From late nineteen nineties, the higher number of suitable renal transplant candidates has forced the transplant community to re-explore the whole spectrum of deceased donors after brain death (DBD) as well as after cardiac death (DCD); in practice, donors of older age and donors with more chronic diseases or "medical complexities". This new kidney donor population - finally defined as extended criteria donors (ECD) - currently comprises on average 20 to 25%. In his seminal paper in 2003 on the introduction of ECD in the US, Metzger et al...

Nuclear receptors (NRs) are a diverse class of transcription factors, which are involved in regulating a large number of physiological events in metazoans. However, the function of NRs is poorly understood in plant-parasitic nematodes. Here, members of the NR1J+K group of NRs in nematodes, including the free-living and plant parasites, were examined and phylogenetically analyzed. We found that the number of members of the NR1J+K group in plant-parasitic nematodes was less than that in the free-living nematodes, suggesting this reduction of NR1J+K group members in plant parasites maybe arose during the separation of the free-living and intermediately plant parasitic nematodes (Bursaphelenchus xylophilus)...

Available literature points to healthcare providers' discomfort with donation after cardiac death (DCD) and their perception of the public's reluctance toward the procedure. Using a national sample, we report on the communication content of actual DCD and donation after brain death (DBD) approaches by organ procurement organization (OPO) requesters and compare family decision makers' (FDMs') experiences of both modalities. We recruited 1,601 FDMs using a validated protocol; 347 (21.7%) were of potential DCD donors...

The paper reports the use of atmospheric non-thermal plasma torch as a catalyst for degradation of various organic pollutants dissolved in water. A flow of He mixed with air was used to produce the dielectric barrier discharge (DBD), at the tip of the torch, using pulsed electric excitation at 12 kV. The torch, operated at a power of 750 mW/mm(2), was seen to completely degrade the aqueous solutions of the pollutants namely methylene blue (MB), methyl orange (MO) and rhodamine-B (RB), at around 10(-4) M concentrations, the concentration of polluants is one order higher than of routinely used heterogeneous photocatalytic reactions, within 10 min of irradiation time at room temperature...

It is well known that the quality of organs retrieved from brain-dead donors (DBDs) is better than those retrieved from circulatory death donors. However, in situations of organ retrieval from marginal DBDs, who are unstable despite intensive care, transplantation outcomes are not good. Organ ischemia is the most important determining factor in decreased organ quality in circulatory death donors and in some DBDs. Extracorporeal membrane oxygenation (ECMO) for management of DBDs can be an emergency countermeasure...

An increasing number of elderly patients (≥65 years) receive a donor kidney from elderly donors after brain death (DBD) or after circulatory death (DCD). These organs are allocated within the Eurotransplant Senior Program, but outcomes must be evaluated. From the Dutch Organ Transplantation Registry, we selected 3597 recipients (≥18 years) who received a first DBD or DCD kidney during 2002-2012, and categorized them as young or elderly recipients receiving a graft from either a young or elderly donor, stratified by donor type...

Methods to visualize, track, measure, and perturb or activate proteins in living cells are central to biomedical efforts to characterize and understand the spatial and temporal underpinnings of life inside cells. Although fluorescent proteins have proven to be extremely useful for in vivo studies of protein function, their utility is inherently limited because their spectral and structural characteristics are interdependent. These limitations have spurred the creation of alternative approaches for the chemical labeling of proteins...

The atmospheric double barrier discharge (DBD) plasma technology is a promising tool in food industry as an alternative to traditional food preservation methods. However, the effect of the reactive chemical species generated during the treatment on the qualitative and quantitative content of bioactive compounds in food is still little studied, as well as there are no data concerning potential deleterious effects of DBD treated foods on human cells. We measured antioxidants content and antioxidant capacity of DBD-treated minimally processed Pink Lady® apples in comparison with untreated matched samples...

BACKGROUND: Adverse childhood experiences (ACEs) and psychiatric disorders are common in juvenile detainees. Emotional dysregulation resulting from cumulated ACEs may be characterized by symptoms of irritability. The present study examined whether the accumulation of ACEs, irritability, or both predicted mental disorders in incarcerated adolescents with and without controlling for one another and for socio-demographic factors. METHODS: One hundred thirty male detained juvenile offenders (aged 13...

