    2005-12-01

    The Malama I Ka `Aina Project (Caring for the land, or sustainability) aims to improve and expand the education of Hawai`i's children by developing and disseminating standards-based, culturally relevant science curricular materials based on an understanding and appreciation of the ways in which traditional Hawaiians interacted with their environment for sustainability. Key concepts include the role of water and the ahupua`a (traditional Hawaiian system of land management), and a culture-based sense of place that includes knowledge of and connection to the land. Elementary, middle, high school and University of Hawai`i teachers work together to develop and implement curricula that are especially relevant to a particular school's science program and issues, e.g., invasive species, students, community and/or geographical location. Participants (typically a mix of teachers, education majors and science majors) enroll in Malama I Ka `Aina, a three-credit course offered through the University of Hawai`i`s Dept. of Curriculum Studies and applicable toward a Bachelor's or Master's degree. This course (team taught by scientists, cultural experts and educational professionals) enables participants to: (1) Study Hawai`i`s unique geology, geography and environmental issues in the context of Hawaiian culture and post Western contact; (2) Use course knowledge to develop, teach and assess Hawaii-oriented, project-based, inquiry activities that address the Hawaii Science Content Standards; (3) Gain an appreciation for the scientific method, and the curiosity that drives science (4) Use educational technology such as PowerPoint, graphing packages and web authoring software to develop electronic resources for educational activities. A sample of the lessons developed by course participants can be found on http://malama.hawaii.edu/schools/index2.html. This project is based at the University of Hawai`i College of Education and funded by an award to P. Chinn by the US Department of

  2. Low oxygen tension induces positive inotropy and decreases a(i)Na in isolated guinea-pig cardiac ventricular papillary muscles.

    Effects of low oxygen on contractile force, intracellular Na+ activity (aiNa), and action potential were simultaneously measured in isolated guinea-pig ventricular papillary muscles. Reduction of oxygen from control 488 to 150 mmHg biphasically increased and decreased the twitch tension, and decreased aiNa in muscles driven at 60 beats/min. The action potential duration (APD) was decreased but the maximum rate of upstroke (Vmax) was increased. In control, 1 microM epinephrine significantly increased the the action potential amplitude and twitch tension with decreases in the time to twitch peak (TTP), time for 50% relaxation (RT50), and aiNa. After exposure to low oxygen for 10 min, with twitch tension elevated and TTP and RT90 increased, 1 microM epinephrine significantly increased the twitch tension and Vmax, and decreased the APD and aiNa. Pretreatment with reserpine inhibited the twitch tension, both at control and in the presence of epinephrine. But changes of action potential and aiNa in response to low oxygen and epinephrine were similar to those in control. Our results indicate that the isolated guinea-pig ventricular muscle needs a high oxygen tension to maintain a normal contractile function. Reduction of oxygen deteriorates the electrical and mechanical activities, most likely, by a coaxial graded hypoxia. The decreased aiNa, not associated with endogenous catecholamines, suggests that the activity of the Na(+)-K+ pump can be maintained in the superficial muscle cells despite of core-central hypoxia.

    2014-01-01

    Alcohol use and the resulting problems associated with high-risk drinking in the American Indian/Native Alaskan (AI/NA) population are well-documented, as alcohol misuse has taken an incredible toll on many AI/NA communities. Presently, both overall health issues and alcohol use occur disproportionately within this population. This article provides an updated overview of the impact of alcohol use in the United States and within AI/NA communities specifically. It also provides recommendations for an alcohol-related screening and brief intervention instrument that social workers can begin using in their practice and can be utilized within the AI/NA community.

