Aproximación a la lengua de los tratados hipocráticos De fistulis y De haemorrhoidibus

2003

A partir de una aproximación previa en un trabajo anterior a propósito de aspectos fonéticos y morfológicos en dos tratados quirúrgicos del Corpus Hippocraticum, De fistulis y De haemorrhoidibus, en el presente artículo se quiere continuar esta labor en el terreno de la sintaxis y el vocabulario, con vistas a poner de relieve algunos rasgos de griego helenístico que, claramente, aparecen en estos tratados. Todo ello refuerza la opinión de que estos tratados son obras de pleno siglo IV a. C., De haemorrhoidibus probablemente de mediados de siglo y De fistulis quizá algo anterior. From a previous approach about phonetic and morphological features in the Hippocratic treatrises De fistulis and …

Evaluation of different transvaginal sonographic diagnostic parameters in women with postmenopausal bleeding

1998

Objective To determine whether the accuracy of transvaginal sonography to detect endometrial pathology is enhanced by assessing endometrial morphology and the regularity of the endometrial border in addition to measurement of endometrial thickness in women with postmenopausal bleeding. Design and methods A total of 159 women with post-menopausal bleeding were included in a prospective study performed at the Clinic of Obstetrics and Gynecology, University of Mainz. The results obtained on transvaginal sonographic assessment of the endometrium were compared with the histological evaluation of the operative endometrial specimen. Results A cut-off level for endometrial thickness of 5 mm had a s…

Flowers and inflorescences of the seagrassPosidonia(Posidoniaceae, Alismatales)

2012

Premise of the study: The predominantly aquatic order Alismatales displays a highly variable fl ower groundplan associated with a diverse range of developmental patterns. We present the fi rst detailed description of fl ower anatomy and development in Posidonia , the sole genus of the seagrass family Posidoniaceae. Existing accounts provide confl icting interpretations of fl oral and infl orescence structure, so this investigation is important in clarifying morphological evolution within this early-divergent monocot order. • Methods: We investigated two species of Posidonia using light microscopy and scanning electron microscopy. Our observations are interpreted in the framework of a recent…

New knowledge on the Monte Conca gypsum karst system (Central-western Sicily, Italy)

2011

The Monte Conca karst system is located in Central-Western Sicily, where Messinian evaporites are widespread. Here, the evaporites lie on lower Messinian-middle Serravallian clayey-marly-sandy deposits and are overlain locally by Pliocene marly limestones. These successions are affected by E-W, and to a lesser degree N-S and NW-SE, high-angle faults that have also produced lateral contacts between the gypsum units and the clayey-marly deposits. The cave passages reachaltogether about 2.4 km in lengthand 130 m in depth, and the system consists of a sink cave, a resurgence and a relict resurgence. At large scale it is characterized by superimposed levels of sub-horizontal galleries connected …

Forma esteriore e vita interiore: Ernst Haeckel e la morfologia del vivente

2016

Ernst Haeckel, scienziato per professione e artista per passione, mise l’arte a disposizione delle ricerche morfologiche, proponendo una scienza unitaria del vivente, in grado di comprendere l’organismo nella sua totalità funzionale ed estetica. Nei tre saggi qui raccolti egli indaga la forma esteriore dei viventi, cogliendo in essa l’indicazione di una vita interiore, una vis plastica che anima la natura in ogni sua manifestazione, dà impulso alla differenziazione funzionale e sancisce la continuità fra organico e inorganico. Espressioni come “vita dei cristalli” e “anima cellulare” appaiono qui prive di contraddizione e la natura, creatrice inconscia di forme, diviene essa stessa un’opera…

Root Canal Morphology and Configuration of the Mandibular Canine: A Systematic Review

2021

The aim of this study was to systematically review the root canal morphology and configuration (RCC) of mandibular canines (MaCa). The review was registered in the PROSPERO database (ID-272297) and it was carried out following the PRISMA guidelines. Three electronic databases (MEDLINE via PubMed, Embase, Scopus) were searched. Randomized controlled trials, cross-sectional, cohort, comparative, evaluation and validation studies have been included. The anatomical quality assessment (AQUA) tool was used for a quality assessment of the anatomical studies. Of 910 studies retrieved from the systematic search, 28 studies investigating RCCs were included. Most MaCa were single-rooted (87.9–100%), w…

Comparative study of the arterial and lacunary systems of the ventricular myocardium of elasmobranch and teleost fishes.

1983

The typical fish heart has a spongy trabeculated ventricular myocardium (spongiosa) supplied by the venous blood of the intertrabecular spaces (lacunae); hence it is called a "venous heart." However, in some fishes a more complex ventricular muscle is found (mixed type), in which the spongiosa is covered by an outer layer of densely arranged myocardial bundles (compacta). The compacta receives oxygenated blood from the coronary vessels. The objective of this study was to investigate relations between myoarchitecture and blood supply with an emphasis on the hitherto unexplored, putative vascular connections between the arterial and the lacunary circuits. Using histological methods combined w…

The mesothoracic wings of Afrotropical Scutelleridae (Hemiptera: Heteroptera): morphology and taxonomic significance

2013

Mesothoracic wings have been examined and compared in 32 species representing 20 genera of Afrotropical Scutelleri- dae. Morphological characters of the corium are described. Three main types of mesothoracic wing venation patterns can be recognized. The taxonomic significance of forewi ng characters in Scutelleridae is briefly discussed.
