Understanding the Role of Longitudinal Arterial Wall Motion in Blood Circulation from the Perspective of a Piano String*

Background: From the evidence of failed injection-based growth factor therapies, it has been proposed that a naturally triggered uninterrupted blood circulation of the growth factors would be superior. Objective: We seek to stimulate discussions and more research about the possibility of using the already available growth factors found in the prostate gland and endometrium by starting a novel educable physiology, known as biological transformations controlled by the mind. Methods: We summarized the stretch-gated ion channel mechanism of the cell membrane, and offer several practical methods that can be applied by anyone, in order to stimulate and enhance the blood circulation of the growth factors from the seminal fluid to sites throughout the body. This details the practical application of our earlier published studies about biological transformations. Results: A previously reported single-patient case study has been extended, adding more from his personal experiences continually improving this novel physiological training and extending the ideas from our earlier findings in detail. Conclusion: The biological transformation findings demonstrate the need additional research to establish the benefits of these natural therapies to repair and rejuvenate tissues affected by various chronic diseases or aging processes.

The present paper examines the relation between different developed microstructures and the microwave electromagnetic properties in Ni-Zn-Co ferrite. To this end, the Ni0.25Zn0.25Co0.5Fe2O4composition has been prepared with the conventional ceramic process with varied prefiringTP(750°C, 1000°C) and sinteringTStop temperatures (1200°C, 1250°C). When lower temperatures are applied in these production stages, incomplete microstructures with low density, higher porosity, or finer grains are achieved. On account of these features, the contributions of domain wall motion and spin rotation to the complex permeabilityμ⁎(f)move to higher frequencies, whereas microwave dielectric permittivityε⁎(f)is decreased. In particular in conjunction with the high Co content, the wall relaxation and spin resonance are interestingly forced to occur at 850 MHz and 8.05 GHz, respectively. Regarding the electromagnetic wave attenuation, the ferrite annealed at lower temperatures exhibits strong return loss peaks at higher frequencies, but without other performance improvement. We should notice that the variations in sintering temperatureTSyield the maximum changes in the recorded parameters, including the coercive field,μ⁎(f),andε⁎(f), indicating the inferior role of prefiringTPin Ni-Zn ferrite.

Pseudoexfoliative Glaucoma

Introduction: Primary open-angle glaucoma (POAG) is one of the most prevalent causes of irreversible blindness and is associated with endothelial dysfunction and arterial stiffness. Pseudoexfoliative glaucoma (PEG) is another type of glaucoma observed in pseudoexfoliation syndrome. It is characterized by the deposition of pseudoexfoliative material not only to the anterior segment of the eye, but also to the vessels, heart and other organs. Hypothesis: Endothelial function and arterial stiffness are impaired in patients with POAG and PEG supporting the significant role of vascular function impairment in the progression of the disease. Methods: Forty four POAG patients, 22 PEG and 38 healthy subjects (Cl) were included in this study. All subjects were free of cardiovascular or inflammatory diseases. Endothelial function was evaluated by flow-mediated dilatation (FMD). Carotid-femoral pulse wave velocity (PWV) was measured as an index of aortic stiffness and augmentation index (AIx) as a measure of arterial wave reflections Results: Between the three study groups CL, POAG, PEG there was no difference in age (67±10years vs. 70±9years vs. 66±12yeras, p=0.12) or prevalence of male sex (70% vs. 57% vs. 50%, p=0.21). Importantly, there was a linear impairment of FMD (7.35±2.77% vs. 6.58±3.18% vs. 4.88±3.29%, p=0.006), PWV (7.98±1.56m/sec vs. 9.20±1.84m/sec vs. 9.22±2.16m/sec, p=0.004) and AIx (21.29±8.77% vs. 25.14±5.71% vs. 28.20±8.75%, p=0.002) from CL to POAG and PEG. Interestingly post hoc test after Scheffe correction revealed also that PEG subjects had not only significantly impaired FMD, compared to control subjects, but also compared to POAG subjects (4.88±3.29% vs. 6.58±3.18%, p=0.02). Conclusions: Endothelial function and arterial stiffness are significantly impaired in patients with pseudoexfoliative glaucoma. These findings shed some light in the pathophysiology of pseudoexfoliative glaucoma and support the theory that pseudoexfoliative fibrils may also accumulate and damage the arterial wall.

Total Splenectomy

The spleen is a secondary lymphoid organ that belongs to the reticular-endothelial system, directly connected to blood circulation. The spleen is greatly involved in the immune response, especially against capsulated bacteria. Splenectomy plays a fundamental role in the treatment of numerous pediatric hematologic disorders. Taking into account all the possible complications (especially infections) linked to this procedure, alternatives to total splenectomy have been sought. Partial splenectomy has been proposed as a treatment that allows the reduction of infectious risk. This approach has proven safe and feasible in most patients, but multicentric and prospective studies are necessary to more accurately define the indications for performing partial splenectomy. However, vaccinations and antibiotic prophylaxis remain fundamental for preventing serious infections, even in the case of partial splenectomy. We review anatomical and functional properties of the spleen, with a focus on medical or surgical indications to splenectomy, aiming to give practical educational information to patients and their families after splenectomy. Furthermore, we discuss the feasibility of partial splenectomy in children with hematologic diseases who require splenectomy.

ABSTRACT Introduction: Physical exercise can enhance the body's ability to adapt to the external environment and improve the contractility of the heart. At the same time, it can help improve blood circulation and increase lung capacity. Objective: This article explores the critical role of sports in the prevention of cardiovascular diseases. Methods: This article conducts tests on related physiological indicators such as hemodynamic rheology for students who regularly participate in physical exercise and those who do not participate in physical exercise. Results: Students who exercise regularly and those who do not exercise mobilize faster cardiovascular function at the beginning of work. This shows good adaptability to sports. Conclusion: The use of fitness exercise prescription by students who exercise comprehensively has the most pronounced effect on improving vascular function. Level of evidence II; Therapeutic studies - investigation of treatment results.
