RESUMO
This work studied the effects of C. longa extract as a dietary supplement for Macrobrachium rosenbergii. Shrimp juvenile (n = 960, initial average weight 0.06 ± 0.042 g and initial stocking density 0.4 animals/L) received diets with different concentrations of turmeric extract (0.05, 0.2, 1%) for 60 days, and zootechnical (weight gain, specific growth rate, initial and final condition factor) and metabolic (activities of digestive enzymes, amino acid metabolism enzymes, and energy metabolism enzymes) parameters were evaluated. A transport simulation (TS) test was conducted and, in challenged animals, survival and antioxidant status were studied. Phenolic compound content and in vitro antioxidant potential of the turmeric extract were evaluated. Turmeric extract (0.05%) significantly increased weight gain and the activity of digestive enzymes. An increase in citrate synthase activity for all concentrations of turmeric was also observed. The glutamate dehydrogenase activity in the 0.05% group was also increased by turmeric extract. The in vitro antioxidant activity of the turmeric extract was like butylated hydroxytoluene (BHT), a common antioxidant, and the total phenolic content was 0.98 ± 0.02 mmolAG/g. In animals from the TS test, turmeric extract promoted a dose-dependent increase in animal survival. Furthermore, turmeric supplementation increased the activity of the enzymes catalase, glutathione reductase, glutathione peroxidase, glutathione S-transferase, and it reduced glutathione (GSH) content. A reduction in the levels of lipid peroxidation (TBARS) and protein carbonyl was also observed in the hepatopancreas of all experimental groups. The addition of low concentrations of turmeric extract to the diet of M. rosenbergii juvenile presents great potential for application in commercial shrimp farming, since the extract (at concentrations as low as 0.05 to 1%) increased weight gain and improved the physiological and metabolic conditions of the animals, improving the use of nutrients and consequently the animals' responses to stressful conditions, such as transport.

Salinity limits the growth and productivity of crops, to reverse these effects, natural pigments with antioxidant bioactivity can be studied, such as turmeric (Curcuma longa L.) and paprika (Capsicum annum L.). Therefore, it aimed to evaluate turmeric and paprika as possible saline stress attenuators and biostimulants during germination and initial development of smooth lettuce seedlings. In the laboratory, the seeds were treated for 1 hour with a solution of paprika and turmeric at doses 0 (negative control), 1, 2, 3 and 4 g L-1, and placed on a substrate with saline solution of sodium chloride 4 g L-1 (-0,4 Mpa), and a positive control, composed of dry seeds arranged in a substrate moistened with distilled water. Physiological quality analysis were carried out, and for the dose that showed the best result (4 g L-1), the treated seeds were grown in a greenhouse, and received weekly applications via foliar with a 4 g L-1 solution for turmeric and paprika. After the crop cycle, morphometric analyzes were performed. The turmeric and paprika solutions were analyzed by High-Performance Liquid Chromatography (HPLC) to identify the presence of bioactive substances. The turmeric doses were not efficient in overcoming the effects of salinity on seeds and seedlings, which was attributed to the low solubility of turmeric in water. Paprika, although it did not provide the biostimulant effect, was efficient in attenuating the effects of excess salt, at a concentration of 4 g L-1, promoting increases in physiological quality. In HPLC, a very low signal response was noted in relation to samples composed of turmeric and paprika solutions, indicating a low percentage of soluble compounds, which compromises bioactivity, and leads to the need for further analyses using surfactants and/or other solvents with which there is greater affinity.

