Efeito do tamanho do folículo na maturação nuclear e citoplasmática de ovócitos de fêmeas zebuínas

Este estudo avaliou o efeito do tamanho do folículo na capacidade dos ovócitos de sofrerem maturação nuclear e citoplasmática. Ovários de vacas Nelore (Bos indicus) foram coletados logo após o abate, e os complexos cúmulus-ovócitos foram aspirados de folículos de diferentes categorias, e classificados de acordo com seus diâmetros em: 1-2 mm, 3-5 mm, 6-8 mm e > ou = 9 mm. A medida do diâmetro e a fixação dos ovócitos para avaliação do estádio nuclear antes da maturação foram feitas logo após a aspiração. Ovócitos morfologicamente viáveis foram maturados, fecundados e cultivados in vitro. Os ovócitos obtidos de folículos de 1-2 mm apresentaram menor diâmetro (P<0,01) do que os dos demais grupos. Antes da maturação, 89,8%, 90,1%, 85,7% e 100% dos ovócitos provenientes de folículos de 1-2, 3-5, 6-8 e > ou = 9 mm de diâmetro, respectivamente, apresentavam vesícula germinativa. O tamanho do folículo não influenciou (P<0,05) a taxa de maturação nuclear. A porcentagem de ovócitos que chegaram a metáfase II foi de 88,8%, 87,8%, 92,9% e 100% no que se refere aos ovócitos de folículos de 1-2, 3-5, 6-8 e > ou = 9 mm, respectivamente. As taxas de penetração e clivagem foram semelhantes (P>0,05) nos grupos de 1-2 mm (93,4% e 81,9%), 3-5 mm (90,7% e 79,6%), 6-8 mm (91,3% e 77,8%) e > ou = 9 mm (92,0% e 78,3%). Da mesma forma, não houve diferenças (P>0,05) entre as categorias de folículos no que se refere às taxas de polispermia, descondensação da cabeça do espermatozóide e formação de pro-núcleos. Os resultados deste estudo demonstram que na espécie B. indicus, folículos com diâmetro de 1 mm até > ou = 9 mm não influenciaram a capacidade dos ovócitos de reiniciar e completar a meiose e de clivar após maturação e fecundação in vitro.

Controle da lagarta-da-soja com aplicações de seu vírus de poliedrose nuclear por vias aérea e terrestre

De 1983 a 1988 foram conduzidos, na região de Dourados, MS, seis experimentos e três campos-piloto, objetivando controlar a lagarta Anticarsia gemmatalis Hübner, 1818, com aplicações aérea e terrestre de seu vírus de poliedrose nuclear (VPN Ag). Cem lagartas equivalentes (LE) de VPN Ag associadas a óleo de soja, melaço de cana-de-açúcar e água, foram aplicadas com avião agrícola equipado com Micronair. Os preparados oleosos (5,5 e 5 L ha-1) e com melaço (10 L ha-1) controlaram 75-89% e 79-96% das lagartas, respectivamente. A suspensão aquosa de 3 L ha-1 foi ineficaz, porém as de 15, 20 e 25 L ha-1 controlaram de 81% a 90% das lagartas. Cinqüenta LE, aplicadas com avião agrícola (3 L ha-1) ou atomizador (15 L ha-1), foram ineficientes. Aplicações da mesma dose com pulverizador de barra (134 e 150 L ha-1) proporcionaram controle de 87% e 90%, respectivamente, e com avião (15, 20 e 25 L ha-1), entre 93% e 98%. Aplicações aéreas de 50 LE com óleo de soja (5 L ha-1) ou melaço (10 L ha-1) foram eficientes (86-88% e 99%, respectivamente). Aplicações aéreas de suspensões aquosas e formulado oleoso, em campos-piloto, confirmaram os resultados experimentais.

An Evaluation of the Troxler 3241-B Nuclear Asphalt Gauge, MLR-85-11, 1986

The Troxler 3241-B Asphalt Content Gauge is intended for rapidly determining the bitumen content of bituminous paving mixtures. A 300 Millicurie Americuium 241: Beryllium source emitts neutrons which are affected by the hydrogen in the mix. The affected neutrons are detected by Helium 3 detectors, counted and computed into a percentage bitumen of the asphalt mix. The current methods of determining the bitumen content of bituminous paving mixtures requires the use of potentially hazardous chemicals and several hours of testing time. When extracted aggregates are not needed, determination of the bitumen content of a paving mixture by the nuclear method may be easier, quicker and potentially safer. The objective of the project is to study the accuracy of the Troxler 3241-B Nuclear Asphalt Content Gauge in measuring the asphalt cement (AC) content of asphalt concrete mixtures produced with different asphalt cements and different aggregates.

Evaluation of Carbide Waste Lime for Soil Stabilization, Progress Report, HR-111

A lime by-product from the manufacture of acetylene from calcium carbide will be commercially available in Iowa. Since the cost of carbide waste lime f.o.b. source is only about half that of ordinary commercial lime, this material was investigated for potential uses in soil stabilization. The by-product lime is calcium hydroxide in a water slurry with approximately 40% solid concentration. Its effectiveness at stabilizing soils was checked by comparing with commercial high-calcium and dolomitic monohydrate varieties of lime. This was done by soil strength and plasticity tests in addition to studies of the reaction products by X-ray diffraction and chemical methods.

Targeting receptor activator of nuclear factor-kappa B as a new therapy for bone metastasis in non-small cell lung cancer.

PURPOSE OF REVIEW: The review aims at comprehensively discussing our current knowledge on bone metastases incidence in non-small cell lung cancer (NSCLC), their related complications as well as clinical impact in patients suffering from advanced disease. RECENT FINDINGS: After evoking the use of zoledronic acid as the established standard of care until recently, the new class of drugs available to prevent skeletal related events and targeting receptor activator of nuclear factor-kappa B (RANK) will be emphasized, reporting on denosumab clinical trials, a RANK-ligand (RANKL) targeting monoclonal antibody. Biological hypothesis regarding their mechanisms of action as well a potential direct impact on tumor cells are described according to the most recent laboratory as well as hypothesis-generating clinical data. SUMMARY: Targeting the RANK pathway is an efficient way to prevent complications of bone metastases in NSCLC. Interesting additional direct effects on tumor biology and evolution are being analyzed and prospectively assessed in clinical trials.

Estrogen-dependent in vitro transcription from the vitellogenin promoter in liver nuclear extracts.

One approach to analyzing the molecular mechanisms of gene expression in vivo is to reconstitute these events in cell-free systems in vitro. Although there is some evidence for tissue-specific transcription in vitro, transcriptionally active extracts that mimic a steroid hormone-dependent enhancement of transcription have not been described. In the study reported here, nuclear extracts of liver from the frog Xenopus laevis were capable of estrogen-dependent induction of a homologous vitellogenin promoter that contained the estrogen-responsive element.

Peroxisome proliferator-activated receptors: a nuclear receptor signaling pathway in lipid physiology.

Peroxisome proliferator-activated receptors (PPARs) are lipid-activated transcription factors that belong to the steroid/thyroid/retinoic acid receptor superfamily. All their characterized target genes encode proteins that participate in lipid homeostasis. The recent finding that antidiabetic thiazolidinediones and adipogenic prostanoids are ligands of one of the PPARs reveals a novel signaling pathway that directly links these compounds to processes involved in glucose homeostasis and lipid metabolism including adipocyte differentiation. A detailed understanding of this pathway could designate PPARs as targets for the development of novel efficient treatments for several metabolic disorders.
