An optimized method for DNA extraction from materials available for forensic medical examination is proposed based on partial combination of two procedures, phenol-chloroform extraction and sorption. Such a combination provided a basis for the development of a protocol making use of the advantages of both procedures and free of drawbacks of either of them. This relatively simple and rapid method uses no reagents having adverse effect on human organism. Also, it excludes the use of substances interfering with polymerase chain reaction (PCR) and thereby reduces the risk of DNA loss. This makes it suitable for the work with objects having very low DNA content. The DNA specimens obtained with the help of the proposed technique are fit for prolonged storage.

Background: Environmental allergens induce the release of danger signals from the airway epithelium that trigger type 2 immune responses and promote airway inflammation.
Objective: To investigate the role of allergen-stimulated P2Y receptor activation in regulating ATP, IL-33 and DNA release by human bronchial epithelial (hBE) cells and mouse airways.
Methods: hBE cells were exposed to Alternaria alternata extract and secretion of ATP, IL-33 and DNA were studied in vitro.

Pityriasis rosea (PR) is a self-limited exanthem associated with the endogenous systemic reactivation of human herpesvirus (HHV)-6 and HHV-7. The disease typically begins with a single erythematous patch on the trunk (herald patch), followed by a secondary eruption of smaller papulosquamous lesions. Rarely, the herald patch may be the only cutaneous manifestation of PR.

This study explores the effects of plant compounds on human papillomavirus (HPV)-induced W12 cervical precancer cells and bioelectric signaling. The aim is to identify effective phytochemicals, both individually and in combination, that can prevent and treat HPV infection and HPV associated cervical cancer. Phytochemicals were tested using growth inhibition, combination, gene expression, RT PCR, and molecular docking assays.

In this work, extracts from the pulp, peel, and seed of were obtained via lyophilization and oven drying. Bromatological analyses were performed to investigate variabilities in the nutritional content of fruits after nine post-harvest days. The phytochemical content of fruits was assessed by gas chromatography flame ionization detector (GC-FID), and their biological performance was studied using antibacterial and antioxidant assays (DPPH and ABTS) and toxicity models.
