GROWTH ASPECTS, YIELD AND RUSTS INFECTION FOR SOM WHEAT CULTIVARS (Triticum aestivum L.) AS AFFECTED BY SOWING DATES [PDF]

open access: yesJournal of Plant Production, 2000
A two-year field experiment (1997 and 1998) was carried out to study rusts infection and growth aspects for wheat cultivars (Giza 157 and 161, Gemmiza 1 and Sakha 8 and 69) as affected by sowing dates (5 and 20 November in addition to 5 December). Sowing

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Marine yeast isolation and industrial application [PDF]

open access: yes, 2014
Over the last century, terrestrial yeasts have been widely used in various industries, such as baking, brewing, wine, bioethanol and pharmaceutical protein production. However, only little attention has been given to marine yeasts. Recent research showed

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

open access: yesFEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Tetracycline-Regulated Expression of VEGF-A in Beta Cells Induces Angiogenesis: Improvement of Engraftment following Transplantation

open access: yesCell Transplantation, 2006
Early revascularization of pancreatic islet cells after transplantation is crucial for engraftment, and it has been suggested that vascular endothelial growth factor-A (VEGF-A) plays a significant role in this process.

Principals' Perceptions of Isolation and Contributing Factors: A Mixed Methods Analysis [PDF]

open access: yes
Principals’ perceived isolation has been empirically associated with factors such as lower self-efficacy, job dissatisfaction, and burnout and a strong predictor of a principal's intentions to leave the profession.

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Fault detection and isolation of actuator failures for a large transport aircraft [PDF]

open access: yes, 2007
- We consider the problem of designing residual generators with least dynamical orders to solve actuator fault detection and isolation problems for a Boeing 747-100/200 aircraft. The main result of our analysis is the proof of feasibility of the complete
