Screening for BK Virus Infection in Kidney Transplant Recipients at Mohamed V Military Teaching Hospital

Published on: 25th July, 2024

After kidney transplantation, BK polyomavirus reactivation can manifest as nephropathy in 1% to 10% of patients. PCR testing of urine and blood is commonly used to screen for BK polyomavirus nephropathy. The study aims to detect BK virus infection in kidney transplant patients to prevent tubulointerstitial nephropathy and graft loss. This retrospective study includes 26 patients who underwent kidney transplants between January 2019 and December 2023. We diagnosed BK virus infection by performing real-time PCR on blood and urine samples. BKV DNA was detected in 3 patients. Reducing immunosuppressive therapy led to negative PCR results and favorable clinical and biological outcomes in these 3 patients.

Resolution of Chronic Bacterial Prostatitis with Bacteriophage-antibiotic Therapy

Published on: 22nd August, 2024

Chronic bacterial prostatitis is a commonly diagnosed genitourinary infection that presents significant challenges both in diagnosis and treatment. In an upcoming era of antibiotic resistance, and limited therapeutic options it becomes imperative to revise current guidelines and to provide more effective treatment strategies. At the Eliava Phage Therapy Center (Tbilisi, Georgia) we utilize bacteriophage therapy as an alternative approach against chronic bacterial infections. Bacteriophages, viruses that target and lyse specific bacterial cells, can be used as a stand-alone treatment or in conjunction with antibiotics. We present a case report of a patient with prostatitis caused by Escherichia coli infection, who prior to addressing our clinic, has been receiving antibiotic therapy without any positive effect. Our approach of combined use of antibiotics and phages was successful not only in complete clinical improvement but also in total bacterial eradication. This outcome shows the potential of bacteriophage therapy as a valuable adjunct to conventional antibacterials in the management of prostatitis.

Coronaviruses have reached at Pre-elimination Stage with Nine Amino Acid Spike Deletions and Forty-nine Nucleotide 3’-UTR Deletions

Published on: 17th September, 2024

Background: Human 30kb coronaviruses entered through the ACE-2 receptors causing fibrosis of the lungs and causing six million deaths worldwide. Here, we have investigated the mutations, deletions and insertions of the recent JN.1 omicron coronaviruses to demonstrate that coronaviruses have reached the pre-elimination stage. Methods: We multi-aligned the genomes of recent JN.1 variants using NCBI Virus Portal and CLUSTAL-Omega. The spike proteins are multi-aligned using MultAlin software and CLUSTAL-Omega.Results: The 17MPLF spike insertion was confirmed to compensate 24LPP, 31S, 69HV, 145Y, 211N and 483V deletions. The 49nt deletions in the 3’-UTR were found in 4997 JN.1 sequences although 26nt deletion was initiated previously in JN.1 as well as BA.5, BF.7, BQ.1 and XBB.1.5 omicron viruses. We first compare 3-D structures of spike proteins with or without 17MPLF four amino acids insertion and nine amino acids deletions using SWISS MODELLING. The JN.1 viruses caused a more stable trimeric spike involving Thr342, Lys436, Lys440, His441, Ser442, Gly443, Tyr445, Lys479, Ser489, Tyr490, Arg493, Pro494, Thr495, and Gln501 amino acids to interact with ACE-2 receptors. The FLiRT spike mutations were found in most KP.2 variants and other changes occurred at the NH2 terminus.Conclusion: We claimed that pre-death changes were initiated in JN.1 COVID-19 lineages and computer simulation showed that the Howard spike with 17MPLF spike insertion appeared more stable than the Oppentrons-spike without 17MPLF insertion. Surely, conflicts of COVID-19 spike sequences must be resolved.

About Efficiency of High-order Harmonic Generation in Attosecond Physics

Published on: 29th October, 2024

For the first time, the interaction between Hydrogen atom and Free-Electron Lasers (FEL) is simulated. The conversion efficiency of High-order Harmonic Generation (HHG) can be enhanced by utilizing a two-color free electron laser with frequency multiplication. It is found that the conversion efficiency of HHG is improved to the largest extent when fourth-fold frequency multiplication is introduced into two-color FEL. The microscopic mechanism of improving the efficiency of HHG is analyzed and discussed.
