Puzzle In The Control Of Cell Division Unraveled




A puzzle in the control of cell division, one of the most fundamental processes in all biology, has been unraveled. Although the steps of cell division are familiar to all pupils studying biology in schools, the details of how cell division is controlled and errors avoided have still to be sorted out.

Minimally Invasive Surgical Enucleation or Esophagogastrectomy for Benign Tumor of the Esophagus

Experience in surgical resection of benign tumor of the esophagus is limited. Authors performed a chart review of 5 patients who underwent minimally invasive surgical resection of benign esophageal tumor. Main outcome measures included operative approaches, tumor's location and size, and outcomes. Tumor location were middle esophagus (n = 1), distal esophagus (n = 2), and gastroesophageal junction (n = 2). There were 4 females with a mean age of 55 years. Surgical approaches included thoracoscopic enucleation (n = 1), laparoscopic enucleation (n = 1), and laparoscopic and thoracoscopic Ivor Lewis esophagogastrectomy (n = 3). There were no open conversions. Mean operative time for enucleation was 127 minutes and 240 minutes for Ivor Lewis esophagectomy. Mean hospital stay was 5.8 days. There were no major or minor complications. Three patients developed stomal stenosis. The 30-day mortality was zero. Surgical pathology showed leiomyoma in 3 patients and gastrointestinal stromal tumor in 2 patients. Tumor size ranged from 1.1 to 10.5 cm. There has been no tumor recurrence at a mean follow-up of 14 months. Minimally invasive surgical enucleation or esophagogastrectomy for benign esophageal tumor is feasible and safe. The optimal approaches should be tailored based on the location and size of the tumor.

The Dental Mercury Controversy    

While there is no disputing the toxicity of mercury to human tissue and its cumulative degenerative effects on neural and brain tissue, there exists no universally accepted scientific data to date to substantiate the claim that mecury in dental fillings have an adverse effect on your health. The main reason today for removal of old amalgam filings is to remove recurrent decay and improve dental aesthetics. Dr. Wright stopped using dental amalgam in his practice fifteen years ago and .....

New light microscope sharpens scientists' focus
A new light microscope so powerful that it allows scientists peering inside cells to discern the precise location of nearly each individual protein they are studying has been developed and successfully demonstrated by scientists at the Howard Hughes Medical Institute's Janelia Farm Research Campus in collaboration with researchers at the National Institutes of Health and Florida State University.
