Fulltext Cellular Uptake and Bioavailability of Tocotrienol-Rich Fraction in SIRT1-Inhibited Human Diploid Fibroblasts

Jaafar F, Abdullah A, Makpol S

Sci Rep, 2018 Jul 11;8(1):10471.
PMID: 29992988 DOI: 10.1038/s41598-018-28708-z

Tocotrienol-rich fraction (TRF) is palm vitamin E that consists of tocopherol and tocotrienol. TRF is involved in important cellular regulation including delaying cellular senescence. A key regulator of cellular senescence, Sirtuin 1 (SIRT1) is involved in lipid metabolism. Thus, SIRT1 may regulate vitamin E transportation and bioavailability at cellular level. This study aimed to determine the role of SIRT1 on cellular uptake and bioavailability of TRF in human diploid fibroblasts (HDFs). SIRT1 gene in young HDFs was silenced by small interference RNA (siRNA) while SIRT1 activity was inhibited by sirtinol. TRF treatment was given for 24 h before or after SIRT1 inhibition. Cellular concentration of TRF isomers was determined according to the time points of before and after TRF treatment at 0, 24, 48, 72 and 96 h. Our results showed that all tocotrienol isomers were significantly taken up by HDFs after 24 h of TRF treatment and decreased 24 h after TRF treatment was terminated but remained in the cell up to 72 h. The uptake of α-tocopherol, α-tocotrienol and β-tocotrienol was significantly higher in senescent cells as compared to young HDFs indicating higher requirement for vitamin E in senescent cells. Inhibition of SIRT1 gene increased the uptake of all tocotrienol isomers but not α-tocopherol. However, SIRT1 inhibition at protein level decreased tocotrienol concentration. In conclusion, SIRT1 may regulate the cellular uptake and bioavailability of tocotrienol isomers in human diploid fibroblast cells while a similar regulation was not shown for α-tocopherol.

Catalysts prepared from industrial wastes rich in Fe, Ca, Si, and Al were used in catalytic upgrading of pyrolysis vapour derived from durian shell and their effect on product yield and properties were compared. With same silica-to-alumina ratio, catalyst prepared from oil palm ash (AS-OPA) with lower Fe and Ca contents gave higher liquid yield (8.32 wt%) with alcohols (28.90%), hydrocarbons (46.00%), and nitrogen-containing compounds (21.46%) while catalyst prepared from electric arc furnace slag (AS-EAF) with higher Fe and Ca contents produced lower liquid yield (50.21 wt%) with high amount of esters (25.80%) and hydrocarbons (72.82%). The presence of AS-OPA and AS-EAF catalysts enhanced deoxygenation degree of bio-oil to 81.13% and 85.49%, respectively. The catalytic performance of AS-EAF at different temperatures (400-600 °C) and AS-EAF/durian shell ratios (1:30, 2:30, 3:30) was investigated. Increasing catalytic temperature enhanced production of bio-oil, reduced oxygenates and enhanced formation of esters. The liquid yield and yield of esters decreased with increasing catalyst loading. Hydrocarbons (mainly neopentane) were the major chemical compounds found in bio-oil produced over AS-EAF. Besides that, AS-EAF showed good deoxygenation performance with highest selectivity of hydrocarbons at 500 °C and AS-EAF/durian shell ratio of 2:30. Catalytic fast pyrolysis of durian shell using waste-derived catalysts is an effective waste management strategy as the bio-oil produced can be a potential alternative source of energy or chemical feedstocks.

