• Crystalline structures present in starches are hexagonal or/and orthorhombic. • A-Type starches contain an orthorhombic structure. • B-type starches contain a hexagonal structure. • A complete indexing of the orthorhombic and hexagonal structures was done. This work reports an X-ray diffraction analysis of the crystalline phases present in starch. Crystallographic studies using Grazing Incidence X-ray Diffraction (GIXRD) were carried out for defatted isolated starches from amaranth and avocado pits. These studies confirm previous ones that reported the occurrence of the A-type orthorhombic and B-type hexagonal structures, in which a partial indexing of the diffraction peaks recorded was reported for the orthorhombic structure. In contrast, the indexing of the diffraction pattern of the hexagonal structure has not been previously reported. The present study provides the identification and a complete indexing of the orthorhombic and hexagonal structures present in starches, which would facilitate the correct identification of these two crystalline structures in materials where starch is present.

Pepper originated from the Capsicum genus, which is recognized as one of the most predominant and globally distributed genera of the Solanaceae family. It is a diverse genus, consisting of more than 31 different species including five domesticated species, Capsicum baccatum, C. annuum, C. pubescen, C. frutescens, and C. chinense. Pepper is the most widely used spice in the world and is highly valued due to its pungency and unique flavor. Pepper is a good source of provitamin A; vitamins E and C; carotenoids; and phenolic compounds such as capsaicinoids, luteolin, and quercetin. All of these compounds are associated with their antioxidant as well as other biological activities. Interestingly, Capsicum fruits have been used as food additives in the treatment of toothache, parasitic infections, coughs, wound healing, sore throat, and rheumatism. Moreover, it possesses antimicrobial, antiseptic, anticancer, counterirritant, appetite stimulator, antioxidant, and immunomodulator activities. Capsaicin and Capsicum creams are accessible in numerous ways and have been utilized in HIV-linked neuropathy and intractable pain.

2021-04-01 Abstract  
In the search for an alternative treatment to reduce antimicrobial resistance, bacteriocins shine a light on reducing this problem in public and animal health. Bacteriocins are peptides synthesized by bacteria that can inhibit the growth of other bacteria and fungi, parasites, and viruses. Lactic acid bacteria (LAB) are a group of bacteria that produce bacteriocins; their mechanism of action can replace antibiotics and prevent bacterial resistance. In veterinary medicine, LAB and bacteriocins have been used as antimicrobials and probiotics. However, another critical role of bacteriocins is their immunomodulatory effect. This review shows the advances in applying bacteriocins in animal production and veterinary medicine, highlighting their biological roles.

2020-06-23 Abstract  
Plants have been used since ancient times to cure certain infectious diseases, and some of them are now standard treatments for several diseases. Due to the side effects and resistance of pathogenic microorganisms to antibiotics and most drugs on the market, a great deal of attention has been paid to extracts and biologically active compounds isolated from plant species used in herbal medicine. Artemisia absinthium is an important perennial shrubby plant that has been widely used for the treatment of several ailments. Traditionally, A. absinthium has always been of pharmaceutical and botanical importance and used to manage several disorders including hepatocyte enlargement, hepatitis, gastritis, jaundice, wound healing, splenomegaly, dyspepsia, indigestion, flatulence, gastric pain, anemia, and anorexia. It has also been documented to possess antioxidant, antifungal, antimicrobial, anthelmintic, anti-ulcer, anticarcinogenic, hepatoprotective, neuroprotective, antidepressant, analgesic, immunomodulatory, and cytotoxic activity. Long-term use of A. absinthium essential oil may cause toxic and mental disorders in humans with clinical manifestations including convulsions, sleeplessness, and hallucinations. Combination chemotherapies of artemisia extract or its isolated active constituents with the currently available antibabesial or anti-malarial drugs are now documented to relieve malaria and piroplasmosis infections. The current review examines the phytoconstituents, toxic and biological activities of A. absinthium.

