Sample classroom activities based on climate science  

NASA Astrophysics Data System (ADS)

We present several activities developed for the middle school education based on a climate science. The first activity was designed to teach about the ocean acidification. A simple experiment can prove that absorption of CO2 in water increases its acidity. A liquid pH indicator is suitable for the demonstration in a classroom. The second activity uses data containing coordinates of a hurricane position. Pupils draw a path of a hurricane eye in a tracking chart (map of the Atlantic ocean). They calculate an average speed of the hurricane, investigate its direction and intensity development. The third activity uses pictures of the Arctic ocean on September when ice extend is usually the lowest. Students measure the ice extend for several years using a square grid printed on a plastic foil. Then they plot a graph and discuss the results. All these activities can be used to improve the natural science education and increase the climate change literacy.

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.

BackgroundThere is increasing evidence for the association between physical activity, cardiovascular fitness, fatness, and cognitive function during childhood and adolescence. Evidence also suggests that these variables are linked to academic achievement. Classroom-based physical activity provides a viable approach to improve fitness, body mass index (BMI), cognitive function, and ultimately academic achievement.

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. [J Nurs Educ. 2013;52(11):653-656.]. PMID:24127175

Source mechanism of very-long-period signals accompanying dome growth activity at Merapi volcano, Indonesia  

USGS Publications Warehouse

Very-long-period (VLP) pulses with period of 6-7s, displaying similar waveforms, were identified in 1998 from broadband seismographs around the summit crater. These pulses accompanied most of multiphase (MP) earthquakes, a type of long-period event locally defined at Merapi Volcano. Source mechanisms for several VLP pulses were examined by applying moment tensor inversion to the waveform data. Solutions were consistent with a crack striking ???70?? and dipping ???50?? SW, 100m under the active dome, suggest pressurized gas transport involving accumulation and sudden release of 10-60 m3 of gas in the crack over a 6s interval.

The Physics Classroom: Name That Motion Activity Sheet  

NSDL National Science Digital Library

This unique activity presents eleven interactive challenges designed to help students understand the language of motion. Each challenge requires the student to match the motion of an animated car to the correct verbal description of that motion. After all matches have been completed, students check their answers and try again in case of a mismatch. Editor's Note: This activity is ideal for promoting constructivism in the secondary science classroom. It offers learners a low-risk environment for building their own understanding of velocity as a vector quantity, positive and negative acceleration, constant speed, and constant acceleration. It can be adapted for use in both middle and high school. The activity sheet allows teachers to insert the animation quickly into existing lessons. This resource is part of The Physics Classroom web site, a growing collection of resources for teachers and learners of introductory physics.

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.

Activation of chicken liver dihydrofolate reductase by urea and guanidine hydrochloride is accompanied by conformational change at the active site.  

PubMed Central

It has been reported that the activation of dihydrofolate reductase (DHFR) from L1210 mouse leukaemia cells by KCl or thiol modifiers is accompanied by increased digestibility by proteinases [Duffy, Beckman, Peterson, Vitols and Huennekens (1987) J. Biol. Chem. 262, 7028-7033], suggesting a loosening up of the general compact structure of the enzyme. In the present study, the peptide fragments liberated from the chicken liver enzyme by digestion with trypsin in dilute solutions of urea or guanidine hydrochloride (GuHCl) have been separated by FPLC and sequenced. The sequences obtained are unique when compared with the known sequence of DHFR and thus allow the points of proteolytic cleavage identified for the urea- and GuHCl-activated enzyme to be at or near the active site. It was also indicated by the enhanced fluorescence of 2-p-toluidinylnaphthalene 6-sulfonate that conformational changes at the active site in dilute GuHCl parallel GuHCl activation. The above results indicate that the activation of DHFR in dilute denaturants is accompanied by a loosening up of its compact structure especially at or near the active site, suggesting that the flexibility at its active site is essential for the full expression of its catalytic activity.

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.

Activity systems in the inquiry classroom  

NASA Astrophysics Data System (ADS)

Inquiry science, as called for by reform-minded organizations such as the National Research Council (1996), offers a platform with the potential for introducing all students to the practice of science while maintaining focus on key concepts and theories. This project followed two small groups as they completed an inquiry unit on genetics at a Midwestern high school. I investigated whether levels of student-to-teacher, student-to-student, student-apparatus, and student-concept connections were approximately equal across all students in each of the two groups. I found differences among students in levels of student-to-teacher, student-to-student, and student-concept connections. From a situated idiopathic perspective, these differences may indicate different levels of opportunity-to-learn. At a more abstract (nomothetic) level, these differences may be due to emergent divisions of labor (roles) within the two groups. From the perspective of Activity Theory (Leont'ev, 1978; Engestrom, 1987), roles serve as important mediators that simultaneously allow the social unit to accomplish its objectives, while shaping the development of participants. I describe three roles that capture modes of participation for students interacting in the small groups, and that may contribute to what Engestrom (2001) calls subject-producing activity systems: networked contributor, social member, and isolate. This paper also describes tools for teachers and researchers to use in identifying levels of mediation and roles as they occur in small groups.

Active site remodelling accompanies thioester bond formation in the SUMO E1  

SciTech Connect

E1 enzymes activate ubiquitin (Ub) and ubiquitin-like (Ubl) proteins in two steps by carboxy-terminal adenylation and thioester bond formation to a conserved catalytic cysteine in the E1 Cys domain. The structural basis for these intermediates remains unknown. Here we report crystal structures for human SUMO E1 in complex with SUMO adenylate and tetrahedral intermediate analogues at 2.45 and 2.6 {angstrom}, respectively. These structures show that side chain contacts to ATP-Mg are released after adenylation to facilitate a 130 degree rotation of the Cys domain during thioester bond formation that is accompanied by remodelling of key structural elements including the helix that contains the E1 catalytic cysteine, the crossover and re-entry loops, and refolding of two helices that are required for adenylation. These changes displace side chains required for adenylation with side chains required for thioester bond formation. Mutational and biochemical analyses indicate these mechanisms are conserved in other E1s.

Time course of regional brain activity accompanying auditory verbal hallucinations in schizophrenia  

PubMed Central

Background The pathophysiology of auditory verbal hallucinations remains poorly understood. Aims To characterise the time course of regional brain activity leading to auditory verbal hallucinations. Method During functional magnetic resonance imaging, 11 patients with schizophrenia or schizoaffective disorder signalled auditory verbal hallucination events by pressing a button. To control for effects of motor behaviour, regional activity associated with hallucination events was scaled against corresponding activity arising from random button-presses produced by 10 patients who did not experience hallucinations. Results Immediately prior to the hallucinations, motor-adjusted activity in the left inferior frontal gyrus was significantly greater than corresponding activity in the right inferior frontal gyrus. In contrast, motor-adjusted activity in a right posterior temporal region overshadowed corresponding activity in the left homologous temporal region. Robustly elevated motor-adjusted activity in the left temporal region associated with auditory verbal hallucinations was also detected, but only subsequent to hallucination events. At the earliest time shift studied, the correlation between left inferior frontal gyrus and right temporal activity was significantly higher for the hallucination group compared with non-hallucinating patients. Conclusions Findings suggest that heightened functional coupling between the left inferior frontal gyrus and right temporal regions leads to coactivation in these speech processing regions that is hallucinogenic. Delayed left temporal activation may reflect impaired corollary discharge contributing to source misattribution of resulting verbal images.

Systemic ?-adrenergic stimulation of thermogenesis is not accompanied by brown adipose tissue activity in humans.  

PubMed

Brown adipose tissue (BAT) is currently considered as a target to combat obesity and diabetes in humans. BAT is densely innervated by the sympathetic nervous system (SNS) and can be stimulated by ?-adrenergic agonists, at least in animals. However, the exact role of the ?-adrenergic part of the SNS in BAT activation in humans is not known yet. In this study, we measured BAT activity by 2-deoxy-2-[(18)F]fluoro-d-glucose ([(18)F]FDG) positron emission tomography/computed tomography imaging in 10 lean men during systemic infusion of the nonselective ?-agonist isoprenaline (ISO) and compared this with cold-activated BAT activity. ISO successfully mimicked sympathetic stimulation as shown by increased cardiovascular and metabolic activity. Energy expenditure increased to similar levels as during cold exposure. Surprisingly, BAT was not activated during ?-adrenergic stimulation. We next examined whether the high plasma free fatty acid (FFA) levels induced by ISO competed with glucose ([(18)F]FDG) uptake in BAT locations by blocking lipolysis with acipimox (ACI). ACI successfully lowered plasma FFA, but did not increase [(18)F]FDG-uptake in BAT. We therefore conclude that systemic nonselective ?-adrenergic stimulation by ISO at concentrations that increase energy expenditure to the same extent as cold exposure does not activate BAT in humans, indicating that other tissues are responsible for the increased ?-adrenergic thermogenesis.

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.

Activation of Alpha Chymotrypsin by Three Phase Partitioning Is Accompanied by Aggregation  

PubMed Central

Precipitation of alpha chymotrypsin in the simultaneous presence of ammonium sulphate and t-butanol (three phase partitioning) resulted in preparations which showed self aggregation of the enzyme molecules. Precipitation with increasing amounts of ammonium sulphate led to increasing size of aggregates. While light scattering estimated the hydrodynamic diameter of these aggregates in the range of 242–1124 nm; Nanoparticle tracking analysis (NTA) gave the value as 130–462 nm. Scanning electron microscopy and gel filtration on Sephadex G-200 showed extensive aggregation in these preparations. Transmission electron microscopy showed that the aggregates had irregular shapes. All the aggregates had about 3× higher catalytic activity than the native enzyme. These aggregates did not differ in ?max of fluorescence emission which was around 340 nm. However, all the aggregates showed higher fluorescence emission intensity. Far-UV and near-UV circular dichroism also showed no significant structural changes as compared to the native molecule. Interestingly, HPLC gel filtration (on a hydroxylated silica column) gave 14 nm as the diameter for all preparations. Light scattering of preparations in the presence of 10% ethylene glycol also dissociated the aggregates to monomers of 14 nm. Both these results indicated that hydrophobic interactions were the driving force behind this aggregation. These results indicate: (1) Even without any major structural change, three phase partitioning led to protein molecules becoming highly prone to aggregation. (2) Different methods gave widely different estimates of sizes of aggregates. It was however possible to reconcile the data obtained with various approaches. (3) The nature of the gel filtration column is crucial and use of this technique for refolding and studying aggregation needs a rethink.