  16. Influence of sodium-hydrogen exchange on intracellular pH, sodium and tension in sheep cardiac Purkinje fibres.

    PubMed Central

    Kaila, K; Vaughan-Jones, R D

    1987-01-01

    1. The influence of sarcolemmal Na+-H+ exchange upon intracellular Na+ activity (aiNa), intracellular pH (pHi), extracellular surface pH (pHs) and tonic tension was investigated in sheep cardiac Purkinje fibres. Intracellular ion activities were measured with liquid sensor ion-selective micro-electrodes. A two-micro-electrode voltage-clamp was also used to control membrane potential while simultaneously recording tonic tension. 2. Inhibition of the sarcolemmal Na+-K+ pump by strophanthidin (10 mumol/l) produced a rise in aiNa, an increase in [Ca2+]i as evidenced by a rise in tonic tension, and a fall in pHi of 0.1-0.3 units. The intracellular acidosis has been shown previously to be linked to the rise in [Ca2+]i (Vaughan-Jones, Lederer & Eisner, 1983). 3. Amiloride (1-2 mmol/l), an inhibitor of Na+-H+ exchange, produced a small reversible decrease in pHi and aiNa. Both effects became more pronounced in strophanthidin-exposed fibres. In addition, pHi decreased during application of strophanthidin and this decrease was reversibly inhibited by amiloride. It is concluded that sarcolemmal Na+-H+ exchange is stimulated following inhibition of the Na+-K+ pump. 4. In strophanthidin-exposed fibres, a rise in [Ca2+]i resulted in an intracellular acidosis which could still be observed in the presence of amiloride (1 mmol/l). This suggests that the fall in pHi was not caused by a modulatory effect of [Ca2+]i on sarcolemmal Na+-H+ exchange. 5. Tetrodotoxin (TTX) produced a small fall in aiNa (ca. 0.5 mmol/l) which was not augmented in the presence of strophanthidin. Furthermore, the effects on aiNa of TTX and amiloride were additive. Thus the influence of amiloride on aiNa does not involve blockade of voltage-gated Na+ channels. 6. The stoicheiometry of Na+-H+ exchange, estimated from the rates of change of pHi and aiNa in amiloride, appeared to be electroneutral (1:1). The stoicheiometry was unaffected by changes in pHi. 7. In strophanthidin-exposed fibres (i.e. aiNa is

  17. Intracellular ion activities in frog skin in relation to external sodium and effects of amiloride and/or ouabain.

    PubMed Central

    Harvey, B J; Kernan, R P

    1984-01-01

    Intracellular activities of sodium, potassium and chloride ions, aiNa, aiK, and aiCl were measured with ion-selective single-, double- and triple-barrelled micro-electrodes in skin and isolated epithelia of Rana temporaria bathed on both sides with normal or modified physiological saline. Apical and basolateral membrane potentials, psi ac and psi cs and resistance Ra and Rb respectively were also measured and from the latter the fractional resistance of the apical membrane, F(Ra) and voltage divider ratio, delta psi ac/delta psi cs were measured as criteria of satisfactory membrane penetration by the micro-electrodes. Under control conditions, aiNa was 12.3 +/- 0.8 mM, aiK was 70.3 +/- 22 mM and aiCl was 20.3 +/- 1.6 mM with psi ac averaging -38.0 +/- 3.2 mV. When 10(-4) M-amiloride was added to the apical bathing fluid aiNa fell within 10 min to 1.18 +/- 0.1 mM and aiCl to 5.2 +/- 0.9 mM, while aiK increased to 86.2 +/- 3.8 mM as measured from the basolateral border of isolated epithelia. The sodium transport pool of the skin was measured from the fall in aiNa in the presence of amiloride and could be expressed as 33 X 10(-9) mol cm-2 of epithelium. The mean rate of fall of aiNa under these conditions corresponded to an efflux rate at the basolateral border of 30.1 X 10(-9) mol cm-2 min-1 (48 microA cm-2) giving a half-time for turnover of the sodium transport pool of 33 s. Reduction of sodium concentration in the apical fluid from the normal 79 mM-Na to 10, 1 and 0.1 mM caused aiNa to fall in stages to 2 mM. Because psi ac increased in negativity to -101 mV in the process, this driving force for passive sodium accumulation, more than offset the increased sodium gradient opposing sodium influx across the apical border.

