The cellulose--lignin balance affects the twisted growth of Yunnan pine trunk
Authors: cui kai , Liu Zirui , Li Jin , Gao Chengjie , Miao Yingchun
Published: October 2022

It is a debate whether trunk twisting belongs to environmental
alteration or genetic variation. Through a diallel cross experiment, we
first determined that trunk twisting of Yunnan pines was controlled by
recessive genes. Anatomical analysis identified that straight and twisty
types differed in xylem and phloem. RNA-seq of materials enriched by
laser microdissection revealed three genes involved in auxin signal
transduction, photosynthesis, and sucrose metabolism, namely ARF,
POR, and CBH. These genes were co-expressed at different
growth stages of twisty types, and among them, ARF is crucial
regulating trunk twisting formation. The enzyme activities involved in
sucrose metabolism, carbon fixation, and glycolysis were significantly
increased after exogenous auxin was added to twisty types. When auxin
signal transduction inhibitor (auxinole) and transport inhibitor (TIBA)
were added, the plant height and related pathways were more obviously
reduced in straight types. ARF can not only downregulate
POR to block chlorophyll synthesis but also allows abundant
sucrose to synthesize cellulose. Nevertheless, due to downregulated
CBH expression and abnormal cellulolysis, cellulose accumulates
and the lignin content decreases, eventually making the trunk highly
prone to twisted growth. This study suggests that ARF can be
vital in trunk shape screening during the early growth of Yunnan pines.
Comparison of Machine Learning Techniques for Precision in measurement of glucose level in Artificial Pancreas
Authors: Nilam * , Yadav Vijay K.
Published: October 2022

Precision in measurement of glucose level in artificial pancreas is a
challenging task and mandatory requirement for the proper functioning of
artificial pancreas. A suitable machine learning technique for the
measurement of glucose level in artificial pancreas may play crucial
role in the management of diabetes. Therefore in the present work, a
comparison has been made among few machine learning (ML) techniques for
measurement of glucose levels in artificial pancreas because the machine
learning is an astounding technology of artificial intelligence, and
widely applicable in various fields such as medical science, robotics,
environmental science, etc. The models namely decision tree (DT), random
forest (RF), support vector machine (SVM), and K-nearest neighbours
(KNN), based on supervised learning, are proposed for the dataset of
Pima Indian to predict and classify the diabetes mellitus. Ensuring the
predictions and accuracy up to the level of DMT2, the comparative
behavior of all four models has been discussed. The machine learning
models developed here stratifies and predicts whether an individual is
diabetic or not based on the features available in the data set. Dataset
passes through pre-processing and machine learning algorithms are fitted
to train the dataset, and then the performance of the test results has
been discussed. Error matrix (EM) has been generated to measure the
accuracy score of the models. The accuracies in prediction and
classification of DMT2 models are 71%, 77%, 78%, and 80% for DT,
SVM, RF and KNN algorithms respectively. The KNN model has shown a more
precise result in comparison to other models. The proposed methods have
shown astounding behaviour in terms of accuracy in the prediction of
diabetes mellitus as compared to previously developed methods.
Enhanced β-Glucosidase in western flower thrips affects its interaction with the redox-based strategies of kidney beans under elevated CO 2
Authors: Liu Xiaowei , Wang Yanhui , Liu Hui , Huang Xinyi , Qian Lei , Yang Baoqing , Xu Yujing , Chen Fajun
Published: October 2022

β-Glucosidase is validated as an elicitor for early immune responses in
plants and it was detected in the salivary glands of Frankliniella
occidentalis in previous research. Seven differentially expressed genes
encoding β-Glucosidase were obtained by comparing the transcriptomes of
F. occidentalis adults grown under two different CO
concentrations (800 ppm vs. 400 ppm), which might be
associated with the differences in the interaction between F.
occidentalis adults and its host plant, Phaseolus vulgaris under
different CO levels. To verify this speculation,
changes in defense responses based on the production and elimination of
reactive oxygen species (ROS) in P. vulgaris leaves treated with
three levels of β-Glucosidase activity under ambient CO
(aCO ) and elevated CO
(eCO ) were measured in this study.
The results showed that both leaves infested with thrips and those
sprayed with the pure β-Glucosidase solution showed significant
increases in ROS levels under aCO and eCO
, and the activities of antioxidant enzymes including
superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) were
increased correspondingly, while in leaves infested with
FoβGlu-1-silenced thrips, the ROS levels and activities of these
enzymes did not change significantly during the first 12 hours of injury
regardless of CO level. Besides, significantly higher
levels of ROS and lower activities of SOD, POD and CAT in injured leaves
under eCO compared to aCO were
noticed, which would negatively affect P. vulgaris leaves and
facilitate thrips damage.
Mechanism for dissociative hydrolysis of pyrimidine nucleoside d4N: inversion vs retention
Authors: Zeng Yi , Zhao Yuexin , Zhang Wei , Jiang Yang
Published: October 2022

