This study proposes the description of the development of the post-cranial axial skeleton, including vertebrae, gastralium, ribs, sternum and interclavicle, in Melanosuchus niger. Six nests were marked and two eggs removed from each nest at 24-hour intervals until hatching. For post-hatching evaluation, 30 hatchlings were kept in captivity and one exemplar was euthanized at three-day intervals. Samples were diaphanized using potassium hydroxide (KOH), alizarin red S and Alcian blue. A routinely generally used method was applied for histological evaluation...

BACKGROUND/PURPOSE: While growing evidence supports the therapeutic effect of 453 nm blue light in chronic inflammatory skin diseases, data on its effects on acutely-perturbed human skin are scarce. In this study we investigated the impact of 453 nm narrow-band LED light on healthy skin following acute perturbation. METHODS: Tape stripping and histamine iontophoresis were performed on the forearm of 22 healthy volunteers on two consecutive weeks. In one week, challenges were followed by irradiation for 30 minutes...

Inhibition of amyloid formation along with modulation of toxicity employing small molecules is emerging as a potential therapeutic approach for protein misfolding disorders which includes Parkinson's disease, Alzheimer's disease and Multiple System Atrophy etc. Countless current interventional strategies for treating α-synucleinopathies consider using peptidic and non-peptidic inhibitors for arresting fibrillisation, disrupting existing fibrils and reducing associated toxicity. One group of molecules less exploited in this regard are triphenylmethane dyes...

At present there is no therapy for Alzheimer's Disease which completely stops the progressive dementia effecting late onset Alzheimer's Disease (AD) patients. It is felt that the main reason for this failure is that AD appears to be a disease caused by four major pathological processes. To date, efforts to develop treatments have addressed only one or another of these four etiologies. However, even a partially effective therapy against one cause allows the others, untreated, to continue their inexorable destruction of the neurons of the brain...

BACKGROUND: The simultaneous exposure to blue and green light was reported to result in less melatonin suppression than monochromatic exposure to blue or green light. Here, we conducted an experiment using extremely short blue- and green-pulsed light to examine their visual and nonvisual effects on visual evoked potentials (VEPs), pupillary constriction, electroretinograms (ERGs), and subjective evaluations. METHODS: Twelve adult male subjects were exposed to three light conditions: blue-pulsed light (2...

BACKGROUND: The identification of microorganisms with excellent flocculant-producing capability and optimization of the fermentation process are necessary for the wide-scale application of bioflocculants. Thus, we evaluated the flocculant-producing ability of a novel strain identified by the screening of marine bacteria, and we report for the first time the properties of the bioflocculant produced by Alteromonas sp. in the treatment of dye wastewater. RESULTS: A bioflocculant-producing bacterium was isolated from seawater and identified as Alteromonas sp...

As double-muscled Belgian Blue (BB) and Piemontese (PIEM) breeds are heavily selected for different objectives (the former mainly for muscularity, the latter for ease of calving), the aim of this study was to compare sexual dimorphism in 56 crossbred young bulls and heifers obtained from dairy cows mated to bulls of the two beef breeds. Young PIEM- and BB-sired bulls had similar fattening performances and beef traits, although the BB crossbreds were slightly more muscular. Otherwise, the BB-sired heifers exceeded the PIEM-sired heifers in growth rate (1...

We demonstrate a novel molecular design concept for thermally activated delayed fluorescence (TADF) polymers based on a nonconjugated polyethylene backbone with through-space charge transfer effect between pendant electron donor (D) and electron acceptor (A) units. Different from conventional conjugated D-A polymers with through-bond charge transfer effect, the nonconjugated architecture avoids the direct conjugation between D and A units, enabling us to realize blue emission. Meanwhile, the spatial π-π interaction between the physically separated D and A units results in both small singlet-triplet energy splitting (0...

Saposhnikoviae radix (SR) is described in the Japanese Pharmacopoeia as a crude drug derived from the root of Saposhnikovia divaricata Schischkin (Umbelliferae). According to Flora of China, the root of Peucedanum ledebourielloides K. F. Fu is used as a regional substitute for SR. Therefore, we surveyed the botanical origin of the drug used in China, especially Shaanxi and the surrounding regions, through nucleotide sequence analysis of the internal transcribed spacer region of rDNA. As a result, several samples from Shaanxi () and Shanxi () provinces were identified as Peucedanum ledebourielloides...

The success of many endosseous implants in orthopaedic and dental applications depends on the surface characteristics, as they affect osseous integration. Previous investigations indicated that a novel large-grit sand-blasted and acid-etched (SLA) titanium (denoted as SLAffinity-Ti) implant had better bone integration than that of a comparably shaped implant with a plasma-sprayed titanium surface. The purpose of the present investigation was to create a SLAffinity surface on pedicle screws and trauma screws and to compare it with the surfaces of a sand-blasted-only implant and commercial implants in terms of bone integration...

