Diaci v3.0: chromosome-level assembly, de novo transcriptome, and manual annotation of Diaphorina citri, insect vector of Huanglongbing.

Background: Diaphorina citri is an insect vector of "Candidatus Liberibacter asiaticus" (CLas), the gram-negative bacterial pathogen associated with citrus greening disease. Control measures rely on pesticides with negative impacts on the environment, natural ecosystems, and human and animal health. In contrast, gene-targeting methods have the potential to specifically target the vector species and/or reduce pathogen transmission.

Annotation of putative circadian rhythm-associated genes in (Hemiptera: Liviidae).

The circadian rhythm involves multiple genes that generate an internal molecular clock, allowing organisms to anticipate environmental conditions produced by the Earth's rotation on its axis. Here, we present the results of the manual curation of 27 genes that are associated with circadian rhythm in the genome of the Asian citrus psyllid. This insect is the vector for the bacterial pathogen Liberibacter asiaticus (Las), the causal agent of citrus greening disease (Huanglongbing).

An unusual inherited electroretinogram feature with an exaggerated negative component in dogs.

Objectives: To assess an inherited abnormal negative response electroretinogram (NRE) that originated in a family of Papillon dogs.

Animals Studied: Thirty-eight dogs (Papillons, or Papillon cross Beagles or Beagles).

Procedures: Dogs underwent routine ophthalmic examination and a detailed dark-adapted, light-adapted and On-Off electroretinographic study.

Captive rearing of orphaned African wild dogs (Lycaon pictus) in Namibia: A case study.

African wild dogs (AWDs; Lycaon pictus) are an endangered canid species facing drastic decline throughout their range due to habitat fragmentation and persecution by humans over livestock depredation, resulting in dens destroyed and adult members of packs and pups often being killed. Breeding of captive AWDs is challenging due to high juvenile mortality, only marginally improved from wild conditions, thus both in situ and ex situ conservation remains critical. As a result of human-wildlife conflict, between 2017 and 2018, the Namibian Ministry of Environment, Forestry and Tourism confiscated three litters of orphaned AWD pups from rural farmers who had destroyed the dens in Eastern Namibia and placed the pups with the Cheetah Conservation Fund.

Using conjoint analysis to measure the importance of psychosocial traits in the choices of bladder management after spinal cord injury.

Objective: To conduct a conjoint analysis experiment to better understand the psychosocial priorities related to bladder management in individuals after spinal cord injury (SCI).

Methods: We developed a conjoint analysis survey that included 11 psychosocial attributes phrased in the context of bladder management (including attributes for urinary infections, and incontinence). We then performed a multi-center prospective cross-sectional study of adults with existing SCI which consisted of a baseline interview, followed by the online conjoint analysis survey (delivered through Sawtooth software).

Biochemical properties, nutritional values, health benefits and sustainability of palm oil.

Palm oil (PO), although subject of controversies, is the most consumed oil and the first source of oil widely produced. In this review, we discussed its biochemical composition in fatty acids, carotenoids, vitamin E, its phenolic compounds, and its nutritional benefits. We addressed its biochemical properties in relation with the stereospecific distribution of its unsaturated fatty acids at the sn-2 position in triacylglycerols.

A qualitative assessment of psychosocial aspects that play a role in bladder management after spinal cord injury.

Study Design: Prospective qualitative study using semi-structured, open-ended interviews.

Objectives: To better understand psychosocial aspects of bladder management after spinal cord injury (SCI).

Setting: People with SCI, recruited through three tertiary care centres in North America.

Phenotypic characterization of complete CSNB in the inbred research beagle: how common is CSNB in research and companion dogs?

Purpose: Although congenital stationary night blindness (CSNB) has been described in a Japanese beagle dog research colony, certain clinical correlates with human CSNB have not yet been described, nor has an estimate of frequency of the condition been made in inbred and outbred beagle populations.

Methods: A beagle with CSNB obtained from a commercial research dog supplier in the USA and matched control dogs (n = 3) underwent examination, refraction, ocular imaging, assessment of visual navigation ability and detailed electroretinography (ERG). Retrospective review of ERGs in two independent groups of inbred (n = 15 and 537, respectively) and one group of outbred dogs (n = 36) was used to estimate CSNB frequency in these populations.