PURPOSE: This randomized clinical trial aimed to compare the effects of a mucoadhesive formula, containing curcuminoids from Curcuma longa L. and glycerinated extract of Bidens pilosa L. (FITOPROT), associated with photobiomodulation (PBM), and of PBM exclusively, on the incidence of oral mucositis (OM)-induced by radiotherapy (RT) in the head and neck region, and the salivary expression of inflammatory cytokines, in patients with head neck cancer. METHODS: Patients were randomly assigned into two intervention groups-FITOPROT + PBM (n = 25) or PBM (n = 27). PBM protocol comprised a wavelength of 660 nm, 25 mW, 0.25 J/point, and daily irradiation from the first until the last day of RT. FITOPROT was gargled twice a day. All patients underwent a preventive oral care program throughout the study. OM degree, salivary concentration of nitrite, and inflammatory (IL-1, TNFα, IL-6, IL-8, and IL-12p70), and anti-inflammatory (IL-10) cytokines were assessed at baseline, and at the 7th, 14th, 21st, and 30th RT sessions. RESULTS: There were no differences in the OM degree between groups, but the RT dose significantly affected the OM. The RT significantly affected the salivary nitrite, TNFα, IL-1ß, and IL-10 concentrations. CONCLUSION: FITOPROT associated with PBM showed limited effects on preventing the incidence of severe OM compared to PBM alone. However, FITOPROT + PBM may be associated with nitrite and cytokine balance, which may contribute to the occurrence of fewer cases of severe OM.

This study aimed to examine whether dietary supplementation of broiler chickens with turmeric essential could mitigate the effects of cyclic heat stress conditions. Intestinal and immunological parameters and gene expression were evaluated during the grower phase. A total of 320 21-day-old male Cobb 500 broilers were distributed according to a completely randomized design with a 4 (diet) × 2 (environment) factorial arrangement and eight replications of five birds each. Dietary treatments consisted of a basal diet without essential oil (EO, negative control) and three diets containing low (100 mg kg-1), intermediate (200 mg kg-1), or high (300 mg kg-1) levels of turmeric EO. In the heat stress group, dietary supplementation with turmeric EO at 100 and 200 mg kg-1 improved body weight, feed conversion, breast yield, and relative liver weight. These supplementation levels reduced villus width, increased villus/crypt ratio, reduced the H/L ratio, and improved hepatic (HSP70 and SREBP1) and intestinal (OCLN) gene expression in birds under heat stress. These findings support the hypothesis that turmeric EO can be used to improve or restore intestinal integrity, modulate inflammation parameters, and, consequently, enhance the performance of broilers challenged by cyclic heat stress.

The therapeutic properties of turmeric essential oil have been extensively documented in both preclinical and clinical studies. Research indicates that its primary active compounds are promising candidates for addressing a wide range of pathologies, exhibiting anticancer, anti-inflammation, antioxidant, cardiovascular, hypoglycemic, dermatological, hepatoprotective, neurological, antiparasitic, antiviral, insecticidal, antifungal, and antivenom activities. While numerous compounds possess similar potential applications, the isolated active constituents of turmeric essential oil stand out due to their unique pharmacological profiles and absence of toxicity. This literature review meticulously compiles and analyzes the bioactivities of these constituents, emphasizing their molecular mechanisms of action, reported pharmacological effects, and potential therapeutic applications. The aim of this review is to provide a comprehensive synthesis of currently available clinical and preclinical findings related to individual turmeric essential oil compounds, while also identifying critical knowledge gaps. By summarizing these findings, this work encourages further research into the isolated compounds from turmeric oil as viable drug candidates, ultimately contributing to the development of innovative therapeutic strategies.

This study evaluated the effect of cobiotic (CO) composed of organic fructans powder of Agave tequilana and turmeric powder of Curcuma longa L. as an alternative of antibiotic growth promoters (AGPs) on growth performance, blood parameters, intestinal pH, oxidative stress, and cytokines serum levels of broiler chickens. A total of 135 one-day-old Ross 308 broilers distributed to five experimental groups, which included starter or finisher standard diets without AGPs (CON), CON + 0.25 COLI-ZIN g/kg feed (AGP), CON + 0.1 g Agave fructans/kg feed (AF), CON + 0.5 g turmeric powder/kg feed (TP) and CON + 0.1 g AF + 0.5 g TP /kg feed (CO), for 49 days. AF followed by TP, decreased feed intake, obtaining the best FCR. AGP increased the heterophil-lymphocyte ratio compared to other groups. CO significantly decreased the pH of the cecal content. AF increased IL-10 levels, while TP decreased it. AF decreased the IL-1ß levels. The present study showed that including a cobiotic based on AF and TP or components separately in a broilers diet improved growth performance, modified intestinal and cecum pH, and stimulated the immune system, which suggests CO as a safe alternative to AGP.

