Reproducible image-based profiling with Pycytominer.

Advances in high-throughput microscopy have enabled the rapid acquisition of large numbers of high-content microscopy images. Next, whether by deep learning or classical algorithms, image analysis pipelines commonly produce single-cell features. To process these single cells for downstream applications, we present Pycytominer, a user-friendly, open-source Python package that implements the bioinformatics steps key to image-based profiling.

ISR Modulators in Neurological Diseases.

The dysfunction of different cells lies in the pathogenesis of neurological diseases and is usually associated with cellular stress. Various stressors trigger the integrated stress response (ISR) signaling, whose highly conserved mechanism is primarily aimed at protecting a stress-exposed cell to cope as safely as possible with such stressful conditions. On the contrary, if a cell is unable to cope with excessive stress, the ISR can induce apoptosis.

Different threshold responses in spontaneously changing postagrogenic forest and unmanaged grassland. Shifts in small mammal populations and communities triggered by an extraordinary drought.

Due to their resilience, various biological systems under environmental changes typically exhibit nonlinear responses with sudden, abrupt shifts. Although such shifts are theoretically expected, few studies traced state-and-transition dynamics in nature (Liu et al., Science 317:1513-1516, 2007).

Cardiorespiratory-gated cardiac proton radiotherapy using a novel ultrasound guidance system.

Cardiac stereotactic body radiotherapy is a promising noninvasive treatment for patients with refractory ventricular tachycardia. With the aim to prove feasibility of a novel image guided radiotherapy and heart motion gating device, cardiac proton radiotherapy was performed using a porcine model. Using a novel adaptation of γ - H2AX tissue staining techniques, we have been able to localize a radiation beam in large animal tissue to assess targeting accuracy within a defined field.

Lumbar total disk replacement versus microsurgical lumbar discectomy in treatment of radicular and back pain in railway workers: a prospective randomized controlled trial.

Background: Currently, there remains a high percentage of complications after lumbar discectomy, while there is no uniform tactic to prevent their development. Purpose of the study was to compare the clinical efficacy and return to work rate (RWR) after total disk replacement (TDR) and microsurgical lumbar discectomy (MLD) in railway workers with lumbar disk herniation (LDH).

Methods: We randomly assigned 75 patients out of a total of 81 patients, between 25 and 35 years of age who had one level LDH to undergo single-level TDR surgery (group I, n=37) or MLD surgery (group II, n=38) in the L4-L5 or L5-S1 segments.
