Gut microbiota is known to play a main role in regulating both health and disease in humans. Strategies for the therapeutic modulation of gut microbiota are therefore expected to give a relevant contribution in the management of disorders associated with its impairment. Among these options, one of the most renowned is fecal microbiota transplantation (FMT). A growing body of evidence showed clearly that FMT is an effective treatment against recurrent Clostridium difficile infection. Moreover, it was shown to be a promising therapy for the management of several noncommunicable disorders, including inflammatory bowel diseases and metabolic disorders...

Invasive fungal diseases are important clinical problems that are often complicated by severe illness and therefore the inability to use invasive measures to definitively diagnose the disease. Tests for a range of fungal biomarkers that do not require an invasive sample-collection procedure have been incorporated into adult clinical practice, but pediatric data and pediatric-specific recommendations for some of these diagnostic tools are lacking. In this review, we summarize the published literature and contemporary strategies for using the biomarkers galactomannan, (1→3)-β-d-glucan, Candida mannan antigen and anti-mannan antibody, and fungal polymerase chain reaction for diagnosing invasive fungal disease in children...

Considerable progress has been made in the prevention, diagnosis, and management of pediatric patients with invasive fungal disease (IFD). The reported decreasing trend in the incidence of invasive candidiasis (IC) over the past 15 years in both neonates and children has been encouraging. Nevertheless, due to the growing number of immunocompromised children at risk for IFD, this disease continues to be associated with significant morbidity and death and with increased financial burden to the health care system...

In patients with diffuse large B-cell lymphoma (DLBCL) classified as high-intermediate risk or high risk using the International Prognosis Index, the efficacy of high-dose chemotherapy combined with upfront autologous stem cell transplantation (HDT/ASCT) remains controversial in the rituximab era. In the present study, 27 patients who had been treated with HDT/ASCT in an upfront setting were retrospectively analyzed, and compared with 77 patients with similar characteristics who had received conventional chemotherapy without HDT/ASCT (the non-upfront setting)...

Atypical chronic myeloid leukemia (aCML) is a rare subtype of myelodysplastic/myeloproliferative neoplasm (MDS/MPN). Although recurrent chromosomal and genetic abnormalities are frequently observed in aCML, none are specific to this type of leukemia. The present study reported a case of aCML associated with i(X)(p10), a rare recurrent chromosomal abnormality of hematological malignancy. A 40-year-old female was referred to the Tokyo Medical and Dental University Hospital (Tokyo, Japan) due to slight leukocytosis and anemia...

Pancreatic ductal carcinoma (PDC) is one of the major causes of cancer-associated mortality globally due to its high potential for distant metastasis. To understand hematogenous metastasis, the molecular expression profiles of weak metastatic PDC cell subline BxPC-3 and highly liver-metastatic cell subline LM-BxPC-3 were compared, and zinc finger protein 185 (ZNF185) was identified as a molecule that is upregulated in LM-BxPC-3 cells. The aim of the present study was to evaluate the clinicopathological significance of ZNF185 in PDC...

Programmed cell death 4 (PDCD4) is known to suppress neoplastic transformation, cell proliferation and metastasis, and to be downregulated by microRNA-21 (miR-21) in renal cell carcinoma (RCC) cell lines and tissues. The aim of the present study was to investigate the roles of and association between PDCD4 and miR-21 in a nude mouse renal cancer model. A total of 24 BALB/c male nude mice were randomly assigned into the following three groups: Negative control (NC; n=8), miR-21 inhibitor (n=8) and miR-21 mimic (n=8)...

Previous studies have demonstrated that DNA methyltransferase 1 (DNMT1) is required for the maintenance of DNA methylation and epigenetic changes that may lead to the development of esophageal squamous cell carcinoma (ESCC). In order to investigate whether the silencing of DNMT1 protects tumor suppressor genes, including p16, and is able to be used as a potential therapy for human ESCC, short hairpin RNA targeting DNMT1 (shRNA-DNMT1) was synthesized and transfected into the human ESCC lines KYSE150 and KYSE410, which were then injected into the backs of nude mice prior to harvesting...

Vitamin D has been recommended as an immune modulator in recent years, in addition to regulating calcium-phosphorous-bone metabolism. Clinical studies on organ transplantation found that vitamin D sufficiency patients were less likely to develop acute cellular rejection within one year after transplantation compared to those with vitamin D deficiency. Thus, a high percentage of regulatory T cells might play a key role in preventing acute cellular rejection (ACR). In this report, we studied the specific effects of 1,25(OH)2D3 on human T cell diff ;erentiation, and determined the potential molecule mechanism behind...

INTRODUCTION: Cell transplantation is an innovative therapeutic approach after brain injury to compensate for tissue damage. To have real-time longitudinal monitoring of intracerebrally grafted cells, we explored the feasibility of a molecular imaging approach using thymidine kinase HSV1-TK gene encoding and [18F]FHBG as a reporter probe to image enzyme expression. METHODS: A stable neuronal cell line expressing HSV1-TK was developed with an optimised mammalian expression vector to ensure long-term transgene expression...

BACKGROUND: Current data regarding the outcome of kidney transplantation in patients with familial Mediterranean fever (FMF) who reach end-stage renal disease (ESRD) due to reactive amyloidosis A (AA) are scarce and inconclusive. METHODS: The outcomes of 20 patients with FMF and biopsy-proven AA amyloidosis that were transplanted between 1995 and 2014 were compared with 82 control patients (32 with diabetes mellitus and 50 with nondiabetic kidney disease). Major outcome data included overall patient and graft survivals...

BACKGROUND: Immunosuppression therapy after lung transplantation fails to prevent bronchiolitis obliterans syndrome (BOS) in many patients, primarily a disease of the small airways. We have reported that BOS is associated with a lack of suppression of cytotoxic mediators, and proinflammatory cytokines, in peripheral blood T, NKT-like (particularly CD8+) and NK cells. We also showed a loss of glucocorticoid receptor (GCR) in proinflammatory lymphocytes after transplant. It is unknown whether these proinflammatory lymphocytes target the small and/or large airways in BOS...

The immune system is characterized by the generation of structurally and functionally heterogeneous immune cells that constitute complex innate and adaptive immunity. This heterogeneity of immune cells results from changes in the expression of genes without altering DNA sequence. To achieve this heterogeneity, immune cells orchestrate the expression and functional status of transcription factor (TF) networks, which can be broadly categorized into 3 classes: pioneer TFs that facilitate initial commitment and differentiation of hematopoietic cells, subset-specific TFs that promote the generation of selected cell lineages, and immune-signaling TFs that regulate specialized function in differentiated cells...

BACKGROUND: The early impact of renal transplantation on subclinical cardiovascular measures in pediatric patients has not been widely investigated. This analysis is performed for pediatric patients participating in the prospective 4C study and focuses on the early effects of RRT modality on cardiovascular comorbidity in patients receiving a preemptive transplant or started on dialysis. METHODS: We compared measures indicating subclinical cardiovascular organ damage (aortal pulse wave velocity, carotid intima media thickness, left ventricular mass index) and evaluated cardiovascular risk factors in 166 pediatric patients before and 6 to 18 months after start of RRT (n=76 transplantation, n=90 dialysis)...
