Fine root biomass and production in Scots pine stands in relation to stand age [PDF]

open access: yesTree Physiology, 2001
We determined fine root biomass and production of 15-, 35- and 100-year-old Scots pine (Pinus sylvestris L.) stands during three growing seasons. Fine roots were sampled by the soil core method. Mean (+/- SE) annual fine root biomass of Scots pine in the 15-, 35- and 100-year-old stands was 220 +/- 25, 357 +/- 21 and 259 +/- 26 g m(-2), respectively ...

Age-related changes of stability in standing posture.

open access: yesNippon Ronen Igakkai Zasshi. Japanese Journal of Geriatrics, 1986
立位保持能力の加齢的変化について, とくに重心位置を積極的に shift させる能力を中心として検討した. 被験者には22歳から95歳までの健常男子148名を用い, 重心動揺計上に Romberg 姿勢で立たせ次の課題を行なわせた. 1) 開眼および閉眼で安静立位を20秒間保持する. 2) 開眼にて重心位置を随意的に前後方向に shift させた立位姿勢を10秒間保持する. 重心動揺計から出力される足圧中心を重心位置としてとらえ, X-Yレコーダに描記するとともに各時間ごとの累積移行距離をアナライザにより算出した. 踵の最後部から各姿勢における重心動揺軌跡の中心位置までの長さを足長に対する比として算出した.

Nitrogen accumulation, rather than carbon: nitrogen stoichiometric variation, underlies carbon storage during forest succession

open access: yesEnvironmental Research Letters, 2021
Forest ecosystems play an important role in regulating global temperatures through their capability to take up and store CO _2 from the atmosphere, but the magnitude and sustainability of this carbon ( C ) sink is critically dependent on the availability

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
