Challenges in the Management of Massive Carotid Body Tumor
The carotid body paraganglioma is a rare benign neoplasm arising from the chemoreceptor cells of the carotid bulb. The carotid body has the largest collection of paraganglia in the head and neck with 60–70% of head and neck paraganglioma. Paraganglia are

GPCRs Direct Germline Development and Somatic Gonad Function in Planarians.
Planarians display remarkable plasticity in maintenance of their germline, with the ability to develop or dismantle reproductive tissues in response to systemic and environmental cues. Here, we investigated the role of G protein-coupled receptors (GPCRs)

The Enigmatic Canal-Associated Neurons Regulate Caenorhabditis elegans Larval Development Through a cAMP Signaling Pathway. [PDF]
Caenorhabditis elegans larval development requires the function of the two Canal-Associated Neurons (CANs): killing the CANs by laser microsurgery or disrupting their development by mutating the gene ceh-10 results in early larval arrest. How these cells

Abstract figure legend During 10 h exposures to normobaric hypoxia exposure there was a selective leftward shift in ventilatory response to hyperoxic hypercapnic rebreathing, but not the cerebrovascular response. The key findings are that the resetting of the central chemoreflex to lower PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_2}}}$ during early hypoxic ...

The genomes of two key bumblebee species with primitive eusocial organization [PDF]
Background: The shift from solitary to social behavior is one of the major evolutionary transitions. Primitively eusocial bumblebees are uniquely placed to illuminate the evolution of highly eusocial insect societies.

GABA Immunoreactivity in Chemoreceptor Cells of the Cat Carotid Body.
γ-Aminobutyric acid (GABA) immunoreactivities were found by immunohistochemistry in the chemoreceptor cells of the cat carotid body at the light microscopic level. The immunohistochemical process used consisted of a strept-avidin-biotin-peroxidase method. The immunostaining was mostly weak and appeared in about one-third of the cells.

Abstract figure legend Participants spent 13 days at high altitude (3800 m), where the reduced inspired oxygen pressure (↓PiO2$ \downarrow {P_{{\mathrm{i}}{{\mathrm{O}}_2}}}$) which elicited ventilatory acclimatization and increased inhibition of ventilation by transient hyperoxia (ΔV̇E$\Delta {\dot V_{\mathrm{E}}}$).

The full repertoire of Drosophila gustatory receptors for detecting an aversive compound. [PDF]
The ability to detect toxic compounds in foods is essential for animal survival. However, the minimal subunit composition of gustatory receptors required for sensing aversive chemicals in Drosophila is unknown.

Abstract figure legend Using wild‐type and Trpv1−/− rats, we assessed the contribution of TRPV1 channels to the activation of afferent renal nerve activity (ARNA) during renal artery occlusion, graded reductions in renal blood flow and elevated renal pelvic pressure.

Networked Chemoreceptors Benefit Bacterial Chemotaxis Performance
Motile bacteria use large receptor arrays to detect and follow chemical gradients in their environment. Extended receptor arrays, composed of networked signaling complexes, promote cooperative stimulus control of their associated signaling kinases. Here,
