Published: October 2016

Invertases (beta-D-fructofuranosidase, E.C. 3.2.1.26) are the key enzymes involved in sucrose metabolism in sugarcane plants. They are highly correlated with sucrose and reducing sugar contents during plant growth. The sugarcane plants have two kinds of invertases, namely neutral invertase (NI) and acid invertase (AI). They have different function in sucrose accumulation. The research aimed to study the role of AI and NI in accumulation of reducing sugar during storage of sugarcane stems. Plant materials of 18-month-old field grown sugarcane of the commercial variety R-579 (wet-land) and M 442-51 (dry-land) were used. Three internodes were sampled to represent immature (internode 1-8/F1), maturing (internode 9-16/F2), and mature (internode 17-24/F3) stem tissues. All tissues were stored for 0-9 days at room temperature (28-32oC) and each day, the sample<br />was extracted to determine invertase activity, total soluble protein, and sugar contents. This observation was valid for invertase activity expressed on a protein basis. At the initiate<br />harvested (0-3 days), NI had a higher specific activity than AI in the sucrose-accumulating region of the sugarcane stems. Negative significant correlation was found between NI specific activity and sucrose accumulation (r2 = 0.41, P &lt; 0.05). AI showed a higher specific activity after 4 days harvested and had negative correlation with sucrose accumulation (r2 = 0.40, P &lt; 0.05). These results showed that NI could be more responsible in sucrose hydrolisis than AI at early storage of sugarcane stems.

Published: October 2016

Scars on mangosteen fruits caused by thrips are the most prominent constraint in Indonesian export of mangosteen. Most of the exported mangosteen are rejected due to scar appearance. This research aimed to study the effects of fruit bagging, sanitation, and sticky trap application on the scar intensity on mangosteen. The research was conducted at a farmer's polycultured mangosteen orchard in Lima Puluh Kota, West Sumatra, Indonesia from September 2006 to February 2007. The mangosteen trees were cultured with cacao and coconut. To study the effects of bagging on the number of scars, the fruits were individually bagged at different time points starting from the time of calyx falling down (0) followed at 2, 4, 6, 8, 10, 12, and 14 weeks later. Each treatment was replicated six times. The experiment of sanitation (SNT) and yellow fluorescent sticky trap (YST) application was designed in a completely randomized design with six replications, except for the control which was replicated only three times. Four treatments studied were SNT, YST, combination of SNT+YST, and control. The sanitation was applied by removing all weeds under the canopy of mangosteen trees followed with soil tillage and fogging. The sticky trap was nailed on woody sticks and placed on 3 m above the ground at four different positions around the tree canopy. Parameters observed were the percentage and intensity<br />of scars and number of thrips caught on the sticky traps. The results showed that application of early bagging, SNT, YST, and SNT+YST were effective to reduce intensity and percentage of scars. However, combination of SNT+YST demonstrated the best results in reducing the intensity and percentage of scars by 32.14% and 42.82%, respectively. Combination of SNT+YST also drastically decreased thrips population as indicated by the<br />low number of thrips catched after five biweekly observations. Since the fifth observation, the thrips population was low (less than 5 thrips catched per sticky trap) and far below the economic threshold. The present study implies the importance of early fruit bagging, sanitation, and sticky trap application in protecting mangosteen fruits from scars.

Producing-Gas/Oil-Ratio Behavior of Multifractured Horizontal Wells in Tight Oil Reservoirs
Authors: Jones R. Steven 
Published: October 2016

