NATIONAL CURRENCY INSTABILITY

The concept related to currency stability includes internal currency stability as intern price stability, the money demand and supply stability and the stability of the interest rate. Also it includes external currency stability through exchange rate mechanism. The equilibrium of national economy is determined by the evolution of inflation and by the evolution of nominal exchange rate mechanism as an expression of external stability.monetary policies; financial crisis; currency stability

Laparoscopic versus open surgical treatment of umbilical hernia

Umbilical hernia is one of the types of ventral hernias of the abdominal wall and it represents the externalization of a part of the abdominal contents through a defect of the anterior abdominal wall located in the umbilical region. It is estimated that more than 20 million abdominal wall hernia surgeries are performed worldwide each year. The paper presents a retrospective study on the patients diagnosed with umbilical hernia and admitted to the First and Second Surgery Departments of the Sibiu County Emergency Clinical Hospital. The study includes 82 cases diagnosed with umbilical hernias over a period of 4 years, between 01.01.2017 and 31.12.2020. Open and laparoscopic surgical techniques are compared in terms of outcomes and postoperative complications. Most cases of umbilical hernia were within the age group 51-70 years, with a slightly higher incidence in males. Arterial hypertension and obesity were the most frequent comorbidities. The alloplastic, classic or laparoscopic procedure became the most widely used due to benefits such as: rapid socio-professional reintegration, short-term hospitalization and low incidence of relapses and postoperative complications. The current trend is for the IPOM laparoscopic procedure to become the gold standard in the treatment of umbilical hernias

The Role of PDGFs and PDGFRs in Colorectal Cancer

Introduction. Colorectal cancer (CRC) is an important cause of morbidity and mortality worldwide. Angiogenesis was reported as one important mechanism activated in colorectal carcinogenesis. Tumor microenvironment associated angiogenesis involves a large spectrum of signaling molecules and deciphering their role in colorectal carcinogenesis still represents a major challenge. The aim of our study is to point out the diagnosis and prediction role of PDGF family and their receptors in colorectal carcinogenesis. Material and Methods. A systematic search in Medline and PubMed for studies reporting the role of platelet-derived growth factors (PDGFs) and their receptors (PDGFRs) in tumor biology related to CRC was made. Results. PDGFs are important growth factors for normal tissue growth and division, with an important role in blood vessel formation. PDGFs/PDGFRs signaling pathway has been demonstrated to be involved in angiogenesis mainly by targeting pericytes and vascular smooth muscle cells. High levels of PDGF-BB were reported in CRC patients compared to those with adenomas, while elevated levels of PDGFR α/β in the stroma of CRC patients were correlated with invasion and metastasis. Moreover, PDGF-AB and PDGF-C were correlated with early diagnosis, cancer grading, and metastatic disease. Conclusions. Both PDGFs and PDGFRs families play an important role in colorectal carcinogenesis and could be considered to be investigated as useful biomarkers both for diagnosis and treatment of CRC

Exports -trends and impacts on Romania's economic growth process

Abstract. In the post-crisis period when domestic consumer demand had slumped, Romania and other European Union countries have tried to promote exports as an important engine of economic growth. In order to achieve this, some countries allowed a significant depreciation of their national currency so as to increase competitiveness, others turned to internal devaluations, to improvements of the exported product's technological intensity, to diversification of export destinations, etc., depending on the pre-crisis (initia

Monetary Policy Approaches Taking into Consideration the Current Economic Context

Questions of interest among monetary policy makers involves the identification and analysis of various relationships between macroeconomic variables. To analyze these variables and their interrelations it is necessary to build a macroeconomic model which is based on a vector autoregressive, and in which exogenous shocks have impact on the study variables. How exogenous variables affect the variables of interest represent the transmission mechanisms. Estimates of the transmission mechanism has been considered traditionally, one of the major objectives of many macroeconomic studies. Such empirical researchers have obtained two major conclusions: first, that the transmission mechanism varies over time and the second is that the exogenous shocks change over time. Modeling these variables can intercept all these variations? The conclusions of these models are sufficient for monetary policy makers

Exports – trends and impacts on Romania’s economic growth process

In the post-crisis period when domestic consumer demand had slumped, Romania and other European Union countries have tried to promote exports as an important engine of economic growth. In order to achieve this, some countries allowed a significant depreciation of their national currency so as to increase competitiveness, others turned to internal devaluations, to improvements of the exported product’s technological intensity, to diversification of export destinations, etc., depending on the pre-crisis (initial) structural conditions from which they had started. Our study aims to investigate how Romanian exports have changed in recent years, as well as the factors, both internal and external, that influence Romania’s export capacity, with the purpose of achieving economic recovery

Sustainability of public co-financing of investment projects with EU financial assistance in Romania

The public sector capacity of the EU Member States to access the European funds depends highly on the sustainability of their government budgets. According to the European Commission assessment, Romania is not facing a risk of fiscal stress in the short run. However the effects of the economic crisis and the vision with a predominantly social character regarding the public expenditures have contributed to the limitation of resources allocated for economic development. The low level of absorption of the European funds in Romania means implicit losses for the national economy, but a higher level could have been a cause for excessive budget deficit. In order to reduce the pressure on the state budget the government aims at being committed mainly in investment projects with EU financial assistance. This reflects the substitution of the state own financial resources with foreign funds, therefore the additionality effect initially wanted by the EU decreases. The paper evaluates the public investment effort in Romania under the Fiscal Pact limit on deficit and the conditionalities negotiated with IMF, as well as its effects on the economy and budget deficit

Exchange rate volatility effects on export competitiveness. Romanian Case

In this paper we determine and analyze the impact of the exchange rate variation over the international trade of Romania. We highlighted the sense of the relationship between exchange rate and exports or imports, but the intensity between the variables and the lags that characterize the interdependency between them. In the context of actual great imbalances in the global economy and other risks (financial, political or social) that drive to the decrease in aggregate demand on global level, we consider that external competitivity became one of the key variable for the economic growth in Romania like an integrated process in the European economy
