Abstract Background Most cardiac surgeries are associated with post-sternotomy pain syndrome. Pain causes elevation of blood pressure, heart rate and may be hemodynamic instability, respiratory infections, other postoperative complications. Non-steroidal anti-inflammatory drugs (NSAIDs) among the most commonly used analgesics in surgery. The majority NSAIDs metabolized by cytochrome P-450. mech...

There are major differences between Yorkshire (lean-type) and Wannanhua pig (fat-type) in terms of growth performance and meat quality. Long intergenic noncoding RNAs (lincRNAs) are a class of regulators that are involved in numerous biological processes and widely identified in many species. However, the role of lincRNAs in pig is largely unknown, and the mechanisms by which they affect growth...

Correct gene expression requires tight RNA quality control both at transcriptional and post-transcriptional levels. Using a splicing-defective allele of PASTICCINO2 (PAS2), a gene essential for plant development, we isolated suppressor mutations modifying pas2-1 mRNA profiles and restoring wild-type growth. Three suppressor of pas2 (sop) mutations modified the degradation of mis-spliced pas2-1 ...

The central dogma of biology describes the transfer of biological information from DNA through to protein (Crick, 1970). In the first phase, known as transcription, DNA is converted into a complementary sequence of messenger RNA (mRNA). This mRNA allows the genetic message to be communicated outside of the nucleus, to other areas of the cell, where it is then translated into protein by ribosome...

The RNA exosome is the major 3'-5' RNA degradation machine of eukaryotic cells and participates in processing, surveillance and turnover of both nuclear and cytoplasmic RNA. In both yeast and human, all nuclear functions of the exosome require the RNA helicase MTR4. We show that the Arabidopsis core exosome can associate with two related RNA helicases, AtMTR4 and HEN2. Reciprocal co-immunopreci...

BACKGROUND Plants are recognized as an efficient and inexpensive system to produce valuable recombinant proteins. Two different strategies have been commonly used for the expression of recombinant proteins in plants: transient expression mediated by Agrobacterium; or stable transformation of the plant genome. However, the use of plants as bioreactors still faces two main limitations: low accumu...

Hypoparathyroidism (HPT) is one of the most frequentand severe complications of thyroid surgery. It is caused by intraoperative damage, devascularization or accidental removal of the parathyroid glands (PTGs). The incidence of postoperative HPT is directly proportional to surgery extent and surgeon's experience. After 40 years of experience in thyroid surgery, the first author summarizes the al...

the discovery of rna interference (rnai) in recent years has revolutionized biological and medical research. rnai is the sequence-specific gene silencing triggered by double-stranded rna (dsrna). until a couple of years ago only biologists working with caenorhabditis elegans and plants could use rnai technology to gain insight into gene function……
