Quantitative determination of selected heavy metals and micronutrients in branded dairy products sold in Nigeria using atomic absorption spectroscopy (AAS)

Quantitative analysis of heavy metals and nutrients in food helps indicate the safety and quality of food for final consumers. The present study was conducted to assess the presence of heavy metals (arsenic, copper, mercury, chromium, and lead) and the nutritional value of calcium in branded milk and yogurt to evaluate health risks for consumers. Ten (10) samples of branded milk and dairy products manufactured in Nigeria were purchased. The metal contents of the samples were determined using atomic absorption spectroscopy. The concentrations of calcium in the milk samples were between 9.33 ± 0.0023 and 18 ± 0.0071 ppm and were detected in all samples. Arsenic concentrations ranged from 0.45 ± 0.00042 to 2.48 ± 0.00064 ppm in eight branded samples but were undetected in two samples. Chromium levels were undetected in most samples, except for two with concentrations of 0.12±0.00049 ppm and 0.23±0.00021 ppm, respectively. Copper ranged from 0.032±0.00021 ppm to 0.129±0.00021 ppm in six samples. Mercury levels were detected in six samples at a concentration of 1.0±1.0 ppm. Lead concentrations ranged from 0.15±0.00064 to 0.29±0.00028 ppm in three samples. The study found heavy metals above the ideal concentration in branded milk and dairy products in Nigeria, highlighting the need for quality control measures during production to prevent contamination.

Effect of Dioscorea villosa extract and the phytoestrogen diosgenin on ovariectomized mice with zymosan-induced arthritis

Abstract Humans are exposed to natural compounds such as phytoestrogens primarily through diet and supplements. These compounds promote health by alleviating the symptoms and illnesses associated with menopause and arthritis. Diosgenin (DSG) occurs naturally in plants such as Dioscorea villosa (DV) and binds to estrogen receptors, so it may have similar effects to this hormone, including against arthritis. Thus, we investigated the effect of chronic treatment with dry extract of DV and its phytoestrogen DSG on ovariectomized mice with arthritis. We found that dry extract of Dioscorea villosa (DV) contains the phytoestrogen diosgenin (DSG) in its composition. Furthermore, arthritic mice treated with DV and DSG showed reduced neutrophil accumulation in the articular cartilage. Also, the dry extract of DV administered orally (v.o) did not alter the leukocyte count in the joints or promote changes in the reproductive tract. However, DSG altered these parameters, with possible beneficial effects by reducing symptoms related to reproductive aging. Thus, oral treatment with dry extract of DV and subcutaneous (s.c) treatment with DSG showed promise by acting against inflammation caused by arthritis and reducing symptoms in the reproductive tract due to menopause.

Stability study of umbilical cord mesenchymal stem cells formulation in large-scale production / 药学学报

Umbilical cord mesenchymal stem cells (UC-MSCs) have been widely used in regenerative medicine, but there is limited research on the stability of UC-MSCs formulation during production. This study aims to assess the stability of the cell stock solution and intermediate product throughout the production process, as well as the final product following reconstitution, in order to offer guidance for the manufacturing process and serve as a reference for formulation reconstitution methods. Three batches of cell formulation were produced and stored under low temperature (2-8 ℃) and room temperature (20-26 ℃) during cell stock solution and intermediate product stages. The storage time intervals for cell stock solution were 0, 2, 4, and 6 h, while for intermediate products, the intervals were 0, 1, 2, and 3 h. The evaluation items included visual inspection, viable cell concentration, cell viability, cell surface markers, lymphocyte proliferation inhibition rate, and sterility. Additionally, dilution and culture stability studies were performed after reconstitution of the cell product. The reconstitution diluents included 0.9% sodium chloride injection, 0.9% sodium chloride injection + 1% human serum albumin, and 0.9% sodium chloride injection + 2% human serum albumin, with dilution ratios of 10-fold and 40-fold. The storage time intervals after dilution were 0, 1, 2, 3, and 4 h. The reconstitution culture media included DMEM medium, DMEM + 2% platelet lysate, 0.9% sodium chloride injection, and 0.9% sodium chloride injection + 1% human serum albumin, and the culture duration was 24 h. The evaluation items were viable cell concentration and cell viability. The results showed that the cell stock solution remained stable for up to 6 h under both low temperature (2-8 ℃) and room temperature (20-26 ℃) conditions, while the intermediate product remained stable for up to 3 h under the same conditions. After formulation reconstitution, using sodium chloride injection diluted with 1% or 2% human serum albumin maintained a viability of over 80% within 4 h. It was observed that different dilution factors had an impact on cell viability. After formulation reconstitution, cultivation in medium with 2% platelet lysate resulted in a cell viability of over 80% after 24 h. In conclusion, the stability of cell stock solution within 6 h and intermediate product within 3 h meets the requirements. The addition of 1% or 2% human serum albumin in the reconstitution diluent can better protect the post-reconstitution cell viability.

