adenotonsillar hypertrophy and obstructive sleep disordered breathing can lead to attention deficit/hyperactivity disorder (adhd). the purpose of this study was to evaluate effect of adenotonsillectomy on improvement of adhd symptoms in a quasi-experimental (before and after) study. the efficacy of adenotonsillectomy on improvement of adhd symptoms of 35 children aged 5-12 years with adenotonsi...

The nail unit is a dynamic complex which forms an important part of the integument. This complex consists of the nail matrix (NM), nail bed (NB), hyponychium, nail fold (NF) and the nail plate (NP). Cells of the nail matrix, under the protection of the proximal nail fold mature and keratinised to form the NP. The NM contributes to the most portion of the NP while about 10-15% is produced by the...

White superficial onychomycosis is less common than distal subungual onychomycosis and occurs when certain fungi invade the superficial layers of the nail plate directly. Later, the infection may move through the nail plate to infect the cornified layer of the nail bed and hyponychium. It can be recognized by the presence of welldelineated opaque “white islands” on the external nail plate, whic...

Background and Aims: Cardiac hypertrophy is a compensatory augmentation response of the heart due to pressure overload that can lead to heart failure. Carvacrol is considered as the major compound of many plants, that possesses strong antioxidant properties. The present study aimed to evaluate effect of carvacrol on catalase activity and mRNA expression following left ventricular hypertrop...

buckwheat rutin has been found to be able to inhibit angiotensin ii (angii) - induced hypertrophy in cultured neonatal rat cardiomyocytes, but the mechanism remains uncertain. in this study, myocardial hypertrophy model was made by adding angii to the medium of cardiac myocytes of neonatal rats, meanwhile, different concentrations of buckwheat rutin were applied to observe their effects. intrac...

background: it has been well documented that left ventricular hypertrophy (lvh) is an independent factor for cardiac death in children. the epidemiologic information reveals that there is a very high prevalence of lvh in children with chronic renal failure (crf). the purpose of this study was to evaluate the existence of left ventricular hypertrophy, its severity and other cardiac abnormalities...

background and aims: there has been scant information concerning antihypertrophic effects of vitamin d specifically on its cellular and molecular mechanisms. sirtuin 1 (sirt1) is regarded as a key deacetylase enzyme in cardiomyocytes which applies potential cardioprotective effects by functional regulation of different proteins. this study aimed to evaluate the effects of 1, 25-dihydroxyvitamin...

Background: Hypertension induces cardiac hypertrophy. Oxidative stress plays an important role in the pathogenesis of hypertension induced cardiac hypertrophy. Exercise and Quercetin (as activators of Sirtuins) reduce oxidative stress. The aim of this study was to investigate the effect of high-intensity interval training (HIIT) with Quercetin supplement on oxidative stress and level of concent...

Objective(s): To determine the effects of triiodothyronine (T3) intracoronary perfusion in isolated hearts and short-term administration in rats on the left ventricular (LV) phosphorylation patterns of Akt and ERK1/2. Materials and Methods: Cardiodynamic and hemodynamic parameters were evaluated in Langendorff–perfused hearts. Left ventr...
