PMID: 33883974 DOI: 10.1155/2021/9725903

2,6-Bis-(4-hydroxyl-3-methoxybenzylidine) cyclohexanone (BHMC), a synthetic curcuminoid analogue, has been shown to exhibit anti-inflammatory properties in cellular models of inflammation and improve the survival of mice from lethal sepsis. We further evaluated the therapeutic effect of BHMC on acute airway inflammation in a mouse model of allergic asthma. Mice were sensitized and challenged with ovalbumin (OVA), followed by intraperitoneal administration of 0.1, 1, and 10 mg/kg of BHMC. Bronchoalveolar lavage fluid, blood, and lung samples were collected, and the respiratory function was measured. OVA sensitization and challenge increased airway hyperresponsiveness (AHR) and pulmonary inflammation. All three doses of BHMC (0.1-10 mg/kg) significantly reduced the number of eosinophils, lymphocytes, macrophages, and neutrophils, as well as the levels of Th2 cytokines (IL-4, IL-5 and IL-13) in bronchoalveolar lavage fluid (BALF) as compared to OVA-challenged mice. However, serum level of IgE was not affected. All three doses of BHMC (0.1-10 mg/kg) were effective in suppressing the infiltration of inflammatory cells at the peribronchial and perivascular regions, with the greatest effect observed at 1 mg/kg which was comparable to dexamethasone. Goblet cell hyperplasia was inhibited by 1 and 10 mg/kg of BHMC, while the lowest dose (0.1 mg/kg) had no significant inhibitory effect. These findings demonstrate that BHMC, a synthetic nonsteroidal small molecule, ameliorates acute airway inflammation associated with allergic asthma, primarily by suppressing the release of inflammatory mediators and goblet cell hyperplasia to a lesser extent in acute airway inflammation of allergic asthma.

Fulltext A Systematic Review of the Prevalence of Atopic Diseases in Children on the Arabian Peninsula

Al-Herz W

Med Princ Pract, 2018;27(5):436-442.
PMID: 30149382 DOI: 10.1159/000493267

OBJECTIVES: To study the available data on the prevalence of atopic diseases and food allergy in children living on the Arabian Peninsula.
METHODS: A PubMed search for relevant published articles was conducted using the following search terms singly or in combination: "atopy," "atopic disease," "atopic disorder," "International Study of Asthma and Allergies in Childhood," "ISAAC," "asthma," "allergic rhinitis," "eczema," and "food allergy" in combination with the names of countries of the Arabian Peninsula (Kuwait, United Arab Emirates, Bahrain, Qatar, Oman, Kingdom of Saudi Arabia, and Yemen). The search captured studies published up to December 2017.
RESULTS: A total of 8 publications reporting prevalence rates of any type of atopic disease in children in 7 countries of the Arabian Peninsula were retrieved. The prevalence of all atopic disorders was comparable between countries of the Arabian Peninsula. The overall prevalence of asthma ranged from 8 to 23%, while the reported prevalence of eczema ranged from 7.5 to 22.5%. There was great variation in the prevalence rates of rhinoconjunctivitis, which ranged from 6.3 to 30.5%. The prevalence of food allergy (8.1%) was reported for 1 country only, the United Arab Emirates.
CONCLUSIONS: The reported overall rates of atopic disease in countries of the Arabian Peninsula are comparable to those reported in other industrialized countries. This is probably related to the good economic status in the region, which is reflected in the living standards and lifestyle. Further, genetic factors, such as factors related to gene polymorphism, and the high rate of consanguinity in the region may contribute to the higher prevalence of atopic diseases.

A contemporary review of seafood allergy

Hajeb P, Selamat J

Clin Rev Allergy Immunol, 2012 Jun;42(3):365-85.
PMID: 22045217 DOI: 10.1007/s12016-011-8284-9

Seafood is common item in the world diet; Asian countries have the highest rates of fish consumption in the world, which is higher than world average. Several studies have been conducted on the epidemiology and clinical characteristics of seafood allergy in different countries, and some of the fish and seafood allergens unique to those regions have been characterized. Review on published data showed that seafood allergy is very ubiquitous in some regions of the world. Fish and shellfish are the most common seafood that cause adverse allergic reactions among nations; the symptoms ranged from oral allergy syndromes to urticaria and anaphylaxis. The major identified allergens are parvalbumin in fish and tropomyosin in shellfish. Nevertheless, such studies are lacking from some regions with high fish and seafood consumption. Furthermore, the published data are mostly from small groups of populations, which large-scale epidemiological studies need to be performed.

