Objetivos del estudio: establecer los efectos de ultrasonidos y ondas de choque radiales en el síndrome subacromial, determinar la posible influencia del sexo y analizar la rentabilidad de ambas técnicas. Realizamos un estudio en veinticuatro pacientes repartidos en dos grupos: un grupo recibió ondas de choque y el otro ultrasonidos. Los pacientes fueron evaluados mediante la escala DASH, Constant&Murley, UCLA, SF-36 y EVA, antes del tratamiento, al mes, a los tres meses y a los seis meses. El estudio no mostró diferencias entre ultrasonidos y ondas de choque, aunque ambos tratamientos mostraron eficacia. Dicha mejoría fue mayor en los varones. Obtuvimos un coste por paciente menor con las ondas de choque. Conclusiones: ambas técnicas son eficaces en el tratamiento del síndrome subacromial, aunque no encontramos diferencias estadísticamente significativas entre ellas. Los resultados fueron mejores en los varones. En dichas condiciones, el abordaje con ondas de choque radiales es más rentable. / Objectives: To set the utility of ultrasound and radial shock waves in subacromial syndrome; to determinate the possible influence of sex; to analyse the profitability of both techniques. We did a clinical trial in twenty-four patients, divided in two groups: one of them received shock waves treatment, the other group received ultrasounds. The patients were evaluated using DASH scale, Constant&Murley, UCLA, SF-36 and VAE scales before treatment, one month, three months and six months later. No significant differences were found between the two techniques, although both treatments improved symptoms and function. That improvement was better in males. We obtained a patients’ cost in shock waves group lower than in ultrasounds one. Conclusions: both techniques are effective in the treatment of subacromial syndrome, although we couldn’t find relevant differences. The results were better in males. Thus, radial shock waves treatment is more profitable than ultrasounds one.

I developed a spectrum synthesis method to investigate the physical properties of hot OB main sequence (MS) stars, which are often rapid rotators. The code realistically simulates the surface conditions of rapidly rotating stars, considering the rotationally-deformed stellar shape and gravity darkening effect. Comparing the synthesized absorption line profiles with the observed spectra of the member stars of 19 young Galactic clusters, I determined the projected rotational velocities of 496 stars. The average surface temperature and gravity for most of these objects were then derived from H$\gamma$ line fits. The polar gravity of each star was estimated as a good indicator of the evolutionary status of the star. The derived parameters show that massive rotators spin down during their MS phase. The He abundance data (measured by fitting the He I lines) also favor the theoretical prediction that rotationally-induced mixing can gradually enrich the surface helium abundance through the MS phase. A quicker spin-down is evident in the lower mass star group where a large portion of helium peculiar stars are found. This correlation implies that strong stellar magnetic fields may exist on the surface of these lower mass stars. The same method is also applied to interferometric observations from the CHARA Array of a nearby rapid rotator, Regulus. By combining results from spectroscopic and interferometric analysis, the shape, space orientation, mass, and surface temperature distribution of Regulus are firmly determined. This analysis provides the first evidence of the gravity darkening phenomenon among stars that are not components of an eclipsing binary system. The surprisingly high luminosity determined for Regulus appears to agree with the theoretical prediction that rapid rotator can become more luminous as rotationally-induced mixing brings fresh hydrogen down to the core. Finally I present an extension of the model that simulates the shape, velocity, and temperature variations of a star experiencing nonradial pulsation. I simulated and analyzed the line profile variations in the spectra of $\epsilon$ Per, a B0.7~III star with strong evidence of nonradial pulsation (NRP). A comparison of the model simulations and observations indicates that the pulsations of $\epsilon$ Per have a corresponding local temperature variation that is out of phase with the radial oscillation (a non-adiabatic phase lag).

A solar and diesel-wind hybrid power control systems is proposed in the thesis. The system consists of solar power, wind power, diesel-engine, a static synchronous compensator and an intelligent power controller. MATLAB/Simulink was used to build the dynamic model and simulate the solar and diesel-wind hybrid power system. A static synchronous compensator was used to supply reactive power and regulate the voltage of the hybrid system. To achieve a fast and stable response for the real power control, an intelligent controller was proposed, which consists of the Radial Basis Function Network (RBFN) and the Elman Neural Network (ENN) for maximum power point tracking (MPPT). The pitch angle control of wind power uses ENN controller, and the output is fed to the wind turbine to achieve the MPPT. The solar system uses RBFN, and the output signal is used to control the DC / DC boost converters to achieve the MPPT.

