Plant Essential Oils as Healthy Functional Ingredients of Nutraceuticals and Diet Supplements: A Review
Essential oils (EOs) are mixtures of volatile molecules endowed with health-promoting biological activities that go beyond their role as aromas and natural preservatives and can be exploited to develop functional foods and diet supplements. Their composition is briefly addressed along with regulatory aspects. The potential health benefit of human diet supplementation with EOs is outlined through a review of the recent literature on available clinical trials and preclinical research concerning EOs activity towards: (1) irritable bowel syndrome; (2) inflammatory bowel disease; (3) regulation of microbiota; (4) gastroprotection; (5) hepatoprotection; (6) protection of the urinary tract and diuresis; (7) management of metabolic disorders including hyperglycemia and hyperlipidemia; (8) anti-inflammatory and pain control; (9) immunomodulation and protection from influenza; and (10) neuroprotection and modulation of mood and cognitive performance. The emerging potential in such activities of selected EOs is given focus, particularly green and black cumin, bergamot, orange, myrtle, peppermint, sage, eucalyptus, lavender, thyme, lemon balm, ginger, and garlic

Investigation on the microbiological hazards in an artisanal soft cheese produced in northern Italy and its production environment in different seasonal periods
The present study aimed at assessing the occurrence of microbiological hazards (Listeria monocytogenes, Staphylococcus aureus, Salmonella spp. and Escherichia coli O157) in an artisanal soft cheese produced in northern Italy. In the same product total bacterial count, lactic acid bacteria and Enterobacteriaceae were enumerated, and pH and water activity measured in two batches sampled in summer and winter. Samples of raw materials, environmental swabs from the production processes and cheese during 15 days of storage at 2 and 8°C as well as dynamic temperature of 2°C for 5 days and 8°C for 10 days were collected and tested. The load of total bacterial count was significantly higher in the winter batch in comparison to the summer one, with a significant increase at the end of the storage period also noticed for lactic acid bacteria. Statistical higher values of pH were registered in raw materials and end of storage in winter batch. S. aureus was con-firmed only in the winter batch within samples (n=4) of stored cheese. On plates used for E. coli O157 detection, colonies of Klebsiella pneumoniae and Klebsiella oxy-toca were isolated. The results suggest that the highest bacterial population in the winter batch was associated to a higher pH in stored cheese and a higher number of bio-logical hazards identified. Their isolation started in the maturation room suggesting this step as relevant for possible cheese contamination
The first record in Italy of Trichogramma cordubense Vargas & Cabello 1985 (Hymenoptera: Trichogrammatidae) emerging from the eggs of Lobesia botrana (Denis & Schiffermüller, 1775) (Lepidoptera: Tortricidae)
This study investigated the egg parasitoids of Lobesia botrana (Denis & Schiffermüller, 1775) feeding on Daphne gnidium L. (Malvales, Thymelaeaceae) in the San Rossore-Migliarino-Massaciuccoli Nature Reserve (Tuscany, Italy). Four species of egg parasitoids of the genus Trichogramma spp. were obtained. The parasitization rate gradually increased over the season, reaching its maximum level in September 2015, with a percentage of parasitized eggs close to 55 %. Three of the species obtained were already known as L. botrana parasitoids, whereas the finding of Trichogramma cordubense Vargas & Cabello, 1985 represents the first recording in Italy, as well as the first report of this species among the natural enemies of L. botrana
Food allergies in older people: An emerging health problem
The prevalence of food allergy (FA) is steadily increasing worldwide. Literature about FA in older people is very scarce since this is predominantly considered as a pediatric condition. However, FA can persist and/or develop across the life course. Given the growing increase in prevalence as well as their persistence, it can be expected that FA will soon represent an important issue in older people. Several age-related factors may potentially mask FA symptoms and/or mediate them in older people. These include mechanisms related to immune senescence, inflammation, and changes in gastrointestinal function as well as micronutrient deficiencies and the use of multiple medications. A multidimensional approach, taking into account the complexity in older people, it is thus important in the evaluation and management of FA during aging. The main and safest strategy in the management of FA is the allergen avoidance since their ingestion may lead to reactions ranging from mild to life-threatening. However, food restrictions should be carefully evaluated, especially in older people, for the risk of nutritional deficiencies and undernutrition
Design and construction of a new metering hot box for the in situ hygrothermal measurement in dynamic conditions of historic masonries
