Three new indole alkaloids, ophiorrhines C-D (1-3), together with one known analogue, have been isolated from the plant of Ophiorrhiza cantoniensis Hace. The structures of the new alkaloids with the absolute configurations were elucidated by means of spectroscopic methods, electronic circular dichroism (ECD) and calculated nuclear magnetic resonance (NMR) with DP4+ analysis. Compounds 1 and 2 exhibited certain activity to Con-A induced T cell proliferation, and 1 exhibited good inhibition on LPS-induced B cell proliferation with an IC50 value of 8.7 μM.
Although antimicrobial photodynamic therapy (aPDT) can reduce halitosis immediately after application, it returns after a week. This probably occurs because bacteria residing in the oral cavity may recolonize the dorsum of the tongue.

Verify if modification of oral hygiene behavior associated with aPDT or lingual scraper can reduce halitosis after a 90-day follow-up.

Forty adults with positive halitosis were randomized in G1 (n = 20) -aPDT + oral hygiene behavior (OHB) or G2 (n = 20)- lingual scraper + OHB. G1 group were submitted to 0.005 % methylene blue in the middle and posterior third of the tongue, with pre-irradiation of 1 min. Irradiations were performed with red laser diode (λ =660 nm), 100 mW, 318 J/cm
, 3537 mW/cm
, 9 J per point at 6 points. In the G2 group, the tongue was scraped 10 times on the right side and on the left side with a tongue scraper. All patients were instructed on OHB at baseline, 7 and 90 days (guidance on the use of dental floss and the Bass technique for brushing). Haltongue scraper was not able to reduce halitosis after 90-day follow-up. Despite halitosis remaining higher than 112 ppb in all follow-up periods, the mean values remain 2 or 3 fold smaller than baseline values. Future studies should include other oral hygiene behavior to achieve better results in the treatment of halitosis.

In addition to interacting with carbohydrates, a number of studies have reported the ability of these proteins to modulate the activity of several antibiotics against multidrug-resistant (MDR) strains. In this study, we report the enhanced antibacterial activity of the gentamicin against MDR strains when complexed with a lectin from Canavalia ensiformis seeds (ConA). Hemagglutination activity test and intrinsic fluorescence spectroscopy revealed that the gentamicin can interact with ConA most likely via the carbohydrate recognition domain (CRD) with binding constant (Kb) value estimated of (0.44 ± 0.04) x 104 M-1. Furthermore, the minimum inhibitory concentrations (MIC) obtained for ConA against all strains studied were not clinically relevant (MIC ≥ 1024 μg/mL). However, when ConA was combined with gentamicin, a significant increase in antibiotic activity was observed against Staphylococcus aureus and Escherichia coli. The present study showed that ConA has an affinity for gentamicin and modulates its activity against MDR strains. These results indicate that ConA improves gentamicin performance and is a promising candidate for structure/function analyses.High usage of the synthetic glucocorticoids (GCs) has led to significant presence of this pharmaceutical group in surface waters where it can affect non-target organisms such as fish. Assessment of a fish's metabolism and swimming performance provide reliable sub-lethal measures of effects of GCs on oxygen-requiring processes and ability to swim. In this study, we determined time-dependent (7, 14 and 21 days) effects of the synthetic GC prednisone (1 μg L-1) on sheepshead minnow (SHM) (Cyprinodon variegatus). Standard (SMR), routine (RMR) and maximum (MMR) metabolic rate, metabolic scope (MS), excess post-exercise oxygen consumption (EPOC), cost of transport (COT) and critical swimming speed (Ucrit) were determined. Twenty-one days exposure to prednisone resulted in significantly higher SMR, RMR, MMR, MS, EPOC and COT compared with 7d and 14d prednisone fish. However, Ucrit was not significantly different between prednisone and solvent control exposed fish (within 7d, 14d, 21d groups). SMR, RMR and MMR were lower in the 7d and 14d prednisone exposed fish compared with their solvent control groups. In contrast, SMR, RMR and MMR were all significantly higher in the 21d prednisone exposed fish compared with solvent control. EPOC was significantly higher in 14d prednisone exposed fish and trending higher in 21d and 7d prednisone exposed fish compared with their solvent controls. EPOC was significantly higher in 21d compared with 7d prednisone exposed fish. A significantly higher COT was seen in the 21d compared with 7d and 14d prednisone fish. Collectively, this study showed time-dependent effects of prednisone on SHM metabolism and swimming performance.
Due to lack of approved drugs and vaccines, the medical world has resorted to older drugs, produced for viral infections and other diseases, as a remedy to combat COVID-19. The accumulating evidence from in vitro and in vivo studies for SARS-CoV and MERS-CoV have demonstrated that several polyphenols found in plants and zinc- polyphenol clusters have been in use as herbal medicines have antiviral activities against viruses with various mechanisms.

Curcumin, zinc and zinc-ionophores have been considered as nutraceuticals and nutrients showing great antiviral activities with their medicinal like activities.

In this work, we discussed the potential prophylactic and/or therapeutic effects of curcumin, zinc and zinc-ionophores in treatment of viral infections including COVID-19.

Curcuminoids and Zinc classified as nutraceuticals under GRAS (Generally Recognized As Safe) by FDA can provide complementary treatment for COVID 19 patients with their immunity-boosting and antiviral properties.
