( Mohamed,Ahmad Martadha ),( Damin,Zahrul Akmal ),( Kim,Pan Suk ) 한국외국어대학교 동남아연구소 2015 東南亞硏究 Vol.25 No.1

Food security implies the ability of the country to ensure a stable supply for domestic consumption. To achieve that, the Malaysian Federal Government has to allocate a certain percentage of the national budget for food production. Within this framework, this article attempts to examine policies regarding food security in Malaysia. Since the Malaysian government initiated agricultural policies to provide sustainable food production, the percentage of budgetary allocation for food has varied substantially over the years. Prior to the establishment of the industrial policy, the budgetary allocation for food related policies was quite high. However, the influence of global warming as well as a series of catastrophic events in food producing nations such as Thailand and Australia has forced Malaysia to relook at its food security agenda. Using a content analysis method, based on the documents of the Malaysia economic development plans, this paper first explores government policies on food and agriculture. Then, the paper examines how these policies affect the balance of trade in regards to food availability in terms of three major commodities (rice, fruit, and vegetables). Finally, the researchers analyze the future direction of Malaysia in regards to the food security agenda focusing on food availability. It is hopeful that the recommendations will help policymakers formulate agricultural policies which can help the country to sustain its food production and at the same time protect the country from any unforeseen circumstances relating to food security issues.

Heba K,Mohamed1,Sohair A,Eltony 대한해부학회 2020 Anatomy & Cell Biology Vol.53 No.1

Epilepsy is one of the most common neurological disorders, its prevalence approximately from 0.5% to 2% of the general population. Generalized seizures could lead to several morphological changes in the brain. This study aimed to investigate the morphological effects of a single convulsive dose of pentylenetetrazol (PTZ) on rat dentate gyrus at different postnatal ages. Thirty-six male Wistar rats were used at the following postnatal ages: P10, P21, and P90 (12 rats per each age). The animals in each age were equally divided into two groups: group I, control and group II, treated with a single intraperitoneal injection of PTZ (55 mg/kg). After confirmation of generalized tonic-clonic seizures, specimens from the right dentate gyrus were processed for light and electron microscopy. In PTZ-treated groups, the number of granule cells significantly decreased. Dark granule cells appeared in the deep layers of the granule cells in P10 and with the progress of age, they significantly increased in number and extended into the superficial layers of the granule cells. The dendritic spines diminished. Glial fibrillary acidic protein and caspase-3 expression increased. Ultrastructurally, granule cells showed irregular shaped nucleus, dilated rough endoplasmic reticulum (RER) cisternae, mitochondria with damaged cristae, large vacuoles, lysosomes, and lipofuscin granules. Dark granule cells characterized by electron-dense nucleus and cytoplasm containing disorganized Golgi bodies, swollen mitochondria with damaged cristae, numerous free ribosomes and few long strands of RER. Astrocytes had hypertrophied cell body. Acute treatment with PTZ-induced epileptic seizures caused toxic effect on the structure of rat dentate gyrus at different postnatal ages.

Fixation of radial head fracture with minimally invasive posterior approach remains a significant challenge. The aim of this study was to determine the feasibility of trans-anconeus posterior elbow approach and to observe lateral ulnar collateral ligament (LUCL) in extended elbows. This cadaveric study was performed in twenty upper limbs of fresh fixed adult male cadavers. An oblique incision was made in the middle segment of anconeus until the lateral ligament complex and the joint capsule had been revealed. A deep dissection was explored to observe the anatomical relationship of the LUCL to the anconeus. Measurements of the LUCL were recorded while the elbow was fully extended. The mean distance between the edge of the radial head and the proximal insertion of the LUCL was 13.3 mm (11.5–16.2 mm); the mean distance between the edge of the radial head and the distal insertion of the LUCL was 20.9 mm (19.2–23.4 mm); the distance between the edge of the radial head and the distal edge of the annular ligament was 11.2 mm (8.22–11.7 mm). By estimate correlation of the previous measurements, the direct and accessible way to expose the posterolateral articular capsule of the elbow joint was through a window in medial 2/3 of the middle segment of anconeus muscle. These trans-anconeus approach is useful. It provides good visualization, facilitates applying the implants, and lessens the risk of radial nerve injury. Awareness of the anatomy is mandatory to avoid injury of LUCL.

