Authors: Amin Md. Tanzilul , Hasan Mahmud , Bhuiya N. M. Mahmudul Alam 
Published: September 2021

Objective: This study aimed to assess the prevalence, onset, and duration of COVID-19 associated symptoms, hospitalization, and recovery time from the infection in Bangladesh.Methods: A retrospective study was designed adopting the snowball sampling technique (n = 439). The association of gender, age, and comorbidity on COVID-19 associated complications was determined using chi-square and binary logistic regression analysis (p &lt; 0.05).Result: Fever, exhaustion, cough, loss of taste, sore throat, body ache, and hair-loss were prevalent among more than 50% of the participants and developed within fourth days in above 90% of the patients. Shortness of breath was significantly higher in males (χ2 = 5.671; OR 1.641). Significant comorbidity association on the shortness of breath (χ2 = 40.119; OR 2.564), vomiting (χ2 = 4.422; OR 1.018), and loss of speech (χ2 = 17.299; OR 3.430) was observed. Patients (&gt;40 years) exerted higher association in shortness of breath (χ2 = 24.083; OR 2.901). Age and comorbidity were significantly associated with COVID-19 associated hospitalization (χ2 = 16.890 and χ2 = 23.638, respectively) and recovery time (χ2 = 12.870 and χ2 = 26.924, respectively).Conclusion: The study suggests that the hospitalization rate increased for older (&gt;40 years) and comorbid patients. Comorbid patients demonstrated higher susceptibility to have shortness of breath, vomiting, loss of speech, and confusion, whereas male patients showed significant increase in the prevalence of sore throat, loss of smell, and vomiting compared to female patients.

Objective: To compare the EuroQol-5D-3L (EQ-5D-3L) and the Short Form-6D (SF-6D) utility scores in family caregivers (FCs) of colorectal cancer (CRC) patients.Method: This study was performed on FCs of CRC patients from three primary cancer centers in the capital city of the Heilongjiang province. The participants (FCs) who were enrolled, filled the EQ-5D-3L, along with the SF-6D questionnaire. Two tools were compared for their distribution, discriminant validity, agreement, and convergent validity along with known-groups validity.Result: Two hundred ninety-two FCs of CRC patients were enrolled. The score distribution of the SF-6D along with the EQ-5D-3L were not normal. A ceiling impact was seen in 31.8% of the FCs for EQ-5D-3L; however, none for the SF-6D. Good associations (Spearman’s rho = 0.622, p &lt; 0.01) and intraclass correlation coefficient (ICC 0.637 and average ICC 0.778) between the two scores were observed. The EQ-5D-3L yielded higher utility scores in contrast with the SF-6D in the better health subclass. The SF-6D distinguished better between excellent and good health statuses, with better effect size and relative efficiency statistics. Both tools showed good known-groups validity.Conclusion: The utility scores of SF-6D were remarkably lower relative to that of the EQ-5D-3L, but the difference may be clinically insignificant. However, the SF-6D may be superior because of the lack of ceiling impact. SF-6D exhibited a better convergent validity along with discrimination validity of excellent health condition and improved known-groups validity efficiency.

Published: September 2021

Background: Previous epidemiological studies have confirmed non-human primates (NHPs) as reservoirs for Cryptosporidium spp. , Giardia intestinalis, and Enterocytozoon bieneusi. It highlights the possibility of interspecies transmission between humans and macaques in laboratory animal facilities. This study aimed to investigate the prevalence of pathogenic intestinal protozoan infections in macaques and humans and to determine the risk of cross-species transmission from One Health view.Materials and Methods: A total of 360 fecal samples, including 310 from the four Macaca mulatta groups, 25 from the facility workers in a laboratory animal facility, and 25 from the villagers nearby in Yongfu country, southeast China, were collected. Nested PCR assays were done for detecting protozoan pathogens from all the specimens. Furthermore, potential risk factors (gender, age, and direct contact) on the occurrence of intestinal protozoa infection among different sub-groups were evaluated. A phylogenetic and haplotype network analysis was conducted to examine the genetic structure and shared patterns of E. bieneusi and Cyclospora cayetanensis.Results: The pathogenic intestinal protozoa were detected in both human and macaque fecal samples. A total of 134 (37.2%) samples were tested positive, which included 113 (36.4%) macaques, 14 (56.0%) facility workers, and 7 (28.0%) villagers, respectively. There was no significant difference in four intestinal protozoa infections between facility workers and villagers (χ2 = 2.4, P &gt; 0.05). However, the positive rate of pathogenic intestinal protozoa in the facility workers, who had direct contact with macaques, was significantly higher [odds ratio (OR) = 0.31, 95% confidence interval (CI): 0.09–1.00, P &lt; 0.05).Thirty-three ITS genotypes of E. bieneusi were identified, including five known genotypes (PigEBITS7, Peru8, Henan V, D, and CM1) and six novel genotypes (MEB1–6). Seven haplotypes were identified in the network analysis from C. cayetanensis-positive samples. Meanwhile, a phylogenetic and haplotype analysis confirmed the presence of zoonotic subtypes in NHPs and humans.Conclusion: The data collected from this study confirmed a high prevalence of intestinal protozoan infection in humans and macaques. These results warrant workers of such facilities and residents to limit contact with infected animals in order to minimize related health risks. The need for comprehensive strategies to mitigate the risk of zoonotic transmission, especially from a One Health perspective, is recommended.
Lineage-Specific Variation in IR Boundary Shift Events, Inversions, and Substitution Rates among Caprifoliaceae s.l. (Dipsacales) Plastomes

