Financial, Social, and Health Impacts from the COVID-19 Pandemic: Findings from the Healthy Chicago Survey.

Background: This study examines self-reported impacts of the COVID-19 pandemic among Chicago residents and disparities of these impacts across demographic characteristics. Six logistic regression models were developed to identify demographic and socioeconomic factors associated with each COVID-19 impact.

Method: The study used de-identified and weighted data from the 2020 Healthy Chicago Survey (HCS).

Pedobacter luteus sp. nov., isolated from soil.

Two strains of Gram-staining-negative, rod-shaped bacteria that were motile by gliding, N7d-4(T) and B4a-b5, were isolated during a study of culturable bacteria in soil cultivated with potatoes. These isolates grew at 15-37 °C and at pH 6.5-7.

Agrimonia eupatoria protects against chronic ethanol-induced liver injury in rats.

This study examined the hepatoprotective effects of Agrimonia eupatoria water extract (AE) against chronic ethanol-induced liver injury. Rats were fed a Lieber-DeCarli liquid diet for 8 weeks. Animals were treated orally with AE at 10, 30, 100, and 300 mg/kg/day.

Paenibacillus pectinilyticus sp. nov., isolated from the gut of Diestrammena apicalis.

During a search for exo-enzyme-producing bacteria in the gut of an insect, Diestrammena apicalis, a novel bacterium capable of degrading pectin was isolated. The isolate, designated strain RCB-08(T), comprised Gram-positive, endospore-forming, motile rods capable of growth at 15-30 degrees C and pH 6.0-8.

Paenibacillus pueri sp. nov., isolated from Pu'er tea.

Pu'er tea is a fermented drink made from the leaves of the tea plant, Camellia sinensis. Two novel bacteria, designated strains b09i-3(T) and b13i-1, were isolated during the process of fermentation of this tea. These isolates were Gram-positive, endospore-forming, motile rods that grew at 25-42 degrees C and pH 5.

A culture-based study of the bacterial communities within the guts of nine longicorn beetle species and their exo-enzyme producing properties for degrading xylan and pectin.

In this study, bacterial communities within the guts of several longicorn beetles were investigated by a culture-dependent method. A total of 142 bacterial strains were isolated from nine species of longicorn beetle, including adults and larvae. A comparison of their partial 16S rRNA gene sequences showed that most of the bacteria constituting the gut communities can typically be found in soil, plants and the intestines of animals, and approximately 10% were proposed as unreported.

The diversity of culturable organotrophic bacteria from local solar salterns.

We isolated and cultured bacteria inhabiting solar saltern ponds in Taean-Gun, Chungnam Province, Korea. All of the isolated 64 strains were found to be moderately halophilic bacteria, growing in a salt range of 2-20 %, with an optimal concentration of 5% salt. Bacterial diversity among the isolated halophiles was evaluated via RFLP analyses of PCR-amplified 16S rDNAs, followed by phylogenetic analysis of the partial 16S rDNA sequences.

Amplification of mitochondrial small subunit ribosomal DNA of polypores and its potential for phylogenetic analysis.

There has been a systematic need to seek adequate phylogenetic markers that can be applied in phylogenetic analyses of fungal taxa at various levels. The mitochondrial small subunit ribosomal DNA (mt SSU rDNA) is generally considered to be one of the molecules that are appropriate for phylogenetic analyses at a family level. In order to obtain universal primers for polypores of Hymenomycetes, mt SSU rRNA genes were cloned from Bjerkandera adusta, Ganoderma lucidum, Phlebiopsis gigantea, and Phellinus laevigatus and their sequences were determined.
