A connection between extracellular matrix and hormonal signals during the development of the human fetal adrenal gland BJMBR
Chamoux,E.; Otis,M.; Gallo-Payet,N..
The human adrenal cortex, involved in adaptive responses to stress, body homeostasis and secondary sexual characters, emerges from a tightly regulated development of a zone-specific secretion pattern during fetal life. Its development during fetal life is critical for the well being of pregnancy, the initiation of delivery, and even for an adequate adaptation to extra-uterine life. As early as from the sixth week of pregnancy, the fetal adrenal gland is characterized by a highly proliferative zone at the periphery, a concentric migration accompanied by cell differentiation (cortisol secretion) and apoptosis in the central androgen-secreting fetal zone. After birth, a strong reorganization occurs in the adrenal gland so that it better fulfills the newborn's...

A Floricaula/Leafy gene homolog is preferentially expressed in developing female cones of the tropical pine Pinus caribaea var. caribaea Genet. Mol. Biol.
Dornelas,Marcelo Carnier; Rodriguez,Adriana Pinheiro Martinelli.
In angiosperms, flower formation is controlled by meristem identity genes, one of which, FLORICAULA (FLO)/LEAFY (LFY), plays a central role. It is not known if the formation of reproductive organs of pre-angiosperm species is similarly regulated. Here, we report the cloning of a conifer (Pinus caribaea var. caribaea) FLO/LFY homolog, named PcLFY. This gene has a large C-terminal region of high similarity to angiosperm FLO/LFY orthologs and shorter regions of local similarity. In contrast to angiosperms, conifers have two divergent genes resembling LFY. Gymnosperm FLO/LFY proteins constitute a separate clade, that can be divided into two divergent groups. Phylogenetic analysis of deduced protein sequences has shown that PcLFY belongs to the LFY-like clade....

A generalized nonlinear tempeature response function for some growth and developmental parameters in kiwifruit (Actinidia deliciosa (A. Chev.) C. F. Liang & A. R. Ferguson) Ciência Rural
Streck,Nereu Augusto.
Temperature is a major factor that affects metabolic processes in living organisms. Thermal time has been widely used to account for the effects of temperature on crop growth and development. However, the thermal time approach has been criticized because it assumes a linear relationship between the rate of crop growth or development and temperature. The response of the rate of crop growth and development to temperature is nonlinear. The objective of this study was to develop a generalized nonlinear temperature response function for some growth and developmental parameters in kiwifruit (Actinidia deliciosa (A. Chev.) C. F. Liang & A. R. Ferguson). The nonlinear function has three coefficients (the cardinal temperatures), which were 0ºC, 25ºC, and...

A Global Mitigation Hierarchy for Nature Conservation ArchiMer
Arlidge, William N. S.; Bull, Joseph W.; Addison, Prue F. E.; Burgass, Michael J.; Gianuca, Dimas; Gorham, Taylor M.; Jacob, Celine; Shumway, Nicole; Sinclair, Samuel P.; Watson, James E. M.; Wilcox, Chris; Milner-gulland, E. J..
Efforts to conserve biodiversity comprise a patchwork of international goals, national-level plans, and local interventions that, overall, are failing. We discuss the potential utility of applying the mitigation hierarchy, widely used during economic development activities, to all negative human impacts on biodiversity. Evaluating all biodiversity losses and gains through the mitigation hierarchy could help prioritize consideration of conservation goals and drive the empirical evaluation of conservation investments through the explicit consideration of counterfactual trends and ecosystem dynamics across scales. We explore the challenges in using this framework to achieve global conservation goals, including operationalization and monitoring and compliance,...

A HISTÓRICA CONCEPÇÃO DE DESENVOLVIMENTO FRENTE ÀS IDENTIDADES REGIONAIS: O CASO DO RINCÃO DOS MENDES NO MUNICÍPIO DE ROSÁRIO DO SUL/RS AgEcon
Rozalino, Luciano; Brito, Andreia Nunes Sa; Neumann, Pedro Selvino; Silveira, Paulo Roberto Cardoso da; Genro, Cicero Joao Malmann.
O presente artigo propõe uma reflexão sobre o enfoque convencional de desenvolvimento da região denominada de Metade Sul do Rio Grande do Sul, tomando como referência uma comunidade situada na APA do Ibirapuitã, no município de Rosário do Sul. As abordagens atuais, apoiadas em indicadores como PIB per capta, Valor Adicionado Fiscal e geração de postos de trabalho, consideram a região como pouco desenvolvida. Entre as estratégias utilizadas para reversão desse quadro destacam-se a expansão das modernas lavouras empresarias de arroz e soja e o fomento aos empreendimentos no ramo florestal. Assim, a pergunta central desse artigo é sobre a capacidade dessas estratégias em promover verdadeiramente o “desenvolvimento” da metade sul do RS. O estudo destaca os...

A simplified table for staging embryos of the pipid frog Pipa arrabali Anais da ABC (AABC)
ARAÚJO,OLÍVIA G.S.; HADDAD,CÉLIO F.B.; SILVA,HÉLIO R. DA; PUGENER,LOURDES A..
ABSTRACT Pipa is a Neotropical genus of frogs that dwell in freshwater environments. It includes four species that lack free-swimming larvae (P. aspera, P. arrabali, P. pipa, and P. snethlageae) and three with tadpoles (P. carvalhoi, P. myersi, and P. parva). Developmental tables such as the one proposed by Nieuwkoop and Faber might be useful for Pipa species with tadpoles. However, for the other Pipa species, to determine stages by this table or by any of the tables already prepared for frogs without tadpoles (e.g., Crinia nimbus, Eleutherodactylus coqui, and Oreobates barituensis) is impossible. By using embryonic, juvenile, and subadult specimens, we generated a staging table for P. arrabali, from the moment limb buds were first observed until birth,...

