Nanowires In article number 2200656, Donglei Emma Fan, Yuebing Zheng, and co-workers achieve strong coupling between excitons Mie resonances in chemically synthesized transition metal dichalcogenide nanowires. The coupling-induced optical responses are further modulated a reversible way, enabling new class of tunable photonic devices.
The purpose of this communication is to bring up to date an experimental study of 55 chemically induced fowl sarcomas, first described some 12 years ago (16-18), and to compare these results with others obtained in parallel experiments with 3 infective fowl sarcomas transmissible by cell-free material. The bearand from further discussion, because they retrogressed during the first serial passag...
In this letter, we report the first observation of surface plasmon-coupled chemiluminescence (SPCC), where the luminescence from chemically induced electronic excited states couples to surface plasmons in a thin continuous silver film. The SPCC is highly directional and predominantly p-polarized, strongly suggesting that the emission is from surface plasmons instead of the luminophores directly...
We have previously reported that two chemically induced sarcomas of BALB/c mice (MCA-1315 and -1321) contained common transplantation antigens which could be detected by immunization of normal BALB/c mice with irradiated tumor cells of each line. This cross-protection could not be detected in animals surgically cured of these tumor lines and challenged with a high dose of tumor cells, but it wa...
Activation of the stress-activated mitogen-activated protein kinases (MAP kinases), c-Jun N-terminal kinase (JNK) and p38, is necessary for the induction of apoptosis in neuronal cells; however, in other cell types their involvement may be stimulus-dependent. In the present study we investigate the activation of JNK and p38 in a single non-neuronal cell type, undergoing receptor-mediated (tumou...
Electron microscopy of butylated hydroxytoluene-induced lung damage. HP Lung injury induced by butylated hydroxytoluene: cytodynamic and biochemical studies in mice. Potentiation of diffuse lung damage by oxygen: determining variables. of butylated hydroxytoluene-induced acute lung damage by oxygen: cell kinetics and collagen metabolism. of chemically induced lung fibrosis by thorax irradiation.
Spontaneous mammary tumour incidence, at death, of intact C3H(Jax) virgin female mice was not altered by treatment with testosterone propionate, given upto the beginning of tumour age. In 6 out of 12 mice, testosterone delayed the appearance of tumours and thus added to their longevity significantly. The type of mammary tumours obtained in testosterone-treated female mice was largely similar to...
