Although modern medicine hasmade great strides in the management of burn injuries, associated complications such as pain, infection, dyspigmentation, and scarring have yet to be fully dealt with. Although skin grafting and meshing are routinely performed on burn patients, this method poses a risk for adverse effects. Activated autologous platelet-rich plasma (aaPRP), which is increasingly used in the field of plastic surgery, contains growth factors beneficial for wound regeneration. Seven cases of burns with varying severity and conditions that were treated with intralesional subcutaneous injection and intravenous aaPRP are presented and discussed herein. This case series indicates that subcutaneous and intravenous aaPRP is a safe procedure with the potential to be an alternative when skin grafting cannot be done or as an adjunct treatment to skin grafting.
Synthesis and characterization of sol-gel derived ZrB2-ZrC compounds
Karina S. Campos 한양대학교 세라믹연구소 2014 Journal of Ceramic Processing Research Vol.15 No.6
In this work ZrB2-ZrC compounds were prepared by sol-gel process. These materials were examined by X-ray diffraction (XRD), thermogravimetric (TG) analysis, laser granulometry, scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), and nitrogen adsorption tests. Thermodynamic calculations were carried out using the FactSage® thermochemical software and databases. XRD revealed that ZrB2 and ZrC are the major phases present in the materials obtained in this study. It was observed that the relative amount of ZrB2 and ZrC in these samples can be tailored by controlling the concentration of H3BO3 in the starting solution. On one hand, laser granulometry and SEM tests revealed that the ZrB2- ZrC compounds prepared in this work show a coarse particle size distribution. On the other hand, they exhibited remarkable specific surface areas (about 150 m2 /g).

The probiotic market is constantly continuing to grow, concomitantly with a widening in the range and diversity of probiotic products. Probiotics are defined as live microorganisms that provide a benefit to the host when consumed at a proper dose; the viability of a probiotic is therefore of crucial importance for its efficacy. Many products undergo lyophilization for maintaining their shelf-life. Unfortunately, this procedure may damage the integrity of the cells due to stress conditions during both the freezing and (vacuum-) drying process, thereby impacting their functionality. We propose a lysine-based mixture for rehydration of freeze-dried probiotics for improving their viability during in vitro simulated gastric and duodenum stress conditions. Measurement of the zeta potential served as an indicator of cell integrity and efficacy of this mixture, while functionality was estimated by adhesion to a human enterocyte-like Caco-2 cell-line. The freeze-dried bacteria exhibited a significantly different zeta potential compared to fresh cultures; however, this condition could be restored by rehydration with the lysine mixture. Recovery of the surface charge was found to influence adhesion ability to the Caco-2 cell-line. The optimum lysine concentration of the formulation, designated “Zeta-bio”, was found to be 0.03 M for improving the viability of Lactiplantibacillus plantarum Lp-115 by up to 13.86% and a 7-strain mixture (400B) to 41.99% compared to the control rehydrated with distilled water. In addition, the lysine Zeta-bio formulation notably increased the adherence ability of lyophilized Lp-115 to the Caco-2 cell-line after subjected to the in vitro stress conditions of the simulated gastrointestinal tract passage.

