Graphene nanoshells (MGNS) were prepared from cellulose, a sustainable biopolymer. Different sizes/morphologies were obtained by simply changing the metal catalyst salt in the synthesis. The MGNS were shown to reversibly cycle Li-ions by an intercalation mechanism similar to graphite.

However, the macropores of these cathodes require a relatively large mass of electrolyte to fill, resulting in lower true gravimetric and volumetric capacities. Here we report a simple method to incorporate a mesoporous material, carbon nanochains (CNCs), into the macropores of MWCNTs, resulting in composite cathodes that fully utilize their pore structure to store LiO product.

There are very limited data describing the natural history of patients with extra-visceral retroperitoneal PEComas of the retroperitoneum. The aim of this study is to describe the clinical features, treatment patterns, outcomes, and diagnostic challenges of primary extra-visceral retroperitoneal or abdominopelvic PEComa over the past decade.

However, exceedingly few studies have documented actual water quality impacts of such misapplications. Here, we explore the short- and longer-term effects of an operational misapplication of PHOS-CHEK LC95A into a Rocky Mountain stream on (a) water quality, (b) streambed storage and release potential of soluble reactive phosphorus (SRP), (c) its downstream transport, and (d) effects on periphyton productivity.

Epithelioid hemangioendothelioma (EHE) is an ultra-rare sarcoma with a paucity of data on best practices for management. Pathogenic translocations involving the YAP or TAZ genes lead to constitutive activation of TEAD and TEAD-associated pathways. As our understanding of the molecular drivers of EHE has advanced, investigational treatment strategies have shifted away from cytotoxic chemotherapy toward more targeted approaches.

Purpose: Chondrosarcomas are rare cancers of cartilage with limited systemic therapy options. To identify potential therapeutic targets, this study investigated the molecular and immune landscape of three chondrosarcoma subtypes using a large database of clinical-grade sequencing results.
Methods: Deidentified records from patients with a histologic diagnosis of conventional, dedifferentiated, or mesenchymal chondrosarcoma sequenced by the Tempus xT DNA assay were included.

The conversion of biochar, the low value byproduct of pyrolysis bio-oil production from biomass multi-walled carbon nanotubes (MWCNTs) and carbon nanochains (CNCs), is reported. It is shown that biomass can be converted to long (>30 µm) carbon nanotubes with an anomalously deep (>280 nm) stacked-cup structure. A mechanism of the transformation that is consistent with previously reported graphitization of biochar, a "non-graphitizable" carbon, is proposed, suggesting the molten metal catalyst is absorbed into the biochar by capillary action, forming graphene walls as it percolates through pore structure.

However, their practical performance is far less, in part due to their low true capacities, that is, capacity including the mass of the typically porous active material, electrolyte in the pores and the LiO discharge product. This is further limited by the particulate nature of the product, yielding a theoretical maximum packing density of 74%, impacting both gravimetric and volumetric capacities.

Extracting lithium from alternative aqueous sources such as geothermal brines plays an important role in meeting this demand. Electrochemical intercalation emerges as a promising Li extraction technology due to its ability to offer high selectivity for Li and its avoidance of harsh chemical regenerants.

Purpose: FHD-609, a potent, selective, heterobifunctional degrader of bromodomain-containing protein 9 (BRD9), was evaluated for treating patients with advanced synovial sarcoma or SMARCB1-deficient tumors.
Patients And Methods: In this multinational, open-label, phase I study (NCT04965753), patients received FHD-609 intravenously at escalating doses either twice weekly (5-80 mg; n = 40) or once weekly (40-120 mg; n = 15).
Results: Fifty-five patients received FHD-609 for a median of 43 days.

Although rare, PD-1 blockade in patients with cancer can lead to exacerbation of infection-associated pathology. Here, we detail the case of a 38-year-old man who was enrolled in a clinical trial for assessment of the safety and activity of anti-PD-1 therapy for Kaposi sarcoma in people with HIV well-controlled on antiretroviral therapy.

A subset of IMTs have fusions involving ALK or ROS1. The role of next-generation sequencing (NGS) for classification of unselected sarcomas remains controversial.

Importance: Angiosarcoma is an aggressive vascular malignant neoplasm presenting either as a primary or secondary cancer, often arising after radiotherapy or in the context of preexisting lymphedema. Comprehensive data describing its incidence and presentation patterns are needed.
Objective: To describe the incidence, presenting characteristics, and change over time of angiosarcoma in the US.
Importance: Gastrointestinal stromal tumor (GIST) is a rare cancer treated with the tyrosine kinase inhibitors imatinib mesylate or sunitinib malate. In general, in low- and middle-income countries (LMICs), access to these treatments is limited.

Malignant bone tumors are commonly classified as pediatric or adolescent malignancies, and clinical trials for these diseases have generally focused on these populations. Of primary bone cancers, osteosarcoma is among the most common. Osteosarcoma has a bimodal age distribution, with the first peak occurring in patients from 10 to 14 years old, and the second peak occurring in patients older than 65, with about 25% of cases occurring in adults between 20 and 59 years old.

Intratumoral (IT) injection of the toll-like receptor 4 (TLR4) agonist glycopyranosyl lipid A in stable-emulsion formulation (GLA-SE) has been studied as immunotherapy in other contexts.
Objective: To evaluate the safety, efficacy, and immunomodulatory effects of IT GLA-SE with concurrent radiotherapy in patients with metastatic STS with injectable lesions.
Objectives: Angiosarcoma is a rare complication of breast-conserving therapy. This study evaluated the change in incidence between 1992 and 2016 of secondary breast angiosarcoma (SBA) in patients with a history of breast cancer and the impact of management strategies for the original breast carcinoma on angiosarcoma treatment.
Methods: Breast cancer and angiosarcoma cases were abstracted from the Surveillance, Epidemiology, and End Result (SEER) database.
Background: Malignant hemangioendothelioma is an endothelial cancer with heterogeneous clinical behavior that can range from indolent to aggressive, of which the majority are epithelioid (EHE). Its incidence and demographics have not been previously well defined in a large cohort.
Methods: This retrospective analysis used the US Cancer Statistics National Program of Cancer Registries - Surveillance Epidemiology End Results (SEER) combined database to identify patients in the US newly diagnosed with hemangioendothelioma between the years of 2001 and 2017 (n = 1986).
Background: Dedifferentiated chondrosarcoma (DDCS) is a rare subset of chondrosarcoma. It is an aggressive neoplasm characterized by a high rate of recurrent and metastatic disease with overall poor outcomes. Systemic therapy is often used to treat DDCS; however, the optimal regimen and timing are not well defined, with current guidelines recommending following osteosarcoma protocols.
