CYSTIC OVARIAN FOLLICLES AND THYROID ACTIVITY IN THE DAIRY COW
No full textThyroid activity affects the functionality of the reproductive axis and thyroid dysfunction has been associated with ovarian hyperstimulation syndrome and polycystic ovarian syndrome, in human medicine. This study investigates serum17- < beta> estradiol, progesterone, thyrotropic and thyroid hormone levels, in cyclic dairy cows on heat (Group H) and in dairy cows with ovarian follicular cysts (Group FC). Both 17- < beta> estradiol and progesterone serum concentrations were statistically higher in cystic than in cyclic cows (estradiol: 8.51 ± 1.91 vs 6.32 ± 1 pg/mL) (progesterone: 0.49 ± 0.17 vs 0.13 ± 0.03 ng/mL), whereas TSH and fT4 serum concentrations were statistically lower in cows with cystic ovarian follicles (COF), compared to cyclic ones (TSH: 2.48 ± 1.31 vs 3.56 ± 1.03 ng/mL) (fT4: 5,86 ± 1.69 vs 8.63 ± 1.08). fT3 serum levels were similar, in both cystic and cyclic subjects (2.94 ± 0.65 vs 3.02 ± 0.9, respectively). Standing on these results, a look to the functioning of thyrotropic axis should be given in dairy cows with COF, just like it is routinely performed in human gynaecology, in case of ovarian diseases. If severe hypothyroidism should be found, a hormone replacement therapy could be attempted in cystic cows refractory to “ordinary” therapies
Musica e compensazione dei DSA. Proposte didattiche tra neuroscienze e ricerca evidence-based
No full textIl presente volume propone un viaggio culturale e operativo attraverso le diverse dimensioni
dell’impiego della musica per l’inclusione, con particolare attenzione alla progettazione di
attività efficaci da proporre in classi della scuola del I ciclo frequentate da allieve e allievi con
Disturbi Specifici di Apprendimento (DSA).
L’inclusione scolastica è un processo continuo e laborioso di rimozione degli ostacoli
all’apprendimento e alla partecipazione, un percorso da intraprendere con passione e
competenza anche da parte degli insegnanti di musica e di strumento musicale.
Esso richiede cambiamenti accurati e trasversali, a livello di valori, politiche, cultura educativa
e pratiche didattiche, che siano in grado di potenziare la capacità del sistema di soddisfare le
diverse esigenze di istruzione e di garantire il successo scolastico, formativo e il diritto allo
studio di tutti, creando contesti di apprendimento autentici, significativi e opportunamente
sfidanti ed efficaci per tutti.
Tutti i contributi prendono spunto dai più recenti studi scientifici nell’ambito delle neuroscienze
e della ricerca educativa, offrendo un panorama aggiornato sugli aspetti teorici, normativi e
didattici di cui tener conto per un’organizzazione inclusiva ed efficace della didattica della
musica e dello strumento musicale nel I ciclo di istruzione. Nella seconda parte del volume,
vengono inoltre presentate proposte operative basate sulle attuali ricerche scientifiche
Stress e patologie neonatali di un gruppo di Lichi del Nilo (Kobus Megaceros) ospitati presso il Bioparco di Roma
No full textEffect of neostigmine on contractility of equine pre-ovulatory follicles: an in vitro study.
No full textIn this study, the Authors investigated the modulatory effect of three single doses (106, 105, and 104 M) of neostigmine on the spontaneous contractility of equine pre-ovulatory follicles in an isolated organ bath, to establish the relationship between this acetylcholinesterase inhibitor and ovulation, in the mare. The results indicate that neostigmine increases pre-ovulatory contractility in equine follicles at each dose, but in a different manner. Indeed, the rise in contractility induced by neostigmine at 106 M and 104 M was phasic, while at 105 M it was tonic. The data obtained indicate possible implications of these drugs in the pharmacological modulation of equine ovulation
Roles of Reactive Oxygen Species in Female Reproduction.
No full textReactive oxygen species (ROS) are highly reactive oxidizing agents. Cells, under aerobic conditions, have a defence system against ROS, and in normal circumstances, there is an appropriate balance between pro-oxidants and antioxidants. When an overproduction of ROS develops or the body fails to eliminate ROS in excess, oxidative stress arises, during which ROS accumulate and damage cells and tissues. Besides their noxious effects, accumulating data have shown that controlled and adequate ROS concentrations exert physiologic functions. Different studies have confirmed the presence of ROS and the transcripts of the various antioxidant enzymes in the female reproductive tract. When ROS production overwhelms antioxidant defences, oxidative stress occurs, which may deeply threaten the anatomical and functional integrity of the genital tract. This review addresses the main physiological and pathological roles exerted by ROS and their scavenging systems in several processes involved in the main physiological functions of the female reproductive tract of both women and domestic animals. Particularly, the involvement of the oxidant system in several reproductive processes is investigated, such as follicular development, ovarian steroidogenesis, ovulation, corpus luteum formation and function, luteolysis, germ cell function, maintenance of pregnancy and beginning of parturition
Candida glabrata and pre-term premature rupture of membrane complicating in vitro pregnancy: case report and confirmation of mother to neonate transmission
No full textWe report a case of Candida glabrata infection in an in vitro fertilization-assisted pregnancy complicated by pre-term pre-labor rupture of the membranes. We found C. glabrata in gastric fluid, amniotic fluid and maternal vaginal swab. Neonatal and maternal isolates showed indistinguishable molecular patterns analyzed by fingerprint DNA multilocus
