Abstract. Simarmata M, Apriantonedi R, Setyowati N, Pujiwati H. 2023. Possibility of glyphosate-resistant goosegrass (Eleusine indica) in citrus fields in Rejang Lebong Districts, Bengkulu, Indonesia. Biodiversitas 24: 3633-3638.Weed abundances dominated by goosegrass (Eleusine indica L.) are a major constraint in the citrus fields of Rejang Lebong District, Province of Bengkulu, Indonesia. The objectives of this research were to investigate weed control methods applied by citrus farmers, analyze the dominant weed, and study the possibility of glyphosate resistance in goosegrass. A survey was conducted by interviewing three citrus farmers regarding weed control measures, followed by weed assessment in 10 sampling plots of each location. Then, field trials were conducted to evaluate glyphosate efficacy on weeds in the three locations of citrus fields. The survey found that glyphosate has been applied for weed control up to 4 L ha-1( 1.92 kg a.i. ha-1 of isopropyl amine salt) 2 to 3 times a year, and the farmers found that some weeds were resistant to glyphosate. Weed assessment showed that goosegrass is a dominant species with a summed dominance ratio (SDR) of 67.1, 70.8, and 79.0% at each location, respectively. The field trials observed that the levels of survival weeds in the experimental plots treated with glyphosate at 0.5, 1.0, 2.0, 4.0, and 8.0 L ha-1were 94-95%, 83-85.3%, 70-73.3%, 20-29%, and 10-12.3%, respectively. Goosegrass was identified as the survivor's weeds. The glyphosate doses (LD50) required to eradicate 50% of the weed populations ranged between 2 and 4 L ha-1 at the three sites. This study proved that goosegrass in the citrus groves of Rejang Lebong District, Bengkulu, is resistant to glyphosate.

Published: July 2023

Este estudo teve por objetivo descrever as propriedades químico-biológicas dos marcadores químicos presentes na espécie vegetal Pterodon emarginatus, conhecida popularmente como “Sucupira”, por meio de técnicas in silico. Essa árvore é encontrada principalmente em regiões do Cerrado e em áreas de transição entre as florestas semidecíduas de São Paulo e de Minas Gerais. Trata-se de uma pesquisa observacional e experimental. Os marcadores químicos da espécie em estudo foram obtidos a partir de um levantamento bibliográfico com o propósito final de identificar aqueles com a melhor chance de se tornar um medicamento eficaz para os pacientes. Em geral, as moléculas devem apresentar alta atividade biológica aliada a baixa toxicidade. Para estimar isso, uma série de programas de computador foram empregados para avaliar a estrutura, a farmacocinética - absorção, distribuição, metabolismo e excreção -, a “drugLikeness” e a compatibilidade química desses compostos. Esses modelos computacionais são capazes de reduz drasticamente a fração de falha relacionada à farmacocinética nas fases clínicas. Também foi estimado virtualmente em quais receptores as substâncias atuariam, com modelos de interação molecular e o quão estáveis seriam esses complexos formados. Apenas 3 componentes foram selecionados: vouacapano-6 α, 7 β, 14 β, 19-tetraol, geranilgeraniol e α-humuleno. Todos apresentaram alta probabilidade de atuarem com propriedades antineoplásicas e anti-inflamatórias, sendo o α-humuleno o mais promissor, ligando-se aos receptores ativados por proliferadores peroxissomais do tipo alfa e apresentando boa interação entre as moléculas. Dessa forma, abrem-se portas para estudos pré-clínicos, in vitro e posteriormente in vivo dessa substância, para medir a eficácia e a toxicidade de um possível fármaco antes de administrar um medicamento aos humanos.
La Star de soccer, figure de « la diversité » au Canada
Authors: Sirois-Moumni Bachir , St-Louis Jean-Charles 
Published: July 2023

