Negative bias temperature instability (NBTI) is a common phenomenon in a p-channel MOSFET device
under a negative gate-to-source voltage at a high stress temperature. This paper presents the NBTI
characterisation based on different analysis methods and stress conditions on p-MOSFET devices. The
atomic hydrogen concentration is probed at interface, Poly-Si and channel of p-MOSFET under study
using SILVACO TCAD tool. In addition, the behaviour of the permanent and recoverable component
was investigated based on AC stress at different stress conditions using Modelling Interface Generation
(MIG) tool. The results show that increases in temperature, negative voltage stress gate and decreases
in frequency increase the threshold voltage shift, thus enhancing NBTI degradation.

Negative bias temperature instability (NBTI) is the most concern issue CMOS devices with the scaling
down of the CMOS technologies. NBTI effect contributes to P-MOSFET device degradation which later
reduce the performance and reliability of CMOS circuits. This paper presents a reliability simulation study
based on R-D model on CMOS inverter circuit. HSPICE MOSRA model together with the Predictive
Technology Model (PTM) was used as to incorporate the NBTI model in the circuit reliability simulation
study for different technology nodes. PTM of High Performance (HP) models of 16nm, 22nm, 32nm
and 45nm were used in this simulation study. The atomic hydrogen based model was integrated in the
simulation. The results show that in a CMOS inverter circuit, the threshold voltage shift of p-MOSFET
under NBTI stressing increased as the year progressed.. The threshold voltage shift was observed to
increase up to 45.1% after 10 years of operation. The time exponent, n ~ 0.232 of the threshold voltage
shift observed indicates that the defect mechanism contributed to the degradation is atomic hydrogen.
The propagation delay increased to 19.5% over a 10-year period. s up to 19.5% from the zero year
of operation until 10 years of the operation. In addition, the time propagation delay increased as year
increased when the technology nodes smaller. The finding is important for understanding reliability
issues related to advanced technology nodes in CMOS circuits study.
Evaluation of two types of leukocyte removal filters on transfusion dependent thalassaemics

Jamal R, Mazeni NR, Hussin H

Malays J Pathol, 2000 Dec;22(2):79-83.
PMID: 16329539

The advent of leukocyte filters has enabled effective removal of leukocytes from certain blood products thus avoiding many adverse effects of blood transfusion. Many different materials have been incorporated into these filters to achieve >95% leukocyte removal. In this study we evaluated the efficacy of leukocyte removal of two different filters, using actual bedside transfusion settings involving patients with transfusion dependent thalassaemia. Fifty-one transfusion events were randomised to use either a polyurethane filter or a non-woven polyester filter. We found that the two filters achieved 98.4% and 96.2% leukocyte removal respectively (p = 0.022). We also found no significant correlation between pre-filtration white blood cell count and the volume transfused with the efficacy of leukodepletion. No untoward events or transfusion reactions were observed during the study.
Silent bony calcification of coronaries in an adolescent--an unusual case

Murty OP, Mun KS, Hussin H

J Forensic Leg Med, 2008 Jan;15(1):37-41.
PMID: 18309549

This is a case report of 16-year-old adolescent school boy who died due to unusual calcification of coronary arteries. He died while cycling with his friends. While cycling fast he fell. He was brought dead to hospital. At times unsuspected cardiac lesions cause sudden death during extraneous physical activities in healthy persons. Sudden death in adolescents is not very common. It is an unusual case as apparently healthy adolescent boy actively participating in sports had stony hard coronary arteries. The coronaries showed advanced calcification and early bone formation. The myocardial septum had extensive fibrosis. The pathogenesis and other possible similar conditions are also discussed in the report.
Fulltext Effects of gate stack structural and process defectivity on high-k dielectric dependence of NBTI reliability in 32 nm technology node PMOSFETs

Hussin H, Soin N, Bukhori MF, Hatta SW, Wahab YA

ScientificWorldJournal, 2014;2014:490829.
PMID: 25221784 DOI: 10.1155/2014/490829

