Edentulism, a condition characterized by the absence of teeth, significantly impacts facial aesthetics, eating efficiency, and speech fluency, thereby diminishing the quality of life. This paper aims to explore the All-On-Four Treatment Concept in Dental Implants, a promising solution to this issue. The All-On-Four approach, though complex, offers a pathway to restore smile and functionality by using four strategically positioned implants to hold a temporary prosthesis. This prosthesis is later replaced by a permanent version after approximately four months. This swift oral restoration technique significantly enhances a patient’s self-confidence and overall life quality. The significance of this treatment lies in its potential to provide a less invasive and more affordable solution for severe jawbone atrophy, where the proximity of critical anatomical structures and compromised bone conditions may hinder other prosthetic solutions. The paper concludes with a discussion on the potential of the All-On-Four treatment to revolutionize dental implant procedures, offering a beacon of hope for individuals suffering from edentulism.

Background: Myxedema is an extreme manifestation seen in patients with untreated hypothyroidism. It is a lethal endocrine emergency, which arises when a precipitating cause overwhelms the compensatory mechanisms of the hypothyroid state.Objectives: This case report aims to present a case of myxedema coma secondary to cretinism. It also aims to discuss how hypothyroidism leads to hypoventilation and eventually respiratory failure, as well as to discuss the epidemiology, pathophysiology, clinical manifestation, diagnosis, and management of a child with myxedema coma.Case presentation: This is a case of a 7-year-old female, diagnosed with congenital hypothyroidism at 5 months of age, but eventually was lost to follow-up. She came back after 7 years presenting with difficulty of breathing. She was seen hypothermic, obtunded, and in severe respiratory distress. She was severely stunted and underweight with coarse facial features. Initial laboratory work-up showed elevated Thyroid Stimulating Hormone (TSH) as well as decreased tri-iodothyronine (FT3) and thyroxine (FT4). She was immediately started on levothyroxine, with noted resolution of the edema and improvement in sensorium. There was also noted improvement in the patient’s ventilation and was sent home on Continuous Positive Airway Pressure (CPAP) while asleep.Conclusion: This case highlights the importance of having a high index of suspicion of its clinical manifestations, which could lead to earlier intervention thereby preventing further complications. A multidimensional approach is essential in managing this case, as various organ systems are involved in this condition.

Introduction: Aluminum Phosphide (AlP) poisoning is a life-threatening condition that commonly occurs in developing countries, often resulting in cardiac, respiratory, and metabolic complications, leading to multi-organ failure and mortality. Extracorporeal Membrane Oxygenation (ECMO) has been proposed as a potential therapy for severe AlP poisoning cases refractory to conventional management, though its use remains controversial. Methodology: for this literature review, we conducted a comprehensive analysis of existing literature concerning the utilization of ECMO in patients with severe AlP poisoning. We meticulously examined available publications to explore the relationship between ECMO initiation and patient outcomes. Discussion: The review reveals that early ECMO initiation within 6 hours of presentation is associated with better outcomes and higher survival rates in severe AlP poisoning cases. However, uncertainties persist regarding the optimal timing and duration of ECMO support, and potential complications, including bleeding, acute renal injury, and ventilator-associated pneumonia, need careful consideration. Conclusion: Despite promising results in certain cases, the risks and benefits of ECMO in AlP poisoning require meticulous evaluation. Ethical considerations, encompassing resource allocation and implications for other patients, necessitate appropriate patient selection criteria.

