Sudden synchrony leaps accompanied by frequency multiplications in neuronal activity  

PubMed Central

A classical view of neural coding relies on temporal firing synchrony among functional groups of neurons, however, the underlying mechanism remains an enigma. Here we experimentally demonstrate a mechanism where time-lags among neuronal spiking leap from several tens of milliseconds to nearly zero-lag synchrony. It also allows sudden leaps out of synchrony, hence forming short epochs of synchrony. Our results are based on an experimental procedure where conditioned stimulations were enforced on circuits of neurons embedded within a large-scale network of cortical cells in vitro and are corroborated by simulations of neuronal populations. The underlying biological mechanisms are the unavoidable increase of the neuronal response latency to ongoing stimulations and temporal or spatial summation required to generate evoked spikes. These sudden leaps in and out of synchrony may be accompanied by multiplications of the neuronal firing frequency, hence offering reliable information-bearing indicators which may bridge between the two principal neuronal coding paradigms.

Active Learning in the Physics Classroom  

NASA Astrophysics Data System (ADS)

Many students enter physics classes filled with misconceptions about physics concepts. Students tend to retain these misconceptions into their adult lives, even after physics instruction. Constructivist researchers have found that students gain understanding through their experiences. Researchers have also found that active learning practices increase conceptual understanding of introductory physics students. This project study sought to examine whether incorporating active learning practices in an advanced placement physics classroom increased conceptual understanding as measured by the force concept inventory (FCI). Physics students at the study site were given the FCI as both a pre- and posttest. Test data were analyzed using two different methods---a repeated-measures t test and the Hake gain method. The results of this research project showed that test score gains were statistically significant, as measured by the t test. The Hake gain results indicated a low (22.5%) gain for the class. The resulting project was a curriculum plan for teaching the mechanics portion of Advanced Placement (AP) physics B as well as several active learning classroom practices supported by the research. This project will allow AP physics teachers an opportunity to improve their curricular practices. Locally, the results of this project study showed that research participants gained understanding of physics concepts. Social change may occur as teachers implement active learning strategies, thus creating improved student understanding of physics concepts.

Structural Changes Accompanying Enzymatic Activation of Human Hageman Factor  

PubMed Central

The structure of Hageman factor, isolated from human plasma, was analyzed before and after enzymatic activation. The purified molecule is a single polypeptide chain of 80,000 molecular weight (mol wt) sedimenting at 4.5S. An amino acid analysis has been performed. The concentration of Hageman factor in normal human plasma was found to be 29 ?g/ml with variation between individuals ranging from 15 to 47 ?g/ml. Treatment of the molecule with kallikrein, plasmin, or trypsin resulted in cleavage at two primary sites, yielding fragments of 52,000, 40,000, and 28,000 mol wt. No further changes occurred in the fragments with subsequent reduction. Prekallikrein-activating ability was associated exclusively with the 28,000 moiety. PMID:4277669

The discourse of design-based science classroom activities  

NASA Astrophysics Data System (ADS)

This paper is an initial contribution to a general theory in which science classroom activity types and epistemological discourse practices are systematically linked. The idea is that activities and discourse are reflexively related, so that different types of science classroom activities (e.g., scientific argumentation, modeling, and design) recruit characteristically distinct forms of participants' (students and teacher) discourse. Such a general theory would eventually map out the full spectrum of discourse practices (and their patterns of manifestation) across various kinds of science classroom activities, and reveal new relationships between forms of both discourse and activities. Because this defines a complex and long-term project, here our aim is simply to delineate this larger theoretical program and to illustrate it with a detailed case study—namely, that of mapping out and characterizing the discourse practices of design-based science classroom activities. To do so, we draw on data from an activity that is prototypically design-based—i.e., one in which students iteratively design and refine an artifact (in this case, pictorial representations of moving objects)—and examine the structure and dynamics of the whole-class discourse practices that emerge around these representational forms. We then compare and contrast these discourse practices to those of an activity that is prototypical of scientific argumentation (taken from the literature)—i.e., one in which students argue between competing theories and explanations of a phenomenon—and begin to illustrate the kinds of insights our theoretical program might afford.

Constitutive intestinal NF-?B does not trigger destructive inflammation unless accompanied by MAPK activation.  

PubMed

Nuclear factor (NF)-?B, activated by I?B kinase (IKK), is a key regulator of inflammation, innate immunity, and tissue integrity. NF-?B and one of its main activators and transcriptional targets, tumor necrosis factor (TNF), are up-regulated in many inflammatory diseases that are accompanied by tissue destruction. The etiology of many inflammatory diseases is poorly understood, but often depends on genetic factors and environmental triggers that affect NF-?B and related pathways. It is unknown, however, whether persistent NF-?B activation is sufficient for driving symptomatic chronic inflammation and tissue damage. To address this question, we generated IKK?(EE)(IEC) mice, which express a constitutively active form of IKK? in intestinal epithelial cell (IECs). IKK?(EE)(IEC) mice exhibit NF-?B activation in IECs and express copious amounts of inflammatory chemokines, but only small amounts of TNF. Although IKK?(EE)(IEC) mice exhibit inflammatory cell infiltration in the lamina propria (LP) of their small intestine, they do not manifest tissue damage. Yet, upon challenge with relatively mild immune and microbial stimuli, IKK?(EE)(IEC) mice succumb to destructive acute inflammation accompanied by enterocyte apoptosis, intestinal barrier disruption, and bacterial translocation. Inflammation is driven by massive TNF production, which requires additional activation of p38 and extracellular-signal-regulated kinase mitogen-activated protein kinases (MAPKs). PMID:21825016

Effectiveness of classroom response systems within an active learning environment.  

PubMed

In nursing education, the inclusion of pedagogical tools is necessary to transform Millennial classrooms. One such pedagogical tool currently offered is classroom response systems (CRS). The purpose of this study was to evaluate the effectiveness of CRS as a pedagogical tool in improving nursing students' examination performance within an active learning environment. A pretest-posttest design was used to determine whether there was a relationship between the use of CRS (independent variable) and nursing students' examination performance in a first-year Professional Practice course (dependent variable). Paired t tests revealed no greater improvement in posttest scores. Therefore, the use of CRS technology was not effective in increasing nursing students' examination scores in the Professional Practice course. Additional research is needed to provide adequate understanding of the effectiveness of CRS within the nursing education classroom. PMID:24127175

Earth-Shaking Seismology Activities for Middle School Classrooms  

NASA Astrophysics Data System (ADS)

A sequence of related earthquake and seismology activities provides an effective curriculum unit for inquiry-based science for the middle school level. The activities allow hands-on and in-depth study, progress from relatively simple "low-tech" approaches to more advanced activities emphasizing problem-solving and use of technology, and involve significant practice with science process skills. The unit begins with an earthquake plotting activity in which student teams find recent earthquake information from the Internet and plot epicenters on a classroom map. The activity continues throughout the year and provides opportunities for discovery, connections to other seismology activities, developing map skills, and cooperative learning. Subsequent activities include investigations of plate tectonics, plate boundaries, Earth's interior structure, seismic wave propagation, plotting earthquakes and volcanic eruptions on the computer using Alan Jones' Seismic/Eruption software, earthquake hazards, magnitude and intensity scales, and use of an educational seismograph in the classroom. The near real time monitoring of earthquakes provided by the mapping exercises and the educational seismograph, and the relevance of earthquake studies, generate student excitement and long term impact. We have shared this approach and the activities with K-12 teachers in many professional development settings. Many of the activities are available online at: www.eas.purdue.edu/~braile.

Adventures in Paleontology: 36 Classroom Fossil Activities  

NSDL National Science Digital Library

Millions of years after vanishing from the Earth, dinosaurs still have the power to stir students' curiosity. Deepen that interest with Adventures in Paleontology, a series of lively hands-on activities especially for middle schoolers. This beautifully illustrated full color book features 36 activities that open students up to a variety of foundational sciences, including biology, geology, chemistry, physics, and astronomy. For example: � "How Do Fossils Form?" discusses how organisms become fossils and illustrates the concept with activities that simulate fossil-making processes. � "What Can You Learn From Fossils?" explores what fossils teach about ancient organisms. � "Mass Extinction and Meteor Collisions With Earth" discusses recently discovered links between meteor and asteroid impacts on Earth and the demise of animals like dinosaurs. Other chapters cover how to tell the age of the Earth; how dinosaurs evolved; and diversity, classification, and taxonomy. The final chapters offer humanistic perspectives on fossils in literature and art. As an attention-grabbing complement to the text, vivid full color illustrations show not just skeletons and animal tracks but also what dinosaurs probably looked like in their natural settings. Handy line drawings guide students through each step of the activities.

Cultural ecology of dietary change accompanying changing activity patterns among the Shipibo  

SciTech Connect

Shipibo Indians, who formed a village to establish a school and health clinic, are gradually depleting local fish and game resources. Men, recently adopting rice as a cash crop, tend to fish and hunt less than other men working only their subsistence gardens. Sale of fish and game in the village is becoming common, and pigs, once raised exclusively for sale to non-Shipibo, are now more regularly eaten and used for attracting agricultural labor. Other research has indicated that cash cropping often competes for workers' time in subsistence and so dietary change usually accompanies changing activity patterns. This paper explores the latter possibility by examining the relationship between cash cropping, wild meat procurement, and diet among the Shipibo. Time allocation and food consumption data are analyzed statistically to test a mathematical theory and model which relates indigenous work patterns to diet.

Brown adipose tissue function is accompanied by cerebral activation in lean but not in obese humans.  

PubMed

Brown adipose tissue (BAT) is able to generate heat and dissipate energy in response to cold exposure in mammals. It has recently been acknowledged that adult humans also have functional BAT, whose metabolic activity is reduced in obesity. In healthy humans, the cerebral mechanisms that putatively control BAT function are unclear. By using positron emission tomography (PET), we showed that cold-induced BAT activation is associated with glucose metabolism in the cerebellum, thalamus, and cingulate, temporoparietal, lateral frontal, and occipital cortices in lean participants, whereas no such associations were found under warm control conditions. The cold-induced increase in cerebral glucose metabolism was more robust in lean than obese participants. Cerebral glucose metabolism was not associated with skeletal muscle or white adipose tissue glucose uptake under warm or cold conditions. In conclusion, BAT metabolism was accompanied by the activation of specific cerebral regions, and this shows an uncharacterized role that the brain plays in the regulation of BAT function. In obese participants, the cold-induced response in cerebral activity was attenuated that provides a clue for obesity-induced impairment in BAT metabolism. PMID:24667912

Acoustical conditions for speech communication in active elementary school classrooms  

NASA Astrophysics Data System (ADS)

Detailed acoustical measurements were made in 34 active elementary school classrooms with typical rectangular room shape in schools near Ottawa, Canada. There was an average of 21 students in classrooms. The measurements were made to obtain accurate indications of the acoustical quality of conditions for speech communication during actual teaching activities. Mean speech and noise levels were determined from the distribution of recorded sound levels and the average speech-to-noise ratio was 11 dBA. Measured mid-frequency reverberation times (RT) during the same occupied conditions varied from 0.3 to 0.6 s, and were a little less than for the unoccupied rooms. RT values were not related to noise levels. Octave band speech and noise levels, useful-to-detrimental ratios, and Speech Transmission Index values were also determined. Key results included: (1) The average vocal effort of teachers corresponded to louder than Pearsons Raised voice level; (2) teachers increase their voice level to overcome ambient noise; (3) effective speech levels can be enhanced by up to 5 dB by early reflection energy; and (4) student activity is seen to be the dominant noise source, increasing average noise levels by up to 10 dBA during teaching activities.

Conformational changes accompany activation of reovirus RNA-dependent RNA transcription  

PubMed Central

Many critical biologic processes involve dynamic interactions between proteins and nucleic acids. Such dynamic processes are often difficult to delineate by conventional static methods. For example, while a variety of nucleic acid polymerase structures have been determined at atomic resolution, the details of how some multi-protein transcriptase complexes actively produce mRNA, as well as conformational changes associated with activation of such complexes, remain poorly understood. The mammalian reovirus innermost capsid (core) manifests all enzymatic activities necessary to produce mRNA from each of the 10 encased double-stranded RNA genes. We used rapid freezing and electron cryo-microscopy to trap and visualize transcriptionally active reovirus core particles and compared them to inactive core images. Rod-like density centered within actively transcribing core spike channels was attributed to exiting nascent mRNA. Comparative radial density plots of active and inactive core particles identified several structural changes in both internal and external regions of the icosahedral core capsid. Inactive and transcriptionally active cores were partially digested with trypsin and identities of initial tryptic peptides determined by mass spectrometry. Differentially-digested peptides, which also suggest transcription-associated conformational changes, were placed within the known 3-dimensional structures of major core proteins. PMID:18321727

Caspase-Like Activities Accompany Programmed Cell Death Events in Developing Barley Grains  

PubMed Central

Programmed cell death is essential part of development and cell homeostasis of any multicellular organism. We have analyzed programmed cell death in developing barley caryopsis at histological, biochemical and molecular level. Caspase-1, -3, -4, -6 and -8-like activities increased with aging of pericarp coinciding with abundance of TUNEL positive nuclei and expression of HvVPE4 and HvPhS2 genes in the tissue. TUNEL-positive nuclei were also detected in nucellus and nucellar projection as well as in embryo surrounding region during early caryopsis development. Quantitative RT-PCR analysis of micro-dissected grain tissues revealed the expression of HvVPE2a, HvVPE2b, HvVPE2d, HvPhS2 and HvPhS3 genes exclusively in the nucellus/nucellar projection. The first increase in cascade of caspase-1, -3, -4, -6 and -8-like activities in the endosperm fraction may be related to programmed cell death in the nucellus and nucellar projection. The second increase of all above caspase-like activities including of caspase-9-like was detected in the maturating endosperm and coincided with expression of HvVPE1 and HvPhS1 genes as well as with degeneration of nuclei in starchy endosperm and transfer cells. The distribution of the TUNEL-positive nuclei, tissues-specific expression of genes encoding proteases with potential caspase activities and cascades of caspase-like activities suggest that each seed tissue follows individual pattern of development and disintegration, which however harmonizes with growth of the other tissues in order to achieve proper caryopsis development.

