UNLABELLED BACKGROUND More than 15,000 marine products have been described up to now; Sponges are champion producers, concerning the diversity of products that have been found. Most bioactive compounds from sponges were classified into anti-inflammatory, antitumor, immuno- or neurosurpressive, antiviral, antimalarial, antibiotic, or antifouling. Evaluation of in vitro inhibitory effects of d...

Design of mechanical skeletons of biodegradable synthetic polymers such as poly(L-lactic acid) (PLLA), poly(DL-lactic-co-glycolic acid) (PLGA), and poly(ε-caprolactone) (PCL) is important in the construction of the hybrid scaffolds of biodegradable synthetic polymers and naturally derived polymers such as collagen. In this study, cylinder-shaped PLLA, PLGA, and PCL sponges were prepared by the ...

INTRODUCTION Contaminated sponges might lead to cross-contamination in kitchens since they can transfer microorganisms to surfaces where microorganisms can survive for hours or days and contaminate food. The main objective of this study was to evaluate the transfer and the survival of bacteria from kitchen sponges to surfaces of AISI 316 stainless steel and polyethylene. METHODOLOGY Twenty-fo...

MicroRNA (miRNA) sponges are transcripts with repeated miRNA antisense sequences that can sequester miRNAs from endogenous targets. MiRNA sponges are valuable tools for miRNA loss-of-function studies both in vitro and in vivo. We developed a fast and flexible method to generate miRNA sponges and tested their efficiency in various assays. Using a single directional ligation reaction we generated...

Abstract Wound healing is a complicated system that necessitates an appropriate environment to aid healing. dressing among the most important external variables in wound repair. Technology advancements have led creation of variety dressings treat various types by focusing on four stages Simplicity application, sterility, antibacterial, non‐adherent, gaseous exchange, non‐toxicity, and other qua...

Freshwater sponges (Porifera; Spongillina) include 6 families. Some of them are endemic of ancient lakes Baikal, Tanganyika, Ohrid and Malawi. Others families are cosmopolitan and inhabit inland waters worldwide. Freshwater sponges are important for cleaning of water due their filter activity and are often main part of benthos in the lakes. The taxonomy of freshwater sponges is difficult that c...

In this study presence of various kinds of microorganisms in kitchen sponges were studied. Additionally effects of regular dish washing liquid on Escherichia coli ATCC 8739 and Salmonella typhimurium ATCC 13311 were investigated under laboratory conditions in kitchen sponges with or without food residue. The sponges involved in daily use in households were samples were analysed for the presence...

The presence of bone-marrow-derived stem cells was investigated in a wound-healing model where subcutaneously implanted cellulose sponges were used to induce granulation tissue formation. When cellulose was coated with hydroxyapatite (HA), the sponges attracted circulating haemopoietic and mesenchymal progenitor cells more efficiently than uncoated cellulose. We hypothesized that the giant cell...
