Offspring growth requires establishing maternal behavior associated with the maternal endocrine profile. Placentae support the adaptations of the mother, producing bioactive molecules that affect maternal organs. We recently reported that placentae produce superoxide dismutase 3 (SOD3) that exerts sustained effects on the offspring liver via epigenetic modifications.

The mesenchymal stem cell (MSC)-conditioned medium (CM), called secretome, contains many proteins and growth factors required for tissue repair and growth. This study evaluated the bioactivity of a bovine bone scaffold combined with the secretome of human umbilical cord MSCs (hUC-MSCs) by analyzing MC3T3-E1 cell adhesion and viability on the scaffold.

Hes1 is a transcriptional regulator with basic helix-loop-helix (bHLH) domain and is a well-known Notch effector. In this study, we investigated the functional roles of early induction of Hes1 by BMP9 in a mouse mesenchymal stem cell line, ST2.

It thus requires a careful and precise examination to establish a diagnosis. A surgical procedure of the parotid gland is challenging due to the associated risk factor of facial nerve injury.

The current study is aiming to systematically review the impact of coffee consumption on periodontal health status. An article search was carried out in two electronic databases (PUBMED and Web of Sciences).

Design: Clinical, retrospective, comparative, methodological study.
Patients/participants: Twenty patients with UCLP were selected after a review of the records.
Bone homeostasis is regulated by bone morphogenic proteins (BMPs), among which BMP9 is one of the most osteogenic. Here, we have found that BMP9 rapidly increases the protein expression of hypoxia-inducible factor-1α (HIF-1α) in osteoblasts under normoxic conditions more efficiently than BMP2 or BMP4. A combination of BMP9 and hypoxia further increased HIF-1α protein expression.

However, this procedure can be associated with many postoperative complications including persistent pain, swelling, trismus, and paresthesia due to nerve injury. This study aimed to identify the correlation of postoperative complications with patient's age, sex, and surgical difficulty level.

An accurate assessment of the maxillary canine's position can help determine the severity of the impaction, the difficulty of therapy, and the treatment's prognosis.
Materials And Methods: A total of 55 impacted canines were studied and selected retrospectively.
The aim of this retrospective cohort study was to compare the recurrence rate and speech outcomes between two techniques for palatal fistula closure of cleft palate (CP). Patients with CP who underwent secondary palatal fistula closure using the single hinge-flap method with double-breasted mattress suture (hinge-flap group) and those who were treated with the conventional sliding palatal flap method (sliding-flap group) were retrospectively evaluated for demographic and perioperative variables. Recurrence rate of palatal fistula, perceptual speech outcomes, and nasalance scores were further reviewed in patients who met the inclusion criteria.

Demineralized freeze-dried bovine bone xenograft (DFDBBX) particle is being developed as a novel xenogeneic bone filler.
Objectives: The study aimed to analyze osteogenic activity and bone-forming capacity of DFDBBX particles compared to DBBM particles in alveolar bone defects in rabbit mandibles models.
Ultraviolet radiation is one of the standard treatment selections for psoriasis. interferon (IFN)-γ and IFN-γ-induced CXCL10, which are highly expressed by keratinocytes in psoriasis lesion, are therapeutic targets for psoriasis. In this study, we found that ultraviolet B (UVB) irradiation inhibited IFN-γ signaling events, including STAT1 phosphorylation and induction of CXCL10 messenger RNA (mRNA) expression in keratinocytes.

Similarly, local dysregulation of adipocytokine secretion is an initial event in the deleterious effects of obesity on metabolism. We previously reported that CXCL13 is highly produced during adipogenesis, however little is known about the roles of CXCL13 in adipocytes.
View Article and Find Full Text PDFOsteopontin (OPN) is an osteoblast-derived secretory protein that plays a role in bone remodeling, osteoblast responsiveness, and inflammation. We recently found that osteoblast differentiation is type-specific, with conditions of JNK inactivation inducing osteoblasts that preferentially express OPN (OPN-type). Since OPN-type osteoblasts highly express osteogenesis-inhibiting proteins and Rankl, an important inducer of osteoclastogenesis, an increased appearance of OPN-type osteoblasts may be associated with inefficient and poor-quality bone regeneration.
View Article and Find Full Text PDFBone morphogenetic protein (BMP)9 has been reported to be the most potent BMP to induce bone formation. However, the details of BMP9-transduced intracellular signaling remain ambiguous. Here, we have investigated signal transduction mechanisms of BMP9 in comparison to BMP2, another potent inducer of bone formation, in osteoblasts.
View Article and Find Full Text PDFOsteoblasts are versatile cells involved in multiple whole-body processes, including bone formation and immune response. Secretory amounts and patterns of osteoblast-derived proteins such as osteopontin (OPN) and osteocalcin (OCN) modulate osteoblast function. However, the regulatory mechanism of OPN and OCN expression remains unknown.

The objective was to analyze the effect of the additional basal view (BV) feature on the reliability of the AY method for Japanese children with complete cleft lip and palate (CUCLP).
Design: Blind retrospective analysis of clinical records on 43 patients (5- to 7-year-old) with nonsyndromic CUCLP who underwent primary lip repair from 2005 to 2011.
Objective: To visualize and quantitatively analyze facial surface asymmetry following primary cleft lip repair in patients with unilateral cleft lip and palate (UCLP) and to compare this with noncleft controls.
Design: Retrospective comparative study.
Patients: Twenty-two patients with complete UCLP who underwent primary lip repair from 2009 to 2013 were enrolled in this study.
Adipogenic differentiation plays a vital role in energy homeostasis and endocrine system. Several transcription factors, including peroxisome proliferator-activated receptor gamma 2 and CCAAT-enhancer-binding protein (C/EBP) α, β, and δ, are important for the process, whereas the stage-specific intracellular signal transduction regulating the onset of adipogenesis remains enigmatic. Here, we explored the functional role of c- N-terminal kinases (JNKs) in adipogenic differentiation using differentiation models of 3T3-L1 cells and primary adipo-progenitor cells.
