In this paper the numerical analysis of flow and time dependent heat transfer of micro-tube conveying nanofluid in laminar flow is investigated. In this study, convection heat transfer of nanofluid and base fluid and transient analysis for time-varying heat flux for time step of 0.0001 second are elucidated. It is observed that the pumping power of nanofluid flowing and the maximum temperatur...

The leaves are used ethnomedicinally in Nigeria and other parts of the world for insomnia and anxiety among other uses. The investigations sought scientific evidence for the ethnomedicinal use of the leaves for the management of insomnia and anxiety as well as the neural mechanisms for the activities. The sedative and anxiolytic effects of the extracts of the leaves of Stachytarpheta cayennensi...

Rooibos tea was extracted with boiling water. The aqueous extract was chromatographed in a Diaion HP20 column eluted stepwise with water, 25%, 50% and 75% (v/v) aqueous methanol, and 100% methanol. The water eluate (fraction A) showed an augmenting effect on anti-ovalbumin (anti-OVA) immunoglobulin M (IgM) production in OVA-stimulated murine splenocytes in vitro. Fraction A also showed a strong...

Qualitative and quantitative abnormalities in primary components of the tear can alter the dynamics of the lacrimal film, compromising its function. Lipids, an aqueous fraction and mucoproteins constitute the lacrimal film. Keratoconjunctivitis sicca (KCS) is a disease commonly diagnosed in dogs. It is characterized by the deficiency of the aqueous fraction in the lacrimal film that results in ...

BACKGROUND The relationship between whole spectrum of Ejection fraction (EF) and cardioembolic stroke (CES) outcome has not been fully described yet. Notably, it remains unclear whether borderline EF (41∼49%) is related with poor outcome after CES. We sought to evaluate whether lower ejection fraction and borderline EF could predict the outcome in patients with CES. METHOD AND RESULTS We eval...

Trypanosomosis is a debilitating disease affecting mainly livestock and humans in tropical Africa. Chemically synthesized drugs and medicinal plants have been used in the treatment and control of this disease. In this study, the in vitro effect of aqueous extracts and fraction IV extract of Ximenia americana stem bark on Trypanosoma congolense DNA was investigated. The extracts were incubated w...

OBJECTIVE To examine the prevalence of atrial fibrillation (AF) and cardiac structural characteristics in Indigenous and non-Indigenous Australians. DESIGN Retrospective cross-sectional study linking clinical, echocardiography and administrative databases over a 10-year period. SETTING A tertiary, university teaching hospital in Adelaide, Australia. PARTICIPANTS Indigenous and non-Indigen...

Background The association between circulating adiponectin levels and atrial fibrillation (AF) is uncertain. We, therefore, investigated whether an increased serum adiponectin level is implicated in the long-term recurrence of AF after ablation therapy. Methods Our study included 100 consecutive patients (88 men; median age, 57.9±10.9 years) who underwent catheter ablation for AF at our hospi...

BACKGROUND It is unclear if the presence of atrial fibrillation (AF) on admission is associated with worse in-hospital outcomes in patients hospitalized with heart failure (HF). This study evaluated the clinical characteristics, management, length of stay, and mortality of HF patients with and without AF. METHODS AND RESULTS We studied 99 810 patients from 255 sites admitted with HF enrolled ...
