Saccharomyces cerevisiae variety diastaticus is generally considered to be an obligatory spoilage microorganism and spoilage yeast in beer and beer-mixed beverages (Folz, Hofmann and Stahl 2011; Hutzler et al. 2012). Their super-attenuating ability causes increased carbon dioxide concentrations, beer gushing and potential bottle explosion along with changes in flavor, sedimentation and increased turbidity. This research shows clear differences in the super-attenuating properties of S. cerevisiae var. diastaticus yeast strains and their potential for industrial brewing applications...

BACKGROUND: Transscleral tunnel incisions are commonly made to avoid postoperative leakage in small gauge sutureless vitrectomy. We present an unreported intraoperative complication, tunnel incision related arterial hemorrhage from sclerotomy, in 23-gauge (23G) vitrectomy. CASE PRESENTATION: Two cases of intraocular arterial hemorrhage from superonasal sclerotomy were observed at the beginning of vitrectomy. The bleeding filled the vitreous cavity quickly and gushed out from the incision port after the involved supronasal cannula was removed...

The absence of the yeast protein seripauperin 5 (PAU5) from Saccharomyces cerevisiae has been suggested as a biomarker for the occurrence of gushing in sparkling wine as samples lacking PAU5 were found to be more susceptible to gushing. In this study, further characterization of PAU5 regarding its foam-stabilizing properties was performed to elucidate whether PAU5 has foam-stabilizing properties and therefore, to elucidate a direct influence on the gushing potential of sparkling wines. PAU5 was successfully purified from non-gushing sparkling wine using reversed-phase high-performance liquid chromatography (RP-HPLC)...

Cork popping from clear transparent bottles of champagne stored at different temperatures (namely, 6, 12, and 20 °C) was filmed through high-speed video imaging in the visible light spectrum. During the cork popping process, a plume mainly composed of gaseous CO2 with traces of water vapour freely expands out of the bottleneck through ambient air. Most interestingly, for the bottles stored at 20 °C, the characteristic grey-white cloud of fog classically observed above the bottlenecks of champagne stored at lower temperatures simply disappeared...

Cerebrospinal fluid (CSF) leak is an uncommon event that can occur during stapes surgery. Such leaks can be classified as gushing leaks (stapes gushers) and oozing leaks. A stapes gusher is a massive flow of CSF through the perforated footplate that fills the middle ear suddenly, while an oozing leak is a slower and less profuse flow. We conducted a retrospective, observational, multicenter study of 38 patients-23 men and 15 women, aged 23 to 71 years (mean: 47)-who had experienced a CSF leak during stapes surgery...

A previously healthy man, who had undergone coronary artery bypass 10 years earlier and had been diagnosed with brucellosis due to Brucella septicemia after Brucella arthritis, presented with chest pain and high fever. Anti- Brucella antibiotics were started, but after 4 weeks, his high fever remained. An infected mass was confirmed by computed tomography, and surgical intervention was performed via a median sternotomy. A large amount of thick pus gushed from an abscess in the upper mediastinum. The abscess cavity had a thick granulation wall, and cultured pus was positive for Brucella only...

John Cleland's 1740s pornographic novel, Memoirs of a Woman of Pleasure repeatedly depicts and eroticises the act of defloration. As such it is a revealing illustration of what Ivan Bloch termed the 'defloration mania' of the eighteenth century. This article maps narrative events on to contemporary medical depictions of first intercourse to show the ways that the theories and ideas presented in medical and pseudo-medical texts transferred into erotic fiction and demonstrates how in some instances the bloody defloration scenes can be read as being sex during menstruation, an act which was culturally forbidden at this time...

AIMS: The aim of this study was to elucidate whether grape-associated fungi exert an influence on gushing by their production of surface-active compounds. METHODS AND RESULTS: In preliminary experiments, 58 grape-associated isolates of species within Penicillium and Aspergillus genera were tested for their ability to modify the surface activity of culture supernatants. As the genus Penicillium had a higher potential to change surface activity, further research focused on that genus...

Free fatty acids (FFA) content of beer affects the ability to form a stable head of foam and plays an important role in beer staling. Moreover, the presence of saturated FAs is related sometimes to gushing problems in beer. The aim of this research was to validate an analytical method for the determination of FFAs in beer. The extraction of FFAs in beer was achieved via Liquid-Liquid Cartridge Extraction (LLCE), the FFAs extract was purified by Solid Phase Extraction (SPE), methylated by boron trifluoride in methanol, and injected into GC-FID system...

OBJECTIVE: To explore specific clinical issues, surgical results, and complications of 80 cochlear implantations (CI) in 55 patients with Pendred syndrome (PS) or non-syndromic enlarged vestibular aqueduct (NSEVA). BACKGROUND: Previous studies have focused either on unselected case series or on populations with mixed cochlear malformations. PS/NSEVA accounts for up to 10% of congenital SNHL, rendering this a large group of cochlear implant candidates. The abnormal inner ear anatomy of these patients may be associated with a lower surgical success rate and a higher rate of complications...

Spontaneous oesophageal rupture after swallowing a bolus of food is a very rare condition. In resource-limited settings, it is very challenging to diagnose this condition especially when its presentation is atypical. Its prognosis is very poor when diagnosis is delayed due to risk of mediastinitis. We report a case of 37-year-old man who was admitted to our hospital complaining of sudden onset of chest tightness and pain after a meal 8 h prior to admission. Urgent chest radiograph revealed right hydropneumothorax with collapsed lung...

Fungal hydrophobin is a family of low molecular weight proteins consisting of four disulfide bridges and an extraordinary hydrophobic patch. The hydrophobic patch of hydrophobins and the molecules of gaseous CO2 may interact together and form the stable CO2-nanobubbles covered by an elastic membrane in carbonated beverages. The nanobubbles provide the required energy to provoke primary gushing. Due to the hydrophobicity of hydrophobin, this protein is used as a biosurfactant, foaming agent or encapsulating agent in food products and medicine formulations...

There have been many studies of the diverse impacts of invasions by alien plants but few have assessed impacts on water resources. We reviewed the information on the impacts of invasions on surface runoff and groundwater resources at stand to catchment scales and covering a full annual cycle. Most of the research is South African so the emphasis is on South Africa's major invaders with data from commercial forest plantations where relevant. Catchment studies worldwide have shown that changes in vegetation structure and the physiology of the dominant plant species result in changes in surface runoff and groundwater discharge, whether they involve native or alien plant species...
