The Study to Assess the Effectiveness of Cissus Quadrangularis among Postmenopausal Women with Osteopenia.

Background: Osteopenia refers to bone density that is not only normal but also not as low as that noted in osteoporosis. Osteopenia leads to osteoporosis and increases the risk of fractures. Current research is focused on agents that will prevent or slow the progression of bone loss.

On assessing the carbon capture performance of graphynes with particle swarm optimization.

Tackling climate change is one of the greatest challenges of current times and therefore the development of efficient technologies to limit anthropogenic emissions is of utmost urgency. Recent research towards this goal has alluded to the use of carbon-based solid sorbents for carbon capture. Graphynes (GYs), an interesting class of porous carbon membranes, have recently proven their potential as excellent membranes for gas adsorption and separation.

A Comparative Study of Endoscopic Endonasal Dacryocystorhinostomy Using an Inferiorly Based Flap Versus a Posteriorly Based Flap.

To evaluate the outcome and complications of Endoscopic endonasal Dacryocystorhinostomy (DCR) using an inferiorly based mucosal flap as compared to a conventional posteriorly based mucosal flap with flap preservation and no stenting. 36 patients presenting with nasolacrimal duct obstruction were divided into two groups: the first group underwent endoscopic DCR using an inferiorly based mucosal flap, and the other group used a posteriorly based mucosal flap. In both groups, the mucosal flap was preserved, and bone was removed using Kerrison's punch.

Prevalence of Tonsilloliths in Chronic Rhinosinusitis: A Retrospective CT PNS Study.

To determine the prevalence of tonsilloliths in CT PNS (Computed Tomography ParaNasal Sinuses) of patients with and without features of chronic rhinosinusitis. 97 CT PNS of the patients with features of chronic rhinosinusitis were included in the study group, and 124 CT PNS of cases without features of chronic rhinosinusitis were taken as the control group. All 221 CT PNS were then evaluated for the presence of tonsillar calcifications indicative of tonsilloliths and the prevalence of the same in the study and control groups.

A Terrylene Bisimide based Universal Host for Aromatic Guests to Derive Contact Surface-Dependent Dispersion Energies.

π-π interactions are among the most important intermolecular interactions in supramolecular systems. Here we determine experimentally a universal parameter for their strength that is simply based on the size of the interacting contact surfaces. Toward this goal we designed a new cyclophane based on terrylene bisimide (TBI) π-walls connected by para-xylylene spacer units.