This research aims to identify the role that small and medium enterprises (SMEs) can play in achieving the economic goals of the vision of Saudi Arabia 2030. The study relied on descriptive analysis, designing a standard model, and analyzing it using the Eviews9 program. The study also adopted the questionnaire as a tool for data collection. The study area covered Alkharj and Hawtat Bani Tamim governorates. The sample size of the study was 142 participants. The study’s results confirmed the existence of a significant impact of changes in independent variables (X1, X2, X3, X4), which are (GDP, non-oil exports, number of employees, and public revenues), respectively. The dependent variable (Y) represents the number of small and medium-sized businesses in the Kingdom of Saudi Arabia. Additionally, it was found that 61.3% of small and medium-sized enterprises in the governorates of Al-Kharj and Hawtat Bani Tamim operate in the commercial sector. Most study participants concur that SMEs significantly lowered the unemployment rate and helped boost the GDP rate in the Kingdom of Saudi Arabia. The obstacles and difficulties facing the establishment of these enterprises were financial problems, marketing problems, and corporate monopoly. Furthermore, most of the small and medium l enterprises faced financing problems.

Butyrate regulates leptin expression through different signaling pathways in adipocytes

Mohamed Mohamed Soliman,Mohamed Mohamed Ahmed,Alaa-eldin Salah-eldin,Abeer Abdel-Alim Abdel-Aal 대한수의학회 2011 Journal of Veterinary Science Vol.12 No.4

Leptin is an adipocytokine that regulates body weight, and maintains energy homeostasis by promoting reduced food intake and increasing energy expenditure. Leptin expression and secretion is regulated by various factors including hormones and fatty acids. Butyrate is a short-chain fatty acid that acts as source of energy in humans. We determined whether this fatty acid can play a role in leptin expression in fully differentiated human adipocytes. Mature differentiated adipocytes were incubated with or without increasing concentrations of butyrate. RNA was extracted and leptin mRNA expression was examined by Northern blot analysis. Moreover, the cells were incubated with regulators that may affect signals which may alter leptin expression and analyzed with Northern blotting. Butyrate stimulated leptin expression, and stimulated mitogen activated protein kinase (MAPK) and phospho-CREB signaling in a time-dependent manner. Prior treatment of the cells with signal transduction inhibitors as pertusis toxin, Gi protein antagonist, PD98059 (a MAPK inhibitor), and wortmannin (a PI3K inhibitor) abolished leptin mRNA expression. These results suggest that butyrate can regulate leptin expression in humans at the transcriptional level. This is accomplished by: 1) Gi protein-coupled receptors specific for short-chain fatty acids, and 2) MAPK and phosphatidylinositol-3-kinase (PI3K) signaling pathways.

Elshazly Mohamed,EL-Halafawy Yasser Mohamed,Mohamed Dina Zakaria,Wahab Khaled Abd El,Mohamed Tamer Mohamed Kheir 대한마취통증의학회 2022 Korean Journal of Anesthesiology Vol.75 No.6

Background: Overweight and obesity are growing public health concerns worldwide. Bariatric surgery is a modality of weight reduction; however, postoperative pain can increase the length of hospital stay, with all the associated consequences. While regional anesthesia is an available option, the feasibility of performing abdominal wall blocks on patients with obesity is questionable. Methods: Sixty adult patients with a body mass index of 40–50 kg/m2 undergoing laparoscopic bariatric surgery were randomly assigned to receive either an ultrasound-guided transversus abdominis plane (TAP) or erector spinae plane (ESP) block. The primary outcome was the analgesic effect in the first 24 h postoperatively, assessed using the mean visual analog scale (VAS) score. Secondary outcomes were the time required for a successful block, incidence of complications, time to first rescue analgesia, time to flatus or stool passage, and total opioid consumption. Results: The mean VAS score during the first 24 h was higher with the TAP block than with the ESP block (2.78 ± 0.34 vs. 2.32 ± 0.12, P < 0.001). Additionally, the time to first rescue analgesia was greater with the ESP block (P = 0.001) and the time required for a successful block was higher with the TAP block (P = 0.001). However, the incidence of complications, total opioid consumption, and other secondary outcomes was similar between the groups. Conclusions: Compared with the TAP block, the bilateral ESP block is a more feasible and effective method for intra- and postoperative analgesia in patients undergoing laparoscopic bariatric surgery.

