Temperature-controlled alternative respiration and outgrowth rate from conidia ofNeurospora crassa

Summary Incubation of conidia of wild typeNeurospora crassa at temperatures ranging from 25 to 46°C modulates their respiratory type. Between 37 and 41°C, the transient activity of the cyanide-insensitive respiratory pathway parallels, with a maximal extrusion of protons into the medium, the optimal rate of germ tube outgrowth.We are grateful to Mrs Arlette Cattaneo for her competent technical assistance.     

Retroviruses released from a human tumor xenograft in nude mice induce colony-stimulating factor (CSF) activity in human fibroblastic cells

Summary A human colony-stimulating factor (CSF)-producing tumor transplanted into athymic nude mice released retroviruses in vitro. The viruses induced CSF activity in human fibroblastic cell lines.     

Light and temperature affect retinyl ester hydrolase activity and visual pigment composition

Summary Dim light, in combination with high water temperature, resulted in a significant increase in the retinyl ester hydrolase activity in the goldfish retina. This rise in enzyme activity may relate to a selective increase in the availability of retinal chromophores thereby favoring the formation of rhodopsin under these light and temperature conditions.     

铁磁膜的居里温度

在考虑了边界条件对电子态和电子组态的影响乃至对自旋之间交换作用影响的基础上，计算了４￣７单分子层厚的铁磁膜的居里温度随膜厚的变化关系。结果表明居里温度随膜变薄而降低，这从微观上肯定了一般的理论预测并解释了近期的实验结果。     

Cytosolic factors in mitochondrial protein import

In vitro import studies have confirmed the participation of cytosolic protein factors in the import of various precursor proteins into mitochondria. The requirement for extramitochondrial adenosine triphosphate for the import of a group of precursor proteins seems to be correlated with the chaperone activity of the cytosolic protein factors. One of the cytosolic protein factors is hsp70, which generally recognizes and binds unfolded proteins in the cytoplasm. Hsp70 keeps the newly synthesized mitochondrial precursor proteins in import-competent unfolded conformations. Another cytosolic protein factor that has been characterized is mitochondrial import stimulation factor (MSF), which seems to be specific to mitochondrial precursor proteins. MSF recognizes the mitochondrial precursor proteins, forms a complex with them and targets them to the receptors on the outer surface of mitochondria.
