Chiquita Prahasanti, Aulanni’am Aulanni’am
play a role as a bridge between innate immune system and adaptive immune system, playing an important role in body’s defense against invading germs. Thus, the introduction of TLR-4
can be used as a marker for aggressive and chronic periodontitis. This research aimed to analyze the expression of TLR-4
in patients with aggressive and chronic periodontitis. The samples in this study were derived from tissue suffering from aggressive and chronic periodontitis. The number of samples in this research was 40 patients with aggressive periodontitis and 40 patients with chronic periodontitis. Then, TLR-4 expression test was conducted by using immunohistochemistry. Based on the results of T-test, a statistical test, it is known that t value was 5.697 with significant value about 0.000 (α = 5%). It is also known that there was significant difference of TLR4
protein expression between in patients with aggressive periodontitis and in those with chronic periodontitis. Morever, based on a box plot diagram, it is known that there was significant difference of TLR4
protein distribution between in patients with aggressive periodontitis and in those with chronic periodontitis. Besides, it is also known that TLR4
protein expression has an effect on the incidence of patients with aggressive periodontitis and chronic periodontitis, as well as the shape of the regression equation. Furthermore, it is known that OR
estimated value for the variable expression of TLR4
protein was 1.275 (sign = 0.000). It indicates that if TLR4
protein expression increased 1 (one) unit, then the risk of aggressive periodontitis could be 1,275 times. Conclusion: The increasing of TLR4
protein expression in patients with aggressive periodontitis indicates that cytokine becomes an indicator of inflammation in aggressive periodontitis.

Several studies have been reported behavioral changes in patients with type 1 diabetes mellitus (T1DM) recently. The increasing levels of glucose affects neuronal activity and may inhibit the process of differentiation and regeneration of neurons in the brain. Dopaminergic (DA) neurons produce dopamine as a neurotransmitter which has an important role to regulate motor functions in the brain. This study aimed to determine the effect of exposure to high concentrations of glucose on the activity of dopaminergic neurons on early development of zebrafish (Danio rerio). Zebrafish embryos were exposed to glucose (1%, 3% and 5%) as a diabetic animal model at the beginning of development. Co-incubation was performed by incubated both of glucose and L-DOPA. Swimming distance of zebrafish larvae was measured as a parameter to determine the motor function regulated by dopamine activity. Results of statistical analysis in zebrafish embryos exposed to 1% and 3% glucose showed significant differences (p <0.05) reduction on swimming distance. Co-incubation glucose with L-DOPA partially increased the swimming distance. It can be concluded that the administration of excessive exposure to glucose was able to decrease the activity of dopaminergic neurons by decreasing the distance of swim in early zebrafish development.

Mahuya Patra Purkait, Koushik Bhattacharya
Background: Carrying heavy loads in the hilly region, porters face extreme ranges in terrain condition, sloped path that is very steep and lack of oxygen due to altitude. The porters in Sikkim, India, routinely carry head-supported loads, which often exceed their body weight, over long distances up and down the steep mountain footpaths which prompted us to assess occupational health status of these head supported load carrying porters. Objective: We aimed our study to evaluate physical and physiological status of male porters of Gangtok, Sikkim. Methods: Seventeen male porters and twenty one healthy as well as age matched (Age: 37 – 52 years) control subjects were selected for the study. Different physical, anthropometric and physiological parameters were studied. Students “t” test was performed to find out the significant difference (P<0.05), if any, between the selected variables. Results: Results of this study on male porters suggest that they are physically healthy but having spinal shrinkage along with lower hand grip strength and PEFR. Conclusion: This study supports the hypothesis that the male porters are associated with decreased lung function and increased spinal shrinkage. To develop an effective intervention strategy, the treatment seeking behavior of individuals would also need to be improved through awareness program.

