Adult Brainstem Gliomas With H3K27M Mutation: Radiology, Pathology, and Prognosis.

Adult brainstem gliomas are difficult to classify based on radiologic and histologic features. A K27M mutation in histone 3 has been described to identify high-grade midline gliomas associated with a particularly unfavorable prognosis. While initially considered a pediatric entity, it is now known that H3K27M-mutant brainstem gliomas occur in all age groups, but they are less well understood in adults.

Effect of Notoginsenoside R1 on autologous adipose graft in rats.

Autologous fat particle transplantation has been widely used by surgeons. The present study evaluated the effect of Notoginsenoside R1 (NR1) treatment on rat autologous fat graft, along with the quality and retention rates. Male Sprague‑Dawley rats (n=60) received fat particle auto‑transplantation from the left abdominal cavity into lateral dorsum.

Enhanced Recovery via Peripheral Nerve Block for Open Hepatectomy.

Background: Enhanced recovery after surgery (ERAS) protocols are now commonplace in many fields of surgery, but only limited data exists for their use in hepatobiliary surgery. We implemented standardized ERAS protocols for all open hepatectomies and replaced thoracic epidurals with a transversus abdominis plane (TAP) block.

Methods: We performed a retrospective cohort study of all patients undergoing open hepatectomy during the 14 months before and 19 months after implementation of an ERAS protocol at our institution (January 2014-September 2016).

Potential effects of low-dose average CT on cardiac implantable electronic devices.

Background: Average CT has been shown to be more accurate than conventional helical CT in quantitation of the PET data. The risk of CT irradiation of a cardiac implantable electronic device (CIED) causing an adverse event is low and is generally outweighed by the clinical benefit of a medically indicated examination. However, irradiation of CIED over one breath cycle in cine CT scan for average CT could impose risks on a patient who is pacing dependent.

Interleukin-13 receptor alpha 2 cooperates with EGFRvIII signaling to promote glioblastoma multiforme.

The interleukin-13 receptor alpha2 (IL-13Rα2) is a cancer-associated receptor overexpressed in human glioblastoma multiforme (GBM). This receptor is undetectable in normal brain which makes it a highly suitable target for diagnostic and therapeutic purposes. However, the pathological role of this receptor in GBM remains to be established.

Role of Sertoli and Leydig Cells in the Regulation of Spermatogonial Stem Cell and Development of Reproductive Disorders in Male C57Bl/6 Mice with Type 1 Diabetes Mellitus.

Course administration streptozotocin to male C57Bl/6 mice induces a complex of symptoms typical of type 1 diabetes mellitus: hyperglycemia and insulin deficiency, focal inflammatory infiltration of the pancreas, destructive changes in the Langerhans islets, damage to the insular apparatus (reduced number of PDX1 cells and insulin expression by the secreting cells). Male reproductive disorder are serious complications of type 1 diabetes mellitus. In "diabetic" mice, interstitial edema with inflammatory infiltration and microvascular disorders in the testicular tissue are observed, the number of endothelial precursors (CD45/CD31) and the total number and percentage of motile spermatozoa decreased, immature spermatogenic epithelium cells are desquamated of into the lumen of the tubules.

Regenerative Potential of Spermatogonial Stem Cells, Endothelial Progenitor Cells, and Epithelial Progenitor Cells of C57Bl/6 Male Mice with Metabolic Disorders.

The properties of spermatogonial stem cells, endothelial progenitor cells, and the epithelial progenitors of C57Bl/6 mice under conditions of metabolic disorders were studied using the model of busulfan-induced suppression of spermatogenesis and in vitro culture technique. Spermatogonial stem cells CD117-CD90 and epithelial progenitors CD45-CD31-Sca-1CD49f derived from the testes of mice with metabolic disturbances demonstrated 17- and 28-fold increase in the respective cell mass and generated cell colonies in vitro. In contrast, spermatogonial stem cells with immune phenotype CD51-CD24CD52 had reduced selfrenewal capacity.

A TNF-JNK-Axl-ERK signaling axis mediates primary resistance to EGFR inhibition in glioblastoma.

Aberrant epidermal growth factor receptor (EGFR) signaling is widespread in cancer, making the EGFR an important target for therapy. EGFR gene amplification and mutation are common in glioblastoma (GBM), but EGFR inhibition has not been effective in treating this tumor. Here we propose that primary resistance to EGFR inhibition in glioma cells results from a rapid compensatory response to EGFR inhibition that mediates cell survival.

Measurement of glycine in healthy and tumorous brain by triple-refocusing MRS at 3 T in vivo.

Glycine (Gly) has been implicated in several neurological disorders, including malignant brain tumors. The precise measurement of Gly is challenging largely as a result of the spectral overlap with myo-inositol (mI). We report a new triple-refocusing sequence for the reliable co-detection of Gly and mI at 3 T and for the evaluation of Gly in healthy and tumorous brain.

Rapid progression to glioblastoma in a subset of IDH-mutated astrocytomas: a genome-wide analysis.

According to the recently updated World Health Organization (WHO) classification (2016), grade II-III astrocytomas are divided into IDH-wildtype and IDH-mutant groups, the latter being significantly less aggressive in terms of both progression-free and total survival. We identified a small cohort of WHO grade II-III astrocytomas that harbored the IDH1 R132H mutation, as confirmed by both immunohistochemistry and molecular sequence analysis, which nonetheless had unexpectedly rapid recurrence and subsequent progression to glioblastoma. Among these four cases, the mean time to recurrence as glioblastoma was only 16 months and the mean total survival among the three patients who have died during the follow-up was only 31 months.
