Tracking Down Duodenopancreatic Malignancy

Tracking Down Duodenopancreatic Malignancy

BACKGROUND Malignant tumours of the duodenum are rare and often difficult to diagnose. Due to the small clinical experience with duodenal malignancies their prognosis is unknown and resection is the treatment of choice. CASE REPORT Adding to a small series of incidental tumours, we report the case of a 65-year-old patient with primary extranodal (MALT-) lymphoma of the duodenum infiltrating t...

Tracking down noncoding RNAs.

U ntil relatively recently, RNA has taken a predominantly backstage role compared to protein in genome studies. However, this is changing dramatically with the discovery of a plethora of RNAs that do not act as messenger (mRNA), transfer (tRNA), or ribosomal (rRNA) RNAs (1–3). These noncoding RNAs (ncRNAs) play a role in a variety of processes such as transcriptional regulation, chromosome repl...

Tracking algorithms chase down pathogens.

Understanding subcellular dynamic processes governing pathogenic mechanisms is a necessary step towards the development of new drugs and strategies against infectious diseases. Subcellular pathogenic mechanisms, such as viral invasion processes involve highly dynamic nanometric-scale objects and rapid molecular interactions that require the study of individual particle paths. Single-particle tr...

Tracking down worldwide Puccinia psidii dispersal

Background Puccinia psidii causes rust disease on many host species in the Myrtaceae [1]. First reported in 1884 on guava in Southern Brazil [2], the rust has since been detected on several myrtaceous in South America, Central America, Caribbean, Mexico, USA: in Florida, California, and Hawaii. More recently, P. psidii was reported in Japan infecting M. polymorpha[3]. Of special note is that a ...
