We have isolated a strongly mitogenic, type B transforming growth factor (BTGF) released by SnyderTheilen feline sarcoma virus-transformed rat embryo (FeSV-Fre) cells that induces phenotypic transformation of normal NRK cells when they are concomitantly stimulated by analogues of epidermal growth factor (EGF). Molecule filtration chromatography separates BTGF from an EGF-like TGF (eTGF) which i...

OBJECTIVE To compare the risk of ectopic pregnancy (EP) after embryo transfer on day 3(D3-ET) and day 5(D5-ET). DESIGN Meta-analysis. PATIENTS Women with pregnancy resulting from in vitro undergoing in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). RESULT(S) Twenty-two studies were identified through research conducted using the PubMed, Embase, and Cochrane database...

This paper describes how to response of oscilloscopes, especially at low fre MHz to 1 GHz. The method uses the phas standard mixer calibrated by three-mixer reference phase. We describe basic principles obtained using a balanced mixer and a real-tim GHz BW).

Polydimethylsiloxane (PDMS) elastomer is used in a wide range of biomaterial applications including microfluidics, cell culture substrates, flexible electronics, and medical devices. However, it has proved challenging to 3D print PDMS in complex structures due to its low elastic modulus and need for support during the printing process. Here we demonstrate the 3D printing of hydrophobic PDMS pre...

4-Hydroxyphenylacetate 3-hydroxylase (HpaB and HpaC) of Escherichia coli W has been reported as a two-component flavin adenine dinucleotide (FAD)-dependent monooxygenase that attacks a broad spectrum of phenolic compounds. However, the function of each component in catalysis is unclear. The large component (HpaB) was demonstrated here to be a reduced FAD (FADH(2))-utilizing monooxygenase. When ...

Altered regulation of 5-HT1A receptors is implicated in mood disorders such as anxiety and major depression. To provide insight into its transcriptional regulation, we previously identified a novel DNA element [14 bp 5'-repressor element (FRE)] of the 5-HT1A receptor gene that mediates repression in neuronal and non-neuronal cells (Ou et al., 2000). We have now cloned a novel DNA binding protei...

Exploiting the physics of nanoelectronic devices is a major lead for implementing compact, fast, and energy efficient artificial intelligence. In this work, we propose an original road in direction, where assemblies spintronic resonators used as synapses can classify an-alogue radio-frequency signals directly without digitalization. The convert ra-dio-frequency input into direct voltages throug...

a case who was suffering from abdominal pain and chronic diarrhea refered to isfahan health training and research center, institute of public health. current treatments for chronic diarrhea incloding a traial of gluten fre diet were performed but these were not effective because he was infected by dicrocoelium dentriticum. then he was cured with parasitic treatment.
