Brain organoids as innovative tool for regenerative medicine
The introduction of the tridimensional (3D) organoids technology is revolutionizing the fields of developmental and stem cell biology and it is emerging as the latest frontier in regenerative medicine for the treatment of neurodegenerative disorders, such as epilepsy. The overall objective of my PhD thesis was to set the stage to develop functional hippocampal brain organoid that can be used for regenerative medicine to cure the Temporal Lobe epilepsy (TLE)

Variability of nutrient and thermal structure in surface waters between New Zealand and Antarctica, October 2004-January 2005
We describe the upper ocean thermal structure and surface nutrient concentrations between New Zealand and Antarctica along five transects that cross the Subantarctic Front, the Polar Front (PF) and the southern Antarctic Circumpolar Current (ACC) front. The surface water thermal structure is coupled with variations in surface nutrient concentrations, making water masses identifiable by both temperature and nutrient ranges. In particular, a strong latitudinal gradient in orthosilicate concentration is centred at the PF. On the earlier sections that extend south-west from the Campbell Plateau, orthosilicate increases sharply southward from 10ā15 to 50ā55 Āµmol lā1 between 58Ā° S and 60Ā° S, while surface temperature drops from 7Ā°C to 2Ā°C. Nitrate increases more regularly toward the south, with concentrations ranging from 10ā12 Āµmol lā1 at 54Ā° S to 25ā30 Āµmol lā1 at 66Ā° S. The same features are observed during the later transects between New Zealand and the Ross Sea, but the sharp silica and surface temperature gradients are shifted between 60Ā° S and 64Ā° S. Both temporal and spatial factors may influence the observed variability. The January transect suggests an uptake of silica, orthophosphate and nitrate between 63Ā° S and 70Ā° S over the intervening month, with an average depletion near 37%, 44% and 29%, respectively. An N/P (nitriteā+ānitrate/orthophosphate) apparent drawdown ratio of 8.8Ā±4.1 and an Si/N (silicic acid/nitriteā+ānitrate) apparent drawdown ratio >1 suggest this depletion results from a seasonal diatom bloom. A southward movement of the oceanic fronts between New Zealand and the Ross Sea relative to prior measurements is consistent with reports of recent warming and changes in the ACC
Prostorna raspodjela fizikalnih, kemijskih i bioloŔkih oceanografskih karakteristika, fitoplanktona, hranjivih tvari i otopljene obojane organske materije (CDOM) u Bokokotorskom zaljevu na Jadranu
The temporal variations of temperature, salinity, fluorescence, dissolved oxygen concentration, Coloured Dissolved Organic Matter (CDOM) and of chemical (nutrients, chlorophyll a) and biological (phytoplankton composition) parameters in the Boka Kotorska Bay were observed during two periods. CDOM regulates the penetration of UV light into the sea and therefore plays an important role in many hydrological and biogeochemical processes in the sea surface layer including primary productivity. In the framework ADRICOSM-STAR it was possible to investigate the Boka Kotorska Bay during May and June 2008 in order to increase an understanding of optical and chemical characteristics and their evolution during these periods. In both periods station KO (located furthest from the open sea) presented different physical, chemical and biological characteristics with respect to the other stations inside the Boka Kotorska Bay. A positive correlation was found between CDOM and chlorophyll a (R = 0.7, P < 0.001, n = 15) and this implies that in this area, similarly to the open sea, the primary source of CDOM should be the biological production from phytoplankton. This is probably due to the fact that the rivers entering the Boka Kotorska Bay are not severely impacted by man.U Bokokotorskom zaljevu su mjerene vremenske promjene temperature, saliniteta, fluorescencije, koncentracije otopljenog kisika, obojene otopljene organske materije (CDOM) i kemijskih (hranjive soli, klorofila) i bioloÅ”kih (sastav fitoplanktona) parametara tijekom dva razdoblja (svibanj i lipanj 2008. godine). CDOM odreÄuje prodiranje UV svjetlosnih zraka u more i stoga igra vrlo važnu ulogu u mnogim hidroloÅ”kim i biogeokemijskim procesima u povrÅ”inskom sloju mora koji ukljuÄuje primarnu produkciju. Unutar ADRICOSM-STAR projekta, bilo je moguÄe istražiti Bokokotorski zaljev tijekom svibnja i lipnja 2008. godine radi poveÄanja razumijevanja optiÄkih i kemijskih karakteristika i njihovog razvoja kroz ova razdoblja. Zbog dotoka krÅ”kih rijeka i smanjenja razmjene s otvorenim morem, u oba razdoblja postaja KO (smjeÅ”tena najdalje od otvorenog mora) je pokazala razliÄite fizikalne, kemijske i biolo{ke karakteristike u odnosu na postaje unutar Bokokotorskog zaljeva. PronaÄena je pozitivna korelacija izme|u CDOM i klorofila a (R = 0.7, P < 0.001, n = 15) {to upuÄuje na to da bi u ovom podruÄju, sliÄno otvorenom moru, primarni izvor CDOM trebao biti bioloÅ”ka produkcija od fitoplanktona. To je vjerojatno zbog toga Å”to dotoci rijeka u Bokokotorskom zaljevu nisu ozbiljnije ugroženi ljudskim djelovanjem
Karakterizacija razliÄitih obalnih podruÄja Jadrana u kasno proljeÄe
The objective of this study is to analyze the physical and chemical characteristics of three coastal zones of the Adriatic Sea during late spring, and to identify similarities and differences among the
zones. The trophic status of the Southeastern Adriatic-Sea, dominated by the discharge from the Buna/Bojana river delta watersheds, is compared with two other Adriatic regions: the Northwestern Adriatic Sea and the Southwestern Adriatic Sea (Gulf of Manfredonia); the first is dominated by the Po River freshwater discharge and the second is one of the most productive areas of the Southwestern Adriatic.
