Surface Waves In Homogeneous Visco-Elastic Media Of Higher Order Under The Influence Of Gravity And Surface Stresses

The aim of the present paper is to investigate the surface waves in a homogeneous, isotropic, visco-elastic solid medium of nth order, including time rate of strain under the influence of gravity and surface stresses. The theory of generalized surface waves is developed to investigate particular cases of waves such as the Stoneley, Rayleigh and Love waves. Corresponding equations have been obtained for different cases. These reduced to classical results, when the effects of gravity, surface stresses and viscosity are ignored. Keywords: Gravity, Surface waves, Visco-elasticity, Surface stresses

ESTABLISHMENT OF A MECHANISM OF POLYHERBAL FORMULATION FOR ANTI-RHEUMATISM

Objective: A marketed product Dr. Ortho has been used by many patients and is gaining a positive feedback from the patients. A study is designed to establish its mechanism of action on various anti-rheumatic models in experimental animals. No studies have been investigated on this product for its anti-rheumatic activity.Methods: Dr. Ortho (55 mg/kg, p. o.) was administered during adjuvant-induced arthritis, phlogistic agents (Histamine, bradykinin, and serotonin) induced paw edema, Acetic acid induced writhing test in mice, and Eddy's hot plate. Histopathology (T. S. of knee joint) and various hematological parameters (WBC's, RBC's, and ESR count) were observed during the study.Results: Dr. Ortho decreases arthritis induced inflammation by antagonizing or inhibiting the inflammatory mediators, i.e., histamine, 5-hydroxy tryptamine and bradykinin. (20% (P<0.05) of carrageenan, 10.01%, (P<0.05) of histamine, 8% (P<0.05) of 5-hydroxy tryptamine induced paw volume). Dr. Ortho acts as both peripheral and central analgesic. Histopathology findings revealed that there is a reduction in the neutrophil infiltration, pannus formation, and bone. Hematological parameters show that Dr. Ortho decreases the elevated level of the WBC's count.Conclusion: The present study revealed some facts regarding the mechanism of Dr. Ortho in reducing arthritis induced inflammation. However study may be done further to illustrate its complete mechanism.Â

Factors Associated with Revision Surgery after Internal Fixation of Hip Fractures

Background: Femoral neck fractures are associated with high rates of revision surgery after management with internal fixation. Using data from the Fixation using Alternative Implants for the Treatment of Hip fractures (FAITH) trial evaluating methods of internal fixation in patients with femoral neck fractures, we investigated associations between baseline and surgical factors and the need for revision surgery to promote healing, relieve pain, treat infection or improve function over 24 months postsurgery. Additionally, we investigated factors associated with (1) hardware removal and (2) implant exchange from cancellous screws (CS) or sliding hip screw (SHS) to total hip arthroplasty, hemiarthroplasty, or another internal fixation device. Methods: We identified 15 potential factors a priori that may be associated with revision surgery, 7 with hardware removal, and 14 with implant exchange. We used multivariable Cox proportional hazards analyses in our investigation. Results: Factors associated with increased risk of revision surgery included: female sex, [hazard ratio (HR) 1.79, 95% confidence interval (CI) 1.25-2.50; P = 0.001], higher body mass index (fo

A newly developed assessment tool on collaborative role of doctor–pharmacist in patient medication management

Background Poor communication is one of the most important common factor contributing to medication errors. Despite their common history, there are many intellectual and practical differences between the professions of medicine and pharmacy that eventually affects patient care and health outcomes. Objectives. The main objective of the study is to evaluate the coordination and teamwork between pharmacist and doctor to provide betterment in the care of the patient health. Material and methods . A questionnaire of 10 questions was developed each for the patient, pharmacist and doctor posted on District Hospital, Moradabad (U.P.), India and data collected from the patient and medical professionals through questionnaire were analyzed for collaborative role of doctor-pharmacist with respect to patient care. The results were analyzed using Graph Pad Prism 5. Results. The data obtained from the questionnaire highlights a significant effort between pharmacist and doctors. However, some patients often doubt in the skills of pharmacist for treatment outcome, but the majority of people responds positive to doctor-pharmacist role as they prove to be fruitful in removing medication errors. Conclusions . To facilitate the patient care, doctor-pharmacist alliance is necessary, desired and should be motivated as professed by the respondents. Collaboration is an important element of effective patient-focused health care delivery

A study of BF<SUB>3</SUB>-promoted ortho lithiation of anilines and DFT calculations on the role of fluorine-lithium interactions

Director's cut: The poor directing ability of the dimethylamino group in directed ortho metalation is altered by complexation to BF3, which makes it more strongly activating than methoxy and chloro groups. DFT calculations of simplified lithiated intermediates reveal a small role of the inductive effect, but a distinctive FLi interaction that leads to a F-Li distance which is remarkably similar to the C-Li distance

Prophylactic biological mesh reinforcement versus standard closure of stoma site (ROCSS): a multicentre, randomised controlled trial

Background: Closure of an abdominal stoma, a common elective operation, is associated with frequent complications; one of the commonest and impactful is incisional hernia formation. We aimed to investigate whether biological mesh (collagen tissue matrix) can safely reduce the incidence of incisional hernias at the stoma closure site. Methods: In this randomised controlled trial (ROCSS) done in 37 hospitals across three European countries (35 UK, one Denmark, one Netherlands), patients aged 18 years or older undergoing elective ileostomy or colostomy closure were randomly assigned using a computer-based algorithm in a 1:1 ratio to either biological mesh reinforcement or closure with sutures alone (control). Training in the novel technique was standardised across hospitals. Patients and outcome assessors were masked to treatment allocation. The primary outcome measure was occurrence of clinically detectable hernia 2 years after randomisation (intention to treat). A sample size of 790 patients was required to identify a 40% reduction (25% to 15%), with 90% power (15% drop-out rate). This study is registered with ClinicalTrials.gov, NCT02238964. Findings: Between Nov 28, 2012, and Nov 11, 2015, of 1286 screened patients, 790 were randomly assigned. 394 (50%) patients were randomly assigned to mesh closure and 396 (50%) to standard closure. In the mesh group, 373 (95%) of 394 patients successfully received mesh and in the control group, three patients received mesh. The clinically detectable hernia rate, the primary outcome, at 2 years was 12% (39 of 323) in the mesh group and 20% (64 of 327) in the control group (adjusted relative risk [RR] 0·62, 95% CI 0·43–0·90; p=0·012). In 455 patients for whom 1 year postoperative CT scans were available, there was a lower radiologically defined hernia rate in mesh versus control groups (20 [9%] of 229 vs 47 [21%] of 226, adjusted RR 0·42, 95% CI 0·26–0·69; p<0·001). There was also a reduction in symptomatic hernia (16%, 52 of 329 vs 19%, 64 of 331; adjusted relative risk 0·83, 0·60–1·16; p=0·29) and surgical reintervention (12%, 42 of 344 vs 16%, 54 of 346: adjusted relative risk 0·78, 0·54–1·13; p=0·19) at 2 years, but this result did not reach statistical significance. No significant differences were seen in wound infection rate, seroma rate, quality of life, pain scores, or serious adverse events. Interpretation: Reinforcement of the abdominal wall with a biological mesh at the time of stoma closure reduced clinically detectable incisional hernia within 24 months of surgery and with an acceptable safety profile. The results of this study support the use of biological mesh in stoma closure site reinforcement to reduce the early formation of incisional hernias.
