In this paper, we explore a set of geometric properties of Mixed Super Quasi-Einstein (MSQE) manifolds and provide examples of both Riemannian and Lorentzian MSQE manifolds to demonstrate their existence. Furthermore, we examine MSQE spacetimes in the context of the space-matter tensor, discussing several related properties. Finally, we establish the existence of an MSQE spacetime through a nontrivial example. [ABSTRACT FROM AUTHOR]

In the present paper we study Ricci pseudo-symmetry, Z-Ricci pseudo-symmetry and concircularly pseudo-symmetry conditions on a mixed generalized quasi-Einstein spacetime MG(QE)4. Also, it is proven that if d ≠ Λ, then MG(QE)4 spacetime does not admit heat flux, where d and Λ are the function and the cosmological constant, respectively. In the end of this paper we construct a non-trivial example of MG(QE)4 to prove its existence. [ABSTRACT FROM AUTHOR]

Objective: To find out the frequency of hereditary absence of palmaris longus and flexor digitorum superficialis tendons among individuals visiting physiotherapy clinics of 2 hospitals in Pakistan. Methods: This cross-sectional study was conducted in Government hospitals in twin cities (Islamabad and Rawalpindi), Pakistan from September 2018 to March 2019. For examination, a standardized clinical Schaeffer's test and three additional tests were used for the assessment of palmaris longus (PL), and a standardized simple, and the modified test was used for flexor digitorum superficialis (FDS). Data were analyzed by using SPSS 23. Results: Out of 619 individuals, 51.7% were men and 48.3% women were examined. The mean age of males was 33.4 years ± 14.5 and of females 35.9 years ± 13.4. Palmaris longus muscle was absent in 49.3% of participants with bilateral absence being more common. Unilateral absence of the PL muscle was found to be more in the left hand. Its absence in the left hand was found more common in females than in males (11.7% females, 9.1% males). This research showed agenesis of PL is gender dependent. (p< 0.05), and no association was found among the standard FDS and PL tendon test, that is r (617) =0.046, p= 0.249. Conclusion(s): The absence of palmaris longus muscle is more frequently found in women and in the left hand. Agenesis of FDS is rare in individuals and has no association with agenesis of palmaris longus. [ABSTRACT FROM AUTHOR]

The subject of the present paper is to introduce a type of non- at Riemannian manifold called an almost pseudo Schouten symmetric manifold A(PSS)n. Some geometric properties have been studied of this manifold. Also, the existence of such a manifold is ensured by a non-trivial example. Finally, we have studied about hypersurface of an A(PSS)n.

Objectives: (1) To assess the diagnostic accuracy of narrow-band imaging (NBI) in the assessment of benign, premalignant, and malignant vocal fold lesions. (2) To evaluate the diagnostic value of NBI in detection of recurrence in upper aero-digestive tract malignancy.Methods: This was a prospective, observational study done between December 2018- November 2019 in the Department of Otolaryngology. One hundred six patients of suspected benign, premalignant, malignant lesions of larynx and hypopharynx along with recurrence cases of upper aerodigestive tract malignancy who have completed chemoradiation therapy. All patients were subjected to white light endoscopy (WLE), NBI, and biopsy for histopathological diagnosis. In WLE, laryngeal lesions were classified into three types: malignant, suspected malignant, and benign. NBI images were classified into 5 types based on the intrapapillary capillary loop (IPCL) patterns: Type I-IV were considered benign and Type V lesion was considered malignant. At the end, WLE and NBI findings were correlated with histopathological reports.Results: The diagnostic accuracy of NBI in diagnosing benign, premalignant, and malignant lesions is significantly better than WLE. The sensitivity of NBI in detecting malignant lesions is significantly greater than WLE. NBI has proved to be of great value in identifying lesions that could be missed by WLE alone, as combined sensitivity of NBI and WLE is significantly higher than WLE alone.Conclusion: NBI is an excellent technique for early detection of laryngopharyngeal malignancies with significantly higher sensitivity than WLE alone.