Karina G. Perez-Rubio,Miriam Mendez-del Villar,Marisol Cortez-Navarrete 한국식품영양과학회 2022 Journal of medicinal food Vol.25 No.7
Garlic (Allium sativum L.) is a popular spice that has been widely used for thousands of years in traditional medicine. Several organosulfur compounds in garlic have been linked to its beneficial effects on health. Evidence from preclinical studies and clinical trials supports garlic's antihypertensive, antidiabetic, antiobesity, and hypolipidemic effects. This study aims to summarize clinical trial evidence regarding the effects of garlic on metabolic diseases and its mechanisms of action.
Livelihoods for women in Mindanao : A post-conflict reconstruction approach
Karina R. SANTILLAN 이화여자대학교 아시아여성학센터 2015 Asian Journal of Women's Studies(AJWS) Vol.21 No.1
Mahigit dalawang milyong tao ang nawalan ng tahanan at lumikas dahil sa kaguluhan sa Mindanao noong 2000 hanggang 2009. Sa panandaliang paghupa ng kaguluhan, sila ay bumalik sa kanilang komunidad upang simulan ang proseso ng muling pagtatag ng kanilang buhay. Ihinahayag ng artikulong ito kung ano ang naiambag ng mga babae sa proseso ng pagtatag matapos ang kaguluhan. Ito ay isang pag-aaral kung paano nakatulong ang mga babae sa pamamagitan ng paglahok sa mga gawaing pangkabuhayan. Tinitignan nito ang kinahinatnan ng limang proyektong pangkabuhayan na naisakatuparan sa indanao sa mga taong 2000 hanggang 2010. Sinukat ang saklaw ng ambag ng mga kababaihan sa proseso ng pagtatag sa pamamagitan ng pagtukoy ng mga benepisyong naibigay nila sa kanilang pamilya at komunidad, na siyang naging bunga ng kanilang paglahok sa mga gawaing pangkabuhayan. Pinatotohanan ng artikulong ito na ang paglahok ng mga babae sa iba’t ibang gawaing pangkabuhayan ay nakatulong sa proseso ng pagtatag sa aspetong ekonomiko, sosyal at politikal ng mga komunidad na apektado ng kaguluhan. Ikinikumpara din ng artikulong ito ang paglahok ng mga babae sa mga gawaing pangkabuhayan sa ibang mga paraan ng pagtatag na naisakatuparan ng mga gobiyerno at mga ahensya. Isinusulong nito ang paglaan ng mga gawaing pangkabuhayan na hinihimok ang paglahok ng mga babae bilang isang mahusay ng paraan para maisakatuparan ang proseso ng pagtatag matapos ang kaguluhan. The conflict inMindanao has displaced over two million people in the period 2000 to 2009. As it subsides, the displaced return to their communities and begin the process of reconstruction. This paper studies how women contributed to the post-conflict reconstruction of Mindanao by engaging in livelihood activities. It explores five different livelihood intervention projects implemented in Mindanao between 2000 and 2010. The extent of women’s contribution to post-conflict reconstruction is measured by identifying the benefits gained at household and community levels, generated by women’s livelihood work. I argue that women’s participation in such activities have led to economic, social and political reconstruction of the communities affected by in Mindanao. This paper also compares the women’s livelihoods approach with other reconstruction strategies. It also illustrates that interventions for reconstruction therefore must include livelihood programs that encourage women’s participation, as exemplified by the experience of Mindanao.

The paper explores how experts in Japan assess and understand the process and consequences of the unification of the Republic of Korea (South Korea) and the Democratic People’s Republic of Korea (North Korea). Based on the theoretical framework of interrelations between social identity and power, this paper asks how Japanese experts frame the process of Korean unification and evaluate its impact on Japan. The data was collected in Tokyo, Japan, through 37 semi-structured and focus group interviews, then examining these interviews using phenomenological and critical discourse analysis. Analysis of data reveals the existence of four competing narratives rooted in the complex relations between meaning of identity, concepts of power, and Japanese policies toward the unification process. The paper expands the description of two narratives currently present in the existing literature, (1) threat and (2) peace, and introduces two new narratives, (3) democratic processes and (4) restorative justice. The final discussion explores how three groups of factors, (1) regional dynamics, (2) domestic policy, and (3) possible models of unification, influence the prevalence of a particular narrative as well as resulting policies of Japan toward Korean unification.

Background: Transcutaneous electrical nerve stimulation (TENS), manual acupuncture (MA), and spinal cord stimulation (SCS) are used to treat a variety of pain conditions. These non-pharmacological treatments are often thought to work through similar mechanisms, and thus should have similar effects for different types of pain. However, it is unclear if each of these treatments work equally well on each type of pain condition. The purpose of this study was to compared the effects of TENS, MA, and SCS on neuropathic, inflammatory, and non-inflammatory pain models. Methods: TENS 60 Hz, 200 μs, 90% motor threshold (MT), SCS was applied at 60 Hz, an intensity of 90% MT, and a 0.25 ms pulse width. MA was performed by inserting a stainless-steel needle to a depth of about 4-5 mm at the Sanyinjiao (SP6) and Zusanli (ST36) acupoints on a spared nerve injury (SNI), knee joint inflammation (3% carrageenan), and non-inflammatory muscle pain (intramuscular pH 4.0 injections) in rats. Mechanical withdrawal thresholds of the paw, muscle, and/or joint were assessed before and after induction of the pain model, and daily before and after treatment. Results: The reduced withdrawal thresholds were significantly reversed by application of either TENS or SCS (P < 0.05). MA, on the other hand, increased the withdrawal threshold in animals with SNI and joint inflammation, but not chronic muscle pain. Conclusions: TENS and SCS produce similar effects in neuropathic, inflammatory and non-inflammatory muscle pain models while MA is only effective in inflammatory and neuropathic pain models.
