A marine record of Patagonian ice sheet changes over the past 140,000 years.

Terrestrial glacial records from the Patagonian Andes and New Zealand Alps document quasi-synchronous Southern Hemisphere-wide glacier advances during the late Quaternary. However, these records are inherently incomplete. Here, we provide a continuous marine record of western-central Patagonian ice sheet (PIS) extent over a complete glacial-interglacial cycle back into the penultimate glacial (~140 ka).

Asian dust-deposition flux to the subarctic Pacific estimated using single quartz particles.

Iron availability limits marine ecosystem activities in large areas of the ocean. However, the sources and seasonal supply of iron, critically important for controlling surface ocean biogeochemistry and carbon cycling, are poorly understood. The western subarctic Pacific is a high-nutrient and low-chlorophyll region, and despite high concentrations of macronutrients, iron limits phytoplankton production in summer.

Evidence for late-glacial oceanic carbon redistribution and discharge from the Pacific Southern Ocean.

Southern Ocean deep-water circulation plays a vital role in the global carbon cycle. On geological time scales, upwelling along the Chilean margin likely contributed to the deglacial atmospheric carbon dioxide rise, but little quantitative evidence exists of carbon storage. Here, we develop an X-ray Micro-Computer-Tomography method to assess foraminiferal test dissolution as proxy for paleo-carbonate ion concentrations ([CO]).

Possible clinical outcomes using early enteral nutrition in individuals with allogeneic hematopoietic stem cell transplantation: A single-center retrospective study.

Objectives: Intensive nutritional support during allogeneic hematopoietic stem cell transplantation (allo-HSCT) yields improved clinical outcomes. However, the clinical implications of early enteral nutrition (EN) in allo-HSCT remain unclear. This retrospective study was conducted to determine the significance of early EN in individuals who underwent allo-HSCT, and the association between early nutritional intervention and clinical outcomes, including the status of the intestinal microbiome.

[Diffuse large B cell lymphoma with HIV infection presented with disseminated thromboembolism during antiretroviral therapy].

Patients with HIV are at higher risk of developing thrombosis than the general population. We present a rare case of a 57-year-old Japanese man with HIV infection and a malignant lymphoma. He had fever with unknown origin and cervical lymph node swelling 2 months before his hospital visit.

Successful brentuximab vedotin monotherapy against late relapse of classical Hodgkin lymphoma 6 years after first remission.

Brentuximab vedotin monotherapy for late-relapse CHL is a promising therapeutic with sustained CR benefit and avoiding potential toxicities caused by aPBSCT/HDT.

Byproduct-Free Intact Modification of Insulin by Cholesterol End-Modified Poly(ethylene glycol) for in Vivo Protein Delivery.

Insulin is a key peptide hormone used for the treatment of both type I and type II diabetes. To maximize the effect of the treatment of these diseases, the addition of poly(ethylene glycol) (PEGylation) methods for the insulin are widely developed. Here, to make these PEGylation methods the simplest, we report the byproduct-free intact modification of insulin by cholesterol end-modified poly(ethylene glycol) with urethane, propyl, and methoxy groups (that is, Chol-U-Pr-mPEG).

Facile Method of Protein PEGylation by a Mono-Ion Complex.

Diethylaminoethyl end-modified poly(ethylene glycol) (DEAE-PEG) has been synthesized for the noncovalent PEGylation of proteins. The resulting DEAE-PEG and catalase formed an ion complex, that is, a protein mono-ion complex (MIC). The formation of the protein MIC was confirmed by native poly(acrylamide) gel electrophoresis and gel-filtration chromatography.
