The evaluation of Corona and Ikonos satellite imagery for archaeological applications in a semi-arid environment [PDF]

open access: yes, 2004
Archaeologists have been aware of the potential of satellite imagery as a tool almost since the first Earth remote sensing satellite. Initially sensors such as Landsat had a ground resolution which was too coarse for thorough archaeological prospection ...

Lipid Profile in Primary Aldosteronism: Cross‐Sectional and Post‐Treatment Analyses

open access: yesLipids, EarlyView.
ABSTRACT The relationship between primary aldosteronism (PA) and lipid metabolism remains controversial, with inconsistent findings reported in the literature. This study aimed to clarify PA's impact on the lipid profile using both a cross‐sectional comparison with essential hypertension (EH) controls and a longitudinal within‐patient pre‐post ...

Recent Advances (2023–2025) of Capillary Electrophoresis‐Mass Spectrometry (CE‐MS) for Top‐Down Proteomics

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Top‐down proteomics (TDP) characterizes proteoforms in cells, tissues, and biofluids, in discovery mode and on a global scale, requiring analytical tools with high peak capacity for proteoform separation and high sensitivity for proteoform detection, given the extremely high proteoform complexity and wide proteoform concentration dynamic range.

Destruction of Sun-Grazing Comet C-2011 N3 (SOHO) Within the Low Solar Corona

open access: yes, 2012
Observations of comets in Sun-grazing orbits that survive solar insolation long enough to penetrate into the Suns inner corona provide information on the solar atmosphere and magnetic field as well as on the makeup of the comet. On 6 July 2011, the Solar

Harnessing Natural Compounds in Psoriasis: Targeting Cellular Pathways for Effective Therapy

open access: yesPhytotherapy Research, EarlyView.
Natural compounds act on key cellular pathways in psoriasis by suppressing keratinocyte hyperproliferation, modulating Th17/IL‐17‐mediated immune responses, and reducing oxidative stress. These multi‐target effects highlight their potential as safer adjunctive therapies alongside conventional treatments.
