Characterization of a hyaluronic acid-based hydrogel containing an extracellular oxygen carrier (M101) for periodontitis treatment: An in vitro study.

Periodontitis is an inflammatory disease associated with anaerobic bacteria leading to the destruction of tooth-supporting tissues. Porphyromonas gingivalis is a keystone anaerobic pathogen involved in the development of severe lesions. Periodontal treatment aims to suppress subgingival biofilms and to restore tissue homeostasis.

Thermococcus piezophilus sp. nov., a novel hyperthermophilic and piezophilic archaeon with a broad pressure range for growth, isolated from a deepest hydrothermal vent at the Mid-Cayman Rise.

A novel strictly anaerobic, hyperthermophilic archaeon, designated strain CDGS, was isolated from a deep-sea hydrothermal vent in the Cayman Trough at 4964m water depth. The novel isolate is obligate anaerobe and grows chemoorganoheterotrophically with stimulation of growth by sulphur containing compounds. Its growth is optimal at 75°C, pH 6.

Hepatocellular carcinoma in HIV hepatitis C virus.

Purpose Of Review: Recent data showed that in some settings with adequate resources liver diseases rank first among the causes of death in persons living with HIV (PLHIV). Although liver decompensation is the first cause of hepatic death in PLHIV, hepatocellular carcinoma (HCC) is also emerging as one of the causes of hepatic death in PLHIV. This review analyzes the main data published on HCC in PLHIV in the last 3 years.

Percutaneous and surgical treatment of pyogenic liver abscesses: observation over a 21-year period in 148 patients.

Background: Percutaneous drainage of pyogenic liver abscess has become first-line treatment. In the past surgical drainage was preferred in some centres.

Aim: The aim of this retrospective study was to assess the effectiveness of percutaneous treatments and surgical drainage, in terms of treatment success, hospital stay and costs.
