Induced abortion is an important public health issue in the occupied Palestinian territories (OPT), where it is illegal in most cases. This study was designed to elicit the views of Palestinian women on induced abortion given the unique religious, ethical and social challenges in the OPT. Sixty Palestinian women were interviewed on their perceptions of the religious implications, social consequences and accessibility of induced abortions in the OPT at Al-Makassed Islamic Charitable Hospital in East Jerusalem...

Cancer has long been known to histologically resemble developing embryonic tissue. Since this early observation, a mounting body of evidence suggests that cancer mimics or co-opts developmental processes to facilitate tumor initiation and progression. Programs important in both normal ontogenesis and cancer progression broadly fall into three domains: the lineage commitment of pluripotent stem cells, the appropriation of primordial mechanisms of cell motility and invasion, and the influence of multiple aspects of the microenvironment on the parenchyma...

A stripe pattern is an aposematic or camouflage coloration often observed among various caterpillars. However, how this ecologically important pattern is formed is largely unknown. The silkworm dominant mutant Zebra (Ze) has a black stripe in the anterior margin of each dorsal segment. Here, fine linkage mapping of 3,135 larvae revealed a 63-kbp region responsible for the Ze locus, which contained three candidate genes, including the Toll ligand gene spätzle3 (spz-3). Both electroporation-mediated ectopic expression and RNAi analyses showed that, among candidate genes, only processed spz-3 induced melanin pigmentation and that Toll-8 was the candidate receptor gene of spz-3 This Toll ligand/receptor set is also involved in melanization of other mutant Striped (p(S) ), which has broader stripes...

While sex is an ancient and highly conserved eukaryotic invention, self-incompatibility systems such as mating types or sexes appear to be derived limitations that show considerable evolutionary plasticity. Within a single class of ciliates, Paramecium and Tetrahymena species have long been known to present a wide variety of mating type numbers and modes of inheritance, but only recently have the genes involved been identified. Although similar transmembrane proteins mediate self/nonself recognition in both ciliates, the mechanisms of mating type determination differ widely, ranging from Mendelian systems to developmental nuclear differentiation, either stochastic or maternally inherited...

Motivated by a study measuring diabetes-related risk factors and complications, we postulate an extension to the standard formulation of joint models for longitudinal and survival outcomes, wherein the longitudinal outcome has a cumulative effect on the hazard of the event, weighted by recency. We focus on the relationship between the biomarker HbA1c and the development of sight threatening retinopathy, since the impact of the HbA1c marker on the risk of sight threatening retinopathy is expected to be cumulative, with the evolution of the HbA1c marker over time contributing to progressively greater damage to the vascular structure of the retina...

Eukaryotic pathogens display multiple mechanisms for breaching the blood-brain barrier (BBB) and invading the central nervous system (CNS). Of the fungal spp., that cause disease in mammals, only some cross brain microvascular endothelial cells which constitute the BBB, and invade the brain. Cryptococcus neoformans, the leading cause of fungal meningoencephalitis, crosses the BBB directly by transcytosis or by co-opting monocytes. We previously determined that Mpr1, a secreted fungal metalloprotease, facilitates association of fungal cells to brain microvascular endothelial cells and we confirmed that the sole expression of CnMPR1 endowed S...

Multiple keratocystic odontogenic tumors are one of the key features of Gorlin-Goltz syndrome. A 15-year-old nonsyndromic female child presented with multiple keratocystic odontogenic tumors. The presence of the tumors was observed in immunological examinations. The images led to the suspicion of Gorlin-Goltz syndrome which was discarded after analyzing the patient's medical history and complementary examinations. Le Fort I osteotomy was opted to access the maxillary tumors favoring visibility and allowing simultaneous bilateral accesses...

REVIEW
Jiazhang Qiu, Zhao-Qing Luo
Legionella pneumophila and Coxiella burnetii are two evolutionarily related intracellular pathogens that use the Dot/Icm type IV secretion system to translocate effectors into host cells. These effectors are essential for the establishment of membrane-bound compartments known as replication vacuoles, which enable the survival and replication of bacteria inside host cells. The effectors interfere with diverse signalling pathways to co-opt host processes, such as vesicle trafficking, ubiquitylation, gene expression and lipid metabolism, to promote pathogen survival...

