Authors: Noah Ghadeer 
Published: December 2024

Background: Lupus nephritis (LN) is a serious complication of systemic lupus erythematosus (SLE) and evident in 60% of patients. Complement system and its product, complement component 4 degradation (C4d), plays an important role in the pathogenesis of LN. The aim is to determine the prognostic value of C4d detection in different classes of LN and correlation with laboratory results and histopathologic activity score.
Methods: Thirty-five patients with LN were collected between January to September 2023. Blood levels of anti-nuclear antigens (ANA), anti-double stranded DNA antibody (Anti-dsDNA), C3, C4, and 24hr urine protein were measured. Renal tissue biopsy was examined regarding glomerular C4d antibody immunohistochemical staining and Classes of LN according to International society of nephrology/Renal Pathology Society (ISN/RPS).
Results: Glomerular C4d was expressed in 40% of LN patients and was significantly correlated with urinary protein excretion (p=0.001) and Anti-dsDNA antibody (P=0.048), but not with LN classes or activity score or low complements.
Conclusions: Glomerular C4d deposition of LN does not indicate the present disease activity but may help to identify a subset of patients with worse renal prognosis, providing insights about the therapeutic approaches for SLE with LN.
Keywords: Lupus nephriti, glomerular C4d, proteinuria, Anti-double stranded DNA Antibody.

Published: December 2024

Abstract
Background: The term triple-negative breast cancer (TNBC) refers to a particular class of aggressive, poorly differentiated neoplasms that show the absence of estrogen (ER), progesterone (PR), and human epidermal growth factor receptor2 (HER2) antibodies. The aim of this study is to assess the immunohistochemical expression of SOX10 in TNBC, its correlation with tumor grade and other clinicopathologic characteristics.
Materials and methods: A Cross sectional study which included thirty paraffin blocks of primary (TNBC) , that were collected from Karbala teaching centre of histopathology in the period (from Jan. 2023 to Dec. 2023). For each of the collected block, two sections were taken. One stained by hematoxylin and eosin and the other was stained by immunohistochemical method for SOX10.
Results: SOX10 reported positive in 43% (13) positive cases versus 57% (17) negative cases, this positivity was significantly correlated with pathological grade (p value =0.012) and the pathological stage (p value =0.038). A particular statistical significance was found in association with the lymph node group and distant metastasis. (p value 0.039 and 0.037) respectively. No significant statistical difference between SOX10 expression and the patient’s age, tumor size, presence of Ductal carcinoma in situ (DCIS) and lymphovascular invasion.
Conclusion:
The study suggested that SOX10 expression is a prognostic biomarker for TNBC. It also highlighted the clinical significance of targeting SOX10 as a promising potential therapeutic target gene for TNBC therapy.

Keywords: SOX10; triple negative breast cancer; immunohistochemistry.
Artificial intelligence role in improving vitro fertilization and embryology
Authors: Hafedh Sahbaa , Flayyih Hasan Noor 
Published: December 2024

Abstract:
For the past decade, the success rate of IVF has been constant. Many studies aim to enhance the existing success rate of IVF, which is around 30%. Artificial intelligence (AI) has the liability to improve medical results. Embryo evaluation and choice represent the total manifestation of the in vitro fertilization (IVF) procedure. The goal is to choose the "best" embryos from a wide pool of fertilized oocytes, as many may not be viable owing to aberrant development or chromosomal abnormalities. This essay explores whether AI has the ability to improve fertility results in IVF.

Abstract

Background
Prolonged exposure to hand-arm vibration is associated with a disorder of the vascular, neurological, and musculoskeletal systems of the upper limb known as hand-arm vibration syndrome (HAVS). Currently, the evidence of HAVS in tropical environments is limited.

Objectives
To determine the prevalence and severity of HAVS among tyre shop workers in Kelantan, Malaysia.

Methods
A cross-sectional study involving 200 tyre shop workers from two districts in Kelantan was performed. Part one data were collected at the field using questionnaire, and hand-arm vibration was measured. Part two involved a set of hand clinical examinations. The workers were divided into high (≥5 m s−2) and low/moderate (&lt;5 m s-2) exposure group according to their 8-hr time weighted average [A(8)] of vibration exposure. The differences between the two exposure group were then compared.