Dellemin NA, Zahari Z, Ahmad Hassali MA, Rashid SA

Pak J Pharm Sci, 2020 May;33(3):1057-1061.
PMID: 33191229

Recent years, the prevalence of paracetamol allergy becomes great concerns. However, data on knowledge, attitude and perception towards allergic reactions of paracetamol are lacking. This study aimed to investigate knowledge, attitude, and perception towards allergic reactions of paracetamol (KAP-ARP). A cross-sectional survey was conducted using a validated self-administered questionnaire around Pasar Siti Khadijah, Kelantan from February 2016 to January 2017 among the general population. A total of 177 respondents participated in this study. The mean percentage scores for knowledge, attitude and perception towards allergic reactions of paracetamol were 31.7% (SD 23.6), 53.1% (SD 19.2) and 53.3% (SD 23.9), respectively. This study revealed that respondents demonstrated a poor level of knowledge, a fair level of attitude and negative perception towards allergic reactions of paracetamol. These results may lay a basis for conducting a study of knowledge, attitude and perception towards allergic reactions among general population in other different setting or around Malaysia.

A dietary pattern of frequent plant-based foods intake reduced the associated risks for atopic dermatitis exacerbation: Insights from the Singapore/Malaysia cross-sectional genetics epidemiology cohort

Lim JJ, Reginald K, Say YH, Liu MH, Chew FT

BMC Public Health, 2023 Sep 19;23(1):1818.
PMID: 37726698 DOI: 10.1186/s12889-023-16736-y

BACKGROUND: The prevalence of atopic dermatitis (AD) has been increasing in recent years, especially in Asia. There is growing evidence to suggest the importance of dietary patterns in the development and management of AD. Here, we seek to understand how certain dietary patterns in a Singapore/Malaysia population are associated with various risks of AD development and exacerbation.
METHODS: A standardized questionnaire following the International Study of Asthma and Allergies in Childhood (ISAAC) guidelines was investigator-administered to a clinically and epidemiology well-defined allergic cohort of 13,561 young Chinese adults aged 19-22. Information on their sociodemographic, lifestyle, dietary habits, and personal and family medical atopic histories were obtained. Allergic sensitization was assessed by a skin prick test to mite allergens. Spearman's rank-order correlation was used to assess the correlation between the intake frequencies of 16 food types. Dietary patterns were identified using principal component analysis. Four corresponding dietary scores were derived to examine the association of identified dietary patterns with allergic sensitization and AD exacerbations through a multivariable logistic regression that controlled for age, gender, parental eczema, BMI, and lifestyle factors.
RESULTS: The correlation is the strongest between the intake of butter and margarine (R = 0.65). We identified four dietary patterns, "high-calorie foods", "plant-based foods", "meat and rice", and "probiotics, milk and eggs", and these accounted for 47.4% of the variance in the dietary habits among the subjects. Among these patterns, moderate-to-high intake of "plant-based foods" conferred a negative association for chronic (Adjusted odds ratio (AOR): 0.706; 95% confidence interval (CI): 0.589-0.847; p

Fulltext A review of oral food challenges in children presenting to a single tertiary centre with perceived or true food allergies

Thalayasingam M, Loo EX, Tan MM, Bever HV, Shek LP

Singapore Med J, 2015 Nov;56(11):622-5.
PMID: 26668407 DOI: 10.11622/smedj.2015171

The prevalence of perceived food allergies exceeds that of true food allergies. Unnecessary food avoidance may increase parental and patient anxiety, reduce quality of life and increase the risk of nutritional deficiency. An oral food challenge (OFC) can provide an objective measure regarding the presence or absence of food allergies in a child. This study reviews the indications for and outcomes of OFCs performed on children.

Fulltext A second international cooperative investigation into tioacetazone side effects

Miller AB, Nunn AJ, Robinson DK, Fox W, Somasundaram PR, Tall R

Bull World Health Organ, 1972;47(2):211-27.
PMID: 4118761

As part of a large-scale international cooperative investigation into the side effects of thioacetazone-containing regimens in the treatment of tuberculosis, an evaluation has been made of the variation in the frequency of side effects between different countries and between different centres in the same country and of the likely reasons for this variation. In 3 countries patients of different racial origin were under observation in the same hospital. Over a 12-week period of treatment there was considerable variation between the countries and centres in the overall frequency of side effects and of those leading to a major departure from prescribed treatment, the variation being similar for the two thioacetazone-containing regimens and for the streptomycin plus isoniazid control regimen, though at a lower level for the latter. In Malaysia, Singapore, and Trinidad, where different racial groups were under treatment, there was no clear indication that race was an important factor in explaining the differences between countries, except for cutaneous side effects in Trinidad and possibly in Malaysia.It is concluded that the differences in the frequency of side effects to thioacetazone-containing regimens probably result from variation in the closeness of supervision of patients, in the recording and interpretation of side effects, and in environmental factors including the previous use of other medicaments or exposure to sensitizing substances.

