Published 2005Staff ViewISSN: 1399-3038Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Ataxia telangiectasia (AT) is an infrequent condition, which is difficult to diagnose in children. The objective was to describe the evolution of all affected patients controlled in our hospital and to highlight the keys for an early diagnosis considering the variability of immunological disorders. The present study is a retrospective review of all patients diagnosed and controlled of AT in our hospital. Twelve patients were found, including two couples of siblings. The most frequent reason for consultation was unstable gait. Seven patients suffered repeated infections, being pneumonia the most frequent cause of infection, followed by sinusitis. One of the patients developed Burkitt's lymphoma, and another patient, Hodgkin's lymphoma, which caused the death of the patient at the age of 11. A couple of siblings aged 17 and 22 years developed insulin-resistant diabetes mellitus. The most frequent immunity disorders were the IgG deficiency and the decrease of T lymphocytes. Seven patients were treated with non-specific gamma-globulin. By the end of the follow-up, 8 patients (ages ranged 7 to 12 years) lost gait. Molecular genetic testing was conducted in patients who are still cared for in our hospital. Clinical suspicion of this entity will lead to an early diagnosis, the treatment of complications, and to provide genetic counselling for the families.Type of Medium: Electronic ResourceURL: -

ISSN: 1750-3841Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionProcess Engineering, Biotechnology, Nutrition TechnologyNotes: An acid-tolerant fungus, Scytalidium acidophilum, was cultivated in peat extract for potential use as a single-cell protein (SCP) source. In shake flask fermentations with a 0.3% yeast extract diluted peat extract medium, it was found that the best conditions for growth occurred at pH 2.0 and 25°C. The maximum biomass concentration was produced after 10 days, with no significant differences for agitation rates between 100 and 200 rpm. Microbial contamination was not observed in nonaseptic operations. The protein content and amino acid composition of the mycelium produced compares with those reported for S. acidophilum grown in other fermentation media. The advantages of growing S. acidophilum in acid peat extract are presented.Type of Medium: Electronic ResourceURL: -

Published 1986Staff ViewISSN: 1748-7692Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: BiologyNotes: The apparent lack of significant recovery of western North Atlantic right whale populations may be related to the availability of prey in exploitable densities. We have attempted to estimate the concentration of zooplankton required by right whales to obtain a net energetic benefit over the long term, using estimated values for body weight, metabolic rate, assimilation efficiency, time spent feeding, mouth size and swimming speed. The estimated range of required energy densities is 7.57 to 2,394 kcal m−3 (3.17 × 104 to 1.00 × 107 joule m−3). These values are from one to more than three orders of magnitude greater than the densest concentration sampled in the vicinity of right whale aggregations in the Great South Channel. Right whales must seek out and exploit extremely dense patches of prey organisms in order to feed efficiently. The presence of such dense patches of zooplankton is likely to be a primary characteristic of spring, summer and fall right whale habitats.Type of Medium: Electronic ResourceURL: -

The determination of pectin content utilizing the ethanol yield method and the calcium pectate method was conducted in 13 and 7 tropical fruits, respectively. The variation in pectin content from the green to the mature and to the ripe stages was determined in 6 fruits. Finally, estimation of the percentage of methoxylation, as an indication of the gel forming potential of the pectin, was measured in 3 of the most promising pectin source fruits.Type of Medium: Electronic ResourceURL: -

Natural killer (NK) immunoglobulin-like receptors (KIRs) are a family of polymorphic receptors which interact with specific motifs on HLA class I molecules and modulate NK cytolytic activity. In this study, we analyzed a recently sequenced subgenomic region on chromosome 19q13.4 containing eight members of the KIR receptor repertoire. Six members are clustered within a 100-kb continuous sequence. These genes include a previously unpublished member of the KIR gene family 2DS6, as well as 2DL1, 2DL4, 3DL1, 2DS4, 3DL2, from centromere to telomere. Two additional KIR genes, KIRCI and 2DL3, which may be located centromeric of this cluster were also analyzed. We show that the KIR genes have undergone repeated gene duplications. Diversification between the genes has occurred postduplication primarily as a result of retroelement indels and gene truncation. Using pre- and postduplication Alu sequences identified within these genes as evolutionary molecular clocks, the evolution and duplication of this gene cluster is estimated to have occurred 30–45 million years ago, during primate evolution. A proposed model of the duplication history of the KIR gene family leading to their present organization is presented.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-072XKeywords: Penicillium simplicissimum ; Species description ; Phenolic compounds ; Phloroglucinol ; Aerobic degradationSource: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Abstract The pathway for the aerobic catabolism of 1,3,5-trihydroxybenzene (phloroglucinol) by a new strain of Penicillium was investigated using both in vivo and in vitro cell-free systems. The fungal strain was isolated by enrichment on phloroglucinol and identified as P. simplicissimum (Oud) Thom. It grew optimally at pH 5.5 and 27°C with 119 mM (1.5%w/v) of phloroglucinol in a basal mineral salts medium. Vapours of the crystalline substrate placed in a Petri-plate lid supported the growth of the fungal colonies on the agar surface. Mycelia grown on phloroglucinol accumulated 1,2,4-trihydroxybenzene and resorcinol in the medium. Washed, resting mycelia grown on phloroglucinol, when resuspended in a buffer utilized oxygen in the presence of catechol, resorcinol, pyrogallol and phloroglucinol. A NADPH-dependent reductase in the cell-free extract reduced phloroglucinol to dihydrophloroglucinol. This electron donor could not be replaced by NADH. Resorcinol hydroxylase, phloroglucinol reductase, catechol-1,2-oxygenase, and catechol-2,3-oxygenase were detected in cell-free extracts of mycelia grown on phloroglucinol. The possible steps in the degradation of phloroglucinol are discussed.Type of Medium: Electronic ResourceURL: -

Published 1996Staff ViewISSN: 1573-7284Keywords: Clinical manifestations ; Diagnosis ; Epidemiology ; HIV-1 ; HTLV-I ; HTLV-IISource: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Abstract The human T-lymphotropic virus type II (HTLV-II) has recently been associated with the genesis of some subacute neurological syndromes and, rarely, with atypical T-lymphoid malignancies. The virus is endemic in some Amerindian and African tribes, and among intravenous drug users (IDUs) in North America and Europe. Given that HTLV-II is transmitted by the same routes as other human retroviruses, the screening of antibodies to HTLV-II in blood donors has became a matter of controversy in some countries. Herein, we describe the clinical, epidemiological and virological features of 113 individuals with HTLV-II infection identified in Spain up to September 1995. Most of them (94/113; 83%) were male, and all but seven were natives. Four were African immigrants living in Madrid and 3 had been born in other European countries. All but six subjects were IDUs, and sexual transmission of HTLV-II and transfusion were involved in five and one individual, respectively. Eighty-four percent of the IDUs infected with HTLV-II were co-infected by HIV-1 (93/107). Clinical manifestations potentially linked to HTLV-II were absent, although an IDU male co-infected by HIV-1 and HTLV-II developed a severe non-inflammatory proximal myopathy. In conclusion, HTLV-II infection is present in Spain, mainly among IDUs, with a growing incidence and a current overall prevalence of 2.0 percent.Type of Medium: Electronic ResourceURL:
