Treatment with etamsylate reduces haemolactia in lactating dairy cows

This Research Communication describes the efficacy of etamsylate to reduce haemolactia in dairy cows. A dairy cow with haemolactia produces milk that is reddish or pinkish due to the presence of blood. Haemolactia causes economic loss because bloody milk is rejected by the industry and the consumers. A total of 58 dairy cows with haemolactia were included in the study and randomly divided into treated (n = 31) and control (n = 27) groups. Treatment consisted of three consecutive daily doses of etamsylate at 15 mg/kg, delivered intramuscularly. Milk production was recorded daily for 7 d, whether or not blood was detected in milk. The mean number of days with the presence of blood in milk in the treatment group was significantly lower (3·4 d) than in the control group (4·9 d). Treatment with etamsylate did not significantly affect milk yield. In conclusion, treatment with etamsylate reduces the number of days blood is observed in milk and it does not have any negative effect on milk production

Mandibular angle augmentation using customized PEEK implants and guides generated with 3D Planning and Printing: case estudies

Mandibular angle augmentation is a procedure that, despite its obvious aesthetic and reconstructive indications, is not routinely performed, even by experienced surgeons. We present a case series of 10 patients treated with custom-made mandibular or inferior border prostheses for aesthetic concerns and sequelae following trauma or orthognathic surgery. Customized implants were designed with CAD/CAM technology, milled from Polyetheretherketone (PEEK) and 3D-printed implant placement guides were used. Ten patients (6 men and 4 women) were included; median age was 36.5 years (28-45 years). Indications for surgery were aesthetics (5 cases) and postoperative sequelae (4 orthognathic surgery and 1 mentoplasty). No significant early complications occurred, except edema and small bruises. Three patients developed wound dehiscence and prosthesis exposure, which closed spontaneously after 2-3 weeks, except one case that required a slight reduction of the upper edge of the prosthesis. No prostheses required removal. After the initial healing period there were no exposures or any late-onset infections or prosthesis intolerance. The use of customized PEEK prostheses together with tooth-supported guides provides treatment that is safe, easier surgically and more reliable. More experience is needed to define bone beauty standards to achieve the desired aesthetic result

Contribuciones a la representación de datos multidimensionales mediante árboles aditivos

[spa] En esta tesis se analiza el problema de la representación asociada a un conjunto sobre el que tenemos definida una distancia verificando el axioma del cuarto punto, realizando un estudio formal de los principales aspectos relacionados con este tipo de representaciones tales como una caracterización de las mismas tratando a través de ella las relaciones entre distancias ultramétricas y aditivas. En concreto, se estudia una estructura de variedad diferenciable sobre el conjunto de las distancias aditivas con configuración inferencia en árboles y confección de algoritmos de construcción de árboles aditivos

On the additive tree representations

En este trabajo se estudia el problema de la representación de un conjunto mediante árboles aditivos, en el sentido de hallar una formalización que permita abordar el mismo desde la perspectiva general de los métodos geométricos de representación del análisis multivariante.In this paper we have studied the problem of the additive tree representation. Our purpose was develop a formal structure that could allow us to analyse that problem from the general perspective of the metric representation method in multivariate data analysis. Moreover, we have studied the relationship between additive tree represen- tations and ultrametric tree representations through this struct ure. On the other hand, this study lends an alternative, from another viewpoint, to the formalitation developed by Buneman (1971).Peer Reviewe