How Now Brown Cow: Phoneme Awareness Activities for Collaborative Classrooms  

Microsoft Academic Search

Research indicates a strong relationship between early phoneme awareness and later reading success, and it links some reading failure to insufficiently developed phoneme awareness skills. Intervention research clearly demonstrates the benefits of explicitly teaching phoneme awareness skills. Many children at risk for reading failure are in general education classrooms where phoneme awareness training is not part of their reading program.

Transcriptional activation of the lipoprotein lipase and apolipoprotein E genes accompanies differentiation in some human macrophage-like cell lines  

SciTech Connect

Stimulation of the macrophage-like cell line THP-1 with the phorbol ester phorbol 12-myristate 13-acetate (PMA) resulted in differentiation into cells with many features of macrophages. This differentiation was accompanied by transcriptional activation of the lipoprotein lipase (LPL) and apo E genes and accumulation of their protein products in the media. PMA-induced differentiation of the HEL and HL-60 cell lines was not accompanied by induction of the gene for LPL, whereas the apo E gene was induced slightly in HL-60 cells. By contrast, the gene for superoxide dismutase (SOD-1) was either unaffected (THP-1) or down regulated (HL-60 or HEL cells) by PMA treatment. Induction of LPL mRNA in THP-1 cells as dependent upon the concentration of phorbol ester added. A minimal concentration of 1.6 x 10/sup -8/ M PMA was necessary for macrophage differentiation, induction of LPL mRNA, and synthesis of the enzyme. LPL mRNA accumulates within 3 h after stimulation with PMA and attains a maximum concentration after 6 h, thereafter slowly decreasing over the next 3 days. In contrast, the steady-state level of apo E mRNA in the same THP-1 cultures increased gradually over a period of 48 h after induction. These studies thus demonstrate that THP-1 cells are of value as a model to study the quantitative and temporal expression of the LPL and apo E genes during macrophage differentiation.

Acetylation of a Specific Promoter Nucleosome Accompanies Activation of the ?-Globin Gene by ?-Globin Locus Control Region HS2  

PubMed Central

On stably replicating episomes, transcriptional activation of the ?-globin promoter by the ?-globin locus control region HS2 enhancer is correlated with an increase in nuclease sensitivity which is limited to the TATA-proximal nucleosome (N1). To elucidate what underlies this increase in nuclease sensitivity and the link between chromatin modification and gene expression, we examined the nucleoprotein composition and histone acetylation status of transcriptionally active and inactive promoters. Micrococcal nuclease digestion of active promoters in nuclei released few nucleosome-like nucleoprotein complexes containing N1 sequences in comparison to results with inactive promoters. We also observed that N1 DNA fragments from active promoters are of a subnucleosomal length. Nevertheless, chromatin immunoprecipitation experiments indicate that histones H3 and H4 are present on N1 sequences from active promoters, with H3 being dramatically hyperacetylated compared with that from inactive promoters and vector sequences. Strikingly, H3 in the adjacent upstream nucleosome (N2) does not appear to be differentially acetylated in active and inactive promoters, indicating that the nucleosome modification of the promoter that accompanies transactivation by HS2 is highly directed and specific. However, global acetylation of histones in vivo by trichostatin A did not activate transcription in the absence of HS2, suggesting that HS2 contributes additional activities necessary for transactivation. N1 sequences from active promoters also contain reduced levels of linker histone H1. The detection of a protected subnucleosomal sized N1 DNA fragment and the recovery of N1 DNA sequences in immunoprecipitations using anti-acetylated H3 and H4 antibodies argue that N1 is present, but in an altered conformation, in the active promoters.

An Inquiry "Warm-Up" Activity: Preparing Students for an Active Classroom Community  

NASA Astrophysics Data System (ADS)

An active learning community that engages in inquiry activities will employ strategies and structures that students from traditional classrooms may find unfamiliar or uncomfortable. These include group work, voicing questions, shifting from one part of an activity to another (and sometimes shifting groups at the same time), presenting informally to the group, and many others. In addition, the role of the instructor as facilitator rather than teacher may not be familiar to students. As inquiry activities become incorporated into the regular classroom curriculum at Maui Community College (through collaboration with the Professional Development Program as part of the Akamai Workforce Initiative), a need emerged to give students a "warm-up" early in the semester to help them practice these participation structures. This activity was designed to be used on the very first day of class, to be easy and accessible to students, and to give them practice with these features of inquiry activities that they would see again throughout the semester. In addition, the activity introduces the engineering technology concepts of requirements, trade-offs, and limitations. It is important to note that this activity is not in and of itself an inquiry activity; in fact the content and processes featured in the activity are not particularly challenging nor are they the main focus. Instead, this is a "warm-up" for inquiry, so that students gain some comfort with the unconventional features of inquiry activities. The particular activity presented is for 20-30 students in a ˜90 minute lab period, and highlights different imaging technologies of cameras; however, it is easily adaptable to other requirements, to different technology, or other needs.

Hypoxia preconditioning of mesenchymal stromal cells enhances PC3 cell lymphatic metastasis accompanied by VEGFR-3/CCR7 activation.  

PubMed

Mesenchymal stromal cells (MSCs) in bone marrow may enhance tumor metastases through the secretion of chemokines. MSCs have been reported to home toward the hypoxic tumor microenvironment in vivo. In this study, we investigated prostate cancer PC3 cell behavior under the influence of hypoxia preconditioned MSCs and explored the related mechanism of prostate cancer lymphatic metastases in mice. Transwell assays revealed that VEGF-C receptor, VEGFR-3, as well as chemokine CCL21 receptor, CC chemokine receptor 7 (CCR7), were responsible for the migration of PC3 cells toward hypoxia preconditioned MSCs. Knock-in Ccr7 in PC3 cells also improved cell migration in vitro. Furthermore, when PC3 cells were labeled using the hrGfp-lentiviral vector, and were combined with hypoxia preconditioned MSCs for xenografting, it resulted in an enhancement of lymph node metastases accompanied by up-regulation of VEGFR-3 and CCR7 in primary tumors. Both PI3K/Akt/I?B? and JAK2/STAT3 signaling pathways were activated in xenografts in the presence of hypoxia-preconditioned MSCs. Unexpectedly, the p-VEGFR-2/VEGFR-2 ratio was attenuated accompanied by decreased JAK1 expression, indicating a switching-off of potential vascular signal within xenografts in the presence of hypoxia-preconditioned MSCs. Unlike results from other studies, VEGF-C maintained a stable expression in both conditions, which indicated that hypoxia preconditioning of MSCs did not influence VEGF-C secretion. Our results provide the new insights into the functional molecular events and signalings influencing prostate tumor metastases, suggesting a hopeful diagnosis and treatment in new approaches. J.

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.

Changes in Regional Activity Are Accompanied with Changes in Inter-Regional Connectivity during Four Weeks Motor Learning  

PubMed Central

Structural equation modeling (SEM) and fMRI were used to test whether changes in the regional activity are accompanied by changes in the inter-regional connectivity as motor practice progresses. Ten healthy subjects were trained to perform finger movement task daily for 4 weeks. Three sessions of fMRI images were acquired within four weeks. The changes in inter-regional connectivity were evaluated by measuring the effective connectivity between the primary motor area (M1), supplementary motor area (SMA), dorsal premotor cortex (PMd), basal ganglia (BG), cerebellum (CB), and posterior ventrolateral prefrontal cortex (pVLPFC). The regional activities in M1 and SMA increased from pre-training to Week 2 and decreased from Week 2 to Week 4. The inter-regional connectivity generally increased in strength (with SEM path coefficients becoming more positive or negative) as practice progressed. The increases in the strength of the inter-regional connectivity may reflect long-term reorganization of the skilled motor network. We suggest that the performance gain was achieved by dynamically tuning the inter-regional connectivity in the motor network.

Regulatory Activation Is Accompanied by Movement in the C Terminus of the Na-K-Cl Cotransporter (NKCC1)*  

PubMed Central

The Na-K-Cl cotransporter (NKCC1) is expressed in most vertebrate cells and is crucial in the regulation of cell volume and intracellular chloride concentration. To study the structure and function of NKCC1, we tagged the transporter with cyan (CFP) and yellow (YFP) fluorescent proteins at two sites within the C terminus and measured fluorescence resonance energy transfer (FRET) in stably expressing human embryonic kidney cell lines. Both singly and doubly tagged NKCC1s were appropriately produced, trafficked to the plasma membrane, and exhibited 86Rb transport activity. When both fluorescent probes were placed within the same C terminus of an NKCC1 transporter, we recorded an 11% FRET decrease upon activation of the transporter. This result clearly demonstrates movement of the C terminus during the regulatory response to phosphorylation of the N terminus. When we introduced CFP and YFP separately in different NKCC1 constructs and cotransfected these in HEK cells, we observed FRET between dimer pairs, and the fractional FRET decrease upon transporter activation was 46%. Quantitatively, this indicates that the largest FRET-signaled movement is between dimer pairs, an observation supported by further experiments in which the doubly tagged construct was cotransfectionally diluted with untagged NKCC1. Our results demonstrate that regulation of NKCC1 is accompanied by a large movement between two positions in the C termini of a dimeric cotransporter. We suggest that the NKCC1 C terminus is involved in transport regulation and that dimerization may play a key structural role in the regulatory process. It is anticipated that when combined with structural information, our findings will provide a model for understanding the conformational changes that bring about NKCC1 regulation.

Increased site-specific phosphorylation of tyrosine hydroxylase accompanies stimulation of enzymatic activity induced by cessation of dopamine neuronal activity.  

