Hla-G ve kanser İlişkisi

The importance of HLA antigens on immunity and tissue compatibility is known. The suppressor role of a non classical HLA antigen HLA-G is being clearer with the results of last studies. On normal situations its being is restricted in a few type of tissue. It can be found on fetal tissues like trophoblasts, tymic medulla, cornea, pancreatic islets and precursors of erithroid and endothelial cells. The expression of HLA-g is increased in the situations like malignities, transplantation, multiple sclerosis, inflammatory diseases and viral infections. In this review it is aimed to give short information on HLA system and to introduce the studies pronouncing the relation of HLA-G and malignities. © 2012 Düzce Medical Journal

Regeneration and Healing of Bone and Cartilage in Type-1 and Type-2 Diabetes: The Effects of Insulin

Increased fragility of long bones and delay in fracture healing in adults as well as skeletal development disorders in children are thought to be associated with endochondral ossification problems. The extracellular matrix (ECM) of cartilage is absorbed during endochondral ossification. During the recovery process from damage, chondrocytes undergo hypertrophy and increase their cell volume; on the other hand, it is also necessary to digest the ECM elements around the cells. Recent research on the proteolytic enzymes in ECM assumed to be responsible for the digestion is connected to proteinases digesting type II collagen and aggrecan. ADAMTS1, 4, and 5 are known as major aggrecanases within the matrix metalloproteinase (MMP) enzymes in human cartilage. These are regarded as main determiners among MMPs of bone growth, healing, and remodeling. In this mini review article, the remodeling and restoration of osseous tissue in type-1 and -2 diabetes mellitus (DM) and the effect of insulin on these processes are discussed briefly in the light of the current literature.WoSScopu

Relationship of maternal serum resistin and visfatin levels with gestational diabetes mellitus

WOS: 000334743400007PubMed: 24512558Introduction: Adiponectin, resistin and visfatin are thought to play role in the pathophysiology of gestational diabetes (GDM). In this study, we aimed to investigate the association of maternal second trimester serum resistin and visfatin levels with GDM. Materials and methods: Screening and diagnosis for GDM was performed between the 24-28th gestational weeks. About 40 women diagnosed with GDM and 40 non-diabetic women constituted the study and control groups, respectively. Groups were compared for second trimester maternal serum resistin, visfatin and HbA1c levels, HOMA-IR and postpartum 75 g OGTT results. Results: Mean serum resistin (p = 0.071) and visfatin (p = 0.194) levels were similar between the groups. However, mean BMI (p = 0.013), HOMA-IR (p = 0.019), HbA1c (p<0.0001) and birth weight (p = 0.037) were significantly higher in GDM group compared to controls. Type 2 diabetes and impaired glucose tolerance were detected in 2 (5%) and 7 (20%) women in the GDM group, respectively, with 75 g OGTT performed at the postpartum 6th week. Resistin levels of patients with GDM and postpartum glucose intolerance were higher than those with GDM but no postpartum glucose intolerance (p = 0.012). Visfatin levels in the GDM group showed a positive correlation with biparietal diameter, head circumference, abdominal circumference and femur length (p<0.05). Conclusion: Maternal serum resistin and visfatin levels are unchanged in GDM. In patients with GDM, second trimester resistin levels may be predictive for postpartum glucose intolerance and second trimester visfatin levels may be related with fetal biometric measurements. Further larger studies are needed.Duzce University, Medical Faculty Scientific Study Research CommissionDuzce University [2012.04.HD.060]The authors report no declarations of interest.

The Relation Between Hla-G And Cancer

HLA antijenlerinin doku uyumu ve immünite açısından önemi bilinmektedir. HLA sınıf 1 antijenlerinden non-klasik gruba dâhil olan HLA-Gnin kanser immunitesindeki baskılayıcı rolü son zamanlarda yapılan çalışmalarda daha da açığa çıkarılmıştır. HLA-G normal durumlarda çok kısıtlı dokularda bulunmaktadır. Trofoblastlar gibi fetal dokularda, timik medulla, kornea, pankreatik adacıklarda ve eritroid ve endotelial hücre prekürsörlerinde bulunmaktadır. HLA-G ekspresyonu bu fizyolojik durumların dışında kanserler, transplantasyon, multiple scleroz, inflamatuar hastalıklar ve viral enfeksiyonlar gibi patolojik durumlarda da artmış seviyelerdedir. Bu derlemede HLA sistemi hakkında kısaca bilgi verilerek HLA-G ile kanser ilişkisini vurgulayan farklı kanser türleri üzerinde yapılmış çalışmaları ortaya koymak amaçlanmıştır.The importance of HLA antigens on immunity and tissue compatibility is known.

