Does seasonal variation affect the neuroimmune system? A retrospective [C]PBR28 PET study in healthy individuals.

Introduction: The neuroimmune system performs a wide range of functions in the brain and the central nervous system. The microglial translocator protein (TSPO) has an established role as a cell marker in identification of the neuroimmune system. Previously, human studies have shown TSPO differences in neuropsychiatric disorders.

The Virtual Surgical Management of Facial Fibrous Dysplasia.

Purpose: Fibrous dysplasia (FD) is a benign condition, which is characterized by the replacement of normal bone with fibrous tissue and the deposition of woven bone in an irregular manner. Surgical resection, careful corrective osteotomies as debulking, and recontouring procedures are frequently performed, but can be complicated by postoperative regrowth of the lesion. The main aim of this study was to introduce a computer-guided technique for a predetermined technique of bone contouring of craniofacial FD involving the facial bones.

A Split-Mouth Study to Assess the Effect of Implant Surface Roughness on Implant Treatment Outcome After 5 Years.

The aim of current split-mouth study was to compare the implant treatment outcomes of hybrid-surface implants (minimally rough implant collar and moderately rough body) with moderately rough implants after 5 years in patients with a bar-supported mandibular overdenture. Fully edentulous patients were enrolled, and each patient received two implants: one moderately rough and one hybrid-surface implant. A total of 18 patients with 36 implants attended the 5-year recall, and the implant survival rate was 100%.

Delayed complex fronto-zygomatico-orbital reconstruction using patient specific 3D printed implants; A report of three complex cases - A short communication.

Purpose: To demonstrate use of patient specific implants (PSIs) in the reconstruction of significant facial skeletal defects. Polyamide 12 implants were used to achieve good symmetric results with great projection and contours and minimal morbidity, all of which would not be predictably achievable with other reconstructive options.

Methods: Using a retrospective study design, three patients who had significant facial skeletal defects affecting the zygomaticomaxillary complex, frontal bone and also having an orbital component were used as subjects.

Prevalence of Anemia Among Children and Adolescents in Rural Area of Khulais in Saudi Arabia.

Introduction The decreased absolute circulating red blood cell count or the inability of red blood cells to meet physiological needs is called anemia. Anemia can affect mental health, learning capacity, and the ability to concentrate. The present study aimed to assess the prevalence of anemia among children and adolescents living in the rural areas of Khulais, Saudi Arabia.

Reconstruction of Cranial Bone Defects Using Polyamide 12 Patient-Specific Implant: Long Term Follow Up.

The main objective of this study was to evaluate the use of patient-specific polyamide 12 implants in cranial bone defect reconstruction.Ten patients who underwent prior decompression craniectomy were selected for the current study. Skull scanning by computerized tomography was performed and used to make virtual planning of the implants to be transformed into physical implant using selective laser sintering.

Percutaneous Coronary Intervention Vs Coronary Artery Bypass Surgery for Unprotected Left Main Coronary Disease: G-LM Registry.

Coronary artery bypass surgery (CABG) has been the standard of care for revascularization for patients with obstructive unprotected left main coronary disease (ULMCA). There have been multiple randomized and registry data demonstrating the technical and clinical efficacy of PCI in certain patients with ULMCA. The purpose of this study is to evaluate clinical outcomes of ULMCA PCI as compared to CABG in patients requiring revascularization in three Gulf countries.

Monitoring of Antimicrobial Susceptibility of Bacteria Isolated from Poultry Farms from 2014 to 2018.

The current situation of antibiotic resistance of most bacterial pathogens was a threat to the poultry and public health with increasing economic losses. Regarding this problem, monitoring of the circulating microorganisms occurred with the antibiotic resistance profile. A total of 657 different samples from internal organs (liver, heart, lung, and yolk) and paper-lining chick boxes were collected from native chicken farms which were submitted to the Reference Laboratory for Veterinary Quality Control on Poultry Production in the period from 2014 to 2018 for the detection of , (.

