J Obstet Gynaecol Res, 2008 Jun;34(3):350-3.
PMID: 18686348

AIM: To compare the success, clinical outcomes, and maternal and neonatal complications between the Kiwi Omnicup and the Malmstrom metal cup in vacuum assisted delivery.
METHODS: This was a prospective randomized comparative trial. Women who required vacuum assisted vaginal delivery were randomized into the Kiwi Omnicup (KO) group and the Malmstrom metal cup (MM) group. The vacuum assisted deliveries were conducted according to hospital protocol. Details of the procedure and delivery outcomes including success and complications were analyzed.
RESULTS: One hundred and sixty-four women were recruited - 85 were assigned to vacuum assisted delivery using the KO and 79 the MM. One hundred percent delivery success was achieved with no significant differences between the two instruments in terms of maternal morbidity (P = 0.66). Six women in the MM group sustained post delivery complications in comparison to five in the KO group. Three babies were diagnosed with birth asphyxia in each group. More babies in the MM group were admitted to the Neonatal Intensive Care Unit (NICU) (10 babies versus 5 babies) and suffered complications (14 versus 12 babies), compared to the KO group, although the difference was not statistically significant. There were no intrapartum or neonatal deaths and of those admitted to the NICU, all were discharged within a week without any serious consequences.
CONCLUSION: Kiwi Omnicup is an effective alternative to the currently available Malmstrom metal cup for vacuum assisted delivery with no increase in maternal or neonatal morbidity or mortality.
Invasive squamous cell carcinoma arising from chromoblastomycosis

Jamil A, Lee YY, Thevarajah S

Med Mycol, 2012 Jan;50(1):99-102.
PMID: 21449695 DOI: 10.3109/13693786.2011.571295

Chromoblastomycosis is a chronic subcutaneous mycosis seen mainly in tropical regions. While malignant transformation rarely occurs, the present report describes a 69-year-old man with a 21-year history of chromoblastomycosis complicated by invasive squamous cell carcinoma requiring amputation of the affected limb. A review of previous reported cases shows malignancy arising after 20-30 years of infection in ≥60-year-old males who have received inadequate treatment of chromoblastomycosis and have had relapses. An immunocompromised state is not an associated feature of such cases. The extremities are commonly affected as carcinomas occur from the most chronic lesions which are generally found on these limbs.

Liew SC, Das-Gupta E, Wong SF, Lee N, Safdar N, Jamil A

Nutr J, 2012 Jan 05;11:1.
PMID: 22217364 DOI: 10.1186/1475-2891-11-1

BACKGROUND: The methylenetetrahydrofolate reductase (MTHFR) enzyme catalyzes the reduction of 5, 10-methylenetetrahydrofolate to 5-methyltetrahydrofolate and methyl donors. The methyl donors are required for the conversion of homocysteine to methionine. Mutation of MTHFR 677 C > T disrupts its thermostability therefore leads to defective enzyme activities and dysregulation of homocysteine levels.
METHODS: This case-control study (n = 367) was conducted to investigate the correlation of the MTHFR gene polymorphism [NM_005957] and psoriasis vulgaris amongst the Malaysian population. Overnight fasting blood samples were collected from a subgroup of consented psoriasis vulgaris patients and matched controls (n = 84) for the quantification of homocysteine, vitamin B12 and folic acid levels.
RESULTS: There was no significant increase of the MTHFR 677 C > T mutation in patients with psoriasis vulgaris compared with controls (χ(2) = 0.733, p = 0.392). No significant association between homocysteine levels and MTHFR gene polymorphism in cases and controls were observed (F = 0.91, df = 3, 80, p = 0.44). However, homocysteine levels in cases were negatively correlated with vitamin B12 (r = -0.173) and folic acid (r = -0.345) levels. Vitamin B12 and folic acid levels in cases were also negatively correlated (r = -0.164).
CONCLUSIONS: Our results indicate that there was no significant association between the MTHFR gene polymorphism and psoriasis vulgaris in the Malaysian population. There was no significant increase of the plasma homocysteine level in the psoriasis patients compared to the controls.
Fulltext Acne analysis, grading and computational assessment methods: an overview

Ramli R, Malik AS, Hani AF, Jamil A

Skin Res Technol, 2012 Feb;18(1):1-14.
PMID: 21605170 DOI: 10.1111/j.1600-0846.2011.00542.x

