Authors: Mangmeechai Aweewan , Jirapornvaree Ittisak
Published: August 2019

This study aims to understand the factors affecting graduate study choices of ASEAN and international students in Thailand. Quantitative and qualitative methods were applied in this study. The result showed that majority of international students between 2013 - 2015 were Chinese while among the ASEAN, students from Myanmar, Cambodia, and Laos were the highest. Among 42 factors, the most influential factor was quality of teachers who influence the selection by international students and ASEAN students significantly at the 0.05 level. International students place an emphasis on politics and security, while ASEAN students focus on future career prospects after graduation. The development of Thailand’s competitiveness as an education hub in ASEAN is also possible. Thailand has the knowledge that is needed to enhance developing countries. It is recognized internationally for agriculture, public health, and education.

Authors: Dalbudak İbrahim , Çelik Serkan
Published: August 2019

This study was performed to investigate the characteristics of emotional intelligence and aggression between the students from Ege University Faculty of Sport Sciences and the students from the State Conservatory of Turkish Music. A total of 211 people (top-tier athletes and top-tier artists from Ege University) were selected for the study. Questionnaire method was used in the study. To evaluate the variables of the study, the revised Schutte Emotional Intelligence Scale that was adapted to Turkish by Tatar, Tok, and Saltukoğlu which consists of 41 items and the “Inventory of Aggression” that was developed by İpek İlter (Kiper) which consists of 30 items was used. In this study, the data set was analyzed in the package program SPSS 22.0 and the study was done using frequency tables, reliability analysis, unpaired t-test, one-way analysis of variance, Tukey’s test, and correlation analysis in the analyses. As a result, while a significant positive relationship between the emotional intelligence and the destructive and passive aggression was found (p0.05). We think that this is an important study because it helps us to be informed about the emotional intelligence and the aggression characteristics of the conservatory and sports sciences students and to make a serious contribution to the studies by conducting similar researches with different sample groups in different fields and different branches in different universities.

Promoting Peer Feedback in Developing Students’ English Writing Ability in L2 Writing Class
Authors: Kuyyogsuy Sirikarn
Published: August 2019

The study aimed at investigating the effects of peer feedback on students’ English writing ability in L2 writing class. A mixed-methods research, an embedded experimental design was employed, making use of a writing pretest and post-test and self-written reflection in the experiment. Data were quantitatively analyzed through a dependent simple t-test, and content was thematically analyzed for qualitative data. The participants were 21 undergraduate students majoring in English in the three southernmost border provinces of Thailand. The findings revealed that from the mean scores of the pretest and post-test, the students had made significant progress in their writing ability. Additionally, the effect size was calculated at 1.97, which means that its magnitude was “large”. Moreover, students reflected that peer feedback was a worthwhile experience for social interaction, and provided them with perceiving the writing process, developing affective strategies, supporting critical thinking skills, and developing socially and intellectually by means of working collaboratively. In addition, it helped them practice to become more autonomous learners. As a result, peer feedback should be implemented in L2 writing classes.

FACTORS INITIATING THE ACTIVATION OF FIRING CHAIN IN ARTILLERY FUSES
Authors: Krysinski Bogdan , Zych Piotr
Published: August 2019

Basic function of an artillery fuse is to ef-fectively initiate the activation of the main charge, located in the projectile shell, at a place and time decided by a gunner. The fuse also has a key role for ensuring the safe use of ammunition. Efficient initiation of the first part of so called firing train decides on proper functioning of the fuse. This element generates an impulse stimulating the activation of subsequent components of the train (chain). In the article, the authors will focus on factors initiating the correct activation of first components of the fire train in artillery fuses. These factors, with some pros and cons, will be discussed on examples of fuses which are used up to now.
The Productive Body
Authors: Schoonheim Liesbeth ,   DePaul University
Published: August 2019