Background: Human Immunodeficiency Virus (HIV) and thyroid function have been described. Prevalence pattern and atherogenic status significantly differ from HIV-negative control in several studies. Unfortunately, few studies have determined the prevalence of thyroid function and lipids among Nigerians living with HIV. Objective: This study is to evaluate thyroid hormones and lipid profiles in HIV-positive subjects attending a faith-based health facility in Anambra State Nigeria.Materials and methods: The serum concentration of Thyroid Stimulating Hormone (TSH), free Triiodothyronine (fT3), triiodothyronine (T3), free Thyroxine (fT4), Thyroxine (T4), Total Cholesterol [TC], Triglyceride [TG], High-Density Lipoprotein [HDL], Low-Density Lipoprotein [LDL] and Very Low-Density Lipoprotein [VLDL] was determined in 95 HIV positive subjects which include 48 patients who were on HAART- group 1 and 47 not on HAART- group 2; and compared to 30 HIV negative controls – group 3. Results: The level of TSH and fT3 was significantly (p < 0.05) higher in group 1 participants than in group 2 and the group 3 participants. The level of T4 was significantly higher in group 2 than in group 1 and group 3 participants. The level of T3 was significantly lower in Control participants in comparison to both HAART and non-HAART participants. The prevalence of fT4 dysfunction across the groups was significantly different from each other. The total mean of Cholesterol (163.5 ± 22.7), Triglyceride (163.5 ± 22.7), and Very Low-Density Lipoprotein (14.2 ± 2.4) of the HIV-positive participants were significantly (p < 0.05) lower than that of the HIV negative participants.Conclusion: The results obtained from this study indicate that serum levels of thyroid hormones may be used as baseline periodic markers during antiretroviral therapy and many people living with HIV may benefit from supplementation if appropriate.

Introduction: Nursing theories are critical as they drive nursing education, practice, and research. Neuman Systems Model (NSM) considers a person a complete system with integrated psychological, physiological, spiritual, social, and developmental components. Nurses give their patients physical, emotional, and psychological assistance and are subjected to mental and physical pressure due to these responsibilities, impacting their health, psychological well-being, and interpersonal relationships. This paper aims to perform a concept analysis of stressors proposed in NSM about lines of defense and the level of preventive interventions that can affect a person’s well-being. Further, this paper discusses knowledge generation through NSM’s applicability to preventing exhaustion and burnout among nurses. Methodology: This theoretical attempt is carried out using the theory analysis approach suggested by Walker and Avant (2019).Discussion: Nursing is a career that requires a great deal of dedication and personal engagement. Nurses are subjected to recurrent stresses due to technological advances and rising demands. Burnout occurs when nurses get discouraged and have less compassion for the patients due to recurrent burdens. Stress and burnout are two of the most common reasons for nurses to quit hospitals. The NSM is concerned with stresses that may affect a person’s health and well-being (prediction). Nurses assist patients at the most vulnerable and challenging times, such as surgical procedures, traumas and personal and physical losses.Conclusion: The NSM enables the investigation of preventative and protective treatments. Because of the model’s flexibility, it may be used in a wide range of nursing situations. Administrative, hospitals, clinics, and other nurses can benefit from this paradigm. Evaluating the many distinct elements contributing to burnout is also feasible. The model’s client factors of physiological, sociocultural, developmental, and spiritual characteristics are used to achieve this. Viewing the individual as an open system that responds to environmental stimuli encourages the existence of stressors that might lead to burnout.

The present study focuses on students and teachers in Swedish Municipal Adult Education, in a project aimed at helping students with diagnoses within the neuropsychiatric spectrum. The project aimed to support students to complete their studies for further higher education. As this is an overlooked group of students research results provide insights into students’ views on the project and conclusions regarding the sustainability of school development. In this qualitative study, five teachers and four teachers were observed and in-depth interviewed. Data were analyzed through inductive content analysis. Authentic relations between students and teachers, signified by mutual trust, proved important. As the teachers themselves had originated the ideas guiding the project, the development work had good prior conditions for further sustainable development.  We conclude that autonomous teachers, who set up joint goals and provide individualized support for these students, enable academic success when flexibility, relations, and self-esteem characterize the work.