The measurable heat flux that accompanies active transport by Ca2+-ATPase.  

PubMed

We present a new mesoscopic basis which can be used to derive flux equations for the forward and reverse mode of operation of ion-pumps. We obtain a description of the fluxes far from global equilibrium. An asymmetric set of transport coefficients is obtained, by assuming that the chemical reaction as well as the ion transports are activated, and that the enzyme has a temperature independent of the activation coordinates. Close to global equilibrium, the description reduces to the well known one from non-equilibrium thermodynamics with a symmetric set of transport coefficients. We show how the measurable heat flux and the heat production under isothermal conditions, as well as thermogenesis, can be defined. Thermogenesis is defined via the onset of the chemical reaction or ion transports by a temperature drop. A prescription has been given for how to determine transport coefficients on the mesocopic level, using the macroscopic coefficient obtained from measurements, the activation enthalpy, and a proper probability distribution. The method may give new impetus to a long-standing unsolved transport problem in biophysics. PMID:19060976

Amphetamine sensitization is accompanied by an increase in prelimbic cortex activity.  

PubMed

Drug addiction is associated with dysfunction in the medial prefrontal cortex (mPFC). However, the modifications of neuronal activity in mPFC underlying the reinforcing properties of addictive drugs are still unclear. Here we carried out single-unit recording experiments to study the neuronal activity in the prelimbic (PL) cortex of anesthetized rats, after expression of locomotor sensitization to amphetamine. In control rats, an acute injection of amphetamine induced mainly an inhibitory effect on firing rate (FR) and this response was negatively correlated with the basal FR. Sensitized rats showed a higher proportion of excited neurons and the response to amphetamine was independent of basal FR. Moreover, in control rats, acute amphetamine decreased burst rate, whereas in sensitized rats acute amphetamine increased burst rate. These findings indicate that amphetamine sensitization renders mPFC neurons hyperexcitable. Taken together, these data support the hypothesis that early withdrawal is associated with an increase in the activity of the mPFC, which could strengthen the PL-Nucleus Accumbens connection, thus facilitating amphetamine-induced locomotor sensitization.

Perezhivanie and classroom discourse: a cultural-historical perspective on "Discourse of design based science classroom activities"  

NASA Astrophysics Data System (ADS)

Flavio Azevedo, Peggy Martalock and Tugba Keser challenge the `argumentation focus of science lessons' and propose that through a `design-based approach' emergent conversations with the teacher offer possibilities for different types of discussions to enhance pedagogical discourse in science classrooms. This important paper offers a "preliminary contribution to a general theory" regarding the link between activity types and discourse practices. Azevedo, Martalock and Keser offer a general perspective with a sociocultural framing for analysis of classroom discourse. Interestingly the specific concepts drawn upon are from conversation analysis; there are few sociocultural concepts explored in detail. Therefore, in this article we focus on a cultural historical (Vygotsky in The collected works of L. S. Vygotsky. The history and development of higher mental functions, vol 4. Plenum Press, New York, 1987; The Vygotsky reader. Black, Cambridge, 1994) methodology to explore, analyse and explain how we would use a different theoretical lens. We argue that a cultural historical reading of argumentation in science lessons and design based activity will expand Azevedo, Martalock and Keser's proposed general theory of activity types and discourse practices. Specifically, we use Lev Vygotksy's idea of perezhivanie as the unit of analysis to reconceptualise this important paper. We focus on the holistic category of students' emotional experience through discourse while developing scientific awareness.

T-cell activation is accompanied by an ubiquitination process occurring at the immunological synapse.  

PubMed

The immunological synapse (IS) is a specialized signaling area formed at the contact site between T-cells and antigen-presenting cells (APC), where sustained engagement and signaling of TCR and accessory molecules occur. A key feature of T-cell antigen recognition is that the process of TCR/peptide-MHC interaction is self-limited by the internalization and degradation of triggered TCR and recruited signaling components. The mechanism of signaling component degradation involves their ubiquitination and targeting for degradation. Yet, the relationship between the ubiquitination process and TCR signaling as well as the cellular localization of TCR-induced ubiquitination are still elusive. In the present work, we visualize for the first time ubiquitination at the TCR signaling area. We show an enrichment of ubiquitin staining in TCR/CD3 caps in T-lymphocytes stimulated by anti-CD3 antibodies. Remarkably, we also show the recruitment of the ubiquitin ligase Cbl-b and a significant ubiquitination at the immunological synapse in antigen-stimulated T-cells. Our results identify the immunological synapse as the cellular area where TCR-induced protein ubiquitination occurs. They imply that the synapse is a specialized site where the activation process is not only triggered, but also controlled via ubiquitination of signaling actors. PMID:15790509

Age?related remodeling of small arteries is accompanied by increased sphingomyelinase activity and accumulation of long?chain ceramides  

PubMed Central

Abstract The structure and function of large arteries alters with age leading to increased risk of cardiovascular disease. Age?related large artery remodeling and arteriosclerosis is associated with increased collagen deposition, inflammation, and endothelial dysfunction. Bioactive sphingolipids are known to regulate these processes, and are also involved in aging and cellular senescence. However, less is known about age?associated alterations in small artery morphology and function or whether changes in arterial sphingolipids occur in aging. We show that mesenteric small arteries from old sheep have increased lumen diameter and media thickness without a change in media to lumen ratio, indicative of outward hypertrophic remodeling. This remodeling occurred without overt changes in blood pressure or pulse pressure indicating it was a consequence of aging per se. There was no age?associated change in mechanical properties of the arteries despite an increase in total collagen content and deposition of collagen in a thickened intima layer in arteries from old animals. Analysis of the sphingolipid profile showed an increase in long?chain ceramide (C14–C20), but no change in the levels of sphingosine or sphingosine?1?phosphate in arteries from old compared to young animals. This was accompanied by a parallel increase in acid and neutral sphingomyelinase activity in old arteries compared to young. This study demonstrates remodeling of small arteries during aging that is accompanied by accumulation of long?chain ceramides. This suggests that sphingolipids may be important mediators of vascular aging. PMID:24872355

Ectopic Lipid Accumulation and Reduced Glucose Tolerance in Elderly Adults Are Accompanied by Altered Skeletal Muscle Mitochondrial Activity  

PubMed Central

Context: Aging is associated with insulin resistance and unfavorable changes in body composition including increased fat accumulation, particularly in visceral and ectopic depots. Recent studies suggest that skeletal muscle mitochondrial activity may underlie some age-associated metabolic abnormalities. Objective: Our objective was to measure mitochondrial capacity and coupling of the vastus lateralis muscle in elderly and young adults using novel in vivo approaches and relate mitochondrial activity to metabolic characteristics. Design: This was a cross-sectional study. Participants and Intervention: Fourteen sedentary young (seven males and seven females, 20–34 yr of age) and 15 sedentary elderly (seven males and eight females, 70–84 yr of age) nonobese subjects selected for similar body weight underwent measures of body composition by magnetic resonance imaging and dual-energy x-ray absorptiometry, oral glucose tolerance, and in vivo mitochondrial activity by 31P magnetic resonance and optical spectroscopy. Muscle biopsy was carried out in the same muscle to measure mitochondrial content, antioxidant activity, fiber type, and markers of mitochondrial biogenesis. Results: Elderly volunteers had reduced mitochondrial capacity (P = 0.05) and a trend for decreased coupling efficiency (P = 0.08) despite similar mitochondrial content and fiber type distribution. This was accompanied by greater whole-body oxidative stress (P = 0.007), less skeletal muscle mass (P < 0.001), more adipose tissue in all depots (P ? 0.002) except intramyocellular (P = 0.72), and lower glucose tolerance (P = 0.07). Conclusions: Elderly adults show evidence of altered mitochondrial activity along with increased adiposity, oxidative stress, and reduced glucose tolerance, independent of obesity. We propose that mild uncoupling may be induced secondary to age-associated oxidative stress as a mechanism to dissipate the proton-motive force and protect against further reactive oxygen species production and damage.

Chromatin condensation during apoptosis is accompanied by degradation of lamin A+B, without enhanced activation of cdc2 kinase  

PubMed Central

Chromatin condensation paralleled by DNA fragmentation is one of the most important criteria which are used to identify apoptotic cells. However, comparable changes are also observed in interphase nuclei which have been treated with cell extracts from mitotic cells. In this respect it is known that in mitosis, the lamina structure is broken down as a result of lamin solubilization and it is possible that a similar process is happening in apoptotic cells. The experiments described in this study have used confluent cultures of an embryonic fibroblast cell line which can be induced to undergo either apoptosis at low serum conditions or mitosis. Solubilization of lamin A+B was analyzed by immunoblotting and indirect immunofluorescence. These studies showed that in mitotic cells lamina breakdown is accompanied by lamin solubilization. In apoptotic cells, a small amount of lamin is solubilized before the onset of apoptosis, thereafter, chromatin condensation is accompanied by degradation of lamin A+B to a 46-kD fragment. Analysis of cellular lysates by probing blots with anti- PSTAIR followed by anti-phosphotyrosine showed that in contrast to mitosis, dephosphorylation on tyrosine residues did not occur in apoptotic cells. At all timepoints after the onset of apoptosis there was no significant increase in the activation of p34cdc2 as determined in the histone H1 kinase assay. Coinduction of apoptosis and mitosis after release of cells from aphidicolin block showed that apoptosis could be induced in parallel with S-phase. The sudden breakdown of chromatin structure may be the result of detachment of the chromatin loops from their anchorage at the nuclear matrix, as bands of 50 kbp and corresponding multimers were detectable by field inversion gel electrophoresis (FIGE). In apoptotic cells all of the DNA was fragmented, but only 14% of the DNA was smaller than 50 kbp. DNA strand breaks were detected at the periphery of the condensed chromatin by in situ tailing (ISTAIL). Chromatin condensation during apoptosis appears to be due to a rapid proteolysis of nuclear matrix proteins which does not involve the p34cdc2 kinase. PMID:8051209

Adventures in Paleontology: 36 Classroom Fossil Activities (e-book)  

NSDL National Science Digital Library

Millions of years after vanishing from the Earth, dinosaurs still have the power to stir students' curiosity. Deepen that interest with Adventures in Paleontology, a series of lively hands-on activities especially for middle schoolers. This beautifully illustrated full color book features 36 activities that open students up to a variety of foundational sciences, including biology, geology, chemistry, physics, and astronomy. For example: � "How Do Fossils Form?" discusses how organisms become fossils and illustrates the concept with activities that simulate fossil-making processes. � "What Can You Learn From Fossils?" explores what fossils teach about ancient organisms. � "Mass Extinction and Meteor Collisions With Earth" discusses recently discovered links between meteor and asteroid impacts on Earth and the demise of animals like dinosaurs. Other chapters cover how to tell the age of the Earth; how dinosaurs evolved; and diversity, classification, and taxonomy. The final chapters offer humanistic perspectives on fossils in literature and art. As an attention-grabbing complement to the text, vivid full color illustrations show not just skeletons and animal tracks but also what dinosaurs probably looked like in their natural settings. Handy line drawings guide students through each step of the activities.

Interactive Whiteboard Integration in Classrooms: Active Teachers Understanding about Their Training Process  

NASA Astrophysics Data System (ADS)

With the incorporation in education of Information and Communication Technologies (ICT), especially the Interactive Whiteboard (IWB), emerges the need for a proper teacher training process due to adequate the integration and the didactic use of this tool in the classroom. This article discusses the teachers' perception on the training process for ICT integration. Its main aim is to contribute to the unification of minimum criteria for effective ICT implementation in any training process for active teachers. This case study begins from the development of a training model called Eduticom which was putted into practice in 4 schools in Catalonia, Spain. Findings indicated different teachers' needs such as an appropriate infrastructure, a proper management and a flexible training model which essentially addresses methodological and didactic aspects of IWB uses in the classroom.

THE EFFECTS OF EXERGAMING ON PHYSICAL ACTIVITY AMONG INACTIVE CHILDREN IN A PHYSICAL EDUCATION CLASSROOM  

PubMed Central

Childhood obesity, which is due in part to lack of physical activity, is a serious concern that requires the attention of the behavioral community. Although excessive video game play has been noted in the literature as a contributor to childhood obesity, newer video gaming technology, called exergaming, has been designed to capitalize on the reinforcing effects of video games to increase physical activity in children. This study evaluated the effects of exergaming on physical activity among 4 inactive children in a physical education (PE) classroom. Results showed that exergaming produced substantially more minutes of physical activity and more minutes of opportunity to engage in physical activity than did the standard PE program. In addition, exergaming was socially acceptable to both the students and the PE teacher. Exergaming appears to hold promise as a method for increasing physical activity among inactive children and might be a possible intervention for childhood obesity. PMID:21541146

Investigating the applicability of Activity-based Quantum Mechanics in a few high school physics classrooms  

NSDL National Science Digital Library

Quantum physics is not traditionally introduced in high school physics courses because of the level of abstraction and mathematical formalism associated with the subject. As part of the Visual Quantum Mechanics project, activity-based instructional units have been developed that introduce quantum principles to students who have limited backgrounds in physics and mathematics. This study investigates the applicability of one unit, Solids & Light, that introduces quantum principles within the context of learning about light emitting diodes. An observation protocol, attitude surveys, and questionnaires were used to examine the implementation of materials and student-teacher interactions in various secondary physics classrooms. Aspects of Solids & Light including the use of hands-on activities, interactive computer programs, inexpensive materials, and the focus on conceptual understanding were very applicable in the various physics classrooms observed. Both teachers and students gave these instructional strategies favorable ratings in motivating students to make observations and to learn. These ratings were not significantly affected by gender or studentsâ attitudes towards physics or computers. Solids & Light was applicable in terms of content and teaching style for some teachers. However, a mismatch of teaching styles between some instructors and the unit posed some problems in determining applicability. Observations indicated that some instructors were not able to utilize the exploratory instructional strategy of Solids & Light. Thus, Solids & Light must include additional support necessary to make the instructor comfortable with the subject matter and pedagogical style. With these revisions, Solids & Light, will have all the key components to make its implementation in a high school physics classroom a successful one.

