Drosophila Wingless (Wg) is a secreted signaling protein of the Wnt family. Mutations in the wg gene disrupt the patterning of embryonic segments and their adult derivatives. Wg protein has been shown in cell culture to functionally interact with DFz2, a receptor that is structurally related to the tissue polarity protein Frizzled (Fz). However, it has not been determined if DFz2 functions in t...

Two studies examined EEG co-activation (coherence) between the verbal-analytical (T3) and motor planning (Fz) regions during a golf putting task. In Study 1, participants with a strong propensity to consciously monitor and control their movements, determined psychometrically by high scores on a movement specific Reinvestment Scale, displayed more alpha2 T3-Fz co-activation than participants wit...

In this study, the effects of Yb: YAG laser welding parameters on microstructure and mechanical properties AA6061-T4 joints were analysed. Samples without any defects such as porosity, melt pool collapse, hot cracking produced with different parameters. Energetic processing had a significant influence fusion zone (FZ) heat-affected (HAZ) dimensions, in addition to local global properties. The w...

Frizzled (Fz) signaling regulates cell polarity in both vertebrates and invertebrates. In Drosophila, Fz orients the asymmetric division of the sensory organ precursor cell (pI) along the antero-posterior axis of the notum. Planar polarization involves a remodeling of the apical-basal polarity of the pI cell. The Discs-large (Dlg) and Partner of Inscuteable (Pins) proteins accumulate at the ant...

Cells in a variety of developmental contexts sense extracellular cues that are given locally on their surfaces, and subsequently amplify the initial signal to achieve cell polarization. Drosophila wing cells acquire planar polarity along the proximal-distal (P-D) axis, in which the amplification of the presumptive cue involves assembly of a multiprotein complex that spans distal and proximal bo...

UNLABELLED We present a comparative study of thermal donor (TD) center formation mechanisms as a result of carbon ion implantation into float zone (FZ-Si) and Czochralski (Cz-Si) silicon crystals. The kinetics of the TD center formation and transformation of their structure during annealing have been investigated. Also, the TD center formation takes place after additional oxygen implantation in...

Molecules labeled in green and blue play positive and negative roles in Wnt/β-catenin signaling, respectively. Molecules that are labeled in both colors have dual roles. (Top left) Wnt biogenesis. A lipid modification is added to Wnt ligands by Porc in the endoplasmic reticulum (ER). Wnt ligands are glycosylated in the ER and Golgi and require Wls (also known as Evi) to traffic through the Golg...

The efficiency of practical methods for phase retrieval from the intensity distribution in Fresnel (nearfield) images is investigated in the paraxial limit. The aim was to develop a robust and efficient algorithm for phase retrieval from aperiodic objects in the limit where phases may vary continuously by several multiples of 2ð across the sampled field. The equations for Fresnel propagation of...

Cylinders made of tantalum (Ta) and tubes 304 stainless steel (304SS) were successfully joined by laser welding under different offsets. The experimental results indicated that satisfactory weld formations obtained. fusion zone (FZ) was found to consist the Fe–Cr solution Fe2Ta phase. In addition, intermetallic compounds (IMCs) layer generated at Ta/FZ interface. When beam offset − 0.2 mm (0.2 ...
