Fatty acids in fish and beef and their nutritional values: a review.

This review aims to summarize the latest developments and recent knowledge regarding the fatty acids in fish and beef, their profiles and nutritional values. The paper covered the types of different fatty acids such as unsaturated fatty acids (UFA), polyunsaturated fatty acids (PUFA), especially the omega-3 in different fish species. The study also summarized the nutritional values of the fatty acids as compared to those in other animal species. However, the strategies influencing the fatty acid composition of beef were also reflected. The study revealed that many fatty fishes were found as excellent sources of UFA and PUFA, especially the omega-3. On the other hand, beef was proposed major source of saturated fat in a diet. The quality attributes of beef meat such as tenderness, juiciness, and flavor intensity have been shown to be affected by the chemical properties and lipid content. Moreover, increasing dietary omega-3 fatty acid intakes for potential health benefits for protecting against cardiovascular diseases was recommended. This work may assist the researchers and scientists to have a clear picture about what have been achieved earlier and what critical work should be conducted in future

The motives behind the deception and propaganda used by the elite & political leaders: a Qur’anic – mass communication perspective

Propaganda has been one of the main issues and hot topics in Human Sciences that is of great concern in our contemporary world. The Elite and the Political leaders through the ages used all sorts of deceptions, manipulation and disinformation not only to propagate their agendas but also for easy control of the masses. Undoubtedly, there are many reasons for that. But what are the main motives behind such dirty tricks and tactics? This study is an attempt to answer the abovementioned question and to shed light on the role the elite and the political leaders play in deceiving the public. It is extremely important for the Muslims of all generations to be familiar with all sorts of deceptions and propaganda adopted by the elite and the overbearing political leaders so as to avoid being trapped and being misled by them. The scope of the study will be the Qur‟anic perspective pertaining to the motives behind deception and propaganda used by the elite & the political leaders in deceiving the masses. To address the problem under study, three research methods shall be adopted; namely: descriptive, analytical, historical and, to some extent, comparative methods. This new attempt of its kind is considered to be an integrated Qur‟anic-Mass Communication study

Pragmatic Explicitation Strategy in Rendering of Tayeb Salih's Season of Migration to the North into English: A Socio-cultural Study

The current paper aims to  study critically how the translator(Denys Johnson-Davies) has employed  explicitation strategy in rendering the novel of Tayeb Salih's'' Season of Migration to the North into English''. The objective of the study is to examine the usage of explicitation strategy by the intended  translator in rendering the novel  from Arabic into English. The novel has many complicated symbols  and  many literary and thematic techniques such as the reference to the Nile, the sand, the palm tree which may pose  some  lexical and cultural challenges for the translator to reproduce the text into the target language. The data to be analyzed here is a set of  selected expressions chosen randomly from various pages  of the intended  novel. The selected data were then classified on the basis of reasons for which explicitation strategy was used and the effectiveness of explicitation strategy in rendering  some cultural expressions into English . The result of the study reveals  that the translator (Denys Johnson-Davies)has resorted to some  types of explicitation strategy categorized by Klaudy. They are : the obligatory, optional and pragmatic  explicitation such as (addition ,substitution ,  recasts and  narrowing ( specification). Keywords: Explicitation Strategy, symbols, challenges, pragmatic, addition, substitution DOI: 10.7176/JLLL/57-05 Publication date:June 30th 201

New Approach in Detection MAC Spoofing in a WiFi LAN

Medium Access Control (MAC) spoofing attacks relate to an attacker altering the manufacturer assigned MAC address to any other value. MAC spoofing attacks in Wireless Fidelity (WiFi) network are simple because of the ease of access to the tools of the MAC fraud on the Internet like MAC Makeup, and in addition to that the MAC address can be changed manually without software. MAC spoofing attacks are considered one of the most intensive attacks in the WiFi network; as result for that, many MAC spoofing detection systems were built, each of which comes with its strength and weak points. This paper logically identifies and recognizes the weak points and masquerading paths that penetrate the up-to-date existing detection systems. Then the most effective features of the existing detection systems are extracted, modified and combined together to develop more powerful detection system called Sequence Number with Rate and Signal Strength detection method (SN-R-SS). SN-R-SS consists from three phases. First phase is Window Sequence Numbers; to detect suspicious spoofed frames in the network. Second phase is Transmission Rate Analysis; to reduce the amount of the suspicious spoofed frames that are generated from the first phase. Finally, the third phase is Received Signal Strength; this phase is decisive phase because it decides whether the suspicious spoofed frames are spoofed or not. Commview for WiFi network monitor and analyzer is used to capturing frames from the radio channals. Matlab software has been used to implement various computational and mathematical relations in SN-R-SS. This detection method does not work in a real time because it needs a lot of computation.

