objective: this study examines the effects of hydrostatic pressure on in vitro maturation (ivm) of oocytes derived from in vitro grown follicles. materials and methods: in this experimental study, preantral follicles were isolated from 12-day-old female nmri mice. each follicle was cultured individually in alpha minimal essential medium (α-mem) under mineral oil for 12 days. then, follicles wer...

we present a case of infantile intussusception treated successfully using hydrostatic reduction, highlighting the importance of non-surgical techniques as the first line of management for this entity. physicians should strive for mastery over such techniques by extensive training to prevent unwanted surgical procedures in such cases.

immature teeth have a large apical opening and thin divergent or parallel dentinal walls; hence, with conventional needle irrigation there is a very high possibility of extrusion. this study was done to compare the apical extrusion of naocl in an immature root delivered using endovac and needle irrigation.eighty freshly extracted maxillary central incisors were decoronated followed by access ca...

3D printing of bio-based nanomaterials into complex structures with design flexibility, structural anisotropy, and long-term stability is a key issue for biomedical applications. Herein, 3D-printed ionically crosslinked anisotropic, water-proof, tunable mechanical properties are fabricated using polysaccharide ink composed nanocellulose, alginate, CaCO3 nanoparticles. The excellent shear thinni...

OBJECTIVES The objective of this study was to determine the various factors that affect the extrusion rate of ventilation tubes (VTs), including the nature of the middle ear effusion. METHODS A retrospective chart review of 82 pediatric patients (177 ears) who received VT insertion surgery under general anesthesia was carried out to evaluate the relationship between various factors and the VT...

The control of tissue growth, which is a key to maintain the protective barrier function of the epithelium, depends on the balance between cell division and cell extrusion rates [1, 2]. Cells within confluent epithelial layers undergo cell extrusion, which relies on cell-cell interactions [3] and actomyosin contractility [4, 5]. Although it has been reported that cell extrusion is also dependen...

This paper presents a new interpretation of the binary blending operator of implicit modeling. Instead of considering the operator as a composition of potential functions, we propose to consider it as an implicit curve extruded in an implicit extrusion field. An implicit extrusion field is a 2D space for which each coordinate is a potential field. The study of general concepts around implicit e...

In the present study the effect of phase volume fraction on the reinforcement of microstructure and tensile properties of composite extrusion process Al6061/SiC has been studied. For this purpose, the base alloy Al6061 using pure aluminum ingots, silicon, of Al-50% Mg, Al-10% Cr and a thin copper rod was prepared. Next, the composite Al6061/5% SiC, Al6061/10% SiC, Al6061/15% SiC and Al6061/20% ...

Previous research into the friction behaviour of elastomers has typically focused on effects velocity, contact pressure, counter surface and lubrication coefficient friction. O-ring type elastomer seals are common in many different industries. Friction plays a critical role during setting service these components. An experimental testing rig been developed that can measure sliding speed hydrost...
