This work is an attempt to solve the inverse problem on fractional Fisher's equation. A method comprising of Lubich's approach to discretize the time fractional derivative and differential quadrature ...method with modified B-spline basis function to approximate the space derivatives is proposed to find the numerical solution of the equation. A stable numerical solution is obtained for this problem and then a comparison is made with the existing results. The obtained results are presented in form of tables and figures. The proposed method can be applied to similar fractional equations.
The carbohydrate‐binding molecule galectin‐3 has garnered significant attention recently as a biomarker for various conditions ranging from cardiac disease to obesity. Although there have been ...several recent studies investigating its role in stroke and other cerebrovascular diseases, awareness of this emerging biomarker in the wider neurology community is limited. We performed a systematic search in PubMed, Embase, Scopus, CINAHL, Clinicaltrials.gov and the Cochrane library in November and December 2016 for articles related to galectin‐3 and cerebrovascular disease. We included both human and pre‐clinical studies in order to provide a comprehensive view of the state of the literature on this topic. The majority of the relevant literature focuses on stroke, cerebral ischemia and atherosclerosis, but some recent attention has also been devoted to intracranial and subarachnoid hemorrhage. Higher blood levels of galectin‐3 correlate with worse outcomes in atherosclerotic disease as well as in intracranial and subarachnoid hemorrhage in human studies. However, experimental evidence supporting the role of galectin‐3 in these phenotypes is not as robust. It is likely that the role of galectin‐3 in the inflammatory cascade within the central nervous system following injury is responsible for many of its effects, but its varied physiological functions and multiple sites of expression mean that it may have different effects depending on the nature of the disease condition and the time since injury. In summary, experimental and human research raises the possibility that galectin‐3, which is closely linked to the inflammatory cascade, could be of value as a prognostic marker and therapeutic target in cerebrovascular disease.

Twenty years ago, Hales and Barker along with their co-workers published some of their pioneering papers proposing the ‘thrifty phenotype hypothesis’ in
Diabetologia
(

;35:595–601 and

;36:62–67). ...Their postulate that fetal programming could represent an important player in the origin of type 2 diabetes, the metabolic syndrome and cardiovascular disease (CVD) was met with great scepticism.
More recently, their observations have been confirmed and expanded in many epidemiological and animal experimental studies, and human integrative physiological studies have provided insights into some of the underlying molecular mechanisms. Type 2 diabetes is a multiple-organ disease, and developmental programming, with its idea of organ plasticity, is a plausible hypothesis for a common basis for the widespread organ dysfunctions in type 2 diabetes and the metabolic syndrome. Only two among the 45 known type 2 diabetes susceptibility genes are associated with low birthweight, indicating that the association between low birthweight and type 2 diabetes is mainly non-genetic. Prevention programmes targeting adult lifestyle factors seems unable to stop the global propagation of type 2 diabetes, and intensive glucose control is inadequate to reduce the excess CVD mortality in type 2 diabetic patients. Today, the thrifty phenotype hypothesis has been established as a promising conceptual framework for a more sustainable intergenerational prevention of type 2 diabetes.

Abstract
A complex (dusty) plasma system is well known as a paradigmatic model for studying the kinetics of solid-liquid phase transitions in inactive condensed matter. At the same time, under ...certain conditions a complex plasma system can also display characteristics of an active medium with the micron-sized particles converting energy of the ambient environment into motility and thereby becoming active. We present a detailed analysis of the experimental complex plasmas system that shows evidence of a non-equilibrium stationary coexistence between a cold crystalline and a hot fluid state in the structure due to the conversion of plasma energy into the motion energy of microparticles in the central region of the system. The plasma mediated non-reciprocal interaction between the dust particles is the underlying mechanism for the enormous heating of the central subsystem, and it acts as a micro-scale energy source that keeps the central subsystem in the molten state. Accurate multiscale simulations of the system based on combined molecular dynamics and particle-in-cell approaches show that strong structural nonuniformity of the system under the action of electostatic trap makes development of instabilities a local process. We present both experimental tests conducted with a complex plasmas system in a DC glow discharge plasma and a detailed theoretical analysis.

