The deposition of reactive nitrogen (N) compounds currently predominates over sulphur (S) deposition in most of the cities in Europe and North America. Acidophytic lichens growing on tree trunks are known to be sensitive to both N and S deposition. Given that tree species and climatic factors affect the composition of epiphytic lichen communities and modify lichen responses to air pollution, this study focused on the impact of urban air pollution on acidophytes growing on boreal conifer trunks. The study was performed in the Helsinki metropolitan area, southern Finland, where annual mean nitrogen dioxide (NO2) concentrations range from 4-5μgm(-3) to >50μgm(-3)...

Vascular anomalies can occur anywhere in the body, and the majority present in the pediatric population. Accurate classification is essential for proper clinical evaluation, particularly because multidisciplinary care is often required. The International Society for the Study of Vascular Anomalies classification offers a comprehensive classification for all subspecialties. In this review article, we present a magnetic resonance imaging protocol with exemplary cases of the most common types of vascular anomalies in the pediatric trunk and extremities using the current International Society for the Study of Vascular Anomalies classification...

Phacomatosis pigmentokeratotica is a recently identified disease characterized by the coexistence of an epidermal nevus with sebaceous differentiation arranged along Blaschko lines and a speckled lentiginous nevus showing a checkerboard pattern, mostly in association with various extracutaneous defects. A 52-year-old man presented with asymptomatic ulcerative plaque on his left side of perioral area. A 2 × 2-cm-sized fleshy colored ulceration on his left perioral area was consistent with basal cell carcinoma with nevus sebaceous...

Pulmonary embolism (PE) refers to the endogenous or exogenous emboli blocking pulmonary trunk or branches, causing clinical and pathophysiological syndrome of pulmonary circulation disorder, the incidence rate is high. Sometimes PE patients were lack of specific symptoms and signs, or without any symptoms, which often result in misdiagnosis, un-timely diagnosis, and the delay of treatment. A PE case with syncope, vomiting and shock, which was proved to be pulmonary artery trunk and branch wide embolism later, was presented so as to improve the understanding of the disease...

The provision of an appropriate wheelchair, one that provides proper fit and postural support, promotes wheelchair users' physical health and quality of life. Many wheelchair users have postural difficulties, requiring supplemental postural support devices for added trunk support. However, in many low- and middle-income settings, postural support devices are inaccessible, inappropriate or unaffordable. This article describes the use of the design challenge model, informed by a design thinking approach, to catalyse the development of an affordable, simple and robust postural support device for low- and middle-income countries...

Ectothermal reptiles have internal pigmentation, which is not seen in endothermal birds and mammals. Here we show that the development of the dorsal neural tube-derived melanoblasts in turtle Trachemys scripta is regulated by similar mechanisms as in other amniotes, but significantly later in development, during the second phase of turtle trunk neural crest emigration. The development of melanoblasts coincided with a morphological change in the dorsal neural tube between stages mature G15 and G16. The melanoblasts delaminated and gathered in the carapacial staging area above the neural tube at G16, and differentiated into pigment-forming melanocytes during in vitro culture...

The Drosophila body comprises a central part, the trunk, and outgrowths of the trunk, the appendages. Much is known about appendage regeneration, but little about the trunk. As the wing imaginal disc contains a trunk component, the notum, and a wing appendage, we have investigated the response to ablation of these two components. We find that in contrast with the strong regenerative response of the wing, the notum does not regenerate. Nevertheless, the elimination of the wing primordium elicits a proliferative response of notum cells, but they do not regenerate wing; they form a notum duplicate...

Neuromuscular electrical stimulation (NMES) is used to produce contractions to restore movement and reduce secondary complications for individuals experiencing motor impairment. NMES is conventionally delivered through a single pair of electrodes over a muscle belly or nerve trunk using short pulse durations and frequencies between 20-40 Hz (conventional NMES). Unfortunately, the benefits and widespread use of conventional NMES are limited by contraction fatigability, which is due in large part to the non-physiological way that contractions are generated...

Subcutaneous fat necrosis of the newborn (SFNN) is a rare disorder characterised by indurated plaques or nodules with or without erythema, typically distributed over the cheeks, extremities, posterior trunk, buttocks, and thighs, and appears during the first 2 weeks of life. It is commonly associated with perinatal asphyxia and, while usually self-limited, can lead to severe hypercalcemia. There is no known familial association. The present article describes a neonate with extensive disease, counterintuitive hypocalcemia, and a family history of SFNN and reviews the existing literature on SFNN...

[Purpose] Seated side tapping test (SST) performance is associated with mobility impairment in the elderly. Although this test was developed to assess trunk function, interpretation of its results may be confounded by the upper-limb movements in its protocol. Here, this study aimed to validate the association between trunk function and gait function by means of the Arms Crossed SST (AC-SST), a modified version of the SST in which the arms are crossed over the chest, to exclude the effects of the upper limbs...

BACKGROUND: When an excision is performed by a method other than elliptical excision, direct primary wound closure can result in standing cones or "dog-ears." In 2008, Lee and colleagues noted that dog-ears of <8 mm in height have a statistically greater tendency to resolve without further surgical correction than larger dog-ears. OBJECTIVE: To stratify dog-ears by anatomic location and inform on the need for correction at the time of surgery. MATERIALS AND METHODS: After tumor extirpation, patients were counseled that primary closure of the surgical wound would result in dog-ears at the wound apices...
