Strategizing the Development Potential of the Russian Arctic: Import Phase-Out
Authors: Shmeleva Nadezhda
Published: March 2023

The current sanctions, pandemic, and geopolitical situation demand new strategies and models of territorial sustainable development. The article considers the theoretical and methodological aspects of the innovative and industrial potential of the Russian Arctic as part of the ongoing import phase-out. The development potential of this macroterritory depends on the implementation of its human, infrastructural, financial, and industrial potentials. The author developed a five-stage algorithm of balanced indicators that assess the industrial and innovative potential of a region and applied it to the Arctic regions of the Russian Federation. The regions that revealed a below-average potential were tested for bottlenecks and acquired a sevenfold strategy for sustainable development. The research facilitates the assessment, decision-making, strategizing, strategy implementation, and road-mapping of the Arctic economy. Territorial management based on high-performance decision support systems is able to improve the economic activity of the Russian Arctic, boost its macroeconomic indicators, and increase the local social standards.
Strategic Brand Transformation in Consumer Goods Industry and Fashion
Authors: Khvorostyanaya Anna
Published: March 2023

Strategic trends and patterns change the organizational, consumer, and instrumental landscape of the light industry and fashion companies. The current development of strategic branding is connected with the humanity (empathy) trend. In strategic branding, success depends on the right strategic decisions and customers’ feedback. Companies need to track consumer behavior, select relevant strategic communication tools, and create personalized propositions if they want to provide a sensitive response to customer preferences in real time. The present research objective was to identify effective strategic priorities in brand humanity in textile, footwear, clothing, and fashion. The task is relevant because brand humanity remains understudied in the spheres of light industry and fashion. The research relied on such traditional methods as analysis, synthesis, abstraction, generalization, and comparison, as well as on the theory and methodology of strategizing developed by V.L. Kvint, Doctor of Economics and a Foreign Member of the Russian Academy of Sciences. The paper introduces a strategic concept for brand humanity development. This model can provide companies with a new image and improve their reputation. The article also contains some methodological recommendations that can find practical application in the corporate brand development.

Automated object recognition of circular defects using infrared thermographic
Authors: Lee Seungju , Chung Yoonjae , Kim Wontae
Published: March 2023

Active infrared thermography is an attractive and reliable technique due to its non-contact, large-area, high-speed, qualitative and quantitative characteristics. In the lock-in infrared thermography, a lot of noise was generated due to non-uniform heat source excitation, so filtering was applied. The optimal excitation frequencyfor each amplitude and phasewas calculated using the ROI technique, and the automatic defect detection of circular defects was performed by applying the binarization processing algorithm.In this study, a mechanism that can perform clear defect detection in a very fast time was presented.

A simulation study into the effect of the defect type and excitation non-uniformity on the defect detectability with flash thermography
Authors: Poelman G , Hedayatrasa S , Kersemans M
Published: March 2023

Flash thermography is a valuable testing methodology to perform a rapid,full-field,non-destructive inspection. Many researchers have investigated the physical detection limits of flash thermography, however, those studies differ from one another in many ways (e.g. different defect properties). As such, it is difficult to combine their results into a general overview of the true defect detection limits in flash thermography. Therefore, the present authors have performed a parametric study into the defect detection limits of flash thermography using 3D finite element modelling. In this contribution, the influence of the defect type and excitation non-uniformity on the detection limits are discussed

Authors: Maillard S , Blouin V , Baillard A
Published: March 2023

In order to develop infrared inspection for aerospace sandwich components, a better knowledge of the key parameters of the process was required. Thus, analytic calculations were used to have a better understanding of acquisition and processing parameters. The results are analyzed and compared with elements given in the bibliography in the terms of amplitude, CNR and characteristics times on the curves. They allowed Safran to select the more suitable configuration to inspect composites panel and define acquisition parameters (energy deposited, acquisition duration,...) to be used regarding the material diffusivity and thickness
IR Thermal and UV imaging characterization of melanocytic lesions
Authors: Magalhaes C , Mendes J , Vardasca R
Published: March 2023