Results
The prevalence of the vascular, neurological, and musculoskeletal symptoms was 12.5% (95% CI 10.16 to 14.84), 37.0% (95% CI 30.31 to 43.69), and 44.5% (95% CI 37.61 to 51.38) respectively. When divided according to their exposure statuses, there was a significant difference in the prevalence of HAVS for all three components of vascular, neurological, and musculoskeletal (22.68% vs 2.91%, 62.89% vs 12.62% and 50.52% and 38.83%) respectively. All the clinical examinations findings also significantly differed between the two groups with the high exposure group having a higher abnormal result.

Conclusion
Exposure to high A(8) of vibration exposure was associated with a higher prevalence of all three component of HAVS. There is a need for better control of vibration exposure in Malaysia.

AbstractThe further development of “lab on fiber” technology demands more powerful optical microsystems and optical fibers with special functions to create sensors with better performance. Whispering gallery microcavities (WGMs) made of different materials with high quality factors show very good sensitivity to gases, nanoparticles, and biocomponents. However, realizing the excitation and detection of the resonant modes of WGMs on the facets of optical fibers is still a great challenge. This work employs the advanced 3D manufacturing technology of two‐photon lithography to fabricate an optical microsystem on the end facet of a multicore optical fiber, which enables excitation and detection of whispering gallery modes on the end facet of an optical fiber. Whispering gallery modes with high quality factors are observed, and the sensing characterization of this device for vapors of three types of volatile organic compounds is investigated. Such optical fiber vapor sensors can be applied in the fields of medical care, environmental monitoring and chemical manufacturing. Additionally, the out‐of‐plane light coupling strategy may be useful for the design of integrated optical circuits on chips.

Published: July 2019

AbstractSubstantial effort has been devoted to both scientific and technological developments of wearable, flexible, semitransparent, and sensing electronics (e.g., organic/perovskite photovoltaics, organic thin‐film transistors, and medical sensors) in the past decade. The key to realizing those functionalities is essentially the fabrication of conductive electrodes with desirable mechanical properties. Conductive polymers (CPs) of poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) have emerged to be the most promising flexible electrode materials over rigid metallic oxides and play a critical role in these unprecedented devices as transparent electrodes, hole transport layers, interconnectors, electroactive layers, or motion‐sensing conductors. Here, the current status of research on PEDOT:PSS is summarized including various approaches to boosting the electrical conductivity and mechanical compliance and stability, directly linked to the underlying mechanism of the performance enhancements. Along with the basic principles, the most cutting edge‐progresses in devices with PEDOT:PSS are highlighted. Meanwhile, the advantages and plausible problems of the CPs and as‐fabricated devices are pointed out. Finally, new perspectives are given for CP modifications and device fabrications. This work stresses the importance of developing CP films and reveals their critical role in the evolution of these next‐generation devices featuring wearable, deformable, printable, ultrathin, and see‐through characteristics.

Published: July 2019

AbstractSubmucosal elevation, the process of instilling material in the submucosal space for separation of the surface mucosa and deeper muscularis layer, is a significant aspect of the endoscopic mucosal resection of large lesions performed to facilitate lesion removal and maximize safety. Submucosal injection, when applied, has historically been performed with normal saline, though this is limited by its rapid dissipation; solutions ideally need to be easily injectable, biocompatible, and provide a long‐lasting submucosal cushion with a desirable height. Here, reported is a new set of materials, endoscopically injectable shear‐thinning hydrogels, meeting these requirements because of their biocompatible components and ability to form a solid hydrogel upon injection. These findings are supported by evaluation in a large animal model and ultimately demonstrate the potential of these shear‐thinning hydrogels to serve as efficient submucosal injection fluids for cushion development. Given these unique characteristics, their broad application in mucosal resection techniques is anticipated.

AbstractA dense hydrogen‐bond network is responsible for the mechanical and structural properties of polysaccharides. Random derivatization alters the properties of the bulk material by disrupting the hydrogen bonds, but obstructs detailed structure–function correlations. We have prepared well‐defined unnatural oligosaccharides including methylated, deoxygenated, deoxyfluorinated, as well as carboxymethylated cellulose and chitin analogues with full control over the degree and pattern of substitution. Molecular dynamics simulations and crystallographic analysis show how distinct hydrogen‐bond modifications drastically affect the solubility, aggregation behavior, and crystallinity of carbohydrate materials. This systematic approach to establishing detailed structure–property correlations will guide the synthesis of novel, tailor‐made carbohydrate materials.

