Plasma cell myeloma is a clinically heterogeneous malignancy accounting for approximately one to 2% of newly diagnosed cases of cancer worldwide. Treatment options, in addition to long-established cytotoxic drugs, include autologous stem cell transplant, immune modulators, proteasome inhibitors and monoclonal antibodies, plus further targeted therapies currently in clinical trials. Whilst treatment decisions are mostly based on a patient's age, fitness, including the presence of co-morbidities, and tumour burden, significant scope exists for better risk stratification, sub-classification of disease, and predictors of response to specific therapies...

Dental pulp is an accessible source of multipotent mesenchymal stromal cells (MSCs). The perspective role of dental pulp stem cells (DPSCs) in regenerative medicine demands an in vitro expansion and in vivo delivery which must deal with the safety issues about animal serum, usually required in cell culture practice. Human platelet lysate (PL) contains autologous growth factors and has been considered as valuable alternative to fetal bovine serum (FBS) in cell cultures. The optimum concentration to be added of such supplement is highly dependent on its preparation whose variability limits comparability of results...

The local application of bone morphogenetic protein-7 (BMP-7) in combination with the transplantation of autologous bone graft improves the outcome in nonunion treatment; however, the specific reasons remain unclear. In this study, we sought to determine if the local application of BMP-7 contributes to improved bone regeneration in nonunion therapy by modulation of the angiogenic and inflammable cytokine expression patterns of the early inflammation response. Therefore, we utilized the analysis of serological cytokine expression patterns...

Vascular progenitor cells show promise for the treatment of microvasculature endothelial injury. We investigated the function of renal artery progenitor cells derived from radical nephrectomy patients, in animal models of acute ischemic and hyperperfusion injuries. Present in human adventitia, CD34positive/CD105negative cells were clonal and expressed transcription factors Sox2/Oct4 as well as surface markers CXCR4 (CD184)/KDR(CD309) consistent with endothelial progenitor cells. Termed renal artery-derived vascular progenitor cells (RAPC), injected cells were associated with decreased serum creatinine after ischemia/reperfusion, reduced albuminuria after hyperperfusion, and improved blood flow in both models...

Neural stem cells (NSCs) have a high potency for differentiation to neurons and glial cells for replacement of damaged cells and paracrine effects for the regeneration and remyelination of host axons. Dental pulp is known to have a potential to differentiate into neural-like cells; therefore, dental pulp may be used as an autologous cell source for neural repair. In this study, we selectively expanded stem cells from human dental pulp in an initial culture using NSC media under xeno- and serum-free conditions...

The aim of this study was to isolate mesenchymal stem cells (MSCs) from feline peripheral blood (fPB-MSCs) and to characterise the cells' in vitro properties. The mononuclear cell fractions were isolated from venous blood of cats by density gradient centrifugation and cultured on plastic dishes under various culture conditions to isolate MSCs. When these cells were cultured with 5% autologous plasma (AP) and 10% foetal bovine serum (FBS), adherent spindle shaped fibroblast-like cells (fPB-MSCs) were obtained from 15/22 (68%) cats...

BACKGROUND: Despite recent advances in early detection and improvements in chemotherapy for colon cancer, the patients still face poor prognosis of postoperative recurrence and metastasis, the median survival for patients with metastatic colorectal cancer is approximately 22-24 months. Some immunotherapeutic approaches had been attempted in colon cancer patients to significantly increase overall survival. A vaccine based approach has shown a novel direction for colon cancer prevention and therapy...

PURPOSE: Aniridic keratopathy is vision-threatening condition in patients with aniridia. The keratopathy occurs due to limbal stem cell deficiency. When conventional treatments fail, surgical treatments such as corneal limbal transplantation or cultivated oral mucosal epithelium transplantation are the alternatives. Here, we report our experience with the management and monitoring of the progress of a case with aniridic keratopathy treated with a scleral lens. CASE REPORT: We describe the case of a 30-year-old woman with aniridic keratopathy in both eyes...

BACKGROUND AND OBJECTIVE: The periodontal pathogen Aggregatibacter actinomycetemcomitans has been proposed as pro-atherogenic, and complement-mediated adherence to red blood cells (RBCs) may facilitate its systemic spread. We investigated the ability of four strains of A. actinomycetemcomitans with differential expression of leukotoxin A (LtxA) and fimbriae to activate complement, adhere to RBCs and elicit cytokine responses by mononuclear cells (MNCs). MATERIAL AND METHODS: Aggregatibacter actinomycetemcomitans serotype b strains HK 921, HK 1651, HK 2092 and HK 2108 were fluorescence-labeled, incubated with human whole blood cells in the presence of autologous serum, and assessed for RBC adherence by flow cytometry and for capacity to induce cytokine production by cytometric bead array analysis...