PubMed

Activation of striatal dopamine (DA) neurons by neuroleptic treatment or by electrical stimulation of the nigrostriatal pathway increases the activity of tyrosine hydroxylase (TH). The increase is mediated by phosphorylation of the enzyme. However, abolition of DA neuronal activity [by gamma-butyrolactone (GBL) treatment or transection of the nigrostriatal pathway] also increases TH activity. Quantitative blot immunolabeling experiments using site- and phosphorylation state-specific antibodies to TH demonstrated that GBL treatment (750 mg/kg, 35 min) significantly increased phosphorylation at Ser19 (+40%) and Ser40 (+217%) without altering Ser31 phosphorylation. Concomitantly, GBL treatment [along with the 3,4-dihydroxyphenylalanine (dopa) decarboxylase inhibitor NSD-1015, 100 mg/kg, 30 min] increased in vivo striatal dopa accumulation and in vitro TH activity 3-fold. Likewise, cerebral hemitransection of the nigrostriatal pathway significantly increased phosphorylation of TH at Ser19 (+89%) and Ser40 (+158%) but not at Ser31; dopa levels were increased accordingly (+191%). Kinetic analysis of TH activity established that GBL treatment and hemitransection primarily decreased the Km for the cofactor tetrahydrobiopterin (3-fold). The effects of GBL and hemitransection were abolished or attenuated by pretreatment with the DA agonist R-(-)-N-n-propylnorapomorphine (NPA; 30 microgram/kg, 40 min), presumably via stimulation of inhibitory presynaptic DA autoreceptors. NPA dose-response curves for reversal of GBL-induced dopa accumulation and Ser40 phosphorylation were identical; however, only the highest dose of NPA reversed the small and variable increase in Ser19 phosphorylation. Thus, TH activity seems to be regulated by phosphorylation in both hyper- and hypoactive striatal DA neurons; in the latter case, activation seems to be caused by selective phosphorylation of Ser40.

ATM activation accompanies histone H2AX phosphorylation in A549 cells upon exposure to tobacco smoke  

PubMed Central

Background In response to DNA damage or structural alterations of chromatin, histone H2AX may be phosphorylated on Ser139 by phosphoinositide 3-kinase related protein kinases (PIKKs) such as ataxia telangiectasia mutated (ATM), ATM-and Rad-3 related (ATR) kinase, or by DNA dependent protein kinase (DNA-PKcs). When DNA damage primarily involves formation of DNA double-strand breaks (DSBs), H2AX is preferentially phosphorylated by ATM rather than by the other PIKKs. We have recently reported that brief exposure of human pulmonary adenocarcinoma A549 cells or normal human bronchial epithelial cells (NHBE) to cigarette smoke (CS) induced phosphorylation of H2AX. Results We report here that H2AX phosphorylation in A549 cells induced by CS was accompanied by activation of ATM, as revealed by ATM phosphorylation on Ser1981 (ATM-S1981P) detected immunocytochemically and by Western blotting. No cell cycle-phase specific differences in kinetics of ATM activation and H2AX phosphorylation were observed. When cells were exposed to CS from cigarettes with different tobacco and filter combinations, the expression levels of ATM-S1981P correlated well with the increase in expression of phosphorylated H2AX (?H2AX) (R = 0.89). In addition, we note that while CS-induced ?H2AX expression was localized within discrete foci, the activated ATM was distributed throughout the nucleoplasm. Conclusion These data implicate ATM as the PIKK that phosphorylates H2AX in response to DNA damage caused by CS. Based on current understanding of ATM activation, expression and localization, these data would suggest that, in addition to inducing potentially carcinogenic DSB lesions, CS may also trigger other types of DNA lesions and cause chromatin alterations. As checkpoint kinase (Chk) 1, Chk2 and the p53 tumor suppressor gene are known to be phosphorylated by ATM, the present data indicate that exposure to CS may lead to their phosphorylation, with the downstream consequences related to the halt in cell cycle progression and increased propensity to undergo apoptosis. Defining the nature and temporal sequence of molecular events that are disrupted by CS through activation and eventual dysregulation of normal defense mechanisms such as ATM and its downstream effectors may allow a more precise understanding of how CS promotes cancer development.

Vodcasts and Active-Learning Exercises in a "Flipped Classroom" Model of a Renal Pharmacotherapy Module  

PubMed Central

Objective. To implement a “flipped classroom” model for a renal pharmacotherapy topic module and assess the impact on pharmacy students’ performance and attitudes. Design. Students viewed vodcasts (video podcasts) of lectures prior to the scheduled class and then discussed interactive cases of patients with end-stage renal disease in class. A process-oriented guided inquiry learning (POGIL) activity was developed and implemented that complemented, summarized, and allowed for application of the material contained in the previously viewed lectures. Assessment. Students’ performance on the final examination significantly improved compared to performance of students the previous year who completed the same module in a traditional classroom setting. Students’ opinions of the POGIL activity and the flipped classroom instructional model were mostly positive. Conclusion. Implementing a flipped classroom model to teach a renal pharmacotherapy module resulted in improved student performance and favorable student perceptions about the instructional approach. Some of the factors that may have contributed to students’ improved scores included: student mediated contact with the course material prior to classes, benchmark and formative assessments administered during the module, and the interactive class activities.

Insulin-stimulated expression of c-fos, fra1 and c-jun accompanies the activation of the activator protein-1 (AP-1) transcriptional complex.  

PubMed Central

The activator protein-1 (AP-1) transcriptional complex is made up of members of the Fos (c-Fos, FosB, Fra1, Fra2) and Jun (c-Jun, JunB, JunD) families and is stimulated by insulin in several cell types. The mechanism by which insulin activates this complex is not well understood but it is dependent on the activation of the Erk1 and Erk2 isoforms of mitogen-activated protein kinases. In the current study we show that the AP-1 complex isolated from insulin-stimulated cells contained c-Fos, Fra1, c-Jun and JunB. The activation of the AP-1 complex by insulin was accompanied by (i) a transient increase in c-fos expression, and the transactivation of the ternary complex factors Elk1 and Sap1a, in an Erk1/Erk2-dependent fashion; (ii) a substantial increase in the expression of Fra1 protein and mRNA, which was preceded by a transient decrease in its electrophoretic mobility upon SDS/PAGE, indicative of phosphorylation; and (iii) a sustained increase in c-jun expression without increasing c-Jun phosphorylation on serines 63 and 73 or activation of the stress-activated kinase JNK/SAPK. In conclusion, insulin appears to stimulate the activity of the AP-1 complex primarily through a change in the abundance of the components of this complex, although there may be an additional role for Fra1 phosphorylation.

Teachers' scientific knowledge, teaching practice, and students' learning activities: Cases of three elementary classroom teachers  

NASA Astrophysics Data System (ADS)

The purposes of this dissertation study are to better understand what specific types of scientific knowledge and practice three elementary teachers exhibit, and to examine how they use their scientific knowledge in their classroom teaching practice to provide students' opportunities to learn science when teaching condensation in the context of a unit on the water cycle. By comparing and contrasting three cases of elementary classroom teaching, this study discusses what kinds of scientific knowledge and practice are fundamental for teaching elementary science for scientific understanding. The data include structured interviews (content, pre- and post- observation, and stimulated recall), videotaped classroom observations, and collections of teachers' and students' written artifacts. Data were collected prior to, during, and after the three teachers taught condensation to fifth grade students. The data were analyzed in three contexts: interviews, teaching practices, and students' classroom activities. This made it possible to clarify which characteristics of teacher's scientific knowledge influenced which aspects of their teaching practice. Data analysis shows that teachers' scientific knowledge were closely associated with their teaching practice and students' classroom activities. Two characteristics of the teachers' scientific reasoning emerged as especially important. The first concerned how teachers connected observations of condensation with patterns in those observations (e.g., condensation occurs when warm moist air cools) and with explanations for those patterns (e.g., condensation is water vapor that changes to liquid water). Two teachers were careful to connect observations with patterns in their own thinking and in their classroom teaching. One of those teachers also connected the observations and patterns to scientific explanations. In contrast, the third teacher focused on listing scientific terms with little elaboration with specific observations and patterns. The second important characteristic of teachers' scientific reasoning concerned their views of science. One teacher enacted a largely inductive, empirical view, helping her students to observe examples of condensation, to find patterns in their observations, and to label the patterns as condensation. The second teacher engaged the students in a detailed series of experiments and data-based arguments designed to demonstrate that the liquid water in condensation was originally water vapor in the air. The third teacher focused on teaching students facts and vocabulary from authoritative sources, including their textbook and dictionaries. This study discusses what it means to have a deep understanding of fundamental science for elementary teachers. Making connections among observations, patterns, and explanations is important for students to understand the scientific world. Scientific practices, inquiry and application, play an important role to help teachers and students connect observations, patterns, and explanations. The implications to elementary science teacher education are discussed, considering how we can prepare elementary teachers to use scientific knowledge in their teaching practice.

Creating Classroom Activities About Ocean Drilling Geophysics Through Scientist-Teacher Collaboration  

NASA Astrophysics Data System (ADS)

How can examples of geophysical data used in research be effectively taught to middle and high school students with only general science knowledge? Logging data, or logs, are continuous measurements of physical properties made in situ and at high resolution by lowering instruments into boreholes after completion of coring. As part of the Integrated Ocean Drilling Program (IODP) "School of Rock 2007" (http://www.joilearning.org/schoolofrock2007), we created a classroom activity to introduce pre-college students to representative logging data collected by the R/V JOIDES Resolution during expeditions of the Ocean Drilling Program (ODP) and the Integrated Ocean Drilling Program (IODP). The synergistic model for curriculum development involving a research scientist (Guerin) and classroom teacher (Passow) provides an efficient strategy to disseminate technical research methods and results more widely with students and teachers. The "School of Rock 2007" brought 18 educators and 12 scientists together at the Texas A and M IODP Gulf Coast Observatory for a week in July to learn about techniques in sea floor exploration and advances in understanding the Earth's climate using geophysics, biostratigraphy, geomagnetics, and more. Teachers and researchers then collaborated to produce classroom activities that will add to the existing collection of educational resources available through JOI Learning (http://www.joiscience.org/learning). The activity we developed introduces students to general concepts of downhole logging, then presents sample data from three sites. Using guiding information provided, students engage in simplified interpretation of the data to identify such features as sedimentary layers, igneous rocks, or gas hydrate-bearing formations. Activities include questions about geography, identifying patterns within the data, recognizing distinctive features in gamma ray, resistivity, density and porosity logs. The curriculum materials will be tested with students and teachers in various setting during Fall 2007, including as part of the Earth2Class Workshops for Teachers (http://www.earth2class.org) and the Lamont-Doherty Earth Observatory Open House (http://www.ldeo.columbia.edu.)

