Capacitation is a key process through which spermatozoa acquire their fertilizing ability. This event is required for the successful application of assisted reproductive technologies such as IVF. The aim of the present study was to investigate the effect of using a synthetic oviductal fluid medium supplemented with either heparin-hypotaurine alone, in combination with progesterone (P4), 17β-est...

Most calculations of the vibrational scattering of diatom-atom collisions use the breathing sphere approximation (BSA) of orientation averaging the intermolecular potential. The resulting angularly symmetric potential can not cause rotational scattering. We determine the error introduced by the BSA into observables of the vibrational scattering of low-energy homonuclear diatom-atom collisions b...

This study was to investigate the effects of Narrowband Ultraviolet B (NB-UVB) treatment on anxiety and depression in psoriasis. Psoriasis patients are more likely have mental disorders. Previous studies assessed systemic treatments with psoriasis, but NB-UVB remains unknown. prospective enrolled 223 psoriasis patients, all them received therapy for 4 weeks 181 12 weeks. The Area Severity Index...

thin films of binary bi 0 -teo and bi 0 -v 0 systems were prepared by the thermal co-evaporation technique in a vacuum at room temperature. the optical absorption edge of these systems are studied in the wavelength of 200-800 nm using a perkin-elmer uv/vis spectrophotometer. it is found that the value of n=3/2 in the davis-mott equation is best fitted for the fundamental absorption edge for the...

Here we describe the preparation of BSA-FITC-loaded microcapsules as a model protein system for in vivo delivery. BSA-FITC-loaded microcapsules were prepared using a mono-axial nozzle ultrasonic atomizer, varying a number of parameters to determine optimal conditions. The preparation method chosen resulted in a BSA-FITC encapsulation efficiency of approximately 60% and a particle size of approx...

Using UV-Vis spectrophotometric method the interaction of water soluble phthalocyanine, Cobalt(ΙΙ) 4,4′,4′′,4′′′- tetrasulfophthalocyanine(CoTSPc), with bovine serum albumin (BSA) to determine the formation constant and related thermodynamic functions. The measurements were considered in 1mM sodium phosphate buffer, pH 7.0 and at 5 different temperatures 20, 25, 30, 35 and 40ºC. The results sho...

Introduction: Musculoskeletal growth is variable during adolescent period and reaches its maximum by 18 years, whereas hemopoietic parameters reach adult values by 15 years. After adolescence period, the blood parameters may vary with nutrition and built of the individual. The purpose of this study was to find out any correlation between anthropometric and hematological parameters after the ado...

BACKGROUND Gold nanoclusters (AuNCs) are typically composed of several to tens of gold atoms which are stabilized with biomacromolecules such as bovine serum albumin (BSA). Au NCs fluoresces in the visible to near infrared region, in a size-dependent manner. AuNCs solutions have potential as fluorophore in a wide range of biomedical applications such as biodetection, biosensing and bioimaging i...

The effect of culture system and protein supplementation on the development of one-cell porcine embryos was investigated. One hundred and sixty-four one-cell embryos were collected at slaughter from 19 handmated gifts. Culture systems evaluated were microdrops of Whitten's medium (WM) under paraffin oil (M) or tubes with 4.0 ml of WM (T). Also tested was T with a 2.0 ml paraffin oil overlay (O)...
