Type 2 diabetes mellitus(T2DM)is recognized as a serious public health concern with a considerable impact on human life,long-term health expenditures,and substantial health losses.In this context,the use of dietary polyphenols to prevent and manage T2DM is widely documented.These dietary compounds exert their beneficial effects through several actions,including the protection of pancreatic islet β-cell,the antioxidant capacities of these molecules,their effects on insulin secretion and actions,the regulation of intestinal microbiota,and their contribution to ameliorate diabetic complications,particularly those of vascular origin.In the present review,we intend to highlight these multifaceted actions and the molecular mechanisms by which these plant-derived secondary metabolites exert their beneficial effects on type 2 diabetes patients.

Background:Evidence on the health benefits of occupational physical activity(OPA)is inconclusive.We examined the associations of baseline OPA and OPA changes with all-cause,cardiovascular disease(CVD),and cancer mortality and survival times.Methods:This study included prospective and longitudinal data from the MJ Cohort,comprising adults over 18 years recruited in 1998-2016,349,248 adults(177,314 women)with baseline OPA,of whom 105,715(52,503 women)had 2 OPA measures at 6.3±4.2 years(mean±SD)apart.Exposures were baseline OPA,OPA changes,and baseline leisure-time physical activity.Results:Over a mean mortality follow-up of 16.2±5.5 years for men and 16.4±5.4 years for women,11,696 deaths(2033 of CVD and 4631 of cancer causes)in men and 8980 deaths(1475 of CVD and 3689 of cancer causes)in women occurred.Combined moderately heavy/heavy baseline OPA was beneficially associated with all-cause mortality in men(multivariable-adjusted hazard ratio(HR)=0.93,95%confidence interval(95%CI):0.89-0.98 compared to light OPA)and women(HR=0.86,95%CI:0.79-0.93).Over a mean mortality follow-up of 12.5±4.6 years for men and 12.6±4.6 years for women,OPA decreases in men were detrimentally associated(HR=1.16,95%CI:1.01-1.33)with all-cause mortality,while OPA increases in women were beneficially(HR=0.83,95%CI:0.70-0.97)associated with the same outcome.Baseline or changes in OPA showed no associations with CVD or cancer mortality.Conclusion:Higher baseline OPA was beneficially associated with all-cause mortality risk in both men and women.Our longitudinal OPA analyses partly confirmed the prospective findings,with some discordance between sex groups.

Undoubtedly, since its appearance, the interest and use of autologous fat transfer (AFT) as a breast reconstruction technique have been increasing, becoming one of the main surgical alternatives for aesthetic breast augmentation. This increase in its popularity has led to the development of new technologies to increase its efficacy and safety, however, it has inherently implied the inadequate use of this procedure, mainly when performed by unqualified medical personnel. We present the case of a patient with complications following a breast AFT for aesthetic purposes, performed by a general practitioner without a specialty in plastic and reconstructive surgery.

Parkinsonism by unilateral,intranigralβ-sitosterolβ-D-glucoside administration in rats is distinguished in that theα-synuclein insult begins unilaterally but spreads bilaterally and increases in severity over time,thus replicating several clinical features of Parkinson’s disease,a typicalα-synucleinopathy.As Nurr1 repressesα-synuclein,we evaluated whether unilateral transfected of rNurr1-V5 transgene via neurotensin-polyplex to the substantia nigra on day 30 after unilateralβ-sitosterolβ-D-glucoside lesion could affect bilateral neuropathology and sensorimotor deficits on day 30 post-transfection.This study found that rNurr1-V5 expression but not that of the green fluorescent protein(the negative control)reducedβ-sitosterolβ-D-glucoside-induced neuropathology.Accordingly,a bilateral increase in tyrosine hydroxylase-positive cells and arborization occurred in the substantia nigra and increased tyrosine hydroxylase-positive ramifications in the striatum.In addition,tyrosine hydroxylase-positive cells displayed less senescence markerβ-galactosidase and more neuron-cytoskeleton markerβIII-tubulin and brain-derived neurotrophic factor.A significant decrease in activated microglia(positive to ionized calcium-binding adaptor molecule 1)and neurotoxic astrocytes(positive to glial fibrillary acidic protein and complement component 3)and increased neurotrophic astrocytes(positive to glial fibrillary acidic protein and S100 calcium-binding protein A10)also occurred in the substantia nigra.These effects followed the bilateral reduction inα-synuclein aggregates in the nigrostriatal system,improving sensorimotor behavior.Our results show that unilateral rNurr1-V5 transgene expression in nigral dopaminergic neurons mitigates bilateral neurodegeneration(senescence and loss of neuron-cytoskeleton and tyrosine hydroxylase-positive cells),neuroinflammation(activated microglia,neurotoxic astrocytes),α-synuclein aggregation,and sensorimotor deficits.Increased neurotrophic astrocytes and brain-derived neurotrophic factor can mediate t

