The green macroalgae, Enteromorpha compressa (Linnaeus) Nees, Ulva lactuca, and E. linza, were seasonally collected from Abu Qir bay at Alexandria (Mediterranean Sea) This work aimed to investigate the seasonal environmental conditions, controlling the green algal growth, predominance, or disappearance and determining antioxidant activity. The freshly collected selected alga (E. compressa) was ...

The multicellular green alga Enteromorpha (Ulvales, Chlorophyta) includes some economically valuable species cultivated as "Aonori" (green laver) in Japan. The life cycle of the genus Enteromorpha consists of gametophytic and sporophytic foliaceous thalli, which are indistinguishable in appearance. Both male and female gametes of E. compressa can grow parthenogenetically and can be cloned into ...

Pneumatosis intestinalis is an uncommon disorder characterized by an accumulation of gas in the bowel wall. We described three cases undertaking liver transplantation. The patients developed diarrhea in three cases and high fever in two. An abdominal X-ray and computed tomography scan demonstrated extensive pneumatosis intestinalis in the colon with pneumoperitoneum mimicking hollow organ perfo...

A new species of microsporidian, Septata intestinalis, was recently recognized as an opportunistic pathogen of AIDS patients. In this study, it was cultured from the nasopharyngeal aspirate of a human immunodeficiency virus type 1-infected patient with disseminated microsporidiosis. In human embryonic lung cells exposed to S. intestinalis, a cytopathic effect appeared within 28 days as foci of ...

Pneumatosis intestinalis (PI), defined as gas within the bowel wall, is an uncommon radiographic sign which can represent a wide spectrum of diseases and a variety of underlying diagnoses. Because its etiology can vary greatly, management of PI ranges from surgical intervention to outpatient observation (see, Greenstein et al. (2007), Morris et al. (2008), and Peter et al. (2003)). Since PI is ...

The innate immunity of ascidian hemocytes is considered to be a prototype of that in vertebrates. In this study, we identified as many transcripts as possible that were expressed specifically in hemocytes of Ciona intestinalis, a ubiquitous species of ascidian. Using a large-scale whole-mount in situ hybridization (WISH) technique and young adult specimens of C. intestinalis, 34 such transcript...

Concentrations of Al, B, Ba, Cd, Cr, Ni, Pb and Sr were analyzed by inductively coupled plasma optical emission spectroscopy (ICP-OES) in the Ligula intestinalis plerocercoid (L., 1758), its host tissues (Tinca tinca L., 1758), sediment and water from Beyşehir Lake. Al, Ba, Cd, Cr, Ni, Pb and Sr were highest in sediment, while B was the highest in liver. Al in Ligula intestinalis plerocercoid w...

69 Sir, An 81‐year‐old man who had habitual constipation visited our hospital complaining of vomiting. His abdomen showed distension without tenderness. Abdominal X‐ray showed dilatation of stomach, with gas in the small and large intestines [Figure 1]. Computed tomography revealed numerous gas cysts in the wall of stomach, small and large intestines [Figure 2, arrows], and portal venous system...

With the purpose of verify the presence of larvae from the genus Gasterophilus in the Rio Grande do Sul State, a study was undertaken using 395 horses taken to slaughter in the city of Pelotas. The material analysis revealed that 126 animals (31,90%) presented infection, with 100 animals (25,32%) infected by Gasterophilus nasalis, and 47 animals (11,90%) infected by G. intestinalis. These resul...

Pneumatosis cystoides intestinalis is a rare disorder with multiple submucosal or subserosal gas-filled cysts along the gastrointestinal wall. Pneumatosis intestinalis can be classified as either primary (idiopathic) or secondary. In the latter form, a causal relationship has been established with chronic obstructive pulmonary disease, amyloidosis, infectious colitis, intestinal obstruction, is...