Mn(4+)-activated hexafluoroaluminates are promising red-emitting phosphors for white light emitting diodes (w-LEDs). Here, we report the synthesis of Na₃AlF₆:Mn(4+), K₃AlF₆:Mn(4+) and K₂NaAlF₆:Mn(4+) phosphors through a simple two-step co-precipitation method. Highly monodisperse large (~20 μm) smoothed-octahedron shaped crystallites are obtained for K₂NaAlF₆:Mn(4+). The large size, regular shape and small size distribution are favorable for application in w-LEDs. All Mn(4+)-doped hexafluoroaluminates show bright red Mn(4+) luminescence under blue light excitation...

The reaction of 2-hydroxyl-4-carboxylbenzenesulfonic acid (H3L) and rare earth (RE) metal nitrates together with two N-heterocyclic ligands gives rise to the formation of 38 complexes, namely, [La(H2L)2(ox)0.5(H2O)4]n·2nH2O (1-La) (ox = oxalate), [RE2(H2L)2 (ox)(H2O)12]·2(H2L)·8H2O (2-RE) (RE = Nd, Sm, Eu, Gd, Tb, Dy), [RE(SO4)(H2O)7]·(H2L)·3H2O (3-RE) (RE = Ho, Er, Tm, Yb, Lu and Y), [RE(L)(H2O)3]n·nH2O (4-RE) (RE = Er, Tm, Yb and Lu), [RE(L)(2,2'-bipy)(H2O)]n (5-RE) (RE = La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho and Y, 2,2'-bipy = 2,2'-bipyridine), [RE(L)(1,10-phen)(H2O)]n (6-RE) (RE = La, Pr, Nd, Sm, Eu, 1,10-phen = 1,10-phenanthroline), and [RE(L')(1,10-phen)2(H2O)]n (7-RE) (RE = Gd, Tb, Ho, Er, Yb and Lu, H3L' = 2-hydroxy-3-nitro-4-carboxybenzenesulfonic acid), which have been characterized by elemental analysis, IR, TG, PL, powder and single-crystal X-ray diffraction...

Intense white light emission is observed from colloidal single component NaYF4:Ce3+/Tm3+/Mn2+ nanocrystals. This combination is interesting as it uses Mn2+ ions instead of green and red emitting Ln3+ ions which are expensive and less abundant. The single band blue emission of Tm3+ ions was combined with the broadband greenish yellow emission of Mn2+ ions to produce strong white light emission using Ce3+ ions as excitation source. Interestingly, there is hardly any re-absorption of blue emission by Mn2+ ions and the spectrum matches the commercial Ce3+-doped YAG phosphor coated over blue LED...

Merkel cell carcinoma (MCC) is a rare, clinically aggressive, cutaneous neuroendocrine (NE) neoplasm. As a tumor with small, round, blue cells, the histologic differential diagnosis for MCC can include melanoma, metastatic small cell carcinoma (SCC), nodular hematopoietic tumors, basal cell carcinoma (BCC), atypical variants of squamous carcinoma, and the uncommon occurrence of primary cutaneous Ewing sarcoma. In cases with atypical histology or without the classic immunophenotype the diagnosis can be challenging...

INTRODUCTION: Hemodialysis (HD) is an expensive therapy in economic and in ecological terms, owing to a high carbon footprint and significant consumption of natural sources, especially water. Our aim was to review strategies to diminish waste of water in maintenance dialysis, exploring previously described water reuse trends and less known strategies for reducing the dialysate flow. METHODS: We conducted a systematic review of water-sparing strategies, including the reuse of reverse osmosis rejected water and the reduction of dialysate flux...

Being short of conventional chromophores, polyacrylamide is generally not regarded as a fluorescent material. Exactly the polymerization of dilute solutions of acrylamide and N,N'-methylenebisacrylamide led to thick liquids at 60 °C, showing no fluorescence. Things changed when the phase transition of water was involved. The squeezing effect of ice crystals not only created polymeric solids (cryogels) at - 20 °C, but also endowed them unexpected fluorescence emissions. The macroporous cryogels are mainly blue fluorescent polymers...

The sensitivity of human melanoma cells to photoactivated Hypericin (Hyp) compared to aluminium(III) phthalocyanine chloride tetrasulphonate (AlPcS4Cl) is reported in this study. Melanoma cells (A375 cell line) were treated with various concentrations of Hyp or AlPcS4Cl alone, for 1, 4, and 24 hrs; varying doses of laser irradiation alone (594 or 682 nm); or optimal concentrations of PSs combined with laser irradiation. Changes in cell morphology, viability, membrane integrity, and proliferation after treatment of cells were determined using inverted microscopy, Trypan blue cell exclusion, Lactate Dehydrogenase (LDH) membrane integrity, and adenosine triphosphate (ATP) cell proliferation assay, respectively...

The flowers of flax (linseed) are blue-hued, ephemeral and self-pollinating, and the seeds are typically brown. A century-old interest in natural yellow seed variants and a historical model point to recessive alleles in B1, D and G loci being responsible, but the functional aspects had remained unknown. Here, we characterized the "D" locus by quantitative trait loci (QTL) mapping and identified a FLAVONOID 3'5' HYDROXYLASE (F3'5'H) gene therein. It does not belong to the F3'5'H clade, but resembles biochemically characterized F3'Hs (flavonoid 3' hydroxylase) but without F3'H activity...
