Cervico-Facial Actinomycosis: Epidemiological and clinical comments

2008

In a retrospective investigation performed in the department of Surgical Odontostomatology of Palermo University Polyclinic from 1997-2006, the authors examined 12 cases of cervico-facial actinomycosis, taking into consideration age range, gender distribution, predisposing factors and symptoms. In concordance with reports in literature, they found that the disease was perimandibular in 65%, they also report the diagnostic methods and therapeutic approaches used in the study

Two Patients With History of STEC-HUS, Posttransplant Recurrence and Complement Gene Mutations

2013

Hemolytic uremic syndrome (HUS) is a disease of microangiopathic hemolytic anemia, thrombocytopenia and acute renal failure. About 90% of cases are secondary to infections by Escherichia coli strains producing Shiga-like toxins (STEC-HUS), while 10% are associated with mutations in genes encoding proteins of complement system (aHUS). We describe two patients with a clinical history of STEC-HUS, who developed end-stage renal disease (ESRD) soon after disease onset. They received a kidney transplant but lost the graft for HUS recurrence, a complication more commonly observed in aHUS. Before planning a second renal transplantation, the two patients underwent genetic screening for aHUS-associat…

Identification and study of a Candida albicans protein homologous to Saccharomyces cerevisiae Ssr1p, an internal cell-wall protein

2003

After screening of aCandida albicansgenome database, the product of an ORF (IPF 3054) that has 62 % homology withSaccharomyces cerevisiaeSsr1p, an internal cell-wall protein, was identified and named CaSsr1p. The deduced amino acid sequence shows that CaSsr1p contains an N-terminal hydrophobic signal peptide, is rich in Ser and Thr amino acids and has a potential glycosylphosphatidylinositol-attachment signal. CaSsr1p is released following degradation of isolated cell walls by zymolyase (mainly a 1,3-β-glucanase) and therefore seems to be covalently linked to theβ-glucan of the cell walls. Both disruption and overexpression of theCaSSR1gene caused an increased sensitivity to calcofluor whit…

Epidemiology of intensive care unit-acquired sepsis in Italy: Results of the SPIN-UTI network

2018

Background. Sepsis is the major cause of mortality from any infectious disease worldwide. Sepsis may be the result of a healthcare associated infection (HAI): the most frequent adverse events during care delivery especially in Intensive Care Units (ICUs). The main aim of the present study was to describe the epidemiology of ICU-acquired sepsis and related outcomes among patients enrolled in the framework of the Italian Nosocomial Infections Surveillance in ICUs - SPIN-UTI project. Study design. Prospective multicenter study. Methods. The SPIN-UTI network adopted the European protocols for patient-based HAI surveillance. Results. During the five editions of the SPIN-UTI project, from 2008 to…

Pesticide analysis in coffee leaves using a quick, easy, cheap, effective, rugged and safe approach and liquid chromatography tandem mass spectrometr…

2017

An analytical method using a quick, easy, cheap, effective, rugged and safe (QuEChERS) procedure for multi-residue determination of 52 pesticides in coffee leaf extractshas been developed and validated according to SANTE/11945/2015 guidelines. Different sorbent combinations for dispersive solid phase extraction (d-SPE) clean-up as well as dispersive liquid-liquid microextraction (DLLME) were tested. The relative standard deviations (RSDs) for the recovery of 87-94% of pesticides added to coffee leaf extracts,was ≤20% for samples spiked at concentrations up to 50ng*g-1 depending on the clean-up procedures. However, samples spiked with a 100ng*g-1 pesticide mixture gave RSDs>20% for most pest…

Bacterial 2,3-butanediol dehydrogenases

1978

Enterobacter aerogenes, Aeromonas hydrophila, Serratia marcescens and Staphylococcus aureus possessing L(+)-butanediol dehydrogenase produced mainly meso-butanediol and small amounts of optically active butanediol; Acetobacter suboxydans, Bacillus polymyxa and Erwinia carotovora containing D(-)-butanediol dehydrogenase produced more optically active butanediol than meso-butanediol. Resting and growing cells of these organisms oxidezed only one enantiomer of racemic butanediol. The D(-)-butanediol dehydrogenase from Bacillus polymyxa was partially purified (30-fold) with a specific activity of 24.5. Except NAD and NADH no other cofactors were required. Optimum pH-values for oxidation and red…

Efficient synthesis and 5-LOX/COX-inhibitory activity of some 3-hydroxybenzo[b]thiophene-2-carboxylic acid derivatives

2012

Abstract A series of 3-hydroxybenzo[ b ]thiophene-2-carboxylic acid derivatives has been prepared and subsequently evaluated with regards to the inhibition of 5-LOX/COX. Structure optimization furnished derivatives with promising in vitro activity as dual 5-LOX/COX inhibitors with submicromolar IC 50 values for inhibition of 5-LOX and COX-1, respectively.

Reusing coffee ground waste in manufacture of novel sustainable product

2021

Coffee is one of the most important commodities in the world. Every year the coffee industry is responsible for generating a large amount of wastes, mainly Spent Coffee Grounds (SCGs). The traditional disposal of this residue into the environment should be avoided due to its toxicity and organic character. Because of the decrease in nonrenewable natural resources, society has been making a huge effort to valorize and reuse several types of wastes in the production of novel sustainable products. In this regard, construction is considered one of the most energy-intensive sectors. As a consequence, the goals of sustainability and energy efficiency must be prosecuted to achieve the results expe…
