The role of FGF21 in the interplay between obesity and non-alcoholic fatty liver disease: a narrative review.

Obesity poses a significant and escalating challenge in contemporary society, increasing the risk of developing various metabolic disorders such as dyslipidemia, cardiovascular diseases, non-alcoholic fatty liver disease (NAFLD), type 2 diabetes, and certain types of cancer. The current array of therapeutic interventions for obesity remains insufficient, prompting a pressing demand for novel and more effective treatments. In response, scientific attention has turned to the fibroblast growth factor 21 (FGF21) due to its remarkable and diverse impacts on lipid, carbohydrate, and energy metabolism.

A Finite Element Method Study on a Simulation of the Thermal Behaviour of Four Methods for the Restoration of Class II Cavities.

The possibility of dental pulp damage during dental procedures is well known. According to studies, during finishing and polishing without cooling, temperatures of up to 140 °C or more can be generated. There are many studies that have analysed the influence of the finishing and polishing of fillings on the mechanical parameters, but the analysis of thermal parameters has led to uncertain results due to the difficulty of performing this in vivo.

Study on the Restoration of Class II Carious Cavities by Virtual Methods: Simulation of Mechanical Behavior.

The restoration of class II cavities is predominantly carried out with composite materials. Due to the high failure rate in restoring this type of cavity, composite materials with much-improved properties and new application techniques have been promoted. The study aimed to analyze the mechanical behavior of several topical composite materials (nanocomposites, nanohybrids and ormocer) using different application techniques.

Mortality Rate in Upper Gastrointestinal Bleeding Associated with Anti-Thrombotic Therapy Before and During Covid-19 Pandemic.

Introduction: During the last few years, a progressive higher proportion of patients have had upper gastrointestinal bleeding (UGIB) related to antithrombotic therapy. The introduction of direct oral anticoagulant (DOAC) and COVID-19 pandemic may change the incidence, mortality, and follow-up, especially in patients at high risk of bleeding.

Patients And Methods: We studied the use of anti-thrombotic therapy (AT) in patients with upper gastrointestinal bleeding for 5 years (January 2017-December 2021) including Covid-19 pandemic period (March 2020-December 2021).

Decrease of glutathione peroxidase in arrhythmic cardiac pathology in young individuals and its therapeutic implications.

Glutathione peroxidase (GPx), as an antioxidant enzyme, is involved in the regulation of processes that cause cellular oxidative stress, with implications in various pathologies. The aim of the present study was to evaluate GPx variations in patients with arrhythmic, non-structural cardiac disorders. The research was performed on 120 patients, with a mean age of 33 years old, divided into 3 equal groups, of which 2 groups included patients with cardiac arrhythmias, the first group, associated with dyslipidemia and the second one, without dyslipidemia, and a control group consisting of healthy individuals.

Variation of Total Antioxidant Activity in Young People with Non-Lesional Cardiac Arrhythmias.

Unlabelled: Total antioxidant activity status (TAS) represents the body's response to oxidative stress, important in the pathogenic assessment of oxidations.

Aim: To determine TAS variations in young subjects, with non-lesional cardiac arrhythmias, with/without dyslipidemia and to assess the risk of lipid oxidation.

Patients And Methods: The research was performed on 120 young subjects (mean age 33 years), with various types of cardiac arrhythmias, on normal heart, without co-existing lesions.

Visceral and tissular reactivity in acute heart failure due to supraventricular tachyarrhythmia in a young patient.

Observation of major pathological alterations in a young person involves etiological and clinical justifications, in order to properly assess, treat and control these conditions. The aim of this paper is to present severe, acute pathological lesions, installed in a young person, secondary to hypodiastolic heart failure, due to persistent supraventricular tachyarrhythmia, triggered by a post-traumatic external stimulus, with complete remission post-electrical conversion. Pathological and clinical modification are revealed, in a young person, shortly after a minor thoracic trauma, in the absence of traumatic injury but with high-frequency palpitations onset and progressive installation of vascular, visceral and interstitial stasis modifications, as well as of vascular and tissular hypoperfusion with reactive vasoconstriction.

Correlations between endothelial cell markers CD31, CD34 and CD105 in colorectal carcinoma.

Purpose: Colorectal carcinoma is an important cause of mortality worldwide. The fact that tumor growth is dependent on angiogenesis has supported researches for new prognostic parameters and the development of novel therapeutic strategies. Accordingly, we sought to evaluate angiogenesis quantitatively by assessing microvessel density in colorectal cancer.

Analysis of prognostic factors in colorectal carcinoma.

Unlabelled: Colorectal cancer is one of the most common malignancies in development countries. The purpose of this study was to analyze the epidemiologic profiles of the disease, to examine the results of survival at five years after diagnosis and how it was influenced by pathological aspects.

Material And Methods: In collaboration with Oncologic Clinic all colorectal cancer diagnosed from January 2002 to December 2006 were included in the study.
