Skin Tears Preventable With a Gentle Approach: A Case Series.

Skin tears are a major problem for patients and the health care professionals who treat them. Although opinions on their prevalence differ, it is estimated that they are encountered more frequently than pressure sores but are overlooked. Recommendations based on strong evidence were presented for the prevention and treatment of skin tears as classified by the International Skin Tear Advisory Panel.

Are serum nitric oxide and vascular endothelial growth factor levels affected by packed red blood cell transfusions?

Background: Nitric oxide (NO) and vascular endothelial growth factor (VEGF) are important mediators for hemodynamics and angiogenesis in the body. NO coming from endothelial cells and red blood cells is particularly effective in hypoxic vasodilation. VEGF has known effects on the induction of NO synthesis and is also known to be affected by blood product transfusions.

The long-term effects of progesterone-only contraceptives on endometrium and ovary in rats.

Design: Prospective controlled study.

Setting: University hospital.

African dust-laden atmospheric conditions activate the trigeminovascular system.

It has been recently noticed that dust originating from deserts can be transported to other continents by the atmosphere and has an adverse effect on public health, such as increased asthma attacks. Dust originating from the Saharan Desert could initiate a series of reactions upon contact with cloud water and results in the formation of reduced iron (Fe(2+)), oxalate and various basic amino acids. We aimed to evaluate whether the simulation of Saharan dust-containing atmospheric conditions could trigger the trigeminovascular system.

Is oxidative damage in operation in patients with hereditary spastic paraparesis?

Oxidative stress resulting from increased free radical production and/or defects in antioxidant defences may be the cause of various neurodegenerative disorders. In this study, the roles of oxygen free radicals, nitric oxide, superoxide dismutase, vitamin E and vitamin C were investigated in pure and complicated hereditary spastic paraparesis (HSP) patients. The results showed that plasma SOD, vitamin E and nitric oxide levels were significantly low in HSP patients.

Maternal and umbilical venous adrenomedullin and nitric oxide levels in intrauterine growth restriction.

Objective: To verify whether adrenomedullin (AM) and nitric oxide (NO) concentrations are changed in the maternal and fetal circulation in pregnancies complicated by intrauterine growth restriction (IUGR) compared to normal pregnancies, and to determine any relationship between them.

Methods: Forty-six small for gestational age (SGA) and 34 appropriate for gestational age (AGA) infants were included in the study. Umbilical and maternal venous AM and NO concentrations were determined.

Effect of montelukast on symptoms and exhaled nitric oxide levels in 7- to 14-year-old children with seasonal allergic rhinitis.

Background: Cysteinyl leukotrienes have been found to exert potent inflammatory effects in the upper airways and play a fundamental role in the pathogenesis of allergic rhinitis. Previous studies have reported increased levels of exhaled nitric oxide (eNO) in patients with allergic rhinitis without asthma symptoms.

Objective: To investigate the role of treatment with montelukast on symptoms, eNO levels, and peripheral eosinophil counts of children with seasonal allergic rhinitis during pollen season.

Effects of different resistance exercise protocols on nitric oxide, lipid peroxidation and creatine kinase activity in sedentary males.

The purpose of this study was to determine the changes of oxidative response and exercise-induced muscle damage after two different resistance exercise protocols. Whether training with low or high intensity resistance programs cause alterations in the activities of lipid peroxidation, nitric oxide (NOx), and creatine kinase (CK) activity in human plasma was investigated. Twenty untrained males participated into this study.

Antioxidant effect of vitamin E in the treatment of nutritional iron deficiency anemia.

Oxidant status and antioxidants play important roles in anemias. The present study was conducted to investigate the oxidant-antioxidant status in iron deficiency anemia (IDA), and to evaluate the antioxidant effect of vitamin E in IDA treatment. Ten patients with IDA aged nine months were given only iron treatment, whereas another 10 patients were administered both iron and vitamin E.

Prevention of doxorubicin-induced cardiotoxicity by melatonin.

Anthracyclines, such as doxorubicin and daunorubicin, are highly effective anticancer agents. Cardiotoxicity made by these agents develops as a complication of the cancer chemotherapy. Melatonin, the chief secretory product of the pineal gland, was recently found to be a free radical scavenger and antioxidant.

Evaluation of oxidant stress in Wilson's disease and non-Wilsonian chronic liver disease in childhood.

Background/aims: Oxygen free radicals have an important role in the pathogenesis of acute and chronic liver disease. Free radical formation and oxidative damage, probably mediated with copper accumulation, are important in Wilson's disease pathogenesis. This study was performed to determine if accumulating copper in Wilson's disease is a cause of further oxidant stress compared to non-Wilsonian liver disease.

The effect of L-NAME administrations after oral mucosal incision on wound NO level in rabbit.

The aim of the current study was to comparatively investigate the effect of inhibition of nitric oxide (NO) production by N-nitro-L-arginine methyl ester (L-NAME), an isoform non-specific inhibitor of nitric oxide synthase (NOS), after oral mucosal incision on wound tissue NO levels. A standard incision was applied to the oral mucosa of rabbits.

Effects of diethylstilbestrol in human lymphocytes in vitro: a dose and time-dependent study on genotoxic, cytotoxic and apoptotic effects.

Most of the biological, chemical or physical agents that cause cell death in certain doses and time of exposure may induce either apoptosis or necrosis. This study explores in what ways the genotoxic, cytotoxic and apoptotic effects of diethylstilbestrol (DES), a chemical agent currently used in the treatment of various types of cancer, on the human lymphocytes depend upon the dose and the exposure time. For this purpose, firstly it aims to determine in what dosages and durations of DES treatment, genotoxicity and cytotoxicity in human lymphocytes occur in vitro.

Plasma and urine nitric oxide levels in healthy Turkish children.

Nitric oxide (NO) is an important messenger molecule with a wide range of actions in virtually all cell systems and organs. In kidneys it participates in glomerular and medullary hemodynamics, tubuloglomerular feed-back, renin secretion, and extracellular fluid balance. Although the role of NO in regulating renal function in adults is well-established, it has recently been suggested that NO has a more critical role in maintaining basal renal blood flow and glomerular filtration rate (GFR) in the developing kidney.

Increased serum nitrite/nitrate (NOx) and malondialdehyde (MDA) levels during alcohol withdrawal in alcoholic patients.

Serum nitrite/nitrate (NOx) and malondialdehyde (MDA) levels of 40 male alcoholic patients and 14 healthy male controls were investigated. Severity of alcohol withdrawal in alcoholic patients was evaluated by using the Clinical Institute Withdrawal Assessment for Alcohol (CIWA-Ar) scale just before taking the blood samples. NOx levels in serum samples were determined based on the reduction of nitrate to nitrite by vanadium chloride.
