In children, asthma is the most prevalent chronic disease. Due to the similarities between the symptoms of these two conditions, we sought to assess the general health status of pediatric patients with asthma and their COVID-19-related difficulties during the first year of the pandemic in Iran. We collected data for this study by administering a questionnaire to the parents of 200 children with asthma who were registered in the database of the Asthma Clinic at a tertiary medical center in Tehran, Iran. Forty-five (22.5%) of 200 patients were suspected of having COVID-19, 11 (24.4%) underwent polymerase chain reaction (PCR) testing, and 10 (90.9%) assays were positive. During the first year of the pandemic, 41 patients (20.5%) were referred to a medical center at least once, with 31.7% due to an asthma attack. One hundred eighty-nine patients (94.5%) reported an improved disease status than the previous year, and only 31 patients (15.5%) were using asthma-related medications such as Salbutamol. The estimated mean Asthma Control Test (ACT) scores for two age categories, 4-11 years and 12-18 years, were 25.55±2.27 and 23.28±3.31, respectively, indicating satisfactory disease control.

The current study evaluated serum antibody levels against previously determined immunogenic OmpA peptides from A baumannii in ICU staff. Serum samples were collected from 62 ICU staff members (representing the exposed group), healthy controls (representing the nonexposed group), and patients with systemic lupus erythematosus (SLE) (as controls for nonspecific antibody reactions). After excluding the cross-reactive antibodies via Escherichia coli lysate pretreatment, all the samples were assessed in the vicinity of A baumannii lysate by enzyme-linked immunosorbent assay (ELISA). All the positive samples were assessed for interaction with previously designed and selected peptides using ELISA. The protective potential of positive serum antibodies was surveyed in vitro using an opsonophagocytic study. The most antibody positive samples against one of the dominant peptides were determined in the ICU personnel (75%).  SLE serum samples did not react with candidate peptides. The strongest positive reaction was observed in serum treatment with one of the OmpA peptides (No. 5) with significant differences compared to other designed peptides. Our findings showed that ICU samples have substantially higher antibody levels than the nonexposed group; Positive samples show strong results in the opsonophagocytosiis assay. This study demonstrates A baumannii colonization at human mucosal surfaces, especially in exposed healthy workers.

Here, we investigated how the expression of programmed cell death-ligand 1 (PD-L1) in the tumor microenvironment varied in different RT regimens with the same biologically effective dose. In this study, female BALB/c mice inoculated with CT26 tumor cells were irradiated with 3 different RT regimens using the same BED of 40 gray (Gy).

All treated groups expressed PD-L1, but the group receiving single ablative high-dose RT showed higher expression compared to the other groups.

The mammalian target of the rapamycin (mTOR) pathway harbors several established oncogenes and tumor suppressors. The same signaling molecules and growth factors, such as vascular endothelial growth factor (VEGF), contributing to cancer development and progression play a part in fibroblast proliferation, myofibroblast differentiation, and the production of extracellular matrix in IPF development as well. The expression of candidate genes acting upstream and downstream of mTORC1, as well as Vegf and low-density lipoprotein receptor related protein 1(Lrp1), was assessed using specific primers and quantitative polymerase chain reaction (qPCR) within the lung tissues of bleomycin (BLM)-induced IPF mouse models. Lung fibrosis was evaluated by histological examinations and hydroxyproline colorimetric assay. BLM-exposed mice developed lung injuries characterized by inflammatory manifestations and fibrotic features, along with higher levels of collagen and hydroxyproline. Gene expression analyses indicated a significant elevation of regulatory associated protein of mTOR (Raptor), Ras homolog enriched in brain (Rheb), S6 kinase 1, and Eukaryotic translation initiation factor 4E-binding protein 1 (4Ebp1), as well as a significant reduction of Vegfa, Tuberous sclerosis complex (Tsc2), and Lrp1; no changes were observed in the Tsc1 mRNA level. Our findings support the elevation of S6K1 and 4EBP1 in response to the TSC/RHEB/mTORC1 axis, which profoundly encourages the development and establishment of IPF and cancer.

The present study investigated the levels of inflammatory cytokines, tumor necrosis factor-α (TNF-α), interleukin-1 (IL-1), and interleukin-6 (IL-6) in patients with major depression or bipolar disorder during depressive episodes (BDDE) before and after a 6-month pharmaceutical intervention.
