BACKGROUND Lignin and hemicelluloses are the major components limiting enzyme infiltration into cell walls. Determination of the topochemical distribution of lignin and aromatics in sugar cane might provide important data on the recalcitrance of specific cells. We used cellular ultraviolet (UV) microspectrophotometry (UMSP) to topochemically detect lignin and hydroxycinnamic acids in individual...

AIM To evaluate the feasibility and efficacy of percutaneous transhepatic lymphosonography (PTL) as a novel method for the detection of tumor lymphangiogenesis in hepatic VX(2) of rabbits and to evaluate combined PTL and routine contrast-enhanced ultrasonographic imaging for the diagnosis of liver cancer. METHODS Ten rabbits with VX(2) tumor were included in this study. SonoVue (0.1 mL/kg) wa...

OBJECTIVE To clarify the validity of the evaluation of the hemodynamics of hepatic lesions < or =20 mm in diameter using contrast-enhanced ultrasonography (CE-US) with Sonazoid. METHODS Sixty-two hepatic lesions in 55 patients with chronic hepatitis or cirrhosis due to hepatitis C virus were studied. We evaluated by quantitative analysis the time intensity curve (TIC) on hepatic lesion and pa...

We previously described a selective bile duct ligation model to elucidate the process of hepatic fibrogenesis in children with biliary atresia or intrahepatic biliary stenosis. Using this model, we identified changes in the expression of alpha smooth muscle actin (α-SMA) both in the obstructed parenchyma and in the hepatic parenchyma adjacent to the obstruction. However, the expression profiles...

This review outlines current trends in applying texture analysis for the treatment of patients with renal parenchyma tumor. The prospects using radiomics diagnosis and cell carcinoma are presented.

BACKGROUND The molecular profile of peritumoral non-neoplastic liver parenchyma (PNLP) has recently been suggested as predictive factor of early and late recurrence of hepatocellular carcinoma (HCC). However, there is no definite cut-off point for tumor-free PNLP in terms of either histological or molecular changes. Therefore, our aim is to determine the numerical cut-off point for separating a...

PURPOSE The aim of this study was to explore the usefulness of the resistive index (RI) on spectral Doppler ultrasonography (US) in the detection of renal cell carcinoma (RCC) in patients with end-stage renal disease (ESRD). METHODS Seventeen ESRD patients with kidneys in which renal masses were suspected in routine US were subjected. They underwent computed tomography scans and additional Do...

BACKGROUND Preoperative bronchoscopic tumour ablation has been suggested as a beneficial treatment for bronchopulmonary carcinoid tumours, although data regarding its effects and long-term outcome are lacking. METHODS In our case-matched cohort study with 208 patients with bronchopulmonary carcinoid tumours we investigated the role of preoperative bronchoscopic interventions before subsequent...

In order to study the effect of inter-tissue correlations on the organogenetic capacities of various tissues of stem segments of Torenia fournieri Lind, different types of explants were excised and grown separately: epidermis, subepidermal parenchyma, epidermis plus subepidermal parenchyma but devoid of vascular tissue and stem segments devoid of epidermis.The epidermis, normally capable of bud...
