Background: Angiotensin-converting enzyme 2 (ACE2) is a receptor for SARS-CoV-2, expressed in many organs’ cells, including the thyroid gland. Therefore, COVID-19 may influence thyroid gland function. Objectives: In this article, we aimed to investigate the thyroid gland function in COVID-19 patients and compare them to healthy society to indicate whether thyroid hormones level differ in the disease or not. Methods: This is a single-center retrospective case-control, cross-sectional study on 191 COVID-19 patients and 179 non-COVID-19 individuals as the control group. The status of the thyroid hormones was determined in COVID-19 patients and then compared with the control group. Patients in the case group were divided into 2 groups with and without normal thyroid function and were compared with each other in different aspects of COVID-19. Also, we compared thyroid hormone levels in the patient group with different underlying diseases to show the status of thyroid function in COVID-19 infection. Results: Of the 191 COVID-19 patients, 98 (51.3%) were male, and the mean age of patients was 64 ± 15 years. The thyrotropin level was lower in the patient group than in the control group (1.34 ± 1.29 vs. 2.21 ± 1.99; P < 0.001). The T3 status was meaningfully associated with the level of SpO2 (P < 0.05; r = -0.258). The results demonstrated that thyrotropin (P = 0.653), T3 (P = 0.404), and T4 (P = 0.147) levels were not different in expired and discharged patients. The 2 groups of patients with and without normal thyrotropin levels did not appear significantly different in any aspect of the disease. Conclusions: Thyrotropin level was lower in COVID-19 patients, and the T3 level can predict the SpO2 level. The thyroid gland may be theoretically affected by SARS-CoV-2 infection.

Beta-glucosidase enzyme belongs to family GH3 is widely used in food, medicine and pharmaceutical industries. In order to quickly search for these enzyme coding sequences from DNA metagenomic data, in this study, bacterial-derived enzyme-coding sequences which was investigated empirically on the CAZy database was collected. By analogy, we have developed that a specific probe for beta-glucosidase GH3 had a length of 330 amino acids, which contains 26 conserved residues in all sequences, 37 residues similar in almost sequences, and 21 residues conserved in many sequences and homologous with all the reference sequences with the lowest coverage and identity of 79% and 38% respectively and max score of 122. Probe was used and extracted 59 coded sequences of beta-glucosidase GH3 from the metagenome DNA sequences of goat rumen bacteria. The most ORFs were annotated as beta-glucosidase GH3 by KEGG and CAZy. The sequences are estimated to have a tertiary structure similar to beta-glucosidase.

The article studies the characteristics of tolerance to the occupational factors of flying labor in military pilots (MP) of the Socialist Republic of Vietnam with the aim of fulfill the psychophysiological training system for military pilots. The study involved 17 Vietnamese and 24 Russian MP between the ages of 19 and 22. Conducted an endurance assessment against flight factors such as overload, hypoxia and effects of balance dynamics on the basis of using statoergometric, hypoxia test and vestibular organ test “OR-10”. Before and after being subjected to the above effects, MP were evaluated for psychophysiological characteristics by measuring critical flicker fusion frequency (CFFF) and reaction time test (RTT) and physiological indicators about computer balance ability during hypoxia. In addition, height and weight indexes were also included in the study. The results showed that there was a significant difference between the two study groups with the difference in height, weight, BMI and flying overload capacity in the Russian MP group were higher. At the same time, there was also a difference in psychophysiological indicators between the two groups. Assessment of hypoxia tolerance and cochlear vestibular testing (OR-10) based on computerized balance indices showed different predispositions for each group. This is because in the Vietnamese MP group, there has appeared an adaptive mechanism in a state of greater exertion than in the Russian group. The results of the study show that it is necessary to improve the psychophysiological training system for Vietnamese pilots in order to improve their ability to resist the effects of occupational factors during flight operations highly maneuverable aircraft manufactured by the Russian Federation.

