Despite recent advancements in cancer therapies, challenges such as severe toxic effects, non-selective targeting, resistance to chemotherapy and radiotherapy, recurrence of metastatic tumors persist. Consequently, there has been considerable effort explore innovative anticancer compounds, particularly immunotherapy, which offer the potential for enhanced biosafety efficacy prevention treatment. One avenue exploration involves miRNA-34 (miR-34) family, known its ability inhibit tumorigenesis across various cancers. Dysregulation miR-34 observed several human cancers, it is recognized a tumor suppressor microRNA due synergistic interaction with well-established p53. However, have arisen therapeutic application miR-34a. These include susceptibility degradation by RNase serum, limiting penetrate capillary endothelium reach target cells, well reports immunoreactive adverse reactions. Furthermore, unexpected side effects may occur, accumulation miRNAs healthy tissues interactions serum proteins on nano-vector surfaces, nanoparticle breakdown bloodstream shearing stress, unsuccessful extravasation nanocarriers cells owing interstitial fluid pressure. these challenges, miR-34a remains promising candidate therapy, other members family also shown inhibiting cell proliferation.

The strong demand for biological materials in the food industry places chitosan at forefront of other biopolymers. present study aims to evaluate antifungal properties extracted from shrimp shell waste (Parapenaeus longirostris) against post-harvest strawberry (Fragaria × ananassa) spoilage fungi. physicochemical characteristics (DD, Mw, and solubility) were determined. In addition, functional studied by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM). effect on mycelial growth spore germination Aspergillus niger, Botrytis cinerea, Fusarium oxysporum, Rhizopus stolonifer was evaluated. Yield, degree deacetylation, molecular weight, solubility 21.86%, 83.50%, 180 kDa, 80.10%, respectively. A deacetylation 81.27% calculated FTIR spectrum a crystallinity index 79.83% determined pattern. SEM images showed combination fibrous porous structure. At 3% chitosan, inhibition rates A. B. F. R. ranged 81.37% 92.70%. same concentration, percentages isolated fungi 65.47% 71.48%. activity highly dose-dependent. As natural polymer, offers convincing alternative synthetic antimicrobials preservation strawberries. Its potential lies its ability inhibit

This study attempts to understand the relationship between structural and physicochemical changes of clay modified by a chitosan intercalation, valorize clay-chitosan composites for wastewater treatment purpose. More precisely, main aim was characterization modeling properties clay-polymer (especially bentonite-chitosan composites) versus concentration added intercalation. We first developed method intercalating into matrix, with different polymer concentrations (6g/l, 12g/l, 18g/l, 24g/l, 27g/l 30g/l). Second, we carried out based on X-Rays Diffraction (XRD), Fourier Transform Infrared (FTIR) Scanning Electric Microscopy (SEM). In particular, results these analyses show that measured pores within 6g/l 30g/l are nanometric order, while composite at 12g/l is rather microscopic order. Third, XRD measurements allow determination interlayer space (basal distance) particles size concentration. For basal distance, have demonstrated existence five regimes depending value concentration, namely (i) dilute regime, (ii) semi-dilute (iii) well-regime, (iv) second regime (v) saturation regime. Finally, may be used as kinds filtration membranes wastewater, retaining, example, dye whose adsorption quantity found improved an amount 76.92%.

Nowadays, plastic contamination worldwide is a concerning reality that can be addressed with appropriate society education as well looking for innovative polymeric alternatives based on the reuse of waste and recycling circular economy point view, thus taking into consideration future world without quite impossible to conceive. In this regard, in review, we focus sustainable materials, biodegradable bio-based polymers, additives, micro/nanoparticles used obtain new environmentally friendly polymeric-based materials. Although polymers possess poorer overall properties than traditional ones, they have gained huge interest many industrial sectors due their inherent biodegradability natural environments. Therefore, several strategies been proposed improve extend applications. Blending strategies, development composites nanocomposites, shown promising perspectives improving performances, emphasizing biopolymeric blend formulations micro nanoparticles produce fully The Review also summarizes recent developments blends, composites, nanocomposite plasticization, particular naturally derived plasticizers chemical modifications increase compatibility matrices. current state art most important reviewed, mainly focusing synthesis processing methods scalable sector, such melt solution blending approaches like melt-extrusion, injection molding, film forming electrospinning, among others, neglecting degradation processes.

Due to their biocompatibility and non-toxicity, biopolymer-based films hold significant importance in bioengineering. It is imperative comprehend the influence of chitosan molecular weight filler materials nature on crystalline structure subsequent effect film properties. The aim this research was determine how carbon nanotubes embedded within can significantly improve performance produced by solvent-casting technique. Four probe measurements demonstrated that medium-molecular-weight chitosan/carbon displayed an electrical conductivity value 0.0132 S cm-1, resulting with a low sheet resistance 0.0156 mΩ/Υ. Based XRD findings, it has been containing have shifted (002) plane towards higher angles, favoring crystal form II, which could be responsible for enhanced mechanical performance. Structural characteristics, such as lattice strain (e), grain size (D), dislocation density, calculated using Williamson-Hall method, chitosan/CNTs samples best quality. SEM images revealed nanotube diameters ranging from 140 300 nm, suggesting effectively wrapped along nanotubes. Our results indicate developing chitosan-wrapped introduces them potential bioengineering biomedical research.
