This paper presents a study on developing a new exoskeleton for ankle joint rehabilitation with three degrees of freedom (3 DOFs). The primary attention is paid to the process of designing and modelling the device aimed at restoring the lost functions of joint mobility. The authors conducted a complex analysis of the functional requirements of the exoskeleton based on research into the potential user's needs, which allowed for the development of a conceptual model of the proposed device.

Microalgae are powerful source for nutritionally valuable components as proteins, carbohydrates and especially unsaturated fatty acids. Microalgae may be employed in pharmaceutical, food, cosmetic, health industries, and biofuels. In this study for looking at high-level unsaturated fatty acids species, from 31 strains, by comparing growth curves, the best strain with a high growth rate and lipid content was selected by red Nile staining.

In this paper, we report a new method to grow graphene monolayers directly on a quartz substrate using chemical vapor deposition (CVD), without using any catalyst. For this purpose, ethanol as the precursor and a quartz substrate were used for growth, which controlled the growth process and the formation of an ultrathin layer of graphene. In this project, with use of plasma-enhanced chemical vapor deposition (PECVD), the substrate was cleaned by applying the cold plasma with the aim of improving the quality of the graphene monolayer grown.

One of the major environmental problems nowadays is petroleum hydrocarbons contamination. Bioremediation is widely used for cleaning ecosystems contaminated with petroleum hydrocarbons. This study was carried out to investigate the response of five microalgae strains isolated from different regions in Iran for 1% n-dodecane (DOD) degradation.

Article Synopsis
  • The study builds on previous research about Nostoc entophytum ISC32's response to cadmium-induced stress at cellular and molecular levels, focusing on changes in antioxidant enzyme activity and lipid peroxidation.
  • Exposure to cadmium at lower concentrations (2 and 5 mg/L) significantly increased catalase and peroxidase activity, but higher concentrations (10 and 20 mg/L) did not yield substantial changes, and high cadmium levels caused notable lipid peroxidation after prolonged exposure.
  • Structural analysis revealed significant alterations in the cyanobacterial cells, such as cell shrinkage and detachment of the mucilage layer due to cadmium toxicity, especially at concentrations above the minimum inhibitory concentration (30 mg/L), indicating a defense response

Among nine cyanobacterial strains isolated from oil-contaminated regions in southern Iran, an isolate with maximum cadmium uptake capacity was selected and identified on the basis of analysis of morphological criteria and 16S rRNA gene sequence similarity as Nostoc entophytum (with 99% similarity). The isolate was tentatively designated N. entophytum ISC32.

Article Synopsis
  • A study analyzed the essential oils from three types of sage plants (Salvia multicaulis, S. sclarea, and S. verticillata) collected at peak bloom using hydrodistillation and advanced gas chromatography techniques.
  • The essential oils were tested for antimicrobial effects against various bacteria and fungi, showing moderate to high antibacterial activity against most bacteria except for Pseudomonas aeruginosa, which was resistant.
  • Antifungal activity was minimal, with only the oil from S. multicaulis exhibiting slight effectiveness against two yeast strains (Candida albicans and Saccharomyces cerevisiae).

A gene encoding the proteinaceous alpha-amylase inhibitor Paim was cloned and sequenced. Southern analysis and the amino acid sequence deduced from the cloned gene indicated that Paim isoforms were encoded in the same gene. When the gene was expressed in Escherichia coli and Streptomyces lividans, recombinant Paim inhibitors were produced in the periplasmic space and in the culture supernatant, respectively.
