Toxicity and Binding Studies of Bacillus thuringiensis Cry1Ac, Cry1F, Cry1C, and Cry2A Proteins in the Soybean Pests Anticarsia gemmatalis and Chryso…

2017

ABSTRACT Anticarsia gemmatalis (velvetbean caterpillar) and Chrysodeixis includens (soybean looper, formerly named Pseudoplusia includens ) are two important defoliating insects of soybeans. Both lepidopteran pests are controlled mainly with synthetic insecticides. Alternative control strategies, such as biopesticides based on the Bacillus thuringiensis (Bt) toxins or transgenic plants expressing Bt toxins, can be used and are increasingly being adopted. Studies on the insect susceptibilities and modes of action of the different Bt toxins are crucial to determine management strategies to control the pests and to delay outbreaks of insect resistance. In the present study, the susceptibilitie…

Lifelong soya consumption in males does not increase lifespan but increases health span under a metabolic stress such as type 2 diabetes mellitus.

2021

Soya consumption can decrease oxidative stress in animal models. Moreover, phytoestrogens such as genistein, present in soya, can mimic some of the beneficial effects of estrogens and are devoid of significant side effects, such as cancer. In this study, we have performed a controlled lifelong study with male OF1 mice that consumed either a soya-free diet or a soya-rich diet. We show that, although we found an increase in the expression and activity of antioxidant enzymes in soya-consuming mice, it did not increase lifespan. We reasoned that the soya diet could not increase lifespan in a very healthy population, but perhaps it could extend health span in stressed animals such as type 2 diab…

If we eat soy, do we keep the beneficial effects of the Mediterranean diet?

2020

PurposeThis study aims to evaluate if soya consumption can compromise or positively influence the effects of the Mediterranean diet (MD).Design/methodology/approachA full literature review has been conducted as part of a proposal of a new point of view on the consumption of soya and its derivatives in areas where until a few decades ago this type of food did not exist at all.FindingsThere does not seem to be any contraindications for soy systematic use, therefore, excluding historical-geographical reasons, soya could be included in an MD without altering the benefits associated with it.Practical implicationsSoya is not advised as a typical food in the MD, but promoting its use could probabl…

Efecto del consumo de soja en la longevidad de ratones OF1 machos

2013

Encontrar buenos modelos de envejecimiento es un objetivo importante de la Gerontología. La diferencia de género en la longevidad, es decir, el hecho de que las hembras viven alrededor del 10% más que los machos en muchas especies, incluida la especie humana, ofrece una oportunidad única para estudiar los aspectos fundamentales del envejecimiento. En el contexto de la teoría mitocondrial de radicales libres en el envejecimiento, estudios realizados por nuestro grupo de investigación han encontrado que la producción de especies reactivas de oxígeno es aproximadamente el doble en los machos en comparación con las hembras (Borras et al., 2003). Así, dichas diferencias de longevidad entre macho…

Effects of Humic Substances and Soya Lecithin on the Aerobic Bioremediation of a Soil Historically Contaminated by Polycyclic Aromatic Hydrocarbons (…

2004

The high hydrophobicity of polycyclic aromatic hydrocarbons (PAHs) strongly reduces their bioavailability in aged contaminated soils, thus limiting their bioremediation. The biodegradation of PAHs in soils can be enhanced by employing surface-active agents. However, chemical surfactants are often recalcitrant and exert toxic effects in the amended soils. The effects of two biogenic materials as pollutant-mobilizing agents on the aerobic bioremediation of an aged-contaminated soil were investigated here. A soil historically contaminated by about 13 g kg(-1) of a large variety of PAHs, was amended with soya lecithin (SL) or humic substances (HS) at 1.5% w/w and incubated in aerobic solid-phas…

Determination of soyasaponins I and βg in raw and cooked legumes by solid phase extraction (SPE) coupled to liquid chromatography (LC)-mass spectrome…

2013

Legumes contain a rich variety of phytochemicals as soyasaponins, triterpenoidal glycosides that possess multiple health-promoting properties, such as lowering of cholesterol. In this work, the quantification of soyasaponins I and βg in 60 raw and cooked legumes by using a solid phase extraction (SPE) coupled to a liquid chromatography (LC)-mass spectrometry (MS) method was carried out. Results showed that lentils are a good source of soyasaponins, with a content of soyasaponin I that ranged from 636 to 735 mg kg(-1) and of soyasaponin βg from 672 to 1807 mg kg(-1). The cooking process produced a small loss of soyasaponins in water, that is, 4.8-8.7%, and partially converted soyasaponin βg …

Effect of soyasaponin I against cytotoxicity and oxidative stress induced by alternariol in Caco-2 cells

Sustainable development for soya production based on the field research carried out at the Variety Assessment Experimental Station of Głubczyce in th…

2018

The aim of this research was to determine the impact of various nitrogen fertilization systems in soya cultivation on quality and quantity of crop, as well as to examine the economic aspects of sustainable farming. The study was based on research carried out in the Variety Assessment Research Station of Głubczyce (years: 2015-2017). The soybean, protein and fat of four soya varieties (Glycine max (L.)Merrill) non-GMO (Augusta, Mavka, Aligator, Lissabon) were compared, using varying doses of N/ha (0, 30 and 60 kg). The cost effectiveness of the various fertilization doses was also determined. The soybean yields of the different soya varieties differed significantly, which indicates the exist…
