Gigahertz femtosecond laser-by a novel asymmetric one-dimensional photonic crystal saturable absorber device with defect layer.

High repetition frequency (HRF) ultrashort pulse fiber laser has been widely used in laser cold processing. The technical solutions such as short cavity length fiber laser have been proposed to achieve HRF ultrashort pulse output recently. However, the application of material-based saturable absorbers in this field has been astricted due to the low modulation depth, low damage resistance threshold, and high saturation fluence.

Optimal Dexmedetomidine Dose to Prevent Emergence Agitation Under Sevoflurane and Remifentanil Anesthesia During Pediatric Tonsillectomy and Adenoidectomy.

Emergence agitation (EA) is a common pediatric complication after sevoflurane anesthesia that can be prevented with dexmedetomidine. However, an inappropriate dose of dexmedetomidine can cause prolonged sedation and cardiovascular complications. Thus, we evaluated the optimal dose (ED95) of dexmedetomidine for preventing EA with sevoflurane and remifentanil anesthesia after pediatric tonsillectomy and adenoidectomy.

Adrenomedullin Reduces Secondary Injury and Improves Outcome in Rats with Fluid Percussion Brain Injury.

Objective: Traumatic brain injury (TBI) is a devastating neurologic injury and remains a major cause of death in the world. Secondary injury after TBI is associated with long-term disability in patients with TBI. This study evaluated adrenomedullin (AM) on secondary injury and neurologic functional outcome in rats after TBI.

Low dose of dexmedetomidine as an adjuvant to bupivacaine in cesarean surgery provides better intraoperative somato-visceral sensory block characteristics and postoperative analgesia.

Object: In this study, we aimed to investigate the beneficial effects of dexmedetomidine on somato-visceral sensory block characteristcs, postoperative analgesia and stress response of intrathecal bupivacaine administration in women undergoing cesarean section, and to find out which dose is better.

Methods: Sixty parturients with the American Society of Anesthesiologists (ASA) physical status I or II were anesthetized with intrathecal bupivacaine(10mg) alone or in combination with dexmedetomidine (3 μg and 5 μg) to undergo cesarean section. The anesthetic parameters, postoperative analgesia and stress responses were monitored.

Protective effects of propofol against whole cerebral ischemia/reperfusion injury in rats through the inhibition of the apoptosis-inducing factor pathway.

Cerebral ischemia/reperfusion (I/R) injury could cause neural apoptosis that involved the signaling cascades. Cytochrome c release from the mitochondria and the followed activation of caspase 9 and caspase 3 are the important steps. Now, a new mitochondrial protein, apoptosis-inducing factor (AIF), has been shown to have relationship with the caspase-independent apoptotic pathway.

The inhibitory effect of propofol on Kv2.1 potassium channel in rat parietal cortical neurons.

Excessive K(+) efflux via activated voltage-gated K(+) channels can deplete intracellular K(+) and lead to long-lasting membrane depolarization which will promote neuronal apoptosis during ischemia/hypoxia injury. The Kv2.1 potassium channel was the major component of delayed rectifier potassium current (Ik) in pyramidal neurons in cortex and hippocampus.

Inhibition of LN-308 glioma cell proliferation and migration by retinoic acid amide through activation of Akt pathway.

The present study was performed to investigate the effect of retinoic acid amide (RAA) on the expression of integrin α3β1, rate of cell proliferation and migration in p53-deficient glioma cell line, LN-308. The results revealed promotion of integrin α3 expression, reduction in proliferation and migration in RAA treated cells compared to the control LN-308 glioma cells. Promotion of RAA induced integrin α3β1 expression led to the enhancement in cyclin-dependent kinase nuclear localization and activation of Akt pathway.

Effects of propofol and sevoflurane on aquaporin-4 and aquaporin-9 expression in patients performed gliomas resection.

Post-operative cerebral edema is a threat for patients performed gliomas resection. Some studies have shown that general anesthesia drugs, such as, propofol had neuroprotective effect. Aquaporin-4 (AQP4) and Aquaporin-9 (AQP9) play an important role in maintaining brain water homeostasis under various conditions.

Effect of the CYP2D6 gene polymorphism on postoperative analgesia of tramadol in Han nationality nephrectomy patients.

