Powell (1966: 91).</p> <p>Unconfirmed fossil reports:</p> <p> <i>Leptadrillia loria</i> Bartsch, 1934: Perrilliat (1973: 53, pl. 25, figs. 3–6).</p> <p> <b>Type material.</b> Holotype 6.8 x 2.3 mm (USNM 430701).</p> <p> <b>Type locality.</b> R/V <i>Caroline</i> Sta. 106, off the N coast of Puerto Rico, between 18°3l'20"N, 66°16'30"W, and 18°31'30"N, 66°18'20"W, in 150–195 fms [274–357 m].</p> <p> <b>Range.</b> Known only from the holotype. Reported from 274– 357 m.</p> <p> <b> Description. <i>Shell</i></b> very small (6.8 mm), narrowly fusiform (W/L = 0.338), glossy, translucent; whorls convex, number to 8½, the last approximately 60% of the total length; axial sculpture predominant; aperture narrow; anterior canal moderately long. <i>Protoconch</i> of 1½–1¾ smooth, translucent whorls, first expands rapidly such that the apex is lopsided. <i>Axial sculpture</i> of slightly curved, narrow ribs that run from suture-to-suture, 10 on the penultimate, 10 the body whorl to the varix, peripheries below mid-whorl that are recurved in the sulcus, and sigmoid last whorl where they end at the anterior fasciole; crests round, not ridged. Ribs on first teleoconch whorl angular, almost knob-like. Rib interspaces vary ½–2 time the width of ribs. Growth striae faint, cross ribs diagonally and recurved on whorl shoulder. <i>Varix</i> rib-like but straighter, larger, not curved at twice the width of previous ribs, positioned well behind the anal sinus, about ¼–⅓-turn from the edge of the outer lip. <i>Spiral sculpture</i> is absent except for spiral threads on the anterior fasciole. <i>Sulcus</i> obscure but marked by lower, recurved ribs and curved growth striae. <i>Outer lip</i> thin, translucent, occasionally strengthened by clusters of heavy growth striae or weak folds. Swelling along suture of outer lip indicate previous positions of the parietal lobe. Lip edge forms an arc from and congruent with anal sinus to the stromboid notch; edge of lip bends in toward aperture and outward at anal sinus. Stromboid notch shallow. <i>Anal sinus</i> deep, U-shaped; entrance not constricted by parietal callus; callus and laterally directed sinus cause the sinus to appear spout-like. <i>Inner lip</i> recumbent, emarginated except on parietal wall; knob-like posteriorly forming parietal side of anal sinus, erect along anterior canal. <i>Anterior canal</i> is moderately long, turned slightly to the right when viewed ventrally; fasciole not swollen, with 6– 8 spiral threads; tip of canal very slightly notched. <i>Color</i> translucent white, ribs more opaque.</p> <p> <b> Remarks. <i>Taxonomy.</i></b> Leptadrillia loria closely matches the characteristics established by Woodring for the genus. Shells are spindle-shaped with a long anterior canal, ribs suture-to-suture, recurved on the shoulder, and shell surface smooth, except for spiral threads on the anterior canal. <i>Identification.</i> Bartsch roughly characterized <i>L. loria</i> as a small <i>L. splendida</i>. The holotype is 6.8 mm compared to the 9.2 mm length of the holotype of <i>L. splendida</i>. While they appear very similar in form, the anterior canal of <i>L. loria</i> is shorter in proportion to the rest of its shell than that of <i>L. splendida</i>, and the protoconch of <i>L. loria</i> is smaller. <i>Leptadrillia loria</i> is also similar to <i>Syntomodrillia socolatea</i>, new species, <i>S. triangulos</i>, new species and <i>S. mellea</i>, new species. From <i>S. socolatea</i> it differs in having a longer anterior canal, sigmoid ribs on the last whorl, not slightly opisthocline ribs, whorl peripheries closer to mid-whorl, a more streamlined body, and an all-white, not a light golden to chocolate brown color. From <i>S. triangulos</i> it differs in having a longer, more curved anterior canal, and a more streamlined shell, and lacking faint spirals between ribs on the last whorl. From <i>S. mellea</i> it differs in having a longer, more curved anterior canal, a slimmer shell, lacking faint spirals between ribs on the last whorl, and a different color—white, not light golden brown with whitish shell base and varix.</p>Published as part of <i>Fallon, Phillip J., 2016, Taxonomic review of tropical western Atlantic shallow water Drilliidae (Mollusca: Gastropoda: Conoidea) including descriptions of 100 new species, pp. 1-363 in Zootaxa 4090 (1)</i> on pages 223-224, DOI: 10.11646/zootaxa.4090.1.1, <a href="http://zenodo.org/record/263299">http://zenodo.org/record/263299</a>
Acquired C1-inhibitor deficiency in a patient with systemic lupus erythematosus: a case report and review of the literature
No full textExpression of class II major histocompatibility complex molecules in chronic pulmonary Mycoplasma bovis infection in cattle
No full textPulmonary inflammation often results in expression of the class II major histocompatibility complex (MHCII) by both professional antigen-presenting cells (APCs; histiocytes and lymphocytes) and non-professional APCs (respiratory epithelium and endothelium). In this study lesions from 17 cases of bovine chronic pneumonia, associated with Mycoplasma bovis infection, were examined immunohistochemically for M. bovis antigen and MHCII expression. Ten cases of chronic necrosuppurative bronchopneumonia (NBP) were shown to be characterized by abundant perinecrotic M. bovis antigen associated with scant MHCII expression by degenerate leucocytes. Seven cases of chronic catarrhal bronchointerstitial pneumonia (CBP) showed prominent MHCII expression by both professional APCs and respiratory epithelium, in the absence of intralesional M. bovis immunolabelling. The results suggest that prominent MHCII expression by both professional and non-professional APCs plays a role in the pathogenesis of M. bovis-induced CBP. Conversely, the role of MHCII expression in necrosuppurative foci typical of M. bovis-associated NBP can be considered negligible
Prevalenza degli herpesvirus nel tessuto epatico da soggetti con epatite C
No full textWe report the results of a study on the search for herpesvirus DNA in liver biopsy from patients with chronic hepatitis C and from a control group without hepatitis. Thirty-four liver samples from hepatitis C patients were examined, 12 of which (35.3%) were positive for at least one herpesvirus DNA, whereas among the 19 control liver samples only 2 were positive (10.5%; p= 0.049). Liver biopsies from 7 patients, 3 with acute hepatitis of unknown origin, 3 with non alcoholic steatoheapatitis and 1 with autoimmune hepatitis were investigated too and three positive samples were found. The prevalence of herpesvirus DNA higher in patients with hepatitis C than in individuals without hepatitis is discussed and the possible influence of herpesviruses both on the clinical course and on the therapy of hepatitis C is considered