The relationship between water activity and fish spoilage during cold storage : a review

This review paper presents clearer picture about the relationship between spoilage of cold stored fish and water activity. The paper was an attempt of presenting the recent existing information and the latest development in this regard. It covered the relationship between water activity and moisture content, water activity control, spoilage of fish and its different phases and the relationship between the spoilage and water activity. The paper revealed that during the initial period of storage some of the characteristics of the fish product reduce in intensity or are lost and in the later stage bacterial degradation of tissues became evident. The water activity (aw) played an important factor in fish spoilage and the growth of different microorganisms depends on its rate. If the aw reduced to 0.6, the growth of bacteria and moulds can be prevented. The detection of spoilage can be determined by controlling water activity and in the same time can be retarded by reducing the aw of the fish by either drying or freezing to keep the fish in good stage with high nutritional and organoleptic quality. The information presented in this study is very important and can assist in preventing spoilage of fishes and their products particularly when production and processing operations are applied

Prevalence Rate of Congenital Fetal Malformations in Second Trimester by Ultrasound Scanning in Zagazig University Outpatient Clinic

Background: All pregnancies are at a risk of producing congenital malformations, though only some of them are at a greater risk. Congenital anomalies its problem in which abnormalities of structure, function or body metabolism resulting in physical or mental disability or it may be fatal.Objective: This study aimed for early detection of major fetal anomalies to improve fetal and maternal outcome.Patients and methods: This cross-sectional study that include 422 pregnant females was carried out at the Ultrasound Unit and Obstetrics & Gynecology Department, Faculty of Medicine, Zagazig University during the period from December 2018 to July 2019. Results: Ultrasonography can identify at least 35-50% of major fetal malformations with a specificity of 90-100%. Though other methods of screening like biochemical markers and karyotyping are available, ultrasonography has the advantage of being non- invasive, safe, fast, accurate and reproducible with real time display, causing no discomfort to the patient at any time of gestation.Conclusions: The Prevalence of congenital fetal malformations (CFMF) among the study participants using ultrasonography scanning was 3.6%. The most prevalent anomalies were Hydrops fetalis and CVS anomalies. Therefore screening for congenital anomalies in obstetric sonography is an important component of primary healthcare for maternal and child health

The Effect Of Culture System On Embryonic Development and Aneuploidy Rate For Icsi Cases

Background: Patients undergoing intracytoplasmic sperm injection (ICSI) or in vitro fertilization (IVF)cycles often suffer from recurrent implantation failure (RIF). To ensure live birth and embryonic viability, culture systems should be optimized in all ICSI and IVF cycles. The success of IVF can be affected by the culture systems employed for embryonic development. It has been argued that covering micro drops with oil in culture systems can prevent microbial infection, ensure suitable osmotic and pH conditions, and prevent the evaporation of the medium. Objectives: Comparing the embryonic development, euploidy rate ,and clinical outcome of using GPS Dishes covered with paraffine oil and SPL Dishes with mineral oil for patients with previous RIF. Patients and methods: the study was a prospective randomized controlled trial and the sample size consisted of 174 patients undergoing ICSI cycles at a private fertility center during the period between April 2017 and March 2020. Patients’ embryos were randomly assigned into one of the two of the aforementioned groups. Results: The two groups weren’t statistically significantly different in male age, female age, collected oocyte number, number of mature oocytes, and number of blastocysts undergoing preimplantation genetic diagnosis (PGD-A). For the preimplantation parameters of the embryos, fertilization, cleavage, and high-quality blastocyst rates were statistically significantly higher in the GPS Dishes with paraffin oil group than in the SPL Dishes covered with mineral oil group (77.5, 80.1, and 79.45%) (p = 0.012, and 0.001). Conclusion: we conclude that embryonic development can be enhanced by using GPS Dishes with paraffin oil overlying

