Clinical outcomes in the treatment of femoral fracture by using intramedullary femur nailing system

Background: Femoral fractures are frequently occurring fractures that are caused due to large force impaction. The purpose of this study was to clinically evaluate the outcomes of treating femoral fractures with the use of the intramedullary femoral nailing system.Methods: This retrospective clinical trial consists of 32 patients with femoral fracture and are treated by using an intramedullary femoral nailing system which consists of retrograde femoral nail, gamma nails, expert femoral nail, universal intramedullary cannulated femoral nails that are manufactured by Auxein medical Pvt. Ltd. Sonipat, Haryana, India. There were 32 patients from two different hospitals i.e., first hospital group consist of 15 patients (8 male and 7 female) with mean age of 32 years and the second hospital group consist of 17 patients (9 male and 8 female). The fracture categorization was done on the basis of AO Classification of fracture and physical fitness was categorized by American society of anaesthesiologists. VAS score and HHS was used as a criterion for assessing the clinical outcomes of the patients.Results: There were 32 patients to whom surgery was performed and follow up time was 1 month, 3 months, 6 months and 12 months. After the final follow up no patient in any group complaint about the complications or any hardware related problem, there were perfect bone union in every patient. Radiological outcomes also showed proper union at 6 months follow up.Conclusions: For femoral fractures, intramedullary femoral nail gives a better result with high union rate and post-operative composure

Concept of Agni and its Importance in Ayurveda: A Review

The Ayurvedic concept of Agni or fire is critically important to our overall health. Agni is the force of intelligence within each cell, each tissue, and every system within the body. Ultimately, it is the discernment of Agni that determines which substances enter our cells and tissues and which substances should be removed as waste. In this way, Agni is the gatekeeper of life. In fact, according to Ayurveda, when the Agni is extinguished, death soon follows. Ayurveda identifies a vast range of functions for which Agni is directly responsible, but it also teaches us that impaired Agni is at the root of all imbalances and diseases. Ayurveda identifies 13 distinct subtypes of Agni in the body, each defined by its specific physiological function as well as its location in the body. The mother of all of them is Jathara Agni, the central digestive fire that governs the digestion and assimilation of food. But there are many other fire components in the body’s cells, tissues and organs that govern things like sensory perception and the nutrition of specific tissues. Localized manifestations of Agni also determine which substances can cross cell membranes and maintain cellular memory in our DNA. A poor diet, an unsupportive lifestyle, and unresolved emotions can easily hinder Agni by dampening any of these qualities throughout the system. Similarly, nurturing the qualities of Agni in a very general way has the potential to benefit Agni throughout the body. Hence understanding of Agni in one of the important concepts for the understanding of disease process as well as to prescribe principles of treatment

Conserved number fluctuations under global rotation in a hadron resonance gas model

Net-charge, net-strangeness and net-baryon number fluctuations measured in ultra-relativistic heavy-ion collisions may reveal details and insights into the quark-hadron transition, hadrochemical freeze-out and possibly aid in the search of the QCD critical point. By controlling the collision energy, some current and upcoming heavy-ion facilities aim to study high energy nucleus-nucleus collisions in the finite net-baryon density regime where the effects of rapid global rotation are also expected to be strong for the peripheral collisions. We discuss the ratios of conserved number susceptibilities that are experimentally measurable via products of the moments of the corresponding distributions and compute the relevant theoretical results in the framework of a rotating hadron resonance gas (rHRG) model.Comment: 7 pages, 5 figure

Isolation and Structure Elucidation of Quercetin like Structure from Dalbergia sissoo (Fabaceae)

The present study was conducted to isolate and classify Dalbergia sissoo (L.) bioactive compounds. The genus consists of 300 species in India, including 25 species. The generic name Dalbergia honors the 18th century Swedish brothers Nils and Carl Dalberg. Various phytoconstituents of alkaloids, glycosides, flavanoids, tannins, saponins, sterols and terpenoids were isolated and classified from different parts of the plant. Thin Layer Chromatography, High Performance Thin Layer Chromatography, and Column Chromatography were used to isolate spots from the fraction of the crude extract to elucidate the chemical structure of Dalbergia sissoo (L.) leaf extract. Potential spots have been exposed to techniques of FTIR, NMR and mass spectroscopy. Column chromatography was exposed to the raw extract, obtaining 125 fractions, conducting TLC. Among them was a single band in TLC, characterized by FTIR, NMR spectroscopy and mass spectroscopy, and the structure was known as Quercetin. The results of this study indicate the effective potential compound of the ethanolic fraction of Dalbergia sissoo (L.). Keywords: Dalbergia sissoo; Isolation & Structure Elucidation; FTIR; NMR spectroscopy; Mass spectroscopy

Clinical outcomes of fibula bone fracture treated with fibula plate and screws: a retrospective study

Background: The aim of this study was to examine the performance of the plate system with screws while treating Fibula bone fracture.Methods: This was a retrospective study in which 36 patients (27M and 9F) were treated for fibula bone fracture in M.O.H. Jeetoo hospital between September 2020 to December 2021 with a mean follow up of 1 year (1month, 3 months, 6months and 12months). Radiological results at every follow up showed bone union and related complications. Physical fitness of the patients was examined by the American society of anesthesiologists grade and the pain intensity was analyzed by VAS scoring table.Results: The gradually dropping in VAS score indicates positive results to pain management. Consistently, all patients received physiotherapy under physiotherapists. No patient complained of problems or hardware-related issues at the time of the last follow-up, and every patient had proper bone union. At a six-month follow-up, radiological results also indicated proper union.Conclusions: Complications risks are minimal with plate fixation for fibula bone fractures. Better outcomes and accuracy depend upon the surgical skills that can lead to reduced complications

Quantum-enhanced super-sensitivity of Mach-Zehnder interferometer using squeezed Kerr state

We study the phase super-sensitivity of a Mach-Zehnder interferometer (MZI) with the squeezed Kerr and coherent states as the inputs. We discuss the lower bound in phase sensitivity by considering the quantum Fisher information (QFI) and corresponding quantum Cramer-Rao bound (QCRB). With the help of single intensity detection (SID), intensity difference detection (IDD) and homodyne detection (HD) schemes, we find that our scheme gives better sensitivity in both the lossless as well as in lossy conditions as compared to the combination of well-known results of inputs as coherent plus vacuum, coherent plus squeezed vacuum and double coherent state as the inputs. Because of the possibility of generation of squeezed Kerr state (SKS) with the present available quantum optical techniques, we expect that SKS may be an alternative nonclassical resource for the improvement in the phase super-sensitivity of the MZI under realistic scenario.Comment: Comments are welcome
