oxalis macrantha/necrosis

We studied the combination of tumor necrosis factor (TNF) and paclitaxel. Our aim was to determine whether TNF increases the antitumor efficacy of paclitaxel and if so whether the increase is mediated through the enhancement of apoptosis induction by paclitaxel. Mice bearing 6 mm MCa-K or MCa-4

OBJECTIVE Necrosis is the most common morphologic alteration found in tumors and surrounding normal tissues after radiation therapy or chemotherapy. Accurate measurement of necrosis may provide an early indication of treatment efficacy or associated toxicity. The purpose of this report is to

Tumor necrosis and oxygen status were investigated as a function of tumor size in three syngeneic murine carcinomas, MCa-4, OCa-I, and SCC-VII, in C3Hf/Kam mice. Tumor necrosis was estimated histologically, and tumor oxygenation determined by direct polarographic histography. As tumor volume

Inhibition of the necrotizing hyaluronidase, phospholipase A2 and protease enzymes in four snake venoms by crude water and ethanol extracts of 88 plant species used against snakebites in traditional Chinese medicine was measured. High-resolution hyaluronidase inhibition profiles were constructed for

Osteochondritis dissecans (OCD) lesions of the knee are a significant source of pain and disability. Although the pathologic process for this condition remains poorly understood, histologic studies suggest vascular insufficiency of the subchondral bone may be the underlying cause for focal necrosis

The farnesoid X receptor (FXR) is a ligand-activated transcription factor that plays important roles in regulating bile acid homeostasis. The aim of the present study was to investigate the effects of obeticholic acid (OCA), a novel synthetic FXR agonist, carbon tetrachloride (CCl4)-induced acute

Rumex acetosa L., common name sorrel (in Brazil, azedinha), is an herb from Europe and Asia commonly used either as a vegetable or a medicinal plant (1). No pathogen has been recorded on this plant species in Brazil, where it has been promoted as an alternative vegetable crop. During a routine

Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) holds great potential as an anticancer drug, since it induces selective cell death in cancer cells but not in normal ones. However, cancer cells often acquire resistance to TRAIL, which hinders its clinical efficacy. We previously

Cholangiocarcinoma (CCA) is an aggressive cancer with high resistance to chemotherapeutics. CCA is enriched in cancer stem cells, which correlate with aggressiveness and prognosis. FXR, a member of the metabolic nuclear receptor family, is markedly down-regulated in human CCA. Our aim was to

Diabetic cardiomyopathy (DCM) is one of the major cardiac complications in diabetic patients and a major reason for the death of diabetic patients. Obeticholic acid (OCA) is a semi-synthetic bile acid analogue. The objective of the present study was to investigate the possible cardio-protective

Despite an intensive search, few water-soluble paclitaxel derivatives have been shown to have a therapeutic index superior to paclitaxel itself. We now report a water-soluble poly(L-glutamic acid)-paclitaxel conjugate (PG-TXL) that produces striking antitumor effects with diminished toxicity. A

BACKGROUND Cholestasis, as a main manifestation, induces liver injury during sepsis. The farnesoid X receptor (FXR) plays an important role in regulating bile acid homeostasis. Whether FXR activation by its agonist obeticholic acid (OCA) is contributed to improve sepsis-induced liver injury remains

OBJECTIVE To compare the biocompatibility of ethyl-cyanoacrylate (ECA) and octylcyanoacrylate (OCA) wound closures to sutures in rat skin. METHODS Twenty-four male Wistar rats were subjected to three incisions which were closed using ECA, OCA or sutures . Rats were divided into four groups which

This study examines the intraperitoneal behavior of two cyanoacrylate tissue adhesives: Ifabond® and a new, non-marketed octyl cyanoacrylate adhesive (OCA) used for the intraperitoneal fixation of a laminar expanded polytetrafluoroethylene (ePTFE) mesh. In 36 New Zealand White rabbits, 3 × 3 cm (n =
