Ingia / Ingia

The commission of this article plunged me into doubt. First I should confess that I don't find excuse to escape this part if somebody wants to minimally deepen in the knowledge of the biological effects of this energy source. Secondly, when we talk about results, we use terms made and defined by

Laser induced fluorescence attenuation spectroscopy: detection of hypoxia.

Ingia / Ingia

The development of a new laser-induced fluorescence (LIF) spectroscopy technique for the measurement of the attenuation spectrum of tissue is described. The technique, termed laser-induced fluorescence attenuation spectroscopy (LIFAS), has been applied to study the effects of hypoxia on the in vivo

Crimping of a laser tube resulting in hypoxemia.

Ingia / Ingia

The effects of laser wavelength (355 nm and 532 nm) and laser pulse energy on the quantitative analysis of LiFePO₄ by atom probe tomography are considered. A systematic investigation of ultraviolet (UV, 355 nm) and green (532 nm) laser assisted field evaporation has revealed distinctly different

Refractive changes caused by hypoxia after laser in situ keratomileusis surgery.

Ingia / Ingia

OBJECTIVE To determine whether hypoxia induces refractive changes in subjects who have had laser in situ keratomileusis (LASIK) refractive surgery. METHODS Prospective paired eye clinical trial. METHODS There were 20 LASIK subjects (40 eyes) and 20 myopic non-LASIK controls (40 eyes). METHODS Each

Ingia / Ingia

Argon laser photocoagulation for diabetic retinopathy predominantly involves scatter photocoagulation of either the macula (for diabetic macular edema) or a large portion of the retina (panretinal photocoagulation). In both cases the laser treatment destroys a part of the photoreceptor layer,

Ingia / Ingia

Effects of infrared cold laser radiation (IRCLR) on mutagenesis and proliferation of the corneal epithelium were studied with laboratory white mice subjected to instigated circulatory hypoxia of the brain. The experiment was to reveal whether IRCLR influences the frequency of chromosomal

Ingia / Ingia

OBJECTIVE The purpose of the study was to assess if a scanning laser ophthalmoscope (SLO), Optomap 200Tx, could be used for measurements of hemoglobin oxygen saturation in retinal blood vessels. METHODS Optomap 200Tx uses two lasers for image acquisition, 532 and 633 nm. Retinal images of healthy

Laser smoke effect on the bronchial system.

Ingia / Ingia

The photoresection of endobronchial tumors produces smoke which is partly inhaled by the patient as well as the surgical staff. In an animal study we investigated whether a single exposure or repetitive exposures to smoke might have harmful side effects on the airways. Eleven sheep were exposed to

Experimental studies of stereotactic laser balloon hyperthermic treatment.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

OBJECTIVE The hyperthermic treatment of small malignant brain tumors in basal ganglia and other eloquent cortical areas was investigated with a stereotactic Nd:YAG laser balloon unit. METHODS An Ultra Line fiber (Heraeus Laser Sonics, CA) was inserted into a 6 F silicone balloon catheter, which

[Excimer laser extraction of pacemaker and defibrillator leads].

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

BACKGROUND Pacemaker infection or some lead dysfunctions are an indication for removal of all foreign material. The use of laser energy is a new method for extraction of fixed leads that have been in place for a long time. There are only a few reports on results and complications of laser extraction

Limb blood flow after class 4 laser therapy.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

BACKGROUND Laser therapy is purported to improve blood flow in soft tissues. Modulating circulation would promote healing by controlling postinjury ischemia, hypoxia, edema, and secondary tissue damage. However, no studies have quantified these responses to laser therapy. OBJECTIVE To determine a

[Laser spectroscopy--a new procedure in fetal monitoring].

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Monitors for laser spectroscopy are available as an additional tool for foetal surveillance. Using this technique, continuous and non-invasive registration of four biochemical parameters (HbO2, HbR, blood volume and cytochrome aa3) can be performed. The calculation is based on the optical density