The deadliest form of skin cancer, melanoma, is frequently confused with its benign version, melanocytic nevus. Diagnosis is based on visual assessment, requiring commonly tumour excision for confirmation. Infrared thermal (IRT) imaging has shown its potential to assist diagnosis innocuously, but richer tissue characterization might be sustained with additional methods, as ultraviolet (UV) imaging. In this study, IRT and UV imaging were combined to assess 31 melanocytic lesions. Relevant differences were found for IRT parameters (up to 3◦C) being UV features also meaningful for lesion characterization (p-value≤0.05). Future application of findings would supply complementary information, assisting in harmless premature detection

Published: March 2023

Active thermography was used as a multispectral non-destructive approach for characterization of multi-layered panel paintings and analysis of their defects caused by aging and environmental effects. Twooil compositions painted on canvas, provided by C2RMF in the Louvre museum (Centre de Recherche et de Restauration desMusées de France) were under inspection. Active Thermography was demonstrated as being appropriate for the characterization of various defects on painting layers and the detection of under−drawings, pentimenti and canvas. Pulsed thermography system (PTvis setup of EDEVIS GmbH, provided by Thermoconcept) was applied to obtain and to inspect a dynamic thermal response, which was recorded by mid-and long-wavelength infrared TELOPS cameras. Control, synchronization and data analyses were made by EDEVIS DisplayImg Professional software (provided by Thermoconcept). In our studies, the combined approach provided by mid-and long-wavelength infrared cameras allowed us to obtain simultaneous complementary information on the painting specimen for its internal defects characterization and in situinspection

Authors: Amiel Stéphane , Clauzade Loïc , Gerardin Benoît , Zoukaghe Abdelhamid , Jenson Frédéric
Published: March 2023

During the manufacturing of metal turbine discs, fluorescent penetrant inspection is performed to detect surface defects. Because it does not use chemicals and allows the digitization of information, the infrared thermography is envisaged as an alternative method. The exploitation of the thermal response of the material to a laser excitation, measured with an infrared camera, allows the imaging of possible defects. The shape of the discs is adapted to the rotation of the part heated by a fixed laser line in the field of the thermal camera. The work described here is carried out for the industrialization of the process

Authors: Carvalho FCR , Menegaz GL , Barcelos AMC , Fernandes H , Guimarães G
Published: March 2023

Thyroid cancer is most common in the head-neck region. One of the most promising and non-invasive ways to identify this disease is thermography. The main objective of this work is to numerically simulate the process of bioheat transfer in the neck region, thus obtaining its temperature field and the behavior of its surface temperature. Parameters such as a fat layer, nodule size, blood perfusion, and metabolism are analyzed. Prior knowledge of the behavior of surface temperature as a function of these parameters is essential in applying thermal imaging for the detection of neck cancer
Signal Waveshape influence on the Impinging Synthetic Jets Flow Field and Heat Transfer
Authors: Paolillo G , Greco C S , Astarita T , Cardone G
Published: March 2023

Synthetic jets are jets generated by the periodic oscillation of an actuator,such as a loudspeaker, a piezoelectric membrane or a piston inside a cavity provided with an orifice or a nozzle. The fluid dynamic characteristics of the impinging synthetic jet flow field and the related heat transfer performances are strongly influenced by the waveshape of the electric signal driving the actuator. Therefore, two different classes of waveshapes have been considered: those obtained by varying the suction duty cycle factor and those obtained as Fourier series at a specified fundamental frequency

Authors: Wang Xiangtao , Wang Jianzhong , Yan Guangyu , Liu Xiaozhe , Huang Yue , Tian Suo , Xu Qingfa
Published: March 2023

In the process of geothermal tailwater reinjection of sandstone, the problem of plugging has been seriously restricting the continuous development of geothermal reinjection for many years, and the problems of plugging are complex and changeable. The plugging in the process of reinjection can be divided into physical plugging, chemical plugging, microbial plugging and gas plugging. Given these four types of blocking, according to the mechanism characteristics of the blocking caused by them, this paper puts forward corresponding blocking prevention measures and solves the current blocking problems by filtering, adding a scale inhibitor, intermittent reinjection, adding chlorine dioxide and regular lifting. In addition, the existing reinjection process and the equipment flow are relatively simple and cannot achieve the goal of efficient reinjection. Therefore, a complete set of reinjection processes is designed to ensure the efficient reinjection of sandstone geothermal tailwater.
NRSN2 is a Prognostic Biomarker in Gastric Cancer and Facilitates the
Growth and Migration of Gastric Cancer Cells
Authors: Ren Shenghui , Chen Manyu , Chen Yu , Ding Ke
Published: March 2023

Background:

Neurensin-2 (NRSN2) is reported to be associated with the progression of
many tumors. This work aimed at investigating the biological function and prognostic significance of
NRSN2 in gastric cancer (GC).