Employing the microhydration model that involves two to five explicit
water molecules, two plausible dissociative hydrolysis pathways of
2’,3’-didehydro-2’,3’-dideoxyuridine (d4U), α-path with
configuration-inversion and β-path with configuration-retention, have
been investigated by M06-2X(CPCM)/6-31++G(d,p) method. Using this model,
inclusion of three explicit water molecules (n=3) is shown to be the
smallest system that gives the minimal activation free energy for α-path
and β-path. Our results suggest that the glycoside cleavage is the RDS,
and α-path is more favorable kinetically than β-path. Whereas β-path
with exergonic formation of β-dihydrofuran-like sugar with keto
pyrimidine complex possesses thermodynamic preference over α-path, where
the formation of α-dihydrofuran-like sugar with enol pyrimidine complex
is endergonic. The free energy barriers of RDSs for d4U (24.8 kcal
mol) and d4T (27.3 kcal mol)
suggest that the glycosidic bond in d4T is more stable than that in d4U.
The relative lower stability of d4U is probably an important factor for
less antiviral activity of d4U. The small free energy barrier
differences of ~1 kcal mol for
β-path over α-path, and the reaction free energy differences of
~ -12 kcal mol for β-path lower than
α-path in d4T and d4U suggest a competitive β-path in pyrimidine d4Ns.
The higher free energy barriers of RDSs in ddU (27.6 kcal
mol) and ddT (29.0 kcal mol)
indicate that the saturated sugar moiety increases the stability of
glycosidic bond in contrast to the unsaturated counter parts in d4U and
d4T. NBO analysis also shows the kinetic preference of α-path over
β-path. Our results provide an exploration for the less antiviral
activity of d4U and the influence of saturated ribose on the glycosidic
bond stability of pyrimidine d4Ns.

Authors: Lu Pan , Li Yuanyuan , Mao Xiaobo , Chen Manhua
Published: October 2022

The LAmbre occluder is more convenient to operate than other left atrial
appendage closures(LAAC), and it can adapt to different anatomy of left
atrial appendage. However, some studies showed that Lambre occluder had
a higher incidence of device-related thrombus(DRT). This meta-analysis
aims to compare the safety and efficacy of the LAmbre occluder with
other LAAC devices. Eligible studies were retrieved from PubMed, Embase
and the Cochrane Library up to 1 July 2022 and reported the results.
Five studies of a total of 607 patients were included in the
meta-analysis. The LAmbre occluder was associated with higher rate of
DRT(OR [95% CI] = 5.25 [1.21, 22.86], P =0.03; I2=0%). No
significant differences were observed in the incidence of
procedure-related death, pericardial effusion, chest pain, bleeding and
vessel complication, contrast medium, fluoroscopy time ,death, stroke,
bleeding events, systemic embolism and peri-device leakage. In
conclusion, the LAmbre occluder had higher incidence of DRT than other
LAAC devices, and there were no significant differences in stroke,
bleeding events, and mortality.

Influence of snow and meteorological conditions on snow-avalanche deposit volumes and consequences for road-network vulnerability
Authors: KERN Hippolyte , Jomelli V. , Eckert Nicolas , Grancher Delphine , Deschatres Michael , Arnaud-Fassetta Gilles
Published: October 2022

Snow avalanches are a major component of the mountain cryosphere that
frequently create a menace for the road network. Deposit characteristics
determine the extent of damage and disruption to communication networks,
but the factors controlling snow-deposit volumes remain largely unknown.
This study investigates the influence of meteorological and snowpack
conditions on snow-avalanche deposits and road-network vulnerability
based on 1986 deposit volumes from 182 paths located in two regions of
the French Alps between 2003 and 2017: Guil and Haute-Maurienne valleys.
During the period, 195 avalanches impacted the road network in these
areas, leading to major disruptions. In Haute-Maurienne, correlations
between deposit volumes and meteorological and snowpack conditions are
high in winter. However, the relationships differ with path elevation
and orientation. Results do not show any significant relationship
between volumes and meteorological or snowpack conditions for the spring
season. Focusing on deposits that disturbed the road network, winter and
spring reveal a distinct influence of meteorological and snow variables
compared to the overall data set, with snowfall intensity as the
predominant control variable of deposit volumes leading to road cuts.
When the same analysis is conducted by considering Guil valley
separately or by aggregating Haute-Maurienne with Guil valley area data,
results do not show any significant relationship, highlighting the
specific regional nature of relations between deposit volumes and
meteorological and snowpack conditions.
Sentimental tourism as a means of national memory reviving
Authors: Sokolova Sofiia
Published: October 2022

