Enhancement of BDNF Concentration and Restoration of the Hypothalamic-Pituitary-Adrenal Axis Accompany Reduced Depressive-Like Behaviour in Stressed Ovariectomised Rats Treated with Either Tualang Honey or Estrogen
A possible interaction between glucocorticoids and estrogen-induced increases in brain-derived-neurotrophic factor (BDNF)
expression in enhancing depressive-like behaviour has been documented. Here we evaluated the effects of Tualang honey, a
phytoestrogen, and 1
Molecular Mechanisms of Peritoneal Dialysis–Induced Microvascular Vasodilation
Peritoneal dialysis (PD) solutions dilate microvessels
by undefined mechanisms. This vasodilation
directly affects ultrafiltration and solute exchange
during a PD dwell and is thought to account for the
variable mass transfer area coefficient for small
solutes during a glucose-based hypertonic dwell. We
hypothesized that PD-mediated vasodilation occurs
by endothelium-dependent mechanisms that involve
endothelium energy-dependent K+ channels (KATP),
adenosine A1 receptor activation, and NO release.
We used intravital videomicroscopy to study 3
levels of microvessels (A1 inflow arterioles about
100 μm diameter to pre-capillary A3 arterioles 10 –
15 μm diameter) in the terminal ileum of anesthetized
rats under control conditions in vivo in a tissue
bath. Ileum was bathed with hypertonic mannitol or
2.5% glucose-based PD solution (Delflex: Fresenius
Medical Care North America, Waltham, MA, U.S.A.)
with or without topical application of individual or
combined specific inhibitors of the endotheliumdependent
dilation pathways: NO (L-NMMA),
prostaglandin I2 (mefenamic acid), endothelium hyperpolarizing
factor (glibenclamide), and adenosine
A1 receptor antagonist (DPCPX).
The mannitol and PD solutions induced rapid and
sustained peritoneal vasodilation whose magnitude
depended on microvascular level and osmotic solute.
Combined inhibition of endothelium-dependent
dilation pathways completely abolished the mannitolinduced
hyperosmolality-mediated dilation at all
microvascular levels, but selectively eliminated the PD
solution–mediated A3 dilation. The KATP and adenosine
receptor antagonists, individually or combined,
remarkably attenuated dilation in the smaller pre-capillary
arterioles; NO inhibition, alone or combined with
KATP and adenosine receptor antagonists, eliminated
the PD solution–induced dilation. The cyclooxygenase
pathway is not involved in PD-induced dilation.
Solutions for PD dilate the visceral peritoneal
microvasculature by endothelium-dependent
mechanisms, primarily the NO pathway. Adenosine
receptor–activated NO release and KATP channelmediated
endothelium hyperpolarization significantly
contribute to vasodilation in the smaller peritoneal
pre-capillary arterioles.Qatar National Research Fund NPRP 09-268-3-06
Protective Effects of Tualang Honey against Oxidative Stress and Anxiety-Like Behaviour in Stressed Ovariectomized Rats
he present study aims to evaluate the antioxidant and anxiolytic-like efect of Tualang honey in stressed ovariectomized (OVX)
rats.he animals were divided into; (i) nonstressed sham-operated control rats, (ii) sham-operated control rats exposed to stress,
(iii) nonstressed OVX rats, (iv) OVX rats exposed to stress, (v) OVX rats exposed to stress and treated with 17 �-oestradiol
(E2) (20 �g daily, sc), and (vi) OVX rats exposed to stress and treated with Tualang honey (0.2 g/kg body weight, orally). he
open ield test was used to evaluate the anxiety-like behaviour and ELISA kits were used to measure oxidant/antioxidant status
of the brain homogenates. he result showed that anxiety-like behavior was signiicantly increased in stressed OVX compared
to other groups, and administering either E2 or Tualang honey signiicantly decreased anxiety-like behaviour in stressed OVX
rats.he levels of malondialdehyde (MDA) and protein carbonyl (PCO) were signiicantly decreased while the levels/activities of
superoxide dismutase (SOD), glutathione S-transferases (GST), glutathione peroxidase (GPx), and glutathione reductase (GR)
were signiicantly increased in the brain homogenates of treated stressed OVX groups compared to untreated stressed OVX.
In conclusion, Tualang honey has protective efects against brain oxidative stress and may be useful alternative anxiolytic agent
especially for postmenopausal women
The Potential Role of Melatonin on Memory Function: Lessons from Rodent Studies
Pineal melatonin biosynthesis is regulated
by the circadian clock located in the suprachiasmatic
nucleus of the hypothalamus. Melatonin has been
found to modulate the learning and memory process
in human as well as in animals. Endogenous melatonin
modulates the process of newly acquired information
into long-term memory, while melatonin
treatment has been found to reduce memory deficits
in elderly people and in various animal models.