Fulltext A simple design for microwave assisted digestion vessel with low reagent consumption suitable for food and environmental samples

Gholami M, Behkami S, Zain SM, Bakirdere S

Sci Rep, 2016 11 17;6:37186.
PMID: 27853264 DOI: 10.1038/srep37186

The objective of this work is to prepare a cost-effective, low reagent consumption and high performance polytetrafluoroethylene (PTFE) vessel that is capable to work in domestic microwave for digesting food and environmental samples. The designed vessel has a relatively thicker wall compared to that of commercial vessels. In this design, eight vessels are placed in an acrylonitrile butadiene styrene (ABS) holder to keep them safe and stable. This vessel needs only 2.0 mL of HNO3 and 1.0 mL H2O2 to digest 100 mg of biological sample. The performance of this design is then evaluated with an ICP-MS instrument in the analysis of the several NIST standard reference material of milk 1849a, rice flour 1568b, spinach leave 1570a and Peach Leaves 1547 in a domestic microwave oven with inverter technology. Outstanding agreement to (SRM) values are observed by using the suggested power to time microwave program, which simulates the reflux action occurring in this closed vessel. Taking into account the high cost of commercial microwave vessels and the volume of chemicals needed for various experiments (8-10 mL), this simple vessel is cost effective and suitable for digesting food and environmental samples.

Fulltext A single epitope of Epstein-Barr Virus stimulate IgG production in mice

Widodo, Pristiwanto B, Rifa'i M, Mustafa I, Huyop FZ

Ann Med Surg (Lond), 2018 Nov;35:55-58.
PMID: 30294429 DOI: 10.1016/j.amsu.2018.09.014

Background: Epstein-Barr virus (EBV) is closely associated with the high incidence of nasopharyngeal carcinoma in worldwide. Vaccination is one strategy with the potential to prevent the occurrence of EBV-associated cancers, but a suitable vaccine is yet to be licensed. Much vaccine development research focuses on the GP350/220 protein of EBV as it contains an immunogenic epitope at residues 147-165, which efficiently stimulates IgG production in vitro. We examined the ability of this epitope (EBVepitope) to induce IgG production in mice.
Methods: The antibody binding pattern of the epitope was analyzed using bioinformatics tools. The IgG production in mice were examined by FACS Calibur™ Flow cytometer.
Results: The epitope bound the 72A1 monoclonal antibody at the same site as GP350/220 protein, indicating that the epitope should stimulate B cells to produce antibody. Moreover, in vivo administration of EBVepitope successfully induced IgG expression from B cells, compared with controls. Further investigation indicated that the relative number of B cells expressing IgE in EBVepitope-treated mice was lower than controls.
Conclusions: Our data suggest that this EBV GP350 epitope is able to induce IgG expression in vivo without causing allergic reactions, and represents a potential EBV vaccine candidate.

Fulltext AN INVESTIGATION INTO THE PERFORMANCE OF THE MULTILAYER PERCEPTRON ARCHITECTURE OF DEEP LEARNING IN FORECASTING STOCK PRICES

ASSUNTA MALAR PATRICK VINCENT, HASSILAH SALLEH

UMT Journal of Undergraduate Research, 2021;3(2):61-68.
MyJurnal

A wide range of studies have been conducted on deep learning to forecast time series data. However, very few researches have discussed the optimal number of hidden layers and nodes in each hidden layer of the architecture. It is crucial to study the number of hidden layers and nodes in each hidden layer as it controls the performance of the architecture. Apart from that, in the presence of the activation function, diverse computation between the hidden layers and output layer can take place. Therefore, in this study, the multilayer perceptron (MLP) architecture is developed using the Python software to forecast time series data. Then, the developed architecture is applied on the Apple Inc. stock price due to its volatile characteristic. Using historical prices, the accuracy of the forecast is measured by the different activation functions, number of hidden layers and size of data. The Keras deep learning library, which can be found in the Python software, is used to develop the MLP architecture to forecast the Apple Inc. stock price. The developed model is then applied on different cases, namely different sizes of data, different activation functions, different numbers of hidden layers of up to nine layers, and different numbers of nodes in each hidden layer. Then, the metrics mean squared error (MSE), mean absolute error (MAE) and root-mean-square error (RMSE) are employed to test the accuracy of the forecast. It is found that the architecture with rectified linear unit (ReLU) outperformed in every hidden layer and each case with the highest accuracy. To conclude, the optimal number of hidden layers differs in every case as there are other influencing factors.