Promoting active learning in large classes using a classroom communication system  

NASA Astrophysics Data System (ADS)

We provide an overview of an instructional strategy aimed at promoting active learning in introductory physics courses. Although a classroom communication system called Classtalk was used to facilitate the interactions among students, and between the students and the instructor, the use of Classtalk is not essential for implementing the instructional strategies described herein. A major focus of this article is a discussion of the types of questions that we have found work well in generating group, and class-wide discussions of physics concepts. We also discuss the types of reasoning used by students to answer specific conceptual questions.

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.

The ?-carboline alkaloid harmine inhibits telomerase activity of MCF-7 cells by down-regulating hTERT mRNA expression accompanied by an accelerated senescent phenotype.  

PubMed

The end replication problem, which occurs in normal somatic cells inducing replicative senescence, is solved in most cancer cells by activating telomerase. The activity of telomerase is highly associated with carcinogenesis which makes the enzyme an attractive biomarker in cancer diagnosis and treatment. The indole alkaloid harmine has multiple pharmacological properties including DNA intercalation which can lead to frame shift mutations. In this study, harmine was applied to human breast cancer MCF-7 cells. Its activity towards telomerase was analyzed by utilizing the telomeric repeat amplification protocol (TRAP). Our data indicate that harmine exhibits a pronounced cytotoxicity and induces an anti-proliferation state in MCF-7 cells which is accompanied by a significant inhibition of telomerase activity and an induction of an accelerated senescence phenotype by over-expressing elements of the p53/p21 pathway.

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.

Down-regulation of Fer induces ROS levels accompanied by ATM and p53 activation in colon carcinoma cells.  

PubMed

Fer is an intracellular tyrosine kinase which resides in both the cytoplasm and nucleus of mammalian cells. This kinase was also found in all malignant cell-lines analyzed and was shown to support cell-cycle progression in cancer cells. Herein we show that knock-down of Fer, both, impairs cell-cycle progression and imposes programmed cell death in colon carcinoma (CC) cells. The cell-cycle arrest and apoptotic death invoked by the depletion of Fer were found to depend on the activity of p53. Accordingly, down regulation of Fer led to the activation of the Ataxia Telangiectasia Mutated protein (ATM) and its down-stream effector-p53. Knock-down of Fer also increased the level of Reactive-Oxygen Species (ROS) in CC cells, and subjection of Fer depleted cells to ROS neutralizing scavengers significantly decreased the induced phosphorylation and activation of ATM and p53. Notably, over-expression of Fer opposed the Doxorubicin driven activation of ATM and p53, which can be mediated by ROS. Collectively, our findings imply that Fer sustains low ROS levels in CC cells, thereby restraining the activation of ATM and p53 in these cells. PMID:22434045

An Increase in Pectin Methyl Esterase Activity Accompanies Dormancy Breakage and Germination of Yellow Cedar Seeds1  

PubMed Central

Pectin methyl esterase (PME) (EC 3.1.1.11) catalyzes the hydrolysis of methylester groups of cell wall pectins. We investigated the role of this enzyme in dormancy termination and germination of yellow cedar (Chamaecyparis nootkatensis [D. Don] Spach) seeds. PME activity was not detected in dormant seeds of yellow cedar but was induced and gradually increased during moist chilling; high activity coincided with dormancy breakage and germination. PME activity was positively correlated to the degree of dormancy breakage of yellow cedar seeds. The enzyme produced in different seed parts and in seeds at different times during moist chilling, germination, and early post-germinative growth consisted of two isoforms, both basic with isoelectric points of 8.7 and 8.9 and the same molecular mass of 62 kD. The pH optimum for the enzyme was between 7.4 and 8.4. In intact yellow cedar seeds, activities of the two basic isoforms of PME that were induced in embryos and in megagametophytes following dormancy breakage were significantly suppressed by abscisic acid. Gibberellic acid had a stimulatory effect on the activities of these isoforms in embryos and megagametophytes of intact seeds at the germinative stage. We hypothesize that PME plays a role in weakening of the megagametophyte, allowing radicle emergence and the completion of germination.

Increased large conductance calcium-activated potassium (BK) channel expression accompanied by STREX variant downregulation in the developing mouse CNS  

Microsoft Academic Search

BACKGROUND: Large conductance calcium- and voltage activated potassium (BK) channels are important determinants of neuronal excitability through effects on action potential duration, frequency and synaptic efficacy. The pore- forming subunits are encoded by a single gene, KCNMA1, which undergoes extensive alternative pre mRNA splicing. Different splice variants can confer distinct properties on BK channels. For example, insertion of the 58

Sulfoxide stimulation of chondrogenesis in limb mesenchyme is accompanied by an increase in type II collagen enhancer activity  

SciTech Connect

We have utilized a modification of the limb bud mesenchyme micromass culture system to screen compounds that might stimulate chondrogenesis. Two compounds in the sulfoxide family (methylphenylsulfoxide and p-chlorophenyl methyl sulfoxide) were stimulatory at 10(-2) M and 10(-3) M, respectively; whereas other sulfoxides and organic solvents were not active at these concentrations. In addition, specific growth factors (basic FGF, IGF-I, IGF-II) were not chondroinductive at concentrations that are active in other cell systems. Both sulfoxide compounds stimulated cartilage nodule formation, ({sup 35}S)sulfate incorporation, and activity of the regulatory sequences of the collagen II gene. In contrast, transforming growth factor beta-1 (10 ng/ml) stimulated sulfate incorporation but produced only a diffuse deposition of cartilage matrix and reduced the ability of the cells to utilize the regulatory sequences of the collagen II gene. The sulfoxides appear to promote the differentiation of limb bud cells to chondrocytes and thus exhibit chondroinductive activity.

Nerve Growth Factor-Induced Differentiation of PC12 Cells Is Accompanied by Elevated Adenylyl Cyclase Activity  

Microsoft Academic Search

Rat pheochromocytoma (PC12) cells characteristically undergo differentiation when cultured with nerve growth factor (NGF). Here we show that NGF dramatically increased the adenylyl cyclase-activating property of forskolin in PC12 cells. This effect of NGF was well maintained even when NGF was removed after 4 days, even though the morphological features of neuronal differentiation were rapidly lost on removal of NGF.

Transpositional activation of mPing in an asymmetric nuclear somatic cell hybrid of rice and Zizania latifolia was accompanied by massive element loss.  

PubMed

We have reported previously that the most active miniature inverted terminal repeat transposable element (MITE) of rice, mPing, was transpositionally mobilized in several rice recombinant inbred lines (RILs) derived from an introgressive hybridization between rice and wild rice (Zizania latifolia Griseb.). To further study the phenomenon of hybridization-induced mPing activity, we undertook the present study to investigate the element's behavior in a highly asymmetric somatic nuclear hybrid (SH6) of rice and Z. latifolia, which is similar in genomic composition to that of the RILs, though probably contains more introgressed alien chromatins from the donor species than the RILs. We found that mPing, together with its transposase-donor, Pong, underwent rampant transpositional activation in the somatic hybrid (SH6). Because possible effects of protoplast isolation and cell culture can be ruled out, we attribute the transpositional activation of mPing and Pong in SH6 to the process of asymmetric somatic hybridization, namely, one-step introgression of multiple chromatin segments of the donor species Z. latifolia into the recipient rice genome. A salient feature of mPing transposition in the somatic hybrid is that the element's activation was accompanied by massive loss of its original copies, i.e., abortive transpositions, which was not observed in previously reported cases of mPing activity. These data not only corroborated our earlier finding that wide hybridization and introgression may trigger transpositional activation of otherwise quiescent transposable elements, but also suggest that transpositional mobilization of a MITE like mPing can be accompanied by dramatic reduction of its original copy numbers under certain conditions, thus provide novel insights into the dynamics of MITEs in the course of genome evolution.

Functional balance of the hemagglutinin and neuraminidase activities accompanies the emergence of the 2009 H1N1 influenza pandemic.  

PubMed

The 2009 H1N1 influenza pandemic is the first human pandemic in decades and was of swine origin. Although swine are believed to be an intermediate host in the emergence of new human influenza viruses, there is still little known about the host barriers that keep swine influenza viruses from entering the human population. We surveyed swine progenitors and human viruses from the 2009 pandemic and measured the activities of the hemagglutinin (HA) and neuraminidase (NA), which are the two viral surface proteins that interact with host glycan receptors. A functional balance of these two activities (HA binding and NA cleavage) is found in human viruses but not in the swine progenitors. The human 2009 H1N1 pandemic virus exhibited both low HA avidity for glycan receptors as a result of mutations near the receptor binding site and weak NA enzymatic activity. Thus, a functional match between the hemagglutinin and neuraminidase appears to be necessary for efficient transmission between humans and may be an indicator of the pandemic potential of zoonotic viruses.

Proteolytic Activation of the Essential Parasitophorous Vacuole Cysteine Protease SERA6 Accompanies Malaria Parasite Egress from Its Host Erythrocyte*  

PubMed Central

The malaria parasite replicates within an intraerythrocytic parasitophorous vacuole (PV). The PV and host cell membranes eventually rupture, releasing merozoites in a process called egress. Certain inhibitors of serine and cysteine proteases block egress, indicating a crucial role for proteases. The Plasmodium falciparum genome encodes nine serine-repeat antigens (SERAs), each of which contains a central domain homologous to the papain-like (clan CA, family C1) protease family. SERA5 and SERA6 are indispensable in blood-stage parasites, but the function of neither is known. Here we show that SERA6 localizes to the PV where it is precisely cleaved just prior to egress by an essential serine protease called PfSUB1. Mutations that replace the predicted catalytic Cys of SERA6, or that block SERA6 processing by PfSUB1, could not be stably introduced into the parasite genomic sera6 locus, indicating that SERA6 is an essential enzyme and that processing is important for its function. We demonstrate that cleavage of SERA6 by PfSUB1 converts it to an active cysteine protease. Our observations reveal a proteolytic activation step in the malarial PV that may be required for release of the parasite from its host erythrocyte.

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.

