We discuss the current challenges and future prospects of flow-based organoid models and 3D self-assembling scaffolds. The existing paradigm of 3D culture suffers from a lack of control over organoid size and shape; can be an obstacle for cell harvesting and extended cellular and molecular analysis; and does not provide access to the function of exocrine glands. Moreover, existing organ-on-chip models are mostly composed of 2D extracellular matrix (ECM)-coated elastomeric membranes that do not mimic real organ architectures. A new comprehensive 3D toolbox for cell biology has emerged to address some of these issues. Advances in microfabrication and cell-culturing approaches enable the engineering of sophisticated models that mimic organ 3D architectures and physiological conditions, while supporting flow-based drug screening and secretomics-based diagnosis.

Closed genomes of commercial inoculant rhizobia provide a blueprint for management of legume inoculation.

Unlabelled: Rhizobia are soil bacteria capable of establishing symbiosis within legume root nodules, where they reduce atmospheric N into ammonia and supply it to the plant for growth. Australian soils often lack rhizobia compatible with introduced agricultural legumes, so inoculation with exotic strains has become a common practice for over 50 years. While extensive research has assessed the N-fixing capabilities of these inoculants, their genomics, taxonomy, and core and accessory gene phylogeny are poorly characterized.

The main goal of this investigation is to find out how solute carrier family 27 member 3 (SLC27A3) is expressed in the lung tissue of mice with chronic obstructive pulmonary disease (COPD), and how it relates to lung function. A model of COPD was established by exposing organisms to cigarette smoke, followed by investigating the role of SLC27A3 in COPD through experiments conducted both in living organisms and in laboratory settings. Knockout mice lacking SLC27A3 were produced through siRNA transfection to investigate lung function and inflammatory response, using methods such as hematoxylin-eosin staining and enzyme-linked immunosorbent assay.

The low reduction potentials required for the reduction of dinitrogen (N) render metal-based nitrogen-fixation catalysts vulnerable to irreversible damage by dioxygen (O). Such O sensitivity represents a major conundrum for the enzyme nitrogenase, as a large fraction of nitrogen-fixing organisms are either obligate aerobes or closely associated with O-respiring organisms to support the high energy demand of catalytic N reduction. To counter O damage to nitrogenase, diazotrophs use O scavengers, exploit compartmentalization or maintain high respiration rates to minimize intracellular O concentrations.

Microplastics (MPs) are fragments with a diameter of less than 5 mm that have been directly manufactured or formed by the degradation of plastic waste. MPs are not only prone to bioaccumulation in the environment, but they also lead to the spread of micropollutants in the environment, thereby threatening human health ecological environment. The useful detection method of MPs and understanding their abundance, characteristics and toxicity are great essential for MPs removal and control.

The pace of research efforts has been extraordinarily accelerated across the globe to address the contamination issues caused by pesticides, and fertilizers, especially in the aquatic ecosystem. The sole aim of this study was to assess the effect of urea on Nile Tilapia (Oreochromis niloticus). For this purpose, the fish fingerlings were exposed to increasing concentrations of urea such as 0, 1, 2.
