The ability of recombinant adeno-associated virus (rAAV) vectors to deliver new genetic material to retinal neural and glial cells is well-documented, yet the precise targeting of vascular endothelial cells (VECs) presents a significant obstacle. In order to alleviate this limitation, we devised novel rAAV capsid mutant vectors with improved targeting affinity for retinal VEC. Serotype vectors of rAAV2/2, rAAV2/2[QuadYF-TV], and rAAV2/9 (n=9 capsid mutants per serotype), each carrying the GFP gene, were generated. Heptameric peptides (7 amino acids) were strategically placed at position 588 (for rAAV2/2 and rAAV2/2[QuadYF-TV]) or 589 (for rAAV2/9) of the virus protein (VP 1-3) to improve endothelial cell binding. Employing fluorescence microscopy and flow cytometry, the packaging and transduction efficiency of vectors in HEK293T and bovine VECs was evaluated. This yielded the identification of a mutant, EC5, that showed improved endothelial tropism when incorporated into all three capsid serotypes. In C57Bl/6j mice, intra-ocular and intravenous delivery of EC5 mutants resulted in a moderately improved transduction of the retinal vasculature, particularly around the optic nerve head, and further evidenced sinusoidal endothelial cell transduction in the liver. Intravenous injection of the rAAV2/2[QuadYF-TV] EC5 mutant yielded a striking and unanticipated surge in cardiac muscle transduction.

Intercellular communication, a potential role of microRNAs (miRNAs), are non-coding RNAs crucial in post-transcriptional genetic regulation. methylation inhibitor MiRNAs hold significant promise as biomarkers for ischemic heart disease. Invasive physiological evaluation provides a precise means of assessing each affected coronary compartment. Although research has shown a correlation between circulating microRNAs and markers of invasive physiological processes, their comprehensive relationship with coronary structures remains unexplored. This analysis focuses on evaluating the circulating microRNA profiles, categorized by the coronary vessel’s pattern of involvement.

This descriptive study, encompassing multiple sites in Spain, is being undertaken by investigators (NCT05374694). Invasive physiological evaluation, including fractional flow reserve (FFR) and microvascular resistance index (IMR), will be performed on one hundred consecutive patients aged over 18 with chest pain of presumed coronary cause, included in the study. Four initial patient groups will be established using FFR and IMR measurements to characterize macrovascular and microvascular involvement: FFR080 / IMR25, FFR080 / IMR less than 25, FFR greater than 080 / IMR 25, and FFR greater than 080 / IMR less than 25 representing normal coronary indexes. The acetylcholine test will also be performed on patients with only microvascular involvement or normal index values; the presence of spasm might lead to their classification as a fifth group. Using RT-qPCR, a panel of miRNAs previously implicated in the molecular mechanisms of chronic coronary syndrome will be examined.

Analysis of miRNA profiles linked to coronary affliction patterns will contribute to a clearer understanding of the mechanistic underpinnings of coronary pathology.

The study will yield miRNA profiles indicative of coronary lesion patterns, improving comprehension of the mechanistic processes driving coronary pathology.

To examine if intratumoral apparent diffusion coefficients (ADCs) demonstrate changes throughout cervical cancer treatment, and to investigate whether baseline ADC values or their modification after treatment are predictors for treatment effectiveness and overall survival in cervical cancer patients.

A retrospective cohort study enrolled 52 patients with inoperable cervical cancer who received chemoradiotherapy. Prior to treatment and after external beam radiotherapy (EBRT) combined with concurrent chemotherapy, diffusion weighted MRI was performed on each patient. Six consecutive diffusion-weighted magnetic resonance imaging (DW-MRI) scans were performed on 28 patients: one before treatment, one immediately following external beam radiation therapy (EBRT) and concurrent chemotherapy, and three during the image-guided brachytherapy (IGBT) treatment sessions, followed by one final scan after the entire treatment course was completed. The consistency of ADC measurements across different observers and techniques was evaluated by two independent observers who independently measured ADCs. This involved the freehand delineation of a large region of interest encompassing the entire tumor (L-ROI), as well as three smaller regions of interest (S-ROIs) within the zones experiencing the most restricted diffusion.

The reproducibility of L-ROIs and S-ROIs was the same. The apparent diffusion coefficients of the pretreatment ADCs were substantially higher in L-ROIs (883 mm²/s) than in S-ROIs (687 mm²/s), achieving statistical significance (P < 0.0001). ADC values exhibited a notable rise in the post-EBRT scans compared to the scans taken before treatment, demonstrating statistically significant differences in the left region of interest (L-ROI) (P < 0.0001) and the same region of interest (S-ROI) (P = 0.0001). The ADCs maintained a persistently higher level than pre-treatment values, encompassing the entire IGBT. The magnitude of ADC increases in S-ROIs, from pretreatment to post-EBRT MRI, was a strong predictor of improved overall patient survival (P = 0.018).

