Pre-folding purification procedures for inclusion body-derived non-tagged cationic recombinant proteins with multiple disulfide bonds for efficient refolding.

The production of disulfide-containing recombinant proteins often requires refolding of inclusion bodies before purification. A pre-refolding purification step is crucial for effective refolding because impurities in the inclusion bodies interfere with refolding and subsequent purification. This study presents a new pre-refolding procedure using a reversible S-cationization technique for protein solubilization and purification by reversed-phase high performance liquid chromatography.

Mapping Surface Potential in DNA Aptamer-Neurochemical and Membrane-Ion Interactions on the SOS Substrate Using Terahertz Microscopy.

In this study, we utilized a terahertz chemical microscope (TCM) to map surface potential changes induced by molecular interactions on silicon-on-sapphire (SOS) substrates. By functionalizing the SOS substrate with DNA aptamers and an ion-selective membrane, we successfully detected and visualized aptamer-neurochemical complexes through the terahertz amplitude. Additionally, comparative studies of DNA aptamers in PBS buffer and artificial cerebrospinal fluid (aCSF) were performed by computational structure modeling and terahertz measurements.

The Impact of Task Context on Pleasantness and Softness Estimations: A Study Based on Three Touch Strategies.

This study investigated the two distinct perceptions (pleasantness and softness) of deformable stimuli with different degrees of compliance under conditions with and without a contextual task. Three tactile strategies-grasping, pinching, and pressing-were used to perceive the stimuli. In Experiment 1 (without a contextual task), participants estimated the perceived intensity of softness or pleasantness for each stimulus.

Beyond Facilitating Unisensory Processing: Crossmodal Associative Memory Training Further Modulates Sensory Integration.

Audiovisual associative memory and audiovisual integration involve common behavioral processing components and significantly overlap in their neural mechanisms. This suggests that training on audiovisual associative memory may have the potential to improve audiovisual integration. The current study tested this hypothesis by applying a 2 (group: audiovisual training group, unimodal control group) * 2 (time: pretest, posttest) design.

PTPA localized in the Golgi apparatus plays an important role in osteoblast differentiation.

Regulatory subunits of protein phosphatase 2A (PP2A) define the substrate and functional specificity of the PP2A holoenzyme within specific organelles. While PP2A regulates osteoblast differentiation, the roles and localization of its regulatory subunits in osteoblasts remain unclear. Here, we identified PTPA, a PP2A regulatory protein, predominantly localized to the Golgi apparatus, closely overlapping with the Golgi marker Giantin.

The role of sleep quality in mediating the relationship between habenula volume and resilience.

Background: Our human volumetric MRI study (Dai et al., 2024) demonstrated that habenula (Hb) volume is associated with psychological resilience, a key protective factor against depression. However, the biological mechanisms underpinning this relationship remain unclear.

Novel Drug Delivery Particles Can Provide Dual Effects on Cancer "Theranostics" in Boron Neutron Capture Therapy.

Boron (B) neutron capture therapy (BNCT) is a novel non-invasive targeted cancer therapy based on the nuclear capture reaction B (n, alpha) Li that enables the death of cancer cells without damaging neighboring normal cells. However, the development of clinically approved boron drugs remains challenging. We have previously reported on self-forming nanoparticles for drug delivery consisting of a biodegradable polymer, namely, "AB-type" Lactosome nanoparticles (AB-Lac particles)- highly loaded with hydrophobic B compounds, namely -Carborane (Carb) or 1,2-dihexyl--Carborane (diC6-Carb), and the latter (diC6-Carb) especially showed the "molecular glue" effect.

Eyelid Spindle Cell Lipoma: Case Report and Review of Three Patients in Literature.

A 39-year-old woman presented a saucer-shaped mass in the left upper eyelid and underwent the extirpation at local anesthesia. Pathologically, collagen fibers, capillaries, small vessels, and CD34-positive spindle cells were dispersed among mature adipose tissues, indicative of spindle cell lipoma. Long-lasting cyst-like eyelid masses would be usually dermoid cysts, and spindle cell lipoma would be listed as a rare pathological diagnosis in differential diagnoses of cyst-like lesions in the upper and lower eyelid.

Contributions of the Primary Sensorimotor Cortex and Posterior Parietal Cortex to Motor Learning and Transfer.

Background: Transferring learned manipulations to new manipulation tasks has enabled humans to realize thousands of dexterous object manipulations in daily life. Two-digit grasp and three-digit grasp manipulations require different fingertip forces, and our brain can switch grasp types to ensure good performance according to motor memory. We hypothesized that several brain areas contribute to the execution of the new type of motor according to the motor memory.

Long-term exercise training reduced the sound-induced flash illusion in multisensory illusions owing to the cerebellum.

Sound-induced flash illusion (SiFI) is an auditory-dominant multisensory illusion that can be used to assess multisensory integration. Although previous studies have shown that one-time intervention exercise training does not significantly affect SiFI, the long-term improvement of SiFI with exercise training remains controversial. In the present study, the classical SiFI paradigm was used to investigate the effects of long-term exercise training on the SiFI.

Medicinal plants have been proven rich in thousands of natural products that hold great potential for the development of new drugs. Previously, we reviewed the types of Chinese traditional medicines that a Tang Dynasty monk Jianzhen (Japanese: Ganjin) brought to Japan from China in 742.

Efficient single-channel current measurements of the human BK channel using a liposome-immobilized gold probe.

The human BK channel (hBK) is an essential membrane protein that regulates various biological functions, and its dysfunction leads to serious diseases. Understanding the biophysical properties of hBK channels is crucial for drug development. Artificial lipid bilayer recording is used to measure biophysical properties at the single-channel level.

Cue modality modulates interaction between exogenous spatial attention and audiovisual integration.

Exogenous spatial attention attenuates audiovisual integration (AVI). Previous studies on the effects of exogenous spatial attention on AVI have focused on the inhibition of return (IOR) effect induced by visual cues and the facilitation effect induced by auditory cues, but the differences between the effects of exogenous spatial attention (induced by visual and auditory cues) on AVI remain unclear. The present study used the exogenous spatial cue-target paradigm and manipulated cue stimulus modality (visual cue, auditory cue) in two experiments (Experiment 1: facilitation effect; Experiment 2: IOR effect) to examine the effects of exogenous spatial attention (evoked by cues in different modalities) on AVI.
