The researches regarding the threshing process made by tangential threshing system of conventional harvester combines had as result the obtaining of mathematical models, based on experimental data, expressed through functions that partially define this process. Moreover, for the threshing systems with multiple rotors, the mathematical modelling of threshing process made by them is more difficult. This paper presents a mathematical model of the threshing process made by the threshing system with multiple rotors of the Romanian combine C110ATM. The mathematical model was based on the experimental data gathered by INMA Bucharest in 2001.

The virus that causes chickenpox--varicella zoster virus (VZV)--possesses a protein that could enhance its ability to hijack white blood cells and spread throughout the body, according to new research published in PLOS Pathogens. The findings, presented by Víctor González-Motos of Hannover Medical School, Germany, and colleagues, may provide new insight into the poorly understood mechanism by which VZV spreads after initial infection in the respiratory tract. VZV causes chickenpox in children and can reactivate later in life to cause shingles. After infecting the respiratory tract, the virus hijacks the immune system's white blood cells, using them to spread in the body--including to the skin to cause chickenpox. To better understand this process, the researchers investigated whether VZV influences the function of chemokines, small immune system proteins that attract white blood cells to sites of infection and guide their movement within the body. The scientists focused on a VZV protein known as glycoprotein C, since previous research suggested it may play an important role in the infection cycle. In the lab, they performed chemotaxis experiments and found that the addition of glycoprotein C enhances the ability of chemokines to attract white blood cells, including white blood cells from the tonsils, which are a major target of VZV during initial infection. Further experiments uncovered the molecular details of the interaction between glycoprotein C and chemokines. The researchers also showed that VZV viral particles that had been genetically engineered to remove glycoprotein C had a reduced ability to enhance chemokine attraction of white blood cells, indicating the importance of glycoprotein C for this process. Overall, these results suggest that glycoprotein C may interact with chemokines to attract more white blood cells to the site of VZV infection, where the virus can hijack the white blood cells to spread to other parts of the body. Further research is needed to investigate whether this hypothesis holds up in human tissue.

The urine of pregnant women could be used to help identify lifestyle interventions that help maintain a healthy birth weight for their baby, according to new research published in BMC Medicine. Abnormal fetal growth and birth weight are well-established risk factors for chronic diseases later in life, including the development of type-2 diabetes and obesity. Dr Mireille Toledano, co-lead author of the research from the School of Public Health at Imperial College London, said: "We used a technique called NMR spectroscopy to identify, for the first time, a panel of 10 urinary metabolites in the 3rd trimester of pregnancy that were associated with greater fetal growth and increased birth weight. These metabolites included steroid hormones and important biological building blocks called branched-chain amino acids (BCAAs)." BCAAs are essential nutrients that are vital during pregnancy as an energy source for the growing fetus. In this study, changes in BCAAs and other metabolites detected in the urine were able to explain 12% of the variation seen in birth weight, independent of other known predictors such as parent's own weight and maternal smoking or alcohol intake. Dr Muireann Coen, co-lead author from the Department of Surgery and Cancer at Imperial College London, added: "We found that a 50% increase in the mother's level of individual BCAAs equated to a 1-2.4% increase in birth weight, or 5-11 grams. When we made comparisons with the lifestyle and environmental exposures of the women in our study we found that the variability between BCAA profiles of individual mothers could be partially explained by levels of physical activity, vitamin D, coffee consumption and smoking exposure, suggesting them to be potential areas of intervention to promote a healthy birth weight." The research team from Spain at ISGlobal, collected urine samples and lifestyle questionnaire data from over 800 pregnant women, aged 28-33 years old, from two locations in Spain (Gipuzkoa and Sabadell), making it the most comprehensive study of urinary metabolites and fetal weight outcomes to date. The two locations in Spain differed in socio-demographic factors, with women in Gipuzkoa reported to be more educated, from a higher social class and generally healthier than women from Sabadell. This distinction allowed for useful comparisons to be made between women from different backgrounds and different geographical location. Although the researchers found an association between several lifestyle factors and the metabolomic signature detected in the mother's urine, it is not clear from this study if one is the cause of the other, or if any specific lifestyle factor is associated with an individual metabolite. In observational studies like this it is not possible to rule out other factors and an experimental trial would be needed to test cause and effect. This proof-of principle study highlights the value metabolic profiling of pregnant women could have on personalizing pregnancy plans to improve fetal growth outcomes.

