  • Liver biopsy is a procedure that involves obtaining a small piece of liver tissue, which is then analyzed in the laboratory. Liver biopsy may be used to evaluate a mass seen on images, diagnose unexplained liver diseases or abnormal liver function tests, and to determine the severity of the liver disease including hepatitis, fibrosis, and steatosis. Liver biopsy is an invasive procedure, and its complications are rare but potentially lethal. Therefore, it is necessary to perform liver biopsy safely from clinical aspect and to take specimen steadily from a pathological one....

  • The gold standard of assessing liver fibrosis is liver biopsy, which is invasive and not without risk. Therefore, searching for noninvasive serologic biomarkers for liver fibrosis is an importantly clinical issue. Methods: A total of 16 healthy volunteers and 45 patients with chronic hepatitis C virus (HCV) were enrolled (F0: n = 16, F1: n = 7, F2: n = 17, F3: n = 8 and F4: n = 13, according to the METAVIR classification). Three serum samples of each fibrotic stage were analyzed by two-dimension difference gel electrophoresis (2D-DIGE). The differential proteins were identified by...

  • Of the four heart valves, the mitral valve is the only valve that has a distinguishable annulus. However, the presence of a fibrous annular structure is variable and discontinuous. The firmest site of support for the mitral valve is the region of fibrous continuity between the aortic and mitral valves, the extent of which is delineated by the right and left fibrous trigones (Fig. 2). Nevertheless, for surgical purposes, the annulus is considered the area of attachment of the valve leaflets to the atrial muscle. The annulus is a functional component of the mitral valve.

  • Non-invasive Breslow index determination would allow one-time procedure for melanoma clinical management which would be of utmost medical interest for several reasons: unimpaired sentinel lymph node status, low morbidity, pain and stress associated to surgical excision margins. However, as explained throughout the current chapter, such a determination requires melanoma diagnosis prior to Breslow determination.

  • In the section on ‘Lentiviral Vector’, the generation of high-titre lentiviral vectors capable of efficiently expressing transgenes over long periods of time is governed by a number of vector design rules. Chapter thirteen highlights the guiding design principles and the technical of the successful lentiviral gene vector design. Chapter fourteen reviews current status of lentiviral vector development, especially the progress in the lentiviral vector systems allowing the controlling of gene expression.

  • Presti et al. took two extra biopsies laterally on each side at the base and mid gland in addition to the traditional sextant technique in an effort to include more peripheral zone tissue in their sampling (Presti et al., 2000). This produced a 10-core biopsy. They enrolled 483 men with either abnormal DRE or a PSA 4 ng/mL. On analysis of the cancer detection rate from each side, it was discovered that the traditional sextant technique missed 20% of cancers.

  • Đàn bà 58 tuổi vào bnhân vì đau bụng, ultrasound / CAT scan cho thấy một khối 11 cm ở thùy phải của gan. Cái khó của case này không phải ở chỗ định bệnh, vì ngay từ lúc đầu phải nghi là ung thư, và biopsy cho thấy đúng là ung thư. Khi thấy ung thư ở gan, thì chia ngay ra ung thư phát ra ngay từ gan (có thể gọi "primary liver tumor" cho dễ hiểu) (tức là hepatoma) hay ung thư từ nơi khác chạy tới gan (metastasis). Ở đàn bà 58 tuổi, nếu là metastases,...

  • Prenatal diagnosis, traditionally used as a synonymous for invasive fetal testing and evaluation of chromosomal constellation, presently encompasses many other issues like pedigree analyses, fetal risk assessment, population screening, genetic counseling and fetal diagnostic testing as well. Ultrasound guided chorionic villus samling (CVS), amniocentesis and, to a lesser extent, fetal blood sampling are used routinely in fetal medicine units. Other fetal tissue biopsies such as skin, liver and muscle biopsy are used only rarely.
