The Central Nervous System

In recent years, we have learned that adipocytes are not merely inert storage depots for triglycerides but rather highly active cells with potent autocrine, paracrine and endocrine functions. Adipose tissue secretes a large number of physiologically active polypeptides. Although leptin remains one of the best-studied examples of an adipocyte-specific secretory factor, recent reports describe potent physiological activities for another adipocyte-specific secreted protein, adipocyte complement-related protein of 30 kDa (Acrp30). Full-length versions of Acrp30 or its proteolytic fragments decrease the postprandial rise of plasma free fatty acids and improve postabsorptive insulin-mediated suppression of hepatic glucose output. A strong correlation between plasma Acrp30 levels and systemic insulin sensitivity is well established and the protein has putative anti-atherogenic properties that are relevant for the prevention of formation of atherosclerotic plaques. The current challenge is to understand the molecular mechanisms through which the protein exerts its multiple functions.

ACRP30/adiponectin: an adipokine regulating glucose and lipid metabolism

BACKGROUND: Treatment of cancer is increasingly more effective but is associated with short and long term side effects. Oral side effects remain a major source of illness despite the use of a variety of agents to prevent them. One of these side effects is oral mucositis (mouth ulcers). OBJECTIVES: To evaluate the effectiveness of prophylactic agents for oral mucositis in patients with cancer receiving treatment, compared with other potentially active interventions, placebo or no treatment. SEARCH STRATEGY: Electronic searches of Cochrane Oral Health Group and PaPaS Trials Registers (to 16 February 2011), CENTRAL (The Cochrane Library 2011, Issue 1), MEDLINE via OVID (1950 to 16 February 2011), EMBASE via OVID (1980 to 16 February 2011), CINAHL via EBSCO (1980 to 16 February 2011), CANCERLIT via PubMed (1950 to 16 February 2011), OpenSIGLE (1980 to 2005) and LILACS via the Virtual Health Library (1980 to 16 February 2011) were undertaken. Reference lists from relevant articles were searched and the authors of eligible trials were contacted to identify trials and obtain additional information. SELECTION CRITERIA: Randomised controlled trials of interventions to prevent oral mucositis in patients receiving treatment for cancer. DATA COLLECTION AND ANALYSIS: Information regarding methods, participants, interventions, outcome measures, results and risk of bias were independently extracted, in duplicate, by two review authors. Authors were contacted for further details where these were unclear. The Cochrane Collaboration statistical guidelines were followed and risk ratios calculated using random-effects models. MAIN RESULTS: A total of 131 studies with 10,514 randomised participants are now included. Overall only 8% of these studies were assessed as being at low risk of bias. Ten interventions, where there was more than one trial in the meta-analysis, showed some statistically significant evidence of a benefit (albeit sometimes weak) for either preventing or reducing the severity of mucositis, compared to either a placebo or no treatment. These ten interventions were: aloe vera, amifostine, cryotherapy, granulocyte-colony stimulating factor (G-CSF), intravenous glutamine, honey, keratinocyte growth factor, laser, polymixin/tobramycin/amphotericin (PTA) antibiotic pastille/paste and sucralfate. AUTHORS' CONCLUSIONS: Ten interventions were found to have some benefit with regard to preventing or reducing the severity of mucositis associated with cancer treatment. The strength of the evidence was variable and implications for practice include consideration that benefits may be specific for certain cancer types and treatment. There is a need for further well designed, and conducted trials with sufficient numbers of participants to perform subgroup analyses by type of disease and chemotherapeutic agent.

C1q and tumor necrosis factor superfamily: modularity and versatility.

