In vitro sensitivity pattern of some urinary tract isolates to Carica papaya extracts

Powdered leaves of Carica papaya(L.) were extracted with ethanol and partitioned in chloroform and distilled water. The extract and fractions were tested for antibacterial activity against clinical isolates of Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis and Pseudomonas species using disc diffusion and microbroth dilution technique. The extract and fractions were further subjected to phytochemical tests for the presence of secondary metabolites using standard procedures. Results of sensitivity test results showed that ethanol extract of the leaf was active against E. coli and K. pneumoniae (7mm each) at 1000μg/disc concentration while chloroform and water fractions of the leaf were active against Escherichia coli, Klebsiella pneumoniae and Proteus mirabilis at 1000μg/disc concentration with zone diameter of 7mm each. Both the extract and fractions were inactive against P. aeruginosa at all concentrations used in this study. The results of phytochemical screening indicated the presence of alkaloids, flavonoids, steroids and tannins in either ethanol extract, fraction(s) or both. This indicates that the Carica papaya has the potential for the production of drugs against organisms causing urinary tract infections.

Laparoscopic salpingectomy and adhesiolysis for concomitant left-sided cornual ectopic gestation and adhesive partial intestinal obstruction: A case report.

Cornual gestation is one of the most hazardous types of ectopic gestation. It carries a significant challenge and a greater maternal mortality risk than ampullary ectopic pregnancy. The diagnosis and treatment are challenging and frequently constitute a medical emergency. Traditionally, the treatment of cornual pregnancy has been hysterectomy or cornual resection at laparotomy. However endoscopic approach is a viable option and consists of conservative techniques such as laparoscopic cornual resection, laparoscopic cornuostomy, laparoscopic salpingectomy or hysteroscopic removal of interstitial ectopic tissue. Case presentation: We report a case of a 28-year-old multipara who had an unruptured left cornual ectopic gestation with moderate pelvic adhesions and concomitant partial intestinal obstruction. She was managed via laparoscopic adhesiolysis and left total salpingectomy. Conclusions: Cornual pregnancy occurs rarely, there is a need for early and prompt diagnosis to prevent potentially fatal complications

Surface Phonon Polariton Modes in Suspended Monolayer Hexagonal Boron Nitrides

Dispersion properties and characteristics of transverse magnetic (TM) and transverse electric (TE) surface phonon polaritons (SPhP) in suspended monolayer hexagonal boron nitrides (hBN) was studied extensively. The analytical results show that the hBN based TM (TE) phonon polaritons exist in restsrahlen bands when imaginary surface conductivity is positive. The effective mode index of TM phonon polaritons is much higher than that of TE phonon polaritons with respective values of ~3000 and ~1.0002 which makes TM SPhP more promising in the practical realization. In addition, the propagation length of TE SPhP is less lossy and surpass that of TM SPhP by factor of 104. This study compares these important properties and sheds more insight into their applications in optical communications, photonics and optoelectronics devices

A photovoltaic system using supercapacitor energy storage for power equilibrium and voltage stability

In a photovoltaic system, a stable voltage and of tolerable power equilibrium is needed. Hence, a dedicated analog charge controller for a storage system which controls energy flow to impose power equilibrium, and therefore, voltage stability on the load is required. We demonstrate here our successful design considerations employing supercapacitors as main energy storage as well as a buffer in a standalone photovoltaic system, incorporating a dedicated supercapacitor charge controller for the first time. Firstly, we demonstrated a photovoltaic system employing supercapacitors as main energy storage as well as a buffer in a standalone photovoltaic system. Secondly, we design a constant voltage maximum power point tracker (MPPT) for peak power extraction from the photovoltaic generator. Thirdly, we incorporated a supercapacitor charge controller for power equilibrium and voltage stability through a dedicated analog charge controller in our design, the first of its kind. Fourthly, we analyzed the use of supercapacitor storage to mitigate disequilibrium between power supply and demands, which, in turn, causes overvoltage or under voltage across the load. Lastly, we then went ahead to demonstrate the control of the energy flow in the system so as to maintain rated voltage across a variant demand load
