| gene transfer in drosophila melanogaster: cytological alterations in the salivary chromosomes of transformed stocks. | cytological abnormalities are observed in salivary chromosomes of stocks of drosophila melanogaster possessing dna-induced, v+ transformations mapping either at 1-0.0 or 1-33.0. in initial studies, the untransformed control stock and six transformed stocks were assigned code numbers prior to cytological examination. salivary chromosome regions 1b9 10--c 2-3 and 10a1 2--10b1-2 were carefully examined in each of the coded stocks. (band 1b11 is tentatively identified as the site of the suppressor-o ... | 1975 | 807461 |
| blood parasites of some wild bovidae in botswana. | blood smears from a total of 282 wild bovidae from ngamiland, botswana were examined for the presence of blood parasites. the following species were sampled: 190 african buffalo, 23 impala, 10 blue wildebeest, 18 tsessebe, 1 eland, 13 lechwe, 16 kudu and 11 sable antelope. in addition, blood from 36 of the above antelope and from a further 48 buffalo was inoculated into rodents to test for the presence of trypanosomes. an anaplasm morphologically indistinguishable from anaplasma marginale theile ... | 1975 | 813170 |
| analogs of natural lipids. iii. nonequivalence of methyl groups in methylated phospholipids. | the dimethyl esters of a series of diastereoisomeric cyclopentanoid analogs of phosphatidic acid (a.j. hancock, m.h. stokes, and h.z. sable. 1977. j. lipid res. 18: 81-92.) have been studied by proton nmr spectroscopy at 60, 100, and 300 mhz. the signals of the p-o-ch3 protons near delta 3.80 show the expected doubling due to the 31p-1h coupling. in addition, the spectra of three of the isomers show additional multiplicity the line separation (in hz) being proportional to the frequency of the sp ... | 1977 | 833508 |
| in vitro and in vivo antibacterial activity of t-1220, a new semisynthetic penicillin. | t-1220, sodium 6-[d-(-)-alpha-(4-ethyl-2,3-dioxo-1-piperazinylcarbonyl-amino)- alpha-phenylacetamido] penicillanate, is a new semisynthetic penicillin derivative that possesses a broad spectrum of in vitro antibacterial activity against gram-positive and gram-negative bacteria. t-1220 is more effective than carbenicillin (cb-pc) against pseudomonas aeruginosa, klebsiella pneumoniae, proteus species, and serratia marcescens. addition of human serum to culture media did not significantly alter the ... | 1977 | 921239 |
| [skin regeneration in several species of mammals]. | the healing of full-thickness wounds (1.2 cm2) was studied in minks and sables. the wound closure in both animal species resulted mainly from the contraction of the wound. a small regenerate containing hair and sebaceous glands was formed in the centre of the wound. it is supposed that these hairs developed from the old hair roots transfered with the lower layers of the corium adjoining the wound. | 1976 | 953317 |

| modifiers of bx1 alter the distribution of ubx proteins in haltere imaginal discs of drosophila. | the bithorax (bx) mutations in the ultrabithorax (ubx) gene of drosophila melanogaster cause homeotic transformations of anterior third thoracic structures (t3a) toward anterior second thoracic structures (t2a) in the adult fly. a corresponding loss of ubx protein expression in t3a of bx imaginal discs has been observed (white and wilcox, 1985). we describe two genetic loci which modify the bx-induced transformation. a locus which we map very close to the pink peach (pp) gene suppresses the bx1 ... | 1992 | 1601188 |
| splicing of retrotransposon insertions from transcripts of the drosophila melanogaster vermilion gene in a revertant. | a mutation of the drosophila melanogaster vermilion (v) gene known as v1 is caused by the insertion of a 412 retrotransposon into the 5' untranslated region of the first exon. mutants carrying this insertion accumulate a low level of mrna from which most of the transposon sequences have been eliminated by splicing at cryptic sites within transposon sequences. here, we demonstrate that a revertant of the v1 allele called v+37 is caused by the insertion of a second retrotransposon, the b104/roo el ... | 1991 | 1664404 |
| the drosophila suppressor of sable gene encodes a polypeptide with regions similar to those of rna-binding proteins. | the nucleotide sequence of the drosophila melanogaster suppressor of sable [su(s)] gene has been determined. comparison of genomic and cdna sequences indicates that an approximately 7,860-nucleotide primary transcript is processed into an approximately 5-kb message, expressed during all stages of the life cycle, that contains an open reading frame capable of encoding a 1,322-amino-acid protein of approximately 150 kda. the putative protein contains an rna recognition motif-like region and a high ... | 1991 | 1703632 |
| mutations in the su(s) gene affect rna processing in drosophila melanogaster. | we have studied the effect of mutations in the suppressor of sable [su(s)] gene on p element-induced yellow alleles. two independent mutations tested, y76d28 and y1#7, contain a 1.1-kilobase (kb) p element inserted in the 5' transcribed untranslated portion of the yellow gene. sequences responsible for the y1#7 mutation are inserted in the same transcriptional orientation as yellow and cannot be processed by splicing, and this mutation is not suppressed by su(s) mutations. p element sequences ar ... | 1991 | 1714588 |
