1. Tityus serrulatus envenoming in non-obese diabetic mice: a risk factor for severity
Abstract Background In Brazil, accidents with venomous animals are considered a public health problem. Tityus serrulatus (Ts), popularly known as the yellow scorpion, is most frequently responsible for the severe accidents in the country. Ts envenoming can cause several signs and symptoms classified according to their clinical manifestations as mild, moder

2. Inicio da nodulacao em sete cultivares de feijoeiro inoculadas com duas estirpes de rhizobium.
A nodulacao precoce e manutencao de nodulos efetivos durante o florescimento do feijoeiro (Phaseolus vulgaris L.) podem favorecer a fixacao biologica do N2 nessa cultura. Dessa forma, procurou-se identificar o potencial de inducao dos genes da nodulacao e o potencial de atracao simbiotica das raizes de sete cultivares de feijoeiro inoculadas com duas estirpe

4. Expressão e reposição estrogenica e androgenica no lobo ventral da prostata de camundongos diabeticos (NOD) frente a terapia insulinica / Androgen and estrogen replacement and expression in the ventral lobe of the prostate of non-obese diabetic mice (NOD) following insulin therapy
Diabetes adversely affects prostate morphology and function through alterations in the hypothalamic-hypophyseal-gonadal axis. Thus, the aims of this study were to characterize morphological, proliferative and immunological features of the prostate of diabetic mice after long term glycemic control and hormonal replacement, and as well as to relate these param

5. Comparison of the effect of ganglioside GM1 and the Nerve Growth Factor (NGF) on the expression of receiver of high affinity for NGF, TrkA and insulin in isolated pancreatic islets of NOD mice (non obese diabetic) / Comparação dos efeitos do gangliosideo GM1 e do fator de crescimento neural (NGF) sobre a expressão de receptor de alta afinidade para NGF, TrkA e insulina em ilhotas pancreaticas isoladas de camundongos NOD (diabetico não obeso)
The non-obese diabetic mice (NOD) lineage is characterized by developing type 1 diabetes mellitus (DM-1) naturally, bearing a similarity to DM-1 in human beings. The spontaneous manifestation of diabetes is characterized by gradual infiltration in pancreatic islets by mononuclear cells lymphocytes T (CD4+ and CD8+) and destruction of the ß-cells producers o

6. Sleep deprivation reduces the lymphocyte count in a non-obese mouse model of type 1 diabetes mellitus
The objective of the present study was to determine whether sleep deprivation (SD) would promote changes in lymphocyte numbers in a type 1 diabetes model (non-obese diabetic, NOD, mouse strain) and to determine whether SD would affect female and male NOD compared to Swiss mice. The number of lymphocytes in peripheral blood after 24 and 96 h of SD (by multipl

7. Effects of GM1 administration on autoimmune diabetes modulation and cytokines expression, Nerve Growth Factor and TrkA receptor in NOD mice (non obese diabetic) / Avaliação dos efeitos da administração do gangliosideo GM1 na modulação do diabetes mellitus autoimune e expressão de citocinas, Nerve Growth Factor e seu receptor TrkA em camundongos NOD (non obese diabetic)
The strain of NOD mice (non obese diabetic) spontaneously develops diabetes mellitus type 1 (DM-1) with strong similarity to the observed in humans. In this model, the diabetes manifestation occurs among 12th and 24th weeks of life, with presence of pancreas-specific autoantibodies. Great part of the cells are CD4+ and CD8+T cells, and even so NK cells, lymp

8. Role of the Differentiation of Root Epidermal Cells in Nod Factor (from Rhizobium meliloti)-Induced Root-Hair Depolarization of Medicago sativa.
The stage of differentiation of epidermal cells and the development of root hairs was found to be important for the induction of depolarization in root hairs of Medicago sativa by Nod factor [NodRm-IV(S)] isolated from the bacterium Rhizobium meliloti. The electrical membrane response was concentration dependent, having its major effect (amplitude of the dep

9. Rhizobium nod factor signaling. Evidence for a g protein-mediated transduction mechanism
Rhizobium nodulation (Nod) factors are lipochitooligosaccharide signals that elicit key symbiotic developmental responses in the host legume root. In this study, we have investigated Nod factor signal transduction in the Medicago root epidermis by using a pharmacological approach in conjunction with transgenic plants expressing the Nod factor-responsive repo

10. Pharmacological Analysis of Nod Factor-Induced Calcium Spiking in Medicago truncatula. Evidence for the Requirement of Type IIA Calcium Pumps and Phosphoinositide Signaling1
Bacterial Nod factors trigger a number of cellular responses in root hairs of compatible legume hosts, which include periodic, transient increases in cytosolic calcium levels, termed calcium spiking. We screened 13 pharmaceutical modulators of eukaryotic signal transduction for effects on Nod factor-induced calcium spiking. The purpose of this screening was

11. Nod Factor Elicits Two Separable Calcium Responses in Medicago truncatula Root Hair Cells1
Modulation of intracellular calcium levels plays a key role in the transduction of many biological signals. Here, we characterize early calcium responses of wild-type and mutant Medicago truncatula plants to nodulation factors produced by the bacterial symbiont Sinorhizobium meliloti using a dual-dye ratiometric imaging technique. When presented with 1 nm No

12. Nod Factor Inhibition of Reactive Oxygen Efflux in a Host Legume1
Hydrogen peroxide (H2O2) efflux was measured from Medicago truncatula root segments exposed to purified Nod factor and to poly-GalUA (PGA) heptamers. Nod factor, at concentrations > 100 pm, reduced H2O2 efflux rates to 60% of baseline levels beginning 20 to 30 min after exposure, whereas the PGA elicitor, at > 75 nm, caused a rapid increase in H2O2 eff
