1EFFECTS OF ACUPUNCTURE ON IMMUNE RESPONSE RELATED TO OPIOID-LIKE PEPTIDES显示文摘Experimental research has recently shown that acupuncture induces the formation of opioid-like peptides (OLPs) in animals. In order to provide further evidence, we tested the β-endorphin levels and other parameters (VIP, lymphocyte subsets, NK cells and monocyte phagocytosis) in a group of 90 patients suffering from various painful disorders treated with acupuncture. Zusanli (St 36) and Hegu (LI 4) acupoints were selected. A homogeneous group of 30 subjects was used as control. Evaluation of the above parameters was made with 3 series of blood tests before treatment, 30 minutes and 24 hours after acupuncture treatment. In the acupuncture group, the following results were achieved: 1) A considerable increase in β-endorphin levels remained high even 24 hours after acupuncture treatment. In addition, we demonstrated an inverted correlation between β-endorphins and VIP; 2) 30 minutes after acupuncture session, 80% of the treated patients showed a significant increase of CD3 and CD4 values and an increase of CD8 24 hours after stimulation; 3) Monocyte phagocytosis was increased in 45% of the treated subjects 30 minutes from starting treatment, and in 100% of them after 24 hours. The percentage of NK cells was also increased in 40% of cases after 30 minutes, and in 50% after 24 hours. However, in the control group, no such significant changes in immune parameters were found.FILOMENA PETTI ALFIO BANGRAZI ALDO LIGUORI GABRIELLA REALE FLORA IPPOLITI 1998Journal of Traditional Chinese Medicine1998,18,1:20
2Amelioration of experimental colitis by Astragalus membranaceus through anti-oxidation and inhibition of adhesion molecule synthesis显示文摘AIM: To investigate the protective effects of Astragalus membranaceus(Am) against hapten-induced colitis in male Sprague-Dawley rats as well as its underlying mechanism.METHODS: Experimental colitis was induced in rats by enema administration of 2,4-dinitrobenzene sulfonic acid (DNBS). Rats were either pretreated with Am extract (2 or 4 g/kg, p.o. once daily) starting from 10 d before DNBS enema, or received Am post-treatment (2 or 4 g/kg, p.o.twice daily) on the three consecutive days following DNBS administration. Colonic lesion area and histological damage were determined, while the activities of myeloperoxidase (MPO) and xanthine oxidase, as well as reduced glutathione (GSH) content were measured in the excised colonic tissues. Besides, protein expression of inducible nitrite oxide synthase (iNOS), intercellular adhesion molecule-1 (ICAM-1) and P-selectin was also detected by Western blot analysis.RESULTS: Our findings had shown that both macroscopic lesion area and histological colonic damage induced by DNBS were significantly reduced by both Am pre- and post-treatments. These were accompanied by attenuation of the elevated colonic MPO activity and downregulation of the iNOS, P-selectin, and ICAM-1 protein expression.Besides, deprivation of colonic GSH level under colitis condition was also preserved.CONCLUSION: These results demonstrate that Am possesses both preventive and therapeutic potential in experimental colitis. The anti-inflammatory actions involve anti-oxidation along with inhibition of adhesion molecule synthesis in the colonic tissues.Joshua Ka-Shun Ko Flora Ying-Lee Lam Andrew Pok-Lap Cheung 2005World Journal of Gastroenterology2005,11,37:17
3Depression and chronic heart failure in the elderly: an intriguing relationship显示文摘长期的心失败和压抑的混乱有高流行和发生在老。几研究显示出消沉怎么趋于加重共存的长期的心失败和它的临床的结果并且反过来也如此,在特别老。在长期的心失败和消沉在之间的否定协同老可以被接近仅仅考虑位于两个这些条件下面的 multifaceted pathophysiological 特征,例如行为因素, neurohormonal 激活,煽动性的调停人, hypercoagulability 和脉管的损坏。不过,在这二个条件之间的 pathophysiological 连接还很好没被建立。尽管有在长期的心失败的消沉的高流行老病人和它的否定预示的价值,因为分享的症状,它特别经常是未被认出的。用可靠问询表,屏蔽心情混乱因此与长期的心失败在老病人被推荐,就算不能由心理健康职业运动员代替诊断会见。在这个背景,消沉的治疗要求包括的一条多学科的途径:心理疗法,抗抑郁剂,锻练训练和 electroconvulsive 治疗。尽管有冲突结果,有选择血清素举起禁止者的药理学治疗改进生活的质量但是不保证更好的结果。锻练训练在改进生活和预后的质量是有效的,但是同时心脏的康复服务是极大地 underutilized。Ilaria Liguori Gennaro Russo Francesco Curcio Giuseppe Sasso David Della-Morte Gaetano Gargiulo Flora Pirozzi Francesco Cacciatore Domenico Bonaduce Pasquale Abete Gianluca Testa 2018Journal of Geriatric Cardiology2018,15,6:16
