Published: October 2024

Relevance. The creation of high-quality oilseed flax seeds using new plant breeding methods is an imperative principle with the advent of better crop seed production. Current methods for creating such seeds continue to be complicated and laborious. In this regard, the development of more advanced methods for obtaining renewed seeds with a high level of manifestation of sowing, various types and morphophysiological properties is relevant and has practical importance.Methods. The experiments were carried out in accordance with the methods of planting, conducting field experiments with flax, and methodological recommendations for seed production of oil flax. The assessment of sowing quality and seed material was carried out in accordance with the current certification system , varietal quality — by the soil control method.Results. The high efficiency of creating updated oilseed flax seeds using the method of plant selection during the growing season — from the beginning to the end of full flowering, which allowed for a significant increase in their yield to 61.5%, compared with the control. Selection of plants in the interval from the beginning to the end of full flowering ensured the preservation of the sowing qualities of the created seeds at the control level — selection according to the current method, as well as increasing the uniformity of indicators of the morphophysiological properties of seeds, including the uniformity of seed sprouts along the length by 4.6%. The selection method with the removal of plants atypical in morphological charakteristics compared with the control allowed to increase the yield of updated oilseed flax seeds by 29.7%, improve their morphophysiological properties. The varietal quality of the updated seed material for all methods of its creation was characterized by the absence of atypical seeds in color and minor differences between the options in the uniformity of varietal characteristics.

Published: October 2024

One of the main agrotechnical activities carried out in the garden is tree pruning. When studying the variety-double combinations of apple trees in certain environmental conditions, it is necessary to take into account the strength of growth, the density of fouling, the type of branching, the structure of fruit formations, which depends on the varietal characteristics and technologies of growing plantations.The author presents the results of studying the parameters of the influence of the degree of pruning of Golden Delicious apple trees grafted on low-growing rootstocks SK-7 and M-9, depending on the rootstock, on growth processes, productivity and marketable qualities of apple fruits. The reaction of plantings to pruning was determined depending on the biological characteristics of the variety and on the degree of branch removal and their orientation. With an increase in the intensity of pruning, the leaf surface area per fruit on the rootstock SK-7 was 180–750 cm², on the rootstock M-9 — 172–619 cm², respectively. The yield of apple trees from one tree on the rootstock SK-7 was 13.2 kg with a minimum shape, 11.4 kg with an average, 10.5 kg with a maximum, and 11.4 kg, 9.5 kg and 7.7 kg on the rootstock M-9, respectively. The average weight of fruits grafted on the rootstock SK-7 increased by 1.9 times, and on the rootstock M-9 — by 1.3 times.It was noted that the life cycles of trees on the low-growing dwarf rootstock SK-7 were 10–12% higher than on the rootstock M-9.

Published: October 2024

La distrofia miotónica tipo 1 (DM1) congénita es una entidad poco frecuente que puede suponer un reto diagnóstico, especialmente si coexisten otros procesos como la prematuridad.Objetivo: Describir un caso clínico de presentación típica de DM1 congénita, y aumentar así la sospecha diagnóstica.Caso Clínico: Recién nacida pretérmino de 29 semanas que precisó ventilación mecánica no invasiva hasta la semana 41 de edad postmenstrual, presentando apneas que se manejaron con ventilación manual con bolsa autoinflable y masaje cardiaco. Inicialmente se atribuyeron a la prematuridad. Sin embargo, la paciente presentaba hipotonía, hiporreflexia, retracción aquílea bilateral, diplejía facial y succión débil, características que junto con el compromiso respiratorio, orientaban a una enfermedad neuromuscular. Como antecedentes destacaba infertilidad en la madre y polihidramnios durante la gestación. En la exploración dirigida a la madre presentaba miotonía clínica, confirmada posteriormente en el electromiograma, lo que orientó a una distrofia miotónica congénita. Se confirmó genéticamente encontrándose 2000 copias CTG en la recién nacida y 833 en su madre.Conclusiones: Las apneas y compromiso respiratorio en un recién nacido hipotónico y débil son una manifestación frecuente de esta enfermedad. La presencia de miotonía en la madre de un recién nacido con sospecha de enfermedad neuromuscular orienta a DM1 congénita. Este caso destaca la importancia de la anamnesis y exploración exhaustiva a la paciente y su madre como elementos claves en la orientación diagnóstica etiológica.