Biochemical, genetic, and animal studies in recent years have established a critical role for the adipokine Acrp30/adiponectin in controlling whole-body metabolism, particularly by enhancing insulin sensitivity in muscle and liver, and by increasing fatty acid oxidation in muscle. We describe a widely expressed and highly conserved family of adiponectin paralogs designated as C1q/tumor necrosis factor-alpha-related proteins (CTRPs) 1-7. In the present study, we focus on mCTRP2, the mouse paralog most similar to adiponectin. At nanomolar concentrations, bacterially produced mCTRP2 rapidly induced phosphorylation of AMP-activated protein kinase, acetyl-CoA carboxylase, and mitogen-activated protein kinase in C2C12 myotubes, which resulted in increased glycogen accumulation and fatty acid oxidation. The discovery of a family of adiponectin paralogs has implications for understanding the control of energy homeostasis and could provide new targets for pharmacologic intervention in metabolic diseases such as diabetes and obesity.

Purpose: Oral tongue carcinomas are highly curable with radiotherapy. In the past, patients with tongue carcinoma have usually been treated with low dose rate (LDR) interstitial radiation. This Phase III study was designed to compare the treatment results obtained with LDR with those obtained with high dose rate (HDR) interstitial radiotherapy for tongue carcinoma. Methods and Materials: The criteria for patient selection for the Phase III study were: (a) presence of a T1T2N0 tumor that could be treated with single-plane implantation, (b) localization of tumor at the lateral tongue border, (c) tumor thickness of 10 mm or less, (d) performance status between O and 3, and (e) absence of any severe concurrent disease. From April 1992 through December 1993, 15 patients in the LDR group (70 Gy/4 to 9 days) and 14 patients in the HDR group (60 Gy/10 fractions/6 days) were accrued. The time interval between two fractions of the HDR brachytherapy was more than 6 h. Results: Local recurrence occurred in two patients treated with LDR brachytherapy but in none of the patients treated with HDR. One- and 2-year local control rates for patients in the LDR group were both 86%, compared with 100% in the HDR group ( p = 0.157). There were four patients with nodal metastasis in the LDR group and three in the HDR group. Local recurrence occurred in two of the four patients with nodal metastases in the LDR group. One- and 2-year nodal control rates for patients in LDR group are were 85, compared with 79% in the HDR group. Conclusion: HDR fractionated interstitial brachytherapy can be an alternative to traditional LDR brachytherapy for early tongue cancer and eliminate the radiation exposure for medical staffs.

Objective. The purpose of this study is to examine the correlation between histopathologic and radiographic findings and to discuss the cause of the simple bone cyst. Study design. Histopathologically, we classified 53 simple bone cysts into two types. Type A has a connective tissue membrane and type B has a partially thickened wall with dysplastic bone formation. Radiographically, we evaluated the following: margin, radiolucency, or radiopacity, relationship with tooth apices, bucco-lingual bone expansion, and displacement of the mandibular canal. Results. Bone expansion and radiopacity were closely related to histopathologic findings although there was no correlation between the histopathologic findings and radiographic margin, relationship with tooth apices, and displacement of mandibular canal. Local recurrence was more likely to be observed in patients diagnosed as having type B than type A lesions. Conclusions. Type A and type B bone cysts may have different causes. Cysts determined radiographically to be radiopaque, those diagnosed as type B histopathologically, and cysts that have been treated surgically should all be followed by radiographic examinations.

CTRP3/cartducin, a novel secretory protein, is a member of the C1q and tumor necrosis factor (TNF)-related protein (CTRP) superfamily. CTRP3/cartducin gene is transiently up-regulated in a balloon-injured rat carotid artery tissue. In this study, we report a new function of CTRP3/cartducin as a regulator of angiogenic processes. CTRP3/cartducin promoted proliferation and migration of mouse endothelial MSS31 cells in a dose-dependent manner. Further, stimulation of MSS31 by CTRP3/cartducin led to activation of extracellular signal-regulated kinase 1/2 (ERK1/2) and p38 mitogen-activated protein kinase (MAPK). MAPK/ERK kinase 1/2 (MEK1/2) inhibitor, U0126, and p38 MAPK inhibitor, SB203580, blocked the CTRP3/cartducin-induced cell proliferation, and migration was blocked by U0126, but not the SB203580. Taken together, these results suggest that CTRP3/cartducin may be involved as a novel angiogenic factor in the formation of neointima following angioplasty.
