Evidence of diagnostic enhancement pattern in hepatocellular carcinoma nodules ≤2 cm according to the AASLD/EASL revised criteria
No full textPurpose: To define the percentage of small (£2 cm)
hepatocellular carcinoma (HCC) nodules showing the
diagnostic enhancement pattern at CEUS, computed
tomography (CT), and gadobenate dimeglumine (Gd-
BOPTA)—enhanced magnetic resonance (MR) imaging.
Methods: 42 cirrhotic patients (26 male, 16 female;
67 ± 12 years) with 46 biopsy-proven HCCs £2 cm were
included. Each HCC was scanned by CEUS, contrastenhanced
CT, and Gd-BOPTA-enhanced MR imaging.
Nodule enhancement was evaluated by two readers.
Independent analysis was followed by consensual analysis
and the proportion of HCCs with the diagnostic
enhancement pattern (nodule hyperenhancing on hepatic
arterial phase and hypoenhancing on portal venous—late
phase) on CEUS, CT, and MR imaging was compared
by chi-square test.
Results: Very good inter-reader agreement was observed
on hepatic arterial phase and portal venous—late phase:
CEUS, k = 0.89 and 0.85; CT, k = 0.91 and 0.88; MR
imaging, k = 0.96 and 0.94. CEUS and CT did not
differ in the percentage of HCC nodules with a diagnostic
enhancement pattern (18/46 and 16/46; P = 0.66),
while MR imaging revealed the diagnostic pattern in
higher percentage of nodules (29/46; P = 0.012) in
comparison to CEUS and CT.
Conclusions: CEUS and contrast-enhanced CT did not
differ in the percentage of small HCC nodules with
diagnostic enhancement pattern, while Gd-BOPTAenhanced
MR imaging revealed the diagnostic pattern
in a higher nodule number in comparison to CEUS and
CT
Attività antagonistica, in vitro, di Bacillus velezensis nei confronti di funghi responsabili del "Mal del piede" dei cereali
No full textOne of the most dangerous durum wheat diseases in Southern Italy is foot rot and root rot
complex. Soil borne durum wheat pathogens as Bipolaris sorokiniana, Fusarium
acuminatum, F. avenaceum, F. compactum, F. crookwellense, F. culmorum, F. graminearum,
sambucinum, Microdochium nivale, Rhizoctonia cerealis are difficult to control because
they are not readily identifiable, and above all, because they survive, for many years, without
their hosts, in the soil through durable spores. Environmental pollution due to agrochemicals
and food safety had led to demanding alternatives to diseases chemical control. For an
environmental friendly control, interesting application prospects are the use of
microorganisms. This study was conducted to evaluate the antagonistic activity, invitro, of
Bacillus velezensis against B. sorokiniana, F. culmorum, F. sambucinum and R. cerealis,
same of the most dangerous pathogens responsible of foot root and root rot complex, in
Sicily
