Background: Existing reviews of pre-eclampsia determinants have
focused on clinical and genetic risk factors. Objective: To
evaluate social determinants for pre-eclampsia prevention.
Search strategy: Systematic searches were conducted on relevant
electronic databases to 31 July 2023.
Selection criteria: Reviews and large cohort studies (≥1,000
participants), published within the last 10 years, reporting
quantitative associations between social determinant exposures and
pre-eclampsia outcomes. Data collection and analysis: Titles
and abstracts and then relevant full-texts were reviewed by two
reviewers, independently. Strength of association was evaluated as
‘definite’ (odds ratios [OR] or relative risk [RR] ≥3.00 or
<0.33), ‘probable’ (OR or RR 1.50-2.99 or 0.33-0.67),
‘possible’ (OR or RR 1.10-1.49 or 0.68-0.89), or ‘unlikely’ (OR or RR
0.90 - 1.09). Quality of the evidence was high, moderate, low, or
very-low, using GRADE. Main results: Twenty-six publications
found 22 associations of pre-eclampsia with socioeconomic status, social
support/exclusion, healthcare access, and occupational and physical
environmental factors. One association (polygamy) was definite
(low-quality evidence). Probable associations included: work stress and
lack of antenatal care (high-quality evidence); prolonged occupational
exposure to whole body vibrations or bending, elevated temperatures
beyond seasonal norms, and UV-B radiation exposure (protective factor),
all based on moderate-quality evidence; and Asian/Oceanian origins
(protective, low-quality evidence). There were 11 possible associations,
which did not include education. Conclusion: Our findings
support recommendations to address climate change, strengthen
occupational protection, and promote early ANC attendance. Social
determinants may be indicative of upstream factors (e.g., obesity) that
increase likelihood of clinical risk factors for pre-eclampsia incidence
and severity.
Copper-catalyzed intramolecular cyclization synthesis of 2-hydroxy-indolin-3-ones: a combined experimental and theoretical study
Authors: Ma Haojie , Zhou Fengyuan , Li Yuqi , Zhang Yuqi , Huang Guosheng , Yang Xing , Wang Ji-Jiang
Published: May 2024

The synthesis of substituted 2-hydroxy-indolin-3-ones has attracted
considerable attention of synthetic chemists because they present in
numbers of natural products and biologically active molecules. Herein, a
novel and convenient copper-catalyzed oxidative intramolecular
cyclization of N-(2-acetylphenyl)picolinamide for the synthesis of
2-hydroxy-indolin-3-ones has been developed. Moreover, the detailed
mechanism presented is supported by control experiments and density
function-al theory calculations. This method provides direct access to
2-hydroxy-indolin-3-ones in high yield and good functional group
tolerance. Atom-economy, avoidance of the preparation for substrates and
step economy make this protocol be practical. This strategy provides an
alternative synthetic method to ex-plore the synthetic application of
various types of 2-hydroxy-indolin-3-ones and their enantiopure
deriv-atives.
The role of the posterior intralaminar thalamic nucleus on contact sequence in mouse social interaction
Authors: Arakawa Hiroyuki , Tokashiki Mana
Published: May 2024

Efficient social interaction is essential for an adaptive life and
consists of sequential processes of multisensory events with social
counterparts. Social touch/contact is a unique component that promotes a
sequence of social behaviors initiated by detection and approach to
assess a social stimulus and subsequent maintenance of touch/contacts to
form prosocial relationships. We hypothesized that the thalamic sensory
relay circuit from the posterior intralaminar nucleus of the thalamus
(pIL) to the paraventricular nucleus of the hypothalamus (PVN) and the
medial amygdala (MeA) plays a key role in the social contact-mediated
sequence of events. We found that neurons in the pIL along with the PVN
and MeA, were activated by social encounters, and that pIL activity was
more abundant in a direct physical encounter, whereas MeA activity was
dominant in an indirect via grid encounter. Chemogenetic inhibition of
pIL neurons selectively decreased the investigatory approach and
sniffing of a same-sex, but not an opposite-sex, stimulus mouse in an
indirect encounter situation and decreased the facial/snout contact
ratio in a direct encounter setting. Furthermore, chemogenetic pIL
inhibition had no impact on anxiety-like behaviors or body coordinative
motor behaviors, but it impaired whisker-related and plantar touch
tactile sense. We propose that the pIL circuit can relay social tactile
sensations and mediate the sequence of non-sexual prosocial interactions
using an investigatory approach through tactile contact.
Long-term opioid therapy and risk of opioid overdose by derived clinical indication in North Carolina, 2006-2018

