Genetic Diversity and Fine-scale Genetic Structure in Syagrus oleracea (Mart.) Becc.: A Survivor Palm Species of the Semiarid | Chapter 09 | Research and Development in Agricultural Sciences Vol. 1

The species Syagrus oleracea is a native palm tree, present in highly impacted environments of the Brazilian semiarid. This species is exploited for use in the manufacture of folk crafts and for human and animal feeding. The objective of this study was to characterize the diversity and genetic structure of individuals from different populations, located in anthropic regions of the Brazilian semiarid region, in the state of Minas Gerais. This information is important for species management and conservation strategies. Thus, we used ISSR molecular markers in 157 individuals in seven populations of S. oleracea. Looking at the results, one can observe that amplifications of 109 locos occurred and that an average of 18, 17 alleles were found on each primer, values that demonstrated that the ISSR technique used was highly efficient. The genetic diversity indexes were observed, showing expected heterozygosity (He) and Shannon index (I) of 0.260 and 0.383, respectively. The number of alleles observed (na) among populations was 1.954 and the effective number of alleles (ne) was 1,606. Individuals of the populations are genetically structured in groups (demes) in a random and aggregate manner. We obtained the amplification of 109 ISSR loci, with a mean of 18.2 alleles per primer. The genetic diversity indexes revealed expected heterozygosity (He) and Shannon index (I) of 0.260 and 0.383, respectively. The number of alleles observed (na) was 1.954 and the effective number of alleles (ne) was 1.606. The value of the indirect gene flow found was 1.546. Evidence of high levels of kinship in populations was found, possibly due to low migration rates and geographical barrier. In addition, we observed signs of overexploitation in the areas, which consequently leads to a low rate of gene flow, occurring inbreeding among the sampled populations of Syagrus oleracea.

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
