Insecticide ear tags numerically improve grazing cattle performance

Stocker cattle grazing pastures during the summer months face challenges due to horn flies, which can result in reduced weight gains and less efficient use of forages. One strategy for controlling horn flies is insecticide-impregnated ear tags. The use of pesticide ear tags may be an effective management practice to improve overall productivity during a grazing season. The objective of this study was to evaluate the efficacy of insecticide ear tags as a means of improving growth of stocker calves grazing native pastures in the Flint Hills region of Kansas

Parentes silvestres de plantas cultivadas para a alimentação e agricultura nativos ou naturalizados no Pampa.

O presente estudo visa inventariar os parentes silvestres de plantas cultivadas para a alimentação e agricultura, nativos ou naturalizados no Pampa, verificar o pool gênico e cultivos aos quais estão relacionados, o estado de conservação, a representatividade em bancos de germoplasma e a distribuição geográfica no bioma.Dissertação (Mestrado em Ciências) - Programa de Pós-graduação em Agronomia, Faculdade de Agronomia Eliseu Maciel, Universidade Federal de Pelotas.

Clarity on Cannabinoid-Based Products in Medicine

The perception of cannabis in society has changed over the last decades, leading to an increasing permissiveness about its use mainly across Western countries. This has happened in parallel to the growing study of the possible role of cannabinoid-based products in medicine. The cannabis plant contents comprise more than one hundred different cannabinoids, each binding differently to numerous human body targets. This cannabinoids administration, either isolated, combining some of them, or as a full plant extract can produce many different risk–benefit effects in humans depending on the product composition. Moreover, we have seen the appearance of synthetic cannabinoids. As expected, doses and different routes of administration introduce further variability. Cannabinoid-based pharmaceutical products authorised for medicinal use after comprehensive research and with approval by regulatory medicines agencies, such as the European Medicines Agency (EMA) and U.S. Food and Drug Administration (FDA), should be distinguished from cannabinoid-based products (whether standardised or not) that aimed for medicinal use but lack submitted efficacy, tolerability, and safety scientific evidence for regulatory approval. Distribution of some of the latter products are still allowed in certain geographical areas. There are also cannabinoid products used mainly recreationally or as food supplements and ruled separately. In a detailed white paper, this review describes the present situation, depicting the societal and medical state of the art, collecting the facts-based risk–benefit features of already available cannabinoid-based products, and also the future possibilities in medicine, which can be vast if proper research is develope

Position-Dependent Dysfunction of Deep Brain Stimulation in Tourette Syndrome: Diagnostic Clues

Background: Detection of defective deep brain stimulation (DBS) contacts/electrodes is sometimes challenging. Case Report: We report a patient with Tourette syndrome (TS), who presented with abrupt tic increase and mild generalized headache 9 years after DBS implantation. On the suspicion of a hardware defect, a fracture of the DBS electrode and extension lead was ruled out by radiography and standard implantable pulse generator readouts. Further investigation revealed position-dependent modifiable therapeutic impedances, suggesting an impaired contact of the extension lead/adaptor. After replacement normal impedances were recorded, and the patient fully recovered. Discussion: In DBS dysfunction with inconspicuous hardware check, position-dependent defects might be suspected

Effects of Limit Feeding Cold Stressed Growing Calves in the Morning Versus the Evening, as well as Bunk Line Sharing on Performance

Objective: To determine the response of cold stressed growing calves to being fed in the evening instead of morning hours, as well as the effect of bunk line sharing. Study Description: Crossbred steers (n = 360) of Texas, Oklahoma, and Idaho origin were blocked by weight into four size groups and randomly assigned to pens, which were randomly allocated to one of five treatments. All steers received a diet formulated to provide 60 Mcal net energy for gain/100 lb of dry matter and were limit fed with a target of 2.0% of their body weight in dry matter intake. Treatments consisted of being fed in the morning (AM), in the evening (PM), fed half of their feed in the morning and half in the evening (50/50), and two treatments that allowed cattle to be fed in the same pen yet were rotated twice daily utilizing a holding pen, allowing for half of the calves to be fed in the morning (Shuttle AM) and half to be fed in the evening (Shuttle PM), doubling the use of the pen and bunk line. The steers were fed for 77 days and individual animal weights were taken on day -1 (allocation), day 0 (initial processing), day 64/65 (blood sampling), and day 77 (final weights). Plasma glucose was obtained individually on day 64 and 65, and pen weights were collected on days 0, 21, 28, 35, 56, 63, 70, and 77. The Bottom Line: When limit feeding cold stressed growing calves, neither shifting from morning feed delivery to evening feed delivery, nor bunk line sharing signifi­cantly improves the efficiency of feed conversion

European clinical guidelines for Tourette syndrome and other tic disorders:summary statement

In 2011 a working group of the European Society for the Study of Tourette syndrome (ESSTS) developed the first European Guidelines for Tourette syndrome (TS) published in the ECAP journal. After a decade ESSTS now presents updated guidelines, divided into four sections: Part I: assessment, Part II: psychological interventions, Part III: pharmacological treatment and Part IV: deep brain stimulation (DBS). In this paper, we summarise new developments described in the guidelines with respect to assessment and treatment of tics. Further, summary findings from a recent survey conducted amongst TS experts on these same topics are presented, as well as the first European patient representative statement on research. Finally, an updated decision tree is introduced providing a practical algorithm for the treatment of patients with TS. Interestingly, in the last decade there has been a significant shift in assessment and treatment of tics, with more emphasis on non-pharmacological treatments
