Abstract
BACKGROUND Kenaf seeds are underutilized kenaf plant by-products, containing essential nutrients including dietary fiber (DF), which can be potentially utilized as food ingredients. The present study aimed to evaluate the physicochemical characteristics of kenaf seed fiber fractions extracted from kenaf seed. RESULTS Defatted kenaf seed powder yielded four DF fractions: alkali-soluble hemicellulose (146.4 g kg-1 ), calcium-bound pectin (10.3 g kg-1 ) and acid-soluble pectin (25.4 g kg-1 ) made up the soluble fibre fraction, whereas cellulose (202.2 g kg-1 ) comprised the insoluble fraction. All fractions were evaluated for their physicochemical properties. The DF fractions contained glucose, mannose, xylose and arabinose, and a small amount of uronic acid (1.2-2.7 g kg-1 ). The isolated pectin fractions had a low degree of esterification (14-30%). All the isolated DF fractions had high average molecular weights ranging from 0.3 to 4.3 × 106 g mol-1 . X-ray diffractogram analysis revealed that the fractions consisted mainly of an amorphous structure with a relative crystallinity ranging from 31.6% to 44.1%. The Fourier-transform infrared spectroscopy spectrum of kenaf seed and its DF fractions showed typical absorption of polysaccharides, with the presence of hydroxyl, carboxyl, acetyl and methyl groups. Scanning electron microscopy analysis demonstrated that the raw material with the rigid structure resulted in soluble and insoluble DF fractions with more fragile and fibrous appearances, respectively. The soluble DF demonstrated greater flowability and compressibility than the insoluble fractions. CONCLUSION These findings provide novel information on the DF fractions of kenaf seeds, which could be used as a potential new DF for the food industry. © 2023 Society of Chemical Industry.

Abstract
Magnesium (Mg) has important effects on vascular system and deficiency of this cation is thought to be a risk factor for cerebrovascular atherosclerosis and complications. The study was planned to find out the association of serum magnesium level with severity of neurological disability in patient with acute ischemic stroke. This cross-sectional descriptive study was conducted in the department of Neurology and Medicine at Mymensingh Medical College & Hospital, Mymensingh from June, 2018 to October, 2019. Patients with acute ischemic stroke were evaluated following informed written consent. Diagnosis was confirmed by neuroimaging of brain. Moreover, serum magnesium assay was done for each patient. Data were collected by interview, clinical examination and laboratory investigations of patients using a case record form and analysis was carried out by using the SPSS 22.0 (IBM Inc., Armonk, NY, USA). Mean age of acute ischemic stroke patients was 63.94±13.93 years with male predominance (58.30%). Majority of the respondents (70.2%) had NIH Stroke Scale (NIHSS) score 5-15 (moderate stroke), 13.1% had score 1-5 (minor stroke), 13.1% had score15-20 (Moderate to severe stroke) and 3.6% had score 21-42 (severe stroke). Mean serum magnesium level was 1.83±0.283mg/dl. Hypomagnesaemia was present in 28(33.3%) patients and it was related with higher NIHSS scoring (p<0.05). Multiple regression showed that among the risk factors, serum magnesium level was independently associated with severity of neurological disability of the acute ischemic stroke (p<0.001). In this study, the correlation coefficient between serum magnesium level and NIHSS score was found as r= - 0.667 which showed negative relationship between serum magnesium and NIHSS score. Lower serum magnesium level is associated with the severity of neurological disability of acute ischemic stroke patient. Further case-control studies are required to validate this finding.

Abstract
Abstract Maydis leaf blight, caused by Bipolaris maydis, is an important disease of maize crop in Khyber Pakhtunkhwa (KP) Pakistan. Fifteen isolates of the pathogen, collected across KP, were studied for variability based on phenotypic and molecular markers. Significant variability among the isolates was observed when assessed using phenotypic traits such as radial growth, spore concentration, fungicide sensitivity and virulence. The isolates were classified into six culture groups based on colour, texture and margins of the colony. Conidial morphology was also variable. These were either straight or slightly curved and light to dark brown in colour. Fungicide test showed significant variation in the degree of sensitivity against Carbendazim. Isolate Bm8 exhibited maximum radial growth on carbendazim spiked plates. Conversely, isolate Bm15 showed the lowest radial growth. Variations in virulence pattern of the isolates were evident when a susceptible maize variety Azam was inoculated with spores of B. maydis. Genetic variability amongst the isolates was also estimated by RAPD as well as sequencing of ITS region. The RAPD dendrogram grouped all the isolates into two major clusters. Average genetic distance ranged from 0.6% to 100%, indicating a diverse genetic gap among the isolates. Maximum genetic distance was found between isolates Bm9 and Bm10 as well as Bm2 and Bm8. Conversely, isolates Bm13 and Bm15 were at minimum genetic distance. Phylogenetic dendrogram based on sequencing of ITS region grouped all the isolates into a single major cluster. The clusters in both the dendrogram neither correlate to the geographical distribution nor to the morphological characteristics.

