A simple index for assessing cumulative human impacts on mountain lakes

Limnology and Oceanography: Methods, EarlyView.
Abstract Mountain lakes are highly sensitive ecosystems and effective sentinels of environmental change, yet the exposure and magnitude of the human footprint remain poorly quantified. In this study, we develop a simple and non‐invasive abiotic index to assess cumulative pressures on mountain lakes. The proposed index integrates eight variables grouped

Poly(O‐Propargyl‐N‐Amino Carbamate), a Reactive Polymer to Underpin Biomedical Applications of Poly(acetylene)s

Macromolecular Rapid Communications, EarlyView.
We report here a new methodology to prepare functional poly(acetylene)s under aqueous conditions. This methodology is underpinned by poly(O‐propargyl‐N‐amino carbamate) (P1), a reactive poly(acetylene) carrying acyl hydrazines. Thus, P1 reacts with aldehydes to give functional poly(acetylene)s, including cationic, hydrophobic, and sugar‐loaded poly ...

Coping Behavior in Patients with Parkinson's Disease Prior to Subthalamic Deep Brain Stimulation and Association with Psychiatric Symptoms, Quality of Life and Neuropsychological Status

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Coping behavior of Parkinson's disease (PD) patients undergoing subthalamic Deep Brain Stimulation (STN‐DBS) is poorly understood. Identifying patients with ineffective coping could help prepare them better for surgery. Objectives To clarify coping of PD patients preoperatively and the relation with psychiatric symptoms, quality of ...

Gender, Stereotypes, and Competitive Performance Gap: An Experimental Investigation

Managerial and Decision Economics, EarlyView.
ABSTRACT This study investigates how participants in competition react to gender stereotypes in performance. We propose two novel gender‐oriented tasks: clicking as a male‐oriented task and face recall as a female‐oriented task with two treatment conditions, which can strengthen shared gender stereotypes and foster gender competition.

Progression of Motor and Cognitive Functions in Isolated REM Sleep Behavior Disorder: A 7‐Year Prospective Matched Cohort Study

Movement Disorders, EarlyView.
Abstract Background Although clinical markers (eg, motor and cognitive impairment) in isolated rapid eye movement sleep behavior disorder (iRBD) are associated with faster phenoconversion, their longitudinal trajectory patterns (linear or nonlinear) remain unclear.

A Severity‐Agnostic Atrophy Pattern in Spinocerebellar Ataxia Type 3: Volumetrics from ENIGMA‐Ataxia

Movement Disorders, EarlyView.
Background Spinocerebellar ataxia type 3 (SCA3) is a rare, inherited neurodegenerative disease characterized by progressive loss of motor coordination. Objectives We undertook a multisite magnetic resonance imaging study to profile the spatial spread of atrophy across the brain, determine whether atrophy preferentially maps onto specific functional ...
