1Schistosoma mansoni proteins attenuate gastrointestinal motility disturbances during experimental colitis in mice显示文摘AIM:To investigate the therapeutic effect of Schistosoma mansoni(S.mansoni) soluble worm proteins on gastrointestinal motility disturbances during experimental colitis in mice. METHODS:Colitis was induced by intrarectal injection of trinitrobenzene sulphate(TNBS) and 6 h later,mice were treated ip with S.mansoni proteins.Experiments were performed 5 d after TNBS injection.Inflammationwas quantified using validated inflammation parameters. Gastric emptying and geometric center were measured to assess in vivo gastrointestinal motility.Peristaltic activity of distal colonic segments was studied in vitro using a modified Trendelenburg set-up.Cytokine profiles of T-lymphocytes isolated from the colon were determined by real time reverse transcriptase-polymerase chain reaction. RESULTS:Intracolonic injection of TNBS caused severe colitis.Treatment with S.mansoni proteins significantly ameliorated colonic inflammation after 5 d.TNBS did not affect gastric emptying but significantly decreased the geometric center and impaired colonic peristaltic activity 5 d after the induction of colitis.Treatment with S.mansoni proteins ameliorated these in vivo and in vitro motility disturbances.In addition,TNBS injection caused a downregulation of effector T cell cytokines after 5 d,whereas a S.mansoni protein effect was no longer observed at this time point. CONCLUSION:Treatment with S.mansoni proteins attenuated intestinal inflammation and ameliorated motility disturbances during murine experimental colitis.Nathalie E Ruyssers Benedicte Y De Winter Joris G De Man Natacha D Ruyssers Ann J Van Gils Alex Loukas Mark S Pearson Joel V Weinstock Paul A Pelckmans Tom G Moreels 2010World Journal of Gastroenterology2010,16,6:11
2Orientation to learning context modulates retrieval processing for unrecognized words显示文摘Explicit memory errors may occur when individuals fail to retrieve information about items previously studied (item memory) or about the learning context (source memory). We examined electrophysiological measures during recognition failure in order to determine the influence of retrieval orientation for item versus source information. Recognition failure was associated with brain potentials distinct from those associated with success. Furthermore, source-memory failures were associated with earlier-onset brain potentials with a more anterior distribution compared to item-memory failures. Neurocognitive processing was thus modulated by retrieval orientation so as to differentially influence neural correlates of successful versus unsuccessful retrieval.GUO ChunYan CHEN WenJun TIAN Tian Ken A PALLER Joel L VOSS 2010Chinese Science Bulletin2010,55,26:6
3Hepatic ischemic preconditioning increases portal vein flow in experimental liver ischemia reperfusion injury显示文摘BACKGROUND: Ischemic preconditioning(IPC) has been shown to decrease liver injury and to increase hepatic microvascular perfusion after liver ischemia reperfusion. This study aimed to evaluate the effects of IPC on hemodynamics of the portal venous system. METHODS: Thirty-two rats were randomized into two groups: IPC group and control group. The rats of the IPC group underwent IPC by 10 minutes of liver ischemia followed by 10 minutes of reperfusion before liver ischemia, and the rats of the control group were subjected to 60 minutes of partial liver ischemia. Non-ischemic lobes were resected immediately after reperfusion. The animals were studied at 4 hours and 12 hours after reperfusion. Mean arterial pressure, heart rate, portal vein flow and pressure were analyzed. Blood was collected for the determination of the levels of aspartate aminotransferase, alanine aminotransferase, calcium, lactate, pH, bicarbonate, and base excess. RESULTS: IPC increased the mean portal vein flow at 4 hours and 12 hours after reperfusion. IPC recovered 78% of the meanportal vein flow at 12 hours after reperfusion. IPC decreased the levels of aspartate aminotransferase, alanine aminotransferase and lactate, and increased the levels of ionized calcium, bicarbonate and base excess at 12 hours after reperfusion. CONCLUSIONS: This study demonstrated that IPC increases portal vein flow and enhances hepatoprotective effects in liver ischemia reperfusion. The better recovery of portal vein flow after IPC may be correlated with the lower levels of transaminases and with the better metabolic profile.Estela RR Figueira Joel A Rocha-Filho Mauro Nakatani Marcelo FS Buto Eduardo R Tatebe Vitor O Andre Ivan Cecconello Luiz AC D'Albuquerque 2014Hepatobiliary & Pancreatic Diseases International2014,13,1:6
