The Effect of Atorvastatin on Obsessive-compulsive Symptoms of Refractory Obsessive-compulsive Disorder (Add-on Therapy)

Advanced Biomedical Research, 2018
Background: Considering the effect of statins on the regulation of dopamine neurotransmitters and glutamates and importance of the treatment of obsessive-compulsive disorder (OCD) due to its relatively high prevalence and disability of available drugs in

A Multifunctional Nanodelivery System Modified by Fusion Peptides Acts as Teriparatide Carrier for Noise‐Induced Hearing Loss Therapy

Advanced Science, EarlyView.
The fusion peptide LR27‐modified thermosensitive nanodelivery system exhibits both hair cell targeting and inner ear penetrating properties. This system sustainably and effectively delivers PTH1‐34 to the inner ear of a hearing loss mouse model via the synergistic effects of multiple peptides, achieving satisfactory hearing protection through ...

α‐Synuclein Pathology Spreads in a Midbrain–Hindbrain Assembloid Model

Advanced Science, EarlyView.
A novel midbrain–hindbrain assembloid model demonstrates the spread of α‐synuclein pathology, a hallmark of Parkinson's disease, mimicking Braak's hypothesis. This model reveals how pathology propagates from the hindbrain to the midbrain, inducing synaptic changes and early signs of neuronal vulnerability. It offers an innovative platform for exploring

A Molecular Communication Perspective of Alzheimer's Disease: Impact of Amyloid Beta Oligomers on Glutamate Diffusion in the Synaptic Cleft [PDF]

arXiv
Molecular communication (MC) within the synaptic cleft is vital for neurotransmitter diffusion, a process critical to cognitive functions. In Alzheimer's Disease (AD), beta-amyloid oligomers (A$\beta$os) disrupt this communication, leading to synaptic dysfunction.

In‐Depth Cell‐Type‐Specific Proteome Landscape of the Brain from Human Amyloid‐β Overexpression Mouse Model

Advanced Science, EarlyView.
In situ Cell‐type‐specific proteome Analysis using antibody‐mediated Biotinylation (iCAB) is a method that directly targets and analyzes proteins in specific cell types within tissue. Applied to 5xFAD mice, iCAB identifies ≈8000 cell‐type‐specific proteins, revealing unique pathways in neurons, astrocytes, and microglia.

Impact of Co-Excipient Selection on Hydrophobic Polymer Folding: Insights for Optimal Formulation Design [PDF]

arXiv
The stabilization of liquid biological products is a complex task that depends on the chemical composition of both the active ingredient and any excipients in solution. Frequently, a large number of unique excipients are required to stabilize biologics, though it is not well-known how these excipients interact with one another. To probe these excipient-

Superoxide reductase from Desulfoarculus baarsii: reaction mechanism and role of glutamate 47 and lysine 48 in catalysis [PDF]

Biochemistry, American Chemical Society, 2001, pp.5032-40, 2015
Superoxide reductase (SOR) is a small metalloenzyme that catalyzes reduction of O(2)(*)(-) to H(2)O(2) and thus provides an antioxidant mechanism against superoxide radicals. Its active site contains an unusual mononuclear ferrous center, which is very efficient during electron transfer to O(2)(*)(-) [Lombard, M., Fontecave, M., Touati, D., and Nivi ...

Presbycusis: Pathology, Signal Pathways, and Therapeutic Strategy

Advanced Science, EarlyView.
In ARHL, the stria vascularis, acting as a cochlear battery, gradually loses its ability to maintain the endocochlear potential, leading to impaired hair cell function and progressive hearing loss. Single‐cell sequencing reveals age‐related cellular changes in the cochlea, providing insights into the underlying mechanisms of aging and potential ...

Gene Expression and Molecular Characterization of a Xylanase from Chicken Cecum Metagenome

International Journal of Microbiology, 2017
A xylanase gene xynAMG1 with a 1,116-bp open reading frame, encoding an endo-β-1,4-xylanase, was cloned from a chicken cecum metagenome. The translated XynAMG1 protein consisted of 372 amino acids including a putative signal peptide of 23 amino acids ...
