Constraining Water Depth Influence on Organic Paleotemperature Proxies Using Sedimentary Archives

open access: yesPaleoceanography and Paleoclimatology, Volume 38, Issue 6, June 2023., 2023
Abstract The TEX86 paleothermometer has been extensively used to reconstruct past sea water temperatures, but it remains unclear which export depths the proxy represents. Here we used a novel approach to better constrain the proxy recording depths by investigating paleotemperature proxies (TEX86, U37K′ ${\mathrm{U}}_{37}^{{\mathrm{K}}^{\prime }}$, RI ...

Mobilization and Export of Particulate and Dissolved Solids and Organic Carbon From Contrasting Mountainous River Watersheds in California and Oregon

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 128, Issue 4, April 2023., 2023
Abstract Concentration‐discharge (C‐Q) relationships of total suspended solids (TSS), total dissolved solids (TDS), particulate organic carbon (POC), and dissolved organic carbon (DOC) were investigated in the tributaries and main‐stems of two mountainous river systems with distinct watershed characteristics (Eel and Umpqua rivers) in Northern ...

Mid‐Term Outcomes of Cemented Stem and Subtrochanteric Shortening Derotational Osteotomy in Total Hip Arthroplasty for Crowe IV Developmental Dysplasia

open access: yesOrthopaedic Surgery, Volume 14, Issue 12, Page 3178-3186, December 2022., 2022
This study aimed to evaluate the outcomes of cemented stem THA with subtrochanteric femoral shortening and transverse derotational osteotomy in patients with Crowe IV DDH. The cemented femoral component showed promising mid‐term follow‐up results. Rather than leading to nonunion, cement leakage may negatively affect bone healing.

Authigenic Clays Versus Carbonate Formation as Products of Marine Silicate Weathering in the Input Sequence to the Sumatra Subduction Zone

open access: yesGeochemistry, Geophysics, Geosystems, Volume 23, Issue 4, April 2022., 2022
Abstract We use geochemical and petrographic data from anoxic sequences of the Nicobar Fan to document extensive marine silicate weathering (MSiW) in the input sediment of the Sumatra subduction zone and the conditions that result in authigenic minerals originating from this reaction: precipitation of authigenic carbonate—which sequesters carbon—and ...

Tephra Deposition and Bonding With Reactive Oxides Enhances Burial of Organic Carbon in the Bering Sea

open access: yesGlobal Biogeochemical Cycles, Volume 35, Issue 11, November 2021., 2021
Abstract Preservation of organic carbon (OC) in marine sediments exerts a major control on the cycling of carbon in the Earth system. In these marine environments, OC preservation may be enhanced by diagenetic reactions in locations where deposition of fragmental volcanic material called tephra occurs.

Ice Age‐Holocene Similarity of Foraminifera‐Bound Nitrogen Isotope Ratios in the Eastern Equatorial Pacific

open access: yesPaleoceanography and Paleoclimatology, Volume 36, Issue 5, May 2021., 2021
Abstract Bulk sediment δ15N records from the eastern tropical Pacific (ETP) extending back to the last ice age most often show low glacial δ15N, then a deglacial δ15N maximum, followed by a gradual decline to a late Holocene δ15N that is typically higher than that of the Last Glacial Maximum (LGM).

Leg Length Balance in Total Hip Arthroplasty for Patients with Unilateral Crowe Type IV Developmental Dysplasia of the Hip

open access: yesOrthopaedic Surgery, Volume 12, Issue 3, Page 749-755, June 2020., 2020
Objective To explore the leg length balance in total hip arthroplasty (THA) with shortening subtrochanteric osteotomy (SSTO) or not for unilateral Crowe type IV developmental dysplasia of the hip (DDH) through the evaluation of postoperative full‐length anteroposterior radiographs.

Comparison of plasma endothelin levels between osteoporotic, osteopenic and normal subjects

open access: yesBMC Musculoskeletal Disorders, 2005
Background It has been demonstrated that endothelins (ET) have significant roles in bone remodeling, metabolism and physiopathology of several bone diseases. We aimed to investigate if there was any difference between the plasma ET levels of osteoporotic