We present a simulation study on negative bias temperature instability (NBTI) induced hole trapping in E' center defects, which leads to depassivation of interface trap precursor in different geometrical structures of high-k PMOSFET gate stacks using the two-stage NBTI model. The resulting degradation is characterized based on the time evolution of the interface and hole trap densities, as well as the resulting threshold voltage shift. By varying the physical thicknesses of the interface silicon dioxide (SiO2) and hafnium oxide (HfO2) layers, we investigate how the variation in thickness affects hole trapping/detrapping at different stress temperatures. The results suggest that the degradations are highly dependent on the physical gate stack parameters for a given stress voltage and temperature. The degradation is more pronounced by 5% when the thicknesses of HfO2 are increased but is reduced by 11% when the SiO2 interface layer thickness is increased during lower stress voltage. However, at higher stress voltage, greater degradation is observed for a thicker SiO2 interface layer. In addition, the existence of different stress temperatures at which the degradation behavior differs implies that the hole trapping/detrapping event is thermally activated.

Malays J Pathol, 2021 Apr;43(1):49-54.
PMID: 33903305

INTRODUCTION: Hedgehog (HH) pathway is an important signalling cascade for growth and patterning during embryonic development. Constitutive activation of Hedgehog pathway can be found in various types of malignancies including medulloblastoma, basal cell carcinoma, gastrointestinal, breast, pancreatic, prostate cancer and leukaemia. Little is known about the expression and role of Hedgehog signalling in bladder cancer.
MATERIALS AND METHODS: The purpose of this study was to investigate the immunohistochemical expression of SMO in 112 bladder cancer cases and determine their association with demographic and clinicopathological parameters. Bladder cancer tissues were obtained from the Hospital Kuala Lumpur.
RESULTS: SMO was expressed in the cytoplasm of all cases of bladder cancer. 6 cases (5.4%) showed low expression, while 106 cases (94.6%) showed high expression. Positive expression of SMO protein was correlated with a few variables which include grade and stage of tumour, lymph node metastasis and distant metastasis. SMO expression showed statistically significant association with higher grade (p=0.001) and higher stage (p=0.042) of bladder cancer. SMO expression also showed borderline association with lymph node metastasis (p=0.056).
CONCLUSION: These findings indicate that SMO expression may be a poor prognostic marker in bladder cancer.

Tan KF, Adam F, Hussin H, Mohd Mujar NM

Epidemiol Health, 2021;43:e2021038.
PMID: 34044478 DOI: 10.4178/epih.e2021038

This study compared breast cancer survival and the prognostic factors across different age groups of women in Penang, Malaysia. Data on 2,166 women with breast cancer who had been diagnosed between 2010 and 2014 were extracted from the Penang Breast Cancer Registry and stratified into 3 age groups: young (< 40 years old), middle-aged (40-59 years old), and elderly (≥ 60 years). The overall and relative survival rates were calculated using the life table method, median survival time was calculated using the Kaplan-Meier method, and comparisons between groups were conducted using the log-rank test. Prognostic factors were analyzed using a Cox proportional hazards model. The 5-year overall and breast cancer-specific survival rates for women with breast cancer in Penang were 72.9% and 75.2%, with a mean survival time of 92.5 months and 95.1 months, respectively. The 5-year breast cancer-specific survival rates for young, middle-aged, and elderly women were 74.9%, 77.8%, and 71.4%, respectively, with a mean survival time of 95.7 months, 97.5 months, and 91.2 months. There was a significant difference in breast cancer survival between age groups, with elderly women showing the lowest survival rate, followed by young and middle-aged women. Disease stage was the most prominent prognostic factor for all age groups. Survival rates and prognostic factors differed according to age group. Treatment planning for breast cancer patients should be age-specific to promote better cancer care and survival.

