Utilization of initial chemotherapy for newly diagnosed acute myeloid leukemia in the United States.
Abstract The use of chemotherapy in patients with acute myeloid leukemia (AML) is associated with survival benefits and alleviation of symptoms related to AML. Prior studies have demonstrated a lower receipt of chemotherapy with increasing age and comorbidities. We hypothesized that socioeconomic and health system factors also determine the use of chemotherapy. We included 61 775 adults with AML diagnosed between 2003 and 2011 from the National Cancer Database, and performed a multivariable logistic regression model to determine the association between receipt of chemotherapy and several factors.

Safety and immunogenicity of conjugate quadrivalent meningococcal vaccination after hematopoietic cell transplantation.
Abstract Immunization with the conjugated quadrivalent (serogroups A, C, Y, and W-135) meningococcal vaccine (MCV4) after hematopoietic cell transplantation (HCT) is recommended. However, immune responses to MCV4 have not been prospectively studied after HCT. We conducted a vaccine response study among 67 adults who received 1 MCV4 dose a year after autologous or allogeneic HCT from January to September 2014. Pre- and postvaccination serogroup serum bactericidal antibody (SBA) titers were measured a median of 57 days after vaccination. Serogroup-specific responses were defined as a fourfold increase in SBA titer w...

In vivo RNAi screening identifies Pafah1b3 as a target for combination therapy with TKIs in BCR-ABL1+ BCP-ALL.
Abstract Despite the addition of tyrosine kinase inhibitors (TKIs) to the treatment of patients with BCR-ABL1+ B-cell precursor acute lymphoblastic leukemia (BCR-ABL1+ BCP-ALL), relapse both with and without BCR-ABL1 mutations is a persistent clinical problem. To identify BCR-ABL1-independent genetic mediators of response to the TKI dasatinib, we performed in vivo and in vitro RNA interference (RNAi) screens in a transplantable syngeneic mouse model of BCR-ABL1+ BCP-ALL. By using a novel combination of a longitudinal screen design and independent component analysis of screening data, we identified hairpins that ha...

Similar telomere attrition rates in androgen-treated and untreated patients with dyskeratosis congenita.
Abstract Dyskeratosis congenita (DC) is an inherited bone marrow failure syndrome and the prototypic telomere biology disorder (TBD). Leukocyte telomere length (TL) less than the first percentile for age, measured by flow cytometry with in situ hybridization (flow FISH), is diagnostic of DC. Androgens are a therapeutic option for DC/TBD-associated bone marrow failure (BMF). One report has shown an apparent increase in TL in patients while on treatment with the attenuated androgen danazol. The aim of this study was to compare TL over time in 10 androgen-treated and 16 untreated patients with DC. All subjects were e...

The characteristics of vessel lining cells in normal spleens and their role in the pathobiology of myelofibrosis.
Abstract The CD34-CD8α+, sinusoid lining, littoral cells (LCs), and CD34+CD8α-, splenic vascular endothelial cells (SVECs) represent 2 distinct cellular types that line the vessels within normal spleens and those of patients with myelofibrosis (MF). To further understand the respective roles of LCs and SVECs, each was purified from normal and MF spleens, cultured, and characterized. Gene expression profiling indicated that LCs were a specialized type of SVEC. LCs possessed a distinct gene expression profile associated with cytoskeleton regulation, cellular interactions, endocytosis, and iron transport....

Analysis of the thrombotic and fibrinolytic activities of tumor cell-derived extracellular vesicles.
Abstract Exosomes and microvesicles (MVs) are small extracellular vesicles secreted by tumor cells and are suggested to contribute to the thrombotic events that commonly occur in patients with advanced malignancies. Paradoxically, these vesicles have been reported to also possess fibrinolytic activity. To determine whether thrombotic or fibrinolytic activity is a predominant characteristic of these extracellular vesicles, we prepared exosomes and MVs from 2 breast cancer cell lines (MDA-MB-231 and MCF7), a lung cancer cell line (A549), and a leukemia cell line (NB4) and assayed their thrombotic and fibrinolytic ac...

