Background/aims: Periosteal tissue is a valuable source of multipotent stem cells for bone tissue engineering. To characterize these cells in detail, we generated an immortalized human cranial periosteal cell line and observed an increased MSCA-1 and CD146 expression, as well as an earlier and stronger mineralization compared to the parental cells. Further, we detected a higher osteogenic potential of MSCA-1high compared to MSCA-1low cranial periosteal cell (CPC) fractions. Read More

Objective:: CBCT often use a smaller field of view compared to conventional CT scans. This might lead to a wrong field of view with the need for secondary exposure ("retakes"). The purpose of this retrospective study was to assess the frequency of re-exposures in cone beam computed tomography (CBCT) and to identify whether the parameters age, gender and FOV have an influence on the re-exposure of the patient.

The article presents an original analysis which combines use-wear, 3D modelling and spatial analyses to experimental archaeology in order to investigate Early Upper Palaeolithic flint-knapping gestures and techniques involving the use of macro-lithic tools. In particular, the methodological framework proposed in this paper was applied to the study of Protoaurignacian and Aurignacian macro-tools from Fumane Cave (Verona, Italy). Combining spatial analysis and use wear investigation, both at low and high magnifications, permitted the identification and detailed description of the use-related traces affecting both the hammerstones and retouchers which, at Fumane Cave, were used at different stages during flint tool production.

Introduction: Botulinum neurotoxin A (BoNT-A) is a minimally invasive and technically straightforward treatment of masseter muscle (MM) volume reduction and facial contouring, but the literature on its long-term effect on MM volume remains unclear.

Objective: This study aimed to assess quantitatively for progressive volume changes of lower facial contour after 3 BoNT-A injections in patients with bilateral MM hypertrophy causing square facial morphology using 3-dimensional computed tomographic scans.

Materials And Methods: Ten female patients with square facial morphology due to bilateral MM hypertrophy were recruited to, and 6 completed, this clinical study. Read More

This study evaluated the effect of ultraviolet functionalization (UV) on bone integration ability in rabbit model, using epifluorescence microscopy. Each of twelve rabbits (n=6) received randomly four titanium domes prepared with or without ultraviolet for 48 hours (UVC,λ= 250 ± 20 nm; Philips, Tokyo, Japan): (1) turned surface (T), (2) turned surface with UV(T-UV), (3) sandblasted (120 μm aluminum oxide) and etched by 18% hydrochloric acid and 49% sulphuric acid at 60°C for 30 min (SLA) and (4) SLA surface with UV(SLA-UV). Fluorochrome bone labels were marked by oxytetracycline at 25 mg/kg on 13th days and 14th days and calcein at 5 mg/kg on 3th days and 4th days before euthanization. Read More

Purpose Of The Study: Körner's septum (KS) is a developmental remnant formed at the junction of mastoid and temporal squama, representing the persistence of the petrosquamosal suture. During mastoid surgery, it could be taken as a false medial wall of the antrum so that the deeper cells might not be explored. The aim of the study was to assess a Körner's septum prevalence and to analyze its topography. Read More

Background: After the resection at the mandibular site involving oral cancer, free vascularized fibular graft, a type of vascularized autograft, is often used for the mandibular reconstruction. Titanium mesh (T-mesh) and particulate cancellous bone and marrow (PCBM), however, a type of non-vascularized autograft, can also be used for the reconstruction. With the T-mesh applied even in the chin and angle areas, an aesthetic contour with adequate strength and stable fixation can be achieved, and the pores of the mesh will allow the rapid revascularization of the bone graft site.

Fibrous dysplasia is a benign fibro-osseous disease of the bone, which is most commonly associated with congenital mutations in cAMP regulating protein Gsα coded by gene. Often it is seen involving the craniofacial skeleton and can range from an asymptomatic monostotic form to polyostotic variant involving almost all the bones of the skull, thereby leading to functional and esthetic problems. This requires a continuous monitoring of the involved region throughout the life of the patient, even after the surgical interventions. Read More

Background: Epithelioid cell granuloma with caseating necrosis is a typical pathological finding in tuberculosis. While specific inflammation, including that related to tuberculosis, can induce caseating granuloma formation, there have been very few reports on the induction of caseating granuloma by non-specific inflammation. Chronic periapical periodontitis is usually related to bacterial biofilm formation as well as fungal or viral infection in the periapical lesion. Read More

Toll-like receptor 8 (TLR8), a sensor for pathogen-derived single-stranded RNA (ssRNA), binds to uridine (Uri) and ssRNA to induce defense responses. We here show that cytidine (Cyd) with ssRNA also activated TLR8 in peripheral blood leukocytes (PBLs) and a myeloid cell line U937, but not in an embryonic kidney cell line 293T. Cyd deaminase (CDA), an enzyme highly expressed in leukocytes, deaminates Cyd to Uri. Read More

Motivation: Single-cell transcriptomic data are commonly accompanied by extremely high technical noise due to the low RNA concentrations from individual cells. Precise identification of differentially expressed genes and cell populations are heavily dependent on the effective reduction of technical noise, for example, by gene filtering. However, there is still no well-established standard in the current approaches of gene filtering. Read More

Pilomatricoma is a benign skin tumor originating from the matrix cells of the hair follicles. Sometimes, its diagnosis can be difficult, especially in the preauricular region, where in the differential diagnosis, in addition to other dermal and subcutaneous masses, primary and secondary parotid gland tumor lesions must be also considered. A 34-year-old female was referred to our Institution with a right preauricular swelling over 12 months, which enlarged in the last two months. Read More

Matrix metalloproteinases (MMPs), endopeptidases with diverse biochemical functions, can promote cancer cell invasion and metastasis by degrading the extracellular matrix. A high matrix metalloproteinase-14 (MMP-14) expression in gastric cancer tissue has been associated with metastasis and poor prognosis. To further understand this association, we investigated serum MMP-14 as a biomarker in gastric cancer patients. Read More

The reconstruction of orbital-maxillary-zygomatic complex (OMZC) on patients suffering from trauma and space-occupying lesions is challenging due to the irregularity of craniomaxillofacial bones. To overcome the challenge in precise OMZC reconstruction, individual three-dimensional (3D) disease models and mirror-imaged 3D reconstruction models were printed on the basis of the computer tomography. Preoperative planning by rehearsing surgical procedures was made on the 3D disease models and the scaffolds including titanium and absorbable meshes or plates were anatomically premolded using the mirror-imaged 3D models as guide.
