Background: A low proportion of P. vivax-exposed individuals acquire protective strain-transcending neutralizing IgG antibodies that are able to block the interaction between the Duffy binding protein II (DBPII) and its erythrocyte-specific invasion receptor. In a recent study, a novel surface-engineered DBPII-based vaccine termed DEKnull-2, whose antibody response target conserved DBPII epitopes, was able to induce broadly binding-inhibitory IgG antibodies (BIAbs) that inhibit P.

Any combination of abnormal positioning of the ankle, hindfoot, midfoot, and forefoot is possible in the context of cerebral palsy, but some patterns are more common than others. The purpose of this article is to discuss the radiographic manifestations and surgical management of the following common conditions: equinus, equinoplanovalgus, equinocavovarus, vertical talus, oblique talus, hallux valgus, and ankle valgus. CP is defined by abnormalities of the developing fetal or infant brain that result in permanent central motor dysfunction.

The commensal bacteria causes several intestinal and extra-intestinal diseases, since it has virulence factors that interfere in important cellular processes. These bacteria also have a great capacity to spread the resistance genes, sometimes to phylogenetically distant bacteria, which poses an additional threat to public health worldwide. Here, we aimed to use the analytical potential of MALDI-TOF mass spectrometry (MS) to characterize isolates and identify proteins associated closely with antibiotic resistance.

In the Amazon basin, indigenous forest-dwelling communities typically suffer from a high burden of infectious diseases, including malaria. Difficulties in accessing these isolated ethnic groups, such as the semi-nomadic Yanomami, make official malaria data largely underestimated. In the current study, we longitudinally surveyed microscopic and submicroscopic malaria infection in four Yanomami villages of the Marari community in the northern-most region of the Brazilian Amazon.

relapse is one of the major causes of sustained global malaria transmission. Primaquine (PQ) is the only commercial drug available to prevent relapses, and its efficacy is dependent on metabolic activation by cytochrome P450 2D6 (CYP2D6). Impaired CYP2D6 function, caused by allelic polymorphisms, leads to the therapeutic failure of PQ as a radical cure for malaria.

Article Synopsis
  • Extreme droughts have hit the Amazon every 5 years in the 21st century, peaking in 2015, leading to increased biomass burning (BB) that negatively impacted air quality.
  • The study focused on air quality in Manaus, Brazil, during wet and dry seasons of 2015 and 2016, coinciding with a strong El Niño event that intensified BB occurrences.
  • Analysis showed a significant rise in particulate matter, with carbon monoxide levels increasing by 15% and levoglucosan by 500% due to heightened BB during the El Niño, suggesting future air quality degradation if droughts and BB continue.

Methicillin-resistant (MRSA) is an important clinical problem. In 2005, a livestock-associated MRSA clone was described, named CC398, being mostly associated with pigs, and causing colonization and infection in pigs and in related humans. The prevalence of these strains in food-producing pigs raised concerns about the possibility of MRSA-CC398 being a foodborne pathogen.

Background: Approximately 70% of cancer-related deaths occur in low- and middle-income countries. In addition to social and racial inequalities, treatment options in these countries are usually limited because of the lack of trained staff and equipment, limited patient access to health services, and a small number of clinical guidelines.

Objectives: The Brazilian Society of Surgical Oncology developed this guideline to address these barriers and guide physicians treating patients with endometrial cancer (EC) in regions with limited resources and few specialized centers.

Introduction: Pharmacological interventions to address behavioural and psychological symptoms of dementia (BPSD) can have undesirable side effects, therefore non-pharmacological approaches to managing symptoms may be preferable. Past studies show that music therapy can reduce BPSD, and other studies have explored how formal caregivers use music in their caring roles. However, no randomised study has examined the effects on BPSD of music interventions delivered by informal caregivers (CGs) in the home setting.

The number of draft genomes deposited in Genbank from the National Center for Biotechnology Information (NCBI) is higher than the complete ones. Draft genomes are assemblies that contain fragments of misassembled regions (gaps). Such draft genomes present a hindrance to the complete understanding of the biology and evolution of the organism since they lack genomic information.

Cerebral palsy is a neurologic condition with myriad musculoskeletal and articular manifestations. While every patient is unique with innumerable variations in presentation, symptoms and treatments, there are broad themes and recognizable patterns of development. Many of these findings spill over to other neurodevelopmental disorders, and lessons learned from children with cerebral palsy translate well to multiple neurologic conditions.

Background: Atopic dermatitis (AD) pathogenesis still needs to be elucidated, but invariant natural killer T (iNKT) cell involvement was already described by several groups. Our group has demonstrated that IgG antibodies purified from AD patients can modulate cytokine production by thymic T cells. Here we aimed to investigate if IgG from AD patients can modulate infant non-atopic thymic iNKT cells cytokine production in order to collaborate with the elucidation of AD development in infancy.
