HIV-1 produces defective mutants in the process of reproduction. The significance of the mutants has not been well investigated.

The plasmids of wild type (HIV-1

) and Env-defective (HIV-1



) HIV-1 were co-transfected into HEK293T cells. The progeny virus was collected to infect MT4 cells. The env gene and near-full-length genome (NFLG) of HIV-1 were amplified and sequenced. The phylogenetic diversity, recombinant patterns and hotspots, and the functionality of HIV-1 Env were determined.

A total of 42 env genes and 8 NFLGs were successfully amplified and sequenced. Five types of recombinant patterns of env were identified and the same recombinant sites were detected in different patterns. The recombination hotspots were found distributing mainly in conservative regions of env. The recombination between genes of HIV-1

and HIV-1



increased the variety of viral quasispecies and resulted in progeny viruses with relative lower infectious ability than that of HIV

. The defective env genes as well as NFLG could be detected after 20 passages.

The existence of the defective HIV-1 promotes the phylogenetic evolution of the virus, thus increasing the diversity of virus population. The role of defective genes may be converted from junk genes to useful materials and cannot be neglected in the study of HIV-1 reservoir.

N-terminal pro brain natriuretic peptide (NT-proBNP) and troponin T are released during myocardial wall stress and/or ischemia and are strong predictors for postoperative cardiovascular complications. However, the relative effects of goal-directed, intravenous administration of crystalloid compared to colloid solutions on NT-proBNP and troponin T, especially in relatively healthy patients undergoing moderate- to high-risk noncardiac surgery, remains unclear. Thus, we evaluated in this sub-study the effect of a goal-directed crystalloid versus a goal-directed colloid fluid regimen on postoperative maximum NT-proBNP concentration. We further evaluated the incidence of myocardial injury after noncardiac surgery (MINS) between both study groups.

Thirty patients were randomly assigned to receive additional intravenous fluid boluses of 6% hydroxyethyl starch 130/0.4 and 30 patients to receive lactated Ringer's solution. selleck products Intraoperative fluid management was guided by oesophageal Doppler-according to a previously stered on 6th September 2010.

In the practice of postoperative pain management, pain is still poorly managed in low resource setting where the practice of epidural and opioid free analgesia is impractical. There has been a recent trend of combining different drugs and concept of preemptive analgesia but the therapeutic superiority remains understudied for postoperative pain management. The aim of this study is to assess postoperative analgesic effect of preemptive Paracetamol, Paracetamol-diclofenac and Paracetamol-tramadol combination in patients undergoing laparotomy surgery.

Three-arm, randomized control trial study conducted on 63 patients undergone laparotomy surgery; group-P (paracetamol 1 g), group-PD (1 g + diclofenac 75 mg) and group-PT (paracetamol 1 g + tramadol 100 mg). The Numerical Rating Scale (NRS) pain rating system was used for this study. The primary endpoint of the study was total amount of analgesia consumption. Post-operative analgesic therapy [intravenous tramadol, 50 mg] were provided when patients complain of amadol group compared to paracetamol group.

Preemptive combination of paracetamol-tramadol and paracetamol-diclofenac reduce total tramadol consumption and prolongs time to first analgesic request compared to paracetamol alone in patients undergoing laparotomy surgery.

Antisense oligonucleotides (ASOs) based technology is considered a potential strategy against antibiotic-resistant bacteria; however, a major obstacle to the application of ASOs is how to deliver them into bacteria effectively. DNA tetrahedra (Td) is an emerging carrier for delivering ASOs into eukaryotes, but there is limited information about Td used for bacteria. In this research, we investigated the uptake features of Td and the impact of linkage modes between ASOs and Td on gene-inhibition efficiency in bacteria.

Td was more likely to adhere to bacterial membranes, with moderate ability to penetrate into the bacteria. Strikingly, Td could penetrate into bacteria more effectively with the help of Lipofectamine 2000 (LP2000) at a 0.125 μL/μg ratio to Td, but the same concentration of LP2000 had no apparent effect on linear DNA. Furthermore, linkage modes between ASOs and Td influenced gene-knockdown efficiency. Looped structure of ASOs linked to one side of the Td exhibited better gene-knockdown efficiency than the overhung structure.

This study established an effective antisense delivery system based on loop-armed Td, which opens opportunities for developing antisense antibiotics.