Ankilozan spondilit hastalarında nötrofil- lenfosit oranı

Amaç: Bu çalışmanın amacı, ankilozan spondilit (AS) hastalarındaki inflamasyon ile nötrofil -lenfosit oranı (NLO) arasındaki ilişkiyi belirlemektir. Yöntem: Ankilozan spondilit tanılı 40 hasta ve 30 sağlıklı gönüllü çalışmaya dahil edildi. Tüm veriler yatan ve poliklinik hasta kayıt veritabanından elde edildi. Tüm olguların Bath Ankilozan Spondilit Hastalık Aktivite İndeksi (BA S- DAI), tam kan sayımı (TKS), CRP ve ESHı da kapsıyan ayrı ntılı fizik muayene ve laboratuvar bulguları kaydedildi. Lenfosit ve nötrofil sayısı otomatik TKSnin bir parçası olarak ölçüldü. Bulgular : Akut-faz reaktanı olan CRP ve ESH kontrol gr ubuna göre hasta grubunda anlamlı olarak daha yüksekti (p 0.05). Sonuç : Bu çalışmada NLO düzeylerinin AS hastalarında sağlıklı bireylere göre anlamlı olarak yüksek olmadığı görüldü. Bu sonuç NLOnun AS hastalarında sistemik in flamasyonu değerlendirmede uygun bir ölçü birimi olmad ığını götermektedir. Bizim elde ettiğimiz bu ön sonuçların daha ileri çalışmalarla tamamlanması gerektiğine inanıyoruz.Objective : The purpose of the present study is to determine the association between neutrophil -lymphocyte ratio (NLR) and inflammation in ankylosing spondylitis (AS). Method : Forty patients with ankylosing spondylitis and 30 healthy volunteers were included in the study. All data were obtained from patient registry database from in -patient and out-patient clinics. Detailed physical examination, and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) were record ed. Complete blood count (CBC), CRP and ESR were performed recorded as laboratory tests in all participants. Lymphocyte and neutrophil counts were measured as part of the automated CBC. Results : The CRP, which is an acute -phase reactant, and ESR were signi ficantly higher in the patient group than those in the control group (p0.05). Conclusion : We observed that NLR levels werent significantly higher in AS patients compared to healthy individuals. NLR hasnt seem a reasonable measure to detect systemic infla m- mation in AS patients. We believe that our preliminary results need to be complemented with further studies

Ceruloplasmin, copper, selenium, iron, zinc, and manganese levels in normal and sulfite oxidase deficient rat plasma: effects of sulfite exposure.

A noticeable effect of sulfite treatment was observed on the plasma ceruloplasmin ferroxidase activity of rats with normal sulfite oxidase activity when compared to normal controls. The plasma levels of selenium, iron, and zinc were unaffected by sulfite in normal and sulfite oxidase (SOX)-deficient rats. While plasma level of Mn was decreasing, plasma Cu level increased in SOX-deficient rats. Treating SOX-deficient groups with sulfite did not alter plasma level of Mn but made plasma level of Cu back to its normal level. This is the first evidence that Cu and Mn status were affected in experimental sulfite oxidase deficiency induced by low molybdenum diet with tungsten addition deserving further research to determine the underlying mechanisms of these observations in experimental sulfite oxidase deficiency

High sensitive CRP and sICAM-1 can predict Major Adverse Cardiovascular Events: MELEN Study: A Large Turkish Population Based Study

WOS: 000372103700004Objective: We aimed to evaluate the predictors of major adverse cardiovascular events (MACE) in a prospective population based study. Methods: This study included 153 participants aged>40 years with high and very high cardiovascular risk, and 50 participants aged>40 years with low cardiovascular risk according to the SCORE risk assessment. All the participants underwent a doppler ultrasound examination of carotid intima media thickness (CIMT), echocardiographic examination, ECG recording and various biochemical analyses. High-sensitivity C-reactive protein (hsCRP) was measured with chemiluminescent immunometric assay, serum amyloid-A (SAA) protein, soluble intercellular adhesion molecule-1 (sICAM), apolipoprotein-B (ApoB) were measured with ELISA method. eNOS single-nucleotide polymorphism was detected using polymerase chain reaction and restriction fragment length polymorphism methods. The follow-up was done 36 months after the baseline admission. MACE was defined as cardiovascular mortality or myocardial infarction or stroke. Results: Frequency of MACE was higher in high and very high risk group according to low risk group. There were no significant differences in eNOS gene polymorphisms between the risk groups and control subjects, and no significant association between eNOS gene polymorphisms and MACE was detected. Age, ejection fraction (EF), CIMT, hsCRP, ApoB, sICAM-1, and SAA protein levels were all significantly associated with MACE in univariate logistic regression analyses. Multivariate analyses revealed that age (OR: 1.08, CI: 1.02-1.15, p=0.013), EF (OR: 0.94, CI: 0.89-0.99, p=0.016), hsCRP (OR: 1.36, CI: 1.12-1.67, p=0.003) and sICAM-1 (OR: 81.0, CI: 1.04-6320, p=0.048) levels were the only independent predictors of MACE. Conclusion: Higher age, hsCRP and sICAM-1 levels and lower EF were independent predictors of MACE
