Touch and Massage for Medically Fragile Infants
Karen Livingston,Shay Beider,Alexis J. Kant,Constance C. Gallardo,Michael H. Joseph,Jeffrey I. Gold
Evidence-Based Complementary and Alternative Medicine , 2009, DOI: 10.1093/ecam/nem076
Abstract: Research investigating the efficacy of infant massage has largely focused on premature and low birth weight infants. The majority of investigations have neglected highly acute patients in academic neonatal intensive care units (NICUs). The current study was developed with two aims: (Phase 1) to develop, implement and demonstrate the feasibility and safety of a parent-trained compassionate touch/massage program for infants with complex medical conditions and (Phase 2) to conduct a longitudinal randomized control trial (RCT) of hand containment/massage versus standard of care in a level III academic Center for Newborn and Infant Critical Care (CNICC). Certified infant massage instructors (CIMIs) taught parents to massage their hospitalized infants. Massage therapy and instruction were performed for seven consecutive days and health outcomes were collected for up to 1 month following treatment. Caregivers, nurses and certified infant massage therapists indicated moderate to high levels of satisfaction and feasibility with the implementation of hand containment/massage in a level III academic center CNICC. In addition, infant behavioral and physiological measures were within safe limits during the massage sessions. All caregivers participating in the massage group reported high levels of satisfaction 7 days into the intervention and at the 1-month follow-up with regards to their relationship with their infant, the massage program's impact on that relationship and the massage program. Due to unequal and small sample sizes, between group analyses (control versus massage) were not conducted. Descriptive infant characteristics of health outcomes are described. Preliminary data from this study indicates feasibility and safety of infant massage and satisfaction among the caregivers, CIMIs and the nurses in the CNICC. An important contribution from this study was the demonstration of the infants' safety based on physiological stability and no change in agitation/pain scores of the infants receiving massage. Massage in a tertiary urban academic NICU continues to be an area of needed study. Future studies examining infant health outcomes, such as weight gain, decreased length of hospitalization and caregiver–infant bonding, would provide greater insight into the impact of massage for medically fragile infants.
A simplification of D'Alarcao's idempotent separating extensions of inverse semigroups
Constance C. Edwards
International Journal of Mathematics and Mathematical Sciences , 1978, DOI: 10.1155/s0161171278000393
Abstract: In [2] D'Alarcao states necessary and sufficient conditions for the attainment of an idempotent-separating extension of an inverse semigroup. To do this D'Alarcao needed essentially three mappings satisfying thirteen conditions. In this paper we show that one can achieve the same results with two mappings satisfying eight conditions.
Social Linguistics and Literacies: Ideology in Discourses. Social Linguistics and Literacies: Ideology in Discourses.

Ilha do Desterro , 2008,
Abstract: Many people in "literate" societies, when asked to define literacy, almost always do so in terms of reading and writing abilities. This narrow interpretation of literacy, an offspring of reductionist psychology, has reigned supreme in many academic and educational contexts for decades, greatly shaping literacy theories and classroom practices. Within the past ten years, however, a large body of multidisciplinary research has begun to undermine the authority of this perspective by situating literacy in larger social practices.

Assessment and Monitoring Damage by Coraebus florentinus (Coleoptera: Buprestidae) in Mediterranean Oak Forests  [PDF]
Ana M. Cárdenas, Patricia Gallardo
Open Journal of Ecology (OJE) , 2018, DOI: 10.4236/oje.2018.85020
Abstract: Coraebus florentinus (Herbst) is a wood borer beetle that damages the most abundant Quercus species making up the Mediterranean forests. Damage is due to the feeding activity of the larvae which cuts the sap flow into the branch where it develops, drying it. In the last decades, the geographical range and the damage records of this species have expanded northwardly as a result of the climate global change since warmer conditions favor higher reproduction and quicker development of this species. On this paper, historical series of data after ten years evaluating damages by C. florentinus in Hornachuelos Natural Park (Southern Spain) are analyzed under the perspective of the environmental temperature increase linked to the global climate change. The assessment was done between 2007 and 2017, in two sampling plots of Mediterranean mixed-oak forests where holm and cork oaks are the predominant tree species. Results show that the infestation levels of this species at the beginning of the assessment period were higher than those described previously in the nineties and that they increased progressively during the monitoring time. The results also agree with the expansion of its distribution areas noticed in other areas of Europe. The foreseeable rising of damages of C. florentinus is discussed, at greater scale, under the perspective of future scenery of environmental warming and oaks decaying by losing fitness due to higher soil aridity.

