Approximately two decades ago, thoracic surgery witnessed the leap from thoracotomy to the first video-assisted thoracic surgery (VATS) lobectomy. Minimally invasive lobectomy and hilar lymphadenectomy is now widely established as a safe and oncological sound technique that is the standard of care for early-stage lung cancer. The move toward less invasive surgery has no doubt driven the innovation of sophisticated instruments and technology to cope with the demanding need of working through a restricted incision...

The highly conserved eukaryotic Elongator complex performs specific chemical modifications on wobble base uridines of tRNAs, which are essential for proteome stability and homeostasis. The complex is formed by six individual subunits (Elp1-6) that are all equally important for its tRNA modification activity. However, its overall architecture and the detailed reaction mechanism remain elusive. Here, we report the structures of the fully assembled yeast Elongator and the Elp123 sub-complex solved by an integrative structure determination approach showing that two copies of the Elp1, Elp2, and Elp3 subunits form a two-lobed scaffold, which binds Elp456 asymmetrically...

REVIEW

Epidemiological studies indicate that hyperuricaemia is an independent risk factor for cardiovascular disease. Alongside uric acid formation, increased xanthine oxidase activity also results in the formation of oxidative free radicals and superoxide particles. Oxidative stress significantly contributes to the development of cardiovascular disease, including endothelial cell dysfunction, atherosclerosis, vascular calcification and impaired myocardial energetics. Allopurinol, a competitive xanthine oxidase inhibitor, in addition to reducing serum uric acid levels, can act as a free radical scavenger...

BACKGROUND: The effects of backpack load on young adults' gait parameters have received little attention. We previously reported that with a backpack load within 15% body weight, young adults maintain their gait parameters at the expense of increased exertion during a 6-minute walk at self-selected normal walking speed. However, the effect of backpack strap pattern on gait parameters during faster walking or longer stride length has not been evaluated. OBJECTIVE: To determine the effect of different backpack strap patterns on gait parameters during a 12-minute walk test in young adults at self-selected normal and fast walking speeds...

During translation elongation, decoding is based on the recognition of codons by corresponding tRNA anticodon triplets. Molecular mechanisms that regulate global protein synthesis via specific base modifications in tRNA anticodons are receiving increasing attention. The conserved eukaryotic Elongator complex specifically modifies uridines located in the wobble base position of tRNAs. Mutations in Elongator subunits are associated with certain neurodegenerative diseases and cancer. Here we present the crystal structure of D...

Non-vitamin K antagonist oral anticoagulants (NOACs) reduce the risk of thromboembolism in patients with atrial fibrillation (AF). There has been no head-to-head comparison of the effect of these agents on ex vivo thrombotic and thrombolytic status. Enhanced platelet reactivity and impaired endogenous thrombolysis are risk factors for recurrent thrombotic events. We aimed to assess the comparative effect of NOACs and warfarin using an ex vivo test of thrombosis and thrombolysis. Eighty patients with newly diagnosed non-valvular AF were tested before, and after being established on apixaban (n = 20), dabigatran (n = 20), rivaroxaban (n = 20), or warfarin (n = 20)...

This project was undertaken to find ways of reducing mortalities and economic losses due to velogenic Newcastle disease (VND) in areas where the disease is enzootic. Four groups of cockerels of 44 birds each were used for this experiment. The birds in groups 1 and 2 received no dietary vitamin A supplementation, whereas groups 3 and 4 received 300 iu and 600 iu of vitamin A per kilogram of commercial feed, respectively, from 1 week of age till the end of the experiment. At 6 weeks of age, the birds in groups 2, 3 and 4 were inoculated intraocularly with a VND virus (duck/Nigeria/Plateau/Kuru/113/1991)...

INTRODUCTION: With the first case of Human Immunodeficiency Virus infection/Acquired Immunodeficiency Syndrome (HIV/AIDS) identified in 1986, the management of HIV/AIDS in Nigeria has evolved through the years. The emergency phase of the HIV/AIDS program, aimed at containing the HIV/AIDS epidemic within a short time frame, was carried out by international agencies that built structures separate from hospitals' programs. It is imperative that Nigeria shifts from the previous paradigm to the concept of Commonization of HIV to achieve sustainability...

REVIEW
Osita N Okafor, Diana A Gorog
Most acute cardiovascular events are attributable to arterial thrombosis. Plaque rupture or erosion stimulates platelet activation, aggregation, and thrombosis, whilst simultaneously activating enzymatic processes that mediate endogenous fibrinolysis to physiologically maintain vessel patency. Interplay between these pathways determines clinical outcome. If proaggregatory factors predominate, the thrombus may propagate, leading to vessel occlusion. However, if balanced by a healthy fibrinolytic system, thrombosis may not occur or cause lasting occlusion...
