Abstract Background Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) continues to be a major economic issue for the swine industry worldwide, not only due acute outbreaks but also endemic infections. PRRS disease severity consequently financial losses can vary greatly between endemically infected farms estimation of damage is challenging. This study aimed assess effect in systematic way at individual farm-level herds, using cost simulation tool. In total 21 German sow herds with...

Human atopic asthma is a complex heritable inflammatory disorder of the airways associated with clinical signs allergic inflammation and airway hyperresponsiveness. Recent studies demonstrate that degree responsiveness strongly interleukin (IL)-9 expression in murine lung. To investigate contribution IL-9 to hyperresponsiveness, explore directly its relationship inflammation, we studied transgenic mice overexpressing IL-9.

Metformin, the popular anti-diabetic drug was shown to exert multiple biological effects. The most recent metformin gained attention as an agent that mobilizes endogenous progenitor cells and enhances regenerative potential of organisms, for example by promoting neurogenesis. In present study, we examined role on mouse olfactory ensheathing (mOECs) derived from animals receiving eight weeks at a concentration equal 2.8 mg/day. mOECs expanded ex vivo were characterized in terms their cellular...

Cryptophycins are a class of 16-membered highly cytotoxic macrocyclic depsipeptides isolated from cyanobacteria. The biological activity is based on their ability to interact with tubulin. They interfere microtubule dynamics and prevent microtubules forming correct mitotic spindles, which causes cell-cycle arrest apoptosis. Their strong antiproliferative activities 100-fold 1000-fold potency compared those paclitaxel vinblastine have been observed. promising drug candidates, as not...

Nowadays, endocrine disorders have become more frequent in both human and veterinary medicine. In horses, reduced physical activity combined with carbohydrate sugar overload may result the development of so-called equine metabolic syndrome (EMS). EMS is characterized by insulin resistance, hyperinsulinemia, elevated blood triglyceride concentrations usually obesity. Although phenotypic features individuals are well known, molecular mechanism underlying disease remains elusive. Therefore,...

The first syntheses of bioactive cryptophycins functionalized at unit D were accomplished in a one-pot Staudinger reduction/cyclization step. An azido precursor for the lower part backbone was introduced to minimize protective group chemistry and enable very convenient synthesis cryptophycin-52 cryptophycin analogues containing an ester or free carboxylic acid bioconjugations. Both new derivatives show high biological activity cytotoxicity assays.

Surgical castration of male piglets without analgesia is a painful procedure. This prospective, randomized and double-blinded study aimed to evaluate the analgesic effects four different local anesthetics for piglet during first week life. In total, 54 aged 3 7 days were distributed into 6 treatment groups: handling (H); pain relief (sodium chloride, NaCl); with anesthetic: 4% procaine (P), 2% lidocaine (L), 0.5% bupivacaine (B) or 20 mg/ml mepivacaine (M). By excluding stress fear as...

Castration of male pigs without anesthesia is a significant welfare issue. Improvac®, GnRH vaccine induces an endogenous immune response leading to decrease in testicular steroids. Consequences different vaccination schemes on function and carcass quality were evaluated immunocastrated boars (IC), surgical castrates (SC), entire males (EM). Therefore, 128 piglets assigned five treatment-groups long term follow-up group. IC groups received two vaccinations (V1, V2) with Improvac® at 8 12, 12...
