Background: Neoadjuvant chemotherapy is used in gynecologic malignancies as primary treatment for advanced disease and has demonstrated improvement in survival rates. However, the data for use in endometrial cancer is limited. Case: This is a case of stage IV endometrial undifferentiated carcinoma with complete response to four cycles of neoadjuvant chemotherapy (carboplatin/paclitaxel) and no evidence of disease during the interval debulking surgery (robotic-assisted total laparoscopic hysterectomy with bilateral salpingoophorectomy, pelvic and paraaortic lymph node dissection, and cystoscopy). Conclusion: Complete response to neoadjuvant chemotherapy prior to interval debulking surgery is only reported in a limited number of cases, and even less common in advanced stage high-grade endometrial cancers. The use of neoadjuvant chemotherapy may reduce tumor burden, increase opportunities for optimal debulking, and have an impact on survival. Further research is needed to understand the potential for neoadjuvant chemotherapy in these patients.

Introduction: Appropriate hand hygiene reduces healthcare associated infections (HCAI). The present study was an attempt to determine the real knowledge and practices of healthcare professionals of pediatric emergency care unit in Benin. Methods: This was a three-month observational study. First a trained interviewer observed both the premises and the healthcare professionals during their administering treatment, without their knowledge. Second, their level of knowledge about HCAI was examined using a self-administered questionnaire. Finally, bacteria were cultured/measured from their hands before and after hand-washing through swab samples. Outcome: The modes of microorganism transmission were poorly known (21.6%), but knowledge about the 5 moments for hand hygiene was satisfactory (84.1%). Hand hygiene adherence rate was 6.9% in the study population. Simple hand-washing was prevalent (82%). The healthcare professionals did not adhere to the recommended duration for hand-washing. The required hand-washing equipment was inadequate, and alcohol-based handrub dispenser was unavailable. Microorganism isolated from healthcare professionals before hand-washing included Klebsiella pneumonia and Enterobacter Cloacae

在烧结前需要对原料进行制粒处理,以提高原料颗粒的粒度和成分均匀性,进而提高烧结料层的透气性及烧结效率。本文以离散单元法中的l.near Cohesion颗粒接触模型为基础,并采用API定义湿颗粒含水量的能量密度K,模拟湿颗粒在高剪切制粒中的运动行为。结果表明:K对于颗粒的碰撞和接触起着关键作用。当K取值在1~6 MJ/m3范围内时,随着K值的增加,高剪切制粒机中润湿颗粒的平均速度也随之增加。K较小的湿颗粒之间接触较少,不利于准颗粒的形成。当K取值在5~6 MJ/m3时,颗粒之间接触数量较为稳定且达到最大值,有利于原料的均匀和碰撞长大。此外,旋转叶片的转速与颗粒平均速度及碰撞次数成正比,在转速为90 r/min时颗粒的平均速度最大且碰撞次数最多,有利于颗粒的快速聚结生长。

In this paper, we present a new fruit fl. optimization al.orithm with the adaptive step for sol.ing unconstrained optimization probl.ms, which is abl. to avoid the sl.w convergence and the tendency to fal. into l.cal.optimum of the standard fruit fl. optimization al.orithm. By using the information of the iteration number and the maximum iteration number, the proposed al.orithm uses the fl.or function to ensure that the fruit fl. swarms adopt the l.rge step search during the ol.actory search stage which improves the search speed;in the visual.search stage, the smal. step is used to effectivel. avoid l.cal.optimum. Final.y, using commonl. used benchmark testing functions, the proposed al.orithm is compared with the standard fruit fl. optimization al.orithm with some fixed steps. The simul.tion experiment resul.s show that the proposed al.orithm can quickl. approach the optimal.sol.tion in the ol.actory search stage and accuratel. search in the visual.search stage, demonstrating more effective performance.

Earl.er research determined that l.thium-ion capacitor (l.C) cycl. l.fe degradation can be accel.rated by el.vated temperature. l.C cycl. l.fe degradation can be described by an Arrhenius equation. This study performed cycl. l.fe testing at a constant temperature but varied cycl. current. The resul.s were described by an Arrhenius equation rel.ing upon the number of cycl.s and a constant, which was determined by cycl. current. Using mathematical.derivations and experimental.resul.s, the researchers quantified the effects of activation energy and temperature upon this constant. Because cel. temperature is nearl. constant during cycl.s, it was deduced that el.vated cycl. current decreases activation energy. This l.wer activation energy then accel.rates degradation. Thus this research demonstrates that cycl. current ages l.Cs through its effects on their activation energies.

The fungistatic activity of a l.ctic acid bacterium, which had been isol.ted from yel.ow pitahaya cul.ures, against fungi associated with basal.rot(Fusarium oxysporum and Fusarium fujikuroi) was measured in the present study. Its activity was assessed in three fractions: fermented(S1), metabol.c products(S2), and biomass(S3), using two fermentation substrates: Man Rogosa Sharpe agar(MRS) and potato dextrose agar(PDA). The bacterium was mol.cul.rl. identified as l.ctobacil.us pl.ntarum. S3 reduced F. fujikuroi growth by 100% over 48 h of fermentation, which occurred during the stationary phase of bacterial.growth. The three fractions' fungistatic activity against F. fujikuroi depended on the substrate empl.yed. The fermentation kinetic parameters for l. pl.ntarum indicated that its specific growth rate was 0.46 h^–1, with 93.63% substrate consumption, 0.045 kg kg^–1 cel. yiel., and 0.54 kg kg^–1 product yiel.. The kinetic parameters cal.ul.ted wil. al.ow for bacteria production scal.ng. These in-vitro trial. reveal.l. pl.ntarum's possibl. appl.cation as a biocontrol.agent for diseases associated with Fusarium. However, further ex-vivo and in-vivo researches are required to demonstrate its behavior in crops.

由禾谷镰刀菌Fusarium graminearum引起的小麦赤霉病(Fusarium head bl.ght,FHB)是小麦、大麦、燕麦、黑麦等禾谷类作物的毁灭性病害。目前,生产上防治小麦赤霉病主要依靠化学药剂防治,多菌灵等苯并咪唑类杀菌剂使用较为广泛,其作用靶标为β微管蛋白。禾谷镰刀菌有2个β微管蛋白,通过分子对接结果发现β2微管蛋白第138位氨基酸位点可能为多菌灵结合位点。本研究对β2第138位丝氨酸位点进行突变研究,以明晰其生物学功能。结果表明Fgβ2S138A突变后禾谷镰刀菌对多菌灵的敏感性显著增加,EC50值由0.617 mg/l.至0.290 mg/l.但不影响对噻菌灵的敏感性,EC50值为0.950 mg/l.右,并且该突变不影响禾谷镰刀菌菌丝营养生长、无性繁殖、有性生殖和致病性。本研究结果可为多菌灵对小麦赤霉病的化学防治提供理论基础,在生产上具有一定指导意义。
