Fertility indices, such as non-return rate and number of services per conception, have worsened significantly over the past few years. Because oestrus detection is one of the major factors influencing these indices, this study was performed to determine whether, how long, and at what time dairy cows show signs of oestrus in their behaviour. Two high(More)
OBJECTIVE To evaluate the effect of natural udder infection with minor pathogens on subsequent natural infection with major pathogens. SAMPLE POPULATION 7 dairy herds with low bulk milk somatic cell count. PROCEDURE During a 20-month prospective study, milk samples were collected from diary cows at regular intervals and from quarters with clinical signs(More)
The phenotype of DM2 shows similarities as well as differences to that of Myotonic Dystrophy type 1 (DM1). Gastrointestinal dysfunction is common in DM1 and 25% of the patients consider this to be the most disabling consequence of the disease. Little is known about gastrointestinal involvement in Myotonic Dystrophy type 2 (DM2). The aim of the study was to(More)
The phenotype of myotonic dystrophy type 2 (DM2) shows similarities as well as differences to that of myotonic dystrophy type 1 (DM1). Dysphagia, a predominant feature in DM1, has not yet been examined in DM2. In a recent nationwide questionnaire survey of gastrointestinal symptoms in DM2, 12 out of 29 DM2 patients reported to have difficulty in swallowing(More)
Limbic encephalitis is characterized by subacute onset of short-term memory loss, seizures, sleep disturbances, as well as psychiatric and behavioral symptoms. A subgroup is associated with voltage-gated potassium channel antibodies (VGKC-Abs). In many cases, brain magnetic resonance imaging (MRI) demonstrates hyperintense areas in the medial part of the(More)
This article reviews the influence of machine milking on udder health. The main risks are transmission and penetration of pathogens during milking. Pathogens can be transmitted via the hands, cloths, and liners. Irregular fluctuations in the vacuum can cause penetration of mastitis pathogens into or through the teat canal. Such fluctuations are caused by(More)
The effect of 100 IU human chorionic gonadotrophin (hCG) on testicular capillary blood flow was studied in adult male rats using a 133Xe clearance method and a radioactive microsphere technique. To investigate the role of Leydig cells in regulation of testicular blood flow after treatment with hCG, rats were pretreated with ethane dimethylsulphonate (EDS)(More)
An effective method of interrupting testicular blood flow temporarily and repeatedly in the ram has been developed. Blockade of flow has been achieved mechanically by an inflatable occluder placed around the testicular artery at the level of the spermatic cord. The effect of the blockade on total testicular blood supply was investigated using Doppler(More)
Myotonic dystrophy type 2 (DM2) is a rare, autosomal dominant, multisystem disorder with proximal weakness, myotonia, pain and cataract as important symptoms. Given the assumed underreporting of DM2 in the Netherlands combined with the predominant role of pain in DM2 as well as in fibromyalgia syndrome (FMS), we hypothesized there will be an excess(More)
