Participation of the arcRACME protein in self-activation of the arc operon located in the arginine catabolism mobile element in pandemic clone USA300

Mem. Inst. Oswaldo Cruz; 112 (7), 2017
ABSTRACT Staphylococcus aureus pandemic clone USA300 has, in addition to its constitutive arginine catabolism (arc) gene cluster, an arginine catabolism mobile element (ACME) carrying another such cluster, which gives this clone advantages in colonisation and infection. Gene arcR, which encodes an oxygen...

Association between the p53 arginine/arginine homozygous genotype at codon 72 and human papillomavirus E6/E7 mRNA expression

Braz. j. infect. dis; 21 (3), 2017
ABSTRACT Objective: To evaluate the association between p53 polymorphisms and human papillomavirus (HPV) E6/E7 mRNA expression. Methods: We analyzed 175 cervical samples from women aged 16-69 years old who were tested for HPV E6/E7 mRNA expression (NucliSENS® EasyQ® HPV). The samples were divided int...

Visceral adiposity index and triglyceride/high-density lipoprotein cholesterol ratio in hypogonadism

ABSTRACT Background Cardiometabolic risk is high in patients with hypogonadism. Visceral adiposity index (VAI) and triglyceride/high-density lipoprotein cholesterol (TG/HDL-C) ratio are the practical markers of atherosclerosis and insulin resistance and independent predictors of cardiaovascular risk. T...

In vitro and in situ evaluation of the effects of high-fluoride and arginine-based toothpastes to control root caries

The focus of our studies has been the root substrate dentin, once root caries prevalence has been reported as increasing in part due to people living longer and maintaining their natural teeth into old age. Furthermore, this condition is highly prevalent in patients undergoing head-and-neck radiotherapy ...

Efeitos de osmólitos na L- asparaginase II de Erwinia chrysanthemi em meio aquoso

A L- asparaginase é uma enzima aplicada no tratamento de Leucemia Linfoide Aguda, que atua na hidrólise da L- asparagina, privando a célula tumoral de um aminoácido essencial para o seu crescimento. A L- asparaginase, como outros biofármacos, deve ser estável, manter sua atividade específica e for...

Effect of S-methyl-l-thiocitrulline dihydrochloride on rat micturition reflex

Int. braz. j. urol; 42 (5), 2016
ABSTRACT Objective: To evaluate the effect of neuronal nitric oxide synthase on the striated urethral sphincter and the urinary bladder. Materials and Methods: A coaxial catheter was implanted in the proximal urethra and another one in the bladder of female rats, which were anesthetized with subcutaneo...

Nutritional supplementation with arginine protects radiation-induced effects. An experimental study

Acta cir. bras; 31 (10), 2016
ABSTRACT PURPOSE: To investigate the protective effect of L-arginine on the prostate (nonneoplasic) of rats with radiation-induced injury. METHODS: Twenty-nine Wistar rats, male adult, allocated into three groups: Control group (C) was not exposed to irradiation (n=10); Radiated group (R) had undergone...

Oral or topical administration of L-arginine changes the expression of TGF and iNOS and results in early wounds healing

Acta cir. bras; 31 (9), 2016
ABSTRACT PURPOSE: To evaluate the contribution of L-arginine oral or topical rout of administration in the surgical wound healing process. METHODS: L-arginine was orally or topically administrated to mice after a laparotomy model procedure. The wounds were analyzed to evaluate the granulation tissue by...

Nitric oxide and asymmetric dimethyl arginine (ADMA) levels in an experimental hydronephrotic kidney caused by unilateral partial ureteral obstruction

Int. braz. j. urol; 42 (3), 2016
ABSTRACT Aim Our aim is to measure asymmetric dimethyl arginine and nitric oxide levels in rats with induced unilateral acute ureteral obstruction to research the effects on the kidney. Material and Methods The study included 21 adolescent (average age 6 weeks) Sprague-Dawley male rats weighing betwe...

Therapeutic effects of ellagic acid on L-arginin induced acute pancreatitis

Acta cir. bras; 31 (6), 2016
ABSTRACT PURPOSE: To investigate the therapeutic effects of ellagic acid on L-arginin ınduced acute pancreatitis in rats. METHODS: Thirty-two were split into four groups. Group 1 (control) rats were performed only laparotomy, no drugs were administered. Group 2 (control+EA) rats were administered ...
