Architecture and gene repertoire of the flexible genome of the extreme acidophile Acidithiobacillus caldus.
PLoS ONE
PUBLISHED: 01-01-2013
Show Abstract
Hide Abstract
Acidithiobacillus caldus is a sulfur oxidizing extreme acidophile and the only known mesothermophile within the Acidithiobacillales. As such, it is one of the preferred microbes for mineral bioprocessing at moderately high temperatures. In this study, we explore the genomic diversity of A. caldus strains using a combination of bioinformatic and experimental techniques, thus contributing first insights into the elucidation of the species pangenome.

Effects of donepezil on behavioral manifestations of thalamic infarction: a single-case observation.
Front Neurol
PUBLISHED: 03-07-2011
Show Abstract
Hide Abstract
Objective: To examine the effect of donepezil for the treatment of cognitive and behavioral disorders associated with thalamic lesions in a 45-year-old male who suffered an infarct in the left thalamus. Background: Recent studies suggest that donepezil may improve executive functions impairments due to subcortical ischemic lesions. Method: The effects of donepezil were analyzed in a single-case of thalamic infarction with cognitive and behavioral alterations in an open label study. Results: Significant behavioral modifications related to improved performances in executive functions were observed with the treatment. Conclusion: The results suggest that donepezil may have significant effect on executive functions that can alter behavioral outcomes after thalamic infarctions.

Pan-urothelial verrucous carcinoma unrelated to schistosomiasis.
BMJ Case Rep
PUBLISHED: 04-17-2009
Show Abstract
Hide Abstract
Verrucous carcinoma is a well differentiated squamous cell carcinoma with a well known histological appearance and clinical behaviour. We present a case of verrucous carcinoma extensively affecting the urothelium of the right renal pelvis, right ureter and urinary bladder over a 3-year period. This pan-urothelial involvement of a verrucous carcinoma has not been previously reported. The potential for regional spread with subsequent urinary tract obstruction by this tumour calls for aggressive local surgical treatment as the main modality of therapy.

Mucinous cystadenocarcinoma of the renal pelvis: a case report and clues to histogenesis.
BMJ Case Rep
PUBLISHED: 02-02-2009
Show Abstract
Hide Abstract
We present a case of mucinous cystadenocarcinoma of the renal pelvis associated with a collecting duct carcinoma in a 58-year-old woman with diabetes. Even though several theories about the aetiology of mucinous cystadenocarcinoma of the renal pelvis have been proposed, its origin remains unknown. The present case shows a distinct morphology and immunohistochemical profile that may suggest a clue to its histogenesis.

Thiol/Disulfide system plays a crucial role in redox protection in the acidophilic iron-oxidizing bacterium Leptospirillum ferriphilum.
PLoS ONE
Show Abstract
Hide Abstract
Thiol/disulfide systems are involved in the maintenance of the redox status of proteins and other molecules that contain thiol/disulfide groups. Leptospirillum ferriphilum DSM14647, an acidophilic bacterium that uses Fe(2+) as electron donor, and withstands very high concentrations of iron and other redox active metals, is a good model to study how acidophiles preserve the thiol/disulfide balance. We studied the composition of thiol/disulfide systems and their role in the oxidative stress response in this extremophile bacterium. Bioinformatic analysis using genomic data and enzymatic assays using protein extracts from cells grown under oxidative stress revealed that the major thiol/disulfide system from L. ferriphilum are a cytoplasmic thioredoxin system (composed by thioredoxins Trx and thioredoxin reductase TR), periplasmic thiol oxidation system (DsbA/DsbB) and a c-type cytochrome maturation system (DsbD/DsbE). Upon exposure of L. ferriphilum to reactive oxygen species (ROS)-generating compounds, transcriptional activation of the genes encoding Trxs and the TR enzyme, which results in an increase of the corresponding activity, was observed. Altogether these data suggest that the thioredoxin-based thiol/disulfide system plays an important role in redox protection of L. ferriphilum favoring the survival of this microorganism under extreme environmental oxidative conditions.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
