The subway is one of the most efficient transportation modes for mobility handicapped individuals regarding cost, time, and accessibility, especially when getting around the city.

Key Points:

The subway is one of the most efficient transportation modes for mobility handicapped individuals regarding cost, time, and accessibility, especially when getting around the city.
Unfortunately, each subway station has different characteristics, in terms of its area, the number of mobility handicapped users, the available facilities, and so on.
After that, they used the data envelopment analysis model to estimate the equity score of the subway stations.
The study also found that commercial and business districts of the city were the ones with the subway stations with lower scores, while residential areas had high-scoring subway stations.

SEOUL, South Korea, Jan. 18, 2024 /PRNewswire/ -- Plantar fasciitis (PF) is a common musculoskeletal, inflammatory condition, characterized by severe pain in the heel of the foot, to the extent that it limits day-to-day activities. The plantar fascia ligament, a fibrous connecting tissue, supports the arch of the foot and functions as a shock absorber, similar to modern-day car suspension systems. With increased activity, the ligament can experience tears and damage, leading to the development of PF.

Key Points:

Treatment for PF includes pain management through anti-inflammatory drugs, stretching exercises, night-splint therapy, steroidal medications, and extracorporeal shock wave therapy (ESWT).
Interestingly, their study revealed the combination of local vibration and extra-corporeal shock therapy as an effective approach for treating chronic plantar fasciitis.
One group received a combination of local vibration (LV) and ESWT, while the other group underwent ESWT alone.

SEOUL, South Korea, Jan. 16, 2024 /PRNewswire/ -- Memristive devices constitute a category of devices capable of retaining their internal resistance, thus offering superior performance compared to conventional devices that use integrated circuits.

Key Points:

SEOUL, South Korea, Jan. 16, 2024 /PRNewswire/ -- Memristive devices constitute a category of devices capable of retaining their internal resistance, thus offering superior performance compared to conventional devices that use integrated circuits.
Due to their increasing application in diverse domains like artificial intelligence systems, memristive devices must now overcome several issues related to data retention, endurance, and a large number of conductance states.
In a recent study led by Professor Min Kyu Yang from Sahmyook University, Korea, researchers have developed a silver (Ag)-dispersive chalcogenide thin film for use as a resistance-switching material in memristive devices.
This study thus emphasizes the capability of chalcogenide materials to enhance the performance of memristive devices.

Per2 is associated with our circadian rhythms, our internal clock which regulates our sleep-wake cycle.

Key Points:

Per2 is associated with our circadian rhythms, our internal clock which regulates our sleep-wake cycle.
However, its addictive responses to METH and other psychostimulant drugs like cocaine have not been examined as yet.
The researchers first investigated the motivational effect of these drugs and their impact on the locomotor activity of the mice using specialized tests.
Using existing data, the researchers could correlate these genes with those that are activated in the region of the brain that responds to drug addiction.

Brain lesions caused by the aggregation of amyloid β (Aβ) and neurofibrillary tangles are believed to be the main cause of AD.

Key Points:

Brain lesions caused by the aggregation of amyloid β (Aβ) and neurofibrillary tangles are believed to be the main cause of AD.
While many drugs targeting Aβ have been developed, they have failed to demonstrate efficacy in clinical trial studies.
Moreover, the use of approved antibody drugs is associated with high costs of treatment and uncertain efficacy.
Therefore, developing a simple and efficient drug that targets Aβ for the treatment of AD is needed.

Sahmyook University Study Repurposes Meclofenamate to Treat Abnormal Respiratory Mucus

Retrieved on:

Wednesday, July 26, 2023

SEOUL, South Korea, July 26, 2023 /PRNewswire/ -- Our respiratory system is lined with a thin fluid layer called mucus on the inside. The mucus protects us from inhaling harmful and unwanted airborne agents from germs to pollutants; it achieves this feat due to its unique gel-like texture imparted by proteins called mucins. By extension, over- or under-secretion of mucins can lead to abnormal respiratory mucus—a pathological manifestation in many respiratory diseases like chronic bronchitis, cystic fibrosis, and asthma, among others. Although multiple clinically approved drugs are available that can combat abnormal respiratory mucus, many of them cause unwanted and potentially serious side effects. This calls for an alternative solution to provide relief to patients having respiratory diseases.

Key Points:

Although multiple clinically approved drugs are available that can combat abnormal respiratory mucus, many of them cause unwanted and potentially serious side effects.
In a recent study, a group of researchers from Korea repurposed an available drug called meclofenamate to understand its effects on the respiratory mucus.
The researchers have now found that meclofenamate can also treat abnormal respiratory mucus by controlling mucin secretion.
Without doubt, meclofenamate has emerged as a novel therapeutic agent for abnormal respiratory mucus, with this study.
