Plasma stability is the biggest challenge facing the nuclear fusion industry. One of the best methods of stability study is magnetohydrodynamic (MHD) equations, which has two linear and nonlinear states. Usually linear stability analysis is used to describe the MHD state, which is obtained by linearizing nonlinear equations. The reactor under study is the W7-X reactor, which is an optimal example of a stellaratoric system. The question raised in this research is how to create suitable conditions for the formation of plasma and heat transfer produced by the melting reaction. Many efforts have been made in this direction, but still the record holder for plasma state maintenance belongs to the international ITER project and around 1000. However, IPP researchers at the Max Planck Institute in Germany (maker of the W7-X reactor) predicted that by 2020 they would produce a pulse of 30 minutes. The numerical method is used to investigate the stability of the reactor. In this paper, boundary conditions were expressed in terms of resistance wall. With the help of the mathematical Matlab software, magnetic field values ​​were obtained from experimental reports extracted from the Max Planck Institute for various values ​​of β. From the values ​​obtained, it was concluded that the appropriate field value is β = 5 according to the ideal MagnetoHydroDynamic state and the interval defined by the Max Planck Institute.

Resource recovery provides an opportunity to transform limited and abundant materials in form of waste into biobased products. In the production system, this technique could offer an economic means to utilize wastes to generate valuable products which are fundamental to a sustainable economy.

Fibrothecal tumors of the ovary are rare neoplasms, comprising less than 4% of all ovarian tumors and primarily affecting post-menopausal women. These benign tumors arise from the stromal tissue of the ovary and may produce hormones, particularly estrogen. Their diagnosis presents considerable challenges, frequently leading to misclassification as malignant ovarian tumors or uterine myomas. This report describes the case of a 59-year-old woman who presented with abdominal distension and pelvic pain. Clinical examination revealed a large, lobulated mass and imaging studies classified the right ovarian mass as ORADS 4. An exploratory laparotomy confirmed the absence of metastasis, resulting in total hysterectomy, bilateral adnexectomy, and omentectomy. The anatomopathological analysis identified the latero-ovarian mass as a fibrothecoma. Generally, fibrothecal tumors are benign with a favorable prognosis following surgical intervention. Common symptoms include pelvic pain and abdominal distension, and diagnosis typically relies on imaging techniques such as ultrasound and CT, with definitive confirmation achieved through histopathological examination. Given their potential to mimic malignant ovarian cancer, accurate diagnosis is critical and necessitates a multidisciplinary approach.

A 34-week premature newborn, child of a mother without prenatal controls, a marijuana user, with gestational syphilis with a positive rapid plasma reagin test (RPR) titer 1:16, did not receive treatment during pregnancy. The newborn presented congenital syphilis, RPR titer 1: 256 positive test.

The main purpose of this report was to develop application of poly-dopamine-beta-cyclodextrin modified glassy carbon electrode (PDA-β-CD-GCE) towards electrooxidation and determination of L-Tryptophan (L-Trp) and also the evaluation its kinetic parameters. In continuation of our efforts to use PDA-β-CD-GCE for amino acids detection, our objective in the present work was to expand application of this sensor for the determination of L-Trp which is very sensitive.