Mitotic Defects Lead to Pervasive Aneuploidy and Accompany Loss of RB1 Activity in Mouse LmnaDhe Dermal Fibroblasts  

PubMed Central

Background Lamin A (LMNA) is a component of the nuclear lamina and is mutated in several human diseases, including Emery-Dreifuss muscular dystrophy (EDMD; OMIM ID# 181350) and the premature aging syndrome Hutchinson-Gilford progeria syndrome (HGPS; OMIM ID# 176670). Cells from progeria patients exhibit cell cycle defects in both interphase and mitosis. Mouse models with loss of LMNA function have reduced Retinoblastoma protein (RB1) activity, leading to aberrant cell cycle control in interphase, but how mitosis is affected by LMNA is not well understood. Results We examined the cell cycle and structural phenotypes of cells from mice with the Lmna allele, Disheveled hair and ears (LmnaDhe). We found that dermal fibroblasts from heterozygous LmnaDhe (LmnaDhe/+) mice exhibit many phenotypes of human laminopathy cells. These include severe perturbations to the nuclear shape and lamina, increased DNA damage, and slow growth rates due to mitotic delay. Interestingly, LmnaDhe/+ fibroblasts also had reduced levels of hypophosphorylated RB1 and the non-SMC condensin II-subunit D3 (NCAP-D3), a mitosis specific centromere condensin subunit that depends on RB1 activity. Mitotic check point control by mitotic arrest deficient-like 1 (MAD2L1) also was perturbed in LmnaDhe/+ cells. LmnaDhe/+ fibroblasts were consistently aneuploid and had higher levels of micronuclei and anaphase bridges than normal fibroblasts, consistent with chromosome segregation defects. Conclusions These data indicate that RB1 may be a key regulator of cellular phenotype in laminopathy-related cells, and suggest that the effects of LMNA on RB1 include both interphase and mitotic cell cycle control.

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.

SWI/SNF-INDEPENDENT NUCLEASE HYPERSENSITIVITY AND INCREASED HISTONE ACETYLATION AT THE P1 PROMOTER ACCOMPANY ACTIVE TRANSCRIPTION OF THE BONE MASTER GENE RUNX2  

PubMed Central

The Runx2 transcription factor is essential for skeletal development as it regulates expression of several key bone-related genes. Multiple lines of evidence indicate that expression of the Runx2/p57 isoform in osteoblasts is controlled by the distal P1 promoter. Alterations of chromatin structure are often associated with transcription and can be mediated by members of the SWI/SNF family of chromatin remodeling complexes, or by transcriptional co-activators that possess enzymatic activities that covalently modify structural components of the chromatin. Here, we report that a specific chromatin remodeling process at the proximal region (?400 to +35) of the Runx2 gene P1 promoter accompanies transcriptional activity in osteoblasts. This altered chromatin organization is reflected by the presence of two DNase I hypersensitive sites that span key regulatory elements for Runx2/p57 transcription. Chromatin remodeling and transcription of the Runx2 gene are associated with elevated levels of histone acetylation at the P1 promoter region and binding of active RNA polymerase II, and are independent of the activity of the SWI/SNF chromatin remodeling complex. Changes in chromatin organization at the P1 promoter are stimulated during differentiation of C2C12 mesenchymal cells to the osteoblastic lineage by treatment with BMP2. Together, our results support a model in which changes in chromatin organization occur at very early stages of mesenchymal differentiation to facilitate subsequent expression of the Runx2/p57 isoform in osteoblastic cells.

Regular voluntary exercise cures stress-induced impairment of cognitive function and cell proliferation accompanied by increases in cerebral IGF-1 and GST activity in mice.  

PubMed

Chronic stress impairs cognitive function and hippocampal neurogenesis. This impairment is attributed to increases in oxidative stress, which result in the accumulation of lipid peroxide. On the other hand, voluntary exercise enhances cognitive function, hippocampal neurogenesis, and antioxidant capacity in normal animals. However, the effects of voluntary exercise on cognitive function, neurogenesis, and antioxidants in stressed mice are unclear. This study was designed to investigate whether voluntary exercise cures stress-induced impairment of cognitive function accompanied by improvement of hippocampal neurogenesis and increases in antioxidant capacity. Stressed mice were exposed to chronic restraint stress (CRS), which consisted of 12h immobilization daily and feeding in a small cage, for 8 weeks. Exercised mice were allowed free access to a running wheel during their exposure to CRS. At the 6th week, cognitive function was examined using the Morris water maze (MWM) test. Daily voluntary exercise restored stress-induced impairment of cognitive function and the hippocampal cell proliferation of newborn cells but not cell survival. Voluntary exercise increased insulin-like growth factor 1 (IGF-1) protein and mRNA expression in the cerebral cortex and liver, respectively. In addition, CRS resulted in a significant increase in the number of 4-hydrosynonenal (4-HNE)-positive cells in the hippocampal dentate gyrus; whereas, voluntary exercise inhibited it and enhanced glutathione s-transferases (GST) activity in the brain. These findings suggest that voluntary exercise attenuated the stress-induced impairment of cognitive function accompanied by improvement of cell proliferation in the dentate gyrus. This exercise-induced improvement was attributed to exercise-induced enhancement of IGF-1 protein and GST activity in the brain. PMID:20307585

Abnormal Activation of Microglia Accompanied with Disrupted CX3CR1/CX3CL1 Pathway in the Brains of the Hamsters Infected with Scrapie Agent 263K.  

PubMed

Microglial cells are resident mononuclear phagocytes of the central nervous system (CNS). Active proliferation of microglia in the brain has been identified in neurodegenerative disorders, including some kinds of prion disease. However, the detailed regional distribution between microglia and PrP(Sc) deposition has not been presented, and investigation of fractalkine signaling which is involved in the regulation of activation of microglia in prion disease is not well documented. In this study, the disease phenomenon of microglial accumulation in the CNS was thoroughly analyzed using a scrapie-infected experimental model. Western blots of microglia-specific markers Iba1 and CD68, immunohistochemical and immunofluorescent assays demonstrated obviously activation of microglia in almost whole brain regions in the infected animals. Under the dynamic analysis on hallmarks of activation of microglia, a time-dependent increase of Iba1 and CD68 was detected, accompanied by accumulation of PrP(Sc) and progression of neurodegenerative symptoms. With serial brain sections and double staining of Iba1 and PrP(Sc), we observed that the microglia distributed around PrP(Sc) deposits in 263K-infected hamsters' brains, proposing PrP(Sc) phagocytosis. Flow cytometry assays with the single-cell suspensions prepared from the cortical region of the infected brains verified an activation of microglial population. ELISA assays of the cytokines in brain homogenates revealed significant upregulations of interleukin (IL)-1?, IL-6 and TNF-? when infected. Evaluation of fractalkine signaling in the infected hamsters' brains showed progressively downregulation of CX3CL1 during the incubation. Prion peptide PrP106-126 also disrupted fractalkine and evoked microglial activation in rat primary neuron-glia mixed cultures. Our data here demonstrate an activated status of microglia in CNS tissues of infectious prion disease, possibly through fractalkine signaling deficiency. PMID:23526370

T Cell Activation and Proinflammatory Cytokine Production in Clinically Cured Tuberculosis Are Time-Dependent and Accompanied by Upregulation of IL-10  

PubMed Central

Background Th1 cytokines are essential for the control of M. tuberculosis infection. The role of IL-10 in tuberculosis is controversial and there is an increasing body of evidence suggesting that the relationship between Th1 cytokines and IL-10 is not as antagonistic as it was first believed, and that these cytokines may complement each other in infectious diseases. Methods The present study evaluated the activating capacity of CD4+ and CD8+ T cell repertoire in response to antigen stimulation through the expression of CD69 using Flow Cytometry, as well as the functionality of PBMCs by determining the cytokine profile in patients with active tuberculosis and in clinically cured patients after in vitro stimulation using ELISA. Treated patients were subdivided according to time after clinical cure (<12 months or >12 months post-treatment). Results We observed that T cell activation was higher in TB-treated patients, especially CD8+ T cell activation in TB-Treated >1 year. Th1 cytokines were significantly higher in TB-Treated, and the levels of IFN-? and TNF-? increased continuously after clinical cure. Moreover, IL-10 production was significantly higher in cured patients and it was also enhanced in cured patients over time after treatment. Th17, Th2 and Th22 cytokines showed no statistically significant differences between Healthy Donors, Active-TB and TB-Treated. Conclusions This study describes a scenario in which potentiation of CD4+ and CD8+ T cell activation and increased Th1 cytokine production are associated with the clinical cure of tuberculosis in the absence of significant changes in Th2 cytokine production and is accompanied by increased production of IL-10. In contrast to other infections with intracellular microorganisms, this response occurs later after the end of treatment.

Rapid and reversible changes in nucleosome structure accompany the activation, repression, and superinduction of murine fibroblast protooncogenes c-fos and c-myc.  

PubMed Central

A procedure for the isolation of transcriptionally active nucleosomes was used to monitor changes in chromatin structure during the activation, repression, and superinduction of the protooncogenes c-fos and c-myc. Nuclei were isolated from murine fibroblasts at successive times after stimulation of quiescent cell cultures with serum or platelet-derived growth factor. The nucleosomes released by a brief micrococcal nuclease digestion were fractionated by HgII-affinity chromatography to separate the unfolded nucleosomes of transcriptionally active genes (in which the sulfhydryl groups of histone H3 are accessible for binding to HgII) from the compactly beaded nucleosomes of transcriptionally inert DNA sequences (in which the H3 sulfhydryl groups are not accessible). The DNA sequence contents of the HgII-bound and unbound nucleosome fractions were compared by slot-blot hybridizations to 32P-labeled cloned probes for c-fos and c-myc. The binding of the c-fos and c-myc nucleosomes to the HgII column accurately reflected both the timing and the degree of their expression, as determined by run-off transcription assays with the isolated nuclei. The superinduction of c-fos and c-myc expression by an inhibitor of protein synthesis (cycloheximide) was reflected in the persistence of the unfolded, transcriptionally active state of their component nucleosomes. These results provide direct evidence that rapid and reversible changes in nucleosome topography accompany the program of oncogene expression, and they suggest a way to monitor aberrant gene activity during malignant transformation.

Examples are presented for the two-, three-, and four-cluster accompanied cold fission of {sup 252}Cf and {sup 262}Rf, in which the emitted clusters are 2{alpha}, {alpha}+{sup 6}He, {alpha}+{sup 10}Be, {alpha}+{sup 14}C, 3{alpha}, {alpha}+{sup 6}He+{sup 10}Be, 2{alpha}+{sup 6}He, 2{alpha}+{sup 8}Be, 2{alpha}+{sup 14}C, and 4{alpha}. A comparison is made with the recently observed {sup 252}Cf cold binary fission, and cold ternary (accompanied by {alpha} particle or by {sup 10}Be cluster). The strong shell effect corresponding to the doubly magic heavy fragment {sup 132}Sn is emphasized. The most favorable mechanism of such a decay mode should be the emission from an elongated neck formed between the two heavy fragments. {copyright} {ital 1999} {ital The American Physical Society}

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.

