Those who have worked in the field of quantitative polymerase chain reaction (PCR) since the early 1990s have accepted many of the tedious aspects of the early assays as routine. Difficulties associated with early quantitative PCR techniques included: (i) ensuring that the PCR was within the linear range of amplification (that portion where the PCR signal is directly proportional to the input c...

MicroRNAs play an important role in the etiology and progression of many diseases, including intervertebral disc degeneration (IVDD). The miRNA miR-129-5P regulates autophagy in various cancers, but its role in human nucleus pulposus (NP) cells is unclear. The present study investigated whether miR-129-5p regulates the expression of Beclin-1 which is known to induce autophagy in NP cells by eva...

This study demonstrates the effects of miRNA-10b on medulloblastoma proliferation through transcriptional induction of the anti-apoptotic protein BCL2. Using a cancer specific miRNA-array, high expression of miRNA-10b in medulloblastoma cell lines compared to a normal cerebellar control was shown, and this was confirmed with real time PCR (RT-PCR). Two medulloblastoma cell lines (DAOY and UW228...

abstract: herpes simplex encephalitis (hse) is a life threatening outcome of herpes simplex virus (hsv) infection of the central nervous system (cns). hsv accounts for 2-5 percent of all cases of encephalitis. one third of cases occur in those younger than 20 years old and one half in those older than 50 years old. clinical diagnosis is recommended in the encephalopathic, febrile patients with ...

Aberrant expression of microRNA-34a (miR-34a) has been reported to be involved in the tumorigenesis and progression of various classes of malignancies. However, its role in hepatocellular carcinoma (HCC) has not been completely clarified. In the current study, we have investigated the clinical significance and the in vitro contribution of miR-34a on biological functions of human HCCs. miR-34a e...

We investigated the mechanisms by which microRNA (miR)-182 promotes apoptosis and inhibits proliferation in human osteosarcoma (OS) cells. Levels of miR-182 and Homeobox A9 (HOXA9) expression were compared between human OS and normal cells. Subjects were divided into OS and normal groups. We analyzed the target relationship of miR-182 and Homeobox A9 (HOXA9). Cells were then assigned into blank...

conclusions in patients with abdominal or pelvic masses and a history of previous abdominal surgery, the possibility of gossypiboma should be kept in mind. case presentation we report two patients (the first patient was 50 years old, with a history of an appendectomy three years ago in another city; the second patient was 52 years old, with a history of a cesarean section 25 years ago in anothe...

ing at the University of Arizona. Saadatmanesh developed the material, called CarbonWrap, about six years ago and now sells it through CarbonWrap Solutions. The polymer is made of woven filaments of glass, carbon and Kevlar, which are placed in a resin matrix. Its tensile strength—the force required to pull it apart—is about 200 tons per square inch, 10 times stronger than steel. The fiber cost...

Azobenzene-3,3'-dicarboxylic acid exists in photoisomerizable (E) and (Z)-forms. Deprotonation of the carboxylic acid groups from the (E)-form occurs simultaneously, whereas in the (Z)-form it occurs in a stepwise fashion. The mono anionic form of the (Z)-isomer acts as a glycosidase mimic that proceeds through a general acid-general base catalytic mechanism. This is the first example of a phot...
