Personality Traits in Kovurkizhar Songs

Kovoorkizhar was one of the most scholarly poets of the Sangam age. He is one of the 15 Kizhar poets in the Purananooru. Supported by the Chola dynasty, he was of the view that there should be love, righteousness, and peace in politics. It is to be seen from his Purananooru songs in this thesis that the ruling kings, however, kept their anger aside and worked diligently to change their wrong policies and make them better. There are 15 songs in Purananooru sung by him. Of these, the four songs from 44 to 47 in the Purananooru can identify his personality traits. The songs were performed in person by the four Chola kings (Nalankilli, Nedunkilli, Kulamuruthathu, Thunjiya Killivalavan, and Kurapalli Thunjiya Killivalavan) speak volumes about their power and virtues. He has also highlighted the personality traits of the kings featured in those songs. It is to be noted that Kovoor Kizhar sang two of the six songs (68 and 70) in Purananooru about the field of Panatruppadai. It is explained in this review that the poets featured in these songs were selfless and respected the welfare of others. Along with these, a song (308) is featured in the Mullaithurai of Moodin, sung by Kovoorkizhar. This thesis describes the lives of the Panars and the great power of the King of Seerur

Seroma formation after modified radical mastectomy: analysing risk factors and incidence

Background: Breast cancer is a prevalent form that affects women and is a leading cause of death among women. The development of seroma is a frequent complication that can arise after breast cancer surgery, and its underlying mechanisms are still not fully understood. Consequently, data was collected to analyze the occurrence and factors that contribute to the development of seroma in patients. We aimed to enhance our comprehension and ultimately discover methods to mitigate it. Methods: A prospective group research study was conducted on a sample of 86 female patients who underwent mastectomy from August 2020 to August 2023. This study was carried out as part of the senior residency program at Nalanda Medical College and Hospital in Patna, Bihar, India. Patients who develop seroma within four weeks of surgery are usually recommended to undergo, specifically ultrasonography, and radiological evaluation to determine the size. Results: 27 out of 86 patients (31%) were found to have seroma. Several factors are closely linked to the development of seroma. Factors that may contribute to increased risk The minimum age at which seroma production occurs following MRM ≥56 or older, having a BMI of 26.50 or higher, a tumour measuring 4 cm or larger undergoing the removal of more than 12 lymph nodes, and having a level 3 axillary dissection. Conclusions: After surgery, a certain group of people in the study experienced seroma formation within four weeks. These individuals had undergone MRM. Age, BMI, tumour size, level 3 axillary dissection, the removal of more than 12 lymph nodes during surgery, and the occurrence of seroma after MRM were found to be positively correlated. There was no observed connection between seroma production and a range of factors, such as neoadjuvant chemotherapy, the timing of drain removal, shoulder workouts, and the use of breast bandages

Intestinal obstruction caused by tuberculosis: unmasking a silent risk

Background: Intestinal tuberculosis (TB) remains a global health challenge, especially in regions with a high TB prevalence. This manifestation, distinct from pulmonary TB, involves the gastrointestinal tract, often leading to intestinal obstruction. The study addresses the insidious nature of the disease, emphasizing the urgency for timely diagnosis and intervention. Recognizing the multifaceted impact of TB on various organs, the study explores the pathophysiology, clinical presentation, and diagnostic complexities of intestinal TB. Methods: This study was conducted at Nalanda medical college and hospital in Patna, Bihar, India, the retrospective study spans three years focusing on 127 patients with intestinal obstruction due to TB. Inclusion criteria prioritized histopathological confirmation of TB, ensuring cohort accuracy. The study employed preliminary investigations, including hemogram, chest X-ray, abdominal X-ray, ultrasonogram, sputum examination, and Mantoux test and CECT whole abdomen. Clinical presentations were systematically analyzed, guiding tailored management protocols based on the mode of presentation. Results: Demographically, the study identified TB as the cause in 127 cases, with a balanced gender distribution and a peak incidence in the 21-30 years age group. Presentations varied, predominantly with acute symptoms. Common complaints included abdominal pain, vomiting, constipation, and distension. Surgical intervention within 24 hours was crucial in 61.1% of cases. Intraoperatively, findings comprised mesenteric thickening, lymph nodal enlargement, and adhesions. Adhesionolysis was the primary procedure. Postoperative complications, mainly wound infections, were noted but had a limited impact on mortality. Conclusions: This study reveals TB as a significant contributor to intestinal obstruction, emphasizing challenges in early diagnosis. Adhesionolysis emerges as a key operative procedure, underscoring the need for surgical flexibility. Postoperative complications, while notable, have minimal impact on mortality

