STUDY DESIGN The authors examined a case series of patients under the age of 18 years treated for lumbar intervertebral disc herniation. OBJECTIVES To evaluate postoperative and long-term results of surgery in patients younger than 18 years. SUMMARY OF BACKGROUND DATA There are only a few series, with controversial results, available on the surgical(More)
Conjugated linoleic acid (CLA) is a naturally occurring fatty acid, which has been shown to exert beneficial effects against breast carcinogenesis. It has been reported that CLA could modulate cellular proliferation and differentiation through the activation of peroxisome proliferator-activated receptors (PPARs). Among different PPAR isotypes, PPAR gamma is(More)
Idiopathic analbuminemia was fortuitously detected in a 30-year-old Italian woman. No associated disease condition could be revealed in this patient, the only consistent finding being a slight tendency to develop ankle edema. Asthenia and a moderate hypotension were also recorded. Trace amounts (5.2 mg/100 ml) of serum albumin were determined by(More)
Liver fibrogenesis is a dynamic and highly integrated molecular, tissue and cellular process, potentially reversible, that drives the progression of chronic liver diseases (CLD) towards liver cirrhosis and hepatic failure. Hepatic myofibroblasts (MFs), the pro-fibrogenic effector cells, originate mainly from activation of hepatic stellate cells and portal(More)
BACKGROUND/AIMS Interferon alpha provides benefit in only a limited number of patients with chronic anti-HBe-positive hepatitis B. The aim of this study was to verify the long-term efficacy of lamivudine treatment of these patients and the incidence of lamivudine-resistant hepatitis B virus mutants. METHODS Fifteen consecutive patients with chronic(More)
Both n-6 and n-3 polyunsaturated fatty acids are dietary fats important for cell function, being involved in several physiologic and pathologic processes, such as tumorigenesis. Linoleic acid and conjugated linoleic acid, its geometrical and positional stereoisomer, were tested on several human tumor cell lines originating from different tissues and with(More)
Costunolide is an active sesquiterpene lactone of medicinal herbs with anti-inflammatory and potential anti-cancer activity. Nevertheless, the pharmacological pathways of costunolide have not yet been fully elucidated. In this study we showed that costunolide exerts a dose-dependent antiproliferative activity in the human breast cancer MCF-7 cells. In(More)
Solid Lipid Nanospheres (SLN) are colloidal therapeutic systems proposed for several administration routes and obtained by dispersing warm microemulsions in cold water. SLN as carriers of doxorubicin and paclitaxel have been previously studied. In this study, the cellular uptake of SLN and the cytotoxicity of doxorubicin and paclitaxel incorporated into SLN(More)
We investigated the molecular mechanisms involved in the anti-proliferative activity exerted by conjugated linoleic acid (CLA) on the estrogen unresponsive MDA-MB-231 human breast cancer cell line. The effects on cell proliferation, cell cycle progression and induction of apoptosis were examined. CLA caused the reduction of cell proliferation along with the(More)
This study demonstrates how the potentiating effects of E2 on insulin signaling in ER-positive breast cancer cells are consequent to an enhanced IRS-1 expression [corrected]. It induces an increase of both PI-3K/AKT and ERK1/2 activities. A direct action of E2 in the regulating mouse IRS-1 gene is also investigated in both Chinese hamster ovary and MCF-7(More)
