Size-controlled silver nanoparticles synthesized over the range 5–100 nm using the same protocol and their antibacterial efficacy

, 2014
A systematic and detailed study for size-specific antibacterial efficacy of silver nanoparticles (AgNPs) synthesized using a co-reduction approach is presented here. Nucleation and growth kinetics during the synthesis process was precisely controlled and

The newfound relationship between extrachromosomal DNAs and excised signal circles

FEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Inhibitory effect of enterocin GL on Listeria monocytogenes biofilm [PDF]

Zhongguo niangzao
To investigate the inhibitory effect of enterocin GL on Listeria monocytogenes biofilm formation, the sub-lethal concentration and its bactericidal effect were determined, viable cell counts in biofilm, metabolic activity, motility, and extracellular ...

Identification of responders/non-responders to 5-fluorouracil based on individual 50% inhibitory area under the concentration curve of 5-fluorouracil obtained with collagen gel droplet-embedded culture-drug sensitivity test in colorectal cancer

Oncology Letters, 2011
We previously reported the 5-fluorouracil (5-FU) sensitivity of cancer cells obtained from colorectal cancer (CRC) patients using the collagen gel droplet-embedded culture-drug sensitivity test (CD-DST). Multiple drug concentrations and contact durations, and the area under the concentration curve (AUC) and growth inhibition rate (IR) were combined ...

Development of a Spectrophotometric Method for Monitoring Angiotensin-Converting Enzyme in Dairy Products [PDF]

, 2013
The angiotensin-converting enzyme (ACE) regulates the levels of blood pressure through generation of angiotensin-II from angiotensin-I. It is of great importance to have a reliable and yet simple method for a quantitative determination ACE inhibitory ...

Differential in vitro and in vivo effect of barley cysteine and serine protease inhibitors on phytopathogenic microorganisms [PDF]

, 2011
Protease inhibitors from plants have been involved in defence mechanisms against pests and pathogens. Phytocystatins and trypsin/α-amylase inhibitors are two of the best characterized protease inhibitor families in plants.

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Presystemic influences on thirst, salt appetite, and vasopressin secretion in the hypovolemic rat [PDF]

, 2006
Recent studies have shown that when dehydrated rats are given access to water or various concentrations of saline solution, they consume the same volume of fluid in an initial drinking bout (Hoffmann et al., 2006). Furthermore, there was a close relation
