伴侣犬我们身边的朋友

沙皮犬(Shar-Pei)世界上最稀少的犬,原产我国广东。至今已有2000多年历史。因为皮肤宽松多褶、毛短而硬、酷似沙皮而得名。被毛短密、粗硬、颜色有浅黄、宗黄和米色、黑色等。体高46～51厘米。体重18～25千克。头硕大呈方形,嘴部宽长,舌头为特殊的紫蓝色,耳朵小并且向前下垂,眼睛深邃,凹藏于眼窝内。脖颈短而粗壮。躯干呈圆筒状。四肢结识,尾巴上扬。全身肌肉发达。沙皮犬从外表看似沉郁、凝重,但性格顽皮,忠实可爱。它们是原始的、充满热情的犬。在生人面前它们显得拘谨、警惕,随时做好防御的准备,但它们决不会主动发动攻击。它们还是一种讲卫生的家庭宠物犬。     

世界各国生物工艺学研究概况

五年来,在美国先后出现了一百五十个从事生物工艺学研制的公司。这些公司生意兴隆、财政富裕。在欧洲各国成立的生物工艺学公司也是如此。毫无疑问,生物工艺学具有美好的前景。财政界已开始认识到发展生物工艺学工业的重要意义。     

杨钟健与刘东生的师生情谊——纪念杨钟健院士逝世30周年

杨钟健院士离开我们整整30年了。他的得意门生、亲密朋友刘东生院士也于去年离开了我们,他们间的深情厚谊令人们永远传颂。刘东生1942年毕业于西南联合大学地质地理气象系。早年曾从事抗日救亡工作。1946年2月进入重庆北碚经济部中央地质调查所。7月,他随该所迁回南京。当年年底,李春昱所长找刘东生谈话,对他说：“现在工程地质很重要。这在将来铁路、水坝等工程里是迫切需要的。……”李所长最后提出建议刘东生也从事工程地质研究。

that's GOOD science!

<正>什么是good science?Good science也许被低估了。它可能不是那么华丽炫目,但是它带来革新。它开启了新的可能性。它告知,它启发,它创造。快来加入Takara和Clontech,一次一个实验,一起传颂这些生命科学研究的故事,是它们把世界变得更美好。科学领域,每个决定都有着深远的影响…每个时刻都是一个机遇,把一个实验最深的意义挖掘出来。决定很重要,无论是实验设计还是数据分析。这是我们通过经验确认的;我们是科学家。

Investigation of the mechanism of temperature sensitivity of the electroreceptors of ampullae of lorenzini

In experiments on Black Sea skates (Raja clavata), the potential of the receptor epithelium of the ampullae of Lorenzini and spike activity of single nerve fibers connected to them were investigated during electrical and temperature stimulation. Usually the potential within the canal was between 0 and –2 mV, and the input resistance of the ampulla 250–400 k. Heating of the region of the receptor epithelium was accompanied by a negative wave of potential, an increase in input resistance, and inhibition of spike activity. With worsening of the animal's condition the transepithelial potential became positive (up to +10 mV) but the input resistance of the ampulla during stimulation with a positive current was nonlinear in some cases: a regenerative spike of positive polarity appeared in the channel. During heating, the spike response was sometimes reversed in sign. It is suggested that fluctuations of the transepithelial potential and spike responses to temperature stimulation reflect changes in the potential difference on the basal membrane of the receptor cells, which is described by a relationship of the Nernst's or Goldman's equation type.I.

Principles of organization and evolution of systems of regulation of functions

Evolution of living organisms is closely connected with evolution of structure of the system of regulations and its mechanisms. The functional ground of regulations is chemical signalization. As early as in unicellular organisms there is a set of signal mechanisms providing their life activity and orientation in space and time. Subsequent evolution of ways of chemical signalization followed the way of development of delivery pathways of chemical signal and development of mechanisms of its regulation. The mechanism of chemical regulation of the signal interaction is discussed by the example of the specialized system of transduction of signal from neuron to neuron, of effect of hormone on the epithelial cell and modulation of this effect. These mechanisms are considered as the most important ways of the fine and precise adaptation of chemical signalization underlying functioning of physiological systems and organs of the living organism
