Selenomethionine suppresses head and neck squamous cell carcinoma progression through TopBP1/ATR and TCAB1 signaling.

Head and neck squamous cell carcinoma (HNSCC) is a histological type of cancer originating from the head and neck. Selenium complexes have been considered as a potential treatment for HNSCC. Therefore, the present work focused on probing the mechanism of L-selenomethionine (SeMet) in HNSCC treatment. MTT and colony formation assays were carried out to analyze the survival rate and proliferation of HNSCC cells, respectively. TUNEL staining was performed to examine apoptosis of HNSCC cells. Additionally, qRT-PCR and Western blotting assays were performed to measure mRNA and protein levels, separately. SeMet treatment significantly hindered the survival and promoted the apoptosis of HNSCC cells in a dose- and time-dependently. SeMet administration promoted expression of TopBP1, ATR, H2AX, p-ATR and γ-H2AX, and suppressed that of TCAB1. Importantly, SeMet treatment suppressed the proliferation and facilitated the apoptosis of HNSCC cells, which were partly reversed by down-regulation of TopBP1 or up-regulation of TCAB1. The activation of SeMet to TopBP1/ATR signaling was rescued by TCAB1 up-regulating, and the inhibition of SeMet to TCAB1 expression was rescued by TopBP1 silencing. Our findings show that SeMet inhibits the proliferation of HNSCC cells and promotes their apoptosis by targeting TopBP1/ATR and TCAB1 signaling. SeMet is a potential method for HNSCC treatment.

Atomistic understanding of Ti3C2 MXene membrane performance for separation of nitrate ions from aqueous solutions

Water desalination, which is a reliable method for providing drinking water and a suitable solution, as well as the membrane filtration method in wastewater treatment, has increased significantly in recent years. In this research, the separation of nitrite and nitrate ions from aqueous solutions was done using the MXene membrane of the Ti3C2 type using molecular dynamics simulation. In this study, various parameters, such as pore size MXene structure, characteristics of cavities, applied pressure, and flux were investigated. To investigate the removal of toxic pollutants from water, water flux, potential mean force, distribution of water molecules, and density were investigated. The results showed that the amount of penetration through the membrane increased with the increase in pressure. It was observed that by applying pressure to the system, the number of water molecules accumulated in front of the membrane decreases because they quickly pass through the membrane, which indicates the positive effect of increasing pressure on the separation rate of molecules. The permeability of this membrane was several times higher than the existing membranes in the industry. So that Mexene membranes, which consist of at least two layers, can repel ions with 100% success.

Exosome-mediated Repair of Intervertebral Disc Degeneration: The Potential Role of miRNAs.

Intervertebral disc degeneration (IVDD) is a serious condition that manifests as low back pain, intervertebral disc protrusion, and spinal canal stenosis. At present, the main treatment methods for IVDD are surgical interventions such as discectomy, total disc replacement, and spinal fusion. However, these interventions have shown limitations, such as recurrent lumbar disc herniation after discectomy, lesions in adjacent segments, and failure of fixation. To overcome these shortcomings, researchers have been exploring stem cell transplantation therapy, such as mesenchymal stem cell (MSC) transplantation, but the treatment results are still controversial. Therefore, researchers are in search of new methods that are more efficient and have better outcomes. The exosomes from stem cells contain a variety of bioactive molecules that mediate cell interactions, and these components have been investigated for their potential therapeutic role in the repair of various tissue injuries. Recent studies have shown that MSC-derived miRNAs in exosomes and vesicles have therapeutic effects on nucleus pulposus cells, annulus fibrosus, and cartilage endplate. miRNAs play a role in many cell activities, such as cell proliferation, apoptosis, and cytokine release, by acting on mRNA translation, and they may have immense therapeutic potential, especially when combined with stem cell therapy. This article reviews the current status of research on intervertebral disc repair, especially with regard to the latest research findings on the molecular biological mechanisms of miRNAs in MSC-derived exosomes in intervertebral disc repair.

Study on Bonding Characteristics of Aluminum Alloy Treated by Plasma Electrolytic Oxidation Process and Polymer Resin Bonded by Direct Injection Molding

Aluminum alloy and polymer resin hybrid bonding technology is essential for lightweight mobile phone frames and automotive components. Recently, there has been extensive research on a method of bonding metals and polymer resins by treating the metal surface and then direct injection molding. However, this method requires separate surface treatment of the aluminum alloy after bonding to enhance its corrosion resistance. This paper studies the use of Plasma Electrolytic Oxidation, one of the surface treatment methods for aluminum, to achieve the bonding of aluminum and polymer resin in a single surface treatment step while ensuring high corrosion resistance. We conducted research to investigate optimal conditions by adjusting the process variables of Plasma Electrolytic Oxidation, in order to achieve integration with the polymer resin and measure the bonding strength and corrosion resistance. The surface characteristics of each Plasma Electrolytic Oxidation condition were analyzed using scanning electron microscopy and atomic force microscope equipment, while the bonding strength was measured using universal testing machine equipment. The corrosion characteristics were evaluated by measuring the corrosion resistance in a saltwater solution.