4Cholangiocarcinoma:principles and current trends显示文摘BACKGROUND:Cholangiocarcinoma(CCA)is a lethal cancer of the biliary epithelium,originating from the liver(intrahepatic),at the confluence of the right and left hepatic ducts(hilar)or in the extrahepatic bile ducts.It is a rare malignancy associated with poor prognosis.DATA SOURCES:We searched the PubMed/MEDLINE database for relevant articles published from 1989 to 2008.The search terms used were related to 'cholangiocarcinoma' and its ' treatment'.Although no language restrictions were imposed initially,for the full-text review and final analysis,our resources only permitted the review of articles published in English.This review deals with the treatment of cholangiocarcinoma,the principles and the current trends.RESULTS:The risks and prognostic factors,symptoms and differential diagnosis are thoroughly discussed.In addition,the tools of preoperative diagnosis such as endoscopic retrograde cholangiopancreatography,digital image analysis,fluorescence in situ hybridization and magnetic resonance cholangiopancreatography are reviewed.Moreover,the treatment of CCA is discussed.CONCLUSIONS:The only curative treatment available is surgical management.Unfortunately,many patients present with unresectable tumors,the majority of whom die within a year of diagnosis.Surgical treatment involves major resections of the liver,pancreas and bile duct,with considerable mortality and morbidity.However,in selected cases and where indicated,appropriate management with aggressive surgery may achieve a good outcome with a prolonged survival expectancy.George N Zografos Athanasios Farfaras Flora Zagouri Dimosthenis Chrysikos Kostas Karaliotas 2011Hepatobiliary & Pancreatic Diseases International2011,10,1:14
5Houshiheisan and its components promote axon regeneration after ischemic brain injury显示文摘Houshiheisan,a classic prescription in traditional Chinese medicine,contains Flos Chrysanthemi,Radix Saposhnikoviae,Ramulus Cinnamomi,Rhizoma Chuanxiong,Radix et Rhizoma Asari,Radix Platycodonis,Rhizoma Atractylodis macrocephalae,Poria,Rhizoma Zingiberis,Radix Angelicae sinensis,Radix et Rhizoma Ginseng,Radix Scutellariae and Concha Ostreae.According to traditional Chinese medicine theory,Flos Chrysanthemi,Radix Saposhnikoviae,Ramulus Cinnamomi,Rhizoma Chuanxiong,Radix et Rhizoma Asari and Radix Platycodonis are wind-dispelling drugs;Rhizoma Atractylodis macrocephalae,Poria,Rhizoma Zingiberis,Radix Angelicae sinensis and Radix et Rhizoma Ginseng are deficiency-nourishing drugs.A large number of randomized controlled trials have shown that Houshiheisan is effective in treating stroke,but its mechanism of action is unknown.Axonal remodeling is an important mechanism in neural protection and regeneration.Therefore,this study explored the effect and mechanism of action of Houshiheisan on the repair of axons after cerebral ischemia.Rat models of focal cerebral ischemia were established by ligating the right middle cerebral artery.At 6 hours after model establishment,rats were intragastrically administered 10.5 g/kg Houshiheisan or 7.7 g/kg wind-dispelling drug or 2.59 g/kg deficiency-nourishing drug.These medicines were intragastrically administered as above every 24 hours for 7 consecutive days.Houshiheisan,and its wind-dispelling and deficiency-nourishing components reduced the neurological deficit score and ameliorated axon and neuron lesions after cerebral ischemia.Furthermore,Houshiheisan,and its wind-dispelling and deficiency-nourishing components decreased the expression of proteins that inhibit axonal remodeling:amyloid precursor protein,neurite outgrowth inhibitor protein A(Nogo-A),Rho family small GTPase A(Rho A) and Rho-associated kinase 2(Rock2),and increased the expression of growth associated protein-43,microtubule-associated protein-2,netrin-1,Ras-related C3 botulinum toxin substrate 1(Rac1) and cell division cycle 42(Cdc42).The effect of Houshiheisan was stronger than wind-dispelling drugs or deficiency-nourishing drugs alone.In conclusion,Houshiheisan,and wind-dispelling and deficiency-nourishing drugs promote the repair of axons and nerve regeneration after cerebral ischemia through Nogo-A/Rho A/Rock2 and Netrin-1/Rac1/Cdc42 signaling pathways.These effects are strongest with Houshiheisan.Yue Lu Flora Hsiang Jia-Hui Chang Xiao-Quan Yao Hui Zhao Hai-Yan Zou Lei Wang Qiu-Xia Zhang 2018Neural Regeneration Research2018,13,7:14
