Highlights. The clinical case report describes the important role of MRI in the perinatal diagnosis of dural sinus thrombosis, timely verification of the diagnosis, differential diagnosis with other vascular and tumor formations of the brain.Abstract. Dural sinus thrombosis (DST) is a rare congenital anomaly. Ultrasound findings usually mimic intracranial tumors. As a result, the condition is often misdiagnosed and its frequency in general population is underestimated. According to literature data, the progression of DST is a favorable prognosis in case of absence of other concomitant pathologies of the fetal brain. We present a case of DST that was detected with ultrasound, and verified by numerous pre and postnatal MRI starting from 22 weeks of gestation till 4 years of life. A case with a favorable neurological outcome, postnatal ventriculosubgaleal shunting, and ventriculoperitoneal shunting was followed with MRI and CT before and after interventions. The aspects of differential diagnosis, factors determining prognosis are presented. The presented case demonstrates a significant role of fetal MRI in DST diagnosis, depiction of the internal structure of the expanded sinus, and exclusion of concomitant pathology of the brain. These MRI data are integral in determining the appropriate perinatal management, and can be used as predictors of the favorable neurological outcome despite of the severity and size of prenatally diagnosed DSТ.

Highlights. The article presents an analysis of the outcome of the project dedicated to cardiovascular disease prevention in the Regional Vascular Center, the analysis involved the assessment of changes in the characteristics of deceased patients. The study made it possible to identify changes in mortality rate, the impact of new diagnostic and treatment techniques and administrative decisions on the change in mortality, as well as aspects that prevent further reduction in mortality.Aim. To assess the results of the implementation of new methodological approaches to cardiovascular diseases prevention, myocardial infarction in particular, in the Regional Vascular Center.Methods. The study involved the analysis of the data (entered in real time) from the Emergency Cardiac Care Department of the Сardiology Research Institute, Tomsk National Research Medical Center of the Russian Academy of Sciences, and data from the Department`s database containing anamnestic and clinical characteristics of patients, and recording of deaths in the period from 2014 to 2019. Statistical data processing was performed using the StatSoft Statistica software (ver. 10.0).Results. From 2014 to 2019, percutaneous coronary intervention (PCI) in myocardial infarction (MI) increased from 48 to 67.4% (p˂0.05); the primary PCI in MI with ST segment elevation (STEMI) increased from 24% to 32% (p˂0.001), the overall frequency of PCI in STEMI (primary + rescue + delayed) increased from 59.6% to 73% (p˂0.05); PCI in MI without ST segment elevation (NSTEMI) increased from 23.9% to 43.9% (p˂0.001), the frequency of intra-aortic balloon counterpulsation increased from 0.6% to 1.5% (p˂0.05), the frequency of mechanical ventilation did not change (8,3 and 8,5%), moreover the widespread use of ticagrelor and prasugrel was noted. At the same time, hospital mortality of patients with MI decreased from 9.8 to 8.0% (p>0,05): in patients with STEMI it decreased from 10.7% to 7.7% (p = 0.047), in patients with NSTEMI there was no change in mortality, it remained equal to 8–9%. Implementation of coronary reperfusion strategies that do not involve streptokinase is associated with a decrease in hospital mortality of patients with STEMI.Conclusion. The widespread introduction of modern invasive and medicinal technologies has led to a decrease in mortality of patients with STEMI. Further increasing the number of available invasive procedures – PCI, intra-aortic balloon counterpulsation and mechanical ventilation for the purposes of reducing mortality of patients with MI seems questionable.