An econometric study of the number of undernourished people in Colombia from 2000 to 2021

The importance of food (in)security has been one of the United Nations Sustainable Development's main goals. Over 828 million people worldwide cannot acquire enough food to meet the minimum daily dietary energy requirements (undernourished). Therefore, the present study examines the factors that affect the number of undernourished people in Colombia by assessing macroeconomic data for the period 2000-2021 including gross domestic product (GDP) per capita, unemployment, and inflation rates. A quantitative, empirical, correlation design was used to examine and describe the relationship among the variables. The findings showed that the proposed variables presented the correct signs, were statistically significant, and were in line with the economic theory Thus, the study concluded that although income shocks brought on by inflation and unemployment undoubtedly impact household food (in)security, other factors must also be considered for policy and practice to effectively reduce food insecurity for households.

La importancia de la (in)seguridad alimentaria ha sido uno de los principales objetivos del Desarrollo Sostenible de las Naciones Unidas y más de 820 millones de personas en el mundo no pueden adquirir suficientes alimentos para satisfacer los requerimientos mínimos diarios de energía dietética (subalimentadas). Por lo tanto, el presente estudio examina los factores que afectan el número de personas subalimentadas en Colombia mediante la evaluación de datos macroeconómicos para el período 2000-2021, incluido el producto interno bruto (PIB) per cápita, el desempleo y las tasas de inflación. Se utilizó un diseño cuantitativo, empírico y correlacional, para examinar y describir la relación entre las variables. Los hallazgos mostraron que las variables propuestas presentaron los signos correctos, fueron estadísticamente significativas y de acuerdo con el propuesto por la teoría económica. Por lo tanto, el estudio concluyó que, si bien los impactos en los ingresos causados por la inflación y el desempleo indudablemente afectan la inseguridad alimentaria de los hogares, también es importante considerar otros factores en los esfuerzos de políticas y prácticas para mitigar la inseguridad alimentaria de los hogares.

A importância da (in)segurança alimentar tem sido um dos principais objetivos do Desenvolvimento Sustentável das Nações Unidas e mais de 820 milhões de pessoas no mundo não podem adquirir alimentos suficientes para atender às necessidades energéticas diárias mínimas (subalimentadas). Por tanto o presente estudo examina os fatores que afetam o número de pessoas subalimentadas na Colômbia, avaliando dados macroeconômicos para o período 2000-2021, incluindo produto interno bruto (PIB) per capita, desemprego e taxas de inflação. Um desenho quantitativo, empírico e de correlação foi usado para examinar e descrever a relação entre as variáveis. Os achados mostraram que as variáveis propostas apresentaram os sinais corretos, foram estatisticamente significativas e em consonância com a teoria econômica. Assim, o estudo concluiu que, embora os choques de renda causados pela inflação e pelo desemprego indubitavelmente afetem a insegurança alimentar das famílias, outros fatores também são importantes a serem considerados nos esforços de políticas e práticas para mitigar a insegurança alimentar das famílias.

