Mech. stimulations can prevent bone loss, but their effects on the tumor-invaded bone or solid tumors are elusive. Here, we evaluated the effect of knee loading, dynamic loads applied to the knee, on metastasized bone and mammary tumors. In a mouse model, tumor cells were inoculated to the mammary fat pad or the proximal tibia. Daily knee loading was then applied and metabolic changes were monitored mainly through urine. Urine samples were also collected from human subjects before and after step aerobics. The result showed that knee loading inhibited tumor progression in the loaded tibia. Notably, it also reduced remotely the growth of mammary tumors. In the urine, an altered level of cholesterol was observed with an increase in calcitriol, which is synthesized from a cholesterol derivative In urinary proteins, knee loading in mice and step aerobics in humans markedly reduced WNT1-inducible signaling pathway protein 1, WISP1, which leads to poor survival among patients with breast cancer. In the ex vivo breast cancer tissue assay, WISP1 promoted the growth of cancer fragments and upregulated tumor-promoting genes, such as Runx2, MMP9, and Snail. Collectively, the present preclin. and human study demonstrated that mech. stimulations, such as knee loading and step aerobics, altered urinary metabolism and downregulated WISP1. The study supports the benefit of mech. stimulations for locally and remotely suppressing tumor progression. It also indicated the role of WISP1 downregulation as a potential mechanism of loading-driven tumor suppression.

Lv, Chunrong; Larbi, Allai; Wu, Guoquan; Hong, Qionghua; Quan, Guobo published the artcile< Improving the quality of cryopreserved goat semen with a commercial bull extender supplemented with resveratrol>, Safety of (E)-5-(4-Hydroxystyryl)benzene-1,3-diol, the main research area is resveratrol semen extender cryopreservation goat; Antioxidant; Cryopreservation; Goats; Resveratrol; Semen.

The purpose of the current study was to evaluate the effects of resveratrol (RSV) on the quality of frozen-thawed goat sperm. Semen samples from four bucks were divided into five aliquots and diluted with a com. bull semen extender containing: no antioxidant (RSV-0, control), 10μM RSV (RSV-10), 50μM RSV (RSV-50), 100μM RSV (RSV-100) and 250μM RSV (RSV-250). After thawing, sperm motility, abnormal morphol., membrane and acrosome integrity, mitochondrial activity, phosphatidylserine (PS) distribution, and oxidative stress were evaluated. The results indicated that in comparison with the control, when the concentration of RSV was 10 or 50μM, the total motility, progressive motility, membrane and acrosome integrity, and mitochondrial activity of post-thaw spermatozoa was greater (P < 0.05). Addnl., the use of extenders containing RSV-10 or RSV-50 resulted in a greater percentage of viable spermatozoa as compared to the other groups (P < 0.05). Importantly, there were more viable spermatozoa (49.61 ± 0.61%) and less non-viable spermatozoa (49.16 ± 1.01%) in the RSV-50 group compared to the other extenders (P < 0.05). Furthermore, the use of the extenders containing RSV-10 and -50 resulted in a reduction in ROS production in frozen-thawed spermatozoa as compared to the control (P < 0.05). There, however, was no difference among extenders for abnormal morphol. and PS distribution. In conclusion, supplementation with RSV, at a concentration of 10 or 50μM in the semen extender, can improve the post-thaw goat sperm quality, which may occur as a consequence of inhibition of ROS generation.

Nguyen, Thao T.; Nguyen, Khang X.; Pham, Phuc H.; Ly, Duc; Nguyen, Duyen K.; Nguyen, Khoa D.; Nguyen, Tung T.; Phan, Nam T. S. published the artcile< Copper-catalyzed synthesis of pyrido-fused quinazolinones from 2-aminoarylmethanols and isoquinolines or tetrahydroisoquinolines>, Computed Properties of 5344-90-1, the main research area is aminoarylmethanol isoquinoline copper catalyst amination annulation cascade reacation; isoquinolino quinazolinone preparation; tetrahydroisoquinoline aminoarylmethanol copper catalyst amination annulation cascade reacation; dihydroisoquinolino quinazolinone preparation.

Pyrido-fused quinazolinones were synthesized via copper-catalyzed cascade C(sp2)-H amination and annulation of 2-aminoarylmethanols with isoquinolines or pyridines. The transformation proceeded readily in the presence of a com. available CuCl2 catalyst with mol. oxygen as a green oxidant. Moreover, the dehydrogenative cross-coupling of 2-aminoarylmethanols with tetrahydroisoquinolines were explored, in which CuBr exhibited higher catalytic activity than CuCl2. Broad substrate scope with good tolerance of functionalities were observed under the optimized reaction conditions. The bioactive naturally occurring alkaloid rutaecarpine was obtained by this strategy. The remarkable feature of this protocol was that complicated heterocyclic structures were readily achieved in a single synthetic step from easily accessible reactants and catalysts. The pathway to pyrido-fused quinazolinones would be complementary to existing protocols.

Yang, Dong; von Krbek, Larissa K. S.; Yu, Le; Ronson, Tanya K.; Thoburn, John D.; Carpenter, John P.; Greenfield, Jake L.; Howe, Duncan J.; Wu, Biao; Nitschke, Jonathan R. published the artcile< Glucose Binding Drives Reconfiguration of a Dynamic Library of Urea-Containing Metal-Organic Assemblies>, Application In Synthesis of 4064-06-6, the main research area is iron urea functionalized ditopic formylpyridine helicate preparation crystal structure; host guest binding activity inclusion iron helicate saccharide mutarotation; dynamic combinatorial library; glucose binding; host-guest systems; metal-organic assemblies; supramolecular chemistry.

