Microbe-induced drought tolerance by ABA-mediated root architecture and epigenetic reprogramming.

The use of beneficial microbes to mitigate drought stress tolerance of plants is of great potential albeit little understood. We show here that a root endophytic desert bacterium, Pseudomonas argentinensis strain SA190, enhances drought stress tolerance in Arabidopsis. Transcriptome and genetic analysis demonstrate that SA190-induced root morphogenesis and gene expression is mediated via the plant abscisic acid (ABA) pathway.

Nucleic acid nanotechnology provides the ability to create unprecedented nanostructures with diverse architectures and functions that can be utilized in myriad fields. A set of self-folding, single-stranded RNA origami structures bearing thrombin RNA aptamers have been demonstrated to act as anticoagulants. Here, we describe the detailed methods of producing and testing of such RNA origami anticoagulants.

Single-Center Experience Using the Cardiohelp System for Neonatal and Pediatric Extracorporeal Membrane Oxygenation.

Objectives: Extracorporeal membrane oxygenation (ECMO) systems have continued to evolve and improve with the development of smaller and portable systems. The Cardiohelp (Maquet Getinge Cardiopulmonary AG, Rastatt, Germany) portable life support device is a compact ECMO system used widely in adults and for ECMO transport. Reports of its use in neonatal and pediatric centers remain limited.

Large-scale placenta DNA methylation integrated analysis reveals fetal sex-specific differentially methylated CpG sites and regions.

Although male-female differences in placental structure and function have been observed, little is understood about their molecular underpinnings. Here, we present a mega-analysis of 14 publicly available placenta DNA methylation (DNAm) microarray datasets to identify individual CpGs and regions associated with fetal sex. In the discovery dataset of placentas from full term pregnancies (N = 532 samples), 5212 CpGs met genome-wide significance (p < 1E-8) and were enriched in pathways such as keratinization (FDR p-value = 7.

Loline Alkaloid Effects on Gastrointestinal Nematodes.

Loline, an alkaloid with several derivatives, has suggested antimicrobial and anthelmintic properties. Therefore, loline was investigated as a natural anthelmintic against , , and . Preliminary in vitro studies had reduced L3 establishment but no effect on L3 larvae migration or establishment.

Bioinstructive implantable scaffolds for rapid in vivo manufacture and release of CAR-T cells.

Despite their clinical success, chimeric antigen receptor (CAR)-T cell therapies for B cell malignancies are limited by lengthy, costly and labor-intensive ex vivo manufacturing procedures that might lead to cell products with heterogeneous composition. Here we describe an implantable Multifunctional Alginate Scaffold for T Cell Engineering and Release (MASTER) that streamlines in vivo CAR-T cell manufacturing and reduces processing time to a single day. When seeded with human peripheral blood mononuclear cells and CD19-encoding retroviral particles, MASTER provides the appropriate interface for viral vector-mediated gene transfer and, after subcutaneous implantation, mediates the release of functional CAR-T cells in mice.

The Lys-motif receptor LYK4 mediates Enterobacter sp. SA187 triggered salt tolerance in Arabidopsis thaliana.

Root endophytes establish beneficial interactions with plants, improving holobiont resilience and fitness, but how plant immunity accommodates beneficial microbes is poorly understood. The multi-stress tolerance-inducing endophyte Enterobacter sp. SA187 triggers a canonical immune response in Arabidopsis only at high bacterial dosage (>10  CFUs ml ), suggesting that SA187 is able to evade or suppress the plant defence system at lower titres.

Enhancement of heavy ion track-etching in polyimide membranes with organic solvents.

The effect of organic solvents on the ion track-etching of polyimide (PI) membranes is studied to enhance the nanopore fabrication process and the control over pore diameter growth. To this end, two approaches are employed to investigate the influence of organic solvents on the nanopore fabrication in PI membranes. In the first approach, the heavy ion irradiated PI samples are pretreated with organic solvents and then chemically etched with sodium hypochlorite (NaOCl) solution, resulting up to ∼4.

Multivalent Aptamer-Functionalized Single-Strand RNA Origami as Effective, Target-Specific Anticoagulants with Corresponding Reversal Agents.

Anticoagulants are commonly utilized during surgeries and to treat thrombotic diseases like stroke and deep vein thrombosis. However, conventional anticoagulants have serious side-effects, narrow therapeutic windows, and lack safe reversal agents (antidotes). Here, an alternative RNA origami displaying RNA aptamers as target-specific anticoagulant is described.

Rumen function and grazing behavior of early-lactation dairy cows supplemented with fodder beet.

Fodder beet (FB) is a source of readily fermentable carbohydrate that can mitigate early spring herbage deficits and correct the negative energy balance experienced during early lactation in pastoral dairy systems of New Zealand. However, the low-fiber and high-soluble carbohydrate content of both FB bulb and spring herbage are factors that promote subacute ruminal acidosis, impairing rumen function and limiting the marginal milk production response to supplement. In a crossover experiment, 8 Holstein Friesian × Jersey early-lactation dairy cows were used to test the effect of supplementing 16 kg of dry matter (DM) of a grazed perennial ryegrass herbage with 6 kg of DM/d of FB bulb (FBH) versus herbage only (HO) on changes in rumen function and grazing behavior.

