Videos of Surgery Used to Teach Robot to Suture
Surgery has a reputation as being an intellectual profession, but a lot of the actual practice of surgery involves simple, routine tasks that are performed on nearly every patient. Suturing is one of those and a team of researchers from University of California Berkley and Intel thinks that it is possible to teach a robot to suture by having it learn from videos of suturing performed by real surgeons. This may one day allow human surgeons to focus on their core tasks while letting robots do the monotonous...

Genome‐wide association study identifies CDH13 as a susceptibility gene for rhododendrol‐induced leukoderma
Abstract Racemic RS‐4‐(4‐hydroxyphenyl)‐2‐butanol (rhododendrol; trade name: Rhododenol [RD]), which is used in topical skin‐lightening cosmetics, was unexpectedly reported in Japan to induce leukoderma or vitiligo called RD‐induced leukoderma (RIL) after repeated application. To our knowledge, no studies have investigated chemical‐induced vitiligo pathogenesis on a genome‐wide scale. Here, we conducted a genome‐wide association study (GWAS) for 147 cases and 112 controls. CDH13 , encoding a GPI‐anchored...

Donskoy cats as a new model of oculocutaneous albinism with the identification of a splice‐site variant in Hermansky‐Pudlak Syndrome 5 gene
Abstract In the feline Donskoy breed, a phenotype that breeders call "pink‐eye", with associated light‐brown skin, yellow irises and red‐eye effect, has been described. Genealogical data indicated an autosomal recessive inheritance pattern. A single candidate region was identified by genome‐wide association study and SNP‐based homozygosity mapping. Within that region, we further identified HPS5 (HPS5 Biogenesis Of Lysosomal Organelles Complex 2 Subunit 2 ) as a strong candidate gene, since HPS5...

Ethmoid‐to‐maxillary opacification ratio: a predictor of postoperative olfaction and outcomes in nasal polyposis?
Background Inflammatory profiles for patients with chronic rhinosinusitis with nasal polyposis (CRSwNP) vary between North American and Asian populations. An elevated ethmoid‐to‐maxillary (E/M) opacification ratio on preoperative imaging is associated with certain postoperative outcomes in Asian populations and populations that are non‒type 2 dominant. In this study we explore this factor in North American/type 2‒based populations. Methods Adult patients (n = 165) from a North American population...

Assessing the reliability of virtual reconstruction of mandibles
Abstract Objectives Mandibular morphological variation is often used to examine various aspects of human palaeobiology. However, fossil and archeological skeletal remains are often fragmented/distorted and so are frequently excluded from studies. This leads to decreased sample sizes and, potentially, to biased results. Thus, it is of interest to restore the original anatomy of incomplete/distorted specimens. Thin plate splines (TPS), commonly used in Geometric Morphometrics (GM), offer the prospect...

Vemurafenib‐related photosensitivity
Summary Increased photosensitivity is a common cutaneous adverse effect associated with the BRAF inhibitor vemurafenib. Clinically, it presents as an immediate sensation of heat and edematous erythema during sun exposure, as well as a sunburn reaction in terms of a late reaction. Phototesting has shown that the UVA range (320 nm to 400 nm), for both the immediate and the late reaction. In terms of pathogenesis, photochemical studies have suggested that exposure of vemurafenib to UVA radiation produces...

A daytime nap does not increase mnemonic discrimination ability
Abstract It has been proposed that sleep readies the brain for novel learning, and previous work has shown that sleep loss impairs the ability to encode new memories. In the present study, we examined if a daytime nap would increase mnemonic discrimination (MD) performance. MD is the ability to differentiate between memories that are similar but not identical. Participants performed the Mnemonic Similarity Task (MST) twice, once in the morning and once in the afternoon. The goal of this task is...

Acceptance of virtual agents in a homecare context: Evaluation of excessive daytime sleepiness in apneic patients during interventions by continuous positive airway pressure (CPAP) providers
Abstract Sleep apnea syndrome treatment relies primarily on continuous positive airway pressure, which requires a homecare follow‐up. Excessive daytime sleepiness is a key symptom to be measured during follow‐up, and there is a need for more easy‐to‐administer, ecological and engaging tools to assess it. Virtual agents have shown their effectiveness in performing clinical evaluation in a medical environment. A virtual agent assessing excessive daytime sleepiness via the Epworth Sleepiness Scale...

Comparison of the effect of weight change, simulated computational continuous positive airway pressure treatment and positional therapy on severity of sleep apnea
Abstract Weight loss, continuous positive airway pressure (CPAP) and positional therapy (PT) are important treatments in obstructive sleep apnea (OSA). Although all of these reduce the apnea–hypopnea index (AHI) effectively, the benefits of these treatments have not been thoroughly investigated in a patient‐specific manner. Therefore, clinicians do not have objective means to choose an optimal treatment for each patient. We aim to provide clinicians the possibility for treatment optimization in...

The loss of self‐incompatibility in a range expansion
Abstract It is commonly observed that plant species’ range margins are enriched for increased selfing rates and, in otherwise self‐incompatible species, for self‐compatibility (SC). This has often been attributed to a response to selection under mate and/or pollinator limitation. However, range expansion can also cause reduced inbreeding depression, and this could facilitate the evolution of selfing in the absence of mate or pollinator limitation. Here, we explore this idea using spatially explicit...

Digitization of the Nissen–Riesen chimpanzee radiological growth series
Abstract Longitudinal morphological growth data of apes are incredibly difficult to obtain. Long life histories, combined with practical and ethical issues of obtaining such long‐term data have resulted in few longitudinal data sets in chimpanzees of known chronological ages. One classic, long‐term growth study of chimpanzees was that of Drs Nissen and Riesen initiated at the Yale Laboratories of Primate Biology in 1939. Through that study, whole‐body radiological images were taken on a regular...