The areas are influenced by two main Adriatic surface currents: the Eastern Adriatic Current (EAC) that flows north-westward, and the Western Adriatic Current (WAC) that flows south-eastward. The measurements of temperature, salinity, fluorescence, oxygen, nutrients and chlorophyll a in the three areas were collected and compared. The areas showed similar physical and bio-chemical characteristics, despite the Northern
Adriatic is impacted by the Po River runoff and the WAC carries out along the Western Adriatic water rich of nutrients from the northern Italian rivers. The area affected by the Po River discharge showed maximum chlorophyll and nitrogen concentrations within the river plume. Moreover, the
Southwestern Adriatic Sea showed a load of nutrients and organic matter connected to substances coming from the northern Italian rivers (mainly the Po River). Similarly, in the Southeastern
Adriatic-Sea, the Buna/Bojana River discharge contained relatively high values in the regional chlorophyll distribution. The three areas are directly or indirectly linked to river plume dynamics and the associated inorganic and organic inputs determine the trophic state of the areas. In particular, the Southeastern Adriatic Sea was a meso-eutrophic area; despite the most eastern side of the Adriatic was an oligotrophic basin.Cilj ovog istraživanja je analiza fizikalnih i kemijskih svojstava triju obalnih podruÄja Jadrana u kasno proljeÄe i ustanovljenje sliÄnosti i razlika meÄu zonama. TrofiÄki status jugoistoÄnog Jadran-
skog mora, pod utjecajem dotoka slatke vode iz sliva rijeke Bune / Bojane, je u ovom radu usporeÄen s druge dvije jadranske regije: sjeverozapadnim Jadranom i jugozapadnim Jadranom (zaljev Man
-fredonia) u prvom dominiraju pražnjenja rijeke Po, dok je drugi jedno od najproduktivnijih podruÄja jugozapadnog Jadrana.
PodruÄja su pod utjecajem dviju glavnih povrÅ”inskih struja Jadranskog mora: istoÄne jadranske struje (EAC) koja teÄe prema sjeverozapadu i zapadne jadranske struja (WAC) koja teÄe prema jugo-istoku. podaci o izmjerenoj temperaturu, slanosti, fluorescenciji, kisiku, hranjivim tvarima i klorofilu a su sakupljeni i usporeÄeni za sva tri podruÄja. Istraživana podruÄja su pokazala sliÄne fiziÄke
i bio-kemijske karakteristike, unatoÄ Äinjenici da je sjeverni Jadran pod utjecajem dotoka rijeke Po, a zapadna jadranska struja (WAC) nosi duž zapadnog Jadrana vodu bogatu hranjivim tvarima iz
talijanskih rijeka na sjeveru. PodruÄje pogoÄeno dotokom rijeke Po pokazalo je maksimum koncentracije klorofila i duÅ”ika unutar rijeka. Å toviÅ”e, u jugozapadnom Jadranu koliÄina hranjivih tvari i
organske tvari je povezana s tvarima koje dolaze iz sjevernih talijanskih rijeka (uglavnom rijeke po).
SliÄno tome, u jugoistoÄnom dijelu jadranskog mora, dotok rijeke Bune / Bojane sadržavao je relativno visoke vrijednosti klorofila na nivou regionalne distribucije. Tri podruÄja su izravno ili
neizravno povezana s dinamikom rijeÄnih perjanica, te organskim i anorganskim rijeÄnim unosom koji odreÄuje trofiÄko stanje podruÄja. Konkretno, jugoistoÄno Jadransko more je mezo-eutrofiÄno podruÄje; unatoÄ veÄoj istoÄnoj strani Jadrana koij je bio oligotrofan bazen
