Regulatory role of PA3299.1 small RNA in Pseudomonas aeruginosa biofilm formation via modulation of algU and mucA expression.

Small RNAs (sRNAs) have emerged as key regulators of transcriptional factors and components within regulatory networks that govern bacterial biofilm formation. This study aimed to explore the regulatory role of the PA3299.1 sRNA in controlling biofilm formation in P.

Comparison of intravenous dexmedetomidine and ketamine with femoral nerve block for positional pain before spinal anaesthesia in patients with fracture femur: A prospective randomised study.

Introduction: Patient positioning for spinal anaesthesia in patients with femur fracture is extremely painful and various methods have been tried to reduce mobilisation pain.

Aim: To compare the analgesic efficacy of intravenous dexmedetomidine, ketamine and femoral nerve block in patients posted for fractured femur for alleviating the positional pain before spinal anaesthesia.

Materials And Methods: A total of 75 patients (25 per group) of American Society of Anaesthetists Grade I-III patients of age group 18-80 years with fractured femur scheduled for elective surgery.

Comparison of the effect of intraoperative dexmedetomidine versus ketamine on postoperative analgesia in fracture femur patients operated under subarachnoid block - A prospective randomized double-blind controlled trial.

Background And Aims: Intravenous sedation during spinal anesthesia has the advantages of increased duration of spinal anesthesia and better postoperative pain control. The aim of this study was to compare the effect of intravenous bolus and infusion of dexmedetomidine versus ketamine given intraoperative on the postoperative analgesia in fracture femur patients operated under subarachnoid block.

Material And Methods: In this prospective randomized double-blind controlled study, 75 patients aged 18-65 years posted for elective surgery were selected and randomly divided into three groups to receive ketamine (group K), dexmedetomidine (group D), and saline (control group C).

On-the-spot spirometry & combined salbutamol & glycopyrronium reversibility testing in obstructive airway disease: A real-world appraisal.

Background & objectives Spirometric glycopyrronium responsiveness, a new advent, needs to be examined at in terms of degree and frequency in different obstructive-airway diseases diagnosed in real world practise. Methods Serial and willing symptomatic affected individuals of suspected airway disease underwent a pragmatic post-consultation spirometry-protocol on the same day with salbutamol followed by glycopyrronium bromide. The diagnosis of asthma (FEV1-reversibility ≥ 200 ml + 12%), chronic obstructive pulmonary disease (COPD) (FEV1/FVC<0.

Endophytes as bioenhancers of plant growth: An overview.

The need for food production rises with the era of expanding population. As a result, there is more indirect demand for chemical pesticides and fertilizers. Serious environmental concerns result from the continuous and careless usage of chemicals.