Background: Breast Cancer is the most common cancer in women and the quality of life of women with breast cancer is a significant healthcare issue specifically in developing and underdeveloped countries.Globally quality of Life (QoL) has become an important indicator to measure the outcomes of medical and nursing interventions. The QoL studies have an imperative role in healthcare especially in chronic disease as the latest diagnostic and treatment modalities have increased the survival rates and duration of cancer patients. Similarly, breast cancer itself and its treatment with Chemotherapy, in particular, has many complications and negative impacts on the QoL of cancer women. Aim: The aim of this study was to assess the QoL of Pakistani women with Breast Cancer patients undergoing chemotherapy and the relationship of QoL with socio-demographic variables.Methodology: A descriptive cross-sectional correlational study was conducted on 110 female breast cancer patients undergoing chemotherapy. FACIT-B questionnaire was used to assess the quality of life of these patients. Statistical analysis was done by using SPSS version 20 using the Pearson correlation coefficient, Chi-square test, and Spearman’s rho correlation coefficient. Results: The mean age of participants was (mean ± SD) 42.98 ± 8.98. A significant negative correlation was observed with age and QoL, r = -0.218, p - value 0.022. No significant association was observed between QoL and marital status; education status; and socioeconomic status.Conclusion: The majority of breast cancer women 59(53.6%) had moderate QoL and Chemotherapy also showed moderate impacts on different domains: physical, functional emotional, social, and sexual well-being of the women.

Background: Early childhood caries may develop as soon as teeth erupt. Promoting oral health care programs is very important and helps to reduce dental caries in young children. The aim of this study was to assess the infant/child oral health (IOH) related knowledge, attitudes, and practices (KAP) of parents in Riyadh, Saudi Arabia. Materials and Methods: A cross-sectional descriptive study was conducted among 327 parents. Visiting the family medicine center at prince sultan military medical city, Riyadh Saudi Arabia. A 39-item questionnaire covering socio-demographic characteristics and questions pertaining to KAP regarding OH care will be used to collect the data. Descriptive statistics, Student’s t-test, one-way analysis of variance, and Scheffe’s test will use for the statistical analysis (p ≤ 0.05). Results: The result showed that the majority of the parents had good knowledge regarding OH, knowledge of cleaning (92.4.%), and knowledge of the amount of sugar (88.1.%). the parent’s age group (30 to 39) years (n =147) reported the highest mean (knowledge, attitudes, and practice) scores among all other age groups with a knowledge mean score of (6.80 ± 1.73), an attitude mean score of (8.86 ± 1.37), and a practice mean score of (5.14 ± 1.86).  Female parents showed significantly higher mean knowledge, attitude, and practice scores than male parents. In addition, the middle-income level parents’ group (n = 295) reported higher knowledge mean score compared to the low-income parents’ group (n = 15) with a mean difference of d = 1.15, p = .041.  Conclusion: Parents’ knowledge about maintaining oral and dental health care for infants/children was inadequate. Essentially, medical professionals are the initial ones to interact with expecting and new moms. Therefore, need to raise parents’ awareness about oral and dental health for infants/children, through the development and implementation of long-term education and promotions programs.

In developing countries, malnutrition represents a public health problem, which affects many children under five, during their complementary feeding period. One way to overcome this problem is through the supplementation of complementary flours with locally available food resources, such as Moringa oleifera leaf (MOL). An experimental study was conducted from June through November 2019 in the southern-Benin, with moderately acutely malnourished (MAM) children, using a porridge made of a mixture of corn, malted sorghum, soybean, peanut, milk, and moringa leaf powder. A total of 150 MAM children aged 12-59 months were recruited and divided into two groups, an intervention group (48) and a control group (75). The intervention group received the test food, a porridge made of maize flour supplemented with Moringa oleifera leaf flour (MOL-flour), at least 5 times/week for 6 months. The control group, whose mothers received nutritional education sessions on food diversification as well as the different ways of preparing MOL meals. Sensory evaluation, anthropometric and dietary diversity data were collected. Z-scores Weight/Height, Weight/Age et Height/Age were determined before and right after the intervention. Results showed that 70% of the children and more than 75% of the mothers assessed the porridge as palatable. A significant average weight gain of 1.720 g (p < 0.005) was observed in the intervention group at the end of the experimentation, with a reduction of the prevalence of underweight by 1,33% (p > 0.05), and the number of acute Malnutrition children by 10,42% (p < 0.005).

