In animals, certain viral proteins are targeted to peroxisomes to dampen the antiviral immune response mediated by these organelles(1-3). In plants, RNA interference (RNAi) mediated by small interfering (si)RNA is the main antiviral defence mechanism. To protect themselves against the cell- and non-cell autonomous effects of RNAi, viruses produce viral suppressors of RNA silencing (VSR)(4), whose study is crucial to properly understand the biological cycle of plant viruses and potentially find new solutions to control these pathogens...

OBJECTIVE: To evaluate the effect of global end diastolic volume index (GEDVI) on fluid resuscitation in elderly patients with septic shock. METHODS: A prospective randomized controlled trial (RCT) was conducted. Septic shock patients over 65 years admitted to intensive care unit (ICU) of Shandong Province, Zibo Central Hospital from January 2013 to December 2015 were enrolled. The patients were randomly divided into control group and observation group, 20 cases in each group...

BACKGROUND AND OBJECTIVE: Reports on the efficacy of pneumococcal conjugate vaccines (PCVs) have been received from many countries. However, in countries where the 7-valent PCV (PCV7) and 13-valent PCV (PCV13) were introduced, overall coverage of the serotypes by the vaccine gradually decreased due to pneumococcal serotype replacement. The aim of this study is to assess the distribution of pneumococcal serotypes and to also provide basic data on adult respiratory infection in Japan. METHODS: We analyzed 1086 Streptococcus pneumoniae strains that had been isolated from respiratory tract infection specimens in adult patients from 2006 to 2014...

BACKGROUND: It is controversial as to which ventilation mode is better during one-lung ventilation (OLV). This study was designed to figure out whether there was any difference between volume controlled ventilation (VCV) and pressure controlled ventilation (PCV) on oxygenation and postoperative complications under the condition of protective ventilation (PV). METHODS: Sixty-five patients undergoing video-assisted thoracoscopic lobectomy were randomized into two groups...

The control of malaria relies on the use of chemical antimalarial, but the development of resistance necessitates research into alternatives. Trema orientalis (L.) Blume is used in Nigerian folklore medicine for the treatment of malaria. This study investigates the in vivo antiplasmodial activity of aqueous leaf and bark extracts of T. orientalis in rodent model. Swiss Albino mice weighing 23-27 g were intraperitoneally infected with Plasmodium berghei. The lethal dose in mice was estimated to be greater than 5000 mg/kg based on toxicity signs and death...

Background.: Pneumococcal conjugate vaccines (PCVs) are highly effective in preventing invasive pneumococcal disease (IPD), but deaths due to IPD still occur. We aimed to describe children who died of IPD since PCV introduction in England and Wales. Methods.: Public Health England conducts enhanced IPD surveillance in England and Wales. IPD cases in PCV-eligible children aged <5 years (born since 4 September 2004 and diagnosed between 4 September 2006 and 3 September 2014) were actively followed up by postal questionnaires and, for fatal cases, detailed information was requested prospectively from multiple sources...

BACKGROUND: Declines in Hickory shad (Alosa mediocris) populations in Chesapeake Bay have prompted efforts at captive propagation of wild broodfish for stock enhancement and research. OBJECTIVE: The objectives of this study were to evaluate injuries sustained, and immediate and delayed (24 hours) effects on blood variables related to 2 fish capturing methods (electrofishing [EF] and angling). METHODS: Blood specimens were collected from fish immediately following capture by EF and angling (n = 40 per sex and capture method) from the Susquehanna River (MD, USA)...

BACKGROUND: Vaccination using the 10-valent conjugate vaccine (PCV-10) was introduced into the Extended Program on Immunization in Mozambique in March 2013, however its impact on pediatric pneumococcal meningitis is unknown. In this study, we assessed for the first time the impact of PCV10 on the burden of pneumococcal meningitis in children less than 5 years of age at the three largest hospitals in Mozambique. METHOD: Between March 2013 and December 2015, a total of 744 cerebrospinal fluid (CSF) samples were collected from eligible children, of which 160 (21...