Methods:

NRSN2 expression in various cancer tissue was analyzed by the TIMER database. NRSN2
expression in GC tissue samples of different groups was analyzed by the UALCAN database. The
survival analysis was performed with the Kaplan-Meier database. NRSN2 expression in GC tissues
and cell lines was measured by qRT-PCR and Western blot. CCK-8, Transwell and scratch healing
assays were conducted to detect the proliferative, migrative and invasive capabilities of GC cells,
respectively. The LinkedOmics database and StarBase database were utilized to analyze the related
genes with NRSN2 in GC. The association of NRSN2 expression with tumor immune infiltrating cells
and molecular markers of immune cells was investigated with the TIMER database.

Results:

NRSN2 expression was up-regulated in GC tissues, which was correlated with GC tumor
grade, lymph node metastasis, and TP53 mutation. The prognosis of GC patients with high NRSN2
expression was worse than those of the patients with low NRSN2 expression. NRSN2 expression was
also associated with the TNM stage, and Lauren subtype of GC patients. NRSN2 overexpression
promoted the growth, migration and invasion of GC cells lines; knocking down NRSN2 worked
oppositely. NRSN2 expression in GC was associated with Wnt, p53, and NOD-like receptor signaling
pathways. NRSN2 expression was also significantly associated with the infiltration of CD8+ T cells,
CD4+ T cells, macrophages, neutrophils, and dendritic cells in the GC microenvironment.

Conclusion:

NRSN2 expression in GC tissues is up-regulated, which correlates with a poor prognosis
and immune cell infiltration of GC patients. NRSN2 facilitates the growth and aggressiveness of GC
cells, implying that it may be a diagnostic biomarker and therapy target for GC.
“Renalism” with Renin Angiotensin Aldosterone System Inhibitor Use in
Patients Enrolled in Trials for Heart Failure with Reduced Ejection Fraction
and Advanced Chronic Kidney Disease: A Systematic Review
Authors: Sudani Hussein Al , Shah Samir , Lo Kevin Bryan , Essa Hani , Wattoo Ammaar , Angelim Lucas , Brousas Sophia , Whybrow-Huppatz Isabel , Vellanki Shaitalya , Sankaranarayanan Rajiv , Rangaswami Janani
Published: March 2023

Introduction:

Angiotensin-converting enzyme inhibitors (ACEI), angiotensin receptor blockers
(ARB), angiotensin receptor-neprilysin inhibitor (ARNI), and mineralocorticoid receptor antagonists
(MRA) reduce mortality and hospitalizations in heart failure with reduced ejection fraction (HFrEF) but
their use is limited in advanced chronic kidney disease (CKD).

Methods:

We carried out a systematic review of studies on HFrEF and CKD patients. The mean overall
percentage of reported ACEI, ARB, MRA, and ARNI use, and the proportion of trials that included
patients with advanced CKD grades 4-5 (estimated glomerular filtration rate (eGFR) <15-30
ml/min/1.73m2) were recorded per year. The proportion of trials with advanced CKD was logtransformed,
and then fitted into a time regression model. The interactions between the proportion of
trials that included CKD grades 4-5 and the proportion of reported use of ACEI, ARB, and MRAs per
year were explored using Pearson’s correlation and univariate linear regression.

Results:

A total of 706 articles were included; 76% reported background ACEI/ARB use, while 51%
reported MRA use. ACEI/ARB use averaged 83% and MRA 50%. Of the trials, 57% included CKD
grades 4-5. Over 10 years, the proportion of trials with CKD grades 4-5 increased while ACEI/ARB use
decreased. MRA use rates remained about the same. There was an inverse association found between
the proportion of trials with CKD grades 4-5 and ACEI/ARB use per year.