2021-12-28 Abstract  
The use of antibiotics in animal production are widely used for disease treatment, health protection, and as growth promoters. Common antibiotics used in veterinary medicine are excreted and eliminated through the sewage system, contaminating water and soil with negative effects on agricultural activities. This systematic review focuses on the trend of research works on antibiotic residues, evaluating antibiotics used in livestock production and their excretion in animal products and in environmental matrices such as water and soil. Our database was composed of 165 articles, reporting the concentration of antibiotic residues found in the environment, livestock (cow, sheep, pig, horse, chicken, rabbit, goat), aquatic and terrestrial animal tissues, animal products (milk and eggs), wastewater, and soil. The documents were obtained from Asia, Africa, North America, South America, Europe, and Oceania. A descriptive analysis of antibiotic residues found worldwide was analyzed according to each of the variables used such as antibiotic family, name, concentration (% and mg/kg or ppm), and country and continent where the residue was found. The descriptive analysis was carried out using the “describe” function of psych package and pirate plots were drawn. According to our study, the main antibiotics used worldwide in animal production are sulfonamides, tetracyclines, quinolones, penicillin, and cephalosporins. At present, despite the trends of increased regulations on the use of antibiotics worldwide, antibiotics are still utilized in food animal production, and are present in water and soil, then, there is still the misuse of antibiotics in many countries. We need to become aware that antibiotic contamination is a global problem, and we are challenged to reduce and improve their use.

2020-06-02 Abstract  
In recent years, iron oxide nanoparticles have demonstrated great potential in biomedical applications due to their non-toxic role in biological systems. Also, the magnetic and semiconductor properties of iron oxide nanoparticles can lead to multifunctional applications in medicine. These nanoparticles have been developed as antibacterial, antifungal, and anticancer. For cancer treatment and diagnosis, iron oxide nanoparticles have been functionalized with drugs. However, many of those drugs have been related to adverse effects on health. On the other hand, phytochemicals from extracts of plants have been used as an alternative for the functionalization of these nanoparticles preventing negative effects. The main advantage of these nanoparticles is the high biodistribution in the organism compared with other drug delivery systems. The magnetism of iron oxide nanoparticles has been used in cancer treatment and diagnosis, for example, thermoablation, hyperthermia, and contrast media in magnetic resonance imaging. Therefore, this work aimed to discuss the methods for the synthesis of iron oxide nanoparticles, the different kinds of coatings used to functionalize them, and the different applications they have had in cancer treatment and diagnosis.

Metal-organic frameworks are novel materials with specific pore-size that presents unlimited applications in material sciences. The presence of metallic ions in the MOF structure offers a redox active material with electrocatalytical properties towards diverse biomolecules, organic compounds and heavy metals. This property can be combined with nanomaterials for create cheap carbon based electrodes with enhanced electroanalytical features (like selectivity, good low detection limits and high stability on alkali or acid media). In this review, we have collected recent information about MOF applications in carbon electrodes and fundamental aspects on the electroactive MOFs design, fabrication of MOF-modified carbon based electrodes, characterization of electrodes and examples of direct sensing with MOF-modified electrodes.

In the present research, hybrid Au-ZnO one-dimensional (1-D) nanostructures were grown on silicon substrates with an Al-doped ZnO (AZO) seed layer (Ultrasonic Spray Pyrolysis: USP grown) and no seed layer (NSL) using two different catalytic gold films of 2 nm and 4 nm, respectively. Consequently, such 1-D nanostructures growth was associated with the vapor-liquid-solid (VLS) and vapor-solid (VS) processes. Scanning electron microscopy (SEM) imaging analysis confirms that heat treatment triggered Au nanoparticles nucleation with varying diameters. The Au nanoparticles size and underneath seed layer texture strongly affect the morphology and aspect ratio of 1-D ZnO nanostructures. The seed layer (1-D USP) sample resulted in the growth of longer nanowires (NWs) with a high aspect ratio. The NSL sample showed the formation of nanorods (NRs) with a low aspect ratio mainly via VS growth process. X-ray diffraction (XRD), X-Ray photoelectron spectroscopy (XPS), and photoluminescence (PL) analysis also revealed the differences in the NWs and NRs properties and confirmed VLS and VS growth mechanisms. CO2 gas sensing performance at different concentrations was demonstrated, and NWs with seed layer showed a relatively higher sensing response. In contrast, NSL samples (NRs) exhibited two times faster response. A detailed gas sensing mechanism with different CO2 adsorption modes based on properties of 1-D nanostructures has been discussed. Currently, CO2 sensing and capturing are critical topics in the green transition framework. The present work would be of high significance to the scientific field of NW growth and fulfill the urgent need for CO2 gas sensing.