  19. Apical membrane permeability and kinetic properties of the sodium pump in rabbit urinary bladder.

    PubMed Central

    Lewis, S A; Wills, N K

    1983-01-01

    Previous studies have shown that aldosterone stimulates the rate of Na+ transport across the rabbit urinary bladder epithelium by increasing the apical membrane permeability to Na+. Paradoxically, ion-sensitive and conventional micro-electrode measurements demonstrated that intracellular Na+ activity aiNa+ was essentially unchanged by aldosterone, i.e. aiNa+ was constant regardless of the rate of Na+ transport. The present study was designed to resolve this apparent contradiction. The effects of elevated, endogenous aldosterone levels produced by low-Na+ diet (Lewis & Diamond, 1976) on urinary bladder Na+ transport were investigated in vitro using Ussing-type chambers and intracellular conventional and ion-sensitive microelectrodes. Apical membrane selectivity and kinetics of the Na+ pump were assessed as a function of hormone stimulation. The aldosterone-stimulated increase in Na+ transport was accounted for by increases in both the relative selective permeability of the apical membrane to Na+ and an increase in its absolute Na+ permeability. The kinetics of the Na+ pump were evaluated electrically by loading the cells with Na+ (monitored with Na+-sensitive micro-electrodes) or alternatively by manipulating serosal solution K+ concentration and measuring changes in the basolateral membrane electromotive forces and resistance. From these measurements the current generated by the pump was calculated as a function of intracellular Na+ or extracellular K+. The kinetics of the pump were not altered by aldosterone. A model of highly co-operative binding estimated Km for Na+ as 14.2 mM and 2.3 mM for K+. Hill coefficients for these ions were 2.8 and 1.8, respectively, consistent with a pump stoichiometry of 3 Na+ to 2 K+. The kinetic properties of the Na-K pump indicate that physiological levels of aiNa+ are poised at the foot of a step kinetic curve which energetically favours Na+ extrusion. PMID:6312027

  1. The negative inotropic effect of raised extracellular potassium and caesium ions on isolated frog atrial trabeculae.

    PubMed

    Chapman, R A; Rodrigo, G C

    1987-10-01

    The exposure of frog atrial trabeculae to Ringer solution containing an elevated K+ concentration, produces a depolarization of the membrane and a reduction of both the duration of the action potential and the strength of the heart beat. In voltage-clamped preparations, the effect of perfusion with K+-rich Ringer solution is threefold. First, a sustained inward current develops at the holding potential (-80 mV). Secondly, the contractions evoked by depolarizing clamp pulses are reduced: this effect which is greater upon the tonic phase of the contraction than the early phasic tension, is also seen to follow the addition of Cs+ ions to the bathing fluid; at equal concentrations K+ ions are the more effective. Thirdly, when measured with an ion-sensitive micro-electrode in ventricular trabeculae, the intracellular Na+ ion activity (aiNa) declines with a time course similar to the development of the negative inotropic effect. This suggests that the actions of raised [K+]o or [Cs+]o upon tension may be secondary to an effect on the movement of Na+ ions across the cell membrane, which by reducing aiNa may affect tension by way of the Na-Ca exchange.