During this period of time, mushroom experience changes in functional aspects and consumption areas. Due to its magnificent role in promoting health, it was considered one of the most healthy sources of food. Agaricus spp., Marcrolepoita spp., Auricularia spp, Armillaria spp, Pholoita, Hericium, Grifola spp, Flammulina, and Hypsizygus spp. are some most commonly consumed mushrooms in the world. They provide inexpensive means of nutritious and tasty food worldwide. However, ancient people are also very much aware of their holistic function towards health and that was why they used mushrooms for medicinal purposes in the past onwards. Mushroom plays an important role in the treatment of some lethal diseases like cancer, inflammation, autoimmune disorders, allergy, hypertension, arthritis, hyperglycemia, atherosclerosis, and many more. Meanwhile, researchers still focus on other functions of mushrooms in health science and also explore their anticancerous activity. However, many findings are left to be found in the future. This review paper throws light on the various important mushrooms and their functions related to human health, and also ongoing research towards treating some critical diseases.

The demand for pesticides has increased in today’s world of expanding population in order to boost crop productivity and eliminate undesirable plants (weeds) that grow alongside the primary crop. Along with the various benefits, it is also used in animal farms to get rid of pests. This has an impact not only on humans but also on animals and the environment. The usage of pesticides has increased, and occasionally some of them linger in the food products they are applied to, a condition known as pesticide residue. This residue is linked to human health and can result in a variety of diseases and disorders. In the current environment, even pesticides that are marketed as benign have negative long-term effects and exacerbate issues like bioaccumulation and bio-magnification. To avoid food contamination with pesticides, different methods like crop rotation, organic farming, and integrated pest management should be used as alternatives. Today, it is essential for all pesticide users to be aware of the risk and proper handling of these pesticides. New methods of pest management should be fostered in the realm of development.

Background/Aim: There has been a progressive rise in the incidence and prevalence of End Stage Renal Disease (ESRD). It has also been observed that the most important reasons for a rapid increase in Chronic Kidney Disease (CKD) patients are the rapidly increasing worldwide incidence of diabetes and hypertension. The present study evaluates the effect of diabetes, hypertension, and comorbid state of hypertension and diabetes (hypertensive-diabetic) on renal function using serum creatinine and urea as markers. Method: A total number of 120 persons were recruited for the research; 30 controls, 30 hypertensive, 30 diabetic, and 30 hypertensive-diabetic persons. Of the 30 control persons, 18 were females and 12 were males; of the 30 hypertensive subjects, 17 were females and 13 were males; of the 30 diabetics subjects, 20 were females and 10 were males, whereas of the 30 hypertensive-diabetic subjects, 21 were females and 9 were males. In total, there were seventy-six (76) females and 44 males. The respondents were pulled from Central Hospital (Auchi) Diabetic and General Clinic and Auchi Polytechnic Cottage Hospital. Verbal consent was sort and questionnaires were used to extract information regarding biodata and patients’ history of diabetes and hypertension. Height and weight were measured, and blood pressure was determined taken. Blood samples were collected into fluoride oxalate and lithium heparin bottle for the assessment of FBS and (serum urea and creatinine) respectively. Results: The mean (±SD) serum creatinine was higher in the hypertensive-diabetic group (2.08 ± 1.06) and declined as follows: diabetic group (1.75 ± 1.01), hypertensive group (1.34 ± 0.96) and control group (0.70 ± 0.14). The mean (±SD) serum urea was also found to be higher in the hypertensive-diabetic group (17.5 ± 9.06) and declined as follows: diabetic group (14.5 ± 6.13), hypertensive group (12.7 ± 6.23) and control group (7.18 ± 5.06). There was a positive correlation between serum creatinine and fasting blood sugar The study also established a positive correlation between serum creatinine and blood pressure but not between serum urea and blood pressure with r values of 0.31 and 0.16 respectively. Conclusion: Good control of blood glucose and blood pressure levels reduces the likelihood of the development of renal impairment which is usually associated with both diabetes and hypertension. Co-morbidity of diabetes and hypertension poses a higher risk of developing renal disease than individual problems of diabetes and hypertension. Serum creatinine and serum urea are important biomarkers for renal impairment hence the two should be monitored on a regular basis for diabetic and hypertensive patients and much more frequently for hypertensive-diabetic patients.