In-situ magnetization/heating electron holography to study the magnetic ordering in arrays of nickel metallic nanowires.
Abstract Magnetic nanostructures of different size, shape, and composition possess a great potential to improve current technologies like data storage and electromagnetic sensing. In thin ferromagnetic nanowires, their magnetization behavior is dominated by the competition between magnetocrystalline anisotropy (related to the crystalline structure) and shape anisotropy. In this way electron diffraction methods like precession electron diffraction (PED) can be used to link the magnetic behavior observed by Electron Holography (EH) with its crystallinity. Using off-axis electron holography under Lorentz conditions, ...

3D Printing of Materials with Tunable Failure via Bioinspired Mechanical Gradients.
Abstract Mechanical gradients are useful to reduce strain mismatches in heterogeneous materials and thus prevent premature failure of devices in a wide range of applications. While complex graded designs are a hallmark of biological materials, gradients in manmade materials are often limited to 1D profiles due to the lack of adequate fabrication tools. Here, a multimaterial 3D-printing platform is developed to fabricate elastomer gradients spanning three orders of magnitude in elastic modulus and used to investigate the role of various bioinspired gradient designs on the local and global mechanical behavior of syn...

Thioether-Polyglycidol as Multivalent and Multifunctional Coating System for Gold Nanoparticles.
Abstract Thiofunctional polymers are the established standard for the coating and biofunctionalization of gold nanoparticles (AuNPs). However, the nucleophilic and oxidative character of thiols provokes polymeric crosslinking and significantly limits the chemical possibilities to introduce biological functions. Thioethers represent a chemically more stable potential alternative to thiols that would offer easier functionalization, yet a few studies in the literature report inconclusive data regarding the efficacy of thioethers to stabilize AuNPs in comparison to thiols. A systematic comparison is presented of mono-...

Laparoscopic Versus Open Adrenalectomy for Localized/Locally Advanced Primary Adrenocortical Carcinoma (ENSAT I-III) in Adults: Is Margin-Free (R0) Resection the Key Surgical Factor that Dictates Outcome?-A Review of the Literature.
CONCLUSIONS: LA appears to be equivalent to open method for localized/locally advanced primary ACC (ENSAT I-III) in terms of R0 resection rate, overall recurrence, DFS, and OS, therefore suggesting that the extent of surgery with adequate tumor resection is the predominant endpoint, rather than the surgical approach itself. Multicenter randomized controlled trials with long follow-up time periods exploring the long-term oncological outcomes are required to determine the benefits of the laparoscopic over the open approach in adrenocortical carcinoma.

Improving the convergence rate of a hybrid input-output phasing algorithm by varying the reflection data weight.
Abstract In an iterative projection algorithm proposed for ab initio phasing, the error metrics typically exhibit little improvement until a sharp decrease takes place as the iteration converges to the correct high-resolution structure. Related to that is the small convergence probability for certain structures. As a remedy, a variable weighting scheme on the diffraction data is proposed. It focuses on phasing low- and medium-resolution data first. The weighting shifts to incorporate more high-resolution reflections when the iteration proceeds. It is found that the precipitous drop in error metrics is replaced by ...

Perspective: interesterified triglycerides, the recent increase in deaths from heart disease, and elevated blood viscosity.
Abstract The authors hypothesize that consumption of interesterified fats may be the cause of the continuous increase in cardiovascular deaths in the United States which began in 2011. Interesterification is a method of producing solid fats from vegetable oil and began to supplant partial hydrogenation for this purpose upon recognition of the danger of trans fats to cardiovascular health. Long, straight carbon chains, as are present in saturated and trans fatty acids, decrease the fluidity of the erythrocyte cell membrane, which decreases erythrocyte deformability and increases blood viscosity.

Abstract The pulvinar can be subdivided into well-delimitated regions based on chemoarchitectural, cytoarchitectural, myeloarchitectural, connectivity, and electrophysiological criteria. Subdivisions of the pulvinar based on its chemoarchitectural features are the most consistently preserved across species of New and Old World monkeys. It is reasonable to speculate that the occurrence and distribution of calcium-binding proteins in the pulvinar, such as calbindin and parvalbumin, have been preserved along evolution. Therefore, they have proven to be valuable tools capable of probing the basic pulvinar scaffold acr...