Effect of Acidic Electrolysed Water and Pulsed Light Technology on the Sensory, Morphology and Bioactive Compounds of Pennywort ( Centella asiatica L.) Leaves. MOLECULES (BASEL, SWITZERLAND) 2022; 28:molecules28010311. [PMID: 36615505 PMCID: PMC9822038 DOI: 10.3390/molecules28010311] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 12/16/2022] [Accepted: 12/22/2022] [Indexed: 01/03/2023]
Abstract
Pennywort (Centella asiatica) is a herbaceous vegetable that is usually served in the form of fresh-cut vegetables and consumed raw. Fresh-cut vegetables are in high demand as they offer convenience, have fresh-like quality and are potentially great for therapeutic applications. However, it could be the cause of foodborne outbreaks. Pulsed light is known as a decontamination method for minimally processed products. The aim of this study was to determine the influence of pulsed light in combination with acidic electrolysed water on the sensory, morphological changes and bioactive components in the leaves of pennywort during storage. A combination of soaking with acidic electrolysed water (AEW) at pH 2.5 and pulsed light (PL) treatment (1.5 J/cm2) was tested on the leaves of pennywort. After treatment, these leaves were refrigerated (4 ± 1 °C) for two weeks and evaluated on the basis of sensory acceptance, the visual appearance of the epidermal cell and bioactive compounds. In terms of sensorial properties, samples treated with the combined treatment were preferred over untreated samples. The combination of AEW and PL 1.5 J/cm2 was the most preferred in terms of purchasing and consumption criteria. Observations of the epidermal cells illustrated that PL treatment kept the cell structure intact. The bioactive phytocompounds found in the leaves of pennywort are mainly from the triterpene glycosides (asiaticoside, madecassoside, asiatic acid and madecassic acid) and are efficiently preserved by the combined treatment applied. In conclusion, the combination of acidic electrolysed water and pulsed light treatment is beneficial in retaining the sensory quality and bioactive compounds in the leaves of Pennywort during storage at 4 ± 1 °C.

Abstract
Neuroendocrine tumor of the gallbladder is a rare gallbladder tumor with aggressive behavior and poor prognosis. Cholelithiasis is the most important risk factor for it. The clinical presentations of most patients are non-specific and vague abdominal pain is the most common initial symptom followed by cholecystitis, with obstructive jaundice, weight loss, ascites, pruritus or palpable mass and occasional associated endocrine manifestations. Surgery remains the main cornerstone for it. In January 2019, in the department of Hepatobiliary, Pancreatic and Liver transplant surgery in Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh, a 30-year-old female presented with incidental finding of gallbladder mass. Extended cholecystectomy was performed. Histopathology examination revealed small cell neuroectodermal tumor of the gallbladder.

Abstract
Hemosuccus pancreaticus or bleeding from the pancreatic duct into the gastrointestinal tract via the ampulla of Vater is caused by rupture of the pseudoaneurysm of a peripancreatic vessel into pancreatic duct or pancreatic pseudocyst in the context of pancreatitis or pancreatic tumour or trauma. It produces diagnostic and therapeutic dilemma due to its anatomical location and that bleeding into the duodenum is intermittent and cannot be easily diagnosed by endoscopy, often needs CE-CT and angiography. In August 2019, a 60-year-old male presented with intermittent abdominal pain, gastrointestinal bleeding and high serum lipase. Upper GIT endoscopy showed blood mixed bile coming out through ampulla, suspecting Hemosuccus pancreaticus. Contrast-enhanced computed tomography (CT) scan demonstrated pancreatic pseudo cyst with partially thrombosed splenic artery pseudoaneurysm. At laparotomy, splenic artery pseudoaneurysm was ligated along with splenectomy. Later on, the patient had no further occurrence of gastrointestinal bleeding.

