Abstract
The environment created during embryogenesis contributes to reducing aberrations that drive structural malformations and tumorigenesis. In this study, we investigate the anti-cancer effect of mesenchymal stem cells (MSCs) derived from 2 different gestational tissues, the amniotic fluid (AF) and the chorionic villi (CV), with emphasis on their secretome. Transcriptomic analysis was performed on patient-derived AF- and CV-MSCs collected during prenatal diagnosis and identified both mRNAs and lncRNAs, involved in tissue homeostasis and inhibiting biological processes associated with the etiology of aggressive cancers while regulating immune pathways shown to be important in chronic disorders. Secretome enrichment analysis also identified soluble moieties involved in target cell regulation, tissue homeostasis, and cancer cell inhibition through the highlighted Wnt, TNF, and TGF-β signaling pathways. Transcriptomic data were experimentally confirmed through in vitro assays, by evaluating the anti-cancer effect of the media conditioned by AF- and CV-MSCs and the exosomes derived from them on ovarian cancer cells, revealing inhibitory effects in 2D (by reducing cell viability and inducing apoptosis) and in 3D conditions (by negatively interfering with spheroid formation). These data provide molecular insights into the potential role of gestational tissues-derived MSCs as source of anti-cancer factors, paving the way for the development of therapeutics to create a pro-regenerative environment for tissue restoration following injury, disease, or against degenerative disorders.

Abstract
BACKGROUND Down syndrome (DS) clinical multisystem condition is generally considered the result of a genetic imbalance generated by the extra copy of chromosome 21. Recent discoveries, however, demonstrate that the molecular mechanisms activated in DS compared to euploid individuals are more complex than previously thought. Here, we utilize mesenchymal stem cells from chorionic villi (CV) to uncover the role of comprehensive functional genomics-based understanding of DS complexity. METHODS Next-generation sequencing coupled with bioinformatic analysis was performed on CV obtained from women carrying fetuses with DS (DS-CV) to reveal specific genome-wide transcriptional changes compared to their euploid counterparts. Functional assays were carried out to confirm the biological processes identified as enriched in DS-CV compared to CV (i.e., cell cycle, proliferation features, immunosuppression and ROS production). RESULTS Genes located on chromosomes other than the canonical 21 (Ch. 2, 6 and 22) are responsible for the impairment of life-essential pathways, including cell cycle regulation, innate immune response and reaction to external stimuli were found to be differentially expressed in DS-CV. Experimental validation confirmed the key role of the biological pathways regulated by those genes in the etiology of such a multisystem condition. CONCLUSIONS NGS dataset generated in this study highlights the compromised functionality in the proliferative rate and in the innate response of DS-associated clinical conditions and identifies DS-CV as suitable tools for the development of specifically tailored, personalized intervention modalities.

Abstract
DDT homologues and PCBs were determined in eggs of two stationary species, great crested grebe (Podiceps cristatus) and mallard (Anas platyrhynchos), in three breeding areas of Lake Maggiore in 1998. As expected, much higher contamination levels of both DDTs and PCBs were found in the fish-eating great crested grebe than in the mallard. In many eggs these values exceeded the safety thresholds proposed for aquatic bird protection. However, no significant correlation could be found between the two classes of pollutants and shell thickness in great crested grebe eggs. While a DDT manufacturer was detected as the main source of DDT pollution in the Lake Maggiore environment, the reason for the surprisingly high PCB level remains unknown.

Abstract
The fine morphology of the trophi of bdelloid rotifers was investigated using scanning electron microscopy to provide a detailed description of the structure and to assess its variability within the class. Twelve genera of the four families of Bdelloidea were considered. All trophi studied fit the ramate type typical of bdelloids, and comprise three paired elements: rami, unci (with three groups of teeth: a proximal group of minor teeth, a median group of major teeth with a pore, and a distal group of minor teeth), and manubria. The morphology of the trophi in Adinetida and Philodinida is fairly homogeneous. The trophi of Philodinavida differ in position, orientation, and structure: the proximal group of minor uncus teeth is reduced and the ramus apophysis is more developed. In contrast to the trophi of Flosculariacea, small differences in the number of uncus teeth appear to be taxonomically irrelevant in Bdelloidea. The following features of the trophi are recognized as synapomorphies for the Bdelloidea: absence of the fulcrum; formation of major uncus teeth by fusion of elements; and deposition of calcium as a means of stiffening the manubria. The existence of these synapomorphies suggests that the ramate type of trophi in Bdelloidea does not represent the primitive type in Rotifera.