Calidad microbiológica de embutidos crudos: estudio del caso en Latinoamérica / Microbiology of raw sausages: a case of study in Latin America

Introducción. Los embutidos crudos se componen de carne fragmentada y otros ingredientes no cárnicos (sal, especias, fosfatos, nitritos) pero cuya formulación varía según el país; son productos altamente perecederos y podrían representar un riesgo para el consumidor. Objetivo. Los embutidos frescos son de alto consumo en varios países de Latinoamérica, por ello, el objetivo de esta revisión bibliográfica es compilar la información disponible sobre la calidad microbiológica de este tipo de productos en la región. Materiales y métodos. Se realizó una búsqueda de literatura (desde el 2006 a la fecha) en las principales bases de datos. Resultados. Se determinó que la calidad microbiológica de los embutidos crudos latinoamericanos no es adecuada según la reglamentación. Las bacterias más estudiadas son los microorganismos totales aerobios mesófilos (MTAM), y las bacterias ácido-lácticas (BAL); estos dos grupos son los referentes para determinar la vida útil. Los patógenos más analizados son Salmonella spp. y Listeria monocytogenes y llama la atención que Staphyloccoccus aureus no se utiliza como indicador de malas prácticas de higiene o de inocuidad. Conclusiones. En general se confirma que los embutidos frescos podrían ser un riesgo para la salud pública ya que presentan recuentos microbiológicos altos, en ocasiones no regulados. Algunos agentes antimicrobianos como los compuestos etanólicos de propóleos (EEP), compuestos fenólicos y bacteriófagos han sido estudiados. Sin embargo, no está claro si a nivel artesanal este tipo de ingredientes son utilizados del todo. Finalmente, destaca la necesidad de armonizar las metodologías de estudio y la normativa vigente en los distintos países(AU)

Introduction. Raw sausages are products composed of comminuted meat and other non- meat ingredients (salt, spices, phosphates, nitrites) but the formulation varies in each country. Given this nature, raw sausages are highly perishable and may represent an important risk for consumers. Aim. As raw sausages are highly consumed in many Latin-American countries, the objective of this literature review was to compile the available information about studies of the microbial quality of these products in the region. Materials and methods. For that purpose, a literature search was performed on main data bases to compile studies from 2006 to nowadays. Results. In general, it was found that microbiological quality of Latin-American raw sausages is not adequate according to current regulation. Total aerobic mesophilic microorganisms (TAMM) and Lactic Acid Bacteria (LAB) were the most studied indicators; these two groups are the main reference to establish shelf life. Salmonella spp. and Listeria monocytogenes were the most studied pathogens, and it is noticeable that Staphyloccoccus aureus is not used as an indicator for safety or manipulation. Conclusions. It is perceived that raw sausages in the region could represent a public health risk as they frequently present high microbiological counts, not regulated in many cases. For conservation, antimicrobial agents as propolic ethanoplic extracts (PEE), phenolyc compounds, and bacteriophages have been studied. However, it is not clear if these ingredients are used at the artisanal level, even though it can be assumed that they are not given the high microbial numbers that are reported. Finally, it stands out the need of harmonization of methodologies and current regulation in the countries(AU)

Relación entre biometría fetal, producto de acumulación de los lípidos y condición trófica al nacer / Relationship between fetal biometry, lipid accumulation product and the trophic condition at birth

