BACKGROUND: More than 50% of patients with major depressive episode (MDE) fail to respond to initial treatment with first line pharmacological therapy. Altered receptor and serotonin transporter function are considered to be associated with mental disorders. Our investigation aimed on the density of the HT1A receptor in mesiotemporal cortex (MTC) and raphe measured by F18-Mefway in patients with MDD. METHODS: Patients with untreated clinically suspected major depressive episode were recruited from June 2012 to May 2014...

In this dynamic causal modeling (DCM) study, we evaluated the effect of age on the effective connectivity of a cerebral network involved in lexical production. Younger and older adults performed an object naming task during fMRI. The DCM was used to explore the interactions between four regions of interest: the occipital cortex, OC; the lateral temporal cortex, LTC; the medial temporal cortex, MTC; and the inferior frontal cortex, IFC. We mainly focused on the modulation of the fronto-temporal interaction, according to the hypothesis that aging requires strategies that modulate the access to the semantic knowledge, either through a neural reserve mechanism (increased MTC-LTC connectivity) or through a neural compensation mechanism (supplementary IFC-MTC connectivity)...

Sepsis-induced acute kidney injury (SAKI) is a major complication of kidney disease associated with increased mortality and faster progression. Therefore, the development of imaging biomarkers to detect septic AKI is of great clinical interest. In this study, we aimed to characterize the endogenous chemical exchange saturation transfer (CEST) MRI contrast in the lipopolysaccharide (LPS)-induced SAKI mouse model and to investigate the use of CEST MRI for detecting such injury. We used a SAKI mouse model that was generated by i...

Hyalinizing trabecular tumor (HTT) is a rare thyroid tumor with low to minimal malignant potential. HTT is often misinterpreted as other thyroid tumors, including papillary thyroid carcinoma (PTC) and medullary thyroid carcinoma (MTC), on fine-needle aspiration (FNA) cytology, because of its overlapping cytologic features, such as nuclear grooves and intranulcear pseudoinclusions. Although cytopathologists cannot definitely conclude HTT by FNA cytology, suspicion of HTT is necessary to avoid misdiagnosing HTT as PTC or MTC and to avoid unnecessary aggressive treatment...

Medullary Thyroid Carcinoma (MTC) is a rare neoplasia derived from neural parafollicular C cells. MicroRNAs (miRNAs) are small regulatory RNAs with essential roles in the biology of cancers such as MTC and can be applied as diagnostic markers. According to previous studies, miR-144 and miR-34 and their two oncogenes target, mammalian target of rapamycin (mTOR) and AXL receptor tyrosine kinase (AXL), were selected for further investigations in our study. Thirty MTC samples as well as thirty adjacent normal thyroid tissues were applied in this study including 28 Formalin-Fixed Paraffin-Embedded (FFPE) and 2 fresh-frozen MTC samples...

PURPOSE: To delineate risk factors for, and examine temporal patterns of, histology-proven recurrent medullary thyroid cancer (MTC) after compartment-oriented surgery. METHODS: Multivariate Cox regression on overall, node, and soft tissue infiltrate recurrence per previously dissected neck compartment. RESULTS: Mean follow-up for the 203 (and 158) patients with central (and ipsilateral lateral) neck dissection was 56.1 months. On multivariate Cox regression, tumor size > 20 mm predicted overall and node recurrence in the central neck, whereas extranodal growth predicted overall and node recurrence in the ipsilateral lateral neck...

BACKGROUND: The management of trauma patients has changed radically in the last decade and studies have shown overall improvements in survival. However, reduction in mortality for the many may obscure a lack of progress in some high-risk patients. We sought to examine the outcomes for hypotensive patients requiring laparotomy in UK military and civilian cohorts. METHODS: We undertook a review of two prospectively maintained trauma databases; the UK Joint Theatre Trauma Registry (JTTR) for the military cohort (4th February 2003 to 21st September 2014), and the trauma registry of the Royal London Hospital MTC (1st January 2012 to 1st January 2017) for civilian patients...

OBJECTIVE: Medullary thyroid carcinoma (MTC) is a rare thyroid malignancy originating from parafollicular C-cells with the potential for aggressive behavior. The extent of lymph node (LN) dissection at the time of surgery is controversial, with different schools of thought prevailing. Some systematically perform LN dissections, whereas others base their decision on radiologic evidence of disease and some with the assistance of pre-operative calcitonin (CT) levels. METHODS: We retrospectively assessed the correlation between pre-operative CT levels and clinico-pathologic factors among 42 patients with MTC between 1994 and 2015...

Chemical exchange saturation transfer (CEST), arterial spin labeling (ASL), and magnetization transfer contrast (MTC) methods generate different contrasts for MRI. However, they share many similarities in terms of pulse sequences and mechanistic principles. They all use RF pulse preparation schemes to label the longitudinal magnetization of certain proton pools and follow the delivery and transfer of this magnetic label to a water proton pool in a tissue region of interest, where it accumulates and can be detected using any imaging sequence...

The olfactory bulb (OB) transforms sensory input into spatially and temporally organized patterns of activity in principal mitral (MC) and middle tufted (mTC) cells. Thus far, the mechanisms underlying odor representations in the OB have been mainly investigated in MCs. However, experimental findings suggest that MC and mTC may encode parallel and complementary odor representations. We have analyzed the functional roles of these pathways by using a morphologically and physiologically realistic three-dimensional model to explore the MC and mTC microcircuits in the glomerular layer and deeper plexiform layer...
