A new biocatalytic assay analyzing the simultaneous presence of creatine kinase (CK) and lactate dehydrogenase (LDH) was developed aiming at the recognition of biofluids of different ethnic origins for forensic applications. Knowing the difference in the concentrations of CK and LDH in the blood of healthy adults of two ethnical groups, Caucasian (CA) and African American (AA), and taking into ...

AIM To assess the inhibitory effect of agmatine on tumor growth in vivo and tumor cell proliferation in vitro. METHODS The transplanted animal model, [3H]thymidine incorporation assay,3-[4,5-dimethythiazol-2-yl]-2,5-diphenyltetrazolium assay, and lactate dehydrogenase (LDH) release assay were performed. RESULTS Agmatine, at doses of 5-40 mg/kg, suppressed the S180 sarcoma tumor growth dose-...

Bisphenol F (BPF) has been used frequently in the plastics industry and production of daily consumer products as an alternative to bisphenol A (BPA). It was aimed herein determine cytotoxic effects BPF on hepatocytes isolated from liver rainbow trout (Oncorhyncus mykiss) using lactate dehydrogenase (LDH) assay antioxidant defence system indicators. The cultured were exposed seven concentrations...

Hydrophilins are a wide group of proteins whose defining characteristics are high hydrophilicity index (> 1.0) and high glycine content (> 6%). The transcripts of most hydrophilins accumulate in response to water deficit in organisms such as plants, fungi and bacteria. In plants, most of the known Late Embryogenesis Abundant (LEA) proteins belong to this group (Garay-Arroyo et al., Journal of B...

The present study is to investigate the effect of the active fraction of Flos Daturae (AF-FD) (dried flower of Datura metel L.) on IFNinduced apoptosis in a human keratinocyte cell line (HaCAT), which is a widely accepted mimic model of psoriasis. Accordingly, we used MTT and LDH to assay cell viability, FCM and Hoechst 33342 staining to assay cell apoptosis, and Western blotting to assay the e...

Maintaining protein conformational stability and integrity during formulation is critical for developing protein pharmaceuticals. Accordingly, high sensitivity differential scanning calorimetry (HSDSC) and Fourier transform (FT)-Raman spectroscopy were employed to assess conformational stabilities (thermal stability and folding reversibility) and structural integrities, respectively, for three ...

objective: envenomation by heamotoxic snakes constituted a critical health occurrence in the world. bleeding is the most sever consequence following snake bite with viperid and crothalid snakes. it is believed that the degradation of vascular membrane caused hemorrhage; in contrast, some suggested that direct cytotoxicity has role in endothelial cell disturbances. this study was to evaluate the...

Lumbar disc herniation (LDH) is a term used for a group of conditions, including back pain, femoral nerve pain and sciatica. Currently available treatments and surgical options are insufficient for patients with LDH. Fructus Ligustri Lucidi (FLL) is a herb that is used for treating age-associated diseases. The results of the present study suggested that FLL may be used for treatment of patients...

The immunological properties of a panel of synthetic peptides that represent the most accessible and mobile segments of the lactate dehydrogenase (LDH)-C4 molecule were characterized. Peptides corresponding to mouse LDH-C4 amino acid sequences: 1-14b, 5-15, 49-58, 97-110, 211-220, 231-243, 274-286, 304-316, and 318-330 were synthesized and compared in terms of binding antibodies raised in rabbi...
