| 1 | Ischemia/reperfusion injury and cardioprotective mechanisms:Role of mitochondria and reactive oxygen species显示文摘Reperfusion therapy must be applied as soon as possible to attenuate the ischemic insult of acute myocardial infarction(AMI).However reperfusion is responsible for additional myocardial damage,which likely involves opening of the mitochondrial permeability transition pore(mPTP).In reperfusion injury,mitochondrial damage is a determining factor in causing loss of cardiomyocyte function and viability.Major mechanisms of mitochondrial dysfunction include the long lasting opening of mPTPs and the oxidative stress resulting from formation of reactive oxygen species(ROS).Several signaling cardioprotective pathways are activated by stimuli such as preconditioning and postconditioning,obtained with brief intermittent ischemia or with pharmacological agents.These pathways converge on a common target,the mitochondria,to preserve their function after ischemia/reperfusion.The present review discusses the role of mitochondria in cardioprotection,especially the involvement of adenosine triphosphate-dependent potassium channels,ROS signaling,and the mPTP.Ischemic postconditioning has emerged as a new way to target the mitochondria,and to drastically reduce lethal reperfusion injury.Several clinical studies using ischemic postconditioning during angioplasty now support its protective effects,and an interesting alternative is pharmacological postconditioning.In fact ischemic postconditioning and the mPTP desensitizer,cyclosporine A,have been shown to induce comparable protection in AMI patients. | Maria-Giulia Perrelli Pasquale Pagliaro Claudia Penna | 2011 | World Journal of Cardiology2011，3，6： | 64 |
| 2 | Pediatric functional constipation treatment with Bifi dobacterium-containing yogurt:A crossover,double-blind,controlled trial显示文摘AIM: To evaluate the treatment of pediatric functional chronic intestinal constipation (FCIC) with a probiotic goat yogurt. METHODS: A crossover double-blind formula-controlled trial was carried out on 59 students (age range: 5-15 years) of a public school in Belo Horizonte, MG, Brazil, presenting a FCIC diagnostic, according to Roma Ⅲ criteria. The students were randomized in two groups to receive a goat yogurt supplemented with 109 colony forming unit/mL Bifidobacterium longum (B.longum) (probiotic) daily or only the yogurt for a period of 5 wk (formula). Afterwards, the groups were intercrossed for another 5 wk. Defecation frequency, stool consistency and abdominal and defecation pain were assessed.RESULTS: Both treatment groups demonstrated improvement in defecation frequency compared to baseline. However, the group treated with probiotic showed most signif icant improvement in the f irst phase of the study. An inversion was observed after crossing over, resulting in a reduction in stool frequency when this group was treated by formula. Probiotic and formula improved stool consistency in the f irst phase of treatment, but the improvement obtained with probiotic was significantly higher (P = 0.03). In the second phase of treatment, the group initially treated with probiotic showed worseningstool consistency when using formula. However, the difference was not signif icant. A signif icant improvement in abdominal pain and defecation pain was observed with both probiotic and formula in the first phase of treatment, but again the improvement was more signif icant for the group treated with B. longum during phase I (P < 0.05). When all data of the crossover study were analyzed, significant differences were observed between probiotic yogurt and yogurt only for defecation frequency (P = 0.012), defecation pain (P = 0.046) and abdominal pain (P = 0.015). | Paula VP Guerra Luiza N Lima Tassia C Souza Vanessa Mazochi Francisco J Penna Andreia M Silva Jacques R Nicoli Elizabet V Guimares | 2011 | World Journal of Gastroenterology2011，17，34： | 25 |
| 3 | Biological mesh reconstruction of the pelvic floor following abdominoperineal excision for cancer:A review显示文摘Extralevator abdominoperineal excision and pelvic exenteration are mutilating operations that leave wide perineal wounds.Such large wounds are prone to infection and perineal herniation,and their closure is a major concern to most surgeons.Different approaches to the perineal repair exist,varying from primary or mesh closure to myocutaneous flaps.Each technique has its own associated advantages and potential complications and the ideal approach is still debated.In the present study,we reviewed the current literature and our own local data regarding the use of biological mesh for perineal wound closure.Current evidence suggests that the use of biological mesh carries an acceptable risk of wound complications compared to primary closure and is similar to flap reconstruction.In addition,the rate of perineal hernia is lower in early follow-up,while long-term hernia occurrence appears to be similar between the different techniques.Finally,it is an easy and quick reconstruction method.Although more expensive than primary closure,the cost associated with the use of a biological mesh is at least equal,if not less,than flap reconstruction. | Boris Schiltz Nicolas Christian Buchs Marta Penna Cosimo Riccardo Scarpa Emilie Liot Philippe Morel Frederic Ris | 2017 | World Journal of Clinical Oncology2017，8，3： | 10 |
| 4 | Transanal total mesorectal excision: Myths and reality显示文摘Transanal total mesorectal excision(TaTME) is a new and promising approach for the treatment of rectal cancer. Whilst the experience is still limited, there are growing evidences that this approach might overcome the limits of standard low anterior resection. TaTME might help to decrease the conversion rate especially in difficult patients, and to improve the pathological results, while preserving the urogenital function. Evaluation of data from large registries and randomized studies should help to draw firmer conclusions. Beyond these technical considerations, the next challenge seems to be clearly the safe introduction of this approach, motivating the development of dedicated courses. | Nicolas C Buchs Marta Penna Alexander L Bloemendaal Roel Hompes | 2016 | World Journal of Clinical Oncology2016，7，5： | 5 |
