Seniausiosios išlikusios originalios 1705–1726 m. Stakliškių bažnyčios krikšto metrikų knygos fragmento (1705–1710) publikacija
Transcriptions of the Stakliškiai church metrics can be found dated from 1699 to 1798 while originals are available from 1705 to modern times. The article presents a church metrics fragment (1705–1710) which is part of the oldest remaining original Stakliškiai church baptism metrics dated 1705–1726. This period was chosen because in 1710 the plague made fundamental changes in the demographic situation of the town and other neighboring settlements. The main aim of the publication is to present the text not only semantically but also graphically. The entries are ordered this way: first column – the day, second column – name of the town, third column – the year, month and the whole text of the entry: name of the baptized baby, names of the parents, names of the godparents, area information and other additional notes e.g. information on the nobility of those present at the ceremony. The presented fragment is not only important to researchers of the specific town and area but also could serve as an example for preparing and researching other metrics books. Metrics books are important not only to genealogy researches but also to researchers of local history and specialists of demographics, linguistics or religious sciences.Straipsnyje pristatomas seniausios išlikusios 1705–1726 m.

The Dynamics of Inflammatory Markers in Patients with Suspected Acute Appendicitis
Background: Laboratory tests of inflammatory mediators are routinely used in the diagnosis of acute appendicitis (AA). The aim of this study was to evaluate the differences of dynamics of inflammatory markers of the blood in patients with suspected acute appendicitis between complicated AA (CAA), non-complicated AA (NAA), and when AA was excluded (No-AA). Methods: This was a retrospective analysis of prospectively collected data of patients presented to the Emergency Department (ER) of a tertiary hospital center during a three-year period. All patients suspected of acute appendicitis were prospectively registered from 1 January 2016 to 31 December 2018. The dynamics of inflammatory markers of the blood between different types of AA (No-AA, NAA or CAA) during different periods of time are presented. Results: A total of 453 patients were included in the study, with 297 patients in the No-AA group, 99 in the NAA group, and 57 in the CAA group. White blood cell (WBC) count in the No-AA decreased with time, with a statistically significant difference between the <8 h and 25–72 h group. The neutrophils (NEU) percentage decreased in the No-AA group and was statistically significantly different between the <8 h and 25–72 h and <8 h and >72 h groups. C-reactive protein (CRP) increased significantly in the No-AA group throughout all time intervals, and from the first 24 h to the 25–72 h in the NAA and CAA groups. There was a statistically significant difference between the WBC count between No-AA, NAA, and No-AA and CAA groups during the first 24 and 24–48 h. There was a statistically significant difference between NEU percentage and LYMP percentage and in the NEU/LYMP ratio between No-AA and CAA groups through all time periods. CRP was significantly higher in the first 24 h in the CAA than in the No-AA group, and in the 24–48 h in the CAA group than in the No-AA and NAA groups. The linear logistic regression model, involving inflammatory mediators and clinical characteristics, showed mediocre diagnostic accuracy for diagnosing AA with an AUC of 0.737 (0.671–0.802). Conclusions: Increasing concentrations of inflammatory markers are more characteristic in CAA patients than in No-AA during the first 48 h after onset of the disease. A combination of laboratory tests with clinical signs and symptoms has a mediocre diagnostic accuracy in suspecting AA
Optimizing thermal profiles and stability for growth of bulk crystals in the B2O3-BaO-Na2O system /
The growth of bulk single crystals is crucial for numerous practical applications across various industries. Despite the strong demand driven by the well-developed laser technology industry and scientific research in laser applications, there appears to be a notable gap in research conducted within Lithuania on this crucial topic. To fill this void and make a meaningful contribution to the field, we have undertaken a focused project centered on bulk single crystal growth. We have designed and constructed a two-zone resistive heating vertical tube furnace with a 70 mm internal diameter. This furnace incorporates a seed pulling and rotating mechanism, enabling us to conduct top-seeded solution growth (TSSG) experiments. Our current research targets the B2O3-BaO-Na2O system, suitable for the growth of barium metaborate crystals. Literature suggests that achieving high axial and radial temperature gradients in the solution is crucial for successful crystal growth.1 Therefore, we optimized the furnace design to achieve these gradients. By adjusting heater powers in two zones and modifying the furnace cover design, we attained temperature differences of over 20 degrees between the top and bottom of the solution at the center, and over 10 degrees between the center and periphery of the solution at the surface. Our study investigates temperature stability, vertical temperature distribution (at the center and sides of the crucible), and circular temperature distribution near the crucible wall. We found that the furnace cover design significantly influences stability and temperature distribution. Large opening holes in the cover resulted in unstable air convection, leading to substantial temperature deviations in the melt, while using smaller holes produced more stable conditions. We will present the results of these measurements, along with initial crystal growth trials, in a poster presentation during the conference
Towards a self-powered amperometric glucose biosensor based on a single-enzyme biofuel cell /
This paper describes the study of an amperometric glucose biosensor based on an enzymatic biofuel cell consisting of a bioanode and a biocathode modified with the same enzyme—glucose oxidase (GOx). A graphite rod electrode (GRE) was electrochemically modified with a layer of Prussian blue (PB) nanoparticles embedded in a poly(pyrrole-2-carboxylic acid) (PPCA) shell, and an additional layer of PPCA and was used as the cathode. A GRE modified with a nanocomposite composed of poly(1,10-phenanthroline-5,6-dione) (PPD) and gold nanoparticles (AuNPs) entrapped in a PPCA shell was used as an anode. Both electrodes were modified with GOx by covalently bonding the enzyme to the carboxyl groups of PPCA. The developed biosensor exhibited a wide linear range of 0.15–124.00 mM with an R2 of 0.9998 and a sensitivity of 0.16 μA/mM. The limit of detection (LOD) and quantification (LOQ) were found to be 0.07 and 0.23 mM, respectively. The biosensor demonstrated exceptional selectivity to glucose and operational stability throughout 35 days, as well as good reproducibility, repeatability, and anti-interference ability towards common interfering substances. The studies on human serum demonstrate the ability of the newly designed biosensor to determine glucose in complex real samples at clinically relevant concentrations

Development of a new biocathode for a single enzyme biofuel cell fuelled by glucose
In this study, we reported the development of Prussian blue (PB), poly(pyrrole-2-carboxylic acid) (PPCA), and glucose oxidase (GOx) biocomposite modified graphite rod (GR) electrode as a potential biocathode for single enzyme biofuel cell fuelled by glucose. In order to design the biocathode, the GR electrode was coated with a composite of PB particles embedded in the PPCA shell and an additional layer of PPCA by cyclic voltammetry. Meanwhile, GOx molecules were covalently attached to the carboxyl groups of PPCA by an amide bond. The optimal conditions for the biocathode preparation were elaborated experimentally. After optimization, the developed biocathode showed excellent electrocatalytic activity toward the reduction of H2O2 formed during GOx catalyzed glucose oxidation at a low potential of 0.1 V vs Ag/AgCl, as well as good electrochemical performance. An electrocatalytic current density of 31.68 ± 2.70 μA/cm2 and open-circuit potential (OCP) of 293.34 ± 15.70 mV in O2-saturated 10 mM glucose solution at pH 6.0 were recorded. A maximal OCP of 430.15 ± 15.10 mV was recorded at 98.86 mM of glucose. In addition, the biocathode showed good operational stability, maintaining 95.53 ± 0.15% of the initial response after 14 days. These results suggest that this simply designed biocathode can be applied to the construction of a glucose-powered single enzyme biofuel cell