This essay aims to correct the widely-held view that Arendt is hostile to the body due to its physical needs. By focusing on two modes of corporeality that are distinguished by the production of bodily substances—the digestive body and the crying body—I argue that Arendt (1) deployed various notions of corporeality that thematize, in different ways, the uncontrollability our bodies; and (2) argues for the affirmation of this unmasterablity because it corresponds to the conditioned nature of human existence. Firstly, Arendt criticized the Greek, narcissistic aspiration toward physical beauty, exemplified in the figure of Achilles, for its attempt to subjugate the digestive body to a preconceived end—a criticism that equally applies to Connolly’s plea for strategically altering our affects. Secondly, Arendt’s appreciation of Homer’s description of a crying Odysseus shows that the acknowledgment of events constitutive of one’s life consists in a publicly visible somatic reaction.
Including political context in the psychological analysis of collective action: Development and validation of a measurement scale for subjective political openness
Authors: Saavedra Patricio , Drury John
Published: August 2019

Sociological and Political Science research has argued that political conditions affect both the occurrence of protests and the actions protesters choose. However, an approach that considers people’s perceptions on these conditions is still absent in the social psychological literature. Subjective Political Openness (SPO) is a new construct which fills this gap by incorporating features of political context into the psychological analysis of protests. We propose that SPO comprises perceptions relating to three dimensions: government actions to allow/restrict protests, police measures to actively prevent them, and the extent that public opinion legitimizes protests. We conducted two studies in the UK and Chile to validate scales created for each proposed dimension, test their measurement invariance, establish SPO’s configuration, and demonstrate its convergent validity. Participants in Study 1 were university students (n UK = 203; n Chile = 237), whereas in Study 2 a general population sample from both countries was included (n UK = 377; n Chile = 309) with the purpose of generalizing the results. Both studies consistently showed that SPO is a multidimensional construct configured as a bifactor model comprising the dimensions associated with perceptions of the government and police actions to confront protests. Although we tested two different measurement scales for the perceived legitimacy given by public opinion to protests, results demonstrated this dimension is not part of SPO. The SPO configuration has implications for both our understanding of collective action and how we study it.

Authors: Fedota O. M. , Feskov O. M. , Zhylkova I. S.
Published: August 2019

Aim. The association of polymorphic variants of genes MTHFR (C677T, A1298C) and MTRR (A66G) with sperm aneuploidy in men with low reproductive function was investigated. Methods. SNPs determinations were performed by the real-time PCR technique. Sperm DNA fragmentation analysis was performed using the method of sperm chromatin dispersion. To detect aneuploidy in spermatozoa nuclei the method of fluorescent in situ hybridization (FISH) was used. Results. Polymorphic alleles in genes of folate metabolism are associated with sperm aneuploidy in men with low reproductive function. The link between the number of alternative alleles of polymorphic variants A1298C of MTHFR gene in genotype and the average level of aneuploidy in sperm chromosome 16 is proved.Conclusion. Aneuploid sperm is able to fertilize the oocytes, but the further formation of the blastocyst and embryo implantation may be blocked at various stages of development. Understanding the genetic basis of aneuploidy in sperm of men could reduce the reproductive losses in IVF practice.Keywords: DNA fragmentation, sperm aneuploidy, MTHFR, MTRR, reproductive function.

Authors: DEMİRKOL Nermin , DEMİRKOL Mehmet
Published: August 2019

Objectives: The aim of this study was to
evaluate the length and diameter properties of single dental implants that
posteriorly placed on the mandible and maxilla.

Materials and Methods: Two hundred ninety three
posterior single dental implants  were
evaluated in this retrospective study by same surgical procedure from 2010 to 2016
years. Demographics of patients, anatomic localizations, implant
characteristics (length and diameter), satisfaction of the patient and implant
loss were recorded. Implants that placed only single in posterior defect site
(premolar or molar) with limited by a natural tooth or a prosthetic restored
tooth on the either side of edentulous region were included. Visual analogue scale (VAS) was used
for the satisfaction of the patients. The descriptive statistical analysis
were done.