Conclusion:

In the past 10 years, CKD grades 4-5 patients have been increasingly included in HFrEF
clinical trials. Concurrently, ACEI/ARB use has reportedly decreased.
Occurrence, Isolation, Pharmacological Potential, Metabolism, and Toxicity
of Myristicin: A Naturally Occurring Alkoxy-Substituted Allylbenzene
Authors: Kaur Vishaldeep , Kaushal Sonia , Heena  , Utreja Divya
Published: March 2023

Background:

Natural products are secondary metabolites obtained from plants, animals,
and microorganisms with diverse chemical structures resulting in diverse biological functions and
drug-like properties.

Objective:

This review article summarizes in detail the occurrence, detection, isolation, various
pharmacological properties, metabolism, and toxicity of a natural compound i.e., 5-Allyl-1-methoxy-
2,3-methylenedioxybenzene commonly known as Myristicin.

Methods:

A relevant literature search was made using the keywords essential oil, mace, myristicin,
nutmeg, and pharmacological activities from different databases such as PubMed, Sci Finder, Science
Direct, and Google Scholar. The literature search results presented articles from 1963 to 2022. Thereafter,
the articles were carefully screened and selected for review.

Results:

Myristicin, an alkoxy-substituted allylbenzene is present in major to minor amounts in the
essential oils obtained from different plant parts and exhibits various pharmacological properties such
as antimicrobial, antioxidant, antiproliferative, anti-inflammatory, insecticidal, and hepatoprotective.
It forms 10 metabolites by reduction, demethylation, hydroxylation, ring formation, ring-opening,
and conjugate formation. In the liver, myristicin has been metabolized by Cytochrome P450 complex
enzymes to generate active metabolite (1ˈ hyroxymyristicin) responsible for cytotoxic, genotoxic and
apoptotic effects (150 μM). But, myristicin at 600 μM does not produce enough 1ʼ-hydroxymyristicin
to give the final toxicant.

Conclusion:

Myristicin poses no major risk to human health through the consumption of herbs and
spices due to its presence in low amounts. It has great potential to be used in the traditional system of
medicine. We hope that this review will provide complete knowledge about myristicin on a single
platform.

Published: March 2023

Diabetes mellitus (DM), a chronic medical condition, has attained a global pandemic
status over the last few decades affecting millions of people. Despite a variety of synthetic drugs
available in the market, the use of herbal medicines for managing diabetes is gaining importance
because of being comparatively safer. This article reviews the result of a substantial literature
search on polyherbal formulations (PHFs) developed and evaluated with potential for DM. The accumulated
data in the literature allowed us to enlist 76PHFs consisting of different parts of 147
plant species belonging to 58 botanical families. The documented plant species are laden with bioactive
components with anti-diabetic properties and thus draw attention. The most favoured ingredient
for PHFs was leaves of Gymnema sylvestre and seeds of Trigonella foenum-graecum used in
27 and 22 formulations, respectively. Apart from herbs, shilajit (exudates from high mountain
rocks) formed an important component of 9 PHFs, whereas calcined Mytilus margaritiferus and
goat pancreas were used in Dolabi, the most commonly used tablet form of PHF in Indian markets.
The healing properties of PHFs against diabetes have been examined in both pre-clinical studies
and clinical trials. However, the mechanism(s) of action of PHFs are still unclear and considered
the pitfalls inherent in understanding the benefits of PHFs. From the information available based
on experimental systems, it could be concluded that plant-derived medicines will have a considerable
role to play in the control of diabetes provided the challenges related to their bioavailability,
bioefficacy, optimal dose, lack of characterization, ambiguous mechanism of action, and clinical
efficiency are addressed.

