Stratification of Fusobacterium nucleatum by local health status in the oral cavity defines its subspecies disease association.

The ubiquitous inflammophilic oral pathobiont Fusobacterium nucleatum (Fn) is widely recognized for its strong association with inflammatory dysbiotic diseases and cancer. Fn is subdivided into four subspecies, which are historically considered functionally interchangeable in the oral cavity. To test this assumption, we analyzed patient-matched dental plaque and odontogenic abscess clinical specimens and examined whether an inflammatory environment selects for/against particular Fn subspecies.

The prevalence of subspecies in the oral cavity stratifies by local health status.

The ubiquitous inflammophilic pathobiont is widely recognized for its strong association with a variety of human dysbiotic diseases such as periodontitis and oral/extraoral abscesses, as well as multiple types of cancer is currently subdivided into four subspecies: subspecies () ( (), and (). Although these subspecies have been historically considered as functionally interchangeable in the oral cavity, direct clinical evidence is largely lacking for this assertion. Consequently, we assembled a collection of oral clinical specimens to determine whether subspecies prevalence in the oral cavity stratifies by local oral health status.

Morphological studies on the prehatching development of the glandular stomach of Japanese quails using light, electron, and fluorescent microscopy.

The development of the glandular stomach was studied using light, electron, and fluorescent microscopy. The research used 130 Japanese quail eggs from the second to the seventeenth days of incubation.The proventriculus could be distinguished on the3rd day.

Evolution of liver fibrosis after interferon-based anti-hepatitis C virus therapy failure in 3,049 chronic hepatitis C patients without cirrhosis.

Background And Study Aims: Liver fibrosis is the underlying causeof hepatitis C virus (HCV)-related disease progression to endpoints such as cirrhosis, liver failure, and hepatocellular carcinoma. The aim of our study was to assess changes in hepatic fibrosis in patients with chronic HCV who had a fibrosis evaluation at two time points at least six months apart.

Patients And Methods: This was a retrospective cohort study that included patients who had failed interferon therapy and received HCV retreatment with direct-acting antivirals (DAAs) at least six months later.

Effect of three insect growth regulators on certain biological aspects of the lesser grain borer, Rhyzopertha dominica (Coleoptera: Bostrichidae).

The current study was performed to evaluate the efficacy of certain insect growth regulators (IGRs), buprofezin, hexaflumuron, and lufenuron, at different concentrations (0.2, 0.4, and 0.