Breast cancer is one of the most common malignancies among woman. Decades of scientific study have linked the
overexpression of ERBB2 antigen to aggressive tumors. To target aggressive breast cancer, chimeric antigen receptor
(CAR) technology can be utilized. For this, human T-cells are transduced with a gene sequence encoding a CAR that is
specific for tumor-associated antigens (TAAs). These genetically-engineered CAR transduced T-cells (CAR-T cells) are
able to target the tumor antigen without the need for major histocompatibility complex (MHC) recognition, rendering
it a potentially universal immunotherapeutic option. However, efficient transduction of therapeutic gene into human
T-cells and further cell expansion are challenging. In this study, we reported a successful optimization of a transduction
protocol using spinoculation on CD3+ T-cells with different concentrations of lentiviral plasmid encoding the CAR gene.
CD3+T-cells were isolated from the peripheral blood mononuclear cells (PBMCs). The constructed CAR gene was inserted
into a lentiviral plasmid containing the green fluorescent protein (GFP) tag and lentiviral particles were produced. These
lentiviral particles were used to transduce activated T-cells by spinoculation. T-cells were activated using Dynabeadconjugated
CD3/CD28 human T-cell activator and interleukin-2 (IL-2) before transduction. CD3+ T-cells were selected
and GFP expression, which indicated transduction, was observed. Future studies will focus on in vitro and in vivo models
to determine the efficiency of CAR-T cells in specifically targeting ERBB2-expressing cells.
Experimental Brachiaria decumbens toxicity in cattle

Noordin MM, Salam Abdullah A, Rajion MA

Vet Res Commun, 1989;13(6):491-4.
PMID: 2631385

Although Brachiaria decumbens was not toxic when fed to cattle, the infusion of rumen liquor from B. decumbens intoxicated sheep into the rumen of cattle produced evidence suggesting hepatic and renal dysfunction. Several biochemical changes were observed including increases in serum aspartate amino transferase, serum creatinine and blood urea nitrogen and a marked reduction in the plasma bromosulphthalein clearance.

Tan YL, Abdullah AZ, Hameed BH

Bioresour Technol, 2017 Nov;243:85-92.
PMID: 28651142 DOI: 10.1016/j.biortech.2017.06.015

Durian shell (DS) was pyrolyzed in a drop-type fixed-bed reactor to study the physicochemical properties of the products. The experiment was carried out with different particle sizes (up to 5mm) and reaction temperatures (250-650°C). The highest bio-oil yield was obtained at 650°C (57.45wt%) with DS size of 1-2mm. The elemental composition and higher heating value of the feedstock, bio-oil (650°C), and bio-char (650°C) were determined and compared. The compositions of product gases were determined via gas chromatography with thermal conductivity detector. The chemical composition of bio-oil was analyzed by gas chromatography-mass spectrometry. The bio-oil produced at lower temperature yields more alcohols, whereas the bio-oil produced at higher temperature contains more aromatics and carbonyls. Bio-oil has potential to be used as liquid fuel or fine chemical precursor after further upgrading. The results further showed the potential of bio-char as a solid fuel.
The dynamic relationship between structural change and CO2 emissions in Malaysia: a cointegrating approach

Ali W, Abdullah A, Azam M

Environ Sci Pollut Res Int, 2017 May;24(14):12723-12739.
PMID: 28378312 DOI: 10.1007/s11356-017-8888-6

The current study investigates the dynamic relationship between structural changes, real GDP per capita, energy consumption, trade openness, population density, and carbon dioxide (CO2) emissions within the EKC framework over a period 1971-2013. The study used the autoregressive distributed lagged (ARDL) approach to investigate the long-run relationship between the selected variables. The study also employed the dynamic ordinary least squared (DOLS) technique to obtain the robust long-run estimates. Moreover, the causal relationship between the variables is explored using the VECM Granger causality test. Empirical results reveal a negative relationship between structural change and CO2 emissions in the long run. The results indicate a positive relationship between energy consumption, trade openness, and CO2 emissions. The study applied the turning point formula of Itkonen (2012) rather than the conventional formula of the turning point. The empirical estimates of the study do not support the presence of the EKC relationship between income and CO2 emissions. The Granger causality test indicates the presence of long-run bidirectional causality between energy consumption, structural change, and CO2 emissions in the long run. Economic growth, openness to trade, and population density unidirectionally cause CO2 emissions. These results suggest that the government should focus more on information-based services rather than energy-intensive manufacturing activities. The feedback relationship between energy consumption and CO2 emissions suggests that there is an ominous need to refurbish the energy-related policy reforms to ensure the installations of some energy-efficient modern technologies.

