Ischemia time during partial nephrectomy is strongly associated with acute and chronic renal injury. ATP depletion during warm ischemia inhibits ATP-dependent processes, resulting in cell swelling, cytoskeletal breakdown, and cell death. The duration of ischemia tolerated by the kidney depends on the amount of ATP that can be produced with residual substrates and oxygen in the tissue to sustain...
within communicative, interactive, and learner-centered framework of language teaching and learning, students need to learn four skills of listening, speaking, reading, and writing for their educational success. but of all the language skills, reading enjoys a paramount significance in so many second or foreign language academic contexts. in spite of its importance, language learners still have...
1. The participation of neural mechanisms in mediating the renin release induced by reduction of renal perfusion pressure was explored in anaesthetized cats by comparing renin release from the two kidneys, one acutely denervated and the other intact. 2. Suprarenal aortic stenosis of 10 min duration reduced renal perfusion pressure to 50 mmHg and halved blood flow to both kidneys, but cause a gr...
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
Objective- The objective of the present study was to determine the changes in heart rate, respiratory rate and arterial Oxygen saturation (SpO2) by administration of three drug combinations during upper gastrointestinal endoscopy. Design- Experimental study. Animals- 21 healthy and adults dog were randomly divided into three groups. Procedures- The IV combination of 6.5 mg/kg ketamine and 0....
Abstract This study aimed to examine intra-individual differences in both duration and passage of time (PoT) judgments, the relationships between them, for a wide range durations going from few hundred milliseconds several minutes. Participants performed with within-subjects design (200–400 ms), seconds (2–4 s), tens (20–40 s) minutes min) ranges. For results revealed individual temporal accura...
it is definitely necessary to understand the concept and behavior of causation of life insurance policies and its determinants for insurance managers, regulators, and customers. for insurance managers, the profitability and liquidity of insurers can be increasingly influenced by the number of causation through costs, adverse selection, and cash surrender values. therefore, causation is a materi...
Background: Various studies have investigated the role of different drugs as adjuncts to SBPB to prolong the duration and quality of analgesia without producing any major adverse effects. We conducted a study to compare the novel alpha 2 agonists (clonidine and dexmedetomidine) with respect to onset, duration of block and postoperative analgesia when added as adjuvants to the local anesthetic 0...
soil erosion is an abstruse phenomenon which contains segregation and transmission of soil particles and runoff from rainfall and infiltration. runoff and sediment generation was compared using rainfall simulator in grassland (st. parviflora-br. tomentellus) and shrubland (as. parrowianus-as. gossipinus). for this purpose, vegetation map was supplied for two vegetation types four main aspects a...
