Proteomics of the Dark-Ventral-Patch Sexual Signal in Male Red Deer.

Sexual signals in animals encompass a variety of forms including visual, acoustic, and chemical signals that are fundamental for intra- and interspecific communication, including sexual selection processes. Among these, odor signals play a critical role. Chemical compounds involved in sexual signaling vary in nature, with lipids and proteins being particularly important.

How Problem Gambling Shapes Activities of Daily Living: A Narrative Inquiry.

Importance: People experiencing addiction often face difficulties completing their activities of daily living (ADLs). Little research exists on how problem gambling (PG)-a serious public health issue-intersects with ADLs.

Objective: To explore how PG shapes a person's ADLs.

Genome-wide SNP assessment of contemporary European red deer genetic structure highlights the distinction of peripheral populations and the main admixture zones in Europe.

Genome-wide technologies open up new possibilities to clarify questions on genetic structure and phylogeographic history of taxa previously studied with microsatellite loci and mitochondrial sequences. Here, we used 736 individual red deer (Cervus elaphus) samples genotyped at 35,701 single nucleotide polymorphism loci (SNPs) to assess the population structure of the species throughout Europe. The results identified 28 populations, with higher degrees of genetic distinction in peripheral compared to mainland populations.

Early Toxicity and Efficacy of Four Different Conditioning Regimens for Autologous Hematopoietic Cell Transplantation in Patients With Lymphoma: Impact of Drug Shortages in a Resource-Constrained Country.

High-dose therapy followed by autologous hematopoietic cell transplant (AHCT) remains a viable consolidation strategy for a subset of patients with relapsed or refractory (R/R) lymphomas. BEAM (carmustine, etoposide, cytarabine, and melphalan) is widely recognized as the predominant conditioning regimen due to its satisfactory efficacy and tolerability. Nevertheless, shortages of carmustine and melphalan have compelled clinicians to explore alternative conditioning regimens.

High-throughput analysis of the Trypanosoma cruzi minicirculome (mcDNA) unveils structural variation and functional diversity.

Trypanosoma cruzi causes Chagas disease and has a unique extranuclear genome enclosed in a structure called the kinetoplast, which contains circular genomes known as maxi- and minicircles. While the structure and function of maxicircles are well-understood, many aspects of minicircles remain to be discovered. Here, we performed a high-throughput analysis of the minicirculome (mcDNA) in 50 clones isolated from Colombia's diverse T.

Development of GO Move: A Website for Children With Unilateral Cerebral Palsy.

It is unknown if an online tool is wanted by therapists and parents of individuals with unilateral cerebral palsy (UCP) to support implementation of goal-directed home programs, and if wanted, the recommended features for the tool. The objective was to explore the experiences of therapists and parents who have implemented home programs, seek guidance on translating a paper-based home program toolbox into a mobile website, and develop the website. Qualitative descriptive methodology guided data collection using semi-structured interviews and thematic analysis, validated with field notes and member checking.

Aedes albopictus distribution in Ibagué, Colombia: Potential risk of arboviral outbreaks.

Introduction: Aedes albopictus is a vector for arboviruses, such as dengue, Zika, chikungunya, and yellow fever. The first A. albopictus reports on the American continent date back to 1985.

Latin American Cerebral Palsy Register (LATAM-CPR): study protocol to develop a collaborative register with surveillance of children with cerebral palsy in Latin American countries.

Introduction: Cerebral palsy (CP) is one of the leading causes of childhood disability globally with a high burden in low-income and middle-income countries (LMICs). Preliminary findings from the global LMIC CP Register (GLM CPR) suggest that the majority of CP in LMICs are due to potentially preventable causes. Such data are lacking in the Latin American region.

Comparative Analysis of Microsatellite and SNP Markers for Genetic Management of Red Deer.

The analysis of population genetic structure and individual multilocus heterozygosity are crucial for wildlife management and conservation. Microsatellite markers have traditionally been used to assess these genetic parameters. However, single-nucleotide polymorphisms (SNPs) are becoming increasingly popular.

From Watching to Calling: Linking Variations in an Entertainment-Education Storyline with Calls to a Health Hotline.

Substantial gaps exist in the theoretical conceptualization and practical development of entertainment-education, as studies often fail to account for the ways in which intrinsic message characteristics influence subsequent behavior. These gaps served as the impetus for an international collaborative project that evaluated ("Overcome the Fear"), a Spanish-language program that aired in Mexico from January to March 2020. The telenovela was produced with the aim of improving sexual and reproductive health knowledge and behaviors by modeling effective ways to discuss and negotiate safer sex practices.

Is the Intrasexual Competition in Male Red Deer Reflected in the Ratio of Stable Isotopes of Carbon and Nitrogen in Faeces?

Isotopic analysis of carbon and nitrogen in faeces is a reliable methodology for studying ecology in wildlife. Here, we tested this technique to detect variations in carbon and nitrogen isotopic ratios (δC and δN) in two different intrasexual competition scenarios of male Iberian red deer () using faeces of individuals collected during hunting actions in South-eastern Spain. The carbon isotopic ratio (δC) was not found to be significant, likely due to similar diet composition in all individuals.