Eliciting Metacognitive Experiences and Reflection in a Year 11 Chemistry Classroom: An Activity Theory Perspective  

NASA Astrophysics Data System (ADS)

Concerns regarding students' learning and reasoning in chemistry classrooms are well documented. Students' reasoning in chemistry should be characterized by conscious consideration of chemical phenomenon from laboratory work at macroscopic, molecular/sub-micro and symbolic levels. Further, students should develop metacognition in relation to such ways of reasoning about chemistry phenomena. Classroom change eliciting metacognitive experiences and metacognitive reflection is necessary to shift entrenched views of teaching and learning in students. In this study, Activity Theory is used as the framework for interpreting changes to the rules/customs and tools of the activity systems of two different classes of students taught by the same teacher, Frances, who was teaching chemical equilibrium to those classes in consecutive years. An interpretive methodology involving multiple data sources was employed. Frances explicitly changed her pedagogy in the second year to direct students attention to increasingly consider chemical phenomena at the molecular/sub-micro level. Additionally, she asked students not to use the textbook until toward the end of the equilibrium unit and sought to engage them in using their prior knowledge of chemistry to understand their observations from experiments. Frances' changed pedagogy elicited metacognitive experiences and reflection in students and challenged them to reconsider their metacognitive beliefs about learning chemistry and how it might be achieved. While teacher change is essential for science education reform, students are not passive players in change efforts and they need to be convinced of the viability of teacher pedagogical change in the context of their goals, intentions, and beliefs.

Effects of Animal-Assisted Activities with Guinea Pigs in the Primary School Classroom  

PubMed Central

This study investigated the effects of a classroom-based animal-assisted activities (AAA) program with guinea pigs on the social functioning of primary school children. We hypothesized that participants in the experimental condition (n = 64), compared with a waitlist control group (n = 64), would demonstrate improvements in social functioning following the program. Parents and teachers used the Social Skills Rating System (SSRS) to evaluate the social skills and problem behaviors of 128 participating children (age range = 4.8 to 12.7 years) before and after an 8-week period. Teachers also rated academic competence at both time points. Children who participated in the AAA program demonstrated significantly greater improvements in social functioning than their control group peers, as defined by greater increases in social skills (teacher SSRS) and decreases in problem behaviors (parent and teacher SSRS). There were no significant differences between the groups in academic competence. AAA participants demonstrated significant increases in social skills and decreases in problem behaviors from pre- to post-program on the teacher version of the SSRS. Control group participants did not show significant changes on these measures. These findings suggest that an AAA program with guinea pigs may be a feasible addition to the primary school classroom in order to improve social functioning. Further component analysis will be necessary to determine whether the animal is the active ingredient in AAA programs of this nature. PMID:24265514

Acquisition of the metastatic phenotype is accompanied by H2O2-dependent activation of the p130Cas signaling complex  

PubMed Central

Reactive Oxygen Species (ROS) have emerged as cellular signaling molecules and are implicated in metastatic disease by their ability to drive invasion and migration. Here we define the signaling adaptor protein p130Cas as a key redox-responsive molecular trigger that is engaged in highly invasive metastatic bladder tumor cell lines. Endogenous shifts in steady-state H2O2 that accompany the metastatic phenotype increase p130Cas phosphorylation, membrane recruitment and association with the scaffolding protein-Crk and subsequent Rac1 activation and actin reorganization. Both enzymatic and non-enzymatic scavenging of H2O2 abrogates p130Cas-dependent signaling and the migratory and invasive activity of the metastatic bladder tumor cells. Disruption of p130Cas attenuates both invasion and migration of the metastatic variant (253J-BV). 253J-BV cells displayed an increase in global thiol oxidation and a concomitant decrease in total phosphatase activity, common target proteins of active-site cysteine oxidation. The dependence of phosphatases on regulation of p130Cas was highlighted when depletion of PTPN12 enhanced p130cas phosphorylation and the migratory behavior of a non-invasive parental bladder tumor control (253J). These data demonstrate that the metastatic phenotype is accompanied by increases in steady-state H2O2 production that drive pro-migratory signaling and suggest that antioxidant-based therapeutics may prove useful in limiting bladder tumor invasiveness.

Activity Structures and the Unfolding of Problem-Solving Actions in High-School Chemistry Classrooms  

NASA Astrophysics Data System (ADS)

In this paper, we argue for a more systematic approach for studying the relationship between classroom practices and scientific practices—an approach that will likely better support the systemic reforms being promoted in the Next Generation Science Standards in the USA and similar efforts in other countries. One component of that approach is looking at how the nature of the activity structure may influence the relative alignment between classroom and scientific practices. To that end, we build on previously published research related to the practices utilized by five high-school chemistry teachers as they enacted problem-solving activities in which students were likely to generate proposals that were not aligned with normative scientific understandings. In that prior work, our analysis had emphasized micro-level features of the talk interactions and how they related to the way students' ideas were explored; in the current paper, the analysis zooms out to consider the macro-level nature of the enactments associated with the activity structure of each lesson examined. Our data show that there were two general patterns to the activity structure across the 14 lessons scrutinized, and that each pattern had associated with it a constellation of features that impinged on the way the problem space was navigated. A key finding is that both activity structures (the expansive and the open) had features that aligned with scientific practices espoused in the Next Generation Science Standards—and both had features that were not aligned with those practices. We discuss the nature of these two structures, evidence of the relationship of each structure to key features of how the lessons unfolded, and the implications of these findings for both future research and the training of teachers.

Activity Settings and Daily Routines in Preschool Classrooms: Diverse Experiences in Early Learning Settings for Low-Income Children  

PubMed Central

This paper examines activity settings and daily classroom routines experienced by 3- and 4-year-old low-income children in public center-based preschool programs, private center-based programs, and family child care homes. Two daily routine profiles were identified using a time-sampling coding procedure: a High Free-Choice pattern in which children spent a majority of their day engaged in child-directed free-choice activity settings combined with relatively low amounts of teacher-directed activity, and a Structured-Balanced pattern in which children spent relatively equal proportions of their day engaged in child-directed free-choice activity settings and teacher-directed small- and whole-group activities. Daily routine profiles were associated with program type and curriculum use but not with measures of process quality. Children in Structured-Balanced classrooms had more opportunities to engage in language and literacy and math activities, whereas children in High Free-Choice classrooms had more opportunities for gross motor and fantasy play. Being in a Structured-Balanced classroom was associated with children’s language scores but profiles were not associated with measures of children’s math reasoning or socio-emotional behavior. Consideration of teachers’ structuring of daily routines represents a valuable way to understand nuances in the provision of learning experiences for young children in the context of current views about developmentally appropriate practice and school readiness.

Using analogy role-play activity in an undergraduate biology classroom to show central dogma revision.  

PubMed

For the study of biology in an undergraduate classroom, a classroom exercise was developed: an analogy role-play to learn mechanisms of gene transcription and protein translation (central dogma). To develop the central dogma role-play exercise, we made DNA and mRNA using paper sheets, tRNA using a wire dress hanger, and amino acids using Lego® blocks (Lego System A/S, Denmark). Students were studying in the course of mathematics, physics, or chemistry, so biology was not among their usual studies. In this exercise, students perform the central dogma role-play and respectively act out nuclear matrix proteins, a transcription factor, an RNA polymerase II, an mRNA transport protein, nuclear pore proteins, a large ribosomal subunit, a small ribosomal subunit, and several amino-acyl tRNA synthetases. Questionnaire results obtained after the activity show that this central dogma role-play analogy holds student interest in the practical molecular biological processes of transcription and translation.

Space Sciences in the classroom: Educational activities of the European Space Agency  

NASA Astrophysics Data System (ADS)

Education is among the basic, mandatory activities of the European Space Agency (ESA) and aims at all educational levels, from primary school to post-graduate. The primary objective of the ESA educational activities is to enhance the literacy of young people in science and technology and to stimulate interest in STEM (Science - Technology - Engineering - Mathematics) studies and careers, using Space as a theme. The activities mostly follow the IBSE paradigm (Inquiry-Based Science Education) and also aim at the Continuous Professional Development (CPD) for teachers. The backbone supporting all educational activities is the enormous expertise of ESA in the various aspects of Space Science and Technology, like Earth Observation, Space Science (including Astronomy & Astrophysics), Human Spaceflight and Space Technology (launchers, navigation, telecommunications etc.). All educational activities, which are coordinated by the ESA Education Office, are designed for specific age groups, strive to keep the educational community informed and to provide inspirational materials for teachers and students. They can be subdivided in categories, like: Hands-on-projects, opportunities for students, support to teachers, international cooperation activities and outreach initiatives. In addition, ESA develops a variety of educational materials to support teachers in the classroom, both in classic form or on-line, through a network of dedicated websites.

Persistent At-Level Thermal Hyperalgesia and Tactile Allodynia Accompany Chronic Neuronal and Astrocyte Activation in Superficial Dorsal Horn following Mouse Cervical Contusion Spinal Cord Injury  

PubMed Central

In humans, sensory abnormalities, including neuropathic pain, often result from traumatic spinal cord injury (SCI). SCI can induce cellular changes in the CNS, termed central sensitization, that alter excitability of spinal cord neurons, including those in the dorsal horn involved in pain transmission. Persistently elevated levels of neuronal activity, glial activation, and glutamatergic transmission are thought to contribute to the hyperexcitability of these dorsal horn neurons, which can lead to maladaptive circuitry, aberrant pain processing and, ultimately, chronic neuropathic pain. Here we present a mouse model of SCI-induced neuropathic pain that exhibits a persistent pain phenotype accompanied by chronic neuronal hyperexcitability and glial activation in the spinal cord dorsal horn. We generated a unilateral cervical contusion injury at the C5 or C6 level of the adult mouse spinal cord. Following injury, an increase in the number of neurons expressing ?FosB (a marker of chronic neuronal activation), persistent astrocyte activation and proliferation (as measured by GFAP and Ki67 expression), and a decrease in the expression of the astrocyte glutamate transporter GLT1 are observed in the ipsilateral superficial dorsal horn of cervical spinal cord. These changes have previously been associated with neuronal hyperexcitability and may contribute to altered pain transmission and chronic neuropathic pain. In our model, they are accompanied by robust at-level hyperaglesia in the ipsilateral forepaw and allodynia in both forepaws that are evident within two weeks following injury and persist for at least six weeks. Furthermore, the pain phenotype occurs in the absence of alterations in forelimb grip strength, suggesting that it represents sensory and not motor abnormalities. Given the importance of transgenic mouse technology, this clinically-relevant model provides a resource that can be used to study the molecular mechanisms contributing to neuropathic pain following SCI and to identify potential therapeutic targets for the treatment of chronic pathological pain.

Geometric Reasoning in an Active-Engagement Upper-Division E&M Classroom  

NASA Astrophysics Data System (ADS)

A combination of theoretical perspectives is used to create a rich description of student reasoning when facing a highly-geometric electricity and magnetism problem in an upper-division active-engagement physics classroom at Oregon State University. Geometric reasoning as students encounter problem situations ranging from familiar to novel is described using van Zee and Manogue's (2010) ethnography of communication. Bing's (2008) epistemic framing model is used to illuminate how students are framing what they are doing and whether or not they see the problem as geometric. Kuo, Hull, Gupta, and Elby's (2010) blending model and Krutetskii's (1976) model of harmonic reasoning are used to illuminate ways students show problem-solving expertise. Sayer and Wittmann's (2008) model is used to show how resource plasticity impacts students' geometric reasoning and the degree to which students accept incorrect results.

Changes in cerebellar activity and inter-hemispheric coherence accompany improved reading performance following Quadrato Motor Training  

PubMed Central

Dyslexia is a multifactorial reading deficit that involves multiple brain systems. Among other theories, it has been suggested that cerebellar dysfunction may be involved in dyslexia. This theory has been supported by findings from anatomical and functional imaging. A possible rationale for cerebellar involvement in dyslexia could lie in the cerebellum’s role as an oscillator, producing synchronized activity within neuronal networks including sensorimotor networks critical for reading. If these findings are causally related to dyslexia, a training regimen that enhances cerebellar oscillatory activity should improve reading performance. We examined the cognitive and neural effects of Quadrato Motor Training (QMT), a structured sensorimotor training program that involves sequencing of motor responses based on verbal commands. Twenty-two adult Hebrew readers (12 dyslexics and 10 controls) were recruited for the study. Using Magnetoencephalography (MEG), we measured changes in alpha power and coherence following QMT in a within-subject design. Reading performance was assessed pre- and post-training using a comprehensive battery of behavioral tests. Our results demonstrate improved performance on a speeded reading task following one month of intensive QMT in both the dyslexic and control groups. Dyslexic participants, but not controls, showed significant increase in cerebellar oscillatory alpha power following training. In addition, across both time points, inter-hemispheric alpha coherence was higher in the dyslexic group compared to the control group. In conclusion, the current findings suggest that the combination of motor and language training embedded in QMT increases cerebellar oscillatory activity in dyslexics and improves reading performance. These results support the hypothesis that the cerebellum plays a role in skilled reading, and begin to unravel the underlying mechanisms that mediate cerebellar contribution in cognitive and neuronal augmentation.

Neural network classifications and correlation analysis of EEG and MEG activity accompanying spontaneous reversals of the Necker cube.  

