To estimate the economic and financial viability of a pig farm in central sub-tropical Mexico within a 5-year planning horizon, a Monte Carlo simulation model was utilized. Net returns were projected ...using simulated values for the distribution of input and product processes, establishing 2021 as base scenario. A stochastic modelling approach was employed to determine the economic and financial outlook. The findings reveal a panorama of economic and financial viability. Net income increased by 555%, return on assets rose from 3.36% in 2022 to 11.34% in 2026, and the probability of decapitalization dropped from 58% to 13%, respectively in the aforesaid periods. Similarly, the probability of obtaining negative net income decreased from 40% in 2022 to 18% in 2026. The technological, productive, and economic management of the production unit allowed for a favorable scenario within the planning horizon. There is a growing interest in predicting the economic sectors worth investing in and supporting, considering their economic and development performance. This research offers both methodological and scientific evidence to demonstrate the feasibility of establishing a planning schedule and validating the suitability of the pork sector for public investment and support.

The myofibroma is defined as a benign neoplasm formed by myoid contractile cells localized around the wall of thin blood vessels, it is a tumor that presents itself mostly in infancy although it may ...occur at any age and it is most common in head and neck; it is uncommon to be localized in the oral cavity and even less common if it is intraosseous. It may also be associated to miofibromatosis or present itself as a solitary lesion. The differential diagnosis depends on the localization and the radiographic characteristics; it would be very difficult to include, at first hand, myofibroma as an intraosseous lesion. Histopathologically, a neoplasm with a biphasic pattern formed by spindle cells in fascicles and bundles, spindle nucleus with eosinophilic cytoplasm inside a hyalinized stroma was found. In lesions of neoplasms of spindle cells histological studies should be supported by an immunohistochemical panel and show positive results to antibodies Actin, smooth muscle Actin and Vimentin.

Report
BACKGROUNDSarcomas of the head and neck region are rare tumors, constituting less than 1% of malignant neoplasms in this area, of which few cases (20%) originate from bone or cartilage. ...Chondrosarcoma is a malignant neoplasm that develops in bone, with a predilection for the pelvis, chest wall, and scapula, and is uncommon in the maxilla and jaw. Although this type of lesion has locally aggressive behavior, destroying the affected bone, it can metastasize when it is not diagnosed early and compromise the patient's life. CASE SUMMARYOn intraoral examination of a 32-year-old female with a tumor in the middle third of the face, a well-defined rise in volume of approximately 3 cm in diameter was observed. Computed tomography with 3-dimensional reconstruction was performed, and we observed that the osteolytic lesion affected the vestibular cortex as the palatal bone. Hematoxylin and eosin staining revealed an appearance that was similar to mature hyaline cartilage, hypercellularity, nuclear and cellular pleomorphism, and multinucleated cells, with significant vacuolization. CONCLUSIONDetermination of the clinical and histopathological characteristics of rare neoplasms in the maxillofacial region, such as chondrosarcomas, allows the pathologist and surgeon to make the appropriate therapeutic decisions, optimizing the patient's prognosis.
Mexico is an extensively diverse country with a wide variety of wild species of blackberries (
Rubus
spp.), which are rich in bioactive compounds, however, these fruits are underutilized. ...Fermentation is a process that transforms the chemical compounds of fruits and increases nutraceutical properties. This study aimed to determine the physicochemical changes and the bioactive compounds profile that take place during the fermentation of wild blackberries using yeast EC 1118 and to evaluate its relationship with antioxidant activity (AOx). The results indicated that after 96 h of fermentation the content of carbohydrates (56%), total phenolic compounds (37%), and anthocyanins (22%), decreased, respectively. The physicochemical parameters showed statistic differences (
p
≤ 0.05) at the endpoint of fermentation. The diversity of fatty acids was increased (55%), compared with unfermented blackberries. The modification of carbohydrates, anthocyanins, catechin, gallic and ellagic acid profiles were also monitored performing chromatographic techniques. The AOx, determined by ORAC and DPPH assays, showed the highest results for ORAC at 96 h increased a 140.2%, while DPPH values enhanced a 36.6% at 48 h of bioprocessing. Strong positive correlations were found between fermentation time and DPPH values (
r
= 0.8131), between ORAC and gallic acid content (
r
= 0.8688), and between anthocyanin content and pH (
r
= 0.9126). The fermentation of wild blackberries with EC 1118 yeast represents an alternative for development and formulation of potential ingredients for functional foods.
Chickpea hydrolysates could have antihypertensive potential, but there are no evaluations in vivo. Thus, the antihypertensive potential of a chickpea protein hydrolysate obtained before and after ...extrusion (a process that modifies protein digestibility) was evaluated. Protein precipitates were obtained from extruded and unextruded chickpea flours by isoelectric precipitation and hydrolyzed (α-amylase/pepsin/pancreatin). Chemical composition was determined (standard methods). ACE-I inhibition assays were carried out using a colorimetric test. For antihypertensive effect evaluations, spontaneously hypertensive rats (n = 8) received the treatments intragastrically (extruded or unextruded hydrolysate (1.2 g/kg), captopril (25 mg/kg), or water only). Fat, ash, and carbohydrate contents were lower in extruded chickpea flour (p < 0.05 versus unextruded). The protein content varied between protein precipitates (91.03%/78.66% unextruded/extruded (dry basis)) (p < 0.05). The hydrolysates’ IC50 values (mg/mL) were 0.2834 (unextruded)/0.3218 (extruded) (p > 0.05). All treatments lowered the blood pressure (p < 0.05 vs. water). The extruded hydrolysate showed a more potent antihypertensive effect than the unextruded one (p < 0.05), an effect similar to captopril (p > 0.05). The results suggest that protein extrusion can be used to generate protein hydrolysates with improved health benefits. The findings have implications for the design and production of functional foods that could help to prevent hypertension or serve as an adjunct in its treatment.
The objective of this research was to analyze the adoption behavior over time for the improved variety of garlic CEZAC 06, and the factors associated with the adoption process through survival ...analysis (SA), in North-Central Mexico. The data comes at farm level and was collected in 2019 through a questionnaire given to 40 garlic farmers in Zacatecas, Mexico. The results show that 62.5 % of the farmers who adopted CEZAC 06 carried out this process in the first two years after they were first introduced to it. The factors that played a role in the adoption process were: farmer age, how long the farmer had been in business for, number of hectares availables for garlic production, yield, number of college-educated family members, income from crop farming, income from garlic farming, agriculture-related courses taken, financial aid from the federal government, and being part of any type of organization. Improving yield and the quality of the garlic bulb requires an adequate extension system that allows farmers to receive updated and reliable information on the importance of technological innovation. Highlights • The analysis also suggested that new technologies should be transmitted at higher rates to increase adoption. This can be done by implementing courses aimed at farmers with low educational backgrounds, small plots of land and low productivity levels. • The factors affecting the adoption process were: farmer age, how long the farmer had been in business, yield, etc. • CEZAC 06 will increase yield and rural farmers could improve the quality of the bulb as a marketable surplus. • This work contributes to the scarce literature on the application of survival analysis to agricultural technologies.
Tannins are phenolics found in fruits such as wild
Rubus
berries. The aim of this study was to determine the profile by LC–ESI–MS/MS and NMR, antioxidant capacity (AOX) of the tannins in two Mexican ...wild blackberries. Fractions rich in tannins (FRT) were isolated using different solvents and chromatographic resins. The LC–ESI–MS/MS and NMR results showed that catechin and epicatechin (
