Photodynamic therapy (PDT) is increasingly used in modern medicine. Currently, PDT is an innovative method of treating breast cancer. Irreversible damage to neoplastic tissues is associated with the use of physicochemical processes. Generating cytotoxic reactive oxygen species [singlet oxygen (1O2)] is leading to tumor cell death. At the same time, valuable information can be extracted from breast cancer cells. Photogenerated 1O2 is the major factor responsible for cell necrosis during PDT. 1O2 can react rapidly intracellularly with all organic substances. The use of photodynamic therapy on tissues in vitro creates conditions for testing various types of solutions and implementing them in in vivo treatment. This article is a review of recent advances in PDT for treatment of breast cancer. PDT is a novel cancer diagnostic and cancer treatment therapy. Therefore, an understanding of the possibility to generate a toxic form of 1O2 is necessary. The knowledge gained from the basics of PDT in vitro can be useful in biomedical applications in vivo. The current literature mentions PDT in the treatment of cancers located very deep within the human body. Therefore, the development of agents used to deliver 1O2 to the deep cancerous tissue is a new challenge which can have an efficient impact on this discipline.

Genetic studies estimated 30% heritability in BC risk. Adiponectin is an adipocytokine that has important roles in the regulation of energy metabolism. Recent evidence suggests dysregulation of adiponectin levels in BC tissues. Serum level of adiponectin is influenced by single nucleotide polymorphisms (SNPs) in the ADIPOQ gene. However, limited evidence is available regarding the association between adiponectin serum levels or SNPs in ADIPOQ and BC risk. This study aimed to assess whether adiponectin serum levels or SNPs in ADIPOQ may modify BC risk. In this case-control study, 114 BC patients were recruited along with 114 controls. Study subjects were genotyped for variations in ADIPOQ SNPs, namely rs17300539, rs266729, rs2241766, and rs1501299. Adiponectin levels were measured from the serum of study subjects. Our analysis showed that the G allele and the GG genotype of rs1501299 were significantly more frequent in BC patients compared to those in the control group (p-value < 0.05). Moreover, two ADIPOQ haplotypes containing the above G allele were associated with increased BC risk (p-value < 0.05). Multivariate analysis showed that increased serum adiponectin, smoking or age were all significant predictors of BC (p-value < 0.05). The data supports use of serum adiponectin and the G allele of rs1501299 SNP in ADIPOQ as potential biomarkers and/or targets in BC.

The computer-aided prognosis of atherosclerotic events with the electrocardiogram (ECG) derived heart rate variability (HRV) can be a robust method in the prognosis of atherosclerosis events. METHODS A total of 70 male subjects aged 55 ± 5 years participated in the study. The lead-II ECG was recorded and sampled at 200 Hz. The tachogram was obtained from the ECG signal and used to extract twenty-five HRV features. The one-way Analysis of variance (ANOVA) test was performed to find the significant differences between the CAD, MI, and control subjects. Features were used in the training and testing of a two-class artificial neural network (ANN) and support vector machine (SVM). RESULTS The obtained results revealed depressed HRV under atherosclerosis. Accuracy of 100% was obtained in classifying CAD and MI subjects from the controls using ANN. Accuracy was 99.6% with SVM, and in the classification of CAD from MI subjects using SVM and ANN, 99.3% and 99.0% accuracy was obtained respectively. CONCLUSIONS Depressed HRV has been suggested to be a marker in the identification of atherosclerotic events. The good accuracy observed in classification between control, CAD, and MI subjects, revealed it to be a non-invasive cost-effective approach in the prognosis of atherosclerotic events.","PeriodicalId":14912,"journal":{"name":"Journal of applied biomedicine","volume":"20 2","pages":"70-79"},"PeriodicalIF":1.3,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40122129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The emergence of MDR super bacteria such as Pseudomonas aeruginosa, Staphylococcus aureus, Enterococcus spp, fungi such as Aspergillus niger and Candida spp, has been identified to significantly increase the incidence rate. Therefore, it is necessary to develop a suitable barrier to prevent infection and enhance wound healing. On the other hand, medicinal plants could represent a significant source of new antimicrobial drugs for combating MDR pathogens. Out of 60 clinical skin burn cases, 51 patients (85%) had polymicrobial infections, while the remaining had monomicrobial infections. Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, and Klebsiella pneumonia were identified as the most common bacterial isolates based on morphological and biochemical tests. However, Candida albicans, Candida parasitosis, Candida glabrata, Candida famata, Aspergillus niger, and Exophilia spinifera were the most common fungal isolates found in skin burn cases. MDR classification was reported in 21 of the 39 bacterial isolates and 8 of the 27 fungal isolates. The antimicrobial activity of tested acetonic plant extracts rosemary, henna, and licorice against MDR isolates was compared to the commercial antibiotic agents. Acetonic rosemary extract outperformed henna and licorice extracts in antibacterial activity, while licorice extract outperformed henna and rosemary extracts on antifungal activity. As a result, rosemary and licorice extracts were chosen to prepare a topical cream for further in vivo wound healing and histopathology. Based on the antimicrobial potential of acetonic plant extracts against MDR isolates, BI-41 and FI-17 were chosen for in vivo wound healing. BI-41 stands for the molecularly identified species Pseudomonas aeruginosa SSM-15, while FI-17 stands for molecularly identified species Aspergillus niger SSM-27.

Simulation experiments were conducted to establish which parameters can be adjusted to improve the effectiveness and safety of the nerve block. The outcome measures were block threshold (measure of effectiveness) and block threshold charge per phase (measure of safety). In vivo, the pudendal nerves in 11 male and 2 female anesthetized Sprague Dawley rats were stimulated in the range of 10 Hz to 40 kHz, and the effect on anal pressure was measured.

For this reason, huge efforts are being invested in discovering suitable blood biomarkers that would allow early diagnosis and treatment.

The aim of the study was to identify individual blood miRNAs that could be used as potential biomarkers for early diagnosis of lung cancer.\u0000\u0000\u0000METHODS\u0000This prospective study analyzed blood samples of 60 patients with early-stage lung cancer, and blood samples of 60 healthy individuals. All study patients with lung cancer had undergone radical pulmonary resection at the University Hospital Ostrava within the study period (2015-2017). Definitive diagnosis of lung cancer was confirmed by histopathology examination of the resected pulmonary specimen.
