Three domains characterize the Myotubularin 1 (MTM1) protein: a lipid-binding N-terminal GRAM domain, a phosphatase domain, and a coiled-coil domain which is essential for dimerization of Myotubularin homologues. While mutations in the phosphatase domain of MTM1 are frequently observed, variations in the sequence's other two domains are equally prevalent in XLMTM cases. We assembled a series of missense mutations in MTM1 to assess their profound effects on protein structure and function through both in silico and in vitro methodologies. A conspicuous deficiency in substrate binding, along with the elimination of phosphatase function, was observed in a small number of mutants. The potential for long-reaching effects of mutations within non-catalytic domains on phosphatase activity was observed. Novel coiled-coil domain mutants have been characterized in XLMTM literature for the first time in this study.

Among polyaromatic biopolymers, lignin holds the distinction of being the most abundant. Its extensive and adaptable chemical nature has sparked the development of numerous uses, such as the creation of functional coatings and films. The lignin biopolymer's capacity for replacing fossil-based polymers can be further leveraged by incorporating it into new material solutions. Lignin's intrinsic and unique traits enable the incorporation of various functionalities, including UV-blocking, oxygen scavenging, antimicrobial properties, and protective barriers. Consequently, a broad spectrum of applications has been proposed, including polymer coatings, adsorbents, paper sizing additives, wood veneers, food packaging materials, biocompatible substances, fertilizers, corrosion inhibitors, and anti-fouling membranes. In the pulp and paper industry, substantial amounts of technical lignin are currently produced, while biorefineries of the future promise an even greater array of derived products. Accordingly, the development of novel applications for lignin is undeniably essential, both technologically and from an economic standpoint. The current state of research on lignin-based functional surfaces, films, and coatings is summarized and discussed in this review article, with a significant focus on their formulation and practical application procedures.

A new method for stabilizing Ni(II) complexes on modified mesoporous KIT-6 was employed in this paper to successfully synthesize KIT-6@SMTU@Ni, a novel and environmentally benign heterogeneous catalyst. In order to characterize the catalyst (KIT-6@SMTU@Ni), various analytical techniques such as Fourier transform infrared spectroscopy (FT-IR), Brunauer-Emmett-Teller (BET) calculation, X-ray diffraction (XRD), atomic absorption spectroscopy (AAS), energy-dispersive X-ray spectroscopy (EDS), X-ray mapping, thermogravimetric analysis (TGA) and scanning electron microscopy (SEM) were employed. After the complete characterization process, the catalyst was successfully used for the synthesis of 5-substituted 1H-tetrazoles and pyranopyrazoles. Furthermore, benzonitrile derivatives and sodium azide (NaN3) were utilized in the synthesis of tetrazoles. In a reasonable time frame (1.3-8 hours), the KIT-6@SMTU@Ni catalyst facilitated the synthesis of all tetrazole products with outstanding yields (88-98%), high turnover numbers (TON), and turnover frequencies (TOF), effectively showcasing its practical utility. Moreover, pyranopyrazoles were synthesized via the condensation of benzaldehyde derivatives with malononitrile, hydrazine hydrate, and ethyl acetoacetate, achieving high turnover numbers (TON), turnover frequencies (TOF), and excellent yields (87-98%) within suitable reaction times (2-105 hours). The KIT-6@SMTU@Ni component can undergo five operational cycles without requiring reactivation. Remarkably, this plotted protocol offers numerous advantages such as the use of green solvents, the use of readily available and affordable materials, excellent catalyst separation and reusability, a short reaction time, a high product yield, and a simple workup procedure.

Chemo-photothermal therapy, with its highly efficient nature and reduced side effects, holds great promise for applications in cancer treatment. A nano-drug delivery system exhibiting cancer cell targeting, high drug loading capabilities, and remarkable photothermal conversion is of considerable value. Fe3O4-modified graphene oxide (MGO) was successfully coated with folic acid-grafted maltodextrin polymers (MDP-FA) to create a novel nano-drug carrier, MGO-MDP-FA. The nano-drug carrier leveraged the cancer cell-targeting properties of FA and the magnetic targeting properties of MGO. Through the synergistic actions of hydrogen bonding, hydrophobic interactions, and other interactions, a large amount of doxorubicin (DOX) was successfully loaded, culminating in a maximum loading amount of 6579 mg/g and a loading capacity of 3968 wt%. The application of near-infrared irradiation to MGO-MDP-FA resulted in a notable thermal ablation of tumor cells in vitro, directly linked to the strong photothermal conversion properties of MGO. Compound MGO-MDP-FA@DOX showcased remarkable chemo-photothermal tumor inhibition in vitro, demonstrating an 80% tumor cell killing efficiency. Through the construction of the MGO-MDP-FA nano-drug delivery system, this paper presents a promising nano-platform to synergistically treat cancer via combined chemo-photothermal therapy.

Employing Density Functional Theory (DFT), the interaction of cyanogen chloride (ClCN) with the carbon nanocone (CNC) surface was scrutinized. This research's findings demonstrate that pristine CNC, owing to its minimal modifications in electronic properties, isn't an optimal material for detecting ClCN gas. Carbon nanocones' attributes were enhanced through the application of multiple methodologies. Pyridinol (Pyr) and pyridinol oxide (PyrO) were used to functionalize the nanocones, and they were subsequently decorated with boron (B), aluminum (Al), and gallium (Ga). In addition, the nanocones were also infused with the same third-group metals—boron, aluminum, and gallium—as dopants. The simulation's findings suggested that incorporating aluminum and gallium atoms led to encouraging outcomes. Following a thorough optimization procedure, two stable configurations were identified for the interaction between ClCN gas and the CNC-Al and CNC-Ga structures (configurations S21 and S22), exhibiting Eads values of -2911 and -2370 kcal mol⁻¹ respectively, utilizing the M06-2X/6-311G(d) level of theory.
