Efficiency and process development for microbial biomass production using oxic bioelectrosynthesis.

Autotrophic microbial electrosynthesis (MES) processes are mainly based on organisms that rely on carbon dioxide (CO) as an electron acceptor and typically have low biomass yields. However, there are few data on the process and efficiencies of oxic MES (OMES). In this study, we used the knallgas bacterium Kyrpidia spormannii to investigate biomass formation and energy efficiency of cathode-dependent growth.

Machine learning to extract muscle fascicle length changes from dynamic ultrasound images in real-time.

Background And Objective: Dynamic muscle fascicle length measurements through B-mode ultrasound have become popular for the non-invasive physiological insights they provide regarding musculoskeletal structure-function. However, current practices typically require time consuming post-processing to track muscle length changes from B-mode images. A real-time measurement tool would not only save processing time but would also help pave the way toward closed-loop applications based on feedback signals driven by in vivo muscle length change patterns.

How Comparable are Microbial Electrochemical Systems around the Globe? An Electrochemical and Microbiological Cross-Laboratory Study.

A cross-laboratory study on microbial fuel cells (MFC) which involved different institutions around the world is presented. The study aims to assess the development of autochthone microbial pools enriched from domestic wastewater, cultivated in identical single-chamber MFCs, operated in the same way, thereby approaching the idea of developing common standards for MFCs. The MFCs are inoculated with domestic wastewater in different geographic locations.

Monitoring stratification of anode biofilms in bioelectrochemical laminar flow reactors using flow cytometry.

A laminar flow bioelectrochemical systems (BES) was designed and benchmarked using microbial anodes dominated with spp. The reactor architecture was based on modeled flow fields, the resulting structure was 3D printed and used for BES manufacturing. Stratification of the substrate availability within the reactor channels led to heterogeneous biomass distribution, with the maximum biomass found mainly in the initial/middle channels.

CAPACITY OF EXERCISE AND SURVIVAL IN PATIENTS WITH CIRRHOSIS WITH AND WITHOUT HEPATOPULMONARY SYNDROME AFTER LIVER TRANSPLANTATION.

Methods: A prospective cohort study, consisting initially of 178 patients, of whom 90 underwent LT (42 with HPS and 48 without HPS).

Photosynthetic activity of rice sister lines with contrasting cold tolerance.

Incidence of cold during early stages is an obstacle for the growing progress of rice plants. Cold stress has strong negative effects on photosynthetic activity. Previously, our group evaluated plant survival of 90 rice genotypes after cold treatment.

Response-Surface-Optimized and Scaled-Up Microbial Electrosynthesis of Chiral Alcohols.

A variety of enzymes can be easily incorporated and overexpressed within Escherichia coli cells by plasmids, making it an ideal chassis for bioelectrosynthesis. It has recently been demonstrated that microbial electrosynthesis (MES) of chiral alcohols is possible by using genetically modified E. coli with plasmid-incorporated and overexpressed enzymes and methyl viologen as mediator for electron transfer.

Assessment of Anthropometric and Physical Health Indicators before and after Pituitary Surgery in Patients with Nonfunctioning Pituitary Adenomas, Acromegaly, and Cushing Disease.

Introduction: Individuals with pituitary adenomas may have organic consequences of their disease or therapy, and psychological changes can compromise their quality of life (QoL). This study aimed to determine the anthropometric profile and health indicators of patients with pituitary adenoma before and after pituitary surgery.

Genotype Variation in Rice ( L.) Tolerance to Fe Toxicity Might Be Linked to Root Cell Wall Lignification.

Iron (Fe) is an essential element to plants, but can be harmful if accumulated to toxic concentrations. Fe toxicity can be a major nutritional disorder in rice () when cultivated under waterlogged conditions, as a result of excessive Fe solubilization of in the soil. However, little is known about the basis of Fe toxicity and tolerance at both physiological and molecular level.

Crystal Structure of Dihydro-Heme d Dehydrogenase NirN from Pseudomonas aeruginosa Reveals Amino Acid Residues Essential for Catalysis.

Many bacteria can switch from oxygen to nitrogen oxides, such as nitrate or nitrite, as terminal electron acceptors in their respiratory chain. This process is called "denitrification" and enables biofilm formation of the opportunistic human pathogen Pseudomonas aeruginosa, making it more resilient to antibiotics and highly adaptable to different habitats. The reduction of nitrite to nitric oxide is a crucial step during denitrification.

Resting Escherichia coli as Chassis for Microbial Electrosynthesis: Production of Chiral Alcohols.

Chiral alcohols constitute important building blocks that can be produced enantioselectively by using nicotinamide adenine dinucleotide (phosphate) [NAD(P)H]-dependent oxidoreductases. For NAD(P)H regeneration, electricity delivers the cheapest reduction equivalents. Enzymatic electrosynthesis suffers from cofactor and enzyme instability, whereas microbial electrosynthesis (MES) exploits whole cells.

Reactors for Microbial Electrobiotechnology.

From the first electromicrobial experiment to a sophisticated microbial electrochemical process - it all takes place in a reactor. Whereas the reactor design and materials used strongly influence the obtained results, there are no common platforms for MES reactors. This is a critical convention gap, as cross-comparison and benchmarking among MES as well as MES vs.

Subgingival Irrigation with a Solution of 20% Propolis Extract as an Adjunct to Non-Surgical Periodontal Treatment: A Preliminary Study.

Natural products, including propolis, are now frequently used to treat periodontal disease, but there are a few clinical studies in this area. The aim of this randomized clinical trial was to evaluate the effect of subgingival irrigation of periodontal pockets with a hydroalcoholic solution of propolis extract 20% (w/v) as an adjunct to periodontal therapy. Sixteen individuals were divided into a test group (TG), comprised 65 teeth (scaling and root planing + irrigation with propolis solution), and a control group (CG), comprised 62 teeth (scaling and root planing + irrigation with saline solution).
