Optical phase conjugation (OPC) is an all-optical signal processing technique for mitigating fiber nonlinearity and promising building cost-efficient networks with few optic-electric-optic conversions long amplification spacing. In lumped amplified systems, OPC has a little mitigation efficiency nonlinear distortion induced by cross-phase modulation (XPM) due to the asymmetry of power chromatic...

OPC-14523 (OPC; [1-[3-[4-(3-Chlorophenyl)-1-piperazinyl]propyl]-5-methoxy-3,4-dihydro-2-quinolinone monomethanesulfonate)] is a novel compound with high affinity for and 5-HT1A receptors as well as for the 5-HT transporter. OPC has previously been shown to produce antidepressant-like effects in animal models of depression. This project set out to determine the effect of OPC on serotonergic neur...

Na(+),K(+)-ATPase and cell survival were investigated in a cellular model of ischemia-reperfusion (I/R)-induced injury and protection by ouabain-induced preconditioning (OPC). Rat neonatal cardiac myocytes were subjected to 30 min of substrate and coverslip-induced ischemia followed by 30 min of simulated reperfusion. This significantly compromised cell viability as documented by lactate dehydr...

BACKGROUND Extracapsular spread (ECS) in cervical lymph node metastases from head and neck squamous cell carcinoma (SCC) is regarded as an adverse prognostic factor and is often used to select patients who may benefit from adjuvant therapy. The prognostic value of ECS was evaluated for patients with oropharyngeal SCC (OPC; with known p16/human papillomavirus [HPV] status) and for patients with ...

Levels of circulating cytokines are elevated in inflammatory diseases. Previously, it was shown that interleukin (IL-)17A, in synergism with 1,25-dihydroxyvitamin D3 [1,25(OH)2D3] and tumor necrosis factor α (TNFα), induces the release of granulocyte-macrophage colony-stimulating factor (GM-CSF) by murine osteoblasts in vitro. In this study, we further analyzed the effects of GM-CSF on osteocla...

BACKGROUND In human immunodeficiency virus (HIV)-infected patients, fluconazole prophylaxis is associated with reductions in the rate of fungal infection. However, concerns exist with regard to the use of fluconazole prophylaxis and the risk of development of fluconazole treatment-refractory infections. METHODS We performed a randomized, open-label trial that compared oral fluconazole given c...

If L is a lattice with the interpolation property whose cardinality is a strong limit cardinal of uncountable cofinality, then some finite power L has an antichain of size κ. Hence there are no infinite opc lattices. However, the existence of strongly amorphous sets implies (in ZF) the existence of infinite opc lattices.

El objetivo del presente estudio fue caracterizar 10 variedades de quinua (Chenopodium quinoa Willd.) y una variedad quelite cenizo album L.), diferente color planta producción materia seca en la parte aérea, por su contenido nitratos oxalatos completa (NPC, OPC), hojas (NH, OH) tallos (NT, OT), presencia alcaloides las etapas botón floral floración condiciones riego temporal o secano Montecill...

To examine the involvement of vasopressin and dehydration in the regulation of aquaporin-2 (AQP2) expression in rat kidney, we investigated the effects of treatment for 60 h with the specific V2-receptor antagonist OPC-31260 (OPC), alone and in conjunction with dehydration for the last 12 h. Changes in AQP2 protein and mRNA expression in kidney inner medulla were determined by Western and North...

Background. The incidence of oropharyngeal squamous cell carcinoma (OPC) is on the rise. This is now known to be largely due to infection with human papillomavirus (HPV), the most common sexually transmitted disease in the world. Patients with human immunodeficiency virus (HIV) are particularly susceptible to all HPV-associated malignancies including OPC, but very little is known to guide their...