Abstract
Fresh pennywort (Centella asiatica) is usually eaten raw as 'ulam' or salad-like lettuce. Unfortunately, the fresh pennywort has the potential to cause foodborne outbreaks due to pathogens present on the surface and between the leaves, as washing the pennywort using tap water alone cannot guarantee that the pathogens are eliminated. Thus, the efficacies of several sanitizing solutions, i.e., sodium chloride, sodium hypochlorite, acetic acid, acidic electrolyzed water (acidic EW), alkaline electrolyzed water (alkaline EW), and a combination of acidic EW and alkaline EW (acidic-alkaline EW), were evaluated for their potential applications as washing solutions for pennywort. Washing using acidic EW alone or in combination with alkaline EW (two-step washing) reduced the microbial count. In sensory evaluation, all sanitizer solutions were accepted by the panellists with a score greater than 5, except those washing with acetic acid. Overall, the use of acidic EW, either alone or in combination with alkaline EW, was the best treatment to decontaminate microbes while maintaining the physicochemical and sensory properties of pennywort leaves.

Abstract
The excellent health benefits of oil extracted from seeds have increased its application in foods, pharmaceutical and cosmetic industries. This trend leads to a growing research area on their by-products, oilseed meals, to minimize environmental and economic issues. Examples of these by-products are soybean, peanut, kenaf seed, hemp, sesame, and chia seed meals. It is well known that soybean meals have wide applications in food and non-food industries, while other seed meals are not well established. Most oilseed meals are rich in health beneficial compounds and are potential sources of plant protein, dietary fiber, and antioxidants. Many studies have reported on the valorization of these by-products into value-added food products such as bakery and meat products to increase their nutritional and functional properties. These efforts contribute to the sustainability, development of novel functional food and support the zero-waste concept for the environment. This review aims to provide information on the composition of selected oilseed meals from soybean, peanut, hemp, kenaf, sesame and chia seeds, their potential applications in the bakery, meat, beverage, pasta, and other food products, and to highlight the issues and challenges associated with the utilization of oilseed meals into various food products.

Abstract
Kenaf seeds are underutilized source of food with good source of dietary fiber, protein, essential oil, and phytocompounds. The objectives of this study were to determine the nutritional composition of kenaf seeds, the techno-functional properties of kenaf seeds dietary fibre (KSDF), and sensory analysis of pan bread fortified with dietary fibre that was extracted from kenaf seeds. Analyses showed that kenaf seeds are rich in dietary fibre (28.87 g/ 100 g), protein (27.07 g/ 100 g), oil (23.78 g/100 g) and mineral (5.55 g/100 g). The dietary fibre that was extracted through enzymatic hydrolysis (KSDF (EH)) exhibited significantly (p < 0.05) greater water-binding capacity (WBC), oil-binding capacity (OBC) and viscosity than non-enzymatic hydrolyzed kenaf seeds dietary fibre (KSDF (NEH)) and defatted kenaf seed meal (DKSM). Different formulations of bread were prepared by replacing 10% of wheat flour with wheat bran fibre (positive control), rice bran fibre and KSDF, with white bread unfortified with fibre as negative control. Addition of 10% KSDF to bread formulation significantly (p < 0.05) reduced bread height, volume, specific volume, water activity and firmness, and increased proofing time and bread surface colour. Results from the sensory evaluation of the bread samples also showed that KSDF bread was the most acceptable in comparison to rice bran and wheat bran fortified breads. This study shows that kenaf seed has valuable source of dietary fibre with the potential to be used as a functional ingredient in the development of functional breads.

Abstract
Purple sweet potato (PSP) is a rich source of anthocyanins, but the anthocyanin content and color can be affected by the drying method and processing condition. Response surface methodology (RSM) with a Box-Behnken design (BBD) was used to investigate the effects of citric acid (CA) concentration, steam pressure (SP) and rotation speed (DS) on the physicochemical and functional properties of drum-dried purple sweet potato powder (PSPP). The anthocyanins of the PSPP were analyzed using mass spectrometry with electrospray ionization and twelve anthocyanins were identified. The results indicated that the moisture content (4.80 ± 0.17-9.97 ± 0.03%) and water activity (0.290 ± 0.004-0.47 ± 0.001) (p < 0.05) decreased with increasing drum temperature as well as with reduced drum rotating speed. CA had a significant (p < 0.05) effect on the color and total anthocyanin content (101.83 ± 2.20-124.09 ± 2.89 mg/100 g) of the PSPP. High SP and low DS negatively affected the antioxidant properties of the PSPP. DPPH value of the PSPP ranged from 20.41 ± 0.79 to 30.79 ± 1.00 μmol TE/g. The optimal parameters were achieved at 0.59% CA, 499.8 kPa SP and 3 rpm DS.

