Variable outcomes have been associated with several factors including cancer pathology, experimental procedure, MSC source tissue, and individual genetic differences. It is also known that MSCs exert their therapeutic effects with various paracrine factors released from these cells. The profiles of the factors released from MSCs are altered by heat shock, hypoxia, oxidative stress, starvation or various agents such as inflammatory cytokines, and their therapeutic potential is affected. In this study, the antitumor potential of conditioned media (CM), which contains paracrine factors, of mild hyperthermia-stimulated mesenchymal stromal cells derived from lymphoid organ tonsil tissue (T-MSC) was investigated in comparison with CM obtained from T-MSCs grew under normal culture conditions. CM was obtained from T-MSCs that were successfully isolated from palatine tonsil tissue and characterized. The cytotoxic effect of CM on the growth of hematological cancer cell lines at different concentrations (11 and 12) was demonstrated by methylthiazoldiphenyl-tetrazolium bromide analysis. In addition, the apoptotic effect of T-MSC-CM treatment was evaluated on the cancer cells using Annexin-V/PI detection method by flow cytometry. The pro/anti-apoptotic and cytokine-related gene expressions were also analyzed by real-time polymerase chain reaction post T-MSC-CM treatment. In conclusion, we demonstrated that the factors released from hyperthermia-stimulated T-MSCs induced apoptosis in hematological cancer cell lines in a dose-dependent manner. Importantly, our results at the transcriptional level support that the factors and cytokines released from hyperthermia-stimulated T-MSC may exert antitumoral effects in cancer cells by downregulation of IL-6 that promotes tumorigenesis. These findings reveal that T-MSC-CM can be a powerful cell-free therapeutical strategy for cancer therapy.
The aims of the Critical Care Cardiology Trials Network (CCCTN) are to develop a registry to investigate the epidemiology of cardiac critical illness and to establish a multicentre research network to conduct randomised clinical trials (RCTs) in patients with cardiac critical illness.
The CCCTN was founded in 2017 with 16 centres and has grown to a research network of over 40 academic and clinical centres in the United States and Canada. Each centre enters data for consecutive cardiac intensive care unit (CICU) admissions for at least 2 months of each calendar year. More than 20000 unique CICU admissions are now included in the CCCTN Registry. To date, scientific observations from the CCCTN Registry include description of variations in care, the epidemiology and outcomes of all CICU patients, as well as subsets of patients with specific disease states, such as shock, heart failure, renal dysfunction, and respiratory failure. The CCCTN has also characterised utilization patterns, including use of mechanical circulatory support in response to changes in the heart transplantation allocation system, and the use and impact of multidisciplinary shock teams. Over years of multicentre collaboration, the CCCTN has established a robust research network to facilitate multicentre registry-based randomised trials in patients with cardiac critical illness.
The CCCTN is a large, prospective registry dedicated to describing processes-of-care and expanding clinical knowledge in cardiac critical illness. The CCCTN will serve as an investigational platform from which to conduct randomised controlled trials in this important patient population.

Latinos are underrepresented in brain autopsy research on Alzheimer's disease and related dementias (ADRD). The study's purpose is to identify Latinos' attitudes about brain donation (BD) to inform methods by which researchers can increase autopsy consent.
Forty Latinos (mean age 59.4 years) completed a semi-structured interview and were presented with educational information about BD. Participants completed a questionnaire assessing their understanding of BD and willingness to donate their brain for research.
Among participants, there was near unanimous support for BD to study ADRD after hearing educational information. However, prior to the information presented, participants reported a lack of knowledge about BD and demonstrated a possibility that misunderstandings about BD may affect participation.
While nearly all study participants agree that donating is beneficial for research and for future generations, the lack of BD information must be addressed to help support positive attitudes and willingness for participation.