Dans cet article, nous soutenons que les Stars du soccer au Canada et au Québec, telles que Alphonso Davies et Patrice Bernier, sont des exemples de la « production de la diversité » dans le paysage culturel sportif et médiatique canadien. Davies et Bernier y représentent des formes culturelles qui intègre dans une intrication complexe le sport spectacle, sa marchandisation et la création de mythes collectifs. Dans un système sportif longtemps dominé par le hockey, ils représentent tous deux des points nodaux dans les luttes incessantes autour de la (re)définition de la citoyenneté et de l’appartenance. En explorant notamment leur mise en récit paradoxale comme « immigrants idéaux » au prisme de leur racisation, cet article contribue à éclairer les dynamiques culturelles propres de l’environnement du sport et des médias dans les contextes canadien et québécois. Notre analyse vise ainsi à montrer comment les récits mobilisés pour raconter les trajectoires de Davies et Bernier au sein du complexe culturel média/sport canadien participent de la gouvernementalité propre aux régimes inspirés du multiculturalisme et de l’interculturalisme, reproduisant les inégalités et la discrimination à même un discours qui se veut ouvert et bienveillant.

El desarrollo de la presente producción permite describir la incidencia del bilingüismo y el origen del estudiante en el desempeño escolar en el Paraguay. El método utilizado es el analítico y sintético. Los resultados obtenidos, contribuyen a comprobar la falta de inversión y las escasas políticas públicas de parte del Estado para la educación rural, así como la definición de acciones para mejorar y hacer llegar los mejores resultados a los sectores más desfavorecidos. Se concluye que en la actualidad la innovación social puede generar un valor colectivo social en lugar de un valor individual, una educación basada en el conocimiento y la innovación, a partir de acciones concretas, con la incorporación de talleres de artes oficios, escuelas que respondan a la demanda regional con orientación agropecuaria y ambiental y principalmente que las autoridades puedan democratizar el sector, capacitar a los docentes, mejorar el acceso e incentivar la innovación social, vincular la innovación con las demandas sociales de cada región, con la participación ciudadana y el relacionamiento entre los entes como las empresas, el estado y la universidad.
Host sex disparity and viral genotype dependence of the glycosylation level of small Hepatitis B surface protein in patients with HBeAg-positive chronic Hepatitis B
Authors: Ou Guomin , Zhao Chengyu , Deng Juan , Zhuang Hui , Xiang Kuanhui , Li Tong 
Published: July 2023

Abstract
Background
Hepatitis B surface antigen (HBsAg) consists of six components of large/middle/small HBs proteins (L/M/SHBs) with non-glycosylated (ng)- or glycosylated (g)- isomers at sN146 in their shared S domain. g-SHBs plays a crucial role in hepatitis B virus (HBV) secretion. However, the host and viral factors impacting sN146 status in natural HBV infection remain revealed mainly due to the technical difficulty in quantifying g-SHBs and ng-SHBs in serum samples.

Methods
To establish a standardized Western blot (WB) assay (WB-HBs) for quantifying the SHBs isomers in serum samples of 328 untreated hepatitis B e antigen (HBeAg)-positive chronic hepatitis B (CHB) patients with genotype B or C HBV infection. The 1.3-mer HBV genotype B or C plasmids were transiently transfected into HepG2 cells for in vitro study.

Results
The median level of ng-SHBs was significantly higher than that of g-SHBs (N = 328) (2.6 vs. 2.0 log10, P < 0.0001). The median g-/ng-SHBs ratio in female patients (N = 75) was significantly higher than that of male patients (N = 253) (0.35 vs. 0.31, P < 0.01) and the median g-/ng-SHBs ratio in genotype C patients (N = 203) was significantly higher than that of the genotype B patients (N = 125) (0.33 vs. 0.29, P < 0.0001).

