Hepatocellular carcinoma (HCC), represents more than 85% of liver cancers. The diagnosis of HCC may be delayed due to the absence of early, sensitive and specific biomarkers. This study was conducted to investigate whether the expression of thioredoxin (Trx) and glutaredoxin (Grx) is helpful for HCC diagnosis in an experimental model. Twenty male albino rats were equally divided into two groups (HCC and control). Hepatocarcinogenesis was performed by single intraperitoneal (i.p) injection of 200?mg/kg of diethylnitrosamine (DENA). Two weeks later, 0.05% of phenobarbital (PB) was supplied in the drinking water for other 14 weeks. HCC was diagnosed by measuring serum alpha-fetoprotein (AFP) level and histopathological examination. Our results found that hepatic indices alanine transaminase (ALT), aspartate transaminase (AST), total bilirubin were elevated but decreased total protein level. Lipid peroxidation was elevated through increasing hepatic content of MDA with decreased antioxidant parameters like hepatic SOD, CAT activities and GSH. The current study also found that Trx and Grx tissue genes were overexpressed in HCC group significantly, compared to control group. This study substantiated that increased expression of these enzymes may be predictive of outcomes in HCC. 相似文献

Aims: The aim of this study was to explore the family members' determinant of the delay in seeking psychiatric care to patients diagnosed with psychosis. Methods: Qualitative semi-structured interviews were carried out with twenty-seven family members of patients with psychosis at psychiatric outpatient clinics in Amman, Jordan. Results: The findings revealed that perceived stigma and fears about being labelled are the main barriers to requesting early psychiatric health care. The participants cited many different reasons linked to finding help led to delay in seeking help in the early stages of the illness including misattribution of the cause and symptoms of mental illness, family and financial factors. Conclusions: The study highlights the importance of enhancing knowledge about the schizophrenia-related spectrum to ensure patients seek treatment in a more timely manner. 相似文献

Three‐dimensional transesophageal echocardiography incremental value in a rare case of a bileaflet tricuspid valve 下载免费PDF全文
Hani M. Mahmoud M.B.B.Ch M.Sc. F.A.S.E. Hossam Walley M.D. Hatem Hosny M.Sc. Magdi Yacoub F.R.C.S. F.R.S. 《Echocardiography (Mount Kisco, N.Y.)》2016,33(9):1438-1440
Detailed assessment of the tricuspid valve using two‐dimensional echocardiography is always challenging, as only two of three leaflets can be seen at a time. Three‐dimensional echocardiography can provide the enface view of the tricuspid valve that allows simultaneous visualization of all of the three leaflets. In a 42‐year‐old male patient scheduled for pulmonary endarterectomy, 3DTEE showed that the tricuspid valve is bileaflet, with one septal and another lateral leaflet. There were two commissures, one of them is anteriorly positioned and the other one is posterior. Our findings were confirmed intra‐operatively by direct surgical visualization of the tricuspid valve. 相似文献

Alopecia areata (AA) is a recurrent, immune‐mediated, hair‐loss disorder. It is associated with other autoimmune disorders that carry a high risk of cardiovascular disease (CVD). However, there is a lack of reports on the association of cardiovascular comorbidities and AA. Cardiac troponin I is a biomarker of myocardial ischaemia and inflammation, while N‐terminal pro‐B‐type natriuretic peptide is used in the diagnosis of congestive heart failure. This study was conducted to assess the serum level of both markers by ELISA in 44 patients with AA compared with 44 healthy controls (HCs). None of the participants had CVD, CVD risk factors or other diseases associated with elevation of either marker. The study revealed that serum levels of both markers were significantly higher in patients with AA compared with HCs (P < 0.001). The inflammatory milieu encountered in AA may be associated with subtle myocardial inflammation that causes elevation of levels of both of these cardiac markers. 相似文献

ObjectiveWe conducted a systematic review and dose–response meta-analysis of prospective studies to summarize findings on the associations between intakes of soy, soy isoflavones, and soy protein and risk of mortality from all causes, cancers, and cardiovascular diseases.MethodsOnline databases were systematically searched to identify relevant articles published earlier than May 2018. We applied restricted cubic splines using random-effects analysis to assess dose–response associations. Between-study heterogeneity was assessed by I2 value and Cochrane Q test. Potential publication bias was assessed by visual inspection of funnel plots and Begg regression test.ResultsIn total, 23 prospective studies with an overall sample size of 330,826 participants were included in the current systematic review and the meta-analysis. Soy/soy products consumption was inversely associated with deaths from cancers (pooled relative risk 0.88, 95% CI 0.79 to 0.99; P=0.03; I2=47.1%, 95% CI 0.0% to 75.4%) and cardiovascular diseases (pooled effect size: 0.85, 95% CI 0.72 to 0.99; P=0.04; I2=50.0%, 95% CI 0.0% to 77.6%). Such significant associations were also observed for all-cause mortality in some subgroups of the included studies, particularly those with higher quality. In addition, higher intake of soy was associated with decreased risk of mortality from gastric, colorectal, and lung cancers as well as ischemic cardiovascular diseases. Participants in the highest category of dietary soy isoflavones intake had a 10% lower risk of all-cause mortality compared with those in the lowest category. We also found that a 10-mg/day increase in intake of soy isoflavones was associated with 7% and 9% decreased risk of mortality from all cancers and also breast cancer respectively. Furthermore, a 12% reduction in breast cancer death was indicated for each 5-g/day increase in consumption of soy protein. However, intake of soy protein was not significantly associated with all-cause and cardiovascular diseases mortality.ConclusionsSoy and its isoflavones may favorably influence risk of mortality. In addition, soy protein intake was associated with a decreased risk in the mortality of breast cancer. Our findings may support the current recommendations to increase intake of soy for greater longevity. 相似文献