Fertilization 1: Sperm-Egg Interaction.
Abstract In birds in the reproductive season, an egg is ovulated without cumulus cells from the largest follicle with the highest hierarchy in the ovary. The outermost part of the ovulated eggs is the perivitelline layer, a glycoprotein matrix consisting of a few ZP-glycoproteins. The fertilization starts from sperm penetration of the perivitelline layer predominantly in the germinal disc region, followed by uptake of the sperm into the egg, and goes through by the fusion of sperm male pronucleus with the female pronucleus in the egg. A series of these fertilization steps occurs in the infundibulum of the oviduct ...

[Gender-specific manifestations of daily physical activity and sedentary behaviour in elderly people of Surgut].
Abstract Objective of the study was to establish gender-specific characteristics of physical activity (PA) and sedentary behavior in elderly people living in Yugra North. 295 residents of Surgut (102 men aged 62,9±5,3 years, 35%; 193 women aged 61,9±3,8 years, 65%) were subject to a IPAQ-RU questionnaire. The study revealed the gender-specific differences in body length and mass, body mass and body fat indices. It was detected that more energy is spent on the housework and physical activity in the country (moderate-intensity physical activity for women and high-intensity one for men). The study data ...

Alemtuzumab in the long-term treatment of relapsing-remitting multiple sclerosis: an update on the clinical trial evidence and data from the real world.
Abstract Alemtuzumab is a humanized monoclonal antibody approved for the treatment of relapsing-remitting multiple sclerosis (RRMS), given as two annual courses on five consecutive days at baseline and on three consecutive days 12 months later. Here we provide an update on the long-term efficacy and safety of alemtuzumab in RRMS, including real-world experience, and advances in our understanding of its mechanism of action. Recent data from the phase II/III extension study have demonstrated that alemtuzumab reduces relapse rates, disability worsening, and the rate of brain volume loss over the long term, with many ...

The Correlation Between Biofilm Production and Catheter-Related Bloodstream Infections Sustained by Candida. A Case Control Study.
Abstract Biofilm forming capacity of yeasts colonizing the intravenous devices is considered a key factor involved in the pathogenesis of Candida catheter-related bloodstream infections (CCRBSI). The biofilm production of strains of Candida spp. isolated both from the CVC and from the blood of patients with CCRBSI was compared to that of strains isolated from patients not having CCRBSI. Results, expressed in terms of Biofilm Index (BI), revealed that biofilm-producing strains were isolated in the CCRBSI group with a frequency significantly higher than in the non-CCRBSI group (χ(2) = 4.25, p = 0.03). The specie...

Nanodroplet-Containing Polymers for Efficient Low-Power Light Upconversion.
Abstract Sensitized triplet-triplet-annihilation-based photon upconversion (TTA-UC) permits the conversion of light into radiation of higher energy and involves a sequence of photophysical processes between two dyes. In contrast to other upconversion schemes, TTA-UC allows the frequency shifting of low-intensity light, which makes it particularly suitable for solar-energy harvesting technologies. High upconversion yields can be observed for low viscosity solutions of dyes; but, in solid materials, which are better suited for integration in devices, the process is usually less efficient. Here, it is shown that this...

Developmental Neurotoxicity of Lead.
Abstract Lead exposure is a major concern for the developing nervous system. Environmental exposures to lead, predominantly from contaminated water or lead paint chips, account for the majority of exposures to children. In utero and early life exposures to lead have been associated with lower IQ, antisocial and delinquent behaviors, and attention-deficit hyperactivity disorder. In this review, we will discuss sources of developmental lead exposure and mechanisms of lead neurotoxicity. We will highlight both human epidemiological studies showing associations between lead exposure and behavioral abnormalities as wel...

Uranium and the Central Nervous System: What Should We Learn from Recent New Tools and Findings?
Abstract Increasing industrial and military use of uranium has led to environmental pollution, which may result in uranium reaching the brain and causing cerebral dysfunction. A recent literature review has discussed data published over the last 10 years on uranium and its effects on brain function (Dinocourt C, Legrand M, Dublineau I, et al., Toxicology 337:58-71, 2015). New models of uranium exposure during neonatal brain development and the emergence of new technologies (omics and epigenetics) are of value in identifying new specific targets of uranium. Here we review the latest studies of neurogenesis, ep...
