Cellulose nanofiber (CNF) has been widely used as a flexible and lightweight polymer matrix for electromagnetic shielding and thermally conductive composite films because of its excellent mechanical strength, environmental performance, and low cost. However, the lack of flame retardancy seriously hinders its further application. Herein, renewable and biomass-sourced l-arginine (AR) was used to surface-modify ammonium polyphosphate (APP) and an environmentally friendly biobased flame retardant was synthesized by the coordination of zinc sulfate heptahydrate (ZnSO·7HO), which was named AAZ.

Four kinds of hydrophobic magnetic deep eutectic solvents (HMDESs) were prepared and applied to RNA extraction. Based on the HMDESs, a mechanical shaking-assisted liquid-liquid extraction (MSLLE) was developed for the extraction of RNA. Factors that influence the extraction, including the extraction time, temperature, volume of HMDES, buffer types, and pH, were evaluated.

However, the underlying mechanisms referred to the regulation of endogenous IL-33 production are not fully illustrated. Paeoniflorin (PF) has been reported to possess multiple pharmacological activities, including anti-inflammation and anti-allergy.

Allergic contact dermatitis (ACD), characterized predominantly by erythema, vesiculation, and pruritus, is a T cell-mediated skin inflammatory condition. Among immune cells involved in ACD, mast cells (MCs) play an essential role in its pathogenesis. As an inhibitor of proinflammatory IL-1 family members, interleukin 37 (IL-37) has been shown to ameliorate inflammatory responses in various allergic diseases.

Sinomenine (SIN), an alkaloid isolated from plant, possesses many pharmacological properties, such as anti-inflammation, anti-hyperalgesia, anti-allergy, anti-apoptosis, and anti-angiogenesis. In this study, we aimed to investigate the detailed molecular mechanisms associated with the anti-inflammatory activity of SIN in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages.
View Article and Find Full Text PDFLPS has been widely used to induce inflammatory pain, attributing to production of inflammatory cytokines and sensitization of nociceptors. Paeoniflorin (PF) possesses anti-nociceptive property, but its effect on LPS-induced inflammatory pain has not been investigated. In this study, we aimed to investigate the analgesic effect of PF on an inflammatory pain mouse model and explore the underlying mechanisms.

Transient receptor potential vanilloid 1 (TRPV-1) has been indicated to take part in cerebral protection of EA; however, the detailed mechanisms remain unclear. The aim of this study was to investigate whether neuroprotection of EA pretreatment against CIRI is associated with TRPV-1 and explore the underlying mechanisms.

However, the effects and mechanisms of BBR on IL-33-induced mast cell inflammatory responses are kept unknown. To investigate these, rat peritoneal mast cells (RPMCs) were isolated from the peritoneal cavity and cultured with BBR treatment in combination IL-33 stimulation.

The photoacoustic spectrum of glucose, sucrose and honey solutions in the visible range are measured by using the single-light photoacoustic spectrometer, and are compared with the spectra from spedtrophotometry method. The spectral characteristics of the above solutions show that the spectral background intensity and spectral profile have some differences for different kinds of solutions. The spectra of the three kinds of solutions all have strong peak value at 485 and 655 nm, but the intensity ratios between the two peaks are different.

Introduction: Epidemiological studies have only recently begun to address the consequences of unpaid family work (ie., housework and child rearing) for mental health. Although research is suggestive of an association between the division of unpaid family work and psychological health, especially for women, additional research is required to clarify the conditions under which such a relationship holds.
