Projetos de vida de adultos jovens portadores de HIV por transmissão vertical: estudo exploratório com usuários de um ambulatório de infectologia Life projects of young adults with HIV acquired by vertical transmission: an exploratory study with patients of an infectious diseases' outpatients department

Saúde e Sociedade, 2012
Esta pesquisa teve o intuito de conhecer os projetos de vida de jovens adultos que convivem com o HIV/aids a partir da transmissão vertical, com relação a: estudo, trabalho e constituição familiar. Outro objetivo foi o de conhecer sua vivência no que diz respeito à assistência recebida. Como instrumentos, foram utilizados: questionário sociodemográfico

Tumbling Magnetic Microrobots for Targeted In Vivo Drug Delivery in the GI Tract

Advanced Robotics Research, EarlyView.
We introduce a microrobot design and integrated system for on‐demand targeted drug release in the gastrointestinal tract. The microrobot has an embedded magnet for actuation with external magnetic fields and is visualized in real time using ultrasound. It has two drug release ports sealed with a thermally sensitive wax. Local heating of the wax using a

A Central Somatic Transmission Mediates Proprioceptive Facilitation of Muscle Pain

Advanced Science, EarlyView.
Zhang et al. uncover a novel central mechanism for persistent muscle pain, in which TRPA1 sensitization in MeV proprioceptive neurons enhances somatic secretion. This, in turn, disinhibits descending pain control from neighboring noradrenergic locus coeruleus neurons via local GABAergic circuits, thereby promoting inflammatory muscle pain.

Zika Virus Attenuation by Codon Pair Deoptimization Induces Sterilizing Immunity in Mouse Models. [PDF]

, 2018
Zika virus (ZIKV) infection during the large epidemics in the Americas is related to congenital abnormities or fetal demise. To date, there is no vaccine, antiviral drug, or other modality available to prevent or treat Zika virus infection.

Paternal Circadian Disruption Impairs Offspring Cognition via Sperm microRNAs

Advanced Science, EarlyView.
Paternal circadian disruption remodels the sperm small RNA payload, elevating miR‐92a‐3p/miR‐25‐3p levels and perturbing early embryonic gene regulatory programs. Microinjection experiments and single‐embryo transcriptomics reveal sex‐specific developmental vulnerabilities, ultimately impairing offspring hippocampal synaptic plasticity and cognition ...

Control of mother-to-child transmission of infectious diseases in Brazil: progress in HIV/AIDS and failure in congenital syphilis Controle da transmissão vertical de doenças infecciosas no Brasil: avanços na infecção pelo HIV/AIDS e descompasso na sífilis congênita

Cadernos de Saúde Pública, 2007
In Brazil, syphilis and HIV infection are considered serious public health problems. However, in practice, epidemiological surveillance, prevention measures, and prenatal care seem to be more effective in the control of mother-to-child transmission of the HIV than in the control of transmission of the Treponema pallidum. Here we discuss the differences

Distribution and transmission of American foulbrood in honey bees [PDF]

, 2006
The distribution of Paenibacillus larvae spores, the causative agent of American foulbrood, was studied on three different levels in the honey bee system; the apiary level, the colony level and the individual honey bee level.

Timing Mechanotransduction: Mechanically Dynamic Biomaterials Reveal the Temporal Hierarchy of YAP/TAZ Control Nodes

Advanced Science, EarlyView.
This work develops dynamically softening polyacrylamide hydrogels for time‐resolved imaging during continuous mechanical transitions. The study revealed that mechanotransduction is biphasic; YAP/TAZ inactivation is driven by early loss of the nucleocytoskeletal continuum connecting subnuclear adhesions, F‐actin, and the nuclear envelope, coupled with ...

Allee Effects May Slow the Spread of Parasites in a Coastal Marine Ecosystem [PDF]

, 2011
Allee effects are thought to mediate the dynamics of population colonization, particularly for invasive species. However, Allee effects acting on parasites have rarely been considered in the analogous process of infectious disease establishment and ...

De Novo Multi‐Mechanism Antimicrobial Peptide Design via Multimodal Deep Learning

Advanced Science, EarlyView.
Current AI‐driven peptide discovery often overlooks complex structural data. This study presents M3‐CAD, a generative pipeline that leverages 3D voxel coloring and a massive database of over 12 000 peptides to capture nuanced physicochemical contexts.
