Failure of neural tube closure in the early embryo causes neural tube defects including spina bifida. Spina bifida lesions predominate in the distal spine, particularly after exposure to the anticonvulsant valproic acid (VPA). How VPA specifically disturbs late stages of neural tube closure is unclear, as neurulation is usually viewed as a uniform 'zippering' process along the spine. We recentl...

INTRODUCTION A safe closure technique of transluminal access is essential for the widespread application of natural orifice transluminal endoscopic surgery (NOTES). AIM To evaluate the feasibility and effectiveness of a novel single loop-and-clips closure technique (KING closure). MATERIAL AND METHODS An experimental survival study using female laboratory pigs was performed. A gastrotomy wa...

In this paper a new type of fuzzy regularity, viz. fuzzy p∗regularity has been introduced and studied by a newly defined closure operator, viz., fuzzy p∗-closure operator. Also we have found the mutual relationship of this closure operator among other closure operators defined earlier. In p∗-regular space, p∗-closure operator is an idempotent operator. In the last section, p∗-closure operator h...

The paper describes a preferential approach for dealing with exceptions in KLM logics, based on the rational closure. It is well known that closure does not allow an independent handling of inheritance different defeasible properties concepts. In this work, we consider alternative construction, called Multi Preference (MP-closure), which has been first considered reasoning DLs. We reconstruct n...

PURPOSE To compare between hand closure and Carter-Thomason technique with respect to following parame­ters, time taken for port site closure, wound infection, wound dehiscence, seroma formation, port site herniation, and ascitic fluid leak. MATERIALS AND METHODS In this study, 200 cases who underwent laparoscopic donor nephrectomy were selected and divided into two groups based on closure te...

This paper considers the relationship between force and form closure. Based on a recently developed mobility theory, we give precise deenitions for 1 st and 2 nd order form closure for frictionless grasps. We also introduce the new concept of 2 nd order force closure. We show for the case of frictionless contacts, a grasp is 1 st order force closure if and only if it is 1 st order form closure....

A famous theorem of Kuratowski states that in a topological space, at most 14 distinct sets can be produced by repeatedly applying the operations of closure and complement to a given set. We re-examine this theorem in the setting of formal languages, where closure is either Kleene closure or positive closure. We classify languages according to the structure of the algebra they generate under it...

Secondary angle closure glaucomas are a distinct entity from primary angle closure glaucoma (PACG). Unlike PACG, secon­ dary angle closure glaucoma’s have an identifiable contributory factor/s for angle closure and obstruction of aqueous flow which is usually unrelieved by iridotomy. The treatment of each type of secondary angle closure glaucoma is varied, so identification of the primary cause...
