Novel Immunotherapy Targets for Relapsed/Refractory B-ALL: A Literature Review.

B-cell acute lymphoblastic leukemia (B-ALL) is the most prevalent cancer in United States children. In recent years, immunotherapies using chimeric antigen receptors (CAR T-cells) have improved prognosis for patients with B-ALL. Previous CAR T therapies have used CD19 as a target, but loss of this protein through antigen escape may cause relapse with slim chance of remission.

Short impact on soil microbiome of a QST713 based product that correlates with higher potato yield across USA.

Potato () is considered one of the most widely consumed crops worldwide, due to its high yield and nutritional profile, climate change-related environmental threats and increasing food demand. This scenario highlights the need of sustainable agricultural practices to enhance potato productivity, while preserving and maintaining soil health. Plant growth-promoting bacteria (PGPB) stimulate crop production through biofertilization mechanisms with low environmental impact.

Herbarium specimens reveal that mycorrhizal type does not mediate declining temperate tree nitrogen status over a century of environmental change.

Rising atmospheric carbon dioxide concentrations (CO) and atmospheric nitrogen (N) deposition have contrasting effects on ectomycorrhizal (EM) and arbuscular mycorrhizal (AM) symbioses, potentially mediating forest responses to environmental change. In this study, we evaluated the cumulative effects of historical environmental change on N concentrations and δN values in AM plants, EM plants, EM fungi, and saprotrophic fungi using herbarium specimens collected in Minnesota, USA from 1871 to 2016. To better understand mycorrhizal mediation of foliar δN, we also analyzed a subset of previously published foliar δN values from across the United States to parse the effects of N deposition and CO rise.

Precise surface functionalization of PLGA particles for human T cell modulation.

The biofunctionalization of synthetic materials has extensive utility for biomedical applications, but approaches to bioconjugation typically show insufficient efficiency and controllability. We recently developed an approach by building synthetic DNA scaffolds on biomaterial surfaces that enables the precise control of cargo density and ratio, thus improving the assembly and organization of functional cargos. We used this approach to show that the modulation and phenotypic adaptation of immune cells can be regulated using our precisely functionalized biomaterials.

The Subtlety of 22q11.2 Deletion Syndrome in a Preterm Neonate.

To date, 22q11.2 deletion syndrome (DS) is regarded as the most commonly diagnosed DS in humans. The location of the deletion on chromosome 22 affects the phenotypic presentation, which ranges from subtle to severe.

Preoperative Simulation of Retropubic Midurethral Sling to Decrease Bladder Perforation Rate Among Obstetrics and Gynecology Residents.

Importance: Bladder perforation is an often avoidable complication of retropubic midurethral sling procedures. Bladder injury rates decrease with surgeon experience, but literature on techniques to train novice surgeons is limited.

Objective: Our objective was to decrease the bladder perforation rate among obstetrics and gynecology residents during retropubic midurethral sling procedures through implementation of an instructional video and low-fidelity simulation.

Effectiveness and safety of direct oral anticoagulants in patients with venous thromboembolism and creatinine clearance < 30 mL/min.

The few studies that compared direct oral anticoagulants (DOAC) vs. warfarin in the setting of advanced renal insufficiency have focused on patients with atrial fibrillation. The purpose of this observational, matched, cohort study of patients was to assess the effectiveness and safety of DOAC vs.

Cerebral Venous Sinus Thrombosis Following COVID-19 and Otogenic Infection: A Diagnostic and Therapeutic Dilemma Followed by mRNA COVID-19 Vaccination.

IntroductionCerebral venous sinus thrombosis (CVST) is a rare neurovascular emergency that has been observed following COVID-19 infection, as well as following the use of non-mRNA COVID-19 vaccines. Case PresentationThe authors report a case of CVST in a 67-year-old woman, unvaccinated for COVID-19, who presented with acute otitis externa. It remains unclear whether the CVST was a following COVID-19 infection complication, otogenic CVST, or a combination of both.

Vibrio tetraodonis subsp. pristinus subsp. nov., isolated from the coral Acropora cytherea at Palmyra Atoll, and creation and emended description of Vibrio tetraodonis subsp. tetraodonis subsp. nov.

Strain OCN044 was isolated from the homogenised tissue and mucus of an apparently healthy Acropora cytherea coral fragment collected from the western reef terrace of Palmyra Atoll in the Northern Line Islands and was taxonomically evaluated with a polyphasic approach. The morphological and chemotaxonomic properties are consistent with characteristics of the genus Vibrio: Gram-stain-negative rods, oxidase- and catalase-positive, and motile by means of a polar flagellum. Strain OCN044 can be differentiated as a novel subspecies based on 21 differences among chemotaxonomic features (e.

Genetic modification of flavone biosynthesis in rice enhances biofilm formation of soil diazotrophic bacteria and biological nitrogen fixation.

