In this paper we prove the universal property of skew PBW extensions generalizing this way the well known universal property of skew polynomial rings. For this, we will show first a result about the existence of this class of non-commutative rings. Skew PBW extensions include as particular examples Weyl algebras, enveloping algebras of finite-dimensional Lie algebras (and its quantization), Art...

Swainsonine is the primary toxin in locoweeds. It causes intention tremors, reproductive dysfunction, emaciation, and death. The objective of the present study was to evaluate the potential reproductive and developmental toxicities caused by swainsonine in mice. The treatment groups consisting of three generations of mice were given a range of concentrations of swainsonine by intraperitoneal in...

Aquatic mammals, such as cetaceans experience various depths, with accordingly diverse oxygenation, thus, cetaceans have developed adaptations for hypoxia, but mechanisms underlying this tolerance to low oxygen are unclear. Here we analyzed VHL and HIF-2α, in the hypoxia signaling pathway. Variations in VHL are greater than HIF-2α between cetaceans and terrestrial mammals, and beluga whale VHL ...

OBJECTIVE To compare reported birth weight (BW) information in school health records with BW from medical birth records, and to investigate if maternal and offspring characteristics were associated with any discrepancies. DESIGN Register-based cohort study. SETTING Denmark, 1973-1991. PARTICIPANTS The study was based on BW recorded in the Copenhagen School Health Records Register (CSHRR) ...

Objective: To determine whether patients load the operated eg at a prescribed weight-bearing target load during postoprative recovery. Design: A descriptive prospective study. Setting: Orthopedic clinic and patients’ homes. Participants: Fifty patients who had undergone total hip rthroplasty (THA) with trochanteric osteotomy. Intervention: Patients were verbally instructed by a physial therapis...

The effect of ordinary and restricted selection indices on body weight at different ages changes in birth weight of Iranian Moghani sheep was studied. Traits in the aggregate genotype were birth weight (BW), body weights at 3 (BW3) and 12 months of age (BW12). Two ordinary selection indices (I1 and I2) and two restricted selection indices (R1 and R2) were constructed. BW and BW3 were included i...
