PURPOSE The molecular profile of Pararhadinorhynchus magnus Ha, Amin, Ngo, Heckmann, 2018 described from Scatophagus argus (Linn.) off Haiphong in the Gulf of Tonkin, Pacific Ocean, Vietnam is provided for the first time. It was morphologically distinguished from the South Australian species, Pararhadinorhynchus mugilis Johnston and Edmonds, 1947 and Pararhadinorhynchus coorongensis Edmonds, 1973 from mullets. Two other species of Pararhadinorhynchus are also recognized Pararhadinorhynchus upenei Wang, Wang, Wu, 1993 from China and Pararhadinorhynchus sodwanensis Lisitsyna, Kudlai, Cribb and Smit, 2019 from South Africa. The assignment of Diplosentis manteri Gupta and Fatma, 1980 to Pararhadinorhynchus is not recognized. METHODS Sequences of the 18S, small internal transcribed spacers (ITS1-5.8S-ITS2) and 28S from nuclear DNA were generated to molecularly characterize P. magnus. The phylogenetic analyses were achieved by comparison of the 18S and ITS1-5.8S-ITS2 region only as the 28S amplified a short region (425-428 bp) that was not sufficient for the present study. RESULTS Phylogenetic analyses showed that P. magnus and the other species of Pararhadinorhynchus sequenced were nested within separate clades in the case of 18S gene and suggesting that these species do not share a common ancestor. In contrast, the ITS1-5.8S-ITS2 region shows a close arrangement of species of Pararhadinorhynchus with molecular affinities to the family Diplosentidae, suggesting that final placement of these species in Transvenidae needs further study and revision. CONCLUSIONS The molecular data from the present study will provide further comparative insights into species of Pararhadinorhynchus and its close affiliation to other acanthocephalan species and genera from different geographical areas.The branching of blood vessels around the heart is varied in each animal. Three branching patterns of the brachiocephalic trunk in cats have been reported. However, supra-aortic arteries in the hearts of cats have never been investigated. In this study, we hypothesized that the variations of the aortic arch, supra-aortic arteries, and vena cava were observed in domestic cats. Sixty-one hearts obtained from the cadavers of domestic cats (Felis catus) were analyzed in terms of anatomical characteristics, size, and the length of these supra-aortic vessels by using a 3D scanner. New variations of the left and right subclavian arteries were observed using the location of the internal thoracic (ITA) and vertebral artery (VA) as the criterion to group the varying patterns. We found four patterns of the left subclavian artery, which included ITA budding contralateral before VA (5%), VA budding opposite to ITA (75%), VA budding contralateral before ITA (13%) and ITA budding ipsilateral before VA (7%). learn more In contrast, only three patterns were found in the right subclavian artery, which included VA budding opposite to ITA (20%), VA budding contralateral before ITA (19%), and ITA budding contralateral before VA (61%). Moreover, although an average vascular diameter in male cats was higher than in female subjects, the supra-aortic blood volume in both sexes was not different. The findings of this study could help fill the existing gap of knowledge on the anatomical variations of supra-aortic arteries in cats and could be used in clinical applications based on relevant anatomical data.Transfusion-associated iron overload may lead to increased risk of infection, but its role in myelofibrosis (MF) has been scarcely explored. We evaluated 106 consecutive patients with primary or secondary MF. Up to 38% of patients were transfusion-dependent (TD) with a median of 14 RBC units received. Median observation time was 36 months (range 3-203). Forty-five percent of patients experienced one or more infectious episodes for a total of 69 infectious events, 13 (19%) of which were severe. The 60-month cumulative incidence of infection was 64.1 ± 6.5%. TD patients showed a higher incidence of infection (HR = 2.13, p = 0.019). Transfusion burden was markedly greater in TD patients with infectious complication (median 24 RBC units vs 15 RBC units; p = 0.012). The 60-month overall survival was 40 ± 5.9%. Lower International Prognostic Scoring System (IPSS) risk (p  less then  0.0001) and ruxolitinib (p = 0.027) were significantly correlated with higher survival. This real-world study showed increased infections in patients with higher transfusion burden. It may therefore be interesting to further investigate the role of iron chelation in improving infection-free survival in MF patients.Immunoglobulin light chain amyloidosis (AL) is a plasma cell disorder characterized by accumulation of misfolded proteins, which can induce organ damage. Venetoclax is active in multiple myeloma patients, in particular those with t(11;14) translocation. t(11;14) translocation is the most common cytogenetic abnormality in AL patients; venetoclax may thus be a useful additional treatment option for this disease. However, a recent trial in multiple myeloma patients (BELLINI) reported increased mortality associated with venetoclax versus placebo in combination with bortezomib and dexamethasone. In this report, we describe an AL patient who had suffered from recurrent infection during previous treatment, but who responded to and tolerated well single-agent venetoclax for more than 1 year. The present report indicates that venetoclax monotherapy may be active and safe for refractory AL amyloidosis.Neuroinflammation and demyelination are hallmarks of several neurological disorders such as multiple sclerosis and multiple system atrophy. To better understand the underlying mechanisms of de- and regeneration in respective diseases, it is critical to identify factors modulating these processes. One candidate factor is alpha-Synuclein (aSyn), which is known to be involved in the pathology of various neurodegenerative diseases. Recently, we have shown that aSyn is involved in the modulation of peripheral immune responses during acute neuroinflammatory processes. In the present study, the effect of aSyn deficiency on de- and regenerative events in the CNS was analyzed by using two different demyelinating animal models chronic MOG35-55-induced experimental autoimmune encephalomyelitis (EAE) and the cuprizone model. Histopathological analysis of spinal cord cross sections 8 weeks after EAE induction revealed a significant reduction of CNS inflammation accompanied by decreased myelin loss during late-stage inflammatory demyelination in aSyn-deficient mice.
