Monthly fish catch surveys were carried out from December 2015 to November 2016 in four catchment areas at Hasinarghat, Kandir-dor, Pulertol, and Barartok. In addition, questionnaire interviews and focus group discussions (FGD) were done to clarify perceptions about the Kura River fishery status. A total of 59 fish species from 22 families were documented and of which 27% were threatened. The values of diversity (H</span><span class="fontstyle2">)</span><span class="fontstyle0">, richness (D</span><span class="fontstyle2">), </span><span class="fontstyle0">and evenness </span><span class="fontstyle2">(</span><span class="fontstyle0">J’</span><span class="fontstyle2">) </span><span class="fontstyle0">were calculated at 3.599, 4.345, and 0.921 respectively. The highest catch volume was recorded 19800±7722.71 kg in November 2016 at the Kandirdor and the lowest 225±110.65 kg in March 2016 at the Barartok (</span><span class="fontstyle2">p</span><span class="fontstyle0">&lt;0.05). The upstream blockage (man-made dam) in the Kura River was identified as the main cause of fish habitat change, decrease fish biodiversity, and production of this River. Therefore, the findings of this study exposed that the conservation of fish has become urgent. In this regard, the baseline scenario of the Kura River biodiversity and threats will help to make awareness to take necessary conservation strategy as well as the need for further in-depth study.</span></p> SANZIB KUMAR BARMAN MRITYUNJOY KUNDA SABUJ KANTI MAZUMDER MD NAHIDUZZAMAN PARTHO PROTIM BARMAN SIMON KUMAR DAS Copyright (c) 2021 Malaysian Applied Biology 2021-12-31 2021-12-31 50 3 1 14 DNA PROFILE OF COMMERCIAL PINEAPPLES IN MALAYSIA BY USING SSR MARKERS https://jms.mabjournal.com/index.php/mab/article/view/2209 <p><span class="fontstyle0">Nine commercial varieties of pineapples in Malaysia (Josapine, Maspine, MD2, Sarawak, Gandul, N36, Moris, Crystal Honey and Yankee) were collected from various places in Peninsular Malaysia and analysed for cultivar identifications using nine simple sequence repeat (SSR) markers. A total of 27 alleles have been observed which ranged from 2 to 5 with an average of 3 alleles per locus. The polymorphic information content (PIC) value ranged from 0.3426 (Acom_82.8) to 0.6561 (Acom_67.2) with a mean of 0.4524 while the heterozygosity value ranged from 0.1097 (TsuAC021) to 0.8010 (TsuAC039) with a mean of 0.5481. The pairwise Nei’s genetic distances had also been calculated and the value ranged from 0.0562 (Gandul and Josapine) to 0.6383 (MD2 and Yankee) with an average value of 0.3169. The above data emphasised a moderate level of polymorphisms among the nine varieties. A dendrogram was constructed by using the unweighted pair group method with arithmetic mean (UPGMA) which showed all the nine successfully differentiated pineapple commercial varieties. A principal coordinate analysis (PCoA) was also had been generated which revealed an agreement with the dendrogram output. Therefore, these nine SSR markers can be used to identify the nine selected commercial varieties to ensure pure planting materials.</span></p> SITI NORHAYATI ISMAIL NURUL SHAMIMI ABDUL GHANI SHAHRIL AB RAZAK RABIATUL ADAWIAH ZAINAL ABIDIN MOHD NIZAM ZUBIR ROZLAILY ZAINOL Copyright (c) 2021 Malaysian Applied Biology 2021-12-31 2021-12-31 50 3 15 22 PHYTOCHEMICAL COMPOSITION AND BIOLOGICAL ACTIVITIES OF CRUDE EXTRACT FROM FLOWERS AND LEAVES OF Rhododendron arboreum Sm.