Authors: Akilie Muhammad Sudirman , Ashari Ulfira , Xyzquolyna Deyvie
Published: March 2023

Nutrizinc rice is a biofortified variety designed with the advantage of high specific nutritional value, especially at higher levels of zinc nutrition compared to Ciherang rice. The mineral zinc is useful for preventing stunting in humans, and to help protect the human immune system from the attack of the COVID-19 virus. However, this variety has just been promoted by The Assessment Institute for Agricultural Technology (AIAT, in Indonesian: Balai Pengkajian Teknologi Pertanian, BPTP) Gorontalo Province so people are still not familiar with this rice. Therefore, it is important to conduct research related to the analysis of the level of consumer acceptance aimed at knowing consumer preferences and attitudes towards the attributes of high-zinc nutritious rice. The study had 60 respondents who were chosen by chance (accidental). This study used Chi Square analysis (X2) to see the differences in consumer preferences for the attributes of high zinc nutritional rice with various cooking methods and the ratio between rice and water. Meanwhile, Fishbein Multi-attribute analysis was used to determine consumer attitudes towards the attributes of high-zinc nutritional rice. The results showed that the different methods of cooking and adding water to the rice did not significantly change the flavor, color, and aroma of the rice, on the contrary, it only changed the texture of the rice. The high-zinc nutritional rice that consumers like was rice that had a slightly sweet flavor, fluffier texture, bright white color, and has no odor. In addition, the color and texture attributes of rice with high zinc nutrition were the most dominant considerations compared to other attributes in deciding to buy or consume rice with high zinc nutrition.

Influence of the crystal substrate parameters on the maximum power of silicon heterojunction solar cells
Authors: Panaiotti I. E.
Published: March 2023

The effect of the donor impurity concentration and the lifetime of charge carriers in a crystalline silicon substrate on the maximum power of heterojunction thin-film solar cells is studied. The model used in the calculations takes into account the features of photocurrent generation under conditions of medium or high levels of injection of charge carriers at an arbitrary ratio between the diffusion length and the thickness of the semiconductor wafer. The proposed technique makes it possible, with sufficient accuracy for practical purposes, to calculate the permissible variation limits of the substrate parameters, which ensure the specified values of the performance characteristics of photoelectric converters. Keywords: heterojunction solar cells, crystalline silicon substrates, optimal parameters, maximum power.

Published: March 2023

Temperature response of a material to an external electric field is the main method for electrocaloric effect study in ferroelectrics. In this work, for 0.65PbFe2/3W1/3O3-0.35PbTiO3 solid solution as a model object, it is shown that with an increase in the electric field strength, current filamentation effect can occur. It leads to formation of local regions of increased conductivity in the sample. The associated thermal effect have short characteristic times, due to the small volume of the filament. They are comparable to the times of the electrocaloric response of the material, and can lead to significant errors in the detection of the electrocaloric effect. Keywords: electrocaloric effect, temperature response, ferroelectric ceramics, current filamentation effect.

Characterizing Consumer Smartphone Apps for Virtual Reality–Based Exposure Therapy: Content Analysis
Authors: Sunkara Charvi , Thakkar Rajvi , Ong Triton , Bunnell Brian E
Published: March 2023

Background

In vivo exposure therapy is the most effective treatment for phobias but is often impractical. Virtual reality exposure therapy (VRET) can help overcome critical barriers to in vivo exposure therapy. However, accessible mobile software related to VRET is not well understood.

Objective

The purpose of our study is to describe the landscape of accessible smartphone apps with potential utility for clinical VRET.

Methods

We conducted a content analysis of publicly available smartphone apps related to virtual reality on the Google Play Store and the Apple App Store as of March 2020.

Results

The initial search yielded 525 apps, with 84 apps (52 on the Google Play Store and 32 on the Apple App Store) included for analysis. The most common phobic stimulus depicted was bodies of water or weather events (25/84, 29.8%), followed by heights (24/84, 28.6%), and animals (23/84, 27.4%). More than half of the apps were visually abstract (39/84, 53.5%). Most apps were free to use (48/84, 57.1%), while the rest were free to try (22/84, 26.2%) or required payment for use (14/84, 16.7%), with the highest cost for use being US $6. The average overall app rating was 2.9 stars out of 5, but the number of ratings ranged from 0 to 49,233. None of the 84 apps advertised compliance with the Health Insurance Portability and Accountability Act, offered the ability to monitor data, provided clinician control over variables in the app experiences, or explicitly stated use by or development with clinicians.