Feeding an amino acid-formulated milk replacer for Holstein calves during 2 time periods.

The milk-fed calf has a requirement for essential amino acids (EAA) instead of crude protein (CP). However, most milk replacers (MR) are still formulated to a CP concentration, and although limited amounts of Lys or Met may be added, these MR are not formulated solely on an AA basis. Previous work has demonstrated that feeding a modified MR balanced for specific EAA concentrations of a 24% CP MR, but reducing CP to 22%, resulted in improved growth performance in calves compared with a 24% CP MR.

Supplementation of Spring Pasture with Harvested Fodder Beet Bulb Alters Rumen Fermentation and Increases Risk of Subacute Ruminal Acidosis during Early Lactation.

In a cross-over design, eight rumen cannulated dairy cows were used to explore the industry-recommended method for dietary transition to fodder beet (FB: L.) on changes to rumen fermentation and pH, milk production, dry matter intake (DMI) and the risk of subacute ruminal acidosis (SARA) during early lactation. Cows were split into two groups and individually allocated a ryegrass ( L.

Evaluation of essential oils and a prebiotic for newborn dairy calves.

A blend of essential oils (EO) and a prebiotic were combined (EOC) to formulate a colostrum-based liquid birth supplement and a separate feeding supplement (Start Strong and Stay Strong, Ralco Inc., Marshall, MN). These products were designed to promote immunity and stimulate appetite to diminish health challenges and stresses experienced by newborn calves.

A comparison of methods for estimating forage intake, digestibility, and fecal output in red deer (Cervus elaphus).

The objective of this experiment was to determine appropriate methods for estimating fecal output, digestibility, and intake in red deer (Cervus elaphus). Dry matter intake (DMI), digestibility, and fecal output were estimated using the dual-marker (titanium dioxide; TiO2 and indigestible acid detergent fiber) technique, double n-alkane ratio technique (ALK) and the pulse dose (Yttrium; Y) technique to determine a suitable method to estimate DMI, fecal output, and digestibility measurements. Four male and four female deer were stratified by sex and randomly assigned either fresh-cut perennial ryegrass (Lolium perenne L.

Variation of membrane particle-bound CD133 in cerebrospinal fluid of patients with subarachnoid and intracerebral hemorrhage.

Objective: Previous studies have demonstrated that human CSF contains membrane particles carrying the stem cell antigenic marker CD133 (prominin-1). Here, the authors analyzed the variation of the amount of these CD133-positive particles in the CSF of patients with subarachnoid hemorrhage (SAH) and intracerebral hemorrhage (ICH).

Methods: Consecutive CSF samples from 47 patients with SAH or ICH were compared to 14 healthy control patients.

Breast cancer, placenta and pregnancy.

Background: Breast cancer is one of the most frequently diagnosed malignancies during pregnancy. Tumours often present characteristics of high malignancy and are hormone receptor negative/HER2 positive or triple negative. In general, pregnancy, including the postpartum period, is associated with a transiently increased risk of developing breast cancer but followed by a long-lasting protective period.

Feeding Essential Oils to Neonatal Holstein Dairy Calves Results in Increased Ruminal Prevotellaceae Abundance and Propionate Concentrations.

Since antibiotic use in animal production has become a public health concern, great efforts are being dedicated to find effective and viable alternatives. While essential oils (EO) have become attractive candidates for use in the livestock industry, their mode of action and microbial targets in food animals remain largely uncharacterized. To gain further insight, we investigated the rumen environment of neonatal calves fed calf starter pellets and milk replacer supplemented with a commercial blend of EO.

Genetically Encoded, Functional Single-Strand RNA Origami: Anticoagulant.

Nucleic acid aptamers selected for thrombin binding have been previously shown to possess anticoagulant activity; however, problems with rapid renal clearance and short circulation half-life have prevented translation to clinical usefulness. Here, a family of self-folding, functional RNA origami molecules bearing multiple thrombin-binding RNA aptamers and showing significantly improved anticoagulant activity is described. These constructs may overcome earlier problems preventing clinical use of nucleic acid anticoagulants.

A Quality Improvement Project to Improve Sepsis-Related Outcomes at an Integrated Healthcare System.

Hospitals are encouraged to take steps to improve outcomes for patients with sepsis, a leading cause of morbidity and mortality. A retrospective analysis examined data (n = 4,475) from three health systems to better determine the impact of a 10-month sepsis quality improvement program that consisted of clinical alerts, audit and feedback, and staff education. Compared with the control group, the intervention group significantly decreased length of stay and costs per stay.

Breast carcinoma in pregnancy with spheroid-like placental metastases-a case report.

Breast cancer is one of the most common malignancies diagnosed in pregnancy. Although the tumor is often detected at an advanced stage, placental metastases are rare. Here, we describe the case of a woman with breast cancer recurrence during pregnancy and subsequent metastases.
