Topological spin-orbit-coupled fermions beyond rotating wave approximation.

The realization of spin-orbit-coupled ultracold gases has driven a wide range of research and is typically based on the rotating wave approximation (RWA). By neglecting the counter-rotating terms, RWA characterizes a single near-resonant spin-orbit (SO) coupling in a two-level system. Here, we propose and experimentally realize a new scheme for achieving a pair of two-dimensional (2D) SO couplings for ultracold fermions beyond RWA.

Unilateral congenital scrotal agenesis with ipsilateral cryptorchidism: A case report.

Background: Congenital scrotal agenesis (CSA) is very rare. There are 11 cases of congenital scrotal agenesis or absence reported in the literature, most of which are bilateral and accompanied by cryptorchidism. Only two cases of which are unilateral scrotal agenesis and not accompanied by cryptorchidism.

Hydrogen Sulfide Targets the Cys320/Cys529 Motif in Kv4.2 to Inhibit the Ito Potassium Channels in Cardiomyocytes and Regularizes Fatal Arrhythmia in Myocardial Infarction.

Aims: The mechanisms underlying numerous biological roles of hydrogen sulfide (H2S) remain largely unknown. We have previously reported an inhibitory role of H2S in the L-type calcium channels in cardiomyocytes. This prompts us to examine the mechanisms underlying the potential regulation of H2S on the ion channels.

A modified single-armed technique for microsurgical vasoepididymostomy.

This study is to evaluate the effectiveness of a modified single-armed suture technique for microsurgical vasoepididymostomy (VE) in patients with epididymal obstructive azoospermia. From September 2011 to December 2011, microsurgical two-suture longitudinal intussusception VEs were performed using our modified single-armed suture technique in 17 men with epididymal obstructive azoospermia at our hospital. Two of these patients underwent repeated VEs after previous failed VEs, and one patient underwent unilateral VE because of an occlusion of the left abdominal vas deferens.

Effects of Leonurine on L-type calcium channel in rat ventricular myocytes.

Leonurine (Leo) is a special alkaloid principle of Herba leonuri that has recently been suggested to improve cardiovascular functions. To date, there is no direct ionic evidence of Leo on regulating calcium channels in the heart. In the present study, we examined the effects of Leo on action potentials and membrane currents recorded from isolated rat ventricular myocytes with the whole-cell patch clamp technique.

Long-term sexual activity status and influencing factors in men after surgery for hypospadias.

The aim of this study was to compare the long-term postoperative status of hypospadiac patients by analysing their sexual psychology, sexual behaviour, sexual function and influencing factors. A total of 130 hypospadiac patients hospitalized between January 1988 and December 2007 were followed up with questionnaires using Zung's Self-rating Depression Scale (SDS), Self-rating Anxiety Scale (SAS), a self-designed sexual function questionnaire and a 5-item version of the International Index of Erectile Function (IIEF-5). The surveys served to evaluate the effects of hypospadias type, number of operations and surgical procedures on sexual psychology, sexual behaviour and sexual function.

[Follow-up study of traumatic macular hole].

Objective: To investigate the natural course and visual outcomes of traumatic macular hole.

Methods: This was a case series observation study. Patients with traumatic macular hole were followed-up for 3 months or longer from August 2004 to December 2007.

[Effects of alprostadil and ulinastatin on inflammatory response and lung injury after cardiopulmonary bypass in pediatric patients with congenital heart diseases].

Objective: To investigate the therapeutic effects of alprostadil (Lipo-PGE1) and Ulinastatin on inflammatory response and lung injury after cardiopulmonary bypass (CPB) in pediatric patients with congenital heart diseases.

Methods: 58 children with congenital heart diseases, including atrial septal defect, ventricular septal defect, and atrioventricular septal defect, scheduled to undergo CPB, aged 4 - 72 months, were randomly divided into 4 groups: alprostadil Group P (n = 15) receiving alprostadil 10 ng/ml added into the prime solution and continuous pump infusion of alprostadil 10 ngxkg(-1)xmin(-1) via central vein until the end of operation, Group U (n = 15) receiving ulinastatin 20 000 U/kg divided into several doses to be added into the prime solution, Group PU (n = 14) receiving alprostadil and ulinastatin according to the above protocols, and Group C (control group, n = 14) receiving normal saline of the equal volume. Electrocardiogram (ECG), heart rate (HR), pulse oxygen saturation (SpO(2)), and mean arterial pressure (MAP) were continuously monitored during operation.

Hydrogen sulphide is an inhibitor of L-type calcium channels and mechanical contraction in rat cardiomyocytes.

Aims: Hydrogen sulphide (H(2)S) is an endogenously generated gaseous transmitter that has recently been suggested to regulate cardiovascular functions. To date, there is no direct evidence for a potential role of H(2)S in regulating calcium channels in the heart. The present study aims to examine the hypothesis that H(2)S is a novel inhibitor of the L-type calcium channel current (I(Ca,L)).

Cellular distribution of GPR14 and the positive inotropic role of urotensin II in the myocardium in adult rat.

Urotensin II is a cyclic neuropeptide recently shown to play a role via its receptor GPR14 in regulating vascular tone in the mammalian cardiovascular system. The existence of GPR14 in rat heart has been validated by ligand binding assay and RT-PCR. In the present study, we investigated the cellular distribution of GPR14 protein in rat heart by using immunohistochemistry and confocal microscopic immunofluorescence double staining with antipeptide polyclonal antibodies against GPR14 and cell type markers for myocytes and endothelial cells.

[Effect of angiotensin II on L-type calcium channel in ischemic ventricular myocytes of the guinea pig].

Using whole cell patch clamp, the effects of angiotensin II (Ang II) on the current L-type calcium channel (I(Ca.L)) were observed in guinea pig isolated ventricular myocytes under simulated ischemia condition, which was realized through hypoxia, glucose deficiency, high lactic acid and acidosis. The results showed that, under the condition of simulated ischemia, the peak of I(Ca.

[Effect of angiotensin II on potassium channels of ischemic ventricular myocytes of the guinea pig].

The experiments were carried out on guinea pig isolated ventricular myocytes by using whole-cell patch clamp. The effects of angiotensin II (Ang II) on potassium ion channels of acute ischemic myocytes were observed. Whole-cell patch clamp recordings showed that physiological potassium current, including delayed rectifier potassium current and inward rectifier potassium current were inhibited under the condition of simulated ischemia, and then further inhibited by treatment with Ang II.
