The last years, non-targeted fingerprinting by Fourier-transform infrared (FT-IR) spectroscopy has gained popularity as an alternative to classical gas chromatography (GC)-based methods because it may allow fast, green, non-destructive and cost-effective assessment of quality of essential oils (EOs) from single plant species. As the relevant studies for L. (bay laurel) EO are limited, the present one aimed at exploring the diagnostic potential of FT-IR fingerprinting for the identification of its botanical integrity. A reference spectroscopic dataset of 97 bay laurel EOs containing meaningful information about the intra-species variation was developed via principal component analysis (PCA). This dataset was used to train a one-class model via soft independent modelling class analogy (SIMCA). The model was challenged against commercial bay laurel and non-bay laurel EOs of non-traceable production history. Overall, the diagnostic importance of spectral bands at 3060, 1380-1360, 1150 and 1138 cm was assessed using GC-FID-MS data. The findings support the introduction of FT-IR as a green analytical technique in the quality control of these often mislabeled and/or adulterated precious products. Continuous evaluation of the model performance against newly acquired authentic EOs from all producing regions is needed to ensure validity over time.

An Integrated Pathophysiological and Clinical Perspective of the Synergistic Effects of Obesity, Hypertension, and Hyperlipidemia on Cardiovascular Health: A Systematic Review.

This review paper explores the synergistic effects of obesity, hypertension (HTN), and hyperlipidemia on cardiovascular health by integrating pathophysiological and clinical perspectives. Obesity, characterized by excessive body fat, HTN, defined by elevated blood pressure, and hyperlipidemia, indicated by high blood lipid levels, are globally prevalent conditions that significantly increase the risk of cardiovascular diseases (CVDs). The interplay between these conditions exacerbates cardiovascular risk through mechanisms such as chronic inflammation, insulin resistance, endothelial dysfunction, arterial stiffness, and atherogenesis.

Article Synopsis
- Bay laurel, a significant Mediterranean tree native to Italy, is experiencing severe damage from stem blight and internal necrosis connected to ambrosia beetle infestations in Sicily since 2021.
- Research identified a new fungal species responsible for these issues and confirmed its pathogenicity through tests on potted bay laurel plants.
- This finding marks the first report of a new pathogen linked to the invasive ambrosia beetle affecting bay laurel, adding to the understanding of plant diseases in the region.

Malan syndrome is a rare overgrowth syndrome resulting from haploinsufficiency due to heterozygous loss-of-function mutations or microdeletions of on chromosome 19 at p13.2. Phenotypic presentation can vary but is characterized by macrocephaly, long and slender body habitus, skeletal abnormalities, and intellectual disability.
