Owing to statin's immune modulatory, anti-inflammatory, antioxidant, antithrombotic and endothelial function actions, they are widely used in the critical care settings in diverse disease scenarios. We aim to explore the evidence to globalize the utilization of statins in the intensive care practice for different indications. We carried out a search of the PubMed, Cochrane and EMBASE databases up to January 2016. We included review articles, meta-analyses, and original trials on the effects of statin therapy in the intensive care unit (ICU) combining the following MESH terms: 'satins', 'intensive care, 'cardiac surgery', 'sepsis', 'acute respiratory distress syndrome' 'pneumonia', subarachnoid hemorrhage', traumatic brain injury and 'critical illness'...

Although there is widespread agreement about the practices associated with multitiered systems of support (MTSS) frameworks in beginning reading, we often underestimate the systems and infrastructure that schools need to implement and sustain these practices. The real work of developing these systems often happens in the detailed-oriented and often messy world of schedules, routines, meetings, and materials. The purpose of this article is to describe a K-3 reading initiative where school teams serving high percentages of students at risk for reading difficulties "delved into the details" to work to overcome the complexities inherent in implementing multitiered reading supports in high priority schools...

Each of the five articles in this special issue gets "into the weeds" in terms of studying actual classroom or school implementation of evidence-based or promising practices. Virtually all confront the issue of logistics and establishing an infrastructure for ensuring adequate implementation. In general, those studies that ask teachers to change their practice, be it core classwide instruction (Wanzek & Vaughn, this issue) or the whole-class adolescent literacy interventions described in LaRusso et al. (this issue) experienced a good deal more in the way of implementation challenges than those that provided schools with extra services and were able to hire their own personnel to train and oversee as part of an efficacy trial...

The purpose of this article is to focus specifically on professional development that is needed to ensure that preservice and in-service teachers are prepared to deliver intensive intervention to enhance reading outcomes of students in special education. Our aim is to provide recommendations to ensure that special educators are prepared to design and implement data-based individualization in the area of reading. We highlight what special educators need to know to implement data-based individualization and provide recommendations for improving professional development using findings from federally funded projects...

Rekha Balu, Fred Doolittle
The articles in this special issue discuss efforts to improve academic reading outcomes for students and ways to achieve high implementation fidelity of promising strategies. At times the authors discuss if-and how-strong fidelity is associated with strong outcomes and potentially even impacts (the difference between program and control group outcomes). We want to explore this theme in two ways: (a) learning from the variation in fidelity to think about potential points of entry and levers for improvement in implementation, and (b) broadening the evaluation focus to include "service contrast" as a factor driving impacts on student outcomes...

The objective of this article is to describe seven elements important to successful implementation of early literacy intervention. The seven elements are drawn from research as well as from the authors' recent randomized controlled trial of effective early literacy interventions in kindergarten through second grade in 55 schools across Florida. The seven elements are (a) the importance of researcher-practitioner partnerships; (b) determining the need for early intervention; (c) assessment selection and data use; (d) evaluating curriculum and instructional materials for use in early intervention; (e) scheduling time for intervention; (f) selecting, training, and supporting interventionists; and (g) locating space and maintaining open communications among interventionists, teachers, and parents...

This commentary discusses how the articles that comprise this special issue conceptualize what is required for reading interventions to change instruction. Three challenges to successful implementation are addressed: identifying institutional barriers to change, identifying intervention components that are not commonly part of the teachers' repertoires and that will require attention and support, and building researcher-practitioner partnerships and a shared understanding of why an intervention would improve reading instruction...

Inhibition of viral replication is the most important goal in patients with Hepatitis B virus chronic infection (CHB). Currently, five oral nucleo(t)side analogues (NAs), including Lamivudine, Adefovir, Telbivudine, Entecavir and Tenofovir, have been approved for treatment. The widespread use of NAs has also been linked with a progressive growth of unlikely anomaly attributable to mitochondrial dysfunctions, not previously recognized. Here we explore the hypothesis that NAs may cause persistent epigenetic changes during prolonged NAs therapy in CHB patients...

Hepatitis E is a major public health problem in developing countries and is increasingly being recognized as a cause of substantial sporadic viral hepatitis infections in industrialized countries. Variable rates of hepatitis E seroprevalence have been reported from the same geographic regions depending on the assay used. In this study, we evaluated the performance characteristics of four assays which included two commercial assays, Wantai HEV-IgG ELISA kit (Wantai, China) and DS-EIA-ANTI-HEV-G kit (DSI, Italy), one NIH-developed immunoassay (NIH-55K, Kuniholm et al...

Xishuangbanna is a popular tourist destination in southern Yunnan Province, bordering with Vietnam and Laos and Myanmar. There are more than 2 million cross-border travelers annually entering China at two land ports, Daluo and Mohan. To clarify the characteristics of HIV-1 prevalence among entry travelers, a retrospective epidemic investigation was conducted. Between 2003 and 2012, 196 among 91,432 entry travelers were detected to be HIV-1-positive, accounting for infection rate of 0.21%. Eighty-one gag-pol gene sequences were obtained for phylogenetic analyses and subsequent recombination analysis...

