Objective: To investigate phenolics, fatty acids composition and biological activities of various extracts and fractions of Malaysian Aaptos aaptos. Methods: Fatty acid methyl ester was analyzed by gas chromatography-flame ionization detector. Antioxidant activity was determined using 2,2-diphenyl-picrylhydrazyl radical scavenging assay and total phenolics content by Folin-Ciocalteu procedure. Vero cells viability was evaluated using methyl thiazole tetrazolium and the inactivation of herpes simplex virus type 1 by neutral red uptake assay. p-Hydroxybenzamide isolated by column chromatography was characterized by utilizing nuclear magnetic resonance spectroscopy and electron impact mass spectrometry. Results:The chloroform, ethyl acetate and methanol extracts of Aaptos aaptos produced higher portions of straight-chain saturated fatty acid, while hexane extract mainly consisted of unsaturated fatty acid. The five majors of fatty acid methyl ester were identified as behenic acid, cis-10-heptadecenoic acid and cis-10-pentadecenoic acids, palmitic acid and tricosanoic acid. In addition, among all organic extracts, chloroform extract inactivated herpes simplex virus type 1 while exhibited weak cytotoxic activity against normal Vero cells and also exhibited strong cytotoxic activity on HL-60, MCF-7, K562, CEM-SS and WEHI-3B cells. A phenolic compound, p-hydroxybenzamide was also isolated from the sponge. Conclusions: Aaptos aaptos could be a source to derive the potential antiviral and anticancer agents. However, further studies are needed to determine the mechanism involved in the process.

Castleman and Towne described a disease presenting as a mediastinal mass resembling thymoma. It is also known as "giant lymph node hyperplasia", "lymph node hamartoma", "angiofollicular mediastinal lymph node hyperplasia", and "angiomatous lymphoid hyperplasia". The pathogenesis is unknown, but the bulk of evidence points toward faulty immune regulation, resulting in excessive B-lymphocyte and plasma-cell proliferation in lymphatic tissue. In addition to the mediastinal presentation, extrathoracic involvement in the neck, axilla, mesentery, pelvis, pancreas, adrenal gland, and retroperitoneum also have been described. There are 2 major pathologic variations of Castleman disease: (1) hyaline-vascular variant, the most frequent, characterized by small hyaline-vascular follicles and capillary proliferation; and (2) the plasma-cell variant, in which large lymphoid follicles are separated by sheets of plasma cells. The hyaline-vascular cases usually are largely asymptomatic, whereas the less common plasma-cell variant may present with fever, anemia, weight loss, and night sweats, along with polyclonal hypergamma-globulinemia. Castleman disease is a rare lymphoproliferative disorders. Few cases have been described world widely. In this article we reviewed the classification, pathogenesis, pathology, radiological features and up to date treatment with special emphasis on the role of viral stimulation, recent therapeutic modalities and the HIV-associated disease.

Current treatment for inflammatory bowel disease (IBD) includes the application of anti-inflammatory agents for the induction and remission of IBD. However, prolonged use of anti-inflammatory agents can exert adverse effects on patients. Recently, formulated dietary approach in treating IBD patients is utilized to improve clinical activity scores. An alteration of gastrointestinal microbiota through dietary therapy was found to reduce IBD and is recognized as a promising therapeutic strategy for IBD. One of the recommended formulated diets is an anti-inflammatory diet (AID) that restricts the intake of carbohydrates with modified fatty acids. This diet also contains probiotics and prebiotics that can promote balanced intestinal microbiota composition. However, scientific evidences are limited to support this specific dietary regime in maintaining the remission and prevention relapse of IBD. Therefore, this review aimed to summarize available data from various studies to evaluate the AID diet effectiveness which will be useful for clinicians to manage their IBD patients by application of improved dietary therapy.

