This stabilizing property of the MIA40 C-terminal region could also be conferred to a different mitochondrial precursor protein, COX19.

Our data suggest that the MIA40 precursor contains the stabilizing information to allow for postranslational import of sufficient amounts of MIA40 for full functionality of the essential disulfide relay. We thereby provide for the first time mechanistic insights into the determinants controlling cytosolic surveillance of IMS precursor proteins.

Named for their capability of killing target cells autonomously, natural killer (NK) cells serve as the main effector cells toward cancer in innate immunity and are highly heterogeneous in the microenvironment. Most current treatment options harnessing the tumor microenvironment focus on T cell-immunity, either by promoting activating signals or suppressing inhibitory ones. The limited success achieved by T cell immunotherapy highlights the importance of developing new-generation immunotherapeutics, for example utilizing previously ignored NK cells. Although tumors also evolve to resist NK cell-induced cytotoxicity, cytokine supplement, blockade of suppressive molecules and genetic engineering of NK cells may overcome such resistance with great promise in both solid and hematological malignancies. In this review, we summarized the fundamental characteristics and recent advances of NK cells within tumor immunometabolic microenvironment, and discussed potential application and limitations of emerging NK cell-based therapeutic strategies in the era of presicion medicine.

Pseudomonas aeruginosa is a Gram-negative pathogen that frequently causes life-threatening infections in immunocompromised patients. We previously showed that subinhibitory concentrations of short synthetic peptides permeabilize P. aeruginosa and enhance the lethal action of co-administered antibiotics.

Long-term permeabilization caused by exposure of multidrug-resistant P. aeruginosa strains to peptide P4-9 was investigated by measuring the uptake of several antibiotics and fluorescent probes and by using confocal imaging and atomic force microscopy.

We demonstrated that P4-9, a 13-amino acid peptide, induces a growth delay (i.e. post-antibiotic effect) of 1.3 h on a multidrug-resistant P. aeruginosa clinical isolate. Remarkably, when an independently P4-9-treated culture was allowed to grow in the absence of the peptide, cells remained sensitive to subinhibitory concentrations of antibiotics such as ceftazidime, fosfomycin and erythromycin for at least 2 h. We designated this persistent sensitization ert its antibiotic enhancing activity as long as the target organism retains sensitization to the antibiotic.

The phenomenon of long-term sensitization to antibiotics shown here may have important therapeutic implications for a combined peptide-antibiotic treatment because the peptide would not need to be present to exert its antibiotic enhancing activity as long as the target organism retains sensitization to the antibiotic.

In 2019, the Constitutional Court of South Korea ruled that the anti-abortion provisions in the Criminal Act, which criminalize abortion, do not conform to the Constitution. This decision will lead to a total reversal of doctors’ legal duty from the obligation to refuse abortion services to their requirement to provide them, given the Medical Service Act that states that a doctor may not refuse a request for treatment or assistance in childbirth. I argue, confined to abortion services in Korea that will take place in the near future, that doctors should be granted the legal right to exercise conscientious objection to abortion.

Considering that doctors in Korea have been ethically and legally obligated to refrain from abortions for many years, imposing a universal legal duty to provide abortions that does not allow exception may endanger the moral integrity of individual doctors who chose a career when abortion was illegal. The universal imposition of such a duty may result in repudiation of doctors as mod be granted the legal right to exercise conscientious objection based on the importance of doctor’s moral integrity, lack of impediment to patients, and government responsibility.

With regard to abortion services that will be sought in the near future, doctors should be granted the legal right to exercise conscientious objection based on the importance of doctor’s moral integrity, lack of impediment to patients, and government responsibility.

Evidence-based medicine (EBM) is a core competence in both undergraduate and postgraduate medical curricula. However, its integration into curricula varies widely. Our study will help medical colleges develop, implement and evaluate their EBM courses. We assessed the effectiveness of workshops in improving critical appraisal skills among medical students.

A before-and-after study design without a control group was used. A 5-week short EBM module including lectures, workshops, and online search sessions was conducted with 52 fourth-year medical students during their primary healthcare course at the College of Medicine, Princess Nourah bint Abdulrahman University. Statistical analysis was performed using SPSS statistical software (version 20, SPSS Inc., Chicago, US). Parametric tests as well as Student’s paired t-test for pre- and post-test comparisons were used.

Forty-nine (49) participants completed the pre- and post-training Fresno tests, and 44.9% of the participants had a GPA of 4.0 or higher. The me and skills in EBM. However, prospective studies are necessary to assess the long-term impact of these interventions and ultimately their effectiveness for clinical decision making.
