The use of the tunicate Ciona intestinalis as a model system to study the relationship between regeneration and aging is reviewed. Ciona has powerful regeneration capacities, which fade with age. Some additional benefits are-, a relatively short life span, the ability to study regeneration in vitro, the close phylogenetic relationship between tunicates and vertebrates, and the host of molecular...

One of the main goals in genome sequencing projects is to determine a haploid consensus sequence even when clone libraries are constructed from homologous chromosomes. However, it has been noticed that haplotypes can be inferred from genome assemblies by investigating phase conservation in sequenced reads. In this study, we seek to infer haplotypes, a diploid consensus sequence, from the genome...

The current study aims to determine the involvement of cellular responses in combating Giardia intestinalis invasion. The study group consisted of 44 women and 18 men, aged 18-72 years, infected with G. intestinalis. The diagnosis was established based on laboratory investigations (examination of stool, choloscopy, GSA-65). Blood for analysis was collected before antiparasitic treatment and two...

Non-indigenous species (NIS) can pose a significant level of risk, through potential ecological or genetic consequences, to environments to which they are introduced. One way to characterize the overall risk posed by a NIS is to combine the probability and consequences of its establishment in a risk assessment that can be used to inform managers and policy-makers. The vase tunicate Ciona intest...

Variations in protein, lipid, carbohydrate and astaxanthin content of Enteromorpha intestinalis, Ulva lactuca and Catenella repens were documented over a 10 months period from September 2007 to June 2008. The macroalgal species were collected from six sampling stations of Indian Sundarbans, a Gangetic delta at the apex of Bay of Bengal. On dry weight basis, the protein content varied from 4.15±...

Suppressive subtractive hybridization was conducted to identify unique genes coding for plant cell wall hydrolytic enzymes and other properties of the gastrointestinal bacterium Fibrobacter intestinalis DR7 not shared by Fibrobacter succinogenes S85. Subtractive clones from F. intestinalis were sequenced and assembled to form 712 nonredundant contigs with an average length of 525 bp. Of these, ...

A 92yearold woman was transferred to our hospital because of diarrhea and vomiting. Approximately 1 month earlier, the patient was admitted to another hospital for the treatment of aspiration pneumonia and pyelonephritis. She had been well with hydration and antibiotics including piperacillintazobactam until 2 days before this presentation, when diarrhea and vomiting developed. On examination, ...

We report the main characteristics of "Collinsella bouchesdurhonensis" strain Marseille-P3296, which was isolated from a stool sample of a healthy 50-year-old pygmy (Baka) woman.