As a crucial step in ECM remodeling, collagen degradation occurs through different processes, including both extracellular and intracellular degradation. The extracellular pathways of collagen degradation require secretion of collagenolytic proteases, whereas intracellular collagen degradation occurs in the lysosomal compartment after uptake, involving either pre-cleaved or intact fibrillar collagen. The endocytic collagen receptor uPARAP/Endo180 plays an important role in internalization of large collagen degradation products, whereas its role in the phagocytosis of fibrillar collagen has been debated...

Pipecolate, an intermediate of the lysine catabolic pathway, is oxidized to Δ(1) -piperideine-6-carboxylate (P6C) by the flavoenzyme L-pipecolate oxidase (PIPOX). P6C spontaneously hydrolyzes to generate α-aminoadipate semialdehyde, which is then converted into α-aminoadipate acid by α-aminoadipatesemialdehyde dehydrogenase. L-pipecolate was previously reported to protect mammalian cells against oxidative stress. Here, we examined whether PIPOX is involved in the mechanism of pipecolate stress protection...

Full-length genomic sequences of hepatitis E virus (HEV) obtained from two consecutive cases of acute self-limiting hepatitis E in a city in northeast Japan were determined. Interestingly, two HEV isolates from each patient shared nucleotide identity of 99.97% in 7,225 nucleotides, and a phylogenetic analysis showed that they formed a cluster of Japanese isolates that is considered as a new HEV subtype 3k. The high similarity of HEV sequences of two isolates from these patients in this study suggested that a subtype 3k HEV strain had spread via a commonly distributed food in the city, possibly pig liver...

ClC-3 chloride channel has been proved to have a relationship with the expression of osteogenic markers during osteogenesis, persistent static compression can upregulate the expression of ClC-3 and regulate osteodifferentiation in osteoblasts. However, there was no study about the relationship between the expression of ClC-3 and osteodifferentiation after dynamic compression. In this study, we applied dynamic compression on MC3T3-E1 cells to detect the expression of ClC-3, runt-related transcription factor 2 (Runx2), bone morphogenic protein-2 (BMP-2), osteopontin (OPN), nuclear-associated antigen Ki67 (Ki67) and proliferating cell nuclear antigen (PCNA) in biopress system, then we investigated the expression of these genes after dynamic compression with Chlorotoxin (specific ClC-3 chloride channel inhibitor) added...

Cytarabine (AraC) has been the primary treatment agent for Acute Myeloid Leukemia (AML) in the past 30 years, but the precise mechanism of its action is not completely known. Here we assessed the role of ERK5 in AraC-induced cell death in AML cell lines HL60 and U937 using ERK5 inhibitors BIX02189 and XMD8-92. We report that inhibition of MEK5/ERK5 activity reduces AraC-induced cell death, DNA damage, the upregulated DNA damage biomarkers, and produced G2 phase cell cycle arrest. In addition, the pro-survival protein P-Bcl2 Ser70 was found to be associated with decreased AraC-induced cell death following XMD8-92 treatment, suggesting a regulatory role of ERK5 on Bcl2 phosphorylation...

Tomentosin, a natural sesquiterpene lactone purified from of Inula viscosa L., was investigated for its anti-proliferative, telomere shortening and apoptotic effects on human cervical cancer HeLa and SiHa cell lines. Tomentosin was found to inhibit the growth of SiHa and HeLa cell lines in dose and time-dependent manner (IC50 values of 7.10 ± 0.78µM and 5.87 ± 0.36µM, respectively after 96h of treatment). As evidenced by TTAGGG telomere length assay, tomentosin target specifically the telomeric overhang lengthening...

Cancer, in part, is driven, by alterations in cellular metabolism that promote cell survival and cell proliferation. Identifying factors that influence this shift in cellular metabolism in cancer cells is important. Interleukin-1β (IL-1β) is a pro-inflammatory cytokine that has been reported to be elevated in colorectal cancer patients. While much is known towards the effect of dietary nutrients on regulating inflammation and the inflammatory response, which includes cytokines such as IL-1β, far less is understood how cytokines impact nutrient fate to alter cancer cell metabolism...

For the safe long-term storage of high level radioactive waste (HLW), detailed information about geo-chemical behavior of radioactive and toxic metal ions under environmental conditions is important. Natural organic matter (NOM) can play a crucial role in the immobilization or mobilization of these metal ions due to its complexation and colloid formation tendency. In this study, the complexation of europium (as chemical homologue of trivalent actinides like americium) and uranium (as main component of HLW) by ten humic acids (HA) from different sources and Suwannee NOM river extract has been analyzed...

Hepatitis C virus (HCV) is a positive-sense single-stranded RNA virus with an estimated infection in ∼180 million people worldwide, and its chronic infection leads to development of cirrhosis and hepatocellular carcinoma. Although recent development of direct acting antiviral (DAA) compounds improved anti-HCV regimens, alternative therapeutic compounds are still demanded due to an expected emergence of escape mutants for those DAAs. In order to identify novel anti-HCV agents, we conducted chemical library screening for 2,086 compounds using HCV Rep-Feo reporter replicon in Huh7 hepatoma cells...
