Immunolocalization of proacrosin/acrosin in bovine sperm and sperm penetration through the zona pellucida
(ELSEVIER SCIENCE BV, 2000-03-15)
The aim of the present work was to immunolocalize acrosin in bull spermatozoa incubated for up to 6 h in capacitating culture medium (TALP-heparin), in order to study the kinetics of its release during the acrosome reaction ...
Human respiratory syncytial virus genomic and antigenic variants isolated in two hospitals during one epidemic, in Santiago, Chile
(ELSEVIER, 2008-07)
Background: Human respiratory syncytial virus (HRSV) is a major cause of severe lower respiratory tract infection (LRI) in children. Distinct variants of the viruses have been described.
Objective: The objective was to ...
Comparison of immunofluorescence, enzyme immunoassay and cell culture for the diagnosis of Chlamydia trachomatis in urogenital infections Comparación de la inmunofluorescencia, ensayo inmunoenzimático y cultivo celular para el diagnóstico de Chlamydia tra
(1991)
We evaluated the usefulness of the direct immunofluorescence test with monoclonal antibodies and the enzyme immunoassay in comparison with isolation in cell cultures for the diagnosis of Chlamydia trachomatis in 55 ...
Melanocortin 1 receptor is expressed by uveal malignant melanoma and can be considered a new target for diagnosis and immunotherapy
(2007)
PURPOSE. Uveal melanoma is the most common primary malignant
ocular cancer in adults. This tumor has a distinct expression
pattern of markers compared with cutaneous melanoma.
MC1R is under study as a potential target ...
An intramolecular O-N migration reaction on gold surfaces: Toward the preparation of well-defined amyloid surfaces
(2009)
Amyloids are a family of self-aggregating proteins implicated in various central nervous system disorders, including Alzheimer's disease (AD). It is thought that prefibrillar soluble forms of amyloid peptides, including ...
Comparative evaluation of three different ELISA assays and HPLC-ESI-ITMS/MS for the analysis of N-epsilon carboxymethyl lysine in food samples
(Elsevier, 2018)
N-epsilon-carboxymethyl-lysine (CML) is measured in food, but there is a controversy concerning the most convenient yet reliable method(s) for this task. This work compares three different ELISA assays and HPLC-ESI-ITMS/MS ...
ApoE alleles and tau markers in patients with different levels of cognitive impairment
(ELSEVIER SCIENCE INC, 2005-09)
Background. The presence of brain hyperphosphorylated tau constitutes a hallmark of neurodegenerative disorders of the Alzheimer's type. This report describes the relationships between tau markers in the cerebrospinal fluid ...
Matrix metalloproteinase-13 is highly expressed in destructive periodontal disease activity
(American Academy of Periodontology, 2006-11)
Background: Matrix metalloproteinases (MMPs) participate in extracellular matrix degradation in physiological and pathological conditions. The available evidence suggests that MMP-13 plays a significant role in both the ...
Differential expression of GDF-9 and BMP- 15 duringfollicular development in canine ovaries evaluated by flowcytometry
(Elsevier, 2016)
Growth differentiation factor 9 (GDF-9) and bone morphogenetic protein 15 (BMP-15) playimportant functions in follicular and oocyte development in many species. This study eval-uated the dynamic expression of GDF-9 and ...
Aqueous two-phase systems for protein separation: Phase separation and applications
(2010)
Aqueous two-phase systems (ATPS) that are formed by mixing a polymer (usually polyethylene glycol,
PEG) and a salt (e.g. phosphate, sulphate or citrate) or two polymers, and water can be effectively used
for the separation ...
