Summary: In this paper, the authors relax the equality constraints of diffeomorphic image registration from Han and Wang (2020) [9] to include inequality constraints. Additionally, the issue of mesh folding is addressed, and a numerical algorithm for the proposed model is introduced. Numerical tests demonstrate the competitiveness of the proposed algorithm compared to other published image registration models.

Summary: The study found a high prevalence of latent tuberculosis infection (LTBI) among myasthenia gravis (MG) patients, especially among older age groups and males. However, receiving immunosuppressive therapies does not seem to increase the risk of LTBI reactivation. Screening for LTBI is strongly recommended for all MG patients ready to receive treatment, and preventive anti-tuberculosis chemotherapy should be prescribed after considering the potential benefits and risks in LTBI patients.

Summary: Screening for latent tuberculosis (TB) infection is important before initiating anti-tumor necrosis factor (anti-TNF) alpha agents to prevent TB reactivation. However, reactivation of latent TB infection can still occur, and the ideal therapeutic strategy for inflammatory bowel disease (IBD) patients who develop active TB infection has not been established. Vedolizumab (VDZ) has a good safety profile, but its safety in patients with latent TB infection reactivation associated with anti-TNF-alpha agents is unclear.

Summary: This study systematically reviewed literature from 2010 to 2020 and found 14 studies exploring the relationship between MS and LTBI. While reactivation of LTBI is well understood, literature addressing the association between the contagious disease and MS treatment is scarce.

Summary: In this paper, a novel training-free approach based on ordinary differential equations is proposed for diffeomorphic deformable image registration. The approach employs an Euler integration type recursive scheme to estimate spatial transformations between fixed and moving images at different resolutions. Unlike learning-based methods, this approach does not require a dedicated training set and is not affected by training bias.

Summary: This study compared the effects of MTB ag85ab and 7 latent DNA vaccines on clearing and preventing activation of latent MTB in a mouse model of latent tuberculosis infection (LTBI). The results showed that all vaccine groups significantly reduced the bacterial count and lesion degree in the lungs of mice, and induced antigen-specific cellular immune responses. Among them, MTB ag85ab and rv2659c, rv1733c DNA vaccines showed the most significant preventive effect.

Summary: Long-acting injectable bedaquiline has significant potential in shortening tuberculosis preventive therapy, with an injection of 160 mg/kg exerting antituberculosis activity for 12 weeks. Compared to oral regimens, the long-acting bedaquiline regimen showed superior sterilizing activity, indicating its effectiveness in preventing tuberculosis.

Summary: Image registration, an important technique in brain imaging analysis, aims to align two images through a spatial transformation. This research proposes a symmetric diffeomorphic image registration model based on multi-label segmentation masks. By introducing a new similarity metric and adaptive parameters, the proposed model improves accuracy, robustness, and smoothness of the registration compared to mainstream methods.

Summary: Retinotopic maps, which are important in vision science, are limited by the signal-to-noise ratio and spatial resolution of fMRI. We developed a new registration method called Diffeomorphic Registration for Retinotopic Maps (DRRM) to improve the quality of retinotopic maps by aligning them under the diffeomorphic condition. DRRM outperforms existing methods in achieving diffeomorphic registration in both synthetic and real datasets, and it may have applications in clinical settings.

Summary: Genetic mutants have demonstrated the importance of homologous recombination (HR) to fluoroquinolone (FQ) persistence, suggesting that different types of persister subtypes exist, with some proficient in HR. Furthermore, time-lapse microscopy revealed distinct growth dynamics during the post-antibiotic recovery period for persisters from monoploid-enriched and diploid-enriched subpopulations.

Summary: FLASH is a fast, luminescent, and affordable sensor developed for detecting and monitoring drug susceptibility of Mycobacterium tuberculosis (Mtb). It is selective for the Mtb protease Hip1 and can detect low amounts of Mtb cells with high sensitivity within minutes. FLASH can distinguish live from dead cells and has the potential to enhance TB diagnostics and drug resistance monitoring in resource-limited settings.

Summary: This study introduces a representation of multi-omics profiles to account for heterogeneity of DNA and RNA molecular profiles in cancer cells, and uses integer programming to identify a small set of paired DNA-RNA aberrations in cancer populations, resulting in the discovery of novel molecular alterations signatures. The results suggest that cancer heterogeneity increases with disease severity. This framework is well-suited for the expanding complexity of cancer genomes and epigenomes.

Summary: This paper examines a model for the longitudinal shape evolution, where a three-dimensional volume evolves through the time-derivative of an internal force and includes a regularization to ensure reversible transformations. The existence and uniqueness of solutions are discussed for two different models, and sufficient conditions for the optimal response are derived. This study is important for understanding the growth and atrophy processes in anatomical structures.

Summary: Despite advances in TB drug development, multidrug resistance remains a major challenge for global TB control. Host-directed therapies, such as inhibition of the integrated stress response (ISR), have the potential to improve the efficacy of tuberculosis antibiotics. In this study, we evaluated the impact of ISR inhibition on bacterial clearance, relapse, and lung pathology in a mouse model of TB. Our findings suggest that adjunctive ISR inhibition can accelerate bacterial clearance, reduce relapse rates, and improve lung health.

Summary: Histone deacetylase inhibitors (HDACis) modify chromatin compaction by affecting histone acetylation, targeting the epigenetic state of cells. Glioma cells with isocitrate dehydrogenase (IDH) 1 or 2 mutation exhibit changes in their epigenetic state and increased sensitivity to HDACis. Glioma cells expressing mutant IDH1 displayed stronger growth inhibition and apoptosis induction when treated with the HDACi drug belinostat. A phase I trial further showed that glioblastoma patients with mutant IDH1 tumor showed greater sensitivity to belinostat compared to wild-type IDH tumors. IDH mutation status may serve as a biomarker of response to HDACis.
