  • This is the first recorded observation of Akashiwo sanguinea excreting mucilaginous substances from pores on the cell surface. Observations were from samples collected in the Caloosahatchee Estuary, Florida, USA during a bloom event, with densities of 672 cells $mL^{-1}$ of A. sanguinea, including 51 cells surrounded by mucous. Scanning electron microscopy observations revealed that the mucous was secreted from thecal pores on the cell surface. The potential significance of mucous production is discussed.

  • This paper describes the application of a wireless data acquisition system to monitor wind pressures and velocities with absolute pressure sensors and an anemometer. The system was developed for future deployment, as part of a research effort currently underway to instrument coastal homes in Florida to monitor roof wind pressures during hurricanes. The proposed wireless system will replace the current system that involves a large amount of hardwired connections from the sensors to the data processing unit that requires labor intensive wiring and preparation of the home. The paper describes comparison studies and field tests to assess the performance of the system. The new system offers the advantages of light hardware, ease of installation, capacity for 48 hours of continuous data acquisition, good frequency and amplitude responses, and a relatively simple maintenance. However, the tests also show that the shape of the shell that has been previously used to protect the sensors might interfere with the proper measurement of the pressures.

  • The aim of this case report is to present a case of 68-year-old male with a history of multiple myeloma and the intravenous use of Zometa (zoledronic acid) who had developed medication-related osteonecrosis of the jaw (MRONJ) following a hot pizza burn to the palate. Clinical and radiographic findings revealed grade 1 MRONJ of the right side of the hard palate. Soft tissue trauma and delayed epithelialization may be associated with some cases of MRONJ. Patients on anti-resorptive medications or anti-angiogenic drugs should be informed of the risk of bone exposure and subsequent MRONJ secondary to physical/chemical insults to the bone and soft tissue in the oral cavity.

  • Project-based joint ventures are often used in the construction industry to assemble an organization that meets a client's project needs and matches or exceeds the capacities of competitors. The joint venture / partnerships provides the means for a firm to quickly add resource, political, technical, or other required strengths that will increase project acquisition. This paper sets out to study the types of joint ventures, different issues or problems while having joint ventures and the critical factors that contribute to successful joint ventures. A questionnaire was designed and administered to survey the issues and present practices of joint ventures in the South Florida construction industry. Along with the questionnaire, personnel interviews were also conducted to get first hand knowledge about the subject matter. The results are presented in the paper. These results specifically identify the overall practice of joint ventures in South Florida as well as indicate the most significant factors leading to failure or success of these ventures.

  • No-flow ischemia occurs during cardiac arrest, hemorrhagic shock, liver resection and transplantation. Recovery of blood flow and normal physiological pH, however, irreversibly injures the liver and other tissues. Although the liver has the powerful machinery for mitochondrial quality control, a process called mitophagy, mitochondrial dysfunction and subsequent cell death occur after reperfusion. Growing evidence indicates that reperfusion impairs mitophagy, leading to mitochondrial dysfunction, defective oxidative phosphorylation, accumulation of toxic metabolites, energy loss and ultimately cell death. The importance of acetylation/deacetylation cycle in the mitochondria and mitophagy has recently gained attention. Emerging data suggest that sirtuins, enzymes deacetylating a variety of target proteins in cellular metabolism, survival and longevity, may also act as an autophagy modulator. This review highlights recent advances of our understanding of a mechanistic correlation between sirtuin 1, mitophagy and ischemic liver injury.

Evaluaton of the Government Recommended Forage Cultivars in Korea V. Forage performance and quality of Italian ryegrass cultivars (목초 및 사료작물 정부장려품종의 지역적응성 평가 V. 이탈리안 라이그라스의 사초수량과 사료가치)

  • Twelve Italian ryegrass (Lolium mult~flomm L.) cultivars have recommended as the government recommended forage cultivars since 1984, however, the forage performance and quality have been mostly tested at two locations, such as Suweon and Sunghwan in the Middle Northwestern and Middle Southwestern Coast Regions, respectively. Therefore, the objective of this experiment was to retest the forage performance and quality of already recommended twelve government Italian ryegrass cultivars at five scattered locations, such as Icheon, Suweon, Sunghwan, Keon- and Kwangju from 1992 to 1995 with the intention of improving recommendations to dairy farmers. Cultivars with more dry matter yield than the control 'Tetrone' were 'Tosca' , 'Bartissimo' , 'Florida 80' and 'Gordo' in the Middle Northwestern Coast Region ; 'Tosca' , 'Florida 80' , 'Bartissimo' , 'Wencke' and 'Gordo' in the Middle Southwestern Coast Region ; 'Tosca' , 'Florida 80' , 'Sikem' , 'Bartissimo' , 'Wencke' and 'Gordo' in the Keongbuk Inland Region; 'Florida 80', 'Tosca' , 'Barmultra' and 'Bartissimo' in the Southern Inland Region and 'Florida 80' , 'Gordo' , 'Sikem' , 'Bartissimo' and 'Tosca' in the Southern Coast Region. At all the locations in 1992-95, 'Florida 80' produced the highest forage yield and showed earliness, but this cultivar was less cold tolerant in the Middle Northwestern and Middle Southwestern Coast Regions and grew tall which made it vulnerable to lodging in all the exprimental regions except the Southern Coast. Differences among the ryegrass cultivars for the three year mean ADF and NDF were small and inconsistent.
