Ink4a/Arf−/− and HRAS(G12V) transform mouse mammary cells into triple-negative breast cancer containing tumorigenic CD49f− quiescent cells
Intratumoral heterogeneity within individual breast tumors is a well-known phenomenon that may contribute to drug resistance. This heterogeneity is dependent on several factors, such as types of oncogenic driv...

Open AccessStatin use in primary inflammatory breast cancer: a cohort study
Some studies have suggested that statins, which have cholesterol-lowering and anti-inflammatory properties, may have antitumor effects. Effects of statins on inflammatory breast cancer (IBC) have never been st...

Ink4a and Arf are crucial factors in the determination of the cell of origin and the therapeutic sensitivity of Myc-induced mouse lymphoid tumor
The cell of origin of tumors and the factors determining the cell of origin remain unclear. In this study, a mouse model of precursor B acute lymphoblastic leukemia/lymphoma (pre-B ALL/LBL) was established by ...

The Hard X-ray Telescope (HXT) for the SOLAR-A mission
The Hard X-ray Telescope (HXT) is a Fourier-synthesis imager; a set of spatially-modulated photon count data are taken from 64 independent subcollimators and are Fourier-transformed into an image by using proc...

Microwave Observations of the Sun During the 22nd Solar Activity Cycle — 17 GHz Radio Heliograph
For the study of high energy phenomena on the Sun during the maximum period of the 22-nd solar activity cycle, we started to construct a radio heliograph at Nobeyama Radio Observatory. The operating frequency ...

Cytotoxic effects of a leukocidin from Fusobacterium necrophorum on bovine hepatic cells
Cytotoxic effects of a leukocidin from Fusobacterium necrophorum were demonstrated on bovine hepatic cells. The cytotoxic response was dose-dependent and could be inhibited by homologous antiserum. Scanning elect...

Radio evidence for a delayed acceleration process in solar flares
Evidence for a delayed acceleration process in solar flares is presented in the form of an analysis of simultaneous observations in microwaves, decimetre and metrewaves, and hard X-rays of six ‘delayed’ gradua...

X-ray imaging of a solar limb flare on 1982 January 22
Simultaneous X-ray images in hard (20–40 keV) and softer (6.5–15 keV) energy ranges were obtained with the hard X-ray telescope aboard the Hinotori spacecraft of an impulsive solar X-ray burst associated with ...

Can observed hard X-ray and microwave flux from solar flares be explained by a single electron population?
In attempting to explain observed hard X-ray and microwave flux from solar flares by a single population of energetic electrons, one has met a serious discrepancy of the order of 103–105 between the calculated an...

Successive electron and ion accelerations in impulsive solar flares on 7 and 21 June 1980
A study of the relative timing of solar flare emissions at different wavelengths can provide valuable insights into the associated particle-acceleration mechanisms. We report here that the significant systemat...

Late phase gradual enhancements in microwaves and hard X-rays of the 6 November 1980 flare
Gradual enhancements which repeatedly appeared 20–50 min after the onset of an impulsive burst were observed in microwaves and hard X-rays. The observed characteristics of the gradual enhancements are (i) the ...

Source structure of gradual rise and fall bursts at 17 GHz
From ∼ 200 GRF (gradual rise and fall) bursts which have been recorded with the 17 GHz interferometer at Nobeyama, we deduce the following characteristics of GRF bursts: (1) Sources of GRF bursts are broader, ...

Unusual Absorption of a Solar Type II Burst by ‘Shadow’ Type III Bursts
The Hα-flare on 1968 August 23d23h45m was followed by a short-lived type II burst. The radio spectrograph record obtained at Culgoora is shown in Figure 1. The type II burst was of split-band structure with unusu...

The structure, polarization, and spatial relationship of solar radio sources of spectral types I and III
A description is given of recent high-resolution observations of the sun made at 80 MHz with the Culgoora radioheliograph. In many cases the sources of type I storms show bi-polar structure, the two components...