6Study on Cytokines IL-2,IL-6,IL-10 in Patients of Chronic Allergic Rhinitis Treated with Acupuncture显示文摘Objectives: To observe the plasmatic concentration of IL-6, IL-10 and IL-2 in the patient of chronic allergic rhinitis before and after acupuncture therapy. Methods: Cytokine levels were determined before and after treatment in 30 healthy volunteers (Group A) and 90 patients of chronic allergic rhinitis (Group B) with an increased plasma IL-10 level. Group B was then divided into 3 subgroups: 30 patients treated with real acupuncture (Group B1); 30 patients treated with sham acupuncture (Group B2); 30 non-treated patients (Group B3). Results: The allergic subjects of group B1, compared with controls, showed a significant reduction of IL-10 after a specific treatment with acupuncture (P<0.05). On the other hand, in those patients treated with sham acupuncture (B2) as well as in non-treated patients (B3), the IL-10 values remained high and unchanged. There was a statistically significant change in IL-2 values at 24 hours (P<0.05) after real acupuncture (Groups A, B1), however the values remained within normal ranges. The IL-6 do not change after therapy. Conclusion: The acupuncture treatment can reduce plasmatic level of IL-10 in chronic allergic rhinitis.FILOMENA BANGRAZI PETTI M.Sc.Ph.D. ALDO LIGUORI M.D. FLORA IPPOLITI M.D.Ph.D. 2002Journal of Traditional Chinese Medicine2002,22,2:12
7Cardiovascular and metabolic effects of Berberine显示文摘Berberine(BBR) is a natural alkaloid isolated from the Coptis Chinensis.While this plant has been used in Ay-urvedic and Chinese medicine for more than 2500 years,interest in its effects in metabolic and cardiovascular disease has been growing in the Western world in the last decade.Many papers have been published in these years reporting beneficial effects in carbohydrate and lip-id metabolism,endothelial function and the cardiovascu-lar system.In this review,we report a detailed analysis of the scientific literature regarding this topic,describing the effects and the underlying mechanisms of BBR on carbohydrate and lipid metabolism,endothelial function and the cardiovascular system.Flora Affuso Valentina Mercurio Valeria Fazio Serafino Fazio 2010World Journal of Cardiology2010,2,4:10
8A nutraceutical combination improves insulin sensitivity in patients with metabolic syndrome显示文摘AIM:To test the efficacy of a proprietary nutraceutical combination in reducing insulin resistance associated with the metabolic syndrome(MetS).METHODS:Sixty-four patients with MetS followed at a tertiary outpatient clinic were randomly assigned to receive either placebo or a proprietary nutraceutical combination(AP)consisting of berberine,policosanol and red yeast rice,in a prospective,double-blind,placebo-controlled study.Evaluations were performed at baseline and after 18 wk of treatment.The homeostasis model assessment of insulin resistance(HOMAIR)index was the primary outcome measure.Secondary endpoints included lipid panel,blood glucose and insulin fasting,after a standard mixed meal and after an oral glucose tolerance test(OGTT),ow-mediated dilation(FMD),and waist circumference.RESULTS:Fifty nine patients completed the study,2 withdrew because of adverse effects.After 18 wk there was a signif icant reduction in the HOMA-IR index in the AP group compared with placebo(ΔHOMA respectively-0.6 ± 1.2 vs 0.4 ± 1.9;P < 0.05).Total and low density lipoprotein