Post-extraction volumetric analysis of alveolar ridge contour using subepithelial connective tissue graft in esthetic zone: a randomized controlled clinical trial.

Objectives: The aim of this randomized clinical trial was to assess the alveolar ridge contour after soft tissue augmentation using subepithelial connective tissue graft (SCTG) buccal to fresh extraction sockets in patients with thin buccal bone, versus minimally-traumatic extraction followed by spontaneous healing solely.

Materials And Methods: Forty non-restorable maxillary teeth in the esthetic zone were randomly assigned into two groups: minimally-traumatic extraction with SCTG (test) and minimally-traumatic extraction followed by spontaneous healing (control). The outcomes assessed included linear volumetric change of buccal soft tissue contour, vertical tissue loss, gingival thickness (GT), and interdental papilla (IDP) height after 6 months.

Immunohistochemical Expression of CD90, CD133, and TPM1 in Relation to Gastric Cancer and H. pylori Association.

Background: Gastric cancer (GC) is the second most common cause of cancer-related death worldwide. Multiple malignancies overexpress CD90, making it a helpful diagnostic and prognostic marker. CD133 is suggested to be related to poor prognosis in GC.

Evaluation of needling-induced autoinoculation in the management of genital warts.

Background: Genital warts caused by human papillomavirus (HPV) are one of the most common sexually transmitted infections. Long latency, lesions' multiplicity, high recurrence rate, and the tendency to malignant transformation are essential challenges during management. Traditional treatment modalities are known to be lesion-directed while intralesional immunotherapy was introduced to act beyond individual lesions and to confront the previous challenges through injection of known antigens, such as measles, mumps and rubella (MMR) vaccine, to stimulate the immune system against HPV.

The herbal preparation STW 5 affects serotonergic pathways in the brain and colon as well as stress parameters in experimental irritable bowel syndrome.

Background: Exposure to stress has been related to disturbance in 5-hydroxytryptamine (5-HT) signaling in the brain-gut axis and is considered as a major predisposing factor for the development of irritable bowel syndrome (IBS). The present study aimed to investigate the possible involvement of 5-HT and some other stress-related parameters in the effectiveness of STW 5 against stress-induced IBS.

Methods: Rats were subjected to restraint stress (RS) for 1 h/day for 14 consecutive days to induce IBS-like symptoms and were given STW 5 orally at the same time.

Combining Bevacizumab with Knocked-Down β-Catenin Reduces VEGF-A and Slug mRNA in HepG2 but not in Caco-2 Cell Lines.

Background: Bevacizumab (Bev) resistance is hypothesized to be overcome by combining inhibitors of other signalling pathways.

Objective: We aimed to study the effect of combining Bev with knocked down β-catenin (Bev-β-cat-siRNA) on the expression of VEGF-A, Slug, NFκB, and its two target genes, c-Flip and FasR, in HepG2. Expression of VEGF-A and Slug was also studied in Caco-2 cells.

Veno-arterial rail and over the wire technique for atrial septal defect closure in a patient with interrupted inferior venae cava.

Transcatheter closure of secundum atrial septal defect (ASD II) is considered the treatment of choice when anatomically suitable and clinically indicated. This is routinely done through the inferior vena cava via a femoral venous approach; however, certain anatomical anomalies, such as congenital interruption of inferior vena cava with azygos continuation, render the delivery of the device either difficult or not possible. When this anomaly is also associated with dextrocardia, the technical challenge increases further due to the unusual orientation of the interatrial septum.

Comparison of the early cardiac electromechanical remodeling following transcatheter and surgical secundum atrial septal defect closure in adults.

Background: Secundum atrial septal defect (ASD) closure leads to electrical and mechanical remodeling that occurs early after shunt disappearance. The relationship between electromechanical remodeling using electrocardiogram (ECG) and cardiac magnetic resonance (CMR) after percutaneous and surgical closure has not yet been recorded in prospective studies.

Objective: We thought to study right atrium (RA) and right ventricle (RV) changes by CMR 3 months after transcatheter and surgical closure and their comparison with electrical remodeling by ECG.

PPAR agonists as effective adjuvants for COVID-19 vaccines, by modifying immunogenetics: a review of literature.

Background: Several coronavirus vaccine have been fast-tracked to halt the pandemic, the usage of immune adjuvants that can boost immunological memory has come up to the surface. This is particularly of importance in view of the rates of failure of seroconversion and re-infection after COVID-19 infection, which could make the vaccine role and response debatable. Peroxisome proliferator-activated receptors (PPARs) have an established immune-modulatory role, but their effects as adjuvants to vaccination have not been explored to date.

Multidisciplinary assessment of patients with ischemic stroke, the structure of a stroke team, and first Egyptian experience in adults undergoing transcatheter PFO closure for PFO-related stroke.

Background: Patent foramen ovale closure in the setting of stroke was debatable until the recent data from the long-term follow-up of multiple randomized control trials. These recent data have led to increase the number of the procedure worldwide. To our knowledge, there was no previous formal structured program in Egypt between cardiologists and neurologists for investigation and management of patients with cryptogenic stroke.

The potential use of lactate blockers for the prevention of COVID-19 worst outcome, insights from exercise immunology.

Following the decline in Physical Activity (PA) due to COVID-19 restrictions in the form of government mandated lockdowns and closures of public spaces, the modulatory effect of physical exercise on immunity is being heavily revisited. In an attempt to comprehend the wide discrepancy in patient response to COVID-19 and the factors that potentially modulate it, we summarize the findings relating PA to inflammation and immunity. A distinction is drawn between moderate intensity and high intensity physical exercise based on the high lactate production observed in the latter.