Abstract
Groups of guinea pigs were injected intramuscularly for 21 days with netilmicin or amikacin 150 mg/kg/day by one or three daily injections. Amikacin was also tested at 225 mg/kg/day with each dosing regimen. Auditory function was evaluated during the experiment by reflexological and electrophysiological tests. Morphological damage to the inner ear was also evaluated. Netilmicin had no effect on the auditory function nor did it damage the organ of Corti. Conversely, amikacin impaired the auditory function and produced loss of hair cells in a dose-related manner. The effect was equally marked with both dosing regimens of 225 mg/kg/day, whereas a slight decrease of auditory impairment was observed with 150 mg/kg administered once a day. The data suggest that administration of a single daily dose of aminoglycosides does not increase the risk of ototoxicity specifically associated with each compound.

Abstract
Pursuant to our identification of prolactin-like immunoreactivity (PLI), widely distributed in rat brain, the spinal cord was examined for the presence of this pituitary-hormone-like protein. PLI was present in all spinal cord extracts examined and averaged 500 +/- 53 pg/mg protein. Hypophysectomy, causing a fall in serum prolactin to undetectable levels, was not associated with any change in levels of PLI in spinal cord. Recovery of rat prolactin standards added to spinal cord homogenates was 97.6 +/- 3.9%. When increasing concentrations of spinal cord extract were assayed in a prolactin radioimmunoassay, displacement of rat 125I-Prolactin from antiserum was parallel to that displacement produced by increasing concentrations of rat anterior pituitary standards. Upon subjection to gel permeation chromatography, the elution profiles of immunoreactive prolactin from spinal cord were different from the profiles of anterior pituitary prolactin. In addition to an immunoreactive prolactin peak eluting with pituitary prolactin, spinal cord extracts showed a large void volume peak and late eluting low-molecular-weight materials not seen with anterior pituitary. In the Nb2 lymphoma cell assay, all spinal cord extracts demonstrated prolactin-like bioactivity with a bioactivity/immunoreactivity ratio of 1.05 +/- 0.13. We conclude: (1) PLI, widely distributed in rat brain, is also present in spinal cord; (2) spinal cord prolactin levels are independent of levels in pituitary and peripheral circulation; (3) this immunoreactive prolactin is bioactive, and (4) differing gel permeation chromatographic elution profiles indicate that there may be some molecular differences between pituitary and spinal cord prolactin.

Abstract
We treated groups of pigmented guinea pigs with either intramuscular netilmicin or dibekacin at 100 and 150 mg/kg per day for 3 weeks. Saline was used as the control solution. All animals were tested weekly for both vestibular and auditory functions. The vestibular function was evaluated by the duration of post-rotatory nystagmus (PRN) elicited by interrupting the rotation of the animal around the vertical axis; auditory function was evaluated by the threshold response for the Preyer's pinna reflex (PPR). All animals were then sacrificed and either their labyrinths or Corti organs were processed for further investigations using the scanning electron microscope (SEM). The duration of PRN decreased over the treatment period in all of the groups as a result of adaptation. However, 150 mg/kg dibekacin produced a significant decrease of the PRN responses as compared to the control and other groups. This effect also continued during the recovery period. Likewise, the PPR threshold of the animals receiving 150 mg/kg dibekacin showed a significant increase at the end of the treatments and during the recovery period, while the other dibekacin group had no significant auditory impairment. Netilmicin at both doses did not significantly affect responses following either vestibular or auditory stimulations. SEM observations demonstrated that the sensory epithelia of the labyrinths and Corti organs affected by 150 mg/kg dibekacin had great losses of stereocilia, while comparable doses of netilmicin (150 mg/kg) had only very moderate losses of stereocilia in the labyrinths but not in the Corti organs.
