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 Litsea glaucencens Kuth is an aromatic plant used for food seasoning food and in Mexican traditional medicine. Among, L. glaucencens leaves properties, it has proven antibacterial activity which can be used against opportunistic pathogens like Listeria monocytogenes, a foodborne bacteria that is the causal agent of listeriosis, a disease that can be fatal in susceptible individuals. The aim of this work was to investigate the antibacterial activity of L. glaucescens Kuth leaf extracts against L. monocytogenes and to identify its bioactive components. Material and Methods L. glaucences leaves were macerated with four solvents of different polarity (n-hexane, dichloromethane, ethyl acetate, and methanol). To determine the capacity to inhibit bacterial proliferation in vitro, agar diffusion and microdilution methods were used. Next, we determined the minimal bactericidal concentration (MBC). Finally, we determined the ratio of MBC/MIC. Metabolites present in the active methanolic extract from L. glaucescens Kuth (LgMeOH) were purified by normal-phase open column chromatography. The structure of the antibacterial metabolite was determined using nuclear magnetic resonance (1H, 13C, COSY, HSQC) and by comparison with known compounds. Results The LgMeOH extract was used to purify the compound responsible for the observed antimicrobial activity. This compound was identified as 5,7-dihydroxyflavanone (pinocembrin) by analysis of its spectroscopic data and comparison with those described. The MIC and MBC values obtained for pinocembrin were 0.68 mg/mL, and the ratio MBC/MIC for both LgMeOH and pinocembrin was one, which indicates bactericidal activity. Conclusion L. glaucences Kuth leaves and its metabolite pinocembrin can be used to treat listeriosis due the bactericidal activity against L. monocytogenes.

This study was conducted to determine the influence of Dalbergia palo-escrito hexane extract supplemented to rabbits on productive performance, blood biochemistry, haematology, carcase traits, meat characteristics and meatballs shelf-life. A hexane extract of D. palo-escrito was obtained from leaves of the tree. Average feed consumption daily gain, average daily weight gain, total weight gain and feed conversion ratio, length body, lumbar circumference, carcase traits, texture profile analysis, meat colour, antioxidant properties, water activity as well as shelf life of meatballs (Total viable bacterial counts, staphylococcus counts, enterobacteria counts, antioxidant activity, pH and water activity) were determined.

Pithecellobium dulce produces a fruit used in alternative medicine that could be utilized to feed rabbits. The objective of this study was to measure the effect of the P. dulce fruit on productive performance, carcass traits, meat characteristics, and meat product quality as well as shelf-life. Seventy-two California × English pot crossbreed rabbits (35 d age) were randomly distributed into two treatments: a control group without P. dulce and another group fed with 5% of P. dulce, and fattening for 28 d. Productive performance parameters, blood biochemistry and hematology, apparent digestibility, carcass traits, meat characteristics, and meat product shelf-life were measured. The results indicate inclusion of 5% P. dulce improves (p < 0.05) dry and organic matter digestibility and feed conversion rate, but some serum blood enzymes were increased (p < 0.05). The a* value, hardness, and pH decreased (p < 0.05) in the group fed with P. dulce. Antioxidant properties in the meatballs were different (p < 0.05), improving shelf-life and acceptance in sensory analysis. In conclusion, the use of 0.5% of P. dulce fruits to feed fattening rabbits can be used to improve the shelf-life of rabbit meat.

ABSTRACT The objective of this study was to evaluate the effects of ginger as an additive in the diet of fattening rabbits. Sixty weaned rabbits (35 days old) were randomly assigned to four groups (n = 15). Animals were fed ad libitum with a control diet or one of three experimental diets supplemented with 0.5, 1, and 2 g of ginger per 100 g of feed during 28 d. Weight gain in the final week of the experiment was significantly greater in rabbits fed ginger at 0.5 g/100 g of feed than in those fed ginger at 1 and 2 g/100 g of feed or the control diet. No significant differences in morphometric measurements were observed among the treatments, but higher values of live weight, carcass length, and carcass circumference were observed in rabbits treated with ginger than in those fed the control diet. Regarding carcass quality parameters involving the kidneys and empty gastrointestinal tract, we found that rabbits treated with ginger at 0.5 g/100 g of feed showed significant differences from those treated with ginger at 1 and 2 g/100 g of feed or the control diet. pH, water holding capacity, L*, and a* did not significantly differ among the treatments, although greater water holding capacity was observed in rabbits treated with ginger than in control rabbits. Parameter b* was significantly higher in rabbits fed ginger at 2 g/100 g of feed than in those fed at 0.5 and 1 g/100 g of feed and in the control. The results found suggest that ginger can be used as an additive in diets of fattening rabbits.

The objective of the present study was to determine the effect of the application of a nanoemulsion made of orange essential oil and Opuntia oligacantha extract on avocado quality during postharvest. The nanoemulsion was applied as a coating in whole fruits, and the following treatments were assessed: concentrated nanoemulsion (CN), 50% nanoemulsion (N50), 25% nanoemulsion (N25) and control (C). Weight loss, firmness, polyphenol oxidase (PPO) activity, total soluble solids, pH, external and internal colour, total phenols, total flavonoids, antioxidant activity by 2,2′-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and 2,2-diphenyl-1-picrylhydrazyl (DPPH), while the structural evaluation of the epicarp was assessed through histological cuts. Significant differences were found (p < 0.05) among the treatments in all the response variables. The best results were with the N50 and N25 treatments for firmness and weight loss, finding that the activity of the PPO was diminished, and a delay in the darkening was observed in the coated fruits. Furthermore, the nanoemulsion treatments maintained the total phenol and total flavonoid contents and potentiated antioxidant activity at 60 days. This histological study showed that the nanoemulsion has a delaying effect on the maturation of the epicarp. The results indicate that using this nanoemulsion as a coating is an effective alternative to improve the postharvest life of avocado.

Objective: To compare outcomes of critically ill patients transferred from another island compared to those patients with direct admission from Emergency Department to intensive care unit (ICU). Patients and Methods: Retrospective study of prospectively collected data during 8 years. The population studied was all critical adult patients transferred from another island to our hospital and those directly admitted from the Emergency Department. Variables were age, sex, clinical diagnosis (coronary, medical, surgical, or trauma), acute physiology and chronic health evaluation (APACHE) II score at admission, ICU days of stay, days of mechanical ventilation and ICU mortality. Results: During the period of study, 3,115 patients coming from Emergency Department (Group 1) were admitted to our ICU and 138 were transferred from another island (Group 2). No significant statistically differences were found between both groups neither age, sex, APACHE II, ICU days, days of mechanical ventilation, and mortality rate (17.5% versus 20.3%, P = 0.43). The multivariate analysis showed that age, APACHE II score, ICU days of stay, type of patient, and days of mechanical ventilation were independent variables associated with mortality. Conclusions: No differences were found in the global prognosis of the admitted patients transferred from another island compared to those who were admitted directly from the Emergency Department. There is no impact on mortality in transferring a patient in our study population. [ABSTRACT FROM AUTHOR]