Exploring the potential links between gut microbiota composition and natural populations management in wild boar (Sus scrofa).

We surveyed wild boar (Sus scrofa) populations using 16S rRNA gene analysis of the gut microbiota in fresh faeces taken from 88 animals hunted in 16 hunting estates. The wild boar is a very convenient model system to explore how environmental factors including game management, food availability, disease prevalence, and behaviour may affect different biological components of wild individuals with potential implications in management and conservation. We tested the hypotheses that diet (according to stable carbon isotopes analyses), gender (i.

Latin American consensus recommendations on the risk of infections in people with multiple sclerosis treated with disease modifying drugs.

Introduction: The emergence of several therapeutic options in multiple sclerosis (MS), which significantly modify the immune system functioning, has led to the need for the consideration of additional factors, such as risk of infections, in the decision-making process. The aim of these consensus recommendations was to discuss and perform a practical guide to Latin American neurologists on the risk of infections at diagnosis, follow-up and prior to initiation of DMDs.

Methods: A panel of Latin American neurologists, experts in demyelinating diseases and dedicated to management and care of MS patients, gathered during 2021 and 2022 to make consensus recommendations on the risk of infections in PwMS treated with DMDs in Latin America.

Graphene-TLL-CuONPs Hybrid as Highly Efficient Catalyst for Degradation of Organic Compounds.

In this work, CuO nanoparticles (NPs) were created in situ on graphene functionalized with lipase (G@TLL) where site-oriented supported TLL acted as template and binder in the presence of copper salt by tailorable synthesis under mild conditions, producing a heterogeneous catalyst. CuO NPs were confirmed by XRD and XPS. The TEM microscopy showed that the nanoparticles were homogeneously distributed over the G@TLL surface with sizes of 53 nm and 165 nm.

Genetic Diversity of Wild Boar and Deer.

Genetic diversity provides the long-term capacity of species, communities, and the biosphere to persist under change [...

Forage quality of consecutive years interact to affect body condition, reproductive rate and rut phenology in Iberian red deer.

Body condition for reproduction in capital breeders such as the red deer (Cervus elaphus) is mostly determined by their stored energy reserves. Thus, environmental conditions and resource availability may affect reproductive performance and breeding success. In warm Mediterranean regions, current climate change is driving to a hotter and drier scenario that is expected to affect the biology and dynamics of many populations.

Evaluation of candidate reference genes for quantitative real-time PCR normalization in blood from red deer developing antlers.

Sexual selection favors male traits that increase their ability to monopolize the breeding access to several females. Deer antlers are cranial appendages that regenerate annually in males. Throughout life, the phenology of antler growth advances and antler mass increases until the stag reaches, between 8 and 10 years old, maximum body mass and highest reproductive success.

Genome plasticity driven by aneuploidy and loss of heterozygosity in .

the causative agent of Chagas disease shows a marked genetic diversity and divided into at least six Discrete Typing Units (DTUs). High intra genetic variability has been observed in the TcI DTU, the most widely distributed DTU, where patterns of genomic diversity can provide information on ecological and evolutionary processes driving parasite population structure and genome organization. Chromosomal aneuploidies and rearrangements across multigene families represent an evidence of genome plasticity.

Molecular detection of Toxoplasma gondii in meat for human consumption in Ibague, Colombia.

Introduction: Toxoplasma gondii is a parasite with great zoonotic potential. It can infect a broad range of warm-blooded hosts (including livestock) and causes significant losses in the industry. In humans, it has been described as a pathogen in immunosuppressed people, it affects the fetus development in congenital infections, and is associated with various behavioral disorders in healthy people.

Stable carbon and nitrogen isotope values in hair reveal management differences and hidden practices in wild boar populations.

The analysis of stable isotopes in different tissues has been widely used to obtain information on the ecology and nutritional patterns of wildlife. The isotope ratios of the stable isotopes of carbon and nitrogen (δC and δN) analysed in different tissues are directly related to the animal's diet and, to some extent, to the environment where the individual has growth. Specifically, this type of analysis in hair samples has become relevant as it provides information on the quality and long-term composition of the diet that produced the isotope accumulation during the tissue growth.

Host Genetic Diversity and Infectious Diseases. Focus on Wild Boar, Red Deer and Tuberculosis.

Host genetic diversity tends to limit disease spread in nature and buffers populations against epidemics. Genetic diversity in wildlife is expected to receive increasing attention in contexts related to disease transmission and human health. Ungulates such as wild boar () and red deer () are important zoonotic hosts that can be precursors to disease emergence and spread in humans.

The dark-ventral-patch of male red deer, a sexual signal that conveys the degree of involvement in rutting behavior.

Background: In polygynous mammals, signalling may play a decisive role in mating behavior, mediating the intensity of male fights and female mate choice. During the rutting season, male red deer may show a visible dark patch in their ventral fur. Recently, this patch has been suggested to act as a flexible sexual signal, due to its relationships with other variables such as age, body size, antler development, volatile compounds, or the competitive environment.
