Long Noncoding RNAs in Human Cancer and Apoptosis.

Genome annotations have uncovered the production of at least one transcript from nearly all loci in the genome at some given time throughout the development. Surprisingly, many of these transcripts do not code for proteins and are relatively long in size, thus called long noncoding RNAs (lncRNAs). Next- and third-generation sequencing technologies have amassed numerous lncRNAs expressed under different phenotypic conditions, yet many remain to be functionally characterized.

Noncoding RNAs in apoptosis: identification and function.

Apoptosis is a vital cellular process that is critical for the maintenance of homeostasis in health and disease. The derailment of apoptotic mechanisms has severe consequences such as abnormal development, cancer, and neurodegenerative diseases. Thus, there exist complex regulatory mechanisms in eukaryotes to preserve the balance between cell growth and cell death.

Transcriptomics Profiling Identifies Cisplatin-Inducible Death Receptor 5 Antisense Long Non-coding RNA as a Modulator of Proliferation and Metastasis in HeLa Cells.

Cisplatin is a well-known cancer chemotherapeutic agent but how extensively long non-coding RNA (lncRNA) expression is modulated by cisplatin is unknown. It is imperative to employ a comprehensive approach to obtain a better account of cisplatin-mediated changes in the expression of lncRNAs. In this study, we used a transcriptomics approach to profile lncRNAs in cisplatin-treated HeLa cells, which resulted in identification of 10,214 differentially expressed lncRNAs, of which 2,500 were antisense lncRNAs.

Transcriptomics Analysis of Circular RNAs Differentially Expressed in Apoptotic HeLa Cells.

Apoptosis is a form of regulated cell death that plays a critical role in survival and developmental homeostasis. There are numerous reports on regulation of apoptosis by protein-coding genes as well as small non-coding RNAs, such as microRNAs. However, there is no comprehensive investigation of circular RNAs (circRNA) that are differentially expressed under apoptotic conditions.

Deep sequencing reveals two Jurkat subpopulations with distinct miRNA profiles during camptothecin-induced apoptosis.

MicroRNAs (miRNAs) are small noncoding RNAs of about 19-25 nt that regulate gene expression posttranscriptionally under various cellular conditions, including apoptosis. The miRNAs involved in modulation of apoptotic events in T cells are partially known. However, heterogeneity associated with cell lines makes it difficult to interpret gene expression signatures, especially in cancer-related cell lines.

Intracytoplasmic Re-localization of miRISC Complexes.

MicroRNAs (miRNAs) are a conserved class of non-coding RNAs of 22 nucleotides that post-transcriptionally regulate gene expression through translational repression and/or mRNA degradation. A great progress has been made regarding miRNA biogenesis and miRNA-mediated gene regulation. Additionally, an ample amount of information exists with respect to the regulation of miRNAs.

Small RNA data set that includes tRNA-derived fragments from Jurkat cells treated with camptothecin.

In this article, we report a small RNA data set obtained from human T cell acute leukemia Jurkat cells, which were treated with the universal apoptotic agent camptothecin. Based on the Annexin-V labeling pattern, we sorted two Jurkat subpopulations in treated cells: one that is sensitive to the drug and the other being relatively more resistant. We report new original data that include the frequency of tRNA-derived fragments (tRF) in drug-sensitive and resistant cells.

Bioactive Sheath/Core nanofibers containing olive leaf extract.

This study aimed at producing silk fibroin (SF)/hyaluronic acid (HA) and olive leaf extract (OLE) nanofibers with sheath/core morphology by coaxial electrospinning method, determining their antimicrobial properties, and examining release profiles of OLE from these coaxial nanofibers. Optimum electrospinning process and solution parameters were determined to obtain uniform and bead-free coaxial nanofibers. Scanning electron microscopy and transmission electron microscopy (TEM) were used to characterize the morphology of the nanofibers.

Pulsatile versus non-pulsatile flow to reduce cognitive decline after coronary artery bypass surgery: A randomized prospective clinical trial.

Background: In this prospective study, we aimed to compare the effect of pulsatile and non-pulsatile flow on the cognitive functions in patients undergoing coronary artery bypass surgery.

Methods: Patients scheduled for their first coronary artery bypass surgery (n = 148) were randomly assigned to the pulsatile flow group (Group A, n = 75) or non-pulsatil group (Group B, n = 73). Cognitive performance was assessed with (MoCA) montreal cognitive assessment test performed by psychologists before coronary artery bypass surgery and 1 month after the operation.

The analgesic effect of 8 and 16 mg lornoxicam administered before shock wave lithotripsy: a randomized, double-blind, controlled study.

Objectives: To evaluate the efficacy of 2 different doses of intravenous lornoxicam for pain relief during shock wave lithotripsy (SWL).

Methods: In this randomized, controlled, double-blind study, 60 ASA I-II patients undergoing SWL were randomly divided into 3 groups. Fifteen minutes before SWL, 4 mL of saline solution was given to the patients in group I, 8 mg lornoxicam in group II, and 16 mg lornoxicam in group III.

Effect of lornoxicam on postoperative analgesia after myomectomy.

Background: In this prospective, randomized study, we evaluate the postoperative analgesic effect of lornoxicam after myomectomy operations.

Material-method: Forty ASA I-II patients scheduled for myomectomy operation were enrolled to this study. Patients were randomly divided into two groups and epidural block was performed with 0,75 % ropivacaine.

Efficacy of lornoxicam in postoperative analgesia after total knee replacement surgery.

In total knee replacement operation, patients have a severe pain in the postoperative period. Because of side effects of opioids, multiple postoperative pain treatment regimens are more suitable in these elderly patients. In this double-blind, randomized, placebo controlled study, the effect of lornoxicam administration (32 mg/48 hour) on morphine consumption and drug-related side effects were investigated in elderly patients undergoing total knee replacement.
