Article Synopsis
  • This study focuses on Xenopus laevis, an important model organism in developmental biology, specifically regarding its late developmental stages, which are often underrepresented in research.
  • Researchers used micro-computed tomography (micro-CT) to create detailed 3D models of Xenopus at various stages from tadpoles to adults, highlighting morphological changes and structures such as the skeleton, teeth, and organs.
  • The resulting high-resolution dataset is a valuable resource for future studies in vertebrate development, with potential applications in virtual reality, 3D printing, and educational initiatives.

(1) Background: Sensory processing disorder is now recognised as a core feature of autism spectrum disorder that influences children's adaptive behaviours, which, in turn, may interfere with their participation in life situations. This study describes the process of developing a technological platform, in the form of an app, to help families regulate children with ASD, aged 3-6 years old, by applying sensory strategies to improve the child's participation in daily routines in the home context. (2) Methods: A focus group formed by four specialised occupational therapists who intervene with children with ASD was selected in order to understand and discuss content that should be included in the app.

Article Synopsis
  • Maintenance of genome integrity is essential for accurate DNA transfer during cell division, with DNA polymerases (Pols) playing key roles in both genome replication and DNA damage repair.* -
  • This study focuses on a specific translesion DNA polymerase, named TbPolIE, in African trypanosomes, revealing that its depletion causes slowed growth, altered DNA structure, and increased sensitivity to DNA damage.* -
  • Additionally, the localization of TbPolIE at the nuclear periphery is linked to chromosome segregation issues and suggests its role in helping the parasite evade host immune responses through changes in surface protein gene regulation.*

Fetal and placental growth disorders are common in maternal human immunodeficiency virus (HIV) infection and can be attributed to both the infection and comorbidities not associated with HIV. We describe placental growth disorders and adverse reproductive outcomes in HIV-infected pregnant women whose delivery occurred between 2001-2014 in Vitoria, Brazil. Cases with gestational age (GA) ≥ than 22 weeks validated by ultrasonography, with placental and fetal weight dimensions at birth, were studied.

Syphilis is a sexually transmitted infection (STI) caused by the bacterium Treponema pallidum and has shown a significant increase in recent decades. It may be associated with other STIs such as soft chancre or chancroid, which is an uncommon infection in Brazil. The presence of ulcerated genital lesions is associated with a higher risk of HIV transmission.

During its life cycle, Trypanosoma brucei shuttles between a mammalian host and the tsetse fly vector. In the mammalian host, immune evasion of T. brucei bloodstream form (BSF) cells relies on antigenic variation, which includes monoallelic expression and periodic switching of variant surface glycoprotein (VSG) genes.

Zika virus (ZIKV) is an emerging flavivirus that can cause birth defects and neurologic complications. Molecular tests are effective for diagnosing acute ZIKV infection, although the majority of infections produce no symptoms at all or present after the narrow window in which molecular diagnostics are dependable. Serology is a reliable method for detecting infections after the viremic period; however, most serological assays have limited specificity due to cross-reactive antibodies elicited by flavivirus infections.

Introduction: Maternal HIV infection and related co-morbidities may have two outstanding consequences to fetal health: mother-to-child transmission (MTCT) and adverse perinatal outcomes. After Brazilian success in reducing MTCT, the attention must now be diverted to the potentially increased risk for preterm birth (PTB) and intrauterine fetal growth restriction (IUGR).

Objective: To determine the prevalence of PTB and IUGR in low income, antiretroviral users, publicly assisted, HIV-infected women and to verify its relation to the HIV infection stage.
