Abstract
—Based on the analysis of the petrographic and lithogeochemical features of the Middle Jurassic–Lower Cretaceous strata in the lower reaches of the Anabar River, we have studied the regularities of changes in the composition of the upper parts of the Yuryung-Tumus and Sodiemykha formations and the lower part of the Buolkalakh Formation. It has been established that the silt–sandy rocks of the first and basal beds of the second formation are graywacke arkoses and essentially feldspathic varieties, and most of the Sodiemykha Formation is composed of quartz–feldspathic and scarcer feldspar–quartz graywackes. A chemical classification of the rocks was made; most of them were assigned to normosiallites. The rocks of the marker beds, namely, the Fe-containing deposits of the Sodiemykha Formation, the basal glauconite bed of the Buolkalakh Formation, and the overlying clay bed, were classified as hypohydrolysates. All the studied deposits are of low sedimentary maturity, with essentially petrogenic clastic material. These are predominantly igneous rocks of intermediate and, less, felsic composition. The provenances were characterized by moderate chemical weathering. In the periods of the formation of the marker beds, chemical weathering intensified, and the amount of mafic and, partly, ultramafic rocks increased. The established changes in the composition of the parental strata are observed in the Middle Jurassic–Lower Cretaceous deposits of the entire considered petromineralogical province, which permits them to be used for correlation.

Abstract
—We present new data on the chemical composition of the late Precambrian rocks in the upper part of the regional Balaganakh stratigraphic horizon (the Nugan Formation at the Baikal segment of the Sayan–Baikal–Patom belt (SBPB) and the Bugarikhta Formation of the Balaganakh Group at the Patom segment of the SBPB) and the U–Pb (LA-ICP-MS) age of detrital zircons from the Bugarikhta Formation. It has been established that the rocks of the Nugan and Bugarikhta formations resulted from the destruction of igneous and metamorphic rocks. The contents and ratios of trace and rare-earth elements in the rocks of the Nugan and Bugarikhta formations indicate a predominance of felsic igneous rocks in the provenance and the presence of rocks of mafic and intermediate compositions at the source of the terrigenous rocks of the Nugan Formation. The U–Pb age of detrital zircons from all rocks of the upper part of the regional Balaganakh Horizon is close to the age of the rocks in the basement of the southern margin of the Siberian Platform, which suggests that this basement was the main source of clastic material in the sedimentation basins. It is argued that the “pre-glacial” (pre-Marinoan) terrigenous deposits of the Nugan and Bugarikhta formations, as well as the deposits of the Ipsit Formation at the Sayan segment of the SBPB, accumulated in the Late Riphean (ca. 720–640 Ma), probably in postrift basins that formed immediately after the separation of Siberia from Laurentia at the early stages of the opening of the Paleoasian Ocean.

Abstract
—The work deals with the development of methodological and algorithmic tools for the quantitative interpretation of oil well resistivity logs. We review the results of applying the neural-network-based approach to the inversion of resistivity logs measured at thinly bedded high-contrast environments. The capabilities of the proposed approach are demonstrated by the example of the algorithm for noninterative express inversion of unfocused lateral logs (BKZ). BKZ is the unfocused array logging method widely used in the Commonwealth of Independent States for oil well studies. BKZ logs are known for their complexity: The signals of unfocused gradient probes are highly affected by the medium properties below and above the measuring point. The developed algorithm is based on the inversion of full logs into the parameters of a 2D axisymmetric model of the medium, which allows naturally taking into account the influence of surrounding rocks and borehole conditions. Transition from the “layered” parametrization conventional for BKZ logs interpretation to a quasi-continuous change of properties along the well axis allows extracting meaningful information at every measurement point and constructing high-resolution geoelectric models of the sediments. The noniterative nature of the algorithm provides a high computing efficiency. This opens up the possibility of using the 2D inversion advantages to increase the reliability of the initial express interpretation results. Testing the algorithm on the practical data from West Siberian oilfields has revealed the field of its maximum efficiency, namely, study of impermeable and low-permeability sediments, such as the complex shaly caprocks and bituminous deposits of the Bazhenov Formation. With high-quality input data, the approach is also efficient for studying permeable terrigenous sediments.
Distribution of Hydrocarbon Resources by Fields of Different Sizes and by the Number of Pools in Each Field