Previous studies explain the time course of withdrawal symptoms among smokers pre and post quit attempt, either withor without the help of medication. Studies showed that male Muslim smokers could quit smoking during Ramadan sincefasting relate to the changes in psychosomatic, daily activities and nicotine withdrawal symptoms. This study aimed toinvestigate the time course of withdrawal symptoms among smokers who used nicotine patch to quit smoking duringfasting in Ramadan. A total of 40 eligible Muslim males who tried to quit smoking was selected and provided with smokingcessation counseling for the duration of 8 to 10 weeks while on nicotine patch. Participants level of withdrawal symptomswas recorded by using nine items of Minnesota Nicotine Withdrawal Scale over a period of 60 days. Participant’s carbonmonoxide reading and body weight were measured within six months including pre and post-Ramadan fasting. Over fourweeks of the fasting month, the measured withdrawal symptoms such as urge to smoke (P ≤ 0.001), depressed mood (P≤ 0.001), irritability/frustration or anger (P ≤ 0.05), anxiety (P ≤ 0.05), difficulty concentrating(P ≤ 0.001), restlessness(P ≤ 0.001), difficulty going to sleep (P ≤ 0.001) and impatient (P ≤ 0.05) significantly decreased except appetite by theend of week 4. Time course analyses demonstrated that all outcome measures showed good effects during cessation infasting month. The point prevalence abstinence at first month of quitting was 67.5% which is higher in fasting month.This has shown positive clinical implications in managing smoking cessation program during Ramadan with the aid ofnicotine patch.

Background/Aims:
Ulcerative colitis (UC) is a chronic, relapsing and remitting inflammation of the gastrointestinal tract. Little is known about the link between dietary intake, food avoidance, and beliefs among UC patients of different disease severity. Therefore, this study aimed to assess the dietary intake, food avoidance, and beliefs among active and inactive UC patients.
Methods:
A cross-sectional study was conducted among UC patients from a tertiary medical center in Kuala Lumpur, Malaysia. Demographic, anthropometric, dietary intake, food avoidance and beliefs were assessed. Disease activity of UC patients was evaluated using the Powell Tuck Index.
Results:
UC patients were recruited (64.1% inactive UC and 35.9% active UC). As compared to inactive UC patients, active UC patients were likely to lose weight (75.0% vs. 0%), possess certain food beliefs (95.7% vs. 39.0%), and frequently practiced dietary avoidance (95.7% vs. 43.9%). The dietary intake among inactive UC patients was higher than active UC patients. However, neither of them met the standard nutrients recommendation for protein, calcium, iron, folate, zinc, vitamin D, vitamin B12, and vitamin E.
Conclusions
Active UC patients had poorer dietary intake, were more prone to practicing food avoidance and exhibited certain food beliefs as compared to inactive UC patients. Both macro- and micronutrients intakes were inadequate regardless of patient’s disease status. These findings emphasized the importance for patients to be provided with the nutrition-related knowledge as part of strategies to avoid nutritional inadequacies.

Wild cotton species can contribute a valuable gene pool for agronomically desirable cultivated tetraploid cultivars. In order to exploit diploid cotton a regeneration system is required to achieve transformation based goals. The present studies aimed at optimizing the conditions for regeneration of local varieties as well as wild species of cotton. Different callus induction media were tested with varying concentrations of hormones in which sucrose was used as nutritional source. Different explants (hypocotyls, cotyledon, root) were used to check the regeneration of both local cotton plants and wild relatives using T & G medium, BAP medium, CIM medium, EMMS medium, and cell suspension medium. Different stages of embryogenicity such as early torpedo stage, late torpedo stage, heart stage, globular stage and cotyledonary stage were observed in wild relatives of cotton. The results of this study pave the way for establishing future transformation methods.

The circle of Willis (COW) refers to the anastomotic arterial network found on the brain base, tasked with provision of collateral circulation aimed at prevention of ischemia. The COW is of immense clinical importance especially with regard to the assessment of neurovascular diseases. Individuals portray significant variations in the COW’s anatomical configuration. The present study seeks to evaluate the existing anatomical variations of the COW and within the anterior and posterior segments of the COW. Thus, the study seeks to evaluate the different anatomical variations of the COW and its segments and components within the study population. To attain the set objectives, the present study has utilized the angiographic images for studying the COW variants in patients who underwent cerebral angiography during assessment of different types of cerebral anomalies and conditions. Therefore, this study used conventional angiography as an important tool in the evaluation of the different variations in the COW, and is most appropriate for evaluation of smaller anatomical variations owing to its perfect spatial resolution and portrayal of COW anatomy. The study findings indicated the existence between age and sex, and anatomical variations of the COW, particularly with regard to diameters of COW components like basilar artery (BA), P1, and internal carotid arterys (ICAs). Males had bigger BA, P1 and ICA diameters than females, while individuals aged below 40 years had bigger BA, A1, posterior communicating artery, and ICA diameters than those aged above 40 years.