Stress, pain, injuries, and errors in dental procedures are situations highly linked to dentistry derived from multiple factors making this profession a profession with high physical and mental demand to achieve quality treatment without deteriorating the health of those who perform it, in this case, the dentist, the assistant, and hygienist.The effects of wrong postures, but above all, the lack of knowledge of the proper postures, the modeling of bad habits acquired during the training stage in dental school, and the lack of work guidelines that not only take into account the dentist but also to all the work staff and the methodological organization of dental tasks can be found in the scientific literature.Magnification devices are known to improve vision, precision, and ergonomics in dentistry; advances in the area of ​​high magnification in dentistry are taking place by leaps and bounds. In recent years, a new magnification loupes design has appeared on the market, called ergonomic magnification loupes appeared that stands out from conventional Galilean and Keplerian through the lens (TTL) Flip-up loupes in terms of their postural benefits and is part of the arsenal of magnification loupes to consider in the market.The postural approach of high magnification equipment is necessary for professional practice, where the design of Ergonomic magnification loupes with consideration not only for magnification but also for the operator’s postural health which can have a significant impact on the performance and overall health of the dentist and hygienist, more if incorporated from the beginning of dental school education and training.

Introduction: Myopia is a refractive disorder commonly diagnosed in childhood that follows a progressive course. It is considered a global epidemic with nearly 23% of the world’s population being diagnosed with this condition. Moreover, myopia is increasing in prevalence worldwide, demonstrated by studies in Asian and Western populations. This has important implications as myopic progression to high myopia is associated with significant morbidity and visual disability if left untreated. Of these treatments, the pharmacologic agent atropine has demonstrated the greatest efficacy in reducing myopia progression.Case report: This is a case report of an 11-year-old male treated with 0.01% atropine drops for myopia progression that developed new-onset seizures. The seizures were characterized as benign epilepsy with central temporal spikes and ceased when drops were discontinued. Discussion: Atropine 1% drops have previously been associated with new or increased seizure activity in a handful of case reports, however, it is our knowledge that this is the first report associated with 0.01% drops. This is important given the growing use of 0.01% drops as well as higher concentrations such as 0.025 % and 0.05% for the treatment of pediatric myopia. Conclusion: While it cannot be proven that the drops were causative in the seizure events, it is important to consider prior seizures as a relative contraindication to the use of these drops.  Atropine has the potential to exacerbate seizure activity, so it is possible that the 0.01% atropine drops played a role in the patient’s seizures. Also, any diagnosis of new-onset seizures in pediatric patients should prompt discontinuation of drops at seizure onset.

Introduction: Cardiac tamponade is an emergency syndrome that requires fast diagnosis and treatment; otherwise patient follows obstructive shock and cardiac arrest. Case report: A 70-year-old female was brought to the emergency department with hypoxemia. She had a history of progressive dyspnea over the past three weeks. Past medical history includes smoking. On physical examination: tachypnea, hypoxemia (SaO2 89%), jugular venous distention, arterial pressure 220/100 mmHg, heart rate rhythmic of 82 bpm. On pulmonary auscultation: diffuse and bilateral crackles. Lung ultrasound showed a bilateral B line and the echocardiogram demonstrated a pericardial effusion with signs of tamponade. A pericardiocentesis evacuated 620 ml of hemorrhagic fluid and the patient was transferred to the intensive care unit, hemodynamically stable, with SaO2 95%. At the ICU the echocardiogram, showed resolution of the cardiac tamponade and a tumor adhered to the lateral wall of the left ventricle. Chest CT demonstrated: a left lung tumor, infiltrating the pericardial sac. A pericardium biopsy demonstrated undifferentiated carcinoma. Discussion: Cardiac tamponade diagnosis requires a high level of suspicion. Respiratory failure, chest pain, and shock, observed in cardiac tamponade, are also present in different diseases. The most common finding of cardiac tamponade is dyspnea (78% of cases). Our patient had dyspnea due to pulmonary edema, secondary to left ventricle diastolic dysfunction caused by the tamponade. A bedside echocardiogram made the diagnosis of cardiac tamponade and guided the effective pericardiocentesis. Conclusion: Cardiac tamponade must be suspected in all cases of acute dyspnea. Echocardiogram is the method of choice for the diagnosis and for guiding the pericardiocentesis.

