Amyotrophic lateral sclerosis (ALS) is a progressively paralytic neurodegenerative disease that can be caused by mutations in Cu/Zn-superoxide dismutase 1 (SOD1). Transgenic mice that overexpress mutant SOD1 develop paralysis and accumulate aggregates of mutant protein in the brainstem and spinal cord. Bee venom (BV), which is also known as apitoxin, is extracted from honeybees and is commonly used in oriental medicine for the treatment of chronic rheumatoid arthritis and osteoarthritis. The purpose of the present study was to determine whether BV affects misfolded protein aggregates such as alpha-synuclein, which is a known pathological marker in Parkinson disease, and ubiquitin-proteasomal activity in hSOD1G93A mutant mice. BV was bilaterally administered into a 98-day-old hSOD1G93A animal model. We found that BV-treated hSOD1G93A transgenic mice showed reduced detergent-insoluble polymerization and phosphorylation of α-synuclein. Furthermore, phosphorylated or nitrated α-synuclein was significantly reduced in the spinal cords and brainstems of BV-treated hSOD1G93A mice and reduced proteasomal activity was revealed in the brainstems of BV-treated symptomatic hSOD1G93A. From these findings, we suggest that BV treatment attenuates the dysfunction of the ubiquitin-proteasomal system in a symptomatic hSOD1G93A ALS model and may help to slow motor neuron loss caused by misfolded protein aggregates in ALS models

An Analysis on Size Suitability of Protective Masks

Since a mask which is not suitable for a human face type has a low protection effect, it is necessary to design the shape of the mask reflecting the face shape of the human body in consideration of the size and shape of each part of the face. The masks analyzed in this study are classified into a yellow dust mask(sanitation mask) and a Fine dust protective mask sold in four countries of Korea, China, the US and England. The standard of Korea is KF(Korea Filter, particle blocking function), which is divided into KF80, KF94 and KF99, which are certified by Ministry of Food and Drug Safety. The standard of the US is N95 that is certified by the National Institute for Occupational Safety and Health (NIOSH). The result ofanalyzing the sizes of products is as follows. First, there was a significant difference among the products in the 3 horizontal length items of Nose-Tragion A, Lip-Tragion A, Menton-Tragion B and the 1 vertical length item of chin-menton length. The Nose-Tragion A was the U.S. 12.2cm \u3e England 10.8cm \u3e China 10.7cm \u3e Korea 9.6cm. The result of analyzing fine dust masks in the market showed that they mark the structures, forms and penetration ratio of fine dust, but there is no size standard for each size. Therefore, it is necessary to establish standards of each size for suitable pattern designs for face shapes in each country

Validation Study of Kim's Sham Needle by Measuring Facial Temperature: An N-of-1 Randomized Double-Blind Placebo-Controlled Clinical Trial

Introduction. In 2008, Kim's sham needle was developed to improve the quality of double-blinded studies. The aim of this study is to validate Kim's sham needle by measuring facial temperature. Methods. We designed “N-of-1” trials involving 7 smokers. One session was composed of 2 stimulations separated by a 2 h washout period. Six sessions were applied daily for all subjects. Infrared thermal imaging was used to examine the effects of acupuncture (HT8, KI2) on facial temperature following smoking-induced decrease. Results. All subjects demonstrated decreased temperatures after sham needle treatment, but 5 of the 7 subjects showed increased temperatures after real needle treatment. 6 of the 7 subjects showed a significant difference (P < 0.05) between treatments with real and sham needles. Thus, the physiological stimulation of Kim's sham needle is different from that of a real needle, suggesting that Kim's sham needle is a potential inactive control intervention

Utilization of Laboratory Tests for Tuberculosis and Mycobacterial Disease in Korea

AbstractObjectivesIn Korea, a large portion of tuberculosis (TB) patients are diagnosed and treated in private institutes. Laboratory tests are crucial for TB control. There are many possible problems using laboratory tests in the private sector. In this study, we aimed to investigate the characteristics and trends of utilizing laboratory tests for TB and mycobacterial diseases in the private sector by analyzing the National Health Insurance (NHI) database.MethodsAfter selecting TB or other mycobacteria-related test items, we searched the number and cost of each item on the website of the Health Insurance Review and Assessment Service using the code of each test from 2007 to 2012.ResultsOur data revealed that the number and cost of tests drastically increased between 2007 and 2012. Culture and molecular tests primarily contributed to the tremendous increases. For each year, concentrated smearing and fluorochrome staining were more commonly used. The number of serologic tests for latent TB infection stagnated, despite the expansion of contact investigation.ConclusionThe NHI data could be considerably useful for understanding the utilization trends of laboratory tests for TB and mycobacterial diseases in Korea. Our data showed that TB laboratory systems have recently improved. In this study, many issues were noticed. Therefore, solutions to these issues are required and the continued monitoring of NHI data regarding laboratory diagnosis

Δπ=0 reverse osmosis enriches a high osmotic pressure solution from a low-titre fermentation broth to a saturated solution or salt form using RO and NF membranes

