Physicochemical Rationale of Matrix Effects Involved in the Response of Hydrogel-Embedded Luminescent Metal Biosensors
Authors: Rotureau Elise , Pagnout Christophe , Duval Jérôme F. L. 
Published: November 2024

There is currently a critical need for understanding how the response and activity of whole-cell bacterial reporters positioned in a complex biological or environmental matrix are impacted by the physicochemical properties of their micro-environment. Accordingly, a comprehensive analysis of the bioluminescence response of Cd(II)-inducible PzntA-luxCDABE Escherichia coli biosensors embedded in silica-based hydrogels is reported to decipher how metal bioavailability, cell photoactivity and ensuing light bioproduction are impacted by the hydrogel environment and the associated matrix effects. The analysis includes the account of (i) Cd speciation and accumulation in the host hydrogels, in connection with their reactivity and electrostatic properties, and (ii) the reduced bioavailability of resources for the biosensors confined (deep) inside the hydrogels. The measurements of the bioluminescence response of the Cd(II) inducible-lux biosensors in both hydrogels and free-floating cell suspensions are completed by those of the constitutive rrnB P1-luxCDABE E. coli so as to probe cell metabolic activity in these two situations. The approach contributes to unraveling the connections between the electrostatic hydrogel charge, the nutrient/metal bioavailabilities and the resulting Cd-triggered bioluminescence output. Biosensors are hosted in hydrogels with thickness varying between 0 mm (the free-floating cell situation) and 1.6 mm, and are exposed to total Cd concentrations from 0 to 400 nM. The partitioning of bioavailable metals at the hydrogel/solution interface following intertwined metal speciation, diffusion and Boltzmann electrostatic accumulation is addressed by stripping chronopotentiometry. In turn, we detail how the bioluminescence maxima generated by the Cd-responsive cells under all tested Cd concentration and hydrogel thickness conditions collapse remarkably well on a single plot featuring the dependence of bioluminescence on free Cd concentration at the individual cell level. Overall, the construction of this master curve integrates the contributions of key and often overlooked processes that govern the bioavailability properties of metals in 3D matrices. Accordingly, the work opens perspectives for quantitative and mechanistic monitoring of metals by biosensors in environmental systems like biofilms or sediments.

O desflorestamento tem crescido em valor significativo, enquanto aumenta o consumo por produtos oriundos de recursos naturais. Esse crescimento impacta diretamente as florestas, pois os produtos oferecidos do mercado tem matéria-prima proveniente dos recursos naturais. Em Landri Sales, um dos fatores que reduz a cobertura vegetal é a atividade agrícola que tem se expandido na região. Desse modo, um dos mecanismos eficientes para monitorar esse comportamento é conduzida por meio do geoprocessamento. Com isso, este estudo buscou realizar uma análise comparativa da cobertura vegetal no município de Landri Sales–PI, entre os anos de 2022 e 2023. Para isso, foram utilizados arquivos shapes do perímetro do município retirado do site do IBGE. Após o download das cenas e dos arquivos SHP referente ao território do município, usou-se o software Qgis para o processamento de dados. Foi constatado que no ano de 2022 a área alterada foi de 26938,4126 ha, enquanto em 2023 a área alterada foi de 33356,6525 ha, tendo um leve aumento de 6418,24 ha. O fenômeno El Niño impacta a região Nordeste ao provocar uma seca mais intensa, resultando em uma redução significativa na quantidade de chuvas. Isso leva a uma diminuição drástica na disponibilidade de recursos hídricos, afetando diretamente a vegetação da região.

Authors: Anggraeni Ratih , Marbun Romauli Anna Teresia , Siagian Hartika Samgryce , Lubis Amelia Hasana 
Published: November 2024

