[PMID: 38150815 DOI: 10.1016/j.jmbbm.2023.106330] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2023] [Revised: 12/13/2023] [Accepted: 12/14/2023] [Indexed: 12/29/2023]
Abstract
The current study details the green synthesis of zinc oxide nanoparticles utilizing the aqueous leaf extract of Ipomoea aquatica. A straightforward, economically viable, and consistent green synthesis technique was devised for producing these nanoparticles. The resulting Zinc oxide nanoparticles underwent comprehensive characterization through XRD, FESEM, EDS, FT-IR, TGA, and DSC analyses. Additionally, the study encompassed In- vitro and In- vivo assessments, including examinations of anti-microbial effects, hemocompatibility, anti-inflammatory responses, oral toxicity in mice, and fish toxicity using the Danio rerio model. The toxicological evaluations were done using the Danio rerio model (fish toxicity) and oral toxicity studies on mice. The particle size and zeta potential were verified using a DLS study, while EDS analyses validated the elemental composition of the nanoparticles. The crystalline nature of the nanoparticles was confirmed through distinctive peaks in the XRD pattern. The HR-TEM results confirmed the particle size range obtained by the Light scattering technique. Encouraging results were observed across the range of pharmacological activities conducted, demonstrating positive outcomes in terms of anti-microbial, hemocompatibility, anti-inflammatory attributes, In-vitro cytotoxicity, oral toxicity, and fish toxicity. This study not only showcased an eco-friendly and cost-efficient method for synthesizing Zinc oxide nanoparticles but also highlighted their potential implications.

Abstract
In this work, a novel slow-release and water-retention nitrogen (N) fertilizer (SRWRNF) was prepared using moldy steamed bread-based starch-g-poly(acrylic acid-co-acrylic amide) (SBS-g-P(AA/AM)) as the skeleton and urea-formaldehyde oligomers (UF) incorporated as the slow-release N source by semi-interpenetrating methods. Various analysis technologies including scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction, thermogravimetric analysis, and differential scanning calorimetry were used to characterize the structure and properties of SRWRNFs. Swelling measurements indicated that the maximum water absorbency of SBS-g-P(AA/AM)-UF samples was 104.2 g/g in distilled water. The water-retention study showed that the SBS-g-P(AA/AM)-UF improved the maximum soil water content by 15.3-17.6% while improving soil water-retention capacity. N release experiments confirmed that SBS-g-P(AA/AM)-UF enabling offered a gradual N supply in soil. In comparison to conventional urea and UF fertilizers, the maize yield of SBS-g-P(AA/AM)-UF was increased by 20.3 and 9.7%, respectively. This study implies that the SRWRNFs provide a promising feasibility for large-scale applications in agriculture.

Abstract
Polymers from natural sources are widely used as excipients in the formulation of pharmaceutical dosage forms. The objective of this study was to extract and further characterize the tamarind gum polysaccharide (TGP) obtained from Tamarindus indica as an excipient for biomedical applications. Double distilled water was used as a solvent for the extraction of gum while Ethyl alcohol was used as an antisolvent for the precipitation. The results of the Hausner ratio, Carr’s index and angle of repose were found to be 0.94, 6.25, and 0.14, respectively, which revealed that the powder is free-flowing with good flowability. The gum was investigated for purity by carrying out chemical tests for different phytochemical constituents and only carbohydrates were found to be present. The swelling index was found to be 87 ± 1%, which shows that TGP has good water intake capacity. The pH of the 1% gum solution was found to be neutral, approximately 6.70 ± 0.01. The ash values such as total ash, sulphated ash, acid insoluble ash, and water-soluble ash were found to be 14.00 ± 1.00%, 13.00 ± 0.05%, 14.04 ± 0.57% and 7.29 ± 0.06%, respectively. The IR spectra confirmed the presence of alcohol, amines, ketones, anhydrides groups. The contact angle was <90°, indicating favorable wetting and good spreading of liquid over the surface The scanning electron micrograph (SEM) revealed that the particle is spherical in shape and irregular. DSC analysis shows a sharp exothermic peak at 350 °C that shows its crystalline nature. The results of the evaluated properties showed that TGP has acceptable properties and can be used as a excipient to formulate dosage forms for biomedical applications.

Abstract
Present communication deals with the stabilization of etoricoxib nanosuspension using Acacia chundra gum and its acrylamide-grafted and carboxymethylated copolymers. Acrylamide grafting and carboxymethylation of A. chundra gum were carried out and synthesized copolymers were characterized. Ultrasound-assisted solvent-antisolvent method was utilized to co-precipitate the stabilizers over etoricoxib nanoprecipitates. A 32 full factorial design was used to evaluate the effect of independent variables, that is, the concentration of drug and stabilizer over the dependent variables, that is, particle size (PS), and entrapment efficiency (EE%) of nanoparticles. The effect of process parameters over super saturation, nucleation, and PS were studied and the role of mixing and ultrasound radiation was correlated. FTIR, DSC, and 1H NMR analysis showed a significant difference between the copolymers. The application of stabilizers leads to the synthesis of small, spherical, no aggregated, and composite nanoparticles. PS growth analysis after 45 days showed no sign of "Ostwald repining" and aggregation. Optimized formulations prepared using A. chundra gum (formulation K9), acrylamide-grafted (formulation A8), and carboxymethylated (formulation C1) copolymers showed t80% in 190, 270, and 170 min, respectively. Cytotoxic studies showed that the formulation A8 had better control over cell growth than the pure drug against MCF-7 cell line. The results indicated that the A. chundra gum and its acrylamide and carboxymethylated copolymers can be easily synthesized and utilized for the fabrication of stabilized nanosuspension.