Summary
Horizontal wells with hydraulic fractures in tight oil reservoirs show producing-gas/oil-ratio (GOR) behavior that is very different from conventional, higher-permeability reservoirs. This paper explains the reasons for the observed behavior by use of reservoir simulation, with field examples from the STACK and SCOOP plays of the Anadarko Basin in central Oklahoma.
A framework for interpreting observed GOR behavior in tight black-oil reservoirs is modeled after the following stages in a well's history. Some stages may not be visible because of the degree of undersaturation, flowing-bottomhole-pressure schedule, finite-conductivity fractures, and duration of the transient-flow period.
Stage 1: Early GOR is constant at the initial solution GOR (Rsi) while bottomhole flowing pressure is above the bubblepoint. Stage 2: A rise in GOR as bottomhole flowing pressure declines to less than the bubblepoint. Stage 3: The transient GOR “plateau”, which is characteristic of transient linear flow. Stage 4: A continuous rise in GOR during boundary-dominated flow.
Fundamental differences between linear and radial flow, which cause the dependence of GOR on flowing bottomhole pressure, are explained by use of simulation. During transient linear flow, the GOR response to changes in flowing bottomhole pressure is independent of permeability for infinite-conductivity fractures, but not for finite-conductivity fractures.
Several practical observations are made. Knowing Rsi and the transient-GOR-plateau level in an area can help one interpret where a well is in its GOR history. Rate-transient-analysis (RTA) diagnostic plots are altered by rising GOR, and sometimes show an early unit slope. During boundary-dominated flow, GOR is more a function of cumulative production than of time; wells with closer fracture spacing have a faster GOR rise with time, but also recover oil more quickly. If compound linear flow develops, GOR can decline late in the well life. The Meramec and Woodford formations in STACK can be history matched without invoking a suppressed bubblepoint caused by pore-proximity effects. The critical gas saturation in the Meramec appears to be in the range of 0–5%.
Technical contributions include a framework for interpreting GOR behavior over well life; the effect of changing bottomhole flowing pressure on GOR; the effect of fracture spacing, conductivity, and half-length on GOR; and the effect of GOR on RTA diagnostic plots.
Anaesthetic approach to VATS in a patient with one lung
Authors: Leong Adeline , Hwang Nian Chih 
Published: October 2016

SummarySpontaneous pneumothorax after a contralateral pneumonectomy is a potentially fatal condition. It can be treated with pleurodesis via video‐assisted thoracoscopic surgery. However, achieving sufficient lung deflation to perform this whilst maintaining good oxygenation in a patient with a single lung is challenging. We describe the anaesthetic management of a 47 year‐old male who underwent left‐sided video‐assisted thoracoscopic pleurodesis for a life‐threatening pneumothorax with a previous right pneumonectomy. We used total intravenous anaesthesia for induction and maintenance of anaesthesia with intermittent apnoeic ventilation. Both adequate surgical field visualisation and oxygenation were achieved. He had an uneventful postoperative course.
A case of suicide by hydrogen sulphide poisoning in the UK
Authors: Willder Jennifer M , Tullett William , Doherty Pamela 
Published: October 2016

SummaryHydrogen sulphide is a colourless, flammable gas with the characteristic odour of rotten eggs. Inhalation of hydrogen sulphide is toxic to humans as it inhibits aerobic metabolism resulting in cellular hypoxia and lactic acidosis. Cases of hydrogen sulphide poisoning in the United Kingdom (UK) are usually occupational in nature occurring via accidental exposure in related industries. Although national statistical data identified 14 cases of suicide by hydrogen sulphide gas in England and Wales between 2001 and 2011, none of these have been previously published. We present the first case of suicide by hydrogen sulphide poisoning in the UK reported in the medical literature.
Complete sacral agenesis: successful spinal anaesthesia for Caesarean section
Authors: Fitzmaurice Bethany , Greenwood Jaime , Alexander Ratan 
Published: October 2016

SummaryWe discuss the case of a female with complete sacral agenesis scheduled for an elective caesarean section. Patients with this condition present a challenge to the anaesthetist, and usually receive a general anaesthetic, due to concerns regarding the precise underlying anatomy and the unpredictability of local anaesthetic spread. We believe that this is the only reported case of a patient with complete sacral agenesis undergoing spinal anaesthesia for an elective caesarean section.
Improvement in Cardiopulmonary Exercise Test results following lifestyle changes and modest exercise at home
Authors: Smith Matthew , Krige Anton 
Published: October 2016

SummaryCardiopulmonary exercise testing is commonly used in the pre‐operative assessment of patients due to have major elective surgery. The measurement of anaerobic threshold has been shown to be an accurate predictor of mortality in major abdominal surgery. Pre‐operative lifestyle changes and aerobic exercise training may improve results and reduce hospital length of stay, morbidity and mortality.We discuss a patient with poor cardiopulmonary exercise testing results who was scheduled for elective anterior resection surgery for a sigmoid colon carcinoma. Surgery was considered extremely high risk. The patient made significant lifestyle changes and commenced a modest amount of aerobic exercise at home. Repeat testing showed much improved results, allowing surgery to proceed.
Mastocytosis: anaphylaxis following emergency anaesthesia
Authors: Baker Roisin , McAlindon Michael , Pierson Richard 
Published: October 2016

