This study examines the temporal evolution of the tropospheric circulation following large-amplitude variations in the strength of the Southern Hemisphere (SH) stratospheric polar vortex in data from 1979 to 2001 and following the SH sudden stratospheric warming of 2002. In both cases, anomalies in the strength of the SH stratospheric polar vortex precede similarly signed anomalies in the tropo...

This cross-sectional study examined differences in children's health behaviors during school term (ST) versus school holiday (SH: June-July) and how associations changed when weather characteristics were considered. Children aged 5-18 years (n = 406) from a subtropical climate reported behaviors over 20 months. Multivariable regression models controlling for age, sex, race and body mass index z...

Natural product curcumin (Cur) and H2S-releasing prodrug SH-aspirin (SH-ASA) are potential anticancer agents with diverse mechanisms, but their clinical application prospects are restricted by hydrophobicity and limited efficiency. In this work, we coencapsulated SH-ASA and Cur into methoxy poly(ethylene glycol)-poly (lactide-coglycolide) (mPEG-PLGA) nanoparticles through a modified oil-in-wate...

Two thousand three hundred and seventy strains of Shigella dysenteriae, Sh flexneri, and Sh boydii isolated in England and Wales from 1974 to 1978 were tested for resistance to 12 antimicrobial drugs. Eighty per cent of strains were resistant to one or more drugs, with sulphonamide resistance occurring most frequently. Resistance to streptomycin, tetracycline, ampicillin, and chloramphenicol in...

introduction: the purpose of this study was to compare the antimicrobial efficacy of sodium hypochlorite (sh) and calcium hypochlorite (ch) against enterococcus faecalis (e. faecalis) using quantitative real-time polymerase chain reaction (qpcr) analysis and also to compare their cytocompatibility on l929 murine fibroblasts using mossman’s tetrazolium toxicity (mtt) assay. methods and materials...

The association between arachnoid cyst and subdural hygroma (SH) is rare. We report a case, presenting of left middle cranial fossa arachnoid cyst with traumatic SH and spontaneous resolution of SH. The patient was totally asymtomatic prior to the injury and his arachnoid cyst was detected incidentally during investigations following minor head trauma. Our case with normal neurological examinat...

Psychrophilic enzymes evolved from a plethora of structural scaffolds via multiple molecular pathways. Elucidating their adaptive strategies is instrumental to understand how life can thrive in cold ecosystems and to tailor enzymes for biotechnological applications at low temperatures. In this work, we used X-ray crystallography, in solution studies and molecular dynamics simulations to reveal ...

The sh-verification tool supports a verification method for cooperating systems based on formal languages. It comprises computing abstractions of finite-state behaviour representations as well as automata and temporal logic based verification approaches. A small but typical example shows the steps for analysing its dynamic behaviour using the sh-verification tool.
