Article Synopsis
  • Environmental conditions, like climate variability, impact the costs and benefits of reproductive traits, affecting sexual selection.
  • The study focused on nuptial gift-giving spiders, examining how different climatic conditions influence male sexual traits and female mate choice.
  • Results showed that in highly variable environments, female choice is limited, leading to a preference for deceptive worthless gifts, while more stable environments promote better mate selection.

Background: Genetic polymorphisms have been associated with risk of antituberculosis treatment toxicity. We characterized associations with adverse events and treatment failure/recurrence among adults treated for tuberculosis in Brazil.

Methods: Participants were followed in Regional Prospective Observational Research in Tuberculosis (RePORT)-Brazil.

Article Synopsis
  • TB treatment response varies based on genetic ancestry, with a study in Brazil showing differing risks for adverse drug reactions (ADRs) linked to African and European ancestry.
  • Patients with a higher proportion of African ancestry had a lower risk of Grade 2+ ADRs, while those with higher European ancestry faced an increased risk; however, this trend changed for patients living with HIV.
  • The research involved 941 pulmonary TB patients, and no significant associations were found for Amerindian ancestry or other treatment outcomes in the cohort.

Article Synopsis
  • Digital health interventions, like remote symptom monitoring, could potentially lessen the economic impact of asthma and COPD, but their cost-effectiveness is uncertain, prompting a systematic review of randomized controlled trials (RCTs) to evaluate this.
  • The review included 35 RCTs, focusing on four types of digital interventions (electronic diaries, real-time monitoring, teleconsultations, and others), with mixed economic outcomes; most supported the cost-effectiveness of real-time monitoring and teleconsultations.
  • The full economic analyses showed a wide range of incremental cost-effectiveness ratios, while partial analyses highlighted cost differences between groups, with many low-bias studies indicating digital interventions were economically beneficial.

Article Synopsis
  • * This study aimed to analyze genetic variations (SNPs) related to the enzyme in a specific population, revealing that most individuals had slow or intermediate acetylation phenotypes.
  • * Identifying these genetic profiles can lead to personalized treatment strategies that improve patient outcomes, reduce treatment costs, and prevent drug-resistant strains of tuberculosis.

Asthma is a chronic inflammatory respiratory condition, characterized by variable airflow limitation, leading to clinical symptoms such as dyspnea and chest tightness. These symptoms result from an underlying inflammatory process. The β2 agonists are bronchodilators prescribed for the relief of the disease.

Article Synopsis
  • The Neotropical region is known for its incredible biodiversity, influenced by geological events such as the formation of the Andes and the closure of the Isthmus of Panama, which have shaped the landscape over millions of years.
  • Researchers conducted a comprehensive phylogenetic study of Micrathena spiders, involving 117 species, to explore their evolutionary history and how dispersal patterns have contributed to species diversity in the region.
  • Findings suggest that Andean cloud forests are hotspots for speciation, while the Amazon acts as a primary source for the dispersal of these spiders, supporting theories about historical biogeographical connections and confirming species exchanges over the past 20 million years.

Purpose: To analyse factors affecting the ability to use the digital asthma monitoring application Mask-Air in old-age individuals living in inland Portugal.

Patients And Methods: In this observational study, patients with medically confirmed asthma who agreed to participate were interviewed and subdivided into Non-users Group: those who could not use the application and Users Group: those who could. Sociodemographic and psychological data, comorbidities, and asthma status were compared between groups.

The South American palpimanid genus Fernandezina Birabn currently comprises 15 described species, all known from epigean environments. Representatives of Fernandezina are easily recognized by the unexpanded femora I in both sexes and by the dorsally extended opisthosomal scutum in males. Herein, F.

The Caatinga is a nucleus of seasonally dry tropical forest (SDTF) known as a hotspot of diversification and endemism. Despite its importance, this biome is still insufficiently sampled, resulting in extensive knowledge gaps regarding its species richness and composition. In this study we report two species of Xenoctenidae that are endemic to, and widely distributed in the Caatinga.

Several polymorphisms altering the activity have already been identified. The geographical distribution of variants has been extensively studied and has been demonstrated to vary significantly among different ethnic population. Here, we describe the genetic variability of human N-acetyltransferase 2 () gene and the predominant genotype-deduced acetylation profiles of Brazilians.

Article Synopsis
  • COVID-19, caused by SARS-CoV-2, can lead to severe respiratory issues linked to immune system dysregulation, including hyperactive innate immunity and decreased T cell counts.
  • The disease involves significant alterations in cells' energy metabolism, particularly glucose metabolism, which may contribute to severe outcomes through increased inflammatory responses.
  • Potential treatments proposed include non-toxic doses of 2-deoxy-D-glucose, GLUT 1 inhibitors, antioxidants like high-dose vitamin C, and N-acetylcysteine, aimed at managing inflammation and improving immune function in critically ill patients.

Article Synopsis
  • Bronchial asthma is a common chronic disease impacting people of all ages, characterized by various subtypes that can affect treatment and prognosis.
  • * Research on asthma phenotypes, using clinical and inflammatory parameters, is crucial for developing personalized treatment strategies, while metabolomics studies provide insight into the metabolic features associated with different asthma types.
  • * Despite progress, more in-depth, well-structured research is needed to explore asthma phenotypes effectively, including the integration of metabolomics into a comprehensive approach.

Zootaxa published more than a thousand papers on Araneae from 2002 to the present, including descriptions of 3,833 new spider species and 177 new genera. Here we summarise the key contributions of Zootaxa to our current knowledge of global spider diversity. We provide a historical account of the researchers that have actively participated as editors, and recognize the more than 1,000 reviewers without whom none of this would have been possible.

Understanding the prevalence of M. leprae infection in armadillos is important because of evidence from Brazil and other countries of an association between contact with armadillos and the development of Hansen's Disease (leprosy). Our aim was to characterize studies which have investigated natural M.

Vicariance and dispersal events, combined with intricate global climatic history, have left an imprint on the spatiotemporal distribution and diversity of many organisms. Anelosimus cobweb spiders (Theridiidae), are organisms ranging in behavior from solitary to highly social, with a cosmopolitan distribution in temperate to tropical areas. Their evolutionary history and the discontinuous distribution of species richness suggest that 1) long-distance overwater dispersal and 2) climate change during the Neogene (23-2.

Traditional conservation techniques for mapping highly biodiverse areas assume there to be satisfactory knowledge about the geographic distribution of biodiversity. There are, however, large gaps in biological sampling and hence knowledge shortfalls. This problem is even more pronounced in the tropics.

The spider genus Mecynogea comprises nine species distributed predominantly in the Neotropics. Although the genus has been revised recently, several aspects of its taxonomy and morphology are still unresolved. In this paper, Mecynogea infelix (Soares Camargo, 1948) is removed from the synonymy of Mecynogea bigibba Simon, 1903 and redescribed.
