Primary diffuse leptomeningeal glioblastoma: a case report and literature review.

Purpose: Glioblastoma (GBM) that presents as leptomeningeal disease (LMD) is extremely rare and fatal. Limited data are available regarding incidence, clinical presentation, and management. Prognosis is poor and no treatment is known to improve survival.

Using native and synthetic genes to disrupt inositol pyrophosphates and phosphate accumulation in plants.

Inositol pyrophosphates are eukaryotic signaling molecules that have been recently identified as key regulators of plant phosphate sensing and homeostasis. Given the importance of phosphate to current and future agronomic practices, we sought to design plants, which could be used to sequester phosphate, as a step in a phytoremediation strategy. To achieve this, we expressed diadenosine and diphosphoinositol polyphosphate phosphohydrolase (DDP1), a yeast (Saccharomyces cerevisiae) enzyme demonstrated to hydrolyze inositol pyrophosphates, in Arabidopsis thaliana and pennycress (Thlaspi arvense), a spring annual cover crop with emerging importance as a biofuel crop.

Role of scaffold proteins in the heterogeneity of glioblastoma.

Glioblastoma (GB) is a highly heterogeneous type of incurable brain cancer with a low survival rate. Intensive ongoing research has identified several potential targets; however, GB is marred by the activation of multiple pathways, and thus common targets are highly sought. The signal regulatory scaffold IQGAP1 is an oncoprotein implicated in GB.

Minimally invasive versus open esophagectomy: Comparing the combined effects of smoking burden and operative approach on outcomes in esophagectomy.

Objective: To evaluate the interaction between smoking status and operative approach following esophagectomy on perioperative outcomes.

Methods: Patients undergoing esophagectomy for esophageal cancer between January 1, 2009, and December 31, 2022, were identified from the STS-GTSD database and divided into 6 groups based on smoking status-never (NS), former (FS), or current (CS)-and surgical approach-minimally invasive (MIE) or open (OpenE). Primary outcomes were respiratory complications, operative mortality, major morbidity, and composite major morbidity and mortality.

The Relationship Between Nodal Metastases and Primary Location in Stage I Non-Small Cell Lung Cancer.

Introduction: This study examines the relationship between location of the primary tumor and specific nodal metastases in clinical stage 1 non-small cell lung cancer (NSCLC) patients undergoing lobectomy.

Methods: We retrospectively analyzed all lobectomies performed at a single institution, between January 2005 and December 2019, for clinical stage I NSCLC patients. Patients selected for this study were clinically node negative (cN0) by positron emission tomography-computed tomography scan and selectively by endobronchial ultrasound or mediastinoscopy.

Longitudinal Follow-up of Medicare Patients After Esophageal Cancer Resection in the STS Database.

Background: Understanding characteristics associated with survival after esophagectomy for cancer is critical to preoperative risk stratification. This study sought to define predictors for long-term survival after esophagectomy for cancer in Medicare patients.

Methods: The Society of Thoracic Surgeons General Thoracic Surgery Database was queried for patients aged ≥65 years who underwent esophagectomy for cancer between 2012 and 2020 and linked to Centers for Medicare and Medicaid Services (CMS) data using a deterministic matching algorithm.

Crystal structure of 4-bromo-5,7-dimeth-oxy-2,3-di-hydro-1-inden-1-one.

In the title mol-ecule, CHBrO, the di-hydro-indene moiety is essentially planar but with a slight twist in the saturated portion of the five-membered ring. The meth-oxy groups lie close to the above plane. In the crystal, π-stacking inter-actions between six-membered rings form stacks of mol-ecules extending along the axis direction, which are linked by weak C-H⋯O and C-H⋯Br hydrogen bonds.

Adult caudal fin shape is imprinted in the embryonic fin fold.

Appendage shape is formed during development (and re-formed during regeneration) according to spatial and temporal cues that orchestrate local cellular morphogenesis. The caudal fin is the primary appendage used for propulsion in most fish species, and exhibits a range of distinct morphologies adapted for different swimming strategies, however the molecular mechanisms responsible for generating these diverse shapes remain mostly unknown. In zebrafish, caudal fins display a forked shape, with longer supportive bony rays at the periphery and shortest rays at the center.