The effect of plasma applied to mulungu (Erythrina velutina) seeds was studied to verify its influence on the germination, water absorption, wettability and structure of the seeds. The plasma jet used in this study was produced by dielectric barrier discharge (DBD) in a helium gas flow of 0.03 L/s at a distance of 13 mm for 60 s. The plasma treatment significantly affected the seed germination rate, which was approximately 5% higher than that of the untreated group. Micropyle and hilum contributed a greater proportion to uptake...

Maternally expressed gene 3 (MEG3) is suggested to function as a long non-coding RNA (lncRNA) and to play roles in various human cancers. However, the functional properties of MEG3 in ischemic stroke remain unknown. Here, we report that expression of MEG3 is upregulated following ischemia in adult mice. Moreover, cerebral ischemia recruits p53 into the MEG3 complex in ischemic tissues. MEG3 directly binds with the p53 DNA binding domain (DBD) consisting of amino acids 271-282 (p53-DBD(271)(-)(282)), which stimulates p53-mediated transactivation and mediates ischemic neuronal death...

Diabetic bladder dysfunction (DBD) is a common urological complication of diabetes. Innate immune system activation via Toll-like receptor 4 (TLR4) leads to inflammation and oxidative stress and was implicated in diabetes pathophysiology. We hypothesized that bladder hypertrophy and hypercontractility in DBD is mediated by TLR4 activation. Wild type (WT) and TLR4 knock-out (TLR4KO) mice were made diabetic by streptozotocin (STZ) treatment and bladder contractile function and TLR4 pathway expression were evaluated...

The PPAR-RXR complex is one of the most significant and prevalent regulatory systems, controlling lipid metabolism by gene expression. Both proteins are members of the nuclear hormone receptor family, consisting of a ligand-binding domain (LBD), a hinge and a DNA binding domain (DBD). The two proteins form a heterodimer in the nucleus. The ligand-free complex interacts with corepressor proteins and blocks the expression of the genes. With the activating ligands and coactivator segments of regulating proteins, the heterodimer becomes active and allows translation of the genes under its control...

Non-thermal plasma has been extensively researched as a new cancer treatment technology. We investigated the selective cytotoxic effects of non-thermal micro-dielectric barrier discharge (micro-DBD) plasma in cervical cancer cells. Two human cervical cancer cell lines (HeLa and SiHa) and one human fibroblast (HFB) cell line were treated with micro-DBD plasma. All cells underwent apoptotic death induced by plasma in a dose-dependent manner. The plasma showed selective inhibition of cell proliferation in cervical cancer cells compared to HFBs...

The p53 family of proteins is comprised of p53, p63 and p73. Because the p53 DNA binding domain (DBD) is naturally unstable and possesses an amyloidogenic sequence, it is prone to form amyloid fibrils, causing loss of functions. To develop p53 therapies, it is necessary to understand the molecular basis of p53 instability and aggregation. Light scattering, thioflavin T (ThT) and high hydrostatic pressure (HHP) assays showed that p53 DBD aggregates faster and to a greater extent than p63 and p73 DBDs, and was more susceptible to denaturation...

Transposable elements have played a critical role in the creation of new genes in all higher eukaryotes, including humans. Although the chimeric fusion protein SETMAR is no longer active as a transposase, it contains both the DNA-binding domain (DBD) and catalytic domain of the Hsmar1 transposase. The amino-acid sequence of the DBD has been virtually unchanged in 50 million years and, as a consequence, SETMAR retains its sequence-specific binding to the ancestral Hsmar1 terminal inverted repeat (TIR) sequence...

Glyphosate was one of the most widely used herbicides in the world. Remediation of glyphosate-contaminated soil was conducted using atmospheric pressure dielectric barrier discharge (DBD) plasma. The feasibility of glyphosate degradation in soil was explored, and the soil leachate toxicity after remediation was assessed via a seed germination test. The experimental results showed that approximately 93.9% of glyphosate was degraded within 45min of DBD plasma treatment with an energy yield of 0.47gkWh(-1), and the degradation process fitted the first-order kinetic model...
