Image at Surface

When we see an image, by here I mean a visual image such as a photograph, film or video, we perceive it at its surface, just like when we approach a physical object, we experience the physical surface of it. My project and research focus on digital image, which manifests the virtual materiality at the image surface. When we describe materiality at the physical surface, we usually describe a sensory experience of looking, touching, tasting, etc. Similarly, the materiality of an image is associated with bodily experiences—while our minds comprehend and dissect the image, our body are simultaneously sensing its surface. The image’s materiality, influenced by the recorded material, space, time, rhythm, motion, and story, corresponds to the physical space, real time, physical motion, as well as our body. Eventually the recorded materials in the filmic scenes appear as the imagery materiality at the image surface. Our experience of the image surface is then connected with our perception of the physical surface, and our attachment to the physical material shifts to an attachment to the virtual body

Effect of glaucocalyxin B on the protein expressions of PTEN, Beclin1 and LC3 in a mouse model of transplanted cervical cancer, and its significance

Purpose: To determine the effect of glaucocalyxin B (GLB) on the protein expressions of PTEN, Beclin1 and LC3 in a mouse model of transplanted cervical cancer, and its significance.Methods: A mouse model of transplanted cervical cancer was established in female BALB/C mice. The model mice were divided into control group, low-dose GLB group and high-dose GLB group. Mice in low-dose and high-dose groups were given intraperitoneal injection of low-dose GLB and high-dose GLB, respectively. The volume and weight of transplanted tumor were measured and compared between the two groups. Serum levels of CEA and CA125 were assayed by enzyme-linked immunosorbent assay (ELISA). The expressions of phosphatase and tensin homolog (PTEN), autophagy-related factor microtubule-associated protein-1 (Beclin-1), microtubule-associated protein 1 light chain 3 (LC3), apoptosis-related protein p53, and Bax were determined using SABC immunohistochemical operation.Results: On days 5, 10 and 15, the volume and weight of transplanted tumor, and levels of CA125 and CEA in low- and high-dose GLB groups were significantly and dose-dependently lower than those in control group (p < 0.05). Results from immunohistochemistry showed that the protein expression levels of PTEN, Beclin-1, LC3, p53 and Bax were significantly and dose-dependently higher in low- and highdose GLB groups than in the control group (p < 0.05).Conclusion: Glaucocalyxin B significantly and dose-dependently induces apoptosis of cervical cancer cells and inhibits their growth by regulating the protein expressions of PTEN, Beclin1 and LC3. Thus, glaucocalyxin B is a potential adjunct therapy in the management of cervical cancer

Effects of 4 weeks of whole-body vibration training on energy expenditure during deep squats of male well-trained students

From the perspective of energy expenditure, this study investigated the effects of whole-body vibration training on the energy metabolism of deep squats with different weights. Twenty-two healthy male college students with sports experiences were selected and randomly assigned to perform resistance exercise vibration (REV) or resistance exercise (RE) with varying loads two times per week for 4 weeks. Oxygen uptake and heart rate were measured before, during, and after exercises using a gas analyzer, and energy expenditure was calculated. The results showed the following: 1) the oxygen uptake and energy expenditure of the REV group were significantly higher than those of the RE group during and 30 min after exercise (p < 0.01), respectively, and the excess post-exercise oxygen consumption (EPOC) was also significantly higher than that of the RE group (p < 0.01). 2) Changes in the oxygen uptake and energy expenditure were stable with increasing exercise in both vibration and non-vibration conditions. There was no difference in energy expenditure per unit of body mass versus additional energy per kilogram of body weight (p > 0.05). 3) No significant differences in changing exercise intensity were observed in the REV group compared to those in the RE group during the adjacent incremental load phases of △ (40%–0%) and △ (80%–40%) of load during and 30 min after exercise (p > 0.05). Our results suggest that 1) vibration training can increase energy expenditure during low-intensity training and excess post-exercise oxygen consumption, and improve the exercise intensity. 2) The effects on energy expenditure were the same for both weight-bearing and non-weight-bearing deep squats, up to 40% of body mass