INTRODUCTION: This paper presents a comprehensive review of acne grading and measurement. Acne is a chronic disorder of the pilosebaceous units, with excess sebum production, follicular epidermal hyperproliferation, inflammation and Propionibacterium acnes activity. Most patients are affected with acne vulgaris, which is the prevalent type of acne. Acne vulgaris consists of comedones (whitehead and blackhead), papules, pustules, nodules and cysts.
OBJECTIVES: To review and identify the issues for acne vulgaris grading and computational assessment methods. To determine the future direction for addressing the identified issues.
METHODS: There are two main methods of assessment for acne severity grading, namely, lesion counting and comparison of patient with a photographic standard. For the computational assessment method, the emphasis is on computational imaging techniques.
RESULTS: Current acne grading methods are very time consuming and tedious. Generally, they rely on approximation for counting lesions and hence the assessment is quite subjective, with both inter and intra-observer variability. It is important to accurately assess acne grade to evaluate its severity as this influences treatment selection and assessment of response to therapy. This will further help in better disease management and more efficacious treatment.
CONCLUSION: Semi-automated or automated methods based on computational imaging techniques should be devised for acne grade assessment.

Angiogenesis has been reported to be one of the contributory factors to the pathogenesis of psoriasis vulgaris. This study aims to compare the expression of different angiogenesis growth factors namely (1) the vascular endothelial growth factor (VEGF) subfamily: A, B, C, D and placenta growth factor (PlGF); (2) nerve growth factor (NGF) and (3) von Willebrand factor (vWFr) in the skins of patients with psoriasis vulgaris and non-psoriatic volunteers.

Mismanagement of cat bite wound: lessons to learn

Muthupalaniappen L, Siti Aishah MA, Wong YP, Jamil A

Clin Ter, 2013 May-Jun;164(3):225-7.
PMID: 23868624 DOI: 10.7417/CT.2013.1553

Animal inflicted wounds, left untreated may result in chronic bacterial or fungal infection. Clinical features of these infections may overlap leading to a delay in diagnosis and treatment. We report a case of chronic non-healing cat bite wound treated with several antibiotics without improvement. Later patient developed the classical "sporotrichoid spread" and a presumptive diagnosis of sporotrichosis was made. Laboratory investigation for fungal culture and skin biopsy failed to identify the underlying pathogen. A trial of oral antifungal agent resulted in complete recovery of the lesions implicating fungus as the causative pathogen. Physicians should have a high index of suspicion for fungal infections when managing animal inflicted wounds.

Angiogenesis, or new blood vessel formation from existing one, plays both beneficial and detrimental roles in living organisms in different aspects. Vascular endothelial growth factor (VEGF), a signal protein, well established as key regulator of vasculogenesis and angiogenesis. VEGF ensures oxygen supply to the tissues when blood supply is not adequate, or tissue environment is in hypoxic condition. Limited expression of VEGF is necessary, but if it is over expressed, then it can lead to serious disease like cancer. Cancers that have ability to express VEGF are more efficient to grow and metastasize because solid cancers cannot grow larger than a limited size without adequate blood and oxygen supply. Anti-VEGF drugs are already available in the market to control angiogenesis, but they are often associated with severe side-effects like fetal bleeding and proteinuria in the large number of patients. To avoid such side-effects, new insight is required to find potential compounds as anti-VEGF from natural sources. In the present investigation, molecular docking studies were carried out to find the potentiality of Withaferin A, a key metabolite of Withania somnifera, as an inhibitor of VEGF.

Different parts of the medicinal plant Zanthoxylum budrunga Wall enjoy a variety of uses in ethnobotanical practice in Bangladesh. In the present study, a number of phytochemical and pharmacological investigations were done on the ethanol extract of Z. budrunga seeds (ZBSE) to evaluate its antinociceptive and antioxidant potential. ZBSE was also subjected to HPLC analysis to detect the presence of some common antioxidants. In acetic acid induced writhing test in mice, ZBSE showed 65.28 and 74.30% inhibition of writhing at the doses of 250 and 500 mg/kg and the results were statistically significant (P < 0.001). In hot-plate test, ZBSE raised the pain threshold significantly (P < 0.001) throughout the entire observation period. In DPPH scavenging assay, the IC50 of ZBSE was observed at 82.60 μg/mL. The phenolic content was found to be 338.77 mg GAE/100 g of dried plant material. In reducing power assay, ZBSE showed a concentration dependent reducing ability. HPLC analysis indicated the presence of caffeic acid with a concentration of 75.45 mg/100 g ZBSE. Present investigation supported the use of Zanthoxylum budrunga seed in traditional medicine for pain management. Constituents including caffeic acid and other phenolics might have some role in the observed activity.
Fulltext Evaluation of antidiabetic and antioxidant properties of Brucea javanica seed