Research Progress on the Mechanism of Intestinal Barrier Damage and Drug Therapy in a High Altitude Environment.

The plateau is a typical extreme environment with low temperature, low oxygen and high ultraviolet rays. The integrity of the intestinal barrier is the basis for the functioning of the intestine, which plays an important role in absorbing nutrients, maintaining the balance of intestinal flora, and blocking the invasion of toxins. Currently, there is increasing evidence that high altitude environment can enhance intestinal permeability and disrupt intestinal barrier integrity. This article mainly focuses on the regulation of the expression of HIF and tight junction proteins in the high altitude environment, which promotes the release of pro-inflammatory factors, especially the imbalance of intestinal flora caused by the high altitude environment. The mechanism of intestinal barrier damage and the drugs to protect the intestinal barrier are reviewed. Studying the mechanism of intestinal barrier damage in high altitude environment is not only conducive to understanding the mechanism of high altitude environment affecting intestinal barrier function, but also provides a more scientific medicine treatment method for intestinal damage caused by the special high altitude environment.

Liposomal Nano-Based Drug Delivery Systems for Breast Cancer Therapy: Recent Advances and Progresses.

Breast cancer is a highly prevalent disease on a global scale, with a 30% incidence rate among women and a 14% mortality rate. Developing countries bear a disproportionate share of the disease burden, while countries with greater technological advancements exhibit a higher incidence. A mere 7% of women under the age of 40 are diagnosed with breast cancer, and the prevalence of this ailment is significantly diminished among those aged 35 and younger. Chemotherapy, radiation therapy, and surgical intervention comprise the treatment protocol. However, the ongoing quest for a definitive cure for breast cancer continues. The propensity for cancer stem cells to metastasize and resistance to treatment constitute their Achilles' heel. The advancement of drug delivery techniques that target cancer cells specifically holds significant promise in terms of facilitating timely detection and effective intervention. Novel approaches to pharmaceutical delivery, including nanostructures and liposomes, may bring about substantial changes in the way breast cancer is managed. These systems offer a multitude of advantages, such as heightened bioavailability, enhanced solubility, targeted tumor destruction, and diminished adverse effects. The application of nano-drug delivery systems to administer anti-breast cancer medications is a significant subject of research. This article delves into the domain of breast cancer, conventional treatment methods, the incorporation of nanotechnology into managerial tactics, and strategic approaches aimed at tackling the disease at its core.

Stanniocalcin-2: A Potential Predictor of Residual Breast Cancer After Neoadjuvant Chemotherapy

Compared to patients of pathological complete response (pCR), patients of residual lesion afterwards neoadjuvant chemotherapy (NAC) have worse prognosis and higher distant metastasis. Irrespective, there exists limited data on effective indicators and treatment methods for these patients. In our study, we evaluated the relationship between stanniocalcin-2 (STC2) marker and the prognosis of breast cancer patients of residual lesion after receiving NAC. The relationship between STC2 and patients’ prognosis was evaluated by transcriptome analysis. The impact of the level of STC2 on cell migration, invasion, and proliferation was evaluated at the cellular level. Immunohistochemistry was performed on 293 patients with residual disease after NAC to assess STC2 protein levels. The relationship between STC2 and survival rate was estimated using Cox regression model and Kaplan Meier analysis. The results demonstrated that high level of STC2 significantly inhibited migration, invasion, and proliferation of breast cancer cells. Compared to patients with low STC2, high STC2 were directly proportional to overall survival (OS) and disease-free survival (DFS) (OS: 86.96 vs. 84.62 months, P = 0.017 DFS: 77.33 vs. 66.95 months, P-value < 0.001). In conclusion, our research suggested that the of level STC2 may be a promising prognostic marker or therapeutic targe for breast cancer patients with residual lesion after NAC.

