Possible role of alpha-lipoic acid in the treatment of peripheral nerve injuries
No full textAbstract Recent findings on the antioxidant effects of pretreatment with α-lipoic acid (α-LA) on the crush injury of rat sciatic nerve confirm the possible usefulness of α-LA administration in humans with peripheral nerve injuries. We discussed this issue in relation with our recent results in which the combined employment of α-LA and γ-linolenic acid with a rehabilitation program for six weeks reduced sensory symptoms and neuropathic pain in patients with compressive radiculopathy syndrome from disc-nerve root conflict in comparison with patients submitted to rehabilitation program alone for six weeks.</p
Cell-cycle specificity of sulforaphane-mediated apoptosis in Jurkat T-leukemia cells.
No full textSulforaphane (SFN) is an isothiocyanate that is present in widely consumed vegetables. Previous studies have shown that SFN is effective in preventing carcinogenesis induced by carcinogens in rodents. Recently it was found that SFN could also inhibit cell proliferation and induce apoptosis in several tumor cell lines. In the present study, the possible cell-cycle specificity of SFN-mediated apoptosis was investigated. Cells were synchronized by thymidine block. Analysis of the cell-cycle and apoptosis induction was performed using flow cytometry. Flow cytometric assessment of the extent of apoptosis in cells synchronized by thymidine block revealed that cells were most sensitive to SFN in the G1 phase, less sensitive in the G2/M phase and least sensitive during the S phase. These findings suggest that cell vulnerability to SFN-mediated apoptosis is subject to regulation by cell-cycle-dependent mechanisms

Sulforaphane increases the efficacy of doxorubicin in mouse fibroblasts characterized by p53 mutations.
No full textOne novel strategy for increasing cancer chemotherapy efficacy and reversing chemoresistance involves co-administration of natural chemopreventive compounds alongside standard chemotherapeutic protocols. Sulforaphane is a particularly promising chemopreventive agent, which has been shown to exert proapoptotic effects on tumor cells containing p53 mutations. The p53(Ser220) mutation has been implicated in reduced efficacy and drug resistance in the context of osteosarcomas and breast tumors treated with doxorubicin-based protocols. We investigated the effects of a combination of doxorubicin and sulforaphane on cell viability and apoptosis induction in fibroblasts characterized by different p53 status (p53 wild-type, p53 knock-out, and p53(Ser220) mutation), and identified some of the molecular pathways triggered by the drug combination. Very high concentrations of doxorubicin were necessary to decrease the viability of p53(Ser220) and p53 knock-out (but not wild-type) cells. Treatment of p53(Ser220) and p53 knock-out cells with doxorubicin did not induce apoptosis, also at very high concentrations (10muM). Sulforaphane restored chemosensitivity and induced apoptosis in doxorubicin-resistant p53(Ser220) and p53 knock-out cells, irrespective of p53 status. The induction of apoptosis was caspase-3 dependent and caspase-8 independent. Bongkrekic acid, a mitochondrial membrane stabilizer, partially prevented the effects of doxorubicin plus sulforaphane on mitochondrial permeability but was unable to prevent the induction of apoptosis. N-acetyl-cysteine, a glutathione precursor, blocked the induction of apoptosis by doxorubicin plus sulforaphane. Considering the negligible safety profile of sulforaphane, our findings could prompt innovative clinical studies designed to investigate whether its coadministration can enhance the efficacy of doxorubicin-based regimens

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
