The metabiotics of probiotic lactic acid bacteria inhibited the growth of pathogenic, conditionally pathogenic bacteria, different etiology antibiotic resistant bacteria such as Salmonella sp., E. coli, Proteus mirabilis Pasteurella spp., Clostridium sp., Streptococcus sp., Staphylococcus aureus, Shigella sp., Yersinia enterocolitica, Bacillus cereus with different efficiency depending on pathogens isolation sources. It was shown that bacteriocins of lactic acid bacteria in the same concentration did not affect growth of the commensal microbiota strains, belonging to different genera and species. Lactobacillus and Enterococcus genera showed high sensitivity to investigated antibiotics (about 70%). Among all studied LAB strains of Enterococcus genus, some strains were shown to synthesize polysaccharides. The antimicrobial activity of isolated polysaccharides from Enterococcus faecium К Э-14, Enterococcus faecium К Э-5, Enterococcus lactic acid bacteria. Sp. К Э-9, Enterococcus lactic acid bacteria sp. К Э-6 strains was investigated. It was found that only polysaccharides isolated from Enterococcus faecium К Э-14 and Enterococcus faecium К Э-5 strains show an antimicrobial effect. The Enterococcus faecium КЭ-5 (MDC 9662) lactic acid bacteria strain was selected which produce protein-like substances and disaccharide polymers with antimicrobial activity, consist of glucose and galactose. The growth suppression of different Kl. pneumonia and St. pneumonia strains causing pneumonia by antimicrobial preparations of lactic acid bacteria was shown. The highest antimicrobial activity (100%) was observed when the antimicrobial preparations obtained after cultivation of lactic acid bacteria strains of the Enterococcus genus. The activity depends on the source of isolation of pathogens from a patient. The selected strains can be recommended for the creation of probiotic preparations with targeted purposes.","PeriodicalId":353660,"journal":{"name":"THE NEW ARMENIAN MEDICAL JOURNAL","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139361271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both Pittsburgh sleep quality index and Edinburgh postnatal depression scale were used to assess the sleep quality and postpartum depression, respectively. Descriptive statistics and Chi-Square analysis was performed to examine the association between postpartum depression and sleep quality. The study results showed that there was significant association between postpartum depression and subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbance, use of sleep medications and daytime dysfunction (p<0.05). Furthermore, the study revealed that maternal complications during pregnancy and/or delivery, the chosen mode of feeding, usage of painkillers, and post-delivery complications for the child (such as hypoxia) were factors influencing the postpartum depression among the surveyed women. The study concluded that women having postpartum depression are experiencing poor sleep quality. As a result, the study recommends increasing the awareness and knowledge of Saudi women concerning postpartum depression, alongside providing them with specific coping strategies to proficiently manage and alleviate the consequences of postpartum depression.","PeriodicalId":353660,"journal":{"name":"THE NEW ARMENIAN MEDICAL JOURNAL","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139370853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Testing was carried out on white mongrel mice and reliably shown that the introduction of a hydroxypropyl residue into the composition of the synthesized hydrazides leads to new properties, namely hypotensive activity, not previously observed in compounds class of carboxylic acid hydrazides of various structures. The most active compounds have been selected and tested in rats and cats. It has been established that the lethal dose (lethal doses 50) of the proposed compounds ranges from 550-762 mg/kg and they exhibit superior activity compared to those used in the medical preparation “Dibazol”. In order to find new useful properties in a series of gamma-hydroxy acid hydrazides, their antioxidant features were studied by the method of competitive reactions. As a competitive acceptor, 4-nitroso-N,N-dimethylaniline was used. According to the rate of discoloration of the last the reactivity of H radicals with respect to the studied compounds was determined. H radicals were initiated by photolysis of hydrogen peroxide (conc, 10-3 mol/l), under exposure to ultraviolet radiation, at a wavelength of 313 nm. Initiation rate H radicals were measured by the rate of change in the optical density of para-Nitroso-N,Ndimethyl aniline in distilled water and in the presence of the studied compounds.

