Powered lower limb prostheses have the ability to provide greater mobility for amputee patients. Such prostheses often have pre-programmed modes which can allow activities such as climbing stairs and descending ramps, something which many amputees struggle with when using non-powered limbs. Previous literature has shown how pattern classification can allow seamless transitions between modes with a high accuracy and without any user interaction. Although accurate, training and testing each subject with their own dependent data is time consuming...

Obstructive Sleep Apnea (OSA) is a sleep disorder highly prevalent in the general population. Cardiorespiratory Phase Synchronization (CRPS) is a form of non-linear interaction between respiratory and cardiovascular systems that was found to be reduced in severe OSA patients. The Hilbert Transform (HT) method was the recommended choice for estimating the respiratory phase in CRPS studies. But we have noticed that HT provides a phase that is aligned to the transition between the exhalation and the inhalation parts of different breathing cycles, instead of being aligned to the breathing onsets...

Pulse transit time (PTT) has been widely studied as an index of blood pressure (BP) changes. In recent years, some prototypes of PTT-based wearable BP measurement devices have been developed, which can relieve users from the discomfort caused by the inflating cuff used in auscultatory and oscillometric BP measurement techniques. However, in the common practice for PTT detection, multi-site sensor implementation on human body is required, making it difficult for the integration of wearable devices. Since multi-wavelength (MW) photoplethysmogram (PPG) signals carry blood pulsation information of different blood vessels embedded in different skin depths, the time difference between different wavelength PPG signals collected at the same body site can be treated as a special PTT on a short length of blood vessels beneath the skin...

As the number of speech-language pathologists (SLPs) responsible for swallowing and feeding services in the educational setting increases, guidance informing this specialized practice continues to emerge. Although SLPs have provided dysphagia management for children in medical settings for many years, the extension of dysphagia services to the schools is comparatively new. This shift in care delivery for what was previously a hospital-based practice is now occurring more frequently, and in an environment void of extensive medical supports (i...

The rapid progress in medical and technical innovations in the neonatal intensive care unit (NICU) has been accompanied by concern for outcomes of NICU graduates. Although advances in neonatal care have led to significant changes in survival rates of very small and extremely preterm neonates, early feeding difficulties with the transition from tube feeding to oral feeding are prominent and often persist beyond discharge to home. Progress in learning to feed in the NICU and continued growth in feeding skills after the NICU may be closely tied to fostering neuroprotection and safety...

BACKGROUND: Androgenic alopecia (AGA) occurs as a result of the contraction of the anagen phase because of the action of androgens on hair follicles. TGF-β production from dermal papillae is enhanced by androgens, and growth inhibition of hair-follicle cells is induced by TGF-β, and the hair cycle progresses from the anagen phase to the catagen phase. We investigated both the in vitro and in vivo potency of the newly identified ALK5 inhibitor TP0427736 {6-[4-(4-methyl-1,3-thiazol-2-yl)-1H-imidazol-5-yl]-1,3-benzothiazole}...

In this work, luminescent emissions of beta-calcium pyrophosphate doped with terbium ions (β-Ca2P2O7:Tb(3+)) were studied. The Ca2P2O7:Tb(3+) powders were prepared by precipitation and annealed at 900°C for 2h was applied on the powders to observe the beta phase. Radioluminescence measurements showed emission bands related with (5)D3 ((5)D4)→(7)FJ transitions of Tb(3+) ions. Three overlapped peaks at 126, 165 and 220°C were observed in thermoluminescence response. A linear TL dose-response in the range of 0...

Using data from the National Longitudinal Study of Adolescent to Adult Health, this study examines the relationship between significant changes in neighbourhood poverty during the transition to adulthood and shifts in depressive symptoms. We found that associations between changes in neighbourhood poverty and mental health disappeared after controlling for contemporaneous life course events, specifically transitions associated with intimate relationship building and human capital formation. The exception is a decrease in depressive symptoms for females moving into lower poverty neighbourhoods across the entire transition to adulthood period...

REVIEW
Abd Rashid Bin Mohd Yusoff, Aron J Huckaba, Mohammad Khaja Nazeeruddin
The development of transition metal complexes for application in light-emitting devices is currently attracting significant research interest. Among phosphorescent emitters, those involving iridium (III) complexes have proven to be exceedingly useful due to their relatively short triplet lifetime and high phosphorescence quantum yields. The emission wavelength of iridium (III) complexes significantly depends on the ligands, and changing the electronic nature and the position of the ligand substituents can control the properties of the ligands...

