[Infiltration of Th1 and Th17 cells into the L5－S2 spinal cord in CP/CPPS rats and its central sensitization mechanism].

Objective: To explore the central sensitization mechanism of pain in chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS).

Methods: We randomly divided 40 adult male SPF SD rats, aged 3－4 weeks and weighing 250－350 g, into a normal control and a CP/CPPS model group. After modeling, we analyzed the state of infiltration of CD4+T cells into the L5－S2 spinal cord and detected the expression levels of GFAP and CR3 in the spinal cord tissue using flow cytometry, real-time fluorescent quantitative PCR (RT-qPCR) and immunofluorescence staining.

The viral distribution and pathological characteristics of BALB/c mice infected with highly pathogenic Influenza H7N9 virus.

Background: The highly pathogenic Influenza H7N9 virus is believed to cause multiple organ infections. However, there have been few systematic animal experiments demonstrating the virus distribution after H7N9 virus infection. The present study was carried out to investigate the viral distribution and pathological changes in the main organs of mice after experimental infection with highly pathogenic H7N9 virus.

Liver injury in septic mice were suppressed by a camptothecin-bile acid conjugate via inhibiting NF-κB signaling pathway.

Background And Objectives: Sepsis is a life-threatening organ dysfunction syndrome arising from uncontrolled inflammatory responses. Liver injury is a crucial factor for the prognosis of sepsis. Camptothecins (CPTs) have been reported to suppress the inflammatory response induced by sepsis.

Synthesis of Oxazolidin-2-ones from Unsaturated Amines with CO by Using Homogeneous Catalysis.

Carbon dioxide (CO ), a well-known greenhouse gas, is also a nontoxic, readily accessible, and renewable one-carbon (C1) source. However, owing to its thermodynamic stability and kinetic inertness, the efficient utilization of CO is challenging. Much effort has been devoted to achieving efficient and selective organic transformations of CO .

Active immunization with GnRH-tandem-dimer peptide in young male rats reduces serum reproductive hormone concentrations, testicular development and spermatogenesis.

GnRH sterilization vaccines have been developed for various practical and clinical reasons. However, conjugation of GnRH peptide to carrier protein has many drawbacks, hampering the further commercialization of GnRH vaccines. In this study, a new nonconjugated GnRH vaccine, D-Lys6-GnRH-tandem-dimer peptide (TDK), emulsified in Specol adjuvant was investigated for its immunocastration efficacy in young male rats.

[A study on the effect of biomineralization and phosphorylation performed on the titanium implant surfaces].

Objective: To suggest a chemical surface treatment for titanium and to initiate the formation of hydroxycarbonated apatite (HCA) on titanium surface during in vitro bioactivity tests in simulated body fluid (SBF).

Methods: To improve the bone-bonding ability of Ti implants, commercially pure titanium (cpTi) by a simple chemical pre-treatment in orthophosphoric acid (H(3)PO(4)) with different density was activated, and then the phosphorylation specimens were soaked in SBF to investigate the function of biomineralization.

Results: The scanning electron microscope (SEM) photographs showed that the surfaces of the pre-treated samples were characterized by a complex construction, which consisted of a mesh-like morphology matrix (a micro-roughened surface) and an uniform surface with different morphous of titanium dihydrogen orthophosphate [Ti(H(2)PO(4))(3)] crystal.

Effect of interleukin-6 (IL-6) on the vascular smooth muscle contraction in abdominal aorta of rats with streptozotocin-induced diabetes.

Patients with type 1 diabetes are at a risk of hypertension. However, the mechanisms behind the findings are not completely known. The aim of the present study was to investigate involvement of interleukin-6 (IL-6) on the contraction of abdominal aorta in rats with type 1 diabetes.

[Caspase-3 plays a required role in PC12 cell apoptotic death induced by roscovitine].

Roscovitine is a specific inhibitor of cyclin-dependent kinases (cdks) cdc2/cyclin B, cdk2/cyclin A, cdk2/cyclin E and cdk5/p35. The studies on the enzyme inhibitory properties and cellular effects of roscovitine revealed that it arrests cells in G(2)/M and G(1)/S phase, inhibits the proliferation of mammalian cells and induces cell death. However, the characteristics of cell death and exact mechanism by which this cdk inhibitor kills transformed cells are unknown.

Oxytocin microinjected into dorsal motor nucleus of the vagus excites gallbladder motility via NMDA receptor-NO-cGMP pathway.

Our recent study indicated that, in the dorsal motor nucleus of the vagus (DMV), the N-methyl-D-aspartic acid (NMDA) receptor-nitric oxide (NO)-cGMP pathway participated in the regulation of gallbladder motility in rabbits. Oxytocin (OT) is involved as a neurotransmitter in autonomic regulation. The aim of the present experiments is to investigate the effect of OT microinjected into DMV on the gallbladder motility and the involvement of NMDA receptor-NO-cGMP pathway.