Published: July 2019

AbstractDie elektronenpräzisen binären Borsubhalogenide [B2X6]2− (X=F, Br, I) wurden synthetisiert und strukturell im Festkörper untersucht. Zudem konnte die vermutete Existenz von [B2Cl6]2− mittels Röntgendiffraktometrie nachgewiesen werden. Diese Dianionen sind isoelektronisch zu den Hexahalogeniden des Ethans und können als Homologe des Tetrahalogenborat‐Anions BX4− betrachtet werden. Darüber hinaus gehören sie zu den seltenen Beispielen von elektronenpräzisen binären Borverbindungen (B2X4, BX3, [BX4]−).

Published: July 2019

AbstractStructure and defect control are widely accepted effective strategies to manipulate the activity and stability of catalysts. On a freestanding hierarchically porous carbon microstructure, the tuning of oxygen vacancy in the embedded hollow cobaltosic oxide (Co3O4) nanoparticles is demonstrated through the regulation of nanoscale Kirkendall effect. Starting with the embedded cobalt nanoparticles, the concentration of oxygen‐vacancy defect can vary with the degree of Kirkendall oxidation, thus regulating the number of active sites and the catalytic performances. The optimized freestanding catalyst shows among the smallest reversible oxygen overpotential of 0.74 V for catalyzing oxygen reduction/evolution reactions in 0.1 m KOH. Moreover, the catalyst shows promise for substitution of noble metals to boost cathodic oxygen reactions in portable zinc–air batteries. This work provides a strategy to explore catalysts with controllable vacancy defects and desired nano‐/microstructures.
Targeted Synthesis of a Zeolite with Pre‐established Framework Topology
Authors: Jo Donghui , Hong Suk Bong 
Published: July 2019

AbstractGiven their great potential as new industrial catalysts and adsorbents, the search for new zeolite structures is of major importance in nanoporous materials chemistry. However, although innumerable theoretical frameworks have been proposed, none of them have been synthesized by a priori design yet. We generated a library of diazolium‐based cations inspired from the organic structure‐directing agents (OSDAs) recently reported to give two structurally related zeolites (PST‐21 and PST‐22) under highly concentrated, excess‐fluoride conditions and compared the stabilization energies of each OSDA cation in ten pre‐established hypothetical structures. A combination of the ability of the OSDA selected in this way with the excess‐fluoride approach has allowed us to crystallize PST‐30, the targeted aluminosilicate zeolite structure. We anticipate that our approach, which aims to rationally couple computational predictions of OSDAs with an experimental setup, will advance further development in the synthesis of zeolites with desired properties.

AbstractA BN membrane with a distinct nanoconfinement effect toward efficient ethylene/ethane separation is presented. The horizontal and inclined self‐assembly of 2D BN nanosheets endow the BN membrane with abundant percolating nanochannels, and these nanochannels are further decorated by reactive ionic liquids (RILs) to tailor their sizes as well as to achieve nanoconfinement effect. The noncovalent interactions between RIL and BN nanosheets favor the ordered alignment of the cations and anions of RIL within BN nanochannels, which contributes to a fast and selective ethylene transport. The resultant membranes exhibit an unprecedented separation performance with superhigh C2H4 permeance of 138 GPU and C2H4/C2H6 selectivity of 128 as well as remarkably improved long‐term stability for 180 h, outperforming reported state‐of‐the‐art membranes.

AbstractAqueous Na‐ or K‐ion batteries could virtually eliminate the safety and cost concerns raised from Li‐ion batteries, but their widespread applications have generally suffered from narrow electrochemical potential window (ca. 1.23 V) of aqueous electrolytes that leads to low energy density. Herein, by exploring optimized eutectic systems of Na and K salts with asymmetric imide anions, we discovered, for the first time, room‐temperature hydrate melts for Na and K systems, which are the second and third alkali metal hydrate melts reported since the first discovery of Li hydrate melt by our group in 2016. The newly discovered Na‐ and K‐ hydrate melts could significantly extend the potential window up to 2.7 and 2.5 V (at Pt electrode), respectively, owing to the merit that almost all water molecules participate in the Na+ or K+ hydration shells. As a proof‐of‐concept, a prototype Na3V2(PO4)2F3|NaTi2(PO4)3 aqueous Na‐ion full‐cell with the Na‐hydrate‐melt electrolyte delivers an average discharge voltage of 1.75 V, that is among the highest value ever reported for all aqueous Na‐ion batteries.
