(2018-06-02)Background A key component of achieving universal health coverage is ensuring that all populations have access to quality health care. Examining where gains have occurred or progress has faltered ... -
Measuring progress and projecting attainment on the basis of past trends of the health-related Sustainable Development Goals in 188 countries: an analysis from the Global Burden of Disease Study 2016
(2017-09-16)Background The UN’s Sustainable Development Goals (SDGs) are grounded in the global ambition of “leaving no one behind”. Understanding today’s gains and gaps for the health-related SDGs is essential for decision makers as ... -
Measuring progress from 1990 to 2017 and projecting attainment to 2030 of the health-related Sustainable Development Goals for 195 countries and territories: a systematic analysis for the Global Burden of Disease Study 2017
(2018-11-10)Background Efforts to establish the 2015 baseline and monitor early implementation of the UN Sustainable Development Goals (SDGs) highlight both great potential for and threats to improving health by 2030. To fully deliver ... -
Measuring the health-related Sustainable Development Goals in 188 countries: a baseline analysis from the Global Burden of Disease Study 2015
(2016-10-08)In September, 2015, the UN General Assembly established the Sustainable Development Goals (SDGs). The SDGs specify 17 universal goals, 169 targets, and 230 indicators leading up to 2030. We provide an analysis of 33 ... -
Medusamide A, a Panamanian Cyanobacterial Depsipeptide with Multiple β‑Amino Acids
(2016-01-19)From a collection of marine cyanobacteria made in the Coiba National Park along the Pacific coast of the Republic of Panama a novel cyclic depsipeptide, given the trivial name medusamide A, has been isolated and fully ... -
Mitogenomics of Central American weakly-electric fishes
(2019-02-20)Electric fishes are a diverse group of freshwater organisms with the ability to generate electric organ discharges (EODs) that are used for communication and electrolocation. This group (ca. 200 species) has originated in ... -
Molecular Ecological Insights into Neotropical Bird–Tick Interactions
(2016-05-20)In the tropics, ticks parasitize many classes of vertebrate hosts. However, because many tropical tick species are only identifiable in the adult stage, and these adults usually parasitize mammals, most attention on the ... -
Molecular validation of anthropophilic Phlebotominae sandflies (Diptera: Psychodidae) in Central Panama
(2019-08-15)Six Phlebotominae sand fly species are incriminated as biological vectors of human pathogens in Panama, but molecular corroboration is still needed. We aim at confirming the identity of Phlebotominae species documented as ... -
Mosquito-Host Interactions during and after an Outbreak of Equine Viral Encephalitis in Eastern Panama
(2013-12-10)Mosquito blood meals provide information about the feeding habits and host preference of potential arthropod-borne disease vectors. Although mosquito-borne diseases are ubiquitous in the Neotropics, few studies in this ... -
Motor neuron disease-associated loss of nuclear TDP-43 is linked to DNA double-strand break repair defects
(2019-03-05)Genome damage and their defective repair have been etiologically linked to degenerating neurons in many subtypes of amyotrophic lateral sclerosis (ALS) patients; however, the specific mechanisms remain enigmatic. The ... -