Additional repression of activity-dependent c-fos and BDNF mRNA expression by lipophilic compounds accompanying a decrease in Ca2+ influx into neurons.  

PubMed

Recently, it has been proposed that a variety of environmental disruptors (EDs) disturb the neonatal development of the brain in mammals because of their lipophilic characteristics. Therefore, the synergism of these lipophilic compounds is important when evaluating the risk from EDs. In mouse cerebellar granule cells (CGCs), the activity-dependent expression of the brain-derived neurotrophic factor (BDNF) gene is activated through an influx of calcium ions (Ca2+) into CGCs caused by membrane depolarization, which is involved in the activity-dependent development of not only the cerebellum but also other regions of the brain after birth. In our previous study, we reported that permethrin and some other pyrethroid insecticides, which are suspected of being EDs, repressed the induction of c-fos and BDNF mRNA expression, accompanying a reduction of Ca2+ influx at doses non-toxic to CGCs. In the present study, we investigated whether other lipophilic compounds influenced the Ca2+ signal-induced expression of both genes as permethrin did and, if so, whether these effects were synergistic or additional. Pretreatment with p,p'-DDT, diethylstilbestrol (DES) or bisphenol A dose-dependently repressed the induction of both genes as well as the increase in the uptake of Ca2+ by CGCs. Simultaneous exposure of CGCs with permethrin, p,p'-DDT and DES, in addition, revealed an additional repression on the induction of the genes and the Ca2+ uptake. These results suggest that toxic effects of EDs might, at least additionally, occur in the brain even if the concentration of each compound is lower than the effective dose for humans. PMID:15527870

Modification of surfactant protein D by reactive oxygen-nitrogen intermediates is accompanied by loss of aggregating activity, in vitro and in vivo  

PubMed Central

Surfactant protein D (SP-D) is an important effector of innate immunity. We have previously shown that SP-D accumulates at sites of acute bacterial infection and neutrophil infiltration, a setting associated with the release of reactive species such as peroxynitrite. Incubation of native SP-D or trimeric SP-D lectin domains (NCRDs) with peroxynitrite resulted in nitration and nondisulfide cross-linking. Modifications were blocked by peroxynitrite scavengers or pH inactivation of peroxynitrite, and mass spectroscopy confirmed nitration of conserved tyrosine residues within the C-terminal neck and lectin domains. Mutant NCRDs lacking one or more of the tyrosines allowed us to demonstrate preferential nitration of Tyr314 and the formation of Tyr228-dependent cross-links. Although there was no effect of peroxynitrite or tyrosine mutations on lectin activity, incubation of SP-D dodecamers or murine lavage with peroxynitrite decreased the SP-D-dependent aggregation of lipopolysaccharide-coated beads, supporting our hypothesis that defective aggregation results from abnormal cross-linking. We also observed nitration, cross-linking of SP-D, and a significant decrease in SP-D-dependent aggregating activity in the lavage of mice acutely exposed to nitrogen dioxide. Thus, modification of SP-D by reactive oxygen-nitrogen species could contribute to alterations in the structure and function of SP-D at sites of inflammation in vivo.—Matalon, S., Shrestha, K., Kirk, M., Waldheuser, S., McDonald, B., Smith, K., Gao, Z., Belaaouaj, A., Crouch, E. C. Modification of surfactant protein D by reactive oxygen-nitrogen intermediates is accompanied by loss of aggregating activity, in vitro and in vivo.

Effects of sensory education based on classroom activities for lower grade school children  

PubMed Central

This study is to verify the effects of sensory education based on classroom activities for 2nd and 3rd grade children. The hypothesis is that children who participated in sensory education would demonstrate positive changes in eating behaviors through sensory experiences. The sensory education program consists of 12 lessons. Twenty-six children were being recruited from one school in Changwon, Korea. Two control groups, one of which was the same age as the educated group and the other group of sixth graders, were selected by random sampling from the same school. Children answered a self-administered questionnaire. The parents (n = 20) of the children who participated in the program, took part in evaluating the program through self-administered questionnaires after the program ended. The questionnaire contained variables of general characteristics, education satisfaction, nutrition knowledge, eating attitude and behavior concerning unfamiliar foods. The score of nutrition knowledge was improved in educated children (P < 0.05). Food neophobia score towards unfamiliar foods (P < 0.05) was increased in educated children, but there are no changes in eating behaviors in all groups towards unfamiliar foods. In conclusion, sensory education is useful for having a positive eating attitude among children. Its consistent implementation could lead to healthier and well-balanced eating behaviors for children.

Purpose To determine if an existing ballroom dance classroom program meets national recommendations to engage children in moderate to vigorous physical activity (MVPA) for > 50% of class time and to determine class effects on body mass index (BMI). Design Prospective descriptive study. Setting Two New York City public schools. Subjects Seventy-nine fourth and fifth grade students. Measurements The System for Observing Fitness Instruction Time (SOFIT) and direct heart rate monitoring were used to determine subjects’ MVPA levels during class time. Weight and height were measured to calculate BMI. Analysis Means were calculated for continuous variables; frequency counts and percentages were calculated for categorical variables. Change in BMI percentiles was assessed using Bhapkar’s chi-square test of overall marginal homogeneity. Results Data from SOFIT observations showed that a mean of 50.0% and 67.0% of class time in the first and second halves of the program were spent in MVPA. Data from the heart rate monitoring data revealed that 71.1% of students were at ?25% heart rate reserve, indicating MVPA, for ?50% of class time. Improvement was seen in BMI percentile (P=0.051). Conclusion Ballroom dance provides MVPA in elementary school children for ?50 % of class time and has a positive impact on BMI percentiles.

Increasing active student participation in the classroom through the use of ``flash cards''  

NASA Astrophysics Data System (ADS)

Large lecture classes make it difficult to maintain high levels of student-faculty interaction; in these classes, students traditionally play a relatively passive role. We have been making use of techniques for increasing active student participation in the lecture classroom, and for raising the level of interaction between students and instructors. A central element in these methods is the use of ``flash cards'' which allow students to instantaneously indicate to the instructor their responses to multiple-choice questions. Students use 8.5×11 inch flash cards, labeled ``A,'' ``B,'' ``C,'' ``D,'' ``E,'' and ``F'' to signal their responses to the instructor. Flash-card questions emphasize qualitative and proportional reasoning, solution strategies for problems, order of magnitude estimates, etc. Responses provide feedback to the instructor on student misconceptions, and pace of student understanding. Here we show an example of how we break down a conventional problem into conceptual elements-a so-called ``problem dissection''-which can then be formed into flash-card questions.

There is no direct verification of pineal gland involvement in human uveitis. Specimens of pineal tissue are not available during active uveitis in human patients. Naturally occurring uveitis in horses gives us an opportunity to examine tissues during active ocular inflammation. We examined the pineal gland of a horse that was killed because it had become blind during an episode of uveitis. The clinical history and histopathology of the eyes were consistent with post-leptospiral equine recurrent uveitis. The pineal gland of this horse had significant inflammatory infiltration consisting mainly of lymphocytes with some eosinophils. This observation of pinealitis accompanying equine uveitis supports the animal models of experimental autoimmune uveoretinitis with associated pinealitis and suggests that the pineal gland may be involved in some human uveitides.

Bizzy Break! The effect of a classroom-based activity break on in-school physical activity levels of primary school children.  

PubMed

The school has been identified as a key setting to promote physical activity. The purpose of this study was to evaluate the effect of a classroom-based activity break on in-school step counts of primary school children. Data for 90 children (49 boys, 41 girls, 9.3 ± 1.4 years) from three Irish primary schools is presented. In each school one class was randomly assigned as the intervention group and another as controls. Children's step counts were measured for five consecutive days during school hours at baseline and follow-up. Teachers of the intervention classes led a 10 min activity break in the classroom each day (Bizzy Break!). Mean daily in-school steps for the intervention at baseline and follow-up were 5351 and 5054. Corresponding values for the control group were 5469 and 4246. There was a significant difference in the change in daily steps from baseline to follow-up between groups (p < .05). There was no evidence that girls and boys responded differently to the intervention (p > .05). Children participating in a daily 10 min classroom-based activity break undertake more physical activity during school hours than controls. PMID:23504941

Classroom response systems: What do they add to an active learning environment?  

NASA Astrophysics Data System (ADS)

This study investigated the impact of completely anonymous Classroom Response System (CRS) use on learning outcomes and student attitudes in a large university physical science course for pre-service teachers. As students were expected to have read the textbook prior to class, class time was devoted primarily to conceptual introductions followed by small group discussions of qualitative questions. In the treatment condition, each group provided a single response anonymously using the CRS. The control group responded individually and publicly by show of hands. Responses formed the basis for further discussion in both cases. Anonymity of responses in the control condition was expected to enhance participation and to provide more reliable formative assessment for the instructor, thus enhancing subsequent instruction and learning. The overwhelmingly female study population comprised two course sections with the same instructor. The sections reversed treatment and control group roles for units on Newtonian mechanics and thermodynamics. Students took pre- and posttests for each unit, completed Response System Surveys once and the VASS twice, and submitted weekly mini-reflections and one metareflection. These were analyzed for evidence of attitudes toward science and learning. Whole-class discussions were video-recorded and analyzed for evidence of participation and use of student responses for "just-in-time" teaching. Although CRS use did not improve learning outcomes over the control as measured by pre and posttests, it improved participation, as reflected in the video record and as self-reported by students in reflections, while it was in use. When they were using the CRS, students also indicated greater interest in learning for understanding, as opposed to preferring authoritarian delivery of information by the instructor and opportunities for procedural drills. A framework for classroom interactions emerged. This "C3" framework comprised three dimensions interacting on and through classroom conditions: concerns (performance goals to mastery goals), centeredness (teacher-centered to learner-centered), and control of discourse (traditional lecture to interactive dialogue). These apply to both instructors and students. In previous work, CRS use in classrooms was determined by instructors' positions on these three dimensions. Here, students shifted their centeredness and concerns based on how much the instructor shared the control of classroom discourse.

