Environmental assessment of Dermatophagoides mite‐allergen levels in Sweden should include Der m 1
Authors: A. Warner, S. Boström, A. K. M. Munir, C. Möller, C. Schou, N.‐I. M. Kjellman
Journal: Allergy (1998)

The major allergen of Dermatophagoides microceras , Der m 1, as well as the allergens of D. pteronyssinus and D. farinae , Der p 1 and Der f 1, were analyzed in the homes of 111 asthmatic children in three climatic regions in Sweden. TTie numbers and species of mites were determined by microscopy, and circulating IgE antibodies against mites were measured. Der f 1 was the predominant house‐dust‐mite (HDM) allergen, Der p 1 the least often found, and Der m 1 represented 31% of the allergen load. However, in the Linkoping area, Der m 1 was the major HDM allergen (58%). Mite counts and allergen levels correlated well. Current exposure to HDM allergens at home was associated with the serum IgE antibody response to HDM in the children with no threshold level. Of the ehildren with IgE antibodies against HDM, 67% reacted to all three mites. Mite sensitization rates were marginally increased (7%) by the addition of IgE analysis of D. microceras to the routine analysis of IgE antibodies against D. pteronyssinus and D. farinae . Thus, Der m 1 may be an important HDM allergen and should be considered when HDM exposure data are assessed in areas with a climate like that of Sweden.

Modulation of lipoprotein lipase activity by apolipoproteins. Effect of apolipoprotein C-III.
Authors: C S Wang, W J McConathy, H U Kloer, P Alaupovic
Journal: Journal of Clinical Investigation (1985)

From a total of 22 hypertriglyceridemic subjects tested, 14 subjects were selected on the basis of normal postheparin plasma lipoprotein lipase (LPL) levels and the presence of LPL inhibitory activity in their fasting plasma. The inhibitory activity was detected in both the lipoprotein fraction (d less than 1.25 g/ml) and the lipoprotein-deficient fraction (d greater than 1.25 g/ml). Correlational analyses of LPL inhibitory activity and apolipoprotein levels present in the lipoprotein fraction (d less than 1.25 g/ml) indicated that only apolipoprotein C-III (ApoC-III) was significantly correlated (r = 0.602, P less than 0.05) with the inhibition activity of the lipoprotein fraction. Furthermore, it was found that LPL-inhibitory activities of the plasma lipoprotein fraction and lipoprotein-deficient fraction were also correlated (r = 0.745, P less than 0.005), though the activity in the lipoprotein-deficient plasma was not related to the ApoC-III or apolipoprotein E levels. Additional correlational analyses indicated that the LPL levels in the postheparin plasma of these subjects were inversely related to the levels of plasma apolipoproteins C-II, C-III, and E. To explain some of these observations, we directly examined the in vitro effect of ApoC-III on LPL activity. The addition of ApoC-III-2 resulted in a decreased rate of lipolysis of human very low density lipoproteins by LPL. Kinetic analyses indicated that ApoC-III-2 was a noncompetitive inhibitor of LPL suggesting a direct interaction of the inhibitor with LPL. Results of these studies suggest that ApoC-III may represent a physiologic modulator of LPL activity levels and that the incidence of LPL inhibitory activity in the plasma of hypertriglyceridemic subjects is more common than previously recognized.
Down-regulation of Mammalian Sterile 20–Like Kinase 1 by Heat Shock Protein 70 Mediates Cisplatin Resistance in Prostate Cancer Cells
Authors: Aixia Ren, Guijun Yan, Bei You, Jianxin Sun
Journal: Cancer Research (2008)

Abstract Mammalian sterile 20–like kinase 1 (Mst1) is an ubiquitously expressed serine/threonine kinase, and its activation results in cell apoptosis. Recent studies suggest that Mst1 may function as a tumor suppressor. Here, we reported that heat shock protein 70 (Hsp70), which is thought to protect cells against cellular stress, has been identified as an Mst1-interacting protein, in a yeast two-hybrid screen of human adult prostate cDNA library with a dominant-negative Mst1 (K59R) as bait. The interaction of Mst1 with Hsp70 was confirmed by coimmunoprecipitation in both cotransfected HEK293 cells and prostate cancer cells. Hsp70 colocalized with Mst1 in the cytoplasm of LNCaP cells. The interaction sites with Mst1 consisted of NH2-terminal ATPase domain in Hsp70, whereas the inhibitory domain of Mst1 mediates the binding of Hsp70 in Mst1. Overexpression of Hsp70 mediates proteasomal degradation of Mst1 in a Hsp70 interacting protein (CHIP)-dependent manner. Furthermore, the proapoptotic effect of Mst1 was markedly inhibited by overexpression of Hsp70 or CHIP. Most strikingly, in response to the treatment of anticancer drug cisplatin, the induction of Hsp70 expression is higher in the androgen-independent DU145 cells compared with the androgen-dependent LNCaP cells. The higher levels of Hsp70 induction and subsequent Mst1 degradation mediate cisplatin resistance in prostate cancer DU145 cells. Moreover, overexpression of Mst1 sensitizes prostate cancer cells to cisplatin treatment. These findings implicate that Mst1, a downstream target of Hsp70, may be developed as a target for sensitizing hormone-refractory prostate cancers to chemotherapy. [Cancer Res 2008;68(7):2266–74]