Metaverse ve Psikiyatri: Bir Gözden Geçirme

Today, with the development of technology, the concept of the virtual world is gaining more and more importance. "Metaverse", which has become popular in recent years, aims to provide an environment where people can interact, do business, have fun and even live in the digital world. Metaverse, which has become increasingly popular in recent years, offers many different uses in the field of mental health. However, we do not yet have enough information about the effects of this technology on mental health. The effect of Metaverse on mental health has been the subject of many researches that it can be used in areas such as the treatment of psychological disorders, stress reduction, self-confidence, and development of social interaction skills. The biggest advantage of using Metaverse for psychiatric treatment is that the virtual world is separated from the real world. Therefore, the stress, anxiety and other emotional reactions experienced during treatment have no real-life consequences. In addition, the therapist is easier to access in the virtual world and can help patients adapt to treatment more easily. However, the use of Metaverse for psychiatric treatment also has some disadvantages. For example, this method of treatment may be an unrealistic experience for some patients and not effective enough for others. Also, this treatment modality has limited accessibility as it requires high cost equipment and technology. In particular, there has not been enough research on the relationship between the use of Metaverse in the diagnosis and treatment of psychiatric diseases. More research is needed on the effect of Metaverse on mental health. In particular, more studies are needed on its long-term effects and effects on different people. In this review, studies investigating the potential relationship between Metaverse technology and psychiatry and how this technology can be used in the psychiatric field are reviewed.

Development of a New Non-Invasive Approach to Treat of Infantile Hemangioma with Growth-Inhibiting Endogenous Factors (Non-Invasive Approach to Treat of Infantile Hemangioma with Endogenous Factors)

Background: Infant hemangioma is a benign vascular tumor, the main reason for the development of which is genetic disorders occurring in embryogenesis. It should be noted that all methods of treating the disease, both general and local, have potential negative risks and side effects. The identification of endogenous regulatory factors and researching the possibilities of using them for treatment is relevant. There is the thermostable proteins complex (TPC) which has been identified in the cells of phylogenetically distant almost all organisms, which has the ability to decrease the mitotic activity of cells by inhibition of transcription. In the experimental model of hemangioma, it has been established that inhibition of capillary growth can only be achieved by injection. The aim of the work was to develop a new, less invasive method of hemangioma treatment with endogenous factors.

Factorial experimental design for removal of Indigo Carmine and Brilliant Yellow dyes from solutions by coagulation

Textile and food industries produce huge amounts of wastewaters containing dye residues. When these wastewaters are discharged to receiving surface waters like as lakes and rivers, aesthetically unpleasant situations form. Therefore, these wastewaters should be treated. Wastewater treatment is sometimes an expensive operation and cheap methods should be developed. The removal of Indigo Carmine (I.C., Acid dye) and Brilliant Yellow (B.Y., Azo dye) from synthetically prepared solutions was studied by coagulation using iron chloride salt in a batch reactor at room temperature. As an experimental approach, two leveled factorial design with three factors was applied as a function of pH (4-12), iron chloride amount (0.1-0.4 g/500 mL) and dye concentration (100-200 mg/L). Low pHs supported to removal of these two dyes. The results showed that 100% I.C. dye removal and 90.5% B.Y. dye removal were achieved. The all parameters were statistically insignificant for both the dyes. Indigo Carmine and Brilliant Yellow dyes were removed from solutions successfully. The applied treatment method was evaluated as promising due to low sludge production, low cost, low coagulation duration and high performance. A time span of 5 minutes was found as enough for removals of both of the dyes. After treatment of I.C. and B.Y. dyes by coagulation, the coagulated dyes were determined as unreusable due to iron complex by these dyes. Flocculation was found to be ineffective. A continuous flow reactor was successfully adopted for these dyes.

Evaluation of characterization and adsorption kinetics of natural organic matter onto nitric acid modified activated carbon

Natural organic substances (NOM) found in drinking water are a major contributor to disinfectant by-product formation and are potentially toxic to humans. Traditional water treatment techniques may not always effectively treat NOMs. Therefore, an advanced treatment method such as adsorption can be inexpensive, simple and efficient. The selected adsorbent's and the NOMs properties both affect the removal effectiveness of the adsorption method. Activated carbon (AC), which is widely used in real-scale water treatment plants, has been modified and used in recent years In order to oxidize the porous carbon surface, raise its acidic qualities, eliminate mineral components, and enhance the surface's hydrophilic qualities. In this research, AC was modified with nitric acid (M-PAC) and NOM removal was investigated. In addition, it is discussed how the modification with nitric acid changes the adsorbent structure and chemistry. A morphology with smooth and irregular voids was observed as a result of nitric acid modification of the original AC by SEM analysis. The particle size increased from 387.65 nm to 502.07 nm for the M-PAC adsorbent. The FTIR spectrum indicates that structures connected to aromatic rings get formed in the M-PAC adsorbent as a result of the modification. The highest NOM removal for the original powdered activated carbon (PAC), 47%, was observed at 36 hours of contact time. On the other hand, M-PAC adsorbent achieved 40% NOM removal at contact times of 72 hours and above. It was concluded that the pseudo-second order kinetic model better represented NOM adsorption for both adsorbents.

