The KNOX transcription factors, crucial for leaf and meristem development, are categorized into two main classes, with class I proteins closely related to green algae homologs. An examination of 48 species identified 394 KNOX proteins, with KNATM proteins found only in Eudicots, and certain plants like Glycine max having a significant number of KNOX paralogs. Gene expression analysis in G. max reveals that the expansion in gene number leads to functional diversification, with class II proteins showing broader expression than class I proteins.
Given the emphasis on community engagement and collaboration in addressing the disparities and inequities in stroke incidence and care, how effective have community-based participatory research approaches been in mitigating these challenges, and what strategies have been most successful in promoting diversity within vascular neurology?
The findings challenge the conventional belief that surround suppression in the cat primary visual cortex (V1) arises from increased lateral inhibition. Instead, the study suggests that suppression comes from a reduction in excitation, not from the thalamic input but from the circuitry of V1 itself. Furthermore, this behavior supports the idea that V1 operates as an inhibition-stabilized network (ISN), shedding light on the underlying mechanisms of visual processing in the cortex and offering explanations for observed variability in neural responses.
A new method has been developed for directly capturing hexahistidine (His6) tagged proteins from unclarified mammalian cell feed streams using immobilized metal affinity chromatography (IMAC). This technique, exemplified with Chinese Hamster Ovary (CHO) cells, bypasses the need for expensive and tedious centrifugation or filtration steps by using radial flow chromatography with agarose resin beads. The method successfully recovered 71% of His-tagged carcinoembryonic antigen (CEA) from unclarified feed, paving the way for efficient purification of glycosylated recombinant proteins from mammalian cells.
Interesting talk! Given the urgency of the situation and the time typically required to develop new drugs for covid-19 and its variants, repositioning already-approved drugs seemed as an attractive option.

Angiogenesis, the formation of new blood vessels, is essential for physiological functions and tissue repair. Despite numerous strategies promoting tissue regeneration via angiogenesis, none have reached clinical significance. This review delves into recent therapies, from cell-based to biomaterial techniques, emphasizing their potential in disease treatments and the promising future of angiogenesis in regenerative medicine.
“Green Composites” here refer something natural sources not just only biodegradable. For instance, chitin, chitosan, alginate, and collagen are green polymers widely used for manufacturing composites for hard tissue repair.
One of the challenges in tissue engineering is creating biomaterials that can effectively mimic the complex microenvironment of natural tissues and promote proper cell behavior and tissue regeneration. How do researchers address this challenge when working with materials like agarose?
Very interesting review article. Periodontitis, a prevalent oral disease causing tooth loss, involves a complex microenvironment affecting immune cells and stem cells. Guided tissue regeneration (GTR) aims to restore healthy tissue using biomaterials and stem cells post-inflammation. Despite progress, challenges persist, and this review highlights potential strategies for overcoming obstacles in periodontal tissue engineering.
A gelatin-based tough hydrogel (GBTH) with strong crystalline domains has been developed, addressing limitations like poor biocompatibility in existing hydrogels. Successfully applied to rabbit tendons, GBTH's biocompatibility and quick tissue recovery potential highlight its promise for effective tissue regeneration. This innovation marks progress in creating highly compatible tough hydrogels.