Ablat A, Mohamad J, Awang K, Shilpi JA, Arya A

ScientificWorldJournal, 2014;2014:786130.
PMID: 24688431 DOI: 10.1155/2014/786130

The ethanol extract of B. javanica seed was fractionated with solvents of different polarities and tested for antioxidant activities by several assays including DPPH radical scavenging activity, ferric reducing antioxidant power (FRAP), ferrous ion chelating activity (FCA), and nitric oxide radical scavenging activity (NORSA) along with their polyphenolic contents. Antidiabetic activity was evaluated both in vitro and in vivo using a glycogen phosphorylase α (GPα) inhibition assay and oral glucose tolerance test (OGTT) in nondiabetic rats. The ethyl acetate fraction (EAF), rich in tannin, exhibited the strongest antioxidant activities to DPPH, FRAP, and NORSA, except for FCA. The EAF also exerted a dose-depended inhibition of GPα (IC50 = 0.75 mg/ml). Further evaluation of hypoglycemic effect on OGGT indicated that rats treated with EAF (125 mg/kg bw) showed a 39.91% decrease (P < 0.05) in blood glucose levels at 30 min, and continuous fall (P < 0.05) of 28.89% and 20.29% was observed in the following hours (60 and 90 min) compared to the normal control during OGTT. The EAF was applied to polyamide column chromatography, and the resulting tannin-free fraction was tested for both GPα inhibition and antioxidant (DPPH only) activity. The GP α inhibitory activity was retained, while antioxidant activity was lost (4.6-fold) after tannin removal. These results concluded that the GPα inhibitory activity initially detected was primarily due to the compounds other than tannins, whereas antioxidant activity was mainly due to the tannins.
Fulltext A Quantum Chemical and Statistical Study of Cytotoxic Activity of Compounds Isolated from Curcuma zedoaria

Hamdi OA, Anouar el H, Shilpi JA, Trabolsy ZB, Zain SB, Zakaria NS, et al.

Int J Mol Sci, 2015 Apr 27;16(5):9450-68.
PMID: 25923077 DOI: 10.3390/ijms16059450

A series of 21 compounds isolated from Curcuma zedoaria was subjected to cytotoxicity test against MCF7; Ca Ski; PC3 and HT-29 cancer cell lines; and a normal HUVEC cell line. To rationalize the structure-activity relationships of the isolated compounds; a set of electronic; steric and hydrophobic descriptors were calculated using density functional theory (DFT) method. Statistical analyses were carried out using simple and multiple linear regressions (SLR; MLR); principal component analysis (PCA); and hierarchical cluster analysis (HCA). SLR analyses showed that the cytotoxicity of the isolated compounds against a given cell line depend on certain descriptors; and the corresponding correlation coefficients (R2) vary from 0%-55%. MLR results revealed that the best models can be achieved with a limited number of specific descriptors applicable for compounds having a similar basic skeleton. Based on PCA; HCA and MLR analyses; active compounds were classified into subgroups; which was in agreement with the cell based cytotoxicity assay.

Hydrocortisone (HC) is a topical glucocorticoid for the treatment of atopic dermatitis (AD); the local as well as systemic side effects limit its use. Hydroxytyrosol (HT) is a polyphenol present in olive oil that has strong antimicrobial and antioxidant activities. HC-HT coloaded chitosan nanoparticles (HC-HT CSNPs) were therefore developed to improve the efficacy against AD. In this study, HC-HT CSNPs of 235 ± 9 nm in size and with zeta potential +39.2 ± 1.6 mV were incorporated into aqueous cream (vehicle) and investigated for acute dermal toxicity, dermal irritation, and repeated dose toxicity using albino Wistar rats. HC-HT CSNPs exhibited LD50 > 125 mg/body surface area of active, which is 100-fold higher than the normal human dose of HC. Compared with the commercial formulation, 0.5 g of HC-HT CSNPs did not cause skin irritation, as measured by Tewameter®, Mexameter®, and as observed visually. Moreover, no-observed-adverse-effect level was observed with respect to body weight, organ weight, feed consumption, blood hematological and biochemical, urinalysis, and histopathological parameters at a dose of 1000 mg/body surface area per day of HC-HT CSNPs for 28 days. This in vivo study demonstrated that nanoencapsulation significantly reduced the toxic effects of HC and this should allow further clinical investigations.
Fulltext Spectrofluorometric and molecular docking studies on the binding of curcumenol and curcumenone to human serum albumin

Hamdi OA, Feroz SR, Shilpi JA, Anouar el H, Mukarram AK, Mohamad SB, et al.

