Abstract
Deregulation of small non-coding RNAs (sncRNAs) has been associated with the onset of metastasis. We evaluated the expression of sncRNAs in patients with early-stage breast cancer, performing RNA sequencing in 60 patients for whom tumor and sentinel lymph node (SLN) samples were available, and conducting differential expression, gene ontology, enrichment and survival analyses. Sequencing annotation classified most of the sncRNAs into small nucleolar RNA (snoRNAs, 70%) and small nuclear RNA (snRNA, 13%). Our results showed no significant differences in sncRNA expression between tumor or SLNs obtained from the same patient. Differential expression analysis showed down-regulation (n = 21) sncRNAs and up-regulation (n = 2) sncRNAs in patients with locoregional metastasis. The expression of SNHG5, SNORD90, SCARNA2 and SNORD78 differentiated luminal A from luminal B tumors, whereas SNORD124 up-regulation was associated with luminal B HER2+ tumors. Discriminating analysis and receiver-operating curve analysis revealed a signature of six snoRNAs (SNORD93, SNORA16A, SNORD113-6, SNORA7A, SNORA57 and SNORA18A) that distinguished patients with locoregional metastasis and predicted patient outcome. Gene ontology and Reactome pathway analysis showed an enrichment of biological processes associated with translation initiation, protein targeting to specific cell locations, and positive regulation of Wnt and NOTCH signaling pathways, commonly involved in the promotion of metastases. Our results point to the potential of several sncRNAs as surrogate markers of lymph node metastases and patient outcome in early-stage breast cancer patients. Further preclinical and clinical studies are required to understand the biological significance of the most significant sncRNAs and to validate our results in a larger cohort of patients.

Abstract
The deregulation of microRNAs (miRNAs) is associated with the various steps of the metastatic process. In addition, circulating miRNAs are remarkably stable in peripheral blood, making them ideal noninvasive biomarkers for disease diagnosis. Here, we performed a proof-of-principle study to determine whether tumor-tissue-derived miRNAs are traceable to plasma in ER-positive early breast cancer patients. We performed RNA-sequencing on 30 patients for whom plasma, sentinel lymph nodes (SLNs) and tumor tissue were available. We carried out differential expression, gene ontology and enrichment analyses. Our results show that circulating miRNAs are inversely expressed compared with tumor tissue or SLNs obtained from the same patients. Our differential expression analysis shows the overall downregulation of circulating miRNAs. However, the expression of miR-643a-3p and miR-223 was up-regulated in patients with positive SLNs. Furthermore, gene ontology analysis showed the significant enrichment of biological processes associated with the regulation of epithelial cell proliferation and transcriptional regulation commonly involved in the promotion of metastases. Our results suggest the potential role of several circulating miRNAs as surrogate markers of lymph node metastases in early breast cancer patients. Further preclinical and clinical studies are required to understand the biological significance of the most significant miRNAs and to validate our results in a larger cohort of patients.

Abstract
BACKGROUND Although auditory verbal hallucinations (AVH) are a core symptom of schizophrenia, they also occur in non-psychotic individuals, in the absence of other psychotic, affective, cognitive and negative symptoms. AVH have been hypothesized to result from deviant integration of inferior frontal, parahippocampal and superior temporal brain areas. However, a direct link between dysfunctional connectivity and AVH has not yet been established. To determine whether hallucinations are indeed related to aberrant connectivity, AVH should be studied in isolation, for example in non-psychotic individuals with AVH. METHOD Resting-state connectivity was investigated in 25 non-psychotic subjects with AVH and 25 matched control subjects using seed regression analysis with the (1) left and (2) right inferior frontal, (3) left and (4) right superior temporal and (5) left parahippocampal areas as the seed regions. To correct for cardiorespiratory (CR) pulsatility rhythms in the functional magnetic resonance imaging (fMRI) data, heartbeat and respiration were monitored during scanning and the fMRI data were corrected for these rhythms using the image-based method for retrospective correction of physiological motion effects RETROICOR. RESULTS In comparison with the control group, non-psychotic individuals with AVH showed increased connectivity between the left and the right superior temporal regions and also between the left parahippocampal region and the left inferior frontal gyrus. Moreover, this group did not show a negative correlation between the left superior temporal region and the right inferior frontal region, as was observed in the healthy control group. CONCLUSIONS Aberrant connectivity of frontal, parahippocampal and superior temporal brain areas can be specifically related to the predisposition to hallucinate in the auditory domain.

Abstract
Sperm cryopreservation causes various types of damage, including membrane injury, oxidative stress, and loss of the acrosome. In cattle, the mortality rate after sperm cryopreservation reaches roughly 50%, and surviving sperm cells have a lower motility and lower fertility than their fresh counterparts. Large variations are also observed between bulls. The aim of this study was to analyse different motility parameters before and after freezing in order to establish correlations. The final objective is to determine, before freezing, parameters that could predict the characteristics of motility after freezing. A computer-assisted sperm analyser (Hobson Sperm Tracker) was used. We analyzed one ejaculate from 30 different bulls before and after freezing (minimum 300 spermatozoa/analysis). Reliable parameters (<10% variation for the same ejaculate) were then selected and included VCL (curvilinear velocity), VAP (average path velocity), MAD (mean angular head displacement), ALH (amplitude of lateral head displacement), STR (straightness of path), and the percentage of motility (%Mot). Linear regressions were established between those parameters before and after freezing. Results are shown in Table 1. The velocity parameters (VAP, VCL, and STR) of the motile sperm were conserved after freezing. Moreover, ejaculates with a high proportion of motile sperm before freezing have, on average, better values for velocity parameters after freezing, while no correlation was found between the percentage of motile sperm before and after freezing. The only parameter of fresh sperm that seems to be correlated with the proportion of motile sperm cells after freezing is MAD (inverse correlation). This could mean that an ejaculate with a high proportion of spermatozoa showing important lateral displacements of the head is more sensitive to cryopreservation. Similarly, a high MAD before freezing was related to a low velocity after thawing. A high MAD could result from a high proportion of capacitated spermatozoa, which is detrimental to their survival and motility. In conclusion, few parameters related to the motility can predict the proportion of motile sperm after freezing. However, by combining several parameters, it seems possible to predict the characteristics of motility of the sperm. Although further investigations are needed, the present evaluation could be of interest to evaluate the freezability of ejaculates, to understand variations between bulls, or to set up new freezing protocols.

Abstract
We studied groups of 39 schizophrenic subjects, 35 schizotypic subjects, and 33 control subjects, comparing them on a standard sustained attention task called the Continuous Performance Test (identical pairs version). The expected negative relationship between performance on sustained attention and psychopathology was confirmed by differences among the three groups which were in the direction predicted, although only the difference between the schizophrenic group and the other two groups was significant. This finding adds evidence to the view from research on high risk and attention with schizophrenic subjects that subtle attention deficits are present among subjects within the schizophrenia spectrum. Consequently, our results can be understood as supporting a dimensional theory of psychopathology.
