The Correlation of Serum Calpain 1 Activity and Concentrations of Interleukin 33 in COVID-19 Acute Respiratory Distress Syndrome.

Acute respiratory distress syndrome (ARDS) is one of the most severe complications of the COVID-19 disease. The role of IL-33 and calpain 1 was previously described in lung infections and lung tissue damage. Our study examined the association between serum calpain 1 activity and IL-33 concentration in patients with COVID-19 ARDS.

Lateral orbital wall reconstruction after basal cell carcinoma penetration-Case report.

Advanced periorbital basal cell carcinomas may necessitate orbital exenteration and consequent vision loss, which significantly reduces patients' life quality. Orbital reconstruction is a demanding surgical procedure due to the complex orbital anatomy and vital structures located in the orbit. In this report, we presented an 83-year-old patient with advanced basal cell carcinoma that had expanded into the orbit.

Sol-Gel Synthesis of Ceria-Zirconia-Based High-Entropy Oxides as High-Promotion Catalysts for the Synthesis of 1,2-Diketones from Aldehyde.

Efficient Lewis-acid-catalyzed direct conversion of aldehydes to 1,2-diketones in the liquid phase was enabled by using newly designed and developed ceria-zirconia-based high-entropy oxides (HEOs) as the actual catalysts. The synergistic effect of various cations incorporated in the same oxide structure (framework) was partially responsible for the efficiency of multicationic materials compared to the corresponding single-cation oxide forms. Furthermore, a clear, linear relationship between the Lewis acidity and the catalytic activity of the HEOs was observed.

SURGICAL ASPECT OF BLEPHAROSPASM TREATMENT: A CASE REPORT.

Blepharospasm is an idiopathic condition characterized by involuntary eyelid closure mainly caused by bilateral tonic-clonic contractions of the orbicularis oculi muscle. It results in patient inability to open their eyes, thus significantly impairing their ability to perform activities of daily living. First-line treatment for blepharospasm are primarily botulinum toxin type A injections.

IN SEARCH FOR REAL-TIME NONINVASIVE ASSESSMENT OF MUSCLE FATIGUE DURING EXERTION: CAN DISPERSION OF HIGH-RESOLUTION MUSCLE ELECTRIC ACTIVITY DATA PROVIDE NEW INSIGHTS?

- Paralumbar muscle performance and fatigue were evaluated by measuring electromagnetic activity during entire body vibration (EBV) in 44 healthy subjects. Physical fitness of subjects was estimated on a 5-degree scale. Electric activity was recorded in 200 seconds with 1 kHz sampling on the Biopac Student Lab during EBV.

Cochlear potential difference between endolymph fluid and the hair cell's interior: a retold interpretation based on the Goldman equation.

Reported cochlear potential values of near 150 mV are often attributed to endolymph itself, although membrane potentials result from ion fluxes across the adjacent semipermeable membranes due to concentration gradients. Since any two fluids separated by a semipermeable membrane develop potential due to differences in solute concentrations, a proposed interpretation here is that positive potential emanates from the Reissner membrane due to small influx of sodium from perilymph to endolymph. Basolateral hair cell membranes leak potassium into the interstitial fluid and this negative potential inside hair cells further augments the electric gradient of cochlear potential.

Hidden information in three-axial ECG data of normal subjects: Fractal dimensions of corresponding points from successive QRS loops as a potential sport and age dependent marker.

This study is aimed to estimate spatial variability of normal QRS loops trajectories in successive cardiac cycles analyzed in XYZ phase space among 27 young and 27 older subjects, both male and female. Among young subjects, 10 individuals were professional football players, while the remaining 17 were students without regular physical activities. Modified three-axial leads (Frank's lead system) were used continually to record high-resolution ECG (1 kHz sampling rate) at rest during 200 seconds by Biopac Student Lab System.

Intraoral adenoid cystic carcinoma: is the presence of perineural invasion associated with the size of the primary tumour, local extension, surgical margins, distant metastases, and outcome?

Adenoid cystic carcinoma is the most common malignancy of the minor salivary glands, and its biological behaviour is characterised by slow and indolent growth; rare involvement of regional lymph nodes; a high propensity for perineural invasion; multiple or delayed recurrences, or both; and a high incidence of distant metastases. Our aim was to find out the relation between the presence of perineural invasion and these factors. Between 1 January 1984 and 1 May 2008, 26 cases of adenoid cystic carcinoma of the intraoral salivary glands, which had initially been treated surgically, were reviewed retrospectively.

Evaluation of influences of the Viennese Anatomical School on the work of the Croatian Anatomist Jelena Krmpotic-Nemanic.

Objective: This paper tries to evaluate the connections between the Viennese Anatomical School and the Croatian Anatomist Jelena Krmpotic-Nemanic.

Materials And Methods: 17 papers written by Professor Jelena Krmpotic-Nemanic in the last decade of her life were chosen for analyses. According to their themes they could be divided into three groups: ones which evaluate the anatomical terminology, ones which research the development of anatomical structures, and ones which describe the anatomical variations.

The importance of thorough preoperative diagnostics of maxillary ameloblastoma: report of three cases.

Ameloblastoma, especially maxillary, is a rare benign neoplasm of odontogenic origin. Diagnosis of significant number of lesions is usually established postoperatively, because ameloblastoma, especially the unicystic form, mimics wide range of more frequent jaw lesions. From January 1993 to December 2005, three cases of the maxillary ameloblastoma were surgically treated at our Department.

Clinical characteristics of patients with spondyloarthritides and HLA-B27 positive antigen.

The aim of this study was to present our experiences in diagnosing spondyloarthritides (SpA), and to list the most common clinical features of HLA-B27 positive patients. The study included 65 HLA-B27 positive patients with confirmed diagnosis of ankylosing spondylitis (AS) and psoriatic arthritis (PsA) who were analyzed between 2009 and 2010 in Clinic of Internal Medicine in Osijek. The diagnosis of seronegative spondyloarthritides was based on the ASAS (Assessment in AS Working Group) classification criteria for axial and then supplemented with ASAS criteria for peripheral SpA and was confirmed by radiological techniques.

Real mineral density of the sternum.

Mineral density of the sternum is insufficiently known. The aim of this research was to investigate mineralisation of the sternum and collect normative data on mineral density of the standard male and female sternum in elderly people (average age of female samples was 64 and male's was 62 years). The research was conducted on 93 cadaveric sternums, 56 male and 37 female samples.

[Prevalence of acute cerebrovascular disease in Bizovac, Osijek-Baranya county: a door-to-door survey in eastern Croatia].

Background And Purpose: A door-to-door survey was carried out in Bizovac area, Osijek-Baranya County in east Croatia. A cluster sample of 1899 inhabitants were screened to determine the prevalence of acute cerebrovascular disease (CVD): transient ischemic attacks (TIA) and stroke in this population.
