This work was initiated to develop a simple, quick, and reliable UHPLC-PDA-MS method identify chemical markers for authentication compare fruit samples of four elder species, Sambucus nigra, S. ebulus, canadensis, cerulea. The UHPLC showed an adequate separation 11 compounds including anthocyanins, phenolic acids, flavonoids in berries the species. Quantification, detection limits, precision, a...

BACKGROUND Gentamicin (GM) is used as antibiotic for Gram-negative infections, but its administration is limited due to a side-effect of nephrotoxicity. It was attempted to investigate the effect of Althaea officinalis flower extract (AOFE) against nephrotoxicity induced by GM in male rats. METHODS 30-year-old male Wistar rats were divided into five groups. Group 1 as a negative control group...

Variable selection is an essential part of any statistical analysis and yet has been somewhat neglected in the context of longitudinal data analysis. In this article, we propose a generalized version of Mallows's C(p) (GC(p)) suitable for use with both parametric and nonparametric models. GC(p) provides an estimate of a measure of model's adequacy for prediction. We examine its performance with...

Pityriasis rosea is a common erythematosquamous eruption, typically presenting along the cleavage lines of the skin. A wide spectrum of atypical manifestations may challenge even the most experienced physician. Here we report a rare case of a suberythrodermic pityriasis rosea with gigantic plaques after an influenza vaccination, and we discuss the possible triggers of atypical manifestations of...

Imatinib mesylate (Gleevec™, STI571), a selective inhibitor of BCR-ABL, c-Kit, and platelet-derived factor receptor, has been used to treat chronic myelogenous leukemia (CML) and gastrointestinal stromal tumors. Although its use has been associated with various adverse cutaneous reactions, pityriasis rosea-like drug eruptions are rare. Here, we report a case of pityriasis rosea-like drug erupti...

The in vitro antibacterial activities of 29 traditional medicinal plants used in respiratory ailments were assessed on multidrug resistant Gram-positive and Gram-negative bacteria isolated from the sore throat patients and two reference strains. The methanolic, n-hexane, and aqueous extracts were screened by the agar well diffusion assay. Bioactive fractions of effective extracts were identifie...

In recent years, several studies have shown that Rhodiola rosea can enhance cellular immunity and humoral immune function in mice, and thus, it has become a research hotspot. However, its underlying mechanism of action has remained elusive. The present study investigated whether Rhodiola rosea was able to downregulate the expression of tumor necrosis factor-α-inducible protein 8-like 2 (TIPE2),...
