Integration of transcriptomic and metabolomic analysis unveils the response mechanism of sugar metabolism in Cyclocarya paliurus seedlings subjected to PEG-induced drought stress.

Cyclocarya paliurus (Batal.) Iljinskaja is a multiple function tree species used for functional food and valued timber production. Carbohydrates, especially water-soluble carbohydrates, play an important role in osmotic protection, signal transduction and carbon storage.

Factors Associated With Stress Urinary Incontinence and Diastasis of Rectus Abdominis in Women at 6-8 Weeks Postpartum.

Importance: In recent years, pelvic-abdominal dynamics has become a research topic in the field of pelvic floor dysfunction (PFD), and the relationship between diastasis of the rectus abdominis (DRA) and stress urinary incontinence (SUI) has been controversial. The study is helpful to further strengthen perinatal education, accurately identify the risk factors of SUI and DRA, and improve the quality of life of puerperae.

Objective: This study aimed to investigate the association of SUI and DRA in women with PFD as measured by vaginal palpation or pelvic floor biofeedback machine testing.

Three-dimensional MnO porous hollow microspheres for enhanced activity as ozonation catalysts in degradation of bisphenol A.

Three-dimensional (3D) MnO porous hollow microspheres (δ- and α- MnO PHMSs), with high adsorption and catalytic ozonation performance, were synthesized by a self-template (MnCO microspheres) process at room temperature. The synthesized MnO PHMSs were characterized by X-ray diffraction (XRD), scanning electronic microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and Brunauer-Emmett-Teller (BET) surface area. The results showed that PHMSs exhibit the excellent adsorption ability and catalytic activity owning to their hollow spherical structure, mesoporous shell and well-defined interior voids, leading to the strong adsorption for bisphenol A (BPA) and the retention of O molecules on catalyst.

[Expression of DUOX2 in psoriasis and atopic dermatitis lesion].

Objective: To investigate the expression of dual oxidase 2 (DUOX2) in psoriasis vulgaris lesions, atopic dermatitis (AD) lesions and normal skin and its role in cutaneous anti-inflammation.

Methods: Tissue samples were harvested from psoriasis lesion area, psoriasis non-lesion area, AD lesion area and AD non-lesion area, as well as normal skin, the expression level of DUOX2 protein was detected by immunohistochemical staining. The mRNA level of DUOX2 was detected by reverse transcription polymerase chain reaction (RT-PCR) analysis.

[The protective effects of sodium selenite and aloin against ultraviolet A radiation].

Objective: To investigate the protective effects of sodium selenite and aloin against ultraviolet A (UVA) radiation on the dermal fibroblasts including the suppression of proliferation, oxidative damage and collagen synthesis.

Methods: Human dermal fibroblasts were divided into the negative control group, the positive control UVA radiation group, the sodium selenite treatment plus UVA radiation group and the aloin treatment plus UVA radiation group, which were incubated with sodium selenite or aloin and irradiated with 5 J/cm2 UVA respectively. The MTT spectrophotometry and biochemical assay were used to determine the proliferation, collagen level and the SOD and GSH-Px activity of the fibroblast cells after radiation.
