AIM:To evaluate the performance of the specific French Vittel "pre-Hospital(pH) resuscitation" criteria in selecting poly.rauma patients during the pre-hospital stage and its potential to increase the positive predictive value(ppV) of pre-hospital trauma ***: This was a monocentric prospective cohort study.of injured adults transported by.emergency.medi-cal service to a trauma center. patients who met any.of the field trauma triage criteria were considered "triage positive". Hospital data was statistically.linked to prehospital records. The primary.outcome of defining a "major trauma patient" was Injury.Severity.Score(ISS) > 16. RESULTS: There were a total of 200 injured patients evaluated over a 2 y.ars period who met at least 1 triage criterion. The number of false positives was 64 patients(ISS ppV was 68%. The sensitivity.and the negative predictive value could not be evaluated in this study.since it only.included patients with positive Vittel criteria. The criterion of "pH resuscitation" was present for 64 patients(32%),but 10 of them had an ISS y.significant in correlation with the severity.of the trauma in univariate analy.is(OR = 7.2; p = 0.005; 95%CI: 1.6-31.6). However,despite this correlation the overall ppV was not significantly.increased by.the use of the criterion "pH resuscitation"(68% vs 67.8%).CONCLUSION: The criterion of "pre-hospital resuscitation" was statistically.significant with the severity.of the trauma,but did not increase the ppV. The use of "prehospital resuscitation" criterion could be re-considered if these results are confirmed by.larger studies.

purpose: To evaluate the effect of balanced hy.ocaloric diet therapy.on the anthropometric and basic metabolic indicators in obese women with infertility. Methods: The follow up interventional clinical study.included 23 infertile women in reproductive age with grade I gluteofemoral obesity. All patients have prescribed a balanced hy.ocaloric diet (1200 kcal/day., underwent exercise and behavioral therapy. Before and after 12-month treatment, an anthropometric study.was conducted, determining the level of metabolic and hormonal indicators. Results: The total final number of study.participants was 20 patients. A decrease in body.weight was achieved in 87% of patients from 4 to 24 kg, on the average, by.10.58 ± 5.70 kg, there was also a decrease in BMI from 32.53 ± 1.40 to 28.55 ± 2.50 kg/m2 (p 0.001). The decrease in body.weight was accompanied by.a statistically.significant decrease in leptin levels (p 0.001), E1 (p = 0.049), E2 (p = 0.032), fasting glucose (p 0.001), HOMA-IR (p = 0.002), cholesterol (p p = 0.004), LDL-C (p = 0.001), atherogenic index of plasma (p progesterone levels (p = 0.030). Ovulatory.menstrual cy.les were resumed in all women (p = 0.007) and pregnancy.occurred within a y.ar in 1 patient. Conclusion: The implementation of a hy.ocaloric diet for 12 months in infertile women with first-degree obesity.helps to normalize metabolic and hormonal indicators, reduces body.weight and restores ovulatory.menstrual cy.le in all patients.

研究了南瓜籽烘干和烘炒工艺对南瓜籽油中活性成分的影响。结果表明:烘干南瓜籽油维生素E、类胡萝卜素、总酚含量显著高于烘炒南瓜籽油(p<0.05)。木犀草素是南瓜籽油中的主要酚类物质。同一热处理工艺下,维生素E、总酚随温度的升高而增加,类胡萝卜素随温度的升高而减少,温度对酚类物质含量没有显著影响。采用烘干南瓜籽榨取的南瓜籽油营养价值更高,功能性更强。

propolis is a natural substance made from resins collected from trees and plants, and which bees combine with pollen, wax, and their own enzy.es. It has a complex chemical composition that varies with the harvest season, vegetation ty.e, bee species, and geographical region. Thanks to its components, it has valuable biological properties such as antifungal, antibacterial, anticancer, antiviral, and immunomodulatory.activity. For this study. a sample of propolis harvested in April 2019 was used, which came from a bee native to Mexico (Plebeia frontalis) in whose geographical environment there are seven other native species. Canine distemper virus is an RNA virus that causes a sy.temic infection with high fatality.rates in guests without protective immunity. In this work, the antiviral effect of Plebeia frontalis propolis on canine distemper virus was tested, administering it one hour before and simultaneously.to infection. The antiviral effect was evaluated by.determining cellular viability.with the MTT assay. The results obtained show that this propolis has a statistically.significant antiviral effect on both treatments, although it is slightly.better when applied one hour before viral infection, so we can recommend it as an antiviral treatment in both domestic animals and human beings. There are currently.few studies of the antiviral effect of propolis, this being the first study.of a melliponium propolis in veterinary.medicine.

Transmission electron microscopy.and surface- and bulk-sensitive spectroscopic methods were used to study.the morphology.and the electronic structure of a hy.rid organic-inorganic sy.tem composed of gold nanoparticles （Np＇s） which were distributed in an organic matrix. Au atoms deposited onto a copper phthalocy.nine （Cupc） surface diffuse into the organic matrix and self-assemble in well defined Np＇s with metallic properties. No formation of a continuous metallic Au film on top of the Cupc film is observed up to nominal coverages as large as 130 A.

众多植物多糖中,阿拉伯半乳聚糖对嗜黏蛋白阿克曼菌(Akkermansia muciniphila,Akk)模式菌株(DSM22959)的促生长效果最佳。为进一步探究阿拉伯半乳聚糖对Akk代谢物的影响,本研究将阿拉伯半乳聚糖作为部分碳源对Akk进行体外发酵培养,确定了阿拉伯半乳聚糖的补充量以便于Akk发酵液样本的后续分析,采用高分辨非靶向代谢组学技术对Akk发酵液样本中的差异代谢物进行了检测及分析。研究发现,菌株发酵液中呈显著变化(VIp>1,p<0.05)的差异代谢物共85种,差异代谢通路共32条。结果表明,阿拉伯半乳聚糖可通过影响新陈代谢通路、氨基酸生物合成通路、2-氧代羧酸代谢通路、ABC转运蛋白通路等代谢途径,促使Akk产生更多具有特殊功效的代谢产物如次黄嘌呤、罗汉松酯酚、丙酸等,分别具有减肥、抗癌及降血压的潜能。本研究结果为未来将阿拉伯半乳聚糖作为Akk的益生元或与Akk联合作为合生元提供了理论依据。