The prevalence of gingivitis is substantial within the general population, necessitating rigorous oral hygiene maintenance. OBJECTIVE: This study assessed a Garcinia indica (GI) fruit extract-based mouthrinse, comparing it to a 0.1% turmeric mouthrinse and a 0.2% Chlorhexidine (CHX) mouthrinse. The evaluation encompassed substantivity, staining potential, antimicrobial efficacy and cytocompatibility. METHODOLOGY: The study employed 182 tooth sections. For antimicrobial analysis, 64 extracted human teeth coated with a polymicrobial biofilm were divided into four groups, each receiving an experimental mouthrinse or serving as a control group with distilled water. Microbial reduction was assessed through colony forming units (CFU). Substantivity was evaluated on 54 human tooth sections using a UV spectrophotometer, while staining potential was examined on 64 tooth sections. Cytocompatibility was tested using colorimetric assay to determine non-toxic levels of 0.2% GI fruit extract, 0.1% Turmeric, and 0.2% CHX. RESULTS: Data were analysed with one-way ANOVA (α=0.05). Cell viability was highly significant (p<0.001) in the 0.2% GI group (64.1±0.29) compared to 0.1% Turmeric (40.2±0.34) and 0.2% CHX (10.95±1.40). For antimicrobial activity, both 0.2% GI (20.18±4.81) and 0.2% CHX (28.22±5.41) exhibited no significant difference (P>0.05) at end of 12 hours. However, 0.1% Turmeric showed minimal CFU reduction (P<0.001). Substantivity results at 360 minutes indicated statistically significant higher mean release rate in 0.1%Turmeric (12.47±5.84 ) when compared to 0.2% GI (5.02±3.04) and 0.2% CHX (4.13±2.25) (p<0.001). The overall discoloration changes (∆E) were more prominent in the 0.2% CHX group (18.65±8.3) compared to 0.2% GI (7.61±2.4) and 0.1% Turmeric (7.32±4.9) (P<0.001). CONCLUSION: This study supports 0.2% GI and 0.1% Turmeric mouth rinses as potential natural alternatives to chemical mouth rinses. These findings highlight viability of these natural supplements in oral healthcare.

COVID-19, caused by SARS-CoV-2, affects neuronal cells, causing several symptoms such as memory loss, anosmia and brain inflammation. Curcuminoids (Me08 e Me23) and curcumin (CUR) are derived from Curcuma Longa extract (EXT). Many therapeutic actions have been linked to these compounds, including antiviral action. Given the severe implications of COVID-19, especially within the central nervous system, our study aims to shed light on the therapeutic potential of curcuminoids against SARS-CoV-2 infection, particularly in neuronal cells. Here, we investigated the effects of CUR, EXT, Me08 and Me23 in human neuroblastoma SH-SY5Y. We observed that Me23 significantly decreased the expression of plasma membrane-associated transmembrane protease serine 2 (TMPRSS2) and TMPRSS11D, consequently mitigating the elevated ROS levels induced by SARS-CoV-2. Furthermore, Me23 exhibited antioxidative properties by increasing NRF2 gene expression and restoring NQO1 activity following SARS-CoV-2 infection. Both Me08 and Me23 effectively reduced SARS-CoV-2 replication in SH-SY5Y cells overexpressing ACE2 (SH-ACE2). Additionally, all of these compounds demonstrated the ability to decrease proinflammatory cytokines such as IL-6, TNF-α, and IL-17, while Me08 specifically reduced INF-γ levels. Our findings suggest that curcuminoid Me23 could serve as a potential agent for mitigating the impact of COVID-19, particularly within the context of central nervous system involvement.

