectra of leaves occurs around 690-740nm and is termed the 'red edge'. Strong correlations have been found between the red edge of leaves and the chlorophyll concentration of those leaves.

PAK1 activation drives divergent resistance mechanisms to aromatase inhibition and tamoxifen in a luminal: A breast cancer model

open access: yesMolecular Oncology, EarlyView.
Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.

Spatial and single‐nuclei transcriptomics reveals idiosyncratic and generic patterns in papillary and anaplastic thyroid cancers

open access: yesMolecular Oncology, EarlyView.
Matched spatial transcriptomics and single‐nuclei RNA‐seq were generated for anaplastic and BRAFV600E papillary thyroid cancers revealing generic and tumor‐specific states occurring in cancer cells and in the tumor microenvironment. In this context, cancer dedifferentiation mirrored organoid maturation through ordered thyroid marker gain/loss ...

CEACAM1 participation in breast cancer progression

open access: yesMolecular 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.

Analysis of spectral signatures and vegetation indices to assess the response of faba bean plants to varying zinc levels under sandy soil conditions

open access: yesFrontiers in Environmental Science
IntroductionZinc (Zn) deficiency is a major limiting factor for crop productivity, particularly in sandy soils where nutrient retention and bioavailability are poor.

Oral History Interview with Jack Edge

open access: yes
The National Museum of the Pacific War presents a monologue with Jack Edge. Edge joined the Navy in 1941. He served aboard the USS Pelias (AS-14). They were conducting submarine overhauls at the Submarine Base where the ship was berthed during the ...

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

open access: yesMolecular 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).

PANoptosis in the pathogenesis of myelodysplastic syndromes

open access: yesMolecular Oncology, EarlyView.
PANoptosis, a combination of three types of programmed cell death, is mediated by a large protein complex called a PANoptosome. In healthy bone marrow hematopoietic cells, PANoptosis is restricted by inhibitory signaling. In MDS, bone marrow cells become sensitive to the PANoptotic stimuli due to the aberrant inactivation of inhibitory signaling or ...

Probing the exotic emission behaviors of Gd3+ ions in Gd3Ga5O12 wafer via X-ray excited optical luminescence

open access: yesResults in Optics
We investigate the exotic emission behaviors of gadolinium gallium garnet (Gd3Ga5O12, GGG) wafer via X-ray absorption near edge structure (XANES) and X-ray excited optical luminescence (XEOL) in an X-ray nanoprobe beamline. The XANES spectra of the Gd L3
