Published: June 2024

Abstract
The current work aims to develop a new composite-based epoxy doped with calcinated clay for low and intermediate gamma-ray energy applications. The increased calcinated clay material concentration between 0 and 60 wt% enhances the constructed composites by 21.07%, from 1.139 ± 0.011 to 1.379 ± 0.013 g·cm−3. Moreover, new bonds have appeared in Fourier transform infrared analyses of fabricated composites, which confirm the diffusion and interactions between the calcinated clay material and epoxy resin. Furthermore, the impacts of the calcinated clay on the gamma-ray shielding properties were examined experimentally using the NaI (Tl) detector over an energy interval changing from 33 to 1,408 keV. The experimental examinations depict that the addition of calcinated clay with concentrations between 0 and 60 wt% enhances the developed composites’ linear attenuation coefficient by 67.9%, 24.5%, 35.9%, and 46.0% at gamma-ray energies of 81, 662, 1,275, and 1,408 keV, respectively. The improvement in the linear attenuation coefficient leads to a decrease in the required half-value layer for each composite, where it decreased between 4.82–3.87 cm (at 662 keV) and 7.63–5.22 cm (at 1,408 keV).

Abstract
The plans and activities of academic libraries revolve around a user-centered approach to make noticeable improvements in the use of library resources and services. The purpose of this study was to examine library support strategies for the effective utilization of library support services and resources by distance-learning students. The research was conducted at the University of Education, Winneba, and the University of Cape Coast with distance learning students. A mixed-method approach was used, with 1170 students participating in quantitative research and 12 students and six (6) librarians participating in qualitative research, with Astin’s (1993) Input-Environment-Output Model guiding the study. The findings of the study identified a lack of organized strategies for the use of library resources and services among distance learning students. The study proposed a model to improve the use of library resources and services among distance learning students.

Abstract
In this work, we define the notions of Wronskian and simplified Wronskian for Stieltjes derivatives and study some of their properties in a similar manner to the context of time scales or the usual derivative. Later, we use these tools to investigate second-order linear differential equations with Stieltjes derivatives to find linearly independent solutions, as well as to derive the variation of parameters method for problems with

Mais do que nunca, as propostas de ensino da Arte em sala de aula na atualidade devem seguir uma estreita relação com produções audiovisuais diversas, não somente no fazer em si, mas em sua leitura, contextualização e apropriação imagética por parte do Arte/Educador e de seus estudantes. Com isso, o presente artigo, a partir de produções gráficas e pictóricas de um estudante do pesquisador (que ora podem ser confundidas com um ensaio poético e/ou ensaio visual), pretende propor um passeio sobre o texto e as imagens dispostas com uma reflexão estendida que privilegie o olhar às produções audiovisuais, especificamente e principalmente animações como Naruto, enquanto arcabouço criativo que estende as experiências de seus espectadores para além das vivenciadas cotidianamente, pautando-se não somente na realidade, conformando memórias e impulsionando ações criativas. Trata-se de uma abordagem baseada em pesquisa bibliográfica, audiovisual e de campo, com o acervo de desenhos coletados um pouco mais de dois anos pelo pesquisador.
Breast Panel Biomarker Changes After Neoadjuvant Chemotherapy in Breast Cancer
Authors: Godoy Kris Raychelle , Madrid Manuelito 
Published: June 2024

Objectives. The aim of this study is to evaluate the breast panel biomarker changes and tumor intrinsic subtype after neoadjuvant chemotherapy among patients with residual invasive breast carcinoma whose breast specimens were processed at St. Luke’s Medical Center - Quezon City SLMC-QC) from 1 January 2017 to 30 June 2023.
Methodology. Cases of residual invasive breast carcinoma status post neoadjuvant systemic therapy were identified by retrospective review of cases. The baseline characteristics, type of biopsy and resection procedures, pre – and post–neoadjuvant ER, PR and HER2 status and pre – and post–neoadjuvant tumor intrinsic subtype were analyzed using frequency and percentage. The comparison of the changes in pre- and post-neoadjuvant breast panel biomarkers were analyzed by using McNemar test while the changes in the intrinsic tumor subtype was done using Wilcoxon signed-rank test.
Results. This study encompassed a total of 43 cases of residual invasive breast carcinoma following neoadjuvant systemic therapy. The data disclosed shifts in the breast molecular profile and intrinsic subtype post-administration of neoadjuvant systemic therapy. The alterations in hormone receptor status, ER and PR, were observed in 11.6% of cases, while HER-2 status exhibited changes in 2.3%. A 14% change in the tumor intrinsic subtype is observed. Among the initial 18 Luminal A cases, 1 transitioned to Luminal B, and among the 6 Luminal B cases, 2 become HER2 enriched subtypes. Furthermore, among the initial 12 HER2 enriched cases, three shifted to Luminal B, while all triple-negative cases remained unchanged after chemotherapy.
Conclusion. Based on our findings, alterations in the molecular profile of breast tumors, including shifts in intrinsic subtype after neoadjuvant chemotherapy (NAC), could impact patient prognosis. While the data generated from this study may not exhibit statistical significance, its clinical relevance is noteworthy. In summary, retesting of breast biomarkers in the resection specimen is recommended to accurately ascertain the appropriate use of targeted therapy.
Application of Compressible Carbon in Cement to Mitigate Cement Pore Pressure Reduction and Improve Cement Bonding

