Annual Sedimentary Record From Lake Donguz-Orun (Central Caucasus) Constrained by High Resolution SR-XRF Analysis and Its Potential for Climate Reconstructions

open access: yesFrontiers in Earth Science, 2018
Bottom sediments of the proglacial Lake Donguz-Orun situated at ∼2500 m a.s.l. in the Elbrus Region (Central Caucasus) reveal regular laminae, characteristic of proglacial varved lakes. This is the first laminated sediment sequence recorded in the region.

Tree-Ring Skeleton Plotting by Computer

open access: yes, 1979
Skeleton plotting is an established manual technique for representing the relative narrowness of tree rings in a single radius. These plots can be used as a visual aid to crossdating.

Sebaceous Carcinoma with Widespread Metastases: A Case Report [PDF]

open access: yesInternational Journal of Scientific Research in Dental and Medical Sciences
Sebaceous carcinoma (SC) is an infrequently encountered skin malignancy noted for its aggressive nature. We report here a 78-year-old male who presented to the Department of Radiation Oncology at RIMS Imphal with a two-month history of painless ulcerated

When is a regular local ring a locality?

open access: yesJournal of Algebra, 1988
The author proves constructively and clearly the following nice fact: A normal local domain \((A,M)\) containing a field \(K\) is essentially of finite type over \(K\) if and only if: (1) the residue field \(A/M\) is a finitely generated extension of \(K\); (3) the quotient field \(L\) of \(A\) is a finitely generated extension of \(K\); and (2) \(\dim(

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Discerning protein pools by selective staining with self‐labeling tags

open access: yesFEBS Letters, EarlyView.
Cell surface proteins have an intra‐ and extracellular pool. Combining genetic fusion to self‐labeling tags that can be addressed with small molecule fluorophores allows separating these pools. We highlight recent developments and techniques for state‐of‐the‐art interrogation of cell surface proteins in the complex tissue setting.
