Deformation-induced transitional myofibroblasts contribute to compensatory lung growth
2016
In many mammals, including humans, removal of one lung (pneumonectomy) results in the compensatory growth of the remaining lung. Compensatory growth involves not only an increase in lung size, but also an increase in the number of alveoli in the peripheral lung; however, the process of compensatory neoalveolarization remains poorly understood. Here, we show that the expression of α-smooth muscle actin (SMA)—a cytoplasmic protein characteristic of myofibroblasts—is induced in the pleura following pneumonectomy. SMA induction appears to be dependent on pleural deformation (stretch) as induction is prevented by plombage or phrenic nerve transection (P < 0.001). Within 3 days of pneumonectomy, …
Evidence for pleural epithelial-mesenchymal transition in murine compensatory lung growth
2017
In many mammals, including rodents and humans, removal of one lung results in the compensatory growth of the remaining lung; however, the mechanism of compensatory lung growth is unknown. Here, we investigated the changes in morphology and phenotype of pleural cells after pneumonectomy. Between days 1 and 3 after pneumonectomy, cells expressing α-smooth muscle actin (SMA), a cytoplasmic marker of myofibroblasts, were significantly increased in the pleura compared to surgical controls (p < .01). Scanning electron microscopy of the pleural surface 3 days post-pneumonectomy demonstrated regions of the pleura with morphologic features consistent with epithelial-mesenchymal transition (EMT); nam…
Remodeling of alveolar septa after murine pneumonectomy
2015
In most mammals, removing one lung (pneumonectomy) results in the compensatory growth of the remaining lung. In mice, stereological observations have demonstrated an increase in the number of mature alveoli; however, anatomic evidence of the early phases of alveolar growth has remained elusive. To identify changes in the lung microstructure associated with neoalveolarization, we used tissue histology, electron microscopy, and synchrotron imaging to examine the configuration of the alveolar duct after murine pneumonectomy. Systematic histological examination of the cardiac lobe demonstrated no change in the relative frequency of dihedral angle components (Ends, Bends, and Junctions) ( P >…
A 3-week feed restriction after weaning as an alternative to a medicated diet: effects on growth, health, carcass and meat traits of rabbits of two g…
2017
Feed restriction after weaning is widely used in meat rabbit farms to promote health and reduce mortality, but this practice impacts negatively on rabbit growth and slaughter performance. This study compared a 3-week post-weaning feed restriction with ad libitum medicated feeding, evaluating effects on feed intake, growth, health, carcass and meat quality of rabbits of two genotypes: Italian White pure breed and Hycole hybrid×Italian White crossbred. A total of 512 rabbits at 36 days of age, of both sexes and two genotypes, were divided into four homogeneous groups assigned, from 36 to 57 days of age, to different feeding programmes (FP): restricted non-medicated (R-N), ad libitum non-medic…
Long-Term Follow-Up of Children with Surgically Treated Vesicorenal Reflux: Renal Growth
1991
Renal growth after successful surgical correction of vesicoureterorenal reflux (VUR) in childhood was observed in 137 female and 22 male patients over a mean follow-up period of 10.5 years. The renal parenchymal area was determined using a compensatory planimeter. For each measured value, the standard deviation score (SDS) was calculated by comparison with a normal population. On average, renal growth after reflux operation nearly paralleled the expected normal growth rate. Scarred kidneys had a worse growth prognosis than refluxing renal units (RU) without renal damage, growth retardation being correlated with the degree of pyelonephritic changes. The diminished growth rate of scarred kidn…
Long-Term Structural and Functional Myocardial Adaptations in Healthy Living Kidney Donors: A Pilot Study
2015
Background and Aims Compensatory renal hypertrophy following unilateral nephrectomy (UNX) occurs in the remaining kidney. However, the long-Term cardiac adaptive process to UNX remains poorly defined in humans. Our goal was to characterize myocardial structure and function in living kidney donors (LKDs), approximately 12 years after UNX. Methods and Results Cardiac function and structure in 15 Italian LKDs, at least 5 years after UNX (median time from donation = 8.4 years) was investigated and compared to those of age and sex matched U.S. citizens healthy controls (n = 15). Standard and speckle tracking echocardiography (STE) was performed in both LKDs and controls. Plasma angiotensin II, a…
The effect of intermittent feeding on feed intake and compensatory growth of whitefish Coregonus lavaretus L.
2009
Abstract Groups of juvenile whitefish, Coregonus lavaretus , were exposed for 6 weeks to three different feeding regimes: control (fed every day); 2 + 5 (fed during weekdays); and 2 + 2 (fed 2 days, starved 2 days). The fish in the 2 + 2 group ate and grew less than the controls but the 2 + 5 group was intermediate and did not differ statistically significantly from either of the other two groups. The fish in both treatment groups exhibited clear compensation for the reduced number of feeding days by increasing intake and consequently weight gain during the days when they were fed, and the compensation increased towards the end of the experiment. Feeding treatments induced clear changes in …
La vessatorietà della provvigione del mediatore in caso di recesso del venditore
2021
La Corte di Cassazione conferma il precedente orientamento favorevole a qualificare come vessatorie le clausole, pattuite nei contratti di mediazione, con le quali le agenzie immobiliari si assicurano il diritto alla provvigione anche in caso di mancata conclusione dell’affare. La soluzione avallata dalla Corte – che nello specifico, per il caso di recesso del venditore, commina la nullita` consumeristica alla clausola con cui il mediatore ottenga un compenso, a prescindere da una commisurazione all’attivita` svolta – si espone, tuttavia, al rischio di traghettare il giudizio di vessatorieta` sulla sponda di un inammissibile sindacato sull’equilibrio economico dello scambio.
Medidas compensatorias en el MERCOSUR
2011
El Mercosur tiene establecido un procedimiento obligatorio de solución de controversias comerciales entre los Estados miembros. Los laudos arbitrales que se dicten son de obligado cumplimiento. Para el caso en el que un Estado miembro no cumpla un laudo arbitral, el Estado afectado le puede imponer unilateralmente medidas compensatorias para garantizar el cumplimiento del laudo. Al estudio de esta posibilidad se dedica este trabajo.