Conclusions
Our findings suggest that the g-/ng-SHBs ratio is host-sex-biased and viral genotype dependent in treatment naïve patients with HBeAg-positive chronic hepatitis B, which indicates the glycosylation of SHBs could be regulated by both host and viral factors. The change of ratio may reflect the fitness of HBV in patients, which deserves further investigation in a variety of cohorts such as patients with interferon or nucleos(t)ide analogues treatment.
Chronic neck pain is associated with increased mortality in individuals with osteoarthritis: results from the NHANES database prospective cohort study
Authors: Chen Xi , Gong Lihua , Li Cheng , Wang Siyuan , Zhou Yixin 
Published: July 2023

Abstract
Background
Neck pain (NP) is a common symptom reported in the elderly. However, no study has examined the relationship between NP and osteoarthritis (OA) so far, and this study aimed to investigate the association of neck pain with the prevalence and mortality of OA.

Methods
A total of 5965 participants were included in this cohort study based on the National Health and Nutrition Examination Survey data set of the USA (NHANES). Death outcomes follow-up information was ascertained by linkage to National Death Index (NDI). The association between NP and OA was studied by multi-various logistic regression models after adjusting for potential confounding factors. Cox proportional hazards models were used to elucidate the relationship between NP and all-cause mortality in OA patients.

Results
Among all participants, 8.18% had osteoarthritis, and 5.92% suffered from neck pain. Neck pain was associated with osteoarthritis [1.932 (1.232, 3.028), p < 0.01], which still reminded significant after adjustments [2.519 (1.325, 4.788), p < 0.01] and stratified analysis by sex, race, and smoke status. In OA patients, chronic neck pain (over 1 year) was significantly associated with higher risks of all-cause mortality before [2.94 (1.61, 5.37), p < 0.01] and after adjustment [3.30 (1.23, 45.85), p < 0.05].

Conclusion
Neck pain was strongly associated with osteoarthritis. Moreover, chronic neck pain over 1 year significantly increased the mortality of OA patients. Our study demonstrates the need to screen osteoarthritis in the neck pain population and select a more appropriate treatment strategy promptly for those patients.
Risk of cancer survivors with second primary thyroid cancer: an analysis of data from the SEER database
Authors: Yuan Yewei , Sun Peng , Xiao Hualin , Li Lingfan , Li Junyan , Ai Xiang 
Published: July 2023

Abstract
Background
A risk factor for thyroid cancer (TC) may be a history of former cancer and cancer therapy. The precise risk of a second primary thyroid carcinoma has not yet been revealed. In this study, we evaluated Standardized Incidence Ratios (SIRs) of second primary thyroid cancer (SPTC) with consideration of different conditions and further analyzed the clinicopathological characteristics and survival of these patients.
Methods
The cohort was selected from the SEER Program between 2000 and 2018. The standardized incidence ratios, morbidity risk, clinicopathological features, and survival of second primary thyroid carcinoma were analyzed. Propensity score matching (PSM) was used to balance covariates. Kaplan–Meier method and Cox regression were performed to assess the survival outcomes.
Results
Overall, 7,066 patients with SPTC and 83,113 patients with primary TC were identified. The SIR of TC in tumor patients was 1.51/10000, statistically higher than the natural population (0.94/10000, P < 0.05). The most significant tumors contributing to the increased SIRs of SPTC were acute lymphocytic leukemia (3.49/10000), Hodgkin’s lymphoma-nodal (3.29/10000), salivary gland cancer (3.23/10000), and kidney and renal pelvis cancer (3.05/10000). The incidence of TC increased significantly in tumor patients who received radiotherapy/ chemotherapy before age 35. The age at diagnosis of the SPTC was much older than the primary TC (64.01 vs. 49.55 years, p < 0.001). The SPTC had a higher percentage of histological grades 3/4 (23.14% vs. 15.19%, p < 0.001). Survival analyses demonstrated a worse prognosis for the SPTC group compared to the primary TC group. But after PSM, the survival outcomes of the two groups tended to be equivalent (P = 0.584).
Conclusions
The SIRs of TC are higher in tumor patients. The most significant factors contributing to the increased risk of SPTC were some specific former tumors and acceptance of radiotherapy/ chemotherapy before age 35. There was no significant difference in survival between SPTC and primary TC.

