Glutathione S-Transferase Contributes to the Resistance of Megalurothrips usitatus Against Lambda-Cyhalothrin by Strengthening Its Antioxidant Defense Mechanisms.

The damage caused by Megalurothrips usitatus, a common pest, has significantly affected the Chinese vegetable industry. The inappropriate application of chemical pesticides has caused M. usitatus to become highly resistant to conventional insecticides. Glutathione S-transferase (GST), known for its multifunctional properties, contributes to detoxification and antioxidation. It enhances insects' adaptability to pesticides by facilitating the elimination of lipid peroxidation products resulting from pyrethroid insecticides. This research employed RT-qPCR to identify GST genes that exhibited significant expression in response to lambda-cyhalothrin stress. It also quantified changes in antioxidant and apoptosis markers within the M. usitatus under lambda-cyhalothrin exposure. The functional significance of GST was validated by assessing alterations in the antioxidant defense system and resistance to lambda-cyhalothrin following the inhibition of GST activity. The study's outcomes indicated that MuGSTs1 was markedly upregulated in response to lambda-cyhalothrin stress (p < 0.0001). The GST activity was effectively suppressed by the specific inhibitor, diethyl maleate, achieving an inhibition rate of 64.05%. Following the inhibition of GST, the overall antioxidant capacity was reduced by 3.1-fold compared with the control, and the M. usitatus exhibited a 7.91-fold increase in sensitivity to lambda-cyhalothrin. These findings confirm the pivotal role of GST in the oxidative stress response of the M. usitatus and their contribution to the development of resistance to lambda-cyhalothrin through enhanced antioxidant defenses. This research offers valuable perspectives on the adaptive reactions of insects to chemical stressors, facilitating the management of resistance and the formulation of effective pest control strategies.

Advancing Chickpea Breeding: Omics Insights for Targeted Abiotic Stress Mitigation and Genetic Enhancement.

Chickpea is a major source of proteins and is considered the most economically vital food legume. Chickpea production is threatened by several abiotic and biotic factors worldwide. The main constraints limiting worldwide chickpea production are abiotic conditions such as drought, heat, salinity, and cold. It is clear that chickpea is treasured for its nutritive value, in particular its high protein content, and hence study of problems like drought, cold and salinity stresses are very important concerning chickpeas. In this regard, several physiological, biochemical, and molecular mechanisms are reviewed to confer tolerance to abiotic stress. The most crippling economic losses in agriculture occur due to these abiotic stressors, which affect plants in many ways. All these abiotic stresses affect the water relations of the plant, both at the cellular level as well as the whole-plant level, causing both specific and non-specific reactions, damage and adaptation reactions. These stresses share common features. Breeding programs use a huge collection of over 100,000 chickpea accessions as their foundation. Significant advancements in conventional breeding, including mutagenesis, gene/allele introgression, and germplasm introduction, have been made through this method. Abiotic tolerance and yield component selection are made easier by creating unique DNA markers for the genus Cicer, which has been made possible by developments in high-throughput sequencing and molecular biology. Transcriptomics, proteomics, and metabolomics have also made it possible to identify particular genes, proteins, and metabolites linked to chickpea tolerance to abiotic stress. Chickpea abiotic stress tolerance has been directly and potentially improved by biotechnological applications, which are covered by all 'Omics' approaches. It requires information on the abiotic stress response at the different molecular levels, which comprises gene expression analysis for metabolites or proteins and its impact on phenotype. Studies on chickpea genome-wide expression profiling have been conducted to determine important candidate genes and their regulatory networks for abiotic stress response. This study aimed to offer a detailed overview of the diverse 'Omics' approaches for resilience's to abiotic stresses on chickpea plants.

Methods for Selective Gene Expression Profiling in Single Tertiary Lymphoid Structure Using Laser Capture Microdissection.