| 5 | A self-made, low-cost infrared system for evaluating the sciatic functional index in mice显示文摘The sciatic functional index(SFI) is a popular parameter for peripheral nerve evaluation that relies on footprints obtained with ink and paper. Drawbacks include smearing artefacts and a lack of dynamic information during measurement. Modern applications use digitized systems that can deliver results with less analytical effort and fewer mice. However, the systems are expensive(€40,000). This study aimed to evaluate the applicability and precision of a self-made, low-cost infrared system for evaluating SFI in mice. Mice were subjected to unilateral sciatic nerve crush injury(crush group; n = 7) and sham operation(sham group; n = 4). They were evaluated on the day before surgery, the 2^(nd), 4^(th) and 6^(th) days after injury, and then every day up to the 23^(rd) day after injury. We compared two SFI evaluation methods, i.e., conventional inkand-paper SFI(C-SFI) and our infrared system(I-SFI). Our apparatus visualized footprints with totally internally reflected infrared light(950 nm) and a camera that can only detect this wavelength. Additionally we performed an analysis with the ladder beam walking test(LBWT) as a reference test. I-SFI assessment reduced the standard deviation by about 33 percent, from 11.6 to 7.8, and cut the variance around the baseline to 21 percent. The system thus requires fewer measurement repetitions and fewer animals, and cuts the cost of keeping the animals. The apparatus cost €321 to build. Our results show that the process of obtaining the SFI can be made more precise via digitization with a self-made, low-cost infrared system. | Lukas Fricker Vincenzo Penna Florian Lampert G.Bjoern Stark Christian Witzel Georgios Koulaxouzidis | 2016 | Neural Regeneration Research2016，11，5： | 4 |
| 6 | Immunohistochemical expression of intrarenal renin angiotensin system components in response to tempol in rats fed a high salt diet显示文摘AIM To determine the effect of tempol in normal rats fed high salt on arterial pressure and the balance between antagonist components of the renal renin-angiotensin system.METHODS Sprague-Dawley rats were fed with 8% Na Cl highsalt(HS) or 0.4% Na Cl(normal-salt,NS) diet for 3 wk,with or without tempol(T)(1 mmol/L,administered in drinking water). Mean arterial pressure(MAP),glomerularfiltration rate(GFR),and urinary sodium excretion(UVNa) were measured. We evaluated angiotensin Ⅱ(Ang Ⅱ),angiotensin 1-7(Ang 1-7),angiotensin converting enzyme 2(ACE2),mas receptor(Mas R),angiotensin type 1 receptor(AT1R) and angiotensin type 2 receptor(AT2R) in renal tissues by immunohistochemistry.RESULTS The intake of high sodium produced a slight but significant increase in MAP and differentially regulated components of the renal renin-angiotensin system(RAS). This included an increase in Ang Ⅱ and AT1 R,and decrease in ACE-2 staining intensity using immunohistochemistry. Antioxidant supplementation with tempol increased natriuresis and GFR,prevented changes in blood pressure and reversed the imbalance of renal RAS components. This includes a decrease in Ang Ⅱ and AT1 R,as increase in AT2,ACE2,Ang(1-7) and Mas R staining intensity using immunohistochemistry. In addition,the natriuretic effects of tempol were observed in NS-T group,which showed an increased staining intensity of AT2,ACE2,Ang(1-7) and Mas R.CONCLUSION These findings suggest that a high salt diet leads to changes in the homeostasis and balance between opposing components of the renal RAS in hypertension to favour an increase in Ang Ⅱ. Chronic antioxidant supplementation can modulate the balance between the natriuretic and antinatriuretic components of the renal RAS. | Gabriel Cao Silvana Lorena Della Penna Nicolas Martín Kouyoumdzian Marcelo Roberto Choi Susana Gorzalczany Belisario Enrique Fernández Jorge Eduardo Toblli María Inés Roson | 2017 | World Journal of Nephrology2017，6，1： | 4 |
| 7 | Radiation-induced in vitro mutagenesis system for salt tolerance and other agronomic characters in sugarcane(Saccharum officinarum L.)显示文摘Gamma ray-induced in vitro mutagenesis and selection for salt(NaC l) tolerance were investigated in sugarcane(Saccharum officinarum L.). Embryogenic callus cultures were irradiated(10 to 80 Gy) and subjected to in vitro selection by exposure of irradiated callus to NaC l(0, 50, 100,150, 200, and 250 mmol L-1). Increasing NaC l concentrations resulted in growth reduction and increased membrane damage. Salt-selected callus lines were characterized by the accumulation of proline, glycine betaine, and Na+and K+concentration. Higher accumulation of proline and glycine betaine was observed in NaC l stressed callus irradiated at 20 Gy. Na+concentration increased and K+concentration decreased with increasing salt level. Irradiated callus showed50–60% regeneration under NaC l stress, and in vitro-regenerated plants were acclimatized in the greenhouse, with 80–85% survival. A total of 138 irradiated and salt-selected selections were grown to maturity and their agronomic performance was evaluated under normal and saline conditions. Of these, 18 mutant clones were characterized for different agro-morphological characters and some of the mutant clones exhibited improved sugar yield with increased Brix%,number of millable canes, and yield. The result suggest that radiation-induced mutagenesis offers an effective way to enhance genetic variation in sugarcane. | Ashok A.Nikam Rachayya M.

