The Influence of Terfenol-D Content on the Structure and Properties of Multiferroic Composites Obtained Based on PZT-Type Material and Terfenol-D.

In this work, three composite materials based on Terfenol-D and PZT-type material were obtained with a classic sintering method using a combination of 0-3 phases, where the ferroelectric phase was doped PZT material (P) and the magnetic phase was Terfenol-D (T). The percentage of P and T components in the composites was variable, i.e.

Unveiling the enigma: a case-based review of scleromyxedema.

Scleromyxedema is a rare chronic fibromucinous disorder characterized by a generalized papular and sclerodermoid eruption. Despite its clinical significance, no definitive therapeutic guidelines exist for scleromyxedema, making management challenging. Herein, we present a case of a 76-year-old female patient referred for evaluation of systemic sclerosis, presenting with distinctive cutaneous manifestations and neurological symptoms.

Log BB Prediction Models Using TLC and HPLC Retention Values as Protein Affinity Data.

Background: The penetration of drugs through the blood-brain barrier is one of the key pharmacokinetic aspects of centrally acting active substances and other drugs in terms of the occurrence of side effects on the central nervous system. In our research, several regression models were constructed in order to observe the connections between the active pharmaceutical ingredients' properties and their bioavailability in the CNS, presented in the form of the log BB parameter, which refers to the drug concentration on both sides of the blood-brain barrier.

Methods: Predictive models were created using the physicochemical properties of drugs, and multiple linear regression and a data mining method, i.

Automatic assessment of nailfold capillaroscopy software: a pilot study.

Introduction: Capillaroscopy is a simple method of nailfold capillary imaging, used to diagnose diseases from the systemic sclerosis spectrum. However, the assessment of the capillary image is time-consuming and subjective. This makes it difficult to use for a detailed comparison of studies assessed by various physicians.

Comparison of 15% 5-aminolevulinic acid and 10% 5-aminolevulinic acid photodynamic therapy for the treatment of acne vulgaris: a split-face randomized pilot study.

Introduction: Acne vulgaris is a highly prevalent skin disorder, driving the ongoing search for innovative treatment modalities. While numerous studies have demonstrated the effectiveness of photodynamic therapy (PDT) in managing acne vulgaris, there remains a lack of clear guidlines regarding optimal treatment parameters.

Aim: To assess the efficacy and safety of 10% concentration 5-aminolevulinic acid-(ALA) in comparison to 15% ALA PDT for treating facial acne vulgaris.

Single and consecutive 10-day remote ischemic preconditioning modify physical performance, post-exercise exerkine levels, and inflammation.

Purpose: Remote ischemic preconditioning (RIPC) is a method of protection against induced ischemia reperfusion injury, and an increasing number of studies showed some of its inconclusive ergogenic effects in sports. RIPC involves short cycles of cuff inflation followed by its deflation which may affect many body systems. While most of the studies focus on single RIPC effects, there is insufficient data regarding training-like repeated RIPC interventions.

Hybrid Supports for Oligonucleotide Synthesis: Controlled Pore Glass Derivatives with Branched Amine-Ended Polyether or Polyimine.

Controlled pore glass (CPG), differing in pore size and subsequent specific surface, was chemically modified by: (1) increasing surface susceptibility for amine functionalization via reaction with oxirane-type (active) and alkyl/aryl-type (inactive towards amine compounds) silane pro-adhesive compounds, and (2) immobilization of trimethylolpropane tris[poly(propylene glycol), amine terminated] ether, comb-like 8-arm octa[poly(ethylene glycol) amine] with each branch amine terminated, and a poly(propylene imine) amine-terminated second-generation dendrimer. The increase in surface density of amine functions - monitored by UV-Vis technique adopted for quantitative measurements of Ruhemann's purple intensity - improved final loading capacity, characterized by dimethoxytrityl cation absorption. Obtained materials proved their applicability in automatic oligonucleotide (ON) synthesis, especially when silanized 2000 Å CPG modified with 8-arm octa[poly(ethylene glycol) amine], with deduced empirical formula CPG - silane - (NH)PEG-(NH), was used for long-chain (150 nucleotides) ONs synthesis.

Properties of Sn-Doped PBZT Ferroelectric Ceramics Sintered by Hot-Pressing Method.

This work investigated the structure, microstructure, and ferroelectric and dielectric behavior of (PbBa)(ZrTi)SnO (PBZT_Sn) solid solution with variable tin content in the range = 0.00-0.08.

Response of Circulating Free Cellular DNA to Repeated Exercise in Men with Type 1 Diabetes Mellitus.

Intense exercise leads to neutrophil extracellular traps (NETs) formation, which triggers cell disintegration. NET, as well as other processes of apoptosis, necrosis, and spontaneous secretion, result in increased levels of cell-free DNA (cf-DNA) in the circulation. An increment of cf-DNA is also observed in autoimmune diseases, such as type 1 diabetes mellitus (T1DM).

tuberculosis in a captive lion in Ukraine - Case Report.

. Because of the armed conflict in Ukraine, companion, farm and captive wild animals have been moved in a simplified procedure across the Polish-Ukrainian border. For that reason, in 2022, Poznań Zoo provided support for almost 200 wild animals before movement to facilities in other countries.

Heart involvement in patients with systemic sclerosis-what have we learned about it in the last 5 years.

This review provides a detailed examination of original research and previously published reviews regarding cardiovascular involvement in systemic sclerosis (SSc). Our study aims to evaluate the current understanding of SSc-associated heart involvement (SHI), focusing on its most prevalent forms, diagnostic methods and treatment options.

Effect of Single High-Dose Vitamin D Supplementation on Post-Ultra Mountain Running Heart Damage and Iron Metabolism Changes: A Double-Blind Randomized Controlled Trial.

Exercise-induced inflammation can influence iron metabolism. Conversely, the effects of vitamin D, which possesses anti-inflammatory properties, on ultramarathon-induced heart damage and changes in iron metabolism have not been investigated. Thirty-five healthy long-distance semi-amateur runners were divided into two groups: one group received 150,000 IU of vitamin D 24 h prior to a race ( = 16), while the other group received a placebo ( = 19).

Anti-Th/To Antibodies in Scleroderma: Good Prognosis or Serious Concern?

Systemic sclerosis (SSc) represents a rare and intricate autoimmune connective tissue disease, the pathophysiology of which has not been fully understood. Its key features include progressive fibrosis of the skin and internal organs, vasculopathy and aberrant immune activation. While various anti-nuclear antibodies can serve as biomarkers for the classification and prognosis of SSc, their direct role in organ dysfunction remains unclear.
