This study was performed to examine the effects of various macromolecules in in vitro growth (IVG) media on the growth, maturation, and parthenogenesis (PA) of pig oocytes derived from small antral follicles (SAF). Immature oocytes were cultured for two days in IVG medium supplemented with 10% (v/v) fetal bovine serum (FBS), 10% (v/v) pig follicular fluid (PFF), 0.4% (w/v) bovine serum albumin (BSA), or 0.1% (w/v) polyvinyl alcohol (PVA) and then maintained for 44 h for maturation. After IVG, the mean diameters of the SAF treated with FBS, PVA, and no IVG-MAF (113.0–114.8 µm) were significantly larger than that of no IVG-SAF (111.8 µm). The proportion of metaphase II oocytes was higher in PFF (73.6%) than in BSA (43.5%) and PVA (53.7%) but similar to that in the FBS treatment (61.5%). FBS and PFF increased cumulus expansion significantly compared to PVA and BSA while the intraoocyte glutathione content was not influenced by the macromolecules. Blastocyst formation of PA oocytes treated with FBS (51.8%), PFF (50.4%), and PVA (45.2%) was significantly higher than that of the BSA-treated oocytes (20.6%). These results show that the PFF and FBS treatments during IVG improved the growth, maturation, and embryonic development of SAF.

Journal of Veterinary Science 2022;23(2):e31-
Background:
Compared to medium containing 108 mM sodium chloride (NaCl), in vitromaturation (IVM) using a simple medium with reduced (61.6 mM) NaCl increases the cytoplasmic maturation and embryonic development of pig oocytes.
Objectives:
This study determines the effect of a complex medium containing reduced NaCl on the IVM and embryonic development of pig oocytes.
Methods:
Pig oocytes were matured in Minimum Essential Medium Eagle-alpha modification (αMEM) supplemented with 61.6 (61αMEM) or 108 (108αMEM) mM NaCl, and containing polyvinyl alcohol (PVA) (αMEMP) or pig follicular fluid (PFF) (αMEMF). Medium-199 (M199) served as the control for conventional IVM. Cumulus cell expansion, nuclear maturation, intra-oocyte glutathione (GSH) contents, size of perivitelline space (PVS), and embryonic development after parthenogenesis (PA) and somatic cell nuclear transfer (SCNT) were evaluated after IVM.
Results:
Regardless of PVA or PFF supplementation, oocytes matured in 61αMEM showed increased intra-oocyte GSH contents and width of PVS (p < 0.05), as well as increased blastocyst formation (p < 0.05) after PA and SCNT, as compared to oocytes matured in 108αMEMP and M199. Under conditions of PFF-enriched αMEM, SCNT oocytes matured in 61αMEMF showed higher blastocyst formation (p < 0.05), compared to maturation in 108αMEMF and M199, whereas PA cultured oocytes showed no significant difference.
Conclusions
IVM in αMEM supplemented with reduced NaCl (61.6 mM) enhances the embryonic developmental competence subsequent to PA and SCNT, which attributes toward improved oocyte maturation.

OBJECTIVE: The purpose of this study was to compare clinical and radiological outcomes of percutaneous endoscopic lumbar discectomy (PELD) and open lumbar microdiscectomy (OLM) for recurrent disc herniation. METHODS: Fifty-four patients, who underwent surgery, either PELD (25 patients) or repeated OLM (29 patients), due to recurrent disc herniation at L4-5 level, were divided into two groups according to the surgical methods. Excluded were patients with sequestrated disc, calcified disc, severe neurological deficit, or instability. Clinical outcomes were assessed using Visual Analogue Scale (VAS) score and Oswestry Disability Index (ODI). Radiological variables were assessed using plain radiography and/or magnetic resonance imaging. RESULTS: Mean operating time and hospital stay were significantly shorter in PELD group (45.8 minutes and 0.9 day, respectively) than OLM group (73.8 minutes and 3.8 days, respectively) (p < 0.001). Complications occurred in 4% in PELD group and 10.3% in OLM group in the perioperative period. At a mean follow-up duration of 34.2 months, the mean improvements of back pain, leg pain, and functional improvement were 4.0, 5.5, and 40.9% for PELD group and 2.3, 5.1, and 45.0% for OLM group, respectively. Second recurrence occurred in 4% after PELD and 10.3% after OLM. Disc height did not change after PELD, but significantly decreased after OLM (p = 0.0001). Neither sagittal rotation angle nor volume of multifidus muscle changed significantly in both groups. CONCLUSION: Both PELD and repeated OLM showed favorable outcomes for recurrent disc herniation, but PELD had advantages in terms of shorter operating time, hospital stay, and disc height preservation.