Tertiary lymphoid structures (TLS) are de novo lymphoid formations that are induced within tissues during inflammatory episodes. TLS have been reported at various anatomic sites and in many different contexts like cancer, infections, autoimmunity, graft rejection, and idiopathic diseases. These inducible, ectopic, and transient lymphoid structures exhibit the prototypical architecture found within secondary lymphoid organs (SLO) and have been increasingly recognized as a major driver of local adaptive immune reaction. As TLS emerge within tissues, the isolation in situ and the molecular characterization of these structures are challenging to perform. Laser capture microdissection (LCM) is a powerful tool to isolate selective structural components and cells from frozen or paraffin-embedded tissues. We and other groups previously applied LCM to decipher the molecular network within TLS and uncover their intrinsic connection with the local microenvironment. In this chapter, we describe a detailed LCM method for selecting and isolating TLS in situ to perform comprehensive downstream molecular analyses.

Knowledge effects of action-related reactions to errors

Adaptive action-related reactions to errors, i.e. (meta-)cognitive processes and behaviours directly aimed at overcoming an error, have been proposed to benefit learning outcomes. However, causally interpretable findings are sparse in the current literature. Addressing this research deficit, the present study aimed at investigating whether action-related error adaptivity during the learning process facilitates knowledge acquisition in an actual learning situation. Data of 177 undergraduate students was analysed in structural equation models. Adaptive action-related reactions to errors were simultaneously assessed via self-reports and a behavioural indicator (voluntary repetitions of previous learning material after errors). Both forms of operationalisation were positively correlated and revealed similar result patterns. In two separate models, self-reported as well as behavioural adaptive action-related reactions to errors indicated a positive effect on knowledge acquisition. These findings further validate the self-report measurement of action-related error adaptivity and point to its direct impact on the learning outcome.

Objective. To study the quality of life and adaptation of elderly men and women with chronic cerebral ischemia.Materials and methods. The study included 65 patients (31 men and 34 women, mean age 81.6±1.1 years) diagnosed withchronic cerebral ischemia. The assessment of quality of life carried out by using the Russian version of the general questionnaire “SF-36 HEALTH STATUS SURVEY”. The level of asthenia studied using the MFI-20 questionnaire. Levels of anxiety and depression were determined using the HADS scale. Adaptive reactions studied in the leukocyte blood count by calculating the percentage of lymphocytes and segmented neutrophils.Results. The patients rated their quality of life low in all areas, including the areas of physical capabilities, psychological well-being and social activity. A high prevalence and varying degrees of severity of asthenia, anxiety and depressive disorders revealed in all patients, more pronounced in women. The formation of homeostatic blood reactions was observed, indicating a decrease in the level of adaptation.

Error Climate and Gender as Factors Influencing Error Reactions in Primary School Children

Errors can support learning processes when students react to errors on an affectivemotivational adaptive and action-adaptive level. Empirical findings indicate that these adaptive reactions to errors are influenced, among others, by the error climate in the classroom as an overarching factor of different dimensions. There is further evidence that there are gender differences in student reactions to errors and that these are differently associated with the dimensions of the error climate. Less is known about the interaction between these variables and whether there are gender-specific differences in adaptive reactions to errors, specifically in primary schools. The aim of the study was to replicate findings on the relevance of error climate as an overarching factor and its dimensions for adaptive reactions to errors in primary school children. The study also investigated gender differences in student perceptions of the error climate, which may explain gender differences in students' adaptive reactions to errors. The sample encompassed third and fourth graders (N=675). Analyses at both the individual and class levels replicated findings from the secondary level for the primary level and revealed further gender-specific differences in student learning from errors that were associated with gender differences in primary school children’s perception of the error climate.

Activation of the general stress response sigma factor SigB prevents competence development in Bacillus subtilis.

Bacillus subtilis exhibits a large number of different specific and general adaptation reactions, which need to be well balanced to sustain survival under largely unfavorable conditions. Under specific conditions, natural competence develops, which enables B. subtilis to actively take up exogenous DNA to integrate it into its own genome. In contrast to this specific adaptation, the general stress response is induced by a variety of exogenous stress and starvation stimuli, providing comprehensive protection and enabling survival of vegetative B. subtilis cells. In the present work, we reveal the molecular basis for the interconnection of these two important responses in the regulatory network. We describe that the master regulator of the general stress response SigB is activated by physiological stress stimuli, including daylight and ethanol stress, leading to the inactivation of the competence master regulator ComK by transcriptional anti-sense regulation, showing a strict hierarchy of adaptational responses under severe stress.

