Phylogenetic analysis of early tetrapod evolution has resulted in a consensus across diverse data sets in which the tetrapod stem group is a relatively homogenous collection of medium- to large-sized animals showing a progressive loss of 'fish' characters as they become increasingly terrestrial, whereas the crown group demonstrates marked morphological diversity and disparity. The oldest fossil attributed to the tetrapod crown group is the highly specialized aïstopod Lethiscus stocki, which shows a small size, extreme axial elongation, loss of limbs, spool-shaped vertebral centra, and a skull with reduced centres of ossification, in common with an otherwise disparate group of small animals known as lepospondyls...

BACKGROUND: Chemical sphincterotomy with pharmacological agents is recommended as first line therapy for chronic anal fissures (CAF). Calcium channel blockers (CCB) are associated with similar efficacy but fewer side effects compared to nitrates. However, the optimal formulation (oral versus topical) is unknown. We aimed to perform a systematic review and meta-analysis to compare the effectiveness of oral and topical CCB in the treatment of CAF. METHODS: PubMed and Embase online databases were searched for relevant articles...

Acute oak decline (AOD) is a relatively newly described disorder affecting native oak species in Britain. Symptomatic trees are characterised by stem bleeds from vertical fissures, necrotic lesions in the live tissue beneath and larval galleries of the two spotted oak buprestid (Agrilus biguttatus). Several abiotic and biotic factors can be responsible for tree death, however the tissue necrosis and stem weeping is thought to be caused by a combination of bacterial species. Following investigations of the current episode of AOD which began in 2008, numerous strains belonging to several different bacteria in the family Enterobacteriaceae have been consistently isolated from symptomatic tissue...

BACKGROUND: Eyelid motion analysis can provide important information about ophthalmic, neurologic, and systemic diseases. Routine assessment of eyelid function is currently based mainly on clinical examination estimating Levator Function and static palpebral fissure measurements. Most clinical tools developed to date are cumbersome expensive and difficult to operate. Currently there is no widely available, affordable device providing user friendly precision based evaluation of eyelid kinematics...

The special sensory, motor, and cognitive capabilities of mammals mainly depend upon the neocortex, which is the six-layered cover of the mammalian forebrain. The origin of the neocortex is still controversial and the current view is that larger brains with neocortex first evolved in late Triassic Mammaliaformes. Here, we report the earliest evidence of a structure analogous to the mammalian neocortex in a forerunner of mammals, the fossorial anomodont Kawingasaurus fossilis from the late Permian of Tanzania...

The aim of this ex vivo study was to evaluate the infiltration capability and rate of microleakage of a low-viscous resin infiltrant combined with a flowable composite resin (RI/CR) when used with deproteinised and etched occlusal subsurface lesions (International Caries Detection and Assessment System code 2). This combined treatment procedure was compared with the exclusive use of flowable composite resin (CR) for fissure sealing. Twenty premolars and 20 molars revealing non-cavitated occlusal carious lesions were randomly divided into two groups and were meticulously cleaned and deproteinised using NaOCl (2%)...

INTRODUCTION: Fronto-metaphyseal dysplasia (FMD), also called Gorlin-Cohen syndrome, is a rare syndrome initially described in 1969 by Gorlin and Cohen. Patients present skeletal dysplasia, craniofacial malformations and digit abnormalities. Craniofacial phenotype of FMD is characterized by supraorbital hyperostosis, hypertelorism, down-slanting palpebral fissures, broad nasal bridge and micrognathia. Here we report the first adult case of craniofacial reconstruction with frontal cranioplasty in a patient with FMD...

As surgical proficiency and the development of medical techniques have improved, uniportal video-assisted thoracoscopic surgery (VATS) has emerged as a minimally invasive alternative in the surgical management of lung cancer. The spectrum of uniportal VATS indications is now almost equal to that of conventional VATS. Recent decades have witnessed the emergence of numerous uniportal VATS techniques. A significant proportion of these have to be converted into a multiport approach and even open thoracotomy due to the difficulty of managing the upper lobe vein and bronchus, particularly for the technically challenging left upper lobectomy...

The pilocarpine-induced status epilepticus (SE) rodent model has been commonly used to analyze the mechanisms of human temporal lobe epilepsy. Recent studies using this model have demonstrated that epileptic seizures lead to increased adult neurogenesis of the dentate granule cells, and cause abnormal cellular organization in dentate neuronal circuits. In this study, we examined these structural changes in rats with seizures of varying severity. In rats with frequent severe seizures, we found a clear loss of Prox1 and NeuN expression in the dentate granule cell layer (GCL), which was confined mainly to the suprapyramidal blade of the GCL at the septal and middle regions of the septo-temporal axis of the hippocampus...

Robust and highly active photocatalysts, CdS@MoS2, for hydrogen evolution were successfully fabricated by one-step growth of oxygen-incorporated defect-rich MoS2 ultrathin nanosheets on the surfaces of CdS with irregular fissures. Under optimized experimental conditions, the CdS@MoS2 displayed quantum yield of ~24.2 % at 420 nm and the maximum H2 generation rate of ~17203.7 umol/g/h using Na2S-Na2SO3 as sacrificial agents (λ≥420 nm), which is ~47.3 and 14.7 times higher than CdS (~363.8 μmol/g/h) and 3 wt% Pt/CdS (~1173...

A 24-year-old man presented with orofacial swelling, peripheral facial palsy and fissured tongue. Apart from a previous episode of peripheral palsy, he had no history of illness. Biopsy of the lip, blood tests, magnetic resonance imaging of the head and lumbar puncture showed no pathology. He received systemic prednisone for ten days, and follow-up showed sparse improvement in facial movements. The patient could have been misdiagnosed with Bell's palsy, but the symptoms rather indicated a case of Melkersson-Rosenthal syndrome...
