In the present report, we have generated osteoblast-like cells derived from mouse induced-pluripotent stem (iPS) cells on PLGA with osteoinduction medium in vitro and in vivo. The cell culture period was 2 weeks. At 2 weeks, mRNA level of type I collagen was significantly higher than at 1 week. Osteocalcin mRNA level at 2 weeks was tendency to increase compared with at 1 week. And the cells cultured on PLGA were positive for immunofluorescent staining of osteocalcin and alizarin red S staining. The scaffold and osteogenic-like cells induced in vitro were implanted subcutaneously into SCID mice...

BACKGROUND: Current categorical classification of personality disorders has been criticized for overlooking the dimensional nature of personality and that it may miss some sub-threshold personality disturbances of clinical significance. We aimed to evaluate the clinical importance of these conditions. For this, we used a simple four-level dimensional categorization based on the severity of personality disturbance. METHODS: The sample consisted of 352 patients admitted to mental health services...

Xenograft models are transforming our understanding of the output capabilities of primitive human hematopoietic cells in vivo. However, many variables that affect post-transplant reconstitution dynamics remain poorly understood. Here we show an equivalent level of human chimerism can be regenerated from human CD34(+) cord blood cells transplanted intravenously either with or without additional radiation-inactivated cells into 2-6 month-old NOD-Rag1(-/-)-IL2Rγc(-/-) (NRG) mice given a more radioprotective conditioning regimen than is possible in conventionally used, repair-deficient, NOD-Prkdc(scid/scid)-IL2Rγc(-/-) (NSG) hosts...

BACKGROUND/AIM: In prevailing opinion, a strong relation exists between lack of empathy and antisocial personality disorder (ASPD). However, recent data fail to wholly clarify this relation, especially in consideration of empathy dimensions. In this study our aim was to address ASPD and social functionality from a contextual behavioral science viewpoint. MATERIALS AND METHODS: The present study was conducted with a sample of 34 individuals with ASPD and 32 healthy individuals as the control group...

The Brief Symptom Inventory-18 (BSI-18) is widely used to assess psychological symptoms in cancer survivors, but the validity of conventional BSI-18 cut-off scores in this population has been questioned. This study assessed the accuracy of the BSI-18 for identifying significant anxiety and depression in young adult cancer survivors (YACS), by comparing it with a "gold standard" diagnostic interview measure. Two hundred fifty YACS, age 18-40 completed the BSI-18 and the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (DSM-IV; SCID) interview assessing anxiety and depressive disorders...

Gene repair of CD34(+) hematopoietic stem and progenitor cells (HSPCs) may avoid problems associated with gene therapy, such as vector-related mutagenesis and dysregulated transgene expression. We used CRISPR (clustered regularly interspaced short palindromic repeat)/Cas9 (CRISPR-associated 9) to repair a mutation in the CYBB gene of CD34(+) HSPCs from patients with the immunodeficiency disorder X-linked chronic granulomatous disease (X-CGD). Sequence-confirmed repair of >20% of HSPCs from X-CGD patients restored the function of NADPH (nicotinamide adenine dinucleotide phosphate) oxidase and superoxide radical production in myeloid cells differentiated from these progenitor cells in vitro...

Epidemiologic studies indicate the use of either statins or aspirin have beneficial effects in prostate cancer patients. The present study was undertaken to evaluate the effects and mechanisms of atorvastatin and aspirin alone or in combination in human prostate cancer cells cultured in vitro and grown as xenograft tumors in severe combined immune-deficient (SCID) mice. The growth and apoptosis in prostate cancer cells were determined by the trypan blue exclusion and propidium iodide staining assays. Activation of the nuclear factor κB (NF-κB) was measured by luciferase reporter assay, and the levels of phospho-signal transducer and activator of transcription (Stat)3 and phospho-extracellular signal-regulated kinase (Erk)1/2 were determined by western blot analysis...

Adenosine Deaminase (ADA) deficiency is an autosomal recessive variant of severe combined immunodeficiency (SCID) caused by systemic accumulation of ADA substrates. Neurological and behavioral abnormalities observed in ADA-SCID patients surviving after stem cell transplantation or gene therapy represent an unresolved enigma in the field. We found significant neurological and cognitive alterations in untreated ADA-SCID patients as well as in two groups of patients after short- and long-term enzyme replacement therapy with PEG-ADA...

We have previously reported that the negative regulator Similar Expression to FGF (hSef) is down-regulated in prostate cancer and its loss is associated with clinical metastasis. Here, we explored the mechanistic basis of this finding. We first confirmed our clinical observation by testing hSef manipulation in an in vivo metastasis model. hSef stable expressing cells (PC3M-hSef) or empty vector controls (PC3M-EV) were injected subcutaneously into the lateral thoracic walls of NOD-SCID gamma mice and lungs were harvested at autopsy...

