Heart Angiotensin-Converting Enzyme and Angiotensin-Converting Enzyme 2 Gene Expression Associated With Male Sex and Salt-Sensitive Hypertension in the Dahl Rat
Angiotensin-converting enzyme 2 (ACE 2) in the heart including its sex dependency in the hypertensive heart, has not been much studied compared to ACE. In the present study, we used the Dahl salt-sensitive rat exposed to fructose and salt to model a hypertensive phenotype in males, females, and ovariectomized females. Blood pressure was measured by the tale-cuff technique in the conscious state. Expression of RAS-related genes ACE, ACE2, angiotensin II receptor type 1, Mas1, and CMA1 in the heart were quantified. The results revealed small but significant differences between male and female groups. The main results indicate the presence of a male preponderance for an increase in ACE and ACE2 gene expression. The results are in accordance with the role of androgens or male chromosomal complement in controlling the expression of the two ACE genes
Positive Mass Theorem for Black Holes in Einstein-Maxwell Axion-dilaton Gravity
We presented the proof of the positive mass theorem for black holes in
Einstein-Maxwell axion-dilaton gravity being the low-energy limit of the
heterotic string theory. We show that the total mass of a spacetime containing
a black hole is greater or equal to the square root of the sum of squares of
the adequate dilaton-electric and dilaton-axion charges.Comment: latex file, to appear in Classical Quantum Gravit

Nursesâ and Doctorsâ Experiences of Transferring Adolescents or Young Adults With Long-Term Health Conditions From Pediatric to Adult Care: A Metasynthesis
The transfer of adolescents and young adults (AYA) with long-term health conditions from pediatric to adult care is a multidisciplinary enterprise where nurses and doctors play an important role. This review aimed to identify and synthesize evidence from qualitative primary reports on how nurses and doctors experience the transfer of AYA aged 13 to 24 years with long-term health conditions to an adult hospital setting. We systematically searched seven electronic databases for reports published between January 2005 and November 2021 and reporting nursesâ and doctorsâ experiences. We meta-summarized data from 13 reports derived from 11 studies published worldwide. Using qualitative content analysis, we metasynthesized nursesâ and doctorsâ experiences into the theme âbeing boosters.â Boosting AYAâs transfer was characterized by supporting AYAâs and their parentsâ changing roles, smoothening AYAâs transition from pediatric to adult care, and handling AYAâs encounters with a different care culture.publishedVersio
Being cross pressured-parents' experiences of the transfer from paediatric to adult care services for their young people with long term conditions:A systematic review and qualitative research synthesis
Background: Family members of young people (13â24 years) with long-term conditions tend to experi- ence multiple challenges when their children transfer from paediatric to adult care, as do the patients themselves.
Objectives: To identify, interpret and theoretically conceptualise the meaning of parentsâ experiences of the transfer from paediatric to adult care of their young people with long-term conditions.
Design: A qualitative research synthesis.
Data sources: We obtained articles from Medline, CINAHL, PsycINFO, EMBASE, Scopus, and Web of Science. Unpublished theses and dissertations were searched for using Google Scholar, Mednar, and ProQuest Dis- sertations and Theses.
Review methods: Based on a previously published protocol, we followed the guidelines from the Joanna Briggs Institute. Sandelowski and Barrosoâs qualitative research synthesis approach guided the metasyn- thesis. Articles published between 1999 and March 2019 were systematically searched for.
Findings: Twenty-three reports from seven Western countries representing 454 parents including signif- icant others such as aunts and grandparents of 462 young people with various diagnoses contributed to the review. âBeing cross-pressuredâ was the metasynthesis found to reflect parentsâ experiences of the transfer from paediatric to adult care of their young people with long-term conditions. The metasynthesis comprised four themes: âFluctuating between parental rolesâ, âNavigating contrasting healthcare contextsâ, âMaking decisions in the face of inner conflictâ, and âTrusting their childâs self-management abilityâ.
Conclusions: Our metasynthesis finding of parentsâ experiences of being cross-pressured provides a new way of thinking about the study phenomena which is supported by transitions theory holding that mul- tiple transitions can take place simultaneously involving myriads of concurrent and conflicting demands. The cross pressure may overwhelm parents. The clinical implications are to recognise parentsâ experi- ences and distress in healthcare planning to promote safe and predicable transfers of their young peo- ple. Provision of healthcare to parents during transfer needs to be tailored to a collaborative decision- making process between parents, their young people, and involved practitioners across paediatric and adult healthcare services.publishedVersio
Two dimensional Sen connections and quasi-local energy-momentum
The recently constructed two dimensional Sen connection is applied in the
problem of quasi-local energy-momentum in general relativity. First it is shown
that, because of one of the two 2 dimensional Sen--Witten identities, Penrose's
quasi-local charge integral can be expressed as a Nester--Witten integral.Then,
to find the appropriate spinor propagation laws to the Nester--Witten integral,
all the possible first order linear differential operators that can be
constructed only from the irreducible chiral parts of the Sen operator alone
are determined and examined. It is only the holomorphy or anti-holomorphy
operator that can define acceptable propagation laws. The 2 dimensional Sen
connection thus naturally defines a quasi-local energy-momentum, which is
precisely that of Dougan and Mason. Then provided the dominant energy condition
holds and the 2-sphere S is convex we show that the next statements are
equivalent: i. the quasi-local mass (energy-momentum) associated with S is
zero; ii.the Cauchy development is a pp-wave geometry with pure
radiation ( is flat), where is a spacelike hypersurface
whose boundary is S; iii. there exist a Sen--constant spinor field (two spinor
fields) on S. Thus the pp-wave Cauchy developments can be characterized by the
geometry of a two rather than a three dimensional submanifold.Comment: 20 pages, Plain Tex, I
Gas filled photonic bandgap fibers as wavelength references
Abstract We demonstrate that air-guiding photonic bandgap fibers filled with various gases, such as acetylene and methane provide optical wavelength references. The constructed devices are compact and cost-effective
