Abstract: The sagittae mass asymmetry was studied in the teleost Lutjanus bengalensis and it is calcula-ted as the difference between the mass of the right and left paired otoliths divided by average otolith mass. As in the case of other symmetrical fish species, the result of the present study showed that the absolute value of sagittae mass asymmetry (X) in L. bengalensis does not de-pend on fish length and otolith growth rate. On the other hand, the absolute value of otolith mass asymmetry is increased with the fish length. The value of sagittae mass asymmetry falls between -0.2 and +0.2.

Suvitha Syam,Siddig Ibrahim Abdelwahab,Mohammed Ali Al-Mamary,Syam Mohan
Molecules , 2012, DOI: 10.3390/molecules17066179
Abstract: Several chalcones were synthesized and their in vitro cytotoxicity against various human cell lines, including human breast adenocarcinoma cell line MCF-7, human lung adenocarcinoma cell line A549, human prostate cancer cell line PC3, human adenocarcinoma cell line HT-29 (colorectal cancer) and human normal liver cell line WRL-68 was evaluated. Most of the compounds being active cytotoxic agents, four of them with minimal IC50 values were chosen and studied in detail with MCF-7 cells. The compounds 1, 5, 23, and 25 were capable in eliciting apoptosis in MCF-7 cells as shown by multiparameter cytotoxicity assay and caspase-3/7, -8, and -9 activities (p < 0.05). The ROS level showed 1.3-fold increase (p < 0.05) at the low concentrations used and thus it was concluded that the compounds increased the ROS level eventually leading to apoptosis in MCF-7 cells through intrinsic as well as extrinsic pathways.

International Journal of Pharmacology , 2012,
Abstract: Palm date fruits have been used extensively for the traditional cure of liver illnesses and malaria in the Arab Peninsula. Therefore, the aim of the present study was to evaluate for the first time the in vivo hepatoprotective and the antioxidative effects of different varieties of palm date fruits in relation to their total phenolic contents and total flavonoids. This study was carried out using the CCl4-induced liver injuries in rabbits for two different periods: 4 and 20 h after CCl4-subcutaneous injection and oral administration of palm date syrups (5 g kg-1 b.wt.). The antioxidative and hepatoprotective effects of palm date syrups during the first and second experimental periods (4 and 20 h) were very clear, since results of plasma ALT and AST and TBARS (from liver homogenate) of the control were significantly higher than those obtained from animals treated with syrups. The present findings do strongly recommend to increase the consumption of palm date fruits, especially in cases of liver diseases and for the prevention of other serious diseases such as cardiovascular and cancers.

Evidence-Based Complementary and Alternative Medicine , 2012, DOI: 10.1155/2012/829401
Abstract: Hepato- and nephrotoxicity of Khat consumption (Catha edulis Forskal) have been evoked. Therefore, this study was conducted to evaluate such possible hepatorenal toxicity in female and male Sprague-Dawley rats (SD rats) focusing primarily on liver and kidney. In addition, female and male rats were investigated separately. Accordingly, forty-eight SD-rats (100–120 g) were distributed randomly into four groups of males and female (). Normal controls (NCs) received distilled water, whereas test groups received 500 mg/kg (low dose (LD)), 1000 mg/kg (medium dose (MD)), or 2000 mg/kg (high dose (HD)) of crude extract of Catha edulis orally for 4 weeks. Then, physical, biochemical, hematological, and histological parameters were analyzed. Results in Khat-fed rats showed hepatic enlargement, abnormal findings in serum aspartate aminotransferase (AST), and alkaline phosphatase (ALP) of male and female SD-rats and serum albumin (A) and serum creatinine (Cr) of female as compared to controls. In addition, histopathological abnormalities confirmed hepatic and renal toxicities of Khat that were related to heavy Khat consumption. In summary, Khat could be associated with hepatic hypertrophy and hepatotoxicity in male and female SD-rats and nephrotoxicity only in female SD-rats.

Abstract: In this review article, various preferences in breast plastic surgery particularly after breast cancer will be discussed in view of the diverse indications for the different construction procedures. The various conditions that necessitate the need for reconstruction are appraised, the important reconstructive procedures are discussed. The most important indications procedures discussed in this review include; Prophylactic subcutaneous mastectomy, Lumpectomy and Radiation, Modified Mastectomy with Axillary Sampling, Nipple reconstruction, and the contralateral breast. These procedures are discussed in view of plastic surgeon practice and patients acceptability in Saudi Arabia. Data from Saudi Arabia in particular was identified through searches of the EMBASE, and MEDLINE database, using the keywords: Saudi Arabia, breast plastic Surgery, breast reconstruction, autologous breast reconstruction, breast augmentation. Advances in prosthetic technologies and modifications in autologous flap techniques, and the development of novel tissue alternatives have allowed for sustained developments in breast reconstruction results. A variety of attitudes has been accessible for addressing the difficulties that endure after resection of breast cancer in Saudi Arabia. Patients should be educated to accept different process in this context.
FLUCTUATING ASYMMETRY IN THE OTOLITH WIDTH OF Carangoides caeruleopinnatus (CARANGIDAE) COLLECTED FROM MUSCAT CITY COAST ON THE SEA OF OMAN
Laith Jawad,Juma Al-Mamry,Dawood Al-Mamari
Ribarstvo : Croatian Journal of Fisheries , 2012,
Abstract: The fluctuating asymmetry in two otolith dimensions, the length and width of adult teleost Carangoides caeruleopinnatus were calculated. The highest asymmetry value was observed in the otolith width. The fish length groups 201-210 and 281-290 mm showed the lowest and the highest value of asymmetry respectively. In addition, few fish length groups have shown zero value for otolith size asymmetry. Different pollutants and their presence in the area appeared to be one of the reasons that cause the asymmetry in this species. A trend of increase in the asymmetry values with the fish length was noticed for the otolith length and width.

