Periauricular paresthesia may afflict patients for a significant amount of time after facelift surgery. When performing face and neck lift surgery, temple and posterior auricular flap dissection is undertaken directly over the auriculotemporal, great auricular, and lesser occipital nerve territory, leading to potential damage to the nerve. The auriculotemporal nerve remains under the thin outer superficial fascia just below the subfollicular level in the prehelical area. To prevent damage to the auriculotemporal nerve and to protect the temporal hair follicle, the dissection plane should be kept just above the thin fascia covering the auriculotemporal nerve...

OBJECTIVES: Intra-abdominal pressure (IAP) may contribute to pelvic floor health, although the direction and magnitude of such an effect, if any, are not yet known. Identifying individual characteristics, and in particular modifiable factors, associated with higher IAP during recovery from vaginal childbirth might serve to mitigate early pelvic floor dysfunction. The aim of this study was to identify characteristics associated with maximal IAP during lifting in postpartum primiparous women who delivered vaginally...

Inorganic amorphous oxide semiconductor (AOS) materials such as amorphous InGaZnO (a-IGZO) possess mechanical flexibility and outstanding electrical properties, and have generated great interest for use in flexible and transparent electronic devices. In the past, however, AOS devices required higher activation energies, and hence higher processing temperatures, than organic ones to neutralize defects. It is well known that one-dimensional nanowires tend to have better carrier mobility and mechanical strength along with fewer defects than the corresponding two-dimensional films, but until now it has been difficult, costly, and impractical to fabricate such nanowires in proper alignments by either "bottom-up" growth techniques or by "top-down" e-beam lithography...

PURPOSE OF REVIEW: A common concern regarding pelvic floor surgery is the relatively high risk of recurrence. In an effort to minimize this risk, many surgeons instruct their patients to avoid certain activities during the healing process so as not to damage the repair before proper healing has occurred. However, many of these restrictions have been historically based on little to no hard evidence. The purpose of this review is to present the latest evidence-based recommendations regarding restrictions and limitations after pelvic floor surgery...

Common estimates of external training intensity for resistance exercise do not incorporate inter-set recovery duration, and might not reflect the overall demands of training. This study aimed to assess novel metrics of exercise density (ED) during resistance exercise, and how these related to a physiological marker of internal training intensity as well as traditional measures of external training intensity and volume. Thirteen males and seven females performed two bouts of resistance exercise focused on developing strength (5 sets of 5 repetitions with 5-repetition maximum; 180 s recovery) and hypertrophy (3 sets of 10 repetitions with 10-repetition maximum; 60 s recovery)...

BACKGROUND: The sinus lift (or sinus augmentation) is a common procedure to improve maxillary bone stock before dental implantation. Chronic rhinosinusitis (CRS) is a potential complication of this procedure and may be refractory to medical treatment. Functional endoscopic sinus surgery has previously been used to address CRS, however, results of previous studies indicated that implant removal is required. There are limited follow-up data available. OBJECTIVE: The purpose of this study was to characterize the long-term outcomes and efficacy of endoscopic sinus surgery for refractory CRS after sinus lift, including the ability to salvage dental implants...

Yiyun Lan, Jun Yao, Julius P A Dewald
Application of neural machine interface in individuals with chronic hemiparetic stroke is regarded as a great challenge, especially for classification of the hand opening and grasping during a functional upper extremity movement such as reach-to-grasp. The overall accuracy of classifying hand movements, while actively lifting the paretic arm, is subject to a significant reduction compared to the accuracy when the arm is fully supported. Such a reduction is believed to be due to the expression of flexion synergy, which couples shoulder abduction (SABD) with elbow/wrist and finger flexion, and is common in up to 60% of the stroke population...

There is limited information in the literature related to the lower back loading in patients with LBP, particularly those with non-chronic LBP. Toward addressing such a research gap, a case-control study was conducted to explore the differences in lower back mechanical loads between a group of females (n=19) with non-chronic, non-specific LBP and a group of asymptomatic females (n=19). The differences in lower back mechanical loads were determined when participants completed one symmetric lowering and lifting of a 4...

REVIEW
Jonas Franz, Marco Tarantola, Christoph Riethmüller
Tetraspanins are ubiquitous membrane proteins that induce local membrane curvature and hence co-ordinate cell-to-cell contacts. This review highlights their role in inflammation, which requires control of the nano-architecture of attachment sites between endothelial cells and leukocytes. The active role of endothelial cells in preparing for transmigration of leukocytes and determining the severity of an inflammation is often underscored. A clear hint to endothelial pre-activation is their ability to protrude clustered adhesion proteins upward prior to leukocyte contact...

M Yasinul Karim, Eric I Corwin
We experimentally study quasi-two-dimensional dilute granular flow around intruders whose shape, size, and relative impact speed are systematically varied. Direct measurement of the flow field reveals that three in-principle independent measurements of the nonuniformity of the flow field are in fact all linearly related: (1) granular temperature, (2) flow-field divergence, and (3) shear-strain rate. The shock front is defined as the local maxima in each of these measurements. The shape of the shock front is well described by an inverted catenary and is driven by the formation of a dynamic arch during steady flow...

The two-dimensional and time-periodic wake flows produced by a pitching foil are investigated numerically for a fixed flapping amplitude. As the flapping frequency is increased, three regimes are identified in the time-marching nonlinear simulations. The first regime is characterized by nondeviated wake flows with zero time-averaged lift. In the second regime, the wake flow is slightly deviated from the streamwise direction and the time-averaged lift is slightly positive or negative. The third regime is characterized by larger deviations of the wake, associated with larger values of both the time-averaged lift and the thrust...

Primary C-fiber nociceptors are broadly divided into peptidergic and non-peptidergic afferents. TRPV1 is a thermosensitive cation channel mainly localized in peptidergic nociceptors whereas MrgD is a sensory G protein-coupled receptor expressed in most non-peptidergic nociceptive afferents. TRPV1 and MrgD fibers have been reported to be primarily involved in thermal and mechanical nociception, respectively. Yet, their functional assessment in somatosensory transmission relied on ablation strategies that do not account for compensatory mechanisms...

An automatic detection system for distinguishing normal, ictal, and interictal electroencephalogram (EEG) signals is of great help in clinical practice. This paper presents a three-class classification system based on discrete wavelet transform (DWT) and the nonlinear sparse extreme learning machine (SELM) for epilepsy and epileptic seizure detection. Three-level lifting DWT using Daubechies order 4 wavelet is introduced to decompose EEG signals into delta, theta, alpha, and beta subbands. Considering classification accuracy and computational complexity, the maximum and standard deviation values of each subband are computed to create an eight-dimensional feature vector...

Hammerhead sharks (Sphyrnidae) are have a large amount of morpholigcal variation within the family, making them the focus of many studies. The size of the laterally expanded head, or cephalofoil, is inversely correlated with pectoral fin area. The inverse relation in cephalofoil and pectoral fin size in this family suggests that they might serve a complimentary role in lift generation. The cephalofoil is also hypothesized to increase olfaction, electroreception, and vision; however, little is known about how morphological variation impacts post-cranial swimming kinematics...

Musculoskeletal injuries, especially back injuries, are among the most frequent injuries sustained by direct caregivers who lift, transfer, and reposition patients. These injuries can be debilitating and, for some caregivers, career ending. In the first year following implementation of the safe patient handling program in a multihospital health care system, an 82% reduction in Occupational Health and Safety Administration (OSHA) recordable patient handling injuries was realized, a 94% decrease in days away from work, an 85% reduction in restricted duty days, and an 82% reduction in incurred workers' compensation costs...
