1Stamen specification and anther development in rice显示文摘Male reproductive development is a complex biological process which includes the formation of the stamen with differentiated anther tissues, in which microspores/pollens are generated, then anther dehiscence and subsequently pollination. Stamen specification and anther development involve a number of extraordinary events such as meristem transition, cell division and differentiation, cell to cell communication, etc., which need the cooperative interaction of sporophytic and gametophytic genes. The advent of various tools for rice functional gene identification, such as complete genome sequence, genome-wide microarrays, collections of mutants, has greatly facilitated our understanding of mechanisms of rice stamen specification and anther development. Male sterile lines are critical for hybrid rice breeding, therefore understanding these processes will not only contribute greatly to the basic knowledge of crop developmental biology, but also to the development of new varieties for hybrid rice breeding in the future.ZHANG DaBing WILSON Zoe A 2009Chinese Science Bulletin2009,54,14:40
2Anther and pollen development:A conserved developmental pathway显示文摘Pollen development is a critical step in plant development that is needed for successful breeding and seed formation.Manipulation of male fertility has proved a useful trait for hybrid breeding and increased crop yield.However,although there is a good understanding developing of the molecular mechanisms of anther and pollen anther development in model species,such as Arabidopsis and rice,little is known about the equivalent processes in important crops.Nevertheless the onset of increased genomic information and genetic tools is facilitating translation of information from the models to crops,such as barley and wheat;this will enable increased understanding and manipulation of these pathways for agricultural improvement.José Fernndez Gmez Behzad Talle Zoe A Wilson 2015Journal of Integrative Plant Biology2015,57,11:33

4Platelet-to-lymphocyte ratio in the setting of liver transplantation for hepatocellular cancer: A systematic review and meta-analysis显示文摘AIM To perform a systematic review and meta-analysis on platelet-to-lymphocyte ratio(PLR) as a risk factor for post-transplant hepatocellular cancer(HCC) recurrence. METHODS A systematic literature search was performed using PubM ed. Participants of any age and sex, who underwent liver transplantation for HCC were considered following these criteria:(1) studies comparing pre-transplant low vs high PLR values;(2) studies reporting post-transplant recurrence rates; and(3) if more than one study was reported by the same institute, only the most recent was included. The primary outcome measure was set for HCC recurrence after transplantation. RESULTS A total of 5 articles, published between 2014 and 2017, fulfilled the selection criteria. As for the quality of the reported studies, all the investigated articles presented an overall high quality. A total of 899 cases were investigated: 718 cases(80.0%) were males. Three studies coming from European countries and one from Japan presented HCV as the main cause of cirrhosis. On the opposite, one Chinese study presented a greater incidence of HBV-related cirrhotic cases. In all the studies apart one, the PLR cut-off value of 150 was reported. At meta-analysis, high PLR value was associated with a significant increase in recurrence after transplantation(OR = 3.33; 95%CI: 1.78-6.25; P < 0.001). A moderate heterogeneity was observed among the identified studies according to the Higgins I^2 statistic value.CONCLUSION Pre-transplant high PLR values are connected with an increased risk of post-operative recurrence of hepatocellular cancer. More studies are needed for better clarify the biological mechanisms of this results.Quirino Lai Fabio Melandro Zoe Larghi Laureiro Francesco Giovanardi Stefano Ginanni Corradini Flaminia Ferri Redan Hassan Massimo Rossi Gianluca Mennini 2018World Journal of Gastroenterology2018,24,15:19