2021-03-11 Abstract  
Cosmic rays with energies up to a few PeV are known to be accelerated within the Milky Way1,2. Traditionally, it has been presumed that supernova remnants were the main source of these very-high-energy cosmic rays3,4, but theoretically it is difficult to accelerate protons to PeV energies5,6 and observationally there simply is no evidence of the remnants being sources of hadrons with energies above a few tens of TeV7,8. One possible source of protons with those energies is the Galactic Centre region9. Here, we report observations of 1–100 TeV γ rays coming from the ‘Cygnus Cocoon’10, which is a superbubble that surrounds a region of massive star formation. These γ rays are likely produced by 10–1,000 TeV freshly accelerated cosmic rays that originate from the enclosed star-forming region Cyg OB2. Until now it was not known that such regions could accelerate particles to these energies. The measured flux likely originates from hadronic interactions. The spectral shape and the emission profile of the Cocoon changes from GeV to TeV energies, which reveals the transport of cosmic particles and historical activity in the superbubble. Following HAWC observations of the Cygnus Cocoon, massive star-forming regions can now be considered to be sources of very-high-energy (TeV to PeV) Galactic cosmic rays.

2021-02-01 Abstract  
One of the challenges in modern society is the reduction of meat consumption as well as the formulation of new meat products, considering health and sustainability aspects. In this regard, mushrooms are considered a promissory source of bioactive compounds to be used in the production of healthier meat products. Mushrooms have antimicrobial and antioxidant properties, which can improve the self-life of meat products. This review shows that a substantial improvement in terms of protein, dietary fiber and ash content in meat products can be achieved by incorporating different types of mushrooms without significantly affecting their physico-chemical properties. Moreover, due to high percentage of dietary fiber, easily digestible protein and a meat-like texture, mushroom is an interesting choice to replace salt, phosphates, protein and fat in the formulation of meat products. Finally, the presence of high contents of free amino acids in mushroom can enhance the sensorial properties of meat products.

AbstractColloidal dispersions exhibit rich equilibrium and nonequilibrium thermodynamic properties, self-assemble into diverse structures at different length scales, and display transport behavior under bulk conditions. In confinement or under geometrical restrictions, new phenomena emerge that have no counterpart when the colloids are embedded in an open, noncurved space. In this review, we focus on the effects of confinement and geometry on the self-assembly and transport of colloids and fluidized granular systems, which serve as model systems. Our goal is to summarize experiments, theoretical approximations and molecular simulations that provide physical insight on the role played by the geometry at the mesoscopic scale. We highlight particular challenges, and show preliminary results based on the covariant Smoluchowski equation, that present promising avenues to study colloidal dynamics in a non-Euclidean geometry.

2025-03-05 Abstract  
This paper develops a strategic framework that integrates the theoretical perspectives of evolutionary economic geography and economic complexity to identify green export opportunities. By combining feasibility factors—such as green specialization, relatedness, and trade inertia—with desirability criteria like income, equity, and low emissions, the framework offers a comprehensive approach to identify green export diversification. The empirical application, focused on the Southern Cone (Argentina, Brazil, Chile, Paraguay, and Uruguay), suggests that economies should prioritize green opportunities aligned with their existing capabilities, gradually expanding into higher-risk, higher-return options. The study provides tailored green export diversification portfolios for each country, identifying key opportunities in renewable energy products for Argentina and Brazil, lithium-related inputs for Chile, biofuels for Paraguay, and green hydrogen for Uruguay. These findings offer valuable insights for the design of public policies aimed at fostering green export diversification.

