Diazoxide is a putative mitochondrial, ATP-sensitive potassium channel opener that has been implicated in neuroprotection in cerebral ischemia. Administered as pretreatment, diazoxide can attenuate ischemia-related neuronal injury, but little is known about the potential neuroprotective properties of the drug when it is given after the onset of an ischemic insult. In a previous study, we applied diazoxide after imposing chronic cerebral hypoperfusion by means of permanent, bilateral occlusion of the common carotid arteries (2VO) in rats. We observed that ischemia-induced learning impairment assessed in the Morris water maze, and microglial activation visualized by immunocytochemistry, were prevented by diazoxide as determined at 13 weeks after 2VO. However, dimethyl sulfoxide, the organic solvent of diazoxide also prevented memory deficits, without any effect on microglial activity. Therefore, we have repeated our experiments with the use of an inorganic solvent, aqueous NaOH solution in order to clarify the effect of diazoxide independent of dimethyl sulfoxide. The present results demonstrated that diazoxide alone did not improve learning performance, but it prevented microglial activation in the hippocampus 13 weeks after the onset of 2VO. These data provide evidence that post-treatment with diazoxide is not effective in impeding a long-term memory deficiency, but it can attenuate ischemia-induced microglial activation, independently of the solvent used. 相似文献

Comparison of antibody repertoires against Staphylococcus aureus in healthy individuals and in acutely infected patients 总被引:1,自引:0,他引:1

The management of staphylococcal diseases is increasingly difficult with present medical approaches. Preventive and therapeutic vaccination is considered to be a promising alternative; however, little is known about immune correlates of protection and disease susceptibility. To better understand the immune recognition of Staphylococcus aureus by the human host, we studied the antistaphylococcal humoral responses in healthy people in comparison to those of patients with invasive diseases. In a series of enzyme-linked immunosorbent assay analyses performed using 19 recombinant staphylococcal cell surface and secreted proteins, we measured a wide range of antibody levels, finding a pronounced heterogeneity among individuals in both donor groups. The analysis revealed marked differences in the antibody repertoires of healthy individuals with or without S. aureus carriage, as well as in those of patients in the acute phase of infection. Most importantly, we identified antigenic proteins for which specific antibodies were missing or underrepresented in infected patients. In contrast to the well-described transient nature of disease-induced antistaphylococcal immune response, it was demonstrated that high-titer antistaphylococcal antibodies are stable for years in healthy individuals. In addition, we provide evidence obtained on the basis of opsonophagocytic and neutralizing activity in vitro assays that circulating antistaphylococcal serum antibodies in healthy donors are functional. In light of these data we suggest that proper serological analysis comparing the preexisting antibody repertoires of hospitalized patients with different outcomes for nosocomial staphylococcal infections could be extremely useful for the evaluation of candidate vaccine antigens in addition to protection data generated with animal models. 相似文献

Results from recent studies have shown that alpha(1A)-adrenergic receptor (alpha(1A)-AR) antagonists could offer a new alternative in the treatment of preterm delivery. However, members of this group [2-(2,6-dimethoxyphenoxyethyl)aminomethyl-1,4-benzodioxane hydrochloride (WB4101), 5-methylurapidil (5-MU)] are known to influence serotonin (5-hydroxy-tryptamine) (5-HT(1A)) receptors, too. Our objective was to clarify the role of their 5-HT(1A) activities in the uterus relaxant effect. RT-PCR was used to determine mRNA expression of the receptor subtypes in 22 day pregnant rat uteri. Isolated uteri were stimulated by 5-HT or electrical field to investigate the contraction-inhibiting effect and the 5-HT(1A) activity of the alpha(1A) antagonists. Both receptor subtypes are present in rat myometrium. 5-HT induced contractions were inhibited by the alpha(1A) antagonists. Besides shifting the dose-response curve of 5-HT to the right, 5-MU decreased its maximal effect. The alpha(1A) antagonists inhibited electrical field stimulation-induced contractions. 5-HT(1A) blockade increased the maximal effect of 5-MU but did not change that of WB4101. These results suggest that the contraction increase caused by 5-HT is mediated by alpha(1A) receptors. Serotonergic activity of alpha(1) antagonists and especially alpha(1A) antagonists should be investigated as it may alter their efficacy and could interfere with their side-effects. It is proposed that novel alpha(1A) antagonists should be designed with no 5-HT(1A) activity to achieve maximal relaxant effect. 相似文献

British children have the highest levels of ultra-processed food (UPF) consumption in Europe. Schools are posited as a positive setting for impacting dietary intake, but the level of UPFs consumed in schools is currently unknown. This study determined the UPF content of school food in the UK. We conducted a pooled cross-sectional analysis of primary (4–11 years, n = 1895) and secondary schoolchildren (11–18 years, n = 1408) from the UK’s National Diet and Nutrition Survey (2008–2017). Multivariable quantile regression models determined the association between meal-type (school meal or packed lunch) and lunchtime UPF intake (NOVA food classification system). We showed that on average, UPF intake was high in both primary (72.6% total lunch Kcal) and secondary schoolchildren (77.8% total lunch Kcal). Higher UPF intakes were observed in packed lunch consumers, secondary schoolchildren, and those in lower income households. This study highlights the need for a renewed focus on school food. Better guidance and policies that consider levels of industrial processing in food served in schools are needed to ensure the dual benefit of encouraging school meal uptake and equitably improving children’s diets. 相似文献

Objective: To assess the psychological condition of men at the start of the infertility work-up.Methods: Men seeking an infertility evaluation for the first time were recruited. Depression and anxiety symptoms and subjective psychological burden were assessed with the Beck Depression Inventory (BDI), the Spielberger State-Trait Anxiety Inventory (STAI), and a visual analog scale (VAS).Results: Data from 113 patients were analyzed. The mean age of the patients was 33.3 (range: 23–54) years, whereas the mean duration of infertility was 16.3 (range: 0–96) months. Results from the BDI and STAI were 2.24 (SD: ±3.18) and 33.74 (SD: ±8.04). Mild depressive symptoms were found in 4.5% of patients, whereas anxiety reached an abnormal level in 4.9%. There were significant correlations between the results from the BDI score and the duration of infertility (p?=?.024), whereas the STAI and VAS scores showed no similar connection (p?=?.142 and p?=?.261, respectively). Among patients with infertility longer than 2 years, mild depressive symptoms occurred in 23.1%.Conclusion: Among men, the levels of depressive and anxiety symptoms were low at the start of the infertility work-up. Depressive symptom levels increased significantly with the duration of infertility, whereas anxiety levels and VAS scores did not demonstrate a similar correlation. 相似文献
