The functional anatomy of hip abductors

The gluteal region was dissected in 18 adult cadavers. The attachments, directions, and orientations of the fibres of the tensor fasciae latae, gluteus medius, and gluteus minimus muscles were noted. The gluteus medius was found to be formed of three distinct parts, while the gluteus minimus was formed of two parts only; each part of these muscles had its separate innervations from the superior gluteal nerve. The tensor fasciae latae muscle arose from the anterior part of the outer lip of the iliac crest and was attached to the iliotibial tract slightly below and in front of the greater trochanter. The direction of the fibres of the anterior and middle parts of the gluteus medius and the anterior part of the gluteus minimus suggested that they have vertical pull and initiate abduction which is then completed by the tensor fasciae latae. The function of the posterior parts of the gluteus medius and minimus, being parallel to the neck of the femur, would be stabilization of the femoral head in the acetabulum during the different stages of the gait cycle. By resolving the line of action of the tensor fasciae latae muscle, it was found to help the muscle to fix the hip and femur together during the stance phase and to counteract the weight of the body during standing position

Anatomical localisation of the marginal mandibular branch of the facial nerve

The marginal mandibular nerve was studied post mortem in 50 human subjects. The nerve was found to be presented by one branch (32%), two branches (40%) and three branches (28%). The relationship of the nerve to the lower border of the mandible was variable: it was either totally above the lower border of the mandible (28%), below the mandible (44%) or in 28% of cases lying above and below it. The branch which lay below the lower border of the mandible crossed it opposite the masseter muscle or opposite the facial artery or else anterior to the facial artery. The branches which lay above the lower border of the mandible were always deep into the superficial layer of the parotid fascia, while below the mandible all the branches ran intrafascially. The termination of the nerve was always deep to the muscles of the lower lip. The results of the present study were discussed and correlated with the results of other authors from the anatomical and surgical points of view. It is concluded that the lower border of the mandible can serve as an important landmark to help avoid injury to the nerve; above it a subplatysmal flap is satisfactory but below it a subfascial flap is much safer

Origin of profunda femoris artery and its circumflex femoral branches: anatomical variations and clinical significance

Background: Knowledge of the anatomical variations of the profunda femoris artery and its circumflex branches is important during angiographic diagnostic procedures as well as during performing surgery in the femoral region. The aim of this study was to examine the original sites, distances and variations of the profunda femoris artery and its circumflex branches. Materials and methods: The study was conducted in the Department of Anatomy, Faculty of Medicine, King Abdulaziz University from October, 2011 to May, 2013 after the approval of the medical ethical committee. Dissections of 90 femoral triangles of 25 male and 20 female adult human cadavers were performed to demonstrate the origin and distribution of the profunda femoris artery and its circumflex branches. Results: The profunda femoris artery mostly originated from the posterolateral aspect of the femoral artery in 42% of male limbs and in 42.5% of female limbs, from the posterior side in 24% of male and 27.5% of female limbs, from the lateral side in 20% of males and female limbs and from the posteromedial aspect in 14% of male limbs and in 7.5% of female limbs. The mean distance of origin of profunda femoris artery from the midpoint of inguinal ligament was 51.5 ± 1.9 mm in right male, 49.7 ± 1.9 mm in left male, 48.5 ± 2.2 mm in right female and 48.9 ± 2.2 mm in left female limbs. The medial and lateral circumflex arteries originated mostly from the profunda femoris artery (60% in males; 57.7% in females) at a mean distance of 18.6 ± 2.1 mm and 20.2 ± 2.2 mm in right male, 19.6 ± 1.9 mm and 22.5 ± 2.3 mm in left male, 18.8 ± 2.7 mm and 21 ± 2.6 mm in right female and 19.1 ± 2.1 mm and 21.7 ± 2.6 mm in left female limbs, respectively. The original incidence of the medial and lateral circumflex femoral arteries from the femoral artery including the common trunk was 40% in male and 42.3% in female limbs. Conclusions: Awareness of the original sites and distances of the profunda femoris artery and its circumflex femoral branches will allow the surgeon to define the vascular pattern before performing any invasive procedure and to avoid unexpected iatrogenic injuries

