Raw ingredients of pet food are often contaminated with mycotoxins. This is a serious health problem to pets and causes emotional and economical stress to the pet owners. The aim of this study was to determine the immunotoxicity of the most common mycotoxins (aflatoxin, fumonisin, ochratoxin A and zearalenone) by examining 20 samples of extruded dry dog food found on the South African market [10 samples from standard grocery store lines (SB), 10 from premium veterinarian lines (PB)]. Pelleted dog food was subjected to extraction protocols optimized for the above mentioned mycotoxins...

Despite the increasing understanding of the magnitude and drivers of carbon gas emissions from inland waters, the relevance of water fluctuation and associated drying on their dynamics is rarely addressed. Here, we quantified CO 2 and CH 4 fluxes from a set of temporary ponds across seasons. The ponds were in all occasion net CO 2 emitters irrespective of the presence or absence of water. While the CO 2 fluxes were in the upper range of emissions for freshwater lentic systems, CH 4 fluxes were mostly undetectable...

As in many other cities, urbanization coupled with population growth worsens the water supply problem of Addis Ababa, Ethiopia, with a water supply deficit of 41% in 2016. To investigate the potential contribution of rooftop rainwater harvesting (RWH) from large public institutions, 320 such institutions were selected and grouped into 11 categories, from which 25-30% representative 588 rooftops were digitalized and the potential RWH volume computed based on a ten-year rainfall dataset. When comparing the resulting RWH potential with the water consumption, up to 2...

The equilibrium outcomes of ball mill grinding can dramatically change as a function of even tiny variations in the experimental conditions such as the presence of very small amounts of added solvent. To reproducibly and accurately capture this sensitivity, the experimentalist needs to carefully consider every single factor that can affect the ball mill grinding reaction under investigation, from ensuring the grinding jars are clean and dry before use, to accurately adding the stoichiometry of the starting materials, to validating that the delivery of solvent volume is accurate, to ensuring that the interaction between the solvent and the powder is well understood and, if necessary, a specific soaking time is added to the procedure...

Wharton`s jelly-derived mesenchymal stem cells (WJ-MSCs), have a high proliferation valency and they do not produce teratogen or carcinogen after subsequent transplantation. They are known as regenerative medicine. Thus more research is needed on the isolation and characterization of mesenchymal stem cells. In this experimental study, we obtained Wharton's jelly tissues from mothers during normal vaginal delivery, after obtaining their informed consent. Mesenchymal stem cells were isolated from cultured Wharton`s jelly, cultured, and were then examined for their proliferation, immunophenotypes, and differentiation capacities...

Lake Tanganyika, an African Great Lake, is a complex tropical ecosystem that has been subjected to extreme climate-related changes in the last century, including seasonal changes in temperature and rainfall, decreased overall annual rainfall, and greater frequency of rainstorms. Atmospheric nitrogen (N) is an important component of the lake's N loading, but how long-term and seasonal changes in precipitation affect this loading still needs clarification. This study aimed to improve our understanding of the seasonal features of N deposition in the lake, by monitoring atmospheric N deposition concentrations and fluxes from March 2013 to February 2014...

Dry eye has become the most common ophthalmic disease besides ametropia. As a chronic ophthalmic disease, dry eye, which in serious cases might even lead to blindness, not only affects the life quality of the patient, but also poses adverse impact on social productivity and work efficiency, and moreover influences the development of society and economy. The incidence of dry eye has been rising in recent years because of the widespread use of video terminals, which poses greater challenges for us. Therefore, we put forward the concept of chronic disease management for dry eye in the hope of drawing extensive attention and planning ahead of time, so as to meet the needs of dry eye patients in China...

Date syrup is rich in fermentable sugars and may be used as a substrate for different microbial fermentations, including lactic acid fermentation processes. The beneficial effects of ultrasounds (US) on bioprocesses have been reported for several microorganisms, due to the enhancement of cell growth, as well as improvements in yields and productivities. Therefore, US treatments (30 kHz, 100 W, 10-30 min) were applied to two lactobacilli (Lactobacillus helveticus PTCC 1332 and Lactobacillus acidophilus PTCC 1643), during fermentation using date syrup as substrate...

Biochar amendment to soil is predicted globally as a means to enhance soil health. Alongside the beneficial result on soil nutrient availability and retention, biochar is presumed to increase soil macro / microbiota composition and improve plant growth. However, evidence for such an effect remains elusive in many tropical agricultural soils. The influence of biochar aged in soil was assessed on soil microbiota, macrobiota (Eudrilus eugeniae), seedling emergence and early plant growth of Oryza sativa and Solanum lycopersicum in tropical agricultural soil, over a 90 d biochar-soil contact time...

Layered treatments of natural stones based on dispersions of experimental nano-TiO2 and commercial TEOS, showing photocatalytic and self-cleaning properties have been set-up and tested. To enhance nano-TiO2 efficacy, a surface pre-treatment with tetraethyl orthosilicate has been proposed to avoid the penetration of NPs into the crystalline porous substrates and to improve their adhesion to the stone. Two treatment applications - wet-on-wet and wet-on-dry -have been compared, showing different results. A strong interaction Si-O-Ti has proved to be the key factor for the successful treatment, leaving the bandgap and relevant properties of nano-TiO2 unaltered...

Indian gaur (Bos gaurus) is one of nine species of wild oxen found in the world. They are largely confined to evergreen, semi-evergreen, and moist deciduous forests, but also occur in dry deciduous forest areas at the periphery of their range. According to the IUCN Red List ( 2017 ), the estimated population of gaur in India is between 15,000 and 35,000 individuals, and probably due to this, despite the gaur's vast range of distribution, they are listed as a vulnerable species by IUCN and listed as schedule-I of the Indian Wildlife Protection Act ( 1972 ) as well as in appendix-I in CITES ( 2003 )...