Published: July 2023

IntroductionThis study explored the effects of Qigong exercises on upper extremity muscle activity, balance function, and quality of life in stroke patients.MethodsA total of 30 stroke patients were randomly allocated to either control group or Qigong group. In the Qigong group, participants completed an intervention of Qigong Baduanjin over 8 weeks. Data on the electromyographic activities of the biceps brachii muscle, triceps brachii muscle, and muscle coordination were obtained using surface electromyography and the co-contraction ratio (CCR). Data on balance were obtained using the PK254P balance function detection system. Quality of life was measured using the brief version of the World Health Organization Quality of Life scale.ResultsThe results for the Qigong group showed a significant difference in CCR of the triceps brachii muscle (p &lt; 0.01). Concerning balance (assessed using the open-eye test), there was a significant decrease (p &lt; 0.05) in Y-axis trajectory deviations and the Y-axis speed in the Qigong group. In the closed-eye test, the peripheral area of the Qigong group was significantly lower than that of the control group (p &lt; 0.05). Significant differences were also observed in physical health (p &lt; 0.05), psychological health (p &lt; 0.01), environment (p &lt; 0.01), and the total scores for quality of life (p &lt; 0.01) in the Qigong group.DiscussionWe conclude that Qigong exercises improve the quality of life in stroke patients and have positive effects on the coordination of limb extremities and balance function.

Published: July 2023

ABSTRACT

Introduction:
Assessment of antibody response to vaccination against SARS CoV2 has clinical, public health, and policy implications during the pandemic and in the context of future waves.

Method:
In this repeated cross-sectional study, we estimated total binding antibody levels to the spike protein of the SARS CoV2 virus post two doses of Covishield vaccine among 133 health care workers (HCWs) (phase 1), followed by antibody levels among a subset (n = 61) of this group at 9 months after the second dose (phase 2). The time period of the first and second blood collection corresponds to Delta and Omicron waves, respectively.

Results:
We report 100% seroconversion post 28 days of the second dose of the Covishield vaccine among infection naïve HCWs. In this study, 33% had a breakthrough infection in phase 1 and 24% reported a history of infection in phase 2. The antibody titres were higher in the breakthrough infection group compared to the infection naïve group during both Delta and Omicron waves.

Conclusion:
This shows that there is a good seroconversion with two doses of vaccine, weaning of antibody with time, and a rise of antibody titre if infected with SARS CoV 2 subsequently.

Authors: Rani Salma , Khan Aqil , Ali Naveed , Khan Khalid 
Published: July 2023

This study estimates the prevalence rate of multidimensional poverty, and determines its socio-economic determinants through survey of Behram Dheri, a Union Council of district Charsadda. The prevalence and severity of multidimensional poverty has been estimated through Alkire-Foster approach having ten indicators of multidimensional poverty. Whereas, binary-logit model has been employed to determine the impact of contributory determinants of poverty on multidimensional poverty. In result it is concluded that the incidence of poverty is 0.842 which interprets that about 84% of the households are multidimensionally-poor in the study area. However, the intensity of poverty is 0.559 which implies that at average a household is deprived in almost 56% of the indicators in UC Behram Dheri. Finally it has been concluded that the prevalence rate of the multi-dimensional poverty index is 0.4712. The logistic regression model results show that the non-ownership of agricultural land and livestock and households headed by female are more vulnerable to multidimensional poverty. Moreover the results also concluded that people who are dwelling in nuclear family are less vulnerable to multidimensional poverty. It is also calculated that the families which have more dependent members have direct relation with multidimensional poverty. On the basis of results, it is recommended to implement anti-poverty programs, combined with quality education, training, and awareness at the grass-roots level, will undoubtedly ensure rural households' socio-economic empowerment.