Novel dual-pathogen multi-epitope mRNA vaccine development for Brucella melitensis and Mycobacterium tuberculosis in silico approach.

Brucellosis and Tuberculosis, both of which are contagious diseases, have presented significant challenges to global public health security in recent years. Delayed treatment can exacerbate the conditions, jeopardizing patient lives. Currently, no vaccine has been approved to prevent these two diseases simultaneously. In contrast to traditional vaccines, mRNA vaccines offer advantages such as high efficacy, rapid development, and low cost, and their applications are gradually expanding. This study aims to develop multi-epitope mRNA vaccines argeting Brucella melitensis and Mycobacterium tuberculosis H37Rv (L4 strain) utilizing immunoinformatics approaches. The proteins Omp25, Omp31, MPT70, and MPT83 from the specified bacteria were selected to identify the predominant T- and B-cell epitopes for immunological analysis. Following a comprehensive evaluation, a vaccine was developed using helper T lymphocyte epitopes, cytotoxic T lymphocyte epitopes, linear B-cell epitopes, and conformational B-cell epitopes. It has been demonstrated that multi-epitope mRNA vaccines exhibit increased antigenicity, non-allergenicity, solubility, and high stability. The findings from molecular docking and molecular dynamics simulation revealed a robust and enduring binding affinity between multi-epitope peptides mRNA vaccines and TLR4. Ultimately, Subsequently, following the optimization of the nucleotide sequence, the codon adaptation index was calculated to be 1.0, along with an average GC content of 54.01%. This indicates that the multi-epitope mRNA vaccines exhibit potential for efficient expression within the Escherichia coli(E. coli) host. Analysis through immune modeling indicates that following administration of the vaccine, there may be variation in immunecell populations associated with both innate and adaptive immune reactions. These types encompass helper T lymphocytes (HTL), cytotoxic T lymphocytes (CTL), regulatory T lymphocytes, natural killer cells, dendritic cells and various immune cell subsets. In summary, the results suggest that the newly created multi-epitope mRNA vaccine exhibits favorable attributes, offering novel insights and a conceptual foundation for potential progress in vaccine development.

Designing novel multiepitope mRNA vaccine targeting Hendra virus (HeV): An integrative approach utilizing immunoinformatics, reverse vaccinology, and molecular dynamics simulation.

Human and animal health is threatened by Hendra virus (HeV), which has few treatments. This in-silico vaccine design study focuses on HeV G (glycoprotein), F (fusion protein), and M (matrix protein). These proteins were computationally assessed for B and T-cell epitopes after considering HeV strain conservation, immunogenicity, and antigenicity. To improve vaccination immunogenicity, these epitopes were selectively ligated into a multiepitope construct. To improve vaccination longevity and immunological response, adjuvants and linkers were ligated. G, F, and M epitopes were used to create an mRNA HeV vaccine. Cytotoxic, helper, and linear B-lymphocytes' epitopes are targeted by this vaccine. The population coverage analysis demonstrates that multi-epitope vaccination covers 91.81 percent of CTL and 98.55 percent of HTL epitopes worldwide. GRAVY evaluated the vaccine's well-characterized physicochemical properties -0.503, indicating solubility and functional stability. Structure analysis showed well-stabilized 2° and 3° structures in the vaccine, with alpha helix, beta sheet, and coil structures (Ramachandran score of 88.5% and Z score of -3.44). There was a strong affinity as shown by docking tests with TLR-4 (central score of -1139.4 KJ/mol) and TLR-2 (center score of -1277.9 KJ/mol). The coupled V-apo, V-TLR2, and V-TLR4 complexes were tested for binding using molecular dynamics simulation where extremely stable complexes were found. The predicted mRNA structures provided significant stability. Codon optimization for Escherichia. coli synthesis allowed the vaccine to attain a GC content of 46.83% and a CAI score of 1.0, which supports its significant expression. Immunological simulations indicated vaccine-induced innate and adaptive immune reactions. Finally, this potential HeV vaccine needs more studies to prove its efficacy and safety.