The global pandemic COVID-19, caused by SARS-CoV-2, affected millions of people. COVID-19 is known for its respiratory symptoms, but new research reveals it may also affect other organ systems, including the liver. This abstract reviews COVID-19 and liver function. The virus enters host cells through liver-expressed angiotensin-converting enzyme 2 (ACE2) receptors. Thus, viral infection and replication may target the liver. Virus-induced inflammation and cytokine production may also harm the liver. ALT and AST elevations are the most prevalent liver abnormalities in COVID-19 patients. Liver function test abnormalities frequently indicate serious illness and poor clinical outcomes. COVID-19 may worsen pre-existing liver diseases such as NAFLD and chronic viral hepatitis. Drug-induced liver damage (DILI) from COVID-19 therapies including antivirals and corticosteroids complicates liver complications care. Recent investigations have also shown that COVID-19 may cause long-term liver damage. In conclusion, COVID-19 infection, immune-mediated damage, and treatment problems may severely compromise liver function. Optimizing patient treatment and discovering targeted medicines requires understanding COVID-19's liver role. To reduce the effects of COVID-19 on liver function, further study is required to understand the mechanisms and long-term effects.

Photobiomodulation (PBM) is an effective method for treating neuropsychiatric diseases, yet its universal acceptance and utilization remain constrained. In this Letter to the Editor/Expert Opinion, we address the challenges confronting PBM researchers and pioneers, striving to establish universal confidence in its exclusive application for neuropsychiatric patient care. Despite encouraging animal experiments and selecting positive human clinical trial outcomes, PBM’s widespread acceptance of PBM is hindered by factors including limited clinical studies and clashes with established therapies, such as drug therapy and psychotherapy.To overcome these obstacles and broaden PBM’s adoption and application of PBM in neuropsychiatry, we propose a combinatorial therapy approach. By integrating PBM with interventions such as Cognitive Behavioral Therapy (CBT) or drug therapy, a cumulative effect can be attained, benefiting both patients and therapists. Patients gain access to diverse treatment options and experience synergistic effects of combined therapies, thereby enhancing outcomes. Therapists benefit from expanded intervention choices and improved quality of patient care.This study introduces a novel strategy of amalgamating PBM with recognized interventions, such as CBT and drug therapy, to address existing challenges. This combined approach offers a practical solution to augment PBM acceptance and usage in the realm of neuropsychiatry.To endorse this strategy, a shift in the research direction is imperative. Future studies should investigate the amalgamated use of PBM with other neurointerventions, such as CBT or drug therapy. Robust clinical trials contrasting groups like “PBM + CBT” and “PBM (sham) + rTMS” are vital to persuade clinicians and patients toward embracing combined PBM therapies.Although PBM’s eventual autonomy as a neuropsychiatric treatment is an overarching goal, the present combination therapy approach proves practical, inevitable, and mutually beneficial. By bridging conventional therapies with PBM, this strategy may facilitate wider acceptance and utilization in neuropsychiatry.

