A critical reappraisal of the carotid sinus and carotid bulb: Distinguishing neurohistological function from vascular geometry

The Anatomical Record, EarlyView.
This review redefines the carotid bulb (CB) as a variable geometric dilation shaped by hemodynamics and the carotid sinus (CS) as a conserved neurohistological baroreceptor field. Distinguishing these entities clarifies a century of anatomical confusion and links geometry, neurohistology, and clinical interpretation within a unified framework ...

The Transient Multidrug Resistance Phenotype of Salmonella enterica Swarming Cells Is Abolished by Sub-inhibitory Concentrations of Antimicrobial Compounds

Frontiers in Microbiology, 2017
Swarming motility is the rapid and coordinated multicellular migration of bacteria across a moist surface. During swarming, bacterial cells exhibit increased resistance to multiple antibiotics, a phenomenon described as adaptive or transient resistance ...

Ketogenic diet for infantile epileptic spasms

Epilepsia Open, EarlyView.
Abstract Approximately half of all cases of Infantile Epileptic Spasms Syndrome (IESS) do not respond to vigabatrin and hormonal therapies. There is no clear consensus as to the second‐line therapy for IESS. Ketogenic diet (KD) has emerged as an effective treatment for certain drug‐resistant epilepsies and in many cases of IESS.

The Hyperoxic-Hypoxic Paradox

Biomolecules, 2020
Effective metabolism is highly dependent on a narrow therapeutic range of oxygen. Accordingly, low levels of oxygen, or hypoxia, are one of the most powerful inducers of gene expression, metabolic changes, and regenerative processes, including ...

Intratumoral bacteria engineered for tumor therapy

Interdisciplinary Medicine, EarlyView.
This article comprehensively reviews engineered intratumoral bacteria used in tumor therapy. The concept development, characteristics, and engineering methods of intratumoral bacteria are summarized. The mechanisms and the translational significance by which engineered intratumoral bacteria interfere with tumor progression are discussed and highlighted.

Unusual Manifestations after a Case of Carotid Body Tumour Excision: A Case Report [PDF]

Journal of Krishna Institute of Medical Sciences University, 2018
Carotid body tumours are rare tumours arising from chemoreceptor cells at the bifurcation of carotid artery. They are highly vascular and mostly benign but with potential to turn into malignancy.

The transducer-like protein Tlp12 of Campylobacter jejuni is involved in glutamate and pyruvate chemotaxis

BMC Microbiology, 2018
Background Campylobacter jejuni is one of the most common bacterial causes of food-borne enteritis worldwide. Chemotaxis in C. jejuni is known to be critical for the successful colonization of the host and key for the adaptation of the microbial species ...

Potassium channel types in arterial chemoreceptor cells and their selective modulation by oxygen

The Journal of General Physiology, 1992
Single K+ channel currents were recorded in excised membrane patches from dispersed chemoreceptor cells of the rabbit carotid body under conditions that abolish current flow through Na+ and Ca2+ channels.

High‐throughput transcriptome mining and in silico screening reveal saccharide feeding stimulants for Cydia pomonella larvae

New Plant Protection, EarlyView.
We identified and characterized the gustatory and ionotropic receptors of Cydia pomonella using transcriptomics and in silico approaches, linking candidate sugar receptors to larval feeding attraction. Functional assays and behavioral tests highlighted isoquercitrin as a key feeding stimulant, providing a foundation for olfactory‐ and taste‐based pest ...

Research Progress on Upper Airway Cough Syndrome

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Upper airway cough syndrome (UACS) has been identified as a significant contributor to chronic cough in various national guidelines. However, the complexity of its pathogenesis, the lack of clarity surrounding its diagnostic criteria, and its overlap with other etiologies of chronic cough present considerable challenges in both diagnosis and ...
