This article analyzes a contradiction facing efforts by left-leaning governments in Latin America to transform health into a fundamental social right. Policies and practices that confront health inequities generally fail to address health/communicative inequities, hierarchical distributions of rights to shape what counts as legitimate knowledge of health. This ethnographic analysis focuses on an epidemic of a mysterious disease - identified clinically as bat-transmitted rabies - in the Delta Amacuro rainforest of Venezuela in 2007-2008, tracing how parents who lost 1-3 children faced acute health/communicative inequities in clinical settings, epidemiological investigations, work with healers, news coverage, health policy, and health communication...

Polyketide synthase (PKS) derived natural products are biosynthesized by head-to-tail addition of acetate and malonate extender units resulting in linear extended-polyketide chains. Despite the well documented structural diversity associated with PKS derived natural products, C-C chain branching deviating from the usual linear pattern is relatively rare. Herein, type-II PKS angucyclic natural products containing a hemiaminal functionality were identified and proposed as the parent of a series of C-C branched analogues...

BACKGROUND: The gene encoding a thermostable cellulase of family 12 was previously isolated from a Rhodothermus marinus through functional screening. CelA is a protein of 260 aminoacyl residues with a 28-residue amino-terminal signal peptide. Mature CelA was poorly synthesized in some Escherichia coli strains and not at all in others. Here we present an alternative approach for its heterologous production as a secreted polypeptide in Streptomyces. RESULTS: CelA was successfully over-expressed as a secreted polypeptide in Streptomyces lividans TK24...

Age-specific intervention and assessment thresholds were developed for seven Latin American countries. The intervention threshold ranged from 1.2% (Ecuador) to 27.5% (Argentina) at the age of 50 and 90 years, respectively. In the Latin American countries, FRAX offers a substantial advance for the detection of subjects at high fracture risk. INTRODUCTION: Intervention thresholds are proposed using the Fracture Risk Assessment (FRAX) tool. We recommended their use to calculate the ten-year probability of fragility fracture (FF) in both, men and women with or without the inclusion of bone mineral density (BMD)...

The genus Racekiela Bass & Volkmer-Ribeiro, 1998 comprises six species of freshwater sponges distributed along the Palaearctic, Nearctic and Neotropical regions (Van Soest et al. 2017). They are characterized by an isodictyal skeleton solely of acanthoxeas, sparse spongin fibers, and tri-layered gemmules with radially embedded gemmoscleres of two types, short birotules and long pseudobirotules (Manconi & Pronzato 2002; Volkmer-Ribeiro & Machado 2007). Four species occur in the Northern Hemisphere: R. biceps (Lindenschmidt, 1950) from Michigan (Lindenschmidt 1950), R...

The genus Eburodacrys White, 1853 is redescribed. Four new species are proposed: Eburodacrys yolandae, from Colombia; E. eduardoi and E. bezarki, from Brazil, and E. santossilvai, from Venezuela. Eburodacrys curialis Gounelle, 1909; and Eburodacrys hesperidis Chemsak & Linsley, 1970 are proposed as synonyms of Eburodacrys nemorivaga Gounelle, 1909; and Eburodacrys amabilis Galileo & Martins, 2009 as synonym of Eburodacrys sulfurifera Gounelle, 1909. The genus is now composed of 89 species. The geographical distribution of 26 species is expanded and the specific locality in Colombia for E...

Three strains, CLM-U50T, CLM-R50 and IVIC-Bov1, belonging to the genus Leptospira, were isolated in Venezuela from a patient with leptospirosis, a domestic rat (Rattus norvegicus) and a cow (Bos taurus), respectively. The initial characterisation of these strains based on the rrs gene (16S rRNA) suggested their designation as a novel species within the 'intermediates' group of the genus Leptospira. Further phylogenomic characterisation based on single copy core genes was consistent with their separation into a novel species...

EDITORIAL
Sunil Daryanani
Adequate and modern health care is not available in Venezuela at this moment. A humanitarian crisis of post war dimensions is currently rampant and afflicting all Venezuelans alike. The delivery and availability of cancer care is severely limited and inadequate. No funding is available as populist measures, mismanagement, pillaging, corruption, lack of forethought and expertise have brought the country into severe economic collapse and political turmoil.

Ramfis Nieto-Martínez, Juan P González-Rivas, Pablo Aschner, Noël C Barengo, Jeffrey I Mechanick
BACKGROUND: Type 2 diabetes (T2D) imposes a heavy burden in developing countries, requiring effective primary prevention policies. Randomized clinical trials have identified successful strategies in T2D prevention. However, translating these results to real-life scenarios and adapting to ethnocultural differences is a major challenge. Transculturalization allows incorporating cultural factors to diabetes prevention strategies to optimize implementation of clinical trials results. The purpose of this paper is to review the transcultural adaptations developed for T2D prevention in Latin America (LA)...

D″ (Dee double prime), the lowermost layer of the Earth's mantle, is the thermal boundary layer (TBL) of mantle convection immediately above the Earth's liquid outer core. As the origin of upwelling of hot material and the destination of paleoslabs (downwelling cold slab remnants), D″ plays a major role in the Earth's evolution. D″ beneath Central America and the Caribbean is of particular geodynamical interest, because the paleo- and present Pacific plates have been subducting beneath the western margin of Pangaea since ~250 million years ago, which implies that paleoslabs could have reached the lowermost mantle...

Food allergy is a public health concern almost all over the world. Although most of the countries that regulate the declaration of allergens in prepackaged foods include the list recommended by the Codex Alimentarius, some countries have added other allergens to this list due to prevalence data and regional incidence, whereas others have incorporated exceptions for some products derived from allergenic foods. Within this context, the situation in Latin America regarding these regulations is diverse. Data about prevalence of food hypersensitivity are very limited in the region...
