An expanded library of matrix assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) has been constructed using the spectra generated from 42 clinical isolates and 11 reference strains, including 23 different species from 8 sections (16 cryptic plus 7 noncryptic species). Out of a total of 379 strains of Aspergillus isolated from clinical samples, 179 strains were selected to be identified by sequencing of beta-tubulin or calmodulin genes. Protein spectra of 53 strains, cultured in liquid medium, were used to construct an in-house reference database in the MALDI-TOF MS...

How rootstocks contribute to the control of scion transpiration under drought is poorly understood. We investigated the role of root characteristics, hydraulic conductance and chemical signals (abscisic acid, ABA) in the response of stomatal conductance (gs) and transpiration (E) to drought in Cabernet Sauvignon (Vitis vinifera) grafted onto drought-sensitive (Vitis riparia) and drought-tolerant (Vitis berlandieri × Vitis rupestris 110R) rootstocks. All combinations showed a concomitant reduction in gs and E, and an increase in xylem sap ABA concentration during the drought cycle...

The mammalian oviduct is the place where life begins as it is the site of fertilization and preimplantation embryo development. Recent research has highlighted the important role played by the oviduct both in sperm selection for natural fertilization and in the genetic and epigenetic reprogramming of pre-implantation embryo development. This review examines oviduct fluid composition with a special emphasis on exosomes and the role played by the oviduct in sperm selection, early embryo development, and in reshaping the epigenetic landscape of the embryo...

BACKGROUND: The diagnostic power of CT or MRI on the lymph node status was limited. Supplement measurements were needed to assist the diagnosis of lymph node metastasis. The SCCa was reported to be close related to lymph node status. But currently the clinical value of serum SCCa measurement in lymph node status has not been clearly defined. This meta-analysis was to investigate this topic on a large scale. METHOD: Searching the Pubmed, Embase, Cochrane library, CNKI and Wanfang database for SCC-Ag/SCCA/SCC-antigen and cervical cancer/tumor/carcinoma/neoplasm published in any language from Jan 1 1990 to Aug 1 2017...

BACKGROUND: The evidence in favor of exercise as a treatment for depression is compelling, but what kind of exercise, how much, how often, and at what intensity is necessary to make a significant difference. There is serious dearth of such data from India, in particular. We examined the impact of low-moderate intensity aerobic exercises on mood and somatic symptoms among women with depressive disorders. METHODS: A pre test- post test control group design was adopted with a sample size of 40 (20 subjects randomized to both experimental and control group) women inpatients diagnosed with depressive disorder at a tertiary care centre, Bengaluru, India...

Peach is an important deciduous fruit tree species. Anthocyanins play an important role in fruit color formation and, through linkage analysis, previous studies have identified and mapped the key genes regulating anthocyanins' accumulation to chromosomes 3 and 5 in two different germplasms. To understand the overall regulatory network of anthocyanins biosynthesis, genes co-expressed with these key genes were identified in the red-fleshed 'Tianjin Shui Mi' and white-fleshed 'Hakuho' germplasms. Analysis of their flesh anthocyanin contents revealed differences 15 days before maturation...

In this work, the novel ternary AgBr/Ag/PbBiO2Br Z-scheme photocatalysts were synthesized via a CTAB-assisted calcination process. The AgBr/Ag/PbBiO2Br composites were employed for the degradation of rhodamine B (RhB) and antibiotic bisphenol A (BPA) under visible light irradiation. Results showed that the obtained AgBr/Ag-3/PbBiO2Br displayed optimal photocatalytic performance, which could remove almost all RhB within 25 min and effectively decompose 82.3% of BPA in 120 min. Three-dimensional excitation-emission matrix fluorescence spectra (3D EEMs) were utilized for the purposes of fully grasping the behaviors of RhB molecules during the reaction process...

This paper draws from Hägerstrand's space-time framework to generate new insights on the everyday mobilities of individuals with visual impairments in the San Francisco Bay Area. While existing research on visual impairment and mobility emphasizes individual physical limitations resulting from vision loss or inaccessible public spaces, this article highlights and bridges both the behavioral and social processes that influence individual mobility. A qualitative analysis of sit-down and mobile interview data reveals that the space-time constraints of people with visual impairments are closely linked to their access to transportation, assistive technologies, and mobile devices...

While the presence of iron is generally not seen as favorable for UV-based treatment systems due to lamp fouling and decreased UV transmittance, we show that low levels of iron can lead to improvements in the abatement of chemicals in the UV-hydrogen peroxide advanced oxidation process. The oxidation potential of an iron-assisted UV/H2O2 (UV254 + H2O2 + iron) process was evaluated at neutral pH using iron levels below USEPA secondary drinking water standards (<0.3 mg/L). Para-chlorobenzoic acid (pCBA) was used as a hydroxyl radical (HO) probe to quantify HO steady state concentrations...

Untreated age-related macular degeneration (AMD), diabetic retinopathy (DR), and glaucoma may lead to irreversible vision loss. Hence, it is essential to have regular eye screening to detect these eye diseases at an early stage and to offer treatment where appropriate. One of the simplest, non-invasive and cost-effective techniques to screen the eyes is by using fundus photo imaging. But, the manual evaluation of fundus images is tedious and challenging. Further, the diagnosis made by ophthalmologists may be subjective...

AIMS: Esophageal squamous cell carcinoma (ESCC) is characterized by high prevalence and mortality worldwide, and it is very highly prevalent in China. ESCC is caused by various factors, including microRNAs (miRNAs) whose expression have been shown to play a major role in tumor generation. Single nucleotide polymorphisms (SNPs) in miRNAs could affect susceptibility to numerous cancers. This study aimed to evaluate the relationship between SNPs in miR-124 and ESCC risk in the Chinese Kazakh population...

Dynamic assembly of actin filaments is essential for many cellular processes. The rates of assembly and disassembly of actin filaments are intricately controlled by regulatory proteins that interact with the ends and the sides of filaments and with actin monomers. TIRF-based single-filament imaging techniques have proven instrumental in uncovering mechanisms of actin regulation. In this unit, novel single-filament approaches using microfluidics-assisted TIRF imaging are described. These methods can be used to grow anchored actin filaments aligned in a flow, thus making the analysis much easier as compared to open flow cell approaches...

We report a systematic investigation on the role of excess PbI2 content in CH3NH3PbI3 perovskite film properties, solar cell parameters and device storage stability. We used the CH3NH3I vapor assisted method for the preparation of PbI2-free CH3NH3PbI3 films under a N2 atmosphere. These pristine CH3NH3PbI3 films were annealed at 165 °C for different time intervals in a N2 atmosphere to generate additional PbI2 in these films. From XRD measurements, the excess of PbI2 was quantified. Detailed characterization using scanning electron microscopy, X-ray diffraction, UV-Visible and photoluminescence for continuous aging of CH3NH3PbI3 films under ambient condition (50% humidity) is carried out for understanding the influence of different PbI2 contents on degradation of the CH3NH3PbI3 films...
