Evolution of replicative DNA polymerases in archaea and their contributions to the eukaryotic replication machinery.

Frontiers in microbiology

Makarova KS, Krupovic M, Koonin EV.
PMID: 25101062
Front Microbiol. 2014 Jul 21;5:354. doi: 10.3389/fmicb.2014.00354. eCollection 2014.

The elaborate eukaryotic DNA replication machinery evolved from the archaeal ancestors that themselves show considerable complexity. Here we discuss the comparative genomic and phylogenetic analysis of the core replication enzymes, the DNA polymerases, in archaea and their relationships with...

Frontiers in plant science

Smýkal P, Vernoud V, Blair MW, Soukup A, Thompson RD.
PMID: 25101104
Front Plant Sci. 2014 Jul 17;5:351. doi: 10.3389/fpls.2014.00351. eCollection 2014.

Timing of seed germination is one of the key steps in plant life cycles. It determines the beginning of plant growth in natural or agricultural ecosystems. In the wild, many seeds exhibit dormancy and will only germinate after exposure...

This study compares two xylanases produced by filamentous fungi such as A. niger and A. flavus using agroindustrial residues as substract and evaluated the effect of these enzymes on cellulose pulp biobleaching process. Wheat bran was the best carbon...

Myocardial ischemia caused by paroxysmal supraventricular tachycardia in a patient with anomalous origin of right coronary artery arising from left sinus of valsalva.

Korean circulation journal

Song SH, Suh SE, Jin SM, Moon JH, Cho YK, Lim SW.
PMID: 23508331
Korean Circ J. 2013 Feb;43(2):123-6. doi: 10.4070/kcj.2013.43.2.123. Epub 2013 Feb 28.

Anomalous origin of a coronary artery is rare and does not generally lead to myocardial infarction and paroxysmal supraventricular tachycardia (PSVT). We report an uncommon case of anomalous origin of the right coronary artery (RCA) originating from the left...

Photoluminescence, chemiluminescence and anodic electrochemiluminescence of hydrazide-modified graphene quantum dots.

Nanoscale

Dong Y, Dai R, Dong T, Chi Y, Chen G.
PMID: 25132204
Nanoscale. 2014 Oct 07;6(19):11240-5. doi: 10.1039/c4nr02539c.

Single-layer graphene quantum dots (SGQDs) were refluxed with hydrazine (N2H4) to prepare hydrazide-modified SGQDs (HM-SGQDs). Compared with SGQDs, partial oxygen-containing groups have been removed from HM-SGQDs. At the same time, a lot of hydrazide groups have been introduced into...

Protective effect of quercetin on chloroquine-induced oxidative stress and hepatotoxicity in mice.

Malaria research and treatment

Kumar Mishra S, Singh P, Rath SK.
PMID: 23607047
Malar Res Treat. 2013;2013:141734. doi: 10.1155/2013/141734. Epub 2013 Mar 27.

The present study was aimed to find out the protective effect of quercetin on hepatotoxicity resulting by commonly used antimalarial drug chloroquine (CQ). Swiss albino mice were administered with different amounts of CQ ranging from human therapeutic equivalent of...

Reprint of: Heparan sulfate as a regulator of endochondral ossification and osteochondroma development.

Matrix biology : journal of the International Society for Matrix Biology

Jochmann K, Bachvarova V, Vortkamp A.
PMID: 24726293
Matrix Biol. 2014 Apr;35:239-47. doi: 10.1016/j.matbio.2014.04.001. Epub 2014 Apr 12.

Most elements of the vertebrate skeleton are formed by endochondral ossification. This process is initiated with mesenchymal cells that condense and differentiate into chondrocytes. These undergo several steps of differentiation from proliferating into hypertrophic chondrocytes, which are subsequently replaced...

The role of a periplasmic gluconolactonase (PpgL)-like protein in Pseudomonas syringae pv. syringae B728a.

World journal of microbiology & biotechnology

Tarighi S, Taheri P.

In Pseudomonas syringae pv. syringae B728a, the Psyr_1712 locus ID encodes a putative protein with a signal peptide and a COG2706 domain of the type present in 3-carboxy-cis,cis-muconate lactonizing enzymes. An amino acid sequence alignment of the P. aeruginosa...

γ-Glutamyl hydrolase modulation significantly influences global and gene-specific DNA methylation and gene expression in human colon and breast cancer cells.

Genes & nutrition

Kim SE, Hinoue T, Kim MS, Sohn KJ, Cho RC, Cole PD, Weisenberger DJ, Laird PW, Kim YI.

Genes Nutr. 2015 Jan;10(1):444. doi: 10.1007/s12263-014-0444-0. Epub 2014 Dec 13.

γ-Glutamyl hydrolase (GGH) plays an important role in folate homeostasis by catalyzing hydrolysis of polyglutamylated folate into monoglutamates. Polyglutamylated folates are better substrates for several enzymes involved in the generation of S-adenosylmethionine, the primary methyl group donor, and hence,...

BACKGROUND: The industrially important yeast Blastobotrys (Arxula) adeninivorans is an asexual hemiascomycete phylogenetically very distant from Saccharomyces cerevisiae. Its unusual metabolic flexibility allows it to use a wide range of carbon and nitrogen sources, while being thermotolerant, xerotolerant and...