PMID: 37077659 DOI: 10.1155/2023/9291417

Certain dietary chemicals influenced the expression of chemopreventive genes through the Nrf2-Keap1 pathway. However, the difference in Nrf2 activation potency of these chemicals is not well studied. This study is aimed at determining the difference in the potency of liver Nrf2 nuclear translocation induced by the administration of equal doses of selected dietary chemicals in mice. Male ICR white mice were administered 50 mg/kg of sulforaphane, quercetin, curcumin, butylated hydroxyanisole, and indole-3-carbinol for 14 days. On day 15, the animals were sacrificed, and their livers were isolated. Liver nuclear extracts were prepared, and Nrf2 nuclear translocation was detected through Western blotting. To determine the implication of the Nrf2 nuclear translocation on the expression levels of several Nrf2-regulated genes, liver RNA was extracted for qPCR assay. Equal doses of sulforaphane, quercetin, curcumin, butylated hydroxyanisole, and indole-3-carbinol significantly induced the nuclear translocation of Nrf2 with different intensities and subsequently increased the expression of Nrf2-regulated genes with an almost similar pattern as the Nrf2 nuclear translocation intensities (sulforaphane > butylated hydroxyanisole = indole-3-carbinol > curcumin > quercetin). In conclusion, sulforaphane is the most potent dietary chemical that induces the Nrf2 translocation into the nuclear fraction in the mouse liver.
Fulltext A Rare Case of Idiopathic Bilateral Medial Canal Fibrosis

Kamaruzaman F, Ibrahim MIS, Abdullah A

Cureus, 2023 Jul;15(7):e41830.
PMID: 37575837 DOI: 10.7759/cureus.41830

Medial canal fibrosis usually occurs as sequelae of known conditions such as trauma, infection, or surgery. Rarely, it occurs without an identifiable cause, hence the term idiopathic medial canal fibrosis. Regardless of the etiology, the reportedly most successful treatment is surgery. A 52-year-old lady presented to us with bilateral reduced hearing and left ear tinnitus. There was no significant history to suggest the possible cause of the symptoms. Clinically, there is the presence of thick solid fibrous in the bilateral ear canal. Audiological examination revealed a conductive hearing loss bilaterally with tympanometry of type B, and imaging was done. She successfully underwent canalplasty following that and is doing well to date. In this paper, we reported a rare case of bilateral idiopathic medical canal fibrosis, and we discuss the causes, diagnosis, and best treatment for this disease.

Fulltext Finding the Silver Bullet for Persistent Foramen Hushke

Teoh T, Abdullah A, Kumarasamy G

Cureus, 2024 Jan;16(1):e52791.
PMID: 38389601 DOI: 10.7759/cureus.52791

We report a case of persistent foramen Hushke and embark on a literature search from 1990 to 2021. The search was done using electronic databases of PubMed and Google Scholar using the MESH words 'TMJ herniation', 'persistent foramen Hushke', 'TMJ prolapse', 'EAC dehiscence', and 'ear canal mass'. A total of 37 other case reports were included after excluding duplicates and non-English publications. The most common presentations, treatment modalities, complications, and outcomes were discussed. Common presentations include otalgia, tinnitus, otorrhea, and aural fullness. Surgical intervention shows a good outcome, whereas conservative treatment shows a mixed response. Despite the overwhelming success of surgical interventions in treating symptomatic persistent foramen of Hushke, it is still early to establish a guideline to manage these patients, as this condition is rare and presents with variable symptoms. More high-quality studies and a long-term follow-up of the patients may be essential to observe and compare the outcome and recurrence rate of temporomandibular joint (TMJ) herniation.

