Single-strand breaks were observed in rat lung and kidney after acute treatment of animals with CdCl2 (4 mg/kg body weight) injected intraperitoneally and NiCl2 (44.4 mg/kg body weight) injected subcutaneously. In the rat liver, no single-strand breakage was evident with those doses in single and combined metal treatments. The most susceptible tissue in rats to cadmium or nickel chloride treatment was the lung tissue. The single-strand breaks were higher in cadmium treatment than in nickel treatment in the rat lung. Also the response to cadmium treatment was obtained earlier than nickel. Rat kidney was also responsive to cadmium treatment. However, the response, although statistically significant, was much lower than the one obtained in rat lung. The combined treatment, which was done by administrating cadmium prior to nickel administration, reduced the number of single-strand breaks significantly and reversed them to control values in rat lung and kidney. This study confirms that cadmium and nickel create single-strand breaks when administered alone in the rat lung. This effect, which was seen in the single metal treatments, was reduced in the combined treatments. (C) 1997 Elsevier Science B.V.

SMN loss dysregulates microtubule-associated proteins in spinal muscular atrophy model Zobaroğlu Özer, Pelin; Koyunoğlu, Dila; Son, Çağdaş Devrim; Erdem-Yurter, Hayat Erdem; BORA, GAMZE (2022-05-01) © 2022 Elsevier Inc.Spinal muscular atrophy (SMA) is a rare neurodegenerative disease caused by the absence of survival motor neuron (SMN) protein. SMN loss results in impairments of the cytoskeleton, including microtubules and regulatory proteins. However, the contribution of microtubule-associated proteins (MAPs) to microtubule dysregulations in SMA is not fully understood. In this study, we investigated neuronal MAPs responsible for the microtubule stability and growth, including MAP1A, MAP2, MAP6, MAP7,...
Prospective evaluation of Vitamin K2, Raloxifene and their co-administration in osteoporotic rats Tasci, A. G.; BİLGİLİ, HASAN; Altunay, H.; Gecit, M. R.; Keskin, Dilek (Elsevier BV, 2011-07-17) In this study, therapeutic effects of Vitamin K2, Raloxifene and their co-administration on bone, uterus, blood and weight profiles were investigated with an ovariectomized rat model. Forty Wistar rats were divided into five groups (n = 8): Raloxifene (R), Vitamin K2 (K), Raloxifene + Vitamin K2 (R + K), ovariectomized controls (OVX) and Sham-operated controls (Sham). Treatment began 3 months after ovariectomy. Vitamin K2 and Raloxifene were administered 30 and 1.5 mg/kg/day separately and in combination fi...
STIMULATORY EFFECTS OF BENZENE ON RABBIT LIVER AND KIDNEY MICROSOMAL CYTOCHROME-P-450 DEPENDENT DRUG-METABOLIZING-ENZYMES ARINC, E; Adalı, Orhan; ISCAN, M; Güray, Nülüfer Tülün (Springer Science and Business Media LLC, 1991-01-01) Treatment of rabbits with benzene (880 mg/kg/day), s.c. for 3 consecutive days, caused 3.8- and 5.7-fold increases in aniline 4-hydroxylation rates of liver and kidney microsomes, respectively. Benzene treatment markedly enhanced hydroxylation rates of p-nitrophenol by liver and kidney by 7.2- and 4.2-fold, respectively. Both of these enzymes are associated with cytochrome P-450 LM3a. In contrast, the activity of benzphetamine N-demethylase, associated with P-450 LM2, was not altered significantly in eit...
Recent developments in cell-based assays and stem cell technologies for botulinum neurotoxin research and drug discovery. Kiriş, Erkan; Burnett, JC; Soloveva, V; Kane, CD; Bavari, S (2014-03-01) Botulinum neurotoxins (BoNTs) are exceptionally potent inhibitors of neurotransmission, causing muscle paralysis and respiratory failure associated with the disease botulism. Currently, no drugs are available to counter intracellular BoNT poisoning. To develop effective medical treatments, cell-based assays provide a valuable system to identify novel inhibitors in a time- and costefficient manner. Consequently, cell-based systems including immortalized cells, primary neurons, and stem-cell derived neurons h...
Reproductive toxicity parameters and biological monitoring in occupationally and environmentally boron-exposed persons in BandA +/- rma, Turkey DUYDU, YALÇIN; Basaran, Nursen; ÜSTÜNDAĞ, AYLİN; AYDIN DİLSİZ, SEVTAP; ÜNDEĞER BUCURGAT, ÜLKÜ; Ataman, Osman Yavuz; AYDOS, KAAN; Duker, Yalcin; Ickstadt, Katja; Waltrup, Britta Schulze; Golka, Klaus; Bolt, Hermann M. (2011-06-01) Boric acid and sodium borates have been considered as being "toxic to reproduction and development", following results of animal studies with high doses. Experimentally, a NOAEL (no observed adverse effect level) of 17.5 mg B/kg-bw/day has been identified for the (male) reproductive effects of boron in a multigeneration study of rats, and a NOAEL for the developmental effects in rats was identified at 9.6 mg B/kg-bw/day. These values are being taken as the basis of current EU safety assessments. The present...
