Recombinant live-attenuated chimeric tetravalent dengue vaccine viruses, TDV-1, -2, -3, and -4, contain the premembrane and envelope genes of dengue virus serotypes 1-4 in the replicative background of the attenuated dengue virus type-2 (DENV-2) PDK-53 vaccine strain. Previous results have shown that these recombinant vaccine viruses demonstrate limited infection and dissemination in Aedes aegypti and are unlikely to be transmitted by the primary mosquito vector of DENVs. In this report, we expand this analysis by assessing vector competence of all four serotypes of the TDV virus in Aedes albopictus, the secondary mosquito vector of DENVs...

Persistent embryonic veins represent a major source of venous hypertension and morbidity in venous malformation syndromes, such as Klippel-Trénaunay syndrome and congenital lipomatous overgrowth, vascular malformations, epidermal nevus, and skeletal deformities syndrome. Surgical stripping and phlebectomy are the most commonly reported alternatives to compression therapy for refractory cases. These techniques, although effective in those patients who meet the necessary anatomic criteria, can be associated with bleeding, wound-related complications, and recurrence...

Genetic vaccines based on replication-incompetent adenoviral (AdV) vectors are currently in clinical development. Monovalent AdV vectors express one antigen from an expression cassette placed in most cases in the E1 region. For many vaccines, inclusion of several antigens is necessary in order to raise protective immunity and/or target more than one pathogen or pathogen strain. Based on the current technology, a mix of several monovalent vectors can be employed. However, a mix of the standard monovalent AdV may not be optimal with respect to manufacturing costs and the final dose per vector in humans...

In Italy, Law n. 24 of 8 March 2017, Article 6, introduces in the current criminal code, Article 590 sexies entitled "Medical liability in case of death and personal lesions", which follows article 590 quinquies. The new article states that a healthcare professional who has acted in accordance with guidelines approved by the National Health Institute or, if no such guidelines exist, in accordance with good clinical practices, is not criminally liable in case of death or personal lesions due to actions that could be considered to be incompetent...

Whereas role-playing and table-top role-play games (RPGs) have been proven to have potential as therapeutic tools, playing RPGs is often stereotypically associated with social incompetence and psychiatric disorders. Knowledge regarding the stereotype and its implications is very scarce specifically among mental health practitioners. Therefore the present study aimed to narrow this gap in knowledge by examining the perception of Social Workers that are considered to be the forefront of mental health-care, in regard to the association between playing RPGs and mental health...

PURPOSE: To define the role of the dorsal capsule and associated dorsal fibrocartilage (DFC) and their interactions with the radial collateral ligament (RCL) as a thumb metacarpophalangeal (MCP) joint stabilizer. METHODS: Eight cadaveric thumbs were mounted onto a custom jig with 20 N of muscle load applied. The thumb position in space was digitized to measure ulnar-radial, pronation-supination, and volar-dorsal laxity at 0°, 30°, and 60° MCP joint flexion. Serial sectioning was performed and measurements were repeated for the intact state, proper RCL insufficiency, proper and accessory (complete) RCL insufficiency, complete RCL with 50% DFC (radial) insufficiency, and complete RCL with complete DFC insufficiency...

Dinitrogen (N2)-fixation by cyanobacteria in symbiosis with feathermosses is the primary pathway of biological nitrogen (N) input into boreal forests. Despite its significance, little is known about the cyanobacterial gene repertoire and regulatory rewiring needed for the establishment and maintenance of the symbiosis. To determine gene acquisitions and regulatory changes allowing cyanobacteria to form and maintain this symbiosis, we compared genomically closely related symbiotic-competent and -incompetent Nostoc strains using a proteogenomics approach and an experimental set up allowing for controlled chemical and physical contact between partners...

Urethral sphincter mechanism incompetence (USMI) is reported much more seldom in male dogs than in female dogs. The few existing reports evaluating the efficacy of medical therapy in controlling USMI in males have demonstrated limited success. In this case series, we report the effect of testosterone cypionate, given at a median dose of 1.5 mg/kg intramuscularly every 4 wk, in eight male dogs with USMI. Response was evaluated through the review of medical records and telephone interviews with the clients. Based on owners' assessments, a good to excellent response was reported in three of eight dogs (38%), a slight response was reported in one of eight dogs (12%), and a poor response was reported in four of eight dogs (50%)...

Primary empty sella (PES) is characterized by the herniation of the subarachnoid space within the sella, which is often associated with variable degree of flattening of the pituitary gland in patients without previous pituitary pathologies. PES pathogenetic mechanism are not well known but seem due to a sellar diaphragm incompetence, associated to the occurrence of upper sellar or pituitary factors, as intracranial hypertension and change of pituitary volume. As PES represents in majority of cases a neuroradiological findings, without any clinical implication, the occurrence of endocrine, neurological and opthalmological symptoms, due to the above describes anatomical alteration, delineates the so called PES syndrome...

There is accumulating evidence that interactions between epidermal melanocytes and stromal cells play an important role in the regulation of skin pigmentation. In this study we established a pigmented dermo-epidermal skin model (melDESS) of human origin to investigate the effects of distinct stromal cells on melanogenesis. melDESS is a complex, clinically relevant skin equivalent composed of an epidermis containing both melanocytes and keratinocytes. Its dermal compartment consisted either of adipose tissue-derived stromal cells (ASC), dermal fibroblasts, or a mixture of both cell types...

Recombination events induce significant genetic changes, and this process can result in virus genetic diversity or in the generation of novel pathogenicity. We discovered a new recombinant feline leukemia virus (FeLV) gag gene harboring an unrelated insertion, termed the "X-region", which was derived from FcERV-gamma4, a feline endogenous gammaretrovirus. The identified FcERV-gamma4 proviruses have lost their coding capability, but some can express their viral RNA in feline tissues. Although the X-region-carrying recombinant FeLVs appeared to be replication-defective viruses, they were detected in 6...

BACKGROUND: Varicose veins and chronic venous disease are common, and some funding bodies ration treatment based on a minimum diameter of the incompetent truncal vein. This study assessed the effect of maximum vein diameter on clinical status and patient symptoms. METHODS: A prospective observational cohort study of patients presenting with symptomatic varicose veins to a tertiary referral public hospital vascular clinic between January 2011 and July 2012. Patients underwent standardized assessment with venous duplex ultrasonography, and completed questionnaires assessing quality of life (QoL) and symptoms (Aberdeen Varicose Vein Questionnaire, EuroQol Five Domain QoL assessment and EuroQol visual analogue scale)...

Anteromedial maxillectomy is typically performed in conjunction with low-dose radiotherapy and intraarterial chemotherapy. In doing so, the extent of surgical defects is reduced. However, nasal deviation and oral incompetence may ensue, due to cicatricial contracture of wounds, and may be distressing to these patients. Herein, we report a series of eight free perforator flap procedures (anterolateral thigh [ALT] flap, 6; thoracodorsal artery perforator [TAP] flap, 2) used to correct such deformities. The TAP flap was combined with scapular tip [ST] osseous flap in patients with added zygomatic prominence defects...

Plan Sésame (PS) is a user fee exemption policy launched in 2006 to provide free access to health services to Senegalese citizens aged 60 and over. Analysis of a large household survey evaluating PS echoes findings of other studies showing that user fee removal can be highly inequitable. 34 semi-structured interviews and 19 focus group discussions with people aged 60 and over were conducted in four regions in Senegal (Dakar, Diourbel, Matam and Tambacounda) over a period of six months during 2012. They were analysed to identify underlying causes of exclusion from/inclusion in PS and triangulated with the household survey...