The properties of self-avoiding p-atic membranes restricted to spherical topology have been studied by Monte Carlo simulations of a triangulated random surface model. Spherically shaped p-atic membranes undergo a Kosterlitz-Thouless transition as expected with topology induced mutually repelling disclinations of the p-atic ordered phase. For flexible membranes the phase behaviour bears some resemblance to the spherically shaped case with a p-atic disordered crumpled phase and p-atic ordered, conformationally ordered (crinkled) phase separated by a KT-like transition with proliferation of disclinations...

Cyclosporine-A (CsA) induces gingival overgrowth. Cyclosporine's anti-apoptotic activity in human gingival fibroblast is due to desensitization of mitochondrial permeability transition pore (MPTP) and augmentation of anti-apoptotic, Bcl2. Alternative mechanisms of apoptosis exist involving enzymes like calcium-dependent Calpain and signaling events related to apoptosis, like Glycogen synthase kinase 3β (GSK3β) and protein kinase A (PKA). Cyclosporine-A in renal tubular cells induces endoplasmic reticulum stress (ER stress) which has not been explored in gingival overgrowth...

Situations in which one partner is interested in having sex but the other partner is not "in the mood" are common in relationships. We extend previous work on sexual communal strength-the motivation to be responsive to a partner's sexual needs-to demonstrate that in addition to the motivation to meet a partner's need to have sex, the motivation to be understanding about a partner's need not to engage in sex is uniquely associated with sexual and relationship satisfaction. In Study 1, we adapted a measure of sexual communal strength for having sex (SCSS) to create a new measure of sexual communal strength for not having sex (SCSN)...

Along with the periodic reductions in O2 requirements of mammalian hibernators during winter, the O2 affinity of the blood of mammalian hibernators is seasonally regulated to help match O2 supply to consumption, contributing to limit tissue oxidative stress, particularly at arousals. Specifically, mammalian hibernators consistently show an overall increase in the blood-O2 affinity, which causes a decreased O2 unloading to tissues, while having similar or lower tissue O2 tensions during hibernation. This overview explores how the decreased body temperature and concentration of red blood cell 2,3-diphosphoglycerate (DPG) that occur in hibernation contribute separately or in combination to the concurrent increase in the O2 affinity of the hemoglobin, the O2 carrier protein of the blood...

During human pregnancy, cytotrophoblasts (CTBs) play key roles in uterine invasion, vascular remodeling, and anchoring of the feto-placental unit. Due to the challenges associated with studying human placentation in utero, cultured primary villous CTBs are used as a model of the differentiation pathway that leads to invasion of the uterine wall. In vitro, CTBs emulate in vivo cell behaviors, such as migration, aggregation and substrate penetration. While some of the molecular features related to these cell behaviors have been described, the underlying mechanisms, at a global level, remain undefined at mid-gestation...

With increased life expectancy, women will spend over three decades of life post-menopause. The menopausal transition increases susceptibility to metabolic diseases such as obesity, diabetes, cardiovascular disease, and cancer. Thus, it is more important than ever to develop effective hormonal treatment strategies to protect aging women. Understanding the role of estrogens, and their biological actions mediated by estrogen receptors (ERs), in the regulation of cardiometabolic health is of paramount importance to discover novel targeted therapeutics...

Lawsonia intracellularis is an obligate intracellular bacterial pathogen that causes proliferative enteropathy (PE) in pigs. L. intracellularis infection causes extensive intestinal crypt cell proliferation and inhibits secretory and absorptive cell differentiation. However, the affected host upstream cellular pathways leading to PE are still unknown. β-catenin/Wnt signalling is essential in maintaining intestinal stem cell (ISC) proliferation and self-renewal capacity, while Notch signalling governs differentiation of secretory and absorptive lineage specification...

For a company to provide high value to its customers, its organization design is critical. As health care transitions to a value-based model, it is critical that spinal care organizations are structured in such a way that they can maximize value to both the patient and the payers. This article will discuss the 3 most common ways that an organization can be structured, and the benefits and problems of each design in spinal care.