Highlights. Small cerebral aneurysms (<3 mm), which make up the majority of aneurysms, rupture more frequently, although medium (>3 mm) and giant (>15 mm) aneurysms and have a higher risk of rupture. This article proves for the first time that the rupture risk criteria developed for giant cerebral aneurysms do not work for small aneurysms. The development of small aneurysms in patients was analyzed and measured morphological features of aneurysms were compared with their calculated hydrodynamic characteristics.Aim. To study the dynamics of development of small cerebral aneurysms, to assess the applicability of existing methods for calculating the risk of rupture, to formulate new clarifying hypotheses for calculating the risk of rupture of small cerebral aneurysms.Methods. Patient data were provided by the Federal Center for Neurosurgery, Novosibirsk. CT angiography was performed using a Philips Ingenuite CT scanner (Philips Medical Systems, USA, 128 slices). Aneurysm size dynamics was assessed by measuring three main sizes with an accuracy of 0.1 mm using the IntelliSpace Portal Philips software environment. Numerical calculations were carried out using ANSYS CFX 2020R2.Results. Hemodynamic characteristics change according to the changes of the aneurysm dome. In the case when morphological characteristics of the aneurysm have not changed, a change in the geometry of the patient's circle of Willis (coW) is observed: the curvature of the arteries, the angles of bifurcations (the structure of coW remained unchanged). The PHASES score (absolute risks of rupture for aneurysms) was found to be unusable for the considered aneurysms.Conclusion. This work formulates and morphologically and hydrodynamically confirms for the first time in the volunteers that the change in risk estimates for such aneurysms is fundamentally affected, even insignificantly, by the change in the circle of Willis: a change in the curvature of individual segments of the cerebral arteries, as well as the angles of their bifurcations. The results obtained are aimed at modifying the existing risk criteria for rupture of cerebral aneurysms.

Published: April 2023

Highlights. The hypothesis of the evolution of LV twisting types is proposed, which is based on the gradual transformation of LV twisting types as a prerequisite for postnatal growth and development of heart chambers in healthy children and adolescents. In the future, the transition of one type of LV twist to another will enable us to diagnose the predominance of growth and maturation of the fibrous skeleton, apex, vortex cordis, trabecular apparatus, as well as creating projections of the individual development and growth of the heart in childhood and adolescence.Abstract. Modern data on the nature of the mechanics of the left ventricle (LV) in postnatal ontogenesis in healthy children and adolescents born full-term are fundamental, since they allow not only to determine ontogenetically conditioned variants of individual development of contractile-rotational mechanisms of LV in the process of growth and development, but also, if necessary, make it possible to identify subclinical dysfunction in the early stages, monitor the effectiveness of complex therapeutic and rehabilitation measures. The article analyzes newly established fact of the absence of static character of the selected various forms of LV twisting into a systole and the ability of their transformation in the process of growth and development. This fact forms the basis of the author's original hypothesis of “the evolution of LV twisting models”, which provides the optimal ontogenetic growth of the child and adolescent heart in the postnatal period. The hypothesis of “evolution of left ventricular twisting types” is based on modern knowledge about multifaceted processes at the tissue level, the mechanics of LV in the individual rate of development and growth of the heart in childhood and adolescence.

The study aimed to determine the effect of lactic acid bacteria, fermentation time, and pressurized heating-cooling cycle on the formation of resistant starch content of beneng taro (Xanthosoma undipes K. Koch) flour. The materials used were beneng corm, isolates of lactic acid bacteria Lactobacillus casei and Streptococcus thermophilus, and MRSB media. The experimental design was randomized block design factorial with two factors: fermentation time (0, 18, and 24 hours) and pressurized-cooling heating (1, 2, and 3- cycles) in 3 replicates. The data were analyzed using analysis of variance and if necessary continued with Duncan's Multiple Range Test at a level of 95%. The tested parameters were the content of resistant starch, amylose, and amylopectin and the data were treated using variance of analysis. The results showed that the combination of L. casei and S. thermophillus produced the highest resistant starch content of 5.66%. Fermentation time of 18 and 24 hours produced resistant starch content of 4.46% and 4.51%, respectively. Autoclaving-cooling of 1-, 2-, and 3-cycle produced a similar type of resistant starch of 3.81%, 4.26%, and 4.16%, respectively. Therefore, the combination of L. casei and S. thermophillus fermented in 18 hours and 1-cycle of autoclaving-cooling is recommended to produce resistant beneng taro flour starch content.

