Biology, Chemical Composition, Cultivation and Applications of Cacti from the Opuntia Genus | Chapter 09 | Advances in Applied Science and Technology Vol. 5

In this review, we approached various aspects of Opuntia sp. that are a type of forage cacti. These plants stand out for its energy potential and have peculiar morphological and physiological features that  allow  tolerance  for  long  periods  of  drought.  In  addition,  Opuntia  species  has  a  cosmopolitan distribution, found mainly in arid and semi-arid regions. Opuntia sp. presents phenotypic variations related  to  weather  conditions,  like  polyploidy  occurring  in  a  large  number  of  populations  and  high hybridization capacity.  These  plants  have  a  shrub  morphological  characteristic  with  ramifications, variable size, from creeping until arboreal; it can reach up to 4 m high and a series of fleshy stems with, depending on time of year, flowers and fruits. Opuntia sp. have a typical physiology with the photosynthetic process called crassulacean acid metabolism (CAM); stomata close during the day in order to maintain hydration of tissues. The chemical composition of Opuntia sp. varies according to species,  age  of  reticule, and  season.  These  cacti  have  excellent  nutritional  value  with  high  water content (about 90%), digestibility in vitro (about 75%) and vitamin A; in addition, they have organic matter  (67%),  energy  (2,61  Mcal.kg-1),  crude  fiber  (4.3%),  phosphorus  (0.08  to  0.18%),  calcium (4.2%), potassium (2.3%)  and  magnesium (1.4%), but shows low protein  content (about 5%). The proper yield of the crop needs a climate with 400-800 mm annual rainfall, relative humidity above 40% and day/night  temperature  from  25  to  15°C.  The wide  variety  of  applications  demonstrates  the versatility of this plant species, being used in food and feed, agriculture, medicine, pharmaceutical and cosmetic industries, in water and wastewater treatments, and even as insecticide agent. Opuntia genus comprises about 1500 species and O. ficus indica is the most important as forage and human uses.

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)

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

Patients’ Perspective of Acute Post-operative Pain Management: A Multicentre Survey of Tertiary Hospitals in Maharashtra, India | Chapter 08 | New Horizons in Medicine and Medical Research Vol. 8

 When postoperative pain is adequately controlled, patients' satisfaction and patient-related outcomes (PROs) increase. Understanding the patients' perspective is crucial since it supports in the formulation of improvement strategies. Because wrong attitudes and assumptions might block pain alleviation, patients' attitudes and beliefs are critical. As a result, a multicenter study of patients' attitudes, beliefs, experiences, and satisfaction levels with acute postoperative pain management was done in Maharashtra's tertiary hospitals. In addition, the responses were examined to evaluate if the Acute Pain Service (APS) resulted in improved patient outcomes and satisfaction. A 13-item questionnaire adapted from previous studies was used to capture patients' experiences with postoperative pain treatment. The responses of 179 patients are included in the study. The findings revealed that 91.6 percent of patients experienced postoperative pain, with 75.5 percent
