Polymer crystal-melt interfaces and nucleation in polyethylene [PDF]

, 2010
Kinetic barriers cause polymers to crystallize incompletely, into nanoscale lamellae interleaved with amorphous regions. As a result, crystalline polymers are full of crystal-melt interfaces, which dominate their physical properties.

Metformin as a Multifaceted Therapeutic Agent for Gastrointestinal Diseases: Mechanisms, Clinical Efficacy, and Future Directions

Pharmacology Research &Perspectives, Volume 14, Issue 3, June 2026.
ABSTRACT The high prevalence of gastrointestinal (GI) diseases and their significant impact on the quality of life require new therapeutic strategies. The development of novel therapeutic strategies should prioritize targeting the fundamental pathophysiological mechanisms underlying these diseases, including inflammation, cellular proliferation, and ...

Deleting adipose FXR exacerbates metabolic defects and induces endocannabinoid lipid, 2-oleoyl glycerol, in obesity

Journal of Lipid Research
The nutrient sensor farnesoid X receptor (FXR) transcriptionally regulates whole-body lipid and glucose homeostasis. Several studies examined targeting FXR as a modality to treat obesity with varying conflicting results, emphasizing the need to study ...

Metformin promotes mitochondrial integrity through AMPK‐signaling in Leber's hereditary optic neuropathy

FEBS Open Bio, Volume 16, Issue 5, Page 885-905, May 2026.
Metformin mediates mitochondrial quality control in Leber's hereditary optic neuropathy (LHON) fibroblasts carrying mtDNA mutations. At therapeutic levels, metformin activates AMPK signaling to restore mitochondrial dynamics by promoting fusion and restraining fission, while preserving mitochondrial mass, enhancing autophagy/mitophagy and biogenesis ...

Multicohort Validation of Gut Microbiome Signatures for Cholangiocarcinoma Diagnosis and Functional Characterization of Bifidobacterium Pseudocatenulatum

Advanced Science, Volume 13, Issue 27, 13 May 2026.
This study analyzes gut bacteria in cholangiocarcinoma patients, revealing distinct microbial signatures that enable accurate disease detection. Species‐based diagnostic models achieved over 98% accuracy in identifying cholangiocarcinoma and distinguished it from other liver diseases. The research demonstrates that specific beneficial bacteria suppress

A geometric characterization of c-optimal designs for heteroscedastic regression [PDF]

We consider the common nonlinear regression model where the variance as well as the mean is a parametric function of the explanatory variables. The c-optimal design problem is investigated in the case when the parameters of both the mean and the variance