Ethyl 2-[(2-oxo-2-chromen-6-yl)-oxy]acetate.

Ethyl 2-[(2-oxo-2-chromen-6-yl)-oxy]acetate, CHO, a member of the pharmacologically important class of coumarins, crystallizes in the monoclinic 2/ space group in the form of sheets, within which mol-ecules are related by inversion centers and 2 axes. Multiple C-H⋯O weak hydrogen-bonding inter-actions reinforce this pattern. The planes of these sheets are oriented in the approximate direction of the face diagonal.

Bis[tris-(diiso-butyl-dithio-carbamato)-μ-sulfido-tri-μ-di-sulfido-trimolybdenum(IV)] sulfide tetra-hydro-furan monosolvate.

The title compound, [Mo(CHNS)(S)S]S, crystallizes on a general position in the monoclinic space group 2/ (No. 14). The cationic [MoS(SCNBu)] fragments are joined by a mono-sulfide dianion that forms close S⋯S contacts to each of the di-sulfide ligands on the side of the Mo plane opposite the μ ligand.

Inflammatory breast cancer (IBC) advocacy-Past, present and future!

Patient advocates, referring to those individuals that have been diagnosed with the disease for which they advocate, are essential stake holders in healthcare. For those facing the stages of being diagnosed with Inflammatory Breast Cancer (IBC), the "call to advocate" is an immediate response to being diagnosed with a rare and aggressive disease that progresses rapidly, often in a matter of weeks or months. There is a great stigma and bias in the medical community that has inhibited the education and study of IBC.

Nonlinear social evolution and the emergence of collective action.

Organisms from microbes to humans engage in a variety of social behaviors, which affect fitness in complex, often nonlinear ways. The question of how these behaviors evolve has consequences ranging from antibiotic resistance to human origins. However, evolution with nonlinear social interactions is challenging to model mathematically, especially in combination with spatial, group, and/or kin assortment.

The single-atom R1: a new optimization method to solve crystal structures.

A crystal structure with N atoms in its unit cell can be solved starting from a model with atoms 1 to j - 1 being located. To locate the next atom j, the method uses a modified definition of the traditional R1 factor where its dependencies on the locations of atoms j + 1 to N are removed. This modified R1 is called the single-atom R1 (sR1), because the locations of atoms 1 to j - 1 in sR1 are the known parameters, and only the location of atom j is unknown.

Vein-first artery-first robotic lobectomy outcomes in non-small cell lung cancer.

Background: Data remains limited as to whether the order of pulmonary vessel division during performance of a lobectomy for non-small cell lung cancer (NSCLC) affects survival outcomes. Some authors have suggested that ligation of the pulmonary veins should be conducted first in order to minimize the spread of tumor cells secondary to manipulation of the lung. This study examines whether there is a difference in outcomes between patients who undergo robotic lobectomies for NSCLC using a vein-first (V-first) artery-first (A-first) technique.

Mechanism of Ventricular Tachycardia Occurring in Chronic Myocardial Infarction Scar.

Cardiac arrest is the leading cause of death in the more economically developed countries. Ventricular tachycardia associated with myocardial infarct is a prominent cause of cardiac arrest. Ventricular arrhythmias occur in 3 phases of infarction: during the ischemic event, during the healing phase, and after the scar matures.

Phase I study targeting newly diagnosed grade 4 astrocytoma with bispecific antibody armed T cells (EGFR BATs) in combination with radiation and temozolomide.

Purpose: The purpose of this study was to determine the safety, feasibility, and immunologic responses of treating grade 4 astrocytomas with multiple infusions of anti-CD3 x anti-EGFR bispecific antibody (EGFRBi) armed T cells (EGFR BATs) in combination with radiation and chemotherapy.

Methods: This phase I study used a 3 + 3 dose escalation design to test the safety and feasibility of intravenously infused EGFR BATs in combination with radiation and temozolomide (TMZ) in patients with newly diagnosed grade 4 astrocytomas (AG4). After finding the feasible dose, an expansion cohort with unmethylated O-methylguanine-DNA methyltransferase (MGMT) tumors received weekly EGFR BATs without TMZ.
