1. Mortality of primates due to roads and power lines in two forest patches in Bangladesh
ABSTRACT Primates are in imminent risk of extinction due to different types of anthropogenic activities. Mortality due to road accidents and electrocution from power lines are among the major direct anthropogenic threats to the survival of primates. We collected primate mortality data from 2015 to 2017 at Lawachara National Park and Satchari National Park in

2. Analysis of the brazilian federal bridge inventory
Resumo A gestão de pontes promove suporte na tomada de decisões gerenciais, otimizando as intervenções necessárias sob limitações orçamentárias. Nessa perspectiva, o Departamento Federal de Transportes (DNIT) desenvolveu o Sistema Brasileiro de Gerenciamento de Pontes (SGO) e promoveu o mais abrangente inventário de pontes rodoviárias sob sua admi

3. A multidisciplinary approach for the management of hypodontia: case report
Hypodontia is the congenital absence of one or more teeth and may affect permanent teeth. Several options are indicated to treat hypodontia, including the maintenance of primary teeth or space redistribution for restorative treatment with partial adhesive bridges, tooth transplantation, and implants. However, a multidisciplinary approach is the most importan

4. Identification of pathology in brigdes in the city and in the country in the county of Campinas-SP / Identificação de patologias em pontes de vias urbanas e rurais no municipio de Campinas-SP
A existência de um grande número de pontes com problemas patológicos importantes motiva a pesquisa sobre este assunto. As pontes de pequeno e médio porte têm relevância significativa para o desenvolvimento econômico e social do país, pois devem assegurar o trânsito de pessoas, veículos e matérias primas e escoamento dos produtos gerados. No entant

5. AVALIAÇÃO DA INTEGRIDADE ESTRUTURAL DE PONTES METÁLICAS DA FERROVIA TURÍSTICA OURO PRETO/MARIANA (MG) POR MEIO DE MODELAGEM NUMÉRICA E TÉCNICAS LABORATORIAIS
With the recuperation of the national railroad system in mind, a study of the pathological phenomena that occur in metallic railroad bridges was performed. These phenomena, such as: corrosion, fatigue cracks, loose connections and deformation and/or excessive displacement of the structural elements, are the principal factors responsible for bridge interventi

6. Folding autonomy of the kringle 4 fragment of human plasminogen.
Kringle 4, an 88-residue plasminogen fragment carrying a lysine-binding site, loses its affinity for lysine-Sepharose upon reductive cleavage of its disulfide bridges. Aerobic incubation of the reduced, denatured fragment results in the rapid restoration of the disulfide bonds with concomitant recovery of lysine-Sepharose affinity. The ability of the unfolde

7. Ku is required for telomeric C-rich strand maintenance but not for end-to-end chromosome fusions in Arabidopsis
Telomere dysfunction arising from mutations in telomerase or in telomere capping proteins leads to end-to-end chromosome fusions. Paradoxically, the Ku70/80 heterodimer, essential for nonhomologous end-joining double-strand break repair, is also found at telomeres, and in mammals it is required to prevent telomere fusion. Previously, we showed that inactivat

8. The role of MgADP in force maintenance by dephosphorylated cross-bridges in smooth muscle: a flash photolysis study.
The effect of [MgADP] on relaxation from isometric tension, initiated by reducing free [Ca2+] through photolysis of the caged photolabile Ca2+ chelator diazo-2, was determined at 20 degrees C in alpha-toxin permeabilized tonic (rabbit femoral artery, Rf) and phasic (rabbit bladder, Rb) smooth muscle. In Rf, the shape of the relaxation curve was clearly bipha

9. The effects of MgADP on cross-bridge kinetics: a laser flash photolysis study of guinea-pig smooth muscle.
1. The effects of MgADP on cross-bridge kinetics were investigated using laser flash photolysis of caged ATP (P3-1(2-nitrophenyl) ethyladenosine 5'-triphosphate), in guinea-pig portal vein smooth muscle permeabilized with Staphylococcus aureus alpha-toxin. Isometric tension and in-phase stiffness transitions from rigor state were monitored upon photolysis of

10. Mre11 Deficiency in Arabidopsis Is Associated with Chromosomal Instability in Somatic Cells and Spo11-Dependent Genome Fragmentation during Meiosis
The Mre11/Rad50/Nbs1 complex is involved in many aspects of chromosome metabolism. Aberrant function of the complex is associated with defects in the DNA checkpoint, double-strand break repair, meiosis, and telomere maintenance. In this article, we report the consequences of Mre11 dysfunction for the stability of mitotic and meiotic chromosomes in Arabidopsi

11. The Regulation of Gelation of Phloem Exudate from Cucurbita Fruit by Dilution, Glutathione, and Glutathione Reductase
The average glutathione equivalent concentration in phloem exudate collected from squash fruit (Cucurbita moschata [Duchesne] Poir. var Butternut) and pumpkin fruit (Cucurbita pepo [L.] var Jack-o-lattern) was 1.02 and 0.60 millimolar, respectively. Glutathione reductase (EC 1.6.4.2) activity in phloem exudate from squash and pumpkin fruit averaged 0.48 and

12. Force-dependent and force-independent heat production in single slow- and fast-twitch muscle fibres from Xenopus laevis.
1. The origin of labile heat production, i.e. a heat component which rapidly decays after the onset of stimulation, and of stable (maintenance) heat production was investigated in intact single fast-twitch (type 1) and slow-twitch (type 3) iliofibularis muscle fibres from Xenopus laevis, at 20 degrees C, by varying stimulation frequency and by varying sarcom
