Chronic hyperglycaemia is a chief feature of diabetes mellitus and complicates with many systematic anomalies. Non-human primates (NHPs) are excellent for studying hyperglycaemia or diabetes and associated comorbidities, but lack behavioural observation. In the study, behavioural, brain imaging and histological analysis were performed in a case of spontaneously hyperglycaemic (HGM) Macaca fascicularis.

Given the high degree of shared processing in neural structures, it is critical to understand if neurostimulation affects functions that are related to, but not targeted by, the intervention. Here, we approach this question by studying the effects of electrical stimulation of cutaneous afferents on unrelated processing of proprioceptive inputs.

A large variety of graft materials have been used for maxillary and mandibular atrophy. To date there has been no graft material, which can be regarded as completely satisfactory.

Angiogenesis is associated with a series of inductive, permissive and restrictive communications that result in the appearance, differentiation, and formation of new vessels. The goal of therapeutic angiogenesis is to improve blood circulation, relay survival factors and regenerative stem cell populations to sites of tissue repair, and ultimately recover function and form of the tissue.

Autologous lipofilling has several advantages, including biocompatibility, versatility, natural appearance, and low donor site morbidity. The main limitation is unpredictable fat graft resorption, which ranges from 25% to 80%, probably as a result of ischaemia and lack of neoangiogenesis.

Based on progressive cortical thinning pathological fractures are common, and are often the presenting feature. Despite the long experience of orthopaedists, radiologists and pathologists with aneurysmal bone cyst there is limited knowledge regarding the cause of the lesion and optimal treatment.

These processes involve a series of inductive and permissive interactions that result in the determination, differentiation, and organization of craniofacial tissues. Stem cells and growth factors represent a very interesting research field for craniofacial tissues regeneration.

It has been shown that c-Jun NH(2)-terminal kinase (JNK) activation is one of the manifestations of radiation response in ATC cells.
Objective: Assessment of the effect of selective JNK inhibition on ATC cell radiosensitivity and clarification of the associated mechanisms.
