Phenotypic Plasticity: The Best Approach for Stress Selection | Chapter 10 | Advances and Trends in Agricultural Sciences Vol. 1

The abiotic stresses are the main factors associated to low productivity, since they are related to the soil and the conditions of the environmental adversities. These are difficult to control factors and when severely affects production dramatically. The expand agricultural production to new crop areas in the tropical regions is an important strategy to supply the huge demand for food and renewable energy sources. However toxic aluminum (Al) present in tropical soils is a limiting factor for agricultural production. The objective of this study was to identify Al-tolerant and Al-sensitive sugarcane genotypes, based on phenotypic plasticity. Eleven sugarcane genotypes were evaluated under non-stress and Al-stress conditions. Genetic variability regarding Al tolerance was observed among the sugarcane genotypes by phenotypic plasticity. Al-stress caused a reduction in the primary root length and in the shoot dry weight, but an increase in the lateral root length. There was a difference between the genotypes related to Al accumulation in the roots and shoot, suggesting the existence of distinct tolerance mechanisms. Based on phenotypic plasticity genotypes can be classified as tolerant or sensitive to Al. The phenotypic plasticity is a simple form of analysis; however, it has great information about the behavior of the genotype. We characterized genotypes associated with Al-stress. The characterization of contrasting genotypes will be important for breeding programs involving sugarcane yield in regions subjected to stress.

A Brief Study of Middleware Technologies: Programming Applications and Management Systems | Chapter 15 | Novel Research Aspects in Mathematical and Computer Science Vol. 1

  Many platforms, services, applications, hardware, and operating systems are connected through the middleware layer. Because the middleware layer abstracts much low-level complexity and makes applications and software systems portable, it allows disparate systems to interface and function together in harmony. Middleware technologies enable software engineers to swiftly construct software systems and applications, allowing developers to focus on more important tasks. This chapter examines several types of middleware systems and discusses middleware capabilities, middleware operation, middleware's function in cloud-based systems, and the best middleware platforms to use. Middleware systems are widely utilised and can be found in practically any software system or application. Middleware programmes provide as a link between many sorts of systems and protocols. They serve as a mechanism for various systems. To successfully exchange information, it runs on a variety of operating system

A Prospective Study about Safety and Efficacy of Perioperative Lidocaine Infusion | Chapter 09 | New Horizons in Medicine and Medical Research Vol. 8

 Opioids cause clinically significant side effects such as respiratory depression, immunosuppression, muscle rigidity, negative inotropism, nausea, vomiting, hyperalgesia, urine retention, postoperative ileus, and drowsiness. Perioperative opioids are a major contributor to the United States' and other countries' opioid epidemics. Non-opioid analgesics, particularly lidocaine, are becoming more common for perioperative use as a result of this. A total of 185 adult patients were randomly assigned to one of two groups: control group I (105 patients) [fentanyl group] or group ii (80 patients) [opioid-free anaesthesia group]. Lidocaine 1.5 mg/kg bolus followed by 1.5 mg/kg/h infusion intraoperatively, and 1.5-2 mg/kg/h infusion for 2-8 hours postoperatively were given to patients in both groups at anaesthetic induction. Intraoperatively, both groups received analgesic adjuvants such as diclofenac 75 mg, paracetamol 1 gm, and mgso4 30-50 mg/kg. If the mean arterial pressure (map)

Scientific values of ECA Ligation | Chapter 06 | New Horizons in Medicine and Medical Research Vol. 8

  Previously, carotid artery ligation was done as an emergency procedure to stop severe haemorrhages in the head and neck. Despite this, it was abandoned because to high patient mortality and morbidity. However, ECA ligation, a more selective branch of the carotid artery, has been popular for the same goal in recent decades due to the lack of or modest postsurgical problems compared to Transarterial embolization (TAE). However, a good surge seal pack, especially in the maxilla, is occasionally required to regulate both collateral circulation and backflow of blood from the internal carotid arteries distal to the carotid arteries (ICA). ECA ligation, on the other hand, might be a superior alternative for controlling life-threatening uncontrolled bleeding in this area.
