ABSTRACT
Abstract The aim of the present study is to assess the effects of selenium nanoparticles on the growth, hematology and nutrients digestibility of Labeorohita fingerlings. Fingerlings were fed with seven isocaloric sunflower meal-based diet supplemented with different concentrations of nanoparticles naming T1 to T7 (0, 0.5, 1, 1.5, 2, 2.5, and 3 mg/kg), with 5% wet body weight while chromic oxide was used as an indigestible marker. After experimentation for 90 days T3 treated group (1mg/kg -1Se-nano level) showed the best result in hematological parameters (WBC's 7.97 ×103mm-3, RBC's 2.98 ×106 mm-3 and Platelet count 67), nutrient digestibility (crude protein: 74%, ether extract: 76%, gross energy: 70%) and growth performance (weight gain 13.24 g, weight gain% 198, feed conversion ratio 1.5, survival rate 100%) as compared to the other treatment groups. Specific growth rates were found significantly higher in T5 than in other groups. The present study indicated positive effect of 1 mg/kg Se-nanoparticles on growth advancement, hematological parameters, and nutrients digestibility of L. rohita fingerlings.

ABSTRACT
Purpose: To evaluate the use of Scheimpflug tomography in corneal densitometry (CD) in comparing the stages of keratoconic eyes. Methods: Keratoconic (KC) corneas (stages 1–3 classified according to the topographic parameters) were examined using the Scheimpflug tomographer (Pentacam, Oculus) using the CD software. CD was measured over three different depths (anterior stromal layer [120 ?m], posterior stromal layer [60 ?m], and middle stromal layer between these two layers), and concentric annular zones (0.0 to 2.0, 2.0 to 6.0, 6.0 to 10.0, and 10.0 to 12.0 mm diameter area). Results: The study participants were divided into three groups: keratoconus (KC) stage 1 (KC1) with 64 participants, keratoconus stage 2 (KC2) with 29 participants, and keratoconus stage 3 (KC3) with 36 participants. Comparing CD of all three layers (anterior, central, and posterior) of the cornea over different circular annuli (0–2, 2–6, 6–10, and 10–12 mm) revealed a significant difference in the 6–10 mm annulus between all groups and in all layers (P = 0.3, 0.2, and 0.2, respectively). Area under curve (AUC) was done. It revealed that the central layer showed the highest specificity (93.8%) in comparing KC1 and KC2, whereas CD in the anterior layer between KC2 and KC3 had the highest specificity (86.2%). Conclusion: CD showed increased values in the anterior corneal layer and in the annulus 6–10 mm more than other locations in all stages of KC

ABSTRACT
BACKGROUND: Jasmonic acid (JA) is a signal transducer molecule that plays an important role in plant development and stress response; it can also efficiently stimulate secondary metabolism in plant cells. RESULTS: RNA-Seq technology was applied to identify differentially expressed genes and study the time course of gene expression in Rhazya stricta in response to JA. Of more than 288 million total reads, approximately 27% were mapped to genes in the reference genome. Genes involved during the secondary metabolite pathways were up- or downregulated when treated with JA in R. stricta. Functional annotation and pathway analysis of all up- and downregulated genes identified many biological processes and molecular functions. Jasmonic acid biosynthetic, cell wall organization, and chlorophyll metabolic processes were upregulated at days 2, 6, and 12, respectively. Similarly, the molecular functions of calcium-transporting ATPase activity, ADP binding, and protein kinase activity were also upregulated at days 2, 6, and 12, respectively. Time-dependent transcriptional gene expression analysis showed that JA can induce signaling in the phenylpropanoid and aromatic acid pathways. These pathways are responsible for the production of secondary metabolites, which are essential for the development and environmental defense mechanism of R. stricta during stress conditions. CONCLUSIONS: Our results suggested that genes involved in flavonoid biosynthesis and aromatic acid synthesis pathways were upregulated during JA stress. However, monoterpenoid indole alkaloid (MIA) was unaffected by JA treatment. Hence, we can postulate that JA plays an important role in R. stricta during plant development and environmental stress conditions.