Chronic pain and functional impairment associated with temporomandibular joint (TMJ) disorders (TMD) considerably reduce oral health-related quality of life (OHRQoL). In the present study we have ...assessed the influence of prolotherapy in patients with TMD by the subjective measurement of QoL using the Oral Health Impact Profile-14 (OHIP-14). Twenty-five patients diagnosed with TMD (mean (range) age 38 (18 – 70) years) were included. They had all undergone dextrose prolotherapy to the TMJ at regular time intervals (four times at intervals of two weeks) using the method suggested by Hemwall-Hackett. They were asked to answer the OHIP-14 questionnaire before and two years after prolotherapy. Seven domains of OHRQoL were rated on a 5-point Likert scale from 0 (never) to 4 (very often). Domain scores and total OHIP-14 scores were compared using inferential statistics (chi squared and Wilcoxon signed rank tests). Prolotherapy was effective over time, as all the domains’ mean scores decreased considerably after treatment. The total mean score before prolotherapy was 21.20, which was extensively reduced to 13.08 after prolotherapy (p=0.001). There was statistically significant improvement in all domains, including functional limitation, physical pain, psychological discomfort, physical disability, psychological disability, social disability, and handicap (p≤0.005 in all cases). We concluded that prolotherapy has a promising role in the improvement of OHRQoL of patients with TMD, and its beneficial effects persist at least two years after treatment.

Several XYZ materials with X and Y as 3d and 4d transition metal elements offer half-metallic magnetic properties. In such half-metallic materials there is a band gap at the Fermi energy for the ...minority spin channel, but not for the majority spin channel. In this work, we present the energy bands and density of states of half-Heusler alloys namely, KCrZ (where Z=S, Se and Te) using first principles full potential linearized augmented plane wave method by applying PBEsol approach of generalised gradient approximation. It is seen that these compounds show half-metallic character with large magnetic moment of about 5.0 μB Density of states and energy bands are analysed to discuss about the origin of large values of spin moment in such compounds.
Sheehan's syndrome (SS) is caused by infarction of the pituitary gland usually precipitated by hypotension due to massive uterine hemorrhage during the peripartum period. Once SS develops, it becomes ...a major comorbidity for the young females and predisposes them to further medical, obstetric, and anesthetic complications. Herein, we report the perioperative anesthetic management of a 28-year-old female, already diagnosed with SS precipitated by urosepsis and septicemic shock in a previous pregnancy, now presenting with twin pregnancy for elective cesarean section. Her magnetic resonance imaging brain revealed pituitary apoplexy and she had hypothyroidism with gestational diabetes mellitus. The overall successful perioperative management of the patient is described along with an emphasis on aggressive management of hypotension due to any cause in the peripartum period to prevent infarction/necrosis of anterior pituitary gland.

Lignocaine is one of the most commonly-used agents to anaesthetise an area preoperatively. It can, however, cause undesirable effects such as burning on injection, relatively slow onset, and ...unreliable, or lack of, numbness when injected into infected tissues as a result of the acidic pH of commercial preparations (the pH is between 3.5 and 7.0 compared with the physiological pH, which is between 7.35 and 7.45). The aim of this comparative study was to evaluate the efficacy of buffered local anaesthetic on infected areas by altering the pH with 8.4% sodium bicarbonate, to measure the pain before and after the injection, and to record the time of onset of anaesthesia. All 60 patients were given 2% lignocaine hydrochloride with adrenaline 1:80,000 and 30 patients were randomly allocated to have 10:1 dilution of 8.4% sodium bicarbonate (study group). Pain was assessed on a visual analogue scale and a verbal rating scale. There was a significant difference in the amount of pain between control and study groups (p=0.025). The mean (SD) time (minutes) to onset of local anaesthesia in the study group was 1.06 (0.25) compared with 2.96 (0.81) in the control group (p<0.001). Our results confirm the efficacy of the buffered local anaesthetic solution in reducing pain on injection and resulting in quicker onset of anaesthesia. Increasing the pH of lignocaine solutions with bicarbonate immediately before use, therefore, should be considered when treating various acute infections of the head and neck.
