This study aimed to investigate the frequency of anti-Toxoplasma gondii antibodies in serum from 629 chickens on 39 family farms in seven municipalities in the semiarid region, Pernambuco, Brazil, and to identify risk factors associated with T. gondii infection. The risk factors were studied in 421 samples from 29 farms. Anti-T. gondii antibodies were investigated by indirect fluorescent antibo...

Background. Patients with sepsis benefit from early diagnosis and treatment. Accurate paramedic recognition of sepsis is important to initiate care promptly for patients who arrive by Emergency Medical Services. Methods. Prospective observational study of adult patients (age ≥ 16 years) transported by paramedics to the emergency department (ED) of a Canadian tertiary hospital. Paramedic identif...

Protocols and checklists have been shown to reduce patient harm through improved standardization and communication. Implementation of protocols and guidelines often is delayed because of lack of health care provider awareness or difficult clinical algorithms in medical institutions. However, the use of checklists and protocols clearly has been demonstrated to improve outcomes and their use is s...

teractions produced by the optical triggers are insufficient to do this. These optical triggers do, however, provide a unique opportunity to investigate the nanosecondmicrosecond dynamics of the unfolded protein prior to surmounting the free energy barrier that separates the unfolded structures from the native state (9).

Although the solutions with respect to time are commonly sought when analyzing the behavior of dynamic systems, there are other expressions that can be as revealing and important. Specifically, motion constants, which are time independent algebraic or transcendental equations involving the system states, can provide a broad view of a system’s motion. Locally, at least, the motion constants of a...

The protein tyrosine phosphatases (PTPs) IA-2 and phogrin (IA-2beta) are major autoantigens in type 1 diabetes that possess common serological epitopes in their COOH termini. The epitopes recognized by the T-cells that cause the disease, however, remain to be defined. Eight phogrin-specific T-cell clones were generated from NOD mice, and their epitopes were mapped. The mapping was performed ini...

I N T R O D U C T I O N It is generally accepted that glial cells provide mechanical and, perhaps, metabol ic support for the neuronal cells that they surround but do not par t ic ipate directly in the events of excitabil i ty (Nakai, 1963; Kuff ler and Nicholls, 1966). However, in 1976 Villegas et al. (1976) reported electrophysiological evidence for the existence of sodium channels in Schwann...
