[1] A series of 24 h mesoscale simulations (of 10 km horizontal and 400 m vertical resolution) are performed to examine the characteristics and forcing of gravity waves (GWs) relative to planetary waves (PWs) during the 2008–2009 major stratospheric sudden warming (SSW). Just prior to SSW occurrence, widespread westward propagating GWs are found along the vortex’s edge and associated predominan...

was even ready to go on duty. He was not allowed to do so but was asked to remain in bed. As the patient had taken quinine, the blood was not examined for malarial parasites. The case was diagnosed as malaria and the usual treatment was adopted, viz:? Mistura quinini hydrochloridi (grs. x to the ounce) three times daily. On the following morning he was given 2 ounces of a saline purgative. The ...

The term acute cerebellar ataxia is used to designate a syndrome of uncertain etiology, occuring usually in young children and characterized by a relatively sudden onset of cerebellar signs (ataxia, intention tremor, and often nystagmus) which reach maximum intensity within a few days and then subside.'` In many of the reported cases an absence of prodromal symptoms, fever, nuchal rigidity, or ...

Ca 2+-Calmodulin (CaM) kinase II (CaMKII) activation depends predominantly on modifications of amino acids within the regulatory domain on this multidomain kinase. A number of mechanisms of activation have been described since the original mode of activation, via Ca 2+ /CaM binding and phosphorylation of a threonine residue in the regulatory domain of CaMKII, was demonstrated. In this issue of ...

BACKGROUND Antineutrophil cytoplasmic antibodies (ANCA)-associated systemic vasculitides have a variety of presentations, but cardiac valvular involvement is rarely diagnosed and its management is not established. CASE PRESENTATION We report the case of a 44 year old man who presented with an ANCA-associated systemic vasculitis and aortic regurgitation of unusual mechanism. Transthoracic and ...

In the present review, the main objective was to describe the epidemiology and clinical features of ciguatera fish poisoning in Hong Kong. From 1989 to 2008, the annual incidence of ciguatera varied between 3.3 and 64.9 (median 10.2) per million people. The groupers have replaced the snappers as the most important cause of ciguatera. Pacific-ciguatoxins (CTX) are most commonly present in reef f...

UNLABELLED Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy and a frequent cause of sick leave because of work-related hand overload. The main treatment is operation. AIM The aim of the study is to assess the usefulness of high frequency ultrasound in the postoperative evaluation of CTS treatment efficacy. MATERIAL AND METHODS Sixty-two patients (50 women and 12 men age...

Introduction. Individual cigarettes are point sources of air pollution; smoking in groups becomes an area source. Outdoor air pollutants from individual point sources are subject to plume rise if the temperature of the smoke plume is hotter than the surrounding air; however if the plume has a small cross-section, as for a cigarette, it will rapidly cool and lose its upward momentum, and then wi...

BACKGROUND Conjunctivitis is the inflammation of the conjunctiva and has 4 main causes-viruses, bacteria, allergens, and irritants. Among these, bacterial conjunctivitis is most common and is contagious, especially when the dentist is working with the infected person, and that person spreads the same to the other patient. METHODS A pretested questionnaire survey was conducted among 152 subjec...

BACKGROUND AND PURPOSE RSA can be used for early detection of unstable implants. We assessed the micromotion of the Mobility Total Ankle System over 2 years, to evaluate the stability of the bone-implant interface using radiostereometric analysis measurements of longitudinal migration and inducible displacement. PATIENTS AND METHODS 23 patients were implanted with the Mobility system. Median ...