THE INFLUENCE OF GENISTEIN IMPLANTATION ON OFFSPRING SEX RATIOS AND THEIR RELATION TO ESTROGEN LEVELS IN THE BLOOD OF IRAQI CHICKENS

This study was carried out at the Poultry Research Station / Agricultural Research Department / Ministry of Agriculture, to investigate the effects of implanting genistein (GE) for the period of 1/February/2021 to 16/August/2021. into Iraqi local chickens at various ages on primary (PSF) and secondary (SSF) sex ratios of female, fertility (FE), and hatchability (HA) traits. At the age of 12 weeks, 100 hens and 20 roosters of Iraqi local chickens from the Poultry Research Station were used in this study. After numbering the hens, the birds were housed in individual cages and divided into four treatments (each with 25 chickens) as follows: T1: none implantation; T2, T3, and T4: implantation of 10 mg GE /kg weight at 14, 18, and 22 weeks of age, respectively. The experiment was divided into three periods, each for 28 weeks, and then rated according to the overall average and all of the traits studied. The results showed that implanting GE into hens had a positive influence on FE, PSF, SSF, and estrogen level (ES), especially at 18 weeks of age. There were also significant correlations between traits and ES in hens’ blood. It was also shown that the regression of most traits on ES is first order linear. As a result, it can be concluded that GE has a positive effect on ES, PSF, SSF, with the possibility of predicting sex ratios and sex offspring based on estrogen levels in the blood, and that implantation at 18 weeks of age has produced great results

The infection with HBV and HCV and their relationship to ABO blood group among blood donors

Background: Hepatitis B virus (HBV) and C virus (HCV) known to be transmitted through blood and blood products and has been implicated as a major cause of chronic liver disease and hepatocellular carcinoma worldwide. Objective: This study aim to detect the relationship between the HBV and HCV infections with ABO blood groups and age of blood donor in Al- Ramadi city. Patients & Methods: We conducted Hepatitis B surface antigen test strip (ACON Laboratories) (USA) and HCVAb, as step to detect the infections among blood donors at the laboratories for central blood bank in Alanbar health directory, M.O.H. The results of this study were analyzed statistically using the T-test to find the significance of probability level according to SPSS ver12 program. (P) Value < 0.05 were considered significant. Results: Among (430) volunteer blood donors, there were 71(16.511%) positive for HBs Ag and 12(2.790%) for HCVAb. Hepatitis B and C infections were significantly associated with blood group of the donors; percentage of HBs Ag and HCVAb were found to be higher in donors who has blood group O and lowest in blood group AB donors, while the distribution of Rh in hepatitis infected donors was higher among Rh positive donors. HCV infections show a high percentage at age group (26–35) years old, while the percentage of HBV infections increase with progress of age group among blood donors. Conclusion: There were a significant association between blood group of donors and hepatitis infections and the infections of HCV increase among (26-35) years old blood donors while the HBV infections increase with progress of age groups

