Fibrin scaffolds physically and chemically modified to be stiffer or have higher concentrations of calcium and phosphate ions were hypothesized to enhance osteogenic differentiation compared to control fibrin scaffolds. Treatments during coagulation resulted in six scaffold types for comparison: whole blood controls, red blood cell lysis buffer, calcium chloride, calcium hydrogen phosphate, vacuum, and mechanical compression. Based on the results, fibrin supplemented with granules of calcium hydrogen phosphate (CaHPO4) was determined to be the most suitable formulation of those examined. Using calcium phosphate resulted in a fibrin scaffold that coagulated faster (p = 0.022), had a rougher surface, higher stiffness, and desirable properties for practical use during surgical operations and scaffolds used in bone tissue engineering. Further, osteogenic differentiation was enhanced on scaffolds treated with calcium phosphate. In addition, fibrin scaffolds treated with RBC lysis buffer were also stiffer than untreated controls. These results are partly explained by ASC attachment and fibrin polymerization during coagulation.","PeriodicalId":148803,"journal":{"name":"International Journal of Regenerative Medicine","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122713660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The primary aim of these studies was to analyse in vitro ASC migration in varying concentrations of growth factors derived from the platelet-rich fraction of centrifuged plasma, the so-called platelet-rich plasma (PRP). ASCs were hypothesized to migrate at a faster velocity with increasing PRP concentrations. Whole blood was collected with a sodium citrate anticoagulant and subjected to two centrifugations. The first slower spin was to remove red blood cells to collect plasma, and the second faster spin was to collect the fraction with a high platelet concentration. Platelet concentration increased 3.5-fold compared to plasma, within the prescribed therapeutic range. For long-term culture of ASCs, DMEM supplemented with no more than 20% was necessary to maintain cell viability. ASC proliferation rate in PRP-supplemented media was comparable to that in fetal bovine serum (FBS), a standard cell culture media supplement. In addition, the velocity of ASC migration increased in cultures supplemented with 10%, 20% or 30% PRP. Generally, PRP was determined to be a media supplement with similar effects as FBS, potentially making it a suitable substitute for in vitro expansion of ASC populations. These results are likely partly explained by similarities in growth factor concentrations and their effects. Further characterization of PRP will be necessary to tease out the specific growth factor(s) responsible for the increase in swine ASC migration.","PeriodicalId":148803,"journal":{"name":"International Journal of Regenerative Medicine","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130391514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Entropy is a well-applied concept in many fields, including physics, chemistry, biology, and medicine. Various perspectives have been used to describe the concept, creating confusion and misconceptions. In chemical and biochemical reactions, entropy plays a significant role in the directionality and spontaneity of the reactions. Potential energy can be used to better understand the concept of entropy. Potential energy represents order, while entropy represents disorder; therefore, they are inversely proportional and intimately linked. Molecules with high potential usually have rich sets of functions and information, which is due to the enrichment of their constitutions, configurations, and conformations. In molecules with low potential, there are greater vibrational, rotational, and translational motions associated with decreased order in their constitution, configuration, and conformation. Distribution of electronic charge changes in macromolecules over time, increasing the rotation of side-chain residues and thus increasing entropy and affecting potential in terms of structure, function, and information. Entropy can thus be defined as a state of spontaneous change, bound to time and constantly increasing, which causes structural changes in the form of constitution, configuration, and conformation, and functional changes in the form of the ability to do work as well as informational changes in the form of the transmission of commands.","PeriodicalId":148803,"journal":{"name":"International Journal of Regenerative Medicine","volume":"201 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116168063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The fibrous tissue constitutes a natural barrier to the progression of the fistula repair process and represents the major cause of non-healing and chronicization even in a context of proper vascularization. The microfractured autologous adipose graft allows to provide the tissues involved in the fibrotic process with a regenerative stimulus by MSCs (mesenchymal stem cells) contained in adipose clusters of 0.3 mm. In this context, MSCs are able to secrete cytokines with antibiotic, antifibrotic, angiogenic and analgesic effects. The micro-fragmentation technique guarantees a high regenerative effect, as the MSCs are not isolated enzymatically with the simultaneous destruction of the adipose tissue. The micro-fragmentation allows the maintainance of the structure of the adipose cluster including microvessels and allows it to amplify by 6000 times the active surface that exposes the MSCs. Our experience with the mechanical microfracturing method of lipoaspirate consists of 41 treatments. In 7 cases the graft was performed due to the presence of a non-healing cutaneous fistula, which lasted from 128 to 243 days. In 6 cases we achieved immediate repair and closure of the fistula while in one case the procedure failed. The purpose of the paper is to describe in detail our experience by an accurate description of the implemented method of the used device accompanied by the document with adequate photographic documentation.","PeriodicalId":148803,"journal":{"name":"International Journal of Regenerative Medicine","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125422334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The correct identification of the anatomy of the main and secondary fistula tracts and the individuation of abscess cavities are fundamental for correct treatment. Intraoperative endoscopic evaluation and the complete destruction of the fistula pathway can be achieved through video-assisted anal fistula treatment (VAAFT). Furthermore, the injection of human autologous Microfractured Adipose Tissue (MFAT) processed by a Lipogems® device can be used as both a bulking agent and a regenerative technique.\u0000Methods: A combined approach of VAAFT plus Microfractured Adipose Tissue Graft (MFAT) is proposed in order to treat recurrent and complex fistula in ano.\u0000Results: Three cases treated with a combination of VAAFT and MFAT grafts are described. All cases had undergone multiple interventions at the perianal level over a period ranging from 1 to 15 years. One case certainly failed due to poor patient compliance, but in the remaining two cases, the patients made a complete recovery with the disappearance of symptoms over a follow-up period of one to two years.\u0000Conclusion: The combination of video-assisted anal fistula treatment and injection of human autologous microfractured adipose tissue may be a valid, safe and feasible therapeutic option. MFAT injections are more effective in promoting tissue regeneration than simply “filling” the fistula tract and are common practice also in the treatment of Crohn’s Disease due to the immunomodulatory power of mesenchymal cells.","PeriodicalId":148803,"journal":{"name":"International Journal of Regenerative Medicine","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127710215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As there is no perfect treatment for management, Gplife has thought of and developed a product that is found to be effective in the management of insulin-dependent diabetes. After 60 days of evaluation of cases, it is observed that fasting blood glucose was reduced by 62.25%, postprandial glucose levels were reduced by 62.37%, HBA1C levels were reduced by 39.57%, C Peptide levels were increased by 26.67%, also the external insulin injection requirement of the patient’s decreased by 88.57%. This case study gives an overview of the current understanding of the disease and the efficacy of advance diabetic support products in insulin-dependent diabetes. It is evident that the said product further helps to reduce insulin and OHA doses for the management of insulin-dependent diabetes.
