The occlusive tourniquet: a simple method for rectal stump washout during open and laparoscopic surgery.
2007
Rectal stump washout with cytolytic agents is recommended and usually performed during anterior rectal or rectosigmoid resection. The use of a linear stapler instrument during ultralow anterior resection makes the placement of pelvic clamps difficult for rectal stump washout prior to resection. The objective of this work is to demonstrate the use of a simple procedure, the occlusive tourniquet for rectal stump washout. Occlusive tourniquet applied to open technique: after complete dissection of the rectum and sigmoid colon according to the usual technique, a simple piece of tubing from an intravenous line is passed behind and around the rectum/sigmoid colon at some point distal to the tumor…

Variant Arterial Supply of the Descending Colon by the Coeliac Trunk: A Case Report
2021
Background and Objectives: Knowledge of arterial variations of the intestines is of great importance in visceral surgery and interventional radiology. Materials and Methods: An unusual variation in the blood supply of the descending colon was observed in a Caucasian female body donor. Results: In this case, the left colic artery that regularly derives from the inferior mesenteric artery supplying the descending colon was instead a branch of the common hepatic artery. Conclusions: Here, we describe the very rare case of an aberrant left colic artery arising from the common hepatic artery in a dissection study.
La conquista è un sostantivo femminile. Donne e avventura coloniale dell'Italia liberale del Corno d'Africa
2016
Tra gli aspetti maggiormente e volutamente rimossi della nostra avventura coloniale, c’è quello che riguarda il coinvolgimento e il ruolo delle donne nell’avventura coloniale nonché l’atteggiamento adottato dagli Italiani (di entrambi i sessi) nei confronti delle donne colonizzate. Se le donne italiane dapprima escluse furono, in un secondo momento, invitate ad esportare oltremare i valori della famiglia, propaganda di Stato, fotografia, canzoni, pubblicità, realizzazioni filmiche, letteratura e pretesi discorsi scientifici hanno veicolato, dal canto loro, dapprima una retorica di genere che ha mercificato la donna indigena come preda sessuale, e, in un secondo momento, l’ha demonizzata rov…
Prefazione
2016
Le contaminazioni e le compresenze culturali, in ragione di esperienze ‘de-localizzanti’, trovano nella scrittura un fecondo luogo di espressione delle istanze più variegate e distanti del complesso problema della ‘convivenza’. Un tema che è d’obbligo oggi indagare non più nella ricerca di un luogo di confronto tra due elementi contrapposti che darebbero origine alla semplice somma di due parti, ma nella prospettiva di trovare una dimensione ‘terza’, intersoggettiva, in cui si ingenera la necessità – non sempre soddisfatta – della rinuncia alla esclusiva proiezione del sé. L’esperienza del superamento del ‘limite’, geografico e/o identitario, trova in sede letteraria il naturale luogo di el…
Al di qua e al di là della colonia: satira come opposizione al regime coloniale in un racconto di 'Ali Mustafà al-Misrati
2012
Italian scholars and Arabists have only recently started to pay attention towards Libya and this country's rich and fascinating literary production. Libyan writers are, in fact, still unknown to most people in Italy, where merely a few Italian translations of Libyan works and critical essays on Libyan literature have been published until now. Yet, Libya's contemporary literary scene features outstanding figures, such as the eclectic writer 'Ali Mustafà al-Misrati, whose novels, short stories and essays deal with significant historical, political and social themes. Starting from the analysis of one of author's tales focused on the Libyan opposition against Italian colonialism, this article p…
The prologue and the fi rst stasimon of Oedipus at Colonus: a comparative study
2017
En este trabajo proponemos un análisis del estásimo primero de la tragedia Edipo en Colono de Sófocles a partir de los versos 16 a 18 del prólogo de la misma obra. La comparación entre ambos pasajes puede ser importante en la medida en que el ἄλσος descrito en el prólogo es presentado como un espacio, dramáticamente importante, que se desarrolla poéticamente en el primer estásimo. Ambas descripciones presentan puntos en común que no sólo pueden ayudarnos a entender mejor la naturaleza de este bosque sagrado, sino también evidencian la programación dramática de los susodichos versos prologales. In this paper we analyze the fi rst stasimon of the tragedy Oedipus at Colonus of Sophocles based …
TLR2, TLR4 and Dectin-1 signalling in hematopoietic stem and progenitor cells determines the antifungal phenotype of the macrophages they produce
2016
TLRs represent an attractive target for the stimulation of myeloid cell production by HSPCs. We have previously demonstrated that HSPCs use TLR2 to sense Candida albicans in vivo and induce the production of macrophages. In this work, we used an in vitro model of HSPCs differentiation to investigate the functional consequences for macrophages of exposure of HSPCs to various PAMPs and C. albicans cells. Mouse HSPCs (Lin(-) cells) were cultured with M-CSF to induce macrophage differentiation, in the presence or absence of the following PRR agonists: Pam3CSK4 (TLR2 ligand), LPS (TLR4 ligand), depleted zymosan (which only activates Dectin-1), or C. albicans yeasts (which activate several PRRs, …
In Vitro Expression of the Endothelial Phenotype: Comparative Study of Primary Isolated Cells and Cell Lines, Including the Novel Cell Line HPMEC-ST1…
2002
Endothelial cell lines are commonly used in in vitro studies to avoid problems associated with the use of primary endothelial cells such as the presence of contaminating cells, the difficulty in obtaining larger numbers of cells, as well as the progressive loss of cell viability and expression of endothelial markers in the course of in vitro propagation. We have analyzed the characteristics defining distinctive endothelial phenotypes in the cell lines EA.hy926, ECV304, EVLC2, HAEND, HMEC-1, ISO-HAS-1 and a cell line recently generated in our laboratory, HPMEC-ST1.6R, and have compared these phenotypes with those found in primary human endothelial cells isolated from umbilical vein (HUVEC), …
Modulation of Forssman Glycosphingolipid Expression by Murine Macrophages: Coinduction with Class II MHC Antigen by the Lymphokines IL4 and IL6
1990
In contrast to murine spleen M phi, resident peritoneal M phi from health mice express very little Forssman glycolipid antigen (Fo). The following experiments suggest that Fo expression by peritoneal M phi may be associated with inflammation. Balb/c and CBA/J mice were given inflammatory stimuli by i.p. injection of live BCG, thioglycollate (TG), Corynebacterium parvum (CP), proteose peptone (PP), or LPS. Control animals received pyrogen-free saline. Expression of Fo and Ia antigen by peritoneal M phi was determined by immunofluorescence after 4 d. Application of TG or CP led to an up to 30-fold increase in Fo+, Ia+ double positive M phi over that in control animals. LPS caused mainly an in…
