Shifting sands: How parents engage with the idea of their child's death.

OBJECTIVES.: While parental prognostic awareness is a vital concept, its complexity can sometimes be underestimated. Our study aimed to understand how parents of children with serious illness engage with the idea of their child's death from a lived experience perspective. METHODS.: Bereaved parents of children known to a statewide pediatric palliative care service, who died at the age of 16 years or younger from any medical condition, participated in semi-structured interviews. Reflexive thematic analysis was employed, informed by a phenomenological framework. RESULTS.: Twenty bereaved paren

Experimental study on the homogeneity of microbial grouting to reinforce calcareous sand.

Microbial-induced calcium carbonate precipitation (MICP) technology has shown remarkable potential in environmental engineering fields, such as soil improvement, pollution control and hydrological barrier construction. However, when applied to the reinforcement of sandy materials, the main challenge of MICP technology is the nonuniformity of the curing effect, which greatly restricts the application of this technology in practical engineering. The aim of this study is to explore and optimise the application of MICP technology in calcareous sand reinforcement to improve the uniformity and effic…

Are toe fringes important for lizard burying in highly mobile sand?

Toe fringes are a key innovation for sand dwelling lizards, and the relationship between toe fringe function and substrate properties is helpful in understanding the adaptation of lizards to sand dune environments. We tested the sand burial performance of Phrynocephalus mystaceus on different sand substrates with toe fringe manipulation, with the aim of assessing whether the function of the toe fringes shifts under different substrate properties, especially in highly mobile substrates. The sand burial performance of P. mystaceus was influenced by substrate properties in relation to the toe fri…

Hansen's disease (also known as leprosy) is a chronic infection that is caused by Mycobacterium leprae. It predominantly affects the periphe … two Japanese films, namely Kojimanoharu (no English title; "Spring in Islets") (1940) and Casle of Sand (1974), inspired by these events and addressing the concerns regarding this disease, are discussed.

Sand Flies and Pathogens in the Lowlands of Emilia-Romagna (Northern Italy).

Cases of sand fly-borne diseases in the Emilia-Romagna region, such as meningitis caused by Toscana virus and human leishmaniasis, are reported annually through dedicated surveillance systems. Sand flies are abundant in the hilly part of the region, while the lowland is unsuitable habitat for sand flies, which are found in lower numbers in this environment with respect to the hilly areas. In this study, we retrieved sand flies collected during entomological surveillance of the West Nile virus (from 2018 to 2021) to assess their abundance and screen them for the presence of pathogens. Over the …

A Novel Sand Dollar and Staves Technique for Unilateral Lambdoid Craniosynostosis.

BACKGROUND: Unilateral lambdoid synostosis (ULS) is the rarest form of craniosynostosis. Due to the associated cranio-caudal shift seen in ULS, surgical correction is technically challenging from a morphological standpoint. Herein, the authors present a novel "Sand-Dollar and Staves" technique for the repair of ULS. METHODS: A zigzag coronal incision is performed, and an anteriorly-based pericranial flaps are elevated. Prefabricated cutting guides are placed and the calvarium is marked. To treat the flattening on the ipsilateral side, a wedged suturectomy is performed with additional barrel s…

The Diversity of Yellow-Related Proteins in Sand Flies (Diptera: Psychodidae).

Yellow-related proteins (YRPs) present in sand fly saliva act as affinity binders of bioamines, and help the fly to complete a bloodmeal by scavenging the physiological signals of damaged cells. They are also the main antigens in sand fly saliva and their recombinant form is used as a marker of host exposure to sand flies. Moreover, several salivary proteins and plasmids coding these proteins induce strong immune response in hosts bitten by sand flies and are being used to design protecting vaccines against Leishmania parasites. In this study, thirty two 3D models of different yellow-related p…

Acid deposition in the Athabasca Oil Sands Region: a policy perspective.

Industrial emissions of sulphur (S) and nitrogen (N) to the atmosphere associated with the oil sands industry in north-eastern Alberta are of interest as they represent the largest localized source in Canada (with potential for future growth) and the region features acid-sensitive upland terrain. Existing emission management policy for the Regional Municipality of Wood Buffalo, where the industry is located, is based on a time-to-effect approach that relies on dynamic model simulations of temporal changes in chemistry and features highly protective chemical criteria. In practice, the policy is…

Unusual presentation of sand aspiration in a 14-mo-old child.

Accidental sand aspiration is an unusual but potentially life-threatening condition in children. Sand aspiration often occurs in cases of near drowning and accidental burial in sand. The authors report a case of accidental sand aspiration in a 14-mo-old girl while she was playing with sand. Though child was symptomatic and chest radiograph was showing obstructive emphysema initially, there was spontaneous resolution of radiographic findings and clinical condition within 48 h. Child was treated conservatively and was discharged. Follow up examination after 2 mo revealed persistent wheeze but no…

The structure of the female sand fly (Phlebotomus papatasi) alimentary canal.

In the sand fly vector, Leishmania parasites are confined to the alimentary canal. During much of their development, promastigotes are attached to the wall of the gut via their flagella. In this context, the surface of the different regions of the sand fly alimentary tract lumen warrants scientific attention. In this paper, the various regions are described, for the first time using scanning electron microscopy. The cibarium and the pharynx, which function as pumping organs, are lined with cuticle. Parts of the cibarium and the pharynx bear different types of cuticular spines and appendages. T…

Transmission of cutaneous leishmaniasis by sand flies is enhanced by regurgitation of fPPG.

Sand flies are the exclusive vectors of the protozoan parasite Leishmania, but the mechanism of transmission by fly bite has not been determined nor incorporated into experimental models of infection. In sand flies with mature Leishmania infections the anterior midgut is blocked by a gel of parasite origin, the promastigote secretory gel. Here we analyse the inocula from Leishmania mexicana-infected Lutzomyia longipalpis sand flies. Analysis revealed the size of the infectious dose, the underlying mechanism of parasite delivery by regurgitation, and the novel contribution made to infection by …

Further observations on pineal brain sand formation and evolution in man.

Acervuli obtained from fragments of the human pineal glands of subjects of both sexes and age ranging from 23 to 87 years were analyzed by light microscopy after histochemical stains and by EDS-microanalysis. It was found that the sub-units and acervuli are positive to P.A.S., Alcian Blue pH 2.5, Gomori-Bargmann procedures for the presence of proteins, glycoproteins, proteoglycans and of the neurosecretory material in different layers of the sub-units and acervuli. We suppose that the increase of Mg++ in the sub-unit from the core to the periphery is responsible for the inhibition of following

Histologic and morphometric observations on vertebral bone of aging sand rats.

The trabecular bone of the vertebrae of 30 male and 30 female sand rats (Psammomys obesus) aged 13 to 33 months was examined histologically and morphometrically. The usual age-linked decline of bone mass failed to occur in females and was statistically not significant in males. A few changes with age were noted at the cellular level. Sex differences were statistically significant only in animals living into the third year of life, males having a smaller bone mass than females. This abnormality of the vertebral spongiosa is attributed to pathologic local stresses caused by the numerous instance…
