Background/Objectives: Hepatocellular carcinoma (HCC) is a major cause of cancer-related deaths rising worldwide. This leading to an increased demand for liver transplantation (LT), the most effective treatment HCC in its initial stages. However, current patient selection criteria are limited predicting recurrence and raise ethical concerns about equitable access care. study aims enhance by refining HepatoPredict (HP) tool, machine learning-based model that combines molecular clinical data...
Most donkey and local horse breeds are vulnerable to extinction as mechanization of agriculture progress throughout the world. The present study analyzed pedigree herd records Asinina de Miranda breed (RAM), identifying genealogical human factors that may affect genetic diversity in future suggesting suitable strategies preservation, early on conservation program. breeding rate was very low, with a ratio foaling/live animals 0.23 (178/760). estimated number founders ancestors contributing...
In equids, health and welfare depend on body composition. A growing number of equids are now used as leisure companion animals, often found overfeed. The need for a close monitoring fatness led to the search tools allowing rapid non-invasive estimation fatness. This study intends assess real-time ultrasonography (RTU) usefulness in establishing relationship between ultrasound measures subcutaneous fat-plus-skin thickness (SF-Skin) condition score (BCS) horses donkeys. Forty-three healthy...
The aim of the present study is to define and compare predictive power two different Bayesian models for donkey sperm quality after evaluation linear combined testicular biometry indices their relationship with age body weight (BW). Testicular morphometry was ultrasonographically obtained from 23 donkeys (six juveniles 17 adults), while 40 ejaculates eight mature were analyzed output assessment. regression analyses considered build statistical using gel-free volume, concentration, total...
The donkey breed Asinina de Miranda, with fewer than 1000 breeding females, is in danger of extinction. objectives this study were to predict the progression under present management and identify determinants for survival, by means a population viability analysis program, order suggest suitable strategies. simulation showed high risk most critical factor survival was percentage females per year, but actual needed depended on carrying capacity breed. Reducing female mortality age at...
Toxoplasma gondii and Leishmania infantum are zoonotic protozoal parasites. Serum samples were obtained from 186 donkeys (Equus africanus asinus) Portugal assessed for antibodies to T. by the modified agglutination test (MAT). For titration of spp. direct was used (DAT). Eleven seropositive with titres 20 (n = 7), 80 2), 640 1) ≥ 2560 1). One donkey (titre 800). Donkeys in exposed can be infected
The Miranda donkey (Equus asinus) is an endangeredasinine from do Douro region, located in the north east of Portugal. We studied antimicrobial resistance and virulence genes Escherichia coli Enterococcus spp. isolates these animals.In March 2014, a total 66 faecal samples were recovered independent animals. Antibiotic was determined by disc diffusion method. Carriage coding for antibiotic-resistant virulent factors analysed PCR.A E. 41 enterococcal detected, with faecium (61 %) hirae (24...

Contents This study aims to characterize the reproductive patterns in A sinina de M iranda jennies during non‐breeding season. Reproductive activity was surveyed 12 females, aged between 3 and 18 years old, using ultrasound teasing with a jack. The animals were monitored from S eptember pril, six each consecutive year. Of these nine showed disruption normal pattern of ovarian Loss cyclicity included anoestrus (41.7%), silent ovulatory oestrus (25%), persistence corpus luteum (8.3%). Only...
Jennies' follicular wave patterns have not yet been addressed during the non-breeding and transition seasons in anoestrous jennies. Twelve non-pregnant females of Miranda donkey breed were followed to describe characteristics non-reproductive season determine effect patterns. Five jennies enrolled this study experienced anoestrus season, but all retained continuous emergence waves. The average duration waves from peak was 11.2 ± 0.021 days (3-29 days). different type 9.91 0.034 for minor...
In endangered donkey populations, reproductive performance is one the most important areas to study, provided its connection with conservation opportunities. Among traits, knowledge on evolution of seminal qualitative and quantitative parameters may achieve a particular relevance given implication improved or more efficient fertility fecundation chances. The aim present study was model gonadosomatic index along age in Miranda donkeys. Forty semen collections from 8 donkeys 2.8 21.6 years...
The authors describe two cases of cervical hypoplasia in jennets, detected during the gynaecological evaluation purebred females Portuguese donkey breed Asinina de Miranda. These jennets aged 10 and 15 years were referred for consultation by local breeders association because infertility an artificial breeding programme. In both cervix was small, shorter than usual closed. one females, outflow semen insemination reported. Clinical ultrasonographic genital tract demonstrated that ovaries...
Due to the long courtship needed attain excitation and erection, donkey semen collection can take up 90 min. ProstaglandinF2α (PGF2α) has been reported hasten onset of erection ejaculation in domesticated mammals, presumably by inducing smooth muscle contractions internal genitalia. However, while it anecdotally used donkeys, yet be critically evaluated. This study aimed compare behavioral parameters Catalan, Balearic, Amiata, Miranda jacks treated with PGF2α analogue cloprostenol sodium...
ABSTRACT The main goals of this study were to document and compare the normal ranges testicular haemodynamic parameters in pre‐ (aged 8–12 months; n = 4) postpubertal 24–259 16) Miranda donkeys breeding season, correlate animal biometric data Doppler indices with basic semen quality sexually mature jacks. Colour pulsed‐Doppler ultrasonography employed assess blood flow left right distal supratesticular artery (DsTA) their marginal branches (marginal arteries—MA). Peak systolic velocity...