Diverse biotechnology products are produced by microbial or eukaryotic cell fermentations in aqueous solutions. Removal of water is inevitable to enrich the product into a concentrated solution or into solid forms (such as crystals). The theoretical minimum energy required to remove 1 m3 of water is 716 kWh for thermal methods and 1 kWh for reverse osmosis (RO). In practice, the thermal methods equipped with heat energy recycling needs about 25 kWh to remove 1 m3 of water, and the RO methods needs about 4 kWh since extra energy (3 kWh) is required to operate pumps and other facilities in a plant. In general, membrane processes need less energy than thermal processes since there is no phase change in the separation processes and do not damage heat-sensitive biotechnology products. While both RO and NF membranes are permeable to water, RO membrane retains NaCl molecules and NF membrane is permeable to NaCl molecules, which is useful to remove inorganic salts from the products. Unlike thermal processes, the application of the membrane processes is limited by high osmotic pressure as the product solution is enriched by removing water. Chang et al. (2013) proposed a concept of osmotic pressure-free reverse osmosis (Δπ=0 RO) that overcomes this limitation and allows concentration of any solution with high osmotic pressure to its saturation point and further to crystal form. Δπ=0 RO, a two-component system, is distinct from 3-component forward osmosis and does not require the third component (draw component or extraction solvent) that must be separated from the aqueous solution at the end. This presentation will compare (1) ways of Δπ=0 RO technologies in desalination, and, furthermore (2) dewatering and desalination of high osmotic solutions of NaCl (343 bar), volatile fatty acids (400 – 600 bar), and fuel ethanol (6000 bar) with thermal separation methods in terms of energy consumption and potential of Δπ=0 RO technology.

Melittin restores proteasome function in an animal model of ALS

Amyotrophic lateral sclerosis (ALS) is a paralyzing disorder characterized by the progressive degeneration and death of motor neurons and occurs both as a sporadic and familial disease. Mutant SOD1 (mtSOD1) in motor neurons induces vulnerability to the disease through protein misfolding, mitochondrial dysfunction, oxidative damage, cytoskeletal abnormalities, defective axonal transport- and growth factor signaling, excitotoxicity, and neuro-inflammation

The Characteristics of Action Potentials in Primo Vessels and the Effects of Acetylcholine Injection to the Action Potentials

In a previous study, we found that Primo vessels generate different action potentials in smooth muscles, but this study compared the pulse shape to distinguish the two tissues. Thus, a more sophisticated extracellular experiment was performed in this study using an acetylcholine injection; we then observed changes in the amplitude, FWHM (full width at half maximum), and period to explore Primo vessel function. A third type of pulse was recorded for Primo vessels. We observed fast depolarizing and repolarizing phases for this pulse. Further, its FWHM was 30 ms between smooth muscles and neurons. Acetylcholine affected only the period. The amplitude and FWHM were consistent after injection. Primo-vessels generated action potentials at twice the frequency after injection. From the results, we speculate that Primo-vessels perform a role in transferring signals in a different manner, which may be relevant for acupuncture treatment

Broussonetia papyrifera Root Bark Extract Exhibits Anti-inflammatory Effects on Adipose Tissue and Improves Insulin Sensitivity Potentially Via AMPK Activation

The chronic low-grade inflammation in adipose tissue plays a causal role in obesity-induced insulin resistance and its associated pathophysiological consequences. In this study, we investigated the effects of extracts of Broussonetia papyrifera root bark (PRE) and its bioactive components on inflammation and insulin sensitivity. PRE inhibited TNF-alpha-induced NF-kappa B transcriptional activity in the NF-kappa B luciferase assay and pro-inflammatory genes&apos; expression by blocking phosphorylation of I kappa B and NF-kappa B in 3T3-L1 adipocytes, which were mediated by activating AMPK. Ten-week-high fat diet (HFD)-fed C57BL6 male mice treated with PRE had improved glucose intolerance and decreased inflammation in adipose tissue, as indicated by reductions in NF-kappa B phosphorylation and pro-inflammatory genes&apos; expression. Furthermore, PRE activated AMP-activated protein kinase (AMPK) and reduced lipogenic genes&apos; expression in both adipose tissue and liver. Finally, we identified broussoflavonol B (BF) and kazinol J (KJ) as bioactive constituents to suppress pro-inflammatory responses via activating AMPK in 3T3-L1 adipocytes. Taken together, these results indicate the therapeutic potential of PRE, especially BF or KJ, in metabolic diseases such as obesity and type 2 diabetes

Effects of Qigong on Depression: A Systemic Review

Physical exercises and relaxation have been found to be beneficial for depression. However, there is little evidence on the use of Qigong, a mind-body practice integrating gentle exercise and relaxation, in the management of depression. The aim of this paper is to evaluate the effects of Qigong on depression. The paper examined clinical trials measuring the effect of Qigong on depression within six large-scale medical research databases (PubMed, Medline, ProQuest, Science Direct, EMBASE, and PsycInfo) till October 2011. Key words “Qigong,” “depression,” and “mood” were used. Ten studies were identified as original randomized controlled trial (RCT) studies investigating the effect of Qigong on depression as primary (n = 2) or secondary outcome (n = 8). Four studies reported positive results of the Qigong treatment on depression; two reported that Qigong effect on depression was as effective as physical exercise. One study reported that Qigong was comparable to a conventional rehabilitation program, but the remaining three studies found no benefits of Qigong on depression. While the evidence suggests the potential effects of Qigong in the treatment of depression, the review of the literature shows inconclusive results. Further research using rigorous study designs is necessary to investigate the effectiveness of Qigong in depression

Myoepitheliomas of the Soft Palate: Helical CT Findings in Two Patients

We describe the enhancement patterns of myoepithelioma in two patients with a soft palate mass. In the first case, helical CT revealed a faintly enhancing mass. Histologically, the tumor was composed of plasmacytoid cells in a background of rich myxoid stroma. Immunostaining for CD34 showed scanty blood vessels. In the second case, helical CT revealed an intensely enhancing mass. Histologically, the mass was a cellular tumor with fibrous stroma. Immunostaining for CD34 also showed frequent blood vessels
