Increased leptin/leptin receptor pathway affects systemic and airway inflammation in COPD former smokers
2011
Andreina Bruno1, Marinella Alessi2, Simona Soresi2, Anna Bonanno1, Loredana Riccobono1, Angela Marina Montalbano1, Giusy Daniela Albano1, Mark Gjomarkaj1, Mirella Profita11Institute of Biomedicine and Molecular Immunology, Italian National Research Council, Palermo, Italy; 2Dipartimento Biomedico di Biomedicina Interna e Specialistica, University Palermo, ItalyBackground: Leptin, a hormone produced mainly by adipose tissue, regulates food intake and energy expenditure. It is involved in inflammatory diseases such as chronic obstructive pulmonary disease (COPD) and its deficiency is associated with increased susceptibility to the infection. The leptin receptor is expressed in the lung and in…
Skin response to a carcinogen involves the xenobiotic receptor pregnane X receptor.
2015
Skin is in daily contact with potentially harmful molecules from the environment such as cigarette smoke, automobile emissions, industrial soot and groundwater. Pregnane X receptor (PXR) is a transcription factor expressed in liver and intestine that is activated by xenobiotic chemicals including drugs and environmental pollutants. Topical application of the tumor initiator 7,12-dimethylbenz(a)anthracene (DMBA) enhances Pxr, Cyp1a1, Cyp1b1 and Cyp3a11, but not Ahr expression in the skin. Surprisingly, DMBA-induced Pxr upregulation is largely impaired in Langerin(+) cell-depleted skin, suggesting that DMBA mainly triggers Pxr in Langerin(+) cells. Furthermore, PXR deficiency protects from DN…
Male breast cancer: Reconstructive surgery
2020
The conventional treatment for male breast cancer consists of modified radical mastectomy with axillary sentinel node biopsy and/or axillary lymph node dissection in case of lymph node-positive disease. However, breast-conserving surgery (BCS) is gaining popularity also among men. In both cases, surgery leaves an aesthetic disfigurement that impacts patient well-being and quality of life. Thus, even if male breast has a different social and emotional role than female’s one, male breast reconstruction deserves the same importance. The aim of this chapter is to give a comprehensive review on latest indications and strategies for the post-oncological reconstructive surgery of the male breast.
An exploratory study of two Caco-2 cell models for oral absorption: A report on their within-laboratory and between-laboratory variability, and their…
2010
In 2005, the European Centre for the Validation of Alternative Methods (ECVAM) sponsored a study aimed at evaluating the reproducibility (between-laboratory and within-laboratory variability) and the predictive capacity of two in vitro cellular systems — the Caco-2/ATCC parental cell line and the Caco-2/TC7 clone — for estimating the oral fraction absorbed (Fa) in humans. Two laboratories, both of which had experience with Caco-2 cultures, participated in the study. Ten test chemicals with documented in vivo oral absorption data were selected. Atenolol, cimetidine and propranolol were included as reference compounds for low, medium and high intestinal absorption, respectively. Transport ex…

Relationship between Skin Temperature Variation and Muscle Damage Markers after a Marathon Performed in a Hot Environmental Condition
2021
This study aimed to assess the effect of a marathon running at a hot environmental temperature on the baseline skin temperature (Tsk) of the posterior day and to analyze the relationship between Tsk response and muscle damage markers variation. The Tsk, creatine kinase, and lactate dehydrogenase of 16 marathon runners were assessed four times before (15 days and 45 min) and after (24 h and 6 days) a marathon in a hot environment (thermal stress index = 28.3 ± 3.3 °C and humidity ~81%). The Tsk of thirteen different body regions of both right and left lower limbs were analyzed. Higher values after the marathon were observed than 45 min before in creatine kinase (174.3 ± 136.4 UI/L <
P01-92 - Early Changes are Associated with late Changes of BDNF Serum Levels in Inpatients with Major Depression During Short-term Antidepressant Tre…
2010
ObjectivesMean BDNF serum concentration is lower in patients with major depression (MD) as compared to healthy controls. BDNF increases during the course of antidepressant treatment. This increase has been associated with symptom amelioration. The aim of this study was to analyse the relation between early and late BDNF changes during antidepressant treatment.MethodsForty-six patients with MD according to DSM-IV were included for this study. Patients were treated as clinically indicated. Depression severity was assessed by HAMD-17 by trained raters from baseline to week 6 in weekly intervals. Serum at each visit (baseline, V1-V6) was obtained from whole blood after centrifugation with 1.000…
Simvastatin in vitiligo: an update with recent review of the literature.
2021
Patients with vitiligo often seek medical attention, as it diminishes their quality of life resulting in significant morbidity. Several topical and systemic therapies are in vogue targeting the immunological aspect of this disease, but results are often unsatisfactory, and complete cure remains elusive. Recently, simvastatin, a 3-hydroxy-3-methylyglutaryl-coenzyme A (HMG-CoA) reductase inhibitor, is being evaluated for vitiligo management because of its multimodal action, easy availability, and low cost. The proposed multimodal actions range from anti-inflammatory, antioxidant, to immunomodulatory properties which may be of therapeutic benefit in vitiligo patients. The authors intend to eva…
Sentinel Node Identification in Melanoma: Current Clinical Impact, New Emerging SPECT Radiotracers and Technological Advancements. An Update of the L…
2020
Background: Melanoma is the most lethal skin cancer with a mortality rate of 262 cases per 100.000 cases. The sentinel lymph node (SLN) is the first lymph node draining the tumor. SLN biopsy is a widely accepted procedure in the clinical setting since it provides important prognostic information, which helps patient management, and avoids the side effects of complete lymph node dissection. The rationale of identifying and removing the SLN relies on the low probability of subsequent metastatic nodes in case of a negative histological exam performed in the SLN. Discussion: Recently, new analytical approaches, based on the evaluation of scintigraphic images are also exploring the possibility …
