The purpose of this study was to explore the health situation of women in Puerto Rico through the analysis of the causes of deaths in medical certification contained in death certificates. The data source used was the computer tape containing the data on deaths occurred in Puerto Rico during 1994. This tape was produced by the Puerto Rico Department of Health. The analysis of the main causes of deaths in women showed a trend associated with chronic and degenerative diseases. This trend is compatible with the one found in women over 65 years old. In women under 65 years of age, this trend was also observed, although other causes were also relevant, like deaths by external causes and AIDS. For the age groups of under 15, 15 to 44, 45 to 64 and 65 and over, the principal causes of deaths were: conditions related to the perinatal period, AIDS, cancer and heart and heart related diseases respectively. The degree of vulnerability to death from certain causes of mortality which changes in importance from one age range to another in the female population of Puerto Rico is shown by the results of this research project.

Despite significant strides in gender equity, the Nobel Prizes in STEM fields continue to exhibit glaring disparities in the recognition of women's contributions to science. Thirty years ago, only 3% of Nobel laureates in science were women; today, that number has increased marginally to 4%, raising the critical question: Why "still" so few? This opinion piece examines systemic inequities and structural barriers that hinder the equitable acknowledgment of women's and underrepresented groups' contributions to science. Data reveal that while women now comprise a significant proportion of degree recipients and workforce entrants in fields such as biomedical research and chemistry, their representation among Nobel laureates remains disproportionately low.

A structurally novel metabolite, fatuamide A (), was discovered from a laboratory cultured strain of the marine cyanobacterium sp., collected from Faga'itua Bay, American Samoa. A bioassay-guided approach using NCI-H460 human lung cancer cells directed the isolation of fatuamide A, which was obtained from the most cytotoxic fraction.

Introduction: Female sex workers are a vulnerable hard-to-reach group. Research in this field is scarce due to several issues, such as methodological difficulties or societal stigmatization. Most of the available literature focuses on sexually transmittable diseases.

This study takes Culebra, Puerto Rico, as the study area and attempts multi-temporal bathymetric inversion using 193 Sentinel-2 images and eight tracks of ICESat-2 ATL03 data. Two widely used machine-learning models, CatBoost and Random Forest (RF), were employed to construct bathymetric inversion models, and the Fusion followed by Inversion (FI) strategy and inversion followed by Fusion (IF) strategy were also compared.

Purpose: This study aimed to evaluate and compare the fracture resistance of long-span fixed provisional restorations fabricated using milling, three-dimensional (3D) printing, and conventional methods.
Materials And Methods: Sixty specimens were prepared, divided into four groups of 15 each, corresponding to four fabrication methods: computer-aided design and computer-aided manufacturing (CAD-CAM) milled provisional resins, 3D-printed provisional resins, 3D-printed permanent resins, and conventional bis-acryl restorations reinforced with wire. The specimens underwent a three-point bending test using a universal testing machine to measure fracture resistance, quantified as maximum force (in Newtons).