Published: May 2024

Purpose: Long-term opioid therapy (LTOT) has been shown to be
associated with opioid overdose, but the definition of LTOT varies
widely across studies. We use a rigorous LTOT definition to examine risk
of opioid overdose by duration of treatment. Methods: Data were
from a large private health insurance provider in North Carolina linked
to mortality records from 2006-2018. Eligible patients were adults
(18-64) newly initiating opioid therapy after a pain diagnosis or
surgery. We defined LTOT as ≥1 opioid prescription per month totaling
≥60 days’ supply within 90 days. We used inverse probability- (IP)
weighted cumulative incidence functions to estimate three-year risk of
opioid overdose and IP-weighted Fine-Gray models to estimate
subdistribution hazard ratios, comparing LTOT to short- to medium-term
opioid therapy (SMTOT). We also examined modification by derived
indication of acute pain or surgery versus chronic pain.
Results: We identified 491,369 patients, and 1.7% were exposed
to LTOT. The three-year risk of opioid overdose was 0.3 percentage
points (RD = 0.003, 95% CI: 0.001, 0.005) higher in
LTOT patients compared to patients with SMTOT. The weighted hazard of
opioid overdose was 4.4 times as high (HR 4.42, 95%
CI 2.41, 8.11) among patients exposed to LTOT versus SMTOT. We did not
find meaningful modification by clinical indication for opioid therapy.
Conclusions: Exposure to LTOT was associated with increased
risk of opioid overdose in this population of privately insured patients
using a rigorous definition of LTOT. These findings confirm the
importance of guidelines to minimize duration of opioid therapy whenever
possible.
Impact of Arctic and Antarctic Sudden Stratospheric Warmings on Thermospheric Composition
Authors: Zhang Jiarong , Oberheide Jens , Pedatella Nicholas M , Liu Guiping
Published: May 2024

Using the Global-scale Observations of the Limb and Disk (GOLD) and the
Global Ultraviolet Imager (GUVI), we examine the impact of sudden
stratospheric warmings (SSWs) on the changes of thermospheric
composition during the 2018-2019 and 2020-2021 Arctic SSWs and the 2019
Antarctic SSW. Contributions of planetary waves, gravity waves, and
migrating tides are assessed by performing numerical experiments with
the NSF National Center for Atmospheric Research (NCAR) vertically
extended version of the Whole Atmosphere Community Climate Model
(WACCM-X). The wind evolution simulated in WACCM-X aligns well with the
quasi-geostrophic wind derived from Sounding of the Atmosphere using
Broadband Emission Radiometry (SABER) geopotential height measurements
during Arctic and Antarctic SSWs. The variations in column integrated O
and N density ratio (∑𝑂/N) are
generally similar among WACCM-X, GOLD, and GUVI observations. Following
the onset of SSWs, ∑𝑂/N is reduced by
~10% over 50°S-50°N and enhanced by
~20% at higher latitudes. The
∑𝑂/Nchanges are associated with the reversals of the
mean meridional circulation in the lower thermosphere, mainly driven by
westward-travelling planetary waves. The results highlight that
planetary wave activity during SSWs can significantly impact the mean
state of the thermosphere.

Authors: Chen Hailong , Wu Feifei , Kang Jing , Lian Bing
Published: May 2024

The radiological assessment model REIA 1.0 is established to assess the
radio-logical environmental impact of radioactive airborne effluents
released from nuclear fuel cycle facilities. It is based on the double
Gaussian probability distribution function model and considers the wind
pendulum effect of the long-term diffusion factor. The simulation results
of the REIA 1.0 model are compared with those of the AERMOD-VIEW model and
radiation environmental monitoring results of nuclear fuel cycle
facilities. The results are: using the REIA 1.0 and AERMOD-VIEW models, the
relative deviations of simulation results are less than 33.33% in 192
subregions. Except for three points, the relative deviations are less than
20%, the simulated results are consistent with the radiation environmental
monitoring results in seven sites using the REIA 1.0 model, and the REIA 1.0
model can characterize the incremental contribution of radionuclide
concentration in the air caused by the radioactive airborne effluents from
nuclear fuel cycle facilities. It can effectively assess the radiological
environmental impact of nuclear fuel cycle facilities.