Results: A
total of 275 patients with 293 dental implants (139 male and 136 female),
ranging from 18 to 72 years (42.13 mean years) were analyzed.  The majority of the dental implants were
inserted mandible (156, 53.3%), 137 in maxilla (137, 46.7%). The first molar
region was the most implantation area, inserting with 181 (61.9%) implants, of
which 115 (39.3%) were in mandible, 66 (22.6%) in maxilla. The most frequent
implant diameter placed was the 4 mm (54, 18.4%) and 12 mm (94, 32%) was the
most frequent used implant length. Nine implants were failed and all success
rate was found to be 97%.

Conclusion: According
to these results, single dental
implants in the posterior region can be used safely with high success
rates.
Simmel: Bildung as the Form of Subjectivity
Authors: D’Andrea Fabio
Published: August 2019

This essay is composed of two parts: in the first I contend that Simmel was a representative of a cultural variant within Enlightenment modernity. Dumont has shown that there are several cultural variants born of the clash between former European traditional cultures and the modern set of universal values. This set and the variants are linked by a Wechselwirkung that modifies them all, thanks to the work of cross-representations. In the second part I argue that Simmel had German Bildung in mind when describing the shaping of subjectivity and the form of the life process and that Bildung is a cross-representation. As such it plays a major role in contemporary cultural processes which cannot be fully understood without appreciating its multidimensional complexity.
Pedagogical Implications of Simmel's Relativism. The Strasbourg Lectures on Pedagogy (1915-1916)
Authors: Amat Matthieu
Published: August 2019

Simmel's relativism aims to achieve the modern shift from substance to function without falling into pure sociological functionalism and generalized sceptical dissolution. This relativism would like to be at the same time a theory of objective forms of culture, a critique of modern forms of life and culture and a philosophical practice and attitude. That is why it is always both a philosophy of life and a philosophy of culture. Based on the pedagogy courses held by Simmel in Strasbourg in 1915/1916, this article outlines the consequences of this relativism in terms of pedagogy and philosophy of education. In particular, it considers ways to mitigate the "tragedy of culture", that is to promote the mobility and individuation of life without sacrificing the consistency of objective forms of culture.
Eros as Educator in the Era of Advanced Monetary Economy: Simmel’s Social Metaphysics of the Erotic Being
Authors: Christias Panagiotis
Published: August 2019

In the era of advanced monetary economy, the nexus of love, money, and good education is at the origin of the “good society”. If marriage was invented for reasons of administration of goods and money, then the fact that individual love came upon marriage in the specific historical and geographical context of the Western European metropolitan life cannot be a coincidence. The platonicladder of love, that leads to eternity through the erotic elevation of the soul to the sight of the Ideas, is transformed in Modern era through the new perception of Money as a “secular god”. For Plato, the goal of the lover is actually “education” (paideia) as he is supposed to give to the soul of the beloved wings in order to elevate itself to the contemplation of the Ideas. Plato’s heritance regarding love, says Simmel, is the belief that beyond the affect something of a bigger order is hiding in the phenomenon of love. As long as serial monogamy is the dominant model of erotic relations in our days, it is clear that its spiritual background is linked to Platonic Eros, not as an initiation to the science of the general, but, bended by the modern understanding of the individual, as an art of the individual. What is explored in this article is the educational role of Eros and its cultural potential.Eros can actually be considered as educator, as the initiator of the individual to a higher collective and spiritual order.
L’art des (petites) différences
Authors: Criton Pascale , Kanach Sharon
Published: August 2019