In this paper, we use the newly developed method of particular solution (MPS) and one-stage method of fundamental solution (MFS-MPS) for solving partial differential equation (PDE). In the 1-D Poisson equation, we prove the solution of MFS-MPS is converge to Spectral Collocation Method using Polynomial, and show that the numerical solution similar to those of using the method of particular solution (MPS), Kansa's method, and Spectral Collocation Method using Polynomial (SCMP). In 2-D, we also test these results for the Poisson equation and find the error behaviors.

Radial lip seals are used to prevent leakage between machine elements in many industrial applications. During operation, fluid film between seal lip and shaft surface generates a pressure distribution on the lip which is elastically deformed due to hydrodynamic pressure. Surface roughness parameters in terms of moments of height profile distribution (rms roughness, skewness and kurtosis) affect the rate of oil leakage. A computer program is developed for elastohydrodynamic analysis of radial lip seals. Both the fluid mechanics of the lubricating film and the elastic deformation of the lip are taken into consideration to determine the hydrodynamic pressure distribution and the oil flow through the seal lip. The effect of shaft surface roughness on hydrodynamic analysis is taken into account by using average Reynolds equation with flow factors. For non-Gaussian surfaces, the modified flow factors are used to investigate the effects of skewness and kurtosis on the oil leakage. Numerical tests are performed for different skewness, kurtosis and initial seal tightness values. Results show that when a seal is mounted with a high initial tightness, the hydrodynamic pressure developed is not enough to deform the lip to form a fluid film between the shaft and the seal lip. It is observed that for the same rms roughness and skewness, the side flow rate increases as the kurtosis value increases. However, for the same rms roughness and kurtosis values, the side flow rate decreases for all skewness values.

A bascule bridge is a type of movable bridge that can be opened or closed to facilitate the movement of water-borne traffic such as ships and yachts. Trunnion-Hub-Girder (THG) assembly plays a role as a fulcrum in the bascule bridge. To make the fulcrum, the trunnion is shrink-fitted into the hub, and then the trunnion-hub assembly is shrink-fitted into the girder. Hundreds of thousands of dollars could be lost due to failures during this step. Crack formations in the hubs of various Florida bascule bridges during assembly led the Florida Department of Transportation to commission a project with USF professors to investigate.Finite elements method (ANSYS package) is employed to model the THG assembly procedure and solve for the critical crack length and critical stress in this transient thermal structural problem. Design of experiments (DOE) is used with different cooling processes and the geometrical dimensions of the THG assembly to find the sensitivity of these parameters on the outputs.The influence of the hub outer diameter and the radial interference (between the trunnion and hub) is at different levels on the critical crack length and the stress ratio as it is dependent on fulcrum geometry. If we include four staged cooling methods as follow Type 1: liquid nitrogen Type 2: dry-ice/ alcohol bath followed by liquid nitrogen Type 3: refrigerated air chamber followed by liquid nitrogen Type 4: refrigerated air chamber followed by dry-ice/alcohol bath and then by liquid nitrogenthe cooling type factor contributes the most to both critical crack length (up to 79%) and the stress ratio (up to 84%) in the TH assembling procedures in all three considered bascule bridges. The staged cooling procedure type 2, which is, immersing the TH assembly into the dry ice medium, followed by immersing the TH set into the liquid nitrogen, give larger critical crack length (up to 400%) and stress ratio (up to 87%) compared to the case that used only liquid nitrogen.