Fundamento: Las alteraciones del estado nutricional materno generalmente se relacionan con desviaciones del crecimiento fetal, que pueden detectarse por los parámetros biofísicos fetales e identifican la posible condición trófica al nacer. Objetivo: Determinar la posible relación entre los parámetros biométricos fetales, la condición trófica al nacer y el producto de acumulación de los lípidos. Metodología: Se realizó un estudio transversal en el Policlínico Chiqui Gómez Lubian del municipio Santa Clara, durante el año 2019, en una población de 253 gestantes normopeso supuestamente sanas al inicio de la gestación. La muestra no probabilística fue de 144 gestantes. Las variables de estudio fueron: producto de acumulación de los lípidos, biometría fetal y condición trófica al nacer. Se utilizaron métodos teóricos, empíricos y estadísticos. Resultados: En el segundo trimestre ningún parámetro biométrico coincidió con la condición al nacer de pequeño, mientras que para el grande coincidieron las circunferencias cefálica y abdominal. En el tercer trimestre la longitud del fémur y la circunferencia abdominal coinciden en la identificación del pequeño y del grande. El PAL se correlacionó con la circunferencia abdominal del tercer trimestre y con el peso al nacer; presentando mayor frecuencia de valores en el tercer tertil para los nacimientos grandes. Conclusiones: La circunferencia abdominal fue el parámetro biométrico con mayor coincidencia con la condición trófica al nacer, la que se asoció con valores en el tercer tertil del PAL para la detección de nacimientos grandes, relacionándose el fenotipo normopeso metabólicamente obeso con el crecimiento fetal por exceso.

Background: Maternal nutritional status disorders are usually related to fetal growth deviations, which can be detected by fetal biophysical parameters and identify the possible trophic condition at birth. Objective: To determine the possible relationship between fetal biometric parameters, the birth trophic state and lipid accumulation product. Methodology: A cross-sectional study was conducted at the Chiqui Gómez Lubian Polyclinic in Santa Clara municipality, during 2019, in a population of 253 normal-weight pregnant women who were apparently healthy at the beginning of their gestation. The non-probability sample was made up of 144 pregnant women. Study variables were: lipid accumulation product, fetal biometry and trophic condition at birth. Theoretical, empirical and statistical methods were used. Results: In the second trimester, none of the biometric parameters matched the condition at birth as a small child, while in the large one the head and abdominal circumferences matched. In the third trimester, femoral length and abdominal circumference coincide in identifying the small one and the large one. LAP correlated with third trimester abdominal circumference and birth weight, presenting higher frequency of values in the third tertile for large births. Conclusions: Abdominal circumference was the biometric parameter with the highest coincidence with trophic condition at birth, associated with values in the third tertile of the LAP for detecting large births, relating the metabolically obese normal weight phenotype with excessive fetal growth.

IMPACT OF LEADER'S INVOLVEMENT IN AGILE MATURITY ASSESSMENTS

Agile is the way we look at things happening around us. Agile is a behavior pattern, how you look at the world's complex situations, how you react to situations, how you visualize a solution, how you reach the solution. You can either think of a complex problem or a situation and worry about it or you break that into meaningful small chinks & try to solve it. Agile adds that fun element of tackling smaller challenges systematically. As we move from the traditional hierarchical working to self-managing and agility, it is evident for teams to see the radical shift in people's day-to-day behaviors. These new ways of working bring in an increased sense of ownership, proactive, open communication, accepting failures, and more importantly trust and transparency among team members. Agile maturity assessments are tools or processes used to evaluate and measure an organization's or team's level of agility and their effectiveness in implementing Agile principles and practices. These assessments help identify areas of strength and improvement, enabling organizations to enhance their Agile adoption and transformation journey

Oxidative stress and antioxidant markers in patients with alopecia areata: A comparative cross-sectional study

Background: Alopecia areata is a chronic inflammatory skin disease. Oxidative stress may contribute to the pathogenesis of this condition. Aim: To evaluate the serum oxidative stress markers and antioxidant capacity in patients with alopecia areata. Methods: This cross-sectional study was performed on 40 patients with alopecia areata and 40 healthy controls. The fasting blood sugar, C-reactive protein, lipid profile, and serum oxidative markers, including advanced glycation end products and advanced oxidation protein products, were measured in this study. Also, antioxidant enzymes, including paraoxonase-1, lecithin-cholesterol acyltransferase and serum ferric-reducing antioxidant power, were determined. Results: The serum levels of advanced glycation end products and advanced oxidation protein products were significantly higher in patients with alopecia areata, compared to the controls (P < 0.001), whereas the levels of ferric-reducing antioxidant power, paraoxonase-1 and lecithin-cholesterol acyltransferase were significantly lower in patients with alopecia areata, compared to the controls (P < 0.001). The mean fasting blood sugar level was significantly higher in patients with alopecia areata, compared to the controls. The ferric reducing antioxidant power level was significantly associated with the percentage of hair loss (P = 0.01, r = 0.4) and the serum C-reactive protein level (P = 0.03, r = –0.3) in patients with alopecia areata. Limitations: Since the current study had a cross-sectional design, no cause-effect relationship was established between alopecia areata and oxidative stress. The sample size of our study was also small. Conclusion: Based on the present results, the oxidant-antioxidant enzymatic system is impaired in alopecia areata due to the increased oxidative products and decreased antioxidant activity

