| 2 | 离子通道、磷酸化和哺乳动物精子获能显示文摘有性生殖动物需要精子和卵子之间进行精心协调的交流才能产生新的个体。精子获能是发生在女性生殖系统中的生殖细胞成熟的一个复杂现象,让精子能够和卵子联结并融合,是哺乳动物生育的必要条件。精子获能过程包括了质膜重组、离子渗透调节、胆固醇减少和许多蛋白质磷酸化状态的变化。研究精子离子通道的新工具能用更好的时空解析度将细胞内的离子变化和蛋白图像化,这些工具正在一步步阐明离子运输和磷酸化状态中的一系列调节是如何引起获能的。最近的证据表明有两条平行的通路调节引起获能的磷酸化发生。其中一条通路要求蛋白激酶A活化,另一条通路需要丝氨酸/苏氨酸磷酸酶失活。本文综述了精子获能所要求的离子运输参与和磷酸化信号处理。理解导致生育的分子机制,对于人们应对男性不育率升高、开发安全的以雄性配子为基础的避孕药、通过辅助生殖策略保持生物多样性都至关重要。 | Pablo E Visconti Dario Krapf Jose Luis de la Vega-Beltran Juan Jose Acevedo Alberto Darszon | 2011 | Asian Journal of Andrology2011，13，3： | 19 |
| 3 | Failed medial patellofemoral ligament reconstruction:Causes and surgical strategies显示文摘Patel ar instability is a common clinical problem encountered by orthopedic surgeons specializing in the knee. For patients with chronic lateral patellar instability, the standard surgical approach is to stabilize the patella through a medial patellofemoral ligament(MPFL) reconstruction. Foreseeably, an increasing number of revision surgeries of the reconstructed MPFL will be seen in upcoming years. In this paper, the causes of failed MPFL reconstruction are analyzed:(1) incorrect surgical indication or inappropriate surgical technique/patient selection;(2) a technical error; and(3) an incorrect assessment of the concomitant risk factors for instability. An understanding of the anatomy and biomechanics of the MPFL and cautiousness with the imaging techniques while favoring clinical over radiological findings and the use of common sense to determine the adequate surgical technique for each particular case, are critical to minimizing MPFL surgery failure. Additionally, our approach to dealing with failure after primary MPFL reconstruction is also presented. | Vicente Sanchis-Alfonso Erik Montesinos-Berry Cristina Ramirez-Fuentes Joan Leal-Blanquet Pablo E Gelber Joan Carles Monllau | 2017 | World Journal of Orthopedics2017，8，2： | 14 |
| 4 | Naringenin prevents experimental liver fibrosis by blocking TGFβ-Smad3 and JNK-Smad3 pathways显示文摘AIM To study the molecular mechanisms involved in the hepatoprotective effects of naringenin(NAR)on carbon tetrachloride(CCl4)-induced liver fibrosis.METHODS Thirty-two male Wistar rats(120-150 g)were randomly divided into four groups:(1)a control group(n=8)that received 0.7%carboxy methyl-cellulose(NAR vehicle)1 m L/daily p.o.;(2)a CCl4 group(n=8)that received 400 mg of CCl4/kg body weight i.p.3 times a week for 8 wk;(3)a CCl4+NAR(n=8)group that received 400 mg of CCl4/kg body weight i.p.3times a week for 8 wk and 100 mg of NAR/kg body weight daily for 8 wk p.o.;and(4)an NAR group(n=8)that received 100 mg of NAR/kg body weight daily for 8 wk p.o.After the experimental period,animals were sacrificed under ketamine and xylazine anesthesia.Liver damage markers such as alanine aminotransferase(ALT),alkaline phosphatase(AP),γ-glutamyl transpeptidase(γ-GTP),reduced glutathione(GSH),glycogen content,lipid peroxidation(LPO)and collagen content were measured.The enzymatic activity of glutathione peroxidase(GPx)was assessed.Liver histopathology was performed utilizing Masson’s trichrome and hematoxylin-eosin stains.Zymography assays for MMP-9 and MMP-2 were carried out.Hepatic TGF-β,α-SMA,CTGF,Col-I,MMP-13,NF-κB,IL-1,IL-10,Smad7,Smad3,p Smad3 and p JNK proteins were detected via western blot.RESULTS NAR administration prevented increases in ALT,AP,γ-GTP,and GPx enzymatic activity;depletion of GSH and glycogen;and increases in LPO and collagen produced by chronic CCl4 intoxication(P<0.05).Liver histopathology showed a decrease in collagen deposition when rats received NAR in addition to CCl4.Although zymography assays showed that CCl4 produced an increase in MMP-9 and MMP-2gelatinase activity;interestingly,NAR administration was associated with normal MMP-9 and MMP-2 activity(P<0.05).The anti-inflammatory,antinecrotic and antifibrotic effects of NAR may be attributed to its ability to prevent NF-κB activation and the subsequent production of IL-1 and IL-10(P<0.05).NAR completely prevented the increase in TGF-β,α-SMA,CTGF,Col-1,and MMP-13 proteins compared with the CCl4-treated group(P<0.05).NAR prevented Smad3phosphorylation in the linker region by JNK since this flavonoid blocked this kinase(P<0.05).CONCLUSION NAR prevents CCl4 induced liver inflammation,necrosis and fibrosis,due to its antioxidant capacity as a free radical inhibitor and by inhibiting the NF-κB,TGF-β-Smad3 and JNK-Smad3 pathways. | Erika Hernández-Aquino Natanael Zarco Sael Casas-Grajales Erika Ramos-Tovar Rosa E Flores-Beltrán Jonathan Arauz Mineko Shibayama Liliana Favari Víctor Tsutsumi José Segovia Pablo Muriel | 2017 | World Journal of Gastroenterology2017，23，24： | 10 |