| 8 | Can baseline ML Flow test results predict leprosy reactions? An investigation in a cohort of patients enrolled in the uniform multidrug therapy clinical trial for leprosy patients in Brazil显示文摘Background:The predictive value of the serology to detection of IgM against the Mycobacterium leprae-derived phenolic glycolipid-I/PGL-I to identify leprosy patients who are at higher risk of developing reactions remains controversial.Whether baseline results of the ML Flow test can predict leprosy reactions was investigated among a cohort of patients enrolled in The Clinical Trial for Uniform Multidrug Therapy for Leprosy Patients in Brazil(U-MDT/CT-BR).Methods:This was a descriptive study focusing on the main clinical manifestations of leprosy patients enrolled in the U-MDT/CT-BR from March 2007 to February 2012 at two Brazilian leprosy reference centers.For research purposes,753 leprosy patients were categorized according to a modified Ridley-Jopling(R&J)classification and according to the development of leprosy reactions(reversal reaction/RR and erythema nodosum leprosum/ENL),and whether they had a positive or negative bacillary index/BI.Results:More than half of the patients(55.5%)reported leprosy reaction:18.3%(138/753)had a RR and 5.4%(41/753)had ENL.Leprosy reactions were more frequent in the first year following diagnosis,as seen in 27%(205/753)of patients,while 19%(142/753)developed reactions during subsequent follow-up.Similar frequencies of leprosy reactions and other clinical manifestations were observed in paucibacillary(PB)and multibacillary(MB)leprosy patients treated with U-MDT and regular MDT(R-MDT)(P=0.43 and P=0.61,respectively).Compared with PB patients,leprosy reactions were significantly more frequent in MB patients with a high BI,and more patients developed RR than ENL.However,RR and neuritis were also reported in patients with a negative BI.At baseline,the highest rate of ML Flow positivity was observed in patients with a positive BI,especially those who developed ENL,followed by patients who had neuritis and RR.Among reaction-free patients,81.9%were ML Flow positive,however,the differences were not statistically significant compared to reactional patients(P=0.45).Conclusions:MB and PB patients treated with R-MDT and U-MDT showed similar frequencies of RR and other clinical manifestations.Positive ML Flow tests were associated with MB leprosy and BI positivity.However,ML Flow test results at baseline showed limited sensitivity and specificity for predicting the development of leprosy reactions. | Emerith Mayra Hungria Regiane Morillas Oliveira Gerson Oliveira Penna Lúcio Cartaxo Aderaldo Maria Araci de Andrade Pontes Rossilene Cruz Heitor de SáGonçalves Maria Lúcia Fernandes Penna Ligia Regina Franco Sansigolo Kerr Mariane Martins de Araújo Stefani Samira Bührer-Sékula | 2016 | Infectious Diseases of Poverty2016，5，1： | 2 |

| 10 | Time course of physiological,biochemical,and gene expression changes under short-term salt stress in Brassica juncea L.显示文摘Salinity-imposed limitations on plant growth are manifested through osmotic and ionic imbalances. However, because salinity-induced responses vary considerably among crop plants, monitoring of such responses at an early stage has relevance. In this study,physiological(seed germination, seed vigor index, root length, shoot length, fresh weight,dry weight) and biochemical attributes(osmoprotectants, K^+/Na^+ ratio) were analyzed for a time-course assessment of salt responses in Indian mustard(Brassica juncea L.) with an emphasis on early monitoring. The results showed strong correlations for total soluble sugars at germination phase(24 h), proline content in the seedling establishment phase(48 h) and various physiological parameters including seed vigor index(R^2= 0.901), shoot length(R^2= 0.982), and fresh weight(R^2= 0.980) at 72 h(adaptation under stress). In addition, transcriptional changes were observed under NaCl treatment for key genes belonging to the family of selective ion transporters(NHX, HKT) and abscisic acid synthesis(AAO-3). The status of mitochondrial respiration was also examined as a probe for salinity tolerance at an early stage. The results suggested that although all the analyzed parameters showed correlations(negative or positive) with salt stress magnitude, their critical response times differed, with most of the studied biochemical, physiological, or molecular markers providing valuable information only after radicle emergence, whereas mitochondrial respiration via alternative oxidase was useful for the early detection of salt responses. | Manish Pandey Suprasanna Penna | 2017 | The Crop Journal2017，5，3： | 2 |
