Probing phospholipid microbubbles by atomic force microscopy to quantify bubble mechanics and nanostructural shell properties
Microbubbles (MBs), which are used as ultrasonic contrast agents, have distinct acoustic signatures which enable them to significantly enhance visualisation of the vasculature. Research is progressing to develop MBs which act as drug/gene delivery vehicles for site-specific therapeutics. In order to manufacture effective theranostic vehicles, it is imperative to understand the mechanical and nanostructural properties of these agents; this will enrich the understanding of how the structural, biophysical and chemical properties of these bubbles impact their functionality. We produced microfluidic phospholipid-based MBs due to their favourable properties, such as biocompatibility and echogenicity, as well as the ability to modify the shell for targeting applications. We have drawn upon atomic force microscopy to conduct force spectroscopy and tapping-mode imaging investigations. We have, for the first time to our knowledge, been able to accurately quantify the thickness and lipid configuration of phospholipid-shelled MBs - showing a trilayer as opposed to the conventional monolayer structure. Furthermore, we have measured MB stiffness and employed different mechanical theories to quantify the Youngâs modulus. We show that the Reissner theory is inappropriate for mechanical characterisation of phospholipid MBs, however, the Hertz model does offer biologically relevant comparisons. Analysis using the Alexander-de Gennes polymer brush theory has allowed us to provide new information regarding how the thickness of the polyethylene glycol brushes, end-grafted to our phospholipid microbubbles, changes with diameter
The acute effects of Waterpipe smoking on the cardiovascular and respiratory systems
Objective. To assess the acute effects of smoking in Waterpipe (WP) smokers in Ajman, United Arab Emirates (UAE). Context. 202 male volunteers aged > 17 years were included. Blood pressure, heart rate and respiratory rate values of each participant, before and after a 30 minute smoking session, were measured and compared. Standardized questionnaires were also answered.
Results. Mean increases in systolic blood pressure (16 ñ 1 mmHg), diastolic blood pressure (2 ñ 0.7 mmHg), heart rate (6.30 ñ 0.60 bpm) and respiratory rate (2 ñ 2 breathes/min) were observed (p inf. 0.001). 92% of smokers believed Waterpipe smoking (WPS) to be harmful to health and 77% of smokers took up WPS for reasons of leisure. Results from the questionnaire revealed a significant relationship between smokers? beliefs of WPS and attempts to quit smoking ie. smokers who believed waterpipe to be harmful were more likely to try to quit. Educa- tion had influence on smokers ideas on WPS. 69% of smokers who claimed hookah is harmful had university qualification and further 23% has highschool qualification.
Conclusions. Smoking Waterpipe has significant effects on both the cardiovascular and respiratory system. Waterpipe smokers despite sound knowledge, show little concern towards health. Education plays an important role and creates awareness about the hazards of smoking practices, including Waterpipe
Extension of non-minimal derivative coupling theory and Hawking radiation in black-hole spacetime
We study the greybody factor and Hawking radiation with a non-minimal
derivative coupling between the scalar field and the curvature in the
background of the slowly rotating Kerr-Newman black hole.
Our results show that both the absorption probability and luminosity of
Hawking radiation of the scalar field increase with the coupling.
Moreover, we also find that for the weak coupling , the
absorption probability and luminosity of Hawking radiation decrease when the
black hole's Hawking temperature decreases; while for stronger coupling
, the absorption probability and luminosity of Hawking radiation
increase on the contrary when the black hole's Hawking temperature decreases.
