Misdiagnosis of respiratory epithelial adenomatoid hamartomas for malignant tumors can lead to an aggressive surgical procedure, which is not necessary in the case of a respiratory epithelial adenomatoid hamartoma. Detailed analysis of sinonasal CT scans without contrast can help to distinguish respiratory epithelial adenomatoid hamartomas of the olfactory cleft from small malignant tumors (T1 and T2) of the olfactory clefts. Criteria in favor of diagnosis of small malignant tumors of the olfactory clefts on CT scans without contrast were unilaterality of masses in the olfactory clefts, large olfactory clefts /small olfactory clefts ratio ≥ 2 (sensibility at 91% and specificity at 100%), and presence of bone erosion...

BACKGROUND: Mutations in IRF6, CHUK (IKKA) and RIPK4 can lead to a disease spectrum that includes cutaneous, limb and craniofacial malformations. Loss of these alleles in the mouse leads to perinatal lethality and severe cutaneous, limb and craniofacial defects. Genetic rescue in the mouse has been shown for Ikka and Ripk4. RESULTS: Here, we show partial genetic rescue of Irf6 knockout embryos using the KRT14 promoter to drive Irf6 expression in the basal epithelium...

INTRODUCTION: Preterm infants are commonly treated by non-invasive ventilation (NIV) and nasal continuous positive airway pressure (CPAP), which are associated with fewer complications than nasotracheal intubation. In preterm infants with a cleft lip and palate, this method of respiratory management is difficult or impossible to perform because of air leakage through the cleft defect. CASE: We report a male infant who was born at 29 weeks of gestation with a left complete unilateral cleft lip and palate...

Neuroligins and neurexins promote synapse development and validation by forming trans-synaptic bridges spanning the synaptic cleft. Select pairs promote excitatory and inhibitory synapses, with neuroligin 2 (NLGN2) limited to inhibitory synapses and neuroligin 1 (NLGN1) dominating at excitatory synapses. The cell-surface molecules, MAM domain-containing glycosylphosphatidylinositol anchor 1 (MDGA1) and 2 (MDGA2), regulate trans-synaptic adhesion between neurexins and neuroligins, impacting NLGN2 and NLGN1, respectively...

BACKGROUND: Orofacial clefts (OFCs) are common human birth defects in China. However, studies on the prevalence of OFCs present inconsistent results. The overall prevalence and geographic distribution of OFCs are poorly described in China. Thus, we conducted a systematic review and meta-analysis to estimate the prevalence of OFCs. METHODS: The systematic review and meta-analysis were conducted on the basis of an established protocol (PROSPERO 2015: CRD42015030198)...

Left atrioventricular (AV) valve regurgitation is the most common complication after a atrioventricular canal defect (AVCD) repair. Despite what appears to be a less complex repair, patients with partial and transitional AV canal have higher reoperation rates for left AV valve regurgitation and left ventricular outflow tract (LVOT) obstruction. Retraction of bridging leaflets with secondary attachments to the septal crest commonly produces increased tension and flattening of the medial left AV valve leaflet and LVOT obstruction after cleft closure...

PURPOSE: To assess the surgical and functional outcome of internal direct cyclopexy as therapy of complicated traumatic cyclodialysis. METHODS: The single-centre interventional case-series study included eyes with traumatic cyclodialysis who had consecutively been treated. Internal cyclopexy was performed using double-armed sutures introduced into the eye through the pars plana opposite to the cyclodialysis cleft and which were laid parallel to limbus. Additional procedures included cataract surgery, and pars plana vitrectomy...

Cystic hygroma (CH) is a benign infiltrative malformation of the lymphatic channels. We report a case of a 28-year-old Indian female who presented with rapidly enlarging right sided neck swelling over the posterior triangle since 5 days. Complete resection of CH is sometimes not amenable because of its infiltrative nature and involvement of surrounding vital structures. However, in our patient successful complete surgical resection was undertaken. The MRI findings of our patient were consistent with brachial cleft cyst; this posed a challenge in the diagnosis of CH...

The amino-terminal domain (ATD) of AMPA receptors (AMPARs) accounts for approximately 50% of the protein, yet its functional role, if any, remains a mystery. We have discovered that the translocation of surface GluA1, but not GluA2, AMPAR subunits to the synapse requires the ATD. GluA1A2 heteromers in which the ATD of GluA1 is absent fail to translocate, establishing a critical role of the ATD of GluA1. Inserting GFP into the ATD interferes with the constitutive synaptic trafficking of GluA1, but not GluA2, mimicking the deletion of the ATD...

Approximately 10% of pregnant women are prescribed antidepressant drugs (ADDs), with selective serotonin reuptake inhibitors (SSRIs) the most widely prescribed. SSRIs bind to the serotonin transporter (SERT), blocking the reabsorption of serotonin by the presynaptic neuron and increasing serotonin levels in the synaptic cleft. The serotonergic system regulates a range of brain development processes including neuronal proliferation, migration, differentiation and synaptogenesis. Given the presence of SERT in early brain development, coupled with the ability of SSRIs to cross the placenta and also enter breast milk, concerns have been raised regarding the effects of SSRI exposure on the developing foetus and newborns...

While several studies have investigated maternal exposures as risk factors for oral clefts, few have examined paternal factors. We conducted an international multi-centered case-control study to better understand paternal risk exposures for oral clefts (cases = 392 and controls = 234). Participants were recruited from local hospitals and oral cleft repair surgical missions in Vietnam, the Philippines, Honduras, and Morocco. Questionnaires were administered to fathers and mothers separately to elicit risk factor and family history data...

Heterodimeric HIV-1 RT is composed of p66 and p51 subunits. While in the p51 subunit, the connection domain is tucked in the polymerase cleft,; it is effectively displaced from the cleft of the catalytically active p66 subunit. How is the connection domain relocated from the polymerase cleft of p66? Does RNase H domain have any role in this process? To answer this question, we extended the C-terminal region of p51 by stepwise addition of N-terminal motifs of RNase H domain to generate p54, p57, p60, and p63 derivatives...
