#1
REVIEW
Xiaofeng Dai, Hongye Cheng, Zhonghu Bai, Jia Li
Breast cancer cell lines have been widely used for breast cancer modelling which encompasses a panel of diseases with distinct phenotypical associations. Though cell lines provide unlimited homogenous materials for tumor studies and are relatively easy to culture, they are known to accumulate mutations duringthe initial establishment and subsequent series of cultivations. Thus, whether breast cancer cell line heterogeneity reflects that of carcinoma remains an important issue to resolve before drawing any reliable conclusion at the tumor level using cell lines...

Life tables provide a means of measuring the schedules of birth and death from populations over time. They also can be used to quantify the sources and rates of mortality in populations, which has a variety of applications in ecology, including agricultural ecosystems. Horizontal, or cohort-based, life tables provide for the most direct and accurate method of quantifying vital population rates because they follow a group of individuals in a population from birth to death. Here, protocols are presented for conducting and analyzing cohort-based life tables in the field that takes advantage of the sessile nature of the immature life stages of a global insect pest, Bemisia tabaci...

Drawing from the tripartite sociocultural model of body image, the researchers examined whether direct messages and modeling from peers, parents, and media were concurrently and prospectively associated with appearance-based rejection sensitivity (appearance-RS) in young adolescents (Mage  = 12.0 years). Appearance-RS was higher among those who concurrently reported more appearance-related teasing and pressure by peers, more parent teasing, and greater acceptance of media appearance ideals. In prospective analyses, greater increases in appearance-RS over 1 year were found for adolescents who perceived higher levels of parental appearance-related teasing and negative attitudes about their own appearance...

Clinical research usually involves time-to-event survival analysis, in which the presence of a competing event is prevalent. It is acceptable to use the conventional Cox proportional hazard regression to model cause-specific hazard. However, this cause-specific hazard cannot directly translate to the cumulative incidence function, and the latter is usually clinically relevant. The subdistribution hazard regression directly quantifies the impact of covariates on the cumulative incidence. When estimating the subdistribution hazard, subjects experiencing competing event continue to contribute to the risk set, and censoring weights are assigned to them after the competing event time...

Rationale: Glioma has a poor survival rate in patients even with aggressive treatment. Temozolomide (TMZ) is the standard chemotherapeutic choice for treating glioma, but TMZ treatment consistently leads to high resistance. Aim: To investigate the underlying mechanisms of TMZ action with new therapeutic regimens in glioma. Methods and results: The biological effects of TMZ mainly depend on the three following DNA repair systems: methylguanine methyltransferase (MGMT), mismatch repair (MMR) and base excision repair (BER)...

There is a growing appreciation that child functioning in different domains, levels, or systems are interrelated over time. Here, we investigate links between internalizing symptoms, externalizing problems, and academic attainment during middle childhood and early adolescence, drawing on two large data sets (child: mean age 8.7 at enrolment, n = 5,878; adolescent: mean age 11.7, n = 6,388). Using a 2-year cross-lag design, we test three hypotheses - adjustment erosion, academic incompetence, and shared risk - while also examining the moderating influence of gender...

Zoonotic transmissions are a major global health risk, and human-animal contact is frequently raised as an important driver of transmission. A literature examining zooanthroponosis largely agrees that more human-animal contact leads to more risk. Yet the basis of this proposition, the term contact, has not been rigorously analyzed. To understand how contact is used to explain cross-species spillovers, we conducted a multi-disciplinary review of studies addressing human-nonhuman primate (NHP) engagements and pathogenic transmissions and employing the term contact...

The surface of a biomaterial can play a major role in its biological fate since the surface is the primary pathway for its interaction with the body. As the natural response of the body to a foreign material is to encapsulate it with a fibrous material, the interactions between the body and the biomaterial are mediated by this fibrous layer. Initial interactions occur between the biomaterial surface, water, ionic species and organic molecules, which then mediate further interactions with body tissues. Surface engineering can influence these interactions and hence, improve the biocompatibility of the biomaterial...

The translationally controlled tumor protein (TCTP) is a highly conserved protein that is regulated due to a high number of extracellular stimuli. TCTP has an important role for cell cycle and normal development. On the other side, tumor reversion and malignant transformation have been associated with TCTP. TCTP has been found among the 12 genes that are differentially expressed during mouse oocyte maturation, and an overexpression of this gene was reported in a wide variety of different cancer types. Its antiapoptotic effect is indicated by the interaction with several proapoptotic proteins of the Bcl-2 family and the p53 tumor suppressor protein...

