Transmission electron microscopy observations (40,000×) showed that valproic acid liposomes have a spherical molecular shape and a particle size of below 250 nm. The ex vivo and in vivo results showed that liposomal formulations provided enhanced brain exposure. Among the formulations studied, Formula 4 (F4) showed greater uptake of valproic acid into the brain than plasma. The high brain targeting efficiency index for F4 indicated the preferential transport of the drug to the brain. The study demonstrated the successful formulation of surface-modified valproic acid liposomes for nasal delivery with brain targeting potential.In spite of the persistent efforts by the responsible state institutions to eradicate galamsey operations in Ghana, little attention is given to the inhabitants' characteristics that may affect the surge in illegal mining operations. This study was designed to investigate whether local community dwellers' socio-demographic characteristics affect their participation in galamsey activities-an aspect that has not been independently investigated in the scientific literature. Cross-sectional survey quantitative data were sourced using 342 semi-structured household questionnaires. The results showed that the majority (69.3%) of the local dwellers engaged in galamsey operations. The binary logistic regression model showed that socio-demographic variables such as age, marital status, religious status and educational status of the respondents significantly determined their participation in illegal mining activities. The study, therefore, concludes that local dwellers' socio-demographic characteristics significantly influence their participation in artisanal and small-scale mining (ASM) operations and contribute to the surge in illegal mining activities in Ghana. The study recommends that the Government of Ghana and related stakeholders should focus on creating more youth jobs of significant prospects in local communities. In addition, investing in education and promoting the agenda of higher educational attainment in rural areas is a forward-looking step to reducing the growing illegal mining activities in the country.Single-driver molecular events specific to the metabolic colorectal cancer (CRC) have not been clearly elucidated. Herein, we identified 12 functional miRNAs linked to activated metabolism by integrating multi-omics features in metabolic CRC. These miRNAs exhibited significantly enriched CRC driver miRNAs, significant impacts on CRC cell growth and significantly correlated metabolites. Importantly, miR-20a is minimally expressed in normal colorectal tissues but highly expressed in metabolic CRC, suggesting the potential therapeutic target. Bioinformatics analyses further revealed miR-20a as the most powerful determinant that regulates a cascade of dysregulated events, including Wnt signaling pathway, core enzymes involved in FA metabolism program and triacylglycerol abundances. In vitro assays demonstrated that elevated miR-20a up-regulated FA synthesis enzymes via Wnt/β-catenin signaling, and finally promoted proliferative and migration of metabolic CRC cells. Selleck HSP27 inhibitor J2 Overall, our study revealed that miR-20a promoted progression of metabolic CRC by regulating FA metabolism and served as a potential target for preventing tumor metastasis.Knowledge of soil nutrient status is a basic requirement in sustainable agriculture. However, assessment of soil properties has long been done through conventional laboratory analysis, which is costly and time-consuming. Therefore, developing alternative, cheaper and faster techniques for soil analysis is highly required. Mid-infrared spectroscopy (MIRS) techniques are rapid, convenient, environmentally friendly, and nondestructive techniques for quantifying several soil properties. This study aimed to evaluate the prediction performance of MIR for pH, organic carbon (O.C.), available phosphorus and sulfur, total nitrogen, exchangeable cations, and micronutrient. Soil samples were collected from southern Ethiopia. In this study, properties of 3882 soil samples were used as references from different parts of Ethiopia. Partial least squares regression (PLSR) was used for calibration. The correlation of measured and predicted properties of soil samples collected was analyzed using the Pearson correlation coefficient. Better prediction was obtained for Ca (R2 = 0.95 and RPD = 3.9), CEC (R2 = 0.92 and RPD = 3.5), TN (R2 = 0.92 and RPD = 3.4), OC (R2 = 0.91 and RPD = 3.4), Mg (R2 = 0.84 and RPD = 2.6), pH (R2 = 0.85 and RPD = 2.4) and Fe (R2 = 0.65 and RPD = 1.7). In general, soil properties could be predicted using MIRS methods. On the other hand, soil nutrients that showed poor prediction require further studies.Malnutrition remains one of the major human health issues affecting millions of people in sub-Saharan Africa (SSA). Hence, the objective of this study was to quantify the nutritional and phytochemical compositions of immature pods of pigeonpea genotypes to select promising lines with unique nutritional quality for production and cultivar development. Seven preliminarily tested and identified pigeonpea genotypes were grown under field conditions using a randomized complete block design with three replicates to quantify the nutritional and phytochemical contents in the immature pods. Significant (P ≤ 0.01) genotype effect was detected for the assessed nutritional and phytochemical compositions. Relatively higher contents of iron (15.53 mg/100g), zinc (1.59 mg/100g), magnesium (114.60 mg/100g) and total flavonoid (8.47 mg CE/g) were present in genotype Ilonga_14m1 ICEAP-0054. Higher compositions of beta-carotene (2.84 mg/100g), total phenolics (20.42 mg GAE/g), and vitamin-C (95.84 mg/100g) were detected in genoor direct production with promising nutrient profiles for food and nutrition security.The inefficiencies and uncertainties surrounding solutions from existing inversion methods have necessitated investigation for more efficient techniques for the inversion of ill-posed magnetic problems. In this study, the Social Spider Optimization (SSO) algorithm has been modified, adopted and successfully used in modelling physical characteristics of magnetic anomalies originating from simple-shaped geologic structures. The study, aimed at testing the capacity and efficiency of the SSO algorithm to model magnetic data of varying complexity, was successfully conducted on both synthetic data with varying levels of noise and real field data obtained from mining fields in Senegal and Egypt. To assess the mathematical nature of the inverse problem considered, error energy maps were produced for each model parameter pairs in the synthetic examples. These maps enabled the pre-assessment of the resolvability model parameter for the ill-posed problem. In addition, uncertainty analysis aimed at providing insight to the reliability of the obtained solutions was carried out using the Metropolis-Hastings (M-H) sampling algorithm. Results show that the procedure converges fast and generates accurate results even when confronted with constrained multi-parameter non-linear inversion problems. Its outstanding converging speed and accuracy of the results reveal it as an excellent procedure for overcoming agelong problems of local optimal solutions associated with pre-existing algorithms. The consistency of the results with actual values affirms the efficacy of the new procedure which is pioneering in geophysical literature. It is therefore a stable and efficient tool for performing geophysical data inversion and is therefore recommended for use in inverting geophysical data with higher complexities like seismic reflection and gravity data, that require many corrections to be performed before reliable geological interpretations can be made.