They report that teachers in urban, rural, and suburban settings nationwide find that these strategies have increased student investment, responsibility, and learning, and decreased problem behaviors. Studies detailing the effectiveness of the program are posted on this website. The basic principles of the program are also described, but the books detailing their approach must be purchased. The newsletter, however, is available free of charge and the archive includes previously published articles, which can be searched by topic, such as technology in the classroom and family involvement.

Plate Boundary Observatory Nucleus Education and Outreach: Bringing GPS and Data- Rich Activities Into College and Secondary Earth Science Classrooms  

NASA Astrophysics Data System (ADS)

Incorporating scientific data into the curriculum provides students with insight into elements of the scientific process such as developing questions and hypotheses, understanding how data are collected, evaluating data quality and limitations, and formulating conclusions based on scientific results (Manduca et al., 2003.) UNAVCO, a geodetic consortium and co-administrator of the Plate Boundary Observatory Nucleus project, seeks to increase public appreciation and understanding of Earth deformation processes and their societal relevance through education and outreach. To that end, we are developing place-based instructional materials for college and secondary Earth science classrooms in which GPS data are used to teach students about plate tectonics. To assess the needs of our users, we conducted interviews with college geoscience faculty from a variety of institution types and focus groups with secondary Earth science teachers to solicit feedback on the types of educational materials that they would likely use in their classrooms. We are engaging members of the scientific and educational communities to develop the materials and are catering the modules to accommodate diverse groups of learners and learning styles. In addition, we have completed and scheduled several professional development opportunities on the local and national levels for college and university faculty and secondary teachers and have created a new education and outreach website. Our education programs are being assessed by an external evaluator. We will present interview and focus group results, report on the status of our education programs, and discuss upcoming UNAVCO education activities.

Beyond the Didactic Classroom: Educational Models to Encourage Active Student Involvement in Learning  

PubMed Central

In a chiropractic college that utilizes a hybrid curriculum model composed of adult-based learning strategies along with traditional lecture-based course delivery, a literature search for educational delivery methods that would integrate the affective domain and the cognitive domain of learning provided some insights into the use of problem-based learning (PBL), experiential learning theory (ELT), and the emerging use of appreciative inquiry (AI) to enhance the learning experience. The purpose of this literature review is to provide a brief overview of key components of PBL, ELT, and AI in educational methodology and to discuss how these might be used within the chiropractic curriculum to supplement traditional didactic lecture courses. A growing body of literature describes the use of PBL and ELT in educational settings across many disciplines, both at the undergraduate and graduate levels. The use of appreciative inquiry as an instructional methodology presents a new area for exploration and study in the academic environment. Educational research in the chiropractic classroom incorporating ELT and appreciative inquiry might provide some valuable insights for future curriculum development.

Accumulation of activated CD4+ lymphocytes in the lung of individuals infected with HIV accompanied by increased virus production in patients with secondary infections.  

PubMed Central

The lung is continuously exposed to infectious and non-infectious agents causing cell activation. Activated cells in the lung such as antigen-presenting cells which harbour HIV may favour this organ as a site for virus production. To test this hypothesis, cells from blood and bronchoalveolar lavage (BAL) of HIV-infected patients and healthy controls were obtained and the activation of the cells were analysed by measuring the expression of IL-2 receptor, HLA-DR and VLA-1. The HIV-infected individuals were subdivided into 'lung symptomatic' or 'lung asymptomatic' patients, depending on the presence or absence of secondary lung diseases besides HIV. All HIV-infected individuals demonstrated a decreased number of CD4+ lymphocytes in blood; however, normal numbers of these cells were found in BAL. The activation state of CD4+ and CD8+ T lymphocytes in blood and BAL was higher in lymphocytes from HIV-infected patients compared with controls. The activation state was highest in the lung symptomatic group. Lung symptomatic patients and lung asymptomatic patients with extrapulmonary infections had increased levels of free virus in plasma. Four out of four individuals without or with only low amounts of cell-free HIV in plasma belonged to the symptom-free subgroup. These results suggest that microorganisms other than HIV may promote viral replication via antigen-driven accumulation and activation of CD4+ cells in the lung or other organs, and thus may be responsible for the loss of helper T cells and the progression of the disease.

Heat shock-triggered Ca2+ mobilization accompanied by pectin methylesterase activity and cytosolic Ca2+ oscillation are crucial for plant thermotolerance.  

PubMed

Apoplastic Ca(2+) concentration controls membrane permeability, cell wall stabilization, and cell integrity; however, little is known about its role in thermotolerance in plants. Here, we report that the acquired thermotolerance of etiolated rice seedlings (Oryza sativa) was abolished by an exogenously supplied Ca(2+) chelator, EGTA, related to increased cellular content leakage during heat shock (HS) treatment. Thermotolerance was restored by the addition of Ca(2+) during EGTA incubation. Pectin methylesterase (EC 3.1.1.11), a cell-wall remodeling enzyme, was activated in response to HS, and its elevated activity was related to the recovery of the HS-released Ca(2+) concentration. EGTA interfered with the capability of HS to increase oscillation of [Ca(2+)]cyt content. We assume that heat-activated PME activity is involved in cell-wall-localized Ca(2+). The removal of apoplastic Ca(2+) might participate in HS signaling to induce HS protein expression and cell-wall remodeling to retain plasma membrane integrity, prevent cellular content leakage and confer thermoprotection.

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

PubMed Central

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. Images

Anti-influenza virus effects of both live and non-live Lactobacillus acidophilus L-92 accompanied by the activation of innate immunity.  

PubMed

The antiviral effects of both a live and non-live Lactobacillus acidophilus strain L-92 (L-92) were investigated by oral administration (10 mg/mouse per d) daily for 21 d in a mouse model infected intranasally with influenza virus (H1N1). Virus titres in the lung of mice administered either live or non-live L-92 cells daily for 15 d were repressed 6 d after virus infection compared with the control group. Natural killer (NK) activity in the orally administered non-live L-92 group was higher compared with that of the control group before virus infection and on day 6. In contrast, NK activity in the live L-92 group compared with the control group was not significantly changed on both days, but was significantly higher on day 1. In contrast, live L-92 showed a greater repression of virus proliferation compared with non-live L-92, 6 d after the infection. Live L-92 decreased the number of neutrophils in the lung and suppressed lung weight, leading to the consequent deterioration of consolidation scores of the lung. These results indicated that pretreatment of live or non-live L-92 cells had protective effects against influenza virus infection. Among the measured cytokines and chemokines, eotaxin, macrophage colony-stimulating factor, IL-1?, RANTES (regulated on activation, normal T cell expressed and secreted) and interferon-? were significantly increased in the lung: IL-17 was significantly increased in Peyer's patch of the live L-92 group compared with the control group. A mechanistic study suggested that the enhancement of NK activity in the lung caused by stimulating various antiviral cytokines and chemokines after the oral administration of L-92 cells might be important in protecting against virus infection.

Visualization of Structural Changes Accompanying Activation of N-Methyl-d-aspartate (NMDA) Receptors Using Fast-scan Atomic Force Microscopy Imaging*  

PubMed Central

NMDA receptors are widely expressed in the central nervous system and play a major role in excitatory synaptic transmission and plasticity. Here, we used atomic force microscopy (AFM) imaging to visualize activation-induced structural changes in the GluN1/GluN2A NMDA receptor reconstituted into a lipid bilayer. In the absence of agonist, AFM imaging revealed two populations of particles with heights above the bilayer surface of 8.6 and 3.4 nm. The taller, but not the shorter, particles could be specifically decorated by an anti-GluN1 antibody, which recognizes the S2 segment of the agonist-binding domain, indicating that the two populations represent the extracellular and intracellular regions of the receptor, respectively. In the presence of glycine and glutamate, there was a reduction in the height of the extracellular region to 7.3 nm. In contrast, the height of the intracellular domain was unaffected. Fast-scan AFM imaging combined with UV photolysis of caged glutamate permitted the detection of a rapid reduction in the height of individual NMDA receptors. The reduction in height did not occur in the absence of the co-agonist glycine or in the presence of the selective NMDA receptor antagonist d(?)-2-amino-5-phosphonopentanoic acid, indicating that the observed structural change was caused by receptor activation. These results represent the first demonstration of an activation-induced effect on the structure of the NMDA receptor at the single-molecule level. A change in receptor size following activation could have important functional implications, in particular by affecting interactions between the NMDA receptor and its extracellular synaptic partners.

Distinct roles of methamphetamine in modulating spatial memory consolidation, retrieval, reconsolidation and the accompanying changes of ERK and CREB activation in hippocampus and prefrontal cortex  

PubMed Central

Drugs of abuse modulated learning and memory in humans yet the underlying mechanism remained unclear. The extracellular signal-regulated kinase (ERK) and the transcription factor cAMP response element-binding protein (CREB) were involved in neuroplastic changes associated with learning and memory. In the current study, we used a Morris water maze to examine the effect of methamphetamine (METH) on different processes of spatial memory in mice. We then investigated the status of ERK and CREB in the hippocampus and prefrontal cortex (PFC). We found that 1.0 mg/kg dose of METH facilitated spatial memory consolidation when it was injected immediately after the last learning trial. In contrast, the same dose of METH had no effect on spatial memory retrieval when it was injected 30 min before the test. Furthermore, 1.0 mg/kg dose of METH injected immediately after retrieval had no effect on spatial memory reconsolidation. Activation of both ERK and CREB in the hippocampus was found following memory consolidation but not after retrieval or reconsolidation in METH-treated mouse groups. In contrast, activation of both ERK and CREB in the PFC was found following memory retrieval but not other processes in METH-treated mouse groups. These results suggested that METH facilitated spatial memory consolidation but not retrieval or reconsolidation. Moreover, activation of the ERK and CREB signaling pathway in the hippocampus might be involved in METH-induced spatial memory changes.