BACKGROUND: Often, research takes place on underserved populations rather than with underserved populations. This approach can further isolate and stigmatize groups that are already made marginalized. What Goes Around is a community-based research project that was led by community members themselves (Peers). CASE PRESENTATION: This research aimed to implement a community-based research methodology grounded in the leadership and growing research capacity of community researchers and to investigate a topic which community members identified as important and meaningful...

Stone cleavers are one of the most distinctive components of the Acheulian toolkit. These tools were produced as part of a long and complex reduction sequence and they provide indications for planning and remarkable knapping skill. These aspects hold implications regarding the cognitive complexity and abilities of their makers and users. In this study we have analyzed a cleaver assemblage originating from the Acheulian site of Gesher Benot Ya'aqov, Israel, to provide a reconstruction of the chaîne opératoire which structured their production...

The phenomenon of symmetry breaking-in which the order of symmetry of a system is reduced despite manifest higher-order symmetry in the underlying fundamental laws-is pervasive throughout science and nature, playing a critical role in fields ranging from particle physics and quantum theory to cosmology and general relativity. For the growth of crystals, symmetry breaking is the crucial step required to generate a macroscopic shape that has fewer symmetry elements than the unit cell and/or seed crystal from which it grew...

REVIEW
Dimos D Mitsikostas, Douglas S Goodin
Establishing the relative efficacy and safety of the different disease modifying therapies (DMTs) in multiple sclerosis (MS) is critical to the choice of agent that clinicians recommend for individual MS patients. The best evidence for the relative efficacy of the different DMTs comes from head-to-head randomized clinical trials (RCTs). Understanding that outcome-measures with the best established validity are the relapse rate and the actual (not the "confirmed") change in the extended disability status scale (EDSS), we conclude from these head-to-head RCTs that interferon-beta (IFNβ) given subcutaneously multiple times per week (either IFNβ-1b or IFNβ-1a) and glatiramer acetate (GA) are about equivalent in terms of efficacy and that both of these agents, as well as many of the other DMTs, are superior to weekly intramuscular IFNβ-1a...

Superhydrophobic carbon nanotube (CNT) films have demonstrated many fascinating performances in versatile applications, especially for those involving solid/liquid interfacial processes, because of their ability to affect the material/energy transfer at interfaces. Thus, developing superhydrophobic CNTs has attracted extensive research interests in the past decades, and it could be achieved either by surface coating of low-free energy materials or by constructing micro/nanohierarchical structures via various complicated processes...

The association between health literacy (HL) and health outcomes, including self-perceived health (SPH) has been well documented. Yet the complexity of this association is not yet completely clear. Drawing on the Health Literacy Scale (HLS) study in Israel, we examined the association between HL, Internal Health Locus of Control (IHLOC) and SPH among Jews and Arabs. A face-to-face survey was conducted among 242 Arabs and 358 Jews. The questionnaire measured SPH, IHLOC and two measures of HL: a European HLScale (HLS-EU-16) and the Hebrew/Arabic Health Literacy Test (H/AHLT), based on the Short Test Of Functional Health Literacy in Adults...

INTRODUCTION: Fungal interdigital tinea pedis (ITP) is a common pathology mainly due to dermatophytes and yeasts. Fusarium sp. is rarely incriminated in the genesis of intertrigo. In Dakar, a recent study conducted in 2016 on fungal ITP showed that Fusarium were more involved in the etiology of ITP than dermatophytes, coming just after yeasts dominated by Candida. Following this, we wanted to draw attention to the increasing incidence of ITP resulting from Fusarium spp., in Dakar, Senegal, and to analyze the epidemiological and mycological particularities of these ITP due to Fusarium spp...

OBJECTIVES: Although there is increased awareness of patient and public involvement (PPI) among health technology assessment (HTA) organizations, evaluations of PPI initiatives are relatively scarce. Our objective as members of Health Technology Assessment International's (HTAi's) Patient and Citizen Involvement Group (PCIG) was to advance understanding of the range of evaluation strategies adopted by HTA organizations and their potential usefulness. METHODS: In March 2016, a survey was sent to fifty-four HTA organizations through the International Network of Agencies for Health Technology Assessment (INAHTA) and contacts of members of HTAi's PCIG...