Summary
A quality cement job is essential to ensure long-term zonal isolation in oil/gas and carbon storage wells. This may be affected by the cement hydration process, during which water is consumed, causing pore pressure reduction and shrinkage, which increases the risk of fluid/gas invasion, formation of microannuli, and even the risk of shear bond strength reduction. In this paper, we present the application of compressible carbon (CC) particles as a cement additive to mitigate cement pore pressure reduction and improve zonal isolation. We designed cement formulations with CC and evaluated them using API standard tests and industry-wide recognized tests to ensure they met functional requirements for well cementing, such as mixability, thickening time, rheology, compressive strength development, fluid loss, and free water. The concept is as follows: When cement is pumped into an annulus, the CC particles will compress under hydrostatic pressure. When the cement is hydrating, the CC will expand to mitigate the pore pressure reduction. To validate the proof of concept, we developed a benchtop high-pressure, high-temperature setup and a pilot-scale test setup. A cement formulation with 9% CC by volume was found to be stable and have controllable performance properties such as thickening time, fluid loss, and free water. We also designed and tested a control slurry without CC for comparison. Both the benchtop and pilot-scale tests demonstrated that adding CC into the cement formulation mitigated the pore pressure reduction during cement hydration. This may reduce the risk of fluid/gas invasion that could result in migration in the set cement. Comparing the cement containing carbon with the control system without carbon, the gas permeability was reduced. The bond strength obtained from shear bond tests improved significantly, which may reduce the risk of debonding and be an indication of the reduction of shrinkage. In addition, a better hydraulic seal was found in one test, but further investigation is needed. Similar mechanical properties such as compressive strength were measured for both cements with and without CC. The data showed that adding CC does not have a negative impact on the hardened cement properties. In fact, adding CC decreased Poisson’s ratio slightly. In this paper, we present the results of proof-of-concept testing for the novel application of CC in cement to improve zonal isolation by mitigating pore pressure reduction. We also present new benchtop and pilot-scale experimental setups to measure pore pressure changes during cement hydration.
High-Temperature, Salt-Resistant, and High-Strength-Controlled Consolidated Resin Slurry for Fracture Plugging during Oil and Gas Well Drilling
Authors: Yang Jingbin , Bai Yingrui , Sun Jinsheng , Lv Kaihe 
Published: June 2024

Summary
The temperature and pressure of deep and ultradeep plugging are gradually increasing, resulting in higher requirements for the performance of plugging materials. In this study, a resin slurry plugging system that can be used to plug lost channels of fractures of different scales in the process of oil and gas exploitation was prepared, and the factors affecting the consolidation of the system under different conditions were studied. The resin slurry plugging system was initially consolidated in 2 hours and completely consolidated in 6–9 hours. It exhibited good viscosity recovery ability and excellent thixotropy characteristics of shear thinning and static thickening, which help realize strong residence and plugging in the fracture. The resin slurry plugging system prepared with 200 000 mg/L salinity water could still achieve good consolidation at 140°C, and the consolidating strength was higher than 5.0 MPa. In addition, the 7.10-MPa consolidation strength of the resin slurry plugging system with aging at 140°C for 15 days could satisfy the long-term plugging needs. Furthermore, the pressure-bearing plugging capacity and degradability of the resin slurry plugging system were investigated. The resin slurry plugging system could be fully filled in the steel wedge-shaped fractured core at 140°C, and the pressure-bearing plugging capacity was up to 13.07 MPa. The resin slurry plugging system could achieve a strong residence in the sand-filling pipe model, forming a high-strength plugging layer, and the pressure-bearing plugging capacity could reach 10.73 MPa. The acid dissolution degradation rate at 140°C was 97.69%, indicating a low degree of damage to the reservoir and meeting the requirements for subsequent plug removal. The excellent properties of the resin slurry plugging system, such as high temperature, high salt resistance, and pressure plugging, provide a new solution for plugging lost formations of fracture cave carbonate rocks.
Rosmanol Triggers Apoptosis Against MNNG-induced Gastric
Carcinogenesis in Rats through Attenuation of the P13K/AKT/HMBG1
Signaling Pathway
Authors: Niu Yan-Bang , Velu Periyannan , Khalid Awais , Zyoud Samer H. , Kazi Mohsin , Li Yuzhu 
Published: June 2024