Gene Therapy in a Large Animal Model of PDE6A-Retinitis Pigmentosa.

Despite mutations in the rod phosphodiesterase 6-alpha () gene being well-recognized as a cause of human retinitis pigmentosa, no definitive treatments have been developed to treat this blinding disease. We performed a trial of retinal gene augmentation in the mutant dog using delivery by capsid-mutant adeno-associated virus serotype 8, previously shown to have a rapid onset of transgene expression in the canine retina. Subretinal injections were performed in 10 dogs at 29-44 days of age, and electroretinography and vision testing were performed to assess functional outcome.

Early-Onset Progressive Degeneration of the Area Centralis in RPE65-Deficient Dogs.

Purpose: Retinal epithelium-specific protein 65 kDa (RPE65)-deficient dogs are a valuable large animal model species that have been used to refine gene augmentation therapy for Leber congenital amaurosis type-2 (LCA2). Previous studies have suggested that retinal degeneration in the dog model is slower than that observed in humans. However, the area centralis of the dog retina is a cone and rod photoreceptor rich region comparable to the human macula, and the effect of RPE65 deficiency specifically on this retinal region, important for high acuity vision, has not previously been reported.

Acute primary canine herpesvirus-1 dendritic ulcerative keratitis in an adult dog.

We present a report of dendritic ulcerative keratitis in a 4-year old locally immunosuppressed dog suspected to result from acute primary canine herpesvirus-1 (CHV-1) infection. The dog was presented for evaluation of mild blepharospasm and conjunctival hyperemia in the right eye (OD) shortly after attending a public boarding facility. For approximately 3 months, the dog had been receiving topical prednisolone acetate 1.

Attending to social vulnerability when rationing pandemic resources.

Pandemic plans are increasingly attending to groups experiencing health disparities and other social vulnerabilities. Although some pandemic guidance is silent on the issue, guidance that attends to socially vulnerable groups ranges widely, some procedural (often calling for public engagement), and some substantive. Public engagement objectives vary from merely educational to seeking reflective input into the ethical commitments that should guide pandemic planning and response.

Environmental enrichment delays pup-induced maternal behavior in rats.

Adult, virgin rats do not spontaneously display maternal behavior when exposed to foster pups. However, continuous daily exposure of the female to foster pups for about 5-7 days can induce a set of maternal behaviors similar to those shown by postpartum dams. Induction latencies depend upon a number of factors, including the stress and anxiety levels of the female.

Ethical considerations in pandemic influenza planning.

Although the timing and severity of the next influenza pandemic is impossible to predict, there is broad agreement that one will occur. Preparation is vital to mitigating its effects. A severe influenza pandemic like that which began in 1918 would be unlike other disasters in nature, scale, and duration.

Allocating pandemic influenza vaccines in Minnesota: recommendations of the Pandemic Influenza Ethics Work Group.

A public-private, multidisciplinary work group developed recommendations for rationing vaccines in Minnesota during a worst-case influenza pandemic. The recommendations encompass an ethical framework of principles, goals, and strategies. The primary goal is to maximize Minnesotans' chances of surviving both the pandemic and the years immediately thereafter and to limit two major causes of death: (a) influenza and complications of influenza, and (b) disruption of basic health care, public health, and public safety infrastructures.

Studying neurosurgical implants for Parkinson disease: a question of design.

North American researchers' perspectives on designing neurosurgical implant studies for Parkinson disease (PD) challenged the custom of holding surgical trials to less stringent evidentiary standards than other clinical studies. Researchers supported placebo surgery-controlled trials. The framework they used to design and evaluate studies both of deep brain stimulation and cellular implants for PD may be applicable to a broad range of surgical implants for other disorders.

A model for improving coverage policy decisions.

Reasoned and defensible coverage decisions are essential for a fairer and more efficient healthcare system. Because healthcare resources are finite, coverage decisions should be informed by economic evaluations and made from a perspective that attends to the interests of both individuals and the population enrolled in a plan as a whole. Coverage decisions for all healthcare interventions should follow a 2-step procedure that consists of (1) the relatively impartial and objective assessment of an intervention's eligibility for coverage and (2) the distinctively value-laden determination (for which the enrolled population's values and preferences should take priority) to cover, conditionally cover, or not cover an intervention.