Tuang GJ, Mansor M, Abdullah A

Indian J Otolaryngol Head Neck Surg, 2022 Dec;74(Suppl 3):3671-3674.
PMID: 36742599 DOI: 10.1007/s12070-020-02316-8

Microtia comprises a spectrum of congenital malformation characterized by partial deformities of the auricular components to complete absence of pinna. Surgical reconstructions of this anomaly are often complex and technically challenging. Infection, hematoma, and skin necrosis with resultant exposed cartilage graft tend to occur in the early phase of post-operative care. Herein, we report a case of a spontaneous auricular abscess with exposed cartilage framework 20 years following rib cartilage reconstruction. To our knowledge, this is the first case of such an occurrence. The treatment options are discussed, along with the review of the literature.

Diabetes Metab Syndr, 2013;7(4):191-7.
PMID: 24290082 DOI: 10.1016/j.dsx.2013.10.023

AIMS: The aim of this study was to investigate the association between pregnancy complications, mental health-related problems, and type 2 diabetes mellitus (T2DM) in Malaysian women.
MATERIALS AND METHODS: A case-control study of women with T2DM (n=160) matched by age range to controls without T2DM (n=160). Data were collected in the Negeri Sembilan and PutraJaya regions in Malaysia, from two hospital outpatient clinics, PutraJaya Hospital and Tuanku Jaa'far Hospital Seremban, and one health clinic at Seremban. Validated, interviewer-administered questionnaires were used to obtain the data. The unadjusted and adjusted estimates were calculated using the Mantel-Haenszel method.
RESULTS: Neither depression (RR 0.74, 95% CI: 0.39-1.41) nor anxiety (RR 1.00, 95% CI: 0.53-1.88) symptoms increased the risk of T2DM significantly. However, gestational diabetes (RR 1.35, 95% CI: 1.02-1.79), and ≥3 pregnancies (RR 1.39, 95% CI: 1.08-1.79) were significant risk factors for the development of T2DM. T2DM was not a significant risk factor for either depression (RR 1.26, 95% CI: 0.91-1.74) or anxiety symptoms (RR 1.13, 95% CI: 0.59-2.19).
CONCLUSION: In this study, T2DM is not a significant risk factor for depression and anxiety; similarly, neither are depression and anxiety significant risk factors for T2DM. Although prevalence of depression and anxiety is not alarming, the findings reported here should alert clinicians to screen and treat anxiety and depression in people with diabetes and also note the importance of monitoring women with complications in pregnancy for risk of later T2DM.

The influence of artery wall curvature on the anatomical assessment of stenosis severity derived from fractional flow reserve: a computational fluid dynamics study

Govindaraju K, Viswanathan GN, Badruddin IA, Kamangar S, Salman Ahmed NJ, Al-Rashed AA

Comput Methods Biomech Biomed Engin, 2016 Nov;19(14):1541-9.
PMID: 27052093 DOI: 10.1080/10255842.2016.1170119

This study aims to investigate the influence of artery wall curvature on the anatomical assessment of stenosis severity and to identify a region of misinterpretation in the assessment of per cent area stenosis (AS) for functionally significant stenosis using fractional flow reserve (FFR) as standard. Five artery models of different per cent AS severity (70, 75, 80, 85 and 90%) were considered. For each per cent AS severity, the angle of curvature of the arterial wall varied from straight to an increasingly curved model (0°, 30°, 60°, 90° and 120°). Computational fluid dynamics was performed under transient physiologic hyperemic flow conditions to investigate the influence of artery wall curvature on the pressure drop and the FFR. The findings in this study may be useful in in vitro anatomical assessment of functionally significant stenosis. The FFR decreased with increasing stenosis severity for a given curvature of the artery wall. Moreover, a significant decrease in FFR was found between straight and curved models discussed for a given severity condition. These findings indicate that the curvature effect was included in the FFR assessment in contrast to minimum lumen area (MLA) or per cent AS assessment. The MLA or per cent AS assessment may lead to underestimation of stenosis severity. From this numerical study, an uncertainty region could be evaluated using the clinical FFR cutoff value of 0.8. This value was observed at 81.98 and 79.10% AS for arteries with curvature angles of 0° and 120° respectively. In conclusion, the curvature of the artery should not be neglected in in vitro anatomical assessment.

