During its first years of existence, the Puerto Rico Transplant Program barely reached 18 to 20 renal transplants per year. A brain death amendment to the law improved the numbers but only to a stable thirty/year. Polls and studies showed that, although people knew about transplantation and expressed willingness to donate, the powerful emotional grief reaction, as well as a peculiar decision-making process, all militated against effective donation. In 1995, LifeLink of Puerto Rico was created as part of the very successful LifeLink Foundation of Tampa, staffed by local professionals. Cadaveric donation increased exponentially by 1227% and in 2004, 22.4 donors per million population were recovered, up from 1.5, one of the steepest growth curves in the United States. As a result, kidney transplantation increased, a cardiac transplant program was inaugurated, a pancreas transplant program has started, and liver will follow. The success is the result of well-trained, culturally sensitive coordinators and requestors; continuous education to the public, hospitals, administrators, neurospecialists, and critical care units; hospital development; implementation of federal law; and a sensitive approach the deceased donor family, and not only to the waiting list patients. The results demonstrate that organizational and educational factors can override cultural obstacles.

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).
