Diagnostic Utility of MicroRNAs in Pancreatic Cancers.

Pancreatic cancer (PC) is a serious malignant tumor with a high mortality rate, mainly due to late diagnosis and a lack of effective therapeutic interventions. The possibility of recognizing this cancer with reliable biomarkers using minimally invasive methods is of great importance for improving early detection, prognostic assessment, and targeted treatment methods. In recent years, small non-coding RNAs, especially microRNAs, have emerged as promising candidates for biomarkers of pancreatic cancer.

MicroRNAs as Biomarkers of Brain Tumor.

Brain tumors have been deadly cancers for years, and in most cases they are difficult to diagnose in their early stages. For this reason, researchers need to develop low-cost, sensitive methods for examining cancer biomarkers. Such biomarkers include microRNA.

Potential Diagnostic Utility of microRNAs in Gastrointestinal Cancers.

Early detection of gastrointestinal cancers is beneficial for patient survival and prognosis. MiRNAs have been shown to be potential cancer biomarkers that can be used to diagnose cancers. MiRNAs are single-stranded, small non-coding RNAs that are involved in the post-transcriptional regulation of the expression of different oncogenes.

Alzheimer's Disease-Biochemical and Psychological Background for Diagnosis and Treatment.

There is a paucity of empirical research on the use of non-pharmacological interventions to both treat and curb the spread of Alzheimer's disease (AD) across the globe. This paper examines the biochemical and clinical outlook and the social implications of the condition in relation to psychological aspects that may indicate a direction for further interventions. There is a scarcity of research on the effectiveness of using various psychological aspects of AD, a disease characterized by a process of transition from health and independence to a dependent state with a progressive loss of memory and functional skills.

The alcohol dehydrogenase isoenzyme (ADH I) as a marker of intrahepatic cholestasis of pregnancy.

Intrahepatic cholestasis of pregnancy (ICP) is an important pregnancy liver disorder. The alterations of different enzymes activity in the hepatocytes in the course of liver diseases are reflected in an increase in the activity of the corresponding enzymes in the blood. In present study we assayed the activity of alcohol dehydrogenase (ADH) and its isoenzyme in the serum of patients with ICP.

Molecular and Circulating Biomarkers of Brain Tumors.

Brain tumors are the most common malignant primary intracranial tumors of the central nervous system. They are often recognized too late for successful therapy. Minimally invasive methods are needed to establish a diagnosis or monitor the response to treatment of CNS tumors.

Serology in COVID-19: Comparison of Two Methods.

Background: The aim of our study was to examine the performance of two assays in detecting SARS-CoV-2 antibodies.

Methods: A total of 127 COVID-19 disease contacts from the Infectious Diseases Department were included. Two serological tests were used: SARS-CoV-2 IgG CMIA on the Alinity system (Abbott) and LIAISON SARS-CoV-2 S1/S2 IgG CLIA (DiaSorin).

Activity of Alcohol Dehydrogenase and Aldehyde Dehydrogenase in Lung Cancer Cells.

Background: The aim of this study was to define the alterations in the activity of alcohol dehydrogenase (ADH) isoenzymes and aldehyde dehydrogenase (ALDH) in normal and cancerous lung cells.

Materials And Methods: Lung tissues were taken from 36 patients during surgical resection of cancer. The activities of tested enzymes were measured by spectrofluorometric method (ADH I, ADH II, total ALDH) and photometric method (ADH III, ADH IV, total ADH).

Biochemical Markers of Colorectal Cancer - Present and Future.

According to a report by the National Cancer Institute, colorectal cancer (CRC) is one of the most common types of cancer worldwide. CRC is often recognized too late for successful therapy. Tumor markers have been sought for a number of years to detect the transformation of malignant cells at the earliest possible stage.

The Alterations in Alcohol Dehydrogenase Activity in the Sera of Women With Intrahepatic Cholestasis of Pregnancy.

Background/aim: The liver of pregnant women undergoes physiological and pathological changes and the changes in liver enzyme activity and release reflect changes in serum enzymatic activity. We aimed to assess the activity of alcohol dehydrogenase (ADH) isoenzymes, and aldehyde dehydrogenase (ALDH) in the sera of women with intrahepatic cholestasis of pregnancy (ICP), the most common pregnancy-related liver disease.

Patients And Methods: Serum samples were taken from 40 women with ICP in the second or third trimester of pregnancy.

Biochemical diagnostics of pancreatic cancer - Present and future.

Pancreatic cancer is one of the deadliest cancers having an exceptionally high mortality rate. Despite a relatively low incidence (10th among cancers), it is the fourth leading cause of cancer-related deaths in most developed countries. Improving early diagnosis of pancreatic cancer and strengthening the standardised comprehensive treatment remain the main focus of pancreatic cancer research.

Alcohol Dehydrogenase Isoenzymes and Aldehyde Dehydrogenase Activity in the Serum of Patients with Non-alcoholic Fatty Liver Disease.

Background/aim: Non-alcoholic liver disease (NAFLD) is one of the most common causes of chronic liver disease, and its prevalence and medical importance is increasing worldwide. Changes in enzyme activity in liver cells in various liver diseases are reflected by an increase in serum enzymatic activity. For example, alcohol dehydrogenase activity (ADH) and aldehyde dehydrogenase (ALDH), that occur in the liver in large quantities, correlate with disease severity during cirrhosis.

The Association Between Long-Term Acenocoumarol Treatment and Vitamin D Deficiency.

Objective: Both vitamin D and K2 are involved in a number of metabolic processes, including bone metabolism; however, associations between the vitamins are not fully understood. The aim of the study was to evaluate serum concentrations of 25-hydroxyvitamin D [25(OH)D] in adult patients receiving long-term acenocoumarol (AC) treatment.

Participants And Methods: In this cross-sectional study, 58 Caucasian patients (31 women, 27 men) with a median age of 65 years receiving long-term AC therapy were evaluated and compared with 35 age- and gender-matched healthy controls.

The Activity of Alcohol Dehydrogenase Isoenzymes and Aldehyde Dehydrogenase in the Sera of Patients with Autoimmune Hepatitis.

Background: Autoimmune hepatitis (AIH) is a progressive inflammatory hepatopathy and an important cause of end-stage liver. The liver cells' destruction is reflected by increased activity of different enzymes in the serum. These enzymes include alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH), which play a significant role in the metabolism of many biological substances and exist mainly in the liver.

The Alcohol Dehydrogenase Isoenzyme as a Potential Marker of Pancreatitis.

Background/aim: Human pancreas parenchyma contains various alcohol dehydrogenase (ADH) isoenzymes and also possesses aldehyde dehydrogenase (ALDH) activity. The altered activities of ADH and ALDH in damaged pancreatic tissue in the course of pancreatitis are reflected in the human serum. The aim of this study was to investigate a potential role of ADH and ALDH as markers for acute (AP) and chronic pancreatitis (CP).

Activity of alcohol dehydrogenase isoenzymes and aldehyde dehydrogenase in sera of patients with hepatitis C.

Introduction: The changes of enzyme activity in the hepatocytes in the course of different liver diseases are reflected by increase of the corresponding enzyme activity in the plasma. For example, the activities of alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) correlate with the severity of the condition during cirrhosis. In this study we measured the activity of ADH isoenzymes and ALDH in the sera of patients with hepatitis C.