4Imaging of the temporomandibular joint: An update显示文摘Imaging of the temporomandibular joint(TMJ) is continuously evolving with advancement of imaging technologies. Many different imaging modalities are currently used to evaluate the TMJ. Magnetic resonance imaging is commonly used for evaluation of the TMJ due to its superior contrast resolution and its ability to acquire dynamic imaging for demonstration of the functionality of the joint. Computed tomography and ultrasound imaging have specific indication in imaging of the TMJ. This article focuses on state of the art imaging of the temporomandibular joint. Relevant normal anatomy and biomechanics of movement of the TMJ are discussed for better understanding of many TMJ pathologies. Imaging of internal derangements is discussed in detail. Different arthropathies and commontumors are also discussed in this article.Asim K Bag Santhosh Gaddikeri Aparna Singhal Simms Hardin Benson D Tran Josue A Medina Joel K Curé 2014World Journal of Radiology2014,6,8:5
5Vascular depression for radiology: A review of the construct,methodology,and diagnosis显示文摘Vascular depression(VD)as defined by magnetic resonance imaging(MRI)has been proposed as a unique subtype of late-life depression.The VD hypothesis posits that cerebrovascular disease,as characterized by the presence of MRIdefined white matter hyperintensities,contributes to and increases the risk for depression in older adults.VD is also accompanied by cognitive impairment and poor antidepressant treatment response.The VD diagnosis relies on MRI findings and yet this clinical entity is largely unfamiliar to neuroradiologists and is rarely,if ever,discussed in radiology journals.The primary purpose of this review is to introduce the MRI-defined VD construct to the neuroradiology community.Case reports are highlighted in order to illustrate the profile of VD in terms of radiological,clinical,and neuropsychological findings.A secondary purpose is to elucidate and elaborate on the measurement of cerebrovascular disease through visual rating scales and semi-and fully-automated volumetric methods.These methods are crucial for determining whether lesion burden or lesion severity is the dominant pathological contributor to VD.Additionally,these rating methods have implications for the growing field of computer assisted diagnosis.Since VD has been found to have a profile that is distinct from other types of late-life depression,neuroradiologists,in conjunction with psychiatrists and psychologists,should consider VD in diagnosis and treatment planning.Sara N Rushia Al Amira Safa Shehab Jeffrey N Motter Dakota A Egglefield Sophie Schiff Joel R Sneed Ernst Garcon 2020World Journal of Radiology2020,12,5:5

7Pentoxifylline enhances the protective effects of hypertonic saline solution on liver ischemia reperfusion injury through inhibition of oxidative stress显示文摘BACKGROUND:Liver ischemia reperfusion(IR)injury triggers a systemic inflammatory response and is the main cause of organ dysfunction and adverse postoperative outcomes after liver surgery.Pentoxifylline(PTX)and hypertonic saline solution(HTS)have been identified to have beneficial effects against IR injury.This study aimed to investigate if the addition of PTX to HTS is superior to HTS alone for the prevention of liver IR injury.Vinicius Rocha-Santos Estela RR Figueira Joel A Rocha-Filho Ana MM Coelho Rafael Soraes Pinheiro Telesforo Bacchella Marcel CC Machado Luiz AC D'Albuquerque 2015Hepatobiliary & Pancreatic Diseases International2015,14,2:3
8Mammary gland growth and vascularity at parturition and during lactation in primiparous ewes fed differing levels of selenium and nutritional plane during gestation显示文摘Background: Objectives were to examine the effects of selenium(Se) supply and maternal nutritional plane during gestation on mammary gland growth, cellular proliferation, and vascularity at parturition and d 20 of lactation. Rambouillet primiparous ewes(n = 84) were allocated to treatments in a 2 x 3 factorial. Factors were dietary Se(adequate Se [ASe, 11.5 μg/kg BW] or high Se [HSe, 77.0 μg/kg BW]) and nutritional plane(60% [RES], 100% [CON], or 140% [EXC]). At parturition, lambs were removed and 42 ewes(7/treatment) were necropsied. Remaining ewes were fed a common diet meeting requirements for lactation and mechanically milked twice daily until necropsy on d 20. At both necropsy periods, mammary glands were dissected and tissues harvested. Samples were analyzed for RNA, DNA, and protein content, cell proliferation, and vascularity. Where interactions were present(P ≤ 0.05), least squares means from the highest-order interaction are presented. Results: Final body weight of ewes was least(P ≤ 0.002) in RES, intermediate for CON, and greatest for EXC, regardless of stage of