Cytotoxic effect of γ-sitosterol from Kejibeling (Strobilanthes crispus) and its mechanism of action towards c-myc gene expression and apoptotic pathway

Metode: Penelitian in vitro ini menggunakan kultur sel kanker kolon manusia (Caco-2), sel kanker hepar manusia (HepG2), sel kanker payudara tergantung hormon (MCF7) dan kultur sel normal hepar manusia (Chang Liver). Efek sitotoksik diukur melalui uji MTT melalui penentuan kadar yang membunuh 50% sel (IC50). Mekanisme sitotoksik dipelajari dengan menentukan pengaruh penambahan γ-sitosterol pada ...

Effect of age on ocular microtremor activity.

BACKGROUND Ocular microtremor (OMT) is a high-frequency tremor of the eyes. It is present in all individuals and is related to brainstem activity. The OMT signal appears as an irregular oscillatory movement with intermittent burst-like components. The clinical interest in OMT has centered on its use in the assessment of the comatose patient, with broad agreement among authors of its prognostic ...

Ocular microtremor measurement using laser-speckle metrology.

We describe a novel, noninvasive measurement approach for recording a small involuntary tremor of the eye known as ocular microtremor. The method is based on measuring out-of-plane angular displacements of a target by using laser-speckle correlation of images recorded in the Fourier plane of a lens. The system has a dynamic range of 4 to 5000 μrad, resolution of 4 μrad, and a bandwidth of 250 H...
