Background And Aims: Succinylcholine is the only available depolarizing neuromuscular blocker that has been widely used in the induction of anesthesia, and it is the drug of choice for rapid-sequence induction of anesthesia due to its rapid onset of effect and ultrashort duration of action owing to its rapid hydrolysis by acetyl-cholinesterase. Postoperative muscle pain (myalgia) and muscle stiffness are the most common side effects and are observed most frequently on the 1 postoperative day in ambulatory surgery. The use of succinylcholine in the induction of anesthesia and intubation in routine cases has been discouraged because of such adverse effects.

However, various side effects and complications of GA, such as postoperative pain, nausea, vomiting, and increased hospital stay increase morbidity in patients. Regional anaesthesia using multiple injection paravertebral block is an ideal alternative to GA for breast surgeries.

Materials And Methods: A cross-sectional study was conducted among dental UG students from five dental colleges. Snowball sampling was used to approach 776 potential participants, resulting in a complete response from 507 students.
Background: The anterior-middle superior alveolar (AMSA) anesthetic technique has been reported to be a less traumatic alternative to several conventional nerve blocks and local infiltration for anesthesia of the maxillary teeth, their periodontium, and the palate. However, its anatomic basis remains controversial. The present study aimed to determine if the pattern of cortical and cancellous bone density in the maxillary premolar region can provide a rationale for the success of the AMSA anesthetic technique.

Periodontal procedures require adequate anesthesia not only to ensure the patient's comfort but also to enhance the operator's performance and minimize chair time. In the maxilla, anesthesia is often achieved using highly traumatic nerve blocks, apart from multiple local infiltrations through the buccal vestibule. In recent years, anterior middle superior alveolar (AMSA) field block has been claimed to be a less traumatic alternative to several of these conventional injections, and it has many other advantages.

Glucose control plays an important role in the pro-oxidant/antioxidant balance. Some antidiabetic agents may by themselves have antioxidant properties independently of their role on glucose control.

Materials And Methods: MPBL was evaluated for anti-inflammatory activity using carrageenan-induced hind paw edema model. Analgesic activity of MPBL was evaluated by hot plate, writhing, and formalin tests.
Janssen created a classical theory based on calculus to estimate static vertical and horizontal pressures within beds of bulk corn. Even today, his equations are widely used to calculate static loadings imposed by granular materials stored in bins. Many standards such as American Concrete Institute (ACI) 313, American Society of Agricultural and Biological Engineers EP 433, German DIN 1055, Canadian Farm Building Code (CFBC), European Code (ENV 1991-4), and Australian Code AS 3774 incorporated Janssen's equations as the standards for static load calculations on bins.

The structures of the two compounds were confirmed by analysis of their IR, (1)H-NMR, (13)C-NMR and LC-MS spectral data. The mixture of beta-amyrin and 12-oleanene 3beta, 21beta-diol (compound 1) was highly effective against the larvae of the mosquito, Culex quinquefasciatus Say (Diptera: Culicidae), as a mosquitocide.

The structures of the two compounds were confirmed by IR, (1)H-NMR, (13)C-NMR and LC-MS spectral data. The chloroform soluble fraction of stem and ethanol extract of fruits possess potent antishigellosis activity and also exhibited moderate activity against some pathogenic bacteria and fungi but the isolated compound 1 (mixture of β-Amyrin and 12-Oleanene 3β, 21β-diol) showed mild to moderate inhibitory activity to microbial growth.