Background:
Gastric cancer (GC) is a frequent malignant neoplasm found in China.
Despite numerous therapeutic methodologies to ameliorate the well-being of GC patients, their
efficiency remains inadequate.

Objective:
Rosmanol (RML) is a phenolic diterpene compound with antioxidant and anticancer
activities. In the current research, the apoptotic efficacy of RML on methylnitronitrosoguanidine
(MNNG)-induced GC model was determined.

Materials and Methods:
The rats were allocated into four sets, viz., normal control, MNNG
(200 mg/kg bw) + NaCl, MNNG + RML (20 mg/kg), and RML (20 mg/kg) orally treated for 20
weeks.

Results:
The results exposed that GC rats revealed higher (P<0.05) levels of TBARS and reduced antioxidant status in the stomach and liver tissues counter to other groups. In contrast, the
TBARS level was substantially alleviated (P<0.05) and restored the antioxidant status in RMLadministered rats. Histopathologic assessment of gastric tissue unveiled that an MNNG-induced
group presented squamous cell carcinoma with keratin pearls. The administration of RML reduced GC incidence, and only mild dysplasia was observed. Further, RML alleviated Bcl-2,
P13K, AKT, and HMGB1, as evidenced by RT-PCR and Western blot analysis.

Conclusion:
Furthermore, RML triggered caspase-mediated mitochondrial apoptosis through
the inactivation of the PI3K/AKT/HMGB1 pathway, eventually leading to GC cell death. This
highlights that RML may be a potential natural antioxidant employed as a chemoprotective
agent in GC rats.

Published: June 2024

Purpose:
Reproducibility and scale-up production of microspheres through spray drying
present significant challenges. In this study, biodegradable microspheres of Triamcinolone
Acetonide Acetate (TAA) were prepared using a novel static mixing method by employing poly(
lactic-co-glycolic acid) (PLGA) as the sustained-release carrier.

Methods:
TAA-loaded microspheres (TAA-MSs) were prepared using a static mixing technique.
The PLGA concentration, polyvinyl alcohol concentration (PVA), phase ratio of oil/water, and
phase ratio of water/solidification were optimized in terms of the particle size, drug loading (DL),
and encapsulation efficiency (EE) of TAA-MSs. The morphology of TAA-MSs was examined using
Scanning Electron Microscopy (SEM), while the physicochemical properties were evaluated
through X-ray diffraction (XRD), Differential Scanning Calorimetry (DSC), and Fourier Transform
Infrared Spectroscopy (FT-IR). The in vitro release of TAA-MSs was compared to that of
the pure drug (TAA) using a water-bath vibration method in the medium of pH 7.4 at 37°C.

Results:
The formulation composition and preparation condition for the preparation of TAA-MSs
were optimized as follows: the PLGA concentration was 1%, the phase ratio of
oil(dichloromethane) /water (PVA solution) was 1:3, the phase ratio of water (PVA solution)/solidification
was 1:2. The optimized TAA-MSs displayed spherical particles with a size range of
30-70 μm, and DL and EE values of 27.09% and 98.67%, respectively. Moreover, the drug-loaded
microspheres exhibited a significant, sustained release, with 20% of the drug released over a period
of 28 days. The XRD result indicated that the crystalline form of TAA in microspheres had
been partly converted into the amorphous form. DSC and FT-IR results revealed that some interactions
between TAA and PLGA occurred, indicating that the drug was effectively encapsulated into
PLGA microspheres.

Conclusion:
TAA-loaded PLGA microspheres have been successfully prepared via the static mixing
technique with enhanced EE and sustained-release manner.
