Common methods of managing dairy manure are directly applying it to the farm field as a fertilizer. For direct application without any type of treatment, the majority of nutrients in the manure run off to the local river and lake during precipitation periods. The algae bloom is one of the environmental outcomes due to eutrophication of the lakes, which may jeopardize the quality of drinking water. In this study, superheated steam drying (SSD) technology is investigated as an alternative manure management method...

We assess here, through an experimental simulation using lead nitrate, the response to lead deposition of three common Mediterranean bryophyte species in the family Pottiaceae. Five concentrations of lead nitrate (from 0 to 10(-3) M) were sprayed for 4 months on plants belonging to Tortula muralis (reported as toxitolerant), Syntrichia ruralis (medium-tolerant), and Tortula subulata (less tolerant). The three species showed a remarkably high tolerance to lead nitrate, with a low incidence of damage even at concentrations as high as 10(-4) M...

Incorporation of genetically modified crops in the cropping system raises the need for studying the effect of these crops on the soil ecosystem. The current study aimed to compare the effect of Bacillus thuringiensis (Bt)- and non-Bt-cotton (Gossypium hirsutum L.) genotypes on rhizosphere properties under fertilized and unfertilized soil conditions. One non-Bt-cotton (IUB 75) and four Bt-cotton varieties (IUB-222, MM-58, IUB-13, FH-142) were sown in a Randomized Complete Block Design (RCBD) in a factorial fashion with three replications under unfertilized (T1) and fertilized (T2 at NPK 310-170-110 kg ha(-1)) soil conditions...

Nonalcoholic fatty liver disease (NAFLD) spans steatosis through nonalcoholic steatohepatis, cirrhosis, and hepatocellular carcinoma (HCC) associated with striking systemic features and excess cardiovascular and liver-related mortality. The pathogenesis of NAFLD is complex and multifactorial. Endocrine derangements are closely linked with dysmetabolic traits. For example, in animal and human studies, female sex is protected from dysmetabolism thanks to young individuals' ability to partition fatty acids towards ketone body production rather than very low density lipoprotein (VLDL)-triacylglycerol, and to sex-specific browning of white adipose tissue...

Parthenogenetically activated oocytes cannot develop to term in mammals due to lack of paternal gene expression. Disruption of imprinted gene expression and DNA methylation status in parthenogenetic fetuses has been reported in mice and pigs, but not in rabbits. In this study, the genomic imprinting status of the paternally expressed genes Neuronatin (NNAT), Nucleosome assembly protein 1-like 5 (NAP1L5), and Makorin ring finger protein 3 (MKRN3) was compared between rabbit parthenogenetic (PA) and normally fertilized fetuses (Con) using quantitative real-time PCR (qRT-PCR) and bisulfite sequencing PCR (BSP)...

Sirtuins are nicotinamide adenine dinucleotide dependent class III histone deacetylase proteins that play a crucial role in several cellular processes, including DNA repair, apoptosis, and lifespan. Previous studies have shown that sirtuin inhibition leads to embryonic developmental arrest and oxidative stress in porcine and murine. However, sirtuin-mediated mechanisms have not been examined in porcine preimplantation blastocysts. We therefore investigated the relationship between sirtuins and autophagy. Embryos were cultured with 100 μM sirtinol (SIRT1/2 inhibitor) in NCSU-23 media after in vitro fertilization...

This study was aimed at determining whether an in vivo subcutaneous exposure to n-butylparaben (n-ButP) during one complete spermatogenic cycle could be harmful to the reproductive system of young male rats. Animals were subcutaneously given 0, 150, 300 and 600 mg/kg/day of n-ButP with vehicle (peanut oil). Body and organ weights, n-ButP excretion, biochemical parameters, sperm and spermatid count, sperm motility, viability, maturity and morphology were examined. Results showed that after a completed spermatogenic cycle, although n-ButP did not induce dose-related changes in the different biochemical parameters, a significant decrease of triacylglicerides (TAG) -due to the vehicle-was found...

Zinc (Zn) deficiency in human populations depending on cereals as a main source of Zn is a global malnutrition problem. In this field study, we investigated the potential of green manure application to increase soil Zn availability and wheat grain Zn concentrations (biofortification) on a Luvisol with different long-term fertilizer management. We also studied cadmium (Cd), as wheat is a major contributor of this undesired non-essential element to human diets. Clover (Trifolium alexandrinum L.), mustard (Sinapis alba L...

Application of assisted reproductive technology in camelidea, such as artificial insemination (AI) and embryo transfer, has been slow in comparison to that for other livestock species. In Egypt, there are few attempts to establish in vitro maturation (IVM) and fertilization (IVF) techniques in dromedary camel. The present study was carried out to produce Sudanese camel embryos using in vitro matured oocytes and epididymal spermatozoa. Dromedary camel ovaries were collected from abattoirs and then, the oocytes were aspirated from all the visible follicles on the ovarian surface (~2-8 mm in a diameter)...

Coating fertilizer particles with thin films is a possibility to control the fertilizer release rates. It is observed that novel urea crosslinked starch-lignin composite thin films, prepared by solution casting, swell on coming into contact with water due to increase in volume by water uptake diffusion. The effect of lignin content, varied from 0% to 20% in steps of 5% and three different temperatures (25°C, 35°C and 45°C) on swelling of the film was investigated. By gravimetric analysis, the equilibrium water uptake and diffusion coefficient decrease with lignin content indicating that the addition of lignin increases the hydrophobicity of the films...

Foliar application of micronutrients (e.g. Fe(3+) ) onto plants over an extended time is challenging and often not possible due to insufficient rainfastness. Smart delivery systems which enable micronutrient release over several weeks would offer innovative and sustainable options to improve plant health and food production. Herein, we report a novel foliar fertilizer delivery system based on functional pH-responsive biohybrid microgels that have orthogonal functionality as carriers of micronutrients and employ peptides (termed anchor peptides) as foliar adhesion promoters...
