Ibuprofen is more effective than paracetamol for treating pain associated with osteoarthritis OA ; , according to the results of the Ibuprofen, Paracetamol Study in Osteoarthritis 1 IPSO ; . Although paracetamol and ibuprofen are extensively used, very few studies have compared their efficacy in OA pain management. This French study aimed to compare the analgesic efficacy of both drugs in patients with OA. 222 patients aged 50 to 85 years ; with chronic pain defined as a score of at least 50mm on a visual analogue scale [VAS] ; due to confirmed OA of the knee or hip were randomised to ibuprofen 400mg three times daily ; or paracetamol 1g three times daily ; . The primary outcome was patients' assessment of pain intensity.

Current anti-HIV drug regimens, termed highly active antiretroviral therapy HAART ; , typically consist of a combination of at least three antiretroviral drugs, with two or more nucleotide reverse transcriptase inhibitors NRTIs ; being a staple of most regimens [3, 4]. In addition to NRTIs, which are both competitive inhibitors and chain-terminators, the nonnucleoside reverse transcriptase inhibitors NNRTIs ; consist of structurally dissimilar hydrophobic compounds that bind to a hydrophobic pocket on the RT adjacent to, but distinct from, the active site, which accommodates dNTPs and NRTIs. While HAART regimens have decreased both the mortality and morbidity of HIV-infected individuals, several factors contribute to drug failure. The highly error-prone nature of HIV-1 RT [5, 6] combined with a robust rate of viral replication [7, 8] provides the virus with an ideal context for the emergence of resistant variants. In addition, the significant toxicity associated with the current crop of anti-HIV drugs often leads to noncompliance, which in turn results in treatment failure [9]. For these reasons, there is a high level of interest in the development of more potent anti-HIV inhibitors that are both less likely to lead to drug-resistant variants and display less toxicity in patients. Among a number of anti-HIV agents being developed for potential use in the treatment of AIDS are nucleic acidbased inhibitors that can serve as useful complementary therapies [10]. Of these, three nucleic acid-based approaches have recently been shown to have potent influence on HIV replication. In one, using a long antisense env RNA approach, strong inhibition of HIV replication was observed in cultured T cells [11]. This approach combined with a lentiviral vector completed the phase I clinical trials and is about to enter phase II trials [12]. The second approach, RNA interference RNAi ; , uses a natural cellular pathway for gene silencing via small interfering RNAs [13-16]. The third approach is based on DNA and RNA aptamers that are derived by the iterative process of SELEX, to bind to specific protein targets [17] and has been recently shown to be effective in blocking HIV replication [18-20]. Tuerk and Gold first reported the isolation of RNA aptamers targeting HIV-1 RT using an iterative selection process of binding, washing and eluting the RNAs from a random library of RNA sequences [21]. Subsequent reports showed that both DNA and RNA aptamers generated against HIV-1 RT [22, 23] are highly specific do not bind to FIV or MuLV RTs ; , bind tightly to HIV-1 RT Kd in the range of 0.05 to 50 nM ; and competitively inhibit its polymerase activity.