PubMed

It has recently been suggested that reentrant connections are essential in systems that process complex information [A. Damasio, H. Damasio, Cortical systems for the retrieval of concrete knowledge: the convergence zone framework, in: C. Koch, J.L. Davis (Eds.), Large Scale Neuronal Theories of the Brain, The MIT Press, Cambridge, 1995, pp. 61-74; G. Edelman, The Remembered Present, Basic Books, New York, 1989; M.I. Posner, M. Rothbart, Constructing neuronal theories of mind, in: C. Koch, J.L. Davis (Eds.), Large Scale Neuronal Theories of the Brain, The MIT Press, Cambridge, 1995, pp. 183-199; C. von der Malsburg, W. Schneider, A neuronal cocktail party processor, Biol. Cybem., 54 (1986) 29-40]. Reentry is not feedback, but parallel signalling in the time domain between spatially distributed maps, similar to a process of correlation between distributed systems. Accordingly, it was expected that during spontaneous reversals of the Necker cube, complex patterns of correlations between distributed systems would be present in the cortex. The present study included EEG (n=4) and MEG recordings (n=5). Two experimental questions were posed: (1) Can distributed cortical patterns present during perceptual reversals be classified differently using a generalised regression neural network (GRNN) compared to processing of a two-dimensional figure? (2) Does correlated cortical activity increase significantly during perception of a Necker cube reversal? One-second duration single trials of EEG and MEG data were analysed using the GRNN. Electrode/sensor pairings based on cortico-cortical connections were selected to assess correlated activity in each condition. The GRNN significantly classified single trials recorded during Necker cube reversals as different from single trials recorded during perception of a two-dimensional figure for both EEG and MEG. In addition, correlated cortical activity increased significantly in the Necker cube reversal condition for EEG and MEG compared to the perception of a non-reversing stimulus. Coherent MEG activity observed over occipital, parietal and temporal regions is believed to represent neural systems related to the perception of Necker cube reversals. PMID:9593980

Extensive innate immune gene activation accompanies brain aging, increasing vulnerability to cognitive decline and neurodegeneration: a microarray study  

PubMed Central

Background This study undertakes a systematic and comprehensive analysis of brain gene expression profiles of immune/inflammation-related genes in aging and Alzheimer’s disease (AD). Methods In a well-powered microarray study of young (20 to 59?years), aged (60 to 99?years), and AD (74 to 95?years) cases, gene responses were assessed in the hippocampus, entorhinal cortex, superior frontal gyrus, and post-central gyrus. Results Several novel concepts emerge. First, immune/inflammation-related genes showed major changes in gene expression over the course of cognitively normal aging, with the extent of gene response far greater in aging than in AD. Of the 759 immune-related probesets interrogated on the microarray, approximately 40% were significantly altered in the SFG, PCG and HC with increasing age, with the majority upregulated (64 to 86%). In contrast, far fewer immune/inflammation genes were significantly changed in the transition to AD (approximately 6% of immune-related probesets), with gene responses primarily restricted to the SFG and HC. Second, relatively few significant changes in immune/inflammation genes were detected in the EC either in aging or AD, although many genes in the EC showed similar trends in responses as in the other brain regions. Third, immune/inflammation genes undergo gender-specific patterns of response in aging and AD, with the most pronounced differences emerging in aging. Finally, there was widespread upregulation of genes reflecting activation of microglia and perivascular macrophages in the aging brain, coupled with a downregulation of select factors (TOLLIP, fractalkine) that when present curtail microglial/macrophage activation. Notably, essentially all pathways of the innate immune system were upregulated in aging, including numerous complement components, genes involved in toll-like receptor signaling and inflammasome signaling, as well as genes coding for immunoglobulin (Fc) receptors and human leukocyte antigens I and II. Conclusions Unexpectedly, the extent of innate immune gene upregulation in AD was modest relative to the robust response apparent in the aged brain, consistent with the emerging idea of a critical involvement of inflammation in the earliest stages, perhaps even in the preclinical stage, of AD. Ultimately, our data suggest that an important strategy to maintain cognitive health and resilience involves reducing chronic innate immune activation that should be initiated in late midlife.

CCL21/CCR7 axis activating chemotaxis accompanied with epithelial-mesenchymal transition in human breast carcinoma.  

PubMed

Secondary lymphoid tissue chemokine (SLC/CCL21) and its receptor CCR7 have been implicated in lymph node metastasis, whereas the mechanism of which remains unclear. Epithelial-mesenchymal transition (EMT) plays an important role in invasion and migration of cancer cells. We presumed that CCL21/CCR7 axis activates EMT process to induce cancer cell invasion and metastasis. Firstly, the expressions of CCR7 and EMT markers were examined by immunohistochemical staining in the primary breast carcinoma tissues from 60 patients who underwent radical mastectomy. Then, we investigated whether CCL21/CCR7 induces EMT process during mediating cancer cell invasion or migration in vitro. By immunohistolochemistry, high expressions of CCR7, Slug and N-cadherin were seen in 60, 65, and 76.67 % of tumors, respectively, and significantly associated with lymph node metastases as well as clinical pathological stage. Furthermore, the CCR7 expression was significantly correlated to Slug and N-cadherin. In vitro, stimulating breast cancer cell lines 1428, MCF-7 and MDA-MB-231 with CCL21, the invasion and migration of tumor cells were promoted, and simultaneously, EMT phenotype of tumor cells was enhanced, including down-regulation of E-cadherin, up-regulation of Slug, Vimentin and N-cadherin at both protein and mRNA levels. Inversely, knockdown of CCR7 by shRNA suppressed tumor cell invasion, migration and EMT phenotype induced by CCL21. These results indicated that CCL21/CCR7 axis could activate EMT process during chemotaxis of breast carcinoma cells. PMID:25142946

Modulation of pineal activity during the 23rd sunspot cycle: melatonin rise during the ascending phase of the cycle is accompanied by an increase of the sympathetic tone.  

PubMed

In two groups of female CD-rats nocturnal urine (19-23 h, 23-3 h, 3-7 h) was collected at monthly intervals over 658 days (I: 1997-1999) and 494 days (II: 1999-2000) coinciding with the ascending limb (1996-2000) of the 23rd sunspot cycle (1996-2008). The excretion of 6-sulfatoxymelatonin (aMT6s: I, II) was determined as well as the ratio of noradrenaline/adrenaline (NA/A: I) reflecting the activity of the sympathetic nervous system. AMT6s was higher in II than I (19-7 h: +24%; P < 0.001; 23-3 h: +30% and 3-7 h: +17%, P < 0.001), and progressively increased (19-23 h) showing linear regressions (1: R = +0.737, P = 0.003; II: R = +0.633, 0.008) which correlated (I) with the Planetary Index (Ap: R = +0.598, P = 0.020), an established estimate of geomagnetic disturbances due to solar activity. NA/A rose at all intervals (I: 46-143%) correlating with Ap (R = +0.554-0.768; P = 0.0399-0.0013). These results indicate that melatonin secretion rises as solar activity increases during the ascending limb of a sunspot cycle accompanied by growing geomagnetic disturbances (Ap) which elevate the sympathetic tone and thus affect the pineal gland, initially stimulating the activity of arylalkylamine N-acetyltransferase and subsequently fostering the expression of N-acetylserotonin O-methyltransferase (rate-limiting enzyme for melatonin biosynthesis) if Ap increases further. The potential (patho) physiological significance of these findings is discussed and the need for a systematic continuation of such studies is emphasized. PMID:24851406

The tetramethoxyflavone zapotin selectively activates protein kinase C epsilon, leading to its down-modulation accompanied by Bcl-2, c-Jun and c-Fos decrease  

PubMed Central

Zapotin, a tetramethoxyflavone, is a natural compound with a wide spectrum of activities in neoplastic cells. Protein kinase C epsilon (PKC?) has been shown to be oncogenic, with the ability to increase cell migration, invasion and survival of tumor cells. Here we report that zapotin inhibits cell proliferation. In wild-type HeLa cells with basal endogenous expression of PKC?, the IC50 was found to be 17.9 ± 1.6 ?M. In HeLa cells overexpressing doxycycline-inducible constitutively active PKC? (HeLaPKC?A/E), the IC50 was 7.6 ± 1.3 ?M, suggesting that PKC? enhances the anti-proliferative effect of zapotin. Moreover, we found that zapotin selectively activated PKC? in comparison with other PKC family members, but attenuated doxycycline-induced PKC? expression. As a result of zapotin treatment for 6, 12 and 24 h, the doxycycline-induced levels of the two differently phosphorylated PKC? forms (87 kDa and 95 kDa) were decreased. Migration assays revealed that increasing concentrations of zapotin (from 3.5 to 15 ?M) decreased migration of HeLaPKC?A/E cells. Furthermore, zapotin significantly increased the fraction of apoptotic cells in doxycycline-induced (HeLaPKC?A/E) cells after 24 h and decreased the levels of Bcl-2, c-Jun, c-Fos. This was accompanied by a degradation of PARP-1. In summary, activation of PKC? and down-modulation of the induced PKC? level by zapotin were associated with decreased migration and increased apoptosis. These observations are consistent with the previously reported chemopreventive and chemotherapeutic action of zapotin. PMID:22381066

Development of an Interdisciplinary STEM Classroom Activity for Radio Receiver Technology  

NASA Astrophysics Data System (ADS)

Introduction The development of a mini STEM-based classroom activity designed to integrate these two fields into one project for middle school aged students is presented here. This lesson involves small groups of students constructing a small AM radio receivers. The lesson surrounding the activity focuses on both the physical nature of electromagnetic and AC waves, circuit design, practical applications to AM radio broadcasting, and research applications of radio telescopes. These tools have shown a significant increase in the lesson's primary concept understanding among 6th grade students, as well as net positive STEM awareness and enthusiasm.Content The primary teaching point for the students to consider and learn during this lesson is 'How does scientific application influence engineering design, and vice versa?' The lesson surrounds the hands-on activity of having students construct their own AM radio receiver. Wave theory and the use of radio instruments for astronomy research are also taught in a traditional lecture format. The activity is designed to complement middle school curriculum, although it has been tested and found suitable for high school and older students as well as the general public.Evaluation and ImpactThe evaluation tool that used for the student groups in this project was a Fryer chart, which is a four panel chart with the main topic listed in the center and a single question in each of the four panels. The students are asked to answer the questions in the chart before and after they participate in the lesson activity, each time in a different colored pencil so that the scores can be given to each student before and after they participated in the activity. Student scores improved from 4.5 to 17.9 out of a total of 20 possible points. This is an overall increase of 67% of the total possible points. The questions asked on the quiz cover the range of wave theory, circuit design, and scientific explanation. This factor of improvement shows that the lesson designed for this fellowship project is effective at teaching students about each of those concepts with a single teaching activity.

Long-Term Vision and Non-Vision Dominant Behavioral Deficits in the 2-VO Rats Are Accompanied by Time and Regional Glial Activation in the White Matter  

PubMed Central

The permanent occlusion of common carotid arteries (2-VO) in rats has been shown to induce progressive and long-lasting deficits in cognitive performance, however, whether these aberrant behaviors are attributed to visual dysfunction or cognitive impairment and what are the underlying mechanisms, remain controversial. In the present study, vision dominant (Morris water maze) and non-vision dominant (voice-cued fear conditioning) behavioral tests were assigned to comprehensively evaluate the influence of 2-VO lesion on cognitive behaviors. In the Morris water maze test, escape latencies of 2-VO rats were markedly increased in both hidden and unfixed visible platform tasks, which were accompanied by severe retinal damage. In the voice-cued fear conditioning test, significant reduction in the percentage of freezing behavior was observed at 60 days after 2-VO lesion. Chronic lesion by 2-VO failed to cause noticeable changes in the grey matter, as indicated by intact hippocampal and prefrontal cortical structures, sustained synaptic protein levels and glial cell numbers. In contrast, aberrant arrangement of myelinated axons was observed in the optic tract, but not in the corpus callosum and inner capsule of 2-VO rats. Concurrently, marked astrocyte proliferation and microglia activation in the optic tract occurred at 3 days after 2-VO lesion, and continued for up to 60 days. Differently, robust glial activation was observed in the corpus callosum at 3 days after 2-VO surgery, and then gradually returned to the baseline level at 14 and 60 days. Our study reported for the first time about the effect of 2-VO on the long-term cognitive impairment in the non-vision dominant fear conditioning test, which may be more applicable than the Morris water maze test for assessing 2-VO associated cognitive function. The time and region specific glial activation in the white matter may relate to retinal impairment, even behavioral deficits, in the setting of chronic cerebral hypoperfusion. PMID:24968196

Activities of X-ray binaries accompanied by a neutron star with weak magnetic field: Cir X-1, Aql X-1 and 4U 1608-52  

NASA Astrophysics Data System (ADS)

This paper is presented on X-ray activities of X-ray binaries accompanied by a neutron star with weak magnetic field. Neutron star low mass X-ray binaries (NS-LMXBs) have been well studied so far, but there are still unknown problems concerning activities of outbursts and X-ray spectral features. We can define the soft and hard states which show different spectra created from each disk structure. These states depend on the gas accretion rate causing viscosity change in the disk, whereas we have pointed out an importance of magnetic field in NS-LMXB for X-ray activities (Matsuoka & Asai 2013). Thus, we have obtained decay features occurred by a propeller effect for Aql X-1 and 4U1608-52, and thus, we have defined the propeller effect levels of these sources (Asai et al. 2013). A companion star of Cir X-1 is a star of B5~A0 type, but it has X-ray spectral feature similar to NS-LMXB as well as it produced type I X-ray bursts. A long history over 40 years of X-ray observations has provided that Cir X-1 X-ray intensities have many varieties from continuous variable fluxes with Z-type feature of NS-LMXB to recurrent outburst fluxes with Atoll-type feature on a time scale of years. Recent MAXI observations have revealed a strange sudden decay feature in some outbursts. It is difficult to explain this decay feature by the simple picture which causes by ordinary mechanisms known in NS-LMXB such as a state transition, a propeller effect and a brink due to disk irradiation (Powell et al. 2007). Therefore, we introduced new type of instability of the accretion disk in relation to stellar wind stripping effect (Asai et al. 2014) which may be common to a system consisting of a compact star and an ordinary massive star.

Classroom Activities: Simple Strategies to Incorporate Student-Centered Activities within Undergraduate Science Lectures  

PubMed Central

The traditional science lecture, where an instructor delivers a carefully crafted monolog to a large audience of students who passively receive the information, has been a popular mode of instruction for centuries. Recent evidence on the science of teaching and learning indicates that learner-centered, active teaching strategies can be more effective learning tools than traditional lectures. Yet most colleges and universities retain lectures as their central instructional method. This article highlights several simple collaborative teaching techniques that can be readily deployed within traditional lecture frameworks to promote active learning. Specifically, this article briefly introduces the techniques of: reader’s theatre, think-pair-share, roundtable, jigsaw, in-class quizzes, and minute papers. Each technique is broadly applicable well beyond neuroscience courses and easily modifiable to serve an instructor’s specific pedagogical goals. The benefits of each technique are described along with specific examples of how each technique might be deployed within a traditional lecture to create more active learning experiences.