Natural polymer guar gum has one of the highest viscosities in water solution and hence, these are significantly used in pharmaceutical applications. Guar gum inter-connected micelles as a new carrier has been developed for poor water soluble rifampicin drug. The hydrogel inter-connected micelle core was formulated as a hydrophilic inner and hydrophobic outer core by using guar gum/chitosan/polycaprolactone and the carrier interaction with rifampicin was confirmed by FT-IR. The morphological observations were carried out through TEM, SEM and AFM analysis. The encapsulation efficiency and in-vitro drug release behavior of prepared hydrogel based micelle system was analyzed by UV-vis spectrometry. The anti-bacterial activity against K. pneumoniae and S. aureus was studied by observing their ruptured surface by SEM. The cytotoxicity study reveals that the pure polymeric system has no toxic effect whereas drug loaded ones showed superior activity against THP-1 cells. From the cell apoptosis analyses, the apoptosis was carried out in a time dependent manner. The cell uptake behavior was also observed in THP-1 cells which indicate that the hydrogel based micelle system is an excellent material for the mucoadhesive on intracellular alveolar macrophage treatment.

BACKGROUND: Mycoplasma pneumoniae (MP) is a common cause of community-acquired pneumonia (CAP) among the children and adults that results upper and lower respiratory tract infections.
OBJECTIVE: This study was aimed to inspect the ameliorative action of A. chinensis synthesized ZnONPs against M. pneumoniae infected pneumonia mice model.
MATERIALS AND METHODS: ZnO NPs was synthesized from Albizia chinensis bark extract and characterized by UV-Vis spectroscopy, Fourier Transform Infrared (FTIR), Transmission Electron Microscopy (TEM), energy dispersive X-ray (EDX) and atomic force microscope (AFM) analyses. The antibacterial effectual of synthesized ZnONPs were examined against clinical pathogens. The pneumonia was induced to BALB/c mice via injecting the M. pneumoniae and treated with synthesized ZnONPs, followed by the total protein content, total cell counts and inflammatory mediators level was assessed in the BALF of experimental animals. The Histopathological investigation was done in the lung tissues of test animals.
RESULTS: The outcomes of this work revealed that the formulated ZnONPs was quasi-spherical, radial and cylindrical; the size was identified as 116.5 ± 27.45 nm in diameter. The in vitro antimicrobial potential of formulated ZnO-NPs displayed noticeable inhibitory capacity against the tested fungal and bacterial strains. The administration of synthesized ZnO-NPs in MP infected mice model has significantly reduced the levels of total protein, inflammatory cells, inflammatory cytokines such as IL-1, IL-6, IL-8, tumour necrosis factor-alpha (TNF-a) and transforming growth factor (TGF). Besides, the histopathological examination of MP infected mice lung tissue showed the cellular arrangements were effectively retained after administration of synthesized ZnO-NPs.
CONCLUSION: In conclusion, synthesized ZnO-NPs alleviate pneumonia progression via reducing the level of inflammatory cytokines and inflammatory cells in MP infected mice model.
Thermoresponsive surfaces designed for the proliferation and differentiation of human pluripotent stem cells

Higuchi A, Hirad AH, Kumar SS, Munusamy MA, Alarfaj AA

Acta Biomater, 2020 10 15;116:162-173.
PMID: 32911107 DOI: 10.1016/j.actbio.2020.09.010

Thermoresponsive surfaces enable the detachment of cells or cell sheets by decreasing the temperature of the surface when harvesting the cells. However, human pluripotent stem cells (hPSCs), such as embryonic stem cells and induced pluripotent stem cells, cannot be directly cultured on a thermoresponsive surface; hPSCs need a specific extracellular matrix to bind to the integrin receptors on their surfaces. We prepared a thermoresponsive surface by using poly(N-isopropylacrylamide-co-butylacrylate) and recombinant vitronectin to provide an optimal coating concentration for the hPSC culture. hPSCs can be cultured on the same thermoresponsive surface for 5 passages by partial detachment of the cells from the surface by decreasing the temperature for 30 min; then, the remaining hPSCs were subsequently cultured on the same dishes following the addition of new cultivation media. The detached cells, even after continual culture for five passages, showed high pluripotency, the ability to differentiate into cells derived from the 3 germ layers and the ability to undergo cardiac differentiation.