Effect of Dietary Linseed on Egg Quality of Laying Quail

Abstract: This experiment was performed to investigate the effect of dietary supplementation with linseed on egg quality of laying quail. A total of 320 Japanese quail (Coturnix coturnix japonica) 9-wk old were allocated to 4 treatment groups with 4 replicates containing 20 quail each. Birds were fed commercial diet containing 0% (C), 2% (T1), 4% (T2) or 6% (T3) linseed. Birds received water and diet ad libitum during the total period of experiment. Egg quality characteristics were monitored over 3 consecutive 21-d periods. Egg quality criteria involved in this experiment were egg weight, yolk diameter, yolk height, yolk weight, albumen height, albumen weight, shell weight, shell thickness, Haugh unit, albumen percentage, yolk percentage and shell percentage. Results revealed that supplementing diet of laying quail with linseed resulted in significant increase in total means of egg weight, yolk diameter, albumen height, shell thickness, Haugh unit, albumen percentage and albumen weight. Total means of shell weight and yolk percentage were not significantly (p&gt;0.05) different from quails consuming 0, 2, 4 or 6% linseed; However, total mean of shell percentage was reduced (p&lt;0.05) in laying quails fed linseed when compared to control group. In conclusion, Feeding laying quails with different levels of linseed (2%, 4%, or 6%) caused significant improvement as regards most of egg quality parameters included in this experiment. Therefore, adding linseed to the ration could be used as a good tool for improving productive performance of Japanese quail

Activation of Type 1 Cannabinoid Receptor (CB1R) promotes neurogenesis in murine subventricular zone cell cultures

The endocannabinoid system has been implicated in the modulation of adult neurogenesis. Here, we describe the effect of type 1 cannabinoid receptor (CB1R) activation on self-renewal, proliferation and neuronal differentiation in mouse neonatal subventricular zone (SVZ) stem/progenitor cell cultures. Expression of CB1R was detected in SVZ-derived immature cells (Nestin-positive), neurons and astrocytes. Stimulation of the CB1R by (R)-(+)-Methanandamide (R-m-AEA) increased self-renewal of SVZ cells, as assessed by counting the number of secondary neurospheres and the number of Sox2+/+ cell pairs, an effect blocked by Notch pathway inhibition. Moreover, R-m-AEA treatment for 48 h, increased proliferation as assessed by BrdU incorporation assay, an effect mediated by activation of MAPK-ERK and AKT pathways. Surprisingly, stimulation of CB1R by R-m-AEA also promoted neuronal differentiation (without affecting glial differentiation), at 7 days, as shown by counting the number of NeuN-positive neurons in the cultures. Moreover, by monitoring intracellular calcium concentrations ([Ca2+](i)) in single cells following KCl and histamine stimuli, a method that allows the functional evaluation of neuronal differentiation, we observed an increase in neuronal-like cells. This proneurogenic effect was blocked when SVZ cells were co-incubated with R-m-AEA and the CB1R antagonist AM 251, for 7 days, thus indicating that this effect involves CB1R activation. In accordance with an effect on neuronal differentiation and maturation, R-m-AEA also increased neurite growth, as evaluated by quantifying and measuring the number of MAP2-positive processes. Taken together, these results demonstrate that CB1R activation induces proliferation, self-renewal and neuronal differentiation from mouse neonatal SVZ cell cultures.Fundacao para a Ciencia e a Tecnologia - Portugal [POCTI/SAU-NEU/68465/2006, PTDC/SAU-NEU/104415/2008, PTDC/SAU-NEU/101783/2008, POCTI/SAU-NEU/110838/2009]; Fundacao Calouste Gulbenkian [96542]; Fundacao para a Ciencia e Tecnologiainfo:eu-repo/semantics/publishedVersio

The three main monotheistic religions and gm food technology: an overview of perspectives

Abstract Background Public acceptance of genetically modified crops is partly rooted in religious views. However, the views of different religions and their potential influence on consumers' decisions have not been systematically examined and summarized in a brief overview. We review the positions of the Judaism, Islam and Christianity – the three major monotheistic religions to which more than 55% of humanity adheres to – on the controversies aroused by GM technology. Discussion The article establishes that there is no overarching consensus within the three religions. Overall, however, it appears that mainstream theology in all three religions increasingly tends towards acceptance of GM technology per se, on performing GM research, and on consumption of GM foods. These more liberal approaches, however, are predicated on there being rigorous scientific, ethical and regulatory scrutiny of research and development of such products, and that these products are properly labeled. Summary We conclude that there are several other interests competing with the influence exerted on consumers by religion. These include the media, environmental activists, scientists and the food industry, all of which function as sources of information and shapers of perception for consumers