Mohamed NA, Pathmanathan SG, Hussin H, Zaini AB

J Infect Dev Ctries, 2018 Feb 28;12(2):102-108.
PMID: 31825911 DOI: 10.3855/jidc.9634

INTRODUCTION: Invasive Candida infections cause significant mortality and morbidity worldwide. Information on recent trends in species distribution and antifungal resistance in local settings is essential.
METHODOLOGY: Yeast isolates identified through standard culture methods throughout 2014 and 2015 from Hospital Ampang, Malaysia were retrospectively studied. The antifungal susceptibility of Candida species was determined using colorimetric broth microdilution method and MIC values interpreted according to CLSI breakpoints.
RESULTS: Out of all the 149 yeast cultures collected, most were from blood (55.7%) and respiratory specimens (33.6%). Candida tropicalis was the most common (28.9%), followed by C. albicans (26.2%), C. parapsilosis (15.4%), C. glabrata (14.1%), Crytococcus neoformans (6.7%), Trichosporon asahi (3.4%), C. krusei (2.0%), C. famata, C. rugose, C. guilliermondii, C. dublinensis and Trichosporon spp. (0.7% each). Occurrence of C. tropicalis in candidaemia cases was significantly associated to presence of an underlying haematological disorder, while C. albicans isolates in blood were significantly found in absence of such disorders. The four most common Candida species isolated showed high susceptibility to amphotericin B (100%), anidulafungin (100%), micafungin (100%), caspofungin (98.4%), flucytosine (98.4%) and voriconazole (84.1%). However, drug susceptibility to itraconazole and fluconazole was comparatively lower (57.9% and 72.2%, respectively). C. glabrata and C. tropicalis were the least susceptible to these azoles.
CONCLUSION: Prevalence of the high number of non-albicans Candida species with slight predominance of C. tropicalis over C. albicans was observed. Low susceptibility to itraconazole among C. glabrata and C. tropicalis isolates and to fluconazole among C. glabrata isolates warrants for continued surveillance to monitor emerging antifungal resistance.

Microb Drug Resist, 2018 Oct;24(8):1108-1116.
PMID: 29437541 DOI: 10.1089/mdr.2017.0258

Pseudomonas aeruginosa infections account for high morbidity and mortality rates worldwide. Increasing resistance toward β-lactams, especially carbapenems, poses a serious therapeutic challenge. However, the multilocus sequence typing (MLST) of extended-spectrum beta lactamase (ESBL)- and carbapenemase-producing clinical P. aeruginosa has not been reported in Malaysia. This study aimed to determine the antibiotic susceptibility profiles, resistance genes, pulsotypes, and sequence types (STs) of clinical P. aeruginosa from a Malaysian tertiary hospital. These characteristics were analyzed by disk diffusion, minimum inhibitory concentration, polymerase chain reaction, pulsed-field gel electrophoresis (PFGE), and MLST for 199 nonreplicate clinical strains. The susceptibility of the strains toward the carbapenems and piperacillin-tazobactam was the lowest (≤90%), while ≥90% of the strains remained susceptible to all other classes of antimicrobial agents tested. The multidrug-resistant strains displayed high level resistance to cephalosporins (48 to ≥256 mg/L) and carbapenems (4-32 mg/L). Eleven strains harbored class 1 integrons containing blaGES-13, blaVIM-2, blaVIM-6, blaOXA-10, aacA(6')-Ib, aacA(6')-II, aadA6, and gcuD gene cassettes. Extra-integron genes, blaGES-20, blaIMP-4, blaVIM-2, and blaVIM-11, were also found. Overall, the maximum likelihood tree showed concordance in the clustering of strains having the same STs and PFGE clusters. ST708 was the predominant antibiotic-susceptible clone detected from the neonatal intensive care unit. The STs 235, 809, and 1076 clonal clusters consisted of multidrug resistant strains. ST235 is a recognized international high-risk clone. This is the first report of blaGES-13 and blaGES-20 ESBL-encoding gene variants and novel STs (STs 2329, 2335, 2337, 2338, 2340, and 2341) of P. aeruginosa in Malaysia.

Ramli NA, Iberahim S, Che Ismail AA, Hussin H

Caspian J Intern Med, 2023;14(2):237-248.
PMID: 37223288 DOI: 10.22088/cjim.14.2.237