cholesterol also significantly decreased in the treatment arm compared with placebo(Δlow density lipoprotein cholesterol-0.82 ± 0.68 vs-0.13 ± 0.55 mmol/L;P < 0.001),while triglycerides,high density lipoprotein cholesterol,and the OGTT were not affected.In addition,there were significant reductions in blood glucose and insulin after the standard mixed meal,as well as an increase in FMD(ΔFMD 1.9 ± 4.2 vs 0 ± 1.9 %;P < 0.05)and a significant reduction in arterial systolic blood pressure in the AP arm.CONCLUSION:This short-term study shows that AP has relevant beneficial effects on insulin resistance and many other components of MetS.Flora Affuso Valentina Mercurio Antonio Ruvolo Concetta Pirozzi Filomena Micillo Guido Carlomagno Fabrizia Grieco Serafino Fazio 2012World Journal of Cardiology2012,4,3:7

10Gastrointestinal stromal tumor causing small bowel intussusception in a patient with Crohn’s disease显示文摘We report a case of jejunoileal intussusception in a 42-year-old patient with Crohn's disease caused by a gastrointestinal stromal tumor. The patient complained of vague diffuse abdominal pain for a period of 4 mo. Intussusception was suspected at computer tomography and magnetic resonance imaging scans. Segmental resection of the small intestine was performed. Pathological examination of the surgical specimen revealed a gastrointestinal stromal tumor as well as aphthous ulcerations and areas of inflammation, which were characteristic of Crohn's disease. This is the f irst report of small bowel intussusception due to a gastrointestinal stromal tumor coexisting with Crohn's disease.George E Theodoropoulos Dimitrios Linardoutsos Dimitrios Tsamis Paraskevas Stamopoulos Dimitrios Giannopoulos Flora Zagouri Nikolaos V Michalopoulos 2009World Journal of Gastroenterology2009,15,41:7

12Evaluation of the colorectal cancer risk conferred by rare UNC5C alleles显示文摘AIM:To evaluate the risk associated with variants of the UNC5C gene recently suspected to predispose to familial colorectal cancer(CRC).METHODS:We screened patients with familial CRC forms as well as patients with sporadic CRCs.In a first time,we analyzed exon 11 of the UNC5C gene in 120unrelated patients with suspected hereditary CRC,58patients with suspected Lynch-associated cancer or polyposis,and 132 index cases of Lynch syndrome families with a characterized mutation in a DNA mismatch repair(MMR).Next,1023 patients with sporadic CRC and1121 healthy individuals were screened for the variants identified in patients with familial cancer.RESULTS:Of 120 patients with familial CRC of unknown etiology,one carried the previously reported mis-sense mutation p.Arg603Cys(R603C)and another exhibited the unreported variant of unknown significance p.Thr617Ile(T617I).The p.Ala628Lys(A628K)mutation previously described as the main UNC5C risk variant for familial CRC was not detected in any cases of familial CRC of unknown etiology,but was present in a patient with familial gastric cancer and in two Lynch syndrome patients in co-occurrence with MMR mutations.A statistically non-significant increase in cancer risk was identified in familial CRC and/or other Lynchassociated cancers(1/178 patients vs 2/1121 healthy controls,OR=3.2,95%CI:0.29-35.05,P=0.348)and in sporadic CRCs(4/1023 patients vs 2/1121 healthy controls,OR=2.2,95%CI:0.40-12.02,P=0.364).CONCLUSION:We confirm that UNC5C mutations are very rare in familial and sporadic CRCs,but further investigations are needed to justify routine UNC5C testing for diagnostic purposes.Sébastien Küry Céline Garrec Fabrice Airaud Flora Breheret Virginie Guibert Cécile Frenard Shuo Jiao Dominique Bonneau Pascaline Berthet Céline Bossard Olivier Ingster Estelle Cauchin Stéphane Bezieau 2014World Journal of Gastroenterology2014,20,1:4
13扩大圆锭结晶器冷却水出口区显示文摘在过去的几年中,圆锭结晶器已有了几次改进。尽管这些改进主要限于结晶器,但却改善了整个铸造系统的效能。双排喷水孔可增大冷却水的喷射角和喷射速度,减少冲击铸锭后飞溅离开铸锭表面的水量。这些改进提高了二次水冷效果,允许在铸速相同的情况下采用更长的结晶器膛。由于这种结构的结晶器冷却效果提高,故在水温一定的条件下,可减少冷却水的用量。石墨环结构及其材质的改进使铸锭质量提高,结晶器维修工作量减少。这种双排射流结晶器可制成一体式。Jeffrey W.Allen,Robert B.Wagstaff,K.

