A number of different researchers have reported a substantial degree of variability in how American English /./ coarticulates with neighboring segments. Acoustic and articulatory data were used to investigate this variability for speakers of ‘‘rhotic’’ American English dialects. Three issues were addressed: ~1! the degree to which the F3 trajectory is affected by segmental context and stress, ~...
OBJECTIVES Based on studies of the extensive tropism of neural stem cells (NSCs) toward malignant brain tumor, we hypothesized that NSCs could also target head and neck squamous cell carcinoma (HNSCC) and could be used as a cellular therapeutic delivery system. METHODS To apply this strategy to the treatment of HNSCC, we used a human NSC line expressing cytosine deaminase (HB1.F3-CD), an enzy...
Signal transducers and activators of transcription (STATs) play key roles in growth factor-mediated intracellular signal transduction. In the present study using a constitutively active STAT5 mutant, we show that STAT5 has pleiotropic functions regulating cell proliferation, differentiation and apoptosis in an IL-3-dependent Ba/F3 cell line. The mutant STAT5 possessed constitutive tyrosine phos...
The effects of Cordyceps sinensis (CS) and its extracted fractions on steroidogenesis in MA-10 cells were determined. Different concentrations of CS and 3 fractions of CS (F1, a water-soluble polysaccharide; F2, a water-soluble protein; and F3, a poorly water-soluble polysaccharide and protein) were added to MA-10 mouse Leydig tumor cells with or without human chorionic gonadotropin (hCG), and ...
The meiotic behavior of pollen mother cells (PMCs) of the F2 and F3 progeny from Triticum timopheevii × hexaploid wild oat was investigated by cytological analysis and sequential C-banding-genomic in situ hybridization (GISH) in the present study. A cytological analysis showed that the chromosome numbers of the F2 and F3 progeny ranged from 28 to 41. A large number of univalents, lagging chromo...
We determine the number of nonzero coefficients (called the Hamming weight) in the polynomial representation of x in F3m = F3[x]/(f), where f ∈ F3[x] is an irreducible trinomial.
X-ray backscatter (XBS) and millimeter wave (mmW) whole body imaging are currently deployed worldwide to screen individuals at security screening checkpoints. The detection of impermissible objects carried by passengers via XBS and mmW screening shares many commonalities with medical radiological screening and diagnosis. A primary objective of this project is to leverage radiological imaging sc...
Latar Belakang: Masalah gizi selama hamil dapat berpengaruh pada kesehatan ibu dan janin. Stunting merupakan kekurangan kronis yang harus segera ditangani. Salah satu produk pangan diberikan anak balita bernilai tinggi terutama kandungan protein kalsium adalah tortilla. Tujuan: Mengetahui formula tempe dengan tepung jagung tortilla chips untuk meningkatkan nilai kalsium. Metode: Penelitian eksp...
F3/contactin (CNTN1) and TAG-1 (CNTN2) are closely related axonal glycoproteins that are differentially regulated during development. In the cerebellar cortex TAG-1 is expressed first as granule cell progenitors differentiate in the premigratory zone of the external germinal layer. However, as these cells begin radial migration, TAG-1 is replaced by F3/contactin. To address the significance of ...
OBJECTIVE Besides than in the control of developmental events, axonal adhesive glycoproteins may be also involved in functions requiring fine organization and connectivity of the nervous tissue. We previously demonstrated morphological alterations and functional cerebellar deficits in transgenic mice (TAG/F3 mice) ectopically expressing the F3/Contactin axonal glycoprotein under the control of ...