Researchers from the University of Burgos (Spain) have developed a fluorescent polymer that lights up in contact with mercury that may be present in fish. High levels of the metal were detected in samples of swordfish and tuna. According to the conclusions of another Spanish study, mercury exposure is linked to reduced foetal and placental growth in pregnant women. The presence of the toxic metal mercury in the environment comes from natural sources, however, in the last decades industrial waste has caused an increase in concentrations of the metal in some areas of the sea. In the food chain, mercury can be diluted either in organic form as methylmercury (MeHg+) or as an inorganic salt, the cation Hg2+. Now, researchers from the University of Burgos have created a fluorescent polymer, JG25, which can detect the presence of these two forms of mercury in fish samples. The development is published in the journal Chemical Communications. "The polymer remains in contact with samples extracted directly from the fish for around 20 minutes. Then, while is being irradiated with ultraviolet light, it emits a bluish light, which varies in intensity proportionally to the quantity of methylmercury and inorganic mercury present in the fish," explains Tomás Torroba, lead author of the paper. A portable polymer probe, which can be used in situ, was used to apply the technique to 2-gram samples from a range of fish species. The qualitative relationship between the mercury levels in fish and the increased fluorescence was verified using chemical analysis (called ICP-Mass). The research showed that the larger is the fish the higher are the levels of mercury: between 1.0 and 2.0 parts per million for swordfish, tuna and dogfish, around 0.5 ppm in conger eels and 0.2 ppm in panga. No mercury was found in farmed salmon. These are large fish and at the top of the food chain, but the metal is not present in captivity due to the lack of an industrial or natural source. The toxicity of fish depends on the amount mercury found in the fish presented in the diet. According to the recommendations of the European Food Safety Authority (EFSA), the tolerable weekly intake of methylmercury should be no more than one serving containing amounts over 1.6 μg/kg (micrograms per kilogram of fish) or 4 μg/kg for inorganic mercury (this amount is close to the one detected in the study). However, the current trend for this limit is to be lowered. For example, the United States food safety agency, the FDA, goes beyond this and recommends consuming no more than one portion per week of fish containing concentrations over 1 μg/kg, a tendency other countries are likely to follow. "Contamination of above 0.5 ppm in a food is already thought to be a considerable level," Torroba explains. "Several of the fresh tuna and swordfish samples we analysed exceed and even double this amount. This is why experts recommend that pregnant women reduce their weekly intake of certain types of fish, such as swordfish, due to possible risks to the foetus." In this context, a study led by researchers from the Foundation for the Promotion of Health and Biomedical Research of the Community of Valencia (FISABIO, for its Spanish abbreviation) and the Spanish Consortium for Research on Epidemiology and Public Health (CIBERESP, for its Spanish abbreviation) has shown that there is an association between prenatal mercury exposure and reduced placenta size and foetal growth. The study, carried out within the Environment and Childhood (INMA, for its Spanish initials) mother-child cohort project, aimed to evaluate this link using data on 1,869 newborns from different regions of Spain (Valencia, Sabadell, Asturias and Guipúzcoa). One of the largest studies carried out to date in order to determine mercury levels in umbilical cord blood samples and its association with different reproductive effects: measurements of foetal development (weight, height and head circumference at birth), placental weight, duration of pregnancy and risk of premature birth. The findings, published in the journal Environmental Research, show a relatively high average mercury concentration in umbilical cord blood (8.2 micrograms per litre), with a 24% of samples exceeding the WHO's provisional tolerable weekly intake equivalent. "A double in the cord blood mercury concentrations (e.g. a change in the concentration from 8 to 16 micrograms per litre) is associated to a 7.7 gram reduction in the weight of the placenta and also shows a pattern of negative association with the newborn's head circumference," explain Mario Murcia and Ferran Ballester, co-authors of the study. "However no relation was found with other parameters, such as duration of pregnancy." The results of the INMA project suggest that prenatal mercury exposure may, therefore, be affecting the development of the placenta and foetal growth. Although the magnitude of these potential effects is small, reduced placental weight has been linked to the risk of high blood pressure in adulthood. Head circumference, in turn, has been associated with subsequent cognitive development. Despite preventive and surveillance measures are been considered for foods, due to the positive effects on health that are also linked to consuming fish, the researchers urge for public health efforts in order to reduce human mercury emissions.