A Hybrid Photoreceptor Expressing Both Rod and Cone Genes in a Mouse Model of Enhanced S-Cone Syndrome
Joseph C Corbo,Constance L Cepko
PLOS Genetics , 2005, DOI: 10.1371/journal.pgen.0010011
Abstract: Rod and cone photoreceptors subserve vision under dim and bright light conditions, respectively. The differences in their function are thought to stem from their different gene expression patterns, morphologies, and synaptic connectivities. In this study, we have examined the photoreceptor cells of the retinal degeneration 7 (rd7) mutant mouse, a model for the human enhanced S-cone syndrome (ESCS). This mutant carries a spontaneous deletion in the mouse ortholog of NR2E3, an orphan nuclear receptor transcription factor mutated in ESCS. Employing microarray and in situ hybridization analysis we have found that the rd7 retina contains a modestly increased number of S-opsin–expressing cells that ultrastructurally appear to be normal cones. Strikingly, the majority of the photoreceptors in the rd7 retina represent a morphologically hybrid cell type that expresses both rod- and cone-specific genes. In addition, in situ hybridization screening of genes shown to be up-regulated in the rd7 mutant retina by microarray identified ten new cone-specific or cone-enriched genes with a wide range of biochemical functions, including two genes specifically involved in glucose/glycogen metabolism. We suggest that the abnormal electroretinograms, slow retinal degeneration, and retinal dysmorphology seen in humans with ESCS may, in part, be attributable to the aberrant function of a hybrid photoreceptor cell type similar to that identified in this study. The functional diversity of the novel cone-specific genes identified here indicates molecular differences between rods and cones extending far beyond those previously discovered.
The 'RASor's' edge: Ras proteins and matrix destruction in arthritis
Adam C Schmucker, Constance E Brinckerhoff
Arthritis Research & Therapy , 2009, DOI: 10.1186/ar2840
Abstract: In a recent issue of Arthritis Research & Therapy, Abreu and colleagues [1] demonstrate that the Ras guanine nucleotide exchange factor (GEF) RasGRF1 regulates production of matrix metalloproteinase-3 (MMP-3) (stromelysin) in synovial cells taken from the joints of patients with rheumatoid arthritis (RA). The data suggest that overexpression of RasGRF1 activates signal transduction pathways that target the MMP-3 gene, thereby contributing to joint destruction in RA. In addition to measuring MMP-3 expression, they measured levels of the interstitial collagenase, MMP-1, and several other genes involved in RA. Interestingly, production of MMP-1 and MMP-3 in RA, but not non-RA (osteoarthritis and reactive arthritis), synovial tissue correlated positively with expression of RasGRF1 and co-localized in cells expressing RasGRF1. In addition, locked nucleic acid (LNA)-mediated knockdown of RasGRF1 abrogated MMP-3 levels but failed to affect MMP-1, thus demonstrating disparate regulation of these two MMPs. The study raises several noteworthy issues, some of which the authors themselves pointed out.The first is the similarity between the proliferative and invasive characteristics of both RA synovium and cancer [2]. In the present study, the parallel between RA and cancer is further demonstrated by Ras, a classic oncogene, as a signaling molecule in RA fibroblast-like synoviocytes. The Ras superfamily of small GTPases is perhaps best known for linking external mitogenic stimuli to internal signal transduction pathways, leading to changes in gene expression affecting cell proliferation and survival. Upstream signaling events activate GEFs, which mediate the exchange of GDP (on inactive Ras) for GTP, thus causing a conformational change to an active state and interaction with downstream effectors. GTP-bound Ras is inactivated by its intrinsic GTPase capability, which hydrolyzes GTP to GDP, and is aided by GTPase-activating proteins that stimulate the GTPase activity [3].Increase
Muon Transverse Ionization Cooling: Stochastic Approach
Richard C. Fernow,Juan C. Gallardo
Physics , 1995, DOI: 10.1103/PhysRevE.52.1039
Abstract: Transverse ionization cooling of muons is modeled as a Brownian motion of the muon beam as it traverses a Li or Be rod. A Langevin like equation is written for the free particle case (no external transverse magnetic field) and for the case of a harmonically bound beam in the presence of a focusing magnetic field. We demonstrate that the well known muon cooling equations for short-absorbers can be extrapolated to the useful case of a long absorber rod with a focusing magnetic field present.
Ruthenium Carbene Mediated Metathesis of Oleate-Type Fatty Compounds
Bassie B. Marvey,Constance K. Segakweng,Manie H. C. Vosloo
International Journal of Molecular Sciences , 2008, DOI: 10.3390/ijms9040615
Abstract: The complexes RuCl2(PCy3)2(=CHPh), 1, and RuCl2(PCy3)(H2IMes)(=CHPh), 2, proved to be active catalysts for the self-metathesis of oleate-type fatty compounds containing the ester, hydroxyl, epoxy and carboxylic acid functional groups. At elevated reaction temperatures 2 showed a higher activity, stability and lower selectivity for primary metathesis products compared to 1. A profound influence of organic functional groups on catalyst activity and selectivity was found and from relative activities and selectivities 2 has proved to be more resistant to deactivation by polar functional groups and more inclined to promote double bond isomerisation than 1. The observed catalyst deactivation by oxygen-containing functional groups could be attributed to a phosphine displacement side reaction.
