Background: Higher than standard doses of rifampicin could improve the treatment outcome of drug-susceptible tuberculosis without compromising the safety of patients.

Methods: We performed a systematic review of prospective clinical studies including adults with pulmonary and extrapulmonary TB receiving rifampicin doses above 10mg/kg/day. We extracted the data on overall adverse events (AE), hepatic AE, sputum culture conversion (SCC) at week 8, recurrence, mortality, and pharmacokinetics.

Angiosarcoma is a rare soft tissue sarcoma, namely when it presents as a primary intradural extramedullary spinal neoplasm, with only one case of non-vertebral origin reported in the literature. We present the case of a 51-year-old woman with neurological symptoms of paraparesis and constipation who underwent a magnetic resonance imaging (MRI) that revealed a well-demarcated, predominantly homogeneous, intensely enhancing intradural extramedullary lesion in T2-weighted images. Histology, immunohistochemistry, and genetics of the lesion showed an angiosarcoma.

Biodiesel offers an alternative to fossil fuels, primarily because it is derived from renewable sources, with the potential to mitigate issues such as pollutant and greenhouse gas emissions, resource scarcity, and the market instability of petroleum derivatives. However, lower durability and stability pose challenges. To address this, researchers worldwide are exploring technologies that employ specific molecules to slow down biodiesel's oxidation process, thereby preserving its key physicochemical properties.

The Plasmodium falciparum cytoplasmic tyrosine tRNA synthetase (PfTyrRS) is an attractive drug target that is susceptible to reaction-hijacking by AMP-mimicking nucleoside sulfamates. We previously identified an exemplar pyrazolopyrimidine ribose sulfamate, ML901, as a potent reaction hijacking inhibitor of PfTyrRS. Here we examined the stage specificity of action of ML901, showing very good activity against the schizont stage, but lower trophozoite stage activity.

Cyclic nucleotide-dependent phosphodiesterases (PDEs) play essential roles in regulating the malaria parasite life cycle, suggesting that they may be promising antimalarial drug targets. PDE inhibitors are used safely to treat a range of noninfectious human disorders. Here, we report three subseries of fast-acting and potent PDEβ inhibitors that block asexual blood-stage parasite development and that are also active against human clinical isolates.

Gangliogliomas (GG) are rare primary central nervous system (CNS) tumors. These CNS tumors are more commonly located at the supratentorial level. The treatment of choice for these tumors is surgical resection, and the role of radiotherapy remains controversial.

Article Synopsis
  • A new species of trematode was identified in the intestine of the Brazilian catfish, using both morphological features and molecular techniques for analysis.
  • The new species is similar to another species described in 1978 but differs in oral and ventral sucker sizes and vitellaria distribution.
  • Phylogenetic analysis revealed that the new species is closely related to existing species, showing low genetic divergence, which supports its classification as a unique taxon within the broader genus.

Malaria control and elimination efforts would benefit from the identification and validation of new malaria chemotherapeutics. Recently, a transgenic line was used to perform a series of high-throughput in vitro screens for new antimalarials acting against the parasite sexual stages. The screens identified pyrimidine azepine chemotypes with potent activity.

The SO-generating pads contain different concentrations of sodium metabisulfite, which absorbs water from the grapes' transpiration, releasing SO gas, and there are slow-(SlowSO) and dual (DualSO)-releasing pads (fast release in the first 48 h and slow for up to 60 days). The ultra-fast SO-generating pad (FieldSO) releases the SO quickly for up to 6 h, and it was designed to be used soon after the harvest and until the grapes' packaging. The goal was to study the effect of FieldSO associated with SlowSO and DualSO pads on gray mold incidence and physicochemical and appearance characteristics of 'Italia' table grapes.

Background/objectives: The oral administration of hydrolyzed collagen peptides is a scientifically validated intervention for enhancing skeletal muscle health and performance. This integrative review consolidates the evidence supporting the use of low molecular weight collagen peptides (2000-3500 daltons) for their superior bioavailability and absorption. Our objective was to review the effects of collagen peptide or hydrolyzed collagen supplementation on muscle damage, recovery, and construction related to physical exercise.

Background: Citrulline malate (CM), especially when used in conjunction with physical exercise, has demonstrated potential as a non-pharmacological adjunct in the management of hypertension. Nevertheless, its impact on nocturnal blood pressure dipping remains unexplored.

Objective: Evaluate the impact of a single dose of CM on nocturnal blood pressure dipping after exercise in hypertensive individuals.

Article Synopsis
  • This study explored the relationship between dietary antioxidant capacity (dTAC) and the total antioxidant capacity from specific food groups (fgTAC) with the sleep duration of Brazilian graduates.
  • It involved an analysis of 6,387 graduates, classifying their sleep patterns as short, normal, or long based on the hours slept per night.
  • The findings suggest some links between certain food groups and sleep time, but no conclusive connection between higher dTAC and sleep duration, indicating a need for further long-term studies.

Background: Although important information concerning COVID-19 vaccination is available, the effects of the CoronaVac and ChadOx-1 vaccines on immunity and the redox balance in the upper airway mucosa of the aged population are not fully understood. Therefore, the aim of this study was to investigate the impacts of two doses of the CoronaVac or ChadOx-1 vaccine on immune/inflammatory responses and oxidative stress in the airway mucosa of older adults.

Methods: Seventy-six older adults of both sexes, with a mean age of 75.

  • This study looked at how being exposed to certain chemicals called phthalates during pregnancy could affect a baby's memory when they are around 7.5 months old.
  • Phthalates are found in many products we use, and they might cause extra stress in the body, known as oxidative stress.
  • The researchers found that higher levels of certain phthalates in pregnant mothers were linked to more oxidative stress and could affect how well babies remember new things.

Article Synopsis
  • - Receptor tyrosine kinases (RTKs) play crucial roles in cell functions like growth and differentiation, and when their signaling is disrupted, it can lead to tumors and make treatments less effective.
  • - This study analyzed gene expressions of specific RTKs (TAM, RON, EPHA2, and MET) in breast cancer tissues using qPCR, focusing on how these expressions relate to clinical data.
  • - Findings suggest that the expression of TYRO3, MET, and EPHA2 is associated with factors like tumor subtype, patient age, and lifestyle choices such as smoking and obesity, indicating their potential significance in breast cancer.

Background: Approaches to documenting the software patterns of a system can support intentionally and manually documenting them or automatically extracting them from the source code. Some of the approaches that we review do not maintain proximity between code and documentation. Others do not update the documentation after the code is changed.

  • Tuberculosis (TB) is a significant global health issue, particularly for children and adolescents in high-prevalence areas, where understanding treatment abandonment factors is limited.
  • This study analyzed data from 12,256 TB cases in São Paulo, Brazil, from 2009 to 2019, identifying 941 cases of treatment abandonment and highlighting higher rates among Black or brown adolescents, those over 11 years old, and incarcerated youth.
  • Risk factors for abandoning treatment included living with HIV/AIDS, previous TB treatment history, substance use, and self-administered treatment, emphasizing the need for targeted strategies to improve adherence to TB treatment.

Bioinformatics has emerged as a valuable tool for screening drugs and understanding their effects. This systematic review aimed to evaluate whether in silico studies using anti-obesity peptides targeting therapeutic pathways for obesity, when subsequently evaluated in vitro and in vivo, demonstrated effects consistent with those predicted in the computational analysis. The review was framed by the question: "What peptides or proteins have been used to treat obesity in in silico studies?" and structured according to the acronym PECo.