Kartika Rahma, Mitsuyo Kishida, Sasangka Prasetyawan, Aulanni’am Aulanni’am
Impaired glucose balance affects the regeneration of neurotransmitters in the brain. One of neurotransmitters that is known to have an important role in the brain is dopamine. Dopamine production by dopaminergic (DA) neurons is regulated by the enzyme tyrosine hydroxylase (TH). Previous research has been reported that a decline on TH expression in DA neurons was a result of exposure to excess glucose. One contributing factor is an excess amount of glucose, which interfere homeostasis in the body by producing reactive oxygen species (ROS) more and cause oxidative stress. This condition can cause damage to cells in the brain, including DA neurons, to cell death occurs (apoptosis). The characteristic of neuroprotective owned by the hormone estrogen allegedly able to protect nerve cells from the damaging effects of this. The aim of this study is to explore the involvement of 17β-Estradiol as neuroprotection on the effects of glucose exposure during early development on dopaminergic neurons. This study used zebrafish (Danio rerio
) embryos as animal model. They were divided into 4 groups: negative control group, hyperglycemia group, group that was co-incubated glucose and estrogen, and the group that only incubated with estrogen alone. Cell death (apoptosis) in the brain was observed using acridine orange staining and TH expression was observed using immunocytochemistry. The results showed that the embryos were exposed to 5% glucose significantly (p <0.05) increased the number of apoptotic cells and decreased the expression of TH. While the results of the analysis of embryos in co-incubation group with estrogen showed improvement with decreased apoptotic cells and the increasing expression of TH up to the normal amount. It can be concluded that estrogen shown to have neuroprotective effect in protecting the decreasing TH expression, as the effects of glucose exposure, which could potentially lead to diabetes, by acting as an antioxidant through cellular mechanisms in the central nervous system.

Hypertension is an abnormality of cardiovascular condition, marked by high-blood pressure over normal condition. One of the factors that causes hypertension is altered equilibrium of Renin-Angiotensin-Aldosteron system, which commonly caused by genetic disorder, could produces excess of Angiotensin II which known as vasoconstrictor. Angiotensin II elevates body’s blood pressure and stimulates production of free radicals causes hypertension and oxidative stress. This research conducted to explore potential antihypertension effect from bakasang’s peptide extract made from fermented skipjack tuna (Katsuwonus pelamis L.) based on MDA levels in sera and iNOS expression in cardiac tissue from hypertension rats (Rattus norvegicus) induced by DOCA-salt. Rats were divided into five groups, they were: (1) negative control group, (2) hypertensive control group, (3) hypertension with captopril therapy with dose of 5 mg/kg of body weight (BW), (4,5) bakasang’s peptide extract therapy with dose of 200 mg/kgBW, and 300 mg/kgBW respectively. The results showed that bakasang’s peptide extract with dose of 200 mg/kgBW significantly decrease (p<0.05) MDA level in sera and iNOS expression in cardiac tissue. MDA level decreased up to 32.77%, and iNOS level of expression decreased up to 34.46 % after therapy using bakasang’s peptide extract on hypertension rats. It can be concluded that bakasang’s peptide extract has antihypertension effect (ACE-inhibitor), and capable to decrease MDA levels in sera and iNOS expression in cardiac tissue on hypertension rats induced by DOCA-salt.

This study was performed in order to investigate how the foliar spray of propolis aqueous extract can influence the vegetative growth and flowering characters, chemical constituents and oil composition of Calendula plants. The aqueous extract was applied at four levels (0, 5, 10, 15 and 20 gL-1
). It was revealed that propolis was of a positive effect upon all studied parameters; there was an increase done due to the application of the aqueous extract of propolis. The highest results were obtained due to the application of 5, 10 and 15 g L-1
from the aqueous extract of propolis compared to 20 g L-1
and the control plants. 5 and 10 g L-1
gave the highest records of vegetative characters. While, 15 g L-1
had the highest records of all flowering attributes. In chemical composition optimum results ranged between 10 and 15 gL-1
. The highest percentage of the most important components of the essential oil; sesquiterpene hydrocarbons (cadinene, α-Muurolene and Muurolene) and sesquiter phenols (α- cadinol, α-Cadinol (Epi) and α-Muurolol (Epi)) resulted from 15 g L-1
. Hence, it could be suggested that propolise aqueous extract could be sprayed on calendula plants at a rate not exceeding 15 g L-1
to get higher results.