The monitoring and treatment of patients after kidney transplant is important in maintaining transplant kidney function, including BK polyomavirus surveillance. BKV is a common opportunistic pathogen in kidney transplant patients and can cause BKV-associated nephropathy, which represents a major problem for these patients, causing graft dysfunction and graft loss. BKV is classified into four genotypes, I, II, III and IV. Here, thirty urine samples from kidney transplant patients were collected and quantified BKV-DNA loads by real-time PCR, viral loads were 105-1010 copies/ml. We successfully amplified and purified the specific VP1-BKV region with 580 bp in length using primers BK_(S+AS). Additionally, we also identified BKV genotypes by PCR-RFLP using the restriction enzymes RsaI and AluI. In total 20 out of 30 cases (66.7%) were genotype I and 10 cases (33.3%) were genotype IV in collected urine samples. Comparing the obtained PCR-RFLP results with direct sequencing analysis achieved complete concordance (30/30, 100%). We successfully developed a cost-effective and accurate BKV genotyping assay using PCR-RFLP, that contributes to the monitoring of patients after kidney transplantation.

In recent years, the burden of nontuberculous mycobacteria pulmonary disease has increased worldwide. Nontuberculous mycobacteria - NTM infection is often misdiagnosed with Mycobacterium tuberculosis - MTB because of their similar clinical manifestations and preclinical manifestations. For MTB, the National Tuberculosis Program and the Ministry of Health (Vietnam) have a standard treatment regimen, while for NTM, an individualized treatment regimen based on infectious NTM species. Therefore, accurate identification of the causative NTM species can help clinicians choosing an effective treatment regimen. Among 122 suspected NTM samples collected at National Hospital 74, we successfully identified 115 strains belonging to NTM. Analytical DNA sequences, building phylogenetic trees were analyzed by Bioedit, ClustalX2, and MEGA-X software; comparing and identifying reference species from gene bank were used BLAST-NCBI. Slow-growing mycobacteria accounted for 61.7%, consists of Mycobacterium avium complex (37.4%), Mycobacterium lentiflavum (7.0%), Mycobacterium simiae (7.0%), Mycobacterium gordonae complex (5.2%) and other species less than 2.0%. The detection rate of rapid-growing mycobacteria was 38.3% including Mycobacterium abscessus complex (31.3%), and Mycobacterium fortuitum (7.0%). The most prevalent NTM species belonged to Mycobacterium avium complex and Mycobacterium abscessus complex (68.7%). The proportion of NTM infection in patients 50 years and older is 2.3 times higher than in patients under 50 years. This proportion is 5 times higher in females while there is no significant difference in males.

Published: May 2023

In the early stages of vertebral metastasis, it is hard to diagnose by plain radiograms and computed tomography. Whole body scintigraphy is sensitive to diagnose these lesions but it can not differentiate metastasis from inflamatory, traumatic and degenerative diseases. Recently, Magnetic Resonance Imaging is the most important imaging technique in the diagnosis of vertebral metastasis. Magnetic Resonance Imaging can easily demonstrate the meduller attack in vertebral bony structures and it can show the metastatic infiltrations in epidural spaces and paraspinal soft tissues.

There were 13 cases of metastasis, 9 tuberculous osteomyelitis, 3 pyogenic osteomyelitis and 4 multipl myeloma. Reliable criterias for tumoral processes were presence of posterior element involvement and paravertebral soft tissue component when paravertebral fat tissue density was normal. in infectious processes (both pyogenic and non-pyogenic) litic-destructive lesions were observed. Paravertebral soft tissue component was biJateral and large and typically paravertebral fat tissue was obliterated. There was no CT criteria observed in differentiation of pyogenic versus non-pyogenic infections. Sclerotic vertebteral lesions were characteristic for tumoral processes (especially metastasis ). If typical litic-destructive pattern is observed corpus and/or posterior elements of vertebra spesific diagnosis of multipl myeloma can be made.

