Frontotemporal dementia (FTD) is the second leading cause of early onset dementia following Alzheimer's disease. It involves atrophy of the frontal and temporal regions of the brain affecting language, memory, and behavior. Transactive response DNA-binding protein 43 (TDP-43) pathology is found in most FTD and ALS cases. It plays a role in transcription, translation and serves as a shuttle between the nucleus and cytoplasm. Prior to its aggregation, TDP-43 exists as polyubiquitinated, hyperphosphorylated C-terminal fragments that correlate well with FTD disease progression. Because of the importance of TDP-43 in these diseases, reagents that can selectively recognize specific toxic TDP variants associated with onset and progression of FTD can be effective diagnostic and therapeutic tools.

We utilized a novel atomic force microscopy (AFM) based biopanning protocol to isolate single chain variable fragments (scFvs) from a phage display library that selectively bind TDP variants present in human FTD but not g these disease specific TDP variants in postmortem FTD tissue and sera samples over age matched controls and can thus serve as a biomarker tool.

Neurons are the basic structural unit of the brain, and their morphology is a key determinant of their classification. The morphology of a neuronal circuit is a fundamental component in neuron modeling. Recently, single-neuron morphologies of the whole brain have been used in many studies. The correctness and completeness of semimanually traced neuronal morphology are credible. However, there are some inaccuracies in semimanual tracing results. The distance between consecutive nodes marked by humans is very long, spanning multiple voxels. On the other hand, the nodes are marked around the centerline of the neuronal fiber, not on the centerline. Although these inaccuracies do not seriously affect the projection patterns that these studies focus on, they reduce the accuracy of the traced neuronal skeletons. These small inaccuracies will introduce deviations into subsequent studies that are based on neuronal morphology files.

We propose a neuronal digital skeleton optimization method to evaluate and make finl skeletons that are acquired, the more precise the neuronal morphologies that are analyzed will be.

This method can improve the accuracy of a neuronal digital skeleton based on traced results. The greater the accuracy of the digital skeletons that are acquired, the more precise the neuronal morphologies that are analyzed will be.

The current study aimed to investigate the potential of solid self-emulsifying drug delivery systems (solid SEDDS) loaded with testosterone undecanoate (TU) (solid TU-SEDDS). The solid TU-SEDDS was composed of TU, medium-chain triglycerides (MCT, oil), 2-Chloro-1-(chloromethyl) ethyl carbamate (EL-35, surfactant) and polyethylene glycol (PEG400, cosurfactant). It was expected to improve the dissolution and oral bioavailability of TU, as a result of investigating the feasibility of clinical application of SEDDS.

First, a TU-SEDDS was developed by using rational blends of components with good solubilizing ability for TU. Next, a ternary phase diagram was constructed to determine the self-emulsifying region, and the formulation was optimized. Then, the solid TU-SEDDS formulation was established by screening suitable solid adsorptions. Finally, the prepared SEDDS, TU-SEDDS and solid TU-SEDDS formulations were evaluated in vitro and in vivo.

The size of the solid TU-SEDDS was 189.1 ± 0.23 nm. The transmissioaps® (37.17±13.79 µg/L×h, P > 0.05).

According to the results of this research, oral solid TU-SEDDS is expected to be another alternative delivery system for the late-onset hypogonadism. This is beneficial to the transformation of existing drug delivery systems into preclinical and clinical studies.

Celecoxib is a non-steroidal anti-inflammatory drug (NSAID) and cyclooxygenase-2 (COX-2) inhibitor. It is used for the treatment of rheumatoid arthritis, osteoarthritis, juvenile arthritis, and acute pain. Celecoxib has low systemic bioavailability due to its low water solubility. This study aimed to improve water solubility and dissolution profile by synthesizing a suitable celecoxib potassium salt (celecoxib-K salt).

Four celecoxib salts were synthesized, and the solubility of these four salts was determined. Celecoxib-K monohydrate salt was chosen for tablet formulation. A simple and feasible reversed-phase high-performance liquid chromatography (HPLC) method was developed for the analysis of the formulated tablet and then validated according to international guidelines. The dissolution profile, shelf life, and accelerated stability studies on the formulated tablet were conducted.

Celecoxib-K monohydrate salt exhibited increased water solubility by more than 140-folds (0.464 mg/ml) compared with celeethod was valid and reliable for analysis and quantification of the formulated tablet. The formulated tablet was stable both at room temperature and under stress conditions.

Unlike papillary thyroid cancer (PTC), anaplastic thyroid carcinoma (ATC) is extremely aggressive and rapidly lethal without effective therapies. However, the differences of master regulators and regulatory networks between PTC and ATC remain unclear.

Three representative datasets comprising 32 ATC, 69 PTC, and 78 normal thyroid tissue samples were combined to form a large dataset. SY-5609 in vivo Differentially expressed genes (DEGs) were identified and enriched by limma package and gene set enrichment analysis, respectively. Subsequently, protein-protein interaction network and transcription factors (TFs) regulatory network were constructed to identify gene modules and master regulators. Further, master regulators were validated by RT-PCR and western blot. Finally, Kaplan-Meier plotter was applied to evaluate their prognostic values.

A total of 560 DEGs were identified as ATC-specific malignant signature. The regulatory network analysis showed that nine master regulators were significantly correlated with three gene modules and potentially regulated the expression of DEGs in three gene modules, respectively.
