The 5-year overall survival was 87.1% for debulking surgery, 88.6% for radical resection and 26.6% for no surgical resection (P < .001). find more Lymph node metastases were associated with tumor size ≥5 cm (P = .006), malignant odontogenic histology (P = .025), and moderate/poor differentiation (P < .001).
In this large series of odontogenic cancers, any type of surgical resection was associated with improved survival. Lymph node metastases, although infrequent, were associated with significantly worse survival.

The learning curve associated with robotic pancreatoduodenectomy (RPD) is a hurdle for new programs to achieve optimal results. Since early analysis, robotic training has recently expanded, and the RPD approach has been refined. The purpose of this study is to examine RPD outcomes for surgeons who implemented a new program after receiving formal RPD training to determine if such training reduces the learning curve.
Outcomes for consecutive patients undergoing RPD at a single tertiary institution were compared to optimal RPD benchmarks from a previously reported learning curve analysis. Two surgical oncologists with formal RPD training performed all operations with one surgeon as bedside assistant and the other at the console.
Forty consecutive RPD operations were evaluated. Mean operative time was 354 ± 54 min, and blood loss was 300 ml. Length of stay was 7 days. Three patients (7.5%) underwent conversion to open. Pancreatic fistula affected five patients (12.5%). Operative time was stable over the study and lower than the reported benchmark. These RPD operative outcomes were similar to reported surgeon outcomes after the learning curve.
This study suggests formal robotic training facilitates safe and efficient adoption of RPD for new programs, reducing or eliminating the learning curve.

Mal de débarquement syndrome (MDDS) is characterized by a persistent rocking sensation, as though on a boat. It may occur following exposure to passive motion (motion-triggered MDDS [MT-MDDS]), or spontaneously (spontaneous-onset MDDS [SO-MDDS]). This study investigated the characteristics of MDDS patients with vestibular migraine (MDDS-VM) to those without (MDDS-O).
Retrospective review.
Retrospective, single-center study of 62 patients with MDDS. Clinical characteristics, Dizziness Handicap Inventory (DHI), Migraine Disability Assessment Score (MIDAS), job impact, and optimal treatment(s) were studied.
There were 23 MDDS-O (19 women), and 39 MDDS-VM (35 women) patients. Comparisons between MDDS-VM and MDDS-O showed significant differences in age of onset (41 vs. 52 years, P = .005), interictal visually induced dizziness (89.7% vs. 30.4%, P < .001), interictal head motion-induced dizziness (87.2% vs. 47.8%, P = .001), other vestibular sensations (59% vs. 13%, P < .001), interictal aural symptoms (25.6% vs. 0%, P = .008), number of interictal symptoms (4.3 vs. 2.3, P < .001), total DHI score (54.9 vs. 38.1, P = .005), DHI-P (physical domain) score (16.1 vs. 10, P = .004), DHI-F (functional domain) score (20.9 vs. 15.7, P = .016 MIDAS (4.6 vs. 32, P = .002), and job resignations (23.2% vs. 5%, P = .016). On the other hand, between-group comparisons for MT-MDDS and SO-MDDS did not reveal any significant differences whatsoever. For optimal treatment, venlafaxine was the most used (27.3%) in all groups. For MDDS-VM, antiepileptic drugs and migraine preventive vitamins were also useful in relieving symptoms.
MDDS-VM patients appear to be more disabled than MDDS-O, in terms of severity of dizziness, job impact, and number of symptoms, but have good potential for improvement, particularly with migraine prophylactic treatment.

Germination promotes changes in the composition of seeds by providing potential nutritional and health benefits compared with unsprouted seeds. This study investigated the influence of germination on the bioaccessibility and bioavailability of calcium in brown flaxseed (BF) and golden flaxseed (GF).
Germination did not influence the calcium levels of BF or GF, but the sprouted GF (SGF, 265.6 ± 12.9 mg) presented higher levels of calcium than the sprouted BF (SBF, 211.6 ± 3.20 mg). Tannin levels were similar among the groups (GF = 79.97 ± 3.49 mg; SGF = 78.81 ± 0.77 mg; BF = 81.82 ± 2.61 mg; SBF = 79.24 ± 4.58 mg), whereas phytate and oxalate levels decreased after germination. Germination reduced the phytatecalcium and oxalatecalcium molar ratios. In the in vitro study, germination increased calcium bioaccessibility (GF = 35.60 mg versus SGF = 41.45 mg; BF = 31.01 mg versus SBF = 38.84 mg). In the in vivo study, all groups present similar levels of urinary calcium (GF = 1.04 mg versus SGF = 2.06 mg; BF = y be due to the interaction with other compounds in the organism. © 2020 Society of Chemical Industry.Auxin regulates almost every aspect of plant growth and development and is perceived by the TIR1/AFB auxin co-receptor proteins differentially acting in concert with specific Aux/IAA transcriptional repressors. Little is known about the diverse functions of TIR1/AFB family members in species other than Arabidopsis. We created targeted OsTIR1 and OsAFB2-5 mutations in rice using CRISPR/Cas9 genome editing, and functionally characterized the roles of these five members in plant growth and development and auxinic herbicide resistance. Our results demonstrated that functions of OsTIR1/AFB family members are partially redundant in grain yield, tillering, plant height, root system and germination. Ostir1, Osafb2 and Osafb4 mutants exhibited more severe phenotypes than Osafb3 and Osafb5. The Ostir1Osafb2 double mutant displays extremely severe defects in plant development. All five OsTIR1/AFB members interacted with OsIAA1 and OsIAA11 proteins in vivo. Root elongation assay showed that each Ostir1/afb2-5 mutant was resistant to 2,4-dichlorophenoxyacetic acid (2,4-D) treatment.
