The recent identification of multiple dominant mutations in the gene encoding β-catenin in both humans and mice has enabled exploration of the molecular and cellular basis of β-catenin function in cognitive impairment. In humans, β-catenin mutations that cause a spectrum of neurodevelopmental disorders have been identified. We identified de novo β-catenin mutations in patients with intellectual...

We investigated the relationship between oligomerization of CYP3A4 (cytochrome P450 3A4) and its response to ANF (α-naphthoflavone), a prototypical heterotropic activator. The addition of ANF resulted in over a 2-fold increase in the rate of CYP3A4-dependent debenzylation of 7-BFC [7-benzyloxy-4-(trifluoromethyl)coumarin] in HLM (human liver microsomes), but failed to produce activation in BD S...

There is an increasing demand for pulsed all-fibre lasers with gigahertz repetition rates for applications in telecommunications and metrology. The repetition rate of conventional passively mode-locked fibre lasers is fundamentally linked to the laser cavity length and is therefore typically ~10-100 MHz, which is orders of magnitude lower than required. Cascading stimulated Brillouin scattering...

Fast bowling in cricket is an activity that is well recognised as having high injury prevalence and there has been debate regarding the most effective fast bowling technique. The aim of this study was to determine whether two-year coaching interventions conducted in a group of elite young fast bowlers resulted in fast bowling technique alteration. Selected kinematics of the bowling action of 14...

The leucine 211 --> phenylalanine (L211F) and leucine 211 --> tyrosine (L211Y) mutant forms of cytochrome P450 3A4 have been generated by site-directed mutagenesis and expressed functionally in Escherichia coli. Substrate binding affinities (S50 values) for testosterone and 7-benzyloxy-4-trifluoromethylcoumarin (BFC) were similar for the mutants and wild-type CYP3A4 (49 and 21 microM for L211F,...

A DNA segment that is highly conserved in glucokinase (hexokinase IV) and hexokinase I cDNA was used to identify specific cDNAs in a library prepared from rat adipose tissue mRNA. Some of these cDNAs were identified as being hexokinase I cDNA. Others, although similar to both the glucokinase and hexokinase I cDNAs, were unique. Two of these unique cDNAs overlapped and contained an open reading ...

The scintillation statistics of broadband acoustic transmissions are determined as a function of signal bandwidth B, center frequency f(c), and range with experimental data in the New Jersey continental shelf. The received signal intensity is shown to follow the Gamma distribution implying that the central limit theorem has led to a fully saturated field from independent multimodal propagation ...

A red blood cell (RBC) from human exhibited direct electron transfer (DET) activity on a bare indium tin oxide (ITO) electrode. A formal potential of -0.152 V vs. a silver-silver chloride saturated potassium chloride (Ag|AgCl|KCl(satd.)) was estimated for the human RBC (type AB) from a pair of redox peaks at around 0.089 and -0.215 V (vs. Ag|AgCl|KCl(satd.)) on cyclic voltammetric (CV) measurem...

Arid and semiarid environments of Mediterranean countries suffer from scarcity water resources, which limits their agriculture productivity. Using treated wastewater (TWW) is considered an alternative strategy for irrigation purposes in such areas. However, TWW contains substantial levels heavy metals (HMs) contaminants that pollute the environment soil. The aim this study to evaluate phytoreme...

Utilization of treated wastewater (TWW) for agricultural purposes has grown over the past few years because limited available water resources. This study was performed to assess long-term irrigation from Wadi-Musa region on accumulation heavy metals in soil and their uptake translocation various parts olive trees. Fifteen year old trees that had been irrigated with resources since establishment...