5Vascular endothelial growth factor for the treatment of femoral head osteonecrosis: An experimental study in canines显示文摘AIM To evaluate the treatment of osteonecrosis of the femoral head(ONFH) with the use of vascular endothelial growth factor(VEGF).METHODS In 30 mature beagles(6 groups of 5 beagles) ONFH was induced cryosurgically and one of the following solutions was administered locally in the femoral head(FH) in each group: Single injection of 500 μg VEGF(t-VEGFμ group); single injection of 500 ng VEGF(t-VEGFn group); continuous delivery of 500 μg VEGF through osmotic micropump(t-VEGFpump-μ group); continuous delivery of 500 ng VEGF through osmotic micropump(t-VEGFpump-n group); single injection of 0.9% sodium chloride(t-NS group), while one group that served as control group did not receive any local solution(No-t group). FHs were retrieved 12 wk postoperatively, underwent decalcification and hematoxylin/eosin and toluidine blue staining. In two canines per group, one half of FH was processed without decalcification and stained with modified Masson Trichrome. Histological sections were observed by light microscopy and measured with a semi-automatized bone histomorphometry system and Bone Volume/Total Volume(BV/TV), Marrow Volume/Total Volume(MaV/TV), and Trabecular Thickness(TbT h) were assessed. Standard and robust tests(Welch, Brown Forsythe) of analysis of variance along with multiple comparisons, were carried out among the categories.RESULTS The untreated(No-t) group had signs of osteonecrosis, whereas the VEGF groups revealed reversal of the osteonecrosis. Statistical analysis of the decalcified specimens revealed a significantly better BV/TV ratio and a higher Tb Th between the VEGF treatment groups(except the t-VEGFn group) and the No-t group or the control t-NS group. Single dose 500 μg VEGF group had significantly better BV/TV ratio and higher Tb Th when compared to the No-t group(50.45 ± 6.18 vs 29.50 ± 12.27, P = 0.002 and 151.44 ± 19.07 vs 107.77 ± 35.15, P = 0.161 respectively) and the control t-NS group(50.45 ± 6.18 vs 30.9 ± 6.67, P = 0.004 and 151.44 ± 19.07 vs 107.14 ± 35.71, P = 0.151 respectively). Similar differences were found for the prolonged VEGF delivery/pump groups of 500 μg and 500 ng. Analysis of the totality of specimens(decalcified/non-decalcified) enhanced the aforementioned differences and additionally revealed significant differences in the comparison of the TbT h.CONCLUSION In an experimental model of ONFH in canines it was found that local treatment with VEGF leads to bone tissue remodeling and new bone formation.Zoe H Dailiana Nikolaos Stefanou Lubna Khaldi Georgios Dimakopoulos James R Bowers Cristian Fink James R Urbaniak 2018World Journal of Orthopedics2018,9,9:13

7Hypothermic oxygenated perfusion for a steatotic liver graft显示文摘To the Editor:Donor steatosis represents a well-known risk factor for primary non-function,early allograft dysfunction,and biliary complications after liver transplantation(LT)[1,2].Recently,machine perfusion(MP)technology has been implemented in the clinical practice,with the primary intent to assess the graft quality and to optimize the organ selection process[3].A limited number of articles has been published specifically investigated the role of MP in steatotic livers[4–10],with few of them looking at the role of hypothermic MP.Quirino Lai Franco Ruberto Fabio Melandro Zoe Larghi Laureiro Massimo Rossi Gianluca Mennini 2020Hepatobiliary & Pancreatic Diseases International2020,19,1:7
8Seed metabolomic study reveals significant metabolite variations and correlations among different soybean cultivars显示文摘Soybean[Glycine max(L.) Merr.]is one of the world's major crops,and soybean seeds are a rich and important resource for proteins and oils.While 'omics' studies,such as genomics,transcriptomics,and proteomics,have been widely applied in soybean molecular research,fewer metabolomic studies have been conducted for largescale detection of low molecular weight metabolites,especially in soybean seeds.In this study,we investigated the seed metabolomes of 29 common soybean cultivars through combined gas chromatography-mass spectrometry and ultra-performance liquid chromatography-tandem mass spectrometry.One hundred sixty-nine named metabolites were identified and subsequently used to construct a metabolic network of mature soybean seed.Among the 169 detected metabolites,104 were found to be significantly variable in their levels across tested cultivars.Metabolite markers that could be used to distinguish genetically related soybean cultivars were also identified,and metabolitemetabolite correlation analysis revealed some significant associations within the same or among different metabolite groups.Findings from this work may potentially provide the basis for further studies on both soybean seed metabolism and metabolic engineering to improve soybean seed quality and yield.Hong Lin Jun Rao Jianxin Shi Chaoyang Hu Fang Cheng Zoe A.Wilson Dabing Zhang Sheng Quan 2014Journal of Integrative Plant Biology2014,56,9:7
