Gastric Cancer: Epidemiology, Risk Factors, Pathogenesis, Clinical Features, Diagnosis, and Management

MedComm, Volume 7, Issue 11, November 2026.
This comprehensive review summarizes gastric cancer epidemiology, multifactorial risk factors (like infectious, dietary, genetic), pathogenesis such as precancerous evolution, molecular alterations, and a focus on the bidirectional interactions between gastric cancer cells and macrophages in the tumor microenvironment.

Human brain matters: Navigating the neuropathology of COVID‐19

Brain Pathology, Volume 36, Issue 6, November 2026.
Severe COVID‐19 is associated with vascular dysregulation and chronic neuroinflammation, leading to axonal injury and neurodegeneration. In long COVID or PASC, persistent alterations in neuroimaging and biofluid biomarkers reflect ongoing neuronal damage and neuroinflammation, contributing to long‐term neurological symptoms including fatigue, cognitive

Brain viral reservoir seeding and neurological metabolic dysregulation in early‐life immunodeficiency virus infection

Brain Pathology, Volume 36, Issue 6, November 2026.
Brain viral reservoirs were undetectable in neonatal SIV during the first 3 days post infection; antiretroviral therapy (ART) at 3 dpi prevented brain reservoir seeding and normalized metabolic function, highlighting the necessity of very early treatment to protect the developing CNS.

Opioid Modulation of Major Neurotransmitter Systems: Acute, Chronic, and Withdrawal Effects

European Journal of Neuroscience, Volume 64, Issue 9, November 2026.
Opioids are widely used but also frequently misused drugs that affect multiple neurotransmitter systems, including dopaminergic, glutamatergic, GABAergic, serotonergic, and cholinergic pathways. Opioid‐induced neuroadaptations depend on the duration of drug exposure, with distinct changes also emerging following drug discontinuation.

Janus Reactivity of a Mononuclear Non‐Heme Iron(III)‐Peroxo Complex Toward Indole Oxidation

Angewandte Chemie, Volume 138, Issue 43, 19 October 2026.
The iron(III)‐peroxo complex [FeIII(O2)(12‐TMC)]+ exhibits bifurcating pathways in indole oxidation. N─H indoles undergo N─H H‐atom abstraction, supported by a KIE of 5.2 for N─H/N–D 2,3‐dimethylindoles, whereas N‐methylindoles react via electrophilic addition of the iron‐peroxo group to the C2–C3 double bond of the indole ring, forming iron ...