Synthesis, spectroscopic, thermal and anti-microbial studies of transition metal complexes of hydrazone derived from 4,6-diacetylresorcinol and S-methyldithiocarbazate

New series of copper(II), nickel(II), cobalt(II), zinc(II), cadmium(II), iron(III) and oxovanadium(IV) complexes of hydrazone, H3L, ligand derived from the condensation of S-methyldithiocarbazate and 4,6-diacetylresorcinol, in the molar ratio 1:1, has been synthesized. All the metal complexes are dimmers. The structures of the ligand and its transition metal complexes were characterized by elemental analyses, spectral (Infrared, electronic, Mass, 1H NMR and ESR) data and magnetic susceptibility, molar conductivity measurements and thermal gravimetric analysis. The structure of the ligand is dibasic tridentate with ONS sites. The bonding sites, in all cases, are the azomethine nitrogen, phenolic oxygen and thiol sulfur atoms, as illustrated from the spectral data. The metal complexes exhibit different geometrical arrangements such as square planar, tetrahedral, square pyramidal and octahedral arrangements. Kinetic parameters (DG, DH, DS and DE) of the metal complexes were calculated from the thermal behaviour of the metal complexes using Coats-Redfern method. The ligand and its metal complexes were screened for its antimicrobial activity against Staphylococcus aureus and Staphylococcus pyogenes as Gram-positive bacteria, Pseudomonas phaseolicola and Pseudomonas fluorescens as Gram-negative bacteria and the fungi Fusarium oxysporum and Aspergillus fumigatus

Uncommon case of hydrosalpinx-induced adnexal torsion in a postmenopausal woman

Adnexal torsion is a twisting of the adnexa, including the ovary and/or the fallopian tube, around its own vascular axis. Most cases of adnexal torsion occur in women of reproductive age and only rarely in postmenopausal women. Here, we report a case of 58-year-old woman, postmenopausal for 6 years, who presented with acute lower abdominal pain. Ultrasound scan showed a right-sided, well-circumscribed, cystic mass measuring 50x57 mm with low level echoes. Doppler evaluation revealed no blood flow signals inside the mass. Abdominal exploration revealed right adnexal torsion. Salpingo-oophorectomy was done and histopathological examination revealed a twisted, gangrenous hydrosalpinx with no pathological lesion in the ovary. The patient was discharged on the fourth postoperative day. Although adnexal torsion in postmenopausal women is a rare event, it should not be ignored in those women who present with abdominal pain. A longer delay between admission and surgery may be attributed to the rarity and non-specific symptoms of the disease in this age group

Efficacy of oral celecoxib and hyoscine butyl-bromide versus placebo during copper intrauterine device placement in women delivered only by elective cesarean section: a randomized controlled study

Objective: To compare the efficacy and tolerability of celecoxib to hyoscine butyl bromide (HBB) and placebo in reducing pain scores during placement of copper intrauterine devices (IUD) in parous women who have undergone elective cesarean section and who have had no previous vaginal deliveries. Methods: We conducted a randomized, double-blind, placebo-controlled trial at a tertiary University hospital from April 2018 to September 2018. The study included women who had never delivered vaginally and who desired copper IUD insertion. We randomized the study participants in a 1:1:1 ratio to celecoxib, HBB or placebo groups. They took the tablets orally two hours before IUD insertion. The study outcomes were the self-reported pain measurements, using a 10-cm Visual Analogue Scale (VAS), taken during tenaculum placement, sound insertion, IUD insertion and five minutes post-insertion, as well as an ease of insertion score. Results: The study included 105 women (n=35 in each group). The baseline characteristics were similar among all groups. The mean pain score in the celecoxib group was lower during IUD insertion than placebo (1.97 vs 4.34, p<0.001). Moreover, the ease of insertion score was significantly better with celecoxib [1.56 vs. 3.03, p< 0.001] than with placebo. Similarly, Women in the HBB group were more likely to report lower pain scores during IUD insertion (2.91 vs 4.34, p<0.001) and lower ease of insertion score [1.43 vs. 3.03, p< 0.001]. Conclusions: The use of celecoxib and HBB may both reduce the pain associated with copper IUD insertion among women with no previous vaginal delivery. However, celecoxib is better tolerated with fewer side effect