the ewe at necropsy(parturition or d 20 of lactation). In ewes necropsied at parturition, mammary glands were heavier(P = 0.02) in EXC compared to RES, with CON intermediate. Concentration of RNA(mg/g) was decreased(P = 0.01) in EXC compared to CON at parturition. There was a tendency(P = 0.07) for a Se by nutrition interaction in percentage of cells proliferating where ASe-EXC ewes had greater(P ≤ 0.02) number of proliferating cells then all other treatments. Mammary vascular area tended(P = 0.08) to be affected by a Se by nutrition interaction where ASe-CON had less(P = 0.007) vascular area than HSe-CON ewes. In ewes necropsied at d 20 of lactation, the number of alveoli per area was decreased(P ≤ 0.05) in RES compared to CON and EXC-fed ewes. Conclusions: Results of this study indicate that proper maternal nutritional plane during gestation is important for mammary gland development, even out to d 20 of lactation.Tammi L Neville Allison M Meyer Arshi Reyaz Pawel B Borowicz Dale A Redmer Lawrence P Reynolds Joel S Caton Kimberly A Vonnahme 2013Journal of Animal Science and Biotechnology2013,4,4:3
9Liver dysfunction and SARS-CoV-2 infection显示文摘Severe acute respiratory syndrome coronavirus 2 infection is the cause of coronavirus disease 2019(COVID-19),which predominantly affects the respiratory system;it also causes systemic and multi-organic disease.Liver damage is among the main extrapulmonary manifestations.COVID-19-associated liver injury is defined as any liver damage occurring during the disease course and treatment of COVID-19 in patients with or without pre-existing liver disease,and occurs in approximately one in five patients.Abnormal liver test results have been associated with a more severe course of COVID-19 and other complications,including death.Mechanisms linking COVID-19 to liver injury are diverse.Particular consideration should be made for patients with pre-existing liver disease,such as metabolic dysfunction-associated fatty liver disease,chronic liver disease due to viral or autoimmune disease,liver transplant carriers,or cirrhosis,given the risk for more severe outcomes.This manuscript summarizes the current lines of evidence on COVID-19-associated liver injury regarding pathophysiology,clinical significance,and management in both patients with or without preexisting liver disease,to facilitate clinicians’access to updated information and patient care.Finally,we mention the ideas and recommendations to be considered for future research.Abraham Edgar Gracia-Ramos Joel Omar Jaquez-Quintana Raúl Contreras-Omaña Moises Auron 2021World Journal of Gastroenterology2021,27,26:2

11Serum vitamin D content is associated with semen|parameters and serum testosterone levels in men显示文摘The present study aimed to evaluate the influence of serum vitamin D levels on semen quality and testosterone levels.This is a crosssectional study conducted at Androscience,Science and Innovation Center in Andrology and High-Complex Clinical and Andrology Laboratory in Sao Paulo,Brazil,with 508 male patients,aged 18-60 years,from 2007 to 2017.Seminal parameters and serum sexual hormones were correlated with serum vitamin D concentrations in 260 men selected by strict selection criteria.Patients were divided into normozoospermic group(NZG,n=124)and a group with seminal abnormalities(SAG,n=136).Evaluation included complete physical examination,past medical history,habits and lifestyle factors,two complete seminal analysis with sperm functional tests,serum levels of 25-hydroxy-vitamin D_(3)(25(OH)VD_(3)),total and free testosterone,luteinizing hormone(LH),follicle-stimulating hormone(FSH),sex hormone-binding globulin(SHBG),total cholesterol,homeostatic model assessment of insulin resistance(HOMA-IR)index,and karyotype.The mean concentration of 25(OH)VD_(3)was significantly lower in the SAG(P<0.001)and positively correlated with all baseline seminal parameters and total testosterone levels.In addition,serum vitamin D_(3)concentration was found to be positively correlated with sperm concentration(β=2.103;P<0.001),total number of spermatozoa with progressive motility(β=2.069;P=0.003),total number of motile spermatozoa(β=2.571;P=0.015),and strict morphology(β=0.056;P=0.006),regardless of other variables.This is the first comparative study to address the issue of serum vitamin D_(3)content between normozoospermic patients and those with sperm abnormalities.It clearly demonstrates a direct and positive relationship between serum vitamin D level and overall semen quality,male reproductive potential,and testosterone levels.Inari M Ciccone Elaine MF Costa Juliana R Pariz Thiago A Teixeira Joel R Drevet Parviz Gharagozloo Robert J Aitken Jorge Hallak 2021Asian Journal of Andrology2021,23,1:2