This research assesses whether a refinement of the temporal resolution of tree-ring data can improve our understanding of the radial growth-climate relationship. Two study sites in Northern Labrador were chosen, one coastal (Nain), and the other inland (Kamestastin). In Nain, microcore samples were taken weekly from the same five white spruce (Picea glauca) trees over the 2014 growing season. After cross sections were made and stained, the resulting 10µm thin radii provided a direct view of active ring development. In coastal Labrador, radial growth was initiated during the last week of June 2014, and ceased by August 25th. Circumference band dendrometers were installed on white spruce trees at both the Nain and Kamestastin sites. The dendrometers were used to measure micrometre-scale changes over the 2014 growing season. Analogous records of temperature were collected with equal temporal resolution, from an Environment Canada climate station (#8502800), and via a programmable data logger (UX120-006M, Onset HOBO). Correlation function analysis determined the relationship between daily temperature variables and daily variations in stem size. A strong relationship was found between minimum daily temperature and daily stem size at both sites over the eight week long growing season. Traditional dendrochronological sampling methods were utilized to retrieve tree cores from white spruce and eastern larch (Larix laricina) in Nain and Kamestastin. Site-specific master growth chronologies were created using crossdating and standardization techniques. After establishing long term records of monthly temperature and accumulated growing degree-days (GDD) at both study sites, a linear regression analysis was undertaken to determine the suitability of these two variables as predictors of annual-radial growth. An accumulated June/July GDD index was identified as an overall better predictor of annual ring-width than mean monthly temperature variables in northern Labrador. Exploring radial growth on an intra-annual scale helped to improve our understanding of the complex radial growth-climate relationship in Labrador. This allows for a strengthening of tree rings as a proxy climate indicator in remote regions of the northern boreal forest. The findings from this thesis provide the tools necessary to improve upon long-term climate reconstruction and forecasts of boreal forest structure in the face of climate change.

This dissertation describes a new detailed abundance study of field red horizontal branch stars, RR Lyrae stars and blue horizontal branch stars. To carry out this study, we obtained high-resolution and high signal-to-noise ratio echelle spectra at the McDonald observatory and Las Campanas Observatory. In addition, new pulsational emphemerides were derived to analyze the spectra of RR Lyrae stars throughout the pulsational cycles. We find that the abundance ratios are generally consistent with those of field stars of similar metallicity in different evolutionary stages and throughout the pulsational cycles for RR Lyrae stars. We also estimated the red and blue edges of the RR Lyrae instability strip using the derived effective temperatures of RHB and BHB stars. New variations between microturbulence and effective temperature are found among the HB population. For the first time the variation of microturbulence as a function of phase is empirically shown to be similar to the theoretical calculations. Finally, through the study of a rare eclipsing sdB and M dwarf binary, we discovered an unusually low mass for this type of HB star, which observationally proved the existence of a new group of low-mass sdB stars that was theoretically predicted in the past. / text