We present a case of a 69-year-old man who presented for routine check-up and was incidentally found to have kidney failure with an initially unrevealing history and bland urinary sediment. He was diagnosed with oxalate nephropathy in the setting of chronic turmeric supplementation and chronic antibiotic therapy with associated diarrhea. Our case provides several key insights into oxalate nephropathy. First, the diagnosis requires a high index of clinical suspicion. It is uncommonly suspected clinically unless there is an obvious clue in the history such as Roux-en-Y gastric bypass or ethylene glycol poisoning. Diagnosis can be confirmed by histopathologic findings and corroborated by serum levels of oxalate and 24-hour urinary excretion. Second, the diagnosis can often be missed by the pathologist because of the characteristics of the crystals unless the renal pathologist has made it a rule to examine routinely all H&E sections under polarized light. This must be done on H&E, as the other stains dissolve the crystals. Third, one oxalate crystal in a routine needle biopsy is considered pathologic and potentially contributing to the AKI or to the CKD in an important way. Fourth, secondary oxalosis can be largely mitigated or prevented in many cases, especially iatrogenic cases. This can come through the surgeon or the gastroenterologist providing proper instructions to patients on an oxalate-restricted diet or other specific dietary measures. Lastly, this case highlights the success that results from cooperation and communication between the pathologist and the treating physician.

Active packaging made from biodegradable polymers and natural additives appears as an ecological alternative. In addition to having antioxidant activity and enhancing food preservation, it allows mitigating the negative impacts caused by improper disposal. This study pursued to produce biodegradable films based on a polymer blend PBAT/PLA (Ecovio®) using the flat extrusion method. The films were prepared with the incorporation of 5 wt% of powdered turmeric or cinnamon as natural additives. The films obtained, and those reprocessed twice, were characterized in terms of colorimetric, UV light transmittance, water contact angle, water vapor permeability, morphology, mechanical properties, and antioxidant activity. Cinnamon reduced the UV light transmittance and made a surface more hydrophobic. Reprocessing led to greater elongation and maximum load, associated with increased dispersion and distribution, as evidenced in the morphological analysis. The films developed have significant potential for applications in active food packaging, with emphasis on cinnamon-additivated films.

Natural irrigants, specifically when used with children are important as they have fewer adverse effects. Objectives: To evaluate the antibacterial effect and smear layer removal ability of sage versus turmeric irrigants. Methods: 60 roots of primary teeth were inoculated with E. faecalis and randomly allocated to the following subgroups (12 roots each): Subgroup (I): 0.2% sage solution, Subgroup (II): 12.5% turmeric solution, Subgroup (III): 2% chlorhexidine solution, Subgroup (IV): contaminated only, Subgroup (V): negative controls. Microbiological culturing was performed. Assessment of the smear layer removal ability, 40 roots (10 roots in each group) were randomly divided; Subgroup 1: 0.2% Sage solution. Subgroup 2: 12.5% turmeric solution. Subgroup 3: 2% chlorohexidine. Subgroup 4: saline. The evaluation of smear layer removal was performed by SEM. Results: Chlorohexidine showed the highest percentage reduction in bacterial count followed by turmeric, then the sage group. A comparison of the smear layer removal, scores showed significant differences in the middle section of the different groups, with the turmeric group having a significantly higher median score than the sage group. Conclusion: chlorohexidine showed the highest antibacterial properties and smear layer removal ability followed by turmeric then sage