Tricholoma matsutake is an economically important fungus in Asian countries and usually inhabits forests primarily composed of Pinus densiflora (Japanese red pine). In this study, to understand the mycorrhizal association between T. matsutake and P. densiflora, genes specifically expressed in mycorrhiza compared with those expressed in mycelia and fruiting bodies were identified by RNA-seq. This revealed that genes for chromatin, proteasomes, signal transduction, pheromones, cell surface receptors, cytoskeleton, RNA processing and transporters from T. matsutake were highly expressed in mycorrhiza. It also identified 35 mycorrhiza-induced small secreted proteins (MiSSPs) that were highly expressed in mycorrhiza. Meanwhile, genes for proteases, defence-related proteins, cell-wall degradation, signal transduction, pinene synthesis, plant hormones and transporters from P. densiflora were highly expressed in mycorrhiza. These genes may be involved in mycorrhizal formation and maintenance. A MiSSP, 1460819, was highly expressed in mycorrhiza, and this expression was maintained for 24 months. These results provide insight into the mycorrhizal association between T. matsutake and P. densiflora.Venous thrombosis is a semi-solid formation of blood components that coalesce in the venous system, and the pathological process of its formation is called venous thrombosis. The deep veins of the lower extremities are a common site of prevalence, and the clinical diagnosis of lower extremity deep vein thrombosis can occur independently or as a complication of other diseases. There is a clear link between inflammation and coagulation/anticoagulation, with inflammatory mechanisms upregulating pro-inflammatory factors, downregulating natural anticoagulant substances, and inhibiting fibrinolytic activity; systemic inflammation is a strong pro-thrombotic stimulus; and in vivo, natural anticoagulant substances not only prevent thrombosis, but also deter inflammatory processes. The interconnection between inflammation and coagulation plays an important role in venous thrombosis. In this study, we analyzed the relationship between inflammatory markers CRP and Fg, FVIIIC and FIXC by measuring plasma CRP concentration between the two groups, and the correlation between CRP and FVIIIC, FIXC and Fg was analyzed. Polymerase chain reaction-restriction enzyme segment length polymorphism nucleotide typing technique was used to detect the relationship between CRP 1059G/C gene polymorphism and DVT, to further search for risk factors of venous thrombosis, thus providing new ideas for the future prevention and treatment of this disease in clinical practice.This study was performed to evaluate the histological changes in the cornea after accelerated collagen crosslinking. In this regard, the right eyes of 7 New Zealand albino rabbits weighing 1.5 to 2 kg were studied. The right eye was considered the case group, and the left eye was considered the control group. The right eye epithelium was removed, riboflavin 0.1 solutions (10 mg riboflavin-5 phosphate in 10 ml dextran-T-500, 20%) were shaken every three minutes for 30 minutes and exposed to UVA for 10 minutes, and crosslinking was performed. All rabbits were euthanized and histologically evaluated. Apoptosis was assessed using the tunnel method. The results showed a significant difference in the mean percentage of apoptotic cells in the treatment and control groups. In both endothelial cells and keratocytes in the treated cornea, the number of apoptotic cells was significantly higher than in the control group. In the general examination of the cornea (keratocytes and endothelium) in the right eye of rabbits, the mean and standard deviation of the percentage of apoptotic cells was 18.39 ± 3.4 and in the left eye was 6.37 ± 1.8. The apoptosis results of keratocytes in the right eye showed that the mean and standard deviation for the percentage of apoptotic keratocytes was 2.86 ± 1.07, which was significantly higher than in the left eye (0.53 ± 0.43) (P less then 0.001). The mean and standard deviation of endothelial apoptotic cells in the right and left eyes were 86.2 and 53.5, respectively, statistically significant (P = 0.026). Although CXL is a reliable method of preventing the progression of keratoconus disease, there is still a risk of endothelial cell damage and related complications due to endothelial cell damage, and further studies are needed.Pulpotomy is the typical treatment for keeping deciduous teeth until exfoliation. Formocresol is one of the most common materials used in dental pulpotomy. Due to the side effects of this drug, its replacement with other substances seems necessary. Therefore, this study compared clinical and histopathological evaluations of primary pulpotomy molars with formocresol and biodentine. In this clinical trial, 66 second-mandibular deciduous molars of children aged 6 to 9 years who met the criteria for pulpotomy were selected. Pulpotomy of the teeth was performed using formocresol and biodentine. For each patient, one tooth was randomly placed in the pulpotomy group with formocresol. The other tooth was placed in the pulpotomy group with biodentine. Then the crowns of the teeth were restored with stainless steel veneer. We recorded clinical and radiographic results of these teeth over six months and one year. The teeth were then extracted after 12 months, and hematoxylin-eosin staining was performed for histopatholoe formocresol group. There was a significant difference between the two groups regarding necrosis (P = 0.032). There was no significant difference between the two groups regarding abscess (P> 0.05). According to the obtained results, biodentine could be a suitable alternative for mandibular second molar pulpotomy.Ovarian cancer is one of the most common malignancies in women and is also the fifth leading cause of cancer death in women worldwide. In recent years, the survival rate of patients with this disease has been long, and at the same time, more emphasis is on their quality of life. Therefore, the present study was conducted to investigate the effect of supportive and educational care of nurses on the life quality of patients with ovarian cancer. The expression of the HE4 gene was also evaluated as a diagnostic marker of ovarian cancer to assess the role of supportive and educational care of nurses in improving the physical health of these patients. In this study, which was a quasi-experimental study, 45 patients with ovarian cancer participated. The instrument was demographic information and quality of life questionnaires related to Beckman Institute, which were completed in two stages before and after patients' training and support sessions. Taselisib manufacturer HE4 gene expression was also assessed by Real-time PCR technique. Finally, the obtained data were analyzed using SPSS software and statistical tests.