Stem cells are emerging as a promising new treatment modality for a variety of central nervous system disorders. However, their use is hampered by the potential for the development of teratomas and other tumors. Therefore, there is a crucial need for the development of methods for detecting teratomas in preclinical safety studies. The aim of the current study is to assess the ability of a compact Magnetic Resonance Imaging (MRI) system to detect teratoma formation in mice. Five NOD-SCID mice were injected intrathecally with human embryonic stem cells (hESCs), with two mice serving as controls...

Severe combined immunodeficiency (SCID) is 1 of the most common indications for pediatric hematopoietic cell transplantation (HCT) in patients with primary immunodeficiency. Historically, SCID was diagnosed in infants who presented with opportunistic infections within the first year of life. With newborn screening (NBS) for SCID in most of the United States, the majority of infants with SCID are now diagnosed and treated in the first 3.5 months of life; however, in the rest of the world, the lack of NBS means that most infants with SCID still present with infections...

OBJECTIVE: Side effects to antidepressant medication can affect the efficacy of treatment, but few predictors foretell who experiences side effects and which side effects they experience. This secondary data analysis examined whether depressed patients with comorbid panic disorder were more likely to experience side effects than those without panic disorder. The study also examined whether greater burden of side effects predicted a poorer treatment course for patients with panic disorder than those without panic disorder...

Burkholderia pseudomallei is the causative agent of melioidosis, an infectious disease with high incidence and mortality in South East Asia and Northern Australia. To date there is no protective vaccine and antibiotic treatment is prolonged and not always effective. Most people living in endemic areas have been exposed to the bacteria and have developed some immunity, which may have helped prevent disease. Here, we used a humanized mouse model (hu-PBL-SCID), reconstituted with human peripheral blood mononuclear cells (PBMCs) from seropositive donors, to illustrate the potential of three known antigens (FliC, OmpA and N-PilO2) for boosting both T- and B-cell immune responses...

Psoriasis is a chronic autoimmune skin disease affecting approximately 2 % of the population with a major psychosocial and socioeconomic impact. A causal therapy leading to permanent cure is not available, and current treatments only lead to limited amelioration, and therefore new therapeutic targets need to be identified. Recent works demonstrated a predominant role of TH17 cells in the pathogenesis of psoriasis; yet the underlying molecular mechanisms driving the development of the disease are still largely elusive...

Epidemiologic and systematic studies have indicated that flavonoid consumption is associated with a lower incidence of breast cancer. Baicalein is the primary flavonoid derived from the roots of Scutellaria baicalensis Georgi. In the current study, the long-term exposure of breast epithelial cells to 17β-estradiol (E2) was used to investigate the chemopreventive potential of baicalein on neoplastic transformation. The results demonstrated that baicalein significantly inhibited E2-induced cell growth, motility, and invasiveness, and suppressed E2-induced misshapen acini formation in 3D cultures...

Angiogenesis is the process by which new blood vessels are formed from existing vessels. New vessel growth requires coordinated endothelial cell proliferation, migration, and alignment to form tubular structures followed by recruitment of pericytes to provide mural support and facilitate vessel maturation. Current in vitro cell culture approaches cannot fully reproduce the complex biological environment where endothelial cells and pericytes interact to produce functional vessels. We present a novel application of the in vivo matrix gel plug assay to study endothelial-pericyte interactions and formation of functional blood vessels using severe combined immune deficiency mutation (SCID) mice...

Hypoxia has been implicated in the metastasis of Ewing sarcoma (ES) by clinical observations and in vitro data, yet direct evidence for its pro-metastatic effect is lacking and the exact mechanisms of its action are unclear. Here, we report an animal model that allows for direct testing of the effects of tumor hypoxia on ES dissemination and investigation into the underlying pathways involved. This approach combines two well-established experimental strategies, orthotopic xenografting of ES cells and femoral artery ligation (FAL), which induces hindlimb ischemia...

OBJECTIVE: Depression has been traditionally explored in the context of multiple sclerosis (MS) as a binary construct (depressed, not depressed). However, given the 50% lifetime prevalence rate of depression in MS, it may be useful to consider not only currently depressed versus nondepressed patients, but to evaluate groups that better characterize the complexity of MS depression. The objective of the current study was to examine demographic, cognitive, illness, and psychosocial variables thought to associate with depression in MS across 3 groups: currently depressed, remitted depression, and never been depressed...