Since the 90s'

infection has expanded the geographical area and central-eastern European countries had seen first alveolar echinococcosis (AE) human cases. AE is considered to be a very rare disease in Europe with average incidences of 0.03-0.2/100,000 inhabitants/year. Because of a suitable orography, this study aims to confirm whether there are human AE cases in Armenia, identify areas at risk, and also estimate AE annual incidence.

Retrospective AE case finding was carried out at main multi-profile medical centers equipped with the modern diagnostic means. The medical records of all patients with liver surgery admitted between January 2008 and June 2020 were reviewed. A specific form was developed in EpiInfo v.7.2. Annual national incidence was estimated using population denominators provided by the National Institute of Statistics.

Overall, 11 AE cases have been identified. All patients were diagnosed at advanced stages, with subsequent poor prognosis and costly treatment. Confirmation was based on tissue biopsy and medical imaging results. Age ranged from 12 to 58years with a median of 33yrs. Patients were from rural communities, mostly in the Gegharkunik region (6 cases, 55%). Annual average incidence of AE was 0.033/100,000 varying between 0.032 in 2008 and 0.1 in 2017.

There are human AE cases happening in Armenia since more a decade ago. In the absence of an AE surveillance system, the burden of AE disease is difficult to estimate. Development of national AE guidelines with a case definition should help enforcing registry of all cases, early diagnosis and also clinical and public awareness.

Radiation therapy (RT) is commonly indicated for treatment of prostate cancer (PC). Biologicallyoptimised RT for PC may improve disease-free survival. This requires accurate spatial localisation and characterisation of tumour lesions. We aimed to generate a statistical, voxelised biological model to complement

multiparametric MRI data to facilitate biologically-optimised RT.

Ex vivo prostate MRI and histopathological imaging were acquired for 63 PC patients. These data were co-registered to derive three-dimensional distributions of graded tumour lesions and cell density. Novel registration processes were used to map these data to a common reference geometry. Voxelised statistical models of tumour probability and cell density were generated to create the PC biological atlas. Cell density models were analysed using the Kullback-Leibler divergence to compare normal vs. lognormal approximations to empirical data.

A reference geometry was constructed using ex vivo MRI space, patient data were deformably registered using a novel anatomy-guided process. Substructure correspondence was maintained using peripheral zone definitions to address spatial variability in prostate anatomy between patients. Three distinct approaches to interpolation were designed to map contours, tumour annotations and cell density maps from histology into ex vivo MRI space. Analysis suggests a log-normal model provides a more consistent representation of cell density when compared to a linear-normal model.

A biological model has been created that combines spatial distributions of tumour characteristics from a population into three-dimensional, voxelised, statistical models. This tool will be used to aid the development of biologically-optimised RT for PC patients.