Low income is the main problem of millions of farmers who are cultivating 4.81 million hectares in the Philippines. This problem is attributed to challenges specifically low yield, low quality of produce, and significant post-harvest losses, particularly in a resource-scarce setting. This study aimed to help increase the farmers’ income in selected towns of Nueva Ecija through the promotion and use of special purpose rice production technology. Twenty (20) farmer-cooperators in three towns of Nueva Ecija were selected to demonstrate the production technology covering a total area of 4.75 hectares during the dry season, and 3.3 hectares during the wet season, both in 2023. Extension modalities such as training, techno-demo establishment, information material and technical assistance provision, and market linkage were undertaken to enhance their knowledge, attitude, and skills on special rice production and enterprise. The study utilized the descriptive quantitative method wherein the data were gathered through surveys, specifically personal interviews. Results showed that 70% of the farmer-cooperators were male and 60% were living below the poverty threshold. The farmers were 53 years old on average and engaged in farming as their primary source of income. The average yield of special purpose rice particularly the CLS-2 variety was higher (6.46 MT/ha and 6.22 MT/ha during dry and wet seasons, respectively) than that of inbred or non-special rice. The income per hectare from special purpose rice production per hectare was Php 75,420.00, which is higher than that of regular rice at Php 29,389.00, giving a higher benefit of Php 46,031.00. The technology adopters and area planted increased (from 6 to 9 and from 1.4 hectares to 2.75 hectares, respectively) in Licab, Nueva Ecija. The opposite was true in Sto. Domingo and Guimba, Nueva Ecija where farmers were discouraged by the marketing issues that arose.

为促进优质天然富硒植物资源的科学开发利用，本文选取富硒金花葵为研究对象，重点研究了其不同器官中硒的分布、含有机硒活性成分提取条件和抗氧化性，并探讨了植物源有机硒活性成分的药用价值和经济价值。采用氢化物发生-原子荧光光谱法(Hydride Generation-Atomic Fluorescence Spectrometry， HG-AFS)检测样品中的硒含量，采用超声波辅助乙醇提取金花葵花朵中的含硒有机活性组分并使用响应面法优化提取工艺，同时对含硒提取物开展抗氧化物活性研究。结果显示，金花葵各器官中硒含量从高到低依次为叶、果、花、根和茎，分别为21.99 mg/kg、14.29 mg/kg、12.93 mg/kg、10.90 mg/kg和10.23 mg/kg。响应面优化结果表明，含硒有机活性成分最佳提取参数为提取温度40 ℃、固液比1：60、提取时间40 min、超声功率350 W、乙醇浓度50%(V/V)和提取次数1次。在最佳提取参数下，硒的提取率为35.65%±0.65%。DPPH抗氧化活性测试显示，含硒有机活性成分的半抑制浓度(IC50)为0.048 mg/mL(硒元素浓度为0.79 μg/mL)，羟基自由基清除实验显示样品浓度为8 mg/mL时达到最大清除率97%，半抑制浓度为0.56 mg/mL，还原力实验表明样品的还原能力随样品浓度的增大而增强。证明金花葵的含硒乙醇提取物具有良好的抗氧化能力。本研究可以为合理利用富硒金花葵和研发加工富硒农副作物提供一些理论依据。

The plant vacuole plays a fundamental role in cell homeostasis.The successful application of patch-clamp tech-nique on isolated vacuoles allows the determination of the functional characteristics of tonoplast ion channels and transporters.The parallel use of a sensor-based fluorescence approach capable of detecting changes in calcium and proton concentrations opens up new possibilities for investigation.In excised patch,the presence of fura-2 in the vacuolar solution reveals the direct permeation of calcium in plant TPC channels.In whole-vacuole,the activity of non-electrogenic NHX potassium proton antiporters can be measured by using the proton sensitive dye BCECF loaded in the vacuolar lumen by the patch pipette.Both vacuolar NHXs and CLCa(chloride/nitrate antiporter)are inhibited by the phosphoinositide PI(3,5)P2,suggesting a coordinated role of these proteins in salt accumulation.Increased knowledge in the molecular mechanisms of vacuolar ion channels and transporters has the potential to improve our understanding on how plants cope with a rapidly changing environment.
