The Ehrlich tumor is a mammary adenocarcinoma of mice that can be developed in solid and ascitic forms depending on its administration in tissues or cavities, respectively. The present study investigates whether the subcutaneous plantar administration of the Ehrlich tumor cells induces pain-like behavior and initial pharmacological susceptibility(More)
The Von Hippel-Lindau (VHL) disease is an autosomal dominant disorder characterized by the predisposition for multiple tumors caused by germline mutations in the tumor suppressor gene VHL. This disease is associated with a high morbidity and mortality and presents a variable expression, with different phenotypes from family to family, affecting different(More)
Acute kidney injury (AKI) represents a complex clinical condition associated with significant morbidity and mortality. Approximately, 19-33% AKI episodes in hospitalized patients are related to drug-induced nephrotoxicity. Although, considered safe, non-steroidal anti-inflammatory drugs such as diclofenac have received special attention in the past years(More)
Titanium dioxide (TiO2) is a common component of orthopedic prosthesis. However, prosthesis wear releases TiO2, which induces inflammation and osteolysis in peri-prosthetic tissues. Quercetin is a flavonoid widely present in human diet, which presents biological activities such as antinociceptive, anti-inflammatory and antioxidant effects. Therefore, the(More)
Adrenocortical tumours (ACT), which include adenomas, carcinomas and adrenal hyperplasia, may be associated with genetic syndromes, such as Li-Fraumeni syndrome, Beckwith-Wiedemann syndrome, multiple endocrine neoplasia type 1, familial adenomatous polyposis and Carney complex. Genetic defects have been found to be responsible for the disease in most of(More)
Cancer pain directly affects the patient's quality of life. We have previously demonstrated that the subcutaneous administration of the mammary adenocarcinoma known as Ehrlich tumor induces pain in mice. Several studies have shown that the flavonoid quercetin presents important biological effects, including anti-inflammatory, antioxidant, analgesic, and(More)
5-Lipoxygenase (5-LO) converts arachidonic acid into leukotrienes (LTs) and is involved in inflammation. At present, the participation of 5-LO in acetaminophen (APAP)-induced hepatotoxicity and liver damage has not been addressed. 5-LO deficient (5-LO⁻/⁻) mice and background wild type mice were challenged with APAP (0.3-6 g/kg) or saline. The lethality,(More)
Dear Editor, This is a case report of a male patient, 47 years of age, with a one-year history of an asymptomatic nodular mass on the left hallux. The patient reported gradual growth, with a rapid increase in size over the past two months. The dermatological examination revealed a firm, painless mass, measuring approximately 5 x 4 cm, on the left hallux(More)
Subcutaneous phaeohyphomycosis is an infection caused by dematiaceous fungi which mainly affects immunosuppressed patients. We report a case of subcutaneous phaeohyphomycosis on the back of the left hand in a kidney transplant patient who had been taking prednisone, tacrolimus, and azathioprine daily for 3 years.
Purpose To investigate the effect of naringenin eye drops in corneal neovascularization induced by alkali (1 N NaOH) burn in mice. Methods Corneal neovascularization in the right eye of male Swiss mice was induced by alkali. Treatment with naringenin eye drops (0.08-80 μg; 8 μL of 0.01-10 g/L solution) or vehicle (saline) started 2 days before corneal(More)
