Oral squamous cell carcinoma (OSCC) is a disease of significant concern with higher mortality rates. Conventional treatment approaches have several drawbacks, leading to the opening of new research avenues in the field of nanoparticle-based cancer therapeutics. The study aimed at the synthesis of gold nanoparticles (Pm-AuNPs) from the aqueous bark extract of , followed by its characterization and anticancer evaluation against OSCC.

Background: Metastasis to parapharyngeal space in papillary carcinoma of the thyroid is rare and often missed in routine clinical and radiological investigations. Although contrast CT /MRI can be done to locate the parapharyngeal lesion, the diagnosis of metastasis mostly deepened upon aspiration cytology, which is a challenge in difficult anatomical locations. Here, we have emphasized the management dilemma of parapharyngeal metastasis in papillary carcinoma of the thyroid.

Background: Increasing stroke burden in India demands a long-term stroke surveillance framework. Earlier studies in India were urban-based, short term and provided limited data on stroke incidence and its outcomes. This gap is addressed by the establishment of five population-based stroke registries (PBSRs) of the National Stroke Registry Programme, India.

Background: Head and neck infections (HNI) associated with multidrug resistance (MDR) offer several health issues on a global scale due to inaccurate diagnosis.

Objectives: This study aimed to identify the bacteria and Candidal isolates and implement the silver nanoparticles green synthesized with leaf extract of (Cg-AgNPs) as a therapeutic approach against HNI pathogens.

Methods: The Cg-AgNPs were characterized by the UV-visible spectrophotometer, FT-IR analysis, Zeta particle size, Zeta potential, and field emission scanning electron microscope (FESEM) analysis to validate the synthesis of nanoparticles.

Cadmium telluride (CdTe) semiconductors are used in thin-film photovoltaics, detectors, and other optoelectronic applications. For all technologies, higher efficiency and sensitivity are achieved with reduced charge carrier recombination. In this study, we use state-of-the-art CdTe single crystals and electro-optical measurements to develop a detailed understanding of recombination rate dependence on excitation and temperature in CdTe.

is a commensal yeast. It can be infective when the host's defense mechanism is weakened, as in the case of squamous cell carcinoma patients. We aimed to evaluate the prevalence and clinical mycological manifestation of candidiasis in 150 cancer cases comprised of preoperative and post-operative (with or without radiotherapy) upper aerodigestive squamous cell carcinoma.

Background: There are several physiological changes found in pregnant women and amongst them, otological changes are quite important. The otological manifestations in pregnant women are mainly due to changes of sex hormones levels, which return to normal in the postpartum period.

Objective: To report otological manifestations among pregnant women.

Objective: To determine the prevalence of enuresis and lower urinary tract dysfunction among Indian school children, and describe teachers' perceptions regarding toilet requests.

Methods: Anonymous survey of students of a secondary school in Visakhapatnam, India by a modified version of the Dysfunctional voiding and incontinence scoring system (DVISS) in 2518 parents. Two questionnaires - the Bathroom behaviour scale and Teachers' hassle scale for toilet requests were designed, validated and administered to 138 teachers.

Objective: The objective of this study was to assess the natural history of trigeminal neuralgia (TN) and pretrigeminal neuralgia (PTN) in a hospital-based sample using a retrospective and descriptive study design.

Methods: This study followed a retrospective study design, which yielded a sample size of 216 patients who were reclassified as per the new classification and diagnostic grading for practice and research proposed by the American Academy of Neurology. Based on an in-depth analysis of patient history and the treatments administered, a possible state of PTN prior to TN development was determined.

is an important chronic suppurative otitis media (CSOM) pathogen that exhibits multiple resistances to antibiotics with increasing frequency, making patient treatment more difficult. The aim of the study is to ascertain the genetically diversity of this clinically isolated with inter simple sequence repeat (ISSR) markers. All 25 were isolated from CSOM patients by taking their ear swabs and culturing on blood agar and MacConkey agar.

Introduction: Chronic suppurative otitis media (CSOM) is a common problem in worldwide and untreated CSOM leads to fatal complications like facial nerve paralysis, lateral sinus thrombosis, labyrinthitis, meningitis and brain abscess in developing country like India.

Objective: To isolate causative bacteria and antibiotic sensitivity pattern for CSOM and to know the prevalence of extended spectrum beta lactamases (ESBL) and Metallobetalactamases (MBL) in CSOM patients.

Methods: A total of 500 ear swabs of clinical suspected CSOM patients were cultured on specific cultured medium and identified the bacteria with conventional methods.

Background: Twins are similar in many ways owing to the genetical and environmental factors. However, still, there are certain things that are not similar among them, and this is the challenge for personal identification among the twins.

Objectives: Our present study aimed to know and assess the similarities and differences present between the monozygotic (identical) and dizygotic (fraternal) twins in relation to lip prints, palm prints, fingerprints and blood group and to evaluate their heritability among parents and their offspring.

Cadmium telluride (CdTe) high purity, bulk, crystal ingots doped with phosphorus were grown by the vertical Bridgman melt growth technique to understand and improve dopant solubility and activation. Large net carrier densities have been reproducibly obtained from as-grown ingots, indicating successful incorporation of dopants into the lattice. However, net carrier density values are orders of magnitude lower than the solubility of P in CdTe as reported in literature, 10/cm to 10/cm [J.

Efficient p-type doping in CdTe has remained a critical challenge for decades, limiting the performance of CdTe-based semiconductor devices. Arsenic is a promising p-type dopant; however, reproducible doping with high concentration is difficult and carrier lifetime is low. We systematically studied defect structures in As-doped CdTe using high-purity single crystal wafers to investigate the mechanisms that limit p-type doping.

Introduction: Neurocysticercosis being a potential to human transmitted disease, is the major cause of seizures and a public health problem in tropical countries. Though India is known to be highly endemic, there are many provinces where reports are still unavailable thereby underestimating its actual burden.

Materials And Methods: Anti-Cysticercus IgG antibodies in sera from cases presenting with seizures were screened by ELISA in a preliminary study in Odisha state which is a province in Eastern coastal India that was never explored before.

Histoid Hansen's disease is a rare form of multibacillary leprosy with distinct clinical and histopathological features. This type of leprosy is a variant of lepromatous leprosy with a very high bacterial reserve. Of alarming concern is the discovery of an isolated mucosal histoid leprotic lesion inside the nasal cavity of a patient in the post-global leprosy elimination era.
