Bioprinting with live cells

Tissue engineering is an emerging multidisciplinary field to regenerate damaged or diseased tissues and organs. Traditional tissue engineering strategies involve seeding cells into porous scaffolds to regenerate tissues or organs. However, there are still some challenges such as difficulty in seeding different type of cells spatially into a scaffold, limited oxygen and nutrient delivery and removal of metabolic waste from scaffold and weak cell-adhesion to scaffold material need to be overcome for clinically successful results. Because of those challenges, novel scaffold-free approaches based on cellular self-assembly or three-dimensional (3D) bioprinting have been recently pursued. Bioprinting is a relatively new technology where living cells with or without biomaterials are printed layer-by-layer in order to create 3D living structures. In 3D bioprinting, cell aggregates and hydrogels are termed as bioink used as building blocks that are placed by the bioprinter into precise architecture according to developed computer models. In this chapter, we focus on the scaffold-free, self-assembly based bioprinting approaches and some of the novel developments in this field. This chapter will also discuss the importance as well as the challenges for 3D bioprinting using stem cells. We aim to highlight the importance of the continuous cell printing in order to fabricate 3D biological structures with predefined shapes as being the building blocks of large and complex tissues

Lactobacilli prevent overproduction of pathogenic microorganisms and contribute protecting vaginal microbiota. Many probiotic microorganisms are categorized as Lactic Acid Bacteria. In this study, it was aimed identifying probiotic characteristics of Lactobacillus crispatus isolated from the vagina of a healthy woman. For this purpose, lactic acid, hydrogen peroxide and proteolytic activity quantities and auto-aggregation, co-aggregation and hydrophobicity abilities of Lactobacillus crispatus, which has been isolated and identified by 16s rRNA sequence analysis, were determined. Additionally, bile salt and acid resistance, along with antibiotic susceptibility of Lactobacillus crispatus were analyzed by the end of 3 hours. Lactic acid, hydrogen peroxide and proteolytic activity quantities of Lactobacillus crispatus were measured 2.275%, 0.334±0.075 µg/mL and 2.131±0,000 mg/mL respectively. The findings include existence of co-aggregation and auto-aggregation ability, but not hydrophobicity. By the end of 3 hours, the viability was preserved in 0.1% and 0.3% bile salt medium and, at pH 3. L. crispatus exhibited resistance to methicillin, metronidazole, oxacillin, and sulfamethoxazole + trimethoprim, but the bacteria exhibited susceptibility to tested the other antibiotics. This study will make an important contribution to the literature about probiotic characteristics of L. crispatus and our strain isolated from the vagina might be considered as a candidate probiotic

Examining to see elite sight-disabled athletes according to the dimensions of the scale of motivation in sport

Made the purpose of this study is to examine to see disabled athletes according to the dimensions of the scale of motivation in sport. The study group is comprised of 168 visually impaired athletes in total, including 51 females and 117 males, identified by the targeted sampling method, between the ages of 15-25, who do sports at elite level. The Sport Motivation Scale (SMS) was developed by Pelletier (1995) basing on the Theory of Self Determination by Deci and Ryan (1985). The purpose of SMS is to determine the level of "internal motivation, external motivation and nonmotivation” of the person in the sports environment and to identify the source of motivation of the person (Kazak, 2004). Validity and reliability of the scale for Turkish athletes was studied by Kazak (2004).  In conclusion, this study has demonstrated that to know and succeed and to experience stimuli and identification subdimensions are effective in sports attendance of visually impaired athletes engaged in sports at elite level. Moreover, it has been demonstrated that age, education level and sports branch variables have an impact on tendency for sports. It can be concluded that compared to older athletes, younger athletes have low tendency for sports because of anxiety and embarrassment and are not conscious about why they do sports. It has been concluded that athletes of weight lifting and judo, which have contribution to physical development at the top level, believe the nature of their sports branch contributes more to their physical development and their strength is acknowledged and appreciated by other people.// Annotate Highligh

A Matrix Decomposition Method for Optimal Normal Basis Multiplication

We introduce a matrix decomposition method and prove that multiplication in GF(2^k) with a Type 1 optimal normal basis for can be performed using k^2-1 XOR gates irrespective of the choice of the irreducible polynomial generating the field. The previous results achieved this bound only with special irreducible polynomials. Furthermore, the decomposition method performs the multiplication operation using 1.5k(k-1) XOR gates for Type 2a and 2b optimal normal bases, which matches previous bounds

