Macroendoscopical and histopathological aspects in Helicobacter pylori gastroenteritis in dogs– case report

In current veterinary medical practice, more clinical and imaging investigations are needed to fully assess a patient with digestive symptoms. In this case, the anamnesis and patient history are the starting points in staging a diagnosis. Questions with uncertain answers lead to laboratory tests – blood count and blood biochemistry. The etiologic diversity in digestive pathologies implies these blood tests to exclude some of the diseases. X-ray and ultrasound examinations are the next steps to follow; these are diagnosis methods that precede the endoscopic examination. After the macroendoscopic evaluation of the digestive tract, biopsy samples must be taken for the Helicobacter pylori quick test (Figure 1). Histological examination of the biopsy samples taken from canine patients, which were positive for Helicobacter pylori, can reveal another lesions in the digestive tract; in this moment a treatment can be initiated to reduce or even to abolish the simptomatology

Studies on the effect of the number of farrowed sows in heat per box

This scientific paper has as main objective the way how the type of box influences the number of farrowed sow. The number of sows of the Landrace breed that are in heat after weaning the piglets, tidmatter the duration of lactation or the number of boxes they are located in, is considerably larger than that of oestrus sows during lactation. Animal density in the box obviously influenced the appearance of heat, the largest share being in sows located by seven, i.e. 96.25%, and the lowest one, 59.68%, was in the sows located in larger boxes (32 capita). Achieving high performances of production and reproduction in raising swine greatly depends on the way animals are taken care of and exploited, i.e. the shedding system, the exploitation technology, the building material of the sheds, inside equipment, and degree of mechanisation. In sows with a 35-day lactation, the share of post partum heat occurrence had close values (though somewhat smaller), oscillating between 19.52% and 23.33%

Experimental study on viscosity and isobaric heat capacity of PEG 400 enhanced with TiO2 nanoparticles

In the last years, a lot of research is committed to developing new heat transfer fluids for medium to high temperatures applications. This experimental analysis is dedicated to a less studied fluid, PEG 400 enhanced with titanium oxide nanoparticles, and started with suspensions manufacturing, morphology analysis and a strong discussion on viscosity, rheological behavior and isobaric heat capacity. Precisely, five suspensions of up to 2.5 %wt. TiO2 were analyzed through the entire experimental in terms of their behavior at ambient temperature and heating. Plus, viscosity was checked for possible hysteresis and the experimental revealed that this is almost absent for these nanocolloids, which is favorable for heat transfer applications, especially in heat exchange. The rheological tests revealed a non-Newtonian comportment for all of the samples, comportment that is more obvious when nanoparticles concentration increases. In terms of viscosity outputs, a normal fluidic behavior was noticed at heating, while the viscosity upsurges between 8 and 36 %, depending on nanoparticle concentration. Isobaric heat capacity tests demonstrated a decrease of up to 6.3 % for higher loaded nanocolloids and a relatively small variation with temperature, which is, somehow, in line with state of the art. As a conclusion, it may affirm that nanocolloids based on PEG 400 and oxides can be a good alternative for heat exchange applications