Characterization of very-long-period seismicity accompanying summit activity at K?lauea Volcano, Hawai'i: 2007-2013  

NASA Astrophysics Data System (ADS)

Eruptive activity returned to the summit region of K?lauea Volcano, Hawai'i with the formation of the “Overlook crater” within the Halema'uma'u Crater in March 2008. The new crater continued to grow through episodic collapse of the crater walls and as of late 2013 had grown into an approximately elliptical opening with dimensions of ~ 160 × 215 m extending to a depth of ~ 200 m. Occasional weak explosive events and a persistent gas plume continued to occur through 2013. Lava was first observed in the new crater in September 2008, and through 2009 the lava level remained deep in the crater and was only occasionally observed. Since early 2010 a lava lake with fluctuating level within the Overlook crater has been nearly continuously present, and has reached to within 22 m of the Overlook crater rim. Volcanic activity at K?lauea Volcano is episodic at all time scales and the characterization of very-long-period seismicity in the band 2-100 s for the years 2007-2013 illuminates a portion of this broad spectrum of volcanic behavior. Three types of very-long-period events have been observed over this time and each is associated with distinct processes. Type 1 events are associated with vigorous degassing and occurred primarily between 2007 and 2009. Type 2 events are associated with rockfalls onto the lava lake and occurred primarily after early 2010. Both of these event types are induced by pressure and momentum changes at the top of the magma column that are transmitted downward to a source centroid ~ 1 km below the northeast corner of the Halema'uma'u Crater where the energy couples to the solid Earth at a geometrical discontinuity in the underlying dike system. Type 3 events are not related to surficial phenomena but are associated with transients in mass transfer that occur within the dike system. Very-long-period tremor has also accompanied the return of eruptive activity, with increasing amplitude associated with hours- to months-long changes in gas emission rates and summit deformation.

The Escherichia coli UVM response is accompanied by an SOS-independent error-prone DNA replication activity demonstrable in vitro.  

PubMed

UVM is an SOS-independent inducible response characterized by elevated mutagenesis at a site-specific 3, N4-ethenocytosine (epsilonC) residue borne on M13 single-stranded DNA transfected into Escherichia coli cells pretreated with DNA-damaging agents. By constructing and using E. coli strain AM124 (polA polB umuDC dinB lexA1[Ind-]), we show here that the UVM response is manifested in cells deficient for SOS induction, as well as for all four of the 'non-replicative' DNA polymerases, namely DNA polymerase I (polA), II (polB), IV (dinB) and V (umuDC). These results confirm that UVM represents a novel, previously unidentified cellular response to DNA-damaging agents. To address the question as to whether the UVM response is accompanied by an error-prone DNA replication activity, we applied a newly developed in vitro replication assay coupled to an in vitro mutation analysis system. In the assay, circular M13 single-stranded DNA bearing a site-specific lesion is converted to circular double-stranded replicative-form DNA in the presence of cell extracts and nucleotide precursors under conditions that closely mimic M13 replication in vivo. The newly synthesized (minus) DNA strand is selectively amplified by ligation-mediated polymerase chain reaction (LM-PCR), followed by a multiplex sequence analysis to determine the frequency and specificity of mutations. Replication of DNA bearing a site-specific epsilonC lesion by cell extracts from uninduced E. coli AM124 cells results in a mutation frequency of about 13%. Mutation frequency is elevated fivefold (to 58%) in cell extracts from UVM-induced AM124 cells, with C --> A mutations predominating over C --> T mutations, a specificity similar to that observed in vivo. These results, together with previously reported data, suggest that the UVM response is mediated through the induction of a transient error-prone DNA replication activity and that a modification of DNA polymerase III or the expression of a previously unidentified DNA polymerase may account for the UVM phenotype.

Electrophilic Adduction of Ubiquitin Activating Enzyme E1 by N,N-Diethyldithiocarbamate Inhibits Ubiquitin Activation and is Accompanied by Striatal Injury in the Rat  

PubMed Central

Previous studies have shown ubiquitin activating enzyme E1 to be sensitive to adduction through both Michael addition and SN2 chemistry in vitro. E1 presents a biologically important putative protein target for adduction due to its role in initiating ubiquitin based protein processing and the involvement of impaired ubiquitin protein processing in two types of familial Parkinson's disease. We tested whether E1 is susceptible to xenobiotic-mediated electrophilic adduction in vivo and explored the potential contribution of E1 adduction to neurodegenerative events in an animal model. N,N-Diethyldithiocarbamate (DEDC) was administered to rats using a protocol that produces covalent cysteine modifications in vivo and brain E1 protein adducts were characterized and mapped using shotgun LC-MS/MS. E1 activity, global and specific protein expression, and protein carbonyls were used to characterize cellular responses and injury in whole brain and dorsal striatal samples. The data demonstrate that DEDC treatment produced S-(ethylaminocarbonyl) adducts on Cys234 and Cys179 residues of E1 and decreased the levels of activated E1 and total ubiquitinated proteins. Proteomic analysis of whole brain samples identified expression changes for proteins involved in myelin structure, antioxidant response and catechol metabolism, systems often disrupted in neurodegenerative disease. Our studies also delineated localized injury within the striatum as indicated by decreased levels of tyrosine hydroxylase, elevated protein carbonyl content, increased antioxidant enzyme and ?-synuclein expression, as well as enhanced phosphorylation of tau and tyrosine hydroxylase. These data are consistent with E1 having similar susceptibility to adduction in vivo as previously reported in vitro and support further investigation into environmental agent adduction of E1 as a potential contributing factor to neurodegenerative disease. Additionally this study supports the predictive value of in vitro screens for identifying sensitive protein targets that can be used to guide subsequent in vivo experiments. PMID:22874009

Studying Earth's Environment From Space: Classroom and Laboratory Activities with Instructor Resources  

NASA Technical Reports Server (NTRS)

Standard, text-book based learning for earth, ocean, and atmospheric sciences has been limited by the unavailability of quantitative teaching materials. While a descriptive presentation, in a lecture format, of discrete satellite images is often adequate for high school classrooms, this is seldom the case at the undergraduate level. In order to address these concerns, a series of numerical exercises for the Macintosh was developed for use with satellite-derived Sea Surface Temperature, pigment and sea ice concentration data. Using a modified version of NIH Image, to analyze actual satellite data, students are able to better understand ocean processes, such as circulation, upwelling, primary production, and ocean/atmosphere coupling. Graphical plots, image math, and numerical comparisons are utilized to substantiate temporal and spatial trends in sea surface temperature and ocean color. Particularly for institutions that do not offer a program in remote sensing, the subject matter is presented as modular units, each of which can be readily incorporated into existing curricula. These materials have been produced in both CD-ROM and WWW format, making them useful for classroom or lab setting. Depending upon the level of available computer support, graphics can be displayed directly from the CD-ROM, or as a series of color view graphs for standard overhead projection.

Take-Home Challenges: Extending Discovery-Based Activities beyond the General Chemistry Classroom  

NASA Astrophysics Data System (ADS)

In an effort to more effectively integrate the experimental nature of chemistry into our students' experiences, we are developing and implementing discovery-based activities into both the laboratory and lecture components of general chemistry. Below we describe and provide an example of a "take-home challenge" intended to supplement the lecture component of the course. These take-home challenges involve the student in chemistry exploration outside of class and extend the context of content and experimentation into a nontraditional laboratory environment. Over 25 take-home challenges have been developed to date. Preliminary evaluation of the impact of the take-home challenges shows that students reporting themselves as receiving a B or C grade in the course find the challenges very useful in helping them gain a conceptual understanding of the phenomena addressed. Students earning an A grade report little or no impact on their learning. Prepared as one-page handouts, each take-home challenge begins with a scene-setting introduction followed by pertinent background information, a list of materials to be collected, and any appropriate safety precautions. The exploration component of the activity integrates leading questions with the procedural instructions to help guide the students through the discovery process and challenge them to stretch their understanding of the chemistry. After completing a take-home challenge activity, students submit written reports containing responses to the questions posed, observations of data collected, and their responses to the challenge. The accompanying sample take-home challenge activity is provided as a novel adaptation of the belch phenomenon that challenges students to experiment in order to explain the factors that account for the observed behavior. Persons interested in field testing the take-home challenges with their classes should contact the authors. Belch Bottle Challenge: What factors are responsible for the behavior of a "belch bottle"? Introductory Remarks. Have you ever belched? Belching is caused when there is an accumulation of gas in the digestive system. The "belch" occurs when the gas is released through the mouth. You can construct a "belch bottle" to imitate this action. Try this activity to find out how. Materials. 2 plastic soft-drink bottles of the same size one of the following sets of materials: potato; barrel of a Bic pen; tape (cellophane, electrical, or masking); 8-in. piece of wire, or 2 1-hole #3 stoppers; barrel of a Bic pen; tape (cellophane, electrical, or masking) water shallow tray or sink (optional) food color (optional) narrow-necked bottle made of glass (or other rigid material) Getting Ready. Cut one of the soft-drink bottles a few inches above the bottom to make a tall funnel as shown in Figure 1. Fill the second, uncut bottle half-full with water. If there is a hole in the side of the pen barrel, wrap tape around it. If 1-hole stoppers are available, slide one onto each end of the pen barrel and use this assembly to connect the cut funnel and the half-filled, uncut bottle. Alternatively, push the barrel all the way through a potato, leaving an approximately equal amount of pen barrel sticking out each side of the potato. If potato becomes lodged inside the pen barrel (that would restrict air or water flow), use a wire to push it out. Slide one end of the pen barrel into the mouth of the funnel all the way to the potato and gently screw the potato onto the thread of the funnel. Gently screw the other end of the potato onto the threads of the neck of the half-filled, uncut bottle. (See Fig. 2.) Your goal is to create an airtight seal between the funnel and the uncut soft-drink bottle. Procedure. Place the apparatus in a shallow tray or sink. Fill the funnel 3/4 full with water. (Colored water is easier to see.) Give the bottle a slight squeeze. Watch for several minutes. What do you observe? Explain your observations. Disconnect the bottle from the connector. Pour water out of the bottle until it is again only

The impact of using a veterinary medicine activity book in the classroom on fifth- and sixth-grade students' depictions of veterinarians.  

PubMed

Efforts to develop a diverse, future veterinary workforce must start as early as elementary school, when children begin to form perceptions about careers. The objective of the current project was to determine the impact of the Veterinary Medicine Activity Book: Grade 5 on fifth- and sixth-grade students' depictions of veterinarians. The book was delivered as part of the curriculum in four classrooms. Students were asked to draw a veterinarian and describe the veterinarian's activities before and after being exposed to the book. Drawings were evaluated for the gender and race/ethnicity of the illustrated veterinarian, the description of the veterinarian's activity, and animals portrayed. Significant differences were detected within three of four classrooms. In one class, after exposure to the activity book, more students drew male veterinarians and veterinarians performing an activity specifically mentioned in the book. In a second class, more students drew large animals after exposure to the activity book. In a third class, after exposure to the activity book, more students drew large animals and veterinarians performing an activity specifically mentioned in the book. Results provide preliminary evidence that children's depictions of veterinarians can be altered through use of educational materials delivered in classrooms through teacher-led discussion or formal lesson plans.

Decreased Gs alpha mRNA levels accompany the fall in Gs and adenylyl cyclase activities in compensated left ventricular hypertrophy. In heart failure, only the impairment in adenylyl cyclase activation progresses.  

PubMed Central

We have previously reported that there is a global reduction in adenylyl cyclase associated with a decrement in Gs functional activity in cardiac sarcolemma from animals with pressure overload-induced hypertrophy and heart failure. This study was performed to determine whether hypertrophy alone in the absence of heart failure is sufficient to promote these changes and whether the superimposition of heart failure intensified these changes. Basal and stimulated adenylyl cyclase and Gs activity, as determined in the S49 cyc- reconstitution assay, were measured in sarcolemma from normal (NL), left ventricular hypertrophy (LVH) and heart failure (HF) animals. Simultaneously, we measured the mRNA level encoding for the Gs alpha subunit. These studies indicate that Gs activity and Gs alpha mRNA are decreased by approximately 30% both in the failing heart and even in the heart with compensated hypertrophy before heart failure develops (Gs activity, pmol cyclic AMP/10 min per microgram, NL 4.2 +/- 0.4, LVH 3.0 +/- 0.2, HF 3.2 +/- 0.3; Gs alpha mRNA, pg/10 micrograms RNA, NL 131 +/- 9.0, LVH 104 +/- 7.4, HF 97.4 +/- 9.1; P less than 0.05 as compared with NL for LVH and HF). Accompanying this decrement in Gs activity is a fall in adenylyl cyclase, both basal and stimulated. However, we also identified a further decrease in adenylyl cyclase without any additional change in Gs or in its alpha subunit mRNA level. This is seen only in the sarcolemma from animals with heart failure as compared with those with compensated LV hypertrophy (e.g., NaF-stimulated activity, pmol cyclic AMP/min per mg, NL 420.2 +/- 17.5, LVH 347.1 +/- 29.6, HF 244.2 +/- 27.3; P less than 0.05 compared with NL for LVH and HF, P less than 0.05 compared with LVH for HF). In summary, these studies indicate that both Gs and adenylyl cyclase activities fall in parallel with the development of LV hypertrophy followed by a further decrement in adenylyl cyclase, independent of Gs, in the setting of heart failure.

Specific activation of resting T cells against tumour cells by bispecific antibodies and CD28-mediated costimulation is accompanied by Th1 differentiation and recruitment of MHC-independent cytotoxicity.  

PubMed

Specific activation of resting lymphocytes for tumour targeting can be achieved by bispecific monoclonal antibodies (bi-MoAbs) with specificity for tumour antigens and T cell-activating antigens in combination with a costimulatory anti-CD28 antibody. In this study we focus on the immunomodulatory function of an anti-CD3/CA19-9 bi-MoAb in combination with a costimulatory anti-CD28 antibody which may result not only in antigen-specific, T cell-mediated tumour cell lysis but also in recruitment of other cellular effector functions. In combination with costimulatory anti-CD28 antibodies, resting peripheral lymphocytes could be activated specifically to secrete high amounts of Th1 cytokines (IL-2, interferon-gamma (IFN-gamma)) characterizing a cellular immune response. In contrast, no IL-4 and only low amounts of IL-10 could be detected. Furthermore, bi-MoAb-mediated CA19-9-specific activation of T cells was accompanied by recruitment of MHC- and CA19-9-independent cytotoxicity, as was determined by lysis of different CA19-9-cell lines. This MHC-independent cytotxicity was mediated at least in part by activated natural killer (NK) cells, as depletion of CD16+ NK cells resulted in substantial decrease of cytotoxicity against CA19-9- targets. Our results indicate that specific activation of resting T cells with CD3-associated bi-MoAbs in combination with an anti-CD28 antibody leads to a Th1 differentiation pathway and is accompanied by recruitment of MHC-independent lymphokine-activated killer (LAK) cell cytotoxicity which can possibly be directed against a heterogeneous tumour.

