Byungjin Kang, Jeong-Rok Kim, Jae-Min Shin, Il-Ho Park, Heung-Man Lee
Objectives: Nasal packing after endoscopic sinus surgery is frequently used to control postoperative bleeding, enhance the wound healing process, and prevent lateralization of the middle turbinate, which causes insufficient ventilation. Many biodegradable materials have been developed to reduce pain and mucosal damage during packing removal. The purpose of this study was to compare the efficacy of Guardcel (Genewel Co.) middle meatal packing with a traditional nonabsorbable middle meatal packing, Merocel (Medtronic Xomed), on wound healing and patient satisfaction...

Ginsenosides, which are the active materials of ginseng, have biological functions that include anti-osteoporotic effects. Aqueous ginseng extract inhibits osteoclast differentiation induced by receptor activator of NF-kappaB ligand (RANKL). Aqueous ginseng extract produces chromatography peaks characteristic of ginsenosides. Among these peaks, ginsenoside Re is a major component. However, the preventive effects of ginsenoside Re against osteoclast differentiation are not known. We studied the effect of ginsenoside Re on osteoclast differentiation, RANKL induced tartrate-resistant acid phosphatase (TRAP) activity, and formation of multinucleated osteoclasts in vitro...

BACKGROUND: Although everolimus has become a key therapeutic agent in patients with advanced pancreatic neuroendocrine neoplasms (PNEN), its efficacy and safety in clinical practice remains unclear. METHODS: Forty-seven patients with advanced PNEN treated with everolimus were reviewed retrospectively. To evaluate the safety of everolimus as a long-term treatment, the patients were divided into 2 groups according to treatment duration: group A, ≤1 year (n = 21); group B, >1 year (n = 26)...

How Quaternary climatic and geological disturbances influenced the composition of Neotropical forests is hotly debated. Rain fall and temperature changes during and/or immediately after the Last Glacial Maximum (LGM) are thought to have strongly affected the geographical distribution and local abundance of tree species. The paucity of the fossil records in Neotropical forests prevents a direct reconstruction of such processes. To describe community-level historical trends in forest composition, we turned therefore to inferential methods based on the reconstruction of past demographic changes...

BACKGROUND: Guidelines and position papers indicate that allergen immunotherapy (AIT) is the only disease-modifying treatment, including prevention of the onset of new allergen sensitizations. However, this preventive effect was shown by only a few observational studies. Our aim was to systematically review the efficacy of AIT in preventing the onset of new allergen sensitizations. METHODS: Computerized bibliographic searches of MEDLINE, EMBASE, and the Cochrane Library (through June 2015) were supplemented with manual searches of reference lists...

It is necessary for the cell cycle machinery of neurons to be suppressed to promote differentiation and maintenance of their terminally differentiated state. Reactivation of the cell cycle in response to neurotoxic insults leads to neuronal cell death and some cell cycle related proteins contribute to the process. p27 kip1 (p27), an inhibitor of Cyclin Dependent Kinases (CDKs), prevents unwarranted CDK activation. In the present study, we have elucidated a novel mechanism via which p27 promotes apoptosis of neurons stimulated by neurotoxic amyloid peptide Aβ42 (Amyloid β1-42 peptide)...

Malaria remains one of the greatest burdens to global health, causing nearly 500,000 deaths in 2014. When manifesting in the lungs, severe malaria causes acute lung injury/acute respiratory distress syndrome (ALI/ARDS). We have previously shown that a proportion of DBA/2 mice infected with Plasmodium berghei ANKA (PbA) develop ALI/ARDS and that these mice recapitulate various aspects of the human syndrome, such as pulmonary edema, hemorrhaging, pleural effusion and hypoxemia. Herein, we investigated the role of neutrophils in the pathogenesis of malaria-associated ALI/ARDS...

The U.S. Food and Drug Administration (FDA) has long sought to achieve the broader use of personalized medicine, which is better targeting of FDA-approved therapies through incorporating precise knowledge of a patient's underlying condition to therapies optimally chosen to match those needs. While some strides have been made in precision medicine-particularly in oncology and rare genetic diseases-most of the standard general medicine indications have yet to realize the benefits of precision-guided therapies...

The emerging availability of genomic and electronic health data in large populations is a powerful tool for research that has drawn interest in bringing precision medicine to diabetes. In this article, we discuss the potential application of genomics to the prediction, prevention, and treatment of diabetes, and we use examples from other areas of medicine to illustrate some of the challenges involved in conducting genomics research in human populations and implementing findings in practice. At this time, a major barrier to the application of genomics in diabetes care is the lack of actionable genomic findings...

Cytokinesis, the final step of cell division, begins with the formation of a cleavage furrow. How the mitotic spindle specifies the furrow at the equator in animal cells remains unknown. Current models propose that the concentration of the RhoGEF ECT2 at the spindle midzone and the equatorial plasma membrane directs furrow formation. Using chemical genetic and optogenetic tools, we demonstrate that the association of ECT2 with the plasma membrane during anaphase is required and sufficient for cytokinesis. Local membrane targeting of ECT2 leads to unilateral furrowing, highlighting the importance of local ECT2 activity...

We have previously shown that immunization of horses with BPV1 L1 virus-like particles (VLP) is safe and highly immunogenic, and that bovine papillomavirus types 1 and 2 (BPV1, BPV2) are closely related serotypes. Here we evaluated the protective potential of a BPV1 L1 VLP vaccine against experimental BPV1 and BPV2 challenge, and studied the safety and immunogenicity of a bivalent EcPV2/BPV1 L1 VLP vaccine. Fourteen healthy horses were immunized with BPV1 L1 VLPs (100 µg/injection) plus adjuvant on days 0 and 28, whilst seven remained unvaccinated...

AIMS: Oral squamous cell carcinoma (OSCC) prognosis depends on lymph node metastasis (LNM). We recently reported that tumour budding is a good predictive factor for LNM in squamous cell carcinoma of the tongue and floor of the mouth (FOM). Our aim was to evaluate whether tumour budding is a good prognostic factor in OSCC. METHODS AND RESULTS: We examined conventional histopathological assessment and a new factor, tumour budding, in 209 cases of OSCC in incisional biopsy specimens...

Importance: Early-onset major depressive disorder (MDD) is common in individuals at high familial risk of depression and is associated with poor long-term mental health, social, and educational outcomes. Objectives: To examine the developmental pathways that lead to first-episode adolescent-onset MDD (incident cases) in those at high familial risk and to postulate a theoretically informed model that enables simultaneous testing of different pathways to incident adolescent-onset MDD composed of contributions from familial/genetic and social risk factors, as well as effects via specific clinical antecedents...

Chemokines and their G-protein-coupled receptors play a diverse role in immune defence by controlling the migration, activation and survival of immune cells. They are also involved in viral entry, tumour growth and metastasis and hence are important drug targets in a wide range of diseases. Despite very significant efforts by the pharmaceutical industry to develop drugs, with over 50 small-molecule drugs directed at the family entering clinical development, only two compounds have reached the market: maraviroc (CCR5) for HIV infection and plerixafor (CXCR4) for stem-cell mobilization...