Dans cet entretien, la compositrice française Pascale Criton retrace les grandes lignes qui sous-tendent son écriture et sa pensée musicales. Passionnée par le continuum sonore, ses rencontres avec Ivan Wyschnegradsky, Gérard Grisey – mais aussi avec le philosophe Gilles Deleuze – dans le courant des années 1970, confirment son intérêt pour les micro-intervalles et la variabilité du son. La compositrice livre les enjeux qui mobilisent son attention au fil des oeuvres qui jalonnent son parcours, des années 1980 à aujourd’hui. L’idée d’interaction écosensible émerge avec l’emploi de scordaturas en 1/4, 1/12e et 1/16e de ton associées à la synthèse du son (Thymes, 1988), ou en référence à des comportements acoustiques (Artefact, 2001) qui renouvellent l’écriture du geste (Objectiles, 2002). Pascale Criton interroge aussi bien les techniques instrumentales que la notation et l’interprétation (Circle Process, 2012). Son utilisation des petites différences vise l’élargissement de la perception et s’étend aujourd’hui à une écoute sensible aux phénomènes acoustiques et perceptifs (Wander Steps, 2018).
Playing with Shadows: Reinjection Loops and Historical Allusion in Georg Friedrich Haas’s Live Electronic Music
Authors: Morrison Landon
Published: August 2019

Recent scholarship suggests that the music of Austrian composer Georg Friedrich Haas can be understood as a dramatic confrontation between “clashing harmonic systems” (Hasegawa, 2015). Building on this observation, the present article focuses on Haas’s recent endeavors in the genre of live electronic music, showing how the composer deploys a relatively straightforward technical procedure—the reinjection loop,orthe delayed playback of recorded sound at various speeds—to juxtapose different modes of pitch organization, including twelve-tone equal temperament, ultrachromatic microtonality, and just intonation. After surveying the composer’s relationship to these historical idioms, the article presents detailed analyses of two pieces (Ein Schattenspieland String Quartet No. 4) to illustrate how the reinjection loop operates at multiple registers simultaneously, bringing the performers into contact with their immediate past, while also bringing Haas into dialogue with the shadows of his own compositional predecessors.
Structural Neural Correlates of Impaired Postural Control in People with Secondary Progressive Multiple Sclerosis
Authors: Arpan Ishu , Fling Brett , Powers Katherine , Horak Fay B. , Spain Rebecca I.
Published: August 2019

Background:

Secondary progressive multiple sclerosis (SPMS) is characterized by worsening of postural control and brain atrophy. However, little is known about postural deficits and their neuroanatomical correlates in this population. We aimed to determine the neuroanatomical correlates of postural deficits in people with SPMS and whether posture control deteriorates concomitantly with the brain and spinal cord atrophy in 2 years in SPMS.

Methods:

This study is a post hoc analysis of data from 27 people with SPMS (mean ± SE age, 58.6 ± 1.1 years). Participants had magnetic resonance imaging (MRI) of the brain and cervical spinal cord followed by sway testing using inertial sensors during standing with eyes open (EO) and eyes closed without (EC) and with (ECC) a cognitive task. Partial correlations investigated relationships between postural control and MRI measures at baseline and 2 years.

Results:

At baseline, sway measures were inversely related to cortical thickness and cord cross-sectional area (CSA) during the EO task but only to cord CSA with EC (P < .05). After 2 years, the percentage change in sway amplitude and dispersion during EO tasks significantly related to the percentage decline in cord CSA (P < .01).

Conclusions:

Cortical and spinal cord inputs are essential for regulation of postural control during standing with EO in SPMS. Without visual input, people with SPMS preferentially rely on somatosensory inputs from the spinal cord for maintaining postural control. Postural deficits related to cord atrophy over 2 years, suggesting that postural control may be a surrogate marker of disease progression in people with SPMS.
Population response magnitude variation in inferotemporal cortex predicts image memorability
Authors: Jaegle Andrew , Mehrpour Vahid , Mohsenzadeh Yalda , Meyer Travis , Oliva Aude , Rust Nicole
Published: August 2019

Most accounts of image and object encoding in inferotemporal cortex (IT) focus on the distinct patterns of spikes that different images evoke across the IT population. By analyzing data collected from IT as monkeys performed a visual memory task, we demonstrate that variation in a complementary coding scheme, the magnitude of the population response, can largely account for how well images will be remembered. To investigate the origin of IT image memorability modulation, we probed convolutional neural network models trained to categorize objects. We found that, like the brain, different natural images evoked different magnitude responses from these networks, and in higher layers, larger magnitude responses were correlated with the images that humans and monkeys find most memorable. Together, these results suggest that variation in IT population response magnitude is a natural consequence of the optimizations required for visual processing, and that this variation has consequences for visual memory.
Evolution of asymmetric gamete signaling and suppressed recombination at the mating type locus
Authors: Hadjivasiliou Zena , Pomiankowski Andrew
Published: August 2019