  5. Interaction between Na+ and H+ ions on Na-H exchange in sheep cardiac Purkinje fibers.

    PubMed

    Wu, M L; Vaughan-Jones, R D

    1997-04-01

    The interaction between Na+ and H+ ions upon Na-H exchange (NHE) was examined in sheep cardiac Purkinje fibers. Acid equivalent fluxes through NHE were examined using recordings of intracellular pH and Na+ in isolated preparations measured with ion selective microelectrodes. The extent of acid-extrusion by NHE was estimated from pH(i) recovery-rate, multiplied by beta(i) (intracellular buffering power) in response to an internal acid load induced by 20 mm NH4Cl removal (nominally HCO3- free media). A mixed inhibitory effect was found of extracellular H+ on external Na+-activation of NHE (i.e. an increase, at low pH(o), in the apparent Michaelis constant for external Na+ ions [K(Nao)(0.5)] and a decrease in the maximum transport rate [V(Nao)(max)]). In addition, we confirmed that the stoichiometry of Na(o) binding is unaffected by the pH(o) (between 7.5 and 6.5), showing a Hill coefficient close to one. The interaction between Na+ and H+ ions at the internal face of the cardiac NHE was also studied. Our evidence suggests that an increase in the intracellular Na+ ion concentration ([Na+]i) inhibits acid efflux and that this inhibition can be approximated by the decrease in thermodynamic driving force caused by reducing the transmembrane Na+ gradient. It appears, however, that small variations in [Na+]i from the normal resting level (intracellular sodium activity, a(i)Na = 7 to 13 mm) have little or no effect on acid efflux, suggesting that variation of a(i)Na is not a physiologically important controller of NHE activity in heart.

  6. A Na+-activated K+ current (IK,Na) is present in guinea-pig but not rat ventricular myocytes.

    PubMed

    Lawrence, C; Rodrigo, G C

    1999-05-01

    The effects of removing extracellular Ca2+ and Mg2+ on the membrane potential, membrane current and intracellular Na+ activity (aiNa) were investigated in guinea-pig and rat ventricular myocytes. Membrane potential was recorded with a patch pipette and whole-cell membrane currents using a single-electrode voltage clamp. Both guinea-pig and rat cells depolarize when the bathing Ca2+ and Mg2+ are removed and the steady-state aiNa increases rapidly from a resting value of 6.4+/- 0.6 mM to 33+/-3.8 mM in guinea-pig (n=9) and from 8.9+/-0.8 mM to 29.3+/-3.0 mM (n=5) in rat ventricular myocytes. Guinea-pig myocytes partially repolarized when, in addition to removal of the bathing Ca2+ and Mg2+, K+ was also removed, however rat cells remained depolarized. A large diltiazem-sensitive inward current was recorded in guinea-pig and rat myocytes, voltage-clamped at -20 mV, when the bathing divalent cations were removed. When the bathing K+ was removed after Ca2+ and Mg2+ depletion, a large outward K+ current developed in guinea-pig, but not in rat myocytes. This current had a reversal potential of -80+/-0.7 mV and was not inhibited by high Mg2+ or glybenclamide indicating that it is not due to activation of non-selective cation or adenosine triphosphate (ATP)-sensitive K channels. The current was not activated when Li+ replaced the bathing Na+ and was blocked by R-56865, suggesting that it was due to the activation of KNa channels.

  7. Changes of contractile responses due to simulated weightlessness in rat soleus muscle

    1994-08-01

    Some contractile and electrophysiological properties of muscle fibers isolated from the slow-twitch soleus (SOL) and fast-twitch extensor digitorum longus (EDL) muscles of rats were compared with those measured in SOL muscles from suspended rats. In suspendede SOL (21 days of tail-suspension) membrane potential (Em), intracellular sodium activity (aiNa) and the slope of the relationship between Em and log [K]o were typical of fast-twitch muscles. The relation between the maximal amplitude of K-contractures vs Em was steeper for control SOL than for EDL and suspended SOL muscles. After suspension, in SOL muscles the contractile threshold and the inactivation curves for K-contractures were shifted to more positive Em. Repriming of K-contractures was unaffected by suspencion. The exposure of isolated fibers to perchlorate (ClO4-)-containing (6-40 mM) solutions resulted ina similar concentration-dependent shift to more negative Em of activation curves for EDL and suspended SOL muscles. On exposure to a Na-free TEA solution, SOL from control and suspended rats, in contrast to EDL muscles, generated slow contractile responses. Suspended SOL showed a reduced sensitivity to the contracture-producing effect of caffeine compared to control muscles. These results suggested that the modification observed due to suspension could be encounted by changes in the characteristics of muscle fibers from slow to fast-twitch type.

