Adipobiology of inflammation

Abstract: Besides its importance for glucose, lipid and energy metabolism, the present paradigm defines adipose tissue as thebody's largest endocrine and paracrine organ. Accumulating evidence demonstrates that adipose tissue cells synthesize and release a large number of signaling proteins collectively termed adipokines. Adipokines regulate a broad spectrum of biological processes, with inflammation being a key example. This defines a new field of study: adipobiology of inflammation. Herewe shalldance round it, supposing that the pathogenesis of inflammation-related diseases such as atherosclerosis, thyroid-associated ophthalmopathy, inflammatory bowel diseases, and breast cancer may be influenced by competing stimulatory and inhibitory effects mediated by adipokines. This concept may reveal new tools for the development of adipopharmacology of inflammatory disease. Biomedical Reviews 2005; 16: 83-88.

Wine as a medicine in ancient times

Abstract: The history of wine use as a medicine dates back to antiquity. However, it has been rediscovered and reliably confirmed by current medical research. It is believed that wine is among the first documented remedies known and used by humans dating back to a period before 5000 BC. Preserved to date evidence of the medical use of wine in ancient times is very limited and is related to the development of different cultures and ancient civilizations. The article chronicles the more important periods of the history of the use of wine for medical (healing and prophylactic) purposes. The first evidence dates back to the time of the Mesopotamian culture, when the world's oldest Sumerian Pharmacopoeia - clay tiles, some of which contain wine prescriptions for therapy, was created. The next important documentary evidence is found in the Sino-Tibetan Pharmacopoeia, the Egyptian Medical Papyri, the Bible, the Sacred Book of the Jews Talmud , and the ancient Indian medical texts of Ayurveda. In ancient Greece, the first evidence of the healing effects of wine is found in the two poems of Homer Iliad and Odyssey . With the development of medical knowledge at the time of Hippocrates, the therapeutic use of wine expanded. Hippocrates included wine in the diet of almost all diseases, especially during the recovery period. Afterwards, the principles of wine therapy continued to be topical, although they were the subject of a heated debate during the Greco-Roman period, Galen's era, and even the Byzantine era, when the influence of Arab medicine began to manifest itself more and more.

Adipobiology of stem cell-based therapy: secretome insight

Abstract: Stem from the promise of stem cells therapeutic potential for a number of diseases, the regenerative medicine is reaching enthusiastic proportions nowadays. Current therapies include drug treatment, lifestyle modification, organ transplantation, RNA interference “breakthrough technology”, and stem cell-based therapy. Research on stem cells is a multiplex challenge provoking both the attention and the confusion of biologists, biotechnologists, medical specialists, and politicians. By integrating various approaches of transcriptomics, proteomics and metabolomics, current adipobiology has identified more than 100 secretory proteins that are produced by the adipose tissue. These proteins designated adipokines include growth factors, cytokines, chemokines, neuropeptides and hypothalamic hormones/releasing factors. In addition, the adipose tissue’s secretome contains steroid hormones, free fatty acids, prostaglandins, and endocannabinoinds. Moreover, adipose tissue is the source of adipose-derived stem cells (ADSC). Current interest in the ADSC stems from their multilineage differentiation potential, and ease of derivation in larger quantities using less invasive methods, compared with other stem cell types. The possible benefits of ADSC-based therapy may be mediated via cell proliferation/differentiation and/or paracrine mechanisms. The present review, focusing on adipose tissue secretory activity, also highlights the possible implication of ADSC in the therapy of various disorders, particularly neurodegenerative diseases, myocardial infarction and stroke, along with gut and liver diseases.

Minimising radiation exposure to the surgeon in minimally invasive spine surgeries: A systematic review of 15 studies.

Abstract: Background Intraoperative imaging in minimally invasive spinal surgeries is associated with significant radiation exposure to surgeons, which overtime can lead to serious health hazards including malignancy. In this study, the authors conducted a systematic review to evaluate the efficacy of navigation assisted fluoroscopy methods on radiation exposure to the surgeon in minimally invasive spine surgeries, percutaneous endoscopic lumbar discectomy/percutaneous endoscopic transforaminal discectomy versus minimally invasive spine transforaminal lumbar interbody fusion (PELD/PETD versus MIS-TLIF). Methods A systematic literature search was conducted using PUBMED/MEDLINE on 20th July, 2020. Inclusion criteria were applied according to study design, surgical technique, spinal region, and language. Data extracted included lumbar segment, average operation time (min), fluoroscopic time (s), and radiation dose (μSV), efficacy of modified navigation versus conventional techniques; on reducing operation, fluoroscopy times and effective radiation dose. Results Fifteen studies (ten prospectives, and five retrospectives) were included for quantitative analysis. PELD recorded a shorter operation time (by 126.3 min, p Discussion This systematic literature review showed that although navigation assisted fluoroscopy techniques are superior to conventional methods in minimising radiation exposure, lack of statistical significance warrants future randomised controlled trials, to solidify their efficacy in reducing radiation related hazards.

Digital analysis of teeth treated with the Hall technique

Abstract: INTRODUCTION: The information about digital examination provided by the scientific literature is quite insufficient. Therefore, digital examination of the occlusion is an object of analysis not only in Bulgaria but in other countries as well. No evidence for digital occlusal analysis on Hall-crowned teeth was found in the prosthetic part of the pediatric dentistry. AIM: The aim of this article is to conduct a study on the occlusal balance with T-scan after treatment with preformed metal crowns (PMCs) using the Hall technique. MATERIALS AND METHODS: Object of the clinical study were 50 crowned primary teeth. Unit of observation with the T-scan 8 system were occlusal articulation relationships in primary and early mixed dentition after the Hall technique. RESULTS: The results confirmed equal occlusal relationships in both sides – the crowned teeth compared with the symmetrical natural teeth. The occlusal contacts were with a similar value of the summary masticatory force compared with the control group of natural teeth. CONCLUSION: The received data confirmed that the restoration of decayed teeth with preformed metal crowns maintained the occlusal harmony in the dentition.
