Ovarian Cancer: Epidemiology, Disease Mechanisms, New Diagnosis and Treatment Strategies, and Research Directions

open access: yesiNew Medicine, EarlyView.
ABSTRACT Ovarian cancer (OC) continues to be the deadliest gynecological malignancy and a significant cause of cancer‐related mortality among women worldwide. Standard treatment strategies typically entail platinum‐based chemotherapy in conjunction with cytoreductive surgery.

Assessment of Glucose Metabolism in Vivo in the Human Frontal Lobe Using Interleaved 1H and 13C MRS at 7T

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background 13C magnetic resonance spectroscopy (MRS), combined with 13C‐labeled substrate infusion, offers a nonionizing, minimally invasive method for assessing fluxes through the main cerebral energy metabolism pathways. However, its human application at 7T has not been fully established, especially within the frontal lobe, where alterations

Stable isotope analysis of freshwater gastropod carbonates from Swanscombe: Insights into climate stability and seasonality during MIS 11c

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Stable isotope analyses of freshwater mollusc carbonate can record environmental conditions at the time of mineralisation, yet this technique remains underused in British Middle Pleistocene fluvial sequences, despite the abundance of fossil shell material in these deposits.

Ngarrawa (mound spring) sediments as archives of Holocene environmental change in arid central Australia: Insights from Itrax XRF scanning

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Central Australia's ngarrawa, or ‘mound springs’, are unique hydrological systems that serve as some of the only near‐permanent sources of water and continuous sediment deposition in Australia's arid interior. As such, they hold significant potential as palaeo‐climate and ‐environmental archives in a region where many aspects of past climate ...

Qualitative Analysis of Biogas by Raman Spectroscopy: Effect of Pressure on Major Components

open access: yesJournal of Raman Spectroscopy, EarlyView.
Raman spectra of major and selected minor biogas components were studied under pressures up to 100 bar. Pressure‐induced shifts and band broadening were quantified for methane, carbon dioxide, and nitrogen, while Raman spectra of ammonia and hydrogen sulfide are presented in the context of biogas quality monitoring.

Detection of Acoustic Phonons in Carbon by Raman Spectroscopy

open access: yesJournal of Raman Spectroscopy, EarlyView.
Acoustic phonons in graphite and diamond are detected by Raman spectroscopy through disorder‐induced relaxation of selection rules. Comparison with calculated phonon densities of states enables assignment of the observed Raman features to acoustic phonon branches.

Preparation and Certification of Reference Materials for Hydrogen and Oxygen Isotopes in Water

open access: yesYankuang ceshi, 2013
Certified reference materials of water for stable hydrogen and oxygen isotopes were developed and have been used for more than 30 years. However, they no longer meet the requirements for newly developed technologies. New reference materials of water have

Spin-isospin transitions in chromium isotopes within the quasiparticle random phase approximation

open access: yes
Beta decay and electron capture on isotopes of chromium are advocated to play a key role in the stellar evolution process. In this paper we endeavor to study charge-changing transitions for 24 isotopes of chromium (Cr42-65).
