It has been widely suggested that invasion success along broad environmental gradients may be partially due to phenotypic plasticity, but rapid evolution could also be a relevant factor for invasions. Seed and fruit traits can be relevant for plant invasiveness since they are related to dispersal, germination, and fitness. Some seed traits vary along environmental gradients and can be heritable, with the potential to evolve by means of natural selection. Utilizing cross-latitude and reciprocal-transplant experiments, we evaluated the adaptive value of seed thickness as assessed by survival and biomass accumulation in Taraxacum officinale plants...

BACKGROUND AND PURPOSE: In BALB/c mice with transplantable breast tumors, we showed that CD200R1KO mice were cured of local and metastatic growth of EMT6 cells following surgical resection of localized tumor and immunization with irradiated cells along with CpG as adjuvant. On the other hand, wild-type (WT) animals treated in the same fashion develop pulmonary and liver metastases within 20 days of surgery. To develop an in vitro system which would mimic the in vivo model and allow exploration of factors controlling tumor invasion as a precursor to in vivo metastasis, we have developed and characterized a two-phase culture system...

Transplantation of in vitro expanded human corneal endothelial precursors (HCEP) cells using a nanocomposite (D25-NC) gel sheet as supporting material in bovine's cornea has been earlier reported. Herein we report the transplantation of HCEP cells derived from a cadaver donor cornea to three patients using the NC gel sheet. In three patients with bullous keratopathy, one after cataract surgery, one after trauma and another in the corneal graft, earlier performed for congenital corneal dystrophy, not amenable to medical management HCEP cells isolated from a human cadaver donor cornea in vitro expanded using a thermoreversible gelation polymer (TGP) for 26 days were divided into three equal portions and 1...

Massive hemoptysis occurs in a minority of patients with cystic fibrosis, with an annual incidence of 1%. Although rare, massive hemoptysis can be a severe and potentially fatal complication of this disease. Beyond the acute life-threatening event, hemoptysis in patients with cystic fibrosis has been associated with faster decline in lung function, accelerated need for lung transplant, and increased mortality. The bronchial arteries are the culprit vessels in over 90% of cases of hemoptysis. This normally quiescent vascular system undergoes remarkable hypertrophy, collateralization, and angiogenesis before the onset of hemoptysis, introducing numerous pitfalls for the interventionalist...

OBJECTIVES: Cutaneous warts represent a major problem in organ transplant recipients because of their extensive involvement and persistent course. Current therapeutic modalities often fail to achieve a successful response in patients with warts. We experienced a case involving an organ transplant recipient with recalcitrant mosaic warts who presented with complete clearance of lesions in 3 days after thermal spa bathing. Here, we evaluated the efficacy of natural thermal water versus hyperthermic tap water for treatment of recalcitrant hand warts in organ transplant recipients...

OBJECTIVES: Despite surgical advances and effective prophylactic strategies in liver transplant, infection is still a major cause of morbidity and mortality. Up to 80% of liver recipients will develop at least 1 infection during the first year after liver transplant. The spectrum and manifestations of these infections are broad and variable. Their diagnosis and treatment are often delayed because immunosuppressive therapy diminishes inflammatory responses. However, if an infection is not identified early enough and treated properly, it can have devastating consequences...

OBJECTIVES: In kidney transplant recipients, reduced muscle mass and hand-grip strength are associated with impaired nutritional status. Serum testosterone is highly associated with muscle strength in the general population. Here, we aimed to determine the associations among serum testosterone, hand-grip strength, and nutritional and inflammatory parameters, as well as graft function. MATERIALS AND METHODS: Our study included 144 stable male kidney transplant recipients from our renal transplant outpatient clinic...

Progress in patient care and immunosuppressive medications has resulted in improved allograft survival in the early posttransplant period; however, substantial graft loss continues in the long term. Therefore, the number of dialysis patients with failed allografts is increasing progressively. These patients have a worse prognosis than naive dialysis patients. Cardiovascular causes are the leading cause of death, followed by infections and malignancies. Delay in return to dialysis, a chronic inflammatory state, infections, and cancer are contributing factors to mortality, whereas type of dialysis modality does not have a significant effect on outcomes...

The literature has supported the concept of mesenchymal stromal cells (MSCs) in bone regeneration as one of the most important applications in oro-maxillofacial reconstructions. However, the fate of the transplanted cells and their effects on the clinical outcome is still uncertain. Photobiomodulation (PBM) plays an important role in the acceleration of tissue regeneration and potential repair. The aim of this in vitro study is to evaluate the effectiveness of PBM with 808 nm diode laser therapy, using a flat-top hand-piece delivery system at a higher-fluence (64 J/cm2 ) irradiation (1 W, continuous-wave) on bone marrow stromal cells (BMSCs)...