Objective: Tramadol is a synthetic opioid which has analgesic efficacy in the postoperative pain. It is metabolized by polymorphic enzyme cytochrome P450 (CYP2D6). Patients with different CYP2D6 genotypes would have different responses to tramadol in pain relief.

Propofol prevents neuronal mtDNA deletion and cerebral damage due to ischemia/reperfusion injury in rats.

Propofol is a commonly used intravenous anesthetic that has been demonstrated to be neuroprotective against cerebral ischemia-reperfusion (I/R) injury. It remains unclear whether this protective effect has any relationship with the prevention of neuronal mitochondrial deoxyribonucleic acid (mtDNA) deletion. In this study, 81 Wistar rats were randomly divided into three groups (n = 27 each): sham (S group), ischemia/reperfusion (I/R group), or propofol (P group).

N-heterocyclic carbene catalyzed cyclocondensation of α,β-unsaturated carboxylic acids: enantioselective synthesis of pyrrolidinone and dihydropyridinone derivatives.

The catalytic cyclocondensation of in situ activated α,β-unsaturated carboxylic acids was developed. N-heterocyclic carbenes efficiently catalyzed the generation of α,β-unsaturated acyl azolium intermediates from α,β-unsaturated carboxylic acids via in situ generated mixed anhydrides for the enantioselective [3+2] and [3+3] cyclocondensation with α-amino ketones and alkyl(aryl)imines, respectively. The corresponding pyrrolidinones and dihydropyridinones were isolated in good yields with high to excellent enantioselectivities.

Hypercapnic acidosis confers antioxidant and anti-apoptosis effects against ventilator-induced lung injury.

Hypercapnic acidosis may attenuate ventilator-induced lung oxidative stress injury and alveolar cell apoptosis, but the underlying mechanisms are poorly understood. We examined the effects of hypercapnic acidosis on the role of apoptosis signal-regulating kinase 1 (ASK1), which activates the c-Jun N-terminal kinase (JNK) and p38 cascade in both apoptosis and oxidative reactions, in high-pressure ventilation stimulated rat lungs. Rats were ventilated with a peak inspiratory pressure (PIP) of 30 cmH2O for 4 h and randomly given FiCO2 to achieve normocapnia (PaCO2 at 35-45 mm Hg) or hypercapnia (PaCO2 at 80-100 mm Hg); normally ventilated rats with PIP of 15 cmH2O were used as controls.

Diabetic neuropathic pain development in type 2 diabetic mouse model and the prophylactic and therapeutic effects of coenzyme Q10.

Unlabelled: The early onset of type 2 diabetes mellitus (DM), driven by increasing obesity, is associated with peripheral neuropathy. Here, we characterize diabetic neuropathic pain in New Zealand obese diabetic mice (NZO/HILtJ) as a polygenic model of obesity with type 2 diabetes and investigate the role of coenzyme Q10 (CoQ10) in the prevention and treatment of diabetic neuropathic pain. Since the overexpression of mitogen-activated protein kinase (MAPK), nuclear factor-κB proteins (NF-Kb), toll-like receptor 4 (TLR4) and downstream cytokines (such as CCL2, CXCL10) are considered important factors contributing to the development of neuropathic pain, the expression of these factors and the inhibitory effects of CoQ10 were evaluated.

Propofol improved neurobehavioral outcome of cerebral ischemia-reperfusion rats by regulating Bcl-2 and Bax expression.

Propofol is an intravenous anesthetic with neuroprotective effects against cerebral ischemia-reperfusion (I/R) injury. Few studies regarding the neuroprotective and neurobehavioral effects of propofol have been conducted, and the underlying mechanisms are still unclear. Because I/R may result in neuronal apoptosis, the apoptosis regulatory genes B-cell leukemia-2 (Bcl-2) and Bcl-2-associated X protein (Bax) may be involved in the neuroprotective process.

Propofol inhibited the delayed rectifier potassium current (I(k)) via activation of protein kinase C epsilon in rat parietal cortical neurons.

Propofol has been shown to exert neuroprotective effects. Delayed rectifier potassium current (I(K)) was reported to be closely related to neuronal damage. This study was designed to test the effects of propofol on I(K) in rat parietal cortical neurons and the involvement of PKC in this activity.
