Minimally Invasive Technique for Direct Measurement of Neonatal Hemodynamic Utilizing the COstatus Monitor
Background:The objective of this study is to establish feasibility of directly measuring cardiac output in a neonatal population using the COstatusMonitor (Transonic Systems, Ithaca, NY USA).Methods:The COstatus Monitor utilizes an extracorporeal loop attached to arterial and venous lines to measure cardiac output using ultrasound dilution. Injections of 1mL/kg of body temperature saline were injected into the loop. Up to two measurement sessions were performed daily for a maximum of four days for each patient.Results:Cardiac output was measured 54 times in 12 neonates with no adverse events. Infants ranged in weight (0.72 to 3.74 kg), gestational age (24 to 41.3 weeks), and day of life (1 to 13 days). The mean cardiac output was 0.43 L/min with a mean cardiac index of 197 mL/kg/min.Conclusions:Direct measurement of cardiac output by the COstatus monitor is feasible in a neonatal population. Minimal variance was exhibited for all parameters in consecutive measurements.

Nano Materials and Soil Fertility
Nano materials play a significant role for protecting soil and sustaining arable lands through implementing the efficiency of fertilizers and pesticides, there are different benefits of Nano materials include managing soil fertility, reduce soiltoxicity, sustaining the environment, and reduce soil degradation under climate change conditions. The mechanism for nano materials depends on their small size with a large specific surface area, also, the slow release of nano fertilizers which increases the absorption efficiency of nutrients and other compounds for plant growth and metabolism, also, nano materials could use as nano-coatings for various nutrients to increase absorbed efficiency and permitted slow sustained release of nano-coating fertilizers.

Six must-haves for lovers of houseplants
Indoor plants can make any space feel brighter, fresher, and homier. Not only do plants quite literally clean your air, they also add some much-needed greenery to what some may describe as drab city apartments. These essentials are great for any type of plant parent, be that a horticulture newbie or the head of a large family of plant “children."This is one of the most exciting indoor plant terrariums on the market. If you’re looking to create a real showcase for your indoor plants, this is the way to go. This 16-gallon orb creates its own microenvironment with a natural LED light cycle and automatic misting to keep your plants happy 365 days a year. The beautiful thing about the biOrbAIR 60 is that you can have a lot of fun with unique plants that may not usually survive an indoor environment. It's also just a home good that will impress your friends.

Initial soil microbiome composition and functioning predetermine future plant health

Abstract
Plant-pathogen interactions are shaped by multiple environmental factors, making it difficult to predict disease dynamics even in relatively simple agricultural monocultures. Here, we explored how variation in the initial soil microbiome predicts future disease outcomes at the level of individual plants. We found that the composition and functioning of the initial soil microbiome predetermined whether the plants survived or succumbed to disease. Surviving plant microbiomes were associated with specific rare taxa, highly pathogen-suppressing Pseudomonas and Bacillus bacteria, and high abundance of genes encoding antimicrobial compounds. Microbiome-mediated plant protection could subsequently be transferred to the next plant generation via soil transplantation. Together, our results suggest that small initial variation in soil microbiome composition and functioning can determine the outcomes of plant-pathogen interactions under natural field conditions.
