Measurement of Ultra-High Energy Cosmic Rays with CHICOS [PDF]

open access: yes, 2009
The California HIgh school Cosmic ray ObServatory (CHICOS) is a ground-based scintillator array designed to measure the extended air showers of ultra-high energy cosmic rays. The goal of the project is to gain insight into the origin of ultra-high energy

Potensi Ekstrak Bawang Hitam sebagai Tabir Surya terhadap Paparan Sinar Ultraviolet

open access: yesKeluwih, 2020
—Skin cancer is in the third rank in Indonesia. One of the causes of skin cancer is excessive exposure to ultraviolet rays from the sun. Ultraviolet radiation forms Reactive Oxygen Species that disrupts the regulation of the cell-matrix and causes ...

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

open access: yesMolecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Regulation of the lncRNA NEAT1 by p53‐ΔNp63 crosstalk modulates the DNA damage response and therapeutic efficacy in HNSCC

open access: yesMolecular Oncology, EarlyView.
In head and neck squamous cell carcinoma (HNSCC) p53 and p63 exert opposite roles on the transcription regulation of the lncRNA NEAT1. Under basal conditions, p53 levels are low and p63 represses NEAT1 expression. Upon genotoxic stress, p53 is rapidly induced, displacing p63 from the NEAT1 promoter leading to NEAT1 transcriptional activation and ...

On the Ultraviolet Rays.

open access: yesJOURNAL OF THE ILLUMINATING ENGINEERING INSTITUTE OF JAPAN, 1928
此の講演は自分の研究の結果を發表したのではなく, 今日まで多くの人々によつて研究された事柄を目次に示すやうに分類し, 紫外線の呈する多くの作用を述べ, それが實際上如何なる方面に應用されて居るかを解説したものである。日光は保健上有効であると云ふことは二千年の昔から知られて居たが, それは學術的に根据はなかつた。日光の中に紫外線のあることは十九世紀の始めに發見された。それから漸次日光の中の紫外線が人體に有効であると云ふことが知られ, 紫外線の分量の多い高山に療養所が出來るやうになつた。而して今日では尚張い紫外線を出す人工的の光源を病症治癒のために用ひるやうになつた。既は紫外線の有する殺菌作用及生理的亢進作用に依るのである。又紫外線の有する螢光作用及燐光作用は寳石, 手形 ...

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.

SPHINX31 acts as a SRPK1 inhibitor targeting the ATR/DNA‐PKcs/CHK1 replicative checkpoint to inhibit cell growth in non‐small cell lung cancer

open access: yesMolecular Oncology, EarlyView.
The kinase SRPK1 directly interacts with the protein TOPBP1 and regulates the pre‐mRNA splicing of WIZ thereby contributing to the activation of the ATR/CHK1 replicative checkpoint in response to replicative stress. This allows cancer cells' genomic stability and survival.