SummaryGeneral anaesthesia in patients with known mastocytosis can be extremely hazardous. Massive histamine release may be triggered by drugs or by the psychological and environmental stresses associated with surgery and can result in significant cardiovascular collapse, respiratory compromise and even death. We present a case of anaphylaxis following induction of anaesthesia in a patient whose diagnosis of mastocytosis was not disclosed during pre‐assessment for emergency surgery. We believe it is the only case reported where the patient has survived their hospital admission in such circumstances despite significant and prolonged cardiovascular compromise.
Successful tracheal intubation in a patient with trismus using the X blade and McGrath videolaryngoscope
Authors: Sugiyama Takuji , Matsumoto Sho , Oda Seiko , Shindo Kazuo 
Published: October 2016

SummaryThe McGrath® MAC videolaryngoscope is designed for difficult airways and several standard blades are available. In July 2014, the X blade, with a more acute anterior curvature and slimmer profile than standard blades, entered the Japanese market. We report a case of successful tracheal intubation in a patient with trismus using the X blade. A 59‐yr‐old female presented for right upper lobectomy due to suspected lung cancer. After induction of general anaesthesia, mouth opening was limited to only 15 mm, possibly due to a temporomandibular disorder. We were able to insert the X blade without difficulty and visualise the glottis. Advancing the tracheal tube through the glottis was difficult, so we inserted a catheter through the tracheal tube. We could then advance the tracheal tube over the catheter into the trachea. Combination of the X blade and an introducer may be an option when faced with a difficult airway, especially due to trismus.

ABSTRACT
We present the analysis of the planetary microlensing event OGLE-2014-BLG-1760, which shows a strong light-curve signal due to the presence of a Jupiter mass ratio planet. One unusual feature of this event is that the source star is quite blue, with

. This is marginally consistent with a source star in the Galactic bulge, but it could possibly indicate a young source star on the far side of the disk. Assuming a bulge source, we perform a Bayesian analysis assuming a standard Galactic model, and this indicates that the planetary system resides in or near the Galactic bulge at

. It also indicates a host-star mass of

, a planet mass of

, and a projected star–planet separation of

au. The lens–source relative proper motion is

mas yr−1. The lens (and stellar host star) is estimated to be very faint compared to the source star, so it is most likely that it can be detected only when the lens and source stars start to separate. Due to the relatively high relative proper motion, the lens and source will be resolved to about ∼46 mas in 6–8 yr after the peak magnification. So, by 2020–2022, we can hope to detect the lens star with deep, high-resolution images.

ABSTRACT
We report on the discovery and characterization of the transiting planet K2-39b (EPIC 206247743b). With an orbital period of 4.6 days, it is the shortest-period planet orbiting a subgiant star known to date. Such planets are rare, with only a handful of known cases. The reason for this is poorly understood but may reflect differences in planet occurrence around the relatively high-mass stars that have been surveyed, or may be the result of tidal destruction of such planets. K2-39 (EPIC 206247743) is an evolved star with a spectroscopically derived stellar radius and mass of

and

, respectively, and a very close-in transiting planet, with

. Radial velocity (RV) follow-up using the HARPS, FIES, and PFS instruments leads to a planetary mass of

. In combination with a radius measurement of

, this results in a mean planetary density of

g cm−3. We furthermore discover a long-term RV trend, which may be caused by a long-period planet or stellar companion. Because K2-39b has a short orbital period, its existence makes it seem unlikely that tidal destruction is wholly responsible for the differences in planet populations around subgiant and main-sequence stars. Future monitoring of the transits of this system may enable the detection of period decay and constrain the tidal dissipation rates of subgiant stars.

ABSTRACT
Direct Lyα imaging of intergalactic gas at

has recently revealed giant cosmological structures around quasars, e.g., the Slug Nebula. Despite their high luminosity, the detection rate of such systems in narrow-band and spectroscopic surveys is less than 10%, possibly encoding crucial information on the distribution of gas around quasars and the quasar emission properties. In this study, we use the MUSE integral-field instrument to perform a blind survey for giant

nebulae around 17 bright radio-quiet quasars at

that does not suffer from most of the limitations of previous surveys. After data reduction and analysis performed with specifically developed tools, we found that each quasar is surrounded by giant

nebulae with projected sizes larger than 100 physical kiloparsecs and, in some cases, extending up to 320 kpc. The circularly averaged surface brightness profiles of the nebulae appear to be very similar to each other despite their different morphologies and are consistent with power laws with slopes

. The similarity between the properties of all these nebulae and the Slug Nebula suggests a similar origin for all systems and that a large fraction of gas around bright quasars could be in a relatively “cold” (T ∼ 104 K) and dense phase. In addition, our results imply that such gas is ubiquitous within at least 50 kpc from bright quasars at

independently of the quasar emission opening angle, or extending up to 200 kpc for quasar isotropic emission.