The two partners required for sexual reproduction are rarely the same. This pattern extends to species which lack sexual dimorphism yet possess self-incompatible gametes determined at mating-type regions of suppressed recombination, likely precursors of sex chromosomes. Here we investigate the role of cellular signaling in the evolution of mating-types. We develop a model of ligand-receptor dynamics, and identify factors that determine the capacity of cells to send and receive signals. The model specifies conditions favoring the evolution of gametes producing ligand and receptor asymmetrically and shows how these are affected by recombination. When the recombination rate evolves, the conditions favoring asymmetric signaling also favor tight linkage of ligand and receptor loci in distinct linkage groups. These results suggest that selection for asymmetric gamete signaling could be the first step in the evolution of non-recombinant mating-type loci, paving the road for the evolution of anisogamy and sexes.
A structural mechanism for phosphorylation-dependent inactivation of the AP2 complex
Authors: Partlow Edward A , Baker Richard W , Beacham Gwendolyn M , Chappie Joshua S , Leschziner Andres E , Hollopeter Gunther
Published: August 2019

Endocytosis of transmembrane proteins is orchestrated by the AP2 clathrin adaptor complex. AP2 dwells in a closed, inactive state in the cytosol, but adopts an open, active conformation on the plasma membrane. Membrane-activated complexes are also phosphorylated, but the significance of this mark is debated. We recently proposed that NECAP negatively regulates AP2 by binding open and phosphorylated complexes (Beacham et al., 2018). Here, we report high-resolution cryo-EM structures of NECAP bound to phosphorylated AP2. The site of AP2 phosphorylation is directly coordinated by residues of the NECAP PHear domain that are predicted from genetic screens in C. elegans. Using membrane mimetics to generate conformationally open AP2, we find that a second domain of NECAP binds these complexes and cryo-EM reveals both domains of NECAP engaging closed, inactive AP2. Assays in vitro and in vivo confirm these domains cooperate to inactivate AP2. We propose that phosphorylation marks adaptors for inactivation.

Microorganisms in aerobic granules formed in sequencing batch reactors (SBR) remove contaminants, such as xenobiotics or dyes, from wastewater. The granules, however, are not stable over time, decreasing the removal of the pollutant. A better understanding of the granule formation and the dynamics of the microorganisms involved will help to optimize the removal of contaminants from wastewater in a SBR. Sequencing the 16S rRNA gene and internal transcribed spacer PCR amplicons revealed that during the acclimation phase the relative abundance ofAcinetobacterreached 70.8%. At the start of the granulation phase the relative abundance ofAgrobacteriumreached 35.9% and that ofDipodascus89.7% during the mature granule phase. Fluffy granules were detected on day 43. The granules with filamentous overgrowth were not stable and they lysed on day 46 resulting in biomass wash-out. It was found that the reactor operation strategy resulted in stable aerobic granules for 46 days. As the reactor operations remained the same from the mature granule phase to the end of the experiment, the disintegration of the granules after day 46 was due to changes in the microbial community structure and not by the reactor operation.

Published: August 2019

Aim: In a pot experiment the accumulation of zinc in Amaranthus caudatus and Corchorus olitorius from contaminated soil and its relevance for phytoextraction were studied.

Study Design: Plants were exposed to three levels of zinc concentration as zinc sulphate heptahydrate (0,150, 300, 450 ppm), laid in completely randomized design.

Place and Duration of Study: The study lasted for a total of 37 days in a housing facility used for phytoplankton culture at National Institute for Freshwater Fisheries Technology New-Bussa Nigeria.