Abstract
This study was intended to investigate physico-chemical, rheological, and emulsifying properties of oil-in-water emulsions prepared from the Kluyveromyces marxianus mannoprotein (KMM). Also, the stress-response function of the KMM emulsions was compared with that of the whey protein concentrate (WPC) emulsions in terms of zeta potential, size, and rheology. The stress experiments were conducted at different pH (3 to 9), ionic composition (0 to 500 mM NaCl), and temperatures (30 to 90 °C). The extracted KMM with a molecular weight of 107.2 kDa had 28.8% proteins and 68.22% carbohydrates. With increasing the KMM concentration to 1.5% (w/w), the zeta potential, droplet size, and apparent viscosity of the emulsions reached -35 mV, ∼1 μ, and ∼9 mPa·s, respectively. After applying pH, ionic composition, and temperature, the KMM emulsions were more stable than the WPC emulsions. In conclusion, KMM can be used as a bioemulsifier and be more effective in stabilizing emulsions than WPC. PRACTICAL APPLICATION: Yeasts are a rich source of natural materials. In this study, we extracted mannoproteins from the yeast cell wall and evaluated their functional properties to be used as an emulsifier in oil-in-water emulsions. The results of this study confirm that the yeast-derived mannoproteins are good at stabilizing these emulsions either in the presence or absence of different environmental conditions.

Abstract
Background:
Chili peppers are widely used in many cuisines as a spice, and capsaicin is
the main component. It has been reported that capsaicin acts as an antihyperglycemic agent. However,
it shows poor aqueous solubility and bioavailability.
Objective:
The is to enhance the aqueous solubility and antihyperglycemic activity of capsaicin
through solid dispersion formulation.
Methods:
Solid dispersions were prepared by the solvent evaporation method using polyethylene
glycol 6000 (PEG 6000) as a hydrophilic carrier. Polymer-drug miscibility and drug crystallinity
were characterized through the differential thermal analysis and X-ray powder patterns analysis.
Solid dispersions were evaluated for solubility, in vitro drug dissolution and in vivo animal study in
rats.
Results:
Results of x-ray powder patterns analysis showed a considerable reduction of drug crystallinity
in solid dispersion. Differential thermal analysis result revealed a complete disappearance of
capsaicin melting onset temperature in solid dispersion. From the phase solubility data, it was observed
that the aqueous solubility of capsaicin was increased with increasing concentration of PEG
6000. Solid dispersion formulation showed considerable enhancement of in vitro release of drugs in
comparison to pure capsaicin. In vivo animal study in rats shows that the solid dispersion containing
capsaicin significantly reduced the blood glucose level in comparison to the free capsaicin.
Conclusion:
Higher anti-hyperglycemic effect of capsaicin loaded solid dispersion in comparison to
the pure drug may be due to the enhancement of aqueous solubility of capsaicin. Thus, the solid
dispersion of capsaicin showed a simple approach for capsaicin delivery with improved antidiabetic
activity.

Abstract
Background:Capsaicin is a pungent component of chili peppers that suppresses the growth of various cancer cell lines including breast cancer. However, it shows extremely low oral bioavailability due to its poor water solubility.Objective:The objective of the present work was to improve the solubility and dissolution rate of capsaicin.Methods:Solid dispersions were prepared by the solvent evaporation method using different molar ratios of capsaicin and urea (1:1, 1:2, and 1:3). Differential Scanning Calorimetry (DSC) and X-Ray Diffraction (XRD) study were used to characterize the solid dispersion. Solid dispersions were evaluated for solubility, dissolution rate and in vitro cytotoxicity in breast cancer cell lines.Results:XRD and DSC studies exhibited the reduced crystallinity of a drug in solid dispersion. Phase solubility study shows that the drug solubility increased by increasing carrier concentration. In vitro release study of the solid dispersion showed the faster dissolution of a drug with increasing carrier concentration. Solid dispersion formulation effectively inhibited the growth of MCF-7 human breast cancer and MDA-MB-231 triple negative human breast cancer cells in an MTT assay that measures metabolic activity, but only slightly decreased cell viability when compared to capsaicin alone.Conclusion:The present study demonstrated that solid dispersion of capsaicin in PEG 6000 overcomes the problems related to the poor aqueous solubility of this drug and improving its dissolution rate.

Abstract
Objective:
The presence of capsaicin in the diet has been revealed to enhance energy expenditure
and it has been used in anti-obesity therapy. The present work investigated the potential antihyperlipidemic
effect of capsaicin loaded hydrogel beads on hyperlipidemic rats. Hydrogels are three
dimensional, hydrophilic, polymeric networks capable of imbibing large amounts of water or biological
fluids.
Methods:
Capsaicin loaded hydrogel beads were prepared by the ionotropic gelation method using
Aluminium Chloride (AlCl₃) as a cross-linking agent. The characterization of hydrogel beads was carried
out by X-ray Diffraction (XRD), Differential Scanning Calorimetry (DSC), and Scanning Electron
Microscopic (SEM) analysis.
Results:
The surface morphology revealed that the prepared beads were spherical in shape. XRD and
DSC study of the hydrogel beads revealed that the drug was homogeneously dispersed in the hydrogel
matrix. The beads showed pH sensitive behavior and when the medium pH was changed from 1.2 to
7.4, the capsaicin release was considerably increased. 100mg/kg body weight of Triton was injected intraperitoneally
in rats to induce hyperlipidemia and it showed elevated levels of serum cholesterol and
triglyceride. Capsaicin loaded hydrogel beads were administered to normal and hyperlipidemic rats for
7 days and the prepared hydrogel beads were significantly reduced high lipid profile in comparison to
free capsaicin.
Conclusion:
The results clearly demonstrated that hydrogel beads can be used as a potential carrier for
delivery of capsaicin to reduce lipid profile.
