Operation of a free-electron laser from the extreme ultraviolet to the water window [PDF]

open access: yes, 2007
We report results on the performance of a free-electron laser operating at a wavelength of 13.7 nm where unprecedented peak and average powers for a coherent extreme-ultraviolet radiation source have been measured.

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes

open access: yesFEBS Letters, EarlyView.
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics

The Impact of Lighting Treatments on the Biosynthesis of Phenolic Acids in Black Wheat Seedlings

open access: yesFoods
Light, as a crucial environmental determinant, profoundly influences the synthesis of secondary metabolites in plant metabolism. This study investigated the impacts of the red light combined with ultraviolet-A (UV-A) and ultraviolet-B (UV-B) treatments ...

Ultraviolet radiation suppresses obesity and symptoms of metabolic syndrome independently of vitamin d in mice fed a high-fat diet [PDF]

open access: yes, 2014
The role of vitamin D in curtailing the development of obesity and comorbidities such as the metabolic syndrome (MetS) and type 2 diabetes has received much attention recently. However, clinical trials have failed to conclusively demonstrate the benefits

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

open access: yesMolecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

Laser-stimulated fluorescence reveals unseen details in fossils from the Upper Jurassic Solnhofen Limestones

open access: yesRoyal Society Open Science, 2021
Laser-stimulated fluorescence (LSF) has seen increased use in palaeontological investigations in recent years. The method uses the high flux of laser light of visible wavelengths to reveal details sometimes missed by traditional long-wave ultraviolet (UV)

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

CONSIDERATIONS CONCERNING THE INFLUENCE OF UV RADIATIONS ON THE BODY [PDF]

open access: yesAnalele Universităţii "Constantin Brâncuşi" din Târgu Jiu: Seria Inginerie, 2019
This paper shows how the association between ultraviolet light (UV) and the diseases produced by the human body. There is strong evidence that exposure to ultraviolet radiation (UVR) is associated with malignancy of basal cell carcinoma, photokeratitis ...

Ultraviolet: a regulator of immunity [PDF]

open access: yes, 2008
紫外線は免疫を制御する因子の一つである.紫外線照射により腫瘍免疫が抑制される事,SLEや皮膚筋炎などの自己免疫疾患が増悪する事,ヘルペスウイルスなどによる感染症が増悪する事などがよく知られている.さらに紫外線は,尋常性乾癬や尋常性白斑などの炎症性皮膚疾患の治療にも広く臨床応用されている.紫外線による免疫抑制機序は複雑で,未だ一定の見解を得られていない.リンパ組織を移入する事で,紫外線により生じた抗原特異的な免疫寛容が他のマウスに転嫁できるという所見より ...
