Circulating omega-7 fatty acids are differentially related to metabolic dysfunction and incident type II diabetes: the Multi-Ethnic Study of Atherosclerosis (MESA).
CONCLUSIONS: Results suggest that plasma vaccenic acid and palmitoleic acid are markers of metabolic health and dysfunction, respectively. Coupled with previous evidence and the significant race interactions, our findings have implications for future studies of the race-based differences in omega-7 fatty acids and their regulation in the context of deteriorating metabolic health.

A review of biological functions, health benefits, and possible de novo biosynthetic pathway of palmitoleic acid in macadamia nuts
Publication date: November 2019Source: Journal of Functional Foods, Volume 62Author(s): Wei Hu, Melissa Fitzgerald, Bruce Topp, Mobasher Alam, Tim J. O'HareAbstractPalmitoleic acid is an unusual omega-7 monounsaturated fatty acid that occurs naturally in high levels in macadamia plants. Due to its wide public acceptance and being a commonly occurring food, macadamia nuts may serve as an important dietary agent for the delivery of palmitoleic acid to the human body. This review focuses on discussing the biological functions of palmitoleic acid, the association of palmitoleic acid with various diseases, as well as the antici...

Design and Modeling of a Three-Degree-of-Freedom Articulating Robotic Microsurgical Forceps for Trans-Oral Laser Microsurgery
Trans-oral laser microsurgery (TLM) is a surgical procedure for removing malignancies (e.g., cysts, polyps, tumors) of the laryngeal region through laser ablation. Intraoperative microsurgical forceps (i.e., microforceps) are used for tissue manipulation. The microforceps are rigid, single degree-of-freedom (DOF) devices (open –close) with precurved jaws to access different parts of the curved cylindrical laryngeal region. These microforceps are manually handled and are subject to hand tremors, poor reachability, and nonergonomic use, resulting in poor efficacy and efficiency in the surgery. A novel 3DOF motorized micro ...

A robotic microsurgical forceps for transoral laser microsurgery
ConclusionsRMF-2F offers an ergonomic and intuitive interface for intraoperative tissue manipulation in TLM. The device performance, usability, and haptic feedback capability were positively evaluated by users as well as expert surgeons. RMF-2F introduces the benefits of robotic teleoperation including, (i) overcoming hand tremors and wrist excursions, (ii) improved reachability and accuracy, and (iii) tissue gripping feedback for safe tissue manipulation.

Impact of perinatal exposure to sucrose or high fructose corn syrup (HFCS-55) on adiposity and hepatic lipid composition in rat offspring.
This study suggests that the type of sugar and the timing of exposure (prenatal or suckling periods) are both important for determining the impact on metabolic health outcomes in the offspring. This article is protected by copyright. All rights reserved.

Effect of Cis-palmitoleic acid (an omega-7 fatty acid) supplementation on inflammation and expression of HNF4 γ, HNF4α and IL-6 in patients with ulcerative colitis: a double-blind, randomized pilot study.
CONCLUSIONS: Cis-palmitoleic acid as co- adjuvant therapy for 8 weeks seems to decrease the inflammatory activity through the increased expression of HNF4α and HNF4γ in patients with UC.

Serum fatty acids in infants, reflecting family fish consumption, were inversely associated with allergy development but not related to farm residence
ConclusionThe allergy‐protective effect of farming was not linked to infant serum fatty acid composition. However, healthy infants had higher proportions of EPA in their sera, probably reflecting a family diet rich in fish, compared to subsequently allergic children. (Source: Acta Paediatrica)

Dihydroceramide-desaturase-1-mediated caspase 9 activation through ceramide plays a pivotal role in palmitic acid-induced HepG2 cell apoptosis
In this study, results showed that the inhibition of PA-induced HepG2 cell growth takes place in a time- and concentration-dependent manner, that activation of caspase 9 is necessary for PA-induced HepG2 cell apoptosis, that dihydroceramide desaturase 1 (DES1) plays a key role in PA-mediated caspase 9 and caspase 3 activation, and that palmitoleic acid (POA), an omega-7 monounsaturated fatty acid, reverses PA-induced apoptosis through DES1 → Ceramide → Caspase 9 → Caspase 3 signaling.

Sensors, Vol. 16, Pages 395: Fusion of Haptic and Gesture Sensors for Rehabilitation of Bimanual Coordination and Dexterous Manipulation
Disabilities after neural injury, such as stroke, bring tremendous burden to patients, families and society. Besides the conventional constrained-induced training with a paretic arm, bilateral rehabilitation training involves both the ipsilateral and contralateral sides of the neural injury, fitting well with the fact that both arms are needed in common activities of daily living (ADLs), and can promote good functional recovery. In this work, the fusion of a gesture sensor and a haptic sensor with force feedback capabilities has enabled a bilateral rehabilitation training therapy. The Leap Motion gesture sensor detects the...

Oral administration of omega-7 palmitoleic acid induces satiety and the release of appetite-related hormones in male rats.
Abstract
We have analyzed the effect of palmitoleic acid on short-term food intake in male rats. Administration of omega-7 palmitoleic acid by oral gavage significantly decreased food intake compared to palmitic acid, omega-9 oleic acid, or a vehicle control. Palmitoleic acid exhibited a dose-dependent effect in this context and did not cause general malaise. A triglyceride form of palmitoleate also decreased food intake, whereas olive oil, which is rich in oleic acid, did not. Palmitoleic acid accumulated within the small intestine in a dose-dependent fashion and elevated levels of the satiety hormone cho...
