Background: Chuna manual therapy (CMT), a Korean manual therapy technique predominantly used for treating low back pain (LBP) and related disorders, lacks well-conceived research focusing on its comparative effectiveness, safety, and economic evaluation, particularly with respect to complex CMT with established CMT diagnostic algorithms. This study aims to illustrate a protocol for a randomized clinical study for comparative effectiveness and cost-effectiveness of complex CMT with simple CMT and usual care.

Methods: This is a protocol for a three-armed, multicenter, assessor-blinded, pragmatic, randomized controlled trial study.

Article Synopsis
  • * A study was conducted on pigs to evaluate the potential risks of using L-tryptophan as a feed additive, focusing on general toxicity and EMS-related symptoms.
  • * Results showed no toxic effects or EMS symptoms in the pigs, indicating that L-tryptophan and its impurities do not pose safety concerns, allowing its continued use in swine diets throughout all growth stages.

Ultrasound-guidance is applied during the administration of Korean medicine (KM) interventions to improve the safety and effectiveness of the interventions. Although many case series and reports on the use of ultrasound-guided KM interventions have been reported, no study has investigated the current use of ultrasound-guidance in clinical practice by doctors of Korean medicine (KMDs). An online survey was conducted with questions examining the status of ultrasound-guidance usage among KMDs practicing in various KM clinical settings.

Objective: Migraine is a prevalent and disabling neurological disorder affecting a significant proportion of the global population. Although medications are the primary treatment option, their efficacy remains unclear. Thus, alternative therapies such as scalp acupuncture have gained momentum; however, evidence for the effectiveness of scalp acupuncture remains insufficient.

Article Synopsis
  • * The EMS outbreak was linked to impurities in L-tryptophan from certain manufacturing processes, not the substance itself.
  • * A study with broiler chickens found no toxic effects or EMS-related symptoms from L-tryptophan in meat, suggesting that L-tryptophan and its impurities are safe as feed additives.

Article Synopsis
  • * EMS can affect various organ systems, leading to inflammation in muscles, skin, and lungs, and its association with L-tryptophan supplements has become controversial.
  • * Research has explored the connection between impurities in L-tryptophan products and EMS, but studies have yet to produce clear conclusions on the relationship.

  • Lythrum salicaria L., known as purple loosestrife, has a history of medicinal use for internal issues and contains beneficial phytochemicals like orientin, which exhibit various health properties.
  • The study aimed to investigate the anti-obesity effects of Lythri Herba, the plant's aerial part, using both cell cultures and high-fat diet-induced mouse models.
  • Results indicated that Lythri Herba water extracts significantly reduced fat accumulation in cells and prevented weight gain in mice, primarily by inhibiting key enzymes involved in fat production.

Article Synopsis
  • A study assessed the safety of L-tryptophan, produced through fermentation, by giving different doses (0, 500, 1000, 2000 mg/kg/day) to male and female Sprague-Dawley rats for 90 days.
  • No negative health effects were found in any of the rats, even at the highest dose, and this was confirmed during a 4-week recovery period following the treatment.
  • Histological tests also showed no significant changes related to eosinophilia-myalgia syndrome, leading to the conclusion that the dried L-tryptophan product is safe for use as a feed additive.

Background: Scalp acupuncture (SA) is a new acupuncture method that connects head acupoints and aculines, and many systematic reviews (SRs) have been published on its use against neuropsychiatric diseases. However, no overview of SRs on the effectiveness of SA in stroke recovery has been conducted. Therefore, our overview aims to evaluate the methodological bias and reliability of the conclusions of SRs regarding SA for stroke recovery and help clinical decision-makers translate this research into clinical policy and practice.

Mass-correlated rotational alignment spectroscopy resolved the rotational Raman spectra for 5 benzene isotopologues with unprecedented resolution. 13-C isotopologues were characterized at natural abundance. Fitted rotational constants allowed the analysis of effective and equilibrium bond lengths for benzene with sub-mÅ uncertainties.

We present high resolution rotational Raman spectra and derived geometry parameters for benzene. Rotational Raman spectra with sub-5 MHz resolution were obtained high-resolution mass-correlated rotational alignment spectroscopy. Isotopologue spectra for CH, C-CH, CD, and C-CD were distinguished through their correlated mass information.

In South Korea, car insurance that includes medical coverage of traditional Korean medicine (TKM) has increased exponentially. Clinical practice guidelines (CPG) for traffic injuries were established in 2016. We aimed to revise and update de novo CPG and distribute the adapted CPG to TKM practitioners and patients.

Objective: Childhood trauma is the most important environmental factor for several psychiatric disorders. Depressed patients with childhood trauma appear to have severe symptoms that frequently recur. This study investigated whether depressed patients with childhood trauma showed attenuated Nogo event-related potentials (ERPs) and source activity during response-inhibition tasks.

  • The study compared the effectiveness and safety of atomoxetine (ATX) versus OROS methylphenidate (MPH) as additional treatments for adults with ADHD and partially responsive major depressive disorder (MDD).
  • Sixty Korean adults participated in a 12-week trial where both medications showed significant improvements in ADHD and depressive symptoms, with no major differences in effectiveness or side effects between the two.
  • The results indicate that both ATX and MPH are viable adjunctive treatments for this population, but further research is needed to confirm these findings.

Background: Studies in both Eastern & Western countries such as the United States and Europe have evaluated the efficacy of acupuncture for whiplash injury or whiplash-associated disorder (WAD). However, no systematic reviews on the effectiveness of acupuncture on WAD have been conducted since 2014. Therefore, we are planning an updated systematic review of studies published since 2014 to overcome the limitations of existing evidence.

This is the first cost-effectiveness analysis of Chuna manual therapy (CMT) plus usual Korean traditional medicine for traffic accident victims using a randomized controlled trial. A total of 132 participants were equally allocated to the intervention group receiving 6-11 sessions of CMT plus usual Korean traditional medicine care for three weeks or usual care including acupuncture, cupping, herbal medicine, moxibustion, and traditional physiotherapy at three hospitals. At 12 weeks, from a healthcare perspective, the intervention group had significantly higher costs (mean (SD), $778 (435) vs.

Isotope-selective rotational spectroscopy allows to calculate molecular structures independent of assumptions or theoretical predictions. Here, we present the first de novo structure determination based on mass-correlated rotational Raman spectroscopy, analyzing the carbon atom positions of butadiene. Mass correlation allowed us to analyze signals of rare 13C isotopologues at natural abundance, without interference from the main isotopologue signals.

l-threonine, l-tryptophan and l-valine play a fundamental role in animal and human nutrition as essential amino acids required for normal growth. In addition, each amino acid is codified as a generally recognized as safe (GRAS) amino acid for the use in animal feed additives and presents no exposure risk from animal to humans consuming tissues or products from the target animal. Taking into account the important role of mutagenicity and genotoxicity in the risk of the three amino acid additives (l-threonine, l-tryptophan, and l-valine) fermentation products and other unknown impurities and derivatives from (), the safety evaluation of these amino acid additives is not performed.
