Background
We know that SWL started on February 07, 1980, by Christian Chaussy with a wide range of indications. Complication rate has always remained very low and usually limited to minor side ...effects and complications. This study shows the impact of different shock wave release frequencies 60, 80 & 100/min on disintegration of renal stones.
Methods
A total number of 210 patients with mean age (40 ± 15) years with renal stone who were candidate for SWL divided into 3 groups each are 70 patients on rate 60,80 and 100 per min), Chi-Square test, Fisher’s exact test used in the study.
Results
Complete stone clearance( defined as complete stone free) was obtained in 184 patients 87.6% after one session, the highest success rate 94.3% were obtained in the second group of patients ( with shock wave frequency 80/min) followed by the first group 87.1% (with shock wave frequency 60/min), and patients with highest frequency (100/min) had the lowest success rate 81.4%.
Conclusions
The best option is using intermediate shock wave rate 80/min to obtain highest success rate and mild pain. Using high rate 100/min is not favorable due to least disintegration rate with highest pain. Using rate 60/min shows less success than rate 80/min despite it less painful.

In the present paper, we introduced two approximation methods to investigate the spherically compressed lithium atom under the influence of Debye plasma. Specifically, the diffusion and the ...variational Monte Carlo methods are used for the first time to study this case. We incorporated an exponential screening into the nuclear Coulomb potential to account for the plasma influence. We focused our investigation on analyzing the combined effect of compression and plasma environment on the behavior of the lithium atom in its ground state. The resulting outcomes exhibited consistent pattern across various confinement radii Rc and Debye plasma lengths μ. Many of the results are novel contributions, as they have yet to be explored. Moreover, the findings from this study demonstrated reasonable agreement with the limited existing theoretical results.

White mold, caused by the necrotrophic fungus
, is a challenging disease to common bean cultivation worldwide. In the current study, two non-proteinogenic amino acids (NPAAs),
-aminobutyric acid ...(GABA) and
-alanine, were suggested as innovative environmentally acceptable alternatives for more sustainable management of white mold disease.
, GABA and
-alanine individually demonstrated potent dose-dependent fungistatic activity and effectively impeded the radial growth and development of
mycelium. Moreover, the application of GABA or ß-alanine as a seed treatment followed by three root drench applications efficiently decreased the disease severity, stimulated plant growth, and boosted the content of photosynthetic pigments of treated
-infected plants. Furthermore, although higher levels of hydrogen peroxide (H
O
), superoxide anion (O
), and malondialdehyde (MDA) indicated that
infection had markedly triggered oxidative stress in infected bean plants, the exogenous application of both NPAAs significantly reduced the levels of the three studied oxidative stress indicators. Additionally, the application of GABA and
-alanine increased the levels of both non-enzymatic (total soluble phenolics and flavonoids), as well as enzymatic (catalase CAT, peroxidases POX, and polyphenol oxidase PPO) antioxidants in the leaves of
-infected plants and improved their scavenging activity and antioxidant efficiency. Applications of GABA and
-alanine also raised the proline and total amino acid content of infected bean plants. Lastly, the application of both NPAAs upregulated the three antioxidant-related genes

, and
. Collectively, the fungistatic activity of NPAAs, coupled with their ability to alleviate oxidative stress, enhance antioxidant defenses, and stimulate plant growth, establishes them as promising eco-friendly alternatives for white mold disease management for sustainable bean production.
1,3-Disubstituted-4-thioxoimidazolidin-2-one derivatives with various substituents at N.sup.1 and N.sup.3 were synthesized with high yields and excellent purity by the reaction of various ...N-arylcyanothioformamide derivatives with isocyanate derivatives. The activity of these products as antibacterial and antifungal agents was studied to through some light on structural activity relationship. Some of synthesized compounds showed significant antibacterial and antifungal activities. Most of the imidazole derivatives possess significant antifungal activity aginst S. cerevisiae (MIC 1-10 microg mL.sup.-1). As comparision with ketoconazole, most of the imidazole derivatives showed activity ranging from 50 % less activity to fourfold activity. Keywords: N-arylcyanothioformamides, imidazolidineiminothiones, isocyanates, antimicrobial activity.

The synthesized compounds were tested against bacterial and fungal strains. Most of compounds, such as 2-(4-(3-(3-bromophenyl)thioureido)benzamido)acetic acid and 2-(4-(3-(4-(N-pyrimidin-2-ylsulfamoyl)phenyl)thioureido)benzamido)acetic acid, showed significant antibacterial and antifungal activities. These compounds comprise a new class of promising broad-spectrum antibacterial and antifungal agents.

Abstract Introduction Expression of cancer testis antigens (CTAs) has been associated with prognosis in gastrointestinal stromal tumors (GIST) and other malignancies. CTAs are currently being ...investigated for cancer immunotherapy. Materials and methods We analyzed two CTAs, CT10/MAGE-C2 and GAGE, in 51 GIST by immunohistochemistry and correlated it with established histopathological criteria for malignancy. Results GAGE expression was found in 6/51 (12%) patients, whereas 5/51 (10%) patients expressed CT10/MAGE-C2. 7/51(14%) patients expressed at least one of both CTAs, in 4/51 (8%) patients both CTAs were positive. High-grade GIST are more likely to express GAGE ( p = 0.002) and CT10/MAGE-C2 ( p = 0.007) compared to less aggressive tumors. All patients with GAGE or CT10/MAGE-C2 expression had moderate- or high-risk of recurrence according to the established risk criteria. The presence of GAGE correlates with mitotic rate ( p = 0.001) and tumor size ( p = 0.02), but not with tumor location ( p = 0.60). CT10/MAGE-C2 also significantly correlates with mitotic rate ( p = 0.004) and tumor size ( p = 0.002), whereas no correlation could be found with tumor location ( p = 0.36). Discussion CT10/MAGE-C2 and GAGE should be explored together with other previously described CTAs as targets for immunotherapy of GIST in cases, which are refractory to conventional therapy.
► Electron beam irradiation was used as a new fixation tool of vat dyes. ► The radiation curable formulations free from reducing agent and thickener. ► This process reduces all the processes of ...conventional method in one step. ► The effective conditions were: monomer/oligomer ratio of (25/75wt%) and irradiation dose of 75kGy. ► Vat printing by electron beam affords color yield higher than the conventional method.
Accelerated electrons delivered by electron beam accelerator were used to fix vat colors, incorporated in curable formulations containing diluting monomer and an oligomer, to cellulosic fabric, cotton and polyester fabric. Tetrahydrofurfuryl acrylate, hexane dioldiacrylate, monomers and trifunctional urethane methacrylate, oligomer were used as curable base beside ethylene glycol. The fabrics were printed with these formulations and exposed to various doses of electron beam irradiation generated from the 1.5MeV (25kW) electron beam accelerator machine. Critical factors included the irradiation dose, formulation composition, and vat color concentration were studied. The fabrics printed with the vat colors by electron beam irradiation displayed higher color yield than those fabrics printed by the conventional curing at equal vat color ratios. The durable properties of fabrics printed by electron beam irradiation except the roughness properties are extremely better than those printed by conventional fixation method.