Materials and Methods: Seeds were raised in a nursery for 16 days, and transplanted to pots containing each 2 kg of air-dried and sieved soil. Zinc was artificially applied to soil for each vegetable. They were watered at 60-70 % field capacity and growth parameters measured every 7 days. Plants were carefully uprooted after 3 weeks of transplanting, washed, and weighed before and after oven drying. They were analyzed for zinc concentration.

Results: Results of this study showed decreases in growth and yield at 300 and 450 ppm zinc concentrations. Plant height for both vegetables increased at 150 ppm however these increases were significantly different (P≤0.05) with control for Corchorus only. There were also significant differences (P≤0.05) between treatments in zinc accumulation. Results further showed that zinc was accumulated in the leaves more than the roots. Concentrations of zinc in plant tissues of both vegetables followed a similar order of leaves > roots > stem indicating their efficiency in zinc translocation from roots to leaves. Translocation factors were generally greater than unity.

Conclusion: Despite their lack of hyperaccumulation properties, both vegetables exhibited good potential for phytoextraction. The higher translocation factor of C. olitorius indicated better phytoextraction potential.

Aims: The aim of this research was to investigate the morphological characteristics of the pollen grain of some species of genus Allium.

Methodology: The pollen grains were examined by using Light Microscopy (LM), Scanning Electron Microscopy (SEM) and the pollen grains of one species under Transmission Electron Microscopy (TEM).

Results: The pollen grains were oblate and medium in shape and size. The pollen ornamentation of exine surface, exine ornamentation on sulcus edge, lumina number in the exine surface and the state of pollen grain apex in the examined species were different. Semitectate and columellate ectexine with discontinuous endexine were seen in the pollen wall structure (sporoderm). The dendrogram obtained from the pollen characters in SEM observations by using the numerical taxonomy system (NTSYS) software placed the studied species in two types.

Conclusion: Our palynological dendrogram can be used for segregation the sections and subgenera taxonomical levels in the studied species of genus Allium and confirmed the phylogram of the recent phylogenetic research.

Published: August 2019

The present study was undertaken to assess the differences in the level of spirituality and psychological well-being among institutionalized and non- institutionalized elderly (above 65 years of age) across gender. The study was based on the sample of 200 respondents: Institutionalized elderly (n1=100) drawn from the Society Registration Act (SRA) recognized old age homes of Uttarakhand through census method and equivalent sample of non-institutionalized elderly (n2=100) drawn through lottery method from the nearby localities adjacent to the old age homes. The level of spirituality and psychological well-being was assessed through standardized scales. The findings of the study revealed that females irrespective of residential setting were found to have higher levels of spirituality whereas males irrespective of residential setting were found to have significantly higher level of psychological well-being.

Prevention of Health Care‐Associated Infections
Authors: Sullivan Kaede V. , Pfaller Michael A. , Diekema Daniel J.
Published: December 2024

This chapter discusses the impact of health care‐associated infections (HAIs) on patient outcomes and health care costs and the organization of the hospital infection prevention program (IPP) and describes the important role that the clinical microbiology laboratory (CML) plays in HAI prevention. An HAI is an infection that is acquired in a hospital or health care facility. The incidence of HAIs involving staphylococci and enterococci increased as these organisms became increasingly resistant to antibiotics. The responsibilities of the hospital IPP include surveillance and prevention of HAIs, continuing education of medical staff, outbreak control, protection of employees and visitors from infection, and providing advice on introduction of new products and procedures. The development and application of new technologies in the CML can greatly enhance infection prevention efforts. Close collaboration between CML and personnel from infection prevention and antimicrobial stewardship programs is required to ensure optimal HAI prevention, which saves money and lives.
Streptococcus

Published: December 2024

This chapter focuses on well‐known and novel streptococcal species found in human specimens and covers changes that were applied to the taxonomy of streptococci in recent years. Streptococci can cause infections in humans and in many animal species, including mammals and fish. Transmission of streptococcal infections occurs by various routes. Pathogenic species such as
S. pyogenes
and
S.pneumoniae
, which colonize the upper respiratory tract, are primarily transmitted through direct contact or droplets.
S. agalactiae
transmission from mother to child can occur during birth and within the first seven days of life. Human beta‐hemolytic group C and group G streptococci are defined as
S. dysgalactiae subsp. equisimilis
, while group C and L streptococcal animal isolates are classified as
S. dysgalactiae subsp. dysgalactiae
.
S. mutans
and
S. sobrinus
belong to the S. mutans group.
Listeria
and
Erysipelothrix
Authors: Smith Kenneth P. , Harris Rebecca M.
Published: December 2024