The Body Mass Index (BMI) value is used to determine the body composition value, calculated using a formula involving height and weight. Increasing body weight will affect the size of the stomach circumference. One indicator of BMI that can identify the risk of morbidity due to increased body weight is the measurement of the size of the abdominal circumference. If there is an increase in BMI, the risk of developing hypertension and other heart diseases also increases. Hypertension is when a person's blood pressure exceeds normal (120/80mmHg). This research was conducted to analyze the influence of BMI and abdominal circumference on hypertension symptoms using analytical observation. Random sampling was taken from the USU Faculty of Medicine student population with the criteria of having a history of heart disease, a history of metabolic disease, taking heart medication, and being an athlete. Respondents had their height and weight measured, their BMI values were calculated, then their abdominal circumference, and their blood pressure. The results showed that there was an influence between BMI and abdominal circumference on symptoms of hypertension. There was a significant correlation between BMI and systole (p=0.000) and diastole (p=0.014) as well as a moderate correlation coefficient for systole (r=0.466) and diastole (r=0.340). There is a correlation between abdominal circumference and systole (p=0.000) and diastole (p=0.038) and a moderate level correlation coefficient with systole (r=0.480) and diastole (r=0.289). It can be concluded that there was an influence of BMI and LP on hypertension.

A crescente demanda por tratamentos odontológicos que aliam funcionalidade e estética tem impulsionado o desenvolvimento de técnicas de implante imediato após exodontia, especialmente em regiões de alta exigência estética. Esse método minimiza o tempo de tratamento e reduz o número de intervenções cirúrgicas, preservando de forma eficaz os tecidos ósseo e gengival, o que é fundamental para alcançar resultados estéticos satisfatórios. O objetivo deste estudo é apresentar um caso clínico em que a colocação de um implante dentário imediato, assistido por cirurgia guiada, foi realizada na região do dente 21, demonstrando os benefícios da técnica quanto à precisão e previsibilidade. A cirurgia guiada permitiu um planejamento tridimensional minucioso, garantindo uma instalação exata do implante e evitando danos desnecessários aos tecidos circundantes, o que contribuiu para uma cicatrização otimizada. Conclui-se que o uso de implante imediato, associado a enxertos e à tecnologia de cirurgia guiada, permite uma reabilitação mais previsível e eficaz, resultando em uma restauração estética e funcional superior. Esse caso reforça o valor da integração de tecnologias avançadas e técnicas minimamente invasivas na implantodontia, particularmente em regiões estéticas.

BACKGROUND
Nonalcoholic fatty liver disease (NAFLD) encompasses a variety of liver conditions impacting individuals who consume minimal or no alcohol. Recently, traditional Chinese medicine has been gradually used to treat mild to moderate fatty liver, among which Dendrobium nobile Lindl. powder has been affirmed by many doctors and patients to be effective. However, there is limited research on combining this treatment with standard therapies for mild to moderate NAFLD.
AIM
To survey the effect of combining Dendrobium nobile Lindl. powder with standard treatment on liver function and lipid metabolism disorder in patients with mild to moderate NAFLD.
METHODS
Eighty patients with mild to moderate NAFLD participated in this retrospective study, classified into two groups: The observation group (n = 40) and the control group (n = 40). In November 2020 and November 2022, the study was conducted at People’s Hospital of Chongqing Liang Jiang New Area. The control group received standard treatment, while the observation group received Dendrobium nobile Lindl. powder based on the control group. The study compared differences in traditional Chinese medicine clinical syndrome scores, liver fibrosis treatment, liver function indicators, lipid levels, and serum inflammatory factor levels before and after treatment, and we calculated the incidence of adverse reactions for both groups.
RESULTS
The total effective rate was 97.50% in the observation group and 72.5% in the control group. After 8 weeks of treatment, the main and secondary symptom scores remarkably decreased, especially in the observation group (P < 0.05), and there was a significant reduction in the serum levels of hyaluronic acid (HA), laminin (LN), human rocollagen III (PC III), and collagen type IV (CIV). The levels of HA, LN, PC III, and CIV were significantly lower in the observation group (P < 0.05). After 8 weeks, both groups indicated remarkable improvements in liver function and blood lipid levels, with the observation group having even lower levels (P < 0.05). Serum levels of interleukin-1β, tumor necrosis factor-α, and interleukin-8 also dropped significantly. The observation group had a lower rate of adverse reactions (5.00%) compared to the control group (22.50%).
CONCLUSION
Adding Dendrobium nobile Lindl. powder to standard treatment has been found to remarkably improve symptoms and reduce inflammation in patients with mild to moderate fatty liver disease. It also enhances hepatic function and lipid profile, ameliorates liver fibrosis indices, and lowers the risk of side effects. Consequently, this therapeutic protocol shows promise for clinical implementation and dissemination.