Conclusions

None of the smartphone apps reviewed were explicitly developed for phobia therapy. However, 16 of the 84 included apps were considered ideal candidates to investigate further as part of treatment due to their accessibility, depiction of phobia-relevant stimuli, low or no cost, and high user scores. Most of these apps were visually abstract and free to use, making them accessible and potentially flexible as part of clinical exposure hierarchies. However, none of the apps were designed for clinical use, nor did they provide tools for clinician workflows. Formal evaluation of these accessible smartphone apps is needed to understand the clinical potential of accessible VRET solutions.
The Effect of Clinical Decision Prompts in Improving Human Papillomavirus Vaccination Rates in a Multispecialty Practice in a Predominantly Hispanic Population: Quasi-Experimental Study
Authors: Molokwu Jennifer , Mendez Melissa , Bracamontes Christina
Published: March 2023

Background

The human papillomavirus (HPV) is implicated in the causal pathway of cancers of the vulva, vagina, penis, cervix, anus, and oropharyngeal region. It is the most common sexually transmitted infection in the United States. Despite the documented safety and effectiveness of the HPV vaccine, rates lag behind those of other vaccines given at the same age.

Objective

Provider recommendation is identified as a robust predictor of HPV vaccine uptake, and physician-prompting is shown to increase the provision of preventive care services in general. Theoretically, providing reminders to providers should increase opportunities for providing HPV vaccine recommendations and therefore affect vaccination rates. The objective of our study was to assess the effectiveness of an electronic medical record (EMR) prompt in improving HPV vaccination rates in an academic clinic setting caring for a predominantly Hispanic border population.

Methods

We used a quasi-experimental design with a retrospective chart audit to evaluate the effect of a clinical decision prompt (CDP) on improving HPV immunization rates in different specialty settings. We introduced an EMR prompt to remind providers to recommend the HPV vaccine when seeing appropriate patients in an obstetrics and gynecology (OBGYN), pediatrics (PD), and family medicine (FM) clinic in a large multispecialty academic group located along the Texas-Mexico border. We assessed HPV vaccination rates in all the departments involved before and after introducing the prompts. Participants included male and female patients between the ages of 9 and 26 years, presenting at the clinics between January 2014 and December 2015.

Results

We reviewed over 2800 charts in all 3 clinics. After adjusting for age, ethnicity, race, type of insurance, preferred language, and clinic, the odds of immunization were 92% (P<.001) higher in patients after the prompt implementation of the EMR. In addition, there was an overall statistically significant increase in the overall HPV vaccination completion rates after implementing the CDP (31.96% vs 21.22%; P<.001). Again, OBGYN saw the most significant improvement in vaccination completion rates, with rates at follow-up 66.02% higher than baseline rates (P=.04). PD and FM had somewhat similar but no less impressive improvements (57.7% and 58.36%; P<.001).

Conclusions

Implementing an EMR CDP improved our overall odds of HPV vaccination completion by 92%. We theorize that the decision prompts remind health care providers to discuss or recommend the HPV vaccination during clinical service delivery. CDPs in the EMR help increase HPV vaccination rates in multiple specialties and are a low-cost intervention for improving vaccination rates.

Journalists are among the workers who continue to engage in journalism activities like news covering despite the COVID-19 pandemic. Journalists facing paradoxical conditions between being productive in news covering and the dangers of virus transmission that can infect at any time. In other hand, journalists need support equipment facilities to avoid virus transmission during news covering process. Moreover, various media companies announce layoffs and salary cuts by asserting business uncertainty. This study aims to describe journalists’ vulnerability within journalism activity and journalist as occupation during the COVID-19 pandemic in 2020. This study was conducted with a qualitative method by analyzing the primer data from 50 journalist various region and representatives of journalist’s association in Indonesia. Furthermore, we analyze secondary data that provided officially by Alliance of Independent Journalists Indonesia. Authors found that the lack of health insurance, support for preventing the spread of COVID-19, unilateral dismissals by media institutions, and salary cuts place journalists in a difficult position. Aspects of journalism activities that run normally without institutional or structural support legitimize the vulnerabilities experienced by journalists in Indonesia.

