A robust superamphiphobic sponge (SA-sponge) is proposed by using a single initiated chemical vapor deposition (i-CVD) process. Poly(3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-heptadecafluorodecyl methacrylate) (PFDMA) is deposited on a commercial sponge by the polymerization of fluoroalkyl acrylates during the i-CVD process. This PFDMA is conformally coated onto both the exterior and interior of the...

Objective: The aim of this study was to explore the effect of endothelial progenitor cells (EPCs)-collagen sponge complex on the neovascularization of chronic cerebral ischemia following multiple burr hole (MBH) surgery. Methods: Bone marrow-derived EPCs from 5 Fisher 344 (F344) inbred rats were cultured and amplified in vitro, then co-cultured to become the EPCs-collagen sponge complex. Chroni...

Titanium has excellent all-round performance, but the high cost of its production limits widespread use. Currently, Kroll process used to commercially produce titanium sponge is inefficient, energy-intensive, and highly polluting environment. Over past few decades, many new processes have been developed replace in order reduce producing make it a common metal with as applications iron. These ca...

This experiment was carried out on 123 Farahani ewes from a herd in Delijan city in Markazi province of Iran to determine the best short-term method for oestrus synchronization. Ewes were divided into five experimental groups randomly: group 1) use of controlled intervaginal drug release devices (CIDR) for 7 days with intramuscular (IM) injection of PGF2α on zero day and IM injection of 500 IU ...

Repair of osteochondral defects created in rabbit femoral trochlea were studied using a water-soluble sulfated p-GlcNAc formulation, (Marine Polymer Technologies, Danvers, MA, USA). After 12 weeks of healing empty defects were compared to defects filled with sulfated p-GlcNAc sponge alone and sulfated p-GlcNAc sponge seeded with autologous chondrocytes. The chondrocyte seeded sponge provided th...

Carbon nanotubes (CNTs) have attractive biochemical properties such as strong cell adhesion and protein absorption, which are very useful for a cell cultivation scaffold. In this study, we prepared a multiwalled carbon nanotube-coated collagen sponge (MWCNT-coated sponge) to improve the surface properties of the collagen sponge, and its cell culturing properties were examined. The suface of the...

در این پژوهش تولید فولاد api 5l-x70 با استفاده از شارژ 100 % آهن اسفنجی مورد بررسی قرار گرفت. در تهیه این فولاد بر خلاف فولادهای api مرسوم از نیوبیوم استفاده نگردید و تنها از عناصر تیتانیم و وانادیم استفاده شد. از طرفی مولیبدن جایگزین مس ونیکل گردید. بدین منظور عملیات فولادسازی در کوره القایی صورت گرفت که شامل مراحل فسفرزدایی، کربن زدایی، اکسیژن زدایی و آلیاژسازی بود. پس از تهیه شمش فولاد مورد ...

The whole metabolism of a sponge holobiont and the respective contributions of prokaryotic and eukaryotic symbionts and their associations with the sponge host remain largely unclear. Meanwhile, compared with shallow water sponges, deep-sea sponges are rarely understood. Here we report the metagenomic exploration of deep-sea sponge Neamphius huxleyi [corrected] . at the whole community level. M...

Symbioses in marine sponges involve diverse consortia of microorganisms that contribute to the health and ecology of their hosts. The microbial communities of 13 taxonomically diverse Great Barrier Reef (GBR) sponge species were assessed by DGGE and 16S rRNA gene sequencing to determine intra and inter species variation in bacterial symbiont composition. Microbial profiling revealed communities...

Cold-water coral reefs are known to locally enhance the diversity of deep-sea fauna as well as of microbes. Sponges are among the most diverse faunal groups in these ecosystems, and many of them host large abundances of microbes in their tissues. In this study, twelve sponge species from three cold-water coral reefs off Norway were investigated for the relationship between sponge phylogenetic c...