BACKGROUND: Pneumococcal conjugate vaccines (PCVs) are used in many low-income countries but their impact on the incidence of pneumonia is unclear. The Gambia introduced PCV7 in August, 2009, and PCV13 in May, 2011. We aimed to measure the impact of the introduction of these vaccines on pneumonia incidence. METHODS: We did population-based surveillance and case-control studies. The primary endpoint was WHO-defined radiological pneumonia with pulmonary consolidation...

Flaviviruses such as West Nile virus (WNV), dengue virus and Zika virus are mosquito-borne pathogens that cause significant human diseases. A novel group of insect-specific flaviviruses (ISFs), which only replicate in mosquitoes, have also been identified. However, little is known about the mechanisms of ISF host restriction. We report the generation of infectious cDNA from two Australian ISFs, Parramatta River virus (PaRV) and Palm Creek virus (PCV). Using circular polymerase extension cloning (CPEC) with a modified OpIE2 insect promoter, infectious cDNA was generated and transfected directly into mosquito cells to produce infectious virus indistinguishable from wild-type virus...

BACKGROUND: The World Health Organisation recommends the use of catch-up campaigns as part of the introduction of pneumococcal conjugate vaccines (PCVs) to accelerate herd protection and hence PCV impact. The value of a catch-up campaign is a trade-off between the costs of vaccinating additional age groups and the benefit of additional direct and indirect protection. There is a paucity of observational data, particularly from low- and middle-income countries, to quantify the optimal breadth of such catch-up campaigns...

PURPOSE: To examine the recurrence rate of choroidal neovascularization (CNV) lesion activity in age-related macular degeneration (AMD) and associated factors after 1-year aflibercept treatment. METHODS: Age-related macular degeneration eyes with 1-year aflibercept fixed-regimen treatment and a follow-up period of at least 18 months from the initial aflibercept injection for treatment-naive exudative AMD were retrospectively evaluated. The recurrence rate was examined...

BACKGROUND: Baseline hematologic data are used by veterinarians and wildlife biologists to perform health assessments on target animal species. Hematologic measurements are influenced by various factors including geography. Baseline hematologic RIs have been established for domestic water buffaloes (Bubalus bubalis) from various countries in the Eastern Hemisphere, but these data are not readily available for the Western Hemisphere. OBJECTIVE: The aim of this study was to determine hematologic values for domestic water buffaloes from several commercial farms in southern Mexico...

INTRODUCTION: Widespread introduction of pneumococcal conjugated vaccines (PCVs) impacted on invasive pneumococcal disease (IPD). However, IPD reduction may not be similar in all outcomes within IPD. We assessed PCV7/PCV13 impact on pneumococcal meningitis, bacteremic pneumonia (BP) and other (non-meningitis, non-pneumonia) IPD episodes in children <5years in Israel. METHODS: A prospective, population-based, active nationwide surveillance. All pneumococcal invasive episodes with positive blood/CSF cultures, July 2000 through June 2016, were included...

Porcine circovirus type 2 (PCV2) is the cause of postweaning multisystemic wasting syndrome (PMWS), which encompasses several distinct symptoms in pigs. PCV2 infection and clinical incidence of PMWS have increased in recent years, possibly due to shifts in viral populations and mutations. In this study, we identified PVC2 strains currently afflicting pig populations in mainland China, because this is a prerequisite for developing a specific vaccine to control the spread of PMWS. We collected 235 tissue samples from 16 provinces between 2014 and 2016...

Malignant theileriosis (Theileria lestoquardi infection) is a hemoparasitic tick-borne disease that affects both wild and domestic small ruminants. The aim of this study was to evaluate biochemical and hematological characteristics of sheep after being experimentally infected by T. lestoquardi. T. lestoquardi infection was induced in seven Baluchi sheep of six-to-eight months old via experimentally-infected Hyalomma anatolicum adult ticks. Biochemical and hematological parameters were measured twice a week during the three weeks' post infection...
