Projections of the future occurrence, distribution, and seasonality of three species in the Chesapeake Bay under a high-emission climate change scenario.

Illness caused by pathogenic strains of bacteria incurs significant economic and health care costs in many areas around the world. In the Chesapeake Bay, the two most problematic species are . and .

Benefits of mineralized bone cortical allograft for immediate implant placement in extraction sites: an study in dogs.

Purpose: The aim of the present study was to evaluate the effectiveness of using a mineralized bone cortical allograft (MBCA), with or without a resorbable collagenous membrane derived from bovine pericardium, on alveolar bone remodeling after immediate implant placement in a dog model.

Methods: Six mongrel dogs were included. The test and control sites were randomly selected.

[Molecular characterization of extended-spectrum ss-lactamases-producing Escherichia coli and Klebsiella pneumoniae in hospitals of the Caribean Region, Colombia].

ESBL-producing in Enterobacteriaceae, is the main resistance mechanism to extended spectrum cephalosporin and monobactams. Seventy isolates collected of hospitals in four cities of the Colombian Caribean, were characterized to ESBL production and metalo-beta-lactamases by microbiological test. The ss-lactamases characterization were performed by IEF and RPC; genotyping by PFGE.

[Comparative light microscopy study of periapical and pulpal response to different stimuli (2)].

In this communication, the second of three we report the periapical and pulpal response against electric stimulation and pulpal exposure, after 20 weeks. We analyzed the quantitative cellular findings encountered in the periapical areas are presented.

[Comparative light microscopy study of periapical and pulpal response to different stimuli (1)].

A comparative study of pulpal and periapical responses to pulpal exposure and electric stimulus. In this report we communicate the changes found in the pulp and supporting tissues.
