J Exp Child Psychol 2021 Jun 9;210:105203. Epub 2021 Jun 9.

Department of Psychology, Lund University, 221 00 Lund, Sweden. Electronic address:

Background noise makes listening effortful and may lead to fatigue. This may compromise classroom learning, especially for children with a non-native background. In the current study, we used pupillometry to investigate listening effort and fatigue during listening comprehension under typical (0 dB signal-to-noise ratio [SNR]) and favorable (+10 dB SNR) listening conditions in 63 Swedish primary school children (7-9 years of age) performing a narrative speech-picture verification task.

A 48-Channel Receive Array Coil for Mesoscopic Diffusion-Weighted MRI of ex vivo Human Brain on the 3 T Connectome Scanner.

Neuroimage 2021 Jun 9:118256. Epub 2021 Jun 9.

Institute of Medical Physics and Radiation Protection (IMPS), TH-Mittelhessen University of Applied Sciences (THM), Giessen, Germany; Center for Mind, Brain and Behavior (CMBB), Marburg, Germany.

In vivo diffusion-weighted magnetic resonance imaging is limited in signal-to-noise-ratio (SNR) and acquisition time, which constrains spatial resolution to the macroscale regime. Ex vivo imaging, which allows for arbitrarily long scan times, is critical for exploring human brain structure in the mesoscale regime without loss of SNR. Standard head array coils designed for patients are sub-optimal for imaging ex vivo whole brain specimens. Read More

Circulating microRNA profile in humans and mice with congenital GH deficiency.

Aging Cell 2021 Jun 12:e13420. Epub 2021 Jun 12.

Burnett School of Biomedical Sciences, College of Medicine, University of Central Florida, Orlando, FL, USA.

Reduced inflammation, increased insulin sensitivity, and protection against cancer are shared between humans and mice with GH/IGF1 deficiency. Beyond hormone levels, miRNAs are important regulators of metabolic changes associated with healthy aging. We hypothesized that GH deficiency in humans alters the abundance of circulating miRNAs and that a subset of those miRNAs may overlap with those found in GH-deficient mice. Read More

What do surgeons need to know about the mesopancreas.

Langenbecks Arch Surg 2021 Jun 12. Epub 2021 Jun 12.

Department of Gastrointestinal Surgery, Hepatopancreatobiliary Unit, Presidente Dutra Hospital, São Luiz, Brazil.

Background: Pancreatoduodenectomy is the only treatment with a promise of cure for patients with pancreatic head adenocarcinoma, and a negative resection margin is an important factor related to overall survival. Complete clearance of the medial margin with removal of the so-called mesopancreas may decrease the recurrence rate after pancreatic resection. Here, we present some important information about the mesopancreas, total mesopancreas excision, and technical aspects to achieve negative resection margins. Read More

Constitutive Hedgehog/GLI2 signaling drives extracutaneous basaloid squamous cell carcinoma development and bone remodeling.

Carcinogenesis 2021 Jun 12. Epub 2021 Jun 12.

Department of Dermatology, University of Michigan, Ann Arbor, MI, USA.

Uncontrolled activation of the Hedgehog (Hh) signaling pathway, operating through GLI transcription factors, plays a central role in the pathogenesis of cutaneous basal cell carcinoma and contributes to the development of several malignancies arising in extracutaneous sites. We now report that K5-tTA;tetO-Gli2 bitransgenic mice develop distinctive epithelial tumors within their jaws. These tumors consist of large masses of highly proliferative, monomorphous, basaloid cells with scattered foci of keratinization and central necrosis, mimicking human basaloid squamous cell carcinoma (BSCC), an aggressive upper aerodigestive tract tumor.

Bleeding complications in patients with squamous cell carcinoma of the head and neck.

Head Neck 2021 Jun 12. Epub 2021 Jun 12.

Head and Neck Medical Oncology Unit, Fondazione IRCCS Istituto Nazionale dei Tumori, Milan, Italy.

Hemorrhage in recurrent and/or metastatic (R/M) head and neck squamous cell carcinoma (HNSCC) may be attributed to chemotherapy and local tumor irradiation. Evidence of the relationship between hemorrhage in R/M HNSCC and targeted therapies, including epidermal growth factor receptor (EGFR) and vascular endothelial growth factor (VEGF) inhibitors, or immune checkpoint inhibitors, is limited. We aimed to identify epidemiological and clinical data related to the occurrence of hemorrhage in R/M HNSCC and to explore its relationship with various therapies. Read More

Swallowing Exercise During Head and Neck Cancer Treatment: Results of a Randomized Trial.

Dysphagia 2021 Jun 11. Epub 2021 Jun 11.

Cancer Late Effects Research Unit (CASTLE), Department of Oncology, Copenhagen University Hospital Rigshospitalet, Blegdamsvej 9, 2100, Copenhagen, Denmark.

The diagnosis and treatment of head and neck cancer (HNC) can have substantial impact on swallowing function, nutritional balance, physical function and quality of life (QoL). Early initiated swallowing exercises are hypothesized to improve swallowing function in HNC patients. The aim was to investigate the effects of swallowing exercises and progressive resistance training (PRT) during radiotherapy on swallowing function, physical function and QoL in patients with pharynx-, larynx-, oral cavity cancer or unknown primary compared to usual care.

Head-to-head comparison of (R)-[C]verapamil and [F]MC225 in non-human primates, tracers for measuring P-glycoprotein function.

Eur J Nucl Med Mol Imaging 2021 Jun 11. Epub 2021 Jun 11.

Department of Nuclear Medicine and Molecular Imaging, University of Groningen, University Medical Center Groningen, Hanzeplein 1, 9713 GZ, Groningen, the Netherlands.

Purpose: P-glycoprotein (P-gp) function is altered in several brain disorders; thus, it is of interest to monitor the P-gp function in vivo using PET. (R)-[C]verapamil is considered the gold standard tracer to measure the P-gp function; however, it presents some drawbacks that limit its use. New P-gp tracers have been developed with improved properties, such as [F]MC225. Read More