9Development and use of biomaterials as wound healing therapies显示文摘There is a vast number of treatments on the market for the management of wounds and burns,representing a multi-billion dollar industry worldwide.These include conventional wound dressings,dressings that incorporate growth factors to stimulate and facilitate the wound healing process,and skin substitutes that incorporate patientderived cells.This article will review the more established,and the recent advances in the use of biomaterials for wound healing therapies,and their future direction.Rachael Zoe Murray Zoe Elizabeth West Allison June Cowin Brooke Louise Farrugia 2019Burns & Trauma2019,7,1:5
10Aplastic anemia and severe pancytopenia during treatment with peg-interferon,ribavirin and telaprevir for chronic hepatitis C显示文摘Telaprevir and Boceprevir are the first direct acting antivirals approved for chronic hepatitis C in combination with peg-interferon alfa and ribavirin.Pancytopenia due to myelotoxicity caused by these drugs may occur,but severe hematological abnormalities or aplastic anemia(AA) have not been described.We collected all cases of severe pancytopenia observed during triple therapy with telaprevir in four Spanish centers since approval of the drug in 2011.Among 142 cirrhotic patients receiving treatment,7 cases of severe pancytopenia(5%) were identified and three were consistent with the diagnosis of AA.Mean age was 59 years,five patients had compensated cirrhosis and two patients had severe hepatitis C recurrence after liver transplantation.Severe pancytopenia was diagnosed a median of 10 wk after the initiation of therapy.Three patients had pre-treatment hematological abnormalities related to splenomegaly.In six patients,antiviral treatment was interrupted at the onset of hematological abnormalities.Two patients died due to septic complications and one patient due to acute alveolar hemorrhage.The remaining patients recovered.Severe pancytopenia and especially AA,are not rare during triple therapy with telaprevir in patients with advanced liver disease.Close monitoring is imperative in this setting to promptly detect serious hematological disorders and to prevent further complications.Sabela Lens Jose L Calleja Ana Campillo Jose A Carrion Teresa Broquetas Christie Perello Juan de la Revilla Zoe Marino Maria-Carlota Londono Jose M Sanchez-Tapias Alvaro Urbano-Ispizua Xavier Forns 2015World Journal of Gastroenterology2015,21,17:4
11Uncommon indications for associating liver partition and portal vein ligation for staged hepatectomy:a systematic review显示文摘Associating liver partition and portal vein ligation for staged hepatectomy(ALPPS)represents an innovative surgical technique used for the treatment of large hepatic lesions at high risk for post-resection liver failure due to a small future liver remnant.The most significant amount of literature concerns the use of ALPPS for the treatment of hepatocellular carcinoma(HCC),cholangiocarcinoma(CCC),and colorectal liver metastases(CRLM).On the opposite,few is known about the role of ALPPS for the treatment of uncommon liver pathologies.The objective of the present study was to evaluate the current literature on this topic.A systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA)guidelines.Eligible articles published up to February 2020 were included using the MEDLINE,Scopus,and Cochrane databases.Among the 486 articles screened,45 papers met the inclusion criteria,with 136 described cases of ALPPS for rare indications.These 136 cases were reported in 18 different countries.Only in two countries,namely Germany and Brazil,more than ten cases were observed.As for the ALPPS indications,we reported 41(30.1%)cases of neuroendocrine tumor(NET)metastases,followed by 27(19.9%)cases of gallbladder cancer(GBC),nine(6.6%)pediatric cases,six(4.4%)gastrointestinal stromal tumors,six(4.4%)adult cases of benign primary liver disease,four(2.9%)adult cases of malignant primary liver disease,and 43(31.6%)adult cases of malignant secondary liver disease.According to the International ALPPS Registry data,less than 10%of the ALPPS procedures have been performed for the treatment of uncommon liver pathologies.NET and GBC are the unique pathologies with acceptable numerosity.ALPPS for NET appears to be a safe procedure,with satisfactory long-term results.On the opposite,the results observed for the treatment of GBC are poor.However,these data should be considered with caution.The rationale for treating benign pathologies with ALPPS appears to be weak.No definitive response should be given for all the other pathologies.Multicenter studies are needed with the intent to clarify the potentially beneficial effect of ALPPS for their treatment.Quirino Lai Gianluca Mennini Zoe Larghi Laureiro Massimo Rossi 2021Hepatobiliary Surgery and Nutrition2021,10,2:4
