Hybrid nerve sheath tumor of the spinal canal and neurofibromatosis-2, where the twain shall meet-a case report and review of literature.

Background: A hybrid nerve sheath tumor is a biphasic, benign neoplasm of peripheral nerve sheaths, consisting of combinations of neurofibroma, schwannoma, or perineurioma. These tumors were recognized only recently, in 2013; they commonly occur sporadically but rarely with syndromic associations, such as neurofibromatosis syndrome, Carney complex, and schwannomatosis. With an occurrence of 1 in every 33,000 individuals, neurofibromatosis type 2 is a rare autosomal dominant condition characterized by bilateral vestibular schwannomas.

Multiplexed epigenetic memory editing using CRISPRoff sensitizes glioblastoma to chemotherapy.

Background: Glioblastoma (GBM) carries a poor prognosis, and new therapeutic strategies are necessary to improve outcomes for patients with this disease. Alkylating chemotherapies including temozolomide (TMZ) and lomustine (CCNU) are critical for treating GBM, but resistance mechanisms, including hypomethylation of O6-methylguanine-DNA methyltransferase (MGMT) promoter, undermine treatment. CRISPRoff is a programmable epigenetic memory editor that can induce stable and heritable gene silencing after transient delivery, and we hypothesize that CRISPRoff could potentiate the activity of TMZ and CCNU through long term suppression of target genes.

Adenovirus: a possible trigger for IgA vasculitis in children.

IgA vasculitis (IgAV), also called Henoch-Schönlein purpura (HSP), is an immune complex vasculitis characterised by IgA1-dominant immune deposits affecting small vessels (predominantly capillaries, venules or arterioles). It often involves the skin and gastrointestinal tract, frequently causes arthritis and rarely causes vasculitis in the kidney indistinguishable from IgA nephropathy. It usually presents as a purpuric non-blanching rash mostly on the lower limbs, although it may extend to the upper limbs and the trunk, and more rarely to the face.

A paradigm shift: analytical ultracentrifugation as a multi-attribute platform method in targeted protein degradation.

Targeted protein degradation (TPD) has garnered appreciable interest in drug discovery due to its unique mechanism of action - degradation of a target in an event-driven manner, instead of traditional occupancy-driven inhibitor-based therapies. This is achieved by employing mono- or hetero-bifunctional small molecules known as degraders to induce the proximity of two proteins: a target protein and an E3 ubiquitin ligase, ultimately resulting in clearance of the target protein by the cell's inherent degradation machinery. A critical step in this pathway is ternary complex formation (TCF) between the ligase, degrader molecule, and the target protein.

Insights into the structural and biophysical mechanisms of benzamidine-driven inhibition of human lysozyme aggregation.

Amyloid fibril formation is a hallmark of several protein misfolding diseases, including systemic hereditary amyloidosis (SHA), in which lysozyme aggregates into plaques, causing inflammation to various tissues. SHA is a rare disease with no current drug treatment options. In our efforts to identify potential therapeutics for SHA, we investigated the inhibitory effects of benzamidine (BEN) on the human lysozyme fibrillation (HLF).

De novo giant prostatic adenocarcinoma: A rare case report.

Giant prostatic adenocarcinoma is an extremely rare scenario with only two cases reported till date. To the best of our knowledge, our patient, a 76-year-old gentleman adds to the literature as the third case of giant prostatic adenocarcinoma and the second largest in volume. In spite of high pretreatment serum prostate-specific antigen value, he had a nonmetastatic disease that was treated successfully with radical intent, and it is the highlight of this case.

Association of lower tumor mutation burden with rapid local progression in patients with brain metastases.

Objective: Tumor mutational burden (TMB) has been proposed as a prognostic biomarker in patients with metastatic cancer, as well as in patients who receive immune checkpoint inhibitor (ICI) therapy. However, the role of TMB as a biomarker for progression after resection of brain metastases, as well as perioperative ICI treatment response, is less defined. This study examined the impact of TMB on local CNS progression events in patients who underwent resection of a brain metastasis, as well as in those who received postoperative ICI treatment.

Delayed Corticosteroid Treatment for Patients Requiring Hospitalization for Acute Inflammatory Bowel Disease Exacerbations Increases Length of Stay and Risk for Surgery in Crohn's Disease.

Background: While corticosteroids are not recommended for maintenance of remission in inflammatory bowel disease (IBD), they are quite effective for the induction of remission for both Crohn's disease (CD) and ulcerative colitis (UC). We aimed to evaluate if a delay in starting corticosteroids after presentation to the hospital for an acute IBD exacerbation increased the likelihood of poor outcomes.

Methods: Retrospective cohort study of IBD-related hospitalizations from 7 area hospitals in Austin, Texas between 2015 and 2020.
