Fabrication of Zinc Doped Titanium Dioxide Nanoparticles to Inhibit Growth and Proliferation of Liver Cancer Cells (HepG2).

The current research is related to the synthesis of different concentrations (0, 3, and 7 wt %) Zn doped TiO-NPs by using the coprecipitation method. The rutile, anatase crystal structure appeared on different diffracted peaks in TiO-NPs, and the crystallite size (12 to 24 nm) was calculated by using XRD analysis. The spherical, irregular, porous grain-like surface morphology was observed by SEM analysis, and the identification of different functional modes such as hydroxyl, -C-O, -C-O-C, and Ti-O-Ti attached on the surface of the spectrum was examined via FTIR analysis.

Distant entanglement via photon hopping in a coupled cavity magnomechanical system.

We theoretically propose a scheme to generate distant bipartite entanglement between various subsystems in coupled magnomechanical systems where both the microwave cavities are coupled through single photon hopping coupling strength Γ. Each cavity contains a magnon mode and phonon mode and this gives six excitation modes in our model Hamiltonian which are cavity-1 photons, cavity-2 photons, magnon and phonon in cavity-1, and magnon and phonon in cavity-2. We found that significant bipartite entanglement exists between indirectly coupled subsystems in coupled microwave cavities for an appropriate set of parameters regime.

Optomechanically induced transparency in multi-cavity optomechanical system with and without one two-level atom.

We analytically study the optomechanically induced transparency (OMIT) in the N-cavity system with the Nth cavity driven by pump, probing laser fields and the 1st cavity coupled to mechanical oscillator. We also consider that one atom could be trapped in the ith cavity. Instead of only illustrating the OMIT in such a system, we are interested in how the number of OMIT windows is influenced by the cavities and the atom and what roles the atom could play in different cavities.

Emerging role of traditional birth attendants in mountainous terrain: a qualitative exploratory study from Chitral District, Pakistan.

Objectives: This research endeavours to identify the role of traditional birth attendants (TBAs) in supporting the maternal, newborn and child health (MNCH) care, partnership mechanism with a formal health system and also explored livelihood options for TBAs in the health system of Pakistan.

Setting: The study was conducted in district Chitral, Khyber Pakhtunkhwa province, covering the areas where the Chitral Child Survival programme was implemented.

Participants: A qualitative exploratory study was conducted, comprising seven key informant interviews with health managers, and four focus group discussions with community midwives (CMWs), TBAs, members of Community Based Saving Groups (CBSGs) and members of village health committees (VHCs).

Analytical, nutritional and biological evaluation of various brands of fortified and non-fortified wheat flour.

In Pakistan, a funded flour fortification program was launched for malnourished population, residing mainly in rural low income areas, but the urban population having comparatively better nutritional as well as economic status was focused wherein excessive intake of fortificants might cause complications. Therefore, the present study describes the physicochemical properties, elemental composition, nutritional components and hemoglobin/ferritin increasing potential of fortified and non-fortified flour. Domesticated chicken (Gallus gallus domesticus), either sex, age one month, weight 380 ± 18.

Pakistan's health system: performance and prospects after the 18th Constitutional Amendment.

Pakistan has undergone massive changes in its federal structure under the 18th Constitutional Amendment. To gain insights that will inform reform plans, we assessed several aspects of health-systems performance in Pakistan. Some improvements were noted in health-systems performance during the past 65 years but key health indicators lag behind those in peer countries.
