Spatial patterns in untouched beech (Fagus orientalis Lipsky) stands over forest development stages in Kelardasht region of Iran [PDF]

تحقیقات جنگل و صنوبر ایران, 2010
Determination of trees spatial patterns in each development stage illustrates the dynamic of stands during the time and can provide valuable information on the underlying processes, particularly in case of uneven-aged forests. For this purpose, three one-

Elevated CO₂ does not increase eucalypt forest productivity on a low-phosphorus soil [PDF]

, 2017
Rising atmospheric CO2 stimulates photosynthesis and productivity of forests, offsetting CO2 emissions. Elevated CO2 experiments in temperate planted forests yielded ~23% increases in productivity over the initial years.

Age‐Related Characteristics of SYT1‐Associated Neurodevelopmental Disorder

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives We describe the clinical manifestations and developmental abilities of individuals with SYT1‐associated neurodevelopmental disorder (Baker‐Gordon syndrome) from infancy to adulthood. We further describe the neuroradiological and electrophysiological characteristics of the condition at different ages, and explore the associations ...

Ongoing study on the integration of biodiversity concerns in management of forest concessions in Central Africa [PDF]

, 2008
Central Africa is home to the world's second largest contiguous tropical rainforest, after Amazon. Depending on countries in the sub-region, between 10% to 15% (Nasi, Cassagne, Billand, 2006) of the forests' surface area is occupied by protected areas ...

Forests, woods, forest plantations [PDF]

Forest@ - Rivista di Selvicoltura ed Ecologia Forestale, 2006
In protected areas the forest ecosystem management is directed to define the best approaches with high protection levels from ecological, historical, anthropological and landscape point of view. The conservation purposes have to be taken in consideration to not disturb the natural and functional processes, and therefore any forest human activity has to

Discovery and Targeted Proteomic Studies Reveal Striatal Markers Validated for Huntington's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Clinical trials for Huntington's disease (HD) enrolling persons before clinical motor diagnosis (CMD) lack validated biomarkers. This study aimed to conduct an unbiased discovery analysis and a targeted examination of proteomic biomarkers scrutinized by clinical validation. Methods Cerebrospinal fluid was obtained from PREDICT‐HD and

Predicting Epileptogenic Tubers in Patients With Tuberous Sclerosis Complex Using a Fusion Model Integrating Lesion Network Mapping and Machine Learning

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Accurate localization of epileptogenic tubers (ETs) in patients with tuberous sclerosis complex (TSC) is essential but challenging, as these tubers lack distinct pathological or genetic markers to differentiate them from other cortical tubers.
