BRYOFLORISTICAL DATA FROM THE APUSENI MOUNTAINS (ROMANIAN WESTERN CARPATHIANS, TRANSILVANIA)

The main aim of this study was to explore the bryophyte diversity and distribution patterns in the Apuseni Mountains. From our collections hitherto 108 bryophyte species were identified. The 31 Marchantiophyta and 77 Bryophyta species belong to 74 genera of 40 families. Among them the endangered Campylium protensum, Didymodon cordatus and the critically endangered Ditrichum gracile and Schistidium robustum are to be mentioned

Vertical mandibular bone augmentation by the osteodistraction of the transplanted fibula free flap: A case series with long-term follow-up

Vertical augmentation of the mandible to prepare dental implant therapy is still a challenge, especially with large mandible defects. Reconstruction with fibula free flap is a regularly applied approach in such cases, but it does not always yield optimal results: the resulting crestal height might differ significantly from the crestal height of the patient's intact bone, which makes esthetic and functional rehabilitation difficult. Osteodistraction of the integrated flap is a known but rarely discussed approach where the already integrated flap undergoes additional distraction. Through the four cases reported here, we would like to demonstrate that the osteodistraction of the transplanted fibula free flap is a useful and efficient method of secondary augmentation for cases where the flap itself fails to produce the desired crestal height, and no other method is applicable. The cases show that the method allows outcomes that are highly satisfactory, both in the functional and esthetic sense

Fánlakó, korhadék- és talajlakó növény- és állatközösségek kapcsolata trópusi esőerdőkben. = Connection of epiphytic, lignicolous and terricolous plant and animal communities in tropical rain forests.

A kutatás célja a trópusi esőerdők epifiton és korhadéklakó virágtalan növény - gerinctelen állat közösségeinek vizsgálata volt, egyrészt a közösségek vertikális eloszlása (korona és más áglakó, levéllakó, kéreglakó, korhadéklakó) másrészt az egyes szintekben a növény és állatkomponens összetétele, biodiverzitása, egymáshoz való korrelációja szempontjából. A cél elérése érdekében, a megfelelő logisztikiai előkészítés után a közös botanikus-zoológus team két gyűjtő és kutató expedíciót szervezett, egyiket 2003-ban Hispaniola szigetére, a Dominikai Köztársaságba, a központi hegyvonulat erdeibe, másikat pedig a Venezuelai Andok esőerdeibe és páramo vegetációjába Méridától a Karib tengerig. Az expedíciók eredménye 3400 virágtalan növény- és legalább ugyanennyi gerinctelen állatpéldány, valamint 150 futtatott moha, korhadék és avarminta begyűjtése volt. Különös hangsúlyt helyeztünk a májmoha, lombosmoha, zuzmó, páncélos és korongatka, ugrópók, álkérész és földigiliszta anyag begyűjtésére, amelyeket saját szakembereink dolgoznak fel. A begyűjtött anyag taxonómiai feldolgozása folyik és eddig mintegy 20 tudományra nézve új faj leírása, számos az érintett területekre nézve új faj meghatározása történt meg. Az anyag legalább részleges rendszertani feldolgozását követi az a komplex munka, a mely a célkitűzésben megadott szintezettség és korreláció megállapítását teszi lehetővé. | The aim of the research was the analysis of the epiphytic (canopy and other branch, leaf and bark inhabiting) and lignicolous cryptogamic plant - invertebrate animal communities, investigating first their vertical stratification and second their horizontal correlation between plant and animal components. To achieve these goals, after the necessary logistical preparations, a joint botanist-zoologist team organized two collecting and research expeditions. One in 2003 in the forests of the central mountain range of the Dominican Republic and one in 2005 to the montane forests of the Venezuelan Andes, from Mérida to the Caribbean coast. As a result, 3400 cryptogamic plant and even more invertebrate animal specimens and in addition, for further extraction, some 150 moss, litter and other samples were collected. Special emphasis was laid on the collection of Bryophyta, Hepaticophyta, Acari (Oribatidae and Uropodina), Areneae (Salticidae) and Lumbricidae, as the identification of these groups can be carried out by our own staff. During the identification of the collected material hitherto some 20 species were described as new to science and many more identified specimens proved to be new to the given area. Further important results are expected during the continuation of complex work, especially in the field of the stratification and of the correlation of the plant and animal communities

Esthetic and functional reconstruction of large mandibular defects using free fibula flap and implant-retained prosthetics - a case series with long-term follow-up

The reconstructive and rehabilitative management of large mandibular defects with basal continuity is challenging in many respects, especially in the vertical dimension. The free fibula flap is an under-utilised but efficient approach in this indication. The aim of this case series is to demonstrate its use and long-term success.Three cases are presented, where the patient had a large bone defect (at least 5 cm in length and 1 cm in the vertical dimension), but the continuity of the mandible was maintained. Two cases were related to pathological fracture and one was a large defect due to oncological surgery. Vertical augmentation with free microvascularised fibula flap was carried out, followed by implant-retained prosthetic therapy. Clinical status has been followed up for 5 to 6 years, with special attention to the condition of the peri-implant tissues and any radiographically detectable alterations or complications. No complications occurred during the follow-up. Function and esthetics have remained unchanged throughout.Free microvascularised fibula flap reconstruction combined with implant-retained prosthetics allows a lasting functional and esthetic solution in the discussed indication

BRYOFLORISTICAL DATA FROM THE APUSENI MOUNTAINS (ROMANIAN WESTERN CARPATHIANS, TRANSILVANIA) 2.

The main aim of this study was to explore the bryophyte diversity and distribution patterns in the Apuseni Mountains. From our collections hitherto 94 bryophyte species were identified. The 25 Marchantiophyta and 69 Bryophyta species belong to 73 genera of 42 families. Syntrichia norvegica are new for the whole Apuseni Mountains. Among them the endangered Campylium protensum, the near threatened Barbula crocea, Platydictya jungermannioides and the very rare Abietinella abietina var. hystricosa are worth to be mentioned