: Transplantation of cryopreserved ovarian tissue has been shown to successfully induce pregnancies. Furthermore, puberty may be induced by transplanted ovarian tissue in girls suffering from premature primary ovarian insufficiency (PPOI) due to gonadotoxic therapy. Therefore, the question arises if ovarian tissue cryopreservation should be recommended for puberty induction in prepubertal girls with cancer prior to gonadotoxic therapies. Although this strategy seems to be more natural than administering exogenous steroid sex hormones, there are some disadvantages from the endocrinological point of view...

OBJECTIVES: The lack of specific biochemical markers is a major drawback for the diagnosis of autoimmune pancreatitis (AIP). The aims were to characterize the autoantibody profiles in AIP and pancreatic ductal adenocarcinoma (PDAC) and to identify circulating autoantibodies that could be diagnostic markers differentiating PDAC and the AIP subtypes. METHODS: Tissue lysates obtained from the resected pancreas of patients with AIP and patients with PDAC were separated by 2-dimensional polyacrylamide gel electrophoresis subsequently immunoblotted with autologous sera...

CONTEXT: Although rare, coral snake envenomation is a serious health threat in Brazil, because of the highly neurotoxic venom and the scarcely available antivenom. The major bottleneck for antivenom production is the low availability of venom. Furthermore, the available serum is not effective against all coral snake species found in Brazil. An alternative to circumvent the lack of venom for serum production and the restricted protection of the actually available antivenom would be of great value...

Acute kidney injury and long-term renal dysfunction are common problems following bone morrow transplantation (BMT) and highly related to mortality. The frequency and risk of renal dysfunction are directly related to the method of BMT, with myeloablative allogeneic BMT being associated to the highest risk followed by non-myeloablative allogeneic and myeloablative autologous BMT. The type of BMT is, thus, more important than co-factors such as advanced age, comorbidities, or high baseline serum creatinine. The causes for renal failure are multiple and include chemotherapy and high-dose radiation with fluid loss by diarrhea or vomiting, sepsis or nephrotoxic drugs such as calcineurin inhibitors and antimicrobials...

Immunoglobulin (Ig)D-κ multiple myeloma (MM) is a rare neoplastic disease characterized by an aggressive and rapidly progressing course, which constitutes only a very small proportion of all MM cases. In the present report, the clinical case of a 51-year-old Caucasian woman diagnosed with IgD-κ MM is described. The patient underwent different chemotherapeutic treatments subsequently to a single autologous stem cell transplantation. Despite the inherent difficulty of monitoring IgD levels and performing serum immunofixation electrophoresis, the clinical outcome of the patient was almost uniquely monitored by measuring the levels of κ and λ free light chains (FLCs) and total heavy chain IgD...

For many years, sweat has been recognized as an exacerbation factor in all age groups of atopic dermatitis (AD) and a trigger of cholinergic urticaria (CholU). Recently, we reported the improvement of AD symptoms by spray with tannic acid, which suppresses basophil histamine release by semipurified sweat antigens in vitro, and showering that removes antigens in sweat from the skin surface. We finally identified MGL_1304 secreted by Malassezia globosa as a major histamine-releasing antigen in human sweat. MGL_1304 is detected as a 17-kDa protein in sweat and exhibits almost the highest histamine-release ability from basophils of patients with AD and CholU among antigens derived from Malassezia species...

PURPOSE: Chronic spontaneous urticaria (CSU) is a disease that is primarily seen in adults and is comparatively rare in children. Consequently, only a few studies have focused on the pathogenesis of the disease in children. This study investigated the possible role of metalloproteinase-9 (MMP-9) in the pathogenesis of CSU in children. METHODS: The study group was composed of 54 children with CSU; 34 healthy children comprised the control group. The demographic and clinical features of the study group were extensively evaluated, and laboratory assessments were also performed...

Long-term dietary and pharmacological treatments for obesity have been questioned, particularly in individuals with severe obesity, so a new approach may involve adipose tissue transplants, particularly autologous transplants. Thus, the aim of this study was to evaluate the metabolic effects of autologous subcutaneous adipose tissue (SAT) transplants into two specific intraabdominal cavity sites (omental and retroperitoneal) after 90 days. The study was performed using two different diet-induced obesity (DIO) rat models: one using a high-fat diet (HFD) and the other using a high-carbohydrate diet (HCHD)...
