UNLABELLED Fusarium culmorum is a ubiquitous soil-borne fungus able to cause foot and root rot and Fusarium head blight on different small-grain cereals, in particular wheat and barley. It causes significant yield and quality losses and results in contamination of the grain with mycotoxins. This review summarizes recent research activities related to F.(More)
The present study demonstrates the in vitro effectiveness of the macrolide rokitamycin and the phenothiazine compound chlorpromazine against Acanthamoeba castellanii. Growth curve evaluations revealed that both drugs inhibit trophozoite growth in dose- and time-dependent ways. The effects of both drugs when they were used at the MICs at which 100% of(More)
BACKGROUND Human papillomavirus 16 infection has been proven to be associated with oropharyngeal squamous cell carcinomas (SCCs) and is probably the main reason of the reported increase in the incidence. The role of high-risk (HR) HPV for carcinogenesis of other sites in the head and neck awaits confirmation. With the aim to evaluate the prevalence of HPV(More)
OBJECTIVE To examine the relationship between circulating interleukin-10 (IL-10) and the occurrence of lymphocyte apoptosis after surgical/anesthesia trauma. METHODS Data were collected prospectively on 18 adult patients undergoing elective major surgery. Blood sampling for assessment of lymphocyte apoptosis and IL-10 levels was performed on the day(More)
In 67 patients submitted to surgical procedures serum neopterin (NPT) and Interleukin 2 soluble receptors (IL2R) were evaluated at the end of the operation as well as 24, 48, 72 hours later. Thirty seven of the subjects (Group B) had undergone minor surgery (average time of operation: 40 +/- 10 min.), thirty (Group A) had undergone major surgery (average(More)
BACKGROUND Surgery and anesthesia cause depression of cell-mediated immunity in the postoperative period, including a reduction in the numbers of circulating lymphocytes. It has been claimed that this immunosuppression is associated with an increased incidence of postoperative infections. HYPOTHESIS Lymphocytopenia following surgical trauma depends on a(More)
This work was undertaken to determine whether Acanthamoeba could play a role in the survival and transmission of coxsackieviruses and focused on in vitro interactions between Acanthamoeba castellanii and coxsackie B3 viruses (CVB-3). Residual virus titer evaluations and immunofluorescence experiments revealed a remarkable CVB-3 adsorption on amoeba surfaces(More)
We have identified and sequenced a cDNA clone coding for Trichomonas vaginalis alpha-actinin. Analysis of the obtained sequence revealed that the 2,857-nucleotide-long cDNA contained an open reading frame encoding 849 amino acids which showed consistent homology with alpha-actinins of different species. Such homology was particularly significant in regions(More)
The presence of enterobacterial repetitive intergenic consensus (ERIC) sequences was demonstrated for the first time in the genome of Mycobacterium tuberculosis; these sequences have been found in transcribed regions of the chromosomes of gram-negative bacteria. In this study genetic diversity among clinical isolates of M. tuberculosis was determined by PCR(More)
We report preventive measures adopted after tuberculosis(TB) transmission from a nurse to a newborn assessed in late July 2011. All exposed neonates born between January and July 2011 were clinically evaluated and tested by QuantiFERON TB gold in-tube; newborns testing positive were referred for prophylaxis.Of 1,340 newborns, 118 (9%) tested positive and no(More)
