| 1 | Comparison of the liver stiffness measurement by transient elastography with the liver biopsy显示文摘AIM: To compare the liver stiffness (LS) measurement by transient elastography (TE) to the liver biopsy (LB)-considered the 'gold standard' in the evaluation of patients with chronic hepatitis C. METHODS: During a period of 12 mo, we evaluated 199 consecutive patients with chronic hepatitis due to hepatitis C virus (HCV), in which LB and LS assessments (by means of TE) were performed during the same session. RESULTS: Out of 199 patients, a valid measurement of the LS could not be obtained in 8. The mean value of LS in the cohort of 191 valid measurements was 8.45 ± 4.96 kPa, ranging from 2.3 to 38 kPa. The mean value of LS in patients with signifi cant fi brosis at biopsy (161 patients with F ≥ 2 according to Metavir) was 9.02 ± 5.15 kPa, significantly higher than in patients with no or mild fi brosis (30 patients with F < 2 Metavir): 5.39 ± 1.81 kPa (P < 0.0001). For a cut- off value of 6.8 kPa, the LS had a PPV of 98%, a NPV of 30.1%, a sensitivity of 59.6% and a specificity of 93.3% for the presence of signifi cant fi brosis (at least F2 Metavir), with a diagnostic performance of 77.3% (AUROC 0.773). Using this cut-off value, we reached the best discrimination between absence of fibrosis/ mild fibrosis (F < 2 Metavir) and the presence ofmoderate to severe fi brosis (F ≥ 2 Metavir). CONCLUSION: In patients with chronic hepatitis due to HCV, a cut-off value of 6.8 kPa measured by TE can differentiate between significant fibrosis and absent or mild fi brosis, with a PPV of 98%, a NPV of 30.1%, a sensitivity of 59.6%, a specificity of 93.3%, and a diagnostic performance of 77.3%. | Ioan Sporea Roxana ■irli Alexandra Deleanu Adriana Tudora Manuela Curescu Marioara Cornianu Daniela Lazǎr | 2008 | World Journal of Gastroenterology2008，14，42： | 20 |
| 2 | Oncogenic role of leptin and Notch interleukin-1 leptin crosstalk outcome in cancer显示文摘Obesity is a global pandemic characterized by high levels of body fat(adiposity) and derived-cytokines(i.e., leptin). Research shows that adiposity and leptin provide insight on the link between obesity and cancer progression. Leptin's main function is to regulate energy balance. However, obese individuals routinely develop leptin resistance, which is the consequence of the breakdown in the signaling mechanism controlling satiety resulting in the accumulation of leptin. Therefore, leptin levels are often chronically elevated in human obesity. Elevated leptin levels are related to higher incidence, increased progression and poor prognosis of several human cancers. In addition to adipose tissue, cancer cells can also secrete leptin and overexpress leptin receptors. Leptin is known to act as a mitogen, inflammatory and pro-angiogenic factor that induces cancer cell proliferation and tumor angiogenesis. Moreover, leptin signaling induces cancer stem cells, which are involved in cancer recurrence and drug resistance. A novel and complex signaling crosstalk between leptin, Notch and interleukin-1(IL-1) [Notch, IL-1 and leptin crosstalk outcome(NILCO)] seems to be an important driver of leptin-induced oncogenic actions. Leptin and NILCO signaling mediate the activation of cancer stem cells that can affect drug resistance. Thus, leptin and NILCO signaling are key links between obesity and cancer progression. This review presents updated data suggesting that adiposity affects cancer incidence, progression, and response to treatment. Here we show data supporting the oncogenic role of leptin in breast, endometrial, and pancreatic cancers. | Crystal C Lipsey Adriana Harbuzariu Danielle Daley-Brown Ruben R Gonzalez-Perez | 2016 | World Journal of Methodology2016，6，1： | 8 |
| 3 | Value of a newly sequenced bacterial genome显示文摘Next-generation sequencing(NGS) technologies have made high-throughput sequencing available to medium- and small-size laboratories, culminating in a tidal wave of genomic information. The quantity of sequenced bacterial genomes has not only brought excitement to the field of genomics but also heightened expectations that NGS would boost antibacterial discovery and vaccine development. Although many possible drug and vaccine targets have been discovered, the success rate of genome-based analysis has remained below expectations. Furthermore, NGS has had consequences for genome quality, resulting in an exponential increase in draft(partial data) genome deposits in public databases. If no further interests are expressed for a particular bacterial genome, it is more likely that the sequencing of its genome will be limited to a draft stage, and the painstaking tasks of completing the sequencing of its genome and annotation will not be undertaken. It is important to know what is lost when we settle for a draft genome and to determine the 'scientific value' of a newly sequenced genome. This review addresses the expected impact of newly sequenced genomes on antibacterial discovery and vaccinology. Also, it discusses the factors that could be leading to the increase in the number of draft deposits and the consequent loss of relevant biological information. | Eudes GV Barbosa Flavia F Aburjaile Rommel TJ Ramos Adriana R Carneiro Yves Le Loir Jan Baumbach Anderson Miyoshi Artur Silva Vasco Azevedo | 2014 | World Journal of Biological Chemistry2014，5，2： | 7 |
