Risk Factors for Postoperative Urinary Tract Infections in Paediatric Hydronephrosis: A Retrospective Analysis.

Background: Paediatric hydronephrosis frequently necessitates surgical intervention. However, postoperative urinary tract infections (UTIs) are common and challenging. This retrospective cohort study aimed to identify UTI risk factors following an operation for paediatric hydronephrosis.

The centralspindlin complex regulates cytokinesis and morphogenesis in the C. elegans spermatheca.

Organ morphogenesis needs orchestration of a series of cellular events, including cell division, cell shape change, cell rearrangement and cell death. Cytokinesis, the final step of cell division, is involved in the control of organ size, shape and function. Mechanistically, it is unclear how the molecules involved in cytokinesis regulate organ size and shape.

Generation and characterization of cardiac valve endothelial-like cells from human pluripotent stem cells.

The cardiac valvular endothelial cells (VECs) are an ideal cell source that could be used for making the valve organoids. However, few studies have been focused on the derivation of this important cell type. Here we describe a two-step chemically defined xeno-free method for generating VEC-like cells from human pluripotent stem cells (hPSCs).

sp. nov., isolated from Antarctic tundra soil, and emended descriptions of , , and .

A rod-shaped, yellow-pigmented, Gram-stain-negative, non-motile and aerobic bacterium, designated 7-3A, was isolated from soil from King George Island, maritime Antarctica, and subjected to a polyphasic taxonomic study. Growth occurred at 4-37 °C (optimum, 20°C) and at pH 5.0-9.

sp. nov., isolated from Arctic tundra soil.

A Gram-stain-negative, rod-shaped, green-pigmented, aerobic and motile bacterium, strain R3-44, was isolated from Arctic tundra soil. Stain R3-44 clustered closely with members of the genus , which belongs to the family , and showed the highest 16S rRNA sequence similarity to AR2 (96.10%).

gen. nov., sp. nov., isolated from soil in Fildes Peninsula, Antarctica.

A novel strain, designated AQ6-296, was isolated from a soil sample collected in Fildes Peninsula, Antarctic. Cells were Gram-stain-negative, non-endospore-forming, non-motile, strictly aerobic and rod-shaped. Growth occurred at 4-28 °C (optimum, 20 °C) and at pH 6.

Correction to: Hymenobacter oligotrophus sp. nov., isolated from a contaminated agar plate.

In the original publication, the deposit number of strain sh-6 was incorrectly published as "CCTCC AB 2016064" throughout the article.

sp. nov., isolated from soil sampled at Fildes Peninsula, Antarctica.

Strain YZ-8, isolated from soil sampled at Fildes Peninsula, Antarctica, was found to be a Gram-stain-negative, yellow-pigmented, oxidase- and catalase-positive, non-motile, non-spore-forming, rod-shaped and aerobic bacterium. Strain YZ-8 grewoptimally at pH 7.0 and 20 °C.

sp. nov., isolated from soil on the South Shetland Islands, Antarctica.

A Gram-stain-negative, non-motile, strictly aerobic, coccus-shaped bacterium, designated S14-83, was isolated from a soil sample collected from the South Shetland Islands of Antarctica. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the strain is a novel member of the genus , with as its closest relative (96.1 % similarity).

Hymenobacter oligotrophus sp. nov., isolated from a contaminated agar plate.

A taxonomic study of a Gram-stain negative, rod-shaped, motile, asporogenous, catalase- and oxidase-positive bacterium, sh-6, forming pink-red colonies, isolated from a contaminated R2A plate in the laboratory was performed. Its optimum growth temperature was determined to be 28 °C in the absence of NaCl on R2A plates. On the basis of 16S rRNA gene sequence analysis, strain sh-6 belongs to the genus Hymenobacter and is closely related to Hymenobacter deserti ZLB-3 (95.