Published: August 2022

Abstract
—This study describes a procedure for estimating the distribution of hydrocarbon resources by fields with different sizes of reserves and by the number of pools in each field. Such an evaluation is important in predicting the efficiency of exploration. The procedure first uses a simulation model for generating a population of hydrocarbon pool sizes. Then the spatial distribution of pools over a petroleum basin is modeled as a nonstationary Poisson point field. When we generate a field population in the basin, each field is considered a geometric object consisting of several pools according to the principle of their mutual geometric location. The proposed model was used to estimate a two-dimensional distribution of the number of fields and resources contained in them by resource sizes and the number of pools in each field. The proposed assessment was made for oil resources in the West Siberian petroleum province.

AbstractThe Denitrification-Decomposition (DNDC)-Rice is a mechanistic model which is widely used for the simulation and estimation of greenhouse gas emissions [nitrous oxide (N2O)] from soils under rice cultivation. N2O emissions from paddy fields in South Korea are of high importance for their cumulative effect on climate. The objective of this study was to estimate the N2O emissions and biogeochemical factors involved in N2O emissions such as ammonium (NH4+) and nitrate (NO3−) using the DNDC model in the rice-growing regions of South Korea. N2O emission was observed at every application of fertilizer and during end-season drainage at different rice-growing regions in South Korea. Maximum NH4+ and NO3− were observed at 0–10 cm depth of soil. NH4+ increased at each fertilizer application and no change in NO3− was observed during flooding. NH4+ decreased and NO3− increased simultaneously at end-season drainage. Minimum and maximum cumulative N2O emissions were observed at Chungcheongbuk-do and Jeju-do regions of South Korea, respectively. The simulated average cumulative N2O emission in rice paddies of South Korea was 1.37 kg N2O-N ha−1 season−1. This study will help in calculating the total nitrogen emissions from agriculture land of South Korea and the World.

Authors: Gollapalli Pavan , Selvan Gnanasekaran Tamizh , Rao Aditya S.J. , Manjunatha Hanumanthappa , Shetty Praveenkumar , Kumari Nalilu Suchetha 
Published: August 2022

Background:
The bioactive constituents from Zingiber officinale (Z. officinale) have shown
a positive effect on neurodegenerative diseases like Alzheimer's disease (AD), which manifests as
progressive memory loss and cognitive impairment.

Objective:
This study investigates the binding ability and the pharmaco-therapeutic potential of Z. officinale
with AD disease targets by molecular docking and molecular dynamic (MD) simulation approaches.

Method:
By coupling enormous available phytochemical data and advanced computational technologies,
the possible molecular mechanism of action of these bioactive compounds was deciphered by
evaluating phytochemicals, target fishing, and network biological analysis.

Results:
As a result, 175 bioactive compounds and 264 human target proteins were identified. The
gene ontology and Kyoto Encyclopaedia of Genes and Genomes pathway enrichment analysis and
molecular docking were used to predict the basis of vital bioactive compounds and biomolecular
mechanisms involved in the treatment of AD. Amongst selected bioactive compounds, 10-
Gingerdione and 1-dehydro-[8]-gingerdione exhibited significant anti-neurological properties against
AD targeting amyloid precursor protein with docking energy of -6.0 and -5.6, respectively.

