Adaptation of Aglycosylated Monoclonal Antibodies for Improved Production in Komagataella phaffii.

Monoclonal antibodies (mAbs) are a major class of biopharmaceuticals manufactured by well-established processes using Chinese Hamster Ovary (CHO) cells. Next-generation biomanufacturing using alternative hosts like Komagataella phaffii could improve the accessibility of these medicines, address broad societal goals for sustainability, and offer financial advantages for accelerated development of new products. Antibodies produced by K.

Workplace interventions to improve well-being and reduce burnout for nurses, physicians and allied healthcare professionals: a systematic review.

Unlabelled: There is a growing need for interventions to improve well-being in healthcare workers, particularly since the onset of COVID-19.

Objectives: To synthesise evidence since 2015 on the impact of interventions designed to address well-being and burnout in physicians, nurses and allied healthcare professionals.

Design: Systematic literature review.

BIVV001, a new class of factor VIII replacement for hemophilia A that is independent of von Willebrand factor in primates and mice.

Factor VIII (FVIII) replacement products enable comprehensive care in hemophilia A. Treatment goals in severe hemophilia A are expanding beyond low annualized bleed rates to include long-term outcomes associated with high sustained FVIII levels. Endogenous von Willebrand factor (VWF) stabilizes and protects FVIII from degradation and clearance, but it also subjects FVIII to a half-life ceiling of ∼15 to 19 hours.

Novel pancreatic endocrine maturation pathways identified by genomic profiling and causal reasoning.

We have used a previously unavailable model of pancreatic development, derived in vitro from human embryonic stem cells, to capture a time-course of gene, miRNA and histone modification levels in pancreatic endocrine cells. We investigated whether it is possible to better understand, and hence control, the biological pathways leading to pancreatic endocrine formation by analysing this information and combining it with the available scientific literature to generate models using a casual reasoning approach. We show that the embryonic stem cell differentiation protocol is highly reproducible in producing endocrine precursor cells and generates cells that recapitulate many aspects of human embryonic pancreas development, including maturation into functional endocrine cells when transplanted into recipient animals.

Classifying variants of CDKN2A using computational and laboratory studies.

Variants in the CDKN2A tumor suppressor are associated with Familial Melanoma (FM), although for many variants the linkage is weak. The effects of missense variants on protein function and pathogenicity are often unclear. Multiple methods (e.

Infected aortic aneurysms: imaging findings.

Purpose: To determine the imaging characteristics of infected aortic aneurysms.

Materials And Methods: Review of records of patients with surgical and/or microbiologic proof of infected aortic aneurysm obtained over a 25-year period revealed 31 aneurysms in 29 patients. This study included 21 men and eight women (mean age, 70 years).

Transient bone marrow edema in renal transplantation: a distinct post-transplantation syndrome with a characteristic MRI appearance.

We describe four patients who developed severe knee pain within 3 months of renal transplantation. Plain radiographs were normal and inflammatory markers (CRP, ESR) were all within normal ranges. Magnetic resonance imaging (MRI) showed a distinctive pattern in all four cases of bone marrow signal changes, extending from the epiphyseal region into the metaphyseal region in two cases.

Computed tomography fluoroscopy-guided chemical lumbar sympathectomy: simple, safe and effective.

Demographic, clinical and laboratory data were retrospectively collected from records of 146 cases of CT fluoroscopy-guided chemical lumbar sympathectomy for the palliation of inoperable peripheral vascular disease (PVD) between January 1997 and August 1999. Of these, 16% had claudication, 39% had rest pain and 44% had ischaemic ulcers or gangrene. Seventy-three percent of elective cases were outpatients.

CT and MRI appearances of methotrexate leucoencephalopathy.

Methotrexate is a well recognised cause of diffuse symmetrical leucoencephalopathy. The widespread use of the drug in chemotherapeutic regimes necessitates awareness of this complication. A case report and a brief literature review is presented.

False negative biliary scintigraphy in gangrenous cholecystitis.

Gangrenous cholecystitis is a serious complication of acute cholecystitis and is associated with increased morbidity and mortality rates. We report a case in which the diagnosis was suggested by ultrasound, but cholecystectomy delayed due to atypical clinical presentation and a false negative radionuclide biliary scan.

Segmental infarction with graft dysfunction: an emerging syndrome in renal transplantation?

Background: Segmental allograft infarction is a poorly characterized complication following renal transplantation. The present study was undertaken with the goal of defining the incidence, clinical characteristics, pathogenesis, and prognosis of this entity.

Methods: A retrospective study was performed, reviewing the renal scans performed on all renal transplant recipients at our institution, from January 1997 to January 2000.