@#The use of natural products for disease control is a promising approach to solving the problem of drug resistance. The aim of the research reported here was to evaluate the fasciolicidal and anti-Clostridium novyi type B activities of propolis administered orally to sheep infected with Fasciola gigantica and C. novyi type B. Sheep infected with both pathogens were divided into two groups: an infected treated group and an infected non-treated group. The treatment was oral administration of 50 mg propolis extract/kg daily for 15 days. The body weight of the sheep, fecal egg counts of F. gigantica, serum levels of F. gigantica IgG, concentrations of cytokines (IL-2, IL-10, and IL-17), and bacterial counts of C. novyi were evaluated. Following treatment, the sheep had increased body weight and a significant decrease in the egg count, which was reduced by 54.54% at 15 days post treatment. The level of anti- Fasciola IgG increased, whereas levels of IL-2, IL-10, and IL-17 decreased in propolistreated sheep. Treatment of sheep with propolis produced a significant reduction in fecal count of C. novyi, from 8 × 109 to 3 × 103 colony units per gram at 15 days post treatment. This research highlights the therapeutic potential of Egyptian propolis extract as a treatment against F. gigantica and C. novyi type B infections, and investigated its mode of action through its effect on some cellular and humoral responses in sheep with both infections.
ABSTRACT
@# The present study was conducted to detect the therapeutic effect of Moringa oleifera and Thymus vulgaris oils on hepatic coccidiosis in experimentally infected rabbits. Also, immunomodulatory effect of the two oils was detected. Twenty-four Newzealand rabbits were used in this study and divided into 4 groups; healthy rabbits, experimentally infected rabbits with Eimeria stiedae oocysts, and two infected treated groups (one with moringa (200 mg/kg) and the other with thyme (500 mg/kg) oils). The results showed highly significant reduction in oocysts shedding (P<0.001 and P<0.05) in the two infected and treated rabbits than the infected non-treated rabbits in almost all days post infection (PI). Thyme oil was more potent and stopped oocysts shedding earlier at the day 34 PI compared to moringa oil at the day 41 PI. Microscopically, there was a damage in the oocysts shed by treated rabbits. Macroscopically, the livers of thyme oil treated rabbits showed more enhancement with protection percentage 75% than those treated with moringa oil in which protection percentage was 55%. The highest titer of antibodies was detected in moringa oil treated rabbits. It was concluded that both moringa and thyme oils had an anti-coccidial effect with thyme oil superiority. So, thyme oil could be useful as an alternative product for the control of rabbit coccidiosis.

ABSTRACT
@#Introduction: Proximal femur resection and endoprosthetic reconstruction is the preferred treatment for extensive bony destruction and pathological fractures. Due to the relatively high cost of endoprosthesis, we adopted the modified unipolar hemiarthroplasty (MUH) for reconstruction when the mode of treatment was for palliation. Materials and Methods:This is a retrospective case study of six patients, who had bone and multi-organs metastases with extensive proximal femur involvement with pathologic fractures who underwent resection and MUH reconstruction during the period 2013 to 2017. All patients were classified as Group B / C based on Scandinavian Sarcoma Group survival scoring, with estimated survival of maximum six months. The basic MUH construct consisted of AustinMoore prosthesis which was secured to a Küntscher nail using cerclage wire and cemented into the femoral canal. Subsequently, the whole length of the prosthesis which remained outside the canal was coated with cement. Results:The mean age was 61.8 years. The mean survival was 3.9 months, post-operation. There was no implant failure during patients’ life span; however, a third of the patients developed infection. Wheel chair ambulation was started immediately post-operation for all patients, and two patients progressed to walking frame ambulation. The total cost of each construct was below US$490 in comparison to long-stem hemiarthroplasty (roughly US$ 1700). Conclusion: Our aim was to alleviate pain, facilitate rehabilitation, ease nursing care and improve quality of life for metastatic bone disease patients until end of life. MUH for the treatment of pathological fracture in proximal femoral metastases is a feasible palliative surgical modality in resource-limited settings.
ABSTRACT
Background:The menstrual disorders are the most common gynecologic illnesses. These disorders can negatively affect the quality of the adult females’ lives. This study aimed to determine the prevalence and the nature of menstrual disorders among women in Jeddah to find its relation to pain and to identify what is normal and acceptable. Methods: A cross-sectional survey was conducted from Jan 23 to 31, 2018 in Jeddah, KSA among 303 female. Frequencies and Chi-square test were used in data analysis by SPSS software. Result: This study enrolled 303 participants with a mean of 26.8 ± 6.8 years and a range of 16-52 years. The mean age at menarche was 12.9 years. The majority of the participants had a regular period (69.6%). (8.3%) had polymenorrhea and (2.6%) had oligomenorrhea. The menstrual flow length of the most women was ranged from 3 to 7 days (80.9%). The prevalence of menorrhagia was (19.1%) while hypomenorrhea was (19.5%). (74.3%) of the participants reported that they experienced moderate to severe dysmenorrhea and (49.2%) of them their daily activities were affected by the pain. (58.4%) of the responders that reported menstrual disorders used medication for symptom relief and 108 of them indulged in self-medication. (89.4%) admitted they have undergone psychological changes the few days before the menses. Conclusion: Dysmenorrhea was the commonest reported menstrual disorder (74.3%) followed by irregular menstruation (30.4%). The high prevalence of non-expert treatment in the respondents for relieving symptoms confirms the need for awareness creation, emphasizing the dangers of the possibilities of the presence of other harmful differential health disorders.
ABSTRACT
@#Sjörgren’s syndrome is an uncommon chronic autoimmune disorder that affects exocrine glands. Sialolithiasis is an obstructive salivary gland disease which is also uncommon in the parotid salivary gland. The existing literature has documented the occurrence of multiple calcifications within the parenchyma of the parotid glands in patients with Sjörgren’s syndrome. This report describes the first case of right parotid duct solitary sialolith formation in a 64 year old female patient with Sjörgren’s syndrome. Whether the salivary stone encountered in this case represents an oral manifestation of Sjörgren’s syndrome or is just a co-incidental finding was discussed.

