Effect of AlSi coating on laser spot welding of press hardened steel and process improvement with annular stirring

open access: yesMaterials & Design, 2020
Laser spot welding method was employed to fabricate AlSi coated press-hardened steel (PHS) joints in overlapped configuration. Al and Si segregate at the notch root of a laser spot weld of AlSi coated PHS resulting in pre-mature cracking and weakening ...

Lack of effect of the human GM-CSF analog E21R on the survival of primary human acute myeloid leukemia cells [PDF]

open access: yes, 2004
The granulocyte-macrophage colony-stimulating factor (GM-CSF) analog E21R binds to the GM-CSF receptor complex with low affinity and acts as a competitive antagonist.

Invisible but not inaccessible—Revealing transient oligomers formed by intrinsically disordered proteins with solution NMR and complementary methods

open access: yesFEBS Letters, EarlyView.
Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.

Emerging Markets for GM Foods: A Study of Consumer's Willingness to Pay in India [PDF]

open access: yes
A random utility approach is used to estimate logit equations which indicate what factors affect the likelihood of consumption of non-GM and GM foods, and, whether or not consumers are willing to pay a premium for non-GM/GM foods.

DNA ligase LigE increases bacterial transformation with damaged extracellular DNA

open access: yesFEBS Letters, EarlyView.
The DNA ligase LigE from the naturally competent Gram‐negative bacterium Neisseria gonorrhoaea increases transformation with cut extracellular DNA. This process is ATP‐dependent and relies on the catalytic activity of LigE; it also requires that LigE contains an intact periplasmic localisation sequence, indicating that ligE functions in the periplasm ...

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

open access: yesMolecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Engraftment of adult hematopoietic stem and progenitor cells in a novel model of humanized mice

open access: yesiScience
Summary: Pre-clinical use of humanized mice transplanted with CD34+ hematopoietic stem and progenitor cells (HSPCs) is limited by insufficient engraftment with adult non-mobilized HSPCs.

Evidence of price premiums for non-GM grains in world markets [PDF]

open access: yes
World markets for a number of grains (soybeans, corn, canola and cottonseed) have become differentiated into GM, certified non-GM and organic segments, which has created opportunities and challenges for grain market participants.