Fulltext Absence of milk-specific IgE in infants with cow's milk protein-sensitive enteropathy

Yadav M, Iyngkaran N, Seow IKG

Med J Malaysia, 1983 Dec;38(4):266-71.
PMID: 6599980

Infants, one to 56-weeks-old, presenting with persistent diarrhoea were placed on a diet free of cow's milk protein which improved their clinical condition. Six weeks later, 67 infants were challenged with a low-lactose cow's milk formula and jejunal biopsy was taken before and 24-hours after challenge. On the basis of histological changes in the intestinal mucosa and development of clinical symptoms the infants were categorised into three groups: Group 1 (n = 16) with no clinical or mucosal abnormality, Group 2 (n = 20) with mucosal abnormality but lacking clinical symptoms, and Group 3 (n 31) with manifestation of mucosal abnormality and clinical symptoms. In addition to the total IgE the radioallergosorbent test (RAST) was performed on sera from the infants taken before and after milk provocation. The mean total serum IgE level ranged from 288 to 560 IU/ml. In Groups 2 and 3 the prechallenge serum IgE levels were significantly higher than the postchallenge levels but in Group 1 the levels remained unchanged on challenge. A positive RAST to milk proteins was observed in five infants (7.4%), that is, one in Group 2 and four in Group 3, of 67 infants studied. In a survey of 405 consecutive paediatric-age patients admitted for a variety of symptoms, 90 were positive for RAST specific for milk proteins. Interestingly the majority of the patients positive for RAST presented with gastrointestinal ailments. The measurement of specific IgE appears not to be a useful adjunct in the diagnosis of CMPSE in Malaysian children.

Fulltext Aerogel Poly(butylene succinate) Biomaterial Substrate for RF and Microwave Applications

Habib Ullah M, Mahadi WN, Latef TA

Sci Rep, 2015;5:12868.
PMID: 26238975 DOI: 10.1038/srep12868

Polybutylene succinate (PBS) has become a potential candidate, similar to polypropylene (PP) and acrylonitrile butadiene styrene (ABS), for use as an organic plastic material due to its outstanding mechanical properties as well as high thermal deformation characteristics. A new composition of silica aerogel nanoparticles extracted from rice waste with PBS is proposed for use as a dielectric (εr = 4.5) substrate for microwave applications. A microstrip patch antenna was fabricated on the proposed dielectric substrate for multi-resonant ultra-wideband (UWB) applications. The performance characteristics of the proposed biomaterial-based antenna were investigated in a far-field measurement environment. The results indicate that the proposed biocompatible material-based antenna covered a bandwidth of 9.4 (2.3-11.7) GHz with stop bands from 5.5 GHz to 5.8 GHz and 7.0 GHz to 8.3 GHz. Peak gains of 9.82 dBi, 7.59 dBi, 8.0 dBi and 7.68 dBi were measured at resonant frequencies of 2.7 GHz, 4.6 GHz, 6.3 GHz and 9.5 GHz, respectively.

Allergen concentration in natural rubber latex

Yeang HY, Hamilton RG, Bernstein DI, Arif SA, Chow KS, Loke YH, et al.

Clin Exp Allergy, 2006 Aug;36(8):1078-86.
PMID: 16911364 DOI: 10.1111/j.1365-2222.2006.02531.x

BACKGROUND:
Hevea brasiliensis latex serum is commonly used as the in vivo and in vitro reference antigen for latex allergy diagnosis as it contains the full complement of latex allergens.

OBJECTIVE:
This study quantifies the concentrations of the significant allergens in latex serum and examines its suitability as an antigen source in latex allergy diagnosis and immunotherapy.

METHODS:
The serum phase was extracted from centrifuged latex that was repeatedly freeze-thawed or glycerinated. Quantitation of latex allergens was performed by two-site immunoenzymetric assays. The abundance of RNA transcripts of the latex allergens was estimated from the number of their clones in an Expressed Sequence Tags library.

