Effects of the consumption of algal biomass versus protein concentrate on postprandial satiety and metabolism

Algae are promising sources of nutritious and sustainable protein, but little is known about their metabolic health impact and acceptability as meal ingredients. This acute, randomized, controlled, five-way crossover trial compared whole algal biomasses and their corresponding protein concentrates to soy protein concentrate in terms of palatability, appetite, satiety, and metabolic response. Nineteen healthy Chinese males (21–50 years, 18.5–25.0 kg/m2) consumed noodle meals supplemented with 10 g of nori biomass/protein concentrate (NB/NC), Chlorella vulgaris biomass/protein concentrate (CB/CC) or soy protein concentrate control (CON) in randomized order. At regular intervals, blood samples were collected to measure biochemical markers, while gastrointestinal tolerance, palatability, and appetite were assessed using questionnaires and visual analog scales (VAS). Results indicated that algae-enriched meals were well-tolerated and comparable to soy in both visual appeal and smell, with NB and CC outperforming soy in aftertaste (p < 0.05). There were no significant differences between treatments in glucose, insulin, C-peptide, appetite/satiety, plasma ghrelin, and GLP-1. However, exploratory analysis of serum triglycerides revealed significant time × treatment effects (p < 0.004) and differences in incremental area under the curve (iAUC0–120 p = 0.0249). Our findings reveal that algal biomasses and protein concentrates are as comparable to soy protein concentrate in palatability, satiety, and metabolic outcomes, highlighting their potential as practical, sustainable, and nutritious ingredients.fals

Effect of drought on physiology and yield contributing characters of sunflower

The present study was conducted during 1995 to April 1996 at Bangladesh Agricultural University, Mymensingh to investigate the effect of drought stress at various levels with a view to studying the physiological characters of sunflower associated with yield under drought condition. Two varieties ( Kironi and Hysan-55) and five drought cycles were i) Daily watering, ii) 1 day without water, iii) 2 days without water, iv) 3 days without water, and v) 4 days without water imposed in the study. As a whole, drought treatment reduced the yield and yield contributing characters of sunflower. In most cases, the rate of reduction was higher in plants that received 4 days drought cycle followed by 3 days. The minimum reduction was observed in plants that received 1 and 2 days drought cycle. The growth parameters (CGR, RGR, NAR, and LAI) were reduced under drought treatments. Similar trend was followed in case of CSI values and RWC of the leaves. The rate of reduction for most of characters was higher in Hysan-55 than that of Kironi. Thus, the variety Kironi was found better than Hysan-55 in respect of physiological adaptation associated with yield under drought condition.

Performance of Mango Gerplasm in Patuakhali Condition

A study was conducted for four consecutive years from 2014 to 2917 at the Regional Horticultural Research Station (RHRS), Bangladesh Agricultural Research Institute (BARI), Lebukhali, Patuakhali. Six mango varieties, viz. BARI Aam-1, BARI Aam-2, BARI Aam-3, BARI Aam-4, BARI Aam-5, BARI Aam-8 developed by BARI and six popular cultivars Khirshapat, Langra, Mallika, Gopalbhog, Fazli and Pahutan were evaluation for their performance. The germplasm were planted in 2010. All the cultivars bloomed in 1st to 3rd week of February. Harvesting time ranged from 2nd week of May to 1st week of July and Gopalbhog and BARI Aam-4 were earlier while Fazli was late season cultivar. In the last year of study (2017), maximum number of fruits per plant was recorded 259 in BARI Aam-3 and minimum 11 in BARI Aam-1. Individual maximum fruit weight was 663.09g in BARI Aam-4 in 2016. Average, individual fruit weight ranged from 553.92 to 183.13g where Fazli was the maximum followed by 465.94g in BARI Aam-4. Minimum individual fruit weight was measured in BARI Aam-3. Total Soluble Solids percent (TSS%) ranged from 16.83 to 21 66% and BARI Aam-3 was maximum and BARI Aam- 2 was minimum. Number of fruits per plant, individual fruit and sweetness (TSS%) of variety/and cultivar fluctuated in different year although the trend of results in the succeeding years was consistent.&#x0D; Bangladesh J.

Pretreatment of Used Cooking Oil for the Preparation of Biodiesel Using Heterogeneous Catalysis

Used cooking oil (UCO) offers a number of benefits for the production of biodiesel because it is a waste material and relatively cheap; however UCOs contain free fatty acids (FFAs) which need to be removed. Esterification can be used to convert the FFAs to biodiesel, and this work has compared two types of heterogeneous catalyst for esterification. An immobilized enzyme, Novozyme 435, was investigated because it has been shown to give a high conversion of FFAs and it has been compared to an ion-exchange resin, Purolite D5081, which was developed for the esterification of UCO for the production of biodiesel. It was found that a conversion of 94% was achieved using Purolite D5081 compared to 90% conversion with Novozyme 435.UK Colloids 2011 - International Colloid and Surface Science Symposium, Jul 04-06, 2011, London, Englan

PATHOLOGICAL INVESTIGATION OF LIVER FLUKE INFECTION OF SLAUGHTERED BLACK BENGAL GOAT IN A SELECTED AREA OF BANGLADESH

This study was conducted in Sylhet district of Bangladesh to investigate the pathological effect of liver fluke in Black Bengal goats of different age groups, sex and in seasons. In this study, livers of male and female goats were collected randomly from slaughter house during a period of 1 (one) year (November, 2007 to October, 2008). A total of 325 Black Bengal goat livers were examined, of which 70 livers were found infected with Fasciola gigantica. The common histopathological changes found in this study were the migratory tract with lymphocytic infiltration, atrophy, necrosis and fatty changes in the liver. The study revealed that age of the animal has significant effect on Fascioliasis in goats. Significantly (P&lt;0.01) highest infection rate was found in 2-2.5 years old animals (50%). The sex of the animal was also found as important determinants for Fascioliasis. In this study out of 219 male goat livers 30 (13.70%) were infected with Fasciola. On the other hand, out of 106 female goat livers, 40 (37.73%) were found positive with Fascioliasis. The data of origin of animals also collected which was not statistically significant. DOI = 10.3329/bjvm.v8i1.7717 Bangl. J. Vet. Med. (2010). 8(1): 35-40</jats:p
