RESUMO

Minute virus of canines (MVC) belongs to the family Parvoviridae, genus Bocaparvovirus, and has been mainly described during enteritis episodes in young dogs. This study reports the characterization of four divergent MVC strains detected between 2012 and 2018, three of which were from dogs illegally imported into Italy, most probably from Eastern Europe, that cluster together phylogenetically but share low genetic similarity with the fourth MVC from an autochthonous dog and other available MVC sequences. Our data indicate that the introduction of genetically distinct MVC strains occurred through the illegal movement of dogs from a geographic area where a distinct MVC lineage was most likely circulating. Enforced surveillance of MVC in the dog population of Eastern Europe and its neighboring countries may shed light on, and eventually trace back to, illegal animal movements.

RESUMO

Protein kinase CK2 sustains acute myeloid leukemia cell growth, but its role in leukemia stem cells is largely unknown. Here, we discovered that the CK2 catalytic α and regulatory ß subunits are consistently expressed in leukemia stem cells isolated from acute myeloid leukemia patients and cell lines. CK2 inactivation with the selective inhibitor CX-4945 or RNA interference induced an accumulation of leukemia stem cells in the late S-G2-M phases of the cell cycle and triggered late-onset apoptosis. As a result, leukemia stem cells displayed an increased sensitivity to the chemotherapeutic agent doxorubicin. From a molecular standpoint, CK2 blockade was associated with a downmodulation of the stem cell-regulating protein BMI-1 and a marked impairment of AKT, nuclear factor-κB (NF-κB) and signal transducer and activator of transcription 3 (STAT3) activation, whereas FOXO3a nuclear activity was induced. Notably, combined CK2 and either NF-κB or STAT3 inhibition resulted in a superior cytotoxic effect on leukemia stem cells. This study suggests that CK2 blockade could be a rational approach to minimize the persistence of residual leukemia cells.

RESUMO

AIM: The uroflowmetry data of a selected number of patients who took part to the QUIBUS study (366 traces selected after quality control by a central panel of reviewer) were evaluated for their relationships with age, prostate volume, and IPSS and ICS-BPH scores. Waiting time, flow time, voided volume, maximum flow rate (Q(max)) and average flow rate (Q(ave)) were the flow variables considered for analysis. Only measurements with total voided volume exceeding 100 ml were included. RESULTS: An increasing percentage of subjects with voided volume <200 ml was observed over 65 years of age. Age did not affect neither Q(ave) nor Q(max )(p = n.s. at correlation analysis). In particular, Q(max)was <15 ml/s in about 70% of patients independently of age. Prostate enlargement was inversely associated with voided volume, Q(max) and Q(ave), showing a worsening of urinary function for increasing values of prostate volume Q(max) was negatively correlated with IPSS total score and with most single items with the exception of two storage symptoms such as repeated urination and nocturia). Accordingly, Q(max) was inversely associated with the total score ICS-BPH for voiding symptoms to a higher extent (r = -0.31, p < 0.01) than with the one for storage symptoms (r = -0.22, p < 0.01). Flow variables were inversely correlated with IPSS-QoL. CONCLUSION: Uroflowmetry and IPSS, although not allowing a definitive diagnosis of obstruction, may nonetheless satisfy the clinical need of a rapid, easy and accurate tool for the noninvasive screening of LUTS patients.
