The Effect of Removing Synthetic Amino Acids from the Poultry Ration on the Final Live and Dressed Weight of Birds from the Sheepdrove Organic Farm Organic Silvo-Poultry System [PDF]

, 2004
Organic standards and aspirations are moving towards the removal of synthetic amino acids from organic poultry rations. Sheepdrove Organic Farm has already removed synthetic amino acids from the rations fed to its chickens.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Free amino acids in a cave beetle \u3cem\u3eDarlingtonea kentuckensis\u3c/em\u3e Valentine (Coleoptera: Carabidae) [PDF]

, 1974
Free amino acids of Darlingtonea kentuckensis were investigated by two-dimensional, thin-layer chromatography on Silica Gel G. Thirteen amino acids which could be identifìed (alanine, glutamic acid, glycine, histidine, isoleucine and/or leucine, lysine ...

Asparagine promotes cancer cell proliferation through use as an amino acid exchange factor. [PDF]

, 2016
Cellular amino acid uptake is critical for mTOR complex 1 (mTORC1) activation and cell proliferation. However, the regulation of amino acid uptake is not well-understood.

Plasmodium falciparum gametogenesis essential protein 1 (GEP1) is a transmission‐blocking target

FEBS Letters, EarlyView.
This study shows Plasmodium falciparum GEP1 is vital for activating sexual stages of malarial parasites even independently of a mosquito factor. Knockout parasites completely fail gamete formation even when a phosphodiesterase inhibitor is added. Two single‐nucleotide polymorphisms (V241L and S263P) are found in 12%–20% of field samples.

Proteins and peptides as antigen candidates for the immunodiagnosis of hepatitis D

Amino Acids
Designing innovative, accurate, universal, and accessible diagnostic tests is mandatory to improve screening, prevention, and management of hepatitis D (HD), especially in endemic areas with poor infrastructure and restricted access to public health care.

Linked dimers of the AAA+ ATPase Msp1 reveal energetic demands and mechanistic plasticity for substrate extraction from lipid bilayers

FEBS Letters, EarlyView.
Cells must clear mislocalized or faulty proteins from membranes to survive. The AAA+ ATPase Msp1 performs this task, but dissecting how its six subunits work together is challenging. We engineered linked dimers with varied numbers of functional subunits to reveal how Msp1 subunits cooperate and use energy to extract proteins from the lipid bilayer ...

CacyBP/SIP - RPL6 interaction: potential influence on ribosome function

Amino Acids
Previously, we have shown that CacyBP/SIP interacts with NPM1, a protein involved in ribosome biogenesis. In this work, we extended our previous studies to look for the potential impact of CacyBP/SIP on ribosome biogenesis and/or function.

Local softness, softness dipole and polarizabilities of functional groups: application to the side chains of the twenty amino acids

, 2009
The values of molecular polarizabilities and softnesses of the twenty amino acids were computed ab initio (MP2). By using the iterative Hirshfeld scheme to partition the molecular electronic properties, we demonstrate that the values of the softness of ...

Efficient and Mild Microwave-Assisted Stepwise Functionalization of Naphthalenediimide with α-Amino Acids [PDF]

, 2006
Microwave dielectric heating proved to be an efficient method for the one-pot and stepwise syntheses of symmetrical and unsymmetrical naphthalenediimide derivatives of α-amino acids.
