| 1 | Gut dysfunction in Parkinson's disease显示文摘Early involvement of gut is observed in Parkinson's disease(PD) and symptoms such as constipation may precede motor symptoms. α-Synuclein pathology is extensively evident in the gut and appears to follow a rostrocaudal gradient. The gut may act as the starting point of PD pathology with spread toward the central nervous system. This spread of the synuclein pathology raises the possibility of prion-like propagation in PD pathogenesis. Recently, the role of gut microbiota in PD pathogenesis has received attention and some phenotypic correlation has also been shown. The extensive involvement of the gut in PD even in its early stages has led to the evaluation of enteric α-synuclein as a possible biomarker of early PD. The clinical manifestations of gastrointestinal dysfunction in PD include malnutrition, oral and dental disorders, sialorrhea, dysphagia, gastroparesis, constipation, and defecatory dysfunction. These conditions are quite distressing for the patients and require relevant investigations and adequate management. Treatment usually involves both pharmacological and nonpharmacological measures. One important aspect of gut dysfunction is its contribution to the clinical fluctuations in PD. Dysphagia and gastroparesis lead to inadequate absorption of oral anti-PD medications. These lead to response fluctuations, particularly delayed-on and no-on, and there is significant relationship between levodopa pharmacokinetics and gastric emptying in patients with PD. Therefore, in such cases, alternative routes of administration or drug delivery systems may be required. | Adreesh Mukherjee Atanu Biswas Shyamal Kumar Das | 2016 | World Journal of Gastroenterology2016，22，25： | 26 |

| 3 | 单人进行大鼠胃旁路手术的学习曲线显示文摘目的 分析单人进行大鼠胃旁路手术模型建立的学习曲线.方法 2013年6月至2013年9月,分别由两组(A组和B组)实验人员各完成60只大鼠的胃旁路手术,并按每组手术先后次序再分别分为Ⅰ、Ⅱ、Ⅲ3个时间段,每时间段内大鼠20只.先比较A组与B组间手术时间和术后存活率的差异,再比较两组内各时间段之间手术时间和术后存活率之间的差异.结果 A组与B组手术时间和术后存活率的比较,差异均无统计学意义(均P>0.05).但AⅡ和AⅢ组手术时间较AⅠ组显著缩短[(78.5±2.5)和(73.3±1.4)比(127.3±3.2) min,均P<0.01],大鼠存活率明显提高[75%(15/20)和85%(17/20)比30%(6/20),均P<0.05].B组内三个时间段也得出了与A组相似的结果.结论 单人进行大鼠胃旁路手术学习曲线约为20只,迈过学习曲线后可获得较为高效而稳定的建模成功率. | 任亦星 Ali Tavakkoli Pal Atanu 李敬东 孙骥 李强 | 2014 | 中华胃肠外科杂志2014，17，7： | 2 |
| 4 | Enhanced photoluminescence quantum yield of MAPbBr3 nanocrystals by passivation using graphene显示文摘Diminishing surface defect states in perovskite nancx^rystals is a highly challenging subject for enhancing optoelectronic device performance.We synthesized organic/inorganic lead-halide perovskite MAPbBr3(MA=methylammonium)clusters comprising nanocrystals with diameters ranging between 20 and 30 nm and characterized an enhanced photoluminescence(PL)quantum yield(as much as^7 times)by encapsulating the MAPbBr3 with graphene(Gr).The optical properties of MAPbBr3 and Gr/MAPbBr3 were investigated by temperature-dependent micro-PL and time-resolved PL measurements.Density functional theory calculations show that the surface defect states in MAPbBr3 are removed and the optical band gap is reduced by a 0.15 eV by encapsulation with graphene due to partial restoration of lattice distortions. | Youngsin Park Atanu Jana Chang Woo Myung Taeseung Yoon Geungsik Lee Claudius C.Kocher Guanhua Ying Vitaly Osokin Robert A.Taylor Kwang S.Kim | 2020 | Nano Research2020，13，4： | 2 |
