2Calcium phosphate cements for bone engineering and their biological properties显示文摘Calcium phosphate cements(CPCs) are frequently used to repair bone defects. Since their discovery in the 1980 s, extensive research has been conducted to improve their properties, and emerging evidence supports their increased application in bone tissue engineering. Much effort has been made to enhance the biological performance of CPCs, including their biocompatibility, osteoconductivity, osteoinductivity, biodegradability,bioactivity, and interactions with cells. This review article focuses on the major recent developments in CPCs,including 3 D printing, injectability, stem cell delivery, growth factor and drug delivery, and prevascularization of CPC scaffolds via co-culture and tri-culture techniques to enhance angiogenesis and osteogenesis.Hockin HK Xu Ping Wang Lin Wang Chongyun Bao Qianming Chen Michael D Weir Laurence C Chow Liang Zhao Xuedong Zhou Mark A Reynolds 2017Bone Research2017,5,4:14
3超重与男性生殖能力研究进展:睡眠呼吸暂停,一个新领域显示文摘肥胖会对男性生殖产生负面影响,主要是因为肥胖与低睾酮水平和促性腺激素改变有关。男性肥胖已经被发现与男性生育力下降有关,但由于影响的性质和程度不同,肥胖与精子参数相关性的数据存在争议。一些新研究领域的出现,如遗传多态性和睡眠呼吸暂停,将有助于解释研究结果的差异性。已经发现睡眠紊乱与男性睾酮生成的变化和性腺功能低下有关,也可能与勃起功能障碍有关。睡眠紊乱与不育和精子参数的关系还有待研究。忠有性腺功能低下和不育的男性应该进行睡眠呼吸暂停症的筛查。对肥胖和睡眠呼吸暂停的治疗可以改善睾酮水平和勃起功能。Ahmad O Hammoud Douglas T Carrell Mark Gibson C Matthew Peterson A Wayne Meikle 2012Asian Journal of Andrology2012,14,1:11
4Influence of dissolved organic matter character on mercury incorporation by planktonic organisms: An experimental study using oligotrophic water from Patagonian lakes显示文摘Ligands present in dissolved organic matter(DOM) form complexes with inorganic divalent mercury(Hg2+) afecting its bioavailability in pelagic food webs. This investigation addresses the influence of a natural gradient of DOM present in Patagonian lakes on the bioaccumulation of Hg2+(the prevailing mercury species in the water column of these lakes) by the algae Cryptomonas erosa and the zooplankters Brachionus calyciflorus and Boeckella antiqua. Hg2+accumulation was studied through laboratory experiments using natural water of four oligotrophic Patagonian lakes amended with197Hg2+. The bioavailability of Hg2+was afected by the concentration and character of DOM. The entrance of Hg2+into pelagic food webs occurs mostly through passive and active accumulation. The incorporation of Hg2+by Cryptomonas, up to 27% of the Hg2+amended, was found to be rapid and dominated by passive adsorption,and was greatest when low molecular weight compounds with protein-like or small phenolic signatures prevailed in the DOM.Conversely, high molecular weight compounds with a humic or fulvic signature kept Hg2+in the dissolved phase, resulting in the lowest Hg2+accumulation in this algae. In Brachionus and Boeckella the direct incorporation of Hg from the aqueous phase was up to3% of the Hg2+amended. The dietary incorporation of Hg2+by Boeckella exceeded the direct absorption of this metal in natural water,and was remarkably similar to the Hg2+adsorbed in their prey. Overall, DOM concentration and character afected the adsorption of Hg2+by algae through competitive binding, while the incorporation of Hg2+into the zooplankton was dominated by trophic or dietary transfer.María C.Diéguez Claudia P.Queimalios Sergio Ribeiro Guevara Mark Marvin-DiPasquale Carolina Soto Crdenas María A.Arribre 2013Journal of Environmental Sciences2013,25,10:6
5Reuse of liver grafts following the brain death of the initial recipient显示文摘AIM: To determine if there is a reasonable prospect of success of a re-use liver transplantation.METHODS: We systematically searched for reports of liver graft re-use using electronic searches of PubMed and Web of Knowledge. We performed hand searches of references lists of articles reporting re-use of grafts.RESULTS: A systematic review of the literature reveals 28 liver transplantations using previously transplanted grafts. First and second recipients ranged in age from 4 to 72 years and 29 to 62 years respectively. Liver disease in the first recipient was varied including 5(18%) patients with fulminant liver failure who died subsequently of cerebral edema. The second transplanta-tion was performed after a median interval of 5 d(one day-13 years). Viral hepatitis was present in 3(11%) of the initial recipients and in 8(29%) of final recipients. Hepatocellular carcinoma was present in 6(21%) of the final recipients. Early survival after the final transplantation was 93%, whereas long-term survival was 78% with a mean follow-up of 23.3(3-120) mo.CONCLUSION: Outcomes of transplantation using previously transplanted grafts in this select population are similar to those seen with conventional grafts.Hideaki Tanaka Vivian C McAlister Mark A Levstik Cameron N Ghent Paul J Marotta Douglas Quan William J Wall 2014World Journal of Hepatology2014,6,6:3

