Duplication of the odontoid process remains a rare developmental pathology that is underrepresented in the current literature. As the pivot point for the craniovertebral junction, the odontoid process is vital for the integrity of the atlanto-axial joint and the ability of the head and cervical spine to rotate correctly. The pathogenesis being incompletely understood, it has been proposed that odontoid process duplication involves faulty sclerotome migration and disruption of the axis ossification center. Patients presenting with this pathology usually have associated structural abnormalities. A detailed anatomical and embryological understanding of the odontoid process is necessary for successful management and treatment of patients presenting with odontoid process duplication. We present a rare case of a patient with a duplicated odontoid process in association with C2-C3 fusion, incomplete anterior arch of C1, variant inferior bony process of the transverse process of C1, and enlarged right jugular foramen.This study aimed to investigate whether the antidiabetic drugs dipeptidyl peptidase 4 (DPP4) inhibitors such as evogliptin and sitagliptin affect the membrane DPP4 (mDPP4) enzymatic activity and immune function of T helper1 (Th1) cells in terms of cytokine expression and cell profiles. The mDPP4 enzymatic activity, cytokine expression, and cell profiles, including cell counts, cell viability, DNA synthesis, and apoptosis, were measured in pokeweed mitogen (PWM)-activated CD4+CD26+ H9 Th1 cells with or without the DPP4 inhibitors, evogliptin and sitagliptin. PWM treatment alone strongly stimulated the expression of mDPP4 and cytokines such as interleukin (IL)-2, IL-10, tumor necrosis factor-alpha, interferon-gamma, IL-13, and granulocyte-macrophage colony stimulating factor in the CD4+CD26+ H9 Th1 cells. Evogliptin or sitagliptin treatment potently inhibited mDPP4 activity in a dose-dependent manner but did not affect either the cytokine profile or cell viability in PWM-activated CD4+CD26+ H9 Th1 cells. These results suggest that, following immune stimulation, Th1 cell signaling pathways for cytokine expression function normally after treatment with evogliptin or sitagliptin, which efficiently inhibit mDPP4 enzymatic activity in Th1 cells.Transforming growth factor-β1 (TGF-β1) regulates wound healing/regeneration and aging processes. Dental pulp stem cells from human exfoliated deciduous teeth (SHED) are cell sources for treatment of age-related disorders. We studied the effect of TGF-β1 on SHED and related signaling. SHED were treated with TGF-β1 with/without pretreatment/co-incubation by SB431542, U0126, 5Z-7-oxozeaenol or SB203580. Sircol collagen assay, 3-(4,5-Dimethylthiazol-2-yl)-2,5- diphenyl tetrazolium bromide (MTT) assay, alkaline phosphatase (ALP) assay, RT-PCR, western blotting and PathScan phospho-ELISA were used to measure the effects. We found that SHED expressed ALK1, ALK3, ALK5, TGF-RII, betaglycan and endoglin mRNA. TGF-β1 stimulated p-Smad2, p-TAK1, p-ERK, p-p38 and cyclooxygenase-2 (COX-2) protein expression. It enhanced proliferation and collagen content of SHED that were attenuated by SB431542, 5Z-7-oxozeaenol and SB203580, but not U0126. TGF-β1 (0.5-1 ng/ml) stimulated ALP of SHED, whereas 5-10 ng/ml TGF-β1 suppressed ALP. SB431542 reversed the effects of TGF-β1. However, 5Z-7-oxozeaenol, SB203580 and U0126 only reversed the stimulatory effect of TGF-β1 on ALP. Four inhibitors attenuated TGF-β1-induced COX-2 expression. TGF-β1-stimulated TIMP-1 and N-cadherin was inhibited by SB431542 and 5Z-7-oxozeaenol. These results indicate that TGF-β1 affects SHED by differential regulation of ALK5/Smad2/3, TAK1, p38 and MEK/ERK. TGF-β1 and SHED could potentially be used for tissue engineering/regeneration and treatment of age-related diseases.The vast majority of hip or knee arthroplasty finishes with improved limb functional status. Despite this, some patients do not recover; they "save" the operated limb; they cannot trust it. This also happens in patients whose range of motion and muscle strength are rated as very good. It is possible, therefore, that the causes must be located in the movement initiating centre, in the motor cortex. We can link the activation and changes in the metabolism of the cerebral cortex, e.g. during limb movement, with the changes in bioelectrical activity visible in electroencephalography (EEG). Conclusions Our literature analysis shows that so far, no study has been conducted to check whether EEG activity changes over the sensory-motor region after lower limb arthroplasty. We propose the design of such a study with an analysis of potential difficulties that would have to be overcome by the team undertaking the challenge. The obtained data could be the basis for neurorehabilitation using the EEG biofeedback method. Effective interventions would further improve the quality of life. The aim To draw attention to the need for careful analysis of patients with epilepsy in terms of the possibility of co-occurring arrhythmia. Material and methods Analysis of video-EEG registration in the inter-seizure period in a patient with diagnosed epilepsy. Case study The authors present a 33-year-old patient with generalised epilepsy of unknown etiology diagnosed in childhood. In this subject, generalised seizure discharges without clinical manifestation of epileptic seizure and with concomitant cardiac arrhythmias in the form of atrial fibrillation were recorded during video-EEG registration. This was carried out during the patient's of hospitalisation at the neurology ward. Conclusions The case study presented is as an example of existing complex and not fully understood interactions between epilepsy and arrhythmia. A mutation within the SCN1B encoding genes, which is responsible for channelopathy within the voltage-dependent Nav sodium channels, may be considered as a potential cause for this state. However, further analysis and research is needed that would eventually allow to find out the reason for these relationships.Conclusions The case study presented is as an example of existing complex and not fully understood interactions between epilepsy and arrhythmia.
