The prevalence of obesity is increasing globally, with approximately 700 million obese people worldwide. Currently, regulating energy homeostasis by increasing energy expenditure is attracting attention as a strategy for treating obesity. White adipose tissue is known to play a role in accumulating energy by storing excess energy, while brown adipose tissue expends energy and maintains body temperature.

Most of the currently available drugs are derived from natural sources, but they are used only after extensive chemical modifications to improve their safety and efficacy. Natural products are used in health supplements and cosmetic preparations and have been used as auxiliary drugs or alternative medicines. When used in combination with conventional drugs, these herbal products are known to alter their pharmacokinetics and pharmacodynamics, reducing their therapeutic effects.

Article Synopsis
  • Precision medicine is a personalized patient care approach, with pharmacogenomics studying how an individual's genes affect their drug responses, particularly for effective treatment with minimal side effects.* -
  • Rheumatoid arthritis (RA) is an autoimmune disease that leads to chronic joint inflammation, and studies show that genetic variations (SNPs) can influence how patients respond to monoclonal antibody therapies.* -
  • Current RA treatments often rely on trial and error, but pharmacogenomic strategies could enhance treatment decisions, improving quality of life and reducing costs for patients.*

calcium imaging is a standard neuroimaging technique that allows selective observation of target neuronal activities. In calcium imaging, neuron activation signals provide key information for the investigation of neural circuits. For efficient extraction of the calcium signals of neurons, selective detection of the region of interest (ROI) pixels corresponding to the active subcellular region of the target neuron is essential.

(commonly known as kokum), belonging to the Clusiaceae family (mangosteen family), is a tropical evergreen tree distributed in certain regions of India. It has been used in culinary and industrial applications for a variety of purposes, including acidulant in curries, pickles, health drinks, wine, and butter. In particular, has been used in traditional medicine to treat inflammation, dermatitis, and diarrhea, and to promote digestion.

Article Synopsis
  • - The study focuses on detecting Alzheimer's disease (AD) by examining a new neuromarker called the "refined network" in the prefrontal cortex (PFC), emphasizing its potential to reveal AD's pathological features.
  • - Researchers improved upon traditional methods by isolating the refined network from the working memory-related network, effectively removing irrelevant cognitive processes and individual differences that could obscure important data.
  • - Using functional near-infrared spectroscopy (fNIRS), the study found the refined network to have high reliability and significant correlations with cognitive function, achieving an impressive 95.0% accuracy in classifying individuals based on their AD progression stage.

Obesity is a lipid metabolism disorder caused by genetic, medicinal, nutritional, and other environmental factors. It is characterized by a complex condition of excess lipid accumulation in adipocytes. Adipogenesis is a differentiation process that converts preadipocytes into mature adipocytes and contributes to excessive fat deposition.

As a promising future treatment for stroke rehabilitation, researchers have developed direct brain stimulation to manipulate the neural excitability. However, there has been less interest in energy consumption and unexpected side effect caused by electrical stimulation to bring functional recovery for stroke rehabilitation. In this study, we propose an engineering approach with subthreshold electrical stimulation (STES) to bring functional recovery.

(Moraceae), known as white mulberry, has been used to treat fever, protect against liver damage, improve eyesight, and lower blood sugar levels in traditional oriental medicine. Few studies have been conducted on the antidiabetic compounds identified from and their underlying mechanisms of action. Consequently, in this study, the fruits of were investigated for potential antidiabetic natural products using 3T3-L1 adipocytes.

As a surrogate for human tactile cognition, an artificial tactile perception and cognition system are proposed to produce smooth/soft and rough tactile sensations by its user's tactile feeling; and named this system as "tactile avatar". A piezoelectric tactile sensor is developed to record dynamically various physical information such as pressure, temperature, hardness, sliding velocity, and surface topography. For artificial tactile cognition, the tactile feeling of humans to various tactile materials ranging from smooth/soft to rough are assessed and found variation among participants.

Oxidative stress is closely linked to various diseases, and many studies have been conducted to determine how to reduce this stress. In particular, efforts are being made to find potential antioxidants from natural products. Studies have shown that raspberry ketone (RK; 4-(4-hydroxyphenyl)-2-butanone) has various pharmacological activities.

In this study, the protective effects of white mulberry () fruits on lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages were investigated. The ethanol (EtOH) extract of white mulberry fruits and its derived fractions contained adequate total phenolic and flavonoid contents, with good in vitro antioxidant radical scavenging activity.

Article Synopsis
  • * The study investigated functional connectivity (FC) in the prefrontal cortex using a portable functional near-infrared spectroscopy (fNIRS) device during a working memory task, comparing healthy controls to those with CD.
  • * Results showed significantly greater prefrontal FC in the CD group, suggesting a compensatory mechanism in response to hippocampal degeneration, indicating that these FC differences could serve as biomarkers for early MCI detection.

Mulberry plants belonging to the Moraceae family have been grown for the purpose of being the nutrient source for silk worm and raw materials for the preparation of jams, marmalades, vinegars, juices, wines, and cosmetics. L. (black mulberry) is native to Southwestern Asia, and it has been used as a traditional herbal medicine for animals and humans.

Electroencephalograms (EEGs) measure a brain signal that contains abundant information about the human brain function and health. For this reason, recent clinical brain research and brain computer interface (BCI) studies use EEG signals in many applications. Due to the significant noise in EEG traces, signal processing to enhance the signal to noise power ratio (SNR) is necessary for EEG analysis, especially for non-invasive EEG.

Purpose: Single port laparoscopic surgery is a rapidly evolving laparoscopic surgical approach. We report a comparison of transumbilical single port laparoscopic appendectomy (TUSPLA) and conventional laparoscopic appendectomy (CLA) in a Korean military hospital.

Methods: This single-center retrospective study of 63 patients who received laparoscopic appendectomy was conducted between May 2011 and October 2011.

Eosinophilic peritonitis is defined as when there are more than 100 eosinophils present per milliliter of peritoneal effluent, of which eosinophils constitute more than 10% of its total WBC count. Most cases occur within the first 4 weeks of peritoneal catheter insertion and they usually have a benign and self-limited course. We report a patient of eosinophilic peritonitis that was successfully resolved without special treatment.
