Breast cancer is a communal malignant disease between Saudi females, with a popularity of 21.8%. Since binding to somatostatin receptors (SSTR) induces no immunogenicity in vivo, somatostatin analog (veldoreotide) (VELD) may be suitable for delivering anti-cancer drugs to target and bioimaging the cancer cells. This work aimed to deliver CdS/ZnS core-shell type quantum dots with carboxylic acid-functionalized (QDs-COOH) which is bioimaging and anticancer nanoparticles decorated...
This study will be a prospective, non-randomized evaluation of the Tritanium® Primary Acetabular Shell for primary total hip replacement (THR) with a cementless application in a consecutive series of patients who meet the eligibility criteria. The first 120 cases enrolled will receive the Tritanium® Primary Acetabular Shell. An additional 120 cases will receive the Tritanium® Primary Acetabular Shell with periapatite (PA), a biological coating. The success rate, defined as ...
The initial focus of the study will be on safety, sun protection factor (SPF) characterization, and substantivity (duration of protection) studies. The primary outcome of the study will be to measure the sun protection factor (SPF) of a bioadhesive nanoparticles (BNP) formulation in 20-25 healthy volunteers with fair skin.
Patients having radiotherapy to their head and neck wear an immobilisation shell to prevent patient movement and improve treatment accuracy. These shells tend to cover the face and have the potential to cause anxiety and distress in patients, particularly if they suffer with claustrophobia or a similar fear. The study will use an 'open-face' shell that does not cover the face and compare this with the investigators' current 'closed-face' shell. The investigators will obtain tre...
Silver nanoparticles are one of most nanoparticles use nowadays in the research area because it has specific physical and chemical properties, in medical fields silver nanoparticles can involve in diagnostic and treatment processes. Silver nanoparticles have antibacterial, antiviral, antifungal, antiangiogenic, antioxidant, cosmetics, antitumor, anti-inflammatory, the drug carrier, imaging, water treatment, and biosensing effects. Silver nanoparticles prepared with reducing age...
For the purposes of this study, as a core lab coordinating center, the investigators will be performing P31 MRS core lab analyses; hormone core lab analyses; lipid core lab analyses; glucose, insulin and HOMA core lab analyses; exercise stress test/Holter monitor core lab analyses; brachial artery reactivity test core lab analyses; full study data analyses for manuscript preparation and the writing and submission and publication of manuscript.
The purpose of this study is to investigate the efficacy of combined intravitreal therapy with or without prior photodynamic therapy in patients with wet age-related macular degeneration (AMD). In patients with wet AMD, a significant improvement in vision was observed after combined intravitreal therapy with or without prior photodynamic therapy. Both the pharmacological effects of the drugs and the physiological effects of the pars plana vitrectomy (posterior vitreous d...
The hypothesis is that Addition of copper or zinc nanoparticles to a dental adhesive confers antimicrobial and enzymatic degradation-resistant properties, retaining its adhesion mechanical properties and biocompatibility. To corroborate this hypothesis two groups of a dental adhesive doped with copper or zinc nanoparticles should be develop with a respective structural characterization by SEM-EDX, AFM and FTIR. This should be followed by a test of the antimicrobial activity of ...
The purpose of this study is to determine whether oral topic silver nanoparticles are effective to reduce potential pathogen microbial loads in mechanical ventilation patients.
In patients with type III or IV cholangiocarcinoma, photodynamic therapy with biliary stent has been known for palliation of jaundice and improving survival. But most of therapeutic effects were expected to delay bile duct obstruction rather than to decrease the tumor. Recently orally available chemotherapeutic agent, S-1 was reported as effective in patients with bile duct adenocarcinoma. The investigators' aims of study evaluate the combined effect of photodynamic therapy and...
The aim of this study is to evaluate adjuvant effect of antimicrobial photodynamic therapy in periodontal treatment and salivary status of type 1 diabetes patients.
The purpose of this study is to review the performance and success rate of an FDA approved cementless hip replacement part called the Trident II Tritanium Acetabular Shell. The study will specifically look at the need to revise the hip replacement after 5 years. This will be compared to how much this happens in patients who have hip replacement with similar cementless acetabular shells.
The primary objective of this study is to obtain implant survivorship and clinical outcomes data for the commercially available G7 BiSpherical Acetabular Shell.
Mutations in the PDE6A gene - encoding the -subunit of the rod cGMP-phosphodiesterase - account for 1% of autosomal recessive retinitis pigmentosa (arRP) through impaired regulation of cGMP levels in the rod outer segment. This study aims for a detailed clinical characterization of patients with PDE6A mutations in preparation of a clinical gene replacement study (phase I/II safety trial).
This is an open-label, randomized, 3 treatment, 3-period, 6-sequence, crossover study conducted at a single study center to characterize the relative bioavailability of relacorilant administered as 3×100-mg softgel capsules (Treatment A), 3×100 mg hard-shell capsules (Treatment B), and 6×50-mg hard shell capsules (Treatment C/reference) in healthy, fasted, adult subjects. Eligible subjects will participate in 3 treatment periods. During each treatment period, subjects...
The nanoparticles (NP) are defined as particles whose size is no greater than 100 nanometers. However, their impact on health remains little evaluated. Placental transfer of NP has been proven in many studies in vitro and in vivo in animals, and toxicity in the fetus has been studied in many animals. The investigators seem interesting at first to establish the mineralogical load in the amniotic fluid in humans. The first objective of this study is to determine the mineralogic...
The purpose of this study is to evaluate a hip implant system used when a previous hip replacement surgery has failed.
This trial is designed to evaluate the efficacy of walnut shell glasses moxibustion for dry eye syndrome compared with sodium hyaluronate eye drops.
This is a phase 1 clinical trial evaluating the safety, tolerability of escalating doses of AGuIX-NP in combination with radiation and cisplatin in patients with locally advanced cervical cancer. Dose escalation will be conducted using the modified toxicity probability interval (mTPI) method. Three dose levels of intravenous AGuIX nanoparticles will be explored: 20mg/kg (level -1), 30 mg/kg (level 1) and 50 mg/kg (level 2).

The aim of this study is to evaluate the antibacterial activity of crosslinked quaternary ammonium polyethylenimine (PEI) nanoparticles incorporated at 1-2% w/w in a commercial soft liner material when compared to the commercial soft liner material. The investigators' results in vitro showed a significant delay in bacterial growth. Therefore, the investigators assume to have the same delay in vivo- on patients.
The effect of Antibacterial Nanoparticles, Incorporated in cement, on S.mutans in the margins of provisional restorations is going to be examined clinically by using two kinds of provisional cement 1. cement with out antibacterial nanoparticles. 2.cement with small addition of IABN. after one week in the mouth the crowns are to be removed and examined for the presence and quantity of s. mutans. in vitro tests of the same has shown significant reduction in bacterial population ...