Adaptive responses of heart rate regulation during functional tests with breath holding

BACKGROUND: Synchronization of biorhythms in living organisms is of particular interest to researchers from the standpoint of adaptation theory. AIM: To study the characteristics of the response of regulatory influences on heart rhythm during tests with voluntary breath holding during inhalation and exhalation. MATERIAL AND METHODS: The study sample included 21 randomly selected students (9 males, 12 females) aged 20.64±1.14 years with body weight 67.19±12.98 kg, height 172.29±7.63 cm. All subjects were divided into three groups (I, II, III) according to the classification by N.I. Shlyk (2009), which is based on the predominance of central or autonomic circuits of heart rhythm regulation. A fivefold sequential ECG recording was conducted using the hardware-software complex “Varicard 3.0” with the subject seated after a five-minute rest: 1 — baseline state; 2 — voluntary breath holding during inhalation; 3 — resting state; 4 — voluntary breath holding during exhalation; 5 — resting state. Using the “Varicard 3.0” system, a mathematical analysis of heart rhythm was performed, taking into account statistical parameters of heart rhythm and indices of spectral frequency analysis. RESULTS: During the period of breath holding, heart rate variability decreased, while at rest it increased in all groups. In group I, after a breath-hold test during the rest period, eutonia was observed according to spectral analysis (HF=LF). Statistical analysis in this group demonstrated an increase in the contribution of the parasympathetic component to heart rate variability (RMSSD, pNN50, SDNN, CV), signifying the prerequisites for increased heart rate variability. In group II, after breath-holding tests, a slight decrease in sympathetic activity was observed. A tense pattern of autonomic regulation was observed during the exhalation breath-hold test, which may indicate a reduced functional state of the regulatory systems. Group III was characterized by a sharp increase in sympathetic activation in the test with breath holding during inhalation, followed by a soft correction during breath holding during exhalation, which can be regarded as an adequate response of the body to the load. At rest, after the test, the regulation pattern returned to the original one with a moderate predominance of parasympathetic activity and, accordingly, a more favorable level of heart rate variability for the body. CONCLUSION: Adaptive reactions of the heart rate variability are manifested by an increase in sympathetic activation, which, subsequently, during normal breathing, is replaced by a compensatory activation of the parasympathetic division of the autonomous nervous system. Although reactions are unidirectional, the severity can vary across the groups.

The Mediation Role of Coping With Stress in the Relationship Between Psychological Flexibility and Posttraumatic Growth in Cancer Patients.

Objectives: Active and adaptive coping strategies have been identified as factors that can assist cancer patients in effectively managing and overcoming the crisis, leading to the potential for post-traumatic growth during the diagnosis and treatment stages. Psychological flexibility is another factor that can protect individuals and promote more adaptive reactions to traumatic situations. The study aims to examine the investigation of the mediation role of coping with stress in the relationship between psychological flexibility and posttraumatic growth in cancer patients. Methods: This study was conducted with 97 (63 women, 34 male) participants aged between 38 and 82 who are literate and diagnosed with breast cancer or gynecological cancers (endometrial, cervical, vulvar) undergoing radiotherapy planning at the Radiation Oncology Clinic of Zonguldak Bülent Ecevit University Hospital. Demographic Information Form, Psychological Flexibility Scale, Post-Traumatic Growth Inventory, and Coping Styles Scale were applied to the participants. The mediation effects were interpreted using bootstrap confidence intervals and VAF values. Results: This study showed that the active coping styles partially mediated the relationship between psychological flexibility and posttraumatic growth. Conclusion: In this regard, by organizing psychoeducational programs and interventions aimed at increasing psychological flexibility for individuals diagnosed with cancer or undergoing treatment, individuals can be enabled to cope with stress more actively, and thus post-traumatic growth can be achieved.

Is There a Role for Immunostimulant Bacterial Lysates in the Management of Respiratory Tract Infection?