    2005-12-01

    The marvels of modern science often fail to engage indigenous students, as the content and instructional style are usually rooted in the Western experience. This 3 year project, funded by the US Dept. of Education for the Education of Native Hawaiians, offers a curriculum that teaches science through (rather than just about) Native Hawaiian culture. The curriculum focuses on the interdependence of natural resources in our ahupuaa, or watersheds, and helps students strengthen their sense of place and self to malama i ka aina, to care for the land. Further, the curriculum is designed to: engage students in scientific study with relevant, interesting content and activities; improve student achievement of state department of education standards; increase student knowledge and skills in science, math and language arts; respond to the learning needs of Native Hawaiian and/or at-risk students. The project will be presented by a curriculum writer who created and adapted more than a year's worth of materials by teaming with kupuna (respected elders), local cultural experts and role models, educators (new, veteran, Hawaiian, non-Hawaiian, mainland, general and special education teachers), and professionals at the Center on Disability Studies at the University of Hawaii and ALU LIKE, Inc, a non-profit organization to assist Native Hawaiians. The materials created thus far are available for viewing at: www.scihi.hawaii.edu The curriculum, designed for grades 8-11 science classes, can be used to teach a year-long course, a unit, or single lesson related to astronomy, biology, botany, chemistry, geology, oceanography, physical and environmental sciences. This project is in its final year of field testing, polishing and dissemination, and therefore this session will encourage idea sharing, as does our copyright free Web site.

    Plant phenology is a powerful indicator of how climate change affects native ecosystems, and also provides an experiential outdoor learning opportunity for promoting youth conservation education and awareness. We developed a youth conservation education curriculum, including both classroom and field components, for local middle and high school students from Hawaii. The curriculum is focused on linking plant phenology and climate change, with emphasis on ecologically and culturally important native trees and birds at Hakalau Forest National Wildlife Refuge (NWR), on the Island of Hawaii. In this curriculum, students: (i) visit Hakalau Forest NWR to learn about the ecology of native ecosystems, including natural disturbance regimes and the general concept of change in forest ecosystems; (ii) learn about human-induced climate change and its potential impact on native species; and (iii) collect plant phenology measurements and publish these data on the USA National Phenology Network website. This youth conservation education curriculum represents a close collaboration between Hakalau Forest NWR; the Friends of Hakalau Forest NWR; the College of Tropical Agriculture and Human Resources at the University of Hawaii at Manoa; the USDA Forest Service; and Imi Pono no Ka Aina, an environmental education and outreach program for the Three Mountain Alliance Watershed Partnership. In the Winter and Spring of 2011-2012, we developed classroom and field portions of the curriculum. In the Spring and Summer of 2012, we recruited four groups of participants, with a total of ~40 students, who visited the refuge to participate in the curriculum. Preliminary phenology observations based upon ~4 months of measurements show low to medium levels of flowering, fruiting and leaf flush. However, the real science value of this program will come over years to decades of accumulated student activity. From this, we anticipate the emergence of a unique tropical montane forest dataset on plant

    Blaisdell, Richard Kekuni

    1998-01-01

    PURPOSE: To consider the role of culture in the persistently high cancer rates of Kanaka Maoli (Native Hawaiians) in their homeland. METHODS: Historical and recent cancer and other health and socio­economic data and not readily accessible information on Kanaka Maoli and other major ethnicities were analyzed. FINDINGS: In the 1990s, the 205,078 Kanaka Maoli, who comprise 18.8% of the total Ka Pae'aina (Hawaiian Archipelago) population of 1,108,229, continue to have the highest and still rising cancer mortality rates compared to other ethnicities. Rates are higher for piha (pure) Kanaka Maoli than for hapa (mixed) and greater for Kanaka Maoli men over women. The leading cancer sites are lung, breast, stomach, uterus, liver and rectum. Overall five year cancer survival rates for Kanaka Maoli remain shorter than for the other ethnic groups. Kanaka Maoli rank highest for cancer risk factors, such as tobacco use, alcohol use, and obesity; diets high in calories, total fat, saturated fat, cholesterol, processed foods, foods low in fiber, vitamin C, calcium, and folate. Kanaka Maoli continue to have the most unfavorable rates for other leading causes of death, chronic morbidity, suicide, accidents, and other social and economic indicators such as family income, home ownership, schooling, crime and imprisonment. Kanaka Maoli tend to live in rural communities where they comprise 40­90% of the population and where Western health care services are meager and distant. Kanaka Maoli under­utilize Western health care, health promotion and disease prevention services. Kanaka Maoli score poorly in cancer knowledge and tend to have a fatalistic attitude toward cancer. CONCLUSIONS: An interplay of underlying historical, societal and cultural factors, not specific for cancer, nor for ill health, appear to account for the worsening broad plight of Kanaka Maoli. These include: (1) Kanaka Maoli depopulation in