Published: September 2021

Caprifoliaceae s.l. plastid genomes (plastomes) show that one inversion and two inverted repeat boundary shifts occurred in the common ancestor of this family, after which the plastomes are generally conserved. This study reports plastome sequences of five additional species, Fedia cornucopiae, Valeriana fauriei, and Valerianella locusta from the subfamily Valerianoideae, as well as Dipsacus japonicus and Scabiosa comosa from the subfamily Dipsacoideae. Combined with the published plastomes, these plastomes provide new insights into the structural evolution of plastomes within the family. Moreover, the three plastomes from the subfamily Valerianoideae exhibited accelerated nucleotide substitution rates, particularly at synonymous sites, across the family. The patterns of accD sequence divergence in the family are dynamic with structural changes, including interruption of the conserved domain and increases in nonsynonymous substitution rates. In particular, the Valeriana accD gene harbors a large insertion of amino acid repeat (AAR) motifs, and intraspecific polymorphism with a variable number of AARs in the Valeriana accD gene was detected. We found a correlation between intron losses and increased ratios of nonsynonymous to synonymous substitution rates in the clpP gene with intensified positive selection. In addition, two Dipsacoideae plastomes revealed the loss of the plastid-encoded rps15, and a potential functional gene transfer to the nucleus was confirmed.

Coccoid cyanobacteria produce a great variety of secondary metabolites, which may have useful properties, such as antibacterial, antiviral, anticoagulant or anticancer activities. These cyanobacterial metabolites have high ecological significance, and they could be considered responsible for the widespread occurrence of these microorganisms. Considering the great benefit derived from the identification of competent cyanobacteria for the extraction of bioactive compounds, two strains of picocyanobacteria (coccoid cyanobacteria < 3 µm) (Cyanobium sp. ITAC108 and Synechococcus sp. ITAC107) isolated from the Mediterranean sponge Petrosia ficiformis were analyzed. The biological effects of organic and aqueous extracts from these picocyanobacteria toward the nauplii of Artemia salina, sea urchin embryos and human cancer lines (HeLa cells) were evaluated. Methanolic and aqueous extracts from the two strains strongly inhibited larval development; on the contrary, in ethyl acetate and hexane extracts, the percentage of anomalous embryos was low. Moreover, all the extracts of the two strains inhibited HeLa cell proliferation, but methanol extracts exerted the highest activity. Gas chromatography–mass spectrometry analysis evidenced for the first time the presence of β-N-methylamino-l-alanine and microcystin in these picocyanobacteria. The strong cytotoxic activity observed for aqueous and methanolic extracts of these two cyanobacteria laid the foundation for the production of bioactive compounds of pharmacological interest.

Cryptosporidium spp. are common protozoan pathogens in mammals. The diversity and biology of Cryptosporidium in tree squirrels are not well studied. A total of 258 Eurasian red squirrels (Sciurus vulgaris) from 25 and 15 locations in the Czech Republic and Slovakia, respectively, were examined for Cryptosporidium spp. oocysts and specific DNA at the SSU, actin, HSP70, TRAP-C1, COWP, and gp60 loci. Out of 26 positive animals, only juveniles (9/12) were microscopically positive (18,000 to 72,000 OPG), and molecular analyses revealed the presence of Cryptosporidium sp. ferret genotype in all specimens. Oocysts obtained from naturally-infected squirrels measured 5.54–5.22 μm and were not infectious for laboratory mice (BALB/c and SCID), Mongolian gerbils, Guinea pigs, Southern multimammate mice, chickens, or budgerigars. None of naturally infected squirrels showed clinical signs of disease. The frequency of occurrence of the ferret genotype in squirrels did not vary statistically based on host age, gender or country of capture. Phylogenetic analysis of sequences from six loci revealed that Cryptosporidium sp. ferret genotype is genetically distinct from the currently accepted Cryptosporidium species. Morphological and biological data from this and previous studies support the establishment of Cryptosporidium sp. ferret genotype as a new species, Cryptosporidium sciurinum n. sp.
Fabrication of Josephson junctions by single line etching of Nb thin films utilizing nitrogen-gas-field ion-source focused ion beam
Authors: Sudo Shinya , Akabori Masashi , Uno Munenori 
Published: September 2021

