The present study was conducted to study the benefit of high frequency tympanometry (HFT) in detecting middle ear pathologies in infants. This study also aims to find the effect of middle ear diseases on absent otoacoustic emissions (OAE). Our study was a prospective study which included 123 healthy neonates below 1 month of age. The babies were referred for the new born hearing screening programme. They were subjected to DPOAE followed by tympanometry with a 1000z probe tone (HFT). The study was approved by the institutions ethical committee. "Present" OAE result was obtained for 202 ears, while "absent" OAE result was obtained for 44 ears. High frequency tympanometry was also performed on all the participants, where a normal tympanogram was obtained in 170 ears and 76 ears showed an abnormal tympanogram. The following parameters were studied: peak pressure, ear canal volume and compliance. Descriptive statistics were obtained for the same. Association of OAE with HFT was studied. Out of the 44 ears with refer OAE, 34 ears had an abnormal tympanogram and among 202 ears with a present OAE, 160 ears had a normal tympanometric peak indicating a sensitivity and specificity of 77.3% and 79.2% respectively. High frequency tympanometry not only helps in early detection of middle ear pathologies but also to find the effect of middle ear diseases on absent otoacoustic emissions.

Melioidosis is a neglected tropical infection caused by the Gram-negative bacterium Burkholderia pseudomallei, which is found in soil and water across tropical countries. The infection spectrum ranges from mild localized lesions to severe sepsis. The clinical presentation, severity, and outcome are influenced by the route of infection, bacterial load, strain virulence, and specific virulence genes of B.

Correlation of Phase Structure, Defect Relaxation, and Microwave Dielectric Properties in Low-Loss MgTiO Ceramic Systems.

ACS Appl Mater Interfaces

January 2025

State Key Laboratory of New Ceramics and Fine Processing, School of Materials Science and Engineering, Tsinghua University, Beijing 100084, China.

Low-loss microwave dielectrics are of significant importance for the miniaturization and integration of microwave devices. In this paper, the ceramics of nominal composition MgTiO ( = 3-6) are synthesized, and the correlations among their phase compositions, defect behaviors, and microwave dielectric properties are systematically investigated. The analyses indicate that the MgTiO ceramics are a biphasic system consisting of hexagonal ilmenite-structured MgTiO and cubic spinel-structured MgTiO.

Epidemiology of gastrointestinal parasites of dogs in four districts of central Ethiopia: Prevalence and risk factors.

PLoS One

January 2025

Department of Pathology & Parasitology, College of Veterinary Medicine and Agriculture, Addis Ababa University, Bishoftu, Ethiopia.

From February 2022 to April 2023, a cross-sectional study on dog gastrointestinal parasites was conducted in Bishoftu, Dukem, Addis Ababa, and Sheno, Central Ethiopia, with the aim of estimating the prevalence and evaluating risk factors. A total of 701 faecal samples were collected and processed using floatation and McMaster techniques. In dogs that were investigated, the overall prevalence of gastrointestinal parasites was 53.
