the chloroform soluble fractions of ethanolic extracts of five inula belonging to the compositae family were evaluated for cytotoxic activity against five different cell lines including caco2 (human colon adenocarcinoma), mcf7 (human breast adenocarcinoma), hepg2 (human hepatocellular carcinoma), vero (green african monkey kidney) and wehi164 (balb c mouse fibrosarcoma). cytotoxicity was assess...

An α7 nicotinic acetylcholine receptor sequence was cloned from Rhesus monkey (Macaca mulatta). This clone differs from the mature human α7 nicotinic acetylcholine receptor in only four amino acids, two of which are in the extracellular domain. The monkey α7 nicotinic receptor was characterized in regard to its functional responses to acetylcholine, choline, cytisine, and the experimental α7-se...

BACKGROUND AND AIMS A deviation from the classical beetle pollination syndrome of dull-coloured flowers with an unpleasant scent is found in the Greater Cape Floral Region of South Africa. Here, monkey beetles (Scarabaeidae) visit brightly coloured, odourless flowers with conspicuous dark spots and centres (beetle marks). The role of flower colour and markings in attracting monkey beetles is st...

Light microscopic autoradiography with 3H-thymidine was used as a probe for DNA synthesis on the retinas of the guinea pig, rabbit, and monkey. Relatively heavy labeling was found in the ganglion cell and inner nuclear layers as well as in the photoreceptor inner segments in the guinea pig and monkey. Electron microscopic autoradiography demonstrated that in the ganglion cells and photoreceptor...

Chicken embryo lethal orphan (CELO) virus replication studies in adult hamster kidney and green monkey kidney cell cultures by means of infectivity, cytochemistry, and fluorescent-antibody techniques indicated that replication in hamster kidney cells was limited to the production of neoantigen. Production of virus in green monkey kidney cells was limited but appeared to exceed the production of...

PURPOSE The purpose of this study was to detect and establish the cellular localizations of nicotinic acetylcholine receptor (nAChR) subunits in Rhesus monkey retina. METHODS Retinas were dissected from the eyes of monkeys killed after unrelated experiments. RNA was extracted and analyzed by RT-PCR, using primers designed against human sequences of alpha3-alpha7, alpha9, and beta2-beta4 nAChR...

E-2078 is a dynorphin A (1-8) analog, [N-methyl-Tyr1, N-methyl-Arg7-D-Leu8] Dyn A (1-8) ethylamide. Its biochemical stability against enzymatic degradation in vitro in human and rhesus monkey blood, and in vivo in rhesus monkey blood was studied using matrix-assisted laser desorption/ionization mass spectrometry. In vitro studies were carried out in freshly drawn human and rhesus monkey blood, ...

Shape and texture are both important properties of visual objects, but texture is relatively less understood. Here, we characterized neuronal responses to discrete textures in monkey inferotemporal (IT) cortex and asked whether they can explain classic findings in human texture perception. We focused on three classic findings on texture discrimination: 1) it can be easy or hard depending on the...

1. A neurotropic murine virus was isolated by passing poliomyelitis virus (SK strain) from the monkey to cotton rats and white mice. 2. The murine virus has been grown in tissue culture consisting of embryonic mouse brain in ox serum ultrafiltrate. 3. The symptoms and lesions produced by the murine infection compare in all respects with those of poliomyelitis in monkey and man. 4. The murine vi...

The metabolism of cholesterol was studied in baboons, rhesus monkeys, and squirrel monkeys while they were being fed either a low fat, low cholesterol (basal) diet or the basal diet supplemented with saturated fat and cholesterol (atherogenic diet). When the diet was changed from basal to atherogenic, the mean total serum cholesterol concentration increased from 70 to 180 mg/dl in the baboon, f...
