Background: Micro RNAs (miRNAs) are small, noncoding RNA molecules. They can function as either oncogenes or tumor suppressor genes. Single nucleotide polymorphisms (SNP) present in the pre-miRNA region could affect the processing of miRNA and thus alter mature miRNA expression. The studies done so far had shown conflicting results regarding association of two common polymorphisms i.e.hsa-miR-1...

Correlations of the 142 Nd/ 144 Nd ratio with the Sm/Nd ratio in some meteorites have been previously explained by the-decay of long-lived 146 Sm. In order to account for these observations, a necessary production ratio for 146 Sm/ 144 Sm in the-process of 0.1{0.7 was deduced. The ratio (148 Gd(,n) 147 Gd)/(148 Gd(,) 144 Sm), which plays the dominant role in the production of 146 Sm/ 144 Sm, ha...

UNLABELLED This study was performed to investigate the usefulness of a general-purpose medium-energy (ME) collimator for the accurate localization of the sentinel lymph node (SLN) in breast cancer patients. METHODS We compared phantom images and lymphoscintigraphy images obtained under different conditions for a patient with breast cancer. Comparisons were performed between 2 cameras, between...

Mevalonate kinase serine/threonine residues have been implicated in substrate binding and inherited metabolic disease. Alignment of >20 mevalonate kinase sequences indicates that Ser-145, Ser-146, Ser-201, and Thr-243 are the only invariant residues with alcohol side chains. These residues have been individually mutated to alanine. Structural integrity of the mutants has been demonstrated by bi...

A 2-yr study was conducted to evaluate the effects of a high-energy creep feed, preweaning zeranol implants and breed type on calf and cow performance. Two hundred calves sired by Brahman and Romana Red bulls out of Angus and Angus x Brown Swiss reciprocal crossbred (F1) dams were stratified by breed type and sex to three creep treatments: no creep feed (NC); long-term creep (LC), creep-fed fro...

The ability to locate nerve injury and ensuing neuroinflammation would have tremendous clinical value for improving both the diagnosis and subsequent management of patients suffering from pain, weakness, and other neurologic phenomena associated with peripheral nerve injury. Although several non-invasive techniques exist for assessing the clinical manifestations and morphological aspects of ner...

Environmental waters are an important reservoir for Vibrio cholerae, and effective surveillance of the pathogen can help to warn of and prevent infection with this potentially fatal pathogen. An immunofluorescent-aggregation (IFAG) assay to detect V. cholerae O1 and O139 was established and evaluated with estuarine water samples. The practical application of this assay was compared with the con...

In vitro derivation of germ cells from different stem cells sources has been challenging in the treatment of male infertility. MicroRNAs (miRNAs) have an essential role in gene expression at post-transcriptional level. The aim of this research was to find more about miRNA-17 and miRNA-146 expression during differentiation of spermatogonial stem cell like cells (SSC like cells) from mouse bone m...