Authors: Jiang Ai-Feng , Chen Yu
Published: May 2024

Using first-principles calculations, the mechanical properties of
orthorhombic phase Al1-xTMxP (x = 0.0625, 0.125, 0.25; TM = Sc, Ti, V, Cr,
Mn, Fe, Co, Ni, Cu, and Zn) crystals were studied. By analyzing the
mechanical stability, it was found that Al0.75Zn0.25P is mechanical
unstable, and the rest all mechanical stable. The mechanical properties of
Al1-xTMxP were studied, including Bulk modulus, shear modulus, Young?s
modulus, Poisson?s ration, ductility, Vickers hardness, and elastic
anisotropy. It was found that Al0.75Ni0.25P has the largest Bulk modulus,
the largest Poisson?s ratio. Al0.75Ni0.25P has the smallest shear modulus,
the smallest Young?s modulus and the smallest Vickers hardness. The
Al0.75Ni0.25P has the best ductility. Al0.75Ni0.25P and Al0.75Cu0.25P show
strong elastic anisotropy, and the Al0.75Cu0.25P has the largest elastic
anisotropy. Through the study of the mechanical properties of Al1-xTMxP, it
was found that doping Ni into AlP is an effective means to tune its
mechanical properties.

Published: May 2024

China's aging population is becoming more and more serious, which has a
far-reaching influence on the state and society. As the more elderly
population grows, it is necessary to strengthen a sound policy system to
alleviate the burden on families and society. The importance of accurately
predicting the elderly population is therefore highlighted. With the aim of
exploring the future development trend of China's older population, in this
paper, we establish a new fractional gray prediction model based on time
power term to study China's elderly population. We used data from 2010 to
2019 to assess modeling accuracy, demonstrating that the model outperforms
the other models. The final step is to use the model to forecast China's
elderly population from 2020 to 2029.

Published: May 2024

The available potential energy of the diurnal internal tide in the Northwest
Pacific ocean is studied by using short-term high-frequency mooring
observations. The results show that in the upper layer of the ocean, its
distribution is relatively chaotic, and it is greater between 1500-1600 m
and 2500-3000 m in the middle layer of the ocean. At other depths, it is
generally smaller, especially, at the bottom layer of the ocean, it is
relatively small. This paper concludes that the marvel of measurement is the
best science picks.
Do sex, age, and comorbidities modify the association of socioeconomic status and opioid use after total hip arthroplasty?: a population-based study from the Danish Hip Arthroplasty Register
Authors: Klenø André S , Mechlenburg Inger , Gademan Maaike G J , Sørensen Henrik T , Pedersen Alma B
Published: May 2024

Background and purpose: We aimed to examine the association between socioeconomic status (SES) markers and opioid use after primary total hip arthroplasty (THA) due to osteoarthritis, and whether sex, age, or comorbidities modify any association.Methods: Using Danish databases, we included 80,038 patients undergoing primary THA (2001–2018). We calculated prevalences and prevalence ratios (PRs with 95% confidence intervals [CIs]) of immediate post-THA opioid use (≥ 1 prescription within 1 month) and continued opioid use (≥ 1 prescription in 1–12 months) among immediate opioid users. Exposures were individual-based education, cohabitation, and wealth.Results: The prevalence of immediate opioid use was ~45% in preoperative non-users and ~60% in preoperative users (≥ 1 opioid 0–6 months before THA). Among non-users, the prevalences and PRs of continued opioid use were: 28% for low vs. 21% for high education (PR 1.28, CI 1.20–1.37), 27% for living alone vs. 23% for cohabiting (PR 1.09, CI 1.04–1.15), and 30% for low vs. 20% for high wealth (PR 1.43, CI 1.35–1.51). Among users, prevalences were 67% for low vs. 55% for high education (1.22, CI 1.17–1.27), 68% for living alone vs. 60% for cohabiting (PR 1.10, CI 1.07–1.12), and 73% for low wealth vs. 54% for high wealth (PR 1.32, CI 1.28–1.36). Based on testing for interaction, sex, age, and comorbidity did not statistically significant modify the associations. Nevertheless, associations were stronger in younger patients for all SES markers (mainly for non-users).Conclusion: Markers of low SES were associated with a higher prevalence of continued post-THA opioid use. Age modified the magnitude of the associations, but it was not statistically significant.
Therapeutic Properties of Lactic Acid Bacteria
Authors: T Kilic
Published: May 2024