Int J Mol Sci, 2015;16(3):5180-93.
PMID: 25756376 DOI: 10.3390/ijms16035180

Curcumenol and curcumenone are two major constituents of the plants of medicinally important genus of Curcuma, and often govern the pharmacological effect of these plant extracts. These two compounds, isolated from C. zedoaria rhizomes were studied for their binding to human serum albumin (HSA) using the fluorescence quench titration method. Molecular docking was also performed to get a more detailed insight into their interaction with HSA at the binding site. Additions of these sesquiterpenes to HSA produced significant fluorescence quenching and blue shifts in the emission spectra of HSA. Analysis of the fluorescence data pointed toward moderate binding affinity between the ligands and HSA, with curcumenone showing a relatively higher binding constant (2.46 × 105 M-1) in comparison to curcumenol (1.97 × 104 M-1). Cluster analyses revealed that site I is the preferred binding site for both molecules with a minimum binding energy of -6.77 kcal·mol-1. However, binding of these two molecules to site II cannot be ruled out as the binding energies were found to be -5.72 and -5.74 kcal·mol-1 for curcumenol and curcumenone, respectively. The interactions of both ligands with HSA involved hydrophobic interactions as well as hydrogen bonding.

Garo Hills represents one of earliest human habitation in Bangladesh preserving its ancient cultures due to the geographic location. It is situated in the most northern part of Durgapur sub-district having border with Meghalaya of India. Durgapur is rich in ethnic diversity with Garo and Hajong as the major ethnic groups along with Bangalee settlers from the mainstream population. Thus the ethnomedicinal practice in Garo Hills is considered rich as it encompasses three different groups. Present survey was undertaken to compile the medicinal plant usage among the various communities of the Garo Hills.

Chem Biodivers, 2016 May;13(5):483-503.
PMID: 26970405 DOI: 10.1002/cbdv.201400373

Chisocheton is one of the genera of the family Meliaceae and consists of ca. 53 species; the distribution of most of those are confined to the Indo-Malay region. Species of broader geographic distribution have undergone extensive phytochemical investigations. Previous phytochemical investigations of this genus resulted in the isolation of mainly limonoids, apotirucallane, tirucallane, and dammarane triterpenes. Reported bioactivities of the isolated compounds include cytotoxic, anti-inflammatory, antifungal, antimalarial, antimycobacterial, antifeedant, and lipid droplet inhibitory activities. Aside from chemistry and biological activities, this review also deals briefly with botany, distribution, and uses of various species of this genus.

In-vivo dermal pharmacokinetics, efficacy, and safety of skin targeting nanoparticles for corticosteroid treatment of atopic dermatitis

Siddique MI, Katas H, Amin MC, Ng SF, Zulfakar MH, Jamil A

Int J Pharm, 2016 Jun 30;507(1-2):72-82.
PMID: 27154252 DOI: 10.1016/j.ijpharm.2016.05.005

The objective of this study was to investigate the in-vivo behavior of topically applied cationic polymeric chitosan nanoparticles (CSNPs) loaded with anti-inflammatory (hydrocortisone, HC) and antimicrobial (hydroxytyrosol, HT) drugs, to elucidate their skin targeting potential for the treatment of atopic dermatitis (AD). Compared to the commercial formulation, the HC-HT loaded CSNPs showed significantly improved drug penetration into the epidermal and dermal layers of albino Wistar rat skin without saturation. Dermal pharmacokinetic of CSNPs with a size of 228.5±7nm and +39±5mV charges revealed that they penetrated 2.46-fold deeper than the commercial formulation did, and had greater affinity at the skin target site without spreading to the surrounding tissues, thereby providing substantial safety benefits. In repeated dermal application toxicity studies, the HC-HT CSNPs showed no evidence of toxicity compared to the commercial formulation, which induced skin atrophy and higher liver enzyme levels. In conclusion, the positively charged HC-HT CSNP formulation exhibited promising local delivery and virtually no treatment-related toxicities, suggesting it may be an efficient and viable alternative for commercially available AD treatments.