The newly launched IAEA project MEREIA (MEthods for Radiological and Environmental Impact Assessment; 2021- 2025), MEREIA continues some activities of previous IAEA exercises in the field of radioecological modelling and focuses on areas where the probabilistic approach determines the predictive capability of environmental models. The program offered the opportunity to set up well-designed and verified scenarios to collect and compare exposures predicted by particular models based on this scenario and then perform a validation study of contributing models. It consists of the comparison of model prediction with observed data or in the case where there is a lack of measurement data to perform a comparison within model prognoses.  The previous international works have brought significant improvement in environmental modeling in terms of better understanding and mathematical description of complex physical and chemical phenomena that occur in various environmental media and also have promoted new areas for experimental investigations. The new experimental results yielded updated handbooks of a large number of environmental parameters for less-known elements. Moreover, the principal objective of the activities in environmental modelling was an integrated risk assessment of the reference group of population and biota associated with radionuclides releases from various kinds of nuclear facilities as from different types and power nuclear reactors, radioactive waste disposal and more complex nuclear research facility. This reflects recent international recommendations to extend protection against radiation hazards of humans to wildlife flora and fauna. However, the statistics supported knowledge on some essential environmental parameters still remain small. Therefore, one could be aware of some limitations of the probabilistic approach that required advanced methods of probabilistic prognosis Monte Carlo.

A new technique for the use of Artificial Neural Networks (ANN) for the generalization and visual presentation of the results of experimental studies is proposed. The possibility of using ANN for cases for which their use was previously considered impossible is shown. ANN calculators have been created that summarize the results of experimental studies on the effect of trans-polynorbornene and basalt fiber on the characteristics of a rubber compound based on general-purpose rubbers (isoprene SKI-3, butadiene-methylstyrene SKMS-30ARK and butadiene SKD), which also contained vulcanizing agents (N, N′-dithiodimorpholine, thiuram D), vulcanization accelerators (sulfenamide C, 2-mercapto-benzothiazole), vulcanization activators (zinc white, stearic acid), emollients (industrial oil I-12A, rosin) and antioxidants (acetonanil H, diaphene FP). The rubber mixture was prepared on laboratory rollers LB 320 160/160. Subsequently, the rubber mixture was vulcanized in a P-V-100-3RT-2-PCD press. For the resulting vulcanizates, the physical and mechanical properties and their changes were determined after daily exposure to air and in a standard SZhR-1 hydrocarbon liquid at a temperature of 100 °C. We also studied the change in the mass of vulcanizates after exposure to industrial oil I-20A and water. The dynamic parameters (modulus of elasticity and mechanical loss tangent) of vulcanizates, which characterize their noise and vibration-absorbing properties, were studied on a Metravib VHF 104 dynamic mechanical analyzer. The created ANN calculators allow solving a direct problem - interpolating the dependences of all rubber characteristics on the content of basalt fiber, as well as solving inverse problems - to determine the required content of basalt fiber to create rubber with the required performance properties. The autonomous executable modules of the calculators developed by ANN were made and can be passed to everyone.

Rising greenhouse gas emissions have contributed to unprecedented levels of climate change, while microbial conversion and utilization of CO2 is a practical way to reduce emissions and promote green manufacturing. This article mainly summarizes several natural CO2 pathways that have been discovered, including the Calvin cycle, the reduced tricarboxylic acid (rTCA) cycle, the Wood–Ljungdahl (WL) pathway, the 3-hydroxypropionate/4-hydroxybutyrate (HP/HB) cycle, the dicarboxylate/4-hydroxybutyrate (DC/HB) cycle, the 3-hydroxypropionate (3HP) cycle, the reductive glycine (rGly) pathway, and artificially designed carbon fixation pathways includes the CETCH cycle, the MOG pathway, the acetyl-CoA bicycle, and the POAP cycle. We also discussed applications of different carbon fixation enzymes, notably ribulose-1, 5-diphosphate carboxylase/oxygenase, pyruvate carboxylase, carbonic anhydrase, as well as formate dehydrogenase. This paper further addressed the development of photosynthetic autotrophs, chemergic autotrophs and model bacteria Escherichia coli or yeast produced main products for CO2 fixation through metabolic engineering, such as alcohols, organic acids, fatty acids and lipids, bioplastics, terpenoids, hydrocarbons, and biomass.  Future studies on CO2 microbial conversion should focus on improving the efficiency of carbon fixation enzymes, metabolic modules of the carbon sequestration pathway, and intracellular energy utilization. Coupled microbial and electrochemical methods for CO2 fixation, in addition to biological fixation, show considerable promise.