The combination of anticancer drugs in nanoparticles has great potential as a promising strategy to maximize efficacies by eradicating resistant, reduce the dosage of the drug and minimize toxicities on the normal cells. Gemcitabine (GEM), a nucleoside analogue, and atorvastatin (ATV), a cholesterol lowering agent, have shown anticancer effect with some limitations. The objective of this in vitro
study was to evaluate the antitumor activity of the combination therapy of GEM and ATVencapsulated in a microemulsion (ME) formulation in the HCT116 colon cancer cells. The cytotoxicity and efficacy of the formulation were assessed by the 3- (4,5dimethylthiazole-2-yl)-2,5-diphyneltetrazolium bromide (MTT) assay. The mechanism of cell death was examined by observing the morphological changes of treated cells under light microscope, identifying apoptosis by using the ApopNexin apoptosis detection kit, and viewing the morphological changes in the chromatin structure stained with 4′,6-diamidino-2-phenylindole (DAPI) under the inverted fluorescence microscope. It has been found that reducing the concentration of GEM loaded on ME (GEM-ME) from 5μM to 1.67μM by combining it with 3.33μM of ATV in a ME formulation (GEM/2ATV-ME) has preserved the strong cytotoxicity of GEM-ME against HCT116 cells. The current study proved that formulating GEM with ATV in ME has improved the therapeutic potential of GEM and ATV as anticancer drugs.

Asmaa Ahmed Mahmoud, Fateheya Mohamed Metwally, Hend Mohamed Rashad, Hanaa Hamdy Ahmed, Asmaa M Elfiky, Aboelfetoh Mohamed Abdalla
showed an evident role against obesity and leptin resistance. However, Moringa oleifera
potential effects on alteration of moods, cognitive as well as motor deficits in obese animal model have not been evaluated in a mechanistic way. So, the aim of the current study is to examine the potential of Moringa oleifera
to induce cerebral leptin mRNA expression, and consequently its effects on amelioration of behavioral and biochemical alterations in obese female rats. Ethanolic extract of Moringa oleifera
was orally administered (600 mg/kg b.wt) for 12 weeks to those obese rats. Memory behavior, depression- and anxiety-like behavior, as well as motor activity were examined by object recognition test, forced swim test, light and dark test, and open field test, respectively. Leptin mRNA gene expression and its concentration were determined in cerebral cortex using quantitative real time-PCR and ELISA, respectively. Oxidative stress markers malondialdehyde and glutathione were also evaluated in the cerebral cortex. Moringa oleifera
significantly up-regulated cerebral leptin mRNA expression and its level, as well compared to control obese rats. Moreover, Moringa oleifera
decreased lipid peroxidation significantly, whereas they improved glutathione significantly in comparison with those untreated rats. Regarding behavioral deficits, Moringa oleifera
attenuated the declined memory, depression and anxiety- like behavior, as well as the motor deficit that observed in obese untreated rats.
This study indicated the potential of Moringa oleifera
in triggering cerebral leptin mRNA expression, hence protection of brain from oxidative damage as well as improvement of cognition, moods and motor deficits in obese rats.

Muna Abdulwahab Khaleel, Amean A Al-Yaseri
The researchers had conducted this descriptive study aimed at given the nursing students at university of Babylon chance to reflect on their opinions of clinical teaching and evaluation. The study consisted of (136) third and fourth year nursing students from college of nursing/University of Babylon. Data were gathered by using questionnaire form which consisted of four items (21 statements). All items were rated on 3 Point Likert Scale whereas (Always, Sometimes and Never). Data analysis was done through the application of simple descriptive statistical methods such as frequencies and percentages to assess the results of the study. The results of the study indicated that some of the teaching skills of the clinical teacher components are at accepted levels, other like quality of bedside teaching (integrating theory to practice) needs more efforts on the part of the teacher. Also, results showed the responses for the statement clinical teacher provided chances to practice skills (37%) and responses to statement encouraged students to actively participate in the discussions (37%) needs to be looked into future. As well as results showed that the opportunities for practicing nursing skills, (46%) seems to show that less than half of the students are able to achieve these opportunities. The study concluded that the learning environment created by the teacher and his/her characteristics can and does have a profound effect on learning and the challenge for nurse education is to provide learning experience that facilitates the so called knowledge doer. Finally, the study recommended the necessity for improving the quality of the theoretical knowledge and bedside teaching in the clinical area and emphasized on provision for more chances to practice skills.