The selected cases were between 5 to 60 years of age. The samples were divided into 3 different age groups (A: 05-15 years, B: 16-35 years, C: 36- 60 years) to observe the variations in number of medullary pyramid of kidney in different age groups. Results: Among three groups, highly significant (<0.001) differences were found statistically in the number of medullary pyramid. Conclusion: There were changes in the number of medullary pyramid of kidney in different age groups.
ABSTRACT
To determine the two-dimensional and doppler sonographic features that best allow differentiation between malignant and benign adnexal masses, besides develop a new scoring system enable more accurate diagnosis with these features. A cross sectional prospective study was conducted on patients scheduled for surgery due to presence of adnexal masses at Women's Health Hospital, Assiut, Egypt between October 2012 and October 2013. All patients were evaluated by 2D ultrasound for morphological features of the masses aided by doppler examination of their vessels. The final diagnosis was based on histopathological reports used as gold standard. One hundred forty-six patients were recruited, 104 with benign masses, 42 with malignant masses. Features that allowed statistically significant discrimination of benignity from malignancy were; volume of mass, type of mass, presence and thickness of septae, presence and length of papillary projections, location of vessels at colour Doppler and colour score. A scoring formula was supposed combined those features together to develop a new scoring system; Assiut Scoring System [ASS]. The cut-off score with the highest accuracy in detection of malignancy had a sensitivity of 93.5% and specificity of '92.2%. Assiut Scoring System; a multiparameter scoring that use four 2D ultrasound and two doppler features, has a high sensitivity and specificity for prediction of malignancy in adnexal masses

The Saudi Thoracic Society [STS] launched the Saudi Initiative for Chronic Airway Diseases [SICAD] to develop a guideline for the diagnosis and management of chronic obstructive pulmonary disease [COPD]. This guideline is primarily aimed for internists and general practitioners. Though there is scanty epidemiological data related to COPD, the SICAD panel believes that COPD prevalence is increasing in Saudi Arabia due to increasing prevalence of tobacco smoking among men and women. To overcome the issue of underutilization of spirometry for diagnosing COPD, handheld spirometry is recommended to screen individuals at risk for COPD. A unique feature about this guideline is the simplified practical approach to classify COPD into three classes based on the symptoms as per COPD Assessment Test [CAT] and the risk of exacerbations and hospitalization. Those patients with low risk of exacerbation [<2 in the past year] can be classified as either Class I when they have less symptoms [CAT < 10] or Class II when they have more symptoms [CAT >/= 10]. High-risk COPD patients, as manifested with >/= 2 exacerbation or hospitalization in the past year irrespective of the baseline symptoms, are classified as Class III. Class I and II patients require bronchodilators for symptom relief, while Class III patients are recommended to use medications that reduce the risks of exacerbations. The guideline recommends screening for co-morbidities and suggests a comprehensive management approach including pulmonary rehabilitation for those with a CAT score >/= 10. The article also discusses the diagnosis and management of acute exacerbations in COPD.