BACKGROUND: Cancer-related anaemia is one of the main burdens in oncology, although the available data on its prevalence and treatment options such as blood transfusion are often contradictory. This study aimed to evaluate the prevalence of anaemia and the requirement for packed red blood cell (PRBC) transfusion among women with breast cancer (BC) and to determine the associated factors for chemotherapy-induced anaemia (CIA).
METHODS: This cross-sectional retrospective study conducted in Kelantan involved 104 newly diagnosed female BC patients from 2015 to 2016 who underwent chemotherapy. For statistical analysis, chi-square was used to compare between CIA and non-CIA groups. In addition, simple and multiple logistic regression were used to determine the association of the CIA.
RESULTS: Our study revealed that 34.6% (n=36) of patients had mild anaemia, and 59.6% (n=62) had normal haemoglobin at pre-chemotherapy. The prevalence of anaemia increased from 40.4% to 77% at the end of our study. About 30.8% of patients received PRBC transfusion during chemotherapy with mean haemoglobin before the first transfusion of 7.9 g/dl. CIA was observed in 54.8% of cases. There was no significant association between CIA concerning the patient characteristic, cancer characteristic, or cancer treatment.
CONCLUSION: We concluded that a significant proportion (40.4%) of BC patients was anaemic even before chemotherapy, with the red blood cell requirements up to 30.8% throughout chemotherapy. A larger prospective study is needed to determine the predictors for the CIA and subsequently improve patient management.

Awang Ahmad N, Lai SK, Suboh R, Hussin H

Malays J Med Sci, 2023 Oct;30(5):81-90.
PMID: 37928785 DOI: 10.21315/mjms2023.30.5.7

BACKGROUND: Mast cells influence tumour growth, neo-angiogenesis and the propensity for metastasis by contributing to innate and adaptive immune responses in the tumour microenvironment. The number of mast cells has increased in various malignant tumours and their abundance has been associated with either a favourable or unfavourable prognosis. This study investigated the significant difference in stromal mast cell density among multiple prognostic factor groups in invasive breast carcinoma.
METHODS: CD117 (c-KIT) antibodies were used to stain 160 formalin-fixed and paraffin-embedded invasive breast carcinoma tissues to demonstrate the presence of mast cells. Then the labelled mast cells were counted in 10 fields at 400× magnification and the mean value was used to represent the mast cell density.
RESULTS: The demographic distribution revealed that most patients were 40 years old or older (92.5%) and of Malay ethnicity (66.3%). With regard to prognostic factors, the most prevalent subtype was invasive carcinoma of no special type (80.6%), followed by tumour grade 3 (41.3%), T2 tumour size (63.1%), N0 lymph node stage (51.3%), presence of lymphovascular invasion (59.4%), positive oestrogen (64.4%) and progesterone receptors (53.1%), and negative human epidermal growth factor receptor 2 (HER2) expression (75.0%). However, there was no significant difference in stromal mast cell density among the different demographic and prognostic factor groups in invasive breast carcinoma.
CONCLUSION: The findings from this study suggest that stromal mast cells do not play a significant role in preventing or promoting tumour growth in invasive breast carcinoma.

Malays J Med Sci, 2023 Dec;30(6):70-78.
PMID: 38239248 DOI: 10.21315/mjms2023.30.6.8

BACKGROUND: Colorectal carcinoma (CRC) is the third most common cancer globally. In Malaysia, CRC is most prevalent among males and the second most common cancer among females. The CRC arises mainly from the adenocarcinoma sequence. Poorly differentiated clusters (PDCs) and tumour budding (TB) are believed to represent sequential steps in tumour growth. Therefore, this study analysed the association between PDC grades with clinicopathological and demographic characteristics of CRC.
METHODS: A total of 47 CRC cases previously diagnosed by histopathological examination were reviewed for the presence of PDCs and graded accordingly. The association between PDC grades with clinicopathological and demographic characteristics was statistically analysed.
RESULTS: Out of the 47 cases with PDCs, most of them were of grade 3 (G3) (n = 27, 57.4%), followed by grade 2 (G2) (n = 13, 27.7%) and grade 1 (G1) (n = 7, 14.9%). Higher PDC grades (G2 and G3) were mainly observed in higher tumour stage (T); T3 (n = 26, 83.9%), T4 (n = 12, 92.3%), N1 (n = 20, 86.9%), N2 (n = 15, 100%). In addition, there was a significant association between PDC grades with the nodal stage (N) (P = 0.013) and the tumour, node and metastasis (TNM) stages (P = 0.012).
CONCLUSION: The PDC grades are useful for assessing the disease prognosis in CRC. A statistically significant association between PDC grades with N and TNM stages suggested that PDC grades are potential predictive parameters for invasive and metastatic risks in CRC.

