Uma introdução ao teatro esquivo da esquiva Sabina Berman
Authors: Bixler Jacqueline
Published: April 2023

Bixler analisa o teatro de Sabina Berman e as razões de seu sucesso no México e em demais países. Sabina é uma autora difícil de ser analisada por ser prolífica, original e atrevida e suas obras estarem sempre em mutação. É também difícil de ser resumida, já que apresenta uma grande variedade estilística e temática. Mesmo pertencendo à geração dos Novos Dramaturgos, Sabina segue seu próprio caminho. Diversos críticos dos Estados Unidos discorrem sobre seu teatro e conhecem bem a autora e sua obra, mas a veem de uma perspectiva distanciada e meio “gringa”, segundo a opinião da própria Sabina.

O corpo-vivido do ator. Caminhos para a formação do ator na contemporaneidade
Authors: Ziroldo Pedro José de Freitas
Published: April 2023

O Teatro Pós-Moderno trouxe mudanças paradoxais e também discussões referentes à composição da cena e sua dramaturgia, principalmente à função do ator e de sua atitude cênica. A atenção ao corpo, a presença e o gesto de “autorrepresentação” parecem caracterizar o trabalho do ator no teatro contemporâneo. O corpo em questão, trata-se do próprio sujeito. O ator torna-se um “ser-em-cena”, e seu ato é entendido como fenômeno e experiência na cena. O conceito “corpo-vivido”, de Merleau-Ponty, pode contribuir para a formação deste “novo ator”, diante das transformações que acompanham o teatrocontemporâneo.

Original bulk phases of two-dimensional atomic crystal materials are layered. However, a few relevant researches show that some of two-dimensional material crystals have non-layered bulk phases. In this work we investigate monolayer CuSe which is non-layered, belonging in a new kind of honeycomb graphene analogue. Monolayer CuSe is not suitable for application in electronic devices because of its metallic nature. In order to find new two-dimensional atomic crystal materials with excellent performance suitable for application in electronic devices, we change CuSe from metal to semiconductor through external atom modification. The first principles study of density functional theory is conducted to ascertain the energy band structure of monolayer CuSe after second periodic atoms have been added to the top, center and bridge sites. The characteristics of monolayer CuSe with addition of Li or B atoms are studied, including energy band structure, the density of states, differential charge density, and crystal orbital Hamiltonian population. The results show that after adding Li atoms to CuSe, the CuSe transforms from metallic to semiconductive property at all three positions, and Li atom is more easily to be modified in the hexagonal center of CuSe, with band gap being about 1.77 eV, the Fermi level biased towards the top of the valence band. The CuSe with addition of Li atoms exhibits a p-type semiconductor property, so it is a direct bandgap semiconductor. Adding B atom to the top of Cu atom can also make CuSe semiconductive, with a band gap of about 1.2 eV, the conduction band minimum at the K point, and the valence band maximum at the Γ point. The CuSe with addition of B atoms belongs in an indirect band gap semiconductor, and the Fermi energy level is biased towards the conduction band minimum, exhibiting the characteristics of an n-type semiconductor. According to the results of differential charge density and crystal orbital Hamiltonian population, the B atom is bound to the top of the monolayer CuSe with the B-Se polar covalent bond. The first principle study reveals the realization of metal-to-semiconductor transition from monolayer CuSe to CuXSe (X = Li, B), and the calculation results also show that CuSe with addition of Li atoms or B atoms is likely to be used in future electronic devices.

The bloodstream represents a hostile environment that bacteria must overcome to cause bacteraemia. To understand how the major human pathogen Staphylococcus aureus manages this we have utilised a functional genomics approach to identify a number of new loci that affect the ability of the bacteria to survive exposure to serum, the critical first step in the development of bacteraemia. The expression of one of these genes, tcaA, was found to be induced upon exposure to serum, and we show that it is involved in the elaboration of a critical virulence factor, the wall teichoic acids (WTA), within the cell envelope. The activity of the TcaA protein alters the sensitivity of the bacteria to cell wall attacking agents, including antimicrobial peptides, human defence fatty acids, and several antibiotics. This protein also affects the autolytic activity and lysostaphin sensitivity of the bacteria, suggesting that in addition to changing WTA abundance in the cell envelope, it also plays a role in peptidoglycan crosslinking. With TcaA rendering the bacteria more susceptible to serum killing, while simultaneously increasing the abundance of WTA in the cell envelope, it was unclear what effect this protein may have during infection. To explore this, we examined human data and performed murine experimental infections. Collectively, our data suggests that whilst mutations in tcaA are selected for during bacteraemia, this protein positively contributes to the virulence of S. aureus through its involvement in altering the cell wall architecture of the bacteria, a process that appears to play a key role in the development of bacteraemia.

