Somatic mutation, methylation alteration, and homozygous CNV of eight PRGs barely occurred in PAAD samples. As for therapeutic correlation, PR risk score may not predict the efficacy of PD-1/L1 inhibitors and was weakly associated with multiple drug susceptibilities. Finally, the biofunctions of toll like receptor 3 (TLR3) in pancreatic cancer (PC) cells were investigated through qPCR, MTT, colony formation, and Transwell assays. Overexpression of TLR3 could promote the proliferation, migration, and invasion of PC cells. In conclusion, PRGs play crucial roles in prognosis, progression, and immune microenvironment of PAAD. TLR3 is expected to be a promising therapeutic target.Titanium dioxide (TiO2) nanoparticles are indispensable for daily life but induce acute inflammation, mainly via inhalation exposure. TiO2 nanoparticles can be phagocytosed by alveolar macrophages (AMs) in vivo and cause necroptosis of exposed cells in vitro. However, the relationship between localization of TiO2 nanoparticles in the lungs after exposure and their biological responses including cell death and inflammation remains unclear. This study was conducted to investigate the intra/extracellular localization of TiO2 nanoparticles in murine lungs at 24 h after intratracheal exposure to rutile TiO2 nanoparticles and subsequent local biological reactions, specifically necroptosis of AMs and lung inflammation. We found that TiO2 exposure induced leukocyte migration into the alveolar region and increased the secretion of C-C motif ligand (CCL) 3 in the bronchoalveolar lavage (BAL) fluid. A combination of Raman spectroscopy and staining of cell and tissue samples confirmed that AMs phagocytose TiO2. AMs that phagocytosed TiO2 nanoparticles showed necroptosis, characterized by the expression of phosphorylated mixed lineage kinase domain-like protein and translocation of high mobility group box-1 from the cell nucleus to the cytoplasm. In primary cultured AMs, TiO2 also induced necroptosis and increased the secretion of CCL3. Necroptosis inhibitors suppressed the increase in CCL3 secretion in both the BAL fluid and culture supernatant of AMs and suppressed the increase in leukocytes in the BAL fluid. These data suggest that necroptosis of AMs that phagocytose TiO2 nanoparticles is involved as part of the mechanism by which TiO2 induces acute lung inflammation.Although coronavirus disease-2019 (COVID-19) is mainly a respiratory system disease, neurological complications due to peripheral and central nervous system involvement may be seen in these patients. In this case report, we described a patient with isolated abducens nerve palsy after COVID-19. The patient was a healthy 28-year-old man who developed isolated abducens nerve palsy 10 days after COVID-19. He had no systemic risk factors. He had 20 PD left esotropia (ET) at distance and 16 PD left ET at near in primary position and ET increasing to 25 PD in left gaze. He had left abduction deficiency. His cranio-orbital magnetic resonance imaging findings were normal. He was diagnosed as left isolated abducens nerve palsy and his findings were recovered after 2 months. COVID-19 may cause ocular motor nerve palsies. Although the pathological mechanism remains unclear, direct viral invasion, inflammatory and immune mechanisms may play role. Further case reports and studies are needed to support these findings.
Substantial evidence is emerging regarding the broad societal and psychological impacts of the COVID-19 pandemic, but little is known about whether infected individuals are differently affected.
We evaluated psychological differences between individuals who do vs. do not report testing positive for COVID-19.
An online survey was offered to adults (≥18 years) who were diagnosed with COVID-19 by a provider within a large integrated-delivery healthcare system, enrolled in COVID-19-related clinical trials at the healthcare system, or responded to targeted local distribution. Measures assessed included the 8-item Patient Health Questionnaire depression scale, Generalized Anxiety Disorder 7-item Scale, and Posttraumatic Diagnostic Scale for DSM-5.
Of 487 respondents, 43% reported testing positive for COVID-19, including 11% requiring hospitalization. Overall rates of general anxiety disorder and posttraumatic stress were 34% and 16%, respectively, with no significant differences between groups. Prevalence of depression was higher among respondents reporting a positive COVID-19 test (52% vs. 31%). This difference persisted after controlling for respondent characteristics (odds ratio = 3.7,
< 0.01).
People who report testing positive for COVID-19, even those not requiring hospitalization, have increased risk for depression. Mental health care screening and services should be offered to individuals testing positive, facilitating early intervention.

