Depression is predicted to become the second highest disease burden by 2020 as well as being a common mental health condition across the globe. Nevertheless, the presentation of depression varies depending on several factors with the patient’s cultural background playing a significant role. Although depression is such a universal condition, the manner of how a patient presents not only affects the clinician’s ability to make a diagnosis, but ultimately affects the wellbeing of the patient. It is therefore paramount that as clinicians we appreciate how culture not only affects the presentation of depression but also how cultural beliefs affect the patient’s acceptance of such a diagnosis.

Broadband(1.6–18 THz) terahertz time-domain spectroscopy(THz-TDS) and time-resolved terahertz spectroscopy(TRTS) were performed on a 54 μm thick chalcogenide glass(As_(30)Se_(30)Te_(40)) sample with a two-color laser-induced air plasma THz system in transmission and reflection modes, respectively. Two absorption bands at 2–3 and 5–8 THz were observed. TRTS reveals an ultrafast relaxation process of the photoinduced carrier response, well described by a rate equation model with a finite concentration of mid-bandgap trap states for self-trapped *** photoinduced conductivity can be well described by the Drude–Smith conductivity model with a carrier scattering time of 12–17 fs, and we observe significant carrier localization effects. A fast refractive index change was observed 100 fs before the conductivity reached its maximum, with 2 orders of magnitude larger amplitude than expected for the optically induced THz Kerr effect, indicating that free carriers are responsible for the transient index change.

Marine derived fungi are considered as a promising source of novel drugs due to their biodiversity and consequent chemo-diversity. Although marine microorganisms especially fungi are not well defined taxonomically, making this a promising frontier for the discovery of new medicines. This study focused on marine derived fungi as a model for bioactive exploration for new entities with anti-inflammatory and antioxidant capacity. Three in-vitro assays were used to investigate the bioactive antioxidant potentiality of fungal extracts. Thiobarbituric acid (TBARS),α,α-Diphenyl-β- picrylhydrazyl (DPPH) and NO assay are based on their total phenolic and flavonoid content of each extract group. Ch. globosum recorded the highest antioxidant activity (92.82%) in TBARS assay, while G. dankaliensis came first by recording 59.28% in DPPH assay in comparison with ascorbic acid (61.83%). In NO inhibition assay, N. oryzae showed 49.3% comparing with ascorbic acid (73.12%). From the preliminary result of our extracts, we can consider the marine derived fungi extracts as promising antioxidant and anti-inflammatory drug candidate.
