Does math self-efficacy mediate the effect of the perceived classroom environment on standardized math test performance?
We examined the effect of the perceived classroom environment on math self-efficacy and the effect of math self-efficacy on standardized math test performance. Upper elementary school students (N =Expand
Activation of mouse sperm T-type Ca2+ channels by adhesion to the egg zona pellucida.
The sperm acrosome reaction is a Ca(2+)-dependent exocytotic event that is triggered by adhesion to the mammalian egg's zona pellucida. Previous studies using ion-selective fluorescent probesExpand
The mechanistic basis of aerobic performance variation in red junglefowl.
We examined aerobic performance, organ and muscle mass and enzymatic activity in red junglefowl (Gallus gallus). We tested three models of performance limitation (central limits, peripheral limits,Expand
Detection of nucleic acid hybridization by nonradiative fluorescence resonance energy transfer.
Three approaches were used to study hybridization of complementary oligodeoxynucleotides by nonradiative fluorescence resonance energy transfer. (i) Fluorescein (donor) and rhodamine (acceptor) wereExpand
Con Carino: Teacher Caring, Math Self-Efficacy, and Math Achievement among Hispanic English Learners.
Background/Context: How do we account for the persistence of below-average math test score performance among California Hispanics who are fluent in English, as well as Spanishdominant EnglishExpand
The acrosomal vesicle of mouse sperm is a calcium store
Subsequent to binding to the zona pellucida, mammalian sperm undergo a regulated sequence of events that ultimately lead to acrosomal exocytosis. Like most regulated exocytotic processes, a rise inExpand
Metabolic regulation in mammalian sperm: mitochondrial volume determines sperm length and flagellar beat frequency.
In the absence of glycolytic support, mammalian sperm derive their energy for motility from a densely packed array of mitochondria at the base of the flagellum known as the midpiece. Using data onExpand
The Initial Molecular Interaction between Mouse Sperm and the Zona Pellucida Is a Complex Binding Event*
Prior to fertilization, mammalian sperm must first bind to the zona pellucida (ZP), a glycoprotein matrix surrounding the egg. Sperm specifically bind to ZP3, an 83-kDa glycoprotein which functionsExpand
Biochemical characterization of a glycosylphosphatidylinositol-linked hyaluronidase on mouse sperm.
On the basis of DNA homology to bee venom hyaluronidase, it was recently suggested that the GPI-linked mammalian sperm antigen, PH-20, may function as a cell surface hyaluronidase [Gmachl, M., &Expand
FRAP, FLIM, and FRET: Detection and analysis of cellular dynamics on a molecular scale using fluorescence microscopy
The combination of fluorescent‐probe technology plus modern optical microscopes allows investigators to monitor dynamic events in living cells with exquisite temporal and spatial resolution.Expand