12Dietary stimulation of the endogenous somatotropic axis in weaner and growerfinisher pigs using medium chain triglycerides and cysteamine hydrochloride显示文摘Background: Three experiments were conducted to examine the overall hypothesis that addition of medium chain triglycerides(MCT) and cysteamine hydrochloride(CSH) into the diets of young and growing pigs would stimulate the endogenous somatotropic axis to improve growth and performance.Results: In Experiment 1, weaner pigs were given either a 5 d dietary supplement of 5 % MCT(n = 8) or a control diet(n = 8). MCT increased the plasma concentration of growth hormone(GH; P < 0.05) and the GH secretagogue,ghrelin(P < 0.05). Additionally, the MCT treatment reduced scouring(P < 0.05), maintained villous height in the small intestine(P < 0.05) and stabilised daily weight gain(P < 0.05), compared to the controls. Experiment 2compared the effects of 4 levels(0, 1, 3 and 6 % v/v) of MCT supplementation in grower-finisher male pigs, of approximately 35 kg live weight(n = 15 per treatment). Blood samples taken after 7 wk of treatment showed that the MCT supplementation increased circulating ghrelin(P < 0.001), GH(P < 0.01) and insulin(P < 0.05)concentrations in a dose-dependent manner. Daily weight gain, feed intake and feed conversion ratio were not affected by the MCT diets. In Experiment 3, 64 female pigs of approximately 60 kg live weight were allocated to one of three dietary treatments: control(n = 20); 6 % MCT(n = 21); and 70 mg/kg CSH(n = 21). After 3 wk of supplementation, the MCT treated pigs had a higher plasma concentration of ghrelin compared to the control and CSH pigs(P < 0.05). Plasma concentrations of GH and weight were not affected by any of the dietary treatments.Conclusions: Evidence is provided in Experiment 1 to support the use of dietary MCT supplements, perhaps acting via stimulation of somatotropic endocrine pathways, to minimise weaning-associated disorders such as slowing of growth and diarrhoea. In Experiments 2 and 3, although there was no effect on weight gain or feed conversion ratio in either experiment, MCT and CSH increased endocrine components of the somatotropic axis.David W.Miller Zoe Prosser Edward Y.W.Chee Christian F.Hansen Frank R.Dunshea Bruce P.Mullan John R.Pluske 2017Journal of Animal Science and Biotechnology2017,8,2:3
13Heterotopic ossification after the use of recombinant human bone morphogenetic protein-7显示文摘AIM To present the incidence of heterotopic ossification after the use of recombinant human bone morphogenetic protein-7(rhB MP-7) for the treatment of nonunions.METHODS Bone morphogenetic proteins(BMPs) promote bone formation by auto-induction. Recombinant human BMP-7 in combination with bone grafts was used in 84 patients for the treatment of long bone nonunions. All patients were evaluated radiographicaly for the development of heterotopic ossification during the standard assessment for the nonunion healing. In all patients(80.9%) with radiographic signs of heterotopic ossification, a CT scan was performed. Nonunion site palpation and ROM evaluation of the adjacent jointswere also carried out. Factors related to the patient(age, gender), the nonunion(location, size, chronicity, number of previous procedures, infection, surrounding tissues condition) and the surgical procedure(graft and fixation type, amount of rhB MP-7) were correlated with the development of heterotopic ossification and statistical analysis with Pearsons χ~2 test was performed.RESULTS Eighty point nine percent of the nonunions treated with rh BMP-7, healed with no need for further procedures. Heterotopic bone formation occurred in 15 of 84 patients(17.8%) and it was apparent in the routine radiologi-cal evaluation of the nonunion site, in a mean time of 5.5 mo after the rh BMP-7 application(range 3-12). The heterotopic ossification was located at the femur in 8 cases, at the tibia in 6, and at the humerus in οne patient. In 4 patients a palpable mass was present and only in one patient, with a para-articular knee nonunion treated with rhB MP-7, the size of heterotopic ossification affected the knee range of motion. All the patients with heterotopic ossification were male. Statistical analysis proved that patient's gender was the only important factor for the development of heterotopic ossification(P = 0.007). CONCLUSION Heterotopic ossification after the use of rh BMP-7 in nonunions was common but it did not compromise the final clinical outcome in most cases, and affected only male patients.Marianthi Papanagiotou Zoe H Dailiana Theophilos Karachalios Sokratis Varitimidis Michael Hantes Georgios Dimakopoulos Marianna Vlychou Konstantinos N Malizos 2017World Journal of Orthopedics2017,8,1:3