This feature is similar to the Hawking radiation in a -dimensional static
spherically-symmetric black hole surrounded by quintessence \cite{chensong}.Comment: 17 pages, 6 figures, 1 table, Title changed, Appendix changed,

Two-Nucleon Momentum Distributions Measured in 3He(e,e'pp)n
We have measured the 3He(e,e'pp)n reaction at 2.2 GeV over a wide kinematic
range. The kinetic energy distribution for `fast' nucleons (p > 250 MeV/c)
peaks where two nucleons each have 20% or less, and the third nucleon has most
of the transferred energy. These fast pp and pn pairs are back-to-back with
little momentum along the three-momentum transfer, indicating that they are
spectators. Experimental and theoretical evidence indicates that we have
measured distorted two-nucleon momentum distributions by striking the third
nucleon and detecting the spectator correlated pair.Comment: 6 pages, 5 figures, submitted to PR
Single pi+ Electroproduction on the Proton in the First and Second Resonance Regions at 0.25GeV^2 < Q^2 < 0.65GeV^2 Using CLAS
The ep -> e'pi^+n reaction was studied in the first and second nucleon
resonance regions in the 0.25 GeV^2 < Q^2 < 0.65 GeV^2 range using the CLAS
detector at Thomas Jefferson National Accelerator Facility. For the first time
the absolute cross sections were measured covering nearly the full angular
range in the hadronic center-of-mass frame. The structure functions sigma_TL,
sigma_TT and the linear combination sigma_T+epsilon*sigma_L were extracted by
fitting the phi-dependence of the measured cross sections, and were compared to
the MAID and Sato-Lee models.Comment: Accepted for publication in PR
Observation of an Exotic Baryon with S=+1 in Photoproduction from the Proton
The reaction was studied at Jefferson Lab using a
tagged photon beam with an energy range of 3-5.47 GeV. A narrow baryon state
with strangeness S=+1 and mass MeV/c was observed in the
invariant mass spectrum. The peak's width is consistent with the CLAS
resolution (FWHM=26 MeV/c), and its statistical significance is 7.8
1.0 ~. A baryon with positive strangeness has exotic structure and
cannot be described in the framework of the naive constituent quark model. The
mass of the observed state is consistent with the mass predicted by a chiral
soliton model for the baryon. In addition, the invariant mass
distribution was analyzed in the reaction with high
statistics in search of doubly-charged exotic baryon states. No resonance
structures were found in this spectrum.Comment: 5 pages, 5 figures, add reference
Photodisintegration of He into p+t
The two-body photodisintegration of He into a proton and a triton has
been studied using the CEBAF Large-Acceptance Spectrometer (CLAS) at Jefferson
Laboratory. Real photons produced with the Hall-B bremsstrahlung-tagging system
in the energy range from 0.35 to 1.55 GeV were incident on a liquid He
target. This is the first measurement of the photodisintegration of He
above 0.4 GeV. The differential cross sections for the He
reaction have been measured as a function of photon-beam energy and
proton-scattering angle, and are compared with the latest model calculations by
J.-M. Laget. At 0.6-1.2 GeV, our data are in good agreement only with the
calculations that include three-body mechanisms, thus confirming their
importance. These results reinforce the conclusion of our previous study of the
three-body breakup of He that demonstrated the great importance of
three-body mechanisms in the energy region 0.5-0.8 GeV .Comment: 13 pages submitted in one tgz file containing 2 tex file and 22

Hyperon Photoproduction in the Nucleon Resonance Region
Cross-sections and recoil polarizations for the reactions gamma + p --> K^+ +
Lambda and gamma + p --> K^+ + Sigma^0 have been measured with high statistics
and with good angular coverage for center-of-mass energies between 1.6 and 2.3
GeV. In the K^+Lambda channel we confirm a structure near W=1.9 GeV at backward
kaon angles, but our data shows a more complex s- and u- channel resonance
structure than previously seen. This structure is present at forward and
backward angles but not central angles, and its position and width change with
angle, indicating that more than one resonance is playing a role. Rising
back-angle cross sections at higher energies and large positive polarization at
backward angles are consistent with sizable s- or u-channel contributions. None
of the model calculations we present can consistently explain these aspects of
the data.Comment: 5 pages, 3 figures, submitted to Physical Review Letter
