In silico analysis of novel Triacontafluoropentadec-1-ene as a sustainable replacement for dodecane in fisheries microplastics: Molecular docking, dynamics simulation and pharmacophore studies of acetylcholinesterase activity.

Plastics play an essential role in modern fisheries and their degradation releases micro- and nano-sized plastic particles which further causes ecological and human health hazards through various environmental contamination pathways and toxicity mechanisms, which can cause respiratory problems, cancer, reproductive toxicity, endocrine disruption and neurological effects in humans. This study utilized various bioinformatics tools through multi-step computational analyses to investigate the interactions between prevalent fisheries microplastics and the key protein receptor acetylcholinesterase (AChE), which is associated with neurotoxicity, as it can interfere with nerve impulses and muscle control. Our results indicate that the binding of seven polymers within AChE's active site, with dodecane and polypropylene exhibited highest affinity with hydrogen bonding were observed through Molecular docking of different program (PyRx) and servers (CB-Dock, eDock) then the stability of AChE-dodecane and AChE-polypropylene complexes were observed through MD simulations for 100 ns.

Isolation, structural characterization of (1 → 4), (1 → 6)-α-D-glucan from Dioscorea Alata and synthesis and catalytic activity studies of (1 → 4), (1 → 6)-α-D-glucan derived carbon dots.

Herein, a straightforward, productive protocol was adopted for the synthesis of carbon dots (CDs) by a simple microwave-assisted technique from (1 → 4), (1 → 6)-α-D-glucan polysaccharide (DAPS). The isolation and structural characterization of (1 → 4), (1 → 6)-α-D-glucan from the aqueous extracting of the Diascorea Alata was described here. The photo-physical and morphological studies of the prepared high quantum yield (27.

Homeotic transformation of tail to limbs: A novel morphogenesis in the framework of self-organization and reprogramming of cell fate during appendage regeneration.

Homeotic transformation of tail to hindlimbs in anuran tadpoles is a manifestation of the reprogramming of positional information in the event of tail regeneration. Such discovery of homeosis is of particular interest considering its occurrence in a vertebrate under the influence of a morphogen which represents a self-organizing system in the context of developmental and regenerative studies. This article reviews homeotic transformation of tail to hindlimbs including pelvic girdles induced by retinoic acid (RA) /vitamin A palmitate during tail regeneration under the scope of self-organization and the role of blastema as an organizer.

Deubiquitinating enzymes in breast cancer: analysis of gene expression and metastatic correlation.

Breast cancer, the most prevalent cancer in females, is a heterogeneous disease with various molecular subtypes, which presents challenges in diagnosis and treatment. Ubiquitination is one of the most critical post-translational protein modifications, that plays regulatory roles in numerous cellular processes including cell cycle progression, DNA replication & repair, apoptosis, transcription regulation, protein localization, trafficking and signal transduction. This modification can be reversed by deubiquitinases, or DUBs, a superfamily of cysteine proteases and metalloproteases that cleave ubiquitin-protein bonds.