We report on a systematic review of the efficacy of turmeric derivatives for the in vivo treatment of peripheral neuropathies. Our review protocol followed the PRISMA Statement. The Medline (PubMed), Web of Science, Scopus, and Scielo databases were used. The search strategy was ("neuropathy" OR "neuropathies" OR "nerve injury" OR "nerve injuries") AND ("curcumin" OR "turmeric yellow" OR "yellow, turmeric" OR "diferuloylmethane"). Eligibility criteria were in vivo animal models, published in English, Portuguese, Spanish, or French, evaluating the efficacy of turmeric derivatives in the treatment of peripheral neuropathies. We have included 30 papers, and all consisted of pre-clinical trials with good methodological quality. Animals treated with turmeric derivatives (i.e., curcumin, curcumin by-products and curcumin loaded delivery systems) demonstrated remarkable amelioration in the injuries caused by diabetic and sciatic neuropathy, as well as for vincristine, cisplatin, and alcohol-induced neuropathy, especially with regards to the functional recovery of the affected nerve. Turmeric has great potential for the treatment of peripheral neuropathies, including those associated with diabetes mellitus. Clinical trials still need to be performed to assess the feasibility of human treatment as an alternative or adjuvant to existing pharmacological therapy.

In the present study, chitosan and chitosan/turmeric-based membranes were produced, characterized and applied in in vivo experiments showing the applicability for skin wound repair. Chitosan 1 % (w/v), chitosan + glycerol 30 % (w/w) and chitosan + glycerol 30 % + turmeric 1.5 % (w/w) membranes were produced through the casting technique. Self-sustainable, homogeneous, and flexible membranes were obtained from all materials tested. The FTIR spectra showed the main vibrational bands for materials used in the chemical groups. The membranes containing glycerol are more flexible than those formed with pure chitosan. Membranes formed with glycerol and glycerol/turmeric are more hydrophilic compared to the membranes formed by pure chitosan. The in vivo results showed that the group who received the chi/gly/turmeric membrane had a statistically greater reduction in the injured area, as well as a better healing process in the histological analysis compared to the other experimental groups. The material developed here is from a natural source, low cost and easy to apply and can accelerate the process of repairing skin lesions.

Curcumin, the primary polyphenol found in turmeric, is derived from the Curcuma longa plant. Since curcumin is nontoxic and has a wide range of medicinal qualities, including anti-oxidant, analgesic, anti-inflammatory, and antibacterial action, it has been widely employed in Ayurveda medicine for ages. Curcumin has recently been discovered to have anti-cancer properties through its impact on numerous biological pathways involved in carcinogenesis, metastasis, tumorigenesis, cell cycle regulation, mutagenesis, and oncogene expression. In this study, we determined the Antiproliferative activity and apoptosis-inducing mechanism of C. longa (Turmimax®) on human cancer cells. The cytotoxic effect was evaluated against HeLa cell lines using the MTT (3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide) assay. Flow cytometric analysis was performed to detect apoptotic cell death. Turmimax® exhibits promising properties as a potential anti-cancer therapeutic agent in human cervical adenocarcinomas and possibly other cancer types, with an IC50 value of 87.89 µg/mL. In HeLa cells treated with Turmimax®, cell cycle arrest was seen in the G0/G1 and S phases. By inducing apoptosis and increasing the number of apoptotic cells in a dose-dependent manner, the experimental data suggest that Turmimax® has considerable promise in cancer prevention and treatment.

PURPOSE: To assess the effect of a mucoadhesive herbal medicine containing curcuminoids and a glycerinated extract of Bidens pilosa L. (FITOPROT) in association with photobiomodulation (PBM) therapy and a Preventive Oral Care Program (POCP) compared to PBM and POCP in the treatment of radiotherapy (RT)-induced oral mucositis (ROM) and in the quality of life of these patients. METHODS: A double-blind clinical trial was performed with head and neck cancer patients undergoing RT or chemoradiotherapy. Participants were randomized into two groups: Group 1 (n=27): PBM and POCP; and Group 2 (n=25): PBM, POCP and FITOPROT. The PBM protocol was daily irradiation, 660 nm, 25mW, 0.25 J/point from the first until the last day of RT. The FITOPROT was used as mouthwash twice a day. ROM was evaluated based on the scales of the World Health Organization and National Cancer Institute. The quality of life was evaluated using the University of Washington Questionnaire, OHIP-14 and Patient-Reported Oral Mucositis Symptom Scale. The MMAS-8 questionnaire was used to evaluated the adherence to POCP and FITOPROT. Data were collected at baseline, 7th, 14th, 21st, and 30th RT sessions. RESULTS: No statistical differences were found between the groups for the ROM evaluation. Both groups experienced worsening of the quality of life during the RT. No statistically significant differences between groups were observed for any of the instruments evaluated. CONCLUSION: The results suggest that PBM associated with FITOPROT and POCP control the severity of ROM and stabilize the QoL of patients with head and neck cancer.

