Jenna Gallie et al.
PLoS biology, 13(3), e1002109-e1002109 (2015-03-13)
Phenotype switching is commonly observed in nature. This prevalence has allowed the elucidation of a number of underlying molecular mechanisms. However, little is known about how phenotypic switches arise and function in their early evolutionary stages. The first opportunity to...
Yumiko Mizukoshi et al.
ChemMedChem, 10(4), 736-741 (2015-03-12)
Numerous small organic compounds exist in equilibrium among monomers, soluble oligomers, and insoluble aggregates in aqueous solution. Compound aggregation is a major reason for false positives in drug screening, and even soluble oligomers can interfere with structural and biochemical analyses....

Journal of dental research, 94(2), 344-353 (2014-12-06)
Dental caries is closely associated with the microbial disequilibrium between acidogenic/aciduric pathogens and alkali-generating commensal residents within the dental plaque. Fluoride is a widely used anticaries agent, which promotes tooth hard-tissue remineralization and suppresses bacterial activities. Recent clinical trials have...

Biotechnology and bioengineering, 111(8), 1595-1603 (2014-03-07)
In this work, a proof of concept elastin-like polypeptide-Z domain fusion (ELP-Z) based affinity precipitation process is developed for monoclonal antibody (mAb) purification from industrial harvest feeds. Greater than 99% mAb recoveries are obtained during the initial binding step of...

The Biochemical journal, 462(3), 513-523 (2014-07-02)
Alzheimer's disease is associated with the accumulation of Aβ (amyloid β)-peptides in the brain. Besides their cytotoxic effect on neurons, Aβ-peptides are thought to be responsible for the atherothrombotic complications associated with Alzheimer's disease, which are collectively known as cerebrovascular...

Hormone and metabolic research = Hormon- und Stoffwechselforschung = Hormones et metabolisme, 47(7), 537-543 (2015-01-21)
TLQP-21 is a VGF-derived neuropeptide proposed to be involved in regulation of metabolism. More specifically it has been suggested that TLQP-21 has the ability to enhance glucose stimulated insulin secretion, making it a candidate for treatment of patients with type...
Joseph J Dalluge et al.
Analytical and bioanalytical chemistry, 407(18), 5513-5519 (2015-05-11)
A method has been developed for the direct determination of agmatine in bacterial culture supernatants using isotope dilution ultra performance liquid chromatography (UPLC)-tandem mass spectrometry (UPLC-MS/MS). Agmatine determination in bacterial supernatants is comprised of spiking culture or isolate supernatants with...
Carolina Di Somma et al.
Endocrine, 49(2), 492-502 (2014-11-10)
The aim of the study is to clarify the relationship between adipose tissue dysfunction, metabolic profile and growth hormone (GH)/insulin-like growth factor (IGF)-I secretion in healthy adult subjects. We investigated the metabolic profile in a cohort of 231 consecutive healthy...

Pharmaceutical research, 32(6), 2038-2050 (2014-12-24)
Present study aimed at exploring advantages/disadvantages of amino acid modified trimethylated chitosan in conquering multiple gene delivery obstacles and thus providing comprehensive understandings for improved transfection efficiency. Arginine, cysteine, and histidine modified trimethyl chitosan were synthesized and employed to self-assemble...

Hypertension research : official journal of the Japanese Society of Hypertension, 38(7), 471-477 (2015-03-06)
Renovascular hypertension is characterized by increased renal sympathetic activity, angiotensin II and by endothelial dysfunction. The purpose of this study was to determine the role of renal sympathetic nerve activity (RSNA) in mediating the anti-hypertensive effects of aliskiren (ALSK) and...
Nivaldo Ribeiro Villela et al.
Journal of translational medicine, 12, 232-232 (2014-08-26)
Relative hypovolemia is frequently found in early stages of severe sepsis and septic shock and prompt and aggressive fluid therapy has become standard of care improving tissue perfusion and patient outcome. This paper investigates the role of the nitric oxide...
Jun Yeul Lim et al.
International journal of pharmaceutics, 492(1-2), 127-136 (2015-07-19)
To evaluate the oxidative stability of proteins, a model protein, etanercept, was exposed to oxidative stress conditions using hydrogen peroxide. Various amino acids were also evaluated on their antioxidant effect. Transition temperature (Tm), secondary structural content, hydrodynamic size, and aggregation...
Caroline Nava et al.
Amino acids, 47(12), 2647-2658 (2015-07-29)
Cationic amino acid transporters (CATs) mediate the entry of L-type cationic amino acids (arginine, ornithine and lysine) into the cells including neurons. CAT-3, encoded by the SLC7A3 gene on chromosome X, is one of the three CATs present in the...
N E Paul et al.
Bio-medical materials and engineering, 25(3), 289-297 (2015-09-26)
Adipose tissue engineering is a promising solution for the reconstruction of soft tissue defects. An insufficient neovascularisation within the scaffolds that leads to necrosis and tissue loss is still a major shortcoming of current tissue engineering attempts. Biomaterials, which release...

Journal of ethnopharmacology, 171, 280-286 (2015-06-13)
Asclepias subulata Decne. is a shrub occurring in Sonora-Arizona desert (Mexico-USA). The ethnic groups, Seris and Pimas, use this plant for the treatment of sore eyes, gastrointestinal disorders and cancer. To isolate the compounds responsible for antiproliferative activity of the...