8.Inflammasomes, multi-cellular protein complex in myeloid cells, induce several metabolic diseases via interleukin-1beta maturation.
Journal of Biomedical Research 2013;14(4):195-200
Inflammation mainly mediated by innate immune cells as the first line of host defense against pathogens is an acute response that limits tissue damage and eliminates pathogens in the body. In triggering inflammation, several pattern recognition receptors work together; membrane-associated Toll-like receptors, c-type lectin receptors, retinoic acid-inducible gene-like helicase receptors, absent in melanoma-like receptors, and cytosolic nucleotide-binding domain and leucine-rich repeat receptors. Among them, inflammasome is a newly trigger of inflammation in response to exogenous and endogenous stimuli and its activation leads to the assembly of multiprotein platforms composed of NLRP3 (NOD-like receptor family, pyrin domain containing 3), ASC (apoptosis associated speck-like protein containing a CARD), and procaspase 1. Thus, the activated inflammasome activates caspase 1, resulting in processing and secretion of interleukin (IL)-1beta. Recent emerging data suggest that dysregulated metabolites, i.e., amyloids, ceramides, and cholesterol crystals, have been classified as inflammasome activators. In addition, IL-1beta may play a critical role in the pathogenesis of chronic inflammation-induced disorders such as Alzheimer's diseases, type 2 diabetes, and atheriosclerosis. This review introduces the basic concept of inflammasome activation and auto-inflammatory diseases. In addition, it discusses the updated signaling models of inflammasome activation that link metabolic dysfunction in order to outline future therapeutic approaches to inflammasome-mediating diseases.

OBJECTIVES: The health examination survey was conducted in order to estimate the prevalence of major chronic diseases in a community. METHODS: A multi-stage stratified probability sample of 1,656 persons, aged from 20 to 69 years, was drawn out from Kuri City. All sampled persons were personally informed of the purpose, content and procedures of the survey and mobile examination center was run between 6 AM and 9 PM for the convenience of the participants. RESULTS: 854 persons (339 males and 515 females) completed this survey with a response rate of 53.4%. Prevalent diseases in male were hypertension(19.0%), HBs Ag carrier(9.8%), impaired glucose tolerance(8.7%), diabetes mellitus(6.3%), hypercholesterolemia(3.4%), anemia(2.7%) and degenerative arthritis(2.6%) in order of prevalence rate. Prevalent diseases in female were osteoporosis(22.5%), impaired glucose tolerance(17.3%), anemia(12.8%), hypertension(12.4%), degenerative arthritis (6.6%), HBs Ag carrier(5.8%), diabetes mellitus(5.4%) and hypercholesterolemia(3.5%) in order of prevalence rate. CONCLUSIONS: This results suggest that hypertension was most prevalent in adult male whereas diabetes mellitus including IGT, osteoporosis were most prevalent in adult female, in Kuri City.

This study was conducted to determine the effects of biophoton treatment during in vitro maturation (IVM) and/or in vitro culture (IVC) on oocyte maturation and embryonic development in pigs. An apparatus capable of generating homogeneous biophoton energy emissions was placed in an incubator. Initially, immature pig oocytes were matured in the biophoton-equipped incubator in medium 199 supplemented with cysteine, epidermal growth factor, insulin, and gonadotrophic hormones for 22 h, after which they were matured in hormone-free medium for an additional 22 hr. Next, IVM oocytes were induced for parthenogenesis (PA) or provided as cytoplasts for somatic cell nuclear transfer (SCNT). Treatment of oocytes with biophoton energy during IVM did not improve cumulus cell expansion, nuclear maturation, intraoocyte glutathione content, or mitochondrial distribution of oocytes. However, biophoton-treated oocytes showed higher (p < 0.05) blastocyst formation after PA than that in untreated oocytes (50.7% vs. 42.7%). In an additional experiment, SCNT embryos produced from biophoton-treated oocytes showed a greater (p < 0.05) number of cells in blastocysts (52.6 vs. 43.9) than that in untreated oocytes. Taken together, our results demonstrate that biophoton treatment during IVM improves developmental competence of PA- and SCNT-derived embryos.
