Abstract
This study evaluated and compared the micronutrient profile and sensory properties of Tom-Brown, a traditional Nigerian weaning cereal produced from a blend of maize, millet, soybeans, and groundnuts, using two processing methods: fermented and roasted (Sample A) and roasted only (Sample B). Micronutrient analysis revealed significant differences (p < .05) between the two samples. Sample A exhibited significantly higher levels of vitamin B9 (32.40 ± 0.01 µg), vitamin C (1.90 ± 0.01 mg), vitamin B6 (0.36 ± 0.01 mg), vitamin B2 (0.06 ± 0.01 mg), and vitamin K (0.22 ± 0.01 mg) than Sample B. Notably, the iron content of Sample A (9.13 ± 0.04 mg) closely approached the FAO/WHO-recommended range of 9.30–11.00 mg, while Sample B provided 8.31 ± 0.01 mg. Conversely, roasting in Sample B resulted in higher phosphorus (236.00 ± 1.41 mg) and magnesium (110.50 ± 0.71 mg). When compared with the Standards Organisation of Nigeria (SON) baseline for complementary foods, both samples demonstrated highly satisfactory mineral scores, particularly for phosphorus, magnesium, iron, and zinc, making “Tom-Brown” an excellent, cost-effective formulation for combating infant protein-energy and micronutrient malnutrition. Sensory evaluation indicated that the fermented sample (Sample A) had an enhanced, characteristic nutty aroma that was preferred in traditional weaning foods.Keywords: Complementary Food, Infants, Breast Feeding, Amino Acid, Formulation

This repository contains data supporting the techno-scientific and materials engineering analysis of Pre-Columbian Guayupe ceramics. The archaeological materials come from Cluster-89, an 8.7-hectare site on alluvial terraces in the Andean foothills, where excavations revealed domestic areas with lithic tools, ceramic fragments, and funerary urns. Radiocarbon dates from these contexts indicate a human occupation spanning 777 to 536 cal BP. The dataset provides comprehensive evidence of ancient ceramic technology and temper analysis, including radiocarbon dating records, Raman spectroscopy spectra, and the physical characteristics of four distinct Guayupe ceramic groups.
This dataset contains:
The "Supp_1 R Code" folder contains the R code for the statistical analyses and the raw data for those analyses.
The "Supp_2. Petrographic analysis" folder contains the initial petrographic analysis report (PDF) for the ceramic materials analyzed.
The "Supp_3. SEM-EDS" folder contains the observations made and images acquired for each sample, based on the initially determined ceramic types.
The folder named Supp_4 XRD contains the XRD spectra for each analyzed sample corresponding to each initially defined type.
The folder named "Supp_5. Raman" contains the files for the signal obtained with Raman for sample T916

AbstractOsteoporosis is a chronic metabolic bone disorder associated with reduced bone mass, deterioration of bone microarchitecture and increased fracture risk. Bone health depends on the balance between bone formation by osteoblasts and bone resorption by osteoclasts. This study develops a deterministic mathematical model for osteoporosis progression by coupling normalised bone density with osteoblast and osteoclast activities and by incorporating nutritional and pharmacological controls. In response to the mathematical inconsistency identified in the original submission, the bone-density equation is reformulated to include homeostatic remodelling, while positive recruitment terms are introduced for the cellular compartments. The resulting equilibrium is explicitly derived and the complete Jacobian spectrum is obtained. Unlike the original formulation, the corrected system has three non-zero eigenvalues under the stated parameter restrictions, permitting a meaningful local asymptotic stability result. An optimal-control problem is then solved using Pontryagin's Maximum Principle, with adjoint equations, transversality conditions and bounded control characterisation. Numerical simulations are performed with Python using an adaptive Runge–Kutta method and a forward–backward sweep algorithm. The corrected results show that combined control maintains bone density substantially closer to its reference level while suppressing excess osteoclast activity. The revised formulation therefore provides a mathematically consistent framework for studying intervention strategies for osteoporosis progression.

У пациента с известной сосудистой аномалией мозга жалоба на головокружение требует разграничить два вопроса: где находится источник актуального синдрома и связана ли с ним структурная находка. Мальформация может вовлекать заднюю черепную ямку, но может быть и случайной находкой при ДППГ либо вестибулярной мигрени. Ошибка в сторону автоматического отнесения симптома к изображению задерживает диагностику периферического заболевания; обратная ошибка при остром стойком головокружении опасна пропуском сосудистого поражения [1,2,10].

En la región del Gran Caribe, el género Lobophora constituye un componente dominante en las comunidades algales asociadas a los arrecifes de coral. En el año 2023, durante el Bojeo a Cuba, se identificó la especie L. delicata adherida a sustratos rocosos de arrecifes de coral, en las localidades de Bahía Honda y Bahía de Vita. Para la identificación se analizaron los caracteres morfológicos diagnósticos de la especie y se compararon con las descripciones previas de Camacho et al. (2019) y Vieira et al. (2020a, b). Este nuevo reporte extiende la distribución de la especie a las Antillas Mayores.

A comparative analysis was conducted of the biochemical blood parameters observed in the rat kidney under the combined effects of "HCHF" diet-induced metabolic syndrome (MS) and various stressors (light desynchronosis and audiogenic stress). The study investigated how the combined impact of stress factors (light desynchronosis, audiogenic stress, MS, and their combination) leads to hormonal, metabolic, and renal function disorders in the organism.