Striatal ensemble activity in an innate naturalistic behavior

Published: April 2023

Self-grooming is an innate, naturalistic behavior found in a wide variety of organisms. The control of rodent grooming has been shown to be mediated by the dorsolateral striatum through lesion studies and in-vivo extracellular recordings. Yet, it is unclear how populations of neurons in the striatum encode grooming. We recorded single-unit extracellular activity from populations of neurons in freely moving mice and developed a semi-automated approach to detect self-grooming events from 117 hours of simultaneous multi-camera video recordings of mouse behavior. We first characterized the grooming transition-aligned response profiles of striatal projection neuron and fast spiking interneuron single units. We identified striatal ensembles whose units were more strongly correlated during grooming than during the entire session. These ensembles display varied grooming responses, including transient changes around grooming transitions or sustained changes in activity throughout the duration of grooming. Neural trajectories computed from the identified ensembles retain the grooming related dynamics present in trajectories computed from all units in the session. These results elaborate striatal function in rodent self-grooming and demonstrate that striatal grooming-related activity is organized within functional ensembles, improving our understanding of how the striatum guides action selection in a naturalistic behavior.
Phylogenetic relationship and comparative analysis of the main Bupleuri Radix species in China
Authors: Wang Ping , Bai Jiqing , Li Xue , Liu Tiantian , Yan Yumeng , Yang Yichang , Li Huaizhu
Published: April 2023

Background

Bupleuri Radix (Chaihu) is a famous traditional Chinese medicine derived from Bupleurum, Apiaceae. The origin of cultivated Chaihu germplasm in China is unclear, which has led to unstable Chaihu quality. In this study, we reconstructed the phylogeny of the main Chaihu germplasm species in China and identified potential molecular markers to authenticate its origin.

Methods

Three Bupleurum species (eight individuals), B. bicaule, B. chinense, and B. scorzonerifolium, were selected for genome skimming. Published genomes from B. falcatum and B. marginatum var. stenophyllum were used for comparative analysis.

Results

Sequences of the complete plastid genomes were conserved with 113 identical genes ranging from 155,540 to 155,866 bp in length. Phylogenetic reconstruction based on complete plastid genomes resolved intrageneric relationships of the five Bupleurum species with high support. Conflicts between the plastid and nuclear phylogenies were observed, which were mainly ascribed to introgressive hybridization. Comparative analysis showed that noncoding regions of the plastomes had most of the variable sequences. Eight regions (atpF-atpH, petN-psbM, rps16-psbK, petA-psbJ, ndhC-trnV/UAC and ycf1) had high divergence values in Bupleurum species and could be promising DNA barcodes for Chaihu authentication. A total of seven polymorphic cpSSRs and 438 polymorphic nSSRs were detected across the five Chaihu germplasms. Three photosynthesis-related genes were under positive selection, of which accD reflected the adaptation fingerprint of B. chinense to different ecological habitats. Our study provides valuable genetic information for phylogenetic investigation, germplasm authentication, and molecular breeding of Chaihu species.

DESCARTES: SEMEJANZA Y REPRESENTACIÓN. UNA ANALOGÍA PICTÓRICA
Authors:   Universidad del Valle (Colombia), Margot Jean-Paul
Published: April 2023

En algunos textos cartesianos asistimos a una especie de doble juego de semejanza y representación. La cosa, causa de lo que sentimos, no es lo que sentimos. Es necesario expulsar los lenguajes miméticos, advertir que conocer la naturaleza es descifrar signos, signos que la naturaleza produce en la geometría, para poder asegurar su representación objetiva. El modelo mecanicista es introducido por una analogía pictórica, que funciona como un corte entre la semejanza y la representación, para conseguir que la representación sea semejante.
Theology of Land: Reflections and Dialogue from a South African Socio-Political Perspective
Authors: Resane Kelebogile Thomas
Published: April 2023