| non-invasive assessment of the incidences of pregnancy and pregnancy loss in the feral horses of sable island. | field observations of 400 totally unmanaged feral horses on sable island, nova scotia, were complemented by oestrogen determinations in faecal samples from 154 identified females over a 4-year period (454 mare-years). of mares that were sampled throughout the year and subsequently produced foals, 92.1% exhibited elevated faecal oestrogens between 15 october and 30 march. the results confirm that faecal oestrogens are a useful indicator of pregnancy after approximately 120 days gestation. distrib ... | 1991 | 1795292 |
| present status of trichinellosis in japan. | there have been three mass outbreaks of human trichinellosis in japan. the first was in 1974 in iwasaki, aomori prefecture, involving a group of hunters who ate raw meat of a black bear they had shot. of the 20 people who ate the bear meat raw, 15 showed clinical symptoms of trichinellosis. the second outbreak was experienced in sapporo, hokkaido, in 1980. the patients had eaten the raw meat of a brown bear served in a local restaurant. twelve people were diagnosed positive on the basis of clini ... | 1991 | 1822910 |
| mobile element insertions causing mutations in the drosophila suppressor of sable locus occur in dnase i hypersensitive subregions of 5'-transcribed nontranslated sequences. | the locations of 16 mobile element insertions causing mutations at the drosophila suppressor of sable [su(s)] locus were determined by restriction mapping and dna sequencing of the junction sites. the transposons causing the mutations are: p element (5 alleles), gypsy (3 alleles), 17.6, hms beagle, springer, delta 88, prygun, stalker, and a new mobile element which was named roamer (2 alleles). four p element insertions occur in 5' nontranslated leader sequences, while the fifth p element and al ... | 1990 | 1963868 |
| relation of cortical cell orientation selectivity to alignment of receptive fields of the geniculocortical afferents that arborize within a single orientation column in ferret visual cortex. | neurons in the primary visual cortex of higher mammals are arranged in columns, and the neurons in each column respond best to light-dark borders of particular orientations. the basis of cortical cell orientation selectivity is not known. one possible mechanism would be for cortical cells to receive input from several lateral geniculate nucleus (lgn) neurons with receptive fields that are aligned in the visual field (hubel and wiesel, 1962). we have investigated the relationship between the arra ... | 1991 | 2027051 |
| an outbreak of babesiosis in imported sable antelope (hippotragus niger). | a complete necropsy performed on 2 sable antelope (hippotragus niger), revealed lesions concomitant with a massive haemolytic crisis. these included widespread oedema and anaemia of the carcass, severe oedema of the lungs, petechiae and echymoses of the epicardium, a moderate splenomegaly and a severe haemoglobinuria. the histopathological lesions included a moderate alveolar oedema, the presence of haemosiderin in the spleen and lymph nodes, and mild degenerative changes of the renal tubular ep ... | 1991 | 2051446 |
| albino gene dosage and retinal decussation patterns in the pigmented ferret. | we have examined the retinal decussation patterns in pigmented ferrets that were either wild-type sable or heterozygous with one albino gene. unilateral injections of horseradish peroxidase were made into the optic tract and labeled ganglion cells visualized in retinal wholemounts. in both wild-type and heterozygous ferrets, those ganglion cells in the temporal retina with the largest cell bodies projected only to the contralateral side of the brain. the total number of ipsilaterally projecting ... | 1991 | 2059573 |
| structure and transcription of the drosophila melanogaster vermilion gene and several mutant alleles. | the nucleotide sequence and intron-exon structure of the drosophila melanogaster vermilion (v) gene have been determined. in addition, the sites of several mutations and the effects of these mutations on transcription have been examined. the major v mrna is generated upon splicing six exons of lengths (5' to 3') 83, 161, 134, 607, 94, and 227 nucleotides (nt). a minor species of v mrna is initiated at an upstream site and has a 5' exon of at least 152 nt which overlaps the region included in the ... | 1990 | 2108317 |
| a retrotransposon 412 insertion within an exon of the drosophila melanogaster vermilion gene is spliced from the precursor rna. | three alleles of the drosophila melanogaster vermilion (v) gene are suppressed by recessive mutations at the suppressor of sable [su(s)], gene. previous work has established that these alleles have identical insertions of the 412 retrotransposon in the 5'-untranslated region of the gene. despite the transposon insertion in an exon, v mutants accumulate trace amounts of apparently wild-type-sized transcripts in a su(s)+ background, and the level of v transcript accumulation is increased by su(s) ... | 1990 | 2163342 |
