Evidence for sporadic Coxiella burnetii excretion in sheep milk, central Portugal
Pires, Humberto; Silva, S. Santos; Cruz, A.; Cardoso, Luís; Lopes, A.P.; Pereira, M.A.; Nóbrega, C.; Mega, A.C.; Santos, C.; Cruz, R.; Esteves, F.Coxiella burnetii, the causative agent of Q fever, is a globally distributed zoonosis, with cattle, sheep, and goats considered the main reservoirs of the disease (Agger et al,., 2013; Bento et al., 2023). Human transmission primarily occurs through inhaling infections aerosols from milk, faeces, urina, and birth products from infected ruminants. This study used a 2-year longitudinal approach to investigate C. ...
What variables determine sprint performance in young athletes?
Alves, D. L.; Castro, P. H.C. [UNESP]; Freitas, J. V.; De-Oliveira, F. R.; Lima, J. R.P.; Cruz, R.Made available in DSpace on 2020-12-12T01:33:43Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-01-01; Objectives: To identify sprint performance determinants in young athletes in the field in both sexes. Equipment and methods: Two hundred and fourteen track and field athletes, ages between 13 and 15 years old, were divided into validation group (VG) (n = 163) and cross-validation group (CVG) (n = 51).

Caesarean section and neonatal care in the dog.
Mota, M. S. G.; Vala, Helena; Esteves, F.; Cruz, R.; Pisco, S.; Carvalho, P.; Guerreiro, C.; Pacheco, M.; Judas, H.Caesarean section in breeding bitches is an increasingly common practice not only to ensure their future fertility but also the health and safety of offspring. Bitches with high genetic value are often submitted to this procedure. Following the bitch from the moment of mating to the moment of delivery and adequate nursing care of the newborn increases the neonatal survival rates.
Canine hair follicular tumours: a retrospective study
Vala, Helena; Brito, M.; Esteves, Fernando; Cruz, R.; Santos, C.; Mega, A.C.; Nóbrega, C.; Mesquita, JR; Lemos, CHair follicular tumours in dog comprise a large and heterogeneous group of neoplasms that display morphological features resembling one or several portions of the normal hair follicle which constitute a huge effort for its diagnosis. Histopathological evaluation is required to better characterize the different types of canine hair follicular tumours, in order to better understand its biological behaviour and to...
Aplicação das técnicas de deteção de apoptose em ensaios clínicos
Vala, Helena; Ortiz, Ana Liza; Cruz, R.; Venâncio, Carlos; Pires, AR; Francisco, A; Silva, Aura; Faustino-Rocha, AL; Mesquita, João; Ferreira, D.A.A aplicação de metodologias capazes de identificar células apoptóticas constitui uma valiosa ferramenta em vários estudos biomédicos. A hemorragia grave continua a ser a principal causa de morbilidade e mortalidade em animais de companhia vítimas de trauma, situação também comum em humanos, sobretudo jovens vítimas de acidentes de viação. A reperfusão é fundamental, nestas situações, para fomentar a redistribui...
Detection of apoptotic events, using different methods, in renal tissues after ...
Vala, Helena; Cruz, R.; Venâncio, Carlos; Garcia, C.; Silva, Aura; Mesquita, João; Ortiz, Ana Liza; Ferreira, D.A.Apoptosis plays an important role in cellular damage caused by acute renal hypoperfusion. The aim of this study was to detect apoptotic events in an animal model of acute haemorrhage, followed by volume replacement with different intravenous solutions
Hepatic histopathological lesions in acute controled haemorrhage followed by vo...
Vala, Helena; Pina, R.; Cruz, R.; Esteves, F.; Silva, Aura; Mesquita, João; Ortiz, Ana Liza; Ferreira, D.A.The aim of this work was to evaluate the effect of different intravenous solutions used for volume replacement following acute controlled haemorrhage, one crystalloid (RL) and one colloid (HES130/0.4) in the integrity of the hepatic tissue in a pig animal model.
Hepatic histopathological lesions in acute controled haemorrhage followed by vo...
Vala, Helena; Pina, R.; Cruz, R.; Venâncio, C.; Esteves, Fernando; Silva, A.; Mesquita, João; Ortiz, A. L.; Ferreira, D.Introduction: severe hemorrhage remains the major cause of morbidity and mortality in trauma victims or surgical intervened animals, despite of all the advances in the therapeutic approach. The resulting injuries, or even death, are due to the deficit in intravascular volume and subsequent development of hypovolaemic fluid state, leading to poor tissue perfusion and consequent decreased oxygen delivery to the t...
Citologias por aspiração, provenientes de nódulo na narina esquerda (sem envolv...
Vala, Helena; Mesquita, J.; Esteves, F.; Domingues, A. P. C.; Cruz, R.; Santos, C.; Mega, A.O exame histopatológico permite o diagnóstico definitivo, com classificação definitiva e exata, numa percentagem elevada de casos, contudo o exame citológico por ser menos oneroso e rápido é muito adotado na prática clínica diária nos Centros de Atendimento Médico Veterinários, estando descrito como mais indicado em neoplasias sólidas, de origem epitelial, com estroma escasso, linfadenopatias e menos nas neopla...
The importance of oat cells in the diagnosis of Mannheimia haemolytica
Vala, Helena; Themudo, D.; Santos, C.; Mega, A.; Esteves, F.; Cruz, R.; Mesquita, JR.; Nóbrega, C.Introduction Ovine respiratory disease is frequently associated to high economic losses. It can be caused by several aetiological agents, difficulting the diagnosis and the implementation of effective therapeutic measures. The pathologist has a difficult, but very important role, in the diagnostic procedure, based on standard histomorphological classification of lung injury. Objectives The authors describe and ...