The purpose of the article is to substantiate the importance of the development of sentimental tourism as a means of resuscitating of the national memory destroyed among a large number of Ukrainians during the Soviet era. The article presents an analysis of tourism in terms of its sentimental function – focused on the acquaintance with the biographical places of the repressed family member. An example of a tourist travel route is given, which has an emotional content, because it represents certain stages of the life of a relative shot in Stalin’s time. The research methodology includes mainly two methods – sources analysis and example description. The basic concepts have been defined and references to the history of the visited territories have been provided. The method of functional analysis has been used to characterize sentimental tourism. The theoretical conclusion has been made from own observations during the organization and implementation of tourism educational projects.
Development and application of a novel mass spectrometry ionization source for biological chemistry
Authors:   , Owen Rhodri N.
Published: October 2022

Since its development, electrospray ionization (ESI) for the analysis of thermally labile, polar compounds and particularly biomolecules has been extremely useful. Not all compounds can be easily protonated and electron ionization (EI) is still a widely used ionization method for compounds like hydrocarbons. However, the low-pressure environment of the EI source requires complex and expensive vacuum systems and inlets. Therefore, a source which can ionises non-polar compounds while operating at atmospheric pressure would be highly advantageous. In this thesis I have undertaken development and characterisation of four prototype atmospheric pressure glow discharge ionization sources for the analysis of compounds not normally amiable to ionization by conventional atmospheric pressure ionization sources. A helium micro-glow discharge source (“Prototype V”) operated using a direct current power supply was studied and its discharge characterised. Its current-voltage relationship increased linearly which is typical of the abnormal glow regime while thermal imaging showed it had a “cold” discharge. Prototype V was successfully interfaced with a Xevo G2-S time-of-ﬂight and a Xevo TQ-S triple quadrupole (Waters Corp, Wilmslow, UK) and used with a range of sample introduction methods, initially a solids probe, but later APCI and ESI probes. These probes enabled prototype V to readily integrate with separation sciences; speciﬁcally liquid chromatography was demonstrated for complex mixture analysis. Prototype V exhibited high analytical sensitivity in the nanogram range in both positive and negative modes and could ionize a wide range of compound chemistries from polar to non-polar. In particular it showed sensitivity to non-polar compounds in negative-ion mode when compared to ESI. This gives the source the potential to operate in conjunction with a range of sample inlets and in combination with other ionization techniques as part of a multimodal platform to analyse the widest range of samples and a step towards a universal source.
Investigating the factors influencing consumer adoption of social commerce in the context of Bangladesh
Authors:   , Sarker Prianka
Published: October 2022

The popularity of social media as a useful tool for socialisation and information exchange has resulted in a new type of electronic commerce known as social commerce. The rapid expansion of social media arouses the interest of many e-retailers to enlarge their company by taking advantage of social technology and services. Social commerce has gone mainstream among marketers, businesses, and scholars in recent years. Many countries, including the United Kingdom, United States, China, and South Korea, have already implemented the social shopping system. However, consumers in developing countries like Bangladesh are slower to accept social commerce. Despite the hype around this technology, no previous research specifically looked at consumer adoption of social commerce in the context of Bangladesh in a systematic manner. Given that, this research aims to “develop and empirically validate a conceptual model for understanding factors influencing consumer adoption and usage of social commerce in the context of Bangladesh”. The literature review of social commerce yielded a number of theoretical and methodological inadequacies. Therefore, this research assessed alternative models and theories in selecting the most suitable paradigm for this research. This study adapted Meta-UTAUT as a core theory to investigate consumer adoption of social commerce. For the extension of Meta-UTAUT, a further assessment was undertaken to determine appropriateness of additional constructs such as trust, social support, anxiety, grievance redressal, innovativeness, and continuous participation intention. This study collected the data (n=402) from social commerce users of Bangladesh using survey method in order to test and validate the research model. A total of twelve hypotheses were tasted using SPSS v.28. and AMOS v.28 based structural equation modelling. The results revealed that performance expectancy, effort expectancy, Innovativeness and Trust indirectly influence behavioural intention through attitude. Social influence and grievance redressal have a direct impact on behavioural intention. While facilitating conditions, social support, anxiety, and behavioural intention significantly influence usage behaviour. Finally, usage behaviour found to be a strong predictor of continuous participation intention. This research contributes to the knowledge through adoption and validation of a new consumer adoption theory and the role of anxiety and grievance redressal, which are new additions in the social commerce field.
The implications of costly airflows for space-use and movement decisions in birds
Authors:   , Lempidakis Emmanouil
Published: October 2022

