Background: Pyogenic granuloma is a benign vascular proliferation that is often related to minor trauma by the patient. Objective: Evaluation of the efficacy of cryotherapy in the treatment of pyogenic granuloma. Patients and Methods: Hundred and forty-six patients with pyogenic granuloma were treated by cryosurgery using liquid nitrogen and cotton tip applicator in an open clinical trial. This...

Cryonic suspension is a method of stabilizing the condition of someone who is terminally ill so that they can be transported to the medical care facilities that will be available in the late 21st or 22nd century. There is little dispute that the condition of a person stored at the temperature of liquid nitrogen is stable, but the process of freezing inflicts a level of damage which cannot be re...

Microscopy is very important in scientific research, particularly in the development of new materials for several engineering applications including medicine. The recently developed high-Tc superconducting materials and their performance at higher magnetic fields and higher temperatures are crucial important for real applications. The performance properties are mainly controlled by nanostructur...

Some Europium(III) dibenzoylmethide and benzoylacetonate complexes have been subjected to Mössbauer studies at liquid nitrogen temperature. An attempt is made to discuss covalency in these complexes in terms of 6s, 4f and/or 5d orbital participation in the bond formation. Small linewidths are correlated to less symmetric structures. Resonance effects reflect the polymeric nature of these chelates.

statement of the problem: melanin pigmentation of the gingiva is a crucial esthetic problem. a variety of methods have been used for gingival depigmentation. purpose: the purpose of this study was to compare the results of two treatment modalities: scalpel technique and cryotherapy with liquid nitrogen in treatment of gingival pigmentation. materials and method: twenty patients with chief compl...

The potential of GENIUS as a dark matter detector is discussed. A study was performed to demonstrate the good behaviour of the proposed detector design of naked HPGe-crystals in liquid nitrogen. The expected background components were simulated and are discussed in some detail.With the obtained background GENIUS could cover a large part of the favoured MSSM parameter-space.

An effect of rolling temperature on the mechanical properties and microstructural evolution of an Al-Mg-Si alloy was studied. The material was rolled up to a true strain of ∼0.7 at three different temperatures viz; room temperature, liquid propanol and liquid nitrogen. The liquid nitrogen rolled sample exhibited superior properties with a yield and tensile strength of 332 MPa and 364 MPa, respe...

Background: Cellulytic enzymes including carboxymethyl cellulases play the key role in hydrolysis of cellulose, a huge organic carbon reservoir on earth, into monomeric sugars and their eventual conversion into valuable chemicals and energy sources. Objectives: In this study, we described the identification of a basidiomycete isolate NDVN01 and optimization of culture conditions and medium com...