16Clinical laboratory and imaging evidence for effectiveness of agarose-agarose macrobeads containing stem-like cells derived from a mouse renal adenocarcinoma cell population (RMBs) in treatment-resistant, advanced metastatic colorectal cancer:Evaluation of显示文摘Objective: The complexity, heterogeneity and capacity of malignant neoplastic cells and tumors for rapid change and evolution suggest that living-cell-based biological-systems approaches to cancer treatment are merited. Testing this hypothesis, the tumor marker, metabolic activity, and overall survival(OS) responses, to the use of one such system, implantable macrobeads [RENCA macrobeads(RMBs)], in phase I and IIa clinical trials in advanced,treatment-resistant metastatic colorectal cancer(m CRC) are described here.Methods: Forty-eight m CRC patients(30 females; 18 males), who had failed all available, approved treatments,underwent RMB implantation(8 RMB/kg body weight) up to 4 times in phase I and phase IIa open-label trials.Physicals, labs [tumor and inflammation markers, lactate dehydrogenase(LDH)] and positron emission tomography-computed tomography(PET-CT) imaging to measure number/volume and metabolic activity of the tumors were performed pre-and 3-month-post-implantation to evaluate safety and initial efficacy(as defined by biological responses). PET-CT maximum standard uptake value(SUVmax)(baseline and d 90; SUVmax ≥2.5), LDH,and carcinoembryonic antigen(CEA) and/or cancer antigen 19-9(CA 19-9) response(baseline, d 30 and/or d 60)were assessed and compared to OS.Results: Responses after implantation were characterized by an at least 20% decrease in CEA and/or CA 19-9 in75% of patients. Fluorodeoxyglucose(FDG)-positive lesions(phase I, 39; 2 a, 82) were detected in 37/48 evaluable patients, with 35% stable volume and stable or decreased SUV(10) plus four with necrosis; 10, increased tumor volume, SUV. LDH levels remained stable and low in Responders(R)(d 0–60, 290.4–333.9), but increased steadily in Non-responders(NR)(d 0–60, 382.8–1,278.5)(d 60, P=0.050). Responders to RMBs, indicated by the changes in the above markers, correlated with OS(R mean OS=10.76 months; NR mean OS=4.9 months; P=0.0006).Conclusions: The correlations of the tumor marker, tumor volume and SUV changes on PET-CT, and LDH levels themselves, and with OS, support the concept of a biological response to RMB implantation and the validity of the biological-systems approach to m CRC.

18LRRK2, GBA and their interaction in the regulation of autophagy: implications on therapeutics in Parkinson’s disease显示文摘Mutations in leucine-rich repeat kinase 2 (LRRK2) and glucocerebrosidase (GBA) represent two most common genetic causes of Parkinson’s disease (PD). Both genes are important in the autophagic-lysosomal pathway (ALP), defects of which are associated with α-synuclein (α-syn) accumulation. LRRK2 regulates macroautophagy via activation of the mitogen activated protein kinase/extracellular signal regulated protein kinase (MAPK/ERK) kinase (MEK) and the calcium-dependent adenosine monophosphate (AMP)-activated protein kinase (AMPK) pathways. Phosphorylation of Rab GTPases by LRRK2 regulates lysosomal homeostasis and endosomal trafficking. Mutant LRRK2 impairs chaperone-mediated autophagy, resulting in α-syn binding and oligomerization on lysosomal membranes. Mutations in GBA reduce glucocerebrosidase (GCase) activity, leading to glucosylceramide accumulation, α-syn aggregation and broad autophagic abnormalities. LRRK2 and GBA influence each other: GCase activity is reduced in LRRK2 mutant cells, and LRRK2 kinase inhibition can alter GCase activity in GBA mutant cells. Clinically, LRRK2 G2019S mutation seems to modify the effects of GBA mutation, resulting in milder symptoms than those resulting from GBA mutation alone. However, dual mutation carriers have an increased risk of PD and earlier age of onset compared with single mutation carriers, suggesting an additive deleterious effect on the initiation of PD pathogenic processes. Crosstalk between LRRK2 and GBA in PD exists, but its exact mechanism is unclear. Drugs that inhibit LRRK2 kinase or activate GCase are showing efficacy in pre-clinical models. Since LRRK2 kinase and GCase activities are also altered in idiopathic PD (iPD), it remains to be seen if these drugs will be useful in disease modification of iPD.Shirley Yin-Yu Pang Rachel Cheuk Nam Lo Philip Wing-Lok Ho Hui-Fang Liu Eunice Eun Seo Chang Chi-Ting Leung Yasine Malki Zoe Yuen-Kiu Choi Wing Yan Wong Michelle Hiu-Wai Kung David Boyer Ramsden Shu-Leong Ho 2022Translational Neurodegeneration2022,11,1:2