Current Trends in the Treatment of Misophonia

Misophonia is a disorder characterized by emotional and physiological responses that occur in response to certain auditory stimuli. Visual, tactile, and olfactory stimuli, primarily oral and nasal sounds such as eating, nose, and respiratory sounds, reveal misophonic responses. People with misophonia may have difficulty in social interactions, and work or school performance may be adversely affected. Misophonia symptoms can also cause anxiety, depression, and other mental health problems. Physiological reactions in the body, such as pain, sweating, tachycardia, hot flashes, and breathing difficulties, negatively affect people's physical health. For this reason, people's physical and mental health and quality of life are significantly affected. The absence of agreed diagnostic criteria for the diagnosis of misophonia and the lack of sufficient data to classify it as a psychiatric disorder has led to the lack of validated treatment guidelines. However, there are treatment recommendations discussed in the literature for misophonia, which has a prevalence of 20% in a limited number of studies and negatively affects the functionality of the individual. In the management of misophonia, tinnitus re-education therapy (TRT) was used as audiological treatment, antidepressants, and anxiolytics were used as pharmacological treatment and cognitive behavioral therapies were used as therapy. Other suggested treatment recommendations are neural remodeling technique, sequential remodeling hypnotherapy, trauma prevention technique, and trauma and tension reduction exercises. This review aims to present the treatment approaches available in the literature together and to understand the need for experimental evidence for treatment methods.

Human Umbilical Cord Mesenchymal Stem Cells Combined with Dehydroepiandrosterone Inhibits Inflammation-Induced Uterine Aging in Mice.

With the postponement of the reproductive age of women, the difficulty of embryo implantation caused by uterine aging has become a key factor restricting fertility. However, there are few studies on protective interventions for naturally aging uteri. Although many factors cause uterine aging, such as oxidative stress (OS), inflammation, and fibrosis, their impact on uterine function manifests as reduced endometrial receptivity. This study aimed to use a combination of human umbilical cord mesenchymal stem cells (hUC-MSCs) and dehydroepiandrosterone (DHEA) to delay uterine aging. The results showed that the combined treatment of hUC-MSCs + DHEA increased the number of uterine glandular bodies and the thickness of the endometrium while inhibiting the senescence of endometrial epithelial cells. This combined treatment alleviates the expression of OS (reactive oxygen species, superoxide dismutase, and GSH-PX) and proinflammatory factors (interleukin [IL]-1, IL6, IL-18, and tumor necrosis factor-α) in the uterus, delaying the aging process. The combined treatment of hUC-MSCs + DHEA alleviated the abnormal hormone response of the endometrium, inhibited excessive accumulation and fibrosis of uterine collagen, and upregulated uterine estrogen and progesterone receptors through the PI3K/AKT/mTOR pathway. This study suggests that uterine aging can be delayed through hUC-MSCs + DHEA combination therapy, providing a new treatment method for uterine aging.

Surgical and non-operative treatment of acute complicated diverticulitis in a COVID hospital

Surgical treatment of acute abdomen during the SARS-CoV-2 pandemic was accompanied by an extremely high mortality rate, however, only a few studies have presented the results of acute inflammatory complications of diverticular disease (AICDD).AIM: analysis of treatment of AICDD in a COVID-19 hospital.PATIENTS AND METHODS: the retrospective study included 78 patients with acute diverticulitis (AD) from a COVID hospital, confirmed by CT or intraoperative revision. Assessment of COVID pneumonia, comorbidities, organ dysfunction, CT findings, peritonitis, treatment methods, and in-hospital mortality among patients was performed.RESULTS: organ dysfunction of ≥ 1 point on the qSOFA scale was detected in 59.0% of the patients. According to CT data, abdominal distant gas was detected in 48 (61.5%) patients, and pericolic gas in 14 (17.9%) patients. Segmental colon resection was performed in 60 (76.9%) patients, laparoscopic lavage (LL) of the abdominal cavity — in 3, non-operative treatment (NOT) with drainage of fluid collections — in 6, and only NOT in 10 patients. Most patients with distant or pericolic gas were operated on within an average time of 1 [0; 3.5] hours after admission. Diffuse peritonitis was detected during surgery in 45 (75%) of them. After resection, organ dysfunction of ≥ 2 points on the SOFA scale developed or progressed in 52 (86.7%) patients. The overall mortality rate was 48.7%, and the postoperative mortality was 63.3%. All patients (n = 38) died after segmental colon resection. Successful NOT was achieved in 4 patients with pericolic gas and 3 patients with distant gas.CONCLUSION: surgery for AICDD in patients with COVID-19 is associated with extremely high mortality, therefore, in the absence of obvious signs of diffuse peritonitis, initial non-operative treatment may be life-saving.
