The perceived stress and anxiety among medical students have bleak consequences on their academic performances, physical, and psychological wellbeing. However, there is a dearth of reliable epidemiological studies in Ethiopia on medical student's experience of stress and anxiety. Therefore, this study was aimed to determine the prevalence and identify factors associated with stress and anxiety among undergraduate medical students of Haramaya University, Eastern Ethiopia. An institutional-based cross-sectional study was conducted from May 13 to June 12, 2019 among 523 participants selected by simple random sampling technique. Data were collected by using structured questionarie through self-adminstered method. Data were entered by Epidata version 3.1 and analyzed using Stastical Package for Social Science(SPSS) version 22. Bivariableand multivariable logistic regression analysis were conducted to identify factors associated with anxiety and stress. Adjusted Odd Ratio (AOR) and 95% Confidence Interval(CI) w living off-campus were linked with both stress and anxiety. Where as, alcohol use and smoking cigarette were associated with stress and poor psychological support was significantly associated with anxiety.The newly emerged ribonucleic acid (RNA) enveloped human beta-coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection caused the COVID-19 pandemic, severely affects the respiratory system, and may lead to death. Lacking effective diagnostics and therapies made this pandemic challenging to manage since the SARS-CoV-2 transmits via human-to-human, enters via ACE2 and TMPSSR2 receptors, and damages organs rich in host cells, spreads via symptomatic carriers and is prominent in an immune-compromised population. New SARS-CoV-2 informatics (structure, strains, like-cycles, functional sites) motivated bio-pharma experts to investigate novel therapeutic agents that act to recognize, inhibit, and knockdown combinations of drugs, vaccines, and antibodies, have been optimized to manage COVID-19. However, successful targeted delivery of these agents to avoid off-targeting and unnecessary drug ingestion is very challenging. To overcome these obstacles, this mini-review projects nanomedicine tecd cellular immune responses. The desired and controlled features of suggested personalized therapeutics, nanomedicine, is a potential therapy to manage COVID-19 successfully. The state-of-the-art nanomedicine, challenges, and prospects of nanomedicine are carefully and critically discussed in this report, which may serve as a key platform for scholars to investigate the role of nanomedicine for higher efficacy to manage the COVID-19 pandemic. Several studies have demonstrated various molecular mechanisms involved in the biogenesis and release of exosomes. However, how external stimuli, such as platinum nanoparticles (PtNPs), induces the biogenesis and release of exosomes remains unclear. To address this, PtNPs were synthesized using lutein to examine their effect on the biogenesis and release of exosomes in human lung epithelial adenocarcinoma cancer cells (A549). The size and concentration of isolated exosomes were characterized by dynamic light scattering (DLS) and nanoparticle tracking analysis system (NTA). Morphology and structure of exosomes were examined using scanning electron microscopy and transmission electron microscopy (TEM), respectively. Quantification of exosomes were analyzed by EXOCET assay and fluorescence polarization (FP). The expression of typical markers of exosomes were analyzed by quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and enzyme-linked immunosorbent assay (ELISA). A549 cells culturecancer. Importantly, this is the first study, to our knowledge, showing that PtNPs stimulate exosome biogenesis by inducing oxidative stress and the ceramide pathway. PtNPs provide a promising agent to increase exosome production in A549 cells. These findings offer novel strategies for enhancing exosome release, which can be applied in the treatment and prevention of cancer. Importantly, this is the first study, to our knowledge, showing that PtNPs stimulate exosome biogenesis by inducing oxidative stress and the ceramide pathway.Nanotechnology has prompted the development of hollow inorganic nanomedicine. https://www.selleckchem.com/products/uk5099.html These medicines are now widely investigated as photothermal-based therapies for various diseases due to their high loading capacity, tuneable wavelength, relatively small size and low density. We begin this review with a brief introduction, followed by a summary of the development of imaging-guided photothermal therapy (PTT) for cancer treatment during the last three years (from 2017 to 2020). We then introduce the antibacterial effects of these medicines on some bacterial infections, in which the pathogenic bacteria can be killed by mild photothermal effects, ions and antibiotic release. Other diseases can also be treated using hollow inorganic photothermal agents. Specifically, we discuss the use of PTT for treating Alzheimer's disease, obesity and endometriosis. Finally, we share our perspectives on the current challenges and future prospects of using hollow inorganic materials in clinical PTT for various diseases. Acute care of patients with exacerbation of chronic obstructive pulmonary disease (AECOPD) in the emergency department (ED) is crucial, however not studied extensively in Nepal. The purpose of this study is to identify the opportunities for succinct measures to optimize the AECOPD care in ED with a multifaceted bundle care approach in a resource-limited setting. We conducted a prospective cross-sectional observational study as an initial baseline stage of the quality improvement project. Demographic data, clinical characteristics, the current diagnosis and treatment performances of AECOPD were recorded. The primary outcome measures were 30-day ED revisit and near-fatal events which were compared with other variables and performances with binary and logistic regression. The multidisciplinary team performed the root cause and Pareto analysis to identify the potential gaps in the AECOPD care. The AECOPD performance measures were suboptimal. Written AECOPD emergency management clinical guidelines and advice regarding pulmonary rehabilitation were absent.