Precipitation-hardenable stainless steels (PHSSs) are widely used in various applications in the aerospace industry. PHSSs are used in various parts that need to combine mechanical properties with corrosion resistance when aircrafts are in corrosive environments. This study aimed to analyze the corrosion kinetics of CUSTOM 450 and AM 350 stainless steels that were passivated in acid baths for a period of 120 min at temperatures of 25 and 50 °C and then immersed in solutions containing 1 wt. % sulfuric acid (H2SO4) and 5 wt. % sodium chloride (NaCl). The electrochemical technique used was cyclic potentiodynamic polarization (CPP) based on ASTM G61-86. Microstructural characterization was performed via optical microscopy (OM) and scanning electron microscopy (SEM). The results revealed that the potentiodynamic polarization curves have two distinct corrosion mechanisms. The immersion of PHSSs in the H2SO4 solution produces an activation–passivation reaction. The NaCl solution has pseudopassivation (unstable passivation film). The values of the icorr current densities in the solutions of sodium chloride and sulfuric acids are between 10−3 and 10−5 mA/cm2; the stainless steels are susceptible to localized pitting corrosion in both test solutions, with positive hysteresis in the CPP.

Aquaculture is the fastest-growing food production sector. However, it faces significant challenges, including demand from a growing global population, which is estimated to reach 10.4 billion by the year 2100, disease outbreaks, environmental impacts, and the overuse of antibiotics. To address these issues, sustainable alternatives such as the use of microorganisms (probiotics, bacteriophages, and genetically modified microorganisms) have gained attention. This review examines the effects of these microorganisms on fish aquaculture, focusing on their potential to improve growth, health, and disease resistance while reducing environmental impacts. Probiotics, particularly lactic acid bacteria and yeasts, have been shown to enhance immune responses, digestive enzyme activity, and nutrient absorption in fish. Bacteriophages offer a promising alternative to antibiotics for controlling bacterial pathogens, with studies demonstrating their efficacy in reducing mortality rates in infected fish. Additionally, genetically modified microorganisms (GMMs) have been explored for their ability to produce beneficial compounds, such as enzymes and antimicrobial peptides, which can improve fish health and reduce the need for chemical treatments. Despite their potential, challenges such as regulatory hurdles, public acceptance, and environmental risks must be addressed. This review highlights the importance of further research to optimize the use of microorganisms in aquaculture and underscores their role in promoting sustainable practices. By integrating these biological tools, the aquaculture industry can move towards a more sustainable and environmentally friendly future.

In this research work, the direct roastingRoasting reaction of pure α-spodumene (LiAlSi2O6) with NaFNaF through thermodynamicThermodynamics simulationSimulation using the Equilib module included in the FactSage 8.2 software was studied. The molar ratios (RM) of LiAlSi2O6:NaFNaF: 1:0.5, 1:0.6, 1:0.7, 1:0.8, 1:0.85, 1:1, and 1:2.0 were analyzed in the temperature range (50–1200) °C and pressure of 1 atmosphere to determine the chemical species in equilibrium every 50 °C by Gibbs energy minimization. The most thermodynamically stable chemical species formed in all RMs were: LiF, NaAlSi3O8, and NaAlSiO4. The maximum percentage yield (PY) for the LiF species was 99% in the solid state starting at 250 °C, and in the liquid state at temperatura ≥850 °C for the 1:1 RM, with an excess of NaFNaF of 0.0008%. The obtained results demonstrated that direct roastingRoasting of α-spodumene using NaFNaF is thermodynamically favourable in the studied temperature range, which was confirmed by the formation of lithiumLithium fluoride in the solid or liquid phase and allowed to propose the reaction mechanism.

PyritePyrite is an iron disulfide (FeS2) associated with base metal sulfides. During flotationFlotation and due to their hydrophobicHydrophobic properties, it occurs abundantly in the concentrate. In this research work, we seek to alter the surface properties of this species to hydrophilic ones by adding tannic acidTannic acid (TA), evaluating the collectorlessCollectorless flotationFlotation of a single phase of FeS2, using different pH values 6.0, 7.0, 9.0 and proportions of AT 50, 100, 200, 400, 600 and 800 mg/L. The results show that during flotationFlotation in the absence of AT, the pyritePyrite presents hydrophobicHydrophobic properties, obtaining a concentrate with around 35% w/w, the addition of AT and for all the concentrations evaluated depresses the FeS2, when there are 800 mg/L of AT in the pulp, the concentrate obtained contains 12.7% w/w, while with 50 mg/L of AT there is 15.8% w/w, the tests were carried out at oxidizing potentials of +350 mV.