Assessment of Some Barley Germplasms Based on RAPD Analysis and Anti-Nutritional Factors

Mohamed, Amal A.,Matter, Mohamed Ahmed,Rady, Mohamed Ramadan 한국작물학회 2010 Journal of crop science and biotechnology Vol.13 No.2

The variation among some barley germplasm (Giza 123, Giza 127, Giza 130, Desert, and Sinai) was investigated comparatively at the molecular and biochemical levels. Leaf DNAs extracted from different barley germplasm were amplified with randomly chosen primers in a Polymerase Chain Reaction (PCR) using Random Amplified Polymorphic DNA (RAPD) technique. Only five primers amplified all DNA templates among 15 primers. Primers generated a total of 112 DNA fragments ranged from 1.2 to 0.1 kbp. Out of the 112 fragments, 16 (14.29%) were polymorphic. The result indicated that fragments generated per primer, with an average of 22.4 products, where the number of polymorphic bands per primer, with an average of 3.2 polymorphic bands. In addition, the genetic variation in the anti-nutritional factors and nutrient composition of the same genotypes were determined. A wide variation in total phenolic, phytic, tannin, vicine, and saponin contents was found among these germplasm. The range of total phenolic was 3.83 to $7.50\;mg\;g^{-1}d.w$. Among all germplasm, Desert germplasm was characterized by the highest tannin content. However, saponin ranged between $5.66\;mg\;g^{-1}d.w$. (in Giza 123) to $9.21\;mg\;g^{-1}d.w$ (in Sinai) germplasm. The concentrations of the phytic acid were generally low, ranging between 0.99 to $6.78\;mg\;g^{-1}d.w$. The germplasm Desert and Sinai had the highest level of vicine, 1.89 and $1.87\;mg\;g^{-1}d.w$., respectively. The results of the molecular characterization and anti-nutritional content can be used as the starting point needed to identify the valuable Egyptian barley germplasm.

Mohamed Hassan Elnaem,Muhammad Eid Akkawi,Nor Ilyani Mohamed Nazar,Norny Syafinaz Ab Rahman,Mohamad Haniki Nik Mohamed 한국보건의료인국가시험원 2021 보건의료교육평가 Vol.18 No.-

Purpose: This study investigated pharmacy students’ perceptions of various aspects of virtual objective structured clinical examinations (vOSCEs) conducted during the coronavirus disease 2019 pandemic in Malaysia. Methods: This cross-sectional study involved third- and fourth-year pharmacy students at the International Islamic University Malaysia. A validated self-administered questionnaire was distributed to students who had taken a vOSCE a week before. Results: Out of the 253 students who were approached, 231 (91.3%) completed the questionnaire. More than 75% of the participants agreed that the instructions and preparations were clear and helpful in familiarizing them with the vOSCE flow. It was found that 53.2% of the respondents were satisfied with the flow and conduct of the vOSCE. However, only approximately one-third of the respondents believed that the tasks provided in the vOSCE were more convenient, less stressful, and easier to perform than those in the conventional OSCE. Furthermore, 49.7% of the students favored not having a vOSCE in the future when conducting a conventional OSCE becomes feasible again. Internet connection was reported as a problem hindering the performance of the vOSCE by 51.9% of the participants. Students who were interested in clinical pharmacy courses were more satisfied than other students with the preparation and operation of the vOSCE, the faculty support, and the allocated time. Conclusion: Students were satisfied with the organization and operation of the vOSCE. However, they still preferred the conventional OSCE over the vOSCE. These findings might indicate a further need to expose students to telehealthcare models.