Lactic acid bacteria (LAB) are considered a significant member of the human and animal intestinal microbiota due to their effects on host health, such as regulating the balance of the human and animal gastrointestinal microbiota. Thus, microecological balance can be maintained, and microbial infections can be prevented. In addition, LAB are used in bioprotective cultures to prevent spoilage and pathogenic microorganisms in the food industry. The therapeutic agents possessed by LAB include metabolites containing antibacterial, antifungal, antiviral, antioxidant, anticancer, immunomodulatory, and anti-inflammatory properties. Lactobacillus and Lactococcus may have potential therapeutic properties. In conclusion, LAB are commonly used in several industries, including food, clinical, agricultural, and animal husbandry. This Review aims to summarize the therapeutic properties of LAB, including recombinant and antimicrobial. LAB metabolites with therapeutic properties may be an alternative strategy to antibiotics in controlling infections, or these metabolites may be used synergistically with antibiotics. Additionally, this Review presents the advantages of LAB's therapeutic properties.

Authors: Amarapalli Geetha
Published: May 2024

The experiment was conducted during July–November, 2019 at Regional Agriculture Research Station, Professor Jayashankar Telangana State Agricultural University, Palem, Nagarkurnool district, Telangana State, India. The main treatments had five red gram genotypes and water stress levels were taken as sub-treatment in 3 replications in factorial RBD using specialized root structure made with cement bricks. There was great variability in the yield performance of different Redgram genotypes under drought conditions. The experiment was conducted to select genotypes with efficient root architecture and associated traits under drought stress.  Root studies were performed with the Delta T automatic root scanner. The SPAD chlorophyll meter was used to measure the SCMR value. The present study results revealed that genotype, Maruti showed significant superiority for character plant height and SCMR under non-stress, mild stress and severe stress conditions. The same genotype showed superior values for main root length under control and mild stress. Whereas, Laxmi recorded the highest plant height under severe stress and the same genotype also showed significant superiority for total plant dry weight, root dry weight and root area under severe stress. The genotype Laxmi showed significant character, root area and diameter superiority under mild stress.  ICPL-20176 recorded significant superiority for main root length under severe stress and root tip for mild stress. The identified genotypes can be used as the parents in future drought-proof breeding useful for cultivating in water stress conditions.

THE ROLE OF TEACHERS IN TRANSACTIONAL AND TRANSFORMATIONAL LEARNING
Authors: Askar
Published: May 2024

The main focus of the research is to describe the main concepts of transactional learning and transformational learning. Research was carried out through literature studies, with data collection using a "thematic" or "conceptual categories" approach where the results of the study of various references were organized according to topics or issues. The results of the research show that in transactional learning, the existence of the teacher has complete authority, occupies a central position, has advantages and knows everything, while students are in a position of not knowing, and therefore learning is indoctrinative, top down, centralized, prioritizing intellectual aspects, success learning is measured on the knowledge mastered by students cognitively. Transformative learning places greater emphasis on social and cultural transformation in students, so that they have the ability and insight to face and solve problems. The existence of teachers in transformative learning is actually parallel to the existence of students. Teachers and students are learning subjects and the object is reality. Transformative learning places dialogue as the main method in learning, and therefore the existence of teachers and students learn from each other.

Abstract
Pakcoy (Brassica rapa L.) is one of the essential vegetables in Asia. Light emitting diode (LED) can manipulate sunlight by providing red and blue LED colors. The red-blue LED light color is used to accelerate photosynthesis. This research was conducted to determine the irradiation of red-blue LEDs duration to produce the best pakcoy growth. The study used a completely randomized design (CRD) with 5 (five) irradiation treatments, ranging from 18, 16, 14, 12, and 10 hours. Parameters observed include plant height, canopy area, number of leaf blades, amount of chlorophyll content (SPAD value), fresh weight of harvest, biomass, and root length. The results showed that 18 hours of red and blue LED irradiation was the best result compared to other treatments. Eighteen hours of red-blue LED irradiation duration showed the best results compared to other treatments. This treatment had an average plant height of 17.4 cm, a number of leaf blades of 11.5 strands, an amount of chlorophyll content of 43.7 units, a root length of 28 cm, fresh weight of canopies and roots of 18.25 and 0.95 grams, and trunk and root biomass were 1.21 and 0.250 grams. In summary, the growth with prolonged irradiation of red-blue LEDs has a significant effect on the growth of pakcoy.
