Ethanologenic fermentation by Parageobacillus thermoglucosidasius with continuous hot microbubble gas-stripping.

The increased use of biofuels in place of fossil fuels is one strategy to support the transition to net-zero carbon emissions, particularly in transport applications. However, expansion of the use of 1st generation crops as feedstocks is unsustainable due to the conflict with food use. The use of the lignocellulosic fractions from plants and/or co-products from food production including food wastes could satisfy the demand for biofuels without affecting the use of land and the availability of food, but organisms which can readily ferment all the carbohydrates present in these feedstocks often suffer from more severe bioethanol inhibition effects than yeast.

Feasibility and Pilot Outcomes of the Move More @ Work Intervention Designed to Encourage Employees to be Physically Active for 2 Minutes After Every 30 Minutes of Sitting.

Objective: The aim of the study is to evaluate the feasibility of a workplace intervention supporting employees to interrupt sitting time with short bouts of activity (termed an opportunity to move [OTM]).

Methods: Using an interrupted time series design, 58 sedentary employees provided baseline assessments of physical activity, health, and work-related outcomes and completed the 12-week intervention. Assessments were repeated immediately and 12 weeks after intervention.

Nature-Based Physical Activity and Hedonic and Eudaimonic Wellbeing: The Mediating Roles of Motivational Quality and Nature Relatedness.

The current study evaluated the degree to which nature-based physical activity (NPA) influenced two distinct types of psychological wellbeing: hedonic wellbeing and eudaimonic wellbeing. The type of motivation an individual experiences for physical activity, and the extent to which individuals have a sense of relatedness with nature, have been shown to influence the specific type of psychological wellbeing that is experienced as a result of NPA. However, the role of these two variables in the relationship between NPA and psychological wellbeing has not been examined.

Continuous removal of ethanol from dilute ethanol-water mixtures using hot microbubbles.

Product inhibition is a barrier to many fermentation processes, including bioethanol production, and is responsible for dilute product streams which are energy intensive to purify. The main purpose of this study was to investigate whether hot microbubble stripping could be used to remove ethanol continuously from dilute ethanol-water mixtures expected in a bioreactor and maintain ethanol concentrations below the inhibitory levels for the thermophile (TM242), that can utilize a range of sugars derived from lignocellulosic biomass. A custom-made microbubble stripping unit that produces clouds of hot microbubbles (~120 °C) by fluidic oscillation was used to remove ethanol from ~2% (v/v) ethanol-water mixtures maintained at 60 °C.

Physical Activity and Psychological Well-Being During the COVID-19 Lockdown: Relationships With Motivational Quality and Nature Contexts.

The COVID-19 pandemic is a global event that has already had substantive negative impacts on psychological well-being. This study investigated the relationship between physical activity (PA) and psychological well-being during a country-wide COVID-19 lockdown in New Zealand. Motivational quality and PA context (nature-based or non-nature-based) were included as potential mediating and moderating variables within this relationship, respectively.

Cognitive sequelae of unilateral posteroventral pallidotomy.

Objective: To examine the cognitive sequelae of unilateral posteroventral pallidotomy.

Design: Single-group pretest and posttest methodologic assessment with baseline evaluation performed 1 to 2 days prior to surgery and follow-up conducted 3 months after pallidotomy.

Setting: Movement disorder clinic at a university medical center.

Unusual manifestations of Epstein-Barr virus encephalomyelitis.

A patient with atypical manifestations of Epstein-Barr Virus (EBV) encephalomyelitis is presented. The patient had unusual spinal fluid immunoglobulin abnormalities, the syndrome of inappropriate anti-diuretic hormone secretion, autonomic dysfunction and spinal arachnoiditis. The cisternal CSF, with a very high IgG level (34.

Anterior spinal artery syndrome with chronic traumatic aortic aneurysm.

Shortly after severe blunt chest trauma, a young man experienced neurological symptoms suggestive of a spinal cord lesion at the lower thoracic level. The symptoms resolved at first, but then recurred 3 years later and progressed slowly. Neurological workup failed to define the cause until a thoracic aortogram showed an aneurysm in the middle portion of the descending aorta in close proximity to a vessel supplying the anterior spinal artery.

The pathogenesis of ischaemic neuronal damage along the cerebral arterial boundary zones in Papio anubis.

The pathogenesis of ischaemic neuronal damage along the arterial boundary zones of the forebrain was investigated in 20 lightly anaesthetized, spontaneously breathing baboons. A combination of bilateral common carotid artery occlusion and systemic hypoxia was used. An arterial PO2 of 21.

Profound hypoxia in Papio anubis and Macaca mulatta--physiological and neuropathological effects. I. Abrupt exposure following normoxia. II. Abrupt exposure following moderate hypoxia.

Lightly anaesthetized and spontaneously breathing P. anubis (PA) and M. mulatta (MM) inhaled at ambient pressure 3.

Cyanide intoxication in Macaca mulatta. Physiological and neuropathological aspects.

Sodium cyanide was infused intravenously in 11 lightly anaesthetised and spontaneously breathing M. mulatta. In most, the EEG, ECG, respiratory rate, blood pressure, cerebral venous sinus pressure, end-tidal pCO2 and body temperature were recorded.

Progressive multifocal leukoencephalopathy in renal transplant recipients.

Progressive multifocal leukoencephalopathy, a slowly progressive papovavirus infection of the CNS, has been reported in more than 110 patients to date, over half of whom have had either leukemia or lymphoma. Our patient is the fourth case of PML occurring after long-term immunosuppression for renal transplantation. We believe that PML is emerging as a potentially serious problem in renal transplant recipients.

Cyanide intoxication in the rat: physiological and neuropathological aspects.

Sodium cyanide was given to rats by intravenous infusion at a rate that would avert apnoea (the first sign of overdosage) in the majority. There was full physiological monitoring in a group under anaesthesia and more limited monitoring in an unanaesthetized group. White matter was damaged in six animals and grey matter additionally in only one.
