1. Mercury Concentration in Liver Tissues of South American Fur Seals (Arctocephalus australis) from Southwestern Atlantic Ocean
Mercury (Hg) contamination of oceans is rapidly increasing, however Hg bioaccumulation in pinnipeds has been understudied. Here, we report for the first time Hg concentration in liver tissues of South American fur seals (Arctocephalus australis) in South and Southeast Brazil. Hg concentration was determined in twenty-five fur seals’ specimens found strande

2. Nutrition and Cardiovascular Diseases: Programming and Reprogramming
Abstract The Developmental Origin of Health and Disease (DOHaD) is an area of science dedicated to studying the processes by which insults during critical periods of mammals development leading to physiological changes resultig in diseases throughout life. Studies point to a complex interaction between nutritional status in early life and cardiovascular syst

3. Identification of Potential Human Protein Targets for Soybean Isoflavones
Soy isoflavones have been reported as endocrine disruptors due to their ability to modulate the activity of estrogen receptors (ERs) in mammals; however, its ability to modulate other metabolic pathways is not entirely clear, which makes it necessary to identify new pharmacological targets that interact with these compounds present in soybean. In this work,

4. Is it still worth Publishing Case Reports? They are Part of our Lives
Partially hydrogenated soybean oil and palm olein are oils that are widely used in the food industry. Continuous contact with air may cause changes of the triglycerides chemical structure, to eventually produce substances of lower molar masses that may be toxic to mammals. This study aimed to determine the kinetic parameters for the thermal oxidation of thes

6. Synthesis and Evaluation of Nematicidal Activity of Compounds Derived from Norbornadiene
Nematode is a major problem in agriculture, the effective way to control this pest is through chemical control, but the efficient molecules present in the market have great toxicity to mammals and birds. Thus, there is a constant demand for the development of new nematicide molecules. This study describes the synthesis of 21 novel esters derived from norborn

7. The effects of two abundant ant species on soil nutrients and seedling recruitment in Brazilian Atlantic Forest
ABSTRACT Ants can influence soil fertility and the spatial distribution of seeds, with possible effects on seedling recruitment. The ant species Pachycondyla striata Fr. Smith, 1858 and Odontomachus chelifer (Latreille, 1802) co-occur in many forest areas in the Neotropics. We assessed soil fertility and seed bank structure in soil samples close and distant

9. Evidence of a sylvatic enzootic cycle of Leishmania infantum in the State of Amapá, Brazil
Abstract INTRODUCTION: Leishmania infantum was considered to be absent from Amapá until 2017 when canine infection was detected. However, there is a lack of knowledge about which reservoir species are involved in transmission in this region. METHODS: Between 2014 and 2016, 86 samples from wild mammals and 74 from domestic dogs were collected in Wajãpi I

11. Aspects of embryo-maternal communication in establishment of pregnancy in cattle
Abstract Establishment of pregnancy in mammals requires reciprocal molecular communication between the conceptus and endometrium that modifies the endometrial transcriptome and uterine luminal milieu to support pregnancy. Due to the small size of the early embryo and elongating conceptus relative to the volume of the uterine lumen, collection of endometrium

12. Detection of Snps in the Melanocortin 1-Receptor (MC1R) and Its Association with Shank Color Trait in Hs Chicken
ABSTRACT The melanocortin 1 receptor (MC1R) gene plays a key role in controlling the deposition of melanin. In mammals, the MC1Rgene is regarded as a major candidate gene in the control of melanin formation. In domestic animals, the MC1R gene mainly controls the expression of coat, skin, and plumage color in mammals and birds. In order to breed chickens with
