Innovations in Obesity Treatment: Beyond Adipose Tissue Dysfunction

Obesity Reviews, EarlyView.
Obesity drives chronic inflammation, insulin resistance, type 2 diabetes, and cancer development through adipocyte dysfunction. Addressing this multisystemic disorder requires integrated strategies beyond diet and exercise, such as thermogenesis activation via menthol or capsinoids and appetite control through GLP‐1/GIP agonists and neuromodulation to ...

Intermittent theta burst stimulation to extend early ketamine response in treatment‐resistant depression: A preliminary enriched randomized, double‐blind, sham‐controlled trial

Psychiatry and Clinical Neurosciences, EarlyView.
Background Ketamine produces rapid antidepressant effects in treatment‐resistant depression (TRD), but these benefits diminish within days. Whether intermittent theta‐burst stimulation (iTBS) can sustain ketamine response and whether such effects are associated with changes in large‐scale brain networks are unclear.

Power factor correction capacitors; essentials and cautions [PDF]

, 2000
In electrical installations with a low power factor, significant cost savings can be made through the application of power factor correction. These savings are achieved largely due to the way electrical utilities bill their customers.

Placebo and nocebo effects on pain through the lens of the predictive brain: Neurobiological mechanisms and translational implications

Experimental Physiology, EarlyView.
Abstract Placebo and nocebo effects on pain provide a model for investigating how cognitive and contextual factors modulate the physiological processes underlying nociception and its regulation. However, existing accounts remain fragmented and lack a unifying mechanistic framework linking brain, behaviour and autonomic responses.

Comparative Analysis of the First‐Eight Nationally Determined Contributions: Lessons for NDC3.0 Developers in Africa

Climate Resilience and Sustainability, Volume 5, Issue 2, December 2026.
This study reviews the first eight NDC3 submissions (Zambia, Zimbabwe, Lesotho, Japan, New Zealand, Canada, the United Kingdom, and Switzerland), comparing reference points, timeframes, scope, methodologies, ambition, and adaptation indicators. Results show strong mitigation ambition in developed countries but persistent adaptation and implementation ...
