Sensory quality of meat from lambs fed on different diets

The whole seed of sweet lupin var. Multitalia with a protein content higher than 35% and a low content in alkaloids constitutes a good protein source alternative to soybean meal, today deriving for more than 60% from OGM (Genetically Modified Organisms) cultivation. Moreover, the poor national production and the cost of feeds for animals forces the livestock compartment to utilize alternative biomasses the availability of which highly depends on from the environment and the season

evaluation of animal welfare and milk production of goat fed on diet containing hydroponically germinating seeds

Hydroponic fodder is a particularly nutritious feed, rich in protein and vitamins such as ß-carotene, trace elements and enzymes. It may also offer the advantage of a continuous availability. A pilot plant for hydroponically production of germinating seeds was built in an area of the same farm where the trial took place. Three homogeneous groups of 30 Jonica breed goats in lactation (4th-5th parity) were used to evaluate the effects of two different levels of partial dietary substitution with hydroponically germinating (h.g.) oat on plasma levels of cortisol and milk production. Germinated oat was used after 7 days of hydroponic growth. Control group (T) received only feed (fodder and oat integrated with complement feed). The other 2 groups were fed on diet containing different levels (1,5Kg - group A; 3Kg - group B) of hydroponically germinating oat. Goats showed a small interest in fresh feed during the trial period. The integration with hydroponically germinating oat in partial substitution of the traditional feed in the diet of goat did not significantly affect biochemical and haematological parameters

A Giant Gastric Hyperplastic Polyp in Non-Familial Juvenile Polyposis of the Stomach: A Case Report

Juvenile Polyposis Syndrome (JPS) is a rare genetic disorder characterized by juvenile polyps of the gastrointestinal tract, which may also occur in people with no family history of the disorder. It usually involves the colorectum and more rarely the stomach. Juvenile polyps can vary in size from a few millimeters to over 5cm, and, although they have microscopically specific characteristics, the distinction between them and inflammatory polyps is often difficult. Here we present a case of 41 year old woman with no family history of polyposis who underwent esophagogastroduodenoscopy (EGDS) because of anemia that showed a huge and extensive gastric lesion (10 cm in diameter) and other small polyps scattered through the stomach lumen and duodenum. The histology report revealed the big lesion and the polyps were hyperplastic polyps with infiltration of inflammatory cells. Due to clinical history and EGDS findings, the patient underwent a pylorus-preserving gastrectomy, and to define a final diagnosis genetic test was performed and showed mutation in the SMAD4 gene. Thus non-familial juvenile polyposis of the stomach was diagnosed. An original feature of the current case was the rare finding of huge hyperplastic gastric polyp in a woman with rare non-familial JPS of the stomach. In fact, to our best knowledge this is the first report describing a so giant gastric polyp in JPS of the stomach in an adult woman. Furthermore, our report suggests that it is noteworthy to consider JP as differential diagnosis in patients with non-familial polyposis, anemia or hypoproteinemia and polyps histologically diagnosed as hyperplastic and performing genetic testing for confirming diagnosis and helping in the timely and appropriate management

Bithiazole Inhibitors of Phosphatidylinositol 4-Kinase (PI4KIIIβ) as Broad-Spectrum Antivirals Blocking the Replication of SARS-CoV-2, Zika Virus, and Human Rhinoviruses

Over half a century since the description of the first antiviral drug, “old” re-emerging viruses and “new” emerging viruses still represent a serious threat to global health. Their high mutation rate and rapid selection of resistance toward common antiviral drugs, together with the increasing number of co-infections, make the war against viruses quite challenging. Herein we report a host-targeted approach, based on the inhibition of the lipid kinase PI4KIIIβ, as a promising strategy for inhibiting the replication of multiple viruses hijacking this protein. We show that bithiazole inhibitors of PI4KIIIβ block the replication of human rhinoviruses (hRV), Zika virus (ZIKV) and SARS-CoV-2 at low micromolar and sub-micromolar concentrations. However, while the anti-hRV/ZIKV activity can be directly linked to PI4KIIIβ inhibition, the role of PI4KIIIβ in SARS-CoV-2 entry/replication is debated

Particles-vortex interactions and flow visualization in He4

Recent experiments have demonstrated a remarkable progress in implementing and use of the Particle Image Velocimetry (PIV) and particle tracking techniques for the study of turbulence in He4. However, an interpretation of the experimental data in the superfluid phase requires understanding how the motion of tracer particles is affected by the two components, the viscous normal fluid and the inviscid superfluid. Of a particular importance is the problem of particle interactions with quantized vortex lines which may not only strongly affect the particle motion, but, under certain conditions, may even trap particles on quantized vortex cores. The article reviews recent theoretical, numerical, and experimental results in this rapidly developing area of research, putting critically together recent results, and solving apparent inconsistencies. Also discussed is a closely related technique of detection of quantized vortices negative ion bubbles in He4.Comment: To appear in the J Low Temperature Physic
