1Primary identifications and palynological observations of Perilla in China显示文摘Unresolved controversies concerning the classification of the monotypic genus Perilla L.have hindered the complete understanding and subsequent sustainable use of these vital food,oil,and medicinal plants to their full potential.In the present study,we used scanning electron microscopy to obtain palynological evidence from 21 samples of Perilla plants from seven provinces in China as a potential further attribute for classification.The findings showed that pollen grains from plants of 11 samples were oblate,whereas those of the other 10 were suboblate;there were no prolate pollen grains observed.Pollen grains from all samples had diverse exine ornamentations.Based on whether they had continuous tecta on the ornamentations,the pollen grains from the 21 samples were classified into two categories:(i) 14 with irregular reticulates;and (ii) seven with continuous tecta with no perforations.None of the samples was bireticulate.The ornamentation pattern and size of pollen grains jointly provided evidence that it is appropriate for use in classifying the genus Perilla into five varieties of one species.Furthermore,by comparison,it is concluded that the shapes and exine ornamentations of Perilla are unique among those of the seven genera already investigated in the subfamily Lamioideae.Using these pollen features,Perilla can be easily distinguished from the two other subtribes (Menthinae Briq.and Thyminae Briq.) in the same tribe,supporting the view that Perilla and the other four related genera can be classified into one subtribe (Perillinae).Yan HU Li-Wei SUN Mokgolodi Neo C.

4Quantitative Study on Nonmetallic Inclusion Particles in Steels by Automatic Image Analysis With Extreme Values Method显示文摘The presence of nonmetallic inclusion particles which appear during steelmaking process is harmful to the properties of steels,which is mainly as a function of some aspects such as size,volume fraction,shape,and distribution of these particles.The automatic image analysis technique is one of the most important tools for the quantitative determination of these parameters.The classical Student approach and the Extreme Values Method(EVM) were used for the inclusion size and shape determination and the evaluation of distance between the inclusion particles.The results thus obtained indicated that there were significant differences in the characteristics of the inclusion particles in the analyzed products.Both methods achieved results with some differences,indicating that EVM could be used as a faster and more reliable statistical methodology.Cássio Barbosa José Brant de Campos Jneo Lopes do Nascimento Iêda Maria Vieira Caminha 2009Journal of Iron and Steel Research(International)2009,16,4:7
5Outcomes of Roux-en-Y gastric bypass and laparoscopic adjustable gastric banding显示文摘AIM:To evaluate weight loss and surgical outcomes of Roux-en-Y gastric bypass(RYGB)and laparoscopic adjustable gastric band(LAGB).METHODS:Data relating to changes in body mass index(BMI)and procedural complications after RYGB(1995-2009;n=609;116M:493F;42.4±0.4 years)or LAGB(2004-2009;n=686;131M:555F;37.2±0.4years)were extracted from prospective databases.RESULTS:Pre-operative BMI was higher in RYGB than LAGB patients(46.8±7.1 kg/m2vs 40.4±4.2 kg/m2,P<001);more patients with BMI<35 kg/m2underwent LAGB than RYGB(17.1%vs 4.1%,P<0.0001).BMI decrease was greater after RYGB.There were direct relationships between weight loss and pre-operative BMI(P<0.001).Although there was no difference in weight loss between genders during the first 3-year post-surgery,male LAGB patients had greater BMI reduction than females(-8.2±4.3 kg/m2vs-3.9±1.9kg/m2,P=0.02).Peri-operative complications occurred more frequently following RYGB than LAGB(8.0%vs0.5%,P<0.001);majority related to wound infection.LAGB had more long-term complications requiring corrective procedures than RYGB(8.9%vs 2.1%,P<0.001).Conversion to RYGB resulted in greater BMI reduction(-9.5±3.8 kg/m2)compared to removal and replacement of the band(-6.0±3.0 kg/m2).Twelve months post-surgery,fasting glucose,total cholesterol and low density lipoprotein levels were significantly lower with the magnitude of reduction greater in RYGB patients.CONCLUSION:RYGB produces substantially greater weight loss than LAGB.Whilst peri-operative complications are greater after RYGB,long-term complication rate is higher following LAGB.Nam Q Nguyen Philip Game Justin Bessell Tamara L Debreceni Melissa Neo Carly M Burgstad Pennie Taylor Gary A Wittert 2013World Journal of Gastroenterology2013,19,36:3