In Thailand, other than for horticultural purposes, scant literature describes the potential applications of this </span><em><span class="fontstyle0">Rhododendron </span></em><span class="fontstyle2">species. Phytochemical composition, biological activity, and cell cytotoxicity of </span><em><span class="fontstyle0">R. arboreum </span></em><span class="fontstyle2">Sm. flower petal and leaf extracts were determined. Ethanolic extracts of fresh and dried flower petals (FF and DF, respectively) and dried leaves (DL) of </span><em><span class="fontstyle0">R. arboreum </span></em><span class="fontstyle2">were prepared by maceration with 60% ethanol for 7 days. Extraction yields of both FF and DF were higher than DL (19.22, 16.76, and 8.50% for FF, DF, and DL, respectively). Preliminary qualitative phytochemical screening showed different compositions in diverse plant parts. Saponins and tannins were present in every extract, with anthraquinones detected only in flowers and terpenoids only in leaves. Total phenolic (TPC) and flavonoid contents (TFC) were highest in DL (405.21 mg gallic acid equivalent and 127.30 mg catechin equivalent per g of dry extract, respectively), followed by DF and FF. Antioxidant properties were determined using two radical scavenging assays as 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2-azinobis(3-ethyl-benzthiazoline-6-sulfonic acid (ABTS). Results indicated that all extracts exhibited better inhibitory activity against DPPH radical than ABTS radical as evidenced by lower IC</span><span class="fontstyle2">50 </span><span class="fontstyle2">range 24.65-48.15 ìg/mL for DPPH and 65.19-76.36 ìg/mL for ABTS, respectively. A positive correlation coefficient between the two antioxidant assays and TPC and TFC of </span><em><span class="fontstyle0">Rhododendron </span></em><span class="fontstyle2">extracts indicated antioxidant potential distributed in both components.

The present study investigated whether the administration of Tualang honey in the rapid eye movement (REM) sleep deprivation rat model would modulate nociceptive responses with associated changes in the thalamus. Forty-eight Sprague Dawley male rats were randomised into four groups (n=12 for each group): control group (FMC), REM sleep deprivation (REMsd), REM sleep deprivation pretreated with Tualang Honey for 1 month (REMsdH) and tank control (TC). Following sleep deprivation for 72 hours, a formalin test was conducted and pain behaviour was recorded and analysed. The rats were sacrificed, and the brains were removed for histological examination and assessment of N-methyl-D-aspartate receptor (NMDA R2) level in the thalamus. REMsdH group showed a significantly lower level of pain behaviour score and NMDA R2 compared to the REMsd group (p&lt;0.05). In addition, REMsdH also demonstrated a significantly higher number of Nissl stained neurons in comparison with the REMsd group (p&lt;0.05). Furthermore, dark neurons, suggestive of neuronal damage, were observed in the REMsd group. In conclusion, administration of Tualang honey before REM sleep deprivation modulated nociceptive responses and prevent changes in thalamic neurons and NMDA R2 level.</p> ANIS SYAHIRAH MOHD SHAFIE CHE BADARIAH ABD AZIZ LIZA NOORDIN IDRIS LONG ANANI AILA MAT ZAIN ROSFAIIZAH SIRAN Copyright (c) 2021 Malaysian Applied Biology 2021-12-31 2021-12-31 50 3 39 47 TEMPORAL AND SPATIAL VARIATIONS OF SELECTED WATER QUALITY PARAMETERS IN SERGESTID SHRIMPS’ HABITAT ALONG COASTAL WATER OF MIRI, SARAWAK, MALAYSIAN BORNEO https://jms.mabjournal.com/index.php/mab/article/view/49-56 <p><span class="fontstyle0">Evidences have shown that coastal water as habitat that support various flora and fauna as well as nursery ground which highlight the importance of water quality monitoring that act as basis for productivity of fisheries.

