Recovery from training: a brief review: brief review

Athletes spend a much greater proportion of their time recovering than they do in training. Yet, much attention has been given to training with very little investigation of recovery. The purpose of this review is to stimulate further research into this vital area of training. Recovery can be categorized in three terms: i) immediate recovery between exertions; ii) short-term recovery between repeats (e.g., between resistance sets or interval bouts); and iii) training recovery between workouts. The focus of this review is training recovery. Full training recovery is essential to optimal performance and improvement. This review includes an examination of extant research on recovery and a very brief review of some potential modalities and techniques for hastening recovery and the time course of recovery and responses to some treatments. Measures of recovery and practical considerations are discussed briefly. Much research is needed in this area, but there are obstacles to high quality research. Attention must be given to key issues in research on recovery, especially the individual response to recovery treatments.     

Edwardsiellosis in fish: a brief review

Edwardsiellosis is one of the most important bacterial diseases in fish. Scientific work on this disease started more than forty years ago and numerous workers around the world are continually adding to the knowledge of the disease. In spite of this, not a single article that reviews the enormous scientific data thus generated is available in the English language. This article briefly discusses some of the recent research on edwardsiellosis, describing the pathogen’s interaction with the host and environment, its pathogenesis and pathology as well as diagnostic, preventive and control measures.

A brief review

This article serves as a brief history and review of EBM—how EBM developed, its strengths and limitations, and the need for constant improvements. Hopefully, this review will have enhanced your understanding of EBM and its importance and stimulated you to apply EBM to your own practice. As more data and therapies become available, and as clinical guidelines continue to evolve based on EBM, we should expect patient outcomes to improve.     

Viruses in type 1 diabetes: brief review

Type 1 diabetes results from the progressive destruction of insulin-producing pancreatic beta cells. Although the etiology of type 1 diabetes is believed to have a major genetic component, studies on the risk of developing type 1 diabetes suggest that environmental factors, such as viruses, may be important etiological determinants. Among the viruses, the most clear and unequivocal evidence that a virus induces type 1 diabetes in animals comes from studies on the D variant of encephalomyocarditis (EMC-D) virus in mice and Kilham rat virus (KRV) in rats. A high titer of EMC-D viral infection results in the development of diabetes within 3 days, primarily due to the rapid destruction of beta cells by viral replication within the cells. A low titer of EMC-D viral infection results in the recruitment of macrophages to the islets. Soluble mediators produced by the activated macrophages such as interleukin-1Beta, tumor necrosis factor-alpha, and nitric oxide play a critical role in the destruction of residual beta cells. KRV causes autoimmune type 1 diabetes in diabetes resistant-BioBreeding rats by breakdown of immune balance, including the preferential activation of effector T cells, such as Th1-like CD45RC+CD4+ T cells and CD8+ T cells, and down-regulation of Th2-like CD45RC-CD4+ and CD4+CD25+ T cells, rather than by direct infection of pancreatic beta cells.     

Cellular calcium and atherosclerosis: A brief review

Evidence for and against the theory that cell calcium is causally involved in the pathogenesis of atherosclerosis is presented and evaluated. In particular, it is argued that: (1) arterial calcium is increased in atherosclerosis; (2) this increase in tissue calcium content is largely intracellular; (3) this increased intracellular calcium content is caused by increased plasma membrane calcium permeability; (4) the increased calcium content is causally related to atherogenesis; (5) many of the cell physiological, cell biological, biochemical, and molecular biological processes, known to function abnormally in atherosclerosis, are also known to be calcium regulated; and (6) these processes are activated or inactivated in atherosclerosis in a manner consistent with increased cell calcium. It is concluded that the calcium-atherogenesis hypothesis has the potential to unify macroscopic clinical risk factors in terms of intracellular mechanisms that are controlled by cell calcium, and that this hypothesis deserves further experimental tests.     

Insulin and endothelial function: A brief review

Background: In recent years, the novel effects of insulin beyond control of glucose metabolism have been appreciated, especially those that impact vascular function. A better understanding of insulin's protective interactions with the endothelium has provided clinicians with a justification for more aggressive use of insulin—not only to control glucose levels, but also to potentially reduce the progression of atherosclerosis and its pathogenic sequelae.Objective: In this brief review, we provide a snapshot of the available research and clinical findings signifying beneficial effects of insulin on the endothelium.Methods: We conducted a MEDLINE search of articles published in English from 1965 through 2007 using the search terms insulin, endothelium, and anti-inflammatory. Articles with a focus on “insulin resistance” per se were excluded from this review.Results: The literature search identified 200 articles that addressed the effects of insulin on endothelium and the interaction between insulin and the vasculature.Conclusions: In addition to mitigating hyperglycemic toxicity, insulin has multiple beneficial interactions with the endothelium in physiologic and disease states. The anti-inflammatory actions of insulin confer beneficial effects in preventing and minimizing morbidity and mortality due to atherosclerosis, especially in acute settings like myocardial infarction.     

Hidrocystomas--a brief review

Hidrocystomas, eccrine and apocrine, are rare cystic lesions that form benign tumors of the sweat glands. In this clinical review, we present a "classic" case of hidrocystoma and review the main epidemiologic, histologic, and clinical features. We also review the effectiveness of experimental treatment methods and present information about associated syndromes and differential diagnosis, focusing especially on hidrocystomas' resemblance to basal cell carcinoma.     

Coral growth and reef growth: a brief review

The growth potential of modern zooxanthellate corals from the major reef provinces is reviewed with respect to Holocene reef growth. Both coral growth and reef growth is enhanced globally at the beginning of the Holocene and is maintained regionally in the Caribbean Sea up to the present in contrast to reefs of the Indo-Pacific Ocean. This regional difference is mainly caused by the siphoning effect of the tropical Atlantic, which is characterised still by a rising sea level in contrast to global ocean. Hence, Indo-Pacific reefs exhibit a well-cemented reef crest and reef roof barren of living corals. The evaluation of reef growth rates throughout the Phanerozoic shows reduced growth rates of more than one order of magnitude in comparison to their modern counterparts. This is a result of compaction and diagenesis but also strongly biased by uncertainties in absolute dating. Point counting of individual framebuilders with known growth rate may result in more comparative figures for growth rates of fossil reefs with respect to modern ones.     

Extracellular signals and pancreatic beta-cell development: a brief review

Cell lineage development is a finely tuned process of proliferation and differentiation, survival and apoptosis, that is regulated by numerous extracellular signals. Here we review some of the extracellular signals--including insoluble cell-cell and extracellular matrix-cell interactions, as well as soluble factors--that appear critical for pancreatic beta-cell development. Knowledge of how these signals control the development of pancreatic endocrine stem/precursor cells into fully functional insulin-secreting beta cells is a platform for the restoration of beta-cell function and the cure therapy of type 1 diabetes.

Postactivation potentiation and its practical applicability: a brief review

It has been suggested that postactivation potentiation (PAP) may be manipulated to enhance both acute performance and chronic adaptation. PAP refers to the phenomenon by which acute muscle force output is enhanced as a result of contractile history. Evidence exists regarding the existence of PAP. However, the determination of methods to best manipulate and exploit PAP remains elusive. Studies to date would seem to indicate that the practical applicability of PAP in terms of enhancing athletic performance is limited.