This paper examines the current situation of land possession in the South African socio-political space. Land possession in South Africa is an emotive issue that receives different political responses based on historical constitutional land laws and declarations, such as the Freedom Charter of 1954. African views on land are elaborated, together with South African current political debates regarding land. Negative politics of the land leave the dispossessed humiliated, experiencing feelings of indignity and insentience. Being robbed of the land is humiliating, but the dialogue about regaining it should occur in the spirit of eschatological hope with one goal in mind: inheriting the land. The paper further elaborates a theology of the land and extensively explains its historical and biblical evolvement from the Abrahamic era to the period of exile. In the midst of tensions between colonial views of land and cultural clashes, eschatological hope is the route to take. Citizens are to be granted the rights and promises that lead to eschatological peace, which creates coexistence where life is fully experienced. Eschatological hope should not be read as opium with a calming effect or a soothing balm for people to endure injustice. It should be a message of hope for the restoration of quality of untrammelled joy on the fruitfulness of the land. All this is achievable through dialogue by and with all stakeholders regarding land issues. The contribution made by this article is the acknowledgement of the imbalances regarding the land issue, and it attempts to bring forth a theological understanding of land and how to apply it in the current South Africa.

Monkeypox: An Uncommon Re-emerging Virus- Threat to Mankind
Authors: Mankar Ashwini Arun , Sande Suvarna Vaibhav , Chaubey Priyanka Purushottam
Published: April 2023

Monkeypox Virus (MPV) causes rare zoonotic illness. The Central African (or Congo Basin) clade and the West African clade are its two genetic subgroups, of which Central African subgroup is more lethal. To distinguish between the lineages, sequencing is crucial. As it was first isolated from captive monkeys that is why it is named as MPV. Its clinical features are similar to small pox. Undiagnosed acute rash with one or more symptoms, such as headache, fever, lymphadenopathy, myalgia, back pain, or asthenia, are considered common clinical findings. Real-Time Polymerase Chain Reaction (RT-PCR) is used in the laboratory diagnosis. There are various complications of monkeypox disease that includes bacterial infection of skin, skin scarring, hyper or hypopigmentation, permanent corneal scarring (vision loss), pneumonia, dehydration, sepsis, encephalitis and death. The drug of choice includes Tecovirimat, Cidofovir, Vaccinia Immune Globulin Intravenous (VIGIV), Brincidofovir. ACAM2000, LC16m8 and modified vaccinia Ankara are few options for vaccines but still under investigation. Though the disease is self-limiting but may complicate and has morbidity as well as mortality. So, it’s better to prevent the spread of the disease by early identification, contact tracing, isolation with stringent hospital infection control practices with early initiation of treatment.

The study is based on the primary and secondary data. The total sample size comprised of 60 farmers also selected 20 market intermediaries for the study. In Chikkaballapura three major marketing channels were identified namely Channel I: Producer→ Commission agent→ Wholesaler→ Retailer→ Consumer Channel II: Producer→ Pre-harvest Contractor→ Commission agent cum Wholesaler→ Retailer→ Consumer. Channel III: Producer→ Village trader→ Retailer→ Consumer. About 65.00 % of the producer used Channel-I followed by channel-II (28.33%) and remaining through channel-III (6.67%). Price spread in channel-II is high (Rs. 8,985) as compared to Channel-I (Rs. 5,922) and producers share in consumer rupee is high in channel-I (58.51 per cent) which is considered to be better marketing channel as compared to channel-II (47.72 per cent). Proper market structure needs to be created to the floriculture crops in the study area and Chrysanthemum flower need to put under the list of notified commodities and commission charges taken from producer can be strictly prohibited.

The sale of soft drinks in and around primary schools is recurrent in Côte d'Ivoire. The objective of this work is to evaluate the rate of some biochemical and physicochemical parameters and the health risks related to the consumption of soft drinks. The biochemical and physicochemical parameters were determined according to the standard SOXHLET technique, that of Kjeldhal and also that described by Dubois et al in1956. Potentially pathogenic and pathogenic germs were enumerated and researched according to reference methods described by AFNOR. The moisture content of the different beverages ranged from 3.9±0.05 to 3.2±0.05, and the sugar content from 26.06±2.05 to 5.96±1.60. For the acidity, the higher value was 0.93± 0.15 (Bissap juice) and the lowest was 0.64± 0.02 (Tamarind juice). For proteins, the high value was 44.15 ± 0.11 (Milk Mint Juice) and the low value was 38.15 ± 0.11 (Ginger Juice). As for dry matter, the highest value was found in ginger juice (44.76 ±0.02) and the lowest in bissap juice (40.96 ±0.01). Soft drinks sold in Williamsville schools contain such potentially pathogenic species as Staphylococcus aureus and Bacillus cereus with a wide range of loadings in the drinks. Escherichia coli was not identified. No Salmonella was observed in the different soft drinks analyzed. The presence of potentially pathogenic germs could pose a danger to school children.