Dyslipidemia is common in patients with chronic kidney disease. Curcumin, a bioactive polyphenol from Curcuma longa, can improve lipid profile. This study aims to analyze the effects of Curcuma Longa extract supplementation on lipid profile and lipoprotein subfractions in hemodialysis (HD) patients. This is a longitudinal, double-blind, washout-period randomized clinical trial. The patients were randomized into two groups: the curcumin group (n = 10) (orange and carrot juice with 2.5 g of Curcuma Longa extract) and the control group (n = 11) (juice without curcumin) 3x/w during HD sessions for 3 months. After the washout period, patients continued the supplementation as a crossover for the same period. The lipid profile was measured using enzymatic assays. The high-density lipoprotein and low-density lipoprotein subfractions analyses were performed using LipoprintTM. In the curcumin group, the triglyceride values tended to decrease with a different triglyceride variation between the pre and post-intervention for the control and curcumin groups of 38.5 (19.8) mg/dL (p = 0.06). There was no statistical difference in the others parameters. In conclusion, Curcuma longa extract may be a good nutritional strategy to reduce triglyceride plasma levels in hemodialysis patients, but it seems ineffective for the other parameter.

A cúrcuma longa é amplamente conhecida por seu uso culinário e na estética. A curcumina, um antioxidante da cúrcuma, possui propriedades que impactam diretamente na regeneração da pele e na cicatrização de feridas. Neste sentido, este estudo tem como objetivo geral apresentar a cúrcuma longa e seus benefícios quanto ao consumo oral nos tratamentos dermatológicos. Para desenvolvimento deste estudo, optou-se pelo método de revisão bibliográfica. A ingestão de cúrcuma longa, precisa ser amplamente estudada e divulgada, uma vez que seus benefícios vêm de sua composição, principalmente da curcumina. Não se deve ignorar que sua ingestão provoca resultados e efeitos extremamente melhores do que seu uso tópico, e quanto mais próximo do natural, longe da industrialização, mais concentrado será o produto. Por fim, a presente pesquisa não esgota o tema em questão, por isso, sugere-se a realização de um novo estudo, onde seja avaliado as diferenças de resultados e bene

The use of active packaging to reduce food waste has been a very effective alternative. An eminent concern is the use of plastic materials of petroleum origin and toxic additives in the processing of these packages. Thus, the focus on the use of biodegradable and natural raw materials that minimize waste generation and promote greater consumer safety has been preferable. The objective of the research was to investigate the effects of turmeric essential oil (TEO) on corn starch and pectin extract films manufactured by solution casting method. The antioxidant and antimicrobial potential of the oil was confirmed by the tests: antimicrobial diffusion disk, determination of the content of phenolic compounds and antioxidant activity by the DPPH and FRAP method. The chromatographic analysis confirmed the presence of active chemical constituents such as Turmerone, Ar-Turmerone and ß-Turmerone. The results showed that the oil promoted a change in the color of the films, increased mechanical strength and reduced flexibility, keeping transparency, solubility, WVP and thermal stability unchanged. In the direct application test of the film as packaging for sliced bread, no visible contamination was detected during the nine weeks of analysis. Therefore, the active film with 3 % TEO was shown to be a viable solution for manufacturing biodegradable and safe active films that can be applied as food packaging.
