Receptor-mediated activation of phospholipase C (PLC) which releases diacylglycerol and inositol trisphosphate has been implicated in the action of gonadotropin-releasing hormone (GnRH) on gonadotrophs. Previously we demonstrated that the synthetic diacylglycerol, phorbol 12-myristate 13-acetate (PMA) and PLC mimic the stimulatory effects of GnRH on both luteinizing hormone (LH) glycosylation a...

Human enteric viruses can be present in untreated and inadequately treated drinking water. Molecular methods, such as the reverse transcriptase PCR (RT-PCR), can detect viral genomes in a few hours, but they cannot distinguish between infectious and noninfectious viruses. Since only infectious viruses are a public health concern, methods that not only are rapid but also provide information on t...

Phorbol ester is a strong inducer for both cell cornification and squamous-cell marker SPRR1 gene expression in conducting airway epithelial cells. However, the signaling pathways involved in the regulation of both events have not been completely elucidated. The current study focuses on the common and divergent pathways involved in the induction of these two activities by phorbol-13-myristate-1...

This paper aims to evaluate the performance of synchronous reluctance motors assisted by a permanent magnet (PMa-SynRM) focused on efficiency and torque pulsations. PMa-SynRM shows high power factor, compared induction (IM), although they have greater cost. These machines develop relatively ripple, cogging torque, imbalances. Consequently, electromagnetic is reduced, motor temperature increased...

Phorbol ester (PMA) in concentration 5 and 10 ng ml-1 blocks cytokinesis of the second maturation division in mouse oocytes. Karyokinesis is not impaired and digynic triploid oocytes are obtained which undergo first cleavage division. Effectiveness of blocking cytokinesis is dependent on the timing of exposure of oocytes to PMA action. When oocytes are subjected to PMA at the onset of the secon...

PMA enhanced release of the azurophil granule enzyme, beta-glucuronidase, as well as lysozyme, from cytochalasin B-treated PMN's exposed to either zymosan particles or C5a. PMA was active at nanomolar concentrations, was not toxic to the cells, and was most effective when present for brief durations (0-1 min) before exposure of the cells to the stimuli. Beta-glucuronidase was not released in ...

The development of graphene oxide/rare earth complexes luminescent materials is limited due to the strong quenching ability oxide. However, hybrid with pyromellitic acid (PMA) as ligand not only have better performance, but also stronger luminescence intensity. Herein we tested effect carboxylic structure PMA on intensity materials. Phthalic (PA), Isophthalic (i-PA) and Terephthalic (p-PA) are ...

The premammillary artery (PMA) is a branch of the posterior communicating artery (PCoA). While the PMA is known to originate from the PCoA as demonstrated by most anatomical studies, it originates directly from the internal carotid artery in approximately 1% of patients. Cerebral aneurysms associated with the PMA have rarely been reported. We report an extremely rare case of a ruptured PMA aneu...

Background: Carpal tunnel syndrome (CTS) is a sporadic event with compression of the median nerve (MN). Persistent median artery (PMA) thrombosis is an exceptionally rare cause of CTS. Case report: 38-year-old male presented with acute on subacute right wrist pain with positive Tinel's sign. An ultrasound and computed angiography study confirmed a PMA with thrombosis. The patient was treated wi...

Flexible magnetic materials with robust and controllable perpendicular anisotropy (PMA) are highly desirable for developing flexible high-performance spintronic devices. However, it is still challenge to fabricate PMA films through current techniques of direct deposition on polymers. Here, we report a facile method synthesizing single-crystal freestanding SrRuO3 (SRO) membranes controlled cryst...
