    Notes: Leptomonas lactosovorans n. sp. is described from the gut of the reduviid hemipteran Zelurus martinsi. It can be grown in a defined medium. The requirements for amino acids, vitamins, purine, and heme were similar to those established for Crithida fasciculata. Growth is stimulated by aeration. Generation time is longer than for any other insect trypanosomatid described; its utilization of lactose as a carbon source is a unique feature among trypanosomatids.

    Notes: SUMMARY-The development of food mixtures containing vegetable protein concentrates, minerals, and vitamins represents an important approach to the problem of protein-calorie malnutrition of preschool children in many parts of the world. In Brazil, soy flour is the most readily available good-quality protein for this purpose. Protein efficiency-ratio studies in rats demonstrated that soy flour with a PER value of 1.99 was available in large quantities. Accordingly, a formula containing 19.50% soy flour, 4.50% nonfat milk powder, 32.28% corn starch, 39.00% sucrose, and 4.72% vitamins and minerals was thoroughly tested as an infant food. The PER value of the protein in rats was 2.31. Amino acid assay demonstrated that the protein compared favorably with the essential amino acid pattern of the FAO/WHO reference protein (FAO/WHO, 196.5) except for methionine-cystine, The formula was well accepted and tolerated by children and adults. Average nitrogen absorption and retention of the formula as the sole food of malnourished children were 72.68 and 23.82%; values for milk protein were 80.17 and 30.13%. Average nitrogen absorption and retention were 63.4 and 22.0% when the formula provided one-half (15 g) of the daily protein for normal children consuming a typical diet of the region, comparing favorably with values of 69.3 and 21.3% for milk protein.

    HLA, AND THE RESPONSE TO TREATMENT WITH γ-TYPE ENDORPHINS IN SCHIZOPHRENIA (1982)
    Oxford, UK : Blackwell Publishing Ltd
    International journal of immunogenetics 9 (1982), S. 0 
    Details

    Notes: In order to investigate whether genetic factors are involved in the response of schizophrenic patients to treatment with γ-type endorphins, we typed 32 Dutch schizophrenic patients for the HLA-A, -B, -C and -DR antigens. The total patient group showed an increase of HLA-Bw4 and HLA-Cw1. A subgroup of 20 paranoid patients showed an increase of HLA-Cw1 and a significant heterogeneity for the HLA-C locus. In 16 patients who responded moderately or markedly to treatment with γ-type endorphins, an increase of HLA-B15/Cw3 and a decrease of HLA-B17 were found as compared to 16 patients with no or a slight response. Moreover, HLA-B15 was particularly increased in those patients who responded markedly and remained free of psychotic symptoms for a period of at least 6 months after treatment with γ-type endorphins (RR = 24.6, Puncorr.= 0.0015).Our results suggest that genetic factors coded for within the HLA region are associated with paranoid schizophrenia, and that HLA-B15/Cw3 is associated with a marked and prolonged response to treatment with γ-type endorphins.

    GENETICS OF CHINESE HAMSTER MIXED LYMPHOCYTE REACTIVITY (1980)
    Oxford, UK : Blackwell Publishing Ltd
    International journal of immunogenetics 7 (1980), S. 0

    Notes: Two-way and one-way mixed lymphocyte cultures (MLC) with Chinese Hamster peripheral blood lymphocytes were performed. Reduction of the culture surface and addition of 2-mercaptoethanol to the culture medium gives a marked enhancement of the reactivity of low numbers of lymphocytes in the MLC. Genetic analysis of the mixed lymphocyte reactivity (MLR) in the animals studied so far indicates that three or four different alleles are involved. Howerver, not all phenotypes could be traced. The samples of different stocks of Chinese Hamsters in Europe and the United States did not all share the same alleles and the samples were also different as regards the relative frequency of phenotypes. For DNA inhibition in stimulating cells mitomycin C treatment is less suitable than irradiation. Skin graft survival time was longer in animals which showed no MLR than in animals with a positive MLR.

    Entamoeba histolytica: Collagenolytic Activity and Virulence (1984)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 31 (1984), S. 0 
    Details
    ISSN: 1550-7408
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Several axenic strains of pathogenic and nonpathogenic Entamoeba histolytica were tested for their capacity to digest native radioactive type I collagen gels and to produce liver abscesses when injected into the liver of newborn hamsters. The results demonstrate that the pathogenic strains of amebas (HM1:IMSS, HM3:IMSS, HM38:IMSS, and HK9) have a collagenolytic activity that closely correlates with their in vivo capacity to produce liver lesions. The nonpathogenic isolate (Laredo) did not show collagenolytic activity and failed to produce lesions in the liver of newborn hamsters. The results also demonstrate that type I collagen obtained from rodents and cats is degraded less by amebic collagenase than is bovine collagen, which is similar to human collagen. These findings suggest that species susceptibility to invasive infection may depend, among other factors, on the characteristics of the extracellular components of host tissues.