A notable surge in ADC values is frequently observed concurrent with cervical cancer treatment. A superior overall survival rate was more frequently associated with a larger difference in ADC values from pretreatment to post-EBRT treatment, using S-ROIs as the measurement tool. Future studies should prioritize standardized methods for determining both the timing and delineation of ADC measurements.

A substantial rise in ADC values is frequently observed during cervical cancer treatment. Superior increases in ADC values, observed from pre-treatment to post-EBRT, were indicative of enhanced overall survival, utilizing S-ROIs. Standardized methods for determining the timing and outlining of ADC measurements are recommended for future research.

The high prevalence of stunting is a significant concern in South Sulawesi and West Sulawesi. Investigations show a correlation between household situations, parental figures’ roles, and children’s attributes and stunting. This paper analyzed the 2013 and 2018 Indonesia Basic Health Survey data to pinpoint the determinants of stunting amongst children under five in South and West Sulawesi.

A secondary data analysis, using the 2013 and 2018 Indonesian Basic Health Surveys, was undertaken for this study. The 2013 and 2018 Indonesia Basic Health Surveys were utilized to examine children under five years old, with 3641 and 4423 participants, respectively, found in South Sulawesi Province. Similarly, in West Sulawesi Province, these surveys showed 804 and 1059 participants, respectively. A multivariable Poisson regression model was utilized to ascertain the determinants of stunting.

Data from the 2013 survey, encompassing children from South and West Sulawesi Provinces, showed a mean age of 311 months and 308 months, respectively. This contrasts with the mean ages of 296 and 291 months recorded in the 2018 survey. The 2013 survey in South Sulawesi Province found that household characteristics, maternal factors, and child-related factors significantly correlated with stunting in children under five. These factors included having two or more children under five (APR124; 95% CI 11-13; p=0.0006), maternal BMI (APR 11; 95% CI 103-11; p<0.0001), maternal weight (APR 09; 95% CI 094-097; p<0.0001), children aged 12-23 months (APR 22; 95% CI 17-27; p<0.0001), children aged 24-59 months (APR 22; 95% CI 18-27; p<0.0001), and birth weight (APR 19; 95% CI 15-25; p<0.0001). The 2018 survey found key determinants of various outcomes. Maternal weight (APR 09; 95% CI 098-099; p-value = 0005) was a significant factor, as were mothers with limited education (no education or only primary; APR 15; 95% CI 13-19; p-value = <0001), middle school education (APR 13; 95% CI 11-16; p-value = 0014), height below 151cm (APR 13; 95% CI 15-31; p-value = <0001), height between 151-160cm (APR 13; 95% CI 11-16; p-value = 0014), children aged 12-23 months (APR 22; 95% CI 17-28; p-value = <0001) and 24-59 months (APR 25; 95% CI 20-32; p-value = <0001). The observed birth weight on April 15th (95% CI: 12-19) was statistically significant (p < 0.0001). The 2013 survey in West Sulawesi Province examined factors contributing to stunting in children under five. The results indicated a significant link between stunting and residence in poor households (APR 19; 95% CI 11-33; p-value = 0021). Furthermore, children living with three or more siblings under five years old (APR 18; 95% CI 12-27; p-value = 0002) and those specifically within the age brackets of 12 to 23 months (APR 18; 95% CI 12-26; p-value = 0006) and 24 to 59 months (APR 19; 95% CI 13-27; p-value = 0001) were found to be at higher risk of stunting. The 2018 survey highlighted several key determinants: maternal BMI (APR 102; 95% CI 101-103; p-value = 0004), maternal weight (APR 09; 95% CI 095-098; p-value = <0001), mothers’ educational attainment (no education/primary: APR 19; 95% CI 13-27; p-value = 0001), middle school education (APR 19; 95% CI 13-27; p-value = 0001), high school education (APR 18; 95% CI 12-26; p-value = 0004), child age (12-23 months: APR 21; 95% CI 14-30; p-value = <0001), (24-59 months: APR 26; 95% CI 19-36; p-value = <0001), male gender (APR 12; 95% CI 101-14; p-value = 0035), and acute respiratory infection (ARI) (APR 16; 95% CI 104-25; p-value = 0030).

Stunting among under-five children in South Sulawesi Province is significantly influenced by several factors: household size in relation to young children, maternal education, maternal weight, maternal height, maternal body mass index, the child’s age at measurement, and birth weight. Among children under five in West Sulawesi, wealth status, maternal education level, maternal weight, maternal body mass index, child’s age, child’s gender, and prior episodes of acute respiratory infections all played a role in determining stunting. Subsequently, interventions must be implemented for households, children, and maternal sociodemographic factors.