The behavioural ecology of flight has largely considered how birds respond to mean flow conditions, but it is the gusty or extreme airflows that are likely to be particularly challenging. This thesis addresses this, examining the strategies birds use to negotiate turbulence over land, and exceedingly strong winds at sea. I first develop a method for sensing turbulence at fine scales using data collected onboard the animals themselves, taking homing pigeons (Columba livia) as model flapping fliers. Fine scale variation in the flight altitude and body displacement emerged as effective proxies of turbulence. I then assess the impact of freestream turbulence on flapping fliers and find that pigeons adapted their wingbeat kinematics (frequency and amplitude) to increase their flight stability in response to turbulence, but did so without a clear increase in flight effort. In my final two chapters I examine the responses of two seabird species to strong winds, first at sea, and then on land. Specifically, I investigate how streaked shearwaters (Calonectris leucomelas) respond to tropical cyclones, and how common guillemots (Uria aalge) select their breeding cliffs in relation to airflow conditions. I find that shearwaters fly towards the eye of the storm. This tendency increases with cyclone intensity and may enable birds to avoid strong onshore winds and reduce the associated risks of forced landings and/ or injury. Finally, computational fluid dynamics models reveal that guillemots select breeding cliffs that are sheltered from wind and storm conditions, rather than from the mean wind alone, or heat stress. This model of habitat selection could also predict habitat use across islands. Overall, this highlights the varied and sometimes surprising capacities of birds to cope with extreme and variable airflows and operate in areas that are, as yet, inaccessible to aircraft.

Published: October 2022

Kejadian longsor yang dipicu oleh hujan sangat berkaitan erat dengan intensitas dan durasi hujan. Informasi waktu terjadinya longsor memerlukan rekaman curah hujan yang akurat melalui pengukuran di lokasi longsor. Namun, seringkali rekaman curah hujan tidak diperoleh di area longsor. Naskah ini menyajikan hasil kajian curah hujan hasil pengukuran di stasiun hujan permukaan (ground station) dan pengukuran satelit. Penelitian bertujuan mengkaji hubungan data curah hujan hasil pengukuran dengan rain gauge (RG) dengan data hujan satelit Tropical Rainfall Masuring Mission (TRMM) dan Global Precipitation Measurement (GPM). Lokasi kajian berada di Kalibawang yang berada pada koordinat 7o40’33”LS/110o15’49”BT. Hasil kajian menyimpulkan bahwa hubungan antara rain gauge dengan data satelit termasuk dalam kategori sedang dengan nilai korelasi dari 0,50 hingga 0,55. Data satelit memiliki performa yang lebih baik dalam pengukuran curah hujan dibandingkan pengukuran curah hujan langsung di lapangan karena intensitas TRMM > intensitas GPM > intensitas rain gauge.

İnsan beslenmesindeki ilk kullanımı çok eski dönemlere dayanan alglerin besin takviyesi olarak kullanımı son yıllarda artış göstermiştir. Özellikle Spirulina en çok tüketilen mikroalg cinslerinden biridir. Spirulina hap, tablet, kapsül, toz ve jel formlarında besin takviyesi olarak kullanılmasının yanı sıra besin değerini arttırmak ve sağlık etkilerinden yararlanmak için çeşitli gıda ürünlerine eklenmektedir. Literatürdeki güncel veriler Spirulina’nın obezite, tip 2 diyabet gibi hastalıklar üzerinde olumlu etkileri olabileceğini göstermektedir. Spirulina’nın bu olumlu etkileri besin ögesi içeriği ve antioksidan ve anti-inflamatuvar aktivitelere sahip biyoaktif bileşen içeriği ile ilişkilidir. Olumlu sağlık etkilerinin yanı sıra Spirulina’yı besin takviyesi olarak kullanmanın bazı potansiyel riskleri bulunmaktadır. Bazı çalışmalarda Spirulina takviyelerinde ağır metal, siyanotoksin ve polisiklik aromatik hidrokarbonlar tespit edilmiştir. Bu derlemenin amacı, Spirulina’nın sağlık üzerine olumlu etkileri ve potansiyel risklerine ilişkin özelliklerini irdelemektir.