Abstract
We focused on a focused ion beam (FIB) technology, called nitrogen gas field ion source FIB (N2 GFIS-FIB), which can etch directly at the 10 nm level or finer. We performed single line etching of Nb thin film microbridges deposited by N2 GFIS-FIB and fabricated Josephson junction (JJ) devices. The microbridge area was separated into two parts by the processing line, whose width was around 20 nm. We performed electrical characterizations of the devices at low temperature and observed typical behaviors of JJ devices, such as a superconducting current region and current jumping to the normal current region in some of the deeply etched devices. We also observed an AC resistance oscillation in some of the shallowly etched devices. The oscillation may be due to a sub-harmonic gap structure that originates from Andreev reflection. These results indicate that simple single line etching of Nb by N2 GFIS-FIB can form JJ devices.

Abstract
We present a study on morphological control of nanostructured Ge films by the Ar gas pressure in plasma sputtering deposition. In the low Ar-gas-pressure range, aggregated islands of amorphous grains are formed on the film surface, while in the high-pressure range of 500 mTorr monodisperse nano-grains of about 30 nm in size are orderly arranged without aggregation. The film porosity shows a high value of over 10%. We tested the charge/discharge cycle performance of Li-ion batteries with nanostructured Ge films as anodes. The battery cell with an ordered arrangement structure maintained a high capacity of 434 mAh g−1 after 40 charge/discharge cycles, while that with an aggregated structure exhibited a rapid degradation of capacity to 5.08–183 mAh g−1. An ordered arrangement of Ge nano-grains with a high porosity, which is realized in a simple one-step procedure using high Ar-gas-pressure plasma sputtering, is effective for the stable cycling of high-capacity metal anodes.

Introducción: la diabetes mellitus tipo 2 (DM2) es el tipo más común de diabetes la cual ocurre generalmente en adultos, sin embargo, hay reportes que la describen en adolescentes y adultos jóvenes.
Objetivo: describir las características clínicas y el tratamiento de la diabetes tipo 2 en adultos jóvenes en un hospital colombiano.
Material y métodos: estudio de corte transversal entre el 2017 y 2019, que incluyó pacientes adultos jóvenes entre 18 y 40 años con DM2, que fueron atendidos en el Hospital Santa Mónica de Dosquebradas, Colombia. La unidad de análisis fueron las historias clínicas. Se incluyeron variables sociodemográficas, clínicas, farmacológicas y control metabólico (HbA1c < 7.0%). Se realizaron análisis descriptivos y se aplicó una regresión logística binaria (p< 0.05).
Resultados: se identificaron 124 pacientes de los cuales 83 (70.0%) cumplieron criterios de inclusión, con una edad media de 33.7 ± 5.3 años. Unos 28 pacientes eran obesos (33.7%). Además, 21 pacientes (25.3%) presentaron control metabólico. Los fármacos más usados fueron metformina en 64 pacientes (77.1%), seguido de las insulinas en 46 pacientes (55.4%). Se estableció que 51 de estos (61.4%) presentaron adherencia al tratamiento. No hubo pacientes con terapia triple como estrategia terapéutica. Los pacientes con retinopatía diabética presentaban una probable asociación con tener control de la enfermedad en el momento del estudio (P=0.048, OR:0.130; IC95%:0.017-0.987).
Conclusiones: los pacientes adultos jóvenes presentan pobre control metabólico y uso frecuente de insulinas.
Kamusal Alanı Dijitalleşme Çerçevesinde Yeniden Okumak
Authors: AVCİL Ceren 
Published: September 2021