Bacterial Lysates are immunostimulants clinically prescribed for the prevention of respiratory tract infections (RTIs). It has been shown that Bacterial Lysates upregulate the immune system, acting both on innate and adaptive reactions. In fact, there are demonstrations of their efficacy in restoring the integrity and immune function of epithelial barriers, activating ILC3 and dendritic cells with an enhanced Th1 response, and producing serum IgG and serum and salivary IgA specific to the administered bacterial antigens. The activated immune system also protects against other bacteria and viruses due to a trained immunity effect. Most studies show that the number of RTIs and their severity decrease in Bacterial Lysates-pretreated patients, without relevant side effects. The Bacterial Lysates treatment, in addition to reducing the number of RTIs, also prevents the deterioration of the underlying disease (i.e., COPD) induced by repeated infections. Despite these positive data, the most recent meta-analyses evidence the weakness of the studies performed, which are of low quality and have an inadequate number of patients, some of which were non-randomized while others were without a control group or were performed contemporarily in different clinical conditions or with different ages. The high heterogeneity of the studies does not allow us to state Bacterial Lysates' effectiveness in preventing RTIs with sufficient certainty. To completely define their indications, double-blind, placebo-controlled, multicenter, randomized clinical trials should be performed for each product and for each indication. The study population should be adequate for each indication. For this purpose, an adequate run-in phase will be necessary.

The authors analysed the state of the immunohaematological profile. For qualitative and quantitative adaptation reactions characterisation of the organism, leukocyte blood indexes were calculated. The results of the study have allowed to determine the main markers of impaired immunological reactivity in animals kept in territories with unfavourable environmental conditions.

Влияние регуляторного пептида тафтцин-pro-gly-pro на показатели вариабельности ритма сердца крыс в условиях различной физической активности

Background: The cardiotropic effects of a synthetic peptide with the anxiolytic activity of taftsinPro-Gly-Pro (taftsin-PGP) under stress was investigated. Previously, the effect of this peptide on the state of the cardiovascular system, which plays an important role in the adaptive reactions of the body under stress, has not been studied. The aim of the study: To study the effect of the regulatory peptide taftsin-Pro-Gly-Pro on the heart rate variability (HRV) indices of rats under conditions of various motor activity. Materials and methods: The study was performed on 48 Wistar rats. HRV indices were recorded using the Physiobelt 2.5.1 complex (Neurobotics, Russia) and analyzed by statistical, geometric and spectral indicators. Taftsin-PGP was administered intraperitoneally at doses of 80, 250 and 750 μg/kg once in a volume of 1 μg/kg. The study was performed in 4 stages: 1 – after adaptation to the device (before the introduction of the peptide), 2 – 15 minutes after the introduction of the peptide, 3 – after physical exertion (2-minute treadmill run), 4 – after a 15-minute rest. Results: At a dose of 80 μg/kg, taftsin-PGP had a pronounced adaptogenic effect in the form of maintaining the initial level of functioning of regulatory mechanisms both during physical exertion and during recovery. At a dose of 250 μg/kg, taftcin-PGP led to disorganization of autonomic regulation at the level of the autonomous and central circuits of heart rate regulation. The introduction of the peptide at a dose of 750 μg/kg stabilized the mechanisms of regulation of heart rate with increased physical activity, but caused an imbalance in the regulation of heart rate during recovery. Conclusion: Intraperitoneal administration of taftsin-PGP to Wistar rats had a dose-dependent and multidirectional effect on the regulation of heart rate at all stages of the experiment: at rest (15 minutes after administration), after physical exertion and during recovery.