We applied an integrative framework to illuminate and discuss the complexities of exurbanization in Macon County, North Carolina. The case of Macon County, North Carolina, highlights the complexity involved in addressing issues of exurbanization in the Southern Appalachian region. Exurbanization, the process by which urban residents move into rural areas in search of unique natural amenities and idealized lifestyles, can often have a dramatic impact on the local economy, culture, and environment. Within Macon County, complex debates and tensions among multiple stakeholders struggle to address local residential development. How can better problem definition benefit rural communities in addressing exurbanization pressures and effects? We asserted that a key...

Adding value to local resources specifically tailored for developing São Paulo State’s vitiviniculture AgEcon
Verdi, Adriana Renata; Otani, Malimiria Norico; Fredo, Carlos Eduardo.
São Paulo state’s vitiviniculture ranks second in Brazil, being characterized by the production of table grapes and wines derived from American and hybrid varieties. Despite its economic, social, and environmental benefits, the state’s vitiviniculture has witnessed an increasing dependence on grapes produced in other states over the last decade. Besides adding to the cost of producing wine in São Paulo, grape imports from the state of Rio Grande do Sul compromises not only product quality, but also the process of creating an identity for the product. To give a new impetus to the production of grapes and wines in São Paulo, the State of São Paulo Research Foundation (FAPESP) developed a project called “Revitalizing São Paulo’s Vitivinicultural Chain,” a...

Adenosine as a signaling molecule in the retina: biochemical and developmental aspects Anais da ABC (AABC)
PAES-DE-CARVALHO,ROBERTO.
The nucleoside adenosine plays an important role as a neurotransmitter or neuromodulator in the central nervous system, including the retina. In the present paper we review compelling evidence showing that adenosine is a signaling molecule in the developing retina. In the chick retina, adenosine transporters are present since early stages of development before the appearance of adenosine A1 receptors modulating dopamine-dependent adenylate cyclase activity or A2 receptors that directly activate the enzyme. Experiments using retinal cell cultures revealed that adenosine is taken up by specific cell populations that when stimulated by depolarization or neurotransmitters such as dopamine or glutamate, release the nucleoside through calcium-dependent...

Adjustment of four growth models through Bayesian inference on weight and body nutrient depositions in laying quail R. Bras. Zootec.
Finco,Eline Maria; Marcato,Simara Márcia; Furlan,Antonio Claudio; Rossi,Robson Marcelo; Grieser,Daiane de Oliveira; Zancanela,Vittor; Oliveira,Taciana Maria Moraes de; Stanquevis,Caroline Espejo.
ABSTRACT An experiment was conducted to estimate the parameters of the Gompertz, Brody, Logistic, and Von Bertalanffy equations through Bayesian inference and evaluate the potential for growth in terms of weight and body composition of laying female quail (Coturnix coturnix japonica). The weights and body compositions of the birds were obtained weekly (1-119 days), allowing the adjustment of the four equations by Bayesian inference. The parameters mature weight (β1), integration constant (β2), maturity rate (β3), and their credibility intervals in four models on body weight and body components were properly estimated by Bayesian inference to describe the body growth in laying quail. The inflection point was determined by the 1st and 2nd derivatives of the...

African Aquaculture: A Regional Summary with Emphasis on Sub-Saharan Africa OceanDocs
Moehl, J.; Machena, C..
The African Region consists of 48 countries and five island nations, most of which are practising some form of aquaculture, often at a very low level. Over half the countries report producing less than 100 mt annually. The largest producer is Nigeria (17 700 mt) followed by Madagascar (5 100 mt) and Zambia (4 700 mt). The 1997 combined aquaculture production of the region was 40 300 mt. Aquaculture is estimated to be 95 percent small scale, with fish ponds integrated into the mosaic of agricultural activities. Mean yield is approximated as 500 kg/ha/yr, although the range is wide, from less than a hundred to more than 10 000 kg/ha/yr. A typical scenario would be a 300 m2 pond producing 15 kg a year relying on family labour and on-farm inputs. There is...

Aging gene pathway of microRNAs 156/157 and 172 is altered in juvenile and adult plants from in vitro propagated Prunus sp. Ciencia e Investigación Agraria
Bastías,Adriana; Almada,Rubén; Rojas,Pamela; Donoso,José Manuel; Hinrichsen,Patricio; Sagredo,Boris.
A. Bastías, R. Almada, P. Rojas, J.M. Donoso, P. Hinrichsen, and B. Sagredo. 2016. Aging gene pathway of microRNAs 156/157 and 172 is altered in juvenile and adult plants from in vitro propagated Prunus sp. Cien. Inv. Agr. 43(3):429-441. In vitro culture is a very popular technique to mass propagate valuable plant genotypes, including Prunus sp. cultivars. Plants that undergo tissue culture processes often change their morphology and behavior due to the "rejuvenation" caused by the plant growth regulators included in the medium. To evaluate the effects of rejuvenation by tissue culture in Prunus sp., the expression patterns of the aging gene pathway described in plant models, which include the highly conserved microRNA (miRNA or miR) 156/157 and 172...