Kamusal alan, 18. yüzyıldan itibaren sanayileşme süreci ile görünür ve tartışılır hale gelen bir kavram olmuştur. Kamusal alan kavramına yönelik yapılan tanımlamalar kamusal alan-özel alan ikiliği veya karşıtlığı çerçevesinde ele alınmakla birlikte her ikisi arasında keskin bir ayrım olmaması gerektiğine dair görüşler de mevcuttur. Modernleşmenin getirmiş olduğu toplumsal, ekonomik, siyasal ve kültürel alt üst oluşlar kamusal ve özel mekânların niteliğini ve içeriğini de dönüştürmüştür. Ayrıca, kavram tanımlamasında hem kavramın herhangi bir mekâna işaret etmemesi hem de içeriğinin net olmaması kavrama yönelik net tanımlamaların yapılmasını da zorlaştırmaktadır. Bu çalışmada öncelikle kamusal alanın dönüşümüne yönelik tartışmalara yer verilecektir.Başta Habermas ve Sennett olmak üzere özel alan-kamusal alan tanımlamaları ve kavramların nitelikleri üzerinde durulacaktır. Sonrasında dijitalleşme süreci ile birlikte yeni medyanın ve kitle iletişim araçlarının dijital kamusal alanın oluşumuna imkân verebilirliği tartışılacaktır. Dijitalleşme süreci ile birlikte farklı kamusallıkların oluşma ihtimali, geleneksel kamusal-özel alan tartışmalarını farklı bir boyuta taşır niteliktedir. Dijitalleşen kamusal alan, zamana, mekâna ve bireye yönelik algıların dönüşüm sürecini gündeme getirmiştir.

Published: September 2021

Объём потребления энергии, в том числе и электрической, в нашей стране непрерывно увеличивается. В связи с этим возникает необходимость максимального снижения затрат электрической энергии. В статье рассматривается возможность снижения электрической энергии в приточных системах вентиляции за счёт использования вентиляторов-доводчиков. Приведены результаты аэродинамического расчета двух вариантов приточной системы вентиляции промышленного здания. Первый вариант - традиционная схема с одним общим центральным вентилятором. Второй вариант - схема с использованием вентиляторов-доводчиков на отдельных ветвях системы. В результате проведенных расчетов показано, что установка вентиляторов-доводчиков позволит существенно снизить нагрузку на привод центрального вентилятора.
The volume of energy consumption, including electricity, in our country is constantly increasing. In this regard, it becomes necessary to reduce the cost of electrical energy as much as possible. The article discusses the possibility of reducing electrical energy in supply ventilation systems through the use of fans. We present the results of the aerodynamic calculation of two variants of the supply ventilation system of an industrial building. The first option is the traditional scheme with one common central fan. The second option is a scheme using fan coil units on separate branches of the system. As a result of the calculations, it is shown that the installation of fan coil units will significantly reduce the load on the central fan drive.

FILOSOFIAS DE ARKHÉ COMO ENFRENTAMENTO AO ONTOCÍDIO: ORALIDADE E CULTURA AFRO-BRASILEIRA / Arkhé Philosophies against the Ontocide: Orality and Afro-Brazilian culture
Authors: Andre de Souza Mateus Raynner 
Published: September 2021

Neste ensaio parto de uma compreensão da modernidade como um momento na história do pensamento que, entre outras coisas, em sua prática de dominação e subjugação dos corpos africanos e afrodiaspóricos – e por que não citar os corpos ameríndios? –, acabou por sobrevalorizar somente o conhecimento escrito e letrado, descartando a oralidade e a identificando como algo menor. Defendo a hipótese de que, ao negar a esses corpos a Palavra, negou-lhes também o Ser, movimento que denomino ontocídio. Defendo também a compreensão das festas afro-brasileiras como filosofias – compreendidas como filosofias de arkhé – e as demonstro como locais de enfretamento das práticas coloniais e de reontologização. Considero que esta discussão, desenvolvida mediante uma revisão bibliográfica, possa promover novas reflexões para um conhecimento menos colonizado.Palavras-chave: Manifestações culturais; Modernidade; Filosofias africanas e da diáspora; Ontocídio. AbstractThis essay presupposes a meaning of modernity as a moment in the history and as practice of domination and subjugation of African and Afro-diasporic bodies – and why not mention Amerindian bodies –, ended up overvaluing knowledge as something written and literate, discarding oral knowledge and identifying it as something less. The hypothesis to be defended is that by denying these beings the Word, they also denied the Being, a movement that I am calling here ontocide. It is also a hypothesis that Afro-Brazilian manifestations are understood as philosophies, called here arkhé philosophies, I intend to show them precisely as a form to confront colonial practices and as a site for reontologization. I believe that the discussion marked through a bibliographic review can promote new reflections for a less colonized knowledge.Keywords: Cultural manifestations; Modernity; African and Diaspora philosophies; Ontocide.