Inhibition of mTORC1 by SU6656, the selective Src kinase inhibitor, is not accompanied by activation of Akt/PKB signalling in melanoma cells.  

PubMed

The mammalian target of rapamycin (mTOR) is a Ser/Thr protein kinase conserved in all eukaryotes that plays a key role in cell growth and is a central effector of several pathways regulating essential cell functions. Hyperactivation of the mTORdependent signalling pathway occurs in many human diseases and may be a selective target for their therapy. However, the dual nature of mTOR, existing in two multiprotein complexes mTORC1 and mTORC2 driven by different feedback loops, decreases the therapeutic effects of rapamycin, the specific mTOR inhibitor. In the present study we demonstrate that the mTORC1 signalling pathway is highly activated in human melanoma cells and that up-regulation of this pathway along with the growth and malignity of these cells could be suppressed by disruption of the Src activity. SU6656, the selective inhibitor of the Src kinase activity, decreased up-regulation of the mTORC1 signalling and moreover, unlike rapamycin, it did not induce the activation of Akt/PKB and its downstream targets in HBL melanoma cells. The Src protein was found to be associated with raptor in the mTORC1 complex immunoprecipitated from these cells, suggesting that the Src activity might be a new attractive target for monotherapeutic inhibition of the up-regulated mTORC1 signalling pathway.

GeoMapApp Learning Activities: Grab-and-go inquiry-based geoscience activities that bring cutting-edge technology to the classroom  

NASA Astrophysics Data System (ADS)

NSF-funded GeoMapApp Learning Activities (http://serc.carleton.edu/geomapapp) provide self-contained learning opportunities that are centred around the principles of guided inquiry. The activities allow students to interact with and analyse research-quality geoscience data to explore and enhance student understanding of underlying geoscience content and concepts. Each activity offers ready-to-use step-by-step student instructions and answer sheets that can be downloaded from the web page. Also provided are annotated teacher versions of the worksheets that include teaching tips, additional content and suggestions for further work. Downloadable pre- and post- quizzes tied to each activity help educators gauge the learning progression of their students. Short multimedia tutorials and details on content alignment with state and national teaching standards round out the package of material that comprises each "grab-and-go" activity. GeoMapApp Learning Activities expose students to content and concepts typically found at the community college, high school and introductory undergraduate levels. The activities are based upon GeoMapApp (http://www.geomapapp.org), a free, easy-to-use map-based data exploration and visualisation tool that allows students to access a wide range of geoscience data sets in a virtual lab-like environment. Activities that have so far been created under this project include student exploration of seafloor spreading rates, a study of mass wasting as revealed through geomorphological evidence, and an analysis of plate motion and hotspot traces. The step-by-step instructions and guided inquiry approach lead students through each activity, thus reducing the need for teacher intervention whilst also boosting the time that students can spend on productive exploration and learning. The activities can be used, for example, in a classroom lab with the educator present and as self-paced assignments in an out-of-class setting. GeoMapApp Learning Activities are hosted on the SERC-Carleton web site.

Pachydermoperiostosis or primary hypertrophic osteoarthropathy is an uncommon disease of acromegaloid facial feature, but characterized by unique phenotype (digital clubbing and pachydermia) and distinctive radiographic appearances like periostosis. We experienced a case with complete form of pachydermoperiostosis accompanied by heart failure. He presented with typical features consisting of clubbing with enlargement of the hand, thickening of facial skin and periosteal new bone formation involving lower leg. Echocardiography revealed severely decreased left ventricular systolic function. Treatment with medications resulted in an improvement of cardiac function and symptom. There is no previous report documenting pachydermoperiostosis accompanied by heart failure. We report that case for the first time. PMID:20661338

Geldanamycin-mediated inhibition of heat shock protein 90 partially activates dendritic cells, but interferes with their full maturation, accompanied by impaired upregulation of RelB  

PubMed Central

Background The chaperon heat shock protein 90 (HSP90) constitutes an important target for anti-tumor therapy due to its essential role in the stabilization of oncogenes. However, HSP90 is ubiquitously active to orchestrate protein turnover, chemotherapeutics that target HSP90 may affect immune cells as a significant side effect. Therefore, we asked for potential effects of pharmacological HSP90 inhibition at a therapeutically relevant concentration on human dendritic cells (DCs) as main inducers of both cellular and humoral immune responses, and on human CD4+ T cells as directly activated by DCs and essential to confer B cell help. Methods Unstimulated human monocyte-derived DCs (MO-DCs) were treated with the prototypical HSP90 inhibitor geldanamycin (GA). Based on dose titration studies performed to assess cytotoxic effects, GA was applied at a rather low concentration, comparable to serum levels of clinically used HSP90 inhibitors. The immuno-phenotype (surface markers, cytokines), migratory capacity, allo T cell stimulatory and polarizing properties (proliferation, cytokine pattern) of GA-treated MO-DCs were assessed. Moreover, effects of GA on resting and differentially stimulated CD4+ T cells in terms of cytotoxicity and proliferation were analysed. Results GA induced partial activation of unstimulated MO-DCs. In contrast, when coapplied in the course of MO-DC stimulation, GA prevented the acquisition of a fully mature DC phenotype. Consequently, this MO-DC population exerted lower allo CD4+ T cell stimulation and cytokine production. Furthermore, GA exerted no cytotoxic effect on resting T cells, but abrogated proliferation of T cells stimulated by MO-DCs at either state of activation or by stimulatory antibodies. Conclusion HSP90 inhibitors at clinically relevant concentrations may modulate adaptive immune responses both on the level of DC activation and T cell proliferation. Surprisingly, unstimulated DCs may be partially activated by that agent. However, due to the potent detrimental effects of HSP90 inhibitors on stimulated CD4+ T cells, as an outcome a patients T cell responses might be impaired. Therefore, HSP90 inhibitors most probably are not suitable for treatment in combination with immunotherapeutic approaches aimed to induce DC/T cell activation. PMID:24524692

Activation of human heat shock genes is accompanied by oligomerization, modification, and rapid translocation of heat shock transcription factor HSF1.  

PubMed

Transcriptional activity of heat shock (hsp) genes is controlled by a heat-activated, group-specific transcription factor(s) recognizing arrays of inverted repeats of the element NGAAN. To date genes for two human factors, HSF1 and HSF2, have been isolated. To define their properties as well as the changes they undergo during heat stress activation, we prepared polyclonal antibodies to these factors. Using these tools, we have shown that human HeLa cells constitutively synthesize HSF1, but we were unable to detect HSF2. In unstressed cells HSF1 is present mainly in complexes with an apparent molecular mass of about 200 kDa, unable to bind to DNA. Heat treatment induces a shift in the apparent molecular mass of HSF1 to about 700 kDa, concomitant with the acquisition of DNA-binding ability. Cross-linking experiments suggest that this change in complex size may reflect the trimerization of monomeric HSF1. Human HSF1 expressed in Xenopus oocytes does not bind DNA, but derepression of DNA-binding activity, as well as oligomerization of HSF1, occurs during heat treatment at the same temperature at which hsp gene expression is induced in this organism, suggesting that a conserved Xenopus protein(s) plays a role in this regulation. Inactive HSF1 resides in the cytoplasm of human cells; on activation it rapidly translocates to a soluble nuclear fraction, and shortly thereafter it becomes associated with the nuclear pellet. On heat shock, activatable HSF1, which might already have been posttranslationally modified in the unstressed cell, undergoes further modification. These different process provide multiple points of regulation of hsp gene expression. PMID:8455624

AT1 blockade attenuates atherosclerotic plaque destabilization accompanied by the suppression of cathepsin S activity in apoE-deficient mice.  

PubMed

Although it has been suggested that the renin-angiotensin (RA) system and cathepsins contribute to the development and vulnerability of atherosclerotic plaque, the interaction of the RA system and cathepsins is unclear. Thus, we investigated the effects of an angiotensin II type 1 receptor (AT1) antagonist, olmesartan, on the levels of cathepsins in brachiocephalic atherosclerotic plaque and plaque stabilization in apolipoprotein E (apoE)-deficient mice receiving a high-fat diet. Under a high fat diet, treatment with olmesartan (3 mg/kg per day) maintained collagen and elastin at high levels and attenuated the plaque development and cathepsin S (Cat S) level in the atherosclerotic plaque of apoE-deficient mice. The administration of olmesartan suppressed the accumulation of macrophages in plaque. Immunoreactivities of Cat S and AT1 were observed in macrophages. The amount of Cat S mRNA and the macrophage-mediated collagenolytic and elastolytic activities in cultured macrophages were increased by exposure to angiotensin II (Ang II), and these effects were diminished by olmesartan and the NADPH-oxidase inhibitor apocynin. These results suggested that Cat S derived from macrophages is involved in the mechanisms of atherosclerotic plaque vulnerability, and AT1 blocker maintained the plaque stabilization alongside the suppression of Cat S and macrophage activities.

Ajoene, a compound of garlic, induces apoptosis in human promyeloleukemic cells, accompanied by generation of reactive oxygen species and activation of nuclear factor kappaB.  

PubMed

The pharmacological role of garlic in prevention and treatment of cancer has received increasing attention, but thorough investigations into the molecular mechanisms of action of garlic compounds are rare. The present study demonstrates that ajoene, a major compound of garlic induces apoptosis in human leukemic cells, but not in peripheral mononuclear blood cells of healthy donors. The effect was dose and time dependent. Apoptosis was judged by three criteria, morphology of cells, quantification of subdiploid DNA content by flow cytometry, and detection of DNA fragmentation by gel electrophoresis. Ajoene increased the production of intracellular peroxide in a dose- and time-dependent fashion, which could be partially blocked by preincubation of the human leukemic cells with the antioxidant N-acetylcysteine. Interestingly, N-acetylcysteine-treated cells showed a 50% loss of ajoene-induced apoptosis. Moreover, ajoene was demonstrated to activate nuclear translocation of the transcription factor nuclear factor kappaB, an effect that was abrogated in N-acetylcysteine-loaded cells. These results suggested that ajoene might induce apoptosis in human leukemic cells via stimulation of peroxide production and activation of nuclear factor kappaB. This is a novel aspect in the biological profile of this garlic compound and an important step in elucidating the underlying molecular mechanisms of its antitumor action. PMID:9495804

Acclimation of Arabidopsis Leaves Developing at Low Temperatures. Increasing Cytoplasmic Volume Accompanies Increased Activities of Enzymes in the Calvin Cycle and in the Sucrose-Biosynthesis Pathway1  

PubMed Central

Photosynthetic and metabolic acclimation to low growth temperatures were studied in Arabidopsis (Heynh.). Plants were grown at 23°C and then shifted to 5°C. We compared the leaves shifted to 5°C for 10 d and the new leaves developed at 5°C with the control leaves on plants that had been left at 23°C. Leaf development at 5°C resulted in the recovery of photosynthesis to rates comparable with those achieved by control leaves at 23°C. There was a shift in the partitioning of carbon from starch and toward sucrose (Suc) in leaves that developed at 5°C. The recovery of photosynthetic capacity and the redirection of carbon to Suc in these leaves were associated with coordinated increases in the activity of several Calvin-cycle enzymes, even larger increases in the activity of key enzymes for Suc biosynthesis, and an increase in the phosphate available for metabolism. Development of leaves at 5°C also led to an increase in cytoplasmic volume and a decrease in vacuolar volume, which may provide an important mechanism for increasing the enzymes and metabolites in cold-acclimated leaves. Understanding the mechanisms underlying such structural changes during leaf development in the cold could result in novel approaches to increasing plant yield. PMID:10198098

Effectiveness of sensory processing strategies on activity level in inclusive preschool classrooms  

PubMed Central

Background The purpose of this study was to investigate the effectiveness of sensory processing strategies in improving the activity level of children with sensory integration dysfunction. Methods The study used a matching-only pretest–posttest control group design, which requires random matching of sensory integration dysfunction to the corresponding intervention group (n = 18) and control group (n = 18). The intervention group comprised 3–6-year-old children who received an 8-week school-day intervention during implementation of the theme curriculum. Results The 8-week treatment significantly reduced the activity level and foot-swinging episodes in children with sensory integration dysfunction, and obtained a medium-effect size. However, the level of improvement in the control group did not show any statistically significant change. Conclusion Sensory processing strategies could improve activity levels in children with sensory integration dysfunction. However, this study was unable to exclude a developmental effect. The social validity results show that sensory processing strategies can be integrated into the theme curriculum and improve activity levels in children. PMID:23118541

The mycotoxin beauvericin induces apoptotic cell death in H4IIE hepatoma cells accompanied by an inhibition of NF-?B-activity and modulation of MAP-kinases.  

