Can atypical response in endothelial dysfunction-related genes and microRNAs arise from low hydrogen peroxide exposure?

Objective: Vascular endothelium is a tissue in which several vasoactive substances are produced and secreted. Reactive oxygen species can cause endothelial dysfunction (ED). miRNAs can be implicated in the oxidative stress-related ED during vascular disease pathogeneses.

Anti-proliferative effects of beta-blocker propranolol on human lung cancer and noncancer cells.

Objective: Propranolol (PRO) has been recently discovered to possess anti-tumorigenic effects in cancer patients. So, we aimed to enlighten the in vitro effects of propranolol in A549 lung cancer cells and BEAS2B nontumoral lung cells.

Methods: The gene expression levels of apoptotic proteins; caspases 3, 8, and 9 (CASP3, 8, 9), apoptosis inducing factor (AIF), and DNA damage inducible transcript 3 (DDIT3) and cell cycle regulatory proteins; WEE1 G2 checkpoint kinase (WEE1) and cyclin dependent kinase inhibitor 1A (CDKN1A) were analyzed with quantitative reverse-transcription PCR to assess the effect of PRO on A549 tumor and BEAS2B nontumoral cells.

Behavioral and Cognitive Consequences of Obesity in Parents and Offspring in Female and Male Rats: Implications of Neuroinflammation and Neuromodulation.

Obesity is a rapidly growing public health concern that can create a family-wise burden. This study was aimed to investigate behavioral, cognitive, neuroinflammatory, and neuromodulatory consequences of the diet and parental obesity. Female and male Wistar albino rats were fed on either an obesogenic or standard diet for 12 weeks, beginning with weaning.

Genetic variations of renin-angiotensin and fibrinolytic systems and susceptibility to coronary artery disease: a population genetics perspective.

Background: Genetic predisposition is an important risk factor in coronary artery disease (CAD).This study was conducted to determine the polymorphism frequencies of the plasminogen activator inhibitor-1(PAI-1) gene 4G/5G, angiotensin-converting enzyme (ACE) gene I/D, and angiotensin II type 1 receptor (AT1) gene A1166C genotypes and to examine the role of these polymorphisms in CAD.

Methods: Genomic DNAs obtained from 260 subjects (130 CAD patients and 130 control) were used in the study.

[Investigation of Polymerase Chain Reaction Method in Patients with Suspected Chronic Cutaneous Leishmania of Negative Microscopy].

Leishmaniasis is a parasitic disease that is transmitted to humans by the bites of infected female phlebotomine sandflies. In the diagnosis of cutaneous leishmaniasis (CL), in the smear samples, the demonstration of the parasite by microscope remains a gold standard method. However, it becomes difficult to diagnose the parasite since the number of amastigotes in chronic cases with a lesion of one year or longer is very low.

Suppressive effect of Rho-kinase inhibitors Y-27632 and fasudil on spike-and-wave discharges in genetic absence epilepsy rats from Strasbourg (GAERS).

Rho/Rho-kinase (ROCK) signaling contributes to neuroinflammation, epileptogenesis, and seizures in convulsive-type epilepsies. However, this pathway has not been investigated in absence epilepsy. We investigated RhoA activity in genetic absence epilepsy rats from Strasburg (GAERS) and the effects of ROCK inhibitors Y-27632 and fasudil on spike-and-wave discharges (SWDs) of GAERS.

Role of ACE I/D gene polymorphisms on the effect of ramipril in inflammatory response and myocardial injury in patients undergoing coronary artery bypass grafts.

Background: Angiotensin-converting enzyme (ACE) inhibitors block angiotensin II formation and release bradykinin, which is effective in the regulation of oxidoinflammatory injury. Some reports denote alterations in the effectiveness of ACE inhibitors in association with ACE insertion/deletion (I/D) gene polymorphisms. This study investigates the effects of ramipril on the oxidoinflammatory cytokines (IL-6, IL-8, TNF-alpha) and TnT (myocardial injury marker) and their alteration in association with ACE I/D gene polymorphisms.

Investigation of relationship between IL-6 gene variants and hypertension in Turkish population.

Hypertension (HT) is a common and life threating health problem worldwide leading to stroke, heart attack and renal failure. It is characterized by elevated blood pressure forced heart load. Human interleukin-6 (IL-6) and C- reactive protein (CRP) are known to be involved in inflammatory processes.

Is there any genetic predisposition of MMP-9 gene C1562T and MTHFR gene C677T polymorphisms with essential hypertension?

The current study was conducted to determine whether there is a relation between hypertension and two different polymorphisms, including C1562T of the Matrix metalloproteinase-9 (MMP-9) gene and C677T of the methylenetetrahydrofolate reductase (MTHFR) gene. Genomic DNA obtained from 224 persons (125 patients with hypertension and 99 healthy controls) were used in the study. Polymorphisms were determined by using polymerase chain reaction-restriction fragment length polymorphism and electrophoresis.

Prevalence of beta-thalassemia trait and abnormal hemoglobins in the province of Adıyaman, Turkey.

Background/aims: Thalassemia is one of the most common hereditary disorders in Turkey. The aim of this study was to determine the prevalence of the beta-thalassemia trait and abnormal hemoglobins in the province of Adıyaman in Turkey.

Methods: The study included 3571 high school students of both sexes; aged 12-22 (mean 16.

Is the dopamine D3 receptor mRNA on blood lymphocytes help to for identification and subtyping of schizophrenia?

Schizophrenia is one of the neuropathological disorders, which are associated with dopamine and its receptors. In recent years, it has been shown that mRNA of D3, D4 and D5 dopamine receptor (DRD3, DRD4, DRD5) subtypes is expressed in human peripheral blood lymphocytes (PBL). A total 55 schizophrenic patients and 51 healthy subjects were included in the study to investigate the levels of DRD3 mRNA in PBL of schizophrenic patients and whether DRD3 mRNA level in PBL can serve as peripheral marker for schizophrenia.
