AIM To compare lymphocyte subsets between healthy controls and alcoholics with liver disease. METHODS The patient cohort for this study included individuals who were suspected to have alcoholic liver disease (ALD) and who had undergone liver biopsy (for disease grading and staging, doubts about diagnosis, or concurrent liver disease; n = 56). Normal(More)
BACKGROUND AND AIMS Hepcidin plays a crucial role in iron metabolism, preventing its absorption at the basolateral enterocyte membrane. Hepcidin regulation is complex and regulated at the transcriptional level. The relation between iron overload and alcoholic liver disease is well known, but its mechanism is not clear. We present an observational,(More)
BACKGROUND The relation between alcoholic liver disease (ALD) and iron overload is well known. Liver biopsy is the gold standard for assessing iron stores. MRI is also validated for liver iron concentration (LIC) assessment. We aimed to assess the effect of active drinking in liver iron stores and the practicability of measuring LIC by MRI in ALD patients.(More)
BACKGROUND Bevacizumab has become standard of care as first-line treatment of metastatic colorectal cancer (mCRC), after proving increased response rates and improvement in survival outcomes. Hypertension (HTN) is a common complication of the treatment with bevacizumab and, owing to its close relation with antiangiogenic mechanism, may represent a clinical(More)
Most patients on chronic oral anticoagulant therapy are monitored through anticoagulation clinics, or rather by assistant physicians. Our aim was to compare warfarin anticoagulated patients who were treated with usual medical care (assistant physician) with those treated routinely at an anticoagulation clinic for anticoagulation control. The later was(More)
In this paper we provide a generalization of weak oblivious transfer through the constructive cryptography framework. This generalization requires the global order of the inputs and outputs from and to two parties called Alice and Bob to be completely defined, a subtlety which has been overlooked by previous work on the subject. We provide evidence that the(More)
This paper discusses how social network analyses and graph theory can be implemented in team sports performance analyses to evaluate individual (micro) and collective (macro) performance data, and how to use this information for designing practice tasks. Moreover, we briefly outline possible limitations of social network studies and provide suggestions for(More)
