RESUMEN
Exercise-induced proteinuria has been widely investigated in humans, also in relation to intensity and duration of activity. Instead, there are only limited publications regarding urinary biochemical parameters and urinary proteins before and after physical activity in dogs. This paper aimed to investigate the effects of exercise on urinary biochemistry and proteins in military dogs. Twenty-four dogs were enrolled in this study. All the dogs were clinically sound, and they were examined before and after activity. Pulse rates (PR) and respiratory rate (RR) were monitored. Urine was sampled before and after a training session of search activity. Standard urinalysis was carried out, urine total proteins and creatinine were measured and the urinary protein:creatinine ratio was calculated; finally, the urinary proteins were separated using sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE). Clinical examination before and after activity did not reveal any pathological finding. After activity, the PR was slightly increased, while the RR was notably increased (p < 0.05). Total proteins, albumin, and their ratio with creatinine were significantly higher after exercise when considering all the dogs included or only the females while, when considering only the males no significant difference was detected. The clinical relevance of this study was related to the possibility of using urine as a non-invasive sample for monitoring health status after training activity and exercise in dogs. An increase in microalbuminuria after search activity, measured using SDS-PAGE could be considered an early biomarker of renal function during training sessions.

The intergovernmental organization known as the United Nations (UN) was born "to maintain international peace and security" through different operations and tasks, including "mine action" and "explosive detection". Explosives are the most frequent cause of injuries in military personnel and an enormous danger for civilians. The role of explosive detection dogs (EDDs) and mine detection dogs has gained great consideration over time, leading to their intense use in military operations. Literature regarding working injuries reported by EDDs during missions is limited. The aim of the present study is to investigate the hematological changes that occurred between pre- and post-mission blood analyses in military working dogs deployed to Afghanistan in order to evaluate signs of health problems or physical adjustments. Examining the clinical records, only three dogs reported a medical issue, one with gastric dilatation-volvulus (GDV), and two with lameness episodes. Lack of health issues occurring during the missions was reflected by the absence of significant differences between pre- and post-mission blood analyses. Blood results were also examined by dividing the EDDs into groups considering age at departure, sex, breed and mission length. A few categories demonstrated significant changes in some parameters; however, the mean values were always included in the ranges of normality, indicating that their physical fitness and training were adequate for the required tasks.
RESUMEN
Stem cells from extra-embryonic sources can be obtained by non-invasive procedures. We have standardized a method for the expansion of equine umbilical cord-derived matrix cells (EUCMCs) for potential therapy. EUCMCs were isolated from the umbilical cord of five mares immediately after delivery. For expansion, cells were grown in alpha-MEM and MSCBM. Moreover, to measure the effect of growth factor supplementation, epidermal growth factor (EGF) was added to alpha-MEM. alpha-MEM and MSCBM media performed similarly in terms of population doubling and CFU number value. EGF supplementation of alpha-MEM determined a significant increase of the population doubling value. EGF supplementation did not affect the adipogenic and chondrogenic differentiation while bone nodule sizes an increased with the osteogenic protocol. Both alpha-MEM and MSCBM can be used to cultivate EUCMCs. alpha-MEM supplemented with EGF might represent an advantage for EUCMCs expansion. The results could be useful in choosing the culture medium since alpha-MEM is more cost-effective than MSCBM.