| dorothea dix and her two missions of mercy in nova scotia. | dorothea lynde dix, 19th century defender of the rights of the mentally ill to hospital care, holds a significant place in the history of nova scotia. her two major accomplishments in this province include laying the groundwork for its first psychiatric hospital and the outfitting of treacherous sable island with rescue equipment to aid ships stranded off its shore. the techniques that miss dix employed in these missions parallel those she successfully used in the establishment of psychiatric ho ... | 1990 | 2180553 |
| purkinje cell simple spike activity during grasping and lifting objects of different textures and weights. | 1. three monkeys (2.5-3.5 kg) were trained to pinch an object between the thumb and forefinger and to lift it a vertical distance of 1.0-2.0 cm. either the object weight (15, 65, or 115 g) or the surface texture (sand paper or polished metal) contacting the fingers could be varied. the object was equipped with a vertical position transducer, an accelerometer, and strain gauges that measured the grip force and the vertical load force. 2. in accordance with similar previously published studies on ... | 1990 | 2230918 |
| effects of pasteurella haemolytica leukotoxin on neutrophils from white-tailed deer and several exotic ruminant species. | pasteurella haemolytica leukotoxin is a pore-forming cytolysin which acts as a virulence factor in pasteurellosis of domestic ruminants. leukocytes from cattle, sheep and goats are susceptible to leukotoxin-induced lysis; however, leukocytes from non-ruminant species so far tested are resistant to leukotoxin-induced lysis. neutrophils obtained from three white-tailed deer, four saiga antelope, an addra gazelle, a grant's gazelle and a sable antelope were tested for susceptibility to the lytic ef ... | 1990 | 2382402 |
| molecular and genetic organization of the suppressor of sable and minute (1) 1b region in drosophila melanogaster. | recessive mutations at the suppressor of sable [su(s)] locus in drosophila melanogaster result in suppression of second site mutations caused by insertions of the mobile element 412. in order to determine whether su(s) mutations might have other phenotypes, a saturation mapping of the su(s) region was carried out. the screen yielded 76 mutations that comprise ten genetic complementation groups ordered distal to proximal as follows: l(1)1bh, l(1)1bi, m(1)1b, su(s), l(1)1bk, l(1)1ca, mul, tw, l(1) ... | 1989 | 2503417 |
| experimental infection of eland (taurotrages oryx), sable antelope (ozanna grandicomis) and buffalo (syncerus caffer) with foot-and-mouth disease virus. | the course of experimental infection of a type sat 1 fmdv strain was studied in buffalo, sable antelope and eland following tongue inoculation and contact and has been compared with that in cattle. all species became infected, although disease was less severe in the game animals and larger amounts of virus were required to infect game animals than cattle. neutralizing antibody titres were high and were maintained for an extended period in buffalo, sable antelope and eland. the carrier state was ... | 1989 | 2584449 |
| mixed function oxidase activity in the harbour seal (phoca vitulina) from sable is., n.s. | one adult male, eight pups (including two full term foetuses) and nine adult female harbour seals (phoca vitulina) were analysed for indices of mixed function oxidase (mfo) activity. mfo activity was present in liver samples, but was at or below detection limits in samples of kidney, lung and pancreas. hepatic ethoxyresorufin o-de-ethylase and benzo[a]pyrene hydroxylase activities were similar to those reported in other seals and in other mammals. cytochromes p-450 and b5 concentrations were sli ... | 1986 | 2877778 |
| molecular characterization of the drosophila vermilion locus and its suppressible alleles. | we have cloned vermilion (v), one of the genes required for brown eye pigment synthesis in drosophila, using a mutant (vh2a) "tagged" with the transposon p factor. mutations that disrupt v gene expression are clustered within approximately 2 kilobases of dna. a 1.4-kilobase transcript, homologous to this same region, is present in v+ rna but absent in rna from several v mutants. the spontaneous v alleles that are suppressed by the suppressor of sable [su(s)] are apparently identical insertions o ... | 1986 | 3001735 |
| molecular cloning of suppressor of sable, a drosophila melanogaster transposon-mediated suppressor. | a hybrid dysgenesis-induced allele [su(s)w20] associated with a p-element insertion was used to clone sequences from the su(s) region of drosophila melanogaster by means of the transposon-tagging technique. cloned sequences were used to probe restriction enzyme-digested dnas from 22 other su(s) mutations. none of three x-ray-induced or six ethyl methanesulfonate-induced su(s) mutations possessed detectable variation. seven spontaneous, four hybrid dysgenesis-induced, and two dna transformation-i ... | 1986 | 3023894 |
| reinforcers in infancy: classical conditioning using stroking or intra-oral infusions of milk as ucs. | six-day-old rats received 20 forward pairings of an odor-conditioned stimulus (cs) with one of two unconditioned stimuli (ucs); 1) intra-oral milk infusions or 2) stroking with a sable-hair brush. these ucs's produce a common general response of increased behavioral activity, but different specific behaviors. for each ucs, additional pups received backward pairings of the cs and ucs, random pairings of the cs and ucs, cs only, ucs only, or no stimuli. four hours later, pups received a two-odor c ... | 1988 | 3371554 |