All total 21 F1 crosses of local landraces were evaluated along with seven parents and one check of brinjal by adopting RBD replicated twice at AICRP on Vegetable Crops, OUAT, Bhubaneswar, Odisha. The objective of the experiment was to evaluate the performance of F1 crosses for growth, flowering, fruit yield and yield attributes. Results revealed significant variations among various vegetative characters (plant height : 74.50 cm to 110.90 cm, plant spread (EW): 72.75 cm to 89.55 cm and NS :70.00 cm to 91.25cm, primary branches plant-1: 4.00 to 5.40), flowering parameters (days to 1st flowering:45.60 to 55.00 and 50% flowering: 55.00 to 66.40) and fruit yield attributes (fruit length:11.35 cm to 16.35 cm, fruit breadth :15.35 cm to 25.75 cm, fruit weight:118.40 g to 217.30g and fruits plant-1: 11.80 to 17.70). The F1 cross viz. BBSR-08-2 × Selection from BBSR-145-1(2.09 kg) recorded significantly highest fruit yield plant-1 followed by BBSR-08-2 × BBSR-10-25(1.98 kg) and BBSR-08-2 × BBSR-10-26 (1.91 kg). Thus, on the basis of per se performance, the F1 crosses viz. BBSR-08-2 × Selection from BBSR-145-1, BBSR-08-2 × BBSR-10-25 and BBSR-08-2 × BBSR-10-26 may be recommended for commercial cultivation. The parent Arka Neelanchal Shyama may be used as a parent to develop early variety in brinjal.

Published: April 2023

Kharif sorghum is an important crop of the northern transition zone (NTZ) of Karnataka. Historically this zone was characterized by the assured and uniform distribution of rainfall during the southwest monsoon. The last decade has witnessed increased erraticity in the onset, progress and distribution of rainfall, but days without rain also remain cloudy for weeks during Kharif season, thus lower the crop canopy, which affects the yield, interrupts solar radiation. Solar radiation, rainfall are the two important climatic factors affecting crop performance, but it is logistically difficult, and resource demanding to artificially create study-growing environment under field conditions. Alternately, Crop Simulation Models can be effectively used for such studies by creating customized weather scenarios within the model. Four rainfall scenarios (±10 and ±20 % over observed) and four solar radiation scenarios (±10 and ±20 % over observed) were created by using 32 years’ observed weather data (1985-2016) within the calibrated and validated DSSAT-CERES-Sorghum model [1].

Simulations were run across all the above scenarios for 32 years' seasonal analysis with the best four kharif sorghum cultivars sown across three dates of sowing under the standard package of practices followed for NTZ. Model simulated annual outputs for grain yield over 32 years were averaged and presented. The model simulated results revealed that for NTZ changes in solar radiation was found to have more effect on yield than rainfall. Any reduction in solar radiation over observed drastically reduces the yield. Across cultivars and dates of sowing under observed weather (1985-2016), on average, 1720 kg ha-1 yield was simulated. When solar radiation was reduced by 10 % across rainfall scenarios the average yield was reduced to 1424 kg ha-1 which further reduced to 670 kg ha-1 (61% reduction) when solar radiation was reduced by 20 %. In contrast, when solar radiation was increased by 10 % and 20 %, the model simulated 2967   kg ha-1 and 3181 kg ha-1 yield, respectively which is 42 and 46 % more over the yield of observed weather. This study showed that for NTZ of Karnataka during the Kharif season increased cloudy period will have a more adverse effect on yield than changes to rainfall.

Published: April 2023

The management of duodenal malignant lymphoma presents challenges due to the presence of serious complications like obstruction, pancreatitis, and perforation. As a result, a combination of surgical measures and interdisciplinary procedures is necessary.

