Biogeochemical ecology of six species of Sphagnum in Costa Rica

There is very little information on the biogeochemical ecology of Sphagnum species in tropical regions. The majority of the ecological information on Sphagnum species in the tropics consists of general habitat information and pH values that are reported in new species descriptions and regional floras such as those of Crum (1980, 1989), Crum and Buck (1988), Karlin (1991), and McQueen (1989)

Meeting the protein and amino acid needs of swine (1982)

All pigs require protein, which consists of amino acids. Amino acids are used for maintenance, growth, gestation, and lactation. Pigs actually do not have a protein requirement, but quality protein provides the amino acids which are required. While some amino acids are synthesized by the animal, the essential ones cannot be synthesized at a rapid enough rate to permit normal growth. These must be provided in the feed

Preventing sulfa residues in pork (1993)

Sulfa products and other antibiotics have been widely used in Missouri's swine industry for promoting growth and for reducing disease problems and death in pigs. The benefits of antibiotics, including sulfa, are based on research trials. They are regulated through the amount you add to rations and through the levels inspectors accept as residues in meat tissue. In recent years, the pork industry and governmental agencies have become concerned about the number of hogs going to market with illegal levels of sulfa in their tissue

Care of pigs from farrowing to weaning (1993)

The most critical period in the life cycle of a pig is from birth to weaning. On the average, about two pigs per litter are lost during this period. Poor management is the major contributing factor, although the actual cause may be crushing, bleeding from the navel, anemia, starvation or disease. Weaning large litters of thrifty, heavyweight pigs is a key factor for a profitable swine herd. This publication attempts to outline management practices that help keep pigs alive and profits high

Evolving librarian participation in a specialized primary care medical education program

Objectives: To describe the extent to which health sciences librarians are embedded into a program that gives medical students focused experiences in underserved international, rural, or inner city primary care settings. Methods: Since 2009, librarians at a large urban research university have worked with a longitudinal program that gives medical students focused education and experience in underserved international, rural, or inner city primary care settings. Initially, the library offered a meeting space for the program and librarians led a class on library resources prior to students beginning work on a required capstone projects. Librarians cultivated relationships with faculty and students through interactions in classes and in individual consultations. As the program matured and its needs changed, librarians offered services and expertise to match the growth of the curriculum. Results: Librarians currently co-teach two capstone training sessions for third year medical students, which has progressed from a basic orientation on library resources and searching to in-depth instructions on literature reviews and leading small group discussions on student capstone projects. As a result of these sessions, librarians hold regular consultations with students at various stages of the projects to train them in library resources and assist them in conducting literature reviews. A librarian also met with faculty to revise, and subsequently co-teach, a journal club for first and second year students focusing on issues health care in underserved populations and critical appraisal of research literature. More recently, a librarian was asked to serve as part of an interdisciplinary panel that reviews student capstone project proposals. Conclusions: Over the past several years, librarians have taken on increasingly complex roles in a small specialized program within a school of medicine. Through regular contact with faculty and students and a willingness to participate at any level of the program, librarians have moved well past teaching one-shot sessions to being fully embedded in the program

Delayed phlegmon with gallstone fragments masquerading as soft tissue sarcoma.

Complications from lost gallstones after cholecystectomy are rare but varied from simple perihepatic abscess to empyema and expectoration of gallstones. Gallstone complications have been reported in nearly every organ system, although reports of malignant masquerade of retained gallstones are few. We present the case of an 87-year-old woman with a flank soft tissue tumor 4 years after laparoscopic cholecystectomy. The initial clinical, radiographic and biopsy findings were consistent with soft tissue sarcoma (STS), but careful review of her case in multidisciplinary conference raised the suspicion for retained gallstones rather than STS. The patient was treated with incisional biopsy/drainage of the mass, and gallstones were retrieved. The patient recovered completely without an extensive resectional procedure, emphasizing the importance of multidisciplinary sarcoma care to optimize outcomes for potential sarcoma patients

Managing purchased feeder pigs (1993)

Missouri is a major feeder pig producing state and annually markets large numbers of pigs that other farmers feed out to market weight. During these marketing and transportation processes, stress can affect the performance of feeder pigs. Buyers often complain of recently purchased pigs that cough, scour or die. Pigs that are slow to start growing and that have poor feed efficiency also may be a problem. This publication recommends procedures for buying, feeding and managing purchased feeder pigs