The 'brain regionalization genes' Six3/6, Otx, Pax2/5/8, Gbx, and Hox1 are expressed in a similar fashion in the deuterostome, ecdysozoan, and the cephalopod brain, questioning whether this holds also true for the remaining Mollusca. We investigated developmental Gbx-expression in representatives of both molluscan sister groups, the Aculifera and Conchifera. Gbx is expressed in the posterior central nervous system of an aculiferan polyplacophoran and solenogaster but not in a conchiferan bivalve suggesting that Gbx, together with Six3/6, Otx, Pax2/5/8, and Hox1, is involved in central nervous system regionalization as reported for other bilaterians...

HIV-1 co-opts several host machinery to generate a permissive environment for viral replication and transmission. In this work we reveal how HIV-1 impacts the host translation and intracellular vesicular trafficking machineries for protein synthesis and to impede the physiological late endosome/lysosome (LEL) trafficking in stressful conditions. First, HIV-1 enhances the activity of the master regulator of protein synthesis, the mammalian target of rapamycin (mTOR). Second, the virus commandeers mTOR-associated late endosome/lysosome (LEL) trafficking and counteracts metabolic and environmental stress-induced intracellular repositioning of LEL...

INTRODUCTION: Child maltreatment involves acts of omission (neglect) or commission (abuse) often by caregivers that results in potential or actual harm to a child. The Building Blocks trial (ISRCTN23019866) assessed the short-term impact of an intensive programme of antenatal and postnatal visiting by specially trained nurses to support young pregnant women in England. The Building Blocks: 2-6 Study will assess the medium-term impacts of the programme for mothers and children (n=1562), through the linkage of routinely collected data to the trial data, with a particular emphasis on the programme's impact on preventing child maltreatment...

BACKGROUND: Chemotherapy for breast cancer may have a negative impact on reproductive function due to gonadotoxicity. Fertility preservation via banking of oocytes or embryos after ovarian stimulation with FSH can increase the likelihood of a future live birth. It has been hypothesized that elevated serum estrogen levels during ovarian stimulation may induce breast tumour growth. This has led to the use of alternative stimulation protocols with addition of tamoxifen or letrozole. The effectiveness of these stimulation protocols in terms of oocyte yield is unknown...

This article analyzes the writings of Elisabeth Kübler-Ross through the discursive lens of the phrase "dying with dignity." For her, the phrase meant allowing someone to die comfortably his/her own death. This phrase has to be understood in relationship with the final "stage of acceptance" of her model. Describing this key part of her well-known scientific output, she often used, in the early 1970s, the phrase "dying in peace and dignity." An evaluation of the evidence suggests that because the concept of dignity was co-opted by the pro-euthanasia movement during this decade, the language of dignity was little by little abandoned by her...

Hypertrophic degeneration of the inferior olive is mainly observed in patients developing palatal tremor (PT) or oculopalatal tremor (OPT). This syndrome manifests as a synchronous tremor of the palate (PT) and/or eyes (OPT) that may also involve other muscles from the branchial arches. It is associated with hypertrophic inferior olivary degeneration that is characterized by enlarged and vacuolated neurons, increased number and size of astrocytes, severe fibrillary gliosis, and demyelination. It appears on MRI as an increased T2/FLAIR signal intensity and enlargement of the inferior olive...

INTRODUCTION: Pseudoaneurysms are a pulsatile hematoma caused by hemorrhage on soft tissues. It is an uncommon condition with many different etiologies. We report a case of a giant pseudoaneurysm caused by iatrogenic injury on the brachial artery. PRESENTATION OF CASE: A 42 year-old male was submitted to our Vascular Surgery service with an enlargement of the right upper limb and a history of myocardial infarction. 60days before the patient reached our service, he was submitted to a cardiac catheterization performed by another medical team, since the catheter was placed on the right brachial artery near the cubital fossa, we suspected an iatrogenic pseudoaneurysm, which was confirmed by his clinical history and physical exam...

Interferon effector functions and autophagy are evolutionarily conserved arms of cell-autonomous immunity that restrict replication of intracellular pathogens. In this issue of Cell Host and Microbe, Biering et al., (2017) demonstrate how host cells co-opt sequential action of autophagy proteins and IFN-inducible GTPases to inhibit replication of positive-sense RNA viruses.

Purpose Cigarette smoking in the perinatal period is associated with costly morbidity and mortality for mother and infant, yet many women continue to smoke throughout their pregnancy and following delivery. This report describes tobacco use prevalence among perinatal smokers identified through an "opt-out" inpatient smoking cessation clinical service. Description Adult women admitted to the peripartum, delivery, and postpartum units at a large academic hospital were screened for tobacco use. Smokers were identified through their medical record and referred to a bedside consult and follow-up using an interactive voice response (IVR) system to assess smoking up to 30 days post-discharge...