Published: October 2024

The objective of this study is to identify and explain the patterns of parental and peer support in shaping anti-bullying behaviour among students at SMPK Citra Bangsa Mandiri Kupang. Bullying is a persistent and repetitive form of aggressive behaviour characterised by an unequal power dynamic between the offender and the victim, with the intention of causing harm and exerting pressure on the victims. This study employs descriptive methodologies with a qualitative approach, utilising interview techniques. This buy is mostly aimed for the eighth grade children. The study involved a total of four participants, comprising two parents and two students. Interviews are systematically done to examine the influence of school programmes on the development of anti-bullying behaviour through observation. The study findings indicate the existence of three distinct forms of parental support in shaping children' anti-bullying behaviour. The concept of Conscious Parenting is the deliberate and mindful approach of raising children, with a strong emphasis on attentive care and effective communication. Authoritative Parenting, the second style, is distinguished by parents who make fair requests and have high levels of responsiveness towards their children. Parents who have been given official permission not only have elevated standards for their children, but also provide them with the necessary resources and assistance to achieve success.

Published: October 2024

BackgroundMesenchymal stem cells (MSCs) are safe and effective in treating myocardial infarction (MI) and have broad application prospects. However, the heterogeneity of MSCs may affect their therapeutic effect on the disease. We recently found that MSCs derived from different segments of the same umbilical cord (UC) showed significant difference in the expression of genes that are related to heart development and injury repair. We therefore hypothesized that those MSCs with high expression of above genes are more effective to treat MI and tested it in this study.MethodsMSCs were isolated from 3 cm-long segments of the maternal, middle and fetal segments of the UC (maternal-MSCs, middle-MSCs and fetal-MSCs, respectively). RNA-seq was used to analyze and compare the transcriptomes. We verified the effects of MSCs on oxygen-glucose deprivation (OGD)-induced cardiomyocyte apoptosis in vitro. In vivo, a rat MI model was established by ligating the left anterior descending coronary artery, and MSCs were injected into the myocardium surrounding the MI site. The therapeutic effects of MSCs derived from different segments of the UC were evaluated by examining cardiac function, histopathology, cardiomyocyte apoptosis, and angiogenesis.ResultsCompared to fetal-MSCs and middle-MSCs, maternal-MSCs exhibited significantly higher expression of genes that are associated with heart development, such as GATA-binding protein 4 (GATA4), and myocardin (MYOCD). Coculture with maternal-MSCs reduced OGD-induced cardiomyocyte apoptosis. In rats with MI, maternal-MSCs significantly restored cardiac contractile function and reduced the infarct size. Mechanistic experiments revealed that maternal-MSCs exerted cardioprotective effects by decreasing cardiomyocyte apoptosis, and promoting angiogenesis.ConclusionOur data demonstrated that maternal segment-derived MSCs were a superior cell source for regenerative repair after MI. Segmental localization of the entire UC when isolating hUCMSCs was necessary to improve the effectiveness of clinical applications.
Dynamics of optical properties of sequentially diluted lucigenin aqueous solutions according to luminescence data

Published: October 2024

The article discusses optical properties (luminescence) of diluted (24 dilution factor) lucigenin (Lc) aqueous solutions. Six series of Lc aqueous solutions, with 50 samples in each series, were studied. The series were diluted on different days within random schedules, following a unified procedure: the first sample in all the series was the Lc (CLc = 8.2 × 10−7 mol/L) stock solution, while the rest of the samples were obtained by successive dilution with the ratio of 24. For the first three samples, the Lc luminescence intensity decrease appropriately complied with the exponential function model (the dilution ratio: none for the stock solution, for the second and the third, 24 and 24 × 24 = 242, respectively). Starting from the fourth sample for statistical processing of luminescence data, the seven largest values were selected from the built rank distribution of emission intensity values. This method helps eliminate the influence of “random large bounces” when calculating the correlation coefficient. Up to the 50th studied sample, a challenging linear gradual decrease in the intensity of recorded photometric values was noted (correlation coefficients for all series being close to −0.9). Similar analysis of six reference series of pure water “dilution” samples did not exhibit any correlation between the highest emission values in the studied wavelength range (specific for Lc bandwidth, 480–505 nm) and the sample’s dilution number. It can be assumed that photometric values, recorded in the series of Lc sequentially diluted aqueous solutions after substance (Lc) elimination (theoretically expected after the 13th sample within the used experimental setup), could be attributed to the gradual destruction of long-lived aqueous structures formed in the process of hydration of Lc molecules during its dissolution.