Ginger is obtained from a yellow plant with purple veins with the scientific name Zingiber officinale. Although ginger is usually referred to as the root of the plant, actually the part used is the swollen underground stem called the rhizome. The aroma and flavor of ginger are due to the presence of two types of volatile oils and non-volatile pungent compounds. The biologically active components of ginger are classified in the second category, among the most important molecules in this category, are gingerol and shogaol, which cause a pungent sensation in the mouth. Most properties of ginger are attributed to non-volatile components with a spicy taste. The properties of these substances can be reduced blood sugar, weight loss, increased blood insulin, effect on blood coagulation, effect on blood pressure, reduction of complications of gastrointestinal diseases, reduction of nausea caused by pregnancy, or the use of chemotherapy drugs, the protective effect of the tissue against chemical and radio damage with anti-inflammatory properties, antioxidant properties, antibacterial and antifungal properties, especially Candida albicans, anti-cancer properties through antioxidant and anti-inflammatory properties.

Given the increasing impact of breast cancer in developing countries, early detection and timely treatment are crucial in reducing morbidity and mortality associated with the disease. Mammography screening is a well-established method for early detection, as it can identify breast cancer at an early stage when the chances of successful treatment are higher. Mobile mammography screening has the potential to significantly improve early detection and reduce mortality rates associated with breast cancer in developing countries. However, various challenges still impede the full realization of its benefits. This review article aims to identify and explore the challenges and prospects of implementing mobile mammography screening programs in developing countries, and to provide recommendations on how to overcome these obstacles. Overall, the future of mobile mammography screening in developing countries can be promising, with opportunities for technological advancements, increased global cooperation, and ongoing research to further enhance the effectiveness of these programs. By seizing these opportunities and addressing the challenges related to accessibility, affordability, human resources, cultural and social factors, and infrastructure, mobile mammography screening can make a significant impact on the lives of women in developing countries and contribute to reducing global disparities in breast cancer care. Several successful mobile mammography screening projects in low- and middle-income countries showcase the potential for such programs to improve access to early detection services, raise breast cancer awareness, and ultimately reduce breast cancer mortality rates. By adapting best practices and lessons learned from these projects, other low- and middle-income countries can develop and implement mobile mammography screening programs tailored to their unique contexts and resource constraints.","PeriodicalId":353660,"journal":{"name":"THE NEW ARMENIAN MEDICAL JOURNAL","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139370808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, patients under the age of 45 were selected (n=351). Patients who experienced post-myocardial infarction were identified using data from clinical and anamnestic records, in accordance with the International Classification of Diseases, 10th Revision - their proportion was 0.85% (n=3) (all male patients; mean age 35 ± 1.4 years). Two out of three were smokers and had other traditional risk factors such as hypertension, dyslipidemia and overweight. In addition, patients had important comorbid diseases: morbid obesity, lymphogranulomatosis, hepatitis with transformation to liver cirrhosis. All of them had confirmed atherosclerosis of the arteries of the lower extremities. Probably one of the main precipitating factors for myocardial infarction development in them was a hereditary predisposition due to a burdened family history, although none of them met the Dutch Lipid Clinics Network criteria for familial hyperlipidemia and none of them underwent genetic testing. A better understanding of risk factors and pathophysiological pathways in young adults may improve strategies for both preventing and treating myocardial infarction in this patient group. Raising awareness can help identify young individuals at higher risk and determine primary prevention strategies. However, the identification of patients with premature coronary artery disease by screening for traditional risk factors does not effectively identify patients at risk prior to the diagnosis of myocardial infarction. Additional studies are needed to evaluate new risk factors and apply additional imaging techniques so that these patients can be identified before myocardial infarction occurs.","PeriodicalId":353660,"journal":{"name":"THE NEW ARMENIAN MEDICAL JOURNAL","volume":"518 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135837781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In October 2015, a 14-year-old female presented with cachexia, dysphagia, diplopia, discoordination, strabismus, and multiple cranial nerve palsies. An MRI examination revealed an intra-extracranial mass arising from C2 vertebrae, compressing the medulla oblongata and the left cerebellar hemisphere, invading the sphenoid bone and nasopharynges. The biopsy results revealed the presence of a giant cell tumor of bone. The first surgical resection was incomplete because of tumor location (cranial nerve and vertebral artery involvement). The patient received local radiotherapy with 50.4Gy, but the patient’s condition worsened during this period and subsequent MRI examination showed disease progression. In March 2016, the administration of denosumab at a dosage of 120 mg every 4 weeks was initiated, and induced rapid clinical improvement and radiographically proven partial response. Disease was under control for three years until March 2019, when she returned with clinical symptoms of diplopia and severe headache. MRI showed local tumor progression. Repeated biopsy revealed an undifferentiated pleomorphic sarcoma. Two cycles of chemotherapy with Ifosfamide/Doxorubicin were administered, but MRI after chemotherapy showed marked tumor progression.
