Floodplains function as global hotspots for the natural production of methane. Some of this methane can be oxidized by methanotrophic bacteria and assimilated into their biomass before reaching the atmosphere. Consequently, aquatic invertebrates that feed on methanotrophic bacteria may transfer methane-derived carbon to higher trophic levels in the aquatic food chain.

Article Synopsis
  • The study explores the formation of intricate patterns, or "metamorphic tongues," in a system made up of a rotor and a Duffing oscillator, highlighting their unusual quasiperiodic and chaotic behaviors.
  • Researchers use Lyapunov exponents to map out self-similar islands of stability and chaos in the system's two-dimensional parameter space.
  • Notably, quasiperiodic shrimp-shaped domains exhibit features akin to periodic systems, including complicated behaviors like torus-doubling and torus-tripling.

Background: Dissecting intracranial aneurysms (DIAs) have been treated through endovascular reconstructive manners, such as flow diverters (FDs) and stent-assisted coiling (SAC). Notably, no robust evidence has compared both approaches. Hence, the authors conducted a meta-analysis to compare their outcomes.

The design of chemotherapeutic drug carriers requires precise information on their interaction with the plasma membrane since the carriers should be internalized by cells without disrupting or compromising the overall integrity of the membrane. In this study, we employ Langmuir monolayers mimicking the outer leaflet of plasma membranes of healthy and cancerous cells to determine the molecular-level interactions with a water-soluble calixarene derivative, -sulfonic acid calix[4]arene (SCX4), which is promising as drug carrier. The cancer membrane models comprised either 40% 1,2-dipalmitoyl--glycero-3-phosphocholine (DPPC) or 1,2-dioleoyl--glycero-3-phosphocholine (DOPC), 30% cholesterol (Chol), 20% 1,2-dipalmitoyl--glycero-3-phosphoethanolamine (DPPE), and 10% 1,2-dipalmitoyl--glycero-3-phospho-l-serine (DPPS).

Objective: This double-blind, split-mouth, randomized equivalence clinical trial aimed to evaluate the 18-month clinical performance of an ormocer-based single-shade resin composite compared with an ormocer-based multi-shade resin composite in non-carious cervical lesions (NCCLs).

Methods: One hundred and twenty restorations were performed on NCCLs with two restorative materials (n = 60): Admira Fusion X-tra resin composite (ormocer-based single-shade), and Admira Fusion resin composite (ormocer-based multi-shade). After rubber dam isolation, a universal adhesive was applied in the selective enamel etching strategy.

Objective: To develop a supervised machine learning model to predict the occurrence and intensity of tooth sensitivity (TS) in patients undergoing in-office dental bleaching testing various algorithm models.

Materials And Methods: Retrospective data from 458 patients were analyzed, including variables such as the occurrence and intensity of TS, basal tooth color, bleaching material characteristics (concentration and pH), intervention details (number and duration of applications), and patient age. Classification and regression models were evaluated using 5-fold cross-validation and assessed based on various performance parameters.

Background: Obtaining a perfect color match with resin composite presents a significant challenge. The chameleon effect has enabled resin composite to mimic the color of the adjacent tooth structure in vitro. This double-blind, split-mouth and equivalent randomized clinical trial evaluated the color matching of one-shade resin composite with chameleon effect versus multi-shade resin composite in non-carious cervical lesion restorations (NCCLs).

Background: The wet-bonding protocol has been used in the etch-and-rinse (ER) mode to maintain adhesive infiltration in demineralized dentin. This study answered the research question: "Do the retention rates and other secondary outcomes of composite restorations in non-carious cervical lesions (NCCLs) differ between dry- and wet-bonding techniques?"

Methods: The authors included randomized clinical trials in which NCCLs were restored with ER or universal adhesives applied under dry and moist dentin. Searches for eligible articles were performed in MEDLINE via PubMed, Web of Science, Cochrane Library, Brazilian Library in Dentistry, Latin American and Caribbean Health Sciences Literature, Scopus, Embase, and grey literature without language and date restrictions and updated in May 2024.

Kunth (Piperaceae) essential oil (EO) was evaluated for its toxicity and repellency against red imported fire ants (RIFA), Buren, and a hybrid (HIFA) of red ( and black ( Forel) imported fire ants. Through bioactivity-guided fractionation, two major components, elemicin and myristicin, were isolated from the EO. Removal of treated sand in a digging bioassay was used as the criterion for repellency.

Article Synopsis
  • Apigenin, a flavonoid thought to benefit cardiovascular health, was studied for its effects on vascular function in Spontaneously Hypertensive Rats (SHRs) to understand its mechanisms of action.
  • Vascular beds from SHRs were tested with varying doses of apigenin, showing that its ability to lower blood pressure depended on the presence of endothelial cells and was significantly reduced by inhibitors of nitric oxide and potassium channels.
  • The research concluded that apigenin causes vasodilation primarily through endothelial nitric oxide and calcium-activated potassium channels, suggesting its potential for therapeutic use in cardiovascular diseases and the need for more clinical studies.

This study assessed the hydrogen peroxide (HP) diffusion into the pulp chamber, bleaching efficacy (BE), surface roughness (Ra), and Knoop microhardness (KHN) of an experimental bleaching gel containing a hydroxyapatite-capsaicin composite (HAp-CAP). Human premolars were randomly assigned to three groups (n = 9) based on the dental bleaching gel used (50 min; one session): only 35% HP, 35% HP + HAp-CAP, and not exposed to bleaching (negative control; NC). HP diffusion (µg/mL) into the pulp chamber was assessed using UV-Vis spectrophotometry, and BE (ΔE, ΔE, and WI) was evaluated using a digital spectrophotometer.
