This study aims to investigate the interrelationship between German expressionist dance and grotesque art, with a specific focus on the analysis of Pina Bausch's renowned work, <Café Müller>. German expressionist dance emerged as a response to the social instability and economic downturn that followed World War I, leading to the introduction of expressionism and grotesque aesthetics. The incorporation of grotesque expression in dance plays a critical role in boldly portraying the destruction of the human condition and its underlying causes, thereby offering insights into social contradictions and the erosion of human nature. This research thoroughly explores the intricate connection between German expressionist dance and grotesque expression, providing a comprehensive analysis of Pina Bausch's <Café Müller> to reassess the profound meaning and significance of expressionist dance. Additionally, this study delves into the inherent grotesque tendencies embedded within the work, surpassing conventional notions of visual beauty and ugliness, and strives to reinterpret the essence of grotesque expression through the nuanced movements of the dancers and the integration of auditory elements within the performance.

Cisplatin is often effective in cancer treatment, but its clinical use is limited because of its nephrotoxicity. We have synthesized new platinum(II) coordination complexes (PC-1 & PC-2) containing trans-${\iota}$ and cis-1,2-diaminocyclohexane (DACH) as carrier ligands and L-3 -phenyllactic acid (PLA) as a leaving group with the aim of reducing nephrotoxicity but maintaining its anticancer activity. In this study, new platinum(II) complex compounds were evaluated for selective cytotoxicity on cancer cell-lines and normal kidney cells. The new platinum complexes have demonstrated high efficacy in the cytotoxicity against human bladder carcinoma cell-lines (T-24/HT-1376). The cytotoxicity of these compounds against rabbit proximal renal tubular cells and human renal cortical tissues, was determined by MTT assay, the [3H]-thymidine uptake and glucose consumption test, and found to be quite less than those of cisplatin. Based on our results, these novel platinum compounds appear to be valuable lead compounds with high efficacy and low nephrotoxicity.

Resveratrol (3,5,4'-trihydroxy-trans-stilbene) has been considered to be as one of major antioxidants present in grapes responsible for beneficial effects of red wine consumption on coronary heart disease. This triphenolic stilbene has been suggested as a potential cancer chemopreventive agent based on its striking inhiitory effects on diverse cellular events associated with tumor initiation, promotion, and progression. The compound has strong antioxidative and anti-inflammatory activities which amy contribute to its chemopreventive/chemoprotective properties. In the present work, we have found that resveratrol reduces viability and DNA synthesis capability of cultured human promyelocytic leukemia (HL-60) cells. Likewise, the viability of human breast cancer cell line, MCF-7 was reduced by resveratrol treatment. The growth inhibitory and antiproliferative properties of resveratrol appear to be associated with its induction of apoptotic cell death as determined by morphological and ultrastructural changes, agarose gel electrphoretic analysis of internucleosomal DNA fragmentation, and in situ terminal end-labeling of fragmented DNA (TUNEL). This compound also inhibited the phorbol ester-induced expression of cyclooxygenase-2 (COX-2) protein in immortalized human mammary epithelial MCF-10A cells. These results suggest that resveratrol has the promising cancer therapeutic/chemopreventive potential.

Propolis is a multicomponent, active, complex resinous substance collected by honeybees from a variety of plant sources. We have studied the effect of propolis on neurite outgrowth of SH-SY5Y human neuroblastoma cells induced to differentiate by all-trans-retinoic acid (RA). Propolis, at a concentration of $3{\mu}g/mL$, had no significant effect on the viability of differentiating SH-SY5Y cells. However, the neurite outgrowth of the differentiating SH-SY5Y cells treated with propolis ($0.3{\sim}3{\mu}g/mL$) for 48 hr was significantly inhibited in a dose-dependent manner. Treatment of RA-stimulated differentiating SH-SY5Y cells with 0.3 to $3{\mu}g/mL$ propolis resulted in decreased level of transglutaminase and 43-kDa growth-associated protein (GAP-43) in a dose-dependent manner. The results indicate that propolis is able to inhibit neurite outgrowth of differentiating SH-SY5Y cells.

Retinoids have many beneficial effects on dermatological applications. But, retinoids cause skin irritation. In this study, the safety of retinoids was clarified via both primary skin irritation test in rabbits and sensitization study using an integrated model for the differentiation of chemical-induced allergic and irritant skin reaction (IMDS), an alternative method to sensitization test. The effects of retinoids on the change of ultraviolet A (UVA)-induced matrix metalloproteinase-1 (MMP-1) in human skin fibroblasts and the modulation of type-1 pN collagen synthesis in hairless mice were examined to clarify the anti-wrinkle effects. Alltrans retinol (t-ROL) and its derivative, all-trans retinoic acid (t-RA), showed mild skin irritation but did not induce the sensitization. t-ROL and t-RA exerted anti-wrinkle effects by inhibiting the UVA-induced MMP-1 in human skin fibroblasts and increasing the type-1 pN collagen synthesis in hairless mice. These findings suggest that retinoids do not induce the allergy, and show anti-wrinkle effects by decreasing MMP-1 activation and increasing collagen synthesis.

Persistent cellular oxidative stress and enhanced lipid peroxidation (LPO) of PUFAs, leading to macromolecular damage and disruption of signaling pathways, are implicated in the development of human malignancies and other chronic degenerative diseases. LPO generates by oxidation of linoleic acid (LA) or arachidonic acid ($\omega$ -6 PUPAs) reactive aldehydes, such as trans-4-hydroxy-2-nonenal, which form etheno $\varepsilon$ -DNA adducts in a variety of human tissues and thus can contribute to diet-related cancers.(omitted)

We have previously shown that 2,4,3',5'-tetramethoxystilbene (TMS), a synthetic trans-stilbene analogue, is one of the most potently selective inhibitor of human cytochrome P450 1B1 in vitro and in vivo. In the present studies, the apoptotic effects of TMS were investigated in HL-60 cells. The effects of TMS on the proliferation of HL-60 cells were determined with MTT assay. TMS exhibited cytotoxicity with an $IC_50$ value of 37 nM. Cotreatment with TMS and etoposide, a well-known anticancer drug significantly enhanced the cytotoxicity. (omitted)