Abstract
Dietary fiber (DF) has wide applications, especially in the food and pharmaceutical industries due to its health-promoting effects and potential techno-functional properties in developing functional food products. There is a growing interest in studies related to DF; nevertheless, there is less focus on the fractionation and characterization of DF. The characteristics of DF fractions explain their functionality in food products and provide clues to their physiological effects in food and pharmaceutical industrial applications. The review focuses on a brief introduction to DF and methods for its fractionation. It discusses the characterization of DF in terms of structural, physicochemical and rheological properties. The potential sources of DF from selected defatted oilseeds for future studies are highlighted.

Abstract
BACKGROUND 'Cempedak' (Artocarpus integer) is an aromatic fruit which is similar to jackfruit. Although it is rich in vitamin A and is consumed fresh, the fruit has a short shelf life. Hence, it can be converted through a spray-drying process, to form powder, which is more stable. Powder flow properties are important when considering storage, while its reconstitution characteristics are critical for the consumer to make juice from the product. METHODS The parameters of spray-dried 'cempedak' fruit powder under study include inlet air temperature (140-180°C) and maltodextrin (DE 10) concentrations (5-15% w/w). Response surface methodology involving 14 runs was used to assess the effects of inlet temperature and maltodextrin on the powder flow properties and reconstitution properties of the spray-dried 'cempedak' powder. RESULTS Out of the tested responses, only bulk density, change in cake height ratio, and water solubility index had a high coefficient of determination value. Inlet air temperature was found to be the main parameter to affect the bulk density, caking and water solubility index, when compared to maltodextrin concentration. By setting minimization of caking and maximization of water solubility index as the main determinants, the optimal parameters of 160°C inlet temperature and 15% (w/w) maltodextrin DE10 were generated, with a desirability of 0.697. CONCLUSIONS The powder produced under optimal conditions (160°C and 15% w/w maltodextrin) had a low bulk density (480.01 kg/m3), low caking properties (0.17 change in cake height ratio), and a high solubility index (88.69). This indicates that the powder is stable to be stored (without caking) and will have good reconstitution when added to water.

Abstract
Vitamin A deficiency is common in many countries where rice is the staple food. Food fortification is an important strategy to address this problem. As rice noodle is the second principal form of rice products widely consumed in Asia, rice noodles could be a potential vehicle for fortification of vitamin A. In this study, rice noodles were prepared from 0, 300, 600, 1,050, and 1,500 μg of vitamin A per 100 g of rice flour. Samples were analyzed for quality, sensory evaluation, and enhancement of vitamin A intakes. Increasing level of vitamin A fortification did not influence quality and sensory properties of the rice noodles, except for the ash content, color, and appearance of the noodles. Rice noodle that was fortified with the highest level of vitamin A was found to be the darkest in color. However, this sample received scores higher than 6 (like slightly) for appearance. Furthermore, sample fortified with the highest level of vitamin A produced rice noodles with the highest level of vitamin A retention suggesting that noodles were good vehicle for vitamin A fortification. Fortification of rice flour with 1,500 μg of vitamin A produced rice noodles with 24.88% of the RDI for vitamin A per serving and provided an effective means of enhancing vitamin A intake.

Abstract
Hydatid disease is one of the diseases that have been discovered in the ancient times. Liver and lung are the most commonly affected organs, though it can involve any organs. Hydatid disease involving both the liver and the lung is reported about 10% of the cases. Here we report a case of 34 year old male presented with upper abdominal pain and intermittent fever for 3 months admitted in October 2016. His chest radiograph and computed tomography scan revealed large cystic lesion at right lung and another similar large lesion in the right lobe of liver. Echinococcus antibody was found positive. We treated him surgically. Histopathology reports confirmed concomitant hydatid cyst of both the lung and the liver.