Ceftaroline fosamil in the treatment of methicillin-resistant Staphylococcus aureus

Ceftaroline fosamil, a cephalosporin approved by the FDA for treating infections caused by methicillin-resistant Staphylococcus aureus (MRSA). Staphylococcus aureus, particularly MRSA strains, poses a significant health risk due to antibiotic resistance. Ceftaroline fosamil is unique in its ability to bind to penicillin-binding protein 2a (PBP2a) found in MRSA, inhibiting bacterial cell wall synthesis and causing bacterial death. The pharmacokinetics of ceftaroline involve rapid conversion to its active form, primarily excretion through the kidneys, and a plasma protein binding rate of approximately 20%. Ceftaroline is effective against complex skin and soft tissue infections (cSSTIs) and community-acquired pneumonia (CAP), especially when MRSA is suspected. However, its efficacy against gram-negative bacteria is limited. The safety profile of ceftaroline fosamil is generally good, with reported adverse events comparable to other comparator agents in clinical trials. It is contraindicated in individuals with hypersensitivity to cephalosporins. Comparative efficacy with other antibiotics like vancomycin and daptomycin is discussed, emphasizing the importance of considering individual patient characteristics and local prevalence of resistant bacteria. The use of ceftaroline fosamil in special populations, such as pediatric and adult patients. While its efficacy in pediatric MRSA infections is explored, the lack of large-scale clinical trials for certain conditions like MRSA bacteremia is acknowledged. Clinical outcomes, including successful treatment of MRSA bacteremia, infective endocarditis, central nervous system infections, and nosocomial pneumonia, are discussed, suggesting ceftaroline fosamil's potential as a valuable therapeutic option. The conclusion underscores its breakthrough status, offering hope in addressing MRSA infections and improving patient outcomes

Effect of Loading Densities in Closed Vessel Tests on the Burning Rate of a Propelling Charge

Closed vessel firing of gun propellant at different loading densities is conducted for evaluation of its ballistic parameters. Although in actual gun applications, loading densities are higher, but for closed vessel evaluation standard loading density is taken as 0.2 g/cc for interior ballistic calculations of guns. Closed vessel evaluation of standard triple-base propellant in hepta-tubular configuration with loading density varying in the range of 0.2 g/cc to 0.3 g/cc is conducted for the evaluation of salient ballistic parameters. It is observed that maximum pressure increases with increase in loading density of propellants. As loading density increases, rate of rise of pressure also increases. Accordingly, a rise in burning rate is also observed. However, the burning rate index (α) and coefficient (β) of the power law of burning (r = βPα) is found independent of loading density. The average values of these burning rate parameters are calculated as (α =) 0.78 and (β =) 0.45 for the studied propellant.Defence Science Journal, Vol. 65, No. 2, March 2015, pp.126-130, DOI:http://dx.doi.org/10.14429/dsj.65.815

Synthesis, x-ray crystal structures and biological evaluation of some mono- and bi-cyclic 1,3-diazetidin-2-ones: non-natural β -lactam analogues

Mono- and bi-cyclic 1,3-diazetidin-2-ones (aza-β -lactams) are synthesised and evaluated as non-natural analogues of β -lactams. The aza-β -lactams are designed on the principle that their reaction with active site serine hydroxy will form a carbamoyl-enzyme intermediate that is sluggish to hydrolysis. The synthesis of racemic mono- and bi-cyclic aza-β -lactams is carried out starting from pyrimidinone 18 which is transformed to the densely functionalised substrate 20. The chemical reactivity of tricarbonyl 20 for selective functional group manipulation was first assessed and then it was transformed to amino alcohol 24. Cyclisation of 24 affords aza-carbapenams and its homologation followed by aldol cyclisation provides access to aza-carbacephams. The X-ray structures of aza-carbapenam 35 and aza-carbacepham 42 suggest that the structural requirements for biological activity in β -lactams are fulfilled. An unexpected ozonolysis product, phenol 52 resolves spontaneously during crystallisation and its crystal structure was also determined. The biological activity of the novel mono- and bi-cyclic aza-β -lactams was evaluated with potent gram-positive bacterial strain, Bacillus subtilis and compared with β -lactam antibiotics, ampicillin and penicillin G. Of the 19 aza-β -lactams tested, eight compounds show inhibition better than the standards while another eight are of comparable activity. This study shows that aza-β -lactams represent a novel and non-natural lead towards serine peptidase inhibitors
