Economic consequences of mastitis and withdrawal of milk with high somatic cell count in Swedish dairy herds

The main aim was to assess the impact of mastitis on technical and economic results of a dairy herd under current Swedish farming conditions. The second aim was to investigate the effects obtained by withdrawing milk with high somatic cell count (SCC). A dynamic and stochastic simulation model, SimHerd, was used to study the effects of mastitis in a herd with 150 cows. Results given the initial in

Relationship between somatic cell count and milk yield in different stages of lactation

The association between somatic cell count (SCC) and daily milk yield in different stages of lactation was investigated in cows free of clinical mastitis (CM). Data were recorded between 1989 and 2004 in a research herd, and consisted of weekly test-day (TD) records from 1,155 lactations of Swedish Holstein and Swedish Red cows. The main data set (data set A) containing 36,117 records excluded TD

Mastitis control in Swedish dairy herds

The aim of this study was to investigate which preventive measures targeting mastitis are implemented in Swedish dairy herds with different housing and milking systems. Data were collected through a self-administered postal questionnaire sent to 898 dairy farmers, stratified by housing and milking system, in May 2011. The questionnaire contained general questions about the herd and the person resp

Which preventive measures against mastitis can increase the technical efficiency of dairy farms?

The aim of this paper was to explore if, and in that case how, various preventive measures against mastitis influenced the whole-farm economic outcome, measured as technical efficiency, of a sample of specialised dairy farms in Sweden. In particular, the paper aimed at analysing whether a change to preventive measures applied by fully efficient farms would be a way for inefficient farms to become

Relationship between herd-level incidence rate of energy-related postpartum diseases, general risk factors and claw lesions in individual dairy cows recorded at maintenance claw trimming.

Laminitis and energy-related postpartum diseases share several risk factors, indicating a common etiology. Thus, a herd's incidence rate of energy-related postpartum diseases, such as displaced abomasum and clinical ketosis, might reflect the likelihood of cows to suffer from laminitis-related claw lesions. The aim of this study was to investigate the association between herd-level incidence rate

Proteomic Profiling for Cardiovascular Biomarker Discovery in Orthostatic Hypotension

Orthostatic hypotension (OH) has been linked with higher incidence of cardiovascular disease, but little is known about the mechanisms behind this association. We aimed to identify cardiovascular disease biomarkers associated with OH through a proteomic profiling approach. Seven hundred seventy-eight patients with unexplained syncope or orthostatic intolerance underwent head-up tilt test and supin

Low-frequency electromagnetic stimulation may lead to regression of Morris hepatoma in buffalo rats

OBJECTIVE: The influence of low-frequency electromagnetic (LF-EM) waves on the processes of carcinogenesis and tumor growth has been the subject of experimental investigations for more than two decades and the results are promising. In parallel, an interesting method of complementary medicine, biophysical-information therapy (BIT) or bioresonance therapy (BRT), which in principle is based on LF-EM

Accuracy of Clinical Tests in Detecting Disk Herniation and Nerve Root Compression in Subjects With Lumbar Radicular Symptoms

Objectives: To investigate the accuracy of 3 commonly used neurodynamic tests (slump test, straight-leg raise [SLR] test, femoral neurodynamic test) and 2 clinical assessments to determine radiculopathy (radiculopathy I, 1 neurologic sign; radiculopathy II, 2 neurologic signs corresponding to 1 specific nerve root) in detecting magnetic resonance imaging (MRI) findings (extrusion, subarticular ner

Serum cathepsin B activity during regression of Morris hepatoma 5123 D

BACKGROUND: Serum cathepsin B activity has been considered a potential marker of tumor progression. We previously demonstrated that low-frequency electromagnetic stimulation (LF EMS), called bioresonance therapy (BRT), may both accelerate and inhibit the growth of transplantable hepatoma (Morris type 5123D), including total tumor regression. The aim of this study was to assess serum cathepsin acti

Since the mid 1970's, when Adey discovered that extremely-low-frequency electromagnetic field (ELF EMF) may affect the calcium ions efflux from various cells, bioeffects of non-ionizing radiation (NIR) have become the subject of growing interest and numerous research projects. At present, the fact that NIR exerts both stimulatory and inhibitory effects on different physiological cellular parameter

In recent years we have observed how electromagnetic (EM) radiation enters our daily life. The strength of man-made EM field is often far above the natural level and this finding has encouraged a large group of researchers to investigate its possible health effect. Non-ionizing radiation and extremely low-frequency electric and magnetic fields have been the subject of intensive theoretical and exp

Immune tolerance induction : What have we learned over time?

Development of inhibitory antibodies to infused factor VIII (FVIII) concentrates continues to be the most serious complication of haemophilia A management. Induction of immune tolerance by administering high doses of FVIII concentrate (antigen) and prothrombin complex concentrates to control bleeding was originated in the 1970s in Bonn, Germany, by Dr Hans-Hermann Brackmann, and became known as th

Glioma grade discrimination with MR diffusion kurtosis imaging : A meta-Analysis of diagnostic accuracy

Purpose: To assess the diagnostic test accuracy and sources of heterogeneity for the discriminative potential of diffusion kurtosis imaging (DKI) to differentiate low-grade glioma (LGG) (World Health Organization [WHO] grade II) from high-grade glioma (HGG) (WHO grade III or IV). Materials and Methods: The Cochrane Library, Embase, Medline, and the Web of Science Core Collection were systematicall

The Role of Airway Inflammation and Bronchial Hyperresponsiveness in Athlete's Asthma

Purpose Asthma is frequently reported in endurance athletes. The aim of the present study was to assess the long-term airway inflammatory response to endurance exercise in high-level athletes with and without asthma. Methods In a cross-sectional design, 20 asthmatic athletes (10 swimmers and 10 cross-country skiers), 19 athletes without asthma (10 swimmers and 9 cross-country skiers), and 24 healt

A case of computational thinking: The subtle effect of hidden dependencies on the user experience of version control

We present some work in progress based on observations of the use of version Control systems in two different software development organizations. We consider the emergent user experience, and analyze the structure of the conceptual model and its presentation to see how this experience is formed. We consider its impact on the adoption of such tools outside software engineering and suggest future li

Disordered eating in a Swedish community sample of adolescent girls : Subgroups, stability, and associations with body esteem, deliberate self-harm and other difficulties

Background: The developmental study of subtypes of disordered eating (DE) during adolescence may be relevant to understand the development of eating disorders. The purpose of the present study was to identify subgroups with different profiles of DE in a community sample of adolescent girls aged 13-15 years, and to study the stability of these profiles and subgroups over a one-year interval in orde
