BACKGROUND Recurrent spontaneous miscarriage (RSM) has a multifactorial etiology, mainly due to karyotype abnormalities including balanced translocation, anatomical uterine disorders, and immunological factors, although in 50%-60% the etiology is unexplained. The treatment of RSM remains challenging, and the role of intravenous immunoglobulin (IVIG) in RSM is controversial. CASE REPORT Mrs HM...

Gladiolus is very popular and highly demanded cut flower worldwide however imbalance nutrition reduces its production, additionally irrational combination of nutrient further kindled the situation. The current study was conducted to ascertain the effects of different combinations of N, P and K on growth, floral development, and N, P and K uptake by gladiolus leaves. N, P and K was applied as; w...

BACKGROUND/AIMS The importance of sperm capacitation for mammalian fertilization has been confirmed in the present study via sperm metabolism. Involvement of the metabolic enzymes pyruvate dehydrogenase complex (PDHc) and its E3 subunit, dihydrolipoamide dehydrogenase (DLD) in hamster in vitro fertilization (IVF) via in vitro sperm capacitation is being proposed through regulation of sperm intr...

It is well known that balanced and optimal mineral fertilization (i.e., nitrogen, phosphorus, potassium) can increase yield improve wheat quality. However, there little scientific knowledge on the specific effect of potassium (K) morphological qualitative characteristics rainfed durum under Mediterranean conditions, especially in context Algerian agriculture. Therefore, main objective this stud...

abstract background: the intracytoplasmic sperm injection procedure ending with total fertilization failure is very distressfull event for both the clinician and the patient. objective: the aim of this study was to identify independent factors which could be used to identify total fertilization failure before the day of intracytoplasmic sperm injection. materials and methods: this was a retrosp...

Determining fertilization success of free spawning organisms in the field requires knowledge of how eggs and sperm interact under varying encounter frequencies and durations. In the laboratory, we investigated the relative influence of sperm concentration, egg concentration, sperm-egg contact time, and sperm age on fertilization in the sea urchin Strongylocentrotus franciscanus. Our results ind...

Flowering plants (angiosperms) are the most prevalent and evolutionarily advanced group of plants. Success of these plants is owed to several unique evolutionary adaptations that aid in reproduction: the flower, the closed carpel, double fertilization, and the ultimate products of fertilization, seeds enclosed in the fruit. Angiosperms exhibit a vast array of reproductive strategies, including ...

In grassland ecosystems, N and P fertilization often increase plant productivity, but there is no concensus if fertilization affects soil C fractions. We tested effects of N, P and N+P fertilization at 5, 10, 15 g m-2 yr-1 (N5, N10, N15, P5, P10, P15, N5P5, N10P10, and N15P15) compared to unfertilized control on soil C, soil microbial biomass and functional diversity at the 0-20 cm and 20-40 cm...

production of high quality with high shelf life of apple fruits, is of great importance. present study investigates the effects of ammonium nitrate and iron on quality and antioxidant properties of apple fruit cultivar gala in a randomized complete block design. foliar application of iron chelate in three levels (0, 5 and 10 mg/l) and soil nutrition of ammonium nitrate in three levels as strip ...
