BACKGROUND To date, the role of male factor contributing in evaluation of spontaneous recurrent pregnancy loss (RPL) has been less investigated and there is discrepancy in the role of Y chromosome microdeltions in RPL. Therefore, the current study was designed to examine whether Y chromosome microdeletions were associated with RPL in an Iranian population. METHODS One hundred men from couples...

Recurrent pregnancy loss (RPL) in polycystic ovary syndrome (PCOS), which occurs in ∼50% of total pregnancies is a frequent obstetric complication. Among the several hypotheses, insulin resistance (IR), obesity and hyperhomocysteinemia (HHcy) play significant role/s in RPL. This study was conducted to assess the link between elevated levels of homocysteine and IR in PCOS-associated women with R...

The Internet of Things (IoT) has emerged as a paradigm over the last few years as a result of the tight integration of the computing and the physical world. The requirement of remote sensing makes low-power wireless sensor networks one of the key enabling technologies of IoT. These networks encompass several challenges, especially in communication and networking, due to their inherent constrain...

BACKGROUND Recurrent fetal loss (RPL) is one of the most common cause of sterility. Several studies identified thrombophilia as the principal cause of recurrent pregnancy loss. However, reported studies often do not evaluate other causes of miscarriages in their inclusion and exclusion criteria. So the aim of our study was to investigate the role of inherited thrombophilia in patients with RPL ...

Background: Recurrent pregnancy loss (RPL) is a common problem among couples, and acquired thrombophilia is the well-known etiology of RPL. The aim of this study was to establish the association between inherited thrombophilic gene polymorphisms and RPL. Methods: This case-control study was conducted on 50 women with unexplained RPL and 50 parous women with no history of miscarriage (age range...

An agent that learns about the world while performing its jobs has to plan in a flexible and focused manner: it has to reflect on how to perform its jobs while accomplishing them, focus on critical aspects of important subtasks, and ignore irrelevant aspects of their context. It also has to postpone planning when lacking information, reconsider its course of action when noticing opportunities, ...

Low Power and Lossy Networks (LLNs) are inherently dynamic nodes move or experience link perturbations. Routing packets in LLNs is generally performed by the IETF IPv6 Routing Protocol for Low-Power and Lossy Networks (RPL). To face the dynamics of LLN, RPL is helped by external mechanisms such as Neighbor Unreachability Detection (NUD) or Bidirectional Forwarding Detection (BFD). In this artic...

The CYP17 gene encodes the enzyme cytochrome P450c17alpha, which mediates both 17alpha-hydroxylase and 17,20-lyase activity in the steroid biosynthesis pathway. A T-->C polymorphism in the 5' promoter region of CYP17 has been described. To examine the association between recurrent pregnancy loss (RPL) and a polymorphism in CYP17, a case-control study of 117 cases with RPL and 164 controls was c...

Establishing trust relationships between nodes participating in constructing the routing paths represents a primary security milestone to have reliable routing processes that exclude infected or selfish nodes. In this paper, we propose a new scheme for RPL (Routing Protocol for Low-power and Lossy Networks) named: Metric-based RPL Trustworthiness Scheme (MRTS) to enhance RPL security and deal w...

OBJECTIVE To investigate, in men presenting with recurrent pregnancy loss (RPL), the prevalence of sperm autosome and sex chromosome aneuploidy. DESIGN Retrospective study. SETTING Male infertility clinic. PATIENT(S) A total of 140 men with RPL provided semen samples, and five normozoospermic controls provided 140 semen samples for comparison. Recurrent pregnancy loss, documented in the f...
