Abstract
Mucormycosis, a rare but deadly fungal infection, was an epidemic during the COVID-19 pandemic. The rise in cases (COVID-19-associated mucormycosis, CAM) is attributed to excessive steroid and antibiotic use, poor hospital hygiene, and crowded settings. Major contributing factors include diabetes and weakened immune systems. The main manifesting forms of CAM─cutaneous, pulmonary, and the deadliest, rhinocerebral─and disseminated infections elevated mortality rates to 85%. Recent focus lies on small-molecule inhibitors due to their advantages over standard treatments like surgery and liposomal amphotericin B (which carry several long-term adverse effects), offering potential central nervous system penetration, diverse targets, and simpler dosing owing to their small size, rendering the ability to traverse the blood-brain barrier via passive diffusion facilitated by the phospholipid membrane. Adaptation and versatility in mucormycosis are facilitated by a multitude of virulence factors, enabling the pathogen to dynamically respond to various environmental stressors. A comprehensive understanding of these virulence mechanisms is imperative for devising effective therapeutic interventions against this highly opportunistic pathogen that thrives in immunocompromised individuals through its angio-invasive nature. Hence, this Review delineates the principal virulence factors of mucormycosis, the mechanisms it employs to persist in challenging host environments, and the current progress in developing small-molecule inhibitors against them.

Effect of thymoquinone on transient receptor potential melastatin (TRPM) channels in rats with liver ischemia reperfusion model in rats. IRANIAN JOURNAL OF BASIC MEDICAL SCIENCES 2024; 27:319-325. [PMID: 38333755 PMCID: PMC10849204 DOI: 10.22038/ijbms.2023.71990.15647] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Figures] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Accepted: 08/15/2023] [Indexed: 02/10/2024]
Abstract
Objectives We aimed to investigate the levels of transient receptor potential melastatin (TRPM) gene expression, and the antioxidant and histopathologic effect of thymoquinone (Tmq) in the hepatic I/R rat model. Materials and Methods Fifty Wistar rats were divided into 5 groups. Group 1: Control; Group 2: Sham; Group 3: Hepatic I/R (45 min/45 min); Group 4: Tmq (50 mg/kg); Group 5: Tmq+I/R (ten days before I/R at the dose of 50 mg/kg of Tmq). The hepatic I/R (45min/45min) model was performed at the portal vein and the hepatic artery with atraumatic vascular clamp in the ischemia groups. The liver tissues and blood samples that were taken at the end of the study were evaluated for histopathologic and biochemical analysis. Besides TRPM gene expression levels were determined in liver tissues. It was seen that cellular swelling, congestion, PNL, and apoptosis parameters statistically decreased in Tmq and Tmq+I/R groups in comparison with the I/R group in histopathological evaluation. Results It was observed that biochemical parameters, AST, ALT, GGT, LDH, creatinine, and urea levels significantly increased in the I/R group as compared with, sham, Tmq, and Tmq+I/R groups. It was found that TRPM2,6,7,8 gene expression decreased significantly in Tmq+I/R groups as compared to the I/R group. Conclusion We showed that thymoquinone can inhibit the entry of Ca+2 into the cell by decreasing TRPM2,6,7,8 gene expression. Based on our findings, we think that Tmq application in the treatment of liver diseases due to I/R damage may be important in terms of both ischemia and apoptosis and can also be used in the treatment of liver-related diseases.

