Gut microbial metabolites in cancer immunomodulation

Molecular Cancer
Gut microbiota–derived metabolites are emerging as systemic “remote immunoregulators” that shape tumor immunity across tissues. Integrating evidence across short-chain fatty acids, tryptophan derivatives, secondary bile acids, polyamines and other ...

Power optimization in current mode circuits

, 2005
We propose a method to minimize power dissipation in current-mode CMOS analog and multiple-valued logic (MVL) circuits employing a stack of current comparators. First, we present an approximation model for current in a current comparator circuit.

Network Meta‐Analysis of Static Cold Storage Versus Dynamic Organ Preservation for Liver Transplantation

Artificial Organs, EarlyView.
Thirteen RCTs were included with a total of 1888 patients and assessed 5 interventions. Dynamic preservation of liver grafts was superior to SCS. HMP was superior to NMP for the primary outcomes. IFLT is a promising modality, but further clinical trials are required.

Novel approaches for drug development against chronic primary pain: A systematic review

British Journal of Pharmacology, EarlyView.
Abstract Chronic primary pain (CPP) persisting for more than 3 months, associated with significant emotional distress without any known underlying cause, is an unmet medical need. Traditional or adjuvant analgesics do not provide satisfactory pain relief for a great proportion of these patients.

Features of Schematic and Physical and Topological Design of Analog Integrated Comparators

, 2014
In practice, devices, which form either voltage with opposite polarity at the output at almost equal absolute values or voltage with the same polarity are the most widely used.

Natural product‐derived TRPM7 channel inhibitors in neurological injury: Mechanisms, pharmacological potential and translational challenges

British Journal of Pharmacology, EarlyView.
Disruption of intracellular ionic homeostasis is a convergent pathological feature across diverse neurological injuries and disorders, including ischaemic and haemorrhagic stroke, hypoxic–ischaemic brain injury, traumatic brain injury, epilepsy and brain tumour.

Reduced Risk of MASLD and Cardiometabolic Disease Following Renal Denervation Therapy in Patients With Resistant Hypertension

Diabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Introduction Autonomic dysfunction increases the risk of cardio‐kidney‐metabolic (CKM) syndrome including metabolic dysfunction‐associated steatotic liver disease (MASLD), type 2 diabetes (T2D), cardiovascular disease (CVD) and chronic kidney disease (CKD).