Conclusion:
This study suggests that 10-Gingerdione and 1-dehydro-[8]-gingerdione strongly modulates
the anti-neurological activity and are associated with pathological features like amyloid-β
plaques and hyperphosphorylated tau protein are found to be critically regulated by these two target
proteins. This comprehensive analysis provides a clue for further investigation of these natural compounds'
inhibitory activity in drug discovery for AD treatment.
Efficacy and Conflicts of Interest in Randomized Controlled Trials Evaluating Headspace and Calm Apps: Systematic Review
Authors: O'Daffer Alison , Colt Susannah F , Wasil Akash R , Lau Nancy 
Published: August 2022

Background
Although there are thousands of mental health apps, 2 apps, Headspace and Calm, claim a large percentage of the marketplace. These two mindfulness and meditation apps have reached tens of millions of active users. To guide consumers, clinicians, and researchers, we performed a systematic review of randomized controlled trials (RCTs) of Headspace and Calm.

Objective
Our study aimed to evaluate intervention efficacy, risk of bias, and conflicts of interest (COIs) in the evidence base for Headspace and Calm, the two most popular mental health apps at the time of our search.

Methods
To identify studies, we searched academic databases (Google Scholar, MEDLINE, and PsycINFO) and the websites of Headspace and Calm in May 2021 for RCTs of Headspace and Calm testing efficacy via original data collection, published in English in peer-reviewed journals. For each study, we coded (1) study characteristics (eg, participants, sample size, and outcome measures), (2) intervention characteristics (eg, free vs paid version of the app and intended frequency of app usage), (3) all study outcomes, (4) Cochrane risk of bias variables, and (5) COI variables (eg, presence or absence of a preregistration and the presence or absence of a COI statement involving the company).

Results
We identified 14 RCTs of Headspace and 1 RCT of Calm. Overall, 93% (13/14) of RCTs of Headspace and 100% (1/1) of RCTs of Calm recruited participants from a nonclinical population. Studies commonly measured mindfulness, well-being, stress, depressive symptoms, and anxiety symptoms. Headspace use improved depression in 75% of studies that evaluated it as an outcome. Findings were mixed for mindfulness, well-being, stress, and anxiety, but at least 40% of studies showed improvement for each of these outcomes. Studies were generally underpowered to detect “small” or “medium” effect sizes. Furthermore, 50% (7/14) of RCTs of Headspace and 0% (0/1) of RCTs of Calm reported a COI that involved Headspace or Calm (the companies). The most common COI was the app company providing premium app access for free for participants, and notably, 14% (2/14) of RCTs of Headspace reported Headspace employee involvement in study design, execution, and data analysis. Only 36% (5/14) of RCTs of Headspace were preregistered, and the 1 RCT of Calm was not preregistered.

Conclusions
The empirical research on Headspace appears promising, whereas there is an absence of randomized trials on Calm. Limitations of this study include an inability to compare Headspace and Calm owing to the dearth of RCTs studying Calm and the reliance on author reports to evaluate COIs. When determining whether or not mental health apps are of high quality, identification of high-quality apps and evaluation of their effectiveness and investigators’ COIs should be ensured.

Published: August 2022

Some drugs give poor absorption because of a narrow absorption window in the gastrointestinal tract (GIT). To improve the absorption of such drugs in GIT, gastro retentive drug delivery techniques play a vital role. Lamivudine is an antiviral medicine. The floating gastroretentive microspheres were prepared to attain an extended therapeutic action of Lamivudine. Floating microspheres were formulated to prolong the gastric retention and enhancement of bioavailability of the drug candidate. The floating microspheres were formulated using guar gum and xanthan gum as natural polymers. The proposed floating system was evaluated by preliminary evaluation parameters, micrometric investigation as well as Particle size investigation, Percentage yield of microspheres, Drug entrapment efficiency, In-vitro drug release studies, and their kinetics. The formulated microsphere is evaluated in the form of its stable nature. The formulated microsphere was found to be smooth, spherical, and slightly aggregated containing guar gum whereas xanthan gum containing microsphere was found porous, irregular, grossly, and discrete globular. Formulated microsphere gives a good percentage of drug entrapment and practical yields. The floating microsphere prolonged the drug release by up to 12 hrs. The IR spectroscopy of the prepared formulation was shown that the chemical structure of the Lamivudine was unchanged. The prepared lamivudine microspheres presented gastro retentive and extended-release properties.
