Currently used immunosuppressants exacerbate cardiovascular risk. However, attempts to limit the use of these agents increase the risk of allograft rejection. Immunosuppressants targeting signal 2 and signal 3 lymphocyte activation pathways are under clinical development. Clinical data from trials of the Janus family protein tyrosine kinase-3 inhibitor tasocitinib and the ...

In a screen for senescence-associated genes in Arabidopsis thaliana, a novel, highly up-regulated membrane protein was identified. It is a member of an uncharacterised, strictly plant-specific gene family and was named AtDMP1 (Arabidopsis thaliana DUF679 domain membrane protein 1). The AtDMP proteins are predicted to have four transmembrane spans, with ...

Carcinogenesis is a multi-step process which could be prevented by phytochemicals. Phytochemicals from dietary plants and other plant sources such as herbs are becoming increasingly important sources of anticancer drugs or compounds for cancer chemoprevention or adjuvant chemotherapy. Phytochemicals can prevent cancer initiation, promotion, and progression by exerting anti-inflammatory and ...

Nuclear localization of non-phosphorylated, active beta-catenin is a measure of Wnt pathway activation and is associated with adverse outcome in patients with acute myeloid leukemia (AML). While genetic alterations of the Wnt pathway are infrequent in AML, inhibitors of this pathway are silenced by promoter methylation in other malignanices. Leukemia ...

Death is more than a mere biological occurrence. It has important legal, medical, and social ramifications that make it imperative that those who are responsible for determination of death be accurate and above suspicion. The medical and legal definitions of death have evolved to include consideration of such concepts as ...

The study of aqueous humor dynamics (AHD) in mice is becoming more prevalent as more strains with elevated intraocular pressure (IOP) are developed. High IOP is usually associated with reduced outflow facility making this one of the more important AHD parameters to evaluate. Ocular measurements in mice require anesthesia that ...

Traditional techniques for the insertion of femoral stems in arthroplasty of the hip in osteopetrosis carry a considerable risk of penetration of the femoral cortex and intra-operative fractures, due to obliteration of the intramedullary cavity and greatly increased stiffness and brittleness of the bone. In order to reduce the risk ...

OBJECTIVE: To quantitatively measure workflow and computer use, the activities of 27 medical-surgical RNs were recorded through direct observation. BACKGROUND: Previous studies have shown how nurses spend their time but have not documented the pattern, duration, or frequency of activities. The absence of this information is problematic for leaders charged ...

Cleaning verification is a scientific and economic problem for the pharmaceutical industry. A large amount of potential manufacturing time is lost to the process of cleaning verification. This involves the analysis of residues on spoiled manufacturing equipment, with high-performance liquid chromatography (HPLC) being the predominantly employed analytical technique. The aim ...

To assess the utility of a Worksite Health Promotion Readiness Checklist (WRCL) designed to evaluate the worksite's readiness for implementing health promotion and health protection programs. The WRCL was pilot tested in worksites with (WHPy) and without (WHPn) health promotion programs. The two parts of WRCL scores (observational and administrative) ...

Unlike many other skin diseases, success or failure of therapy of ectoparasitic infestation depends much more on how to use the topical preparation and whom we treat than on which scabicide or pediculicides to use. The diagnosis of scabies should no longer rely on the rather uncommon and unpractical sign ...

Based on analyses in Arabidopsis thaliana ecotype C24, the AtSUC1 protein was previously characterised as a male gametophyte-specific H(+)/sucrose symporter. Later, expression analyses in ecotype Columbia-0 (Col-0) identified AtSUC1 expression also in trichomes (not detected in trichome-less C24 plants) and roots, suggesting ecotype-specific differences in AtSUC1 expression. Here, we present ...

Studies of vitamin D and calcium for fracture prevention have produced inconsistent results, as a result of different vitamin D status and calcium intake at baseline, different doses and poor to adequate compliance. This study tries to define the types of patients, both at risk of osteoporosis and with established ...

A case of a high fibular fracture in association with a triplane fracture in a 12-year-old boy is presented and this unique fracture pattern examined. Whether from blunt trauma or an external rotation mechanism, it appears that trans-syndesmotic fixation is not needed to satisfactorily repair this injury. Because of the ...

The main known function of the pineal gland in humans is the production of melatonin. Benign cysts of the gland have been related to headache, although the mechanism of production of this assumed clinical manifestation has not been clearly determined, due to the lack of large prospective studies. The question ...

Investigate the effect of dietary vitamin E (Vit E) on the retinas of a rat model of induced glaucoma, in which surgically induced elevation of intraocular pressure (IOP) is associated with an increase in reactive oxygen species. Rats were fed a standard chow, Vit E-supplemented diet, or Vit E-deficient diet ...

Hepatitis C virus (HCV) is a common infectious agent and may induce several systemic disorders like mixed cryoglobulinemia. In the geographic areas where HCV infection is hyperendemic, HCV is the predominant etiologic factor for porphyria cutanea tarda and lichen planus. Vasculitides and autoimmune disorders, such as sicca syndrome, are probably ...

Arabidopsis thaliana mutants impaired in starch biosynthesis due to defects in either ADP glucose pyrophosphorylase (adg1-1), plastidic phosphoglucose mutase (pgm) or a new allele of plastidic phosphoglucose isomerase (pgi1-2) exhibit substantial activity of glucose-6-phosphate (Glc6P) transport in leaves that is mediated by a Glc6P/phosphate translocator (GPT) of the inner plastid ...

RNAi-based approaches have contributed significantly to the improved understanding of gene expression and function in vitro. The ability to apply these strategies in vivo to validate the role of specific genes in normal or pathological conditions, and to induce gene silencing, has led to new possibilities for using RNAi as ...

It is important to understand nurses' attitudes toward their work environment. Prior studies in this area have been conducted. The interest was to identify a relative assessment of workplace challenges by studying nurses within developed and developing economies. A representative survey of 2203 nurses in 11 countries was conducted via ...

To determine whether matrix metalloproteinase-7 (MMP-7) that is stably overexpressed by mouse corneal fibroblast cell lines exhibits proteolytic activity against the NC1 fragment of collagen XVIII. Corneal fibroblasts isolated from MMP-7 knockout (7ko) mice were subjected to SV40 T-antigen immortalization and stably transfected with a bicistronic retroviral vector encoding green ...

The crucial differentiation between septic arthritis and transient synovitis of the hip in children can be difficult. In 1999, Kocher et al introduced four clinical predictors which were highly predictive (99.6%) of septic arthritis. These included fever (temperature > or = 38.5 degrees C), inability to bear weight, white blood-cell ...

Although the outcome for advanced stage esophageal cancer is poor, the early detection and treatment of early stage disease is usually associated with a much better outcome. Until recently, esophagectomy has been the treatment of choice in fit patients. However, morbidity is significant, and this has encouraged the development of ...

As systems evolve over time, their natural tendency is to become increasingly more complex. Studies in the field of complex systems have generated new perspectives on management in social organizations such as hospitals. Much of this research appears as a natural extension of the cross-disciplinary field of systems theory. This ...

Rat isolated hearts were perfused in a Langendorff model to study the cardioprotective effects of Bacopa monniera, a medicinal herb used in the Indian system of medicine, on cardiomyocyte apoptosis and antioxidant status following ischaemia-reperfusion (I-R) injury.