Target product profiles for diagnosis of sepsis: Proposing a new approach for diagnostic innovation

Background & objectives: Sepsis, including neonatal sepsis, remains a prevalent cause of morbidity and mortality in low- and middle-income countries such as India, representing 85 per cent of all sepsis-related deaths globally. Early diagnosis and timely initiation of treatment is challenging due to non-specific clinical manifestations and non-availability of rapid diagnostic tests. There is an urgent need for affordable diagnostics with fast turnaround time catering to the needs of end-users. Target product profiles (TPPs) have been found instrumental in developing ‘fit-for-use’ diagnostics, thus reducing the time taken to facilitate development and improving diagnosis. Hitherto, no such guidance or criteria has been defined for rapid diagnostics for sepsis/neonatal sepsis. We propose an innovative approach for developing the diagnostics for sepsis screening and diagnosis which can be utilized by diagnostic developers in the country. Methods: Three-round Delphi method, including two online surveys and one virtual consultation, was adopted to define criteria for minimum and optimum attributes of TPPs and build consensus on characteristics. Expert panel (n=23) included infectious disease physicians, public health specialists, clinical microbiologists, virologists, researchers/scientists and technology experts/innovators. Results: We present a three-component product profile for sepsis diagnosis, (i) screening with high sensitivity, (ii) detection of aetiological agent, and (iii) profiling of antimicrobial susceptibility/resistance, in adults and neonates with an option of testing different considerations. An agreement of >75 per cent was achieved for all TPP characteristics by Delphi. These TPPs are tailored to the Indian healthcare settings and can also be extrapolated to other resource-constraint and high-disease burden settings.

La formulación seleccionada fue F1 (13,6 g/100 g p.s. proteína y 13,1 g/100 g p.s. fibra cruda). La digestibilidad de la proteína fue del 69 %, el cual es cercano a valores reportados para algunos componentes de la BC. La capacidad de hinchamiento y retención de agua fue 2,55 ml/g; 12,74 %, respectivamente. El crecimiento de L. brevis en medio MRS modificado con BC no presentó diferencias estadísticas con el medio control, indicando el potencial prebiótico presente en la BC. La barra de cereal tuvo un 39% de actividad inhibitoria de ECA-I, demostrando la acción de los compuestos bioactivos posiblemente liberados durante la digestión de la BC. Conclusión. La formulación desarrollada presenta propiedades funcionales importantes y podría generar beneficios para la salud(AU)

Introduction. Cereal bars (CB) are marketed as a healthy snack; however, their nutritional quality is low. An alternative to improve this is the incorporation of ingredients such as soybean sprouts, which have a higher protein content than some seeds; as well as fruit by-products that contain important bioactive compounds. Objective. To evaluate the nutritional content and techno-functional properties of a cereal bar formulated from pseudocereals, soybean sprouts, and fruit processing by-products. Materials and Methods. 6 formulations (F0-F5) were developed. The content of protein and crude fiber was determined, the formulation that presented the highest content of these components was selected. The in-vitro digestibility of the protein, the technofunctional properties, potential prebiotic and inhibitory activity of ACE-I were determined for the selected BC. Results. The selected formulation was F1 (13.6g/100g p.s. protein and 13.1g/100 g p.s. crude fiber). Protein digestibility was 69%, which is close to reported values for some CB components. The swelling and water retention capacity was 2.55 ml/g; 12.74%, respectively. The growth of L. brevis in modified MRS medium with CB did not present statistical differences with the control medium, indicating the prebiotic potential present in CB. The cereal bar had 39% ACE-I inhibitory activity, demonstrating the action of bioactive compounds possibly released during CB digestion. Conclusion. The developed formulation has important functional properties and could generate health benefits(AU)

