Heating Efficiency of Different Magnetotactic Bacterial Species: Influence of Magnetosome Morphology and Chain Arrangement.

Magnetotactic bacteria have been proposed as ideal biological nanorobots due to the presence of an intracellular chain of magnetic nanoparticles (MNPs), which allows them to be guided and controlled by external magnetic fields and provides them with theragnostic capabilities intrinsic to magnetic nanoparticles, such as magnetic hyperthermia for cancer treatment. Here, we study three different bacterial species, (MSR-1), (AMB-1), and (MV-1), which synthesize magnetite nanoparticles with different morphologies and chain arrangements. We analyzed the impact of these parameters on the effective magnetic anisotropy, , and the heating capacity or Specific Absorption Rate, SAR, under alternating magnetic fields.

: A rare cause of native valve endocarditis with multifocal emboli to brain and spleen.

is a facultative anaerobic gram-negative rod bacterium, which can acquire pathogenicity through the acquisition of additional genetic material. We present a case of ST1193, an emerging global multidrug-resistant (MDR) high-risk clone, causing native valve endocarditis and septic brain and splenic emboli in a 67-year-old woman.

Collapsing Glomerulopathy Leading To Rapidly Progressive Allograft Failure From Cytomegalovirus and SARS-CoV-2 Infection With Concomitant BK Virus Nephropathy.

We present a challenging clinical case of a 68-year-old female kidney transplant recipient who had a complicated posttransplant course marked by borderline T-cell-mediated rejection and BK virus nephropathy. The treatment for borderline rejection with steroids resulted in overimmunosuppression, and the patient acquired cytomegalovirus infection manifesting as colitis and SARS-CoV-2 infection. This progressed rapidly to collapsing glomerulopathy and allograft failure.

Outcomes of Kidneys Transplanted From Hepatitis C Viremic Donors to Naive Recipients From an Appalachian Rural Kidney Transplant Program.

Objectives: Before the advent of direct-acting antiviral therapy for hepatitis C virus, a large proportion of kidneys from donors with hepatitis C viremia were discarded. Hepatitis C virus is now amenable to effective treatment with excellent seronegativity rates. In this study, we review the outcomes of hepatitis C viremic kidneys transplanted into hepatitis C-naive recipients.

Anaplasmosis-Induced Hemophagocytic Lymphohistiocytosis: A Case Report and Review of the Literature.

Cases of anaplasmosis have increased steadily and are appearing in states where it is less common. While symptoms are usually mild, in rare cases it can cause hemophagocytic lymphohistiocytosis. Here, we present a case of polymerase chain reaction-confirmed with morulae on peripheral blood smear associated with biopsy-proven hemophagocytic lymphohistiocytosis.