Prevalence of Metabolic Syndrome in Patients with Psoriasis

Background. Psoriasis is a chronic inflammatory skin disorder in which proinflammatory cytokines including IL-6 and TNF-α increase both locally and systematically. It is thought that chronic inflammation results in metabolic diseases and proinflammatory cytokines give rise to the development of atherogenesis, peripheral insulin resistance, hypertension, and type 2 diabetes. Our aim was to investigate the prevalence of metabolic syndrome in patients with psoriasis vulgaris. Methods. Study consisted of 115 plaque-type psoriasis patients and 140 healthy individuals. Data including body weight, height, waist circumference, body-mass index, and arterial blood pressure were collected. Fasting blood glucose, triglyceride, and HDL levels were determined. International Diabetes Federation Criteria for Metabolic Syndrome and Insulin Resistance were used for evaluating patients with metabolic syndrome and diabetes. Results. Compared to the control group, metabolic syndrome, diabetes mellitus, and hypertension were found to be higher in psoriasis patients. Metabolic syndrome was increased by 3-folds in psoriasis patients and was more prevalent in women than in men. It was determined that the prevalence of metabolic syndrome was higher in psoriasis patients after the age of 40. Metabolic syndrome was not related to smoking, severity of psoriasis, and duration of disease. Conclusions. Our findings suggest that psoriasis preconditions occurrence of a group of diseases such as diabetes mellitus, hypertension, and metabolic syndrome. For this reason, patients with psoriasis should be treated early and they should be followed with respect to metabolic diseases

3D hybrid bioprinting of macrovascular structures

Thousands of people die each year due the cardiovascular health problems. The most common treatments for cardiovascular health diseases are autografts and blood vessel transplantations which has limitations due to lack of donors and the patient's conditions. Although there are several scaffold based studies about vascular tissue engineering, scaffold-based vascular grafts have some side effects including chronic inflammation, thrombosis and rejection after in-vivo implantation. Additionally, there are some problems with cell to cell interaction, the assembly and alignment of ECM components and the host response to scaffolds. Therefore, vascular tissue engineering studies tend towards scaffold-free techniques. In this paper, novel computer aided algorithms and methods are developed for 3D printing of scaffold-free macrovascular structures. An example aorta model is generated using imaging and segmentation software. The developed algorithms are implemented using Rhinoscript. In order to support printed cell aggregates, support structures with 'Cake' and 'Zigzag' patterns are developed and 3D printed

Clinical value of pre-operative polyvinyl alcohol embolization in juvenile nasopharyngeal angiofibroma

Jüvenil nazofarengeal anjiofibromun tedavisinde pre-operatif embolizasyonun yeri tartışmalıdır. Embolizasyonun klinik etkinliğini değerlendirmek amacıyla, kliniğimizde 1994-2000 yılları arasında histopatolojik tanısı Jüvenil nazofarengeal anjiofibrom gelen, embolizasyon uygulanan ve uygulanmayan on hasta retrospektif olarak analiz edilmiştir. Bu vakaların beşine polivinil alkol ile selektif embolizasyon uygulanmıştır. Sadece cerrahi tedavi uygulanan olgulardaki intra-operatif kanama miktarı ortalama 2530 cc, verilen transfüzyon ünitesi ortalama 4.4 unit olarak bulunmuştur. Cerrahi öncesi pre-operatif embolizasyon uygulanan olgularda ise intra-operatif kanama miktarı ortalama 1590 cc, verilen transfüzyon ünitesi ise ortalama 2 unittir. Sonuçlar, pre-operatif polivinil alkol ile embolizasyonun intra-operatif kanama miktarını, transfüzyon ihtiyacını ve operasyon süresini azaltmada güvenilir ve etkili bir yöntem olduğunu göstermiştir.Role of the pre-operative embolization in the treatment of Juvenile nasopharyngeal angiofibroma, is controversial. For the purpose of evaluating clinical effectiveness of embolization, ten patients who came to our clinic with histopathological diagnosis of Juvenile nasopharyngeal angiofibroma and who are and not administered embolization between 1994 and 2000, have been retrospectively analyzed. in five of the cases, selective embolization method has been administered with polyvinyl alcohol (PVA). in cases where only surgical treatment is administered, it is found that average intraoperative bleeding amount is 2530 cc and transfusion unit administered is 4.4 units, in the cases where preoperative embolization is administered, intraoperative bleeding amount is 1590 cc and number of transfusion units is 2. Results indicated that embolization with preoperative polyvinyl alcohol is a reliable and effective method in decreasing the amount of intraoperative bleeding, transfusion need and duration of the surgical operation

3D bioprinting of biomimetic aortic vascular constructs with self-supporting cells

Cardiovascular diseases are the leading cause of deaths throughout the world. Vascular diseases are mostly treated with autografts and blood vessel transplantations. However, traditional grafting methods have several problems including lack of suitable harvest sites, additional surgical costs for harvesting procedure, pain, infection, lack of donors and even no substitutes at all. Recently, tissue engineering and regenerative medicine approaches are used to regenerate damaged or diseased tissues. Most of the tissue engineering investigations have been based on the cell seeding into scaffolds by providing a suitable environment for cell attachment, proliferation and differentiation. Because of the challenges such as difficulties in seeding cells spatially, rejection and inflammation of biomaterials used, the recent tissue engineering studies focus on scaffold-free techniques. In this paper, the development of novel computer aided algorithms and methods are developed for 3D bioprinting of scaffold-free biomimetic macrovascular structures. Computer model mimicking a real human aorta is generated using imaging techniques and the proposed computational algorithms. An optimized three-dimensional bioprinting path planning are developed with the proposed self-supported model. Mouse embryonic fibroblast (MEF) cell aggregates and support structures (hydrogels) are 3D bioprinted layer-by-layer according to the proposed self-supported method to form an aortic tissue construct