Recovery of heat shock-triggered released apoplastic Ca2+ accompanied by pectin methylesterase activity is required for thermotolerance in soybean seedlings  

PubMed Central

Synthesis of heat shock proteins (HSPs) in response to heat shock (HS) is essential for thermotolerance. The effect of a Ca2+ chelator, EGTA, was investigated before a lethal HS treatment in soybean (Glycine max) seedlings with acquired thermotolerance induced by preheating. Such seedlings became non-thermotolerant with EGTA treatment. The addition of Ca2+, Sr2+ or Ba2+ to the EGTA-treated samples rescued the seedlings from death by preventing the increased cellular leakage of electrolytes, amino acids, and sugars caused by EGTA. It was confirmed that EGTA did not affect HSP accumulation and physiological functions but interfered with the recovery of HS-released Ca2+ concentration which was required for thermotolerance. Pectin methylesterase (PME, EC 3.1.1.11), a cell wall remodelling enzyme, was activated in response to HS, and its elevated activity caused an increased level of demethylesterified pectin which was related to the recovery of the HS-released Ca2+ concentration. Thus, the recovery of HS-released Ca2+ in Ca2+-pectate reconstitution through PME activity is required for cell wall remodelling during HS in soybean which, in turn, retains plasma membrane integrity and co-ordinates with HSPs to confer thermotolerance.

The effect of a Ca(2+) chelator, EGTA, was investigated before a lethal HS treatment in soybean (Glycine max) seedlings with acquired thermotolerance induced by preheating. Such seedlings became non-thermotolerant with EGTA treatment. The addition of Ca(2+), Sr(2+) or Ba(2+) to the EGTA-treated samples rescued the seedlings from death by preventing the increased cellular leakage of electrolytes, amino acids, and sugars caused by EGTA. It was confirmed that EGTA did not affect HSP accumulation and physiological functions but interfered with the recovery of HS-released Ca(2+) concentration which was required for thermotolerance. Pectin methylesterase (PME, EC 3.1.1.11), a cell wall remodelling enzyme, was activated in response to HS, and its elevated activity caused an increased level of demethylesterified pectin which was related to the recovery of the HS-released Ca(2+) concentration. Thus, the recovery of HS-released Ca(2+) in Ca(2+)-pectate reconstitution through PME activity is required for cell wall remodelling during HS in soybean which, in turn, retains plasma membrane integrity and co-ordinates with HSPs to confer thermotolerance.

The decrease in JNK- and p38-MAP kinase activity is accompanied by the enhancement of PP2A phosphate level in the brain of prenatally stressed rats.  

PubMed

Our previous study suggests that in prenatal stress model of depression glucocorticoid receptor (GR) function in adult rats is enhanced. However, the long-term consequences of stress, a causal factor in depression, on intracellular elements involved into the regulation of GR function is poorly examined. Mitogen-activated protein kinases (MAPKs), activity of which is disturbed in depression, are important regulators of GR action, so they can mediate the effect of stress on GR function. Therefore, the aim of the present study was to investigate the levels of active phosphorylated forms of extracellular signal-regulated kinases (ERK), Jun N-terminal kinases (JNK) and the p38 kinase in the hippocampus and frontal cortex in rats subjected to prenatal stress. The concentration of MAP kinase phosphatase (MKP-1, MKP-2) and protein phosphatase-2A (PP2A), which dephosphorylate all forms of MAP kinases, were also determined. During verification of the applied model of depression, we found that prenatally stressed rats displayed high level of immobility in the Porsolt test and that the administration of imipramine, fluoxetine, mirtazapine and tianeptine for 21 days normalized this parameter. Western blot study revealed that rats subjected to prenatal stress had decreased levels of p-JNK1 and p-JNK2 in the hippocampus and p-p38 in the frontal cortex, but the concentrations of p-ERK1 and p-ERK2 were not changed. Chronic treatment with imipramine inhibited the stress-induced decrease in p-JNK1/2, while imipramine, fluoxetine and mirtazapine blocked changes in p-p38. PP2A phosphatase level was higher in the hippocampus and frontal cortex in prenatally stressed animals than in control rats. Chronic treatment with antidepressant drugs attenuated the stress-induced increase in the level of this phosphatase, but had no effect on its concentration in control animals. There was no significant difference in MKP-1 and in MKP-2 levels in both brain structures between control and prenatally stressed rats. The obtained results showed that prenatal stress decreased the levels of active form of JNK and p38, but enhanced PP2A phosphatase expression and most of these changes were reversed by antidepressant drugs. Since p-JNK and p-p38 are known to inhibit GR function their lowered levels may enhance glucocorticoid action. Furthermore, the increased PP2A concentration may intensify GR action not only by inhibition of JNK and p38 phosphorylation, but also by a direct influence on the process of GR translocation.

In vitro detergent activation of lysosomal acid beta-glucosidase in the spleen of normal and type 1 Gaucher patients is not accompanied by change in aggregation state.  

PubMed

The genetic defect in Gaucher disease consists in a deficiency of a membrane-bound lysosomal acid beta-glucosidase. Using the radiation inactivation method, we have previously reported a subunit coupling of the mutated acid beta-glucosidase from Gaucher type 1 spleen in contrast to the normal one (Maret, A., Potier, M., Salvayre, R. and Douste-Blazy, L. (1983) FEBS Lett. 160, 93-97). We have used the same method to determine the effect of detergents on subunit coupling or uncoupling of acid beta-glucosidase in normal and Gaucher spleens. The hypothesis that detergent activation of beta-glucosidase could be due to subunit association or dissociation has been tested. The radiation inactivation size of beta-glucosidase in absence of detergent was 71,000 and 135,500 for normal and Gaucher spleen, respectively, whereas the corresponding values in presence of detergent were 84,000 and 169,000. The higher values obtained in the presence of detergent are incompatible with association or dissociation of subunits but correspond to the increase generally observed for proteins irradiated in the presence of Triton X-100.

Nursing-induced somatosensory cortex plasticity: temporally decoupled changes in neuronal receptive field properties are accompanied by modifications in activity-dependent protein expression.  

PubMed

This study is an attempt to gain insight into the malleability of representational maps in the primary somatosensory cortex in relation to the expression of proteins involved in inhibitory and excitatory neurotransmitter systems that contribute to maintain these maps in a dynamic state. Malleability of somatosensory maps is characterized by changes in the sizes of neuron receptive fields (RFs) affecting the representational grain and in the locations and submodalities of these RFs modifying the map extent. The concomitance of these alterations remains so far hypothetical. We used nursing as an evolving source of ethologically significant cutaneous stimulation. This cyclic behavior is particularly suited to investigating the time course of experience-dependent cortical changes. Electrophysiological maps of the ventrum skin were recorded twice in the same lactating rats between nursing initiation and several weeks after nursing. We found that reduction in RF size occurred earlier than map expansion. As nursing time declined, the map expansion was maintained longer than the RF sharpening. Based on this difference in time course, we compared the expression patterns of several activity-dependent proteins in relation to the RF plasticity. Western blot analysis showed an increase in glutamic acid decarboxylase expression that was concomitant with RF contraction. In contrast, NR2A subunit of NMDA and alpha calcium/calmodulin kinase type II were upregulated at times when map expansion was observed. We propose that inhibitory and excitatory plasticity mechanisms operating with different time courses may contribute to the temporal dissociation of nursing-induced RF reshaping and map expansion.

The stress state of the region around Inönü-Eski?ehir. Active Fault System; interpretations derived from kinematic analysis accompanied with the TUTGA data  

NASA Astrophysics Data System (ADS)

The Central parts of the Anatolian block plays role of stress transferring zone between East Anatolian contractional province and Aegean extensional region in the west during its driven towards west along North and East Anatolian Fault systems. Because of this, various stress regimes characterize and control the different subregions of the Central Anatolia and this situation is reflected by the seismicity of subregions. However the much of the subregions are characterized by strike-slip faultings, the orientations and the trends of the stess tensors are apart from each other. The northwestern part of the Central Anatolia is experienced by ?nönü-Eski?ehir Fault System which creates a complex stress region with the interactions of the North Anatolian Fault System situated in close north. The ?nönü-Eski?ehir Fault System is a WNW-ESE striking right-lateral strike-slip deformational area with a normal component that extends from Uluda? in the west to Sivrihisar in the east and separates the western Anatolia extensional region from the central Anatolia to the northeast. This fault system consists of E-W- and NW-SE-trending fault sets and segments which have potential to produce earthquakes in a wide range of magnitutes. Different aged and typed strike-slip basins appear around the Inonu-Eskisehir fault system. One of them is Mahmudiye-Cifteler-Emirdag basin. The Mahmudiye-Cifteler-Emirdag basin is a fault-controlled pull-apart basin in 85 km length and 25 km average width, extending in northwest-southeast trend from Yürükkaracaören village in the North to Emirdag in the South. Because of the recorded GPS data are inadequate for determining characters of the the low velocity deformation in the studied area, the strain rates are computed by using the velocity vectors from TUTGA data. TUTGA network has been established between 1997 and 1999 as covering the Anatolian block, and considering the deformation acquired by means of active tectonic movements of Turkey by determining the coordinate changes at selected particular points. The coordinate variations of the particular points via tectonic plate movements are caused by inter seismic, co seismic, and post seismic effects. 5 TUTGA data are acquired from the General Command of Mapping-Turkey in this study. The obtained construction rate for the studied area is about 65 +- 15 Nanostrain/yr, which corresponds to a contraction rate of 0.9 mm/yr over 10 km. The strain rate results comprising the last ten years calculated from the TUTGA99 data point to a compression in NW-SE trend in the region. This strain rate and orientations are confirmed by the characters of the faults of the ?nönü-Eski?ehir Fault System. Key Words: ?nönü-Eski?ehir Fault System, Mahmudiye-Çifteler-Emirda? Basin, TUTGA

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.

More Than Science Fair Fun: Poster Session as an Experiential Learning Activity in the Classroom  

NSDL National Science Digital Library

Poster sessions are a common activity at technical conferences, offering authors an opportunity to present their work in this medium and easily establish a dialogue with their colleagues. Students entering college often have a perception that posters were an activity they left behind at the junior- high or high school science fair. This experiential learning activity re-introduces posters and the poster session as an important and effective way to communicate technical information. A simulated technical conference poster session has been developed and implemented as a required class activity within the one-semester, basic Materials Science course. In order to maximize the benefit to the students and achieve the environment necessary for this learning activity, the logistics for the poster session will be outlined. Assessment of the poster session will be presented from both the instructor and students point of view. To date, the qualitative assessment results show students have a positive opinion on this activity and a better understanding of this presentation medium for technical communication. Assessment by the instructor is highlighted by observations of students- teaching- students and the students ability to use the language of materials science in both the written information on their posters and in the oral dialogue with their peers about their selected applications or topics.