PMID: 21874752 MyJurnal

Myeloid sarcoma (MS) is a rare extramedullary myeloid tumour. It has been reported in various sites, including lymph node, bone, skin, soft tissue, various organs and the CNS. It may precede or occur concurrently with acute myeloid leukemia. Urinary bladder involvement is extremely uncommon. We report a 70-year-old female who had MS of the urinary bladder, presented with frank and persistent hematuria associated with lower abdominal pain. She subsequently had tumour seeding in the abdominal skin via percutaneous suprapubic catheter. Tumours from both the urinary bladder and skin showed immature cells that were immunoreactive toward LCA (focal), MPO (strong), CD99 (weak) and CD117 (weak). Summary of cases in the literature is presented. The potential of its misdiagnosis and the useful markers for the diagnosis of MS are discussed.

Tumor suppression effect of Solanum nigrum polysaccharide fraction on Breast cancer via immunomodulation

Razali FN, Sinniah SK, Hussin H, Zainal Abidin N, Shuib AS

Int J Biol Macromol, 2016 Nov;92:185-193.
PMID: 27365117 DOI: 10.1016/j.ijbiomac.2016.06.079

A polysaccharide fraction from Solanum nigrum, SN-ppF3 was shown previously to have an immunomodulatory activity where it could possibly be used to enhance the host immune response in fighting cancer. The non-toxic SN-ppF3 was fed orally to breast tumor bearing-mice with concentrations of 250 and 500mg/kg for 10days. During the treatment period, size of the tumor and weight of the mice were monitored. At the end of the treatment, blood, tumor, spleen and thymus were harvested for physiological and immunological analyses. After the treatment, the tumor volume and tumor weight were significantly inhibited by 65% and 40%, respectively. Based on the histological observation, the treatment of SN-ppF3 resulted in the disruption of tumor cells morphology. The increase in infiltrating T cells, NK cells and macrophages were observed in tumor tissues of the treated mice, which partly explained the higher apoptosis tumor cells observed in the treated mice. Moreover, the level of TNF-α, IFN-γ and IL-4 were elevated, while the level of IL-6 was decreased significantly, in serum of the treated mice. These results suggested that tumor suppression mechanisms observed in SN-ppF3-treated mice were most probably due through enhancing the host immune response.

Data Brief, 2019 Feb;22:830-835.
PMID: 30766903 DOI: 10.1016/j.dib.2018.12.086

To identify the potential zones for gold mineralization at the Felda Chiku 3, Gua Musang, Kelantan, East coast Malaysia, twenty-one (21) geophysical survey lines were conducted at the proposed mineral exploration site using the pole - dipole of the electrical resistivity and induced polarization arrays to get the maximum depth of 150 m with 400 m survey length. From the resistivity and chargeability concentration maps, the potential mineralized zones as delineated, was observed to be dominantly concentrated towards the southwest and northern part of the area. The 3D resistivity and chargeability slice model present low resistivity values and high chargeability values that are well correlated which is palpable especially at the depths of 25 m and 50 m respectively. The data showed that the potential mineralized zones are trending approximately north-south directions. Forty (40) drilling locations were proposed for follow-up drilling based on the resistivity and chargeability models.

PMID: 34687904 DOI: 10.1016/j.jpag.2021.10.002

BACKGROUND: Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a congenital disorder characterized by underdevelopment of the uterus and vagina.
CASE: A 4-year-old girl was declared dead on arrival to the hospital with a history of chronic constipation since birth. Postmortem examination showed Müllerian remnants attached to abnormal fibrous tissue. The fibrous tissue extended from the descending colon to the rectum and connected to a urinary bladder duplication cyst. The fibrous tissue formed into a constricted band around the rectum. The cause of death was Streptococcus pyogenes sepsis with intestinal obstruction secondary to the rectal fibrotic band and urinary bladder duplication cyst.
SUMMARY AND CONCLUSION: MRKH syndrome is a rare congenital disorder, and the malformations rarely cause death. We describe the features of abnormal fibrous tissue and urinary bladder duplication cyst in a patient with MRKH syndrome.
