New Results from the Search for Low-Mass Weakly Interacting Massive Particles with the CDMS Low Ionization Threshold Experiment.

The CDMS low ionization threshold experiment (CDMSlite) uses cryogenic germanium detectors operated at a relatively high bias voltage to amplify the phonon signal in the search for weakly interacting massive particles (WIMPs). Results are presented from the second CDMSlite run with an exposure of 70 kg day, which reached an energy threshold for electron recoils as low as 56 eV. A fiducialization cut reduces backgrounds below those previously reported by CDMSlite.

First direct limits on lightly ionizing particles with electric charge less than e/6.

While the standard model of particle physics does not include free particles with fractional charge, experimental searches have not ruled out their existence. We report results from the Cryogenic Dark Matter Search (CDMS II) experiment that give the first direct-detection limits for cosmogenically produced relativistic particles with electric charge lower than e/6. A search for tracks in the six stacked detectors of each of two of the CDMS II towers finds no candidates, thereby excluding new parameter space for particles with electric charges between e/6 and e/200.

Double outlet right ventricle, atrioventricular canal defect with severe pulmonary artery stenosis: a rare cyanotic congenital heart disease.

Double outlet right ventricle (DORV) is characterised by arousal of the aorta and the pulmonary vessel from the right ventricle, and is always accompanied by a ventricular septal defect (VSD). Our patient, a twenty days-old female child, presented to the Paediatrics Unit I of Civil Hospital, Karachi, with complaints of generalised cyanosis and reluctance to feed since birth. Apart from the fact that the neonate was cyanosed with increased respiration, the physical examination was unremarkable.

Search for low-mass weakly interacting massive particles with SuperCDMS.

We report a first search for weakly interacting massive particles (WIMPs) using the background rejection capabilities of SuperCDMS. An exposure of 577 kg days was analyzed for WIMPs with mass <30  GeV/c(2), with the signal region blinded. Eleven events were observed after unblinding.

Search for low-mass weakly interacting massive particles using voltage-assisted calorimetric ionization detection in the SuperCDMS experiment.

SuperCDMS is an experiment designed to directly detect weakly interacting massive particles (WIMPs), a favored candidate for dark matter ubiquitous in the Universe. In this Letter, we present WIMP-search results using a calorimetric technique we call CDMSlite, which relies on voltage-assisted Luke-Neganov amplification of the ionization energy deposited by particle interactions. The data were collected with a single 0.

Silicon detector dark matter results from the final exposure of CDMS II.

We report results of a search for weakly interacting massive particles (WIMPS) with the silicon detectors of the CDMS II experiment. This blind analysis of 140.2 kg day of data taken between July 2007 and September 2008 revealed three WIMP-candidate events with a surface-event background estimate of 0.

Coronary heart disease risk-factor profile in a lower middles class urban community in Pakistan.

We determined the risk-factor profile and prevalence of coronary heart disease in Metroville, a lower middle class urban community in Karachi, and compared them to the Pakistan health survey PNHS 1990-94, and the US health and nutrition survey 1988-94 NHANES111. Subjects < 18 years and pregnant women were excluded as were people with extreme ranges BMI [corrected] heart rate, height and waist. The prevalence of hypertension was 23% in men and women, hypercholesterolaemia was 17% in men and 22% in women (P < 0.

Evaluation and comparison of coronary heart disease risk factor profiles of children in a country with developing economy.

Objective: To define the risk factors (RF) profile and prevalence rates of high risk factors in an urban Pakistani community and compare it to the RF profile and prevalence rates of Pakistan National Health Survey.

Methods: The present study included RF relevant data of 400 house hold children selected by open invitation as a part of Metroville Health Study (MHS), a risk factor modification study which was a cooperation between National Heart Lung Blood institute (NHLBI) USA and National Institute of Cardiovascular Diseases Pakistan. The base line data of 389 girls and 417 boys age 5-17 was included.

Efficacy of CVD risk factor modification in a lower-middle class community in Pakistan: the Metroville Health Study.

The Metroville Health Study aimed to reduce consumption of total cooking fats by 33%, salt by 25% and replace ghee with vegetable oil in a lower middle class urban community in Pakistan. Households (n=403) were randomly assigned to Intervention and Control groups. A baseline screening collected data on CVD risk factors, knowledge and attitudes and household consumption of cooking fats and salt.