PMID: 27524047 DOI: 10.1016/j.msec.2016.06.028

Nanocomposites of zinc oxide loaded on a zeolite (Zeolite/ZnO NCs) were prepared using co-precipitation method. The ratio effect of ZnO wt.% to the Zeolite on the antibacterial activities was investigated. Various techniques were used for the nanocomposite characterization, including UV-vis, FTIR, XRD, EDX, FESEM and TEM. XRD patterns showed that ZnO peak intensity increased while the intensities of Zeolite peaks decreased. TEM images indicated a good distribution of ZnO-NPs onto the Zeolite framework and the cubic structure of the zeolite was maintained. The average particle size of ZnO-nanoparticles loaded on the surface of the Zeolite was in the range of 1-10nm. Moreover, Zeolite/ZnO NCs showed noticeable antibacterial activities against the tested bacteria; Gram- positive and Gram- negative bacteria, under normal light. The efficiency of the antibacterial increased with increasing the wt.% from 3 to 8 of ZnO NPs, and it reached 87% against Escherichia coli E266.
Anti-Inflammatory Potential of Ethyl Acetate Fraction of Moringa oleifera in Downregulating the NF-κB Signaling Pathway in Lipopolysaccharide-Stimulated Macrophages

Arulselvan P, Tan WS, Gothai S, Muniandy K, Fakurazi S, Esa NM, et al.

Molecules, 2016 Oct 31;21(11).
PMID: 27809259

In the present investigation, we prepared four different solvent fractions (chloroform, hexane, butanol, and ethyl acetate) of Moringa oleifera extract to evaluate its anti-inflammatory potential and cellular mechanism of action in lipopolysaccharide (LPS)-induced RAW264.7 cells. Cell cytotoxicity assay suggested that the solvent fractions were not cytotoxic to macrophages at concentrations up to 200 µg/mL. The ethyl acetate fraction suppressed LPS-induced production of nitric oxide and proinflammatory cytokines in macrophages in a concentration-dependent manner and was more effective than the other fractions. Immunoblot observations revealed that the ethyl acetate fraction effectively inhibited the expression of inflammatory mediators including cyclooxygenase-2, inducible nitric oxide synthase, and nuclear factor (NF)-κB p65 through suppression of the NF-κB signaling pathway. Furthermore, it upregulated the expression of the inhibitor of κB (IκBα) and blocked the nuclear translocation of NF-κB. These findings indicated that the ethyl acetate fraction of M. oleifera exhibited potent anti-inflammatory activity in LPS-stimulated macrophages via suppression of the NF-κB signaling pathway.

Anxiety and depression are more common among females and those experiencing diabetes and menopause. Menopausal symptoms experienced by women can vary tremendously from population to population; therefore, there is a need to investigate these symptoms and associated risk factors in different communities. This study investigated the differences in psychological health and menopause-specific quality of life (MENQOL) between women with and without diabetes type 2 (T2DM) in Malaysia. Women with T2DM (n=320) were matched by age range to controls without T2DM (n=320). Data were collected from March 2012 to January 2013. Delusions Symptoms States Inventory (DSSI) instrument was used to identify symptoms of depression and anxiety. Women with diabetes had higher depressive (11.8% versus 8.4%) and anxiety (8.4% versus 6.6%) symptoms compared to women without diabetes. In both groups, the most common menopausal symptom was aches (muscles and joints). Women without diabetes had significantly higher scores for the sexual domain compared to women with diabetes (4.20 versus 3.21, p=0.001). The odds that a postmenopausal woman with diabetes was depressed or anxious on the DSSI scale increased significantly when the MENQOL score on the physical, vasomotor, and psychosocial domains increased by one unit. Both diabetes and psychological problems have negative impact on MENQOL. Our findings support the view of screening postmenopausal women with diabetes for depressive and anxiety, to improve overall quality of life.
