Medical imaging tests are widely used to diagnose a broad spectrum of lower-limb injuries. Among these modalities, ultrasound (US) imaging has gained significant traction as a valuable diagnostic instrument for assessing conditions primarily affecting muscles, tendons, ligaments, and other soft tissues. However, there are important dilemmas related to the indications and possibilities of US in lower-limb injuries.

Article Synopsis
  • The immunoglobulin fold (Ig fold) is a structural motif made of two layers of β-sheets found in various proteins with diverse biological roles, highlighting its importance in evolution and function.
  • Its modular architecture includes a conserved core of four β-strands and variable extensions, allowing for a range of evolutionary adaptations in both antibodies and other proteins across different life forms.
  • The overview discusses the structural and functional significance of the Ig fold in various biological processes, and explores its applications in biotechnology through natural adaptation and engineering.

Background: The prevalence of young patients with cardiac implantable electronic devices (CIED) is steadily increasing, accompanied by a rise in the occurrence of complications related to CIEDs. Consequently, transvenous lead extraction (TLE) has become a crucial treatment approach for such individuals.

Objective: The purpose of this study was to examine the characteristics and procedural outcomes of young patients who undergo TLE, with a specific focus on identifying independent risk factors associated with adverse events.

Aims: Heart failure with reduced ejection fraction (HFrEF) is associated with excessive sympathetic and impaired parasympathetic activity. The Barostim Neo™ device is used for electronical baroreflex activation therapy (BAT) to counteract autonomic nervous system dysbalance. Randomized trials have shown that BAT improves walking distance and reduces N-terminal prohormone of brain natriuretic peptide (NT-proBNP) levels at least in patients with only moderate elevation at baseline.

iCn3D was initially developed as a web-based 3D molecular viewer. It then evolved from visualization into a full-featured interactive structural analysis software. It became a collaborative research instrument through the sharing of permanent, shortened URLs that encapsulate not only annotated visual molecular scenes, but also all underlying data and analysis scripts in a FAIR manner.

The National Center for Biotechnology Information (NCBI) produces a variety of online information resources for biology, including the GenBank® nucleic acid sequence database and the PubMed® database of citations and abstracts published in life science journals. NCBI provides search and retrieval operations for most of these data from 35 distinct databases. The E-utilities serve as the programming interface for the most of these databases.

The VAST+ algorithm is an efficient, simple, and elegant solution to the problem of comparing the atomic structures of biological assemblies. Given two protein assemblies, it takes as input all the pairwise structural alignments of the component proteins. It then clusters the rotation matrices from the pairwise superpositions, with the clusters corresponding to subsets of the two assemblies that may be aligned and well superposed.

Motivation: Build a web-based 3D molecular structure viewer focusing on interactive structural analysis.

Results: iCn3D (I-see-in-3D) can simultaneously show 3D structure, 2D molecular contacts and 1D protein and nucleotide sequences through an integrated sequence/annotation browser. Pre-defined and arbitrary molecular features can be selected in any of the 1D/2D/3D windows as sets of residues and these selections are synchronized dynamically in all displays.

Introduction: The diagnostic process of bone tumors, including malignant ones, is based on conventional radiological methods, such as radiography and computed tomography, and with precise assessment of local advancement in magnetic resonance imaging. Ultrasonography is not included in the diagnostic algorithms as a tool suitable to detect this type of pathology. More and more frequent usage of musculoskeletal ultrasound in children as the first imaging method or, in some cases, as the only diagnostic method, makes it necessary to be familiar with sonographic presentation of bone tumors to suggest this diagnosis early enough and, after its verification, start treatment without a significant delay.

Background: Reducing post-sternotomy mediastinitis (PSM) requires incorporating multiple methods. However, the independent effects of these measures are not well studied.

Aim: To evaluate the independent effect of preoperative disinfection using isopropyl alcohol (IPA)-chlorhexidine gluconate (CHG) and the topical application of a retrosternal gentamicin collagen sponge at wound closure on reducing PSM.

The aim of the ultrasound (US) screening program was to detect neoplastic lesions in children, together with other pathologies of the developmental age in the area of the neck, abdomen, female pelvis, and scrotum in boys.US screening scans, including cervical, abdominal, pelvical, and scrotal US, were performed in the population of asymptomatic children aged from 9 months to 6 years. The children were scanned in Mobile Pediatric US Unit, consisting of 2 independent consulting rooms.

Background: Reducing surgical site infections (SSI) following median sternotomy remains a challenge for cardiac surgeons. Standard prophylaxis of SSI at our institution includes pre-operative skin disinfection with isopropyl alcohol (IPA). The addition of chlorhexidine gluconate (CHG) has the theoretical advantage of longer antimicrobial activity (>48h), compared with 2 h for IPA alone.

The computational detection of similarities between protein 3D structures has become an indispensable tool for the detection of homologous relationships, the classification of protein families and functional inference. Consequently, numerous algorithms have been developed that facilitate structure comparison, including rapid searches against a steadily growing collection of protein structures. To this end, NCBI's Molecular Modeling Database (MMDB), which is based on the Protein Data Bank (PDB), maintains a comprehensive and up-to-date archive of protein structure similarities computed with the Vector Alignment Search Tool (VAST).

The application of 3D imaging in pediatric rheumatology helps to make the assessment of inflammatory changes more objective and to estimate accurately their volume and the actual response to treatment in the course of follow-up examinations. Additional interesting opportunities are opened up by the vascularity analysis with the help of power Doppler and color Doppler in 3D imaging. Contrast-enhanced ultrasound examinations enable a more sensitive assessment of the vascularity of inflamed structures of the locomotor system, and a more accurate analysis of treatment's effect on changes in vascularity, and thereby the inflammation process activity, as compared to the classical options of power and color Doppler.

Protein homooligomers afford several important benefits for the cell; they mediate and regulate gene expression, activity of many enzymes, ion channels, receptors, and cell-cell adhesion processes. The evolutionary and physical mechanisms of oligomer formation are very diverse and are not well understood. Certain homooligomeric states may be conserved within protein subfamilies and between different subfamilies, therefore providing the specificity to particular substrates while minimizing interactions with unwanted partners.
