Buprenorphine has superior safety in opioid use disorder compared with alternatives due to its action as a partial opioid agonist, which limits its ability to cause respiratory depression. There is a risk of precipitated opioid withdrawal after buprenorphine exposure in someone using full opioid agonists. Buprenorphine induction strategies that avoid precipitated withdrawal remain a crucial component for starting buprenorphine in individuals actively using opioids.

Purpose: To assess the impact of staining and multiple firings on the mechanical, optical, and surface characteristics of zirconia-containing lithium silicate ceramics (ZLS).

Materials And Methods: Ninety ZLS discs (Suprinity, VITA Zahnfabrick) were divided according to the "Number of firings" protocol: Ctr-control, no characterization; SC-single firing cycle (for characterization, crystallization and staining simultaneously); and DC-double firing cycle (crystallization firing cycle was performed separately from the staining firing). Extrinsic pigmentation was performed to replicate the characterization of a monolithic restoration.

We studied the ultrastructure of the ultrablack cuticle in , an enigmatic and visually striking species of velvet ants (Hymenoptera, Mutillidae). Using a combination of scanning electron microscopy (SEM), transmission electron microscopy (TEM), confocal laser scanning microscopy (CLSM), and optical spectroscopy, we conducted a comprehensive analysis of the cuticle to elucidate its unique optical properties. SEM imaging provided a detailed surface morphology, while TEM provided insights into the internal structure.

Background And Purpose: Prolonged survival of neutrophils is essential for determining the progression and severity of inflammatory and immune-mediated disorders, including gouty arthritis. Survivin, an anti-apoptotic molecule, has been described as a regulator of cell survival. This study aims to examine the effects of YM155 treatment, a survivin selective suppressant, in maintaining neutrophil survival in vitro and in vivo experimental settings of neutrophilic inflammation.

Buprenorphine is an effective treatment for opioid use disorder but can be slow when using a standard low-dose titration protocol to avoid precipitated withdrawal. This presents a substantial practical barrier in clinical practice. Recent low-dose induction strategies have attempted to simplify and shorten the process required for successful induction, including our own transdermal buprenorphine method, which achieves induction to sublingual buprenorphine/naloxone after 48 h.

The fruit of Spondias mombin (cajazeira) is widely consumed in the northeast region of Brazil. In this work, three different extraction methods, namely ultrasound-assisted extraction (UAE), turbo-extraction (TE) and pressurized hot water extraction (PHWE), were evaluated in order to investigate the potential of cajazeira leaves as an alternative source of bioactive compounds. The extraction methods were compared in terms of yield, chemical composition and total phenolic content (TPC) of the extracts.

From Darwin's visit to nowadays, we analyzed the changes in species- and genus-level richness and turnover, equity, diversity, composition, as well as functional group and functional strategy dynamics over a 213-year historical series of the seaweed assemblage from Rio de Janeiro Bay. We developed new analysis methods to serve as a protocol for worldwide functional and bioindicator assessment of seaweed assemblages. Over the two centuries of changes tracked, the integration of taxonomic, functional group, and functional strategy analyses unraveled a trajectory of seaweed assemblage restructuring under human disturbance.

Despite advancements in cancer immunotherapy, most lymphomas remain unresponsive to checkpoint inhibitors. P-selectin glycoprotein ligand-1 (PSGL-1), recently identified as a promoter of T-cell exhaustion in murine melanoma models, has emerged as a novel immune checkpoint protein and promising immunotherapeutic target. In this study, we investigated the potential of PSGL-1 antibody targeting in B-cell lymphoma.

Background: Sarcopenia is a common condition in women with breast cancer, however still presents limitations for an effective diagnosis. This study aimed to evaluate the agreement and diagnostic accuracy of an anthropometric equation in diagnosing sarcopenia in women with breast cancer based on different constructs.

Methods: Cross-sectional study carried out with women with breast cancer aged ≥ 20 years.

Article Synopsis
  • The study focused on enhancing the interaction between modified gas vesicles (GVs) and the protease cathepsin B (CTSB) to analyze their ultrasound signals.
  • Researchers genetically engineered a protein (GvpC) to include a cleavage site for CTSB, expressed it in bacteria, and created modified GVs (GV*) for testing.
  • Results showed a significant increase in ultrasound signal intensity when the modified GVs interacted with CTSB, indicating that these GVs could serve as effective biosensors for detecting protease activity in tissues.

  • The study compared the risks of major adverse cardiovascular events (MACE) and all-cause death (ACD) in rheumatoid arthritis patients treated with JAK inhibitors (JAKi) or tocilizumab (TCZ) versus tumor necrosis factor inhibitors (TNFi).
  • A systematic review of randomized controlled trials showed that JAKi were associated with a non-significant increase in risks for MACE and ACD compared to TNFi, with Bayesian analysis indicating a higher probability of these events occurring with JAKi.
  • The analysis highlighted the need for more data, particularly on JAKi other than tofacitinib, to make informed regulatory recommendations regarding their use.

Seaweeds are the most phylogenetically diverse group of multicellular organisms and rank foremost among marine keystone species. Due to their taxonomic diversity and functional importance, previous studies have classified seaweeds into functional groups based on qualitative or semi-quantitative traits, such as seaweed form, anatomy, and thickness. Despite the widespread use of seaweed functional groups from basic marine ecology to coastal monitoring, it is not known how accurate such morphology-based proposals are in grouping seaweeds by their form.

Unlabelled: Currently, there are no specific antiviral therapeutic approaches targeting Human papillomaviruses (HPVs), which cause around 5% of all human cancers. Specific antiviral reagents are particularly needed for HPV-related oropharyngeal cancers (HPVOPCs) whose incidence is increasing and for which there are no early diagnostic tools available. We and others have demonstrated that the estrogen receptor alpha (ERα) is overexpressed in HPVOPCs, compared to HPV-negative cancers in this region, and that these elevated levels are associated with an improved disease outcome.

Characterizing the effects of saturated fat intake on metabolic health and its changes remains a major challenge. Lipid diets, from different sources, vary widely in their physiological effects on health; therefore, it is important to consider the specific lipid source consumed. The objective of the study was to evaluate the effect of the imposition of isocaloric diets with different lipid sources in zebrafish (fish oil/pork lard).