Accuracy of patient-specific temporal implants using PEKK.

The main aim of this study was to evaluate the accuracy of immediate CAD/CAM reconstruction of the temporal hollowing following temporalis muscle surgery, using a patient-specific implant (PSI) PEKK model. This case series included ten patients who underwent maxillofacial reconstruction using temporalis muscle flap (TMF). The study involved the preoperative planning and fabrication of the temporal implant using virtual surgical planning software.

Impact of the left anterior descending artery wrapping around the left ventricular apex on cardiac mechanics in patients with normal coronary angiography.

Background: We examined the impact of left anterior descending (LAD) wrapping on left ventricular (LV) mechanics in patients with normal coronary angiography. Seventy-one patients with evidence of normal coronary angiography (LAD wrapping: n = 52, 73%) and LAD non-wrapping (n = 19, 27%) were included in the study. Using 2D-strain imaging, we measured LV longitudinal and circumferential (circ) strain (ε), systolic strain rate (SR), early (SR) and atrial (SR) diastolic SR, LV electromechanical dyssynchrony (TTP-SD), and LV twist and torsion in study groups.

The occurrence of disinfectant and antibiotic-resistant genes in isolated from chickens in Egypt.

Aim: This work aimed to determine the occurrence of antibiotic and disinfectant resistance genes in isolated from chickens in Egypt.

Materials And Methods: Organs (liver, lung, heart, yolk sac, and bone marrow) of 1500 chicken samples were collected from diseased chickens suffered from colibacillosis with PM findings as CRD, diarrhea and omphalitis from different governorates of Egypt as: Giza, EL-Bahira, Fayoum, El-Dakahlia, El-Ismalia, and El-Sharkia during 2015-2016. These samples were labeled and transported immediately on ice to the Reference laboratory for quality control on poultry production (RLQP).

Greater Glycaemic Response to an Oral Glucose Load in Healthy, Lean, Active and Young Chinese Adults Compared to Matched Caucasians.

There are ethnic differences recorded in glycaemic response and rates of type 2 diabetes mellitus (DM) between Chinese and Caucasian populations. Whether these differences are evident in matched healthy, lean, active, young adults is unclear. This study compares the postprandial glycaemic response of a group of Chinese participants ( = 49) with a group of similar Caucasians, ( = 48) aged 23.

Provocation of left ventricular outflow tract obstruction using nitrate inhalation in hypertrophic cardiomyopathy: Relation to electromechanical delay.

Background: Left ventricular outflow tract obstruction (LVOT) is an independent predictor of adverse outcome in hypertrophic cardiomyopathy (HCM). It is of major importance that the provocation modalities used are validated against each other.

Aim: To define the magnitude of LVOT gradients provocation during both isosorbide dinitrate (ISDN) inhalation and treadmill exercise in non-obstructive HCM and analyze the correlation to the electromechanical delay using speckle tracking.

Systolic function reserve using two-dimensional strain imaging in hypertrophic cardiomyopathy: comparison with essential hypertension.

Background: Although patients with hypertrophic cardiomyopathy (HCM) have normal ejection fractions at rest, the investigators hypothesized that these patients have differentially abnormal systolic function reserves, limiting their exercise capacity compared with patients with hypertension (HTN).

Methods: Forty patients with HCM (mean age, 39.1 ± 12 years), 20 patients with HTN with LVH, and 33 healthy individuals underwent resting and peak exercise echocardiography using two-dimensional strain imaging.

Association of deletion allele of insertion/deletion polymorphism in α2B adrenoceptor gene and hypertension with or without type 2 diabetes mellitus.

Background: Vascular α2B-adrenoreceptors have the potential to increase blood pressure by mediating vasoconstriction. A nine-nucleotide deletion in the receptor enhances vasoconstriction and exacerbates hypertension. The aim of this study was to determine the association between insertion/deletion (I/D) polymorphism of the α2B-adrenoceptor and hypertension with and without diabetes.
