background: in vitro maturation (ivm) of immature oocytes collected from ovary has been proposed for fertility preservation. in addition, quality of oocytes post ivm is one of the factors determining its developmental competence. by using the non-invasive polscope system, both meiotic spindle (ms) and zona pellucida (zp) can be assessed in living oocytes. objective: the aim was to investigate t...

Introduction: Ability to reconstruct the papilla in anterior maxilla is important aspect of perio-plastic surgery. In most articles, connective tissue is used with different designs of incisions. The aim of this study was to use sub-epithelial connective tissue graft (SCTG) with two types of incisions called papilla preservation and semilunar. Materials & Methods: This basic randomized clinica...

Background: Epididymal spermatozoa have been used for production of offspring from genetically important animals after they are dead. To attain optimal fertility with epididymal spermatozoa, they should be preserved in a suitable medium in 37°C. Preservation media provides requirement for spermatozoa and affects its motility, viability, and fertility. Sucrose is one of the important components ...

groundwater can be used directly or indirectly and any decline in its quality or quantity maynegatively impact the environment. through groundwater valuation, people are made aware of the fact thatgroundwater is not free of charge and therefore the significance of groundwater preservation is established. in this study, groundwater quality preservation value has been estimated for the city of ya...

Recall that a continuous function $fcolon Xto Y$ between Tychonoff spaces is proper if and only if the Stone extension $f^{beta}colon beta Xtobeta Y$ takes remainder to remainder, in the sense that $f^{beta}[beta X-X]subseteq beta Y-Y$. We introduce the notion of ``taking remainder to remainder" to frames, and, using it, we define a frame homomorphism $hcolon Lto M$ to be $beta$-proper, $lambd...

In spite of the technologies developed during the last decade, the level of food loss is still high and is reported in many countries. According to the United Nations, more than 30 per cent of the mortality rate world-wide is caused by alimentary diseases. The desire of most countries to make food safer for consumption requires better food preservation and production techniques. In this regard,...

We present some model theoretic results for {L}ukasiewiczpredicate logic by using the methods of continuous model theorydeveloped by Chang and Keisler.We prove compactness theorem with respect to the class of allstructures taking values in the {L}ukasiewicz $texttt{BL}$-algebra.We also prove some appropriate preservation theorems concerning universal and inductive theories.Finally, Skolemizatio...

BACKGROUND The intestine is extremely sensitive to ischemic preservation and reoxygenation injury. Current vascular perfusion and cold storage with University of Wisconsin (UW) solution neglect the intestinal lumen and the ongoing mucosal metabolism during hypothermia. This study was designed to test the effects of luminal preservation with an alternative preservation solution in addition to th...