Η πρωτεΐνη ΒΜ88 είναι νευροειδική πρωτεΐνη με ευρεία κατανομή σε κύτταρα του κεντρικού και περιφερικού νευρικού συστήματος των θηλαστικών. O βιοχημικός χαρακτηρισμός του μορίου έδειξε ότι πρόκειται για διαμεμβρανική πρωτεΐνη που εντοπίζεται κυρίως στις μεμβράνες ενδοκυττάριων οργανιδίων (μιτοχόνδρια, ενδοπλασματικό δίκτυο) ενώ το μεγαλύτερο τμήμα του μορίου της προσανατολίζεται προς το κυτταρόπλασμα. Στο ενήλικο κεντρικό νευρικό σύστημα η πρωτεΐνη ΒΜ88 εκφράζεται σε νευρώνες ενώ δεν ανιχνεύεται σε γλοιοκύτταρα. Αναπτυξιακά, η έκφραση της πρωτεΐνης ΒΜ88 ανιχνεύεται κατά την έναρξη της νευρογένεσης στον εγκέφαλο του αρουραίου ενώ τα επίπεδα της έκφρασή της αυξάνονται µε την ηλικία και παραµένουν υψηλά στο ενήλικο ζώο. Λειτουργικά πειράματα in vitro υπερέκφρασης της πρωτεΐνης ΒΜ88 συσχετίζουν την πρωτεΐνη ΒΜ88 με την έξοδο των κυττάρων από τον κυτταρικό κύκλο και την έναρξη της διαδικασίας διαφοροποίησής τους προς νευρωνικό φαινότυπο. Τα παραπάνω δεδομένα μας ώθησαν να μελετήσουμε την έκφραση της πρωτεΐνης ΒΜ88 κατά τη διαδικασία της νευρογένεσης και της διαφοροποίησης των νευρώνων in vivo, έτσι ώστε να διερευνήσουμε το ρόλο της κατά την ανάπτυξη του εγκεφάλου. Για το σκοπό αυτό επιλέξαμε ως σύστημα μελέτης τον αναπτυσσόμενο φλοιό του τελεγκεφάλου των τρωκτικών. Αρχικά χαρτογραφήθηκε η έκφραση της πρωτεΐνης ΒΜ88 στο φλοιό του αναπτυσσόμενου τελεγκεφάλου κατά την εμβρυϊκή ηλικία Ε14-Ε18 και πραγματοποιήθηκαν πειράματα διπλού ανοσοφθορισμού με αντισώματα έναντι της πρωτεΐνης ΒΜ88 και έναντι μαρτύρων του κυτταρικού πολλαπλασιασμού όπως είναι η κυκλίνη D1 (μάρτυρας της φάσης G2/M του κυτταρικού κύκλου) και το ανάλογο της θυμιδίνης BrdU (που ενσωματώνεται κατά τη φάση της αντιγραφής του DNA - φάση S του κυτταρικού κύκλου). Τα αποτελέσματα αυτών των πειραμάτων έδειξαν ότι η πρωτεΐνη ΒΜ88 εκφράζεται τόσο στους διαφοροποιημένους νευρώνες, όσο και σε ενεργά πολλαπλασιαζόμενα προγονικά κύτταρα του αναπτυσσόμενου φλοιού του αρουραίου και του ποντικού. Κατόπιν, διερευνήσαμε αν η πρωτεΐνη ΒΜ88 εκφράζεται κατά την περίοδο της νευρογένεσης ειδικά, σε προγονικά κύτταρα της γενεαλογίας των νευρώνων ή αν εκφράζεται και σε πρόδρομα κύτταρα της γλοιϊκής γενεαλογίας του τελεγκεφάλου. Για το σκοπό αυτό πραγματοποιήθηκαν διπλές και τριπλές ανοσοϊστοχημικές χρώσεις με αντισώματα έναντι της πρωτεΐνης ΒΜ88 και έναντι νευρωνικών ή γλοιΐκών μαρτύρων, σε συνδυασμό με αντισώματα έναντι μαρτύρων κυτταρικού πολλαπλασιασμού. Παρατηρήθηκε ότι η πρωτεΐνη ΒΜ88 εκφράζεται αποκλειστικά και μόνο σε κύτταρα της νευρωνικής γενεαλογίας και όχι σε πολλαπλασιαζόμενα ή διαφοροποιημένα κύτταρα της γλοιϊκής γενεαλογίας. Τα παραπάνω αποτελέσματα επιβεβαιώθηκαν από το γεγονός ότι η έκφραση της πρωτεΐνης ΒΜ88 προσδιορίστηκε και σε νευροεπιθηλιακά κύτταρα του τύπου «ακτινωτής γλοίας» που σύμφωνα με την τρέχουσα αντίληψη, αποτελούν την πλειοψηφία του πληθυσμού των πρόδρομων νευρογενετικών κυττάρων του φλοιού κατά την εμβρυϊκή ηλικία Ε14-Ε18. Αργότερα μόνο, τα κύτταρα αυτά θα αποτελέσουν προδρόμους της γλοιϊκής γενεαλογίας, και συγκεκριμένα μετά τη 18η εμβρυϊκή ημέρα και κατά τις πρώτες ημέρες μετά τη γέννηση. Στη συνέχεια πραγματοποιήθηκαν συνδυαστικά πειράματα σήμανσης των πρόδρομων κυττάρων του εγκεφάλου με δύο διαφορετικούς μάρτυρες της φάσης S του κυτταρικού κύκλου, με τα οποία έγινε εφικτή η παρακολούθηση in vivo, και για το διάστημα 12 και 24 ωρών, του πολλαπλασιασμού, της μετανάστευσης και της διαφοροποίησης μιας ομάδας πρόδρομων νευρικών κυττάρων. Τα πειράματα αυτά οδήγησαν στο συμπέρασμα ότι η έκφραση της πρωτεΐνης ΒΜ88 σχετίζεται με τις ασύμμετρες κυτταρικές διαιρέσεις, η εμφάνιση των οποίων σηματοδοτεί την έναρξη της νευρογένεσης στο φλοιό και την εμφάνιση των πρώτων μεταμιτωτικών νευρώνων. Έτσι, φαίνεται ότι η έκφραση της πρωτεΐνης ΒΜ88 στα πρόδρομα νευρογενετικά κύτταρα προκαλεί την έξοδό τους από τον κυτταρικό κύκλο. Η έκφραση της πρωτεΐνης ΒΜ88 μελετήθηκε και στον εγκέφαλο του ενήλικου αρουραίου όπου εντοπίστηκε, εκτός από τους ώριμους νευρώνες, και στα πρόδρομα κύτταρα του πρόσθιου μεταναστευτικού τόξου (RMS) όπου λαμβάνει χώρα η δευτερογενής νευρογένεση. Το αποτέλεσμα αυτό έρχεται σε συμφωνία με τις προηγούμενες παρατηρήσεις μας και συνδέουν επιπλέον την έκφραση της πρωτεΐνης ΒΜ88 με