We propose that many of the ecological surprises that have confronted society over the past centuries—pandemics, population collapses of species we value and eruptions of those we do not, major shifts in ecosystem states, and losses of diverse ecosystem services—were caused or facilitated by altered top-down forcing regimes associated with the loss of native apex consumers or the introduction of exotics. Our repeated failure to predict and moderate these events result not only from the complexity of nature but from fundamental misunderstandings of their root causes.

With the recent discovery of lymph vessels in the human brain , never mind the glymphatic and perivascular drainage systems, does anybody truly understand how waste proteins leave the aging brain? And what do pericytes do, exactly? On Monday, October 30, leading international experts on protein clearance in neurodegenerative disease will discuss these questions and more during a daylong conference organized by UCL’s Leonard Wolfson Experimental Neurology Centre in London (see program ). The meeting is sold out, but anyone can watch it on the UCLTV You Tube Channel , while joining a twitter debate via #UCLDementiaSeminars . 

In humans, a gut flora similar to an adult's is formed within one to two years of birth. [4] As the gut flora gets established, the lining of the intestines – the intestinal epithelium and the intestinal mucosal barrier that it secretes – develop as well, in a way that is tolerant to, and even supportive of, commensurate microorganisms to a certain extent and also provides a barrier to pathogenic ones. [4] Specifically, goblet cells that produce the mucosa proliferate, and the mucosa layer thickens, providing an outside mucosal layer in which "friendly" microorganisms can anchor and feed, and an inner layer that even these organisms cannot penetrate. [4] [5] Additionally, the development of gut-associated lymphoid tissue (GALT), which forms part of the intestinal epithelium and which detects and reacts to pathogens, appears and develops during the time that the gut flora develops and established. [4] The GALT that develops is tolerant to gut flora species, but not to other microorganisms. [4] GALT also normally becomes tolerant to food to which the infant is exposed, as well as digestive products of food, and gut flora's metabolites produced from food. [4]

Gastric adenocarcinoma, intestinal type . Tumor cells describe irregular tubular structures, with stratification, multiple lumens surrounded by a reduced stroma ("back to back" aspect). The tumor invades the gastric wall, infiltrating the muscularis mucosae, the submucosa and thence the muscularis propria. Often it associates intestinal metaplasia in adjacent mucosa. Depending on glandular architecture, cellular pleomorphism and mucosecretion, adenocarcinoma may present 3 degrees of differentiation : well (photo), moderate and poorly differentiate. (H&E, ob. x10)
