13. Expression of IGF-II, IGF-IR, SF-1 and DAX-1 genes in pediatric and adult adrenocortical tumors / Expressão dos genes IGF-II, IGF-IR, SF-1 e DAX-1 em tumores adrenocorticais de crianças e adultos
Introduction: The molecular pathogenesis of adrenocortical tumors is heterogeneous and incompletely understood. Insulin-like growth factor II (IGF-II) overexpression has been demonstrated in adult adrenocortical carcinomas. IGF-II exerts its mitogenic effects through interaction with IGF-I receptor (IGF-IR). In addition, steroidogenic factor 1 gene (SF-1) an

14. Genes associated with hypersensitive response (HR) in the citrus EST database (CitEST)
Plants are continuously exposed to pathogen attack, but successful infection is rare because they protect themselves against pathogens using a wide range of response mechanisms. One of them is the hypersensitive response (HR), which is a form of cell death often associated with plant resistance to pathogen infection to prevent the [email protected] sebpg@c

15. Purificação parcial, propriedades e caracterização cinética de proteases tripsina-like do intestino médio da lagarta da soja, Anticarsia gemmatalis / Partial purification, properties and kinetics characterization of midgut trypsin-like proteases from the velvetbean caterpillar, Anticarsia gemmatalis
The identification and characterization of proteases from the insect midgut are of great importance for research and development pest resistant cultivars of crop species. Different processes of trypsin-like proteases purification from midgut A. gemmatalis and characterization of these proteases were carried out in this work. Two fractions were isolated durin

16. Importância da região AV3V para as respostas pressoras produzidas pela ativação de áreas bulbares.
Cardiovascular responses are integrated at different levels of the central nervous system (CNS). Particularly the hypothalamus and brainstem areas are involved in the control of autonomic responses and among them the cardiovascular responses. Different areas in the brainstem, like the nucleus tract solitarii (NTS), the rostroventrolateral medulla (RVLM), cau

17. Supresión de modos de vibración acústicos con un resonador Helmholtz
The insertion of a Helmholtz resonator (HR) in the lateral walls of a tube containing stationary waves in its interior can be used to suppress one or more resonant modes if one chooses the resonator frequency appropriately. The HR can also operates like a filter for traveling waves. In this case, the HR attenuates the waves in a very selective frequency rang

18. Efeitos da injeção de moxonidina no controle da ingestão de sódio e regulação cardiovascular.
Deficit of water and sodium in the body is detected by receptors located in different parts of the body. These receptors or hormones signalize to specific areas in the brain that control renal responses and water and sodium intake. Among these areas are: organum vasculosum of the lamina terminalis (OVLT), subfornical organ (SFO), anteroventral third ventricl

19. Soybean canopy [Glycine max (L.), Merril photosynthetic pigments estimation by measns of spectral reflectance / Utilização da reflectância espectral para a estimativa de pigmentos fotossintéticos em dosséis de soja [Gycine Max (.L), Merril]
Photosynthetic pigments are essential for plant development, because they are responsible for the incident solar energy absorption used in photosynthesis. Individually quantifying these pigments in great extensions of agricultural crops has been made possible by hyperspectral remote sensing development and these information can be used to produce a more accu

20. Adaptações cardio-respiratorias ao treinamento fisico aerobio em mulheres na menopausa : estudo longitudinal e transversal
Menopause is a special period in a woman?s life when almost all them experience progressive modification in their physical and psychological sates. Among various symptoms, there are those related to the cardiorespiratory system like: intolerance to exertion, skin hyperemia and heart palpitation. The objective of this research, that included a longitudinal an

21. Developmental Defects and Male Sterility in Mice Lacking the Ubiquitin-Like DNA Repair Gene mHR23B
mHR23B encodes one of the two mammalian homologs of Saccharomyces cerevisiae RAD23, a ubiquitin-like fusion protein involved in nucleotide excision repair (NER). Part of mHR23B is complexed with the XPC protein, and this heterodimer functions as the main damage detector and initiator of global genome NER. While XPC defects exist in humans and mice, mutations

22. Cymbidium Ringspot Tombusvirus Coat Protein Coding Sequence Acts as an Avirulent RNA
Avirulent genes either directly or indirectly produce elicitors that are recognized by specific receptors of plant resistance genes, leading to the induction of host defense responses such as hypersensitive reaction (HR). HR is characterized by the development of a necrotic lesion at the site of infection which results in confinement of the invader to this a

23. Self/nonself recognition in ascidian fertilization: Vitelline coat protein HrVC70 is a candidate allorecognition molecule
Ascidians are hermaphrodites releasing sperm and eggs simultaneously, but many species are self-sterile because of a self/nonself-recognition system in spermegg interaction. Here, we show that a 70-kDa vitelline coat protein, HrVC70, consisting of 12 epidermal growth factor-like repeats, plays a key role in self/nonself recognition during ascidian fertilizat

24. Thyrotropin-releasing hormone-like material in the rat retina: changes due to environmental lighting.
Material reacting with an antibody to thyrotropin-releasing hormone (TRH) has been found to be present in the rat retina. The compound present in the retina cochromatographed with authentic TRH and most of its activity was lost when incubated with pyroglutamate aminopeptidase (L-pyroglutamyl-peptide hydrolase, EC 3.4.11.8), an enzyme that degrades TRH. The T
