OBJECTIVES To compare cardiac troponin T, myoglobin, CK, CKMB activity, CKMB mass and the initial electrocardiogram in the early diagnosis of myocardial infarction in the emergency department. Methods-Biochemical markers were measured at presentation in patients with a possible diagnosis of acute myocardial infarction. Based on the clinical notes, patients were grouped as "definite myocardial i...

Hypoxia-ischemia constitutes a risk in infants by altering cerebral blood flow regulatory mechanisms and causing loss of cerebral vascular auto-regulation. Hypotension, cerebral ischemia, and reperfusion are the main events involved in vascular auto-regulation leading to cell death and tissue damage. These dramatic phenomena represent a common repertoire in infants complicated by perinatal acut...

Aim of the present study to evaluate the Chronic Obstructive Pulmonary Disease (COPD), also known as chronic obstructive airway disease (COAD), is a group of diseases characterized by the pathological limitation of airflow in the airway that is not fully reversible. Emphysema is a multifactorial disorder and involves interplay of genetic, inflammatory and oxidative factors during its progressio...

ADHD (attention hyperactivity disorder) is a polygenetic disorder with various candidate genes. At this time, more than thirty dopaminergic, noradrenergic, serotonergic and GABA-ergic genes are known. The research of only some candidate genes (DRD4, DAT, DRD5, DBH, 5HTT, HTR1B and SNAP25) brought relatively consistent results confirming the heredity of ADHD syndromes. The results of research of...

A chemical compound, whether of natural or of synthetic origin, brings about a toxicological effect when its dose is high enough or the duration of exposure is sufficient to cause an alteration in the normal homeostasis of body fluids and tissues. Therefore, the right dose differentiates a toxicant from a remedy. The body detoxifies drugs and other chemical compounds through key organs such as ...

Preterm delivery is the leading cause of perinatal morbidity and mortality worldwide. Despite a great deal of research into this disease, we still do not understand its pathophysiology. Our treatments for this disease are only marginally effective. Biochemical markers were developed with the hope of giving us new tools to prevent preterm deliveries. Specifically the hope was that they could pre...

Worldwide, oral carcinoma is one of the most prevalent cancers and is one of the 10 most common causes of death. If oral cancers and cancers of nasopharynx, pharynx, larynx, sinus and salivary glands are combined, these sites represent more than 5% of total body cancers. Approximately 95% of oral squamous cell carcinoma (OSCC) occurs in people older than 40 years. However OSCC at a young age ha...
