Obtaining a reliable distal margin during anterior colorectal resection can be difficult. In this study, endoscopic transmural tattoos were placed to mark the distal transection point in patients with distal colorectal neoplasms who undergo bowel resection. In the operating room, before surgery, sigmoidoscopy is performed with a 2-channel scope using CO₂ insufflation. Through channel 1, a biops...

Seismic reflection and refraction data acquired on four transects spanning the Southeast Greenland rifted margin and Greenland^Iceland Ridge (GIR) provide new constraints on mantle thermal structure and melting processes during continental breakup in the North Atlantic. Maximum igneous crustal thickness varies along the margin from s 30 km in the near-hotspot zone (6 500 km from the hotspot tra...

The genus Chremistica Stål, 1870 is reported from the northeastern region of India for the first time. A new species, Chremistica ribhoi, is described from this region and male genitalia illustrations and scanning electron microscope photographs of the pygofer for C. ribhoi are presented. Observations on mass emergence of C. ribhoi are described.

Equipped to oxidize nutrients, eurkaryotic cells acquired a 'boost' to cellular energy, enabling the emergence of multi-cellular mammals, sustained by a nearly inexhaustible ...

Abstract Mixed flow compressor stage designs are becoming increasingly popular for use in Micro Gas Turbine (MGT) engines. Due to manufacturing constraints and structural considerations, such compressors typically feature unshrouded impeller designs. A numeric investigation of the effect impeller-shroud tip clearance on performance a MGT mixed fitted with crossover diffuser is presented. Three ...

BACKGROUND Elevated plasma levels of endothelin (ET)-1 have been reported in association with heart diseases, including heart failure. Furthermore, it has been suggested that ET-1 acts as a local autocrine/paracrine factor with biological activities such as vasoconstriction, mitogenesis, and inotropic effects on the heart. This study investigated alterations of ET-1, ET receptor, and endothelin...

Traditional dewatered cassava mash sieving device developed by local craftsmen in Nigeria exposes users to work-related musculoskeletal discomfort (WMSD), among other drawbacks such as low throughput capacity, high energy, and time input. This research seeks develop an improved manual (DCM) machine which alleviates this exposure well enhance productivity. Anthropometric parameters of 150 proces...
