Chemically Pretreated Densification of Juniper Wood for Potential Use in Osteosynthesis Bone Implants.

The aim of the study was to perform treatment of juniper wood to obtain wood material with a density and mechanical properties comparable to bone, thus producing a potential material for use in osteosynthesis bone implants. In the first step, partial delignification of wood sample was obtained by Kraft cooking. The second step was extraction with ethanol, ethanol-water mixture, saline, and water to prevent the release of soluble compounds and increase biocompatibility.

Craniofacial Measurements and Indices Trends in Latvian Children Aged 1-15.

Unlabelled: Craniofacial development is a critical aspect of pediatric growth, influencing fields such as physical anthropology, pediatrics, forensic sciences, and clinical practice.

Objectives: This study aimed to assess the trends in craniofacial measurements and indices in Latvian children aged 1-15.

Methods: The anthropometrical measurements (head circumference, length, width, facial length, and width) were conducted on 375 children according to the guidelines by R.

Longitudinal Analysis of Latvian Child Growth: Anthropometric Parameters Dynamics from Birth to Adolescence.

This study provides a comprehensive analysis of the physical development patterns from birth to adolescence, utilizing a longitudinal dataset of 70 children monitored from birth until 17 years of age. The research focuses on the variability of growth trajectories, emphasizing the role of genetic and environmental factors in influencing these patterns. Key findings indicate that most children undergo one or two periods of accelerated growth, with significant variability in the timing and magnitude of these growth spurts.

Rapidpulse cyclic aspiration system for acute ischemic stroke due to large vessel occlusions.

Background: The best strategy to achieve optimal reperfusion outcomes during mechanical thrombectomy remains to be defined. The RapidPulse Cyclic Aspiration System is a novel technology, delivering high-frequency pulsed vacuum forces to increase the efficiency of aspiration thrombectomy.

Methods: Prospective, multicenter, open-label, core lab-adjudicated, two-arm study comparing safety and efficacy of a feasibility version of the RapidPulse system compared with contemporary controls.

Documentary Assessment of the Abilities of Kyrgyzstan's Research Ethics Committees During Public Health Emergency and Non-Emergency Situations.

Institutional Research Ethics Committees (RECs) play crucial roles in the impartial and competent review of scientific research, particularly during public health emergencies. In this report, we examined their ability and capacity to provide this basic service during public health emergencies and non-emergency situations. Our qualitative documentary analysis revealed that there are currently no legal regulations guiding the activities of Kyrgyz RECs during public health emergencies.

Tenecteplase or Alteplase Better in Patients with Acute Ischemic Stroke Due to Large Vessel Occlusion: A Single Center Observational Study.

: The study aimed to investigate the efficacy of intravenous thrombolysis with Tenecteplase before thrombectomy for acute ischemic stroke (AIS) patients compared with previous results using Alteplase. Previous trials for Tenecteplase have indicated an increased incidence of vascular reperfusion. In April 2021, we started to primarily give Tenecteplase to patients eligible to undergo thrombectomy.

Improving the Recovery of Patients with Subacromial Pain Syndrome with the DAid Smart Textile Shirt.

Wearable technologies provide many possibilities for applications in medicine, and especially in physiotherapy, where tracking and evaluation of body motion are of utmost importance. Despite the existence of multiple smart garments produced for applications in physiotherapy, there is limited information available on the actual impact of these technologies on the clinical outcomes. The objective of this paper is to evaluate the impact of the Double Aid (DAid) smart shirt, a purely textile-based system, on the training process of patients with subacromial pain syndrome.

Is Anticoagulation Necessary for Severely Disabled Cardioembolic Stroke Survivors?

Oral anticoagulants are the hallmark of cardioembolic stroke prevention, but they are frequently underused, especially in elderly patients and patients with paroxysmal atrial fibrillation. In our paper, we analyzed the long-term outcome of severely disabled cardioembolic stroke survivors depending on the prescribed antithrombotic secondary prevention medication. In our study, we retrospectively collected data for ischemic stroke (IS) patients treated in P.

Age-related trends of lesser pelvic architecture in females and males: a computed tomography pelvimetry study.

The pelvis and the spine form a system balancing human skeleton. Within this system, the pelvis adapts to age-related changes in the spine. Previous studies were predominantly focused on changes of pelvic parameters in the sagittal plane.

An in vitro and in vivo study on the intensity of adhesion and colonization by Staphylococcus epidermidis and Pseudomonas aeruginosa on originally synthesized biomaterials with different chemical composition and modified surfaces and their effect on expression of TNF-α, β-defensin 2 and IL-10 in tissues.

Unlabelled: The aim of this study was to determine adhesion and colonization of bacteria on the surface of originally synthesized glass-ceramic biomaterials and their effect on inflammation reactions in tissues surrounding the implant.

Materials And Methods: Biomaterial discs were contaminated with bacterial suspensions of 10, 10(2), and 10(3) colony forming units (CFU)/mL (P. aeruginosa ATCC 27853 and S.

Growth factors, their receptors, neuropeptide-containing innervation, and matrix metalloproteinases in the proximal and distal ends of the esophagus in children with esophageal atresia.

Objective: The pathogenesis of esophageal atresia (EA) remains unknown despite a relatively high incidence of this anomaly in population affecting 1 newborn per 3000 live births. The aim of this study was to examine the relative occurrence of growth factors, their receptors, neuropeptide-containing innervation, and tissue-degradating enzymes--matrix metalloproteinases--in the proximal and distal parts of the esophagus with EA.

Materials And Methods: A histopathological study was conducted on 15 patients with EA.

Early morphofunctional response of contact tissue after intraosal implantation in rabbit jaw of pure synthetic hydroxyapatite (HAp) bioceramic materials and HAp saturated with lidocaine.

Purpose: The aim of this study was to evaluate early morphofunctional response of contact tissue to pure and saturated with lidocaine porous synthetic HAp ceramic implants inserted in holes of rabbit upper jaw.

Materials And Methods: Pure and saturated with lidocaine cylinders of porous HAp ceramics produced at Biomaterials R&D Laboratory of Riga Technical University were inserted into edentulous part of the upper jaw of 12 New Zealand male rabbits. After two weeks, blocks of soft tissue and bone were taken out.

Validity and reproducibility of cephalometric measurements obtained from digital photographs of analogue headfilms.

Unlabelled: The emerging market of digital cephalographs and computerized cephalometry is overwhelming the need to examine the advantages and drawbacks of manual cephalometry, meanwhile, small offices continue to benefit from the economic efficacy and ease of use of analogue cephalograms. The use of modern cephalometric software requires import of digital cephalograms or digital capture of analogue data: scanning and digital photography. The validity of digital photographs of analogue headfilms rather than original headfilms in clinical practice has not been well established.
