Linear quadratic regulator(LQR) and proportional-integral-derivative(PID) control methods, which are generally used for control of linear dynamical systems, are used in this paper to control the nonlinear dynamical system. LQR is one of the optimal control techniques, which takes into account the states of the dynamical system and control input to make the optimal control *** nonlinear system states are fed to LQR which is designed using a linear state-space model. This is simple as well as robust. The inverted pendulum, a highly nonlinear unstable system, is used as a benchmark for implementing the control methods. Here the control objective is to control the system such that the cart reaches a desired position and the inverted pendulum stabilizes in the upright position. In this paper, the modeling and simulation for optimal control design of nonlinear inverted pendulum-cart dynamic system using PID controller and LQR have been presented for both cases of without and with disturbance input. The Matlab-Simulink models have been developed for simulation and performance analysis of the control schemes. The simulation results justify the comparative advantage of LQR control method.

Objective: To undertake metabolite profiling of various plant parts of Citrullus colocynthis, and assess antioxidant and wound healing activities of fractions for therapeutical applications. Methods: Extracts from leaves, stem, root, fruit pulp and seeds were analyzed using gas chromatography-mass spectrometry and high performance liquid chromatography. Variation in antioxidant potential was assayed by 1,1-diphenyl-2-picrylhydrazyl(DPPH) free radical scavenging assay. The extract with highest antioxidant potential was subjected on in-vivo wound healing activity using excision wound model. Results: Metabolite profiling of Citrullus colocynthis identified 70 chemically diverse metabolites from different plant parts by using a combination of GC-MS and HPLC. Concentration of colocynthin, a principal active secondary metabolite, ranged from 3.15 mg/g dry weight to 242.00 mg/g dry weight, the lowest being in leaves and highest in fruit pulp. DPPH radical scavenging activity of free radical(IC50) ranged from 196.44 μg/mL in fruit pulp to 413.33 μg/mL in leaves tissues. Significant wound contraction and increase in hydroxyproline content of granulation tissue were observed with ointment formulated from methanolic extract of fruit pulp. Conclusions: The study indicates that the methanol extract of Citrullus colocynthis fruit pulp when applied topically may promote wound contraction in rat model attributable to the accumulation of colocynthin. The high quantity of colocynthin(242.00 mg/g dry weight) and substantial concentration of 2,4-di-tert butyl phenol(3.2%), squalene(4.2%) and δ-tocopherol(2.5%) make this plant to provide new opportunities for development of medicinal, nutraceutical and dietary supplements with optimized functionality.

AIM To investigate the association of NFKB1 gene-94 ATTG insertion/deletion(rs28362491) polymorphism with inflammatory markers and risk of diabetic nephropathy in Asian *** A total of 300 subjects were recruited(100 each), normoglycemic,(NG); type 2 diabetes mellitus(T2DM) without any complications(DM) and T2 DM with diabetic nephropathy [DM-chronic renal disease(CRD)]. Analysis was carried out by polymerase chain reaction-restriction fragment length polymorphism and ELISA. Pearson's correlation, analysis of variance and logistic regression wereused for statistical *** The allelic frequencies of-94 ATTG insertion/deletion were 0.655/0.345(NG), 0.62/0.38(DM) and 0.775/0.225(DM-CRD). The-94 ATTG ins allele was associated with significantly increased levels of urinary monocyte chemoattractant protein-1(u MCP-1); u MCP-1(P = 0.026) and plasma tumor necrosis factor-alpha(TNF-α); TNF-α(P = 0.030) and almost doubled the risk of diabetic nephropathy(OR = 1.91, 95%CI: 1.080-3.386, P = 0.025).CONCLUSION-94 ATTG ins/ins polymorphism might be associated with increased risk of developing nephropathy in Asian Indian subjects with diabetes mellitus.

Moringa oleifera Lam.(Shigru)(Moringaceae family) is a traditional medicine used for control of diabetes, obesity, asthma, and cardiac,liver, gastrointestinal, infective, and brain disorders, such as depression and Alzheimer's disease. In Ayurvedic literature, Shigru is among few drugs having Balya(nourishing) as well as Medohara(antiobesity) property. This review focuses on valid connections between the properties documented in ancient literature and current pharmacological knowledge of Moringa, including pharmacological actions, phytochemistry,botanical description, and how Moringa can tackle malnutrition in India, especially Chhattisgarh. All information about M. oleifera was obtained from electronic scientific databases such as PubMed, Web of Science, Scopus, ScienceDirect, Elsevier, Google Scholar, Traditional Knowledge Digital Library, and Indian Traditional Books(Ancient Ayurveda literatures, The Wealth of India, and The Ayurvedic Formulary of India), postgraduate/doctoral thesis, and googling the keyword M. oleifera. M. oleifera have anti-oxidant, antimicrobial, anti-diabetic,anti-obesity, anti-inflammatory, cardioprotective, hepatoprotective, neuroprotective, gastroprotective, wound-healing properties and it can potentially tackle malnutrition. This review describes the key information related to botanical description of M. oleifera, phytochemistry,pharmacological actions, clinical studies, toxicological studies, better utilization as food therapeutics, and ethnobotanical and evidence-based comparative review of M. oleifera. M. oleifera can effectively tackle malnutrition in India, especially Chhattisgarh. The authors emphasize the need for future in-depth ethnopharmacological lead-based research and clinical studies to expand M. oleifera pharmacological activities,clinical efficacy, and safety.
