The role of sucrose in maintaining pollen viability and germinability in Corylus avellana L.: a possible strategy to cope with climate variability.

In this work, we propose a possible correlation between carbohydrate content in hazelnut pollen (wild type) and viability/germinability, also in a perspective of adaptation to climate variability. Samples from four different cultivation fields in Italy showed values of pollen viability characterized by high levels, ranging between 77.3 and 98.

ACE Inhibitors and Angiotensin Receptor Blockers for the Primary and Secondary Prevention of Cardiovascular Outcomes: Recommendations from the 2024 Egyptian Cardiology Expert Consensus in Collaboration with the CVREP Foundation.

Introduction: The renin-angiotensin-aldosterone system (RAAS) plays a pivotal role in regulating blood pressure (BP), with dysregulation of RAAS resulting in hypertension and potentially heart failure (HF), myocardial infarction (MI), cardio-renal syndrome, and stroke. RAAS inhibitors, such as angiotensin-converting enzyme inhibitors (ACEis) and angiotensin receptor blockers (ARBs), have advantages beyond BP control. However, differences between these two drug classes need to be considered when choosing a therapy for preventing cardiovascular events.

Amino-acid PET as a prognostic tool after post Stupp protocol temozolomide therapy in high-grade glioma patients.

Purpose: This study aimed to evaluate the prognostic performance of amino-acid PET in high-grade gliomas (HGG) patients at the time of temozolomide (TMZ) treatment discontinuation, after the Stupp protocol.

Methods: The analysis included consecutive HGG patients with dynamic [18F]FDOPA PET imaging within 3 months of the end of TMZ therapy, post-Stupp protocol. Static and dynamic PET parameters, responses to RANO criteria for MRI and clinical and histo-molecular factors were correlated to progression-free (PFS).

Idiopathic eosinophilic cholecystitis with cholelithiasis: Two rare cases report.

Introduction And Importance: Eosinophilic cholecystitis is an unusual condition in which more than 90 % of the inflammatory infiltrate in the gallbladder wall is comprised of eosinophils. The pathogenesis of eosinophilic cholecystitis is still unknown, but in some cases, it is related to hyper-eosinophilic syndrome, parasitosis, infections, and drugs.

Case Presentation: We described two cases in which a woman aged 27 years and a man aged 30 years presented with acute and chronic cholecystitis symptoms, respectively.

Do the Most Attractive Faces of Patients With Class II Division 1 Malocclusion Differ From Those With the Least Attractive Faces in Terms of Angular and Proportional Measurements Assessed on Frontal and Lateral Photographs?

Background This study investigated the facial angles and proportions affecting facial aesthetics in patients with skeletal class II division 1 malocclusion between those labeled the most attractive and least attractive in each gender. Methodology The study sample included pretreatment extraoral photographs of 60 patients (30 males and 30 females) with skeletal class II division 1 malocclusion according to the ANB angle aged between 18 and 21 years. A panel of 240 laypersons (aged 20-25 years; the average age of 22.

Evaluation of Novel Topical Camel Whey Protein Gel for the Treatment of Recurrent Aphthous Stomatitis: Randomized Clinical Study.

Aim: The aim of this article is to evaluate the topical effect of camel whey protein (CWP) on the healing of recurrent aphthous stomatitis (RAS) and the serum levels of interleukin (IL)-1, IL-6, and tumor necrosis factor (TNF)-α.

Materials And Methods: Forty patients with minor RAS were randomly assigned into control and study groups. The control group applied placebo methylcellulose gel topically over the aphthous ulcer, whereas the study group used CWP dissolved in methylcellulose gel topically over the aphthous ulcer.

QRS Duration as a Predictor of Left Ventricular Outflow Tract Velocity Time Integral in Patient with Cardiac Resynchronization Therapy.

Background: Cardiac resynchronization therapy (CRT) has a morbidity and mortality benefits in moderate to severe heart failure. It reduces mortality and hospitalization and improves cardiac function. It can be used according to the European guidelines in severely depressed left ventricular ejection fraction (i.

Early Pulmonary Vein Conduction Recovery after Catheter Ablation of Atrial Fibrillation.

