BACKGROUND Task group number 40 (TG-40) of the American Association of Physicists in Medicine (AAPM) has recommended calibration of any brachytherapy source before its clinical use. GZP6 afterloading brachytherapy unit is a (60)Co high dose rate (HDR) system recently being used in some of the Iranian radiotherapy centers. AIM In this study air kerma strength (AKS) of (60)Co source number thre...

OBJECTIVE To determine the effect of facial skin resurfacing for treatment of actinic keratoses (AKs) and prophylaxis against new primary basal and squamous cell carcinomas in individuals with previous nonmelanoma skin cancer (NMSC) or severe photodamage. DESIGN Randomized, prospective 5-year trial. SETTING Dermatology and otolaryngology clinics of a Veterans Affairs hospital. PATIENTS Th...

BACKGROUND Unicondylar knee arthroplasty (UKA) is a well-established treatment for isolated osteoarthritis (OA) of the medial knee compartment. Aim of this retrospective study was to evaluate the early clinical and radiological outcomes of a consecutive series of patients treated with medial metal backed fixed-bearing UKA. Furthermore, the influence of the component orientation on the outcome w...

Arginine kinase (AK) was isolated from the longitudinal muscle of the sea cucumber Stichopus japonicus. Unlike the monomeric 40 kDa AKs from molluscs and arthropods, but like the cytoplasmic isoenzymes of vertebrate creatine kinase (CK), the Stichopus enzyme was dimeric. To explore the evolutionary origin of the dimeric AK, we determined its cDNA-derived amino acid sequence of 370 residues. A c...

Input: An integer n > 1. 0: if n is a power then output composite fi; 1: r := 2; 2: while (r < n) do 3: if gcd(r, n) 6= 1 then output composite fi; 4: if r is prime then 5: q := largest prime factor of r − 1; 6: if (q ≥ 4√r log n) and (n(r−1)/q 6≡ 1 mod r) then break fi; 7: fi; 8: r := r + 1; 9: od; 10: for a = 1 to 2 √ r log n do 11: if (x− a)n 6≡ (xn − a) mod (xr − 1, n) then output composite...

BACKGROUND Actinic keratosis (AK) is one of the most common skin diseases seen in clinical practice. In the last 5 years, several studies assessing the efficacy of photodynamic therapy in the treatment of multiple AKs have been published. OBJECTIVE We aimed to assess the clinical outcomes of photodynamic therapy in patients with multiple AKs and the correlation of those outcomes with fluoresc...

Nonmelanoma skin cancer, induding both squamous cell carcinoma and basal cell carcinoma, is a significant and increasing health problem in the United States. The precursor lesion of cutaneous squamous cell carcinoma, actinic keratosis (AK), is a m*jor risk factor for nonmelanoma skin cancer, and it is also a marker of longterm sun exposure. AKs themselves can serve as biomarkers in chemoprevent...

Nonmelanoma skin cancer, including both squamous cell carcinoma and basal cell carcinoma, is a significant and increasing health problem in the United States. The precursor lesion of cutaneous squamous cell carcinoma, actinic keratosis (AK), is a major risk factor for nonmelanoma skin cancer, and it is also a marker of long-term sun exposure. AKs themselves can serve as biomarkers in chemopreve...

Az átlátható veremautomata (visibly pushdown automaton) fogalmát R. Alur és P. Madhusudan vezette be 2004-ben [1]. Az „átláthatóság” azt jelenti, hogy az input betűi meghatározzák, hogy olvasásukkal egyidőben milyen veremműveletet hajt végre az automata. Egy bizonyos halmazba tartozó betűk olvasásakor az automata egy szimbólumot helyez a verembe, más betűk olvasásakor kivesz egyet, a többi betű...

We show that AKS-algorithm for primality testing ( see [1]) can be modified to run in Õ(log n) time. We present some remarks and ask two questions related to this algorithm.