Huntington disease (HD) is an inherited disorder hallmarked by progressive deterioration of specific neurons, followed by movement and cognitive anomalies. Cell therapy approaches in neurodegenerative conditions have concentrated on the replenishment of lost/dying neurons with functional ones. Multipotent mesenchymal stem cells (MSCs) have been represented as a potential remedy for HD. In this study, we evaluated the in vitro and in vivo efficacy of umbilical cord matrix stem cells (UCMSCs) and their paracrine effect against oxidative stress with a specific focus on HD...

Skin infections caused by Paecilomyces species have been rarely described in patients with solid organ transplantation. Cutaneous manifestations are highly variable and include erythematous macules, nodules, pustules, and vesicular and necrotic lesions. The diagnosis of these infections is generally made by examination of a skin biopsy. Management of these fungal infections is difficult due to the immunocompromised state of the patients. Moreover, antifungal therapy and immunosuppressive drug interactions should be considered during treatment management...

A 61-year-old Caucasian man presented with papules on his left forearm and hand three months after liver transplantation: images from physical exam, pathology and microbiology are presented. Skin biopsy confirmed the presence of fungal elements within the hair shaft, which is consistent with Majocchi granuloma, also known as nodular granulomatous perifolliculitis. A combination of fungal culture, microscopic morphology, and gene sequencing was used to identify the causative organism. The patient recovered with appropriate systemic antifungal therapy...

BACKGROUND: Current guidelines recommend metronidazole for the treatment of mild-to-moderate C. difficile associated diarrhea (CDAD), while oral vancomycin is preferred for severe disease. However, data are lacking among the solid organ transplant (SOT) population. METHODS: This single center, retrospective cohort study evaluated adult SOT recipients with mild-to-moderate CDAD. Analysis 1 evaluated patients receiving initial therapy with metronidazole versus oral vancomycin for at least 72 hours...

Prior to cryopreservation, a tooth is transported from a contaminated oral environment to the tooth bank. Our objective was to identify all studies reporting or investigating a transport protocol prior to the cryopreservation of teeth, in terms of decontamination of the subjects. The systematic literature search (1970-2017) was based on MEDLINE via PubMed, Web of Science and the Cochrane Library. The reference lists of the included studies and the Science Citation Index were used for hand searching (snowballing)...

BACKGROUND: Vascularized composite allograft (VCA), such as hand and face allograft, contains a vascularized bone component that may provide an immunologic benefit and induce tolerance for the simultaneous inclusion of marrow cells and a marrow microenvironment. We developed a chimeric groin cutaneous/femur flap to investigate the effect of vascularized bone marrow on VCA survival and its ability to induce chimerism. METHODS: Brown Norway and Lewis rats were used as donors and recipients, respectively...

Background/Aims: Although the association between intrapulmonary shunt (IPS) and liver cirrhosis is clear, data of repeated contrast echocardiography (CE) before and after liver transplantation (LT) to evaluate factors associated with IPS are limited. Methods: Hand-agitated saline was used for CE and, by assessing left-chamber opacification, IPS was classified as grade 0 to 4. Grade 3/4 constituted significant IPS and hepatopulmonary syndrome (HPS) was defined as significant IPS with the arterial partial pressure of oxygen < 70 mmHg...

The number of elderly people has increased considerably over the last decades, due to a rising life expectancy and ageing populations. As a result, an increased number of elderly with end-stage-renal-disease are diagnosed, for which the preferred treatment is renal transplantation. Over the past years the awareness of the elderly as a specific patient population has grown, which increases the importance of research in this group. Elderly patients often receive kidneys from elderly donors while younger donor kidneys are preferentially reserved for younger recipients...

BACKGROUND AIMS: For patients needing allogeneic stem cell transplantation but lacking a major histocompatibility complex (MHC)-matched donor, haplo-identical (family) donors may be an alternative. Stringent T-cell depletion required in these cases to avoid lethal graft-versus-host disease (GVHD) can delay immune reconstitution, thus impairing defense against virus reactivation and attenuating graft-versus-leukemia (GVL) activity. Several groups reported that GVHD is caused by cells residing within the naive (CD45RA+ ) T-cell compartment and proposed use of CD45RA-depleted donor lymphocyte infusion (DLI) to accelerate immune reconstitution...

Liver transplant recipients are considered to be at high risk for Clostridium difficile infection, with an incidence of 2.7-8.0%, which is three times higher than that among other patients. A case of a patient who suffered from pseudomembranous colitis five times after living donor liver transplantation is reported. A 60-year-old woman underwent splenectomy and living donor liver transplantation using the left lobe of her spouse for primary biliary cirrhosis. The patient made a satisfactory recovery, except for splenic vein thrombosis...