| 4 | Leptin signaling and cancer chemoresistance:Perspectives显示文摘Obesity is a major health problem and currently is endemic around the world. Obesity is a risk factor for several different types of cancer, significantly promoting cancer incidence, progression, poor prognosis and resistance to anti-cancer therapies. The study of this resistance is critical as development of chemoresistance is a serious drawback for the successful and effective drug-based treatments of cancer. There is increasing evidence that augmented adiposity can impact on chemotherapeutic treatment of cancer and the development of resistance to these treatments, particularly through one of its signature mediators, the adipokine leptin. Leptin is a pro-inflammatory, pro-angiogenic and pro-tumorigenic adipokine that has been implicated in many cancers promoting processes such as angiogenesis, metastasis, tumorigenesis and survival/resistance to apoptosis. Several possible mechanisms that could potentially be developed by cancer cells to elicit drug resistance have been suggested in the literature. Here, we summarize and discuss the current state of the literature on the role of obesity and leptin on chemoresistance, particularly as it relates to breast and pancreatic cancers. We focus on the role of leptin and its significance in possibly driving these proposed chemoresistance mechanisms, and examine its effects on cancer cell survival signals and expansion of the cancer stem cell sub-populations. | Pierre V Candelaria Antonio Rampoldi Adriana Harbuzariu Ruben R Gonzalez-Perez | 2017 | World Journal of Clinical Oncology2017，8，2： | 6 |
| 5 | Menopause and cognitive impairment:A narrative review of current knowledge显示文摘A severe impairment of cognitive function characterizes dementia.Mild cognitive impairment represents a transition between normal cognition and dementia.The frequency of cognitive changes is higher in women than in men.Based on this fact,hormonal factors likely contribute to cognitive decline.In this sense,cognitive complaints are more common near menopause,a phase marked by a decrease in hormone levels,especially estrogen.Additionally,a tendency toward worsened cognitive performance has been reported in women during menopause.Vasomotor symptoms(hot flashes,sweating,and dizziness),vaginal dryness,irritability and forgetfulness are common and associated with a progressive decrease in ovarian function and a subsequent reduction in the serum estrogen concentration.Hormone therapy(HT),based on estrogen with or without progestogen,is the treatment of choice to relieve menopausal symptoms.The studies conducted to date have reported conflicting results regarding the effects of HT on cognition.This article reviews the main aspects of menopause and cognition,including the neuroprotective role of estrogen and the relationship between menopausal symptoms and cognitive function.We present and discuss the findings of the central observational and interventional studies on HT and cognition. | Délio Marques Conde Roberto Carmignani Verdade Ana L R Valadares Lucas F B Mella Adriana OrcesiPedro Lucia Costa-Paiva | 2021 | World Journal of Psychiatry2021，11，8： | 3 |
| 6 | Histone deacetylases,microRNA and leptin crosstalk in pancreatic cancer显示文摘Because pancreatic cancer(PC) historically has had poor prognosis and five year survival rates,it has been intensely investigated.Analysis of PC incidence and biology has shown a link between different risk factors such as smoking,alcoholism,and obesity and disease progression.Important factors affecting PC include the epigenomic changes driven by DNA methylation and histone acetylation,and actions of microRNA inducing oncogenic or tumor suppressor effects.Studies have identified markers whose dysregulation seem to play important roles in PC progression.PC markers involve classical histone deacetylases(HDAC),PC stem cell(PCSC),and leptin.In this review,we discuss the role of several PC biomarkers,and the potential crosstalk between HDAC,microRNA,and leptin in PC progression.Dysregulated expression of these molecules can increase proliferation,survival,PCSC,resistance to chemotherapy and tumor angiogenesis.The potential relationships between these molecules are further analyzed using data from The Cancer Genome Atlas and crosstalk pathways generated by the Pathway Studio Platform(Ariadne Genomics,Inc.).Oncogenic miRNA21 and tumor suppressor miRNA200 have been previously linked to leptin signaling.Preliminary analysis of PC biopsies and signaling crosstalk suggests that the main adipokine leptin could affect the expression of microRNA and HDAC in PC.Data analysis suggests that HDAC-microRNA-leptin signaling crosstalk may be a new target for PC therapy. | Cynthia I Tchio Mantho Adriana Harbuzariu Ruben R Gonzalez-Perez | 2017 | World Journal of Clinical Oncology2017，8，3： | 2 |
