Trauma, immobilization, and subsequent surgery of the hip and lower limb are associated with a high risk of developing venous thromboembolism (VTE). Individuals undergoing hip fracture surgery (HFS) have the highest rates of VTE among orthopedic surgery and trauma patients. The risk of VTE depends on the type and location of the lower limb injury. Current international guidelines recommend routine pharmacological thromboprophylaxis based on treatment with heparins, fondaparinux, dose-adjusted vitamin K antagonists and acetylsalicylic acid for patients undergoing emergency HFS; however, not all guidelines recommend pharmacological prophylaxis for patients with lower limb injuries...

A novel process for extracting transition metals, recovering lithium and regenerating cathode materials based on facile co-extraction and co-precipitation processes has been developed. 100% manganese, 99% cobalt and 85% nickel are co-extracted and separated from lithium by D2EHPA in kerosene. Then, Li is recovered from the raffinate as Li2CO3 with the purity of 99.2% by precipitation method. Finally, organic load phase is stripped with 0.5M H2SO4, and the cathode material LiNi1/3Co1/3Mn1/3O2 is directly regenerated from stripping liquor without separating metal individually by co-precipitation method...

Foliar application of insecticides has been the most commonly followed practice to manage Phyllocnistis citrella Stainton in nurseries and flush leaves in citrus groves. Leaf dip bioassays were conducted against insecticides, viz., acephate 75SP, dimethoate 30EC, abamectin 1.9EC, fenvalerate 20EC, imidacloprid 17.8SL, and thiamethoxam 25WG, and were tested against P. citrella larvae for their susceptibility. Among six insecticides tested on second-instar P. citrella larvae collected from Nagpur mandarin/acid lime cultivars during 2013-2016, abamectin was the most toxic insecticide for the initial year (LC50 values ranged from 20...

Insecticide resistance in German cockroaches (Blattella germanica (L.)) has been a barrier to effective control since its first documentation in the 1950s. A necessary first step toward managing resistance is to understand insecticide susceptibility profiles in field-collected strains so that active ingredients (AIs) with lowest resistance levels can be identified. As a first step in this study, diagnostic concentrations (DCs) were determined for 14 insecticide AIs based on lethal concentrations that killed 99% or 90% of the individuals from a susceptible lab strain (JWax-S)...

Current multiplexed diagnostics for Zika, dengue, and chikungunya viruses are situated outside the intersection of affordability, high performance, and suitability for use at the point-of-care in resource-limited settings. Consequently, insufficient diagnostic capabilities are a key limitation facing current Zika outbreak management strategies. Here we demonstrate highly sensitive and specific detection of Zika, chikungunya, and dengue viruses by coupling reverse-transcription loop-mediated isothermal amplification (RT-LAMP) with our recently developed quenching of unincorporated amplification signal reporters (QUASR) technique...

BACKGROUND: Proton pump inhibitors (PPIs) are a class of medications that reduce acid secretion and are used for treating many conditions such as gastroesophageal reflux disease (GERD), dyspepsia, reflux esophagitis, peptic ulcer disease, and hypersecretory conditions (e.g. Zollinger-Ellison syndrome), and as part of the eradication therapy for Helicobacter pylori bacteria. However, approximately 25% to 70% of people are prescribed a PPI inappropriately. Chronic PPI use without reassessment contributes to polypharmacy and puts people at risk of experiencing drug interactions and adverse events (e...

Grass carp reovirus (GCRV) is one of the most pathogenic aquareovirus and can cause lethal hemorrhagic disease in grass carp (Ctenopharyngodon idella). However, management of GCRV infection remains a challenge. Therefore, it is necessary to find effective means for the control of its infection. The uses of bacterial ghost (BG, non-living bacteria) as carriers for DNA delivery have received considerable attentions in veterinary and human vaccines studies. Nevertheless, there is still no report about intramuscular administration of bacterial ghost-based DNA vaccines in fish...

Hyaluronic acid (HA) is one of the natural components of the human body with high biocompatibility, biodegradability, and nonimmunogenicity, which makes it the ideal biomedical filling agent currently available. However, for many medical practitioners, HA filler injections remain a relatively new item to carry out. Learning while practicing, it is inevitable to encounter some difficulties and adverse reactions in its application. Here we report two cases of adverse reactions to HA-based filler injections, including anaphylactic reaction on the face and vascular thrombosis after augmentation rhinoplasty with HA filler...

Environmental conditions affect bacterial behavior and can greatly influence the course of an infection. However, the environmental cues that elicit bacterial responses in specific infection sites are relatively unknown. Pseudomonas aeruginosa is ubiquitous in nature and typically innocuous. However, it is also one of the most prevalent causes of fatal sepsis in burn wound patients. The aim of this study was to determine the impact of environmental factors, specifically the availability of arginine, on the pathogenesis of P...

Primary bone marrow edema syndrome (BMES) is characterized by the combination of joint pain and distinctive magnetic resonance imaging changes. It has been suggested that the use of bisphosphonate drugs reduce symptom severity. Our objective was to review cases of patients diagnosed with BMES in the last 7 years who had been treated with zoledronic acid. Access to a pharmaceutical database was gained in order to obtain a list of zoledronic acid prescriptions. Based on clinical and MRI criteria for BMES, patients were selected...

BACKGROUND: Hepatitis C virus (HCV) is a single-stranded RNA (ribonucleic acid) virus that has the potential to cause inflammation of the liver. The traditional definition of acute HCV infection is the first six months following infection with the virus. Another commonly used definition of acute HCV infection is the absence of HCV antibody and subsequent seroconversion (presence of HCV antibody in a person who was previously negative for HCV antibody). Approximately 40% to 95% of people with acute HCV infection develop chronic HCV infection, that is, have persistent HCV RNA in their blood...
