Uncontrolled cell proliferation is a hallmark of breast cancer (BC), a malignant disease that frequently results in the development of tumors. With distinct genetic profiles and clinical consequences, it has multiple molecular subtypes, such as triple-negative, HER2-positive, luminal A, and luminal B. This study investigated the relationship between the expression of the microRNAs miR-195 and miR-206 in a sample of female BC patients from Iraq and their illness features and demographic distribution. Most BC cases occur in women between the ages of 40 and 59. The study included 60 patients and 60 healthy women. There were no appreciable variations between the right and left breast placements, and the average age of BC patients was 49.27 ± 10.66. Luminal A was the most prevalent molecular subtype of invasive ductal carcinoma (IDC), which was the most prevalent kind overall. The highest rates of BC were found in stages II and III, at 40% and 36%, respectively. While there were no discernible changes between the luminal a, luminal B, and HER2 subtypes, RT-qPCR using miR-16 as an internal reference revealed that miR-195 was markedly increased in BC patients relative to controls. With no discernible variations between molecular subtypes, miR-206 was downregulated in BC patients; however, it was significantly downregulated in stages II, III, and IV in comparison to stage I. These results imply that miR-195 and miR-206 might be involved in the onset and development of BC.

Despite the large volume of empirical data on the effects of magnetic fields on living organisms, there are almost no studies showing the possibility of the existence of magnetic effects in processes outside the cell or in vitro. The protein folding process in a cell can be sensitive to magnetic fields. We the first time experimentally demonstrated the possibility of biochemical effects of extremely low frequency magnetic fields and hypomagnetic fields on chemical renaturation using hen egg-white lysozyme as an example. The degree of lysozyme renaturation was estimated at different magnetic conditions by fluorescence intensity and enzymatic activity. The extremely low frequency magnetic field (50 Hz, 40 μT) accelerates the renaturation compared to the control and a hypomagnetic field (less than 40 nT). The effects of hypomagnetic and extremely low frequency magnetic field on the protein fluorescence spectrum were opposite. It confirms the participation of the recently described level mixing mechanism in the implementation of magnetobiological effects. The magnetic nanoparticles abolished the effects of extremely low frequency magnetic and hypomagnetic fields fluorescence and activity of lysozyme, which indicates their ability to modulate magnetobiological effects. The results obtained expand fundamental ideas about the mechanisms of action of magnetic fields on isolated protein molecules and can be useful in the practice of using magnetic nanoparticles in biomedicine.

This study examined female rats' physiological and histological responses to cadmium chloride and lead acetate. Histological lung tissue examinations included oxidative stress and antioxidant status. Six female rat groups were studied. A group that served as a control was provided with water that had been distilled. The dosage of cadmium chloride that was administered to the second group was 5 mg/kg, whereas the dosage that was administered to the third group was 10 mg/kg. The fourth group received a dosage of lead acetate that was 50 mg/kg, whereas the fifth group received 100 mg/kg. All of the standard concentrations of lead acetate and cadmium chloride were administered to the sixth group in accordance with their protocol. Following thirty days of treatment of cadmium chloride and lead acetate to rats, the levels of oxidative indicators like MDA and 8-OHDG showed a substantial increase (P < 0.05). On the other hand, the levels of antioxidants like GSH, SOD, and CAT showed a significant drop (P ≤ 0.05 following the administration of these substances. Histological research has shown that exposure to cadmium chloride and lead acetate is associated with an increased risk of blood clots in the lungs as well as a thickening of the pulmonary alveolar wall. This is in comparison to a control group. These results demonstrate that cadmium chloride and lead acetate treatment adversely affected lung tissue's physiological and histological properties. The researchers discovered that the detrimental effect was more pronounced when the two drugs were administered concurrently to rats.

This study aimed to evaluate the efficacy of High-Frequency Transcutaneous Electrical Nerve Stimulation (TENS) in combination with Complex Decongestive Physical Therapy (CDPT) on lower limb lymphedema. Every participant provided informed consent for the randomized controlled trial. The trial was conducted at Ahmed Maher Teaching Hospital and High-Top Clinic in Egypt. 60 patients with secondary lower limb lymphedema, ages 35 to 65, were involved in the trial and were split into two groups at random. Group A received CDPT and High-Frequency TENS, while Group B received CDPT only. Both interventions were administered thrice weekly for eight weeks. A non-flexible tape was used to assess the limb girth as the major result; the Lymphedema Quality of Life Questionnaire (LYMQOL) was used as a secondary outcome. ANOVA tests were used in the statistical analysis to compare the pre and post-treatment outcomes within and across groups. The findings revealed that both groups had significantly lower limb girth and improved LYMQOL scores, with Group A showing more improvements than Group B (p < 0.05). The results indicate that for patients with lower limb lymphedema, the combination of High-Frequency TENS and CDPT is superior to CDPT alone in terms of limb girth reduction and improved quality of life. This combination of therapies may be a useful strategy for treating lymphedema and enhancing patient outcomes.
