A Histochemical and Fine Structural Study of Extracellular Fibrils in the Developing Chick Embryo

The histochemistry of developing connective tissues and its relation to early connective tissue fibrils was investigated in the chick embryo. An area well suited to correlated histochemical and electron microscopic study occurs around the notochord. Here early microfibrils later contribute to the cartilaginous model of the future vertebral body. Chick embryos were sacrificed at one, two, three, four, six and ten days of incubation and were prepared routinely for both light and electron microscopy. A series of five histochemical stains (PAS, alcian blue, Hale colloidal iron, metachromatic toluidine blue, methenamine silver) and two histological techniques (Mallory\u27s connective tissue; Weigert\u27s elastin) was used for the light microscopic demonstration of polysaccharides, mucoproteins, mucopolysaccharides and mature connective tissue elements. The first positive response for all histochemical stains occurs on the third day of incubation. Moderate microfibrillar growth in electron microscopy precedes this by one day. At this time light microscopic staining patterns differ from electron microscopic fibrillar arrangements. By the sixth day, dense microfibrillar concentrations appear in the precartilage area where acid mucopolysaccharides are intensely concentrated. Staining for mature connective tissue fibrils does not occur until the tenth day. Polysaccharides, mucoproteins and mucopolysaccharides are interfibrillar components that are closely associated with the early stages of fibrillogenesis. Microfibrils become intensely concentrated in a matrix of these substances. Here, the future cartilaginous model with its heavy population of unit collagen fibrils will form

Storing High Moisture Grain

For the past several years there has been increased interest in the harvesting and storing of high-moisture feed grains, particularly corn, barley and grain sorghum. With improved silos and grain harvesting equipment, the use of high-moisture grains has replaced the conventional methods of harvesting, storing and feeding grains on many cattle feeding farms. There are several reasons why this system is becoming more popular. Harvesting can be done earlier and faster, harvesting losses are reduced, and a minimum number of operations and amount of equipment are required. Storage costs are comparatively low and in most cases storage is rodent free. It is adaptable to mechanical feeding and storage losses are low when good structures and good management are used

2017 Commencement Address: Dr. James J. O\u27Connell

Dr. James J. O’Connell, president and founding physician of the Boston Health Care for the Homeless Program (BHCHP) and assistant professor of medicine at Harvard Medical School, will receive an honorary degree from the College of the Holy Cross and address this year’s graduates during the College’s Commencement ceremonies on Friday, May 26, at 10:30 a.m. at the DCU Center in Worcester. Dr. O’Connell has dedicated his medical career to caring for Boston’s homeless. His leadership has contributed to the growth of the BHCHP since its founding in 1985 to become the country’s largest and most comprehensive program of its kind, serving more than 12,000 homeless people a year in two hospital-based clinics and more than 60 shelters and outreach sites. Throughout his 30 years at the helm, Dr. O’Connell has continued to serve on the team of doctors that meets patients on the streets, offering food and warm socks, medical treatment and the support of trusted friends. Dr. O’Connell served as the National Program Director of the Homeless Families Program of the Robert Wood Johnson Foundation and the U.S. Department of Housing and Urban Development from 1989–1996. In addition to publishing articles in the New England Journal of Medicine, Journal of the American Medical Association, Circulation, American Journal of Public Health and Journal of Clinical Ethics, he is the editor of “The Health Care of Homeless Persons: A Manual of Communicable Diseases and Common Problems in Shelters and on the Streets” (BHCHP Press, 2004). He published his first book, “Stories from the Shadows: Reflections of a Street Doctor” (BHCHP Press), in 2015. The recipient of numerous awards, including the Albert Schweitzer Humanitarian Award in 2012 and the Trustees’ Medal at the bicentennial celebration of Massachusetts General Hospital in 2011, Dr. O’Connell is a graduate of the University of Notre Dame, Cambridge University and Harvard Medical School.https://crossworks.holycross.edu/commence_address/1003/thumbnail.jp

Public School Prayer and the First Amendment: Reconciling Constitutional Claims

has been consistently held to bar any form of prayer or devotional exercise in public schools, at least when prescribed by law, and frequently also when initiated by students. The author examines the two principal Supreme Court decisions that have produced this constitutional doctrine, and the manner in which other courts have both followed and expanded on these rulings. The author concludes, however, that the absolute outlawing of all religious expression by public school students is not a logically necessary result, and observes an emerging trend of free exercise and free expression based upon the first amendment

AIDS and the Homeless of Boston

Homeless persons with AIDS and HIV infection face significant health hazards during the daily struggle for survival on the streets and in the crowded shelters of our cities. This article offers a historical perspective on the evolution of the AIDS epidemic within the homeless population of Boston and examines the demographics, risk behaviors, and survival statistics of that epidemic. The Boston Health Care for the Homeless Program is presented as a model of service delivery that offers quality health care to homeless persons with AIDS while addressing the special needs of those bound by the immediacy of the next meal and a night\u27s shelter. Health care is inextricably woven into the fabric of social policy and cannot be delivered without an accessible network of housing, entitlement, job training, mental health, and substance-abuse services

Evidence of Spawning Capable Tarpon (Megalops atlanticus) Off the Louisiana Coast

Despite the fact that the tarpon (Megalops atlanticus) is a popular sport fish in the Gulf of Mexico (GOM; Ault et al. 2008), little is known of its spawning behavior. Spawning M. atlanticus have never been documented and fertilized eggs have not been observed in situ (Ault et al. 2008). While it has been suggested that adult M. atlanticus move to deep water off the southwest coast of Florida and into the Yucatan Channel to spawn, the actual locations of spawning grounds remain unknown (Smith 1980, Crabtree et al. 1995, Crabtree et al. 1997). Distribution patterns of larvae (leptocephali) have served as the basis for most of what has been inferred about the spawning areas (Smith 1980, Crabtree et al. 1997). For example, leptocephali were collected from the southwestern GOM, the Yucatan Channel, and along the west coast of Florida, and based on the their size, it was assumed that M. atlanticus spawned in nearby areas (Smith 1980). Histological examination of gonads has also been used to estimate the location of M. atlanticus spawning habitat. Females collected from the Florida Keys and Boca Grande Pass off the west coast of Florida and contained ovaries with post ovulatory follicles (POF) and advanced vitellogenic oocytes, suggesting M. atlanticus spawn in this region from April through July (Crabtree et al. 1997). Examination of gonads from M. atlanticus caught off the coast of equatorial Ceara State, Brazil suggested that spawning occurs there from October through January (de Menezes and Paiva 1966). We report here the first evidence of spawning capable M. atlanticus off the coast of Louisiana in the northern GOM based on histological examination of gonads
