Korištenje otpadnog mulja i diatomita kao medija u proizvodnji sadnica običnog bora (Pinus sylvestris L.) i procjena preživljavanja sadnica na terenu

Although several organic and inorganic substrates are added to growing media for improving its physical and chemical characteristics, the need for search of new materials and/or mixtures that reduces the high-priced peat content in substrates is still interesting. This study evaluated the feasibility of reducing the peat content in substrates by replacing it with different amounts of diatomite and sewage sludge for Scots pine seedling (Pinus sylvestris L.) growth and their land performance. In order to evaluate the feasibility of reducing the peat content in substrates by replacing it with different amounts of diatomite and sewage sludge, an experiment was carried out in a temperature-controlled greenhouse under natural light. To evaluate the land performance of Scots pine seedlings grown in different substrates, a trial was established between the years 2013-2017 in Sarıkamış, Kars (NE Anatolia). Sewage sludge application, due to its high organic matter and macro and micronutrient content, has improved the composition of the rhizosphere, thereby resulting in growth acceleration. As a result of the evaluations made in terms of both seedling morphological characteristics and land performance; the best performance was determined in the 9th (50%P+50%SS) and 3rd (75%SS+25%DE) mixtures.Unatoč tome što se supstratu za uzgoj dodaju određeni organski i anorganski supstrati kako bi se poboljšale njegove fizičke i kemijske karakteristike, i dalje je zanimljiva potreba za istraživanjem novih materijala i/ili smjesa koje smanjuju udio skupocjenog treseta u supstratima. U ovom radu procijenit će se izvedivost smanjenja sadržaja treseta u supstratima njegovom zamjenom s različitim količinama diatometa i mulja iz otpadnih voda za rast sadnica običnog bora (Pinus sylvestris L.) te njihovo preživljavanje na terenu. Kako bi se procijenila izvedivost smanjenja sadržaja treseta u supstratima zamjenom s različitim količinama diatometa i mulja iz otpadnih voda, provedeno je istraživanje u stakleniku, pod prirodnim svjetlom i u kontroliranim temperaturnim uvjetima. Između 2013. i 2017. godine u mjestu Sarıkamış, Kars (SI Anadolija) pokrenuto je istraživanje kojim će se procijeniti učinak koje zemljište ima na sadnice običnog bora koje rastu u različitim supstratima. Visoko organske tvari te makro i mikrohranjivi sastojci koji se nalaze u mulju iz otpadnih voda poboljšali su sastav rizosfere. što je rezultiralo bržim rastom sadnica. Kao rezultat evaluacija obavljenih u pogledu morfoloških karakteristika sadnica i utjecaja koji zemljište ima na preživljavanje sadnica; najbolji učinak postignut je u 9. (50%P + 50%SS) i 3. smjesi (75%SS + 25%DE)

Autoantibody frequency in celiac disease

AIM: In our study, we investigated the levels of glutamic acid decarboxylase antibody (anti-GAD), islet cell antibody (ICA), thyroperoxidase antibody (anti-TPO), thyroglobulin antibody (anti-TG), antinuclear antibodies (FANA), antibodies to double-stranded DNA (anti-ds DNA), antibody to Sjögren syndrome A antigen (anti-SSA), antibody to Sjögren syndrome B antigen (anti-SSB), Smith antibody (anti-Sm), smooth muscle antibodies (ASMA), and antimitochondrial antibody liver-kidney microsome (AMA-LKM) in patients with celiac disease as compared to healthy controls and autoimmune hypothyroid patients. MATERIALS AND METHODS: A total of 31 patients with celiac disease, 34 patients with autoimmune hypothyroidism and 29 healthy subjects were included in this study. Anti-SSA, anti-SSB, anti-Sm, anti-ds DNA, anti-GAD, anti-TPO and anti-TG were studied by Enzyme-Linked Immunosorbent Assay (ELISA), and AMA-LKM, ASMA, ANA and ICA were studied by immunofluorescence. Clinical data and the results of free thyroxine-thyroid stimulating hormone (FT4-TSH) were collected from the patients’ files by retrospective analysis. SPSS ver 13.0 was used for data analysis, and the χ(2) method was used for comparisons within groups. RESULTS: The frequency of anti-SSA, anti-SSB, anti-GAD, anti-Sm, anti-ds DNA, AMA-LKM, ASMA, ANA and ICA were not significantly different between the groups. Levels of anti-TPO and anti-TG antibodies were found to be significantly higher (<0.001) in autoimmune hypothyroid patients when compared with other groups. CONCLUSION: In previous studies, an increased frequency of autoimmune diseases of other systems has been reported in patients with celiac disease. We found that the frequency of autoimmune antibodies specific for other autoimmune diseases was not higher in celiac disease

