Abstract:
The carnivorous fungus Drechslerella dactyloides can form constricting rings through hyphal specialization to capture nematodes. The formation of constricting rings is a prerequisite for capturing nematodes and a characteristic of entering the carnivorous stage. Currently, there is limited research on the molecular mechanism of constricting ring formation. In this study, two D. dactyloides mutants unable to form constricting rings were obtained through UV irradiation mutagenesis, and their growth and development phenotypes were compared with the wild-type strain. Transcriptome comparisons reve

Abstract:
A variety of metallic and non-metallic rings causing constriction to the external genitalia have been described in the literature across all ages. The adult population frequently reports erotic or autoerotic goals when intentionally placing constricting devices. In adults these constricting bands are placed deliberately by the person himself to influence blood circulation and thereby obtain prolonged erection and/or sexual pleasure. A compilation of 3 rare case presentations in the casualty of JJM Medical College Davangere were collected and studied. The present case series shows that sexual p

Abstract:
Cytokinesis in animal cells requires the constriction of an actomyosin contractile ring, whose architecture and mechanism remain poorly understood. We use laser microsurgery to explore the biophysical properties of constricting rings in Caenorhabditis elegans embryos. Laser cutting causes rings to snap open. However, instead of disintegrating, ring topology recovers and constriction proceeds. In response to severing, a finite gap forms and is repaired by recruitment of new material in an actin polymerization–dependent manner. An open ring is able to constrict, and rings repair from successive

Abstract:
Vohwinkel syndrome or hereditary mutilating keratodermatitis is a rare condition producing palmo-plantar hyperkeratosis and constricting rings of the fingers and toes which can progress to compromise neurovascular function and mobility. Medical treatment with oral retinol derivatives is recommended when its use is not contra-indicated. This paper describes surgical correction of the constricting rings on both hands in a 33-year-old woman affected by this condition.

Abstract:
The cytokinetic ring generates tensile force that drives cell division, but how tension emerges from the relatively disordered ring organization remains unclear. Long ago, a musclelike sliding filament mechanism was proposed, but evidence for sarcomeric order is lacking. Here we present quantitative evidence that in fission yeast, ring tension originates from barbed-end anchoring of actin filaments to the plasma membrane, providing resistance to myosin forces that enables filaments to develop tension. The role of anchoring was highlighted by experiments on isolated fission yeast rings, where s

Amniotic Band Syndrome (ABS) is a complex condition characterized by constricting rings and tissue synechiae, resulting in tissue necrosis and congenital anomalies. In newborns and infants with ABS, tissue necrosis can be profound, requiring a tissue defect reconstruction, realized by a Keystone Perforator Island Flap (KF). Primarily used for reconstruction after skin cancer excisions, KF’s applications expanded to defects of various etiologies and disorders throughout the body. Subsequently, additional KF types adapted to the particular tissue defects were developed. The KF’s preparation is r

Background: Various techniques have been described for removal of a tight constricting ring from a finger. A novel procedure is described in this article. Methods: The method is a modification of the string wrap or winding technique. A 1-inch Coban wrap, lubricant, and pickups are all that is required. Results: The author has used this method to remove constricting rings from swollen and arthritic fingers in 5 patients. The technique has been successful in all cases, and no complications occurred. Conclusions: The Coban method is a quick, easy, and inexpensive technique for ring removal from a

Abstract:
Penile rings have been used to help sustain erection and enhance sexual pleasure for centuries. Constriction of the penis reduces the outflow of blood from the cavernosal tissue. However, if left for an extended time period, a condition called penile ring entrapment can occur. This may result in severe edema, gangrene, necrosis, and even penile amputation. Penile ring entrapment is a very rare condition; complete urinary obstruction with concomitant bladder rupture as a result renders this case even more extraordinary.

Abstract A 3D parallel high-order spectral difference (SD) solver with curved local mesh refinement is developed in this research to simulate flow through stenoses of varied degrees (50%, 60%, 65%, 70% and 75%) of radius constriction at inlet Reynolds number of 500. This solver employs high-order curved mesh in the vicinity of arterial wall and the local mesh refinement technique reduces the overall computational cost by distributing more elements in critical regions. In simulation of flow through stenosis of 50% radius constriction, velocity profiles predicted from the SD solver agree well wi

Laser surface texturing (LST) provides a unique method for applying custom textures to metals, ceramics, and polymers. Etsion has presented a new type of mechanical seal by applying laser surface texturing onto the faces. According to Etsion, such a textured face seal (LST-MS) helps to reduce face friction and wear and can be used at higher sealed fluid pressures than that of a plain face seal. Such a new seal may be subjected to face deformation, and study on the effect of face deformation on sealing behavior of a LST-MS is important.