This krill-like shrimp, locally known as ‘bubok’, is one of the commercially important fisheries in Miri, Sarawak, Malaysian Borneo. Previous researchers had reported patchy data on the environmental factors and <em>Acetes</em> distribution in Miri-Bintulu adjacent areas. Moreover, insufficient analysis has led to the inability to conduct sustainable management strategies for </span><em><span class="fontstyle2">Acetes </span></em><span class="fontstyle0">fisheries. Therefore, this study is designed to explore the mathematical model usage to understand the interaction between selected water quality parameters and zooplankton assemblages with the </span><span class="fontstyle2"><em>Acetes</em> </span><span class="fontstyle0">population in the coastal water of Miri. Selected temporal biotic and abiotic data were collected using standard methods and later subjected to mathematical time series analysis called the Granger causality test. The results show bi-directional Granger causality between the abundance of </span><span class="fontstyle2"><em>Acetes</em> </span><span class="fontstyle0">and dissolved oxygen (DO).

The combination of these cooking methods could produce greasy and fatty products thus negatively affect health in a long term. Other cooking methods could be better alternatives to the common methods. Therefore, this study aimed to investigate the effect of six cooking methods namely boiling, steaming, air frying, deep-frying, microwaving and oven-cooking on the </span><span class="fontstyle0"><em>KL</em> </span><span class="fontstyle2">quality. The cooked samples were analysed for the moisture, fat, linear expansion, cooking yield, water holding capacity, colour, texture and sensory properties. Boiling showed the highest linear expansion (3.02%), cooking yield (104.10%) and water holding capacity (41.04%). Meanwhile, deep frying significantly reduced (</span><span class="fontstyle0">p</span><span class="fontstyle2">&lt;0.05) the moisture (39.83%) and increased the fat (6.58%) contents, exhibited harder texture (93.13N) and showed a higher yellowness value (8.23) compared to other cooking methods. No significant difference (</span><span class="fontstyle0">p</span><span class="fontstyle2">&gt;0.05) was found in other properties; however, panellists significantly (</span><span class="fontstyle0">p</span><span class="fontstyle2">&lt;0.05) preferred the crispiness and overall acceptability of the deep-fried followed by oven-cooked </span><em><span class="fontstyle0">KL</span></em><span class="fontstyle2">.

They are also responsible for a complex interaction, which is manifested in soils as self-organized systems of different sizes and functions. These invertebrates are sensitive to any changes in land management activities and soil physio-chemical properties. Therefore, the current study aims to examine the ecosystem functions of soil invertebrates from different agriculture fields and establish the relationships of soil physio-chemical properties. Soil samples were collected from four different fields: three are from the main campus, namely Universiti Putra Malaysia (Center of Environmental and Forensic Studies (CEFS), papaya and organic farm), and one is from Nilai, Negeri Sembilan. The soil physical properties, such as moisture, temperature, particle size, bulk density, and soil porosity, were recorded. Soil chemical properties (EC, pH, total C&amp;N, C/N ratio, organic matter, extractable P, Ca, Mg, K, and Na, CEC) were also determined. Pitfall traps and Berlese funnel were used as sampling methods. The invertebrates were stored in 70% ethanol and identified using soil invertebrate morphological classification, which was classified based on body size and biological functional groups. Macrofauna composition in the papaya farm was abundant from other sites at 80.44%, and ecosystem engineers comprised 39.56%. By contrast, mesofauna was abundant with 43.22% in organic farms, and litter transformers were abundant in CEFS at 54.05%. Meanwhile, microfauna was high in organic farms at 2.85%. Predatory populations were also high in Nilai farm at 49.29%. The CCA analysis showed that the physical and chemical properties of soil influence soil fauna density and diversity. The present finding concludes that the activities of ecosystem functions of soil invertebrates were considerably affected by agricultural and management activities</span></p> ABRAR