Varicella notification in immigrants: a brief report from Ferrara, Italy
No full textBackground and Aim of the work - We conducted a survey of varicella cases' notifications in the immigrant population in the province of Ferrara, Italy.

Materials and Methods – We collected notifications of infectious disease between 2002 and 2006. 

Results and discussion - At the end of 2006, the 4.5% (14252 subjects) of total population of the province of Ferrara and its province was represented of immigrants from foreign countries. In this context, between 2002 and 2006, a total of 1969 cases of varicella, including 3.1% related to migrants, were reported. Among immigrants, there were 36 cases in males, and 26 in females. The cases were notified in the 64.5% by the hospital emergency service, in the 16.1% by the paediatrician and in 19.4% by the general practitioner. The incidence appears similar in both populations in childhood: this fact could means an integration in the local epidemiology for varicella of the immigrant school-children.

Internal polarized gas targets: systematic studies on intensity and correlated effects
No full textThe work carried out during the PhD was dedicated to the study of high-density polarized
gas targets used in high-energy physics. The thesis is related to the PAX experiment,
which aims to produce a beam of polarized anti-protons, by means of spin-filtering with a
polarized atomic target. In order to obtain the densities required by high-energy particle
physic, gaseous targets are a combination of an Atomic Beam Source and a storage cell.
The possibility to improve the various components of the ABS and the storage cell has been
evaluated, through dedicated systematic studies, using the facilities available in “Spinlab”
of Universit´a di Ferrara.
The attenuation of a collimated beam passing through the rest gas of a vacuum system
has been studied; different nozzle geometries have been tested (comparing the measured
data with the data calculated by simulation programs); design and tests of an new kind
of injection tube with internal fins (with the aim of decreasing the conductance of the
storage cell without diminishing the acceptance and thus to increase the integrated target
thickness).
Estimation of the attenuation coefficients and total cross sections have been derived from
the measurements of the attenuation of a hydrogen or deuterium beam. This quantities
are important for projecting new ABS and to improve the existing ones. A favorable
nozzle geometry (called “trumpet”) that increases the beam intensity has been derived
from simulations and experimental tests. Tests on the injection tubes with fins did not
give positive results when applied to the PAX storage cell geometry; however a azimuthal
motion of the atoms of a focused beam emerged from the measurements, a motion that
until now has been completely neglected

Amazonian plants from ethnomedicine to biotechnology through pharmaceutical biology approaches: a PhD experience in connecting forest with laboratory
No full textThe South american Natives, Shuar and Achuar people and their ethnomedical culture constitute the
background subject of the Phd research, performed both in Ecuador (Salesian Politechnic University,
Quito), and in Italy (Pharmaceutical biology labs, University of Ferrara). Based on ethnomedical
responses, Piper aduncum, Maytenus macrocarpa, Schinus molle, Tecoma stans and Eugenia hallii were
chosen as amazonian plant species subject of the research.
AIMS
The research has been focused on:
− checking the presence of endophytic fungi in plants;
− isolating and subculturing pure endophytic strains;
− checking the biotransformation capacity of the isolated endophytes on pure compounds; the most
performing endophytes were also tested on phytocomplexes and pure chemicals obtained by the
plant from which the fungi were isolated;
− phytochemical characterization and bioactivity assays of plant extracts: P. aduncum.

METHODS
Biotransformations. Fresh aerial plant parts were properly washed in sanitizing solutions and in vitro
cultured using adequate solid media to isolate endophytes. (+/-)-cis-bicyclo[3.2.0]hept-2-en-6-one,
acetophenone, 1-indanone, 2-furyl methyl ketone, 2-methylcyclopentanone, 2-methylcyclohexanone, 2-
methoxycyclohexanone were chosen as substrate model for biotransformations. The cultures were
sampled after 1, 3, 7, 10 days of culturing, and ethyl acetate extracted to verify by GC-MS the presence of
possible biotransformation products. Biotransformations were also checked on P. aduncum whole
essential oil and on dillapiol, cis-ocimene, piperitone, (-)-terpinen-4-ol as most abundant chemicals.
Chemical fingerprinting of P. aduncum essential oil. Steam distillation was adopted to obtain the essential
oil, then characterized by GC-MS, NMR analyses.
In vitro bioassays of P. aduncum essential oil. Antimicrobial activities were checked in vitro using proper
agarized media to reach MIC. Antioxidant capacities were checked through DPPH test, ABTS and
photochemiluminescence assays. Born's turbidimetric method and Writhing test were respectively
adopted to check platelet-aggregation and anti-nociceptive properties. Mutagenic, antimutagenic
properties and toxicity were assayed using classical and modified Ames test.
MAIN RESULTS
364 fungal strains were in vitro isolated. Among all, 5 strains performed biotransformations on
acetophenone to (S)-1-phenylethanol, with important yields (78-97%) and enantiomeric excess (78-
100%). Three strains gave also phenols probably by enzymatic reactions (Baeyer-Villiger oxidations). 15
fungal strains gave the lactones (-)-(1S,5R)-2-oxabicyclo[3.3.0]oct-6-en-3-one and (-)-(1R,5S)-3-
oxabicyclo[3.3.0]oct-6-en-2-one from (+/-)-cis-bicyclo[3.2.0]hept-2-en-6-one, probably as result of
monooxygenase activation. Phytochemical characterization of P. aduncum essential oil has evidenced
dillapiol as the most abundant terpene, followed by cis-ocimene, piperitone and terpinen-4-ol. Only cisocimene
and piperitone gave several biotransformation products through dehydrogenation and
hydroxylation reactions. The essential oil has evidenced non-mutagenic properties and interesting
antifungal and antioxidant activities.
CONCLUSIONS
Several endophytic fungal strains from Amazonian plants were isolated and checked for
biotransformations on pure chemicals and on P. aduncum essential oil. Data obtained will be useful for
possible following patents about micro-organisms able to transform pharmaceutically interesting
chemicals. Taxonomical characterization of the most performing fungal strains is still in progress. P.
aduncum essential oil can be considered genotoxically safe and provides interesting antifungal and
antioxidant properties, supporting its ethnomedical use as cicatrising and disinfectant crude drug and
suggesting an extension of its employ as preservative ingredient
