Injection Spectroscopy of Deep Traps in Nanostructured Films of Cadmium Sulfide
Nanocrystallin CdS films with controlled stoichiometry deposited by CSVS were investigated by meth-od of the current-voltage characteristics in ITO/CdS /In structures. It was shown that in the case of cadmi-um excess (S Cd) charge flow mechanism is deter-mined by monomolecular recombination. In the band gap of CdS with excess of cadmium there was detect-ed localized states with energy Et = 0.514 Β± 0.026 eV, while in the material with Excess sulfur there are two localized states with energy Et1 = 0.514 Β± 0.026 eV and Et2 = 0.700 Β± 0.026 eV. Full concentration of lo-calized states is more than 2Β·1021 m-3 β 5Β·1022 m-3. Dependence of injection in parameters and nature of in-jection in the structures based on nanostructured CdS films on their stoichiometry was determined

Hepatocellular carcinoma is one of the most common causes of death from cancer and is the final stage of chronic liver disease. Hepatitis Π‘ virus is tropic to hepatic tissue, and these viruses persistent infection results in progressive inflammation of liver, fibrosis development, cirrhosis and finally to hepatocellular carcinoma. Patients of high risk group should undergo investigation of alpha-fetoprotein level and abdominal US once per 6 months for early diagnostics of hepatocellular carcinoma, at detection of any liver lesions further deep investigation including computer and magnetic-resonance tomography, guided biopsy of the lesion is indicated. Finding it in the early stages will allow to start activities that will help improve patient survival.ΠΠ΅ΠΏΠ°ΡΠΎΡΠ΅Π»Π»ΡΠ»ΡΡΠ½Π°Ρ ΠΊΠ°ΡΡΠΈΠ½ΠΎΠΌΠ° - ΠΎΠ΄Π½Π° ΠΈΠ· Π½Π°ΠΈΠ±ΠΎΠ»Π΅Π΅ ΡΠ°ΡΠΏΡΠΎΡΡΡΠ°Π½Π΅Π½Π½ΡΡ

Eradication of HCV infection in patients with liver cirrhosis: Factor of cancer prevention or carcinogenesis? [ΠΠ ΠΠΠΠΠΠ¦ΠΠ― HCV-ΠΠΠ€ΠΠΠ¦ΠΠ ΠΠ Π‘Π’ΠΠΠΠ Π¦ΠΠ Π ΠΠΠ ΠΠΠ§ΠΠΠ: Π€ΠΠΠ’ΠΠ ΠΠΠΠ¦ΠΠ ΠΠΠ ΠΠΠΠΠ¦ΠΠ ΠΠΠ ΠΠΠΠ¦ΠΠ ΠΠΠΠΠΠΠ?]
Hepatocellular carcinoma (HCC) is one of the most common causes of death from cancer and is the final stage of chronic liver disease, usually occurring in patients with cirrhosis (CP). Chronic infection with hepatitis C virus (HCV) leads to progressive liver inflammation and cirrhosis because this virus specifically affects liver tissue. Previously used interferon therapy had a relatively low efficiency and very high risks of side effects. during the period of administration of interferon (iFn) schemes it was proved that elimination of the virus significantly reduced risk of liver cancer development. discovery of direct-acting antiviral (daa) drugs have revolutionized HCV therapy with virus elimination rate of more than 95 % and an excellent safety profile. However, the risk of transformation of liver cirrhosis into hepatocellular carcinoma is still high even after complete eradication of the virus. numerous studies have shown conflicting results on the possible relationship between the use of new antiviral drugs and the increase in the frequency of newly diagnosed or recurrent hepatocellular carcinoma. thus, the long-term prognosis in terms of risk for HCC development among patients with sustained virological response (sVR) remains unclear. The purpose of the study was to analyze the literature on the effect of antiviral therapy of chronic hepatitis C with interferon-containing regimens and drugs of direct antiviral action on the risk of developing or recurring hepatocellular carcinoma. Material and Methods: We analyzed publications available from PubMed, scopus, e-library, Web of science using the key words βhepatocellular carcinomaβ, βchronic hepatitis Cβ, βdirect-acting antiviral drugsβ, βliver cirrhosisβ, βinterferonsβ, and βsustained virological responseβ. Of the 99 studies found, 21 were used to write a systematic review. Results: Eradication of the virus reduces the risks of HCC. despite reports on high risk of occurrence or recurrence of hepatocellular carcinoma in patients with cirrhosis after treatment with daas compared with interferon-containing regimens, there is not enough data confirming the direct link between the use of daas and the development of hepatocellular carcinoma. no statistically significant difference in the frequency of HCC between patients treated with interferon or daas was detected. Conclusion: Eradication of the virus is the most significant factor in the prevention of HCC; therefore, treatment of CHC should not be delayed due to the risk of HCC. Patients with liver cirrhosis require a long period of follow-up, even after successful treatment of chronic hepatitis C with daa drugs. stratification of HCC risk requires further research.

Detection of liver fibrosis and steatosis at early stages is a difficult task for clinical practice, due to the lack of early signs in routine radiation diagnostics. Aim. To evaluate the efficacy of ultrasound shear elastography and ultrasound steatometry of the liver with the use of domestic ultrasonic diagnostic system Angiodin-Sono/N-Ultra. Materials and methods. 264 people held ultrasound elastography and ultrasound steatometry. 38 patients underwent percutaneous puncture liver biopsy and subsequent pathophysiological examination. results. High correlation of fibrosis obtained at the Angiodin-Sono/N-Ultra and the leading ultrasonic systems with shear elastography was revealed. Cross-sectional comparative analysis of elasticity with the results of liver steatometry was conducted. conclusions. Results obtained in all groups correlate with the data obtained in studies on Fibroscan. When working with system Angiodin we got a simultaneous comparative analysis of elasticity with the results of liver steatosis. Results appear to be much more stable and compact than those obtained in studies on the Fibroscan. A new diagnostic criterion was revealed - the phenomenon of independence of fibrosis and steatosis indices. Β© 2020 Consilium Medikum. All rights reserved