In this work, the effect of the amount of TG and pH on the flotationFlotation efficiency of a single mineralMineral phase is explored, to determine whether TG activates or depresses PbS. The results found show that TG improves flotationFlotation compared to tests with only frother agent and with 0.1 g/L xanthateXanthate without TG. This reagent activates the mineralMineral surface and at pH 11 with 0.25 g/L of TG and 0.1 xanthateXanthate, 95% w/w of flotationFlotation is obtained, while for the test without TG, there is only 70% w/w of PbS flotationFlotation. pH values ​​7.7 and 10 similarly improve efficiency, obtaining values ​​of 90% w/w of PbS flotationFlotation in the presence of 0.25 and 0.75 g/L of TG, respectively, and with pulp potentialsPulp potential of +26 mV.

Background/Objectives: Alopecia is a hair disorder with a significant impact on quality of life, and its incidence has been increasing in recent years. Current therapeutic options are limited and may cause adverse side effects, highlighting the need to develop safer and more effective formulations. Therefore, the objective of this study was to evaluate the effect of a formulation based on the bioactive fraction of Bacopa procumbens (BFNB), conjugated with gold nanoparticles, on hair growth through the modulation of apoptosis in C57BL/6 mice. Methods: The potential biological activities of the secondary metabolites of B. procumbens present in BFNB were analyzed in silico. In vivo experiments evaluated the expression of pro-apoptotic markers p53, caspase 3-p11, caspase 9-p10, and Bax, as well as anti-apoptotic marker Bcl-2, through Western blotting. Immunohistochemistry further assessed the expression and localization of some of these markers. Additionally, molecular docking and interactomic analyses were performed, complemented by functional enrichment, to explore molecular pathways modulated by the evaluated proteins. Results: In silico analyses suggested that BFNB metabolites are involved in the modulation of hair growth, hair fragility, and apoptosis. This finding was supported by in vivo experiments in mice, where BFNB significantly decreased the expression of p53, caspase 3-p11, caspase 9-p10, and Bax while increasing Bcl-2 levels. Immunohistochemistry showcased a reduction in pro-apoptotic markers in dermal and follicular bulb cells. Furthermore, molecular docking studies identified BFNB metabolites as potential direct modulators of these key proteins, strengthening evidence of their role in apoptotic regulation. The interactomic analysis highlighted 50 proteins associated with apoptosis, and functional enrichment underscored key processes such as p53 signaling, regulation of the apoptosome, and mitochondrial membrane involvement in the intrinsic apoptosis mechanism, among other pathways. Conclusions: This study demonstrates that BFNB effectively modulates apoptosis through key molecular mechanisms, highlighting its potential as an innovative therapy for promoting hair growth.

Background: Optic nerve sheath hemangiomas (ONSHs) are rare vascular tumors from the blood vessels surrounding the optic nerve, accounting for <1% of optic tumors and 0.5% of vascular malformations. Although benign, their location near the optic nerve poses a risk of significant nerve damage and vision loss. Symptoms often include visual disturbances, eye pain, and strabismus, making it difficult to make a diagnosis. Advances in imaging, especially magnetic resonance imaging (MRI), have improved early detection and diagnosis. In addition, insights into the molecular mechanisms, including endothelial signaling and angiogenesis, have facilitated the development of more effective treatments, such as targeted therapies and minimally invasive surgical options. Case Description: We present the case of a 57-year-old woman who experienced progressive left-eye swelling, increased tearing, and declining visual acuity. Imaging studies, including MRI and computed tomography scans, revealed a left intraconal mass suggestive of ONSH. A transcranial-modified orbitofrontal approach was employed for tumor resection due to its proximity to vital structures. Postoperative histopathology confirmed hemangioma. At 1-year follow-up, the patient exhibited significant improvement in visual function and resolution of orbital swelling. Conclusion: This case highlights the critical role of surgical intervention in managing ONSHs that threaten visual function and cause mass effects. The transcranial-modified orbitofrontal approach proved effective in providing optimal access for safe tumor resection and improving visual outcomes. Integrating advanced imaging techniques and intraoperative monitoring contributes significantly to enhancing prognosis in ONSH cases.