Background: Pulmonary vein electrical isolation (PVI) is an effective treatment for atrial fibrillation (AF). However, recurrence of pulmonary vein (PV) conduction after ablation may limit long-term success. Early identification and treatment of acute PV conduction recovery during initial ablation may have an impact on subsequent clinical results.

Local Intracoronary Infusion of Glycoprotein IIb/IIIa Inhibitors via a Perfusion Catheter versus Intracoronary Guiding Catheter Injection during Primary Percutaneous Coronary Intervention: A Pilot Observational Study.

Background: Glycoprotein IIb IIIa inhibitors improved short- and long-term outcome when added to primary percutaneous coronary intervention (PPCI) in patients with ST-segment-elevation myocardial infarction (STEMI). We hypothesized that intracoronary eptifibatide infusion via a perfusion catheter improves angiographic and clinical outcome of patients with STEMI undergoing PPCI, versus conventional intracoronary bolus injection.

Methods: Prospectively, we enrolled 80 patients with acute STEMI and thrombolysis in myocardial infarction (TIMI) thrombus grade ≥ 2.

Silibinin Improves the Effects of Methotrexate in Patients with Active Rheumatoid Arthritis: Pilot Clinical Study.

Objectives: Our study sought to evaluate the effects of silibinin in patients with active rheumatoid arthritis (RA) treated with methotrexate (MTX).

Methods: We conducted a randomized multi-center, double-blind, placebo-controlled clinical trial over a 16-week treatment period at the Al-Sader and Baghdad Teaching Hospitals in Najaf and Baghdad, respectively. A total of 60 patients (30 of each sex) with active RA, already maintained on 12 mg MTX weekly for at least three consecutive months, were included in the study.

Intracoronary versus intravenous adenosine-induced maximal coronary hyperemia for fractional flow reserve measurements.

Background: Maximal hyperemia is the critical prerequisite for fractional flow reserve (FFR) assessment. Despite intravenous (IV) adenosine currently being the recommended approach, intracoronary (IC) administration of adenosine constitutes a valuable alternative in everyday practice. However, it is surprisingly unclear which IC strategy allows the achievement of FFR values that are comparable to IV adenosine.

A simplified technique for the restoration of severely mutilated primary anterior teeth.

The restoration of severely carious primary anterior teeth is a challenge to the pediatric dentist. The introduction of new materials and technologies makes re-evaluation of existing treatment philosophies necessary. A technique involving the placement of an omega shaped stainless steel wire extension into the entrance of the root canal prior to restoring the crown with a compomer material is described.

Histology of vitreous in its gel and fluid forms.

Low- and high-power microscopic examination of just-dried (without flame) fresh smears of gel, semi-gel, and fluid human and rabbit vitreous without stain showed that solid gel vitreous is composed of two types of transparent network, i.e., thick fibers in meshes of which there is another fine fibril network and both types of fluid vitreous, the fiber and fibril networks, show stages in transformation to transparent granules; this is why fluid vitreous remains transparent.

Chemical vitrectomy: change of solid gel vitreous to sol for vitrectomy by changing pH of vitreous toward the slight acid side.

Solid gel vitreous was changed to sol by changing the pH of the vitreous toward the slightly acid side by using diluted acetic acid of various weak concentrations. For human and rabbit vitreous in vitro, the gel sol change with regard to time in respect to concentration of the weak acid was noted. Rabbit eyes in vivo were used.

Lindner posterior vitreous fistula with senile cataract extraction for quick reformation of anterior chamber: indications, technique, and results.

Pars plana partial vitrectomy using Lindner posterior vitreous fistula was prophylactically used with senile cataract extraction in cases known to be liable for nonreformation of anterior chamber and gelly vitreous with perfect results as regards postoperative maintenance of anterior chamber aphakic depth. The combined operation is indicated in cases (1) if the other eye was lost through nonreformation of anterior chamber after a perfect senile cataract extraction; and (2) in very old patients with very shallow anterior chamber especially when there are other senile ocular changes such as flatter, thinner cornea, tendency for uveal vascular engorgement and exudations (after hypotony of operation), and bad wound healing. This is especially true in small hypermetropic eyes with small cornea.