    The simple analysis method has been introduced for the kinetic analysis of the hydrothermal growth. The zinc oxide nanorod arrays have been synthesized via a hydrothermal process. Zinc nitrate hexahydrate (Zn(NO3)2 · 6H2O) has been used as the precursor in the presence of hexamethylenetetramine (C6H12N4) for the formation of ZnO nanostructures. Long-term isothermal growth kinetics of ZnO nanorods has been investigated. The effect of the solution temperature (70-90 ℃) on the kinetics of the hydrothermal growth of ZnO nanorods has been examined. An extensive analysis by scanning electron microscopy, energy dispersive spectroscopy and x-ray diffraction has revealed that the as-synthesized ZnO nanorod arrays are well-crystalline and possessing hexagonal wurtzite structure. These ZnO films have promising potential advantages in microelectronic and optoelectronic applications. Tiek piedāvāta vienkārša analīzes metode kristālu hidrotennālās augšanas kinētikasizpētei. Labi sakārtotu ZnO nanostieņu kopa tika sintezēta pielieto­jot hidrotennālās augšanas metodi, cinka nitrāta heksahidrāta (Zn(NO3)2 · 6H2O) un heksametilēntetramīna (C6H12N4) šķīdumā. Plānās kārtiņas biezuma izmaiņas tika novērotas reālā laikā, pielietojot interferometrijas tehniku. Tika mērīts no sistēmas plānā kārtiņa - pamatne atstarotais lāzerstars; iegūtā interferences aina tika izman­tota plānās kārtiņas biezuma aprēķiniem. ZnO nanostieņu izotermiskās kristalizācijas procesa kinētika tika aprakstīta ar parabolisku likumu. Tika aprēķināts, ka ZnO nanostieņu kopu hidrotennālās augšanas aktivācijas enerģija ir 123kJ/mol. Šī metode ir piemērota viendimensionālas augšanas procesu analīzei un paver jaunas iespējas turpmākiem pētījumiem.

In Memoriam Dr. habil. phys. Inta Muzikante (08.01.1951-15.02.2012) Inta Muzikante Inta was born in Valmiera, a town in the northern part of Latvia. She attended school in Sigulda and high school in Riga. While at the high-school, Inta decided to study natural sciences. After graduating from high-school in 1969 she entered the physics section of the Physics and Mathematics department of University of Latvia and obtained her university degree in 1974. In parallel with University studies, Inta started to work at the Semiconductor Physics Research Lab at the University of Latvia. After graduating she was offered a position at the Physical Energetics institute of the Latvian Academy of Sciences, in the laboratory of Professor Edgars Silinsh, one of the most internationally well known Latvian physicists. Inta started researching electronic and photoelectric processes in organic crystals and thin films. This was a novel field, pioneered both internationally and in Latvia by Profesors E Silinsh, O Neilands and J Freimanis. It could be said that Inta stood at the cradle of this research field and stayed faithful to it all of her life. Her work was very successful and within a few years she advanced from research assistant to researcher and then leading research scientist. Her first scientific topic was studies of the mechanism of charge carrier photogeneration and separation in organic molecular crystals. In 1983 for a work