τη διαδικασία της νευρογένεσης στον ενήλικο εγκέφαλο. Τέλος, μελετήσαμε τόσο την έκφραση της πρωτεΐνης ΒΜ88 όσο και τα επίπεδα μεταγραφής του γονιδίου ΒΜ88 στον αναπτυσσόμενο εγκεφαλικό φλοιό ποντικών που φέρουν τη μετάλλαξη Small eye (ποντίκια Sey/Sey). Στα ποντίκια αυτά δεν είναι λειτουργικό το γονίδιο Pax6 που είναι υπεύθυνο για την επαγωγή της νευρογένεσης στο ραχιαίο μέρος του τελεγκεφάλου. Έτσι, ο αριθμός των νευρώνων που παράγονται στο φλοιό αυτών των μεταλλαγμένων ποντικών είναι ελαττωμένος στο μισό από αυτόν που συναντάμε στα ποντίκια φυσικού τύπου. Όπως αναμενόταν, παρατηρήθηκε ότι τόσο η έκφραση της πρωτεΐνης ΒΜ88 όσο και τα επίπεδα μεταγραφής του γονιδίου ΒΜ88 είναι μειωμένα στα ποντίκια Sey/Sey. Συμπερασματικά, τα αποτελέσματα της εργασίας μας έδειξαν ότι η πρωτεΐνη ΒΜ88 χαρακτηρίζει τη γενεαλογία των νευρώνων από τα πρόδρομα εμβρυϊκά κύτταρα μέχρι τους ώριμους νευρώνες και επομένως αποτελεί ένα νέο μάρτυρα της νευρωνικής γενεαλογίας. Επιπλέον, δείξαμε ότι η πρωτεΐνη ΒΜ88 συγκεντρώνει τις απαραίτητες ιδιότητες που χαρακτηρίζουν ένα «νευρογενετικό παράγοντα». Συγκεκριμένα: α) εκφράζεται τόσο στους διαφοροποιημένους νευρώνες όσο και σε ενεργά πολλαπλασιαζόμενα κύτταρα της νευρωνικής γενεαλογίας, β) δεν εκφράζεται σε πρόδρομα κύτταρα της γλοιϊκής γενεαλογίας, γ) εκφράζεται σε πρόδρομα κύτταρα νευρώνων κατά τη διάρκεια της νευρογένεσης στο ενήλικο άτομο και τέλος δ) η έκφρασή της μειώνεται σε ζώα που φέρουν μεταλλάξεις οι οποίες έχουν ως αποτέλεσμα την εμφάνιση ελαττωματικής νευρογένεσης. Η κατανομή της πρωτεΐνης ΒΜ88 κατά την ανάπτυξη του εγκεφάλου καθώς και ο εντοπισμός της σε βλαστικά κύτταρα του ενήλικου εγκεφάλου, η συσχέτιση της έκφρασης του μορίου με τις ασύμμετρες νευρογενετικές κυτταρικές διαιρέσεις καθώς και η χαρακτηριστική αύξηση των επιπέδων έκφρασης της πρωτεΐνης ΒΜ88 κατά τη μετάβαση των προγονικών κυττάρων σε διαφοροποιημένους νευρώνες, όλα συνηγορούν για τη συμμετοχή του μορίου στις διαδικασίες της εξόδου από τον κυτταρικό κύκλο και τη διαφοροποίηση των νευρώνων in vivo. Οι παρατηρήσεις αυτές, όχι μόνον είναι συμβατές με προηγούμενα πειραματικά δεδομένα όσον αφορά τον προσδιορισμό του ρόλου της πρωτεΐνης σε in vitro βιολογικά συστήματα, αλλά δημιουργεί ενδιαφέρουσες προοπτικές για την αξιοποίηση της πρωτεΐνης ΒΜ88 σε θεραπευτικές προσεγγίσεις για την αντιμετώπιση νευροεκφυλιστικών ασθενειών ή/και τραυματισμών του εγκεφάλου. / BM88 is a neuron-specific protein widely expressed in the cells of the mammalian central and peripheral nervous system. Its biochemical characterization revealed that is an integral membrane protein, located at the membranes of intra-cellular organelles (mitochondria, endoplasmic reticulum) with the bulk of the protein facing towards the cytoplasm. In the adult central nervous system BM88 is expressed in neurons but it is not detected in glial cells. During development, BM8 is initially expressed at the onset of neurogenesis in the rat brain, its levels rise along age and remain high in the adult. In vitro experiments of BM88 protein over-expression suggest that BM88 is implicated in cell cycle exit and the initiation of differentiation into a neuronal phenotype. These findings lead us to study the expression of BM88 during neurogenesis and neuronal differentiation in vivo in purpose to investigate its role in brain development. For this reason, we have chosen as a model of study the developing cortex of rodent telencephalon. Initially, we investigated the distribution of BM88 protein in the developing cortex. To this end, we performed double-labeling experiments in sections from the developing rat brain at embryonic days E14 and E18 using antibodies to BM88 and markers of the cell cycle such as cyclin D1 (G2/M phase marker) and BrdU, a thymidine analogue that is incorporated during DNA replication (S phase marker). The findings from these experiments revealed that BM88 protein is expressed in the differentiated neurons as well as in actively proliferating