Rhizoma et Radix Polygoni Cuspidati (RRPC) is commonly prescribed for the treatments of amenorrhea, arthralgia, jaundice and abscess in traditional Chinese medicine. Previous pharmacological studies have indicated that polyphenols are the main pharmacological active ingredients in RRPC. Meanwhile, the poor bioavailability of polyphenols in RRPC implies that those components are probably metabolized by intestinal bacteria before absorption. However, there is rather limited information about RRPC's metabolites produced by intestinal bacteria and the intestinal absorbed constituents...

Triple negative breast cancer (TNBC) is a heterogenous disease with high aggressive and poor outcome. The lack of biomarkers and targeted therapies makes it a challenge for the treatment of TNBC. Histone deacetylase inhibitors (HDACis) are emerging as novel anti-tumor agents in many types of human cancers. In this study, we found that I-7ab, a novel HDACi, inhibited the cell viability of TNBC cells and induced the cell apoptosis. Mechanistically, I-7ab specifically decreased the expression of HDAC3 and promoted the acetylation of p53 at both Lys373 and Lys382 amino acids...

INTRODUCTION: Bone remodeling relies on a delicate balance between formation and resorption of bone tissues, processes in which bone-forming osteoblasts and bone-resorbing osteoclasts play central roles. Recently, we reported that anticoagulant activated protein C (APC) promotes osteoblast proliferation, but the role of the blood coagulation system in bone remodeling remains unclear. In this study, to further elucidate the relationship between bone remodeling and blood coagulation, we investigated the effect of APC on osteoclast differentiation...

OBJECTIVES: Language is an important human function, and is a determinant of the quality of life. In conditions such as brain lesions, disruption of the language function may occur, and lesion resection is a solution for that. Presurgical planning to determine the language-related brain areas would enhance the chances of language preservation after the operation; however, availability of a normative language template is essential. PATIENTS AND METHODS: In this study, using data from 60 young individuals who were meticulously checked for mental and physical health, and using fMRI and robust imaging and data analysis methods, functional brain maps for the language production, perception and semantic were produced...

LGD-4033 has been found in human doping control samples and has the potential for illicit use in racehorses as well. It belongs to the pharmacological class of selective androgen receptor modulators (SARMs) and can stimulate muscle growth, much like anabolic steroids. However, SARMs have shown superior side effect profiles compared to anabolic steroids, which arguably makes them attractive for use by individuals seeking an unfair advantage over their competitors. The purpose of this study was to investigate the metabolites formed from LGD-4033 in the horse in order to find suitable analytical targets for doping controls...

Skin fibroblasts were collected from a 44-year-old patient with sporadic case of Parkinson's disease (PD). The non-integrating Sendai virus vector encoding OCT3/4, SOX2, c-MYC and KLF4 was used to reprogram fibroblasts into induced pluripotent stem cells (iPSCs). Generated iPSCs had normal karyotypes, expressed common stem cell markers, and were capable of differentiating into all three germ layers. Generated line could be used for PD modeling to understand the mechanisms that influence the disorder.

Joubert Syndrome (JS) is a rare autosomal recessive or X-linked condition characterized by a peculiar cerebellar malformation, known as the molar tooth sign (MTS), associated with other neurological phenotypes and multiorgan involvement. JS is a ciliopathy, a spectrum of disorders whose causative genes encode proteins involved in the primary cilium apparatus. In order to elucidate ciliopathy-associated molecular mechanisms, human induced pluripotent stem cells (hiPSCs) were derived from a patient affected by JS carrying a homozygous missense mutation in the AHI1 gene (p...

Health-optimum-exposure index (HOEI) is proposed to assess if the prescribed amount of vitamin D3 (target value) could be synthesized in the human skin without erythema appearance. It is defined as the ratio between the vitamin D3 quantity received during the maximum allowed outdoor exposure without erythema risk and the target value. Sunbathing is safe for HOEI>1 and 1/HOEI represents a part of minimal erythema dose (MED) necessary to obtain the target value. We examine the following targets: a vitamin D3 quantity equivalent to 1000 IU vitamin D3 taken orally, and an optimal vitamin D3 quantity defined by Krzyścin et al...

Taurine, a β-amino acid that is abundantly available in the tissues of human and animals, is efficiently used as a green bio-organic catalyst in the preparation of some of the biologically active barbituric and thiobarbituric acid derivatives. In the presence of taurine, 5-Arylidene (thio) barbituric acid derivatives were prepared via Knovenagel reaction between aldehydes and (thio)barbituric acid. Using this reagent also pyrano[2,3-d]pyrimidinone(thione) derivatives were synthesized through a three-component reaction between aldehydes, (thio)barbituric and malononitrile...

RATIONALE: A novel benzimidazole compound ZLN005 was previously identified as a transcriptional activator of peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α) in certain metabolic tissues. Upregulation of PGC-1α by ZLN005 has been shown to have beneficial effect in a diabetic mouse model and in a coronary artery disease model in vitro. ZLN005 could also have therapeutic potential in neurodegenerative diseases involving down-regulation of PGC-1α. Given the phenotypic efficacy of ZLN005 in several animal models of human disease, its metabolic profile was investigated to guide the development of novel therapeutics using ZLN005 as the lead compound...

To determine the warping angle of the costal cartilage in vivo. A nasal framework reconstruction with a rib graft was performed in a total of 130 patients. After the cartilage specimens were prepared, the remaining grafts were used for the experimental study. The angle of warping in all grafts was measured at 0, 30, and 60 minutes, after 24 hours and after one week. In this study, 8 subgroups of graft thicknesses from central and peripheral groups, which were determined according to the perichondral distance of the grafts, were evaluated, and the warping angles of a total of 48 osteochondral and chondral grafts were individually measured...

BACKGROUND: The apoptosis of mature adipocytes after fat grafting can result in chronic inflammation, absorption, and fibrosis, leading to unpredictable outcomes. Selective elimination of mature adipocytes may result in better outcomes and a different underlying retention mode. We previously developed a mature-adipocyte-free product, SVF-gel, derived from lipoaspirate, which eliminates adipocytes while preserving the stromal vascular fraction. This study investigated the retention and regeneration mode of SVF-gel grafting...

BACKGROUND: Identification of the lymphatic system in cadavers is painstaking because lymphatic vessels have very thin walls and are transparent. Selection of appropriate contrast agents is a key factor for successfully visualizing the lymphatics. In this study, we introduce a new imaging technique of lymphatic mapping in whole body of fresh cadavers. METHODS: Ten fresh human cadavers were used for this study. We injected 0.1 mL of indocyanine green fluorescence (ICG) solution subcutaneously at multiple spots along the watershed lines between lymphatic territories and hand and foot regions...