| 5 | Silvicultural alternatives to conventional even-aged forest man-agement-what limits global adoption?显示文摘Background: The development of forestry as a scientific and management discipline over the last two centuries has mainly emphasized intensive management operations focused on increased commodity production, mostly wood. This 'conventional' forest management approach has typically favored production of even-aged, single-species stands. While alternative management regimes have generally received less attention, this has been changing over the last three decades, especially in countries with developed economies. Reasons for this change include a combination of new information and concerns about the ecological consequences of intensive forestry practices and a willingness on the part of many forest owners and society to embrace a wider set of management objectives. Alternative silvicultural approaches are characterized by a set of fundamental principles, including avoidance of clearcutting, an emphasis on structural diversity and small-scale variability, deployment of mixed species with natural regeneration,and avoidance of intensive site-preparation methods.Methods: Our compilation of the authors' experiences and perspectives from various parts of the world aims to initiate a larger discussion concerning the constraints to and the potential of adopting alternative silvicultural practices.Results: The results suggest that a wider adoption of alternative silvicultural practices is currently hindered by a suite of ecological, economic, logistical, informational, cultural, and historical constraints. Individual contexts display their own unique combinations and relative significance of these constraints, and accordingly, targeted efforts, such as regulations and incentives, may help to overcome specific challenges.Conclusions: In a broader context, we propose that less emphases on strict applications of principles and on stand structures might provide additional flexibility and facilitate the adoption of alternative silvicultural regimes in a broader set of circumstances. At the same time, the acceptance of alternative silvicultural systems as the 'preferred or default mode of management' wil necessitate and benefit from the continued development of the scientific basis and valuation of a variety of ecosystem goods and services. This publication is aimed to further the discussion in this context. | Klaus J Puettmann Scott McG Wilson Susan C Baker Pablo J Donoso Lars Dr?ssler Girma Amente Brian D Harvey Thomas Knoke Yuanchang Lu Susanna Nocentini Francis E Putz Toshiya Yoshida Jürgen Bauhus | 2015 | Forest Ecosystems2015，2，2： | 4 |
| 6 | Addition of statins to the standard treatment in patients with cirrhosis:Safety and efficacy显示文摘This review summarizes the safety and efficacy of statins in patients with cirrhosis.Due to concerns about the safety of statins in patients with impaired liver function,they have recently been investigated as a potential treatment option in cirrhosis.The most clinically significant adverse event is statin-related myopathy,and this may be related to the high serum statin concentrations in the setting of severely impaired liver function.Rhabdomyolysis is the most serious and potentially life-threatening manifestation.It has recently been demonstrated that the recommended dose of simvastatin in patients with decompensated cirrhosis would be 20 mg/d because higher values,such as 40 mg/d,are associated with many adverse events,especially muscle injury.Likewise,simvastatin should not be administered to patients with Model for End-stage Liver Disease score>12 and/or Child-Pugh class C because of the high risk of severe muscle injury.Due to the pleiotropic effects,the focus on statins has shifted from being considered harmful to something useful.Through these effects,statins could prevent liver-related morbidity and mortality in cirrhotic patients.Observational studies in large populations of patients with cirrhosis have shown that treatment with statins to decrease high cholesterol levels was associated with a reduced risk of hepatic decompensation,hepatocellular carcinoma development and death.The few randomized controlled trials in patients with cirrhosis and portal hypertension showed that statins lower portal pressure,quite likely through a reduction in hepatic resistance.Another large randomized controlled trial in patients with variceal bleeding showed that simvastatin in addition to standard of care did not prevent rebleeding but improved survival rate.Despite these encouraging outcomes,the quality of the evidence regarding the use of statins is low or very low due to the observational characteristics of most of the studies involved.Therefore,it is advisable to perform further randomized controlled trials on a large series of patients with hard clinical endpoints,using different statin types and varying doses.The objectives would be to prevent liver-related morbidity and mortality rather than treating cirrhosis complications to take additional information that makes it possible to add statins to the standard of care of these patients. | Alberto E Muñoz Florencia D Pollarsky Mónica Marino Mariano Cartier Horacio Vázquez Pablo Salgado Gustavo Romero | 2021 | World Journal of Gastroenterology2021，27，28： | 4 |
| 7 | 联合钢厂采用无碳排放的ENERGIRON直接还原方案减少温室气体的排放显示文摘在基于高炉冶炼的联合企业中,始终有一些过剩的焦炉煤气、转炉煤气和高炉炉顶煤气,通常这些煤气用于电厂发电。另一种替代方法是使用这些现有的能源气体生产直接还原铁(DRI),将其作为金属化炉料加入高炉,提高粗钢产量,以减少化石燃料单耗。优化利用主要的化石燃料可以显著降低吨钢CO2排放量。采用传统的BF-BOF流程,即使在优化工艺流程的基础上,吨钢CO2排放量也有1.7~1.8t左右。而用产自天然气、焦炉煤气和高炉炉顶煤气的DRI作为金属化炉料加入高炉或电炉,却可显著降低CO2排放量。 | Pablo E Duarte Jorge Becerra 熊林(译) 张友平(校) | 2012 | 世界钢铁2012，12，3： | 3 |
