ARGONAUTE10 controls cell fate specification and formative cell divisions in the Arabidopsis root.

A key question in plant biology is how oriented cell divisions are integrated with patterning mechanisms to generate organs with adequate cell type allocation. In the root vasculature, a gradient of miRNA165/6 controls the abundance of HD-ZIP III transcription factors, which in turn control cell fate and spatially restrict vascular cell proliferation to specific cells. Here, we show that vascular development requires the presence of ARGONAUTE10, which is thought to sequester miRNA165/6 and protect HD-ZIP III transcripts from degradation.

Insights into the role of alternative splicing in plant temperature response.

Alternative splicing occurs in all eukaryotic organisms. Since the first description of multiexon genes and the splicing machinery, the field has expanded rapidly, especially in animals and yeast. However, our knowledge about splicing in plants is still quite fragmented.

Pneumatosis cystoides intestinalis induced by the alpha-glucosidase inhibitor complicated from sigmoid volvulus in a diabetic patient.

Introduction: We present the case of a diabetic patient on treatment with acarbose who had presented a sigmoid volvulus with localized cystic pneumatosis of the sigmoid colon.

Case Report: A 72-year-old patient with a medical history of atrial fibrillation, DNID in treatment since 10 years by acarbose. The patient was admitted to the emergency for abdominal pain and occlusive syndrome since 48 h without fever or nausea or vomiting.

The Rapunzel syndrome: case report and review of the literature.

We report a case of a gastric trichobezoar (TB) extending throughout the small bowel in a child. The possibility of a TB causing an epigastric mass should be borne in mind, and ultrasonography could be used to support such a diagnosis. These bezoars should be considered to possibly have extensions for which there may be no preoperative or endoscopic evidence.

[A rare case of proctorrhagia. Apropos of a case and review of the literature].

The authors report a case of a tumour arising in an aberrant intrasplenic pancreas, forming a fistula with the left colon, responsible for rectal bleeding in a 75 year old woman and treated by surgical resection. This tumour is classified as a heterotopic pancreatic tumour. As in the other two cases described in the literature, this tumour was found to be an intrasplenic mucinous cystadenocarcinoma which has a more favourable prognosis than heterotopic adenocarcinomas (29 cases reported).
