Ashwagandha: Is It Safe? Part 2: A Preclinical Evidence Review

Phytotherapy Research, EarlyView.
ABSTRACT The preclinical evidence for the safety of ashwagandha (Withania somnifera (L.) Dunal, AS) is reviewed, and its preparations (extracts) and constituents, from the general toxicity in animal models to in vitro and cell culture studies, which may elucidate mechanisms of action and explain clinical case reports.

Opportunity cost estimates for spatial conservation prioritisation across terrestrial Europe

Scientific Data
Opportunity costs of conservation represent the foregone economic benefits from using land for nature conservation rather than alternative activities. Considering opportunity costs therefore helps in identifying cost-effective solutions in conservation ...

Safety of 12‐Months Administration of Ashwagandha (Withania somnifera) Standardized Root Extract in Healthy Adults: A Prospective, Observational Study

Phytotherapy Research, EarlyView.
ABSTRACT Ashwagandha, an adaptogen, is an important herb of Ayurveda used as a Rasayana for its various health benefits. This prospective, multi‐center, observational clinical study evaluates the safety (clinical and laboratory) of a standardized Ashwagandha Root Extract (ARE) on long‐term administration over 12 months. Male and female adults (N = 191)

Global sustainability scenarios lead to regionally different outcomes for terrestrial biodiversity

Environmental Research Letters
Mitigating climate change (CC) and reversing biodiversity decline are urgent and interconnected global priorities. Strategies to address both crises must consider the relationships, synergies and trade-offs between key response measures, including ...

Dynamics and model representation of two contrasting extreme precipitation events in the Sahel

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Hovmöller diagrams of the two investigated extreme precipitation events in Mali are shown for (i) IMERG observations, and ICOsahedral Nonhydrostatic model (ICON) runs with parameterization of explicit convection (ii) enabled and (iii) disabled. This work highlights that the commonly perceived benefit of using explicit convection in a state‐of‐the‐art ...

Pengaruh Problem-Based Learning (PBL) terhadap Keterampilan Berpikir Kritis

Jurnal Pendidikan: Teori, Penelitian, dan Pengembangan, 2018
Geography learning in high school has not been able to develop critical thinking skills, various problems in learning are considered as a boring subject so as less stimulate learners to think critically and less able to solve problems. This study aims to

Mesoscale and microphysical processes leading to extreme hourly rainfall prior to the merger of two mesoscale convective systems in Central China

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Short‐term extreme rainfall can be produced by the variation of low‐level warm moist airflow during mesoscale convective systems (MCSs) approaching another. The cold outflow of the rapidly moving MCS intensifies the warm moist airflow in front, enhancing the convergence and ascending motion in the quasi‐stationary MCS.

Covariance of the intertropical discontinuity and African easterly jet in Sahelian wet and dry years

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Intertropical discontinuity and African easterly jet (AEJ) positions are strongly correlated, with a more pronounced linear relationship across wet years. Surface heat flux anomalies modify low‐level temperature and sensible heat flux gradients that shift the AEJ core south of the gradient maxima in both composites.
