TWO new disulfide-bonded collagenous pepsin-&rived fragments have been isolated from chick embryo tendons. These fragments represent less than 0.5% of the pepsin-extractable collagen. We purified 10and 16-kDa reduced fragments derived, respectively, from 32and 46-kDa disulfide-bonded fragments. Unique tryptic peptide maps were obtained for each fragment. Although these collagenous fragments dif...

Tropical dry forests (TDFs) have been widely transformed by human activities worldwide and the ecosystem services they provide are diminishing. There has been an urgent call for conservation and restoration of the degraded lands previously occupied by TDFs. Restoration experiences aim to recover species diversity and ecological functions. Different restoration strategies have been used to maxim...

Aim To analyse the biogeographic patterns of Temperate Deciduous Forests (TDFs) in Western Eurasia based on different life-forms and forests layers explore their relationships with current climate, Last Glacial Maximum (LGM) climate topography. Location Eurasia. Taxon Vascular plants. Methods We delimited nine regions encompassing variability TDFs collected 1000 vegetation plots from each. deco...

Detections of the tidal disruption flares (TDFs) stars by supermassive black holes (SMBHs) are rapidly accumulating as optical surveys improve. These detections may provide constraints on SMBH demographics, stellar dynamics, and evolution in galaxies. To maximize this scientific impact, we require a better understanding how astrophysical parameters interact with survey selection effects setting...

OBJECTIVE Aberrant splicing is one of the most significant components generating functional diversity in many pathological conditions. The objective of this study was to analyse the mutations or aberrant splicing of A20 transcript, the region encompassing the ovarian tumour (OTU) domain [which is functionally important as an inhibitor of nuclear factor (NF)-κB activation] in fibroblast-like syn...

Ischemic injuries will lead to necrotic tissue damage, and post-ischemia angiogenesis plays critical roles in blood flow restoration and tissue recovery. Recently, several types of small RNAs have been reported to be involved in this process. In this study, we first generated a rat brain ischemic model to investigate the involvement of new types of small RNAs in ischemia. We utilized deep seque...

Heavy metals pollution is one of the key environmental problems. In this research, the effect of seed priming with salicylic acid and sodium hydrosulfide was investigated on methionine and arginine amino acids contents and some compounds derived from their metabolism as well as ZmACS6 and ZmSAMD transcripts levels in maize plants under lead stress. For this purpose, maize seeds were soaked in s...

Extracellular vesicles (EVs) have been proposed as a means to promote intercellular communication. We show that when human primary cells are exposed to cancer cell EVs, rapid cell death of the primary cells is observed, while cancer cells treated with primary or cancer cell EVs do not display this response. The active agents that trigger cell death are 29- to 31-nucleotide (nt) or 22- to 23-nt ...

The non-human primate reference transcriptome resource (NHPRTR, available online at http://nhprtr.org/) aims to generate comprehensive RNA-seq data from a wide variety of non-human primates (NHPs), from lemurs to hominids. In the 2012 Phase I of the NHPRTR project, 19 billion fragments or 3.8 terabases of transcriptome sequences were collected from pools of ∼ 20 tissues in 15 species and subspe...