We report a case of a 44 years old man suffering from abdominal pain and vomiting.

CT images showed a voluminous intraperitoneal perforated tumour.

Intra operative exploration showed that the origin of the tumour is duodenum, a resection was performed. Patient died few hours after surgery. Histological and immunohistochemical findings confirmed the diagnostic of burkitt lymphoma.

The primary treatment for gastrointestinal lymphomas remains chemotherapy, but in cases of duodenal lymphoma, a significant number of patients need surgery due to complicated presentations.

Background: Acute lymphoblastic leukemia (ALL) is cancer of lymphocytes, characterized by over production and accumulation of cancerous immature lymphocytes known as lymphoblasts. The purpose of this research was to estimate micRNA-326 and micRNA-200c expression in children with ALL before and after chemotherapy to explore their potential value in diagnosis and prognosis of pediatric ALL.

Methods: This case control researchwas conducted on 30 children with ALL (group I) and 10 healthy children with matched age and sex as controls (group II). All participants were subjected to history taking, clinical examination and laboratory investigations including routine investigations for cases and controls (CBC on ERMA PCE-210N cell counter, serum LDH, ESR assessment), investigations for cases only (bone marrow aspiration and examination of stained films, cytochemistry, and immunophenotyping) and specific laboratory test for cases and controls: MicRNA-326 and MicRNA-200c relative expression by quantitative-real time PCR at diagnosis and after one year of chemotherapy.

Results: MicRNA-326 and micRNA-200c relative gene expression levels were significantly down regulated in ALL cases than in control group. As regard ALL subtypes micRNA-326 was significantly down regulated in T-ALL cases than in B-ALL cases. While micRNA-200c was significantly down regulated in B-ALL cases than in T-ALL. After a year of chemotherapy for ALL cases, micRNA-326 and micRNA-200c expression levels were still down regulated in relapsed cases while upregulated in cured cases.

Conclusions: The present research showed a statistically significant lower expression of micRNA-326 and micRNA-200c in newly diagnosed ALL children and in relapsed cases after one year of chemotherapy. These data suggests that micRNA-326 and micRNA-200c may play a role in diagnosis, prognosis, and early detection of relapsed cases.

IMPORTANCE

Digital health applications have been shown to be effective in the management of chronic diseases with simple treatment targets. The potential clinical value of digital health applications in rheumatoid arthritis (RA) has not been well studied.

OBJECTIVE

To investigate whether assessing patient-reported outcomes using digital health applications could result in disease control for patients with RA.

DESIGN, SETTING, AND PARTICIPANTS

This is a multicenter, open-label randomized clinical trial in 22 tertiary hospitals across China. Eligible participants were adult patients with RA. Participants were enrolled from November 1, 2018, to May 28, 2019, with a 12-month follow-up. The statisticians and rheumatologists who assessed disease activity were blinded. Investigators and participants were not blind to group assignment. Analysis was conducted from October 2020 to May 2022.

INTERVENTIONS

Participants were randomly assigned at a 1:1 ratio (block size of 4) to a smart system of disease management group (SSDM) or a conventional care control group. Upon the completion of the 6-month parallel comparison, patients in the conventional care control group were instructed to use the SSDM application for an extension of 6 months.

MAIN OUTCOMES AND MEASURES

The primary outcome was the rate of patients with disease activity score in 28 joints using the C-reactive protein (DAS28-CRP) of 3.2 or less at month 6.

RESULTS

Of 3374 participants screened, 2204 were randomized, and 2197 patients with RA (mean [SD] age, 50.5 [12.4] years; 1812 [82.5%] female) were enrolled. The study included 1099 participants in the SSDM group and 1098 participants in the control group. At month 6, the rate of patients with DAS28-CRP of 3.2 or less was 71.0% (780 of 1099 patients) in the SSDM group vs 64.5% (708 of 1098 patients) in the control group (difference between groups, 6.6%; 95% CI, 2.7% to 10.4%; P = .001). At month 12, the rate of patients with DAS28-CRP of 3.2 or less in the control group increased to a level (77.7%) that was comparable with that (78,2%) in the SSDM group (difference between groups, −0.2%; 95% CI, −3.9% to 3.4%; P = .90).

CONCLUSIONS AND RELEVANCE

In this randomized clinical trial of RA, the use of a digital health application with patient-reported outcomes was associated with an increase in disease control rate.