S MAQTAN HISHAMUDDIN OMAR MUSKHAZLI MUSTAFA NUR AIN IZZATI MOHD ZAINUDIN Copyright (c) 2021 Malaysian Applied Biology 2021-12-31 2021-12-31 50 3 123 133 EFFICACY OF LIVE ATTENUATED FOWL ADENOVIRUS SEROTYPE 8B ISOLATE OF MALAYSIA IN SPECIFIC PATHOGEN-FREE CHICKENS https://jms.mabjournal.com/index.php/mab/article/view/1998 <p><span class="fontstyle0">Fowl adenovirus (FAdV) is the primary agent of inclusion body hepatitis (IBH) in poultry and caused serious economic impact due to high mortality and poor productivity. To date, clinical cases of IBH in chickens increases over the years in Malaysia, thus, an effective local vaccine to control the disease outbreak is in dire need. The objective of the study was to determine the efficacy of live attenuated FAdV serotype 8b isolate, UPM1137CEL35, in specific-pathogen-free chickens. Attenuated isolate UPM1137CEL35 conferred full protection against the virulent FAdV isolate, UPM11134 in the vaccinated chickens. Neither clinical signs nor mortality were recorded in all vaccinated groups. However, in the challenged unvaccinated group, chickens showed clinical signs of weakness, reduced feed consumption, and lateral recumbency at day 4 to 7 postchallenge. Additionally, the body weight was low significantly (</span><span class="fontstyle2">p</span><span class="fontstyle0">&lt;0.05) compared to the challenged vaccinated groups. Upon necropsy, the liver from the challenged unvaccinated group was pale at peripheral bilateral lobes with the presence of focal lymphoid aggregation microscopically, while, challenged vaccinated groups were normal without significant changes. All vaccinated chickens were protected from disease manifestations with antibody response compared to the challenged unvaccinated group. It was concluded that the attenuated FAdV isolate, UPM1137CEL35, has a high potential to be used as a vaccine against the FAdV serotype 8b of Malaysian isolates.</span></p> NORFITRIAH MOHAMED SOHAIMI MOHD HAIR BEJO Copyright (c) 2021 Malaysian Applied Biology 2021-12-31 2021-12-31 50 3 135 143 ELUCIDATING THE ROLE OF THE SATB1 GENE IN BREAST CANCER CARCINOGENESIS IN THE PRESENCE OR ABSENCE OF TOCOTRIENOL-RICH FRACTION: EVIDENCE FROM A SYNGENEIC MOUSE MODEL OF BREAST CANCER https://jms.mabjournal.com/index.php/mab/article/view/2087 <p><span class="fontstyle0">Tocotrienols are reported to possess anticancer activities. Recently we showed that the anticancer effects of tocotrienolrich fraction (TRF) may be through inhibition of the </span><em><span class="fontstyle2">special AT-rich sequence-binding protein 1 </span></em><span class="fontstyle0">(</span><em><span class="fontstyle2">SATB1</span></em><span class="fontstyle0">) gene in a syngeneic mouse model of breast cancer (BC). The present study aims to further explore the role of the <em>SATB1</em> gene in murine BC cells. The expression of the </span><span class="fontstyle2">SATB1 </span><span class="fontstyle0">gene in the 4T1 murine BC cells was partially knocked down (SATB1-4T1) using the short hairpin RNA (shRNA) technology and these cells were injected into the mammary pads of mice. Control groups were injected with wild-type 4T1 (WT 4T1) cells. When the tumour was palpable, half of the mice in both groups were fed daily with 1 mg TRF and received intraperitoneal injections of dendritic cells pulsed with tumour lysate (DC+TL) once a week for three weeks. The tumour incidence in mice injected with the SATB1-4T1 cells was reduced (</span><span class="fontstyle2">p</span><span class="fontstyle0">&lt;0.05) and this effect was independent of TRF supplementation. However, in mice injected with WT-4T1, there was inhibition of tumour growth (</span><span class="fontstyle2">p</span><span class="fontstyle0">&lt;0.05) only in the group fed with TRF. In addition, the expression of </span><em><span class="fontstyle2">S1004A </span></em><span class="fontstyle0">and mutant </span><em><span class="fontstyle2">P53 </span></em><span class="fontstyle0">genes were suppressed in tumours from animals that were injected with the SATB1-4T1 cells, irrespective of TRF supplementation; which was also observed in tumours from mice injected with WT 4T1 cells and fed with TRF. These findings suggest that TRF may work through the SATB1 pathway.</span></p> SITTI RAHMA ABDUL HAFID AMMU KUTTY RADHAKRISHNAN Copyright (c) 2021 Malaysian Applied Biology 2021-12-31 2021-12-31 50 3 145 161