6Carbon dioxide insufflation during colonoscopy in deeply sedated patients显示文摘AIM:To compare the impact of carbon dioxide(CO2) and air insufflation on patient tolerance/safety in deeply sedated patients undergoing colonoscopy.METHODS:Patients referred for colonoscopy were randomized to receive either CO2 or air insufflation during the procedure.Both the colonoscopist and patient were blinded to the type of gas used.During the procedure,insertion and withdrawal times,caecal intubationrates,total sedation given and capnography readings were recorded.The level of sedation and magnitude of patient discomfort during the procedure was assessed by a nurse using a visual analogue scale(VAS)(0-3).Patients then graded their level of discomfort and abdominal bloating using a similar VAS.Complications during and after the procedure were recorded.RESULTS:A total of 142 patients were randomized with 72 in the air arm and 70 in the CO2 arm.Mean age between the two study groups were similar.Insertion time to the caecum was quicker in the CO2 group at 7.3 min vs 9.9 min with air(P = 0.0083).The average withdrawal times were not significantly different between the two groups.Caecal intubation rates were 94.4% and 100% in the air and CO2 groups respectively(P = 0.012).The level of discomfort assessed by the nurse was 0.69(air) and 0.39(CO2)(P = 0.0155) and by the patient 0.82(air) and 0.46(CO2)(P = 0.0228).The level of abdominal bloating was 0.97(air) and 0.36(CO2)(P = 0.001).Capnography readings trended to be higher in the CO2 group at the commencement,caecal intubation,and conclusion of the procedure,even though this was not significantly different when compared to readings obtained during air insufflation.There were no complications in both arms.CONCLUSION:CO2 insufflation during colonoscopy is more efficacious than air,allowing quicker and better cecal intubation rates.Abdominal discomfort and bloating were significantly less with CO2 insufflation.Rajvinder Singh Eu Nice Neo Nazree Nordeen Ganesananthan Shanmuganathan Angelie Ashby Sharon Drummond Garry Nind Elizabeth Murphy Andrew Luck Graeme Tucker William Tam 2012World Journal of Gastroenterology2012,18,25:3

10Analysis of orthopedic surgical procedures in children with cerebral palsy显示文摘BACKGROUND Orthopedic surgery in children with cerebral palsy(CP)aims to improve function and prevent deformities.Each child’s condition in CP is unique and many covariables influence surgical decision-making including a patient's age and their functional level.Little is known about the frequency of different types of orthopedic surgery in children with CP who have varied functional levels,particularly in countries from Latin America.AIM To assess the type of orthopedic surgical procedures in relation to age and gross motor function in children with CP.METHODS This retrospective study included all children with CP(n=245)treated with elective orthopedic surgery at a Uruguayan university hospital between October 2010 and May 2016 identified from a surgical database.Eighteen children(7%)were lost to follow-up due to missing medical charts.Demographics,gross motor function classification(GMFCS),and orthopedic surgeries were obtained from the medical records of 227 children.Chi-squared tests and analysis of variance were used to assess the frequency of surgery,accounting for GMFCS levels.Mean age for soft tissue vs bone surgery was compared with the independent samples t-test.RESULTS A total of 711 surgical procedures were performed between 1998 and 2016.On average,children had 3.1 surgical procedures and the mean age at first surgery was 8.0 years.There were no significant differences in age at first surgery among GMFCS levels(P=0.47).The most common procedures were lower leg soft tissue surgery(n=189,27%),hip tenotomy(n=135,19%),and hamstring tenotomy(n=104,14%).For children with GMFCS level Ⅰ,the mean number of surgeries per child[1.8(range 1-9)]differed significantly at P<0.05 in children with GMFCS levels Ⅱ[3.2(1-12)],Ⅲ[3.2(1-8)],Ⅳ[3.3(1-13)],and Ⅴ[3.6(1-11)].Within Ⅱ,Ⅲ,Ⅳ,and Ⅴ,there was no significant difference in mean number of surgeries per child when comparing across the groups.The proportion of soft tissue surgery vs bone surgery was higher in GMFCS levels Ⅰ-Ⅲ(80%-85%)compared to levels IV(68%)and V(55%)(P<0.05).CONCLUSION The frequency of surgical procedures per child did not increase with higher GMFCS level after level Ⅰ.However,the proportion of bone surgery was higher in GMFCS levels Ⅳ-Ⅴ compared to Ⅰ-Ⅲ.Ignacio Rehbein Viviana Teske Ignacio Pagano Alejandro Cúneo María Elena Pérez Johan von Heideken 2020World Journal of Orthopedics2020,11,4:2
11The importance of an indigenous tree to southern African communities with specific relevance to its domestication and commercialization: a case of the marula tree显示文摘Local communities in southern Africa derive many benefits from marula [Sclerocarya birrea(A.Rich.) Hochst.subsp.caffra(Sond.) Kokwaro].These include the contribution of this species towards health,nutrition,food security and conservation by sharing local skills and knowledge related to it.Marula fruits can be eaten fresh,squeezed to make juice,brewed in traditional beer or used to make jam and jelly.The kernels are also edible and can be pressed to extract oil for cooking and cosmetics,i.e.,for skin and hair application.The bark,roots,seeds and leaves are exploited for traditional medicinal purposes.Marula has acquired significant commercial value since its fruits and other products have entered local,regional and international trade in southern Africa.To diver-sify fruit production and satisfy the increasing demands for this resource,several domestication initiatives have been carried out at regional and international levels.The accumulated knowledge and skills relevant to the establishment and commercialization of marula therefore provide an effective guide in areas where marula remains undomesticated or underutilized.We discuss the great importance of marula in southern Africa to reveal its great potential to regions where it remains unexploited.Neo C MOKGOLODI DING You-fang Moffat P SETSHOGO MA Chao LIU Yu-jun 2011Forestry Studies in China2011,13,1:2