The main purpose of the HeLLo project is to contribute to data available on the literature on the real hygrothermal behavior of historic walls and the suitability of insulation technologies. Furthermore, it also aims at minimizing the energy simulation errors at the design phase and at improving their conservation features. In this framework, one of the preliminary activities of the study is the creation of a real in situ hot box to measure and analyze different insulation technologies applied to a real historic wall, to quantify the hygrothermal performance of a masonry building. Inside this box, 'traditional' experiments can be carried out: recording heat flux, surface temperature, and air temperatures, as well as relative humidity values through the use of a new sensing system (composed of thermocouples and temperature/relative humidity combined sensors). Within this paper, the process of development, construction, and validation of this new metering box is exhibited. The new hot box, specifically studied for historic case studies, when compared to other boxes, presents other advantages compared to previous examples, widely exemplified
Augmentation of endogenous neurosteroid synthesis alters experimental status epilepticus dynamics
Neurosteroids can modulate γ-aminobutyric acid type A receptor-mediated inhibitory
currents. Recently, we discovered that the neurosteroids progesterone,
5α-dihydroprogesterone, allopregnanolone, and pregnanolone are reduced in the cerebrospinal
fluid of patients with status epilepticus (SE). However, it is undetermined
whether neurosteroids influence SE. For this reason, first we evaluated whether the
inhibitor of adrenocortical steroid production trilostane (50 mg/kg) could modify the
levels of neurosteroids in the hippocampus and neocortex, and we found a remarkable
increase in pregnenolone, progesterone, 5α-dihydroprogesterone, and allopregnanolone
levels using liquid chromatography tandem mass spectrometry. Second, we
characterized the dynamics of SE in the presence of the varied neurosteroidal milieu
by a single intraperitoneal kainic acid (KA; 15 mg/kg) injection in trilostane-treated
rats and their controls. Convulsions started in advance in the trilostane group, already
appearing 90 minutes after the KA injection. In contrast to controls, convulsions
prevalently developed as generalized seizures with loss of posture in the trilostane
group. However, this effect was transient, and convulsions waned 2 hours before the
control group. Moreover, electrocorticographic traces of convulsions were shorter
in trilostane-treated rats, especially at the 180-minute (P < .001) and 210-minute
(P < .01) time points. These findings indicate that endogenous neurosteroids remarkably
modulate SE dynamics
Role of SP-1 in SDS-Induced Adipose Differentiation Related Protein Synthesis in Human Keratinocytes
Skin irritation is a complex phenomenon, and keratinocytes play an important role in it. We have recently characterized the expression and protective role of adipose differentiation related protein (ADRP) in skin irritation. In particular, ADRP expression is induced to recover functional cell membrane following the cell damage caused by skin irritants
Investigation on the microbiological hazards in an artisanal salami produced in Northern Italy and its production environment in different seasonal periods
In the present study, the occurrence of Listeria monocytogenes, Staphylococcus aureus, Salmonella spp. and Escherichia coli VTEC was investigated in two batches of artisanal Italian salami tested in winter and summer. Moreover, enumerations of total bacterial count, lactic acid bacteria and Enterobacteriaceae were performed as well as monitoring of water activity and pH. Samples were taken from raw materials, production process environment, semi-finished product and finished products. The results revealed an overall increase of total bacterial count and lactic acid bacteria during the ripening period, along with a decrease of Enterobacteriaceae, pH and water activity. No significant difference was observed between the two batches. The enterobacterial load appeared to decrease during the maturation period mainly due to a decrease in pH and water activity below the limits that allow the growth of these bacteria. E. coli VTEC, Salmonella spp. or L. monocytogenes were not detected in both winter and summer batches. However, Klebsiella pneumoniae was detected in both summer and winter products. Except for one isolate, no biological hazards were detected in the finished salami, proving the efficacy of the ripening period in controlling the occurrence of microbiological hazard in ripened salami. Further studies are required to assess the virulence potential of the Klebsiella pneumoniae isolates
Profile of deglutition speech evaluation in an intensive care unit
The combination of an increase in long-term survival and the availability
of a relatively sensitive parathyroid hormone (PTH) assay has led to
an increasing incidence of hyperparathyroidism (HPT) diagnosis in patients
on regular dialysis treatment (RDT). Hitherto the diagnosis has been
based on biochemical data and clinical grounds, as parathyroid (PT) imaging
is limited in accuracy, reproducibility, safety and invasiveness [1, 2].
Today, 201TI and 99mTc subtraction imaging (sq, high resolution ultrasonography
(US) and up-to-date computed tomography (CT) have been proposed
as sensitive and specific tests for primary HPT imaging [4-7]. The
aim of the present study was to assess on a group of patients on RDT the
accuracy of these methods in relation to the degree of HP
