Investigating teeth eruption and eating quality
In Australia, a sheep ceases to be a lamb as soon as the eruption of its first permanent incisor teeth is evident. As part of a wider program to investigate a number of aspects of sheep meat eating quality, a project was undertaken to determine whether lamb eating quality would be compromised if sheep with partially erupted teeth continued to be classified as lamb.
Overall, the results indicated that meat from young sheep with partially erupted teeth was unlikely to be inferior in eating quality than the meat currently classified as lamb
Photography-based taxonomy is inadequate, unnecessary, and potentially harmful for biological sciences
The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed by the Code has already been discussed in Zootaxa (Dubois & NemĂ©sio 2007; Donegan 2008, 2009; NemĂ©sio 2009aâb; Dubois 2009; Gentile & Snell 2009; Minelli 2009; Cianferoni & Bartolozzi 2016; Amorim et al. 2016). This question was again raised in a letter supported
by 35 signatories published in the journal Nature (Pape et al. 2016) on 15 September 2016. On 25 September 2016, the following rebuttal (strictly limited to 300 words as per the editorial rules of Nature) was submitted to Nature, which on
18 October 2016 refused to publish it. As we think this problem is a very important one for zoological taxonomy, this text is published here exactly as submitted to Nature, followed by the list of the 493 taxonomists and collection-based
researchers who signed it in the short time span from 20 September to 6 October 2016
Multicenter retrospective evaluation of transmural migration of subcutaneous ureteral bypass devices within the digestive tract in cats.
BackgroundPlacement of a subcutaneous ureteral bypass (SUB) device is an effective method to relieve all causes of ureteral obstruction in cats. Complications involving migration within the gastrointestinal tract have been seldomly described.ObjectivesTo characterize transmural migration of SUB devices within the digestive tract in cats.AnimalsEleven migrated SUB catheters identified in 8 cats between 2017 and 2021.MethodsRetrospective review of medical records of cats with a SUB device in which migration into the gastrointestinal tract was identified.ResultsThe median time from SUB device placement to implant migration was 928âdays (201-2298âdays). Seven cats had obstruction of the SUB device and a positive urine culture at diagnosis. The migration was identified by ultrasound in 6/11, pre-operative contrast radiography in 2/2, and only at time of surgery in 3 SUB devices. All cats underwent surgical correction. Four nephrostomy and 7 cystotomy catheters migrated. Migration occurred into the duodenum (3/11), jejunum (7/11), and colon (1/11). SUB devices were removed in 7 cats and replaced in 2 cats, with 1 cat diagnosed with 2 migration events. Gastrointestinal resection and anastomosis were performed in 7/8 cats and an enterotomy in 2 cats. Six cats survived to discharge. The median follow-up time after migration diagnosis was 365âdays (range, 0-1114âdays) and 2 cats are still alive.Conclusions and clinical importanceAlthough a rare complication, migration of SUB device should be considered in cats with SUB device obstruction and a positive urine culture