16The P132H mutation in the main protease of Omicron SARSCoV-2 decreases thermal stability without compromising catalysis or small-molecule drug inhibition显示文摘Dear Editor,The ongoing SARS-CoV-2 pandemic continues to be a significant threat to global health.First reported in November 2021,the Omicron variant(B.1.1.529)is more transmissible and can evade immunity better than previous SARS-CoV-2 variants,fueling an unprecedented surge in cases.To produce functional proteins from its polyprotein,SARS-CoV-2 relies on the cysteine proteases Nsp3/papain-like protease(PLpro)and Nsp5/main protease(Mpro)/3C-like protease to cleave at three and more than 11 sites,respectively.1 Therefore,Mpro and PLpro inhibitors are considered to be one of the most promising SARS-CoV-2 antivirals.On December 22,2021,the Food and Drug Administration(FDA)issued an Emergency Use Authorization(EUA)for PAXLOVID,a ritonavir-boosted formulation of nirmatrelvir.Nirmatrelvir is a first-in-class orally bioavailable SARSCoV-2 Mpro inhibitor.2 Thus,the scientific community must vigilantly monitor potential mechanisms of drug resistance,especially because SARS-CoV-2 is naïve to Mpro inhibitors.Mutations have been well identified in variants to this point.3 Notably,Omicron Mpro(OMpro)harbors a single mutation—P132H.In this study,we characterized the enzymatic activity,drug inhibition,and structure of OMpro while evaluating the past and future implications of Mpro mutations.Michael Dominic Sacco Yanmei Hu Maura Verenice Gongora Flora Meilleur Michael Trent Kemp Xiujun Zhang Jun Wang Yu Chen 2022Cell Research2022,32,5:3

18A new green process for biodiesel production from waste oils via catalytic distillation using a solid acid catalyst-Modeling, economic and environmental analysis显示文摘The challenges in the chemical processing industry today are environmental concerns, energy and capital costs. Catalytic distillation(CD) is a green reactor technology which combines a catalytic reaction and separation via distillation in the same distillation column. Utilization of CD in chemical process development could result in capital and energy savings, and the reduction of greenhouse gases. The efficacy of CD and the economic merits, in terms of energy and equipment savings, brought by CD for the production of biodiesel from waste oil such as yellow grease is quantified. Process flow sheets for industrial routes for an annual production of 10 million gallon ASTM purity biodiesel in a conventional process(reactor followed by distillation) and CD configurations are modeled in Aspen Plus. Material and energy flows, as well as sized unit operation blocks, are used to conduct an economic assessment of each process. Total capital investment, total operating and utility costs are calculated for each process. The waste oil feedstock is yellow grease containing both triglyceride and free fatty acid. Both transesterification and esterification reactions are considered in the process simulations. Results show a significant advantage of CD compared to a conventional biodiesel processes due to the reduction of distillation columns, waste streams and greenhouse gas emissions. The significant savings in capital and energy costs together with the reduction of greenhouse gases demonstrate that process intensification via CD is a feasible and new green process for the biodiesel production from waste oils.Aashish Gaurav Flora T.T.Ng Garry L.Rempel 2016Green Energy & Environment2016,1,1:3
19Anticancer potential of metabolic compounds from marine actinomycetes isolated from Lagos Lagoon sediment显示文摘Thirty-two actinomycetes strains were isolated from sediment samples from 12 different sites at Lagos Lagoon and identified using standard physiological and biochemical procedures as well as 16S rDNA gene sequence analysis. Secondary metabolites were extracted from the strains and their anticancer activity on the K562 (Human acute myelocytic leukemia), HeLa (cervical carcinoma), AGS (Human gastric), MCF- 7 (breast adenocarcinoma) and HL-60 (Human acute promyelocytic leukemia) cell lines was determined. The metabolic extracts exhibited cytotoxicity with IC50 values ranging from 0.030 mg/mL to 4.4 mg/mL. The Streptomyces bingchenggensis ULS14 extract was cytotoxic against all the cell lines tested. The bioactivity-guided extraction and purification of the metabolic extracts from this strain yielded two purified anticancer compounds: ULDF4 and ULDF5. The structures of the extracted compounds were determined using spectroscopic analyses, including electrospray ionization mass spectrophotometer and nuclear magnetic resonance (1 Dimensional and 2 Dimensional), and were shown to be structurally similar to staurosporine and kigamicin. The IC50 of ULDF4 and ULDF5 against the HeLa cell line was 0.034 mg/mL and 0.075 mg/mL, respectively. This study is the first to reveal the anticancer potential of actinomycetes from Lagos Lagoon, which could be exploited for therapeutic purposes.Olabisi Flora Davies-Bolorunduro Isaac Adeyemi Adeleye Moshood Olushola Akinleye Peng George Wang 2019Journal of Pharmaceutical Analysis2019,9,3:3
