Objective(s): To elucidate the effects and potential mechanisms of hypericin-photodynamic therapy (HYP-PDT) for treating the human rheumatoid arthritis (RA) fibroblast-like synoviocyte (FLS) MH7A cell-line. Materials and Methods: MH7A cells were subjected to HYP-PDT intervention and apoptosis was evaluated via MTT, nuclear staining, and flowcytometry analyses. Intracellular reactive oxygen spec...

using hartree-fock su-sheriffer-heeger (hf-ssh) model, we have studied the dependence of the energies of the ground (magnetic triplet state) and the first exited (nonmagnetic singlet state) states of the size-2 trigonal zigzag graphene nanoflake (size-2 nf) on the intensity of an external in plane static electric field at zero temperature. we identify a transition from the magnetic triplet stat...

background: bone marrow stromal cells (bmsc) are used as a source for cell therapy in different model for neurological disorder such as stroke and spinal cord injury. however, the transdifferentiation of bmsc into cholinergic phenotype requires more investigation. methods: bmsc were isolated from adult rats, pre-induced with β-mercaptoethanol (bme) and followed by nerve growth factor (ngf) indu...

The presence of lignin and its degraded products such as tannin and humic acids is the main reason causing the aerobically-treated palm oil mill effluent (AT-POME) to display colour at the point of discharge. In this work, a hybrid method is developed to treat the AT-POME sample that was conventionally treated by biological method. This hybrid method combines coagulation and nanofiltration (NF)...

background :adenosine is an endogenous purine nucleoside that has a neuromodulatory role in the central nervous system. the amphetamine derivative (±)-3,4-methylenedioxymethamphetamine (mdma or ecstasy) is a synthetic amphetamine analogue used recreationally to obtain an enhanced affiliated emotional response. mdma is a potent monoaminergic neurotoxin with the potential of damage to brain neuro...