Mentorship programs in health professional education are often characterized as a mutually beneficial relationship between mentor and mentee, but little is known about benefits for mentors. Mentors can be health professionals, academic faculty, other students (peers), and patients (health mentors). We studied the benefits that health mentors (people with chronic health conditions or disabilities, or a caregiver) get from mentoring students, and the contextual factors that contribute to, or explain these benefits.
We surveyed 72 health mentors who had mentored between one and eight cohorts of students from different health professions in the health mentors program at the University of British Columbia. Using a contextual-developmental framework of mentorship, we analyzed mentors' responses to open-ended questions about how they benefit from the program.
Benefits fit into three categories generativity (guiding the next generation), transformation (personal growth and reflection), and 'career' development (new activities resulting from increased self-efficacy). Contextual factors that contributed to benefits included the non-clinical setting, informality of meetings and reciprocal learning, and feeling valued by the program and students.
Health mentors perceive benefits in passing on their lived experiences to students, leading to personal growth and new activities. Their perspectives offer unique insights into the workings of effective mentorship relationships. There is much to be learned about how benefits of mentoring are linked to program design.

Healthcare professionals (HCPs) experience extreme hardships and challenges during the time of COVID-19, due to their professional roles. At the same time, HCPs may experience a feeling of importance as contributing members of the community, which could enhance their well-being alongside COVID-19-work-related stressors.
This cross-sectional study examined the relationship between HCPs' proximity to COVID-19 patients and role-specific fears of COVID-19 and sense of emotional, social and psychological well-being.
Participants (
= 1,378) included HCPs who treated COVID-19 patients (frontliners,
= 188), HCPs that did not work directly with COVID-19 patients (secondliners,
= 524), and a group of non-HCPs who served as the comparison group (
= 666). Participants completed the Depression and Anxiety Stress Scale-21; Fear of COVID-19 Scale; Fear of COVID-19 Familial Infection Scale; and the Mental Health Continuum Short-Form.
Results indicate that the comparison group reported higher levels of fear of COVID-19 compared to secondliners, while frontliners reported the highest levels of fear of infecting their families. Frontliners and secondliners HCPs reported significantly higher levels of social and psychological well-being compared to the non-HCP group.
This study indicates that there are role-specific mental health outcomes related to HCP's proximity to COVID-19 patients.

The current NSCLS therapies are associated with poor outcomes and need further improvement. CircRNAs were shown to regulate NSCLC progression. However, little is known re garding the functions and mechanisms of circ_0017639 in NSCLC, which requires further extensive studies. The circ_0017639 expression in NSCLC tissues and cell lines was evaluated via qRT-RCR. Moreover, using ectopic plasmid incorporation and shRNA assays, we analyzed the circ_0017639-mediated cellular proliferative, migratory and invasive processes in NSCLC cell lines, using CCK-8, EdU, and transwell assays. Furthermore, the core proteins (p-PI3K, PI3K, p-AKT, and AKT) levels of the PI3K/AKT signaling cascade were investigated via immunoblotting. Finally, we tested the functional role of circ_0017639 by examining its regulation of xenograft tumor growths in nude mice in vivo. Circ_0017639 expression was remarkably high in the NSCLC tissues and cell lines. The transfection experiments showed that circ_0017639 overexpression was able to promote proliferative, migratory, and invasive properties of NSCLC cells, while sh-circ_0017639 showed opposing effects. We further showed that circ_0017639 knockdown suppressed the cellular development via PI3K/AKT cascade inactivation. Additionally, in-vivo experiment in nude mice demonstrated that sh-circ_0017639 could reduce the tumor growth of NSCLC. Circ_0017639 may promote the development of NSCLC by accelerating NSCLC metastasis through stimulating the PI3K/AKT cascade.
This study aimed to investigate whether liposomal quercetin (LQ) could enhance the effects of microwave ablation (MVA) in treating the rabbit VX2 liver tumor model.
Rabbits with VX2 liver tumors were randomly divided into three groups intravenous LQ group (LQ group), MWA group and LQ combined with MWA (LQ + MWA) group. Five rabbits were randomly selected and sacrificed from each group at 12 h and on days 3, 7 and 14 of the operation. The tumor samples were detected and quantified by immunohistochemistry, Western blot, and reverse transcription polymerase chain reaction (RT-PCR).
For up to 7 days, the coagulation necrosis volume (CV) of the LQ + MWA group was larger than that of MWA and LQ groups (
< 0.05). Fourteen days after the operation, the total tumor volume of the LQ + MWA group was smaller than that of the LQ group and the MWA group (
< 0.05). The survival time of the LQ + MWA group was significantly longer than that of the MWA and LQ groups (
< 0.01). Heat shock protein 70 (HSP70) excessive proliferation of residual tumor and angiogenesis, and decrease metastasis and prolong the survival period of experimental animals.
