In this study, hybrid materials were synthesized incorporating curcumin, Cu2+ or Fe3+, and Kappa-carrageenan as a reducing agent to improve stability, considering that curcumin has low thermal solution which limits its applications. Colorimetric analysis showed color changes in the hybrids, ultraviolet–visible spectroscopy revealed band shifts infrared indicated wavenumbers, suggesting vibrational state of after bonding with metal ions. These techniques confirmed formation materials....
The irrational use of medications has increased the incidence microbial infections, which are a major threat to public health. Moreover, conventional therapeutic strategies starting become ineffective treat these infections. Hence, there is need develop and characterize novel antimicrobial compounds. Phytochemicals emerging as safe accessible alternative therapeutics for treating infectious diseases. Curcumin extracted from dried rhizome spice turmeric (Curcuma longa (Zingiberaceae))....
Fingerprints are unique for each individual contributing to human identification in forensic cases.Visualization of latent fingerprints usually involves the use a chemical substance that creates contrast between fingerprint residues and surface on which print was deposited.Commercial powders used as developers by papilloscopy have relatively high costs due their importation composition.The composite selected its suitable properties (adhesion texture) visualization digital, providing...
Fingerprints are unique to each individual, contributing human identification in forensic cases.The powder technique being widely used is considered one of the most important latent fingermarks analysis.In this sense, present work aimed synthesize 1-thiocarbamoyl-4,5dihydro-1H-pyrazoles and apply them as agents develop fingermarks.The compounds were prepared from an effective green synthesis via condensation chalcones with thiosemicarbazide ethanol under microwave irradiation.Pyrazoles...
The development of fingermarks is an important step in criminal cases.Latent require applications reagents to be developed before they can visualized.Different techniques enhance fingermarks' visualization have been employed and the powder dusting most common among them.The use food spices as latent developers could alternative method experiment chemistry teaching, considering that are low cost accessible.In this work, experimental methodology was applied undergraduate teaching for...
This study reports a route to obtaining novel and cost-effective rice husk-derived lignin/thiophene chalcone green composite for application in forensic science as fingermark developer through high energy milling. The material was properly characterized by UV-Vis, IR, fluorescence, X-ray diffraction scanning electron microscopy. product provided clear sharp images of latent fingermarks with minimal background staining, revealing all ridge details. Thus, the presented good performance...
REUSE OF ACETYLSALICYLIC ACID SYNTHESIZED IN ORGANIC CHEMISTRY LAB CLASSES AS A FINGERPRINT DEVELOPER: AN APPLICATION EDUCATION. Acetylsalicylic acid (ASA) synthesized in the practical classes of experimental organic chemistry is generally discarded after classes. Thus, objective this work to find an alternative application for ASA and promote awareness about recycling chemicals educational research environments. In addition, it explores subsequent creation powdered developers latent...
In this study, hybrid materials were synthesized incorporating curcumin, Cu²⁺ or Fe³⁺, and Kappa-carrageenan as a reducing agent to improve its stability, considering that curcumin has low thermal solution which limits applications. Colorimetric analysis showed color changes in the hybrids, ultraviolet-visible spectroscopy revealed band shifts infrared indicated wavenumbers, suggesting vibrational state of after bonding with metal ions. These techniques confirmed formation materials....
Tuberculosis (TB) dactylitis of the hand is a rare and challenging pathology, requiring positive bacterial identification through culture or biopsy for diagnosis. Treatment also challenging, although it typically yields an excellent response to long-term tuberculostatic therapy. We describe case osteoarticular tuberculous in 36-year-old woman with rheumatoid arthritis (RA) history lymphoma. The suspicion arose from insidious, painless swelling proximal interphalangeal joint second digit...
Background: Capsule panendoscopy is increasingly used in Crohn's disease (CD), particularly patients with extensive small bowel and colonic involvement. It offers a non-invasive, 1-step evaluation of both segments, making it appealing for monitoring treatment response. However, there need validated scoring systems that objectively assess inflammatory activity the colon. The aim this study was to externally validate Eliakim Score (Elk-S), developed mucosal inflammation CD by capsule...
The use of anabolic androgenic steroids is largely restricted worldwide since they are associated with innumerous side effects and health damage.However, apprehensions formulations agents have been extensively increasing throughout the world, making their analysis a common task in forensic field.In this sense, set three experiments was developed applied to undergraduate students Forensic Chemistry dealing visual inspection apprehended as well chemical identification by Infrared Spectroscopy...
THE CHEMISTRY OF NATURAL PRODUCTS APPLIED TO LATENT FINGERMARK DEVELOPERS. Natural formulations have attracted great interest of many researchers regarding their use as latent fingermark developers powders due important characteristics the presence natural pigments in these materials that offer a good contrast on applied surface and also luminescent properties, which facilitates visualization minutiae problematic substrates such multicolored surfaces. In addition, present low toxicity, are...
CLASSIC HYDRAZONES AS FINGERMARK DEVELOPERS: AN EXPERIMENTAL ORGANIC CHEMISTRY PROPOSAL. Fingermark dusting powders are an important tool of forensic practitioners, being a first-choice process for most crime scene investigators. The development new products is utmost importance science. Hydrazones comprise compounds derived from ketones or aldehydes in reaction with hydrazines. These reactions widely studied organic chemistry because the versatility these synthesis. study leads to...
