Immediate hypersensitivity to latex is now well known. Contact urticaria is the most common manifestation, sometimes associated with rhinitis, asthma or a generalized rash. Atopy and frequent contact with latex favor sensitization. Anaphylactic shock is to be feared in sensitized patients during contact with latex, especially in peroperative situations (latex surgical gloves), as in the 12 cases reported. The shock is unusual in its delayed appearance and its progressive course. Positive skin tests to latex, the presence of specific IgE antibodies and negative skin tests to anesthetics confirm the diagnosis. However, the latex allergen has not yet been identified. Due to the increasing use of protective rubber (gloves, condoms, etc), the frequency of latex sensitization should increase. Systematic screening during history taking will be important before treatment.

The precision in electron holography studies on electrostatic and magnetic fields depends on the image quality of an electron hologram. Enhancing the image quality of electron holograms is essential for the comprehensive analysis of weak electromagnetic fields; however, extended electron beam irradiation can lead to undesirable radiation damage and contamination. Recent studies have demonstrated that noise reduction using the wavelet hidden Markov model (WHMM) can improve the precision of phase analysis for limited thin-foiled crystals.

Oxazolidine is a new category of stimuli-chromic compounds that has unique intelligent behaviors such as halochromism, hydrochromism, solvatochromism, and ionochromism, all of which have potential applications for designing and constructing chemosensors by using functionalized-polymer nanocarriers. Here, the poly(MMA--HEMA) based nanoparticles were synthesized by emulsion copolymerizing methyl methacrylate (MMA) and 2-hydroxyethyl methacrylate (HEMA) in different copolymer compositions. The poly(MMA--HEMA) based nanoparticles were modified physically with tertiary amine-functionalized oxazolidine (as an intelligent pH-responsive organic dye) to prepare halochromic latex nanoparticles.

Ethnopharmacological Relevance: Schisandrachinensis, a traditional functional Chinese medicine, is known for its ability to tonify the kidneys, calm the heart, and tranquilize the mind. Recent pharmacological research has demonstrated its anti-inflammatory and neuroprotective effects.
Aim Of The Study: We had previously demonstrated that Schisandra chinensis lignans (SCL) promote microglia polarization to M2 phenotype via targeting cannabinoid receptor type-2 (CB2R) to exert antidepressant effects.