Nadir şekerler, alternatif tatlandırıcılar olarak sağlık açısından oldukça faydalı olmaları ve endüstriyel açıdan ekonomik değerlerinin yüksek olmaları sebebiyle büyük ilgi görmektedir. Nadir şekerlerin doğada çok sınırlı miktarlarda bulunması, bitkilerden elde edilen yaygın şekerlerin enzimatik, kimyasal veya diğer yollarla nadir şekerlere dönüştürülmesine yönelik çalışmaları teşvik etmiştir. Nadir şekerler arasında çok önemli bir yere sahip olan D-alluloz, sakkaroza çok yakın bir tatlılığa sahip olması ve düşük kalorisi ile dikkat çeken bir şekerdir. Kandaki glikoz seviyesini düşürme, insülin direncini iyileştirme, vücuttaki yağ birikimini azaltma ve ateş düşürme gibi birçok biyolojik fonksiyonu düzenleme özelliğine sahip olması, bunun yanı sıra, yüksek çözünürlüğe ve gıda dokusu üzerinde olumlu etkilere sahip olması, bu şekerin gıda işlemede kullanımını daha cazip hale getirmektedir. D-alluloz "sindirilemeyen karbonhidrat" olarak bilinmektedir. Birçok meyve ve içecekte ve bazı tahıl ürünlerinde doğal olarak bulunmaktadır. Günümüzde D-alluloz, bitkiden ekstraksiyon, kimyasal sentez, enzimatik dönüşüm gibi birçok yöntemle üretilebilmekte ve bazı gıda maddelerinin üretiminde güvenle kullanılabilmektedir. Bu derlemede, günümüze kadar geliştirilmiş ve uygulanmış olan D-alluloz üretim yöntemleri açıklanmış, bu yöntemler arasındaki farklar ve birbirlerine göre avantajları ve dezavantajları tartışılmıştır.

Stabilizerler, dondurma üretiminde arzu edilen viskozitenin ve hacim artışının sağlanması, dondurma tekstürü ve erime niteliklerinin iyileştirilmesi ve depolama esnasında rekristalizasyonun engellenerek raf ömrünün uzatılması amacıyla kullanılan ticari maddelerdir. Günümüzde farklı kaynaklardan elde edilen stabilizer maddelerin endüstriye kazandırılmasına yönelik yapılan çalışmalara gün geçtikçe yenisi eklenmektedir. Bu çalışmada dondurma teknolojisinde kullanılmakta olan stabilizerlerin yanı sıra stabilizer olma potansiyeli bulunan; fesleğen tohumu sakızı, ayva çekirdeği ekstraktı tozu, chia tohum jeli, mikrobiyal ekzopolisakkaritler, farklı kaynaklardan elde edilen selüloz türevleri gibi alternatiflerin dondurma üretimindeki kullanım olanakları derlenmiştir. Potansiyel stabilizer madde olarak görülen bu bileşenlerin, dondurma nitelikleri üzerine etkileri ve diğer stabilizerler ile olan sinerjik etkilerinden bahsedilerek endüstriyel kullanım olanakları değerlendirilmiştir.

Published: October 2022

OBJECTIVE

African Horse Sickness (AHS) is a vector-borne disease endemic to sub-Saharan Africa caused by African Horse Sickness Virus (AHVS). Infections in naïve horses have high morbidity and mortality rates. AHS pathogenesis is not well understood; neither the hematologic changes nor acute phase response occurring during infection has been fully evaluated. The study’s objective was to characterize the hematologic changes and acute phase response during experimental infection with AHSV.

ANIMALS

4 horses negative for AHSV group-specific antibodies.

PROCEDURES

In this prospective, longitudinal study conducted between November 23 and December 2, 2020, horses were experimentally infected with AHSV, and blood samples were obtained before inoculation and then every 12 hours until euthanasia. Hematologic changes and changes for serum amyloid A (SAA) and iron concentration were evaluated over time using a general linear model including natural logarithm of sampling time.

RESULTS

All horses were humanely euthanized due to severe clinical signs typical of AHS. Median Hct increased significantly, and the median WBC count, monocyte count, eosinophil count, and myeloperoxidase index changed significantly in all horses over time. Horses developed marked thrombocytopenia (median, 48 X 103 cells/µL; range, 21 X 103 to 58 X 103 cells/µL) while markers of platelet activation also changed significantly. Median SAA increased and serum iron concentration decreased significantly over time.

CLINICAL RELEVANCE

Results indicated severe thrombocytopenia with platelet activation occurs during infection with AHSV. Changes in acute phase reactants SAA and iron, while significant, were unexpectedly mild and might not be useful clinical markers.