Improving biological nitrogen fixation (BNF) in cereal crops is a long-sought objective; however, no successful modification of cereal crops showing increased BNF has been reported. Here, we described a novel approach in which rice plants were modified to increase the production of compounds that stimulated biofilm formation in soil diazotrophic bacteria, promoted bacterial colonization of plant tissues and improved BNF with increased grain yield at limiting soil nitrogen contents. We first used a chemical screening to identify plant-produced compounds that induced biofilm formation in nitrogen-fixing bacteria and demonstrated that apigenin and other flavones induced BNF.

Torsional Profiles of Thiophene and Furan Oligomers: Probing the Effects of Heterogeneity and Chain Length.

A systematic analysis of the torsional profiles of 55 unique oligomers composed of two to four thiophene and/or furan rings ( = 2 to 4) has been conducted using three density functional theory (DFT) methods along with MP2 and three different coupled-cluster methods. Two planar or quasi-planar minima were identified for each = 2 oligomer system. In every case, the torsional angle (τ) between the heteroatoms about the carbon-carbon bond connecting the two rings is at or near 180° for the global minimum and 0° for the local minimum, referred to as and conformations, respectively.

Do transgender men have equal access to health care and engagement in preventive health behaviors compared to cisgender adults?

Using 2015 Behavioral Risk Factor Surveillance System data, this study investigates whether transgender men have equal access to health care and engagement in preventive health behaviors compared to cisgender adults in the U.S. and whether race/ethnicity, socioeconomic status, and rural residence moderate these relationships.

Resource availability underlies the plant-fungal diversity relationship in a grassland ecosystem.

It is commonly assumed that microbial communities are structured by "bottom-up" ecological forces, although few experimental manipulations have rigorously tested the mechanisms by which resources structure soil communities. We investigated how plant substrate availability might structure fungal communities and belowground processes along an experimental plant richness gradient in a grassland ecosystem. We hypothesized that variation in total plant-derived substrate inputs, plant functional group diversity, as well as the relative abundance of C grasses and legumes would modulate fungal α- and β-diversity and their rates of soil carbon (C) and nitrogen (N) cycling.

High-sucrose-induced maternal obesity disrupts ovarian function and decreases fertility in Drosophila melanogaster.

As the obesity epidemic worsens, the prevalence of maternal obesity is expected to rise. Both high-fat and high-sucrose diets are known to promote maternal obesity and several studies have elucidated the molecular influence of high-fat feeding on female reproduction. However, to date, the molecular impact of a high-sucrose diet on maternal obesity remains to be investigated.

Soil microbial communities and elk foraging intensity: implications for soil biogeochemical cycling in the sagebrush steppe.

Foraging intensity of large herbivores may exert an indirect top-down ecological force on soil microbial communities via changes in plant litter inputs. We investigated the responses of the soil microbial community to elk (Cervus elaphus) winter range occupancy across a long-term foraging exclusion experiment in the sagebrush steppe of the North American Rocky Mountains, combining phylogenetic analysis of fungi and bacteria with shotgun metagenomics and extracellular enzyme assays. Winter foraging intensity was associated with reduced bacterial richness and increasingly distinct bacterial communities.

Exploring the complexities of body image experiences in middle age and older adult women within an exercise context: The simultaneous existence of negative and positive body images.

Despite many body changes that accompany the aging process, the extant research is limited on middle age and older adults' body image experiences. The purpose of the present study was to explore how body image is represented for middle age and older adult women. Using thematic analysis, 10 women over the age of 55 were interviewed within an exercise context.

Anthropogenic N Deposition Slows Decay by Favoring Bacterial Metabolism: Insights from Metagenomic Analyses.

Litter decomposition is an enzymatically-complex process that is mediated by a diverse assemblage of saprophytic microorganisms. It is a globally important biogeochemical process that can be suppressed by anthropogenic N deposition. In a northern hardwood forest ecosystem located in Michigan, USA, 20 years of experimentally increased atmospheric N deposition has reduced forest floor decay and increased soil C storage.

Soil microbial communities are shaped by plant-driven changes in resource availability during secondary succession.

Although we understand the ecological processes eliciting changes in plant community composition during secondary succession, we do not understand whether co-occurring changes in plant detritus shape saprotrophic microbial communities in soil. In this study, we investigated soil microbial composition and function across an old-field chronosequence ranging from 16 to 86 years following agricultural abandonment, as well as three forests representing potential late-successional ecosystems. Fungal and bacterial community composition was quantified from ribosomal DNA, and insight into the functional potential of the microbial community to decay plant litter was gained from shotgun metagenomics and extracellular enzyme assays.

Elk, sagebrush, and saprotrophs: indirect top-down control on microbial community composition and function.

Saprotrophic microbial communities in soil are primarily structured by the availability of growth-limiting resources (i.e., plant detritus), a bottom-up ecological force.

"If You Don't Have Anything Nice to Say, Then Don't Say Anything At All": Positive Appearance-Related Commentary and Physical Activity.

Background: Despite the well-documented benefits of physical activity, North Americans remain insufficiently inactive. Consequently, determining what motivates individuals to engage in physical activity becomes increasingly important. The purpose of this study was to examine whether the frequency of negative appearance-related commentary and positive appearance-related commentary could predict physical activity behavior.