Background: Microorganisms belonging to Streptomyces sp. are Gram-positive bacteria known for their unsurpassed capacity for the production of secondary metabolites with diverse biological activities. The aim of this study was to evaluate the antimicrobial and antioxidant properties of ethyl acetate Streptomyces sp. PERM2 extract, its potential modes of action and bioactive secondary metabolites.Results: The ethyl acetate PERM2 extract showed antimicrobial activity more pronounced on both Gram-positive and Gram-negative bacteria and fungi with a Minimum Inhibitory Concentration value (MIC) of 0.5 mg/mL and Minimum Bactericidal Concentration (MBC) of 2 - 4 mg/mL against bacterial pathogens. MIC value against pathogenic fungi was 2 mg/mL and Minimum Fungicidal Concentration (MFC) of 0.01 - 0.05 mg/mL against pathogenic fungi. PERM2 crude extract showed the ability to inhibit bacteria cell wall synthesis at 0.5 and 1 MIC. The extract was found to possess dose-dependent 2,2-Diphenyl-picrylhadrazyl (DPPH) free radical scavenging and Ferric reducing activity. The gas chromatography-mass spectrometry (GC-MS) analysis revealed the presence of three major compounds identified as 9,12-octadecadienoic acid (Z, Z) (29.75%), tridecyl trifluoroacetate (24.82%) and 1-(+)-ascorbic acid 2, 6-dihexadecanoate (22.34%). The liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis revealed the presence of 22 non-volatile metabolites in PERM2 extract and only the compound 3, 30-O-dimethylellagic acid was identified. Conclusion: The results of this study indicate that ethyl acetate Streptomyces sp. PERM2 extract possesses antibacterial, antifungal, and antioxidant activities; inhibits bacteria cell wall and protein synthesis; and contains significant bioactive secondary metabolites which could be used as an alternative to multi-resistance antibiotics.

Congenital Dyserythropoietic Anaemia (CDA) is a rare genetic disorder that affects the maturation of red blood cells. The disorder is classified into different types, with a prevalence ranging from 1 in 100,000 to 1 in 1,000,000 individuals. Treatment strategies are designed with the primary focus on symptom management, the prevention and treatment of complications, and the underlying disease pathophysiology. The advent of bone marrow transplantation, gene therapy, and targeted therapies has considerably expanded the scope for therapeutic intervention in CDAs. Supportive care, including blood transfusions and iron chelation therapy, has demonstrated efficacy in managing iron overload and improving overall survival rates. The potential of gene therapy, targeted therapies, and hematopoietic growth factors in the treatment of CDA is currently being investigated. Further research and clinical trials are required to develop more effective and personalized therapeutic interventions.

An increased scientific interest is observed nowadays in the clinical application of Equine Assisted therapy for patients with mental disorders, reflected on recent numerous systematic reviews, scoping reviews and concept analyses.

The present study aimed to analyze Cholinesterase (CE) levels in cord blood from preeclamptic women and to evaluate cholinesterase status in patients with osteosarcoma. Serum cholinesterase levels were assessed in 30 cases of osteosarcoma and 30 controls suffering from musculoskeletal pain. Additionally, maternal and cord blood samples were collected from 25 women with preeclampsia and compared with those from 25 normotensive pregnant women and 25 normal, healthy controls. The results indicated that serum cholinesterase levels were significantly lower in osteosarcoma patients (Group I) compared to those with musculoskeletal pain (Group II, p < 0.05). Similarly, cholinesterase levels were reduced in the maternal blood of women with preeclampsia when compared to normotensive controls. Cord blood cholinesterase levels were lower in the infants of normotensive mothers, with levels reaching 88.65% of the maternal levels. Furthermore, cord blood cholinesterase levels were significantly lower in preeclamptic women compared to normotensive pregnant women. When comparing cholinesterase levels to those of normal controls, it was observed that CE levels were significantly elevated in both normotensive and preeclamptic women. The findings of low serum cholinesterase levels in this study suggest that cholinesterase secreted by osteoblasts is utilized in bone formation and tumorigenesis. Additionally, the decrease in cholinesterase levels associated with preeclampsia may be linked to the loss of muscarinic cholinergic receptors that occur in this condition.

Congenital fibrinogen qualitative disorders, including dysfibrinogenemia and hypo-dysfibrinogenaemia, are highly heterogeneous, both in clinical manifestation and for the mutational molecular spectrum driving these disorders. Correlations between phenotype and genotype remain poorly defined. Considerable work lies ahead in order to achieve diagnostic and prognostic precision and subsequently provide targeted management for this rare disease. Here we report the laboratory test, the clinical and molecular characterisation of a family with dysfibrinogenemia.