Kenaf (Hibiscus cannabinus L.) Seed and its Potential Food Applications: A Review. J Food Sci 2019; 84:2015-2023. [PMID: 31364175 DOI: 10.1111/1750-3841.14714] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2019] [Revised: 05/19/2019] [Accepted: 06/29/2019] [Indexed: 11/29/2022]
Abstract
Kenaf belongs to the family Malvaceae noted for their economic and horticultural importance. Kenaf seed is a valuable component of kenaf plant. For several years, it has been primarily used as a cordage crop and secondarily as a livestock feed. The potential for using kenaf seeds as a source of food-based products has not been fully exploited. Consumers are becoming more interested in naturally healthy plant-based food products. Kenaf seed, the future crop with a rich source of essential nutrients and an excellent source of phytocompounds, might serve suitable roles in the production of value-added plant-based foods. At present kenaf seed and its value-added components have not been effectively utilized for both their nutritional and functional properties as either ingredient or major constituent of food products. This review focuses on the possible food applications of kenaf seed and its value-added components based on their nutritional composition and functional properties available in literature, with the purpose of providing an overview on the possible food applications of this underutilized seed. The review focuses on a brief introduction on kenaf plant, nutritional function, lipids and proteins composition and food applications of the seed. The review elaborately discusses the seed in terms of; bioactive components, antioxidants enrichment of wheat bread, antimicrobial agents, as edible flour, as edible oil and a source of protein in food system. The review closes with discussion on other possible food applications of kenaf seed. The need for food scientists and technologists to exploit this natural agricultural product as a value-added food ingredient is of great significance and is emphasized.

Abstract
Introduction: Rambutan seed is considered a waste by-product of fruit processing. The seed waste is usually discarded or disposed in a large amount without an economic value which has become an issue that needs to be solved. However, the seed contains a considerable amount of crude fat. Aim: the purpose of this study was to characterize the physicochemical properties of oil of the seeds of three varieties of Malaysian rambutan fruit (R4, R7 and Serjan) for potential application. Materials and methods: In this study, colour, refractive index, viscosity, free fatty acid content, peroxide value, p-anisidine value, iodine value, saponification value, unsaponifiable matter, fatty acid composition, thermal behaviour, melting point, and solid fat content of rambutan seed oil from three varieties were used to characterise physicochemical properties of rambutan seed oil. Results: No significant differences (p > 0.05) were observed for free fatty acid content, peroxide value, p-anisidine value, saponification value, unsaponifiable matter, colour, viscosity and refractive index among three varieties. There are significant differences (p < 0.05) in the iodine value and melting point among the rambutan seed oil of three varieties. Varieties R7 and R4 seed had the highest (37.62 ± 0.10 %) and lowest (34.25 ± 0.07 %) crude fat content, respectively. Oleic (37.75-40.58 %) and arachidic (35.24-36.89 %) acids were the major fatty acids in the oil. Both melting and crystallization curves showed that the oil exhibited three distinct peaks. The complete melting and crystallization onset temperatures of the oil were 24.76–26.57°C and 21.19–22.79°C, respectively.Conclusions: This study reveals that the rambutan seed oil has potential to be used in various sectors of food industry. Therefore, rambutan seed can be fully utilized and, subsequently, the amount of waste can be minimized.

Abstract
"Porcelain gallbladder" term has been used to highlight the blue staining and fragile consistency of the gallbladder wall at surgery. Some authorities avoid these terms and alternately call all calcified gallbladders "porcelain gallbladders". It is a morphological deviation of chronic cholecystitis. Inflammatory scarring of the wall combined with dystrophic calcification inside the wall transforms the gallbladder into a porcelain-like container. In porcelain gallbladder patients are usually asymptomatic and the condition is usually noted incidentally on plain abdominal radiographs, sonograms, or computed tomography (CT) images. Porcelain gallbladder is a rare condition; recognizing the clinical and imaging characteristics of the disease is important because of the high frequency (22%) of adenocarcinoma in porcelain gallbladder. Operation should not be delayed even if the patient is asymptomatic, because the incidence of carcinoma in porcelain gallbladder is extremely high. Here we present a case of 45 years old lady with porcelain gallbladder who was initially diagnosed as a case of carcinoma gallbladder at Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh on 5th August 2017. But she was found to have a benign gallbladder after cholecystectomy.

Abstract
Solid pseudopapillary tumors (SPT) of the pancreas are rare neoplasms of the pancreas accounting for only 1-2% of all pancreatic neoplasms, often detected initially on imaging. Its histogenesis is still uncertain and it has a low-grade malignant potential but excellent post-surgical curative rates and rare metastasis. Pathological and/or cytological evaluation still remains the gold standard in reaching a definitive diagnosis. It occurs most commonly in young females. We report a case of solid pseudopapillary tumor in the head of the pancreas in a 20 years old female admitted in Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh on 5th December 2015. Whipple's operation was done as a definitive treatment.

