Objectives: To examine goal process cognition as a mediator of the relationship between self-determined motivational ratings and strenuous exercise participation. Design: Cross-Sectional Survey. Methods: University students (N 1⁄4 535) identified their most important exercise goal and rated this goal according to the nine goal process dimensions of the Goal Systems Assessment Battery (GSAB; [Ka...
We report the synthesis and characterization of N,N-bis[(7-dimethylamino)phenothiazin-5-ium-3-yl]-4,4-ethylenedipiperidine diiodide (3), consisting of two photosensitizing phenothiazinium rings attached to a central ethylenedipiperidine linker. At all time points (10, 30, 60 min) and all wavelengths (676, 700, 710 nm) tested, photocleavage of pUC19 plasmid DNA (22 degrees C and pH 7.0) was mark...
با توجه به تاثیرات درماندگی مالی بر روی گروه های مختلف ذینفع، همواره ارائه الگوهای پیش بینی ورشکستگی یکی از جذاب ترین حوزه ها در تحقیقات مالی بوده است. پژوهش حاضر به مطالعه ی پیش بینی ورشکستگی مالی شرکتها در بورس اوراق بهادار تهران به وسیله ی مدل تحلیل پوششی داده ها می پردازد. تحلیل پوششی داده ها یک روش ناپارامتریک برای ارزیابی کارایی واحدهای عملیاتی است، اما در این پژوهش کاربردی متفاوت از تحلی...
Colorectal cancer (CRC) is one of most common cancers and causes of cancer-associated mortality worldwide, due to its recurrence, metastasis and therapy resistance. Cancer stem cells (CSC) have been demonstrated to be vital for tumor initiation and recurrence. microRNAs may act as an oncogenes or tumor suppressors in numerous cancers. The present study demonstrated that microRNA-141 (miR‑141) w...
Nuclear factor I-A1 (NF1-A1) can bind to the TTGGC motif in the rat regucalcin gene promoter region. This study was undertaken to determine whether NF1-A1 is involved in the enhancement of the rat regucalcin gene promoter activity using the -710/+18 LUC construct (wild-type) or -710/+18 LUC construct with the deletion of -523/-435 including the TTGGC motif (mutant) in cloned normal rat kidney p...
BACKGROUND Nutrients, hormones and growth factors in dairy foods may stimulate growth hormone (GH), insulin-like growth factor I (IGF-I), and raise the ratio of IGF-I to its binding protein, IGFBP-3. We conducted pilot studies in Mongolia and Massachusetts to test the extent to which milk intake raised somatotropic hormone concentrations in prepubertal children. METHODS In Ulaanbaatar, we com...
A single-round polymerase chain reaction (PCR) diagnostic assay was developed from a small subunit ribosomal DNA (SSU rDNA) gene sequence to detect the myxozoan parasite Kudoa neurophila, the causative agent of myxozoan disease in the hatchery reared marine finfish, striped trumpeter Latris lineata (Forster). The assay was developed for use as a disease control management tool in a hatchery sys...

MicroRNAs (miRNAs) are 21 to 24 nucleotide, non-coding RNA molecules that post-transcriptionally regulate the expression of target genes. Ultraviolet B (UVB) radiation has been shown to inhibit phosphatase and tensin homolog deleted on chromosome 10 (PTEN) expression in HaCaT cells through an unknown mechanism. In this study, we investigated whether miR-141 can regulate UVB exposure-mediated in...
Viruses rely on the host translation machinery to complete their life cycles. Picornaviruses use an internal ribosome entry site to initiate cap-independent protein translation and in parallel host cap-dependent translation is shut off. This process is thought to occur primarily via cleavage of host translation initiation factors eIF4GI and eIF4GII by viral proteases. Here we describe another m...