PubMed

Beauvericin is a world-spread mycotoxin with a high toxicity in mammalian cells. However, its molecular mechanism of action is not fully understood. Using different cancer cell lines (HepG2, C6, Hct116 and H4IIE), we could show that the cyclic peptide is highly toxic (MTT assay) with IC50 values in low micromolar range. As a molecular mechanism of cell death, necrosis was detected in C6 glioma cells (PI staining), but apoptosis prevails in H4IIE hepatoma cells (caspase 3/7 activity, nuclear fragmentation). In H4IIE cells, beauvericin rapidly decreases the phosphorylation of ERK and strongly increases JNK phosphorylation, while p38 phosphorylation was not affected. Furthermore, a strong inhibition of NF-?B signalling was detectable in H4IIE cells. A screening of 21 protein kinases involved in signal transduction pathways (cell proliferation, survival, angiogenesis and metastasis) showed a selective inhibition of src kinase by beauvericin (IC50=9.8?g/ml). We suggest that beauvericin mediates its toxic effects in H4IIE cells, at least in parts, by a distinct modulation of intracellular signalling molecules. PMID:25178661

Comparison of chiropractic student scores before and after utilizing active learning techniques in a classroom setting  

PubMed Central

Objective We report the differences in final examination scores achieved by students at the culmination of two different teaching strategies in an introductory skills course. Methods Multiple choice examination scores from six consecutive academic calendar sessions over 18 months (n = 503) were compared. Two groups were used: Cohort A (n = 290) represented students who were enrolled in the course 3 consecutive academic sessions before an instructional change and Cohort B (n = 213) included students who were enrolled in 3 consecutive academic sessions following the instructional change, which included a more active learning format. Statistical analyses used were 2-tailed independent t-test, one-way ANOVA, Tukey's honestly significant difference (HSD), and effect size. Results The 2-tailed independent t-test revealed a significant difference between the two groups (t = ?3.71, p < .001; 95% confidence interval [CI] 1.29–4.20). Significant difference was found in the highest performing subgroup compared to the lowest performing subgroup in Cohort A (F = 3.343, p = .037). For Cohort A subgroups 1 and 2, Tukey's HSD was p < .028. In Cohort B, no difference was found among subgroups (F = 1.912, p = .150, HSD p > .105). Conclusion Compared to previous versions of the same course taught by the same instructor, the students in the new course design performed better, suggesting that using active learning techniques helps improve student achievement.

Gaining A Geological Perspective Through Active Learning in the Large Lecture Classroom  

NASA Astrophysics Data System (ADS)

NATS 101 A Geological Perspective is a general education course taken by non science majors. We offer 600 seats per semester, with four large lecture sections taught by different faculty members. In the past we have offered optional once a week study groups taught by graduate teaching assistants. Students often feel overwhelmed by the science and associated jargon, and many are prone to skipping lectures altogether. Optional study groups are only attended by ~50% of the students. Faculty members find the class to be a lot of work, mainly due to the grading it generates. Activities given in lecture are often short multiple choice or true false assignments, limiting the depth of understanding we can evaluate. Our students often lack math and critical thinking skills, and we spend a lot of time in lecture reintroducing ideas students should have already gotten from the text. In summer 2007 we were funded to redesign the course. Our goals were to 1) cut the cost of running the course, and 2) improve student learning. Under our redesign optional study groups were replaced by once a week mandatory break out sessions where students complete activities that have been introduced in lecture. Break out sessions substitute for one hour of lecture, and are run by undergraduate preceptors and graduate teaching assistants (GTAs). During the lecture period, lectures themselves are brief with a large portion of the class devoted to active learning in small groups. Weekly reading quizzes are submitted via the online course management system. Break out sessions allow students to spend more time interacting with their fellow students, undergraduate preceptors, and GTAs. They get one on one help in break out sessions on assignments designed to enhance the lecture material. The active lecture format means less of their time is devoted to listening passively to a lecture, and more time is spent peer learning an interacting with the instructor. Completing quizzes online allows students more freedom in when and where they complete their work, and we provide instant feedback on their submitted work. The University of Wyoming Cognition in Astronomy, Physics and Earth sciences Research (CAPER) Team, who specialize in project evaluation, are leading the evaluation effort. We are comparing pre-test to post-test gains on the Geoscience Concept Inventory and Attitudes Toward Science surveys before and after the redesign, and inductive analysis of student interviews and reflective writing that describe student perceptions of the modified learning environment. The redesign has cut the cost of the class per student by more than half. This was achieved primarily in two ways: 1) by greatly reducing the number of hours spent by faculty and graduate teaching assistants on preparation, class time, and grading; and 2) reducing the number of graduate teaching assistants required for the class and replacing many of them with undergraduate preceptors. Undergraduate preceptors are not paid, but receive academic credit for their teaching service. The savings from the redesign is used to allow faculty more time to work on institutional priorities.

Does Structured Quizzing with Process Specific Feedback Lead to Learning Gains in an Active Learning Geoscience Classroom?  

NASA Astrophysics Data System (ADS)

There is a great realization that efficient teaching in the geosciences has the potential to have far reaching effects in outreach to decision and policy makers (Herbert, 2006; Manduca & Mogk, 2006). This research in turn informs educators that the geosciences by the virtue of their highly integrative nature play an important role in serving as an entry point into STEM disciplines and helping developing a new cadre of geoscientists, scientists and a general population with an understanding of science. Keeping these goals in mind we set to design introductory geoscience courses for non-majors and majors that move away from the traditional lecture models which don't necessarily contribute well to knowledge building and retention ((Handelsman et al., 2007; Hake, 1997) to a blended active learning classroom where basic concepts and didactic information is acquired online via webquests, lecturettes and virtual field trips and the face to face portions of the class are focused on problem solving exercises. The traditional way to ensure that students are prepared for the in-class activity is to have the students take a quiz online to demonstrate basic competency. In the process of redesign, we decided to leverage the technology to build quizzes that are highly structured and map to a process (formation of divergent boundaries for example) or sets of earth processes that we needed the students to know before in-class activities. The quizzes can be taken multiple times and provide process specific feedback, thus serving as a heuristic to the students to ensure they have acquired the necessary competency. The heuristic quizzes were developed and deployed over a year with the student data driving the redesign process to ensure synchronicity. Preliminary data analysis indicates a positive correlation between higher student scores on in-class application exercises and time spent on the process quizzes. An assessment of learning gains also indicate a higher degree of self efficacy among students who took the quizzes multiple times vs. the students who took the quizzes just enough times to ensure a passing grade.

The efficacy of World Wide Web-mediated microcomputer-based laboratory activities in the high school physics classroom  

NASA Astrophysics Data System (ADS)

This research project examined the efficacy of an online microcomputer-based laboratory based (MBL) physics unit. One hundred and fifty physics students from five high schools in North Carolina were divided into online and classroom groups. The classroom group completed the MBL unit in small groups with assistance from their teachers. The online groups completed the MBL unit in small groups using a website designed for this project for guidance. Pre- and post-unit content specific tests and surveys were given. Statistical analysis of the content tests showed significant development of conceptual understanding by the online group over the course of the unit. There was not a significant difference between the classroom and online group with relation to the amount of conceptual understanding developed. Correlations with post-test achievement showed that pre-test scores and math background were the most significant correlates with success. Computer related variables, such as computer comfort and online access, were only mildly correlated with the online group. Students' views about the nature of physics were not well developed prior to the unit and did not significantly change over the course of the unit. Examination of the students' physics conceptions after instruction revealed common alternative conceptions such as confusing position and velocity variables and incorrect interpretations of graphical features such as slope.

An analysis of science instruction in the fifth-grade science classroom: Investigating activity-based instruction with student-generated discussion  

NASA Astrophysics Data System (ADS)

The purpose of this study was to determine the extent to which debriefing impacts the level of cognitive understanding among students in the fifth-grade science classroom. This mixed methods study involved two fifth-grade science classrooms (N = 39) in a one month exploration of rocks and minerals. Two fifth-grade science classrooms participated in a unit using identical content, but had different pedagogical orientations. The experimental class was taught using the "Do-Talk-Do-Debrief" instructional method and the control class was taught using the "Do-Talk-Do" instructional method without the "Debrief" (metacognitive component). Research for the quantitative portion of this study was conducted using a pretest-posttest control-group design. The design was used to test the hypothesized relationship between an activity-based instructional method with debriefing and students' achievement. Two intact, equivalent fifth-grade classes were randomly assigned to treatment and control conditions. Prior to the beginning of the study, a researcher-developed pretest was administered to all participants to assess the students' prior knowledge of rocks and minerals. A posttest measure was given to the participants upon conclusion of the unit to measure knowledge and understanding. Following the posttest, the participants did not receive additional instruction over rocks and minerals. A similar posttest was administered to both groups two weeks later as an added measure for retention. A t-test for independent samples was used to examine differences on the pretest between the experimental and control groups. Likewise, a t-test was used to compare the mean scores on the first posttest (achievement). A separate t-test was conducted on the second posttest (retention) and was followed by a Pearson Product Moment Correlation, conducted by group. Research for the qualitative portion of this study involved classroom observations throughout the rock and mineral unit followed by a teacher interview. Observations were made in two fifth-grade classrooms and Flanders' Categories for Interaction Analysis was used as a framework for observing the level of social interaction. The observations were transcribed and developed into a "thick" record as suggested by Dr. Phil Carspecken's stages of qualitative research. Member checking and peer debriefing techniques were employed to increase the trustworthiness of the study. The quantitative data suggested science achievement of fifth-grade science students who learned through activity-based instruction with debriefing was statistically significantly higher than the science achievement of fifth-grade science students who learned through activity-based instruction without debriefing (p<.01), as measured by the first posttest. Also, student retention as measured by fifth-grade science students who learned through activity-based instruction was statistically significantly higher than fifth-grade science students who learned through activity-based instruction without debriefing (p<.01), as measured by the second posttest. Additionally, the effect sizes for achievement and retention were very large and educationally meaningful. Activity-based instruction enhanced with debriefing resulted in a deeper construction of knowledge and retention of understanding.

Induction of CD11a/leukocyte function antigen-1 and CD54/intercellular adhesion molecule-1 on hairy cell leukemia cells is accompanied by enhanced susceptibility to T-cell but not lymphokine-activated killer-cell cytotoxicity.  

PubMed

Some B-cell neoplasms, including hairy cell leukemia (HCL), lack expression of the adhesion molecule leukocyte function antigen-1 (LFA-1/CD11a). Additionally, HCL cells express relatively low amounts of intercellular adhesion molecule-1 (ICAM-1/CD54) and may therefore be an inappropriate target for recognition by T cells or lymphokine-activated killer (LAK) cells. We tested whether these molecules were inducible on HCL cells and if induction would lead to enhanced susceptibility to lysis by LAK cells or cytolytic T cells. CD11a expression was induced by incubation with interferon-alpha (IFN-alpha) or interleukin-4. CD54 was induced by culturing the cells irrespectively of the addition of cytokines. Expression of CD11a and CD54 did not enhance susceptibility to either autologous or allogeneous LAK cells. However, induction of these adhesion molecules was accompanied by enhanced susceptibility to lysis by cytotoxic T lymphocyte clones. This lysis could be reversed by the addition of anti-CD11a and anti-CD54 antibodies. Finally, we monitored the expression of CD11a and CD54 on HCL cells from patients during IFN-alpha therapy. In one of four patients monitored, we observed rapid in vivo induction of CD11a and CD54 on the leukemic cells during IFN-alpha therapy. These studies provide a model for studying immunosurveillance in HCL. PMID:1352710

The Zooniverse: Cutting Edge Scientific Research in the Classroom  

NASA Astrophysics Data System (ADS)

Increasingly scientists and researchers from a multitude of disciplines are finding themselves inundated with more data than they could possibly interpret in a lifetime. Computers can be used entirely or partially for some data analysis; but there are some tasks that are currently best suited to human eyes, ears and brains. Zooniverse (www.zooniverse.org) invites members of the public to help researchers analyze and interpret data. To date, hundreds of thousands of volunteers have been involved in classifying images, interpreting sounds and transcribing texts. Zooniverse citizen scientists are providing valuable analyses across a variety of fields, from the hunt for exoplanets in Planet Hunters (planethunters.org) to the transcription of Greek papyri in Ancient Lives (ancientlives.org). Multiple academic publications have resulted from the combined efforts of the Zooniverse community and science teams demonstrating that citizen science is more than ever becoming a well-established method of doing research. Unlike most research projects the data, analysis and interactions with the science teams have an established and visible online presence through the project website and related discussion sites and blogs. These in themselves provide a valuable classroom resource, an opportunity for free and easy access to cutting edge scientific research. Anecdotal evidence exists that teacher can and already do use Zooniverse projects. By providing a rich and varied scaffolding to accompany the Zooniverse projects the opportunity exists for bringing citizen scientists to a wider classroom audience. An audience that may include non-specialist teachers, who require additional support to deliver challenging content, or time strapped educators who haven't the time to develop their own accompanying resources to weave Zooniverse projects into their lessons. During the session we will discuss the recent Zooniverse projects specifically designed to support and promote classroom adoption locally, within the Chicago Public School (CPS) system and nationally within the United States. Introducing ZooTeach, a website where educators may share and search for lesson plans, activities, and resources. Beyond a simple lesson plan repository, ZooTeach is a community where educators are encouraged to modify, comment on, and otherwise actively participate in the educational efforts of Zooniverse. Teacher workshops run at Adler have and will continue to have the dual effect of promoting the Zooniverse and it's educational effort while increasing the pool of resources available nationally via ZooTeach. In house developed teacher guides and interactive tools allowing for the collection and manipulation of data will further enhance the classroom education experience and further lower the bar for entry into the world of citizen science.

Classroom Solar Calendar  

NSDL National Science Digital Library

In this activity, students engage in an ongoing investigation to find patterns of sunlight and shadow in a classroom (or any room that gets sunlight) at different times of the day and different times of the year. Students look for repeating patterns, keep a log to describe and sketch observations of when and where certain easily recognized patters appear and turn the room into a solar calendar that may survive into the future for other classes to use. Part 1 of this activity requires occasional note-taking and casual observation over the course of a day.

Effects of participation in inquiry science workshops and follow-up activities on middle school science teachers' content knowledge, teacher-held misconceptions, and classroom practices  

NASA Astrophysics Data System (ADS)

An important aspect of developing science literacy for all students is developing science-literate teachers. With the implementation of the No Child Left Behind Act, many middle school teachers found themselves in a position where they were no longer qualified to teach middle school science. This study was designed to help science teachers increase their science content knowledge, identify and resolve misconceptions/errors they may have, and assist them in their teaching by providing strategies for inquiry-based teaching, science laboratory exercises, and science equipment. Teachers enrolled in biology courses offered by the Rocky Mountain Middle School Math and Science Partnership participated in this study. They were required to take pre-, post-, and follow-up assessments over course concepts, complete a survey over their background and teaching pedagogy, and be observed teaching in their classrooms for three class periods followed by an interview after each observation. The results included key findings: (1) These assessments indicated that science teachers can increase their science content knowledge by attending high-quality professional development courses designed to help increase basic science content knowledge on science content. (2) Teachers held numerous misconceptions as shown by the assessments and classroom observations. Some were resolved, some that appeared to be resolved at the time of the post test reappeared again on the follow-up test, and some were not resolved. (3) Teacher observations showed that they did use science equipment provided by the course instructors and they taught the content from the Biology course where appropriate. Teachers teaching classes other than biology demonstrated their ability to teach inquiry science by employing inquiry activities and teaching with a "scientific method" approach.