RESULTS:
The latex allergens, Hev b 1, 2, 3, 4, 5, 6, 7 and 13, were detected in freeze-thawed and glycerinated latex serum at levels ranging from 75 (Hev b 6) to 0.06 nmol/mg total proteins (Hev b 4). Hev b 6 content in the latex was up to a thousand times higher than the other seven latex allergens, depending on source and/or preparation procedure. Allergen concentration was reflected in the abundance of mRNA transcripts. When used as the antigen, latex serum may bias the outcome of latex allergy diagnostic tests towards sensitization to Hev b 6. Tests that make use of latex serum may fail to detect latex-specific IgE reactivity in subjects who are sensitized only to allergens that are present at low concentrations.

CONCLUSION:
Latex allergy diagnostics and immunotherapy that use whole latex serum as the antigen source may not be optimal because of the marked imbalance of its constituent allergens.

Allergenic proteins of natural rubber latex

Yeang HY, Arif SA, Yusof F, Sunderasan E

Methods, 2002 May;27(1):32-45.
PMID: 12079415 DOI: 10.1016/S1046-2023(02)00049-X

As the living cytoplasm of laticiferous cells, Hevea brasiliensis latex is a rich blend of organic substances that include a mélange of proteins. A small number of these proteins have given rise to the problem of latex allergy. The salient characteristics of H. brasiliensis latex allergens that are recognized by the International Union of Immunological Societies (IUIS) are reviewed. These are the proteins associated with the rubber particles, the cytosolic C-serum proteins and the B-serum proteins that originate mainly from the lutoids. Procedures for the isolation and purification of latex allergens are discussed, from latex collection in the field to various preparative approaches adopted in the laboratory. As interest in recombinant latex allergens increases, there is a need to validate recombinant proteins to ascertain equivalence with their native counterparts when used in immunological studies, diagnostics, and immunotherapy.

Fulltext Allergens derived from shrimp

Mary Margaret, P.D.S., Jinap, S., Ahmad Faizal, A.R.

International Food Research Journal, 2015;22(5):1751-1754.
MyJurnal

Allergy caused by food is usually type 1 allergy of four types of allergic reactions. One of the most widespread allergic is those that are caused by crustacean shellfish. Crustaceans are classified among arthropods which include crab, crayfish, lobster, prawn and shrimp. Shrimp which are broadly consumed as nutritional food is one of the most important food that contribute to allergy. Thus, reducing the allergenicity of shrimp allergen will be helpful to individuals who are sensitive to shrimp and for this reason the characteristics of each allergen need to be studied. Those sensitized individuals can develop urticaria, angiodema, laryngospasm, asthma and life threatening anaphylaxis. To date, four main allergens contribute to allergic reactions. They are tropomyosin (TM), a highly conserved and heat stable myofibrillar protein of 35-38 kDa followed by arginine kinase (AK) which is also known as Pen m 2 or Lit v 2 with 40 kDa. Two other contributing allergens are sarcoplasmic calcium-binding protein (SCP) also known as Lit v 4 with 22 kDa and myosin light chain (MLC) which is also termed as Lit v 3 with 20 kDa. This mini-review will provide a better understanding of each allergen derived from shrimp which subsequently will help to reduce the allergenicity.

PMID: 27495890 MyJurnal

Hypersensitivity to stainless steel sternal sutures are an uncommon occurrence. We present a case of such a patient who developed chronic tissue overgranulation over a sternotomy wound eight weeks post-operatively. Primary suspicion was infection, a more common complication however radiological and laboratory investigation showed otherwise. Conservative management provided limited ephemeral success. After ensuring adequate sternal bone healing, the sutures and granulation tissue were eventually surgically removed without complication and the reoperated wound healed well.

PMID: 28352727 DOI: 10.1515/med-2015-0070

To use food-specific IgG antibody detection to explore its application in the allergy dermatoses. 181 patients were included from January 2014 to September 2014. Fourteen food-specific IgG antibodies were detected by ELISA. The positive rates of IgG antibody of the patient group and the healthy group were significantly different. The positive rates of IgG antibody of egg, milk, shrimp and crab took a large proportion in three groups of patients with three kinds of allergy dermatoses of urticaria, eczema and allergic dermatitis, the proportion of which was respectively 70.2%, 77.8% and 71.7%. There was mild and moderate intolerance of food in the allergic dermatitis group while there was no distribution difference of food intolerance in urticaria group and eczema group. Among urticaria and allergic dermatitis patients with positive antibody, the positive rate of children was significantly higher than that of adults while there was no significant difference between children and adults among eczema patients with positive antibody. Allergy dermatoses are closely related to food-specific IgG antibody and the allergy dermatoses patients have a high incidence rate of food intolerance; detecting IgG antibody in patients is of great significance for the diagnosis and treatment of allergy dermatoses.
