Function enrichment analysis showed NTF3 was involved in cell motion and MAPK signaling pathway; ITGA7 affected extracellular matrix (ECM)-receptor interaction; GNG2 participated in cell proliferation and chemokine signaling pathway. In conclusion, miRNAs regulating the expressions of NTF3, GNG2 and ITGA7 may represent underlying targets for treatment of AAA.
To determine the association between pathologic features and molecular classes (BRAF-like, RAS-like, and non-BRAF-like non-RAS-like [NBNR]).

Retrospective review of a merged database containing 676 patients, 84% (571/676) were assigned to a molecular class from publicly accessible sequenced data of thyroid neoplasms.

The merged cohort included 571 neoplasms 353 (62%) BRAF-like, 172 (30%) RAS-like, and 46 (8.1%) NBNR. Lymph node metastasis (any N1 disease) was present in 166/337 (49%) of BRAF-like, 23/164 (14%) of RAS-like, and 0/46 (0%) of NBNR and are significantly different (P < .001). Gross extra-thyroidal extension was observed in 27 patients, including 24/331 (7%) of BRAF-like, 2/160 (1%) of RAS-like, and 1/46 (2%) of NBNR (P = .01). N1B lymph node metastases or T4 disease was present in 74/333 (22%) of BRAF-like, 10/160 (6%) of RAS-like, and 1/46 (2%) of NBNR (P < .0001). Distant metastasis was present in 4/151 (2.6%) of BRAF-like, 2/50 (4%) of RAS-like and 0/46 for NBNR (P = .627). Angioinvecular mutations in thyroid tumors aids in decision-making regarding extent of surgery.
To examine risk factors that might be associated with thyroid eye disease (TED) in patients with Graves' disease (GD), which may guide physicians in the prevention and management of TED.

Medline and Embase were searched for articles discussing risk factors of TED. Comparisons were made between GD patients with and without TED, and between active and inactive TED GD patients. Weighted mean differences (WMDs) and odds ratios (ORs) were determined for continuous and dichotomous outcomes, respectively. Results were pooled with random effects using the DerSimonian and Laird model.

Fifty-six articles were included in the analysis. Smoking, inclusive of current and previous smoking status, was a significant risk factor for TED (OR 2.401; CI 1.958-2.945; P < .001). Statistical significance was found upon meta-regression between male sex and the odds of smoking and TED (β= 1.195; SE= 0.436; P= .013). Other risk factors were also examined, and patients with TED were significantly older than those without TED (WMD 1.350; CI 0.328-2.372; P= .010). While both age (WMD 5.546; CI 3.075-8.017; P < .001) and male sex (OR 1.819; CI 1.178-2.808; P= .007) were found to be significant risk factors for active TED patients compared to inactive TED patients, no statistical significance was found for family history, thyroid status, cholesterol levels, or body mass index.

Factors such as smoking, sex, and age predispose GD patients to TED, and TED patients to active TED. A targeted approach in the management of GD and TED is required to reduce the modifiable risk factor of smoking.

Mobile genetic elements are responsible for much of horizontal gene transfer and also carry beneficial cargo genes. Uncovering strategies used by mobile genetic elements to benefit host cells is crucial for understanding their stability and spread in populations. We describe a benefit that ICEBs1, an integrative and conjugative element of Bacillus subtilis, provides to its host cells. Activation of ICEBs1 conferred a frequency-dependent selective advantage to host cells during two different developmental processes biofilm formation and sporulation. These benefits were due to inhibition of biofilm-associated gene expression and delayed sporulation by ICEBs1-containing cells, enabling them to exploit their neighbors and grow more prior to development. A single ICEBs1 gene, devI (formerly ydcO), was both necessary and sufficient for inhibition of development. Manipulation of host developmental programs allows ICEBs1 to increase host fitness, thereby increasing propagation of the element.Calmodulin (CaM) engages in Ca2+-dependent interactions with numerous proteins, including a still incompletely understood physical and functional interaction with the human Na+/H+-exchanger NHE1. Using nuclear magnetic resonance (NMR) spectroscopy, isothermal titration calorimetry, and fibroblasts stably expressing wildtype and mutant NHE1, we discovered multiple accessible states of this functionally important complex existing in different NHE1CaM stoichiometries and structures. We determined the NMR solution structure of a ternary complex in which CaM links two NHE1 cytosolic tails. In vitro, stoichiometries and affinities could be tuned by variations in NHE1CaM ratio and calcium ([Ca2+]) and by phosphorylation of S648 in the first CaM-binding α-helix. In cells, Ca2+-CaM-induced NHE1 activity was reduced by mimicking S648 phosphorylation and by mutation of the first CaM-binding α-helix, whereas it was unaffected by inhibition of Akt, one of several kinases phosphorylating S648. Our results demonstrate a diversity of NHE1CaM interaction modes and suggest that CaM may contribute to NHE1 dimerization and thereby augment NHE1 regulation. We propose that a similar structural diversity is of relevance to many other CaM complexes.On 15 October, 2020, Dr. Paul M. Weinberg, a true giant in the field of paediatric cardiology, succumbed to a prolonged illness. Dr. Weinberg had a 43-year career and was described as a pillar of The Children's Hospital of Philadelphia and the spirit of the Division of Cardiology, a cherished and beloved teacher, and an outstanding clinician. His impact on the field and on the careers of his students will be remembered for generations to come.In 2019, Dr. Weinberg wrote for Jefferson Medical School's 50th year reunion memory book "In the true spirit of Hippocrates, I seek to mentor the next generation as I was mentored by the last, without expectation of reward. I am forever indebted to these educators for all the knowledge they imparted to me and for the wisdom that I acquired under their tutelage." These words are a true reflection of his unassuming dedication to teaching the next generation of paediatric cardiologists. His legacy will continue to live on through these trainees and impact the field for generations to come.
