The ADP-glucose pyrophosphorylase from Melainabacteria: A comparative study between photosynthetic and non-photosynthetic bacterial sources.

Biochimie 2021 Sep 21. Epub 2021 Sep 21.

Instituto de Agrobiotecnología del Litoral, Universidad Nacional del Litoral, Consejo Nacional de Investigaciones Científicas y Técnicas, Facultad de Bioquímica y Ciencias Biológicas, Santa Fe, Argentina. Electronic address:

Until recently, the cyanobacterial phylum only included oxygenic photosynthesizer members. The discovery of Melainabacteria as a group of supposed non-photosynthetic cyanobacteria asked to revisit such scenario. From metagenomic data, we were able to identify sequences encoding putative ADP-glucose pyrophosphorylases (ADP-GlcPPase) from free-living and intestinal Melainabacteria. Read More

Department of Orthopaedic Surgery, Nishinokyo Hospital, 102-2 Rokujyocho, Nara City, Nara 630-8041, Japan.

Objective: To investigate whether or not the fusion rate after posterior lumbar interbody fusion with cortical bone trajectory screw fixation (CBT-PLIF) is lower than after PLIF using traditional trajectory screw fixation (TT-PLIF) and whether or not the titanium-coated polyetheretherketone (PEEK) cage (TiP cage) improves fusion status compared to the same shape uncoated PEEK cage (P cage).

Methods: The subjects were 37 patients undergoing TT-PLIF using P cages (P-TT group), 24 patients undergoing CBT-PLIF using P cages (P-CBT group), 32 patients undergoing TT-PLIF using TiP cages (TiP-TT group), and 20 patients undergoing CBT-PLIF using TiP cages (TiP-CBT group). All patients from the 4 groups underwent our unified PLIF procedure (total facetectomy, subtotal discectomy, and the same bone graft technique using the same shape cages) except for the screw trajectories and the surface materials of the cages.

Automatic segmentation of blood cells from microscopic slides: A comparative analysis.

Tissue Cell 2021 Sep 17;73:101653. Epub 2021 Sep 17.

Department of Electrical & Computer Engineering, North South University, Bashundhara, Dhaka, 1229, Bangladesh. Electronic address:

With the recent developments in deep learning, automatic cell segmentation from images of microscopic examination slides seems to be a solved problem as recent methods have achieved comparable results on existing benchmark datasets. However, most of the existing cell segmentation benchmark datasets either contain a single cell type, few instances of the cells, not publicly available. Therefore, it is unclear whether the performance improvements can generalize on more diverse datasets. Read More