A randomized controlled pilot trial of classroom-based mindfulness meditation compared to an active control condition in sixth-grade children.  

PubMed

The current study is a pilot trial to examine the effects of a nonelective, classroom-based, teacher-implemented, mindfulness meditation intervention on standard clinical measures of mental health and affect in middle school children. A total of 101 healthy sixth-grade students (55 boys, 46 girls) were randomized to either an Asian history course with daily mindfulness meditation practice (intervention group) or an African history course with a matched experiential activity (active control group). Self-reported measures included the Youth Self Report (YSR), a modified Spielberger State-Trait Anxiety Inventory, and the Cognitive and Affective Mindfulness Measure -Revised. Both groups decreased significantly on clinical syndrome subscales and affect but did not differ in the extent of their improvements. Meditators were significantly less likely to develop suicidal ideation or thoughts of self-harm than controls. These results suggest that mindfulness training may yield both unique and non-specific benefits that are shared by other novel activities. PMID:24930819

Early integration of the individual student in academic activities: a novel classroom concept for graduate education in molecular biophysics and structural biology  

PubMed Central

Background A key challenge in interdisciplinary research is choosing the best approach from a large number of techniques derived from different disciplines and their interfaces. Results To address this challenge in the area of Biophysics and Structural Biology, we have designed a graduate level course to teach students insightful use of experimental biophysical approaches in relationship to addressing biological questions related to biomolecular interactions and dynamics. A weekly seminar and data and literature club are used to compliment the training in class. The course contains wet-laboratory experimental demonstration and real-data analysis as well as lectures, grant proposal preparation and assessment, and student presentation components. Active student participation is mandatory in all aspects of the class. Students prepare materials for the class receiving individual and iterative feedback from course directors and local experts generating high quality classroom presentations. Conclusions The ultimate goal of the course is to teach students the skills needed to weigh different experimental approaches against each other in addressing a specific biological question by thinking and executing academic tasks like faculty.

Metastatic Basal Cell Carcinoma Accompanying Gorlin Syndrome  

PubMed Central

Gorlin-Goltz syndrome or basal cell nevus syndrome is an autosomal dominant syndrome characterized by skeletal anomalies, numerous cysts observed in the jaw, and multiple basal cell carcinoma of the skin, which may be accompanied by falx cerebri calcification. Basal cell carcinoma is the most commonly skin tumor with slow clinical course and low metastatic potential. Its concomitance with Gorlin syndrome, resulting from a mutation in a tumor suppressor gene, may substantially change morbidity and mortality. A 66-year-old male patient with a history of recurrent basal cell carcinoma was presented with exophthalmus in the left eye and the lesions localized in the left lateral orbita and left zygomatic area. His physical examination revealed hearing loss, gapped teeth, highly arched palate, and frontal prominence. Left orbital mass, cystic masses at frontal and ethmoidal sinuses, and multiple pulmonary nodules were detected at CT scans. Basal cell carcinoma was diagnosed from biopsy of ethmoid sinus. Based on the clinical and typical radiological characteristics (falx cerebri calcification, bifid costa, and odontogenic cysts), the patient was diagnosed with metastatic skin basal cell carcinoma accompanied by Gorlin syndrome. Our case is a basal cell carcinoma with aggressive course accompanying a rarely seen syndrome. PMID:25506011

NASA Classroom Bioreactor  

NASA Technical Reports Server (NTRS)

Exploration of space provides a compelling need for cell-based research into the basic mechanisms that underlie the profound changes that occur in terrestrial life that is transitioned to low gravity environments. Toward that end, NASA developed a rotating bioreactor in which cells are cultured while continuously suspended in a cylinder in which the culture medium rotates with the cylinder. The randomization of the gravity vector accomplished by the continuous rotation, in a low shear environment, provides an analog of microgravity. Because cultures grown in bioreactors develop structures and functions that are much closer to those exhibited by native tissue than can be achieved with traditional culture methods, bioreactors have contributed substantially to advancing research in the fields of cancer, diabetes, infectious disease modeling for vaccine production, drug efficacy, and tissue engineering. NASA has developed a Classroom Bioreactor (CB) that is built from parts that are easily obtained and assembled, user-friendly and versatile. It can be easily used in simple school settings to examine the effect cultures of seeds or cells. An educational brief provides assembly instructions and lesson plans that describes activities in science, math and technology that explore free fall, microgravity, orbits, bioreactors, structure-function relationships and the scientific method.

Mechanical Surface Waves Accompany Action Potential Propagation  

E-print Network

Many studies have shown that a mechanical displacement of the axonal membrane accompanies the electrical pulse defining the Action Potential (AP). Despite a large and diverse body of experimental evidence, there is no theoretical consensus either for the physical basis of this mechanical wave nor its interdependence with the electrical signal. In this manuscript we present a model for these mechanical displacements as arising from the driving of surface wave modes in which potential energy is stored in elastic properties of the neuronal membrane and cytoskeleton while kinetic energy is carried by the axoplasmic fluid. In our model these surface waves are driven by the traveling wave of electrical depolarization that characterizes the AP, altering the compressive electrostatic forces across the membrane as it passes. This driving leads to co-propagating mechanical displacements, which we term Action Waves (AWs). Our model for these AWs allows us to predict, in terms of elastic constants, axon radius and axoplasmic density and viscosity, the shape of the AW that should accompany any traveling wave of voltage, including the AP predicted by the Hodgkin and Huxley (HH) equations. We show that our model makes predictions that are in agreement with results in experimental systems including the garfish olfactory nerve and the squid giant axon. We expect our model to serve as a framework for understanding the physical origins and possible functional roles of these AWs in neurobiology.

Dedifferentiation of Arabidopsis thaliana cells is accompanied by a strong decrease in RNA polymerase II transcription activity and poly(A+) RNA and 25S rRNA eradication from the cytoplasm.  

PubMed

The mechanisms of plant cell dedifferentiation and the acquisition of totipotency are poorly understood. One of the methods to induce the dedifferentiation process in plant cells is simple and requires the removal of the cell wall. After cell wall removal in protoplasts, large-scale chromatin decondensation is observed (Tessadori et al. in J Cell Sci 120:1200-1208, 2007). Here, we show that in Arabidopsis thaliana protoplasts, despite chromatin decondensation, RNA polymerase II transcriptional activity is reduced. The subsequent investigated stages displayed a clear decrease in the quantity of 25S ribosomal RNA (rRNA) first and then poly(A+) RNA, particularly in the cytoplasm. Therefore, the reduced transcription activity and the removal of these RNA transcripts from the cytoplasm is a crucial process in obtaining totipotency in plant cells. After the cytoplasm cleaning of transcripts derived from mesophyll cells, we observed the resynthesis of these RNAs. An increase in the amount of examined molecules to a level similar to that in differentiated mesophyll cells precedes the divisions of already undifferentiated cells. In this work, we show changes in RNA polymerase II transcription dynamics and the quantity of poly(A+) RNA and 25S rRNA during dedifferentiation and re-entry into the cell cycle. PMID:25248757

Although most of sacral perineural cysts are asymptomatic, some may produce symptoms. Specific radicular pain may be due to distortion, compression, or stretching of nerve root by a space occupying cyst. We report a rare case of S1 radiculopathy caused by sacral perineural cyst accompanying disc herniation. The patient underwent a microscopic discectomy at L5-S1 level. However, the patient's symptoms did not improved. The hypesthesia persisted, as did the right leg pain. Cyst-subarachnoid shunt was set to decompress nerve root and to equalize the cerebrospinal fluid pressure between the cephalad thecal sac and cyst. Immediately after surgery, the patient had no leg pain. After 6 months, the patient still remained free of leg pain. PMID:19352483

Cystic lesions accompanying extra-axial tumours.  

PubMed

We examined the mechanism of cyst formation in extra-axial tumours in the central nervous system (CNS). Cyst fluid, cerebrospinal fluid (CSF) and blood plasma were analysed in eight patients with nine peritumoral cysts: four with meningiomas, two with intracranial and two spinal intradural schwannomas. Measuring concentrations of various proteins [albumin, immunoglobulin G (IgG), IgA, alpha 2-macroglobulin and IgM] in cyst fluid, CSF and blood plasma provides insight into the state of the semipermeability of the blood-brain barrier (BBB) and blood-cerebrospinal fluid barrier. Peritumoral cysts accompanying intra-axial brain tumours are the end result of disruption of the BBB and oedema formation. Unlike intra-axial tumours which lie embedded within nervous tissue, extra-axial tumours tend to be separated from nervous tissue by arachnoid and pia mater. High concentrations of proteins were measured in the cyst fluid, approaching blood plasma levels, suggesting a local barrier disruption, and passage across the arachnoid, pia mater and cortical/medullary layer into the CNS parenchyma, leaving the protein concentrations of CSF practically unchanged. We confirmed that very high concentrations of protein are to be found in tumour cysts, plasma proteins forming almost 90% of the total protein in the cyst. We review current hypotheses on the pathogenesis of cysts accompanying neoplasms, particularly meningiomas and schwannomas, and conclude that the majority of proteins in cyst fluid in extra-axial, intradural meningiomas and schwannomas are plasma proteins. This provides a strong argument for pathogenesis of extra-axial intradural tumour cysts in favour of leakage of plasma proteins out of the tumour vessels into the nervous tissue. PMID:9987761

Everyday classroom assessment practices in science classrooms in Sweden  

NASA Astrophysics Data System (ADS)

The focus of this study is to examine to what extent and in what ways science teachers practice assessment during classroom interactions in everyday activities in an upper-secondary school in Sweden. We are science teachers working now with a larger research project on assessment in science education that seeks to examine teachers' assessment practices in the upper-secondary school. Framing questions include: are teachers performing an integrated assessment of students' skills as the national curriculum mandates? If so, what do the instructional discourses look like in those situations and what are students' experiences regarding their agency on learning and assessment? We emphasize the social, cultural and historic character of assessment and sustain a situated character of learning instead of the notion that learning is "stored inside the head". Teacher led lessons in three science classrooms were video-recorded and analyzed by combining ethnographic and discourse methods of analysis. Both methods are appropriate to the theoretical foundation of our approach on learning and can give some answers to questions about how individuals interact socially, how their experience is passed on to next generations through language and how language use may reveal cultural changes in the studied context. Making the study of action in a classroom the focal point of sociocultural analysis supports the examination of assessment processes and identification of the social roles in which teachers and students are immersed. Such an approach requires observations of how teachers act in authentic teaching situations when they interact with their students in classroom making possible to observe negotiation processes, agencies when both teachers and students are involved in every-day activities. Our study showed that teachers mostly ignored students' questions and that students solved their own problems by helping each other. Teachers did not provide opportunities for students to discuss or argue scientific issues as the national science curriculum stipulates. We found that traditional assessment methods, such as tests, examinations and assignments were the most common methods used to assess and grade students' learning. Different aspects of knowledge stipulated in the national Swedish curriculum, such as lifelong learning, stimulation to students' creativity, curiosity as well as their wish to explore and convert new ideas into action, and find solutions to problems, were restricted by teachers' discourses. The observed teachers' learning and assessment practices constrain students' agency leading to students' silence consequently hindering students' development.

A Stream Ecosystem in the Classroom  

NSDL National Science Digital Library

To build a model of the world of nature is never an easy task. In this case the lotic ecosystem for the classroom is no exception. However, with the right materials, some time, and student involvement you can have an operational classroom ecosystem, complete with organisms, physical environment, interactions and relationships, and natural succession. The classroom stream ecosystem provides a focus for biology class projects, lessons, experiments and research. It provides students with a sense of ownership in the class if they are involved in the development of the system early in the school year. I have found students simply standing and observing, conversing about their ideas, and actively wondering what is going on in the stream on a daily basis. The model is a magnet for student curiosity. If you have a chance to build one and use it, I recommend it strongly, and wish you luck in your new quest to make biology real and relevant to your students.

Extinction of Oct-3/4 gene expression in embryonal carcinoma [times] fibroblast somatic cell hybrids is accompanied by changes in the methylation status, chromatin structure, and transcriptional activity of the Oct-3/4 upstream region  

SciTech Connect

The OCT-3/4 gene provides an excellent model system with which to study the extinction phenomenon in somatic cell hybrids. The molecular mechanism that underlies the extinction of a tissue-specific transcription factor in somatic cell hybrides is evaluated and compared with its down-regulation in retinoic acid treated embryonal carcinoma cells. This study draws a connection between the shutdown of OCT-3/4 expression in retinoic acid (RA)-differentiated embryonal carcinoma (EC) cells and its extinction in hybrid cells. This repression of OCT-3/4 expression is achieved through changes in the methylation status, chromatin structure, and transcriptional activity of the OCT-3/4 upstream regulatory region. 59 refs.

Review: Regional land subsidence accompanying groundwater extraction  

NASA Astrophysics Data System (ADS)

The extraction of groundwater can generate land subsidence by causing the compaction of susceptible aquifer systems, typically unconsolidated alluvial or basin-fill aquifer systems comprising aquifers and aquitards. Various ground-based and remotely sensed methods are used to measure and map subsidence. Many areas of subsidence caused by groundwater pumping have been identified and monitored, and corrective measures to slow or halt subsidence have been devised. Two principal means are used to mitigate subsidence caused by groundwater withdrawal—reduction of groundwater withdrawal, and artificial recharge. Analysis and simulation of aquifer-system compaction follow from the basic relations between head, stress, compressibility, and groundwater flow and are addressed primarily using two approaches—one based on conventional groundwater flow theory and one based on linear poroelasticity theory. Research and development to improve the assessment and analysis of aquifer-system compaction, the accompanying subsidence and potential ground ruptures are needed in the topic areas of the hydromechanical behavior of aquitards, the role of horizontal deformation, the application of differential synthetic aperture radar interferometry, and the regional-scale simulation of coupled groundwater flow and aquifer-system deformation to support resource management and hazard mitigation measures.
