129I in natural archives, such as ice cores, can be used as a proxy for human nuclear activities, age marker, and environmental tracer. Currently, there is only one published record of 129I in ice core (i.e., from Fiescherhorn Glacier, Swiss Alps) and its limited time resolution (1-2 years) prevents the full use of 129I for the mentioned applications. Here we show 129I concentrations in an ice core from SE-Dome, Greenland, covering years 1956-1976 at a time resolution of ∼6 months, the most detailed record to date...

Nanozymes have been extensively exploited in the construction of colorimetric sensors in the past decade. However, as lack of specific recognition element, these sensors are mostly limited in the detection of hydrogen peroxide and its related agents. In this work, a colorimetric assay for the detection of alkaline phosphatase (ALP) activity was developed by employing copper (II)-based metal-organic frameworks (Cu-MOFs) as peroxidase mimic and pyrophosphate (PPi) as recognition element. Benefiting from its intrinsic porosity, Cu-MOFs built from one-step self-assembly showed a superior catalytic activity over horseradish peroxidase...

Several groups have reported the important role of estradiol (E2) and testosterone (T) in postmenopausal osteoporosis (PMOP). Because aromatase catalyzes the conversion of T to E2, the purpose of this study was to determine the influence of aromatase activity on the bone mineral density (BMD) in postmenopausal women. A total of 344 postmenopausal women were selected for this study. Serum E2, T, sex hormone-binding globulin (SHBG), calcium (Ca), alkaline phosphatase (ALP), C-terminal telopeptide of type I collagen (CTX), and procollagen type I amino-terminal propeptide (PINP) were examined...

A major limitation of existing 3D implantable structures for bone tissue engineering is that most of the cells rapidly attach on the outer edges of the structure, restricting the cells penetration into the inner parts and causing the formation of a necrotic core. Furthermore, these structures generally possess a random spatial arrangement and do not preserve the isotropy on the whole volume. Here, we report on the fabrication and testing of an innovative 3D hierarchical, honeycomb-like structure (HS), with reproducible and isotropic arhitecture, that allows "in volume" migration of osteoblasts...

In this study, we investigated the mechanism underlying age-related susceptibility in broilers to aflatoxin B1 (AFB1). The results showed that AFB1 induced significant changes in serum alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT) activity & liver superoxide dismutase (SOD), malonaldehyde (MDA), glutathione peroxidase (GSH-Px) and glutathione S-transferase (GST) activity at day 7, 21 and 42 relative to control group. However, AFB1-induced changes in serum biochemical parameters and liver antioxidant activities becomes less severe with increasing age of broilers...

Considering the complex hierarchical structure of bone, biomimicking the micro and nano level features should be an integral part of scaffold fabrication for successful bone regeneration. We aim to biomimic the micro- and nano-structure of bone and study the effect of physical cues on cell alignment, proliferation and differentiation. To achieve this, we have divided the scaffolds into groups: electrospun SU-8 nanofibers, electrospun SU-8 nanofibers with UV treatment and micropatterned (20 μm sized ridges and grooves) SU-8 nanofibers by photolithography with UV treatment...

HPC 03 is herbal formula that consists of extracts from Angelica gigas, Cnidium officinale Makino and Cinnamomum cassia Presl. The present study evaluated the estrogenic potential of HPC 03 by using in vitro and in vivo models. The regulatory mechanisms of HPC 03 in estrogen-dependent MCF-7 cells were assessed. HPC 03 induced the proliferation of estrogen receptor-positive MCF-7 cells, and the proliferation was blocked by the addition of the estrogen antagonist tamoxifen. The estrogen receptorα/β luciferase activities were significantly increased by HPC 03 treatment, which also increased the mRNA expression of the estrogen-responsive genes Psen2, Pgr and Ctsd Also, we evaluated the ameliorative effects of HPC 03 on menopausal symptoms in ovariectomized rats...

A new bone augmenting material is reported, which is formed from calcium-loaded hydrogel-based spheres. On immersion of these spheres in a physiological medium, they become surrounded with a sheath of precipitate, which ruptures due to a build-up in osmotic pressure. This results in the formation of mineral tubes that protrude from the sphere surface. When brought into close contact with one another, these spheres become fused through the entanglement and subsequent interstitial mineralization of the mineral tubules...

Papain-like cysteine proteases (PLCPs) are a class of proteolytic enzymes involved in many plant processes. Compared with the extensive research in Arabidopsis thaliana, little is known in castor bean (Ricinus communis) and physic nut (Jatropha curcas), two Euphorbiaceous plants without any recent whole-genome duplication. In this study, a total of 26 or 23 PLCP genes were identified from the genomes of castor bean and physic nut respectively, which can be divided into nine subfamilies based on the phylogenetic analysis: RD21, CEP, XCP, XBCP3, THI, SAG12, RD19, ALP and CTB...

Few pooled analyses of antiresorptive (AR) treatment trials relate short-term changes in bone turnover markers (BTMs) to subsequent fracture reduction. Such information would be useful to assess new ARs or novel dosing regimens. In the Foundation for the National Institutes of Health (FNIH) Bone Quality project, we analyzed individual-level data from 28,000 participants enrolled in 11 bisphosphonate (BP) and three selective estrogen receptor modulator (SERM) placebo-controlled fracture endpoint trials. Using BTM results for two bone formation markers (bone-specific alkaline phosphatase [bone ALP] and pro-collagen I N-propeptide [PINP]) and two bone resorption markers (N-terminal and C-terminal telopeptide of type I collagen) and incident fracture outcome data, we performed a meta-regression relating the mean net effect of treatment on change in bone turnover (active minus placebo % difference after 3 to 12 months) to the log of study-wide fracture risk reduction, and used linear regression to plot the best fitting line...