Preclinical evaluation of antimalarial activity of CPF-1 formulation as an alternative choice for the treatment of malaria. BMC Complement Med Ther 2023; 23:144. [PMID: 37143036 PMCID: PMC10158254 DOI: 10.1186/s12906-023-03973-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2023] [Accepted: 04/25/2023] [Indexed: 05/06/2023] Open
Abstract
BACKGROUND Kheaw Hom remedy is a traditional Thai medicine used to treat fever. Some plants used in the Kheaw Hom remedy show promising in vitro antimalarial activity. This study prepared novel formulations of plants from the Kheaw Hom remedy and evaluated their antimalarial and toxicological activities. METHODS Seven new formulations were prepared by combining at least three herbs of six selected plants from the Kheaw Hom remedy, namely Mammea siamensis Kosterm., Mesua ferrea L., Dracaena loureiroi Gagnep., Pogostemon cablin (Blanco) Benth., Kaempferia galanga L, and Eupatorium stoechadosmum Hance. In vitro antimalarial activities of each formulation's aqueous and ethanolic extracts were evaluated using the parasite lactate dehydrogenase (pLDH) assay. Cytotoxicity in Vero and HepG2 cells was assessed using the MTT assay. An extract with good antimalarial potency and selectivity index (SI) was selected for in vivo antimalarial activity using Peter's 4-day suppressive test and acute oral toxicity test in mice. In addition, bioactive compounds were identified using Gas chromatography-mass spectrometry (GC-MS) analysis. RESULTS Among the seven new formulations, ethanolic extracts of CPF-1 (Formulation 1) showed the highest activity with an IC50 value of 1.32 ± 0.66 µg/ml, followed by ethanolic extracts of Formulation 4 and Formulation 6 with an IC50 value of 1.52 ± 0.28 µg/ml and 2.48 ± 0.34 µg/ml, respectively. The highest SI values were obtained for the ethanolic extract of CPF-1 that was selected to confirm its in vivo antimalarial activity and toxicity. The results demonstrated a significant dose-dependent reduction in parasitemia. Maximum suppressive effect of the extract (72.01%) was observed at the highest dose administered (600 mg/kg). No significant toxicity was observed after the administration of 2000 mg/kg. Using GC-MS analysis, the most abundant compound in the ethanolic extract of CPF-1 was ethyl p-methoxycinnamate (14.32%), followed by 2-propenoic acid, 3-phenyl-, ethyl ester, (E)- (2.50%), and pentadecane (1.85%). CONCLUSION The ethanolic extract of CPF-1 showed promising in vitro and in vivo antimalarial efficacy, with no toxic effects at a dose of 2000 mg/kg, suggesting that the ethanolic extract of CPF-1 may serves as a new herbal formulation for the treatment of malaria. Additional research is required for safety and clinical pharmacology studies.

Developing novel liquid biopsy by selective capture of viral RNA on magnetic beads to detect COVID-19. IRANIAN JOURNAL OF BASIC MEDICAL SCIENCES 2022; 25:762-766. [PMID: 35949306 PMCID: PMC9320198 DOI: 10.22038/ijbms.2022.65260.14379] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/30/2022] [Accepted: 06/08/2022] [Indexed: 11/07/2022]
Abstract
Objectives Early, specific, and sensitive detection methods of COVID-19 are essential for force stopping its worldwide infection. Although CT images of the lung and/or viral RNA extraction followed by real-time reverse-transcriptase-polymerase chain reaction (rRT-PCR) are widely used; they have some limitations. Here, we developed a highly sensitive magnetic bead-based viral RNA extraction assay followed by rRT-PCR. Materials and Methods Case group included oropharyngeal/nasopharyngeal and blood samples from 30 patients diagnosed positive by PCR test for COVID-19 and control group included 30 same samples from COVID-19 negative PCR test individuals. RNA was extracted, using viral RNA extraction kit as well as using our hand-made capture bead-based technique. A one-step cDNA synthesis and Real Time PCR was conducted. A two-step comparison of the different viral RNA extraction methods for oropharyngeal/nasopharyngeal and blood samples was performed. Student t-test was applied with a P<0.05 considered statistically significant. Results In the case group, all 30 mucosal samples extracted either with viral RNA extraction kit or with beads-based assay were COVID-19 positive although in the latter category, Cqs were much lower. Although 43% of plasma samples extracted by bead-based method were found to be positive but no plasma samples extracted with column-based kit were detected positive by Real Time PCR. Conclusion Bead-based RNA extraction method can reduce RNA loss by its single-tube performance and enhance the test sensitivity. It is also more sensitive to lower viral loads as shown in the detection of blood samples and the lower Cqs of mucosal samples.