A bis-urea-functionalized ditopic subcomponent assembled with 2-formylpyridine and FeII, resulting in a dynamic library of metal-organic assemblies: an irregular FeII4L6 structure and three FeII2L3 stereoisomers: left- and right-handed helicates and a meso-structure. This library reconfigured in response to the addition of monosaccharide derivatives, which served as guests for specific library members, and the rate of saccharide mutarotation was also enhanced by the library. The (P) enantiomer of the FeII2L3 helical structure bound β-D-glucose selectively over α-D-glucose. As a consequence, the library collapsed into the (P)-FeII2L3 helicate following glucose addition The α-D-glucose was likewise transformed into the β-D-anomer during equilibration and binding. Thus, β-D-glucose and (P)-3 amplified each other in the product mixture, as metal-organic and saccharide libraries geared together into a single equilibrating system.

The objective of this study was to investigate the effects of four com. lactic acid bacteria (LAB), namely L. acidophilus, L. casei, L. helveticus and L. plantarum, on the phenolic profiles, antioxidant capacities and flavor profiles of jujube juices prepared from two crop varieties (Ziziphus Jujuba cv. Muzao and Hetian). Results showed that both jujube juices were excellent matrixes for LAB growth with more than 11 log CFU/mL of viable counts at the end of fermentation LAB fermentation dramatically increased total phenolic content, while decreased total flavonoid content of jujube juices. However, antioxidant capacities based on DPPH and FRAP methods were significantly improved by LAB fermentation and pos. correlated with caffeic acid and rutin contents. Furthermore, a total of 74 volatile compounds were identified and increased in total content by LAB fermentation, which resulted in 22 and 19 new flavor volatiles formation in Muzao juice and Hetian juice, resp.

Komorowska, Justyna; Wątroba, Mateusz; Szukiewicz, Dariusz published the artcile< Review of beneficial effects of resveratrol in neurodegenerative diseases such as Alzheimer's disease.>, COA of Formula: C14H12O3, the main research area is Alzheimer’s disease; Antioxidation; Central nervous system; Polyphenols; Resveratrol.

PURPOSE: The prevalence of Alzheimer’s Disease is rising, in part due to increase in the medium age of residents in developed countries. The aim of the study has been to determine whether resveratrol (RSV) can be effective in the prevention or treatment of Alzheimer’s Disease, providing its antioxidant, anti-inflammatory, and SIRT1-activating properties. METHODS: A systematic review of some experimental and clinical studies has been made. The eligibility criteria have comprised: maximum 10 years passed from the study publication, geographical diversity of the studies performed, and – as much as possible – pertaining of the reviewed study results both to animal models of AD, and to humans. RESULTS: After the final assessment of the eligibility criteria, 96 research studies have been included in the review. Overall results suggest that RSV can be effectively used in the prevention of AD, especially in reference to its familial forms with an early onset. At the same time, efficacy of RSV in the treatment of AD needs further studies, aimed at: improving its transport through the blood-brain barrier (BBB), performing prospective clinical in vivo trials on large groups of patients, and determining the optimal RSV dosage. DISCUSSION: Providing RSV mechanisms of action, inhibitory in reference to many pathomechanisms of AD, it seems very likely that RSV could be effective in AD prevention. The main limitations referring to such presumption include: limited permeability of BBB to RSV, and scarcity of clinical studies on RSV pertaining to large groups of humans.

Sun, Xiao-Ying; Dong, Quan-Xiu; Zhu, Jie; Sun, Xun; Zhang, Li-Fan; Qiu, Mandy; Yu, Xiao-Lin; Liu, Rui-Tian published the artcile< Resveratrol Rescues Tau-Induced Cognitive Deficits and Neuropathology in a Mouse Model of Tauopathy>, COA of Formula: C14H12O3, the main research area is resveratrol tau cognitive deficit neuropathol tauopathy; Alzheimer’s disease; Resveratrol; neuroinflammation; oligomer; synapse loss; tau..

Background: Alzheimer’s Disease (AD) is characterized by the presence of extracellular amyloid-β (Aβ) plaques and intraneuronal neurofibrillary tangles assembled by the microtubuleassocd. protein tau. Increasing evidence demonstrated that tau pathol. played an important role in AD progression. Resveratrol (RSV) has previously proved to exert neuroprotective effect against AD by inhibiting Aβ generation and Aβ-induced neurocytotoxicity, while its effect on tau pathol. is still unknown. Methods: The effect of RSV on tau aggregation was measured by Thioflavin T fluorescence and Transmission electron microscope imaging. The effect of RSV on tau oligomer-induced cytotoxicity was assessed by MTT assay and the uptake of extracellular tau by N2a cells was determined by immunocytochem. 6-mo-old male PS19 mice were treated with RSV or vehicle by oral administration (gavage) once a day for 5 wk. The cognitive performance was determined using Morris water maze test, object recognition test and Y-maze test. The levels of phosphorylated-tau, gliosis, proinflammatory cytokines such as TNF-α and IL-1β, and synaptic proteins including synaptophysin and PSD95 in the brains of the mice were evaluated by immunoblotting, immunostaining and ELISA, resp. Results: RSV significantly inhibited tau aggregation and tau oligomer-induced cytotoxicity, and blocked the uptake of extracellular tau oligomers by N2a cells. When applied to PS19 mice, RSV treatment effectively rescued cognitive deficits, reducing the levels of phosphorylated tau, neuroinflammation and synapse loss in the brains of mice. Conclusion: These findings suggest that RSV has promising therapeutic potential for AD and other tauopathies.
