here since it was founded in that city in 1950. This 15th volume of the Advances in Neurosurgery contains the papers read there on the chief topics. The first main topic covered is one of the basic aspects of our neuro surgical activity - the regulation of cerebral circulation and brain metabolismLINES 发表于 2025-3-27 04:02:58
Werner Kirsch,Kai Obringansduction, one of the most extensively characterized regulatory photoreceptors, phytochrome. This binary molecule switches “on” and “off” plant gene expression in response to light (1). Phytochrome controls in a positive or negative way the expression of numerous genes, including its own (2–4). Phy天气 发表于 2025-3-27 06:53:30

Plastocyanin is confined to chloroplast-containing tissues, and is not found in roots (Katoh et al., 1961; de Boer et al., 1988; Last and Gray, 1990). Similarly, plastocyanin mRNA is found only in photosynthetic tissues or tissues destined to become phot一加就喷出 发表于 2025-3-27 12:41:04

Frank Wimmer,Georg Rothy charge. We have used isolated guinea pig and rat hearts to test this hypothesis measuring in vivo high energy phosphate concentrations with .P-NMR. Several different interventions were used to lower energy charge (and phosphorylation potential), including norepinephrine (NE) infusion, hypoperfusio赞美者 发表于 2025-3-27 22:08:37

Erwin Dichtl,Annick Dohetuse of its excellent accessibility to coronary vessels of the beating heart. We designed four different accesses of a fiber probe to measure blood velocities, depending upon the objectives of the measurements, i. e., epicardial large coronary vessels, the epicardial small artery and vein, the intram单色 发表于 2025-3-28 13:58:01
Heinz Rehkuglere, we have developed a new microscopic system which we termed the “floating objective system”, and which consists of a pair of convex lenses vertically aligned on the same optical axis. The real image on the front focus of a lens facing the heart (floating lens) is transmitted to the back focus of a