Listeria
and
Erysipelothrix
are genera of small, non‐sporeforming, Gram‐positive bacilli that include the opportunistic human pathogens
Listeria monocytogenes
and
Erysipelothrix rhusiopathiae
. The clinical presentation of an individual exposed to
Listeria
varies from asymptomatic to mild gastroenteritis to life‐threatening illness, depending on a combination of factors that include bacterial virulence, inoculum size, and underlying host defenses. Isolation of
Listeria
can be achieved from clinical specimens from normally sterile sites, including blood and cerebrospinal fluid. Typing of
Erysipelothrix
is used for the analysis of outbreaks in farmed animals and other epidemiologic purposes but has little clinical relevance in humans. Historically, strain typing was performed by serologic testing based on somatic and flagellar antigens. Due to the lack of resistant strains, breakpoints exist for susceptible results only.
Mycobacterium
: General Characteristics, Laboratory Processing, Staining, Isolation, and Detection Procedures
Authors: Martin Isabella , Pfyffer Gaby E. , Parrish Nicole
Published: December 2024

The genus
Mycobacterium
encompasses several prominent pathogenic species, most notably the members of the
Mycobacterium tuberculosis
complex,
Mycobacterium leprae
, and
Mycobacterium ulcerans
. Continued use of the single genus and long‐standing taxonomy will provide laboratorians and clinicians with a standardized approach for assessment of patients with mycobacterial disease and/or colonization that will result in fewer errors while conserving often limited and valuable resources. The sensitivity and time to growth detection of the
Mycobacterium
Growth Indicator Tube system are superior to that of solid media in clinical evaluations. With the advent of molecular techniques designed for molecular epidemiology, cross‐contamination linked either to laboratory procedures or, more rarely, to contaminated bronchoscopes can easily be proven. Quality control (QC) is vital for monitoring a laboratory's effectiveness in detecting and isolating mycobacteria. This includes standard components of laboratory quality assurance, such as personnel competency, procedure manuals, external proficiency testing, and QC of media, tests, and reagents.
Estimation of heart dose in left breast cancer radiotherapy: Assessment of vDIBH feasibility using the supervised machine learning algorithm
Authors: Rajurkar Shriram Ashok , Verma Teerthraj , Gupta Rajeev
Published: December 2024

Background and objective

The volunteer deep inspiration breath hold (vDIBH) technique is used to reduce the heart dose in left breast cancer radiotherapy. Many times, it is faced that despite rigorous exercise and training, not all patients get benefited as expected. The primary objective of this study was to develop a machine learning program for prediction of mean heart dose before left breast radiotherapy under vDIBH.

Methods

The present work is based on the dosimetric parameters of eighty‐two left breast cancer patients, who have undergone modified radical mastectomy, enrolled for their radiation treatment. The trained machine learning algorithm employed linear regression to establish a correlation between Haller Index and heart mean dose (HMD) received during the ca left breast cancer radiotherapy. Subsequently, HMD values were used to model the regression relationship with maximum heart distance (MHD).

Results

The method adopted is beneficial in patient selection and assessment for suitability of patients’ radiotherapy planning under vDIBH treatment technique. For data from 21 test patients, the mean of HMD obtained from the treatment planning system (TPS) and the mean of predicted HMD by developed program were found to be 468.76 cGy and 464.66 cGy, respectively.

Conclusion

The present work facilitates precise HMD prediction in left breast cancer radiation therapy even before starting the treatment planning process. Additionally, this program offers suggestions in terms of modifications in treatment settings for even better results of vDIBH techniques if not matches with the anticipated results.
