Exploring the frontiers of metal additive manufacturing in orthopaedic implant development.

This paper provides a thorough analysis of recent advancements and emerging trends in the integration of metal additive manufacturing (AM) within orthopedic implant development. With an emphasis on the use of various metals and alloys, including titanium, cobalt-chromium, and nickel-titanium, the review looks at their characteristics and how they relate to the creation of various orthopedic implants, such as spinal implants, hip and knee replacements, and cranial-facial reconstructions. The study highlights how metal additive manufacturing (AM) can revolutionize the field by enabling customized implant designs that take patient anatomical variances into account.

The Intricate Interplay: Microbial Metabolites and the Gut-Liver-Brain Axis in Parkinson's Disease.

Parkinson's Disease (PD) is a neurodegenerative disorder marked by the depletion of dopaminergic neurons. Recent studies highlight the gut-liver-brain (GLB) axis and its role in PD pathogenesis. The GLB axis forms a dynamic network facilitating bidirectional communication between the gastrointestinal tract, liver, and central nervous system.

Compartmentalizing Donor-Acceptor Stenhouse Adducts for Structure-Property Relationship Analysis.

The development of photoswitches that absorb low energy light is of notable interest due to the growing demand for smart materials and therapeutics necessitating benign stimuli. Donor-acceptor Stenhouse adducts (DASAs) are molecular photoswitches that respond to light in the visible to near-infrared spectrum. As a result of their modular assembly, DASAs can be modified at the donor, acceptor, triene, and backbone heteroatom molecular compartments for the tuning of optical and photoswitching properties.

Inversion for water column sound speed profile from acoustic travel times using empirical orthogonal functions.

An acoustic propagation experiment was conducted in the western continental shelf of India (off Kollam, Kerala) in water depth of ∼71 m with seafloor consisting of hard sandy sediments. The multipath arrival times are obtained from peaks in acoustic impulse response measurements made on a single hydrophone for two source-receiver ranges of 245 m and 320 m. The arrival times are used for inverting the water column sound speed profile (SSP) utilizing the empirical orthogonal functions (EOFs), which can completely describe large datasets.
