PHENOLOGICAL AND MORPHOLOGICAL STUDIES OF PISTACIA TEREBINTHUS L. GENOTYPES NATIVE OF BULGARIA WITH DIFFERENT ASSET OF TREE SEXUALITY

2009

The genus Pistacia is a dioecious species staminate and pistillate inflorescences born on different trees and are wind pollinated. In pistachio orchards, female and male flowering periods are often not synchronized. In fact, male trees spread their pollen before the flowers of female trees become receptive. Pollination is commonly devoted to spontaneous males of P. terebinthus. In this research authors refer to the results obtained observing the phenology of the blooming period of monoicous genotypes of P. terebinthus discovered in the Rhodope Mountains (Bulgaria). In some selected trees phenological stages have been observed in situ. The blooming date is influenced by local environmental c…

A new species of Ferula (Apiaceae) from Malta

2018

Ferula melitensis, a new species from the Malta Archipelago, is described and illustrated. It belongs to the taxonomic group of F. communis, showing close relationships mainly with F. tunetana, F. arrigonii, F. communis s.str. and F. glauca, from which it differs in several features regarding the stem, leaves (mainly for shape and size of terminal segments), flowers and mericarps; other significant differences regard the ecology and phenology. The investigations, carried out on living plants, herbarium material and literature data, regard the morphological analysis of vegetative and reproductive structures, the anatomy of terminal leaf segments and mericarps, as well as the shape and size o…

Chronic toxicity of methylparathion to the rotifer Brachionus calyciflorus fed on Nannochloris oculata and Chlorella pyrenoidosa

1993

The effect of sublethal levels of methylparathion (0,1, 3, 5, 7 mg 1−1) on the freshwater rotifer, Brachionus calyciflorus, during their entire life cycle was studied. Rotifers were fed on two species of unicellular algae: Nannochloris oculata and Chlorella pyrenoidosa; both algal concentrations were 5 × 105 cell ml−1.

The gut microbiota instructs the hepatic endothelial cell transcriptome

2021

Summary The gut microbiota affects remote organ functions but its impact on organotypic endothelial cell (EC) transcriptomes remains unexplored. The liver endothelium encounters microbiota-derived signals and metabolites via the portal circulation. To pinpoint how gut commensals affect the hepatic sinusoidal endothelium, a magnetic cell sorting protocol, combined with fluorescence-activated cell sorting, was used to isolate hepatic sinusoidal ECs from germ-free (GF) and conventionally raised (CONV-R) mice for transcriptome analysis by RNA sequencing. This resulted in a comprehensive map of microbiota-regulated hepatic EC-specific transcriptome profiles. Gene Ontology analysis revealed that …

A new species of Anthemis sect. Hiorthia (Asteraceae) from SE Sicily

2013

A new species of Anthemis sect. Hiorthia (Asteraceae) is described from Sicily. This taxon, named A. piagnattiorum, is confined to a restricted area of the Hyblaean territory (SE Sicily), in the Natural Reserve of Cava Grande (Cassibile, Siracuse), where it takes shelter on carbonate rocky habitat and participates, with other Sicilian endemic taxa, to the composition of a termophilous chasmophytic community (Putorio calabricae–Micromerietum microphyllae).

The vascular flora of Nature Reserve “Pizzo Cane, Pizzo Trigna and Grotta Mazzamuto” (NW Sicily)

2009

A floristic investigation was carried out in “Pizzo Cane, Pizzo Trigna and Grotta Mazzamuto” Nature Reserve, one of the largest in Sicily. In spite of the considerable botanical interest of this area, few data were available from classic and recent literature. Based on field investigations, coupled with bibliographic and herbarium researches, we have listed 951 infrageneric taxa belonging to 103 families and 446 genera. A lot of these entities are reported in this area for the first time, for others ancient records are confirmed. Life form analysis shows the dominance of therophytes (44,79%) and hemicryptophytes (27,77%). From a chorological point of view, Mediterranean elements show a grea…

Vascular complications following bladder drained, simultaneous pancreas-kidney transplantation: the University of Miami experience

2000

Vascular complications remain a significant nonimmunologic source of pancreas allograft loss. From February 1993 through January 1998, we performed 98 simultaneous pancreas-kidney transplantations (SPK) using pancreatic exocrine bladder drainage in patients with type 1 insulin-dependent diabetes mellitus and end-stage renal disease. They originally received quadruple immunosuppression, and since May 1997 triple immunosuppression protocol (tacrolimus, mycophenolate mofetil, and steroids). The patients' mean age was 37 years (range 24-53 years), including 50 women and 48 men with a mean follow-up of 42 months. The overall rate of vascular complications was 6% (5 patients). The vascular compli…
