CoMn2O4 Catalyst Prepared Using the Sol-Gel Method for the Activation of Peroxymonosulfate and Degradation of UV Filter 2-Phenylbenzimidazole-5-sulfonic Acid (PBSA).

In this study, a bimetallic oxide catalyst of cobalt-manganese (CoMn2O4) was synthesized using the sol-gel method, and it was then characterized using a variety of techniques such as scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) spectroscopy, X-ray photoelectron spectroscopy (XPS), and nitrogen adsorption-desorption isotherms. The obtained novel catalyst, i.e., CoMn2O4, was then used as an activator of peroxymonosulfate (PMS) for the catalytic degradation of a commonly-used UV filter, 2-phenylbenzimidazole-5-sulfonic acid (PBSA) in water. The effects of various factors (e.g., catalyst dosage, PMS concentration, reaction temperature, and pH) in the process were also evaluated. Chemical scavengers and electron paramagnetic resonance (EPR) tests showed that the •OH and SO4•- were the main reactive oxygen species. Furthermore, this study showed that CoMn2O4 is a promising catalyst for activating PMS to degrade the UV filters.

Dejian mind-body intervention improves the cognitive functions of a child with autism.

There has been increasing empirical evidence for the enhancing effects of Dejian Mind-Body Intervention (DMBI), a traditional Chinese Shaolin healing approach, on human frontal brain activity/functions, including patients with autism who are well documented to have frontal lobe problems. This study aims to compare the effects of DMBI with a conventional behavioural/cognitive intervention (CI) on enhancing the executive functions and memory of a nine-year-old boy with low-functioning autism (KY) and to explore possible underlying neural mechanism using EEG theta cordance. At post-one-month DMBI, KY's inhibitory control, cognitive flexibility, and memory functioning have significantly improved from "severely-to-moderately impaired" to "within-normal" range. This improvement was not observed from previous 12-month CI. Furthermore, KY showed increased cordance gradually extending from the anterior to the posterior brain region, suggesting possible neural mechanism underlying his cognitive improvement. These findings have implicated potential applicability of DMBI as a rehabilitation program for patients with severe frontal lobe and/or memory disorders.

Shaolin dan tian breathing fosters relaxed and attentive mind: a randomized controlled neuro-electrophysiological study.

Neuro-electrophysiological studies on meditative breathing revealed its association with either a relaxed or an attentive state. The present study aimed to investigate whether the Shaolin Dan Tian Breathing (DTB) technique, which consists of the Passive and Active subtypes and can be considered as a relaxation exercise and Qigong, would induce both relaxed and attentive states. Twenty-two adults and 22 age-, gender- and education-matched controls received training on the Shaolin DTB (experimental group) and the progressive muscle relaxation respectively for one month. Eyes-closed resting EEG data before and immediately after each type of breathing were obtained individually at baseline and after one-month training. At baseline, the EEG changes after the Shaolin DTB between both groups were comparable. After one-month training, participants in the experimental, but not the control, group showed enhanced temporal alpha asymmetry (an index of relaxation and positive mood) after performing the Passive DTB for five minutes, and enhanced intra- and inter-hemispheric theta coherence (an index of attention and alertness) after performing the Active DTB. The present findings suggested a positive effect of the Shaolin DTB technique on enhancing human neural activity and connectivity, which may possibly enhance mood state and cognitive functions.

Dejian mind-body intervention on depressive mood of community-dwelling adults: a randomized controlled trial.

The present study evaluated the effectiveness of a short-term mind-body intervention program on improving the depressive mood of an adult community sample. Forty adult volunteers with various degrees of depressive mood were randomly assigned to the experimental group (Dejian Mind-Body Intervention, DMBI) and control group (Cognitive-Behavioral Therapy, CBT). For each group, a total of four 90-min weekly sessions were conducted. Treatment-related changes were measured using the Beck Depression Inventory (BDI-II), an electroencephalographic indicator of positive affect (i.e., prefrontal activation asymmetry), and self-report ratings on physical health. Results indicated that both the DMBI and the CBT group demonstrated significant reduction in depressive mood. However, among individuals with moderate to severe depressive mood at baseline, only those in the DMBI but not the CBT group showed significant reduction in depressive mood. Besides, only the DMBI group demonstrated a significant increase in prefrontal activation asymmetry, suggesting increase in positive affect. While most psychological therapies for depressive mood normally take several months to show treatment effect, the present findings provided initial data suggesting that the DMBI was effective in improving depressive mood of community adults after 1 month of training.

An herbal nasal drop enhanced frontal and anterior cingulate cortex activity.

The present study examined the neuro-electrophysiological activity of the brain associated with the application of a herbal remedy developed by a Shaolin monk based upon the Chan healing principle of clearing the orifices (i.e., the nasal cavities). A repeated-measures design was used. Fourteen normal adults were administered herbal remedy and saline solution intranasally on separate sessions. Two intervals of eyes-closed resting EEG data were obtained individually before and after each administration. Results showed that only the herbal remedy but not the saline solution induced elevation in cordance, an index correlated with cerebral perfusion, in the anterior brain region. In addition, the activity of the anterior cingulate cortex (ACC), as examined by the LORETA analysis, was also increased after the application of the herbal remedy but not saline solution. The present study provided some preliminary evidence suggesting that the herbal nasal drop enhanced the activity of the frontal lobe and ACC. Implications for the potential clinical application of the herbal remedy to treat patients with frontal lobe disorders were discussed.

Dejian mind-body intervention improves the functioning of a patient with chronic epilepsy: a case report.

BACKGROUND: This is a case report that illustrates the effect of the Dejian Mind-Body Intervention (DMBI) on a 22-year-old chronic epileptic male (onset at age two) suffering from severe cognitive impairments as a result of a serious seizure two years ago. The DMBI is a healing program developed for modern lifestyle based on the traditional Chinese Shaolin Chanwuyi healing approach. CASE PRESENTATION: Through a four-month treatment in which he adopted the DMBI specified vegetarian diet, applied an herbal remedy, and practiced Natural Dan Tian Breathing (a type of mind-body exercise), the patient showed significant improvements in language, memory, attention, behavioral initiation, emotional control, social functioning, and overall quality of life. In addition, the DMBI has a positive effect on his brain electrophysiological activities, as indicated by his suppressed delta power (slow wave) and enhanced alpha power (fast wave), and his elevated cordance value (an index associated with cerebral perfusion) in the left frontal and temporal regions. Such neural activity alteration was in line with his observed cognitive improvements. CONCLUSION: These results provide evidence to support the therapeutic effect of the DMBI and its potential clinical application on treating chronic neurological patients.