Screening for Cushing’s Syndrome in Obese Patients

OBJECTIVES: The aim of this study was to examine the frequency of Cushing's syndrome (CS) in obese patients devoid of specific clinical symptoms of Cushing's syndrome. METHODS: A total of 150 obese patients (129 female, 21 male; mean age 44.41 ± 13.34 yr; mean BMI 35.76 ± 7.13) were included in the study. As a first screening step, we measured 24-h urinary free cortisol (UFC). An overnight 1-mg dexamethasone suppression test was also performed on all patients. Urinary free cortisol levels above 100 &#956;g/24 h were considered to be abnormal. Suppression of serum cortisol <1.8 &#956;g/dL after administration of 1 mg dexamethasone was the cut-off point for normal suppression. The suppression of the serum cortisol levels failed in all of the patients. RESULTS: Measured laboratory values were as follows: ACTH, median level 28 pg/ml, interquartile range (IQR) 14-59 pg/ml; fasting glucose, 100 (91-113) mg/dL; insulin, 15.7 (7.57-24.45) mU/ml; fT4, 1.17 (1.05-1.4) ng/dL; TSH, 1.70 (0.91-2.90) mIU/L; total cholesterol, 209 (170.5-250) mg/dL; LDL-c, 136 (97.7-163) mg/dL; HDL-c, 44 (37.25-50.75) mg/dL; VLDL-c, 24 (17-36) mg/dL; triglycerides, 120.5 (86-165) mg/dL. The median UFC level of the patients was 30 &#956;g/24 h (IQR 16-103). High levels of UFC (>100 &#956;g/24 h) were recorded in 37 patients (24%). Cushing's syndrome was diagnosed in 14 of the 150 patients (9.33%). Etiologic reasons for Cushing's syndrome were pituitary microadenoma (9 patients), adrenocortical adenoma (3 patients), and adrenocortical carcinoma (1 patient). CONCLUSION: A significant proportion (9.33%) of patients with simple obesity were found to have Cushing's syndrome. These findings argue that obese patients should be routinely screened for Cushing's syndrome

The Relationships of Leptin, Adiponectin Levels and Paraoxonase Activity with Metabolic and Cardiovascular Risk Factors in Females Treated with Psychiatric Drugs

OBJECTIVES: The aim of this study was to investigate serum leptin, adiponectin and paraoxonase1 levels in adult females receiving pharmacotherapy for various psychiatric disorders. METHODS: The study group consisted of 32 obese females (mean age 40.53 ± 11.00 years, mean body mass index 35.44 ± 5.33 kg/m²) who were receiving treatment for psychiatric disorders, and the control group included 22 obese females (mean age 35.95 ± 9.16 years, mean body mass index 30.78 ± 3.33 kg/m²) who were free of psychiatric disorders. Analyses were performed using a bioelectrical impedance device. Fasting blood samples were obtained for complete blood count and various biochemical tests, including determination of leptin, adiponectin and paraoxonase1 activity. RESULTS: Body mass index, waist and hip circumference, body fat percentage, fasting blood glucose, insulin, glycosylated hemoglobin, homeostasis model assesment of insulin resistance, alanine transaminase, aspartate tarnsaminase, and leptin levels were significantly higher in the study group than in controls. Although body weight was positively correlated with leptin levels in both groups, body weight was negatively correlated with adiponectin levels in the control group and positively correlated with adiponectin levels in the study group. In the study group, body mass index and hip circumference correlated positively with leptin levels, hip circumference correlated positively with adiponectin levels, and waist to hip ratio correlated positively with paraoxonase levels. In the control group, body mass index as well as waist and hip circumferences were positively correlated with leptin levels. Weight, body mass index, and hip circumference were also negatively correlated with the adiponectin/leptin ratio in the control group. CONCLUSION: This study indicates a higher risk for obesity-related disorders, particularly metabolic syndrome, diabetes and cardiovascular disease, in patients treated with psychiatric drugs

Peptic ulcer disease in endogenous hypercortisolism: myth or reality?

Many clinicians believe hypercortisolism is ulcerogenic. However, data from clinical studies show that prophylaxis for peptic ulcer disease is no longer recommended in patients receiving corticosteroid treatment. This has not yet been verified in endogenous hypercortisolism by controlled clinical studies. The purpose of the current study was to evaluate the relationship between endogenous Cushing's syndrome (CS) and peptic ulcer disease and Helicobacter pylori infection. The study group contained 20 cases with CS resulting from ACTH-dependent endogenous hypercortisolism. The control groups consisted of 14 age- and gender-matched cases receiving exogenous corticosteroid therapy and 100 cases of dyspepsia with non-cushingoid features. Upper gastrointestinal endoscopy was performed on all cases. Biopsies were taken from five different points: two samples from the antrum, two samples from the corpus, and one sample from the fundus. A histological diagnosis of Helicobacter pylori infection was also obtained from evaluation of biopsy specimens. The frequency of stomach and duodenal ulcers did not vary between the groups (p = 0.5 and p = 0.7). Antral gastritis was less frequent and pangastritis was more common in cases with CS compared to the healthy controls (p = 0.001 and p < 0.001). The incidence of Candida esophagitis was more frequent in cases with CS compared to cases with corticosteroid treatment and healthy controls (p = 0.03). Histopathological findings and frequency of Helicobacter pylori based on pathology results did not vary between the three groups. It is possible that neither exogenous nor endogenous corticosteroid excess directly causes peptic ulcer or Helicobacter pylori infection. Prophylactic use of proton pump inhibitors is not compulsory for hypercortisolism of any type

Anti-scl-70 antibodies in autoimmune hypothyroidism

The relationship between autoimmune thyroiditis and systemic sclerosis is controversial. Data exist on the presence of thyroid autoantibodies in patients with systemic sclerosis but, as far as we could ascertain, anti-Scl-70 antibodies, which are highly specific for systemic sclerosis, have not been investigated in autoimmune hypothyroidism. This study compares the presence of anti-Scl-70 in females with autoimmune hypothyroidism (n = 24) and in healthy age-matched female controls (n = 26). Free thyroxine levels were similar in both groups. Thyroid stimulating hormone (TSH), antithyroid peroxidase (anti-TPO), antithyroglobulin (anti-Tg) and index values for anti-Scl-70 levels were significantly higher in patients with autoimmune hypothyroidism compared with controls, although the anti-Scl-70 test was negative in both groups. Anti-TPO, anti-Tg and TSH significantly correlated with anti-Scl-70. In conclusion, autoimmune hypothyroidism seems to be associated with a higher index level of anti-Scl-70, yet a negative anti-Scl-70 antibody test. This suggests that autoimmune hypothyroidism might have common aetiological factors with systemic sclerosis
