Multifactorial intervention for diabetes control among older users of insulin

ABSTRACT OBJECTIVE: To evaluate if the closer follow-up with the supply of insulin pens and the measurement of capillary blood glucose improve the management of older patients with type 2 diabetes without adequate glycemic control despite extensive therapy. METHODS: This is a prospective, non-randomize...

Erradicación de Helicobacter pylori con terapia triple estándar de primera línea

Cienc. tecnol. salud; 5 (1), 2018
La infección por Helicobacter pylori es una de las infecciones crónicas más comunes a nivel mundial y causa importante de enfermedad péptica y cáncer gástrico. Infecta al 50% de la población adulta con mayor prevalencia en América Central/Sur y Asia y al menos dos veces mayor en poblaciones con a...

Exosomes promote cetuximab resistance via the PTEN/Akt pathway in colon cancer cells

Braz. j. med. biol. res; 51 (1), 2018
Cetuximab is widely used in patients with metastatic colon cancer expressing wildtype KRAS. However, acquired drug resistance limits its clinical efficacy. Exosomes are nanosized vesicles secreted by various cell types. Tumor cell-derived exosomes participate in many biological processes, including tumor...

Agonistic activity of tamoxifen, a selective estrogen-receptor modulator (SERM), on arthritic ovariectomized mice

Braz. j. med. biol. res; 51 (1), 2018
Arthritis is positively associated with the decline of sex hormones, especially estrogen. Tamoxifen (TMX) is a selective estrogen receptor modulator, possessing agonist or antagonistic activity in different tissues. Thus, the objective of this study was to investigate the effect of TMX on the zymosan-ind...

Behavioral cross-sensitization between testosterone and fenproporex in adolescent and adult rats

Braz. j. med. biol. res; 51 (1), 2018
The abuse of psychoactive drugs is considered a global health problem. During the last years, a relevant number of studies have investigated the relationship between anabolic-androgenic steroids (AAS) and other psychoactive drugs. AAS, such as testosterone, can cause a dependence syndrome that shares man...

Endothelin-1 receptor antagonists protect the kidney against the nephrotoxicity induced by cyclosporine-A in normotensive and hypertensive rats

Braz. j. med. biol. res; 51 (2), 2018
Cyclosporin-A (CsA) is an immunosuppressant associated with acute kidney injury and chronic kidney disease. Nephrotoxicity associated with CsA involves the increase in afferent and efferent arteriole resistance, decreased renal blood flow (RBF) and glomerular filtration. The aim of this study was to eval...

Effectiveness of preoperative decolonization with nasal povidone iodine in Chinese patients undergoing elective orthopedic surgery: a prospective cross-sectional study

Braz. j. med. biol. res; 51 (2), 2018
Staphylococcus aureus colonization in the nares of patients undergoing elective orthopedic surgery increases the potential risk of surgical site infections. Methicillin-resistant S. aureus (MRSA) has gained recognition as a pathogen that is no longer only just a hospital-acquired pathogen. Patients posit...

Granulocyte colony-stimulating factor combined with Methylprednisolone improves functional outcomes in rats with experimental acute spinal cord injury

Clinics; 73 (), 2018
OBJECTIVES: To evaluate the effects of combined treatment with granulocyte colony-stimulating factor (G-CSF) and methylprednisolone in rats subjected to experimental spinal cord injury. METHODS: Forty Wistar rats received a moderate spinal cord injury and were divided into four groups: control (no treat...

Resting spontaneous baroreflex sensitivity and cardiac autonomic control in anabolic androgenic steroid users

Clinics; 73 (), 2018
OBJECTIVES: Misuse of anabolic androgenic steroids in athletes is a strategy used to enhance strength and skeletal muscle hypertrophy. However, its abuse leads to an imbalance in muscle sympathetic nerve activity, increased vascular resistance, and increased blood pressure. However, the mechanisms underl...

Berberine ameliorates diabetic nephropathy by inhibiting TLR4/NF-κB pathway

Biol. Res; 51 (), 2018
BACKGROUND: Diabetic nephropathy (DN) is the leading cause of end-stage renal failure, contributing to severe morbidity and mortality in diabetic patients. Berberine (BBR) has been well characterized to exert renoprotective effects in DN progression. However, the action mechanism of BBR in DN remains to ...