من المعلوم أنّ الله سبحانه وتعالى قد يسّر حفظ كتابه فأنزله على غير حرف؛ تيسيرًا لتلاوته؛ وإكثارًا لمعانيه. ولهذا تعددت قراءاته ورواياته، وحظي بعضها بشهرة وانتشار لم يحظ بها البعض الآخر لأسباب مختلفة. والروايات القرآنية المتداولة في عصرنا الحاضر هي: روايتي ورش وقالون عن نافع المدني، ورواية حفص عن عاصم الكوفي، ورواية الدوري عن أبي عمرو البصري. ونعني بالروايات القرآنية المتداولة، أيْ الروايات القرآنية التي لها جمهور يقرأ بها في المحافل ومؤسّسات التعليم المختلفة، كما أنّ هذه الروايات القرآنية الأربعة تتفاوت فيما بينها من حيث الذيوع والانتشار، علماً بأن القراءات والروايات القرآنية المتواترة كلها وحي من الله ولا تفاضل بينها من حيث الصحة، وتوافر شروط القبول فيها. ويأتي هذا المقال للوقوف على هذه الروايات القرآنية الأربعة، من أجل التعريف بها، وبيان مواطن انتشارها وأسباب ذلك، كما يناقش مستقبل الروايات القرآنية الأخرى التي لم تجد حظها من الشهرة في هذا العصر. وقد سلك الباحث المنهج الوصفي والاستقرائي للوقوف على الرقعة الجغرافية للروايات القرآنية المتداولة في عصرنا الحاضر. وقد توصل إلى أن قارة إفريقيا هي القارة الوحيدة التي يقرأ أهلها بالروايات القرآنية الأربعة المتداولة، بينما تقرأ بقية قارات العالم برواية حفص عن عاصم الكوفي، والتي تعد أشهر رواية قرآنية في عصرنا الحاضر.

"The article focuses on Voltaire’s Le tocsin des rois, composed at Catherine the Great’s request, during the Russian-Turkish War, at the end of 1771. In 1772–1774, the text was translated into Romanian by Toma Dimitriu, a Greek from Kastoria who had established in Moldova in 1758 and who authored numerous translations, mostly from Greek, but also from French. Dimitriu’s still unedited rendition of Le tocsin des rois is one of the oldest translations from French into Romanian. This research presents the morpho-syntactic and lexical features of the text, discusses the methodological difficulties raised by Dimitriu’s translation techniques, and sheds light onto an unknown part of the history of the influence of the French literature onto the Romanian one."
Analysis of the disturbance effect in intracellular calcium dynamic on fibroblast cells with an exponential kernel law
Authors: Joshi Hardik , Yavuz Mehmet , Stamova Ivanka
Published: May 2023

The maintenance of free calcium in the cytoplasm is requisite for cell integrity and the regime of the multi-cellular process. Overproduction and degradation to manage this cellular entity produce offensive changes in tissue performance and as a result, commence fibrotic diseases. Thus, there is a necessity to know the cellular process for the inclusion and extrusion of free calcium. Here, a mathematical model is framed to investigate the role of buffer and calcium concentration on fibroblast cells. In this context, the Caputo-Fabrizio advection reaction-diffusion model along with apposite biophysical initial and boundary conditions is considered. The analytical solution is obtained and used to analyze the diverse mechanisms of calcium on fibroblast cells. The obtained results reveal that when the fractional order goes to one, the Caputo–Fabrizio fractional derivative provides a concise calcium profile and well-managed cellular entity due to the exponential kernel law.

Authors: Peng Yin , Wang Chengjun , Wu Lin
Published: May 2023

Background: The purpose of this study is to investigate the genotype and allele distribution of MTHFR rs1801133 in the Chinese population, and to analyze the relationship between gene polymorphism of MTHFR rs1801133 and risk of childhood leukemia. Methods: Blood samples and clinical data of childhood leukemia cases (n=1132) and age-matched healthy controls (n=1053) were collected. Genotypes and allele distribution of MTHFR rs1801133 were detected by PCR-RFLP. Logistic regression model was generated to analyze the relation between MTHFR rs1801133 and susceptibility to childhood leukemia and the chemotherapy response. Results: Age, sex, BMI and family history of tumor were comparable between childhood leukemia cases and healthy controls. Genotypes and allele distribution of MTHFR rs1801133 were remarkably correlated to the risk of childhood leukemia. Genotype risk of MTHFR rs1801133 was parallel to the susceptibility to childhood leukemia. Specifically, compared with people carrying AA allele of MTHFR rs1801133, higher risk of childhood leukemia may occur in people carrying AG+GG allele of MTHFR rs1801133 with a younger age (<15 years) or complete remission from chemotherapy. Conclusions: MTHFR rs1801133 gene polymorphism has a significant correlation with childhood leukemia. It is an important genetic susceptibility gene of childhood leukemia. The reliability of the results requires to be further validated by the high-quality research involving a large sample size in multi-center hospitals.