To establish the clinical relevance of proprioceptive deficits reported after anterior cruciate ligament (ACL) injury.A literature search was done in electronic databases from January 1990 to June 2009. Inclusion criteria for studies were ACL deficient (ACL-D) and ACL reconstruction (ACL-R) articles written in English, Dutch or German and calculation of correlation(s) between proprioception tests and clinical outcome measures. Clinical outcome measures were muscle strength, laxity, hop test, balance, patient-reported outcome, objective knee score rating, patient satisfaction or return to sports. Studies included in the review were assessed on their methodological quality.In total 1161 studies were identified of which 24 met the inclusion criteria. Pooling of all data was not possible due to substantial differences in measurement techniques and data analysis. Most studies failed to perform reliability measurements of the test device used. In general, the correlation between proprioception and laxity, balance, hop tests and patient outcome was low. Four studies reported a moderate correlation between proprioception, strength, balance or hop test.There is limited evidence that proprioceptive deficits as detected by commonly used tests adversely affect function in ACL-D and ACL-R patients. Development of new tests to determine the relevant role of the sensorimotor system is needed. These tests should ideally be used as screening tests for primary and secondary prevention of ACL injury.

Currently, no blood biomarker that specifically indicates injury to the proximal tubule of the kidney has been identified. Kidney injury molecule-1 (KIM-1) is highly upregulated in proximal tubular cells following kidney injury. The ectodomain of KIM-1 is shed into the lumen, and serves as a urinary biomarker of kidney injury. We report that shed KIM-1 also serves as a blood biomarker of kidney injury. Sensitive assays to measure plasma and serum KIM-1 in mice, rats, and humans were developed and validated in the current study. Plasma KIM-1 levels increased with increasing periods of ischemia (10, 20, or 30 minutes) in mice, as early as 3 hours after reperfusion; after unilateral ureteral obstruction (day 7) in mice; and after gentamicin treatment (50 or 200 mg/kg for 10 days) in rats. In humans, plasma KIM-1 levels were higher in patients with AKI than in healthy controls or post-cardiac surgery patients without AKI (area under the curve, 0.96). In patients undergoing cardiopulmonary bypass, plasma KIM-1 levels increased within 2 days after surgery only in patients who developed AKI (P<0.01). Blood KIM-1 levels were also elevated in patients with CKD of varous etiologies. In a cohort of patients with type 1 diabetes and proteinuria, serum KIM-1 level at baseline strongly predicted rate of eGFR loss and risk of ESRD during 5-15 years of follow-up, after adjustment for baseline urinary albumin-to-creatinine ratio, eGFR, and Hb1Ac. These results identify KIM-1 as a blood biomarker that specifically reflects acute and chronic kidney injury.

Occupational rhinitis in workers investigated for occupational asthma
Authors: R Castano, D Gautrin, G Theriault, C Trudeau, H Ghezzo, J-L Malo
Journal: Thorax (2008)

<h3>Background:</h3> The links between asthma and rhinitis are now referred to as united airways disease (UAD). Current evidence shows that the UAD model seems to be applicable to occupational rhinitis (OR) and occupational asthma (OA). A study was undertaken to objectively assess, in the context of specific inhalation challenge (SIC) testing, the concomitance of bronchial and nasal reaction in the investigation of OR and OA. <h3>Methods:</h3> 43 subjects with a history of work-related asthma symptoms underwent SIC for confirmation of OA and investigation of OR. Changes in bronchial calibre were measured by spirometry and nasal patency and airway inflammation were assessed by acoustic rhinometry and nasal lavage. <h3>Results:</h3> A positive nasal challenge was observed in 25 SIC tests and a positive bronchial challenge was observed in 17 SIC tests. A concomitant positive nasal and bronchial challenge was observed in 13 instances. This association was significant (risk ratio = 1.7; 95% CI 1.0 to 2.4; p = 0.04) and more frequent in subjects challenged with high molecular weight agents (n = 11/22) than with low molecular weight agents (n = 2/21). In subjects with a positive nasal challenge, nasal lavage showed a significant increase in eosinophils 30 min after exposure which correlated with changes in nasal patency. <h3>Conclusion:</h3> The results of this study provide objective evidence to support the concept of UAD using OR and OA as a model to demonstrate a significant concomitant physiological reaction of the nose and lungs after challenge. This study shows that OR can be assessed by objective means; it often coexists with OA but can be present without OA.