Characterization of fillets of Amazon and real hybrid sorubins / Caracterización de filetes de sorubinas híbridas amazónica y real

Background: Many fish hybrids (i.e., obtained by crossing two species) are produced rather than pure species because of their better growth rate and/or acceptance of formulated feed. However, few studies evaluate and compare their meats and acceptance, including, e.g., for the Amazon hybrid sorubim (Pseudoplatystoma reticulatum x Leiarius marmoratus) and the real hybrid sorubim (Pseudoplatystoma corruscans x L. marmoratus). Objective: Thus, this work aimed to evaluate the physical, chemical, microbiological, and sensory characteristics of fillets from the Amazon and real hybrid sorubins. Method:Proximate composition, instrumental color, water holding capacity, cooking losses, and shear force were measured.Microbiological analyses of the fillets were carried out for Salmonellasp. and Staphylococcusaureus to ensure food safety during sensory analysis. Results: Fillets presented excellent quality, classified in category A (lipids below 5% and proteins between 15 and 20%). There was no significant difference (p>0.05) between the evaluated fillets for several parameters: the average water holding capacities were 33.72 and 34.67%, the cooking losses were 14.93 and 13.41%, the shear forces were 2.21 and 1.74 kgf, and the luminosities were 49.61 and 45.04 for the fillets of Amazonian hybrid sorubim and real hybrid sorubim, respectively. Discussion: There was an evident relationship between water-holding capacities and shear forces. Amazonian hybrid sorubim fillets presented lower intensity of red. However, there was no sensory difference between the hybrids, and both had an acceptance rate above 80%. Conclusion: The hybridization does not alter the characteristics of the fish fillets

Antecedentes: Muchos híbridos de peces (i.e., obtenidos al cruzar dos especies) se producen en lugar de especies puras debido a su mejor tasa de crecimiento y/o aceptación de alimentos formulados. Sin embargo, pocos estudios evalúan y comparan sus carnes y aceptación, incluyendo, p. ej., para lo surubí híbrido amazónico (Pseudoplatystoma reticulatum x Leiarius marmoratus) y lo surubí híbrido real (Pseudoplatystoma corruscans x L. marmoratus). Objetivo: Así, el objetivo de este trabajo fue evaluar las características físicas, químicas, microbiológicas y sensoriales de filetes sorubines híbridos amazónico y real. Método: Se midió composición proximal, color instrumental, capacidad de retención de agua, pierdas por cocción y fuerza de corte. Se realizaron análisis microbiológicos de los filetes para Salmonella sp. y Staphylococcus aureus para garantizar la seguridad alimentaria durante el análisis sensorial. Resultados: Los filetes presentaron una excelente calidad, siendo clasificados en la categoría A (lípidos por debajo del 5% y proteínas entre 15 y 20%). No hubo diferencia significativa (p>0.05) entre los filetes evaluados para varios parámetros: las capacidades de retención de agua fueron 33.72 y 34.67%, las pierdas por cocción fueron 14.93 y 13.41%, las fuerzas de corte fueron 2.21 y 1.74 kgf y las luminosidades fueron 49.61 y 45.04 para los filetes de sorubim híbrido amazónico y sorubim híbrido real, respectivamente. Discusión: Hubo una relación evidente entre las capacidades de retención de agua y las fuerzas de corte. Los filetes de sorubim híbridos amazónicos presentaron menor intensidad de rojo. Sin embargo, no hubo diferencia sensorial entre los híbridos, y ambos tuvieron una tasa de aceptación superior al 80%. Conclusión: La hibridación no altera las características de los filetes de pescado