Nitrogen (N) fertilizer of the urea type is very commonly used in Indonesia. The demand for this fertilizer is expected to increase, so an alternative is needed as a complement. Ammonium chloride (NH4Cl) is a by-product produced in the soda ash industry. This compound contains 26% N, which can be an alternative source of N nutrients for plants. The level of the following element, namely chlorine (Cl), is relatively high, so it is a concern that might affect the plant growth. This field experiment aimed to evaluate the effect of the application of ammonium chloride combined with potash fertilizers on the growth, production, and uptake of N and Cl nutrients in sweet corn plants. The trial was designed in a randomized group with nine treatments of 0%, 100%, 150%, and 200% N, combined with potassium sources from KCl and K2SO4. As a comparison, the source of N is urea at a dose of 100% N is referred to as the standard N treatment. Parameters observed included plant height, the weight of corn cobs and corn stover, N and Cl nutrient uptakes in seeds, leaves, and stems. The results showed that the application of ammonium chloride combined with different K sources markedly affected plant height, cob and plant stover weight, and N and Cl uptakes of sweet corn compared to controls. Applying N-ammonium chloride with KCl and K2SO4 showed no significant effect in growth and yield compared to standard N. The N dose showed no significant effect on plant growth and yield compared to the standard N dose.

Parabolic motion is the curved motion of an object whose trajectory is a
parabola. In objects that experience parabolic motion, objects will experience the
farthest distance and the highest point. The farthest distance traveled by an object in
motion with a parabolic trajectory is influenced by the elevation angle formed, this is
because the velocity in the direction of the x-axis and the velocity in the direction of
the y-axis are affected by the magnitude of the angle of elevation formed. The purpose
of this study is to analyze the motion of the parabola on the volleyball serve with a
variety of different angles so that volleyball players can find out the ideal angle for
the under serve so that the ball can fall on target and over the net. This research is
using experimental method. The results of a good and ideal angle when serving under
a volleyball so that the ball falls on target and crosses the net using an initial angle of
600, a falling angle of 250, and with a speed of 11.2 m/s which is analyzed using a
tracker.

Development of an in vitro protocol to induce artificial white spot lesions and their characterization using optical coherence tomography and micro CT
Authors: O'Hagan-Wong Kelsey , Enax Joachim , Meyer Frederic , Bozec Laurent , Ganss Bernhard 
Published: April 2023

Abstract
Background
White spot lesions (WSL) represent the earliest stage of caries formation in which mineral is lost from the enamel surface, but the surface retains its integrity. At this stage, remineralization of enamel is generally considered possible. This study aimed to develop a reliable in vitro protocol for the creation of artificially induced WSL and to examine the WSL by micro-computed tomography (microCT) and optical coherence tomography (OCT).
Methods
Artificial WSL lesions were created by immersing human molars in a lactic acid solution under constant agitation at 37ºC for seven days. MicroCT and OCT were used to image the lesions before comparing them to naturally occurring WSL. In addition, the mineral density of the demineralized enamel and the depth of the lesion was characterized directly on the acquired images.
Results
The average mineral density of artificial WSL was 1.57 ± 0.21 g/cm3, compared to sound enamel with a mean mineral density of 2.9 ± 0.06 g/cm3. The mean lesion depth of 167.76 ± 0.03 µm for artificial WSL varied slightly between individual samples. The artificial WSL did have a highly mineralized surface overlying the body of the lesion, which is characteristic of subsurface lesions; however, the lesion itself was shallower when compared to naturally occurring WSL. The OCT also detected WSL and provided an estimate of lesion depth and distance from
Conclusion
In summary, we have developed an experimental in vitro protocol to create artificial WSL that mimics natural caries lesions. OCT produced live scans, which allowed the detection of WSL, whereas the microCT measurements provided precise information on lesion depth and mineral density.
