BACKGROUND The process of somitogenesis can be divided into three major events: the prepatterning of the mesoderm; the formation of boundaries between the prospective somites; and the cellular differentiation of the somites. Expression and functional studies have demonstrated the involvement of the murine Notch pathway in somitogenesis, although its precise role in this process is not yet well ...

Inverse lithography attempts to synthesize the input mask which leads to the desired output wafer pattern by inverting the forward model from mask to wafer. In this article, we extend our earlier framework for image prewarping to solve the mask design problem for coherent, incoherent, and partially coherent imaging systems. We also discuss the synthesis of three variants of phase shift masks (P...

BACKGROUND AND OBJECTIVES Doppler myocardial imaging (DMI) has been suggested as a method of quantifying inducible ischemia during dobutamine stress echocardiography (DSE). Post-systolic motion (PSM) detected by DMI is related to peri-infarct ischemia during DSE. We hypothesized that PSM during DSE would predict recovery of dysfunctional myocardium after successful percutaneous coronary interve...

to study the effects of biofertilizers in their different levels of nitrogen (n) and phosphorus (p) on yield related parameters of barley (sahra cultivar), a split plot experiment based upon a randomized complete block design of three replications was conducted. main plots consisted of: nitrogen at three levels (0, 50 and 100 kg n ha-1 as urea), while sub plots were: phosphorus at two levels (0...

To date, positive surgical margin (PSM) has been well documented as a risk factor of oncological outcome after radical prostatectomy (RP), and an indicator of adjuvant radiotherapy after RP. Schiavina et al. carried out RP for 837 men with organ-confined or locally-advanced prostate cancer (PCA). A total of 115 (22.8%) of the 504 pT2 men, 86 (32.4%) of the 265 pT3a and 22 (32.4%) of the 68 pT3b...

Indications for oral anticoagulation (OAC) have increased in recent years. OAC requires frequent monitoring of the prothrombin time to keep the intensity within the therapeutic range and to minimise the risk for complications. Patient self-management (PSM) has been found to improve the quality of OAC. The present study aimed to investigate the first 330 patients performing PSM in Switzerland. A...

Vertebrate segmentation is characterized by the periodic formation of epithelial somites from the mesenchymal presomitic mesoderm (PSM). How the rhythmic signaling pulse delivered by the segmentation clock is translated into the periodic morphogenesis of somites remains poorly understood. Here, we focused on the role of paraxial protocadherin (PAPC/Pcdh8) in this process. We showed that in chic...

Rhythmic and sequential subdivision of the elongating vertebrate embryonic body axis into morphological somites is controlled by an oscillating multicellular genetic network termed the segmentation clock. This clock operates in the presomitic mesoderm (PSM), generating dynamic stripe patterns of oscillatory gene-expression across the field of PSM cells. How these spatial patterns, the clock's c...
