Serum homocysteine, folic acid, lipoprotein (a) (Lp(a)), fibrinogen, and C-reactive protein (CRP) concentrations and erythrocyte sedimentation rates (ESR) were measured in 52 patients with familial Mediterranean fever (FMF) during attack-free periods and in 30 healthy control subjects. Serum homocysteine levels were significantly higher in the FMF patients (median 17.8 microg/dl; range 5.6-80.8...

The anionic ring-opening polymerizations (AROP) of bio-based N-acetyl homocysteine thiolactone (NHTL) and different epoxides were carried out using benzyl alcohol 2-tert-butylimino-2-diethylamino-1,3-dimethylperhydro-1,3,2-diazaphosphorine (BEMP) as initiating system. This polymerization is a rare example AROP in the presence an acidic moiety (acetamido group). Well-defined alternating poly(est...

Homocysteinylation of lysine residues by homocysteine thiolactone (HCTL), a reactive homocysteine metabolite, results in protein aggregation and malfunction, and is a well-known risk factor for cardiovascular, autoimmune and neurological diseases. Human plasma paraoxonase-1 (PON1) and bleomycin hydrolase (Blmh) have been reported as the physiological HCTL detoxifying enzymes. However, the catal...

Various post-translational lens crystallins modifications result in structural and functional insults, contributing to the development of lens opacity and cataract disorders. Lens crystallins are potential targets of homocysteinylation, particularly under hyperhomocysteinemia which has been indicated in various eye diseases. Since both homocysteinylation and acetylation primarily occur on prote...

Purpose: Hyperhomocysteinemia in children can develop as a result of genetic defects, endocrine abnormalities or under the influence dietary factors. An elevated level homocysteine is considered risk factor for progression chronic kidney disease. The aim work was to investigate indicators oxidative stress homogenate kidneys immature rats control and with hyperhomocysteinemia. Methods: concentra...

We have shown that Caenorhabditis elegans lacking the PCM-1 protein repair l-isoaspartyl methyltransferase are more sensitive to oxidative stress than wild-type nematodes. Exposure to the redox-cycling quinone juglone upon exit from dauer diapause results in defective egg-laying (Egl phenotype) in the pcm-1 mutants only. Treatment with paraquat, a redox-cycling dipyridyl, causes a more severe d...

Aim: In this study, we evaluated the clinical and laboratory data of healthy children with vitamin B12 deficiency. The benefits methylmalonic acid (MMA) homocysteine levels difficulties encountered in diagnosing deficiency were pointed out. 
 Materials Methods: A total 70 whose serum cobalamin below 126.5 pg/ml included study. age, gender, B12, urine MMA, plasma homocysteine, white blood c...