Symptoms and Well-Being in Relation to Glycemic Control in Type II Diabetes
Authors: Ferdinand E E Van der Does, J Nico D De Neeling, Frank J Snoek, Pieter J Kostense, Peter A Grootenhuis, Lex M Bouter, Robert J Heine
Journal: Diabetes Care (1996)

To describe the cross-sectional relation between glycemic control and physical symptoms, emotional well-being, and general well-being in patients with type II diabetes.The study population consisted of 188 patients with type II diabetes between 40 and 75 years of age. Patients were treated with blood glucose-lowering agents or had either a fasting venous plasma glucose level > or = 7.8 mmol/l or an HbA1c level > 6.1%. Multiple regression analyses were performed. Dependent variables were scores on the Type II Diabetes Symptom Checklist, the Profile of Mood States, the Affect Balance Scale, and questions regarding general well-being. The primary determinant under study was HbA1c. In addition, age, sex, neuroticism (indicating a general tendency to complain), insulin use, and comorbidity were included as determinants in all analyses. Other potential determinants taken into consideration were hypoglycemic complaints, marital status, diabetes duration, cardiovascular history, blood pressure, BMI, waist-to-hip ratio, perceived burden of treatment, and smoking. None of these potential determinants had to be included to correct confounding of the relation between HbA1c and well-being scores.Higher HbA1c levels were significantly associated with higher symptom scores (total score, hyperglycemic score, and neuropathic score), with worse mood (total score, displeasure score, depression, tension, fatigue), and with worse general well-being. The relative risks varied between 1.02 and 1.36 for each percentage difference in HbA1c. The relation between HbA1c and some mood states was modified by neuroticism: in the less neurotic patient (i.e., one who is less inclined to complain), the relation was more evident.These data suggest that better glycemic control in type II diabetes is associated with fewer physical symptoms, better mood, and better well-being, in a nonhypoglycemic HbA1c range.
Platelet activation attracts a subpopulation of effector monocytes to sites of <i>Leishmania major</i> infection
Authors: Ricardo Goncalves, Xia Zhang, Heather Cohen, Alain Debrabant, David M. Mosser
Journal: The Journal of Experimental Medicine (2011)

Leishmania species trigger a brisk inflammatory response and efficiently induce cell-mediated immunity. We examined the mechanisms whereby leukocytes were recruited into lesions after Leishmania major infection of mice. We found that a subpopulation of effector monocytes expressing the granulocyte marker GR1 (Ly6C) is rapidly recruited into lesions, and these monocytes efficiently kill L. major parasites. The recruitment of this subpopulation of monocytes depends on the chemokine receptor CCR2 and the activation of platelets. Activated platelets secrete platelet-derived growth factor, which induces the rapid release of CCL2 from leukocytes and mesenchymal cells. This work points to a new role for platelets in host defense involving the selective recruitment of a subpopulation of effector monocytes from the blood to efficiently kill this intracellular parasite.
Natural History and Preventative Treatment of Recurrent Mood Disorders
Authors: Ellen Frank, PhD, Michael E. Thase, MD
Journal: Annual Review of Medicine (1999)

This chapter focuses on recent developments in our understanding of the etiology, epidemiology, and treatment of recurrent mood disorders. It addresses the changing relationship between endogenous and exogenous factors over time in the etiology of mood episodes. In the area of epidemiology, the chapter presents new information on the prevalence of various subtypes and male/female differences in lifetime risk. Complications of the mood disorders, such as suicide, and important comorbidities, including alcoholism and substance abuse, are discussed. In the area of treatment, the life-long nature of many of the mood disorders is described, as is the consequent role of the primary care physician in their management. The evidence for the efficacy of the depression-specific psychotherapies, cognitive therapy and interpersonal therapy, is reviewed. Current issues in the pharmacotherapy of mood disorders are discussed, including the relative efficacy of the older antidepressants versus the newer selective serotonin reuptake inhibitors (SSRIs) and the treatment of various subtypes of mood disorders, including dysthymia, chronic depression, and atypical depression. Finally, the chapter describes recent advances in the treatment of bipolar disorder.
Decreased effect of insulin to stimulate skeletal muscle blood flow in obese man. A novel mechanism for insulin resistance.
Authors: M Laakso, S V Edelman, G Brechtel, A D Baron
Journal: Journal of Clinical Investigation (1990)

