Optimizing Green Extraction Methods for Maximizing the Biological Potential of Dandelion, Milk Thistle, and Chamomile Seed Extracts.

This study investigates the underutilized potential of agri-crops from the family by employing sustainable and green technologies (supercritical fluid, ultrasound, and Soxhlet extractions) to enhance the recovery of bioactive compounds. A total of 21 extracts from native and waste seeds of dandelion, milk thistle, and chamomile were systematically compared utilizing a combination of solvents (supercritical CO and absolute or aqueous ethanol). Supercritical CO extraction yielded up to 281 mg/g of oils from native seeds, while conventional techniques with ethanol recovered an additional 142 mg/g of extracts from waste seeds.

An Eco-Friendly Supercritical CO Recovery of Value-Added Extracts from Leaves.

An eco-friendly approach towards the recovery of value-added extracts from olive tree leaves with the aid of supercritical CO at 30 MPa was carried out. The impact of extraction temperature (35-90 °C) and presence of co-solvents (ethanol, water, and aqueous ethanol) on the total phenolic, flavonoid, and pigment content, as well as oleuropein, hydroxytyrosol, tyrosol, and α-tocopherol content was determined. In addition, the antioxidant activity of extracts from tree leaves using DPPH, ABTS, and CUPRAC assays was investigated.

Quality of Life of Patients with Oral Squamous Cell Carcinoma.

Background: Oral squamous cell carcinoma (OSCC) has numerous physical, psychosocial and financial implications, which significantly affect patients' quality of life. We aimed to determine the health-related quality of life (HRQoL) and identify quality of life (QoL) predictors in patients with OSCC.

Methods: We included 64 consecutive patients aged 40 to 80 yr treated for OSCC from Jan to Dec 2021.

Cornstarch aerogels with thymol, citronellol, carvacrol, and eugenol prepared by supercritical CO- assisted techniques for potential biomedical applications.

This study focuses on the development of bioactive materials using environmentally friendly techniques, renewable, biocompatible, and biodegradable polysaccharide, as well as natural bioactive compounds (NBCs) found in plant extracts. First, cornstarch aerogels with a porosity of 86 % and a specific surface area of 225 m/g were produced via supercritical CO- assisted drying. Further, thymol, citronellol, carvacrol, and eugenol were incorporated into the aerogels by supercritical CO- assisted impregnation, which allowed variation in loadings of NBCs (12.

Assessment of the Frequency, Causes, Degree and Consequences of Violence against Health Workers in Psychiatric Institutions.

(1) Background: The prevalence of workplace violence within the health sector varies between 50 and 88%. Depending on the health care environment, the percentages mentioned can be much higher. (2) The aim of this study was to determine the prevalence, characteristics, factors, and consequences of violence against healthcare workers (physicians, nurses, and technicians) in psychiatric institutions in the Republic of Serbia.
