Smaller diaphragmatic motor unit potentials (MUPs) compared to MUPs of limb muscles lead to the hypothesis that diaphragmatic muscle fibers, being the generators of MUPs, might be also smaller. We compared autopsy samples of costal diaphragm and vastus lateralis of healthy men with respect to fibers' size and expression of slow myosin heavy chain isoform (MyHC-1) and fast 2A isoform (MyHC-2A). Diaphragmatic fibers were smaller than fibers in vastus lateralis with regard to the mean minimal fiber diameter of slow-twitch (46...

There is an interest globally in using Minimum Unit Pricing (MUP) of alcohol to promote public health. Canada is the only country to have both implemented and evaluated some forms of minimum alcohol prices, albeit in ways that fall short of MUP. To inform these international debates, we describe the degree to which minimum alcohol prices in Canada meet recommended criteria for being an effective public health policy. We collected data on the implementation of minimum pricing with respect to (1) breadth of application, (2) indexation to inflation and (3) adjustments for alcohol content...

BACKGROUND: Many factors may influence the efficacy of cell therapy for intrinsic urinary sphincter deficiency (ISD), including the route of administration of the cells and the condition of the sphincter. The goal of this study was to compare local versus intravenous administration of autologous skeletal muscle precursor cells (skMPCs) when administered to nonhuman primates (NHPs) with either acute or chronic ISD. METHODS: Thirty-two adult female monkeys were divided into eight groups (n = 4/group): (1) control; (2) surgically induced ISD/no treatment; (3) acute ISD (6-week duration)/local vehicle only; (4) acute ISD/local skMPC injection; (5) acute ISD/systemic skMPC; (6) chronic ISD (6-month duration)/local vehicle; (7) chronic ISD/local skMPC; (8) chronic ISD/systemic skMPC...

In the present study the applicability of multispectral UV imaging in combination with multivariate image analysis for surface evaluation of MUPS tablets was investigated with respect to the differentiation of the API pellets from the excipients matrix, estimation of the drug content as well as pellet distribution, and influence of the coating material and tablet thickness on the predictive model. Different formulations consisting of coated drug pellets with two coating polymers (Aquacoat(®) ECD and Eudragit(®) NE 30 D) at three coating levels each were compressed to MUPS tablets with various amounts of coated pellets and different tablet thicknesses...

Muscle motor unit numbers decrease markedly in old age, while remaining motor units are enlarged and can have reduced neuromuscular junction transmission stability. However, it is possible that regular intense physical activity throughout life can attenuate this remodeling. The aim of this study was to compare the number, size, and neuromuscular junction transmission stability of tibialis anterior (TA) motor units in healthy young and older men with those of exceptionally active master runners. The distribution of motor unit potential (MUP) size was determined from intramuscular electromyographic signals recorded in healthy male Young (mean ± SD, 26 ± 5 years), Old (71 ± 4 years) and Master Athletes (69 ± 3 years)...

PURPOSE: Marginal ulcer (MU) is defined as ulcer on the jejunal side of the gastrojejunostomy (GJ) anastomosis. Most MUs are managed medically but those with complications like bleeding or perforation require intervention. It is recommended that GJ anastomosis be revised in patients with MU perforation (MUP). The aim of this case series is to study the clinical presentation and management of MUP. METHODS: Three hundred and thirty-two patients who underwent emergency surgery for perforated peptic ulcer at a single center were studied over a period of 5 years...

Chemical communication is mediated by sex-biased signals abundantly present in the urine, saliva and tears. Because most studies concentrated on the urinary signals, we aimed to determine the saliva proteome in wild Mus musculus musculus, to extend the knowledge on potential roles of saliva in chemical communication. We performed the gel-free quantitative LC-MS/MS analyses of saliva and identified 633 proteins with 134 (21%) of them being sexually dimorphic. They include proteins that protect and transport volatile organic compounds in their beta barrel including LCN lipocalins, major urinary proteins (MUPs), and odorant binding proteins (OBPs)...

The transient enlargement of the compound muscle action potential (M wave) after a conditioning contraction is referred to as potentiation. It has been recently shown that the potentiation of the first and second phases of a monopolar M wave differed drastically; namely, the first phase remained largely unchanged, whereas the second phase underwent a marked enlargement and shortening. This dissimilar potentiation of the first and second phases has been suggested to be attributed to a transient increase in conduction velocity after the contraction...

BACKGROUND: The species Mus musculus experiences an obligate proteinuria: predominant are the Major Urinary Proteins (MUPs), that, collectively known as the major mouse allergen Mus m 1, are among the most important aeroallergens for mouse allergic patients. The production of a soluble and stable hypoallergenic form of Mus m 1 is essential for the development of immunotherapeutic protocols to treat allergic symptoms. METHODS: We introduced the substitution C138S in recombinant Mus m 1...

Major urinary proteins (MUPs) are highly homologous proteoforms that function in binding, transporting and releasing pheromones in house mice. The main analytical challenge for studying variation in MUPs, even for state-of-the-art proteomics techniques, is their high degree of amino acid sequence homology. In this study we used unique peptides for proteoform-specific identification. We applied different search engines (ProteinPilot™vs. PEAKS®) and protein databases (MUP database vs. SwissProt + unreviewed MUPs), and found that proteoform identification is influenced by addressing background proteins (unregulated urinary proteins, non-MUPs) during the database search...

We use counterfactual analysis techniques to evaluate the impact of a $2 minimum unit price (MUP) on the distribution of Australian (Victorian) household off-trade alcohol purchases. Our estimates suggest that a $2 MUP significantly reduces the purchases of at-risk households by up to -0.92 [90% CI: -1.55, -0.28] standard drinks at the highest quantiles and has substantially less effect on households purchasing at light and moderate levels. A $2 MUP may reduce the proportions of male and female shoppers purchasing at the public health threshold of more than two standard drinks per household member per day by -3...

Homocysteine (Hcy) and its metabolites Hcy-thiolactone, N-Hcy-protein, and S-Hcy-protein are implicated in vascular and neurological diseases. However, quantification of these metabolites remains challenging. Here I describe streamlined assays for these metabolites based on their conversion to Hcy-thiolactone. Free Hcy-thiolactone is extracted from the urine with chloroform/methanol. Total Hcy is converted to Hcy-thiolactone in the presence of 1 N HCl. Major urinary protein (MUP)-bound S-linked Hcy is liberated from the protein by reduction with dithiothreitol and converted to Hcy-thiolactone...
