A Tilden et al.
Melatonin was injected into intact and eyestalk-ablated fiddler crabs (Uca pugilator), and its effects on hemolymph glucose and lactate levels were studied. In intact crabs, glucose and lactate levels cycled simultaneously, with peaks occur...

J C Raine
The effect of injected bovine TSH on the pattern of anti-T(4) and anti-T(3) immunostaining of the thyroid tissue was examined in rainbow trout (Oncorhynchus mykiss) and medaka (Oryzias latipes) to determine if the previously reported immuno...
Retinal photoreceptors and visual pigments in Boa constrictor imperator [0.03%]

The photoreceptors of Boa constrictor, a boid snake of the subfamily Boinae, were examined with scanning electron microscopy and microspectrophotometry. The retina of B. constrictor is duplex but highly dominated by rods, cones comprising 1...
Transport of (22)Na(+) and( 45)Ca(2+) by Xenopus laevis oocytes expressing mRNA from lobster hepatopancreas [0.03%]

This paper describes the development of a functional assay system to express crustacean epithelial electrogenic 2Na(+)/1H(+) antiporters in Xenopus laevis oocytes. Subsequent publications will use this assay method to establish nucleotide a...
Modulation of fish phagocytic cells by N-terminal peptides of proopiomelanocortin (NPP) [0.03%]
前脑啡肽原N端肽对鱼吞噬细胞的调节作用
M Sakai,T Yamaguchi,H Watanuki et al.
M Sakai et al.
N-terminal peptide of proopiomelanocortin (NPP, or pro-gamma-MSH) has shown to exhibit biological activity such as stimulation of adrenal mitogenesis and prolactin release-inhibiting factor activity. Structurally, studies reveal a significa...
Sex-linked genes are not silenced in fetal bovine testes expressing X-inactive specific transcript (XIST) [0.03%]
雄性牛胎睾丸表达X染色体失活特异转录本(XIST)，但未发生基因沉默现象
A Farazmand,W Koykul,J Peippo et al.
A Farazmand et al.
X-inactive specific transcript (XIST), which is thought to be the central factor for the X-inactivation process in female mammals, is known to be expressed in males during spermatogenesis. Our studies have shown that XIST is not only expres...
Does one gene determine whether a C57BL/6J-Y(POS) mouse will develop as a female or as an hermaphrodite? [0.03%]
一个基因决定C57BL/6J-Y(POS)小鼠是发育成雌性还是雄雌两性吗？
E M Eicher,L L Washburn
E M Eicher
Two studies were conducted to further our understanding of the inherited condition in mice known as C57BL/6J-Y(POS) (B6-Y(POS)) sex reversal. One study determined what proportion of B6 XY(POS) mice develop as females or hermaphrodites. We f...

In this study we test the hypothesis that lung reduction in amphibians is a larval adaptation to reduce buoyancy and facilitate rheotaxis in lotic environments. Larvae of the spotted salamander Ambystoma maculatum (family Ambystomatidae) we...

Developmentally arrested brine shrimp cysts have been reactivated during orbital spaceflight on two different Space Shuttle missions (STS-50 and STS-54), and their subsequent development has been compared with that of simultaneously reactiv...
Insect gravitational biology: ground-based and shuttle flight experiments using the beetle Tribolium castaneum [0.03%]
昆虫重力生物学：利用红谷盗进行的地面和航天飞机飞行实验