Abstract
Pulsed-UV is an emerging innovation in non-thermal processing and is scarcely explored. This study introduces a combined treatment of microwave and pulsed-UV to reduce the microbial load in yellow alkaline noodle (YAN), a popular staple food among South East Asians that is easily perishable, without jeopardising its textural qualities. Results indicated that the combination of 5 s microwave (power = 900 W; frequency = 2450 MHz) and 3.5 J/cm2 pulsed-UV significantly reduced aerobic plate count and spore forming bacteria, from 637.5 to 50 CFU/g and 1500 to 100 CFU/g, respectively. In terms of textural properties, even though significant changes were detected in hardness and springiness for treated YAN kept at ambient storage as compared to control, the alterations were not prominent. Based on these observations, it is concluded that a combined treatment of microwave and pulsed-UV successfully improved the shelf life of YAN at ambient storage by 50%, from 1.0 day (control) to 1.5 days (treated sample) and by 140%, from 2.0 to 4.8 weeks at chilled storage. Current study proves the potential of microwave + pulsed-UV, a "green" hurdle treatment, to extend the shelf life of preservative-free YAN without causing major undesirable textural alterations on the noodle.

Abstract
Mangifera odorata fruit, the hybrid forms between M. indica (mango) and M. foetida (bacang), has been shown to exhibit potential antioxidant activity, and the fruit waste could demonstrate functional and nutritional potential. In the present study, the nutritional composition (proximate, sugars, vitamins and minerals analyses), the anti-diabetic activities and phytochemical profile of M. odorata peel and seed kernel were investigated for the first time. The results indicated that seed kernel rich in fat, protein, carbohydrate, and ash while peel contained significantly greater amount of fiber, minerals, β-Carotene and ascorbic acid compared to seed kernel. The samples were then extracted using different solvents (acetone, ethanol, methanol at 60%, v/v and pure deionized water) and their anti-diabetic activities (α-amylase and α-glucosidase inhibition assay) were determined. Seed kernel had the lowest IC50 values for α-amylase and α-glucosidase inhibition assay in 60% ethanol and 60% acetone, respectively. Due to the toxic effect and high volatility of acetone, the ethanolic extracts of samples were further analyses for their phytochemical profile using high performance liquid chromatography-mass spectrometry (LC-MS) and ultra-high-performance liquid chromatography electrospray ionization orbitrap tandem mass spectrometry (UHPLC-ESI-Orbitrap-MS/MS). The most abundant compounds identified were phenolic acid, ellagic acid, and flavonoid. These findings suggest that M. odorata fruit wastes, especially the seed kernel possesses promising ability to be used as functional ingredient in the food industry.

Abstract
A novel way to fully utilize rambutan fruit and seed is to ferment peeled fruits followed by drying and roasting, and use the seeds to produce seed powder similar to that of cocoa powder. Hence, the objective of this study was to optimize the roasting time and temperature of rambutan fruit post-fermentation and drying, and to produce a cocoa-like powder product from the seeds. Parameters monitored during roasting were colour and total phenolic content, while seed powder obtained using optimized roasting conditions was analyzed for its physicochemical properties and toxicity. The latter was examined using the brine shrimp lethality assay. Results showed that the roasted seed powder possessed colour and key volatile compounds similar to that of cocoa powder. Besides, the brine shrimp lethality assay indicated that the roasted seed powder was non-toxic. Thus, the fruit, including its seed could be fully utilized and subsequently, wastage could be reduced.

It was prospective observational study done in the EPI corner of Paediatric OPD of Dhaka National Medical College & Hospital (DNMCH), Dhaka from July 2015 to July 2016. Sixty (60) children ranging from 9 months to 2 years of age, who received pentavalent vaccination (Hepatitis B + DPT + Hib) according to EPI schedule, were included. The testing for anti-HBs titres were conducted in the Department of Virology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. Out of 60 children, 9(15%) had anti-HBs titres <10 IU/L (non-protected) while 51(85%) had anti-HBs titres >10 IU/L (protected). Twenty seven (27) were male and of them 21(77.8%) protective and 6(22.2%) non-protective. Thirty three (33) were female, out of them 30(90.9%) protective while 3(9.1%) non-protective. The difference was not significant between male and female (p=0.156). Fifty (50) children received vaccination by EPI (Government) (pentavalent) out of which 9(18%) non-protective and 41(82%) protective level. However, 10 children received privately Hepatitis B vaccination of which all developed protective level. The difference was not significant between Government (EPI) and privately vaccine (p=0.145). Most of the children showed positive immune response after pentavalent vaccination.
