Objective : As the average lifespan of human increases, osteoporosis and osteoporosis-related fractures have become major health care problems. Despite recent advances in medical treatment, few studies have assessed the recognition of osteoporosis in general adults. This study examined the recognition of osteoporosis and analyzed the relating factors. Method : A population-based sample of 1086 adults in Asan-city, Korea was investigated with questionnaires and height, weight, Information regarding the general characteristics(gender, age, economic state), lifestylef exercise, smoking, alcohol),medical history(progestin, GH, steroid, calcitonin, PTH), demographic parameter, obesity, stress, and family history was collected through an interview using a structural questionnaire. The level of obesity was measured by the body mass index(BMI). BMD(Bone mineral density) at the lumbar spine and femoral neck was measured by dual energy X-ray absorptiometry. Osteoporosis was considered to be T-score below -2.5. Results : The prevalence of osteoporosis increased progressively with age, decreased with BMI and predominant in women by the result of x^(2) -test, T-test. Age, weight, BMI were significantly correlated with osteoporosis by the result of Pearson correlation ana1ysis(P<0.05). And age, gender, BMI, family history of osteoporosis were proved to be significant risk factors of osteoporosis by the result of multiple logistic regression(P<0.05). Conclusion : These results suggest that age, gender, BMI might be the most important risk factors of osteoporosis. And the history taking about family history of osteoporosis is helpful for diagnosing osteoporosis.
Bacillus species related to food poisoning
Oh, Mi-Hwa,Kim, Gun-Hee 식물자원연구소 덕성여자대학교 2006 植物資源硏究誌 Vol.5 No.-
The major concern in the food industry is the outgrowth of pathogenic Bacillus species which have the potential to cause a food poisoning incident. Bacillus cereus is the most prevalent pathogenic Bacillus species found in food and other industrial processes. However, other species in the genus Bacillus, including B. subtilis, B. licheniformis, B. brevis, B. pumilus and B. thuringiensis have been implicated as potential agents of food poisoning.

Chronic spontaneous urticaria (CSU) is defined as the occurrence of spontaneous wheals, angioedema, or both for >6 weeks in the absence of specific causes. It is a common condition associated with substantial disease burden both for affected individuals and societies in many countries, including Korea. CSU frequently persists for several years and requires high-intensity treatment; therefore, patients experience deteriorations in quality of life and medication-associated complications. During the last decade, there have been major advances in the pharmacological treatment of CSU and there is an outstanding need for evidence-based guidelines that reflect clinical practice in Korea. The guidelines reported here represent a joint initiative of the Korean Academy of Asthma, Allergy and Clinical Immunology and the Korean Dermatological Association, and aim to provide evidence-based guidance for the management of CSU in Korean adults and children. In Part 1, disease definition, guideline scope and development methodology as well as evidence-based recommendations on the use of antihistamines and corticosteroids are summarized.

Endometrial stromal tumors are the second most common uterine sarcomas. They are divided into three types; endometrial stromal nodule, endometrial stromal sarcoma (ESS), and undifferentiated endometrial sarcoma (UES). UES is much less common than ESS. And it has a much more aggressive clinical course and poorer prognosis than ESS. Case: A 47-year-old woman presented to our hospital with a 4-month history of irregular vaginal bleeding. TVUS revealed a vascularized mass mimicking submucosal myoma in the uterine endometrial cavity. MRI was performed. A 5.9 × 5.1 × 4.8 cm submucosal mass filled up the endometrial cavity. Hysterocopy examination confirmed the protruding mass at the lower portion of the endometrial cavity. The frozen section of the hysteroscopy was reported as malignancy. Subsequently, the patient underwent laparoscopic hysterectomy with bilateral salpingo-oophorectomy and bilateral pelvic lymph node dissection. There was no cancerous involvement in 19 dissected lymph nodes. The results of immunohistochemical stainings were positive for vimentin and CD56, a few positive for CD68, and negative for smooth muscle actin, desmin, CD10, CD34, pan-cytokeratin, HMB-45, S-100 protein, chromogranins and synaptophysin. Based on these histomorphologic findings, the diagnosis of UES was made. The patient was referred to an oncological center for chemotherapy and radiation therapy. Conclusion: It is important to establish a proper classification of endometrial stromal tumors by cytologic and immunohistochemical findings becase of different clinical course and prognosis.

<P>An artificial three-dimensional (3D) culture system that mimics the tumor microenvironment in vitro is an essential tool for investigating the cross-talk between immune and cancer cells in tumors. In this study, we developed a 3D culture system using an electrospun poly(ε-caprolactone) (PCL) nanofibrous scaffold (NFS). A hybrid NFS containing an uninterrupted network of nano- and submicron-scale fibers (400 nm to 2 µm) was generated by deposition onto a stainless steel mesh instead of an aluminum plate. The hybrid NFS contained multiplanar pores in a 3D structure. Surface-seeded mouse CT26 colon cancer cells and bone marrow-derived dendritic cells (BM-DCs) were able to infiltrate the hybrid NFS within several hours. BM-DCs cultured on PCL nanofibers showed a baseline inactive form, and lipopolysaccharide (LPS)-activated BM-DCs showed increased expression of CD86 and major histocompatibility complex Class II. Actin and phosphorylated FAK were enriched where unstimulated and LPS-stimulated BM-DCs contacted the fibers in the 3D hybrid NFS. When BM-DCs were cocultured with mitoxantrone-treated CT26 cells in a 3D hybrid NFS, BM-DCs sprouted cytoplasm to, migrated to, synapsed with, and engulfed mitoxantrone-treated CT26 cancer cells, which were similar to the naturally occurring cross-talk between these two types of cells. The 3D hybrid NFS developed here provides a 3D structure for coculture of cancer and immune cells.</P>

Kim, Gun-Hwa,Choi, Chi W,Park, Edmond C,Lee, Sang-Yeop,Kim, Seung Ii BENTHAM SCIENCE PUBLISHERS 2014 CURRENT PROTEIN AND PEPTIDE SCIENCE Vol.15 No.7
<P>The secretion of extracellular membrane vesicles (EMVs) is a common phenomenon that occurs in archaea, bacteria, and mammalian cells. EMVs contain biologically active proteins, which have diverse roles in biological processes. The outer membrane vesicles (OMVs) of Gram-negative bacteria and membrane vesicles (MVs) of Gram-positive bacteria have been discovered in various species. The main issues related to bacterial EMVs are their virulence, biogenesis mechanisms, host cell interaction mechanisms, and their potential use as new vaccine candidates. Recently, proteomics has become an essential tool for the characterization of EMVs. Proteomics is useful for the identification, quantification, and protein-protein interaction analysis of EMV protein components. This review describes the current understanding of secretory EMVs based on proteomic methods and the characteristics of various bacterial secretory EMVs. Finally, evidence for their potential roles and future applications are discussed.</P>