    A Comparative Study of 14 Strains of Naegleria australiensis Demonstrates the Existence of a Highly Virulent Subspecies: N. australiensis italica n. spp. (1984)

    The @journal of eukaryotic microbiology 31 (1984), S. 0 
    Details
    ISSN: 1550-7408
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Fourteen strains of Naegleria australiensis, including the type strain, were compared for virulence for mice, maximum growth temperature, lectin agglutination, isoenzyme pattern, and total protein banding pattern. Their relation to other species of Naegleria also was compared by immunoelectrophoretic analysis. Strains with high virulence, comparable to that of N. fowleri, were found to be different in concanavalin A agglutination as well as with regard to zymograms and total protein patterns. Although serologically different from N. fowleri and reacting with N. australiensis antiserum in the fluorescent antibody test, these high-virulence strains differed in number of immunoelectrophoretic precipitin bands. Because of these results, the high-virulence strains are considered to be a subspecies of N. australiensis. The low-virulence strains showed minor differences from the type strain. Thus, N. australiensis does not appear to be as homogenous a species as N. fowleri. Pathogenic N. australiensis also seems to be more widespread than previously thought.

    Cortical Control over the Direction of Macronuclear Elongation in the Heterotrich Ciliate Stentor coeruleus (1983)
    Oxford, UK : Blackwell Publishing Ltd

    Details
    ISSN: 1550-7408
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Earlier experimental work involving macronuclear implants in Stentor coeruleus has shown that the cytoplasmic cortex of the nuclear site 1) attracts the macronucleus and 2) holds it in place during interphase. Now experiments indicate macronuclei transferred with overlying cortex elongate in the direction of the transferred cortical pigment stripes, whether or not the transferred stripes realign in the direction of the host stentor's stripes. Therefore the third function of the cortex is to determine the direction of elongation and thus assure that both daughter cells at division receive part of the macronucleus.

    Fine Structure and Cytochemistry of the Nucleus and the Kinetoplast of Epimastigotes of Trypanosoma cruzi (1983)

    Notes: . Ultrastructural cytochemical techniques were used to analyze the nucleus and the kinetoplast of epimastigotes of Trypanosoma cruzi. With the use of ethanolic phosphotungstic acid, which detects basic proteins, reaction product was seen in the chromatin and at the periphery of the kinetoplast. Thallium alcoholate, which interacts with DNA, stained strongly the whole kinetoplast and the chromatin. With the use of a silver impregnation method that detects acidic nucleolar proteins, silver granules were seen preferentially located in the central region of the nucleolus. With the EDTA method, which reveals the presence of ribonucleoproteins, staining was observed in the nuclear pores. Also 6–8 nm fibrils, 25 nm and 40 nm granules, which correspond to the perichromatin fibers, interchromatin granules and the perichromatin granules, respectively, were identified in the nucleus. The EDTA method also revealed the presence of 40 nm granules in the kinetoplast. These granules were seen mainly at the two extremities of the kinetoplast. Freeze-fracture images indicate that the nuclear membrane contains ca. 9 pores/μm2 of nuclear surface area. The mean diameter of the pores was 80 nm. All these results suggest that epimastigotes of T. cruzi have a very active nucleus and a high rate of nucleocytoplasmic interchange.

    Topics: Biology
    Notes: Fine structural studies of the hydrogenosomes of Tritrichomonas foetus using an improved fixative reveal that they are enclosed by two closely apposed 6 nm membranes, which separate at some regions forming a large intramembranous vacuole where Ca++-binding sites are located. Fixation of the cells in a glutaraldehyde solution containing 5 mM CaCl2 and postfixation in an osmium tetroxide-potassium ferrocyanide solution led to the appearance of a reaction product associated with certain regions of the membrane of the hydrogenosomes and in the cisternae of the endoplasmic reticulum, in the recurrent flagellum, and in the plasma membrane. Treatment of ultrathin sections with EGTA removed the reaction product. These results, in association with others previously described, indicate the existence of several similarities between the hydrogenosomes and the mitochondria.
