Osmia (Pyrosmia) Tkalců, previously known only from the Palaearctic region, is reported for the first time from India, specifically from northern India, which marks the confluence of the Palaearctic and Indo-Malayan realms and therefore, has a mixture of species from both. This is the third subgenus of Osmia Panzer after Osmia (Helicosmia) Thomson and Osmia (Osmia s.str.

Article Synopsis
  • Urban rodents at Kolkata's Alipore Railway Station were studied for their role in spreading zoonotic pathogens, particularly Bartonella spp., through fleas, highlighting the link between high rodent populations and increased disease risk due to nearby human activity.
  • The study involved collecting and identifying rodents and fleas, as well as detecting Bartonella DNA to understand its prevalence and phylogenetic relationships among different species.
  • Results showed a high prevalence of Bartonella infections in rodents (53.33%) and fleas (79.1%), with some haplotypes indicating cross-species transmission between rodents, fleas, and humans, underscoring the public health implications of these findings.

Mucormycosis is a rare, opportunistic fungal infection prevalent in the elderly, especially in patients with uncontrolled diabetes or a compromised immune system. However, the outbreak of the pandemic declared by the World Health Organization in late 2019 increased the incidence of mucormycosis cases in COVID-19 patients due to increased steroid usage that resulted in an immunocompromised state. The current report presents two cases of oral mucormycotic osteomyelitis in patients who developed diabetes post-COVID infection, along with a review and relevant literature.

Formerly believed to be a subtype of odontogenic keratocyst (OKC), orthokeratinized odontogenic cyst (OOC), a rare developing odontogenic cyst, is now believed to be distinct. The clinical, radiographic, histological data are included in this report, along with a review of the literature to aid in comprehending the cyst. A retrospective search in the oral pathology department between 2018 and 2022 was conducted to recover all cases reported as OOC in SRM Dental College, Ramapuram.

Background: Serum urea levels are essential for the diagnosis of chronic kidney disease (CKD), as they are a measure of renal function. Salivary urea has been used as an alternative to serum urea in patients with CKD.

Aim: To estimate serum urea levels and their correlation with salivary urea levels in order to validate the use of saliva as an alternative diagnostic tool for renal dysfunction.

Cerium dioxide (CeO) based nanomaterials have emerged as promising dermal equivalents, promoting fibroblast infiltration and tissues regeneration. To enhance the antibacterial and wound healing activity, herein chitosan (CS)-CeO combined nano titanium dioxide (TiO) complex loaded polycaprolactone (PCL) nanohybrid (CS-CeO/TiO/PCL) scaffolds were prepared through casting method. The nanohybrid scaffolds' physiochemical, morphological, mechanical, and biological properties were evaluated using advanced analytical techniques.

Aim: To assess the expression of PGC1-α and PGC1-β in Oral squamous cell carcinoma in the presence and absence of hyperglycemia.

Materials And Methods: Fresh tissue samples were collected from 14 well differentiated OSCC patients with hyperglycemia, 14 OSCC patients without hyperglycemia  and 14 healthy controls and subjected to quantitative real-time PCR to assess expression of PGC1-α and PGC1-β. The relative gene expression of PGC1-α and PGC1-β was calculated using the double delta Ct method.

Background: Dentin caries involves dissolution of minerals which eventually leads to degradation of organic matrix. This degradation which was thought to be by bacterial proteases is now considered to be orchestrated by endogenous collagenases such as Matrix Metalloproteinases (MMPs). This paper aims to estimate the salivary levels of MMP-8 in dental caries and also to asses the various risk factors that contribute to the formation of dental caries.

The Aim Of The Study: Human papillomavirus (HPV) is an oncogenic virus and the high-risk genotype HPV 16 and 18 are the most commonly associated with carcinoma. The aim of the study is to determine the prevalence of HPV 16 and 18 in normal oral mucosa, potentially malignant oral disorders (PMOD), and in oral squamous cell carcinoma (OSCC) in South Indian population and whether it can be used as a biological marker to identify the severity of the disease in patients.

Materials And Methods: Cytological samples from buccal mucosa were obtained from ten OSCC patients, ten patients with PMOD, and ten from control group.

Background: Sexual dimorphism in teeth has been an area of research for forensic anthropologists. The function of root in transmitting the forces of occlusion to the alveolar bone varies as the force in males tends to be larger than in females. This shows the significance of the root length as indicators of sexual dimorphism.
