A Scanning Electron Microscope for Ultracold Atoms

open access: yes, 2006
We propose a new technique for the detection of single atoms in ultracold quantum gases. The technique is based on scanning electron microscopy and employs the electron impact ionization of trapped atoms with a focussed electron probe.

Consequences of anisotropy in electrical charge storage: application to the characterization by the mirror method of TiO2 rutile [PDF]

open access: yes, 2008
This article is devoted first to anisotropic distributions of stored electric charges in isotropic materials, second to charge trapping and induced electrostatic potential in anisotropic dielectrics.

A case of trichorrhexis nodosa

open access: yesPifu-xingbing zhenliaoxue zazhi, 2022
We report a case of trichorrhexis nodosa. A 27-year-old female presented with white nodules of hair that were easily broken for 17 years. Dermatological examination showed that the hair was sparse, dry, and there were many tiny granular white nodules ...

PARP inhibition and pharmacological ascorbate demonstrate synergy in castration‐resistant prostate cancer

open access: yesMolecular Oncology, EarlyView.
Pharmacologic ascorbate (vitamin C) increases ROS, disrupts cellular metabolism, and induces DNA damage in CRPC cells. These effects sensitize tumors to PARP inhibition, producing synergistic growth suppression with olaparib in vitro and significantly delayed tumor progression in vivo. Pyruvate rescue confirms ROS‐dependent activity.

Pioglitazone plus (−)‐epigallocatechin gallate: a novel approach to enhance osteogenic performance in aged bone marrow mesenchymal stem cells

open access: yesFEBS Open Bio, EarlyView.
Aged human bmMSCs are seeded in the scaffold. Osteoblastic induction can slightly increase cell's bone‐forming activity to produce bone‐like tissues, shown as the sporadic xylenol orange‐stained spots (the lower left image). Notably, pioglitazone plus EGCG co‐treatment dramatically increases cell's bone‐forming activity and bone‐like tissue production (

Dapagliflozin prevents methylglyoxal‐induced retinal cell death in ARPE‐19 cells

open access: yesFEBS Open Bio, EarlyView.
Diabetic macular oedema is a diabetes complication of the eye, which may lead to permanent blindness. ARPE‐19 are human retinal cells used to study retinal diseases and potential therapeutics. Methylglyoxal is a compound increased in uncontrolled diabetes due to elevated blood glucose.

Examination of mycological samples by means of the scanning electron microscope

open access: yesRevista da Sociedade Brasileira de Medicina Tropical, 1973
Three species of Siphomycetes: Rhizopus arhizus, Rhizopus equinus and Rhizopus nigricans, as well as a Septomycete: Emericella nidulans, have been examined by means of a scanning electron microscope.

Imaging of native early embryogenic tissue of Scots pine (Pinus sylvestris L.) by ESEM

open access: yesOpen Life Sciences, 2015
Environmental scanning electron microscopy enables the investigation of uncoated pine early embryogenic tissue samples in situ. The samples were examined under low vacuum conditions (air pressure 550 Pa) at a temperature of around -18°C by the AQUASEM II