Abstract:

Background: The comorbidity between chronic physical conditions and psychosocial health consequences is becoming a research interest for researchers in the field. The purpose of this study was to investigate the psychosocial health status of patients diagnosed with chronic illnesses in Jordan. Methods: A cross sectional survey using 806 patients diagnosed with chronic illnesses has been used to collect data in regards to depressive symptoms, psychological distress, coping, optimism, life satisfaction, and perceive social support. Results: 17.5% of the patients reported that they had moderate to severe depressive symptoms, and about 50% of them had high level of optimism and life satisfaction, moderate level of effectiveness of coping skills, psychological distress, and perceived social support from family, friends and others. There were significant association between patients’ age and their scores on perception of social support from family, friends and others, life satisfaction, and psychological distress (p > 0.05). While, male and female patients were different in their depressive symptoms (t = -2.57, p = 0.01), perceived social support from others (t = -2.06, p = 0.04), and optimism (t = 2.29, p = 0.02). Also, patients had differences in their depressive symptoms, perceived social support from friends, others and friends, optimism, life satisfaction, and psychological distress related to their medical diagnoses (p < 0.05). Conclusion: Patients with chronic illness are in need for psychological care, and periodic psychological screening is one step toward maintaining their psychological wellbeing.

Effect of Salt Stress on the Performance of Six Soybean Genotypes
Talib A. Essa,Dawood H. Al-Ani
Pakistan Journal of Biological Sciences , 2001,
Abstract: The effect of salinity on growth and chlorophyll content of six soybean genotypes was investigated. Plants were grown in nutrient solution in a greenhouse experiment to determine the effect of salinity on growth and Chl. a and b content of soybean leaves. Salinity was induced by natural drainage water of salted field to the nutrient solution. Electrical conductivities of the nutrient solution were 2,4,6,8,and l0 ds/m. Salinity induced marked decrease in plant growth and chlorophyll content of soybean genotypes. Increasing salinity level to l0 ds/m decreased plant height, shoot and root dry weight, and Chlorophyll a and Chlorophyll b contents. Soybean genotypes responded differently to increasing salt concentrations. There was a consistent in the percentages reduction of shoot dry weight and Chorophyll a and Chlorophyll b contents. It seems that Lee, Coniquitt and Clark 36k are more tolerant than other genotypes. Chlorophyll a and b content of soybean leaves with or without shoot dry weight can be use as a parameter in screening for salt tolerant in soybeans.

Oman Medical Journal , 2010,
Abstract: This is a case report of a 59 years old male who had a commercial non-related living renal transplantation for his end stage renal insufficiency secondary to adult polycystic kidney disease. He suffered an immediate and early post-operative bleeding, which was managed conservatively. He was presented at Sultan Qaboos University Hospital four months after his transplant with abdominal pain, nausea, loss of appetite and a rise in serum creatinine levels. Ultrasonography and angiography have shown a 4 cm false aneurysm of the transplant renal artery at the anastomotic site with the external iliac artery. Surgical exploration with resection of the false aneurysm and reanastomosis of the donor renal artery to the external iliac artery was carried out successfully with preservation of the renal allograft. This is a rare case of an extra-renal false aneurysm at the anastomotic site of the transplant renal artery to the external iliac artery four months after renal allotransplantation. Literature review on the management and outcome of false aneurysms after renal transplant was carried out.
Comparison of Surface Modification of CR-39 Polymer Film Using RF and DC Glow Discharges Plasma  [PDF]
Mohamed Hassouba, Nagia Dawood
Journal of Modern Physics (JMP) , 2017, DOI: 10.4236/jmp.2017.812122
Abstract: Surfaces of optical elements are deposited by antireflection coatings (ARCs) to decrease the reflection of light. Surface needs treatment before depositing the ARC one of treatment processes by plasma for adhesion improvement and surface hardening. A comparison of RF and DC glow discharges treated CR-39 polymer films gives insight into the mechanism of these surface processes. The surface properties of the plasma-treated samples are examined by microscopy techniques include contact angle measurements, scanning electron microscopy (SEM), atomic force microscopy (AFM), infrared (IR) spectroscopy and refractive index measurements. Results show that the plasma treatment modifies the polymer surface in both composition and morphology. It is found that the surface wettability is enhanced after plasma treatment. It is found that, RF plasma is more effective than DC plasma in CR-39 surface modification, as it implants more oxygen atoms into the surface and makes the contact angle declining to a lower level.
