Contribution of ghrelin to functional gastrointestinal disorders' pathogenesis

World Journal of Gastroenterology 2019年第5期25卷 539-551页

作者： Tilemachos Koutouratsas Theodora Kalli georgios Karamanolis Maria Gazouli Department of Basic Medical Science Laboratory of Biology School of Medicine University of Athens Gastroenterology Department Larnaca General Hospital Gastroenterology Unit 2nd Department of Surgery "Aretaieio"University Hospital School of Medicine University of Athens

Functional gastrointestinal disorders(FGID) are heterogeneous disorders with a variety of clinical manifestations, primarily defined by signs and symptoms rather than a definite underlying cause. Their pathophysiology remains obscure and, although it is expected to differ according to the specific FGID, disruptions in the brain-gut axis are now thought to be a common denominator in their pathogenesis. The hormone ghrelin is an important component of this axis,exerting a wide repertoire of physiological actions, including regulation of gastrointestinal motility and protection of mucosal tissue. Ghrelin's gene shows genetic polymorphism, while its protein product undergoes complex regulation and metabolism in the human body. Numerous studies have studied ghrelin's relation to the emergence of FGIDs, its potential value as an index of disease severity and as a predictive marker for symptom relief during attempted treatment. Despite the mixed results currently available in scientific literature, the plethora of statistically significant findings shows that disruptions in ghrelin genetics and expression are plausibly related to FGID pathogenesis. The aim of this paper is to review current literature studying these associations, in an effort to uncover certain patterns of alterations in both genetics and expression, which could delineate its true contribution to FGID emergence, either as a causative agent or as a pathogenetic intermediate.

Acute coronary syndrome after infliximab therapy in a patient with Crohn’s disease

引用

World Journal of Gastroenterology 2006年第38期12卷 6235-6238页

Infliximab is a potent anti-TNF antibody, which is used with great success in Crohn’s disease patients. Since its release in clinical practice, several adverse reactions have been observed. The interest in possible consequences of its administration is still high because of the recent introduction of the drug for the long-term maintenance therapy of refractory luminal and fistulizing Crohn’s disease. We present a case of acute coronary syndrome (non-STEMI) in a patient with corticoid resistant Crohn’s disease after his first dose of infliximab. By reviewing the scant articles that exist in the literature on this topic we made an effort to delineate the possible mechanisms of this phenomenon.

Lingual Nerve Entrapment in Muscular and Osseous Structures

引用

International Journal of Oral Science 2010年第4期2卷 181-189页

作者： Maria Piagkou Theano Demesticha Giannoulis Piagkos Androutsos georgios Skandalakis Panagiotis Department of Anatomy School of MedicineFaculty of Health SciencesUniversity of Athens

Running through the infratemporal fossa is the lingual nerve （i.e. the third branch of the posterior trunk of the mandibular nerve）. Due to its location, there are various anatomic structures that might entrap and potentially compress the lingual nerve. These anatomical sites of entrapment are：（a） the partially or completely ossified pterygospinous or pterygoalar ligaments; （b） the large lamina of the lateral plate of the pterygoid process; and （c） the medial fibers of the anterior region of the lateral pterygoid muscle. Due to the connection between these nerve and anatomic structures, a contraction of the lateral pterygoid muscle, for example, might cause a compression of the lingual nerve. Any variations in the course of the lingual nerve can be of clinical significance to surgeons and neurologists because of the significant complications that might occur. To name a few of such complications, lingual nerve entrapment can lead to：（a） numbness, hypoesthesia or even anesthesia of the tongue’s mucous glands; （b） anesthesia and loss of taste in the anterior two-thirds of the tongue; （c） anesthesia of the lingual gums; and （d） pain related to speech articulation disorder. Dentists should, therefore, be alert to possible signs of neurovascular compression in regions where the lingual nerve is distributed.

Journal of Wuhan University of Technology(Materials Science) 2017年第4期32卷 753-759页

作者：丁磊 WANG Lixiong georgios Kokogiannakis Lü Yajun 周卫兵 School of Architecture Tianjin University Sustainable Buildings Research Centre University of Wollongong School of Architecture North China University of Water Resources and Electric Power School of Materials Science and Engineering Wuhan University of Technology

In order to obtain the suitable phase change material（PCM） with low phase change temperature and improve its heat transfer rate, experimental investigation was conducted. Firstly, different mass ratios of lauric acid（LA） and stearic acid（SA） eutectic mixtures were prepared and characterized by differential scanning calorimetry（DSC）. Then, the performance of eutectic mixture during charging process under different fin widths in vertical condition, and performance during charging and discharging processes under different inlet temperature heat transfer fluid（HTF） in horizontal condition were investigated, respectively. The results revealed that the LA-SA eutectic mixture had the suitable phase change temperature and desired latent heat for low-temperature water floor heating system. Wide fins and high inlet temperature HTF significantly enhanced the transfer rate and decreased the melting time.

作者： georgios Labiris Eirini-Kanella Panagiotopoulou Vassilios P.Kozoboli Department of Ophthalmology University Hospital of AlexandroupolisDraganaAlexandroupolis 68 100Greece Eye Institute of Thrace Alexandroupolis 68100Greece

A systematic review of the recent literature regarding a series of ocular diseases involved in European telemedicine projects was performed based on the Pub Med, Google Scholar and Springer databases in June 2017. Literature review returned 44 eligible studies; among them, emergency ophthalmology, diabetic retinopathy, glaucoma, age-related macular disease, cataract and retinopathy of prematurity. The majority of studies indicate teleophthalmology as a valid, reliable and cost-efficient method for care-provision in ophthalmology patients which delivers comparable outcomes to the traditional examination methods.
