We and others have reported that senescence onset is accompanied by genomic instability that is evident by several defects, such as aneuploidy or erroneous mitosis features. Here, we report that these defects also appear in young cells upon oxidative insult. We provide evidence that these errors could be the consequence of oxidative stress (OS)- either exogenous or senescence-associated - overriding the spindle assembly checkpoint (SAC).

Nutrition information is becoming more urgent than ever so that consumers can make informed choices when buying food. This study aimed to investigate consumers' perceptions and behavior of the front-of-pack label (FOPL), between two specific labeling systems, the Nutri-Score and the Guideline Daily Amounts (GDA). This is a post hoc analysis of data from a previous, more extensive cross-sectional study conducted from April 2021 to June 2021.

The elderly constitute a vulnerable group for increased anxiety and poor diet during the COVID-19 pandemic. There is limited research on the levels of COVID-19-related anxiety and dietary habits including dietary supplementation practices among the elderly and very elderly in Greece. A cross-sectional survey was conducted in 364 non-institutionalized elderly (65-74 y) and very elderly (≥75 y) living in northern Greece, with the aim to investigate the use of dietary supplements and their association with other factors, particularly the COVID-19-related anxiety.

Coronary angiography and percutaneous coronary intervention (PCI) procedural details in swine are similar to those performed to humans, since their heart and coronary anatomy closely resembles. However, only a few detailed descriptions of the procedure are available, containing notable differences. We present a feasible and reproducible protocol for percutaneous coronary interventions in porcine experimental models, utilizing ultrasound-guided femoral approach.

Purpose: To investigate the effect of different combinations of laser power settings and irrigation conditions using the pulse modulation technology of Quanta™ on irrigation fluid temperature (IFT) during FURS (flexible ureteroscopy) on an in-vivo porcine model with artificial stones.

Materials And Methods: A female pig was used. Following the insertion of artificial stones (Begostone™, BEGO USA, Lincoln, RI), a K-type thermocouple was fixed to the created percutaneous access tract.

Background and aim Excessive intake of sugars and energy from drinks has been postulated to increase the risk of obesity, which may in turn be associated with mental health disorders. In addition, excessive intakes of alcohol and caffeine may co-occur with psychiatric disorders. The purpose of the present pilot study was to estimate energy, sugar, caffeine, and alcohol intakes through the consumption of drinks in patients with schizophrenia and affective disorders and assess potential differences in drink consumption between the two disorders.

Vitamin D deficiency is common even in sunny countries like Greece, especially during winter and is associated with skeletal disorders and additionally with increased risk for chronic diseases and adipose metabolic diseases such as obesity and diabetes. The purpose of this pilot study was the determination of vitamin D status in Greek adults and the investigation of possible correlation with lifestyles and somatometric characteristics. The study was conducted during winter and included 36 members (20 women and 16 men) of a university community in central Greece (latitude 39.

Objectives: To evaluate three different analgesic techniques, continuous epidural analgesia (EA), continuous intra-articular (IA) infusion analgesia and continuous femoral nerve block (FNB) in postoperative pain management, length of hospital stay (LOS), and time of patient mobilization after total knee arthroplasty (TKA).

Methods: Seventy-two patients undergoing TKA were randomly allocated into three groups according to the analgesic technique used for postoperative pain management. Group EA patients received epidural analgesia (control group), group IA received intra-articular infusion and group FNB received femoral nerve block.

Aim To investigate analgesic effect of three different regimens of combination of analgesics administered to patients undergoing laparoscopic cholecystectomy. Methods Patients undergoing laparoscopic cholecystectomy were randomly allocated to one of three groups on admission, depending of a prescribed post-operative analgesic regimen. Patients allocated to the group A received a combination of intravenous (IV) acetaminophen and intramuscular (IM) pethidine, patients in the group B received a combination of IV acetaminophen and IV parecoxib, and the patients of the group C received IV acetaminophen monotherapy.