progenitor cells of the developing cortex of rat and mouse. We next sought to investigate whether BM88 is expressed during neurogenesis specifically in the progenitor cells of the neuronal lineage or in the progenitor cells of the glial lineage of the telencephalon as well. For this reason we performed double and triple-labeling experiments with antibodies to BM88 and to markers of the neuronal or glial lineages, in combination with markers of the cell cycle. We observed that BM88 protein is expressed exclusively in the neuronal progenitors and never in the proliferating or differentiated cells of the glial lineage. The above results were supported also by the fact that BM88 protein was detected in neuroepithelial “radial glial” cells that are cells recently reported to be the majority of neuronal progenitors of the cortex during the embryonic days E14-E18. These cells will turn into glial progenitors only after the embryonic day E18 and during early postnatal days. Moreover, we developed an experimental protocol that allowed us to mark the progenitor cells of the brain with two different markers of the S phase of the cell cycle. Thus, we could observe in vivo, during a period of 12 and 24 hours, the migration and differentiation of a group of neural progenitor cells. The results from this experiment lead us to the conclusion that the expression of BM8 protein is associated with the asymmetric cell divisions that mark the onset of neurogenesis in the cortex and the appearance of the first post-mitotic neurons. Thus, it appears that the expression of BM88 protein in the neuronal progenitor cells causes their exit from the cell cycle. BM88 protein expression was also detected in the adult rat brain, not only in the mature neurons but also in the precursor cells of the rostral migratory stream (RMS), where the secondary neurogenesis occurs. This result is in accordance with our previous observations and support additionally that there is a correlation between BM88 expression and the process of neurogenesis in the adult brain. Finally, we investigated the expression of BM88 protein as well as the transcriptional levels of BM88 gene in the developing cortex of Small eye mutant mice (Sey/Sey mice). These mice lack the functional Pax6 gene that is responsible for the induction of neurogenesis in the dorsal telencephalon. Thus, the number of neurons that are produced in the cortex of the mutant mice is reduced by half in comparison to that of the wild type mice. As expected we observed reducer levels of expression both of BM88 protein and BM88 transcripts in the Sey/Sey mice. To conclude, the results of our study demonstrate that BM88 protein marks the lineage of neurons, all along from the stage of embryonic precursor cells to the stage of mature neurons, and for this reason is a new marker of the neuronal lineage. Furthermore, we showed that BM88 protei has all the characteristics that can identify a molecule as a “neurogenic factor”. More specifically: a) it is expressed both in differentiated neurons and in actively proliferating cells of the neuronal lineage, b) it is absent in the precursors of the glial lineage, c) it is present in the adult neuronal precursors, and finally d its expression is reduced in mutants with neurogenic defects. The expression pattern of BM88 protein during brain development, its presence in stem cells in the adult brain, its association with the asymmetric divisions of neurons as well as the characteristic high levels of BM88 protein expression during the neuronal transition from the progenitor stage to the differentiated stage, all together coincides to the implication of BM88 in the exit from the cell cycle and in the differentiation of neurons in vivo. These observations not only agree with previous experimental data, but also create new perspectives for the use of BM88 protein in therapeutic approaches in order to control the neurodegenerative diseases or/and brain damages.
