Relationship between reticular pH parameters and potential on-farm indicators in the early lactation of dairy cows.

Subacute ruminal acidosis (SARA) is an important nutritional disorder affecting animal welfare and economy of milk production. Definitions rely on ruminal pH but due to limitations of its measurement, indicators reflecting low pH are highly desirable. The aim of this study was to investigate the relationship between reticular pH and 18 on-farm indicators in milk, blood, faeces, urine and chewing behaviour in early lactating dairy cows.

Development of a subacute ruminal acidosis risk score and its prediction using milk mid-infrared spectra in early-lactation cows.

A routine monitoring for subacute ruminal acidosis (SARA) on the individual level could support the minimization of economic losses and the ensuring of animal welfare in dairy cows. The objectives of this study were (1) to develop a SARA risk score (SRS) by combining information from different data acquisition systems to generate an integrative indicator trait, (2) the investigation of associations of the SRS with feed analysis data, blood characteristics, performance data, and milk composition, including the fatty acid (FA) profile, (3) the development of a milk mid-infrared (MIR) spectra-based prediction equation for this novel reference trait SRS, and (4) its application to an external data set consisting of MIR data of test day records to investigate the association between the MIR-based predictions of the SRS and the milk FA profile. The primary data set, which was used for the objectives (1) to (3), consisted of data collected from 10 commercial farms with a total of 100 Holstein cows in early lactation.

An Innovative Concept for a Multivariate Plausibility Assessment of Simultaneously Recorded Data.

The aim of this work was to develop an innovative multivariate plausibility assessment (MPA) algorithm in order to differentiate between 'physiologically normal', 'physiologically extreme' and 'implausible' observations in simultaneously recorded data. The underlying concept is based on the fact that different measurable parameters are often physiologically linked. If physiologically extreme observations occur due to disease, incident or hormonal cycles, usually more than one measurable trait is affected.

Assessing project approval procedures as formalised forms of public participation.

Formalised public participation in project approval procedures is rarely addressed in technology assessment. Empirical data about public participation processes are taken into account even more rarely. This article explores the practice of public participation in infrastructure projects in the Federal Republic of Germany on the basis of empirical data from the period of 1990 to 2010.

Relative bioavailability and pharmacodynamic effects of methantheline compared with atropine in healthy subjects.

Objectives: Methantheline is a strong muscarinic receptor blocking drug used in the treatment of overactive bladder syndrome, hypersalivation and hyperhidrosis. To provide basic information on the pharmacokinetics, magnitude of pharmacodynamic (PD) effects and their correlations with plasma concentrations, we performed a clinical study in 12 healthy subjects receiving methantheline as immediate-release coated tablets (IR) or in watery solution (SOL) in comparison with atropine and placebo tablets.

Methods: The pharmacokinetics and influence of methantheline, atropine and placebo on salivation and accommodation and pupil function (pupillometry: diameter, response to light flash) were studied in a randomized, controlled study after the administration of 100 mg methantheline bromide as IR and in SOL (phase 1) and 1.
