IntroductionThe knowledge of the branching pattern of external branch of the superior laryngeal nerve and its relationship with the superior thyroid artery is the key point for identifying the external branch of the superior laryngeal nerve during surgeries of the neck.Case presentationDuring routine dissection of ...

The Drosophila brain is tracheated by the cerebral trachea, a branch of the first segmental trachea of the embryo. During larval stages the cerebral trachea splits into several main (primary) branches that grow around the neuropile, forming a perineuropilar tracheal plexus (PNP) at the neuropile surface. Five primary tracheal branches ...

The anatomy of the gonadal vein has been the subject of several studies relating particularly to the aetiology and therapy of varicocele and left ovarian vein syndrome. Venography shows the presence of valves, the collateral branches, the anastomoses between the left gonadal vein and the retroperitoneal venous networks and the effective pathways of venous reflux. The authors ...

SummaryDendrite branching and spine formation determines the function of morphologically distinct and specialized neuronal subclasses. However, little is known about the programs instructing specific branching patterns in vertebrate neurons and whether such programs influence dendritic spines and synapses. Using knockout and knockdown ...

The electrocardiographic presence of deep T-wave inversions in a patient presenting with chest pain is highly concerning for cardiac ischemia. There are certain situations, however, when this finding may represent a benign phenomenon. In this report, we illustrate a case of non- ischemia-related T-wave inversion after resolution of a rate-related left bundle-branch block ...

In order to study transitions from normal patterns of electrical activity to abnormal patterns, such

Iatrogenic right ventricular pre-excitation failed to abolish right bundle-branch block in two patients. When `exclusive' His bundle pacing was performed, the QRS complexes, St-V, and St-LVE intervals were similar to the ventricular deflections, H-V, and V-LVE (intervals) recorded during sinus rhythm. `Exclusive' pacing of the ordinary muscle at the right ventricular inflow ...

Seventy three infants who underwent neonatal anatomical correction for transposition of the great arteries with or without a ventricular septal defect were reviewed for evidence of conduction and rhythm abnormalities on preoperative and postoperative 12 lead electrocardiograms and during 24 hour Holter monitoring. There was a partial right bundle branch ...

Identification and complementation of abnormal hyphal branch mutants ahbA1 and ahbB1 in Aspergillus, reproduction, and pathoge- nicity. To investigate branching we screened an Aspergillus nidulans temperature; Heme-binding domain 1. Introduction Like other filamentous fungi Aspergillus nidulans grows by highly

On the basis of our collective experience we have reviewed the disposition of the cardiac conduction tissues as they might be observed by the surgeon in both normal and abnormal hearts. The sinus node lies subepicardially in the terminal sulcus; because of its variable blood supply the entire superior cavoatrial junction is a potential danger area. There are no morphologically ...

SummaryChronic complex regional pain syndrome (CRPS) is a debilitating pain condition accompanied by autonomic abnormalities. We investigated gray matter morphometry and white matter anisotropy in CRPS patients and matched controls. Patients exhibited 1) a disrupted relationship between white matter anisotropy and whole-brain gray matter volume, 2) gray matter atrophy in a ...

Olivocochlear (OC) neurons were studied in a transgenic mouse with deletion of the ?9 nicotinic acetylcholine receptor subunit. In this ?9 knockout mouse, the peripheral effects of OC stimulation are lacking and the peripheral terminals of OC neurons under outer hair cells have abnormal morphology. To account for this mouse�s apparently normal hearing, it has been proposed ...

BackgroundThe pair-rule gene, hairy, encodes a basic helix-loop-helix transcription factor and is required for patterning of the early Drosophila embryo and for morphogenesis of the embryonic salivary gland. Although hairy was shown to be expressed in the tracheal primordia and in surrounding mesoderm, whether hairy plays a role in tracheal development is not known.Principal ...

MicroRNAs (miRNAs) are ?21-nucleotide noncoding RNAs that play critical roles in regulating plant growth and development through directing the degradation of target mRNAs. Axillary meristem activity, and hence shoot branching, is influenced by a complicated network that involves phytohormones such as auxin, cytokinin, and strigolactone. GAI, RGA, and SCR (GRAS) family members ...

Effects of crystal optical branches on Mossbauer effects are analyzed, and a partial explanation for the abnormal temperature dependence of the Mossbauer effect in SnOi and Dy/sub 2/O/sub 3/ is derived. (R.V.J.)

The diagnostic evaluation of patients with isolated left bundle branch block (LBBB) is challenging due to limitations of several non-invasive tests. Our aim was to evaluate the diagnostic value of cardiovascular magnetic resonance (CMR) in asymptomatic patients with LBBB. Sixty-one asymptomatic patients with complete LBBB who were referred for CMR from January 2005 to November ...

This study is the first report of the branching pattern of the four major branches of the subclavian artery in German Shepherd dogs. A total 116 subclavian artery casts made of silicon under mean arterial pressure were analysed. The casts were classified according to their branching order and the ...

This report describes a male infant who developed right upper limb palsy 5 days after birth and contralateral paralysis at 14 days. Abnormal in utero posture of the right arm had resulted in a difficult cephalic delivery. Right shoulder osteomyelitis was diagnosed at age 16 days from clinical, hematologic, and radiologic findings. Antibiotics were administered, followed by ...

The persistent median artery (PMA) may compress the median nerve (MN) and may be a significant supply of blood to the hand. Two cases of unilateral PMA (4%) were detected during the dissection of 50 upper limbs. The first case was a 75-year-old, right-handed male who suffered from chronic pain in both upper limbs, especially the left side. A dissection of his left upper limb revealed a PMA ...

The mammary gland and other treelike organs develop their characteristic fractal geometries through branching morphogenesis, a process in which the epithelium bifurcates and invades into the surrounding stroma. Controlling the pattern of branching is critical for engineering these organs. In vivo, the branching ...

In five cases of anteroseptal myocardial infarction complicated by intermittent right bundle-branch block, the onset of right bundle-branch block provoked the appearance of abnormal Q waves in leads V1 and V2, whereas a small initial R wave was present in the same leads during normal conduction. The intermittency of the conduction ...

Anomalous branching pattern of the left external carotid artery (ECA) was detected in an old man. The ECA branched into high submental artery and large transverse facial artery ending as angular artery compensating for concurrent agenesis of ipsilateral facial artery.

Dowling-Degos disease is a rarely encountered pigmentary disorder in which small brown-to-black macules appear in a clustered or reticulated pattern primarily at flexural sites. It usually occurs as an autosomal dominant trait but sporadic cases have also been reported. Dowling-Degos disease is sometimes associated with other cutaneous abnormalities, many ...

Some forms of epilepsy may arise as a result of pathologic interactions among neurons. Many forms of collective activity have been identified, including waves, spirals, oscillations, synchrony, and neuronal avalanches. All these emergent activity patterns have been hypothesized to show pathologic signatures associated with epilepsy. Here, the authors used 60-channel ...

Septins are cytoskeletal proteins found in fungi, animals, and microsporidia, where they form multiseptin complexes that act as scaffolds recruiting and organizing other proteins to ensure normal cell division and development. Here we characterize the septins AspA and AspC in the multicellular, filamentous fungus Aspergillus nidulans. Mutants with deletions of aspA, aspC, or both aspA and aspC ...
