Effectiveness of proliferating tissues in combination with bovine-derived xenografts to intrabony defects of alveolar bone in dogs

Neighborly relations and self-neglect in older adults living alone: a cross-sectional study in rural areas of Southwest China

OBJECTIVES

This study aims to examine the association between neighborly relations and self-neglect.

METHODS

We used the Scale of the Elderly Self-neglect to measure elder self-neglect. Logistic regression was used to examine the association between neighborly relations and self-neglect and its' phenotypes.

RESULTS

After adjusting for potential confounders, the risk of overall self-neglect among individuals with harmonious neighbor relationships significantly decreased by 79.2%. In comparison to elderly individuals living alone with poor neighbor relationships, those with harmonious connections experienced a 77.6% reduction in the risk of medical self-neglect, an 89.9% decrease in the risk of hygiene self-neglect, a 65.1% decline in the risk of emotional self-neglect, a 77.9% drop in the risk of safety self-neglect, and a 56.8% lower risk of social self-neglect.

CONCLUSION

This study highlights harmonious neighborly relations are an independent protector factor for self-neglect. Fostering neighborly relations might be a practical approach to mitigating self-neglect.

Preparation and Histological Study of Multi-Walled Carbon Nanotubes Bone Graft in Management of Class II Furcation Defects in Dogs

BACKGROUND:

The main target of periodontal disease and alveolar bone defeat treatment is the regeneration of the lost structures.

AIM:

This work deals with the evaluation of the effect of functionalised multi-walled carbon nanotubes (MWCNTs), as grafting material in the management of furcation defects created in dogs.

MATERIAL AND METHODS:

Potential cytotoxicity of the grafting material was assessed. Scanning electron microscope (SEM) and energy dispersive x-ray (EDX) analysis after incubation of the grafting material in simulated body fluid (SBF) at pH 7.4 and 37°C for one week was done. In six healthy mongrel dogs’ full-thickness mucoperiosteal flaps were raised on the buccal aspects to create two walls intrabony defects at the furcation areas. The mandibular premolar area received the grafting material. Histological evaluation was carried out at 1, 2- and 3-months’ period.

RESULTS:

Cytotoxicity results proved the safety of grafting material application. The prepared material exhibited good Ca-apatite crystal patterns at the surface revealed by SEM and high calcium content showed by EDX results. Good bone formation ability was also apparent histologically.

CONCLUSION:

The prepared grafting material (MWCNTs) can serve as a delivery vehicle for osteogenic cells and osteogenic growth factor proteins in the bone development process.