Published: March 2023

At the present time, cardiovascular disease (also known as CVD) is one of the primary causes of death. In recent years, regenerative medicine, tissue engineering, and the development of novel materials have been the primary focuses of this field of study. Recently, the public's interest has been piqued by the use of electrospinning technology to produce nanofibrous materials for the treatment of cardiovascular diseases. The production of nanofibers may be accomplished in an easy and versatile way with the use of electrospinning. In this article, we will go through a number of different biodegradable polymers that may be used for the manufacturing of fibers. In addition, we provide the most recent information about the use of nanofibers in the management of myocardial infarction. This analysis comes to a close with a review of the limitations of the technology, its potential future applications for treating cardiovascular illness, and the technical challenges it faces.

Published: March 2023

Objective: The present investigation was undertaken to prepare polymeric nanosponges of an anti-cancer drug, ibrutinib to achieve controlled and improved drug release.
Methods: Nanosponges using a polymer (ethyl cellulose, poloxamer 188 and eudragit RL 30 D) and polyvinyl alcohol as a cross-linker were prepared successfully by the emulsion solvent evaporation method. Prepared nanosponges were evaluated for particle size, zeta potential, entrapment efficiency and in vitro drug release. Nanosponges with good drug release were formulated into tablets and evaluated for miromeritic properties, post-compression parameters and in vitro release and the final optimised formulation was characterized for globule size, zeta-potential, FTIR, SEM and stability studies.
Results: The nanosponges' particle sizes were discovered to range between 86.31 nm and 162.4 nm, the Zeta Potential ranges from-22.1 to-29. It was discovered that the drug entrapment efficiency ranged from 92.21 to 99.23% and Formulation F18 exhibited the highest drug release rate of 99.73% in 12h and was discovered to demonstrate good, satisfying results. The tablet formulation's micromeritic and post-compression parameters were examined, and it was discovered that F18 had good flow qualities. F18 had a mean globule size of 133.6 nm, a zeta potential of-22.1 mV, and SEM images revealed a sphere-like structure. The complexation of ibrutinib and the amorphous condition of the medication and formulation were confirmed by the FT-IR, and stability investigations to be stable for three months.
Conclusion: Hence, Ibrutinib loading into nanosponges made using the emulsion solvent evaporation process thus successfully boosted and controlled the drug release.

Objective: Present study aimed to develop and validate a novel, unique, simple, quick, cost-effective, sensitive, specific, accurate, precise, rugged, and robust bioanalytical method for the quantification of gallic acid in rat plasma by reverse phase high-performance liquid chromatography (RP-HPLC) using gradient elution technique.
Methods: The stationary phase was a Zorbax SB C18 5 µ (4.6*150) mm column, with the mobile phase being water with 0.1 percent formic acid (A): acetonitrile (ACN) with 0.08 percent formic acid (B). Gradient chromatographic method was used throughout this experiment from the point of view of the estimation of gallic acid from herbal formulations when present along with other phytoconstituents. So at the gradient method, all the present phytoconstituents has cleared off from the column and no any strongly adsorption of phytoconstituents occurred. The experiment was carried out at a flow rate of 1.0 ml/min at 30 °C utilising PDA detectors at 271 nm. The proposed method was validated for different parameters.
Results: The approach was found to be linear in the concentration range of 0.5-100 µg/ml, with a r2 of 0.9998. There was not observed any interference of co-eluting peaks of endogenous compounds from the biological matrix at the same retention time (Rt) of gallic acid. The RSD (%) of intra and interday precision was found to be within acceptable limit. The overall % mean recovery was found to be 99.97%. LOD and LOQ were found to be 0.1 and 0.5 μg/ml, respectively. In terms of fluctuation in essential parameters and operating settings, the devised bioanalytical approach was shown to be rugged and resilient. Short-term, long-term, autosampler, bench-top, and freeze-thaw stability experiments revealed that gallic acid is stable.
Conclusion: The developed method described in this report was found to be well within an acceptable range. Hence, in the future, this method can be used successfully for the estimation of gallic acid alone or in combination with another analyte or marker present in bulk or an extract containing various phytoconstituents in pharmacokinetic, bioequivalence, and therapeutic drug monitoring studies in clinical laboratories.