Tezepelumab: a promising therapy for severe uncontrolled asthma

Asthma is a complex inflammatory airway disease affecting a significant global population, spanning from childhood through adulthood. Despite advances in treatment modalities, a significant subset of patients, approximately 10%, grapple with severe asthma, characterized by increased healthcare utilization and diminished quality of life. Tezepelumab, a monoclonal antibody targeting thymic stromal lymphopoietin (TSLP), offers promising therapeutic potential. TSLP is a protein released by a variety of cells, with a predominance of epithelial cells, in reaction to plenty of stimuli, such examples as viruses, aeroallergens, and others. Its action is upstream and pertains to initiating numerous subsequent innate and adaptive immune reactions, contributing to the continuation of asthma pathophysiological processes. Tezepelumab’s unique efficacy spans diverse severe asthma phenotypes, significantly reducing exacerbation rates across eosinophilic and non-eosinophilic subtypes. Its favorable safety profile and clinically meaningful improvements in asthma control, accompanied by reductions in cytokine levels and baseline biomarkers, underscore its broad impact on asthma inflammation. Its efficacy, irrespective of type 2 (T2) endotype, reinforces the idea that TSLP blockade broadly inhibits pathways crucial to asthma pathophysiology, rather than narrowly focusing on individual downstream factors, as previous biological treatments have. This review discusses the rationale for TSLP blockade and the efficacy of tezepelumab in severe asthma using data from key trials.

ADAPTATION OF NAVAL PENTATHLON ATHLETES TO PHYSICAL TRAINING

Rationally planned training leads to adaptation and progress, and irrational planning leads to disruption of the course of adaptation reactions and overwork. For a rational periodization it is very important to identify training concepts based on detailed analysis of fatigue development mechanisms. Proper planning and execution of training will result in an increase in effort capacity. Adaptation, viewed from a biological point of view, is a complex defense mechanism against the demands caused by environmental changes. This requires an adequate response of the organism to environmental conditions in order to survive under the new conditions. For sports training, adaptation refers to the set of transformations that the athlete's body undergoes in training, in order to develop a superior state of bio-psycho-motor balance, materialized in the easy execution of a task. Research objectives: Initial evaluation of subjects; Development of the training program; Evaluation of the level of adaptation to physical effort obtained from specific naval pentathlon training; Development of a training planning model, allowing the improvement of physical effort capacity by means specific to the naval pentathlon. Methods: The research carried out started from the premise that the appropriate use of training means specific to the naval pentathlon can lead to an improvement of the effort capacity of military students, which fully satisfies their performance needs in fulfilling combat missions arising from the graduate's model. At a preliminary stage of the research, by applying general physical training tests, we obtained an initial assessment of the research subjects. These data were a benchmark in developing the training program and setting effort parameters. The training plan thus designed contains training sessions specific to naval pentathlon trials, adapted to the normal conditions of the naval academy training process. Results: The comparative analysis of the results, based on mathematical-statistical and graphical methods, reveals significant increases in performance recorded in the final testing stage. The dynamics of the results demonstrates a significant evolution of the results of the experimental group carried out during the training program, carried out according to the designed model. This confirms to us the effectiveness of applying the training program. The statistical results confirm a very good evolution of the results for the general motor tests and for the Ruffier test. Conclusions: Regular exercise is a particularly important stimulus for adaptation. Sports training, by its specific means, aims to increase the level of performance. In order to achieve this objective, it is necessary to apply a well-defined programme in great detail. Effective training requires constant variability in programming. In addition, in order to maximize the positive transfer of training, the means used in the training lesson should be as close as possible to the characteristics of the effort. Because of this, there is a permanent conflict in training programming, between diversity and specificity. This conflict can only be successfully managed through professional intervention on the part of the coach and involvement of the athlete according to training requirements.

Understanding Family Reactions to Transgender Children in Iranian Culture: A Qualitative Study.

The family plays a crucial role in shaping children's identity and understanding of gender-based roles. This study aims to explore the experiences of Iranian transgender individuals with their families' reactions to their transgender identity disclosure. In 2018, nurse researchers conducted this qualitative study on 11 transgender individuals in Iran using a phenomenological approach, targeted and snowball sampling, and Colaizzi's seven-step method for data analysis. Rigor was ensured by adhering to Lincoln and Guba's standards. The study found varied reactions to transgender children among Iranian families, including abuse to avoid stigma. The study revealed two main themes, maladaptive and adaptive reactions, and identified six categories: denial of reality, mourning, coercion, deprivation, support out of necessity, and compromise of family reactions. Education and support systems may help address the cultural challenges that face families with transgender children. The findings offer insights for enhancing public awareness of the transgender community in conservative cultures.
