The presence of noise usually impairs the processing of a stimulus. Here, we studied the effects of noise on face processing and show, for the first time, that adaptation to noise patterns has beneficial effects on face perception. We used noiseless faces that were either surrounded by random noise or presented on a uniform background as stimuli. In addition, the faces were either preceded by noise adaptors or not. Moreover, we varied the statistics of the noise so that its spectral slope either matched that of the faces or it was steeper or shallower...

BACKGROUND: Primary refractory acute myeloid leukemia (PRF-AML) is associated with a dismal prognosis. Allogeneic stem cell transplantation (HSCT) in active disease is an alternative therapeutic strategy. The increased availability of unrelated donors together with the significant reduction in transplant-related mortality in recent years have opened the possibility for transplantation to a larger number of patients with PRF-AML. Moreover, transplant from unrelated donors may be associated with stronger graft-mediated anti-leukemic effect in comparison to transplantations from HLA-matched sibling donor, which may be of importance in the setting of PRF-AML...

Stable colloidal silver nanoparticles (AgNPs) were synthesized using Caulerpa serrulata (green marine algae) aqueous extract as an efficient reducing and stabilizing agent. This method is considered to be a sustainable alternate to the more complicated chemical procedures. To achieve the optimization synthesis of AgNPs, several effects such as extract concentration, contact time, pH values, and temperature were examined. The synthesized AgNPs were characterized by UV-Vis spectroscopy, FT-IR, XRD, and HR-TEM...

Behavioural activation and physical activity have received empirical support that highlight their efficacy in reducing depression. Even though both behavioural activation and physical activity share the common goal of reactivating the individual, limited research has directly compared these interventions, and more research is required to evaluate their efficacy when offered in low-intensity formats. The present study involves a randomized controlled clinical trial comparing the efficacy of two guided self-help interventions for the treatment of depression: behavioural activation and physical activity...

This study investigated whether different breathing conditions during exercise testing will influence measures of exercise capacity commonly used for training prescription in chronic obstructive pulmonary disease. Twenty-seven patients with chronic obstructive pulmonary disease (forced expiratory volume in 1 sec = 45.6 [9.4]%) performed three maximal exercise tests within 8 days, but at least 48 hrs apart. Subjects were thereby breathing either room air through a tightly fitting face mask like during any cardiopulmonary exercise test (MASK), room air without mask (No-MASK), or 10 l/min of oxygen via nasal cannula (No-MASK + O2)...

Extracorporeal Membrane Oxygenation (ECMO) has become well established technique of the treatment of severe acute respiratory failure (Veno-Venous ECMO) or circulatory failure (Veno-Arterial ECMO) which enables effective blood oxygenation and carbon dioxide removal for several weeks. Veno-Venous ECMO (V-V ECMO ) is a lifesaving treatment of patients in whom severe ARDS makes artificial lung ventilation unlikely to provide satisfactory blood oxygenation for preventing further vital organs damage and progression to death...

BACKGROUND: Contemporary medicine does not concern the issue of dosimetry in photodynamic diagnosis (PDD) but follows the photosensitizer (PS) producers recommendation. Most preclinical and clinical PDD studies indicate a considerable variation in the possibility of visualization and treatment, as e.g. in case of cervix lesions. Although some of these variations can be caused by the different histological subtypes or various tumor geometries, the issue of varying PS concentration in the tumor tissue volume is definitely an important factor...

REVIEW
Daniel J Weisdorf
Allotransplantation cures patients by cytoreduction and the graft-versus-tumor (leukemia; graft-versus-leukemia [GVL]) alloresponse; both eliminate residual disease. The spectrum of conditioning intensity influences toxicities and non-relapse mortality. The spectrum of tumor sensitivity to the GVL response influences relapse. Balancing tolerable toxicities (influenced by patients' performance status and comorbidities) is also influenced by the graft. Intense immunosuppression (for engraftment and graft-versus-host disease prevention) may constrain the immunologic potency of the graft and limit the antineoplastic capacity of the transplant, thus requiring more intense or more effective conditioning regimens to limit the risks of relapse and permit satisfactory disease-free survival...

Allogeneic hematopoietic stem cell transplantation (HSCT) remains the only curative therapy for sickle cell disease (SCD); however, its use is limited by lack of suitable human leukocyte antigen (HLA)-matched donors and decreased application in older patients with significant morbidity. Myeloablative, HLA-identical sibling transplantation in children with SCD offers excellent long-term survival, with overall and event-free survival rates of 95% and 92%, respectively. However, the risk of graft-versus-host-disease, infections, infertility, and other long-term transplant complications, further limits its widespread use...

BACKGROUND: Although depression is a risk factor for cardiovascular disease (CVD), it is unknown whether this risk varies across depressive disorder subtypes. Thus, we investigated atypical major depressive disorder (MDD) and double depression as predictors of new-onset CVD in a nationally representative sample of U.S. adults. METHODS: Prospective data from 28,726 adults initially free of CVD who participated in Wave 1 (2001-2002) and Wave 2 (2004-2005) of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) were examined...

BACKGROUND: The feasibility of cord blood transplantation (CBT) in adults is limited by the relatively low number of hematopoietic stem/progenitor cells contained in one single CB unit. The infusion of two CB units from different partially HLA-matched donors (double CBT) is frequently performed in patients who lack a sufficiently rich single CB unit. METHODS: We compared CBT outcomes in patients given single or double CBT following reduced-intensity conditioning (RIC) in a retrospective multicenter registry-based study...

Bacteria possess molecular biosensors that enable responses to a variety of stressful conditions, including oxidative stress, toxic compounds, and interactions with other organisms, through elaborately coordinated regulation of gene expression. In Escherichia coli and related bacteria, the transcription factor SoxR functions as a sensor of oxidative stress and nitric oxide (NO). SoxR protein contains a [2Fe-2S] cluster essential for its transcription-enhancing activity, which is regulated by redox changes in the [2Fe-2S] cluster...

Obesity affects more than 35% of Americans, increasing the risk of more than 200 comorbid conditions, impaired quality of life and premature mortality. This review aimed to summarize literature published over the past 15 years regarding the prevalence and impact of obesity in people with haemophilia (PWH) and to discuss implementing general guidelines for weight management in the context of the haemophilia comprehensive care team. Although few studies have assessed the effects of obesity on haemophilia-specific outcomes, existing evidence indicates an important impact of weight status on lower extremity joint range of motion and functional disability, with potentially important effects on overall quality of life...

Non-Hodgkin's lymphoma (NHL) constitutes a collection of lymphoproliferative disorders with diverse biologic, histologic, and clinical features. With a better understanding of the molecular pathogenesis, recently there have been major advances in the treatment of NHLs including addition of novel monoclonal antibodies, targeted therapies, and immune activators to the therapy armamentarium. Despite these remarkable developments, autologous hematopoietic cell transplantation (auto-HCT) remains not only a standard-of-care curative option for aggressive NHL but also an important therapeutic option for indolent NHL...
