Malaria control with transgenic mosquitoes will be challenging; however, recent advances suggest that it may be a possibility in the foreseeable future. Progress towards discovering refractory genes for rodent malaria and gene drive systems for Drosophila provide hope that similar advances may be made for human malaria in mosquito vector species. That said, the African malaria burden has proved exceptionally difficult to diminish by all means tried thus far; and it is unlikely that transgenic

... squitoes will provide an all-in-one solution. Transgenic mosquitoes should be considered within the context of an integrated vector management strategy which should also include insecticide-treated bed-nets, indoor residual spraying with insecticides and treatment of infected individuals with antimalarial drugs. Integrated strategies will be a necessity for any successful african malaria control program and transgenic mosquitoes should be considered as a potential ingredient in the future goal of continent-wide disease control.

Objectives: Developed countries have been alarmed at the rates of primary/transmitted drug resistance of HIV-1. There is a debate on the validity of certain polymorphisms in HIV-1 Subtype C mutations related to consensus Subtype B sequences being associated with and sometimes mistaken as, primary resistance. In this preliminary study, we have determined polymorphisms in reverse transcriptase (RT) and protease (PR) genes of HIV-1 Subtype C from a patient cohort in Mumbai, India. Methods: The

... y was performed with plasma samples from twenty-four patients (antiretroviral therapy experienced as well as drug-naive) employing a 'home-brew' semi-nested reverse-transcriptase-PCR followed by sequencing and sequence analysis. The Stanford HIV drug-resistance database was used for analysis and interpretation of polymorphisms and other drug-resistance mutations. We also analysed Surveillance Drug Resistance Mutations (SDRMs) for PR gene. Results: Polymorphisms were determined at a mutational frequency of 0.1337 ± 0.042 in PR gene and 0.067 ± 0.014 in RT gene, while 16.6% and 12.5% samples harboured drug-resistance mutations in PR and RT genes respectively. Substitutions greater than 50% were at positions at L19, V82, M36, R41, L63, H69, L89 and I93 for PR gene and D121, K122, T165, K166, K173, D177, T200, Q207 and R211 for RT gene. Additionally, PR gene SDRMs were observed in 15.0% samples. Conclusions: Our findings concur with previous findings that polymorphisms in HIV-1 Subtype C from India exist and re-iterate that these polymorphisms may also include a number of major and minor/accessory mutations associated with resistance. Most of the drug-resistance databases available online are based on Subtype B; hence, we recommend that HIV Subtype-specific drug-resistance databases be created to empower routine and unambiguous surveillance of drug-resistance prior to initiating antiretroviral therapy, especially while including Protease Inhibitors.

IEEE 802.11 is the most popular standard for WLAN networks. It offers different physical transmission rates. This paper focuses on this multi transmission rate of 802.11 WLANs and its effect on speech quality. In non-adaptive systems, when the physical layer switches from a higher transmission rate to a lower one, different than the one that the VoIP flow needs, the switching may result in congestion, high delay and packet loss, and consequently speech quality degradation. However, there are

In this study we demonstrate how choosing parameter (different codec and packet size) can affect the voice quality, network delay and packet loss. Further, this study presents a comparison between adaptive and non-adaptive methods. The adaptive method has also been evaluated for different congestion level from perceived speech quality point of view.

Atherosclerosis related cardiovascular diseases continue to be the primary cause of mortality in developed countries. The elevated level of low density lipoprotein (LDL) is generally considered to be the driver of atherosclerosis, but recent years have seen a shift in this perception in that the vascular plaque buildup is mainly caused by oxidized LDL (ox-LDL) rather than native-LDL. The scavenger receptor LOX-1 found in endothelial cells binds and internalizes ox-LDL which leads to the

... on of plaque formation in arteries. Using virtual screening techniques, we identified a few potential small molecule inhibitors of LOX-1 and tested their inhibitory potential using differential scanning fluorimetry and various cellular assays. Two of these molecules significantly reduced the uptake of ox-LDL by human endothelial cells, LOX-1 transcription and the activation of ERK1/2 and p38 MAPKs in human endothelial cells. In addition, these molecules suppressed ox-LDL-induced VCAM-1 expression and monocyte adhesion onto human endothelial cells demonstrating their therapeutic potential. Atherosclerosis is a chronic progressive disease, and its clinical manifestations include coronary artery disease, cerebrovascular disease and peripheral arterial disease. The interaction between the lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) and oxidatively modified low-density lipoprotein (ox-LDL) plays a significant role in the pathobiology of atherosclerosis, as well as myocardial ischemia and hypertension 1 . Conditions leading to atherosclerosis, such as diabetes, hypertension and dyslipidemia, are associated with a global increase in inflammatory signaling and generation of reactive oxygen species (ROS), leading to enhancement of LDL oxidation. LOX-1 mediates the recognition and internalization of ox-LDL by vascular endothelial cells 2 . Of all known scavenger receptors, LOX-1 is the predominant scavenger receptor in vascular endothelial cell 3, 4 . Recent studies show that blockade of LOX-1 by anti-sense oligo or antibody may reduce myocardial ischemic injury, genesis of hypertension and extent of atherosclerosis 5-8 . Hence, LOX-1 is an attractive target for the therapy of a number of cardiovascular disease states 9 . LOX-1 is a transmembrane protein comprising four domains and the C-terminal domain is responsible for ox-LDL recognition 10,11 . The crystal structure analysis of the C-terminal domain of human LOX-1 (Fig. 1A,B) suggests that it exists as a homodimer with a central hydrophobic tunnel that extends through the entire molecule 12, 13 . Under oxidative stress, LDL undergoes changes making its surface electronegative. The most significant modification pertinent to LOX-1 interaction is the covalent attachment of a phospholipid moiety on the Lys side chains of apolipoprotein B-100, a component of LDL [13] [14] [15] . Modeling studies have shown that the phospholipid moiety fits well into the hydrophobic tunnel of LOX-1 16 . Binding measurements suggest that it ox-LDL binds to LOX-1 with high affinity. Additionally, mutations of certain residues present in

This trial evaluated thoracic endovascular aortic repair (TEVAR) compared with open surgical repair of descending thoracic aortic aneurysms and large ulcers at 42 international sites. Whereas several studies demonstrate early safety and utility advantages with TEVAR, longer follow-up is important because of concerns about durability of TEVAR. Methods: This prospective, nonrandomized study enrolled 160 TEVAR patients treated with the Cook Zenith TX2 and 70 open surgical repair patients. Results:

... Although follow-up was limited, 5-year mortality rate was similar at 37% for both groups. Aneurysm-related mortality rate was 5.9% with TEVAR compared with 12% with open surgical repair (P [ .11). There were no ruptures of the treated aneurysms in either group or open conversions in the TEVAR group. Predefined severe morbidity occurred at a significantly lower rate in TEVAR (21%) compared with open surgical repair (39%; P < .001). Aneurysm growth was seen by core laboratory in 5.9% of patients and endoleak in 5.7% of patients. Secondary intervention rates were similar between TEVAR (8%) and open surgical repair (12%; P [ .49) patients. Conclusions: Five-year results indicate similar all-cause mortality and aneurysm-related mortality with TEVAR compared with open repair. There was a persistent reduction of severe complications with TEVAR. Reinterventions occurred with similar frequency. TEVAR with the TX2 is a safe and effective alternative to open surgical repair for the treatment of anatomically suitable descending thoracic aortic aneurysms and ulcers. (J Vasc Surg 2014;60:1-10.)