However, the mechanisms mediating the enhancing
effect of melatonin on memory remain elusive. This
review intends to explore the possible mechanisms
by looking at previous data on the effects of melatonin
treatment on memory performance in rodents

Family Addressing System in Malay and Arab Languages: An Analysis of Sociolinguistic Clash
This study is a first attempt to comparatively study the addressing system in Malay and Arabic societies, which is an important element in communicating and interacting. This analysis uses lexicological and sociolinguistic approaches. The study found that the family addressing system in Arabic is viewed as more complicated and complex than the address forms used within the Malay society. This will cause difficulty and confusion in determining the appropriate meaning match for the terms. As a result, translators and anyone else involved in the process of moving the meaning of a word between Malay and Arabic should be cautious and always refer to the term’s meaning before assigning a match so that the receiver or reader of the translation do not become confused
Assessing knowledge, attitude, practice towards type II diabetes mellitus and their blood glucose level among public in selected areas of Bachok District, Kelantan
Diabetes is a major health problem in Malaysia particularly in Kelantan state. This cross-sectional study was designed to
determine the knowledge, attitude and perceive practice towards type II diabetes among the public residants of Kelantan in
relation towards their blood glucose level. About 68 respondents aged from 18 to 59 years old, were approached personally
to participate in this study. Data collection was done through face-to-face interview using a questionnaire consisted of four
sections; knowledge, attitude, and perceive practice (KAP) questionnaire including recent fasting blood glucose (FBG) readings.
The results showed that most of the respondents had a moderate level of knowledge (54.4%, n=37), positive attitude (72%,
n=49), and good perceive practice level (51.5%, n=35) towards diabetes mellitus. There was no significant relationship between
knowledge, attitude, and perceive practice level towards diabetes mellitus at p<0.05. KAP level towards diabetes mellitus
showed no significant relationship with blood glucose level at p<0.05. Findings indicate that most respondents had normal
BMI (18.5 – 24.9) (64.7%, n=44) and normal FBG reading (< 6.1 mmol/L) (92.6%, n=63). As conclusion, respondents
with higher educational level were more likely to have a higher level of knowledge about diabetes mellitus; however, this did
not influence attitude, perceive practice and fasting blood glucose of respondents
Systematic review of early English literacy in ELL children : what do we know from a decade of research
Early literacy is an integral aspect of young children’s learning. This review synthesizes existing empirical
research evidence from the past decade, focusing on ELL children’s (aged 4 to 6 years) early English language
literacy learning and the prevailing trends in the published literature. They were sourced mainly from three
prominent databases. Manual selection of highly-cited studies was used as a complementary technique.
Systematic exclusion and inclusion were performed and yielded 31 credible studies. The results report on
researchers’ theorizing of early English literacy, dimensions of the body of knowledge, and research
methodologies. The predictors and outcomes were examined within the lens of theoretical framework. To identify
the emerging trends, the studies were analysed qualitatively. The findings were discussed in light of three main
trends: (i) the apparent needs for an early English literacy model which captures both the concept of early literacy
acquisition and second language learning, (ii) future research to acknowledge the multifaceted phenomenon of
early literacy acquisition by employing nested research approach in a cross-discipline scope of research, and
(iii) multiple ecological factors as important sources of individual differences. Despite the strength of the review
approach to the past study identification, there are several limitations that should be considered. Among others,
the representation of the children population in the selected studies which befalls heavily on certain geographical
regions could cause bias in the coverage of knowledge
Assessment of diet quality and its association with nutritional status among fishermen’s children in Terengganu
The aim of this study was to assess diet quality and its association with nutritional status among 7 to 12 years old fishermen’s
children in Terengganu. The dietary intake data and nutritional status of 100 fishermen’s children were obtained using twoday
24 hours dietary recall and Body Mass Index. Diet quality of the subjects was assessed using the Healthy Eating Index.
61% of subjects had normal BMI, 22% had a BMI below the normal range, and 17% had their BMI above the normal range.
The diet quality of subjects was poor, with mean total HEI score of 50.45±5.27 out of 100 points. The low median scores of
the five food groups, particularly for the vegetable (0.83), fruit (0.00) and dairy (0.00) components, indicates the poor
compliance of the fishermen’s children with the dietary guidelines. No significant association was found between total HEI
score and BMI of the subjects (χ2=0.051, p=0.821). Thus, BMI did not reflect the diet quality of the fishermen’s children in
this study. The findings of this study provide additional information on the diet quality and nutritional status of fishermen’s
children in Terengganu, on the East Coast of Peninsular Malaysia