Obesity is characterized by decreased rates of skeletal muscle insulin-mediated glucose uptake (IMGU). Since IMGU equals the product of the arteriovenous glucose difference (AVGd) across muscle and blood flow into muscle, reduced blood flow and/or tissue activity (AVGd) can lead to decreased IMGU. To examine this issue, we studied six lean (weight 68 +/- 3 kg, mean +/- SEM) and six obese (94 +/- 3 kg) men. The insulin dose-response curves for whole body and leg IMGU were constructed using the euglycemic clamp and leg balance techniques over a large range of serum insulin concentrations. In lean and obese subjects, whole body IMGU, AVGd, blood flow, and leg IMGU increased in a dose dependent fashion and maximal rates of all parameters were reduced in obese subjects compared to lean subjects. The dose-response curves for whole body IMGU, leg IMGU, and AVGd were right-shifted in obese subjects with an ED50 two- to threefold higher than that of lean subjects for each parameter. Leg blood flow increased approximately twofold from basal 2.7 +/- 0.2 to 4.4 +/- 0.2 dl/min in lean, P less than 0.01, and from 2.5 +/- 0.3 to 4.4 +/- 0.4 dl/min in obese subjects, P less than 0.01. The ED50 for insulin's effect to increase leg blood flow was about fourfold higher for obese (957 pmol/liter) than lean subjects (266 pmol/liter), P less than 0.01. Therefore, decreased insulin sensitivity in human obesity is not only due to lower glucose extraction in insulin-sensitive tissues but also to lower blood flow to these tissues. Thus, in vivo insulin resistance can be due to a defect in insulin action at the tissue level and/or a defect in insulin's hemodynamic action to increase blood flow to insulin sensitive tissues.
Serum enzyme changes after major lung surgery--with and without halothane
Authors: A. R. Hunter
Journal: Thorax (1968)

The postoperative changes in serum aspartate aminotransferase (SGOT), serum alanine aminotransferase (SGPT), and lactate dehydrogenase (LDH) levels after major lung operations were studied in patients some of whom received halothane and some of whom did not. There were no differences between the two groups of cases. It seemed possible that the rises in SGOT and LDH which occurred quite frequently were an indication that tissue autolysis was occurring in the body.
Mucin secretion in inflammatory bowel disease: correlation with disease activity and dysplasia.
Authors: M Ehsanullah, M I Filipe, B Gazzard
Journal: Gut (1982)

When rectal biopsies from 65 patients with ulcerative colitis and 20 patients with Crohn9s disease was stained for mucins, an abnormal pattern (excess of sialomucins) was seen in about half of them. This is in contrast with 65 cases of non-specific proctitis where the mucin pattern of rectal biopsies was normal in all except one case. The abnormal mucin secretion in patients with ulcerative colitis was apparently related to the activity, duration, and extent of the disease. All biopsies with dysplasia showed predominant sialomucin staining except one. All biopsies showing sialomucins during remission also had dysplasia, while during active disease a number of biopsies had increased sialomucins without the evidence of dysplasia. It is not known if such cases will subsequently develop morphological atypia.

Airway remodelling inducing structural and functional decline is a main factor leading to clinical disablement in chronic obstructive pulmonary disease (COPD) [1]. However, whether airway remodelling is also a potential feature of the normal healing process in ordinary lifelong environmental exposure and chronic endogen damage due to senescence is not well elucidated [2]. The relationship between ageing and development of COPD is complex. On one hand, while there is a higher prevalence of COPD in the elderly, ageing is not the direct cause of COPD; on the other hand, it does increase the susceptibility of the lung to extrinsic damage [3]. Airway remodelling with age is a heterogeneous process having a particular tropism towards distal airways <http://ow.ly/FeZnN> We thank all the volunteers who participated in this research study; Melina Bouet, Claire Belloc and Erika Nogue for logistical assistance and data management; and Pamela Goodman-Stephens for her linguistic contribution (all CHU Montpellier, Montpellier, France).