9Percutaneous transluminal angioplasty balloons for endoscopic ultrasound-guided pancreatic duct interventions显示文摘BACKGROUND Endoscopic ultrasound(EUS)-guided main pancreatic duct(PD)access may be used when conventional endoscopic retrograde cholangiopancreatography(ERCP)techniques fail.The use of a percutaneous transluminal angioplasty balloon(PTAB),originally developed for vascular interventions,can be used to facilitate transmural(e.g.,transgastric)PD access and to dilate high-grade pancreatic strictures.AIM To describe the technique,efficacy,and safety of PTABs for EUS-guided PD interventions.METHODS Patients who underwent EUS with use of a PTAB from March 2011 to August 2021 were retrospectively identified from a tertiary care medical center supply database.PTABs included 3-4 French angioplasty catheters with 3-4 mm balloons designed to use over a 0.018-inch guidewire.The primary outcome was technical success.Secondary outcomes included incidence of adverse events(AEs)and need for early reintervention.RESULTS A total of 23 patients were identified(48%female,mean age 55.8 years).Chronic pancreatitis was the underlying etiology in 13(56.5%)patients,surgically altered anatomy(SAA)with stricture in 7(30.4%),and SAA with post-operative leak in 3(13.0%).Technical success was achieved in 20(87%)cases.Overall AE rate was 26%(n=6).All AEs were mild and included 1 pancreatic duct leak,2 cases of post-procedure pancreatitis,and 3 admissions for post-procedural pain.No patients required early re-intervention.CONCLUSION EUS-guided use of PTABs for PD access and/or stricture management is feasible with an acceptable safety profile and can be considered in patients when conventional ERCP cannulation fails.Jad P AbiMansour Barham K Abu Dayyeh Michael J Levy Andrew C Storm John A Martin Bret T Petersen Ryan J Law Mark D Topazian Vinay Chandrasekhara 2022World Journal of Gastrointestinal Endoscopy2022,14,8:2

12Exogenous cytokinin application to Actinidia chinensis var. deliciosa ‘Hayward’ fruit promotes fruit expansion through water uptake显示文摘Exogenous application of a cytokinin-like compound forchlorfenuron(CPPU)can promote fruit growth,although often at the expense of dry matter(DM),an important indicator of fruit quality.Actinidia chinensis var.deliciosa‘Hayward’fruit are very responsive to CPPU treatments,but the mechanism underlying the significant fruit weight increase and associated decrease in DM is unclear.In this study,we hypothesised that CPPU-enhanced growth increases fruit carbohydrate demand,but limited carbohydrate supply resulted in decreased fruit DM.During fruit development,CPPU effects on physical parameters,metabolites,osmotic pressure and transcriptional changes were assessed under conditions of both standard and a high carbohydrate supply.We showed that CPPU increased fruit fresh weight but the dramatic DM decrease was not carbohydrate limited.Enhanced glucose and fructose concentrations contributed to an increase in soluble carbohydrate osmotic pressure,which was correlated with increased water accumulation in CPPU-treated fruit and up-regulation of water channel aquaporin gene PIP2.4 at 49 days after anthesis.Transcipt analysis suggested that the molecular mechanism contributing to increased glucose and fructose concentrations was altered by carbohydrate supply.At standard carbohydrate supply,the early glucose increase in CPPU fruit was associated with reduced starch synthesis and increased starch degradation.When carbohydrate supply was high,the early glucose increase in CPPU fruit was associated with a general decrease in starch synthesis but up-regulation of vacuolar invertase and fructokinase genes.We conclude that CPPU affected fruit expansion by increasing the osmotically-driven water uptake and its effect was not carbohydrate supply-limited.Simona Nardozza Helen L Boldingh Mark W Wohlers Andrew P Gleave Zhiwei Luo Guglielmo Costa Elspeth A MacRae Michael J Clearwater Annette C Richardson 2017Horticulture Research2017,4,1:2
